Harold F. Pitcairn, American aviation and Autogiro pioneer, died from a single gunshot wound to the head in the late evening hours of April 23, 1960 at the age of 62 after a gala evening at which he presided over a celebration attended by more than 450 guests for his brother's Raymond's 75th birthday. Initially labelled a suicide by the press, Pitcairn's widow Clara declared that "she never wanted to hear another word about the tragedy", while friends and friendly local authorities made the argument, duly reported by Frank Kingston Smith in Legacy of Wings, his devotional Pitcairn biography (subsidized by the Pitcairn family), that the death was accidental because "there was no note, no indication of depression or unhappiness" and "the police investigation disclosed that two shots had been fired; one had penetrated the ceiling directly over the desk in the first floor study, another had struck Pitcairn in the eye" and that "the next morning it was discovered the semi-automatic pistol was defective: when cocked, it had a supersensitive "hair trigger," and it had a faulty disconnector so that it would fire more than one shot at a time, a condition known as "doubling."" The Pitcairn families, prominent and powerful, prevailed upon the local authorities to declare the death accidental and Kingston Smith's 1981account became the de facto authoritative story of the death of Harold F. Pitcairn. With the perspective, however, of six decades, it appears far more likely that Pitcairn's death was a suicide for reasons that were not readily evident, minimized, unappreciated or deliberately ignored at the time to craft a result that met the needs of Clara Pitcairn and her surviving family. These included the fact that while the claim was made that Pitcairn was making his nightly rounds to check on the estate’s ground-level windows (and had been doing so since the Lindbergh kidnapping in 1932), he actually died at his desk; that those in the house only reported a single shot; the 1907 Savage pistol had no reputation for a hair-trigger, and had not evidenced such a flaw in almost three decades of Pitcairn's nightly ritual; that even though Pitcairn had been assured that his almost-decade-long lawsuit against the United States government for Patent infringement of his Autogiro patents was going well, he was concerned about the impact this lawsuit was having on his aged associates who had been called to give depositions and he had voiced the sentiment that "if he had known that he would have to sue the government, he would not have gone into the Autogiro business"; that the lawsuit, itself intended as a vindication of Pitcairn's contribution to aviation was dragging on and would reach its first legal conclusion in 1967, and not finally conclude upon appeal until 1977; and most importantly, those who deny suicide and point to Pitcairn’s state-of-mind, have failed to take into account when the death occurred or ready evidence of his 'state of mind' To fail to see the tragic end of Harold F. Pitcairn is to forget that 29 years and one day earlier, he had been recognized for "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." The memory of that day on the White House back lawn with the President was the high point of his life even as Pitcairn prepared to celebrate his older brother's achievements. The evidence, when marshalled and documented, conclusively points to suicide - a death of an American aviation pioneer before his contributions were vindicated in the largest patent infringement judgement against the United States in history. To fail to see the tragic end of Harold F. Pitcairn is to forget that 29 years earlier, he had been recognized for "the greatest achievement in aeronautics or astronautics in America".

A “STEP” Forward for Product Lifecycle Management19AERP10_0210/1/2019
The existence of countless proprietary file formats and the exchange of 3D CAD data has been a significant problem since the beginning of 3D CAD modeling. CAD applications and methods using digital data are constantly changing, which predicates the need for a solution to share validated and accurately translated data. Thus the birth of STEP242. Companies who are adopting model-based processes and tools within their organizations are using ISO 10303 STEP Application Protocols AP242 and AP239 for both exchanging data as well as maintaining data for archival and retrieval. Long Term Data Archival and Retrieval (LOTAR) (http://www.lotar-international.org) is an International project sponsored by multiple consortiums for the standardization of the archival and retrieval of digital product and technical data. This project is ISO compliant and works across multi-CAD environments enabling stake holders to share 3D data within a Model-Based Environment (MBE) or a digital enterprise. To ensure the preservation of design intent, validation properties that include geometric shape representation, assembly features, saved views, user-defined attributes, color, visibility, and Product & Manufacturing Information (PMI) 3D data need to be verified and validated for compliance. The culmination of these standards is allowing companies around the globe to manage interoperability with fewer challenges.

CFD Investigation of the Impact of Electrical Heating on the Light-off of a Diesel Oxidation Catalyst2018-01-09614/3/2018
In the last years, as a response to the more and more restrictive emission legislation, new devices (SRC, DOC, NOx-trap, DPF) have been progressively introduced as standard components of modern after-treatment system for Diesel engines. In addition, the adoption of electrical heating is nowadays regarded with interest as an effective solution to promote the light-off of the catalyst at low temperature, especially at the start-up of the engine and during the low load operation of the engine typical of the urban drive. In this work, a state-of-the-art 48 V electrical heated catalyst is considered, in order to investigate its effect in increasing the abatement efficiency of a standard DOC. The electrical heating device considered is based on a metallic support, arranged in a spiral layout, and it is heated by the Joule effect due to the passage of the electrical current. As a result of the spiral arrangement, the distribution of the heat source on the heating section is not uniform, determining a certain spatial distribution of the temperature of the gas entering the DOC section. This has also an influence on the pollutant conversion, both in term of light-off time and overall conversion. In order to simulate the after-treatment system, a suitable CFD framework has been implemented on the basis of the open-source OpenFOAM code. In particular, it is based on a multi-region approach, where overlapping meshes, describing fluid and solid regions, are employed in order to model the presence of porous substrates. Specific models are implemented in order to couple fluid and solid regions in terms of heat-transfer and mass-transfer. Catalytic reaction model is introduced in order to describe the chemical surface reactions occurring on the washcoat of the porous substrate. The model is firstly validated resorting to experimental data. Then, it is applied for the investigation of the effects of the electrical heating on the pollutant abatement, with particular focus on the effects of the non-uniform temperature distribution related to different layouts of the heating spirals. The study points out the benefits related to the adoption of the electrical heating in terms of reduction of the overall pollutant emissions over the RDE cycle. Moreover, the effects of the non-uniform heating is investigated, showing a certain role in promoting the light-off of the reactions as a consequence of the formation of hot spots in the catalyst.

Drink & drive has caused the increased rate of commercial vehicle accidents in the world due to the slow response to judgment and reasoning. According to research study 70% accidents are happened due to drunk & drive, it causes loss of human life and economic damage. Research has proven that drunk drivers exhibit aggressive driving behavior and apply more force during braking. While public health awareness and legal restrictions can assist in educating and discouraging people from drunk & drive, a more fool-proof method is not available in the market for commercial vehicles. Currently, a low cost, fail-safe onboard alcohol detection, and vehicle safety system is the need of the hour. This paper deals with the design & development of a low cost active onboard breath alcohol detection system and it’s on vehicle validation. Further, it explains the type of alcohol detection sensor used, controller design, logic programming and system packaging. An accurate, precise and contactless alcohol detection system and advanced safety features are the key highlights. The system has been validated on the vehicle, to check the response time & alcohol detection accuracy of the sensor, the preciseness of sensor location and safety features. Safety feature include SMS & voice call based alerts, sharing of vehicle geographical location and audio warnings inside the cabin and vehicle control features such as vehicle engine auto cut off in a stationary condition for disabling vehicle cranking and in case of moving vehicle gradually reducing engine torque to stop the vehicle. Good alcohol detection accuracy and system response time has been demonstrated in the validation of the drunk subjects.

Objective Method to Quantify Ecological Toxicity between Friction Materials2017-01-24959/17/2017
California and Washington recently passed legislation to limit certain constituents in brake pad friction materials. As part of the California (CA) legislation enacted in 2010, brake pad manufacturers need to perform an alternative assessment to identify potentially safer environmental and toxicological choices for future friction material production. Copper, chromium VI-salts, lead, cadmium, mercury, and other compounds have been identified as potentially unsafe to the environment. This paper contains the methodology behind an objective and comprehensive alternative assessment to quantify the ecological impact of friction materials. Utilizing raw material specific Chemical Abstracts Service (CAS) numbers and their associated toxicological reference values (TRVs), this newly defined method estimates the total toxicological impact of finished friction materials on both the environment and on a human carcinogenic level to allow the manufacturer to screen greener alternatives. Utilizing chemical specific TRVs such as the lethal concentration 50% (LC50), median effective concentration 50% (EC50), and the median effective reproductive concentration 50% (ErC50), this method quantifies ecological impact characteristics of brake pad friction material. In the same regard, the carcinogenic properties of each chemical are evaluated, placed into groupings based on their carcinogenic potential as evaluated by the International Agency for Research on Cancer (IARC) and are utilized to generate comparative carcinogenic ratings. The methodology is best utilized as a relative comparison between multiple uncompressed friction formulations in order to create greener friction material for the future.

An Efficient Test Methodology for Combustion Engine Testing: Methods for Increasing Measurement Quality and Validity at the Engine Test Bench2017-01-06043/28/2017
Improving fuel efficiency while meeting relevant emission limits set by emissions legislation is among the main objectives of engine development. Simultaneously the development costs and development time have to be steadily reduced. For these reasons, the high demands in terms of quality and validity of measurements at the engine test bench are continuously rising. This paper will present a new methodology for efficient testing of an industrial combustion engine in order to improve the process of decision making for combustion-relevant component setups. The methodology includes various modules for increasing measurement quality and validity. Modules like stationary point detection to determine steady state engine behavior, signal quality checks to monitor the signal quality of chosen measurement signals and plausibility checks to evaluate physical relations between several measurement signals ensure a high measurement quality over all measurements. For increasing measurement validity, engine setting parameters are permanently monitored to ensure exact and consistent engine adjustments according to the test plan. Furthermore, embedded 0D engine simulations are used to correct undesired setting parameter deviations in order to create a consistent data base used for model-based optimization (DoE) and combustion-relevant component decisions. The methodology was verified by a measurement campaign carried out at an industrial engine. The new methodology is reducing potential incorrect measurements that have to be repeated. In addition, it ensures that only valid measurements are taken for model-based techniques (DoE) that have been 0D-corrected if necessary. Test bench time can be shortened, leading to a reduction in and better utilization of development costs as well.

Technology Evaluation for Two Wheeler Based Personal Mobility in Emerging Markets beyond 20202016-32-007411/8/2016
Personal mobility is evolving in the emerging markets, where the primary need for transportation is met with two wheelers. This reflects on the annual production volumes, which is forecasted to reach 160 million units by 2021[1]. Around 28% of this volume belong to electric two wheelers from China and the remaining are predominantly Internal Combustion Engines (ICE). With the regulators across the globe planning to enforce stricter emission norms in order to improve the air quality and owing to similar demand from the end customers, there is a need for technology to evolve towards harnessing the best energy efficiency using multiple technologies/architectures. However, considering that the majority of two wheelers are used by a population which is cost sensitive, it is imperative that efficient topologies need to be made available at affordable costs. The authors attempt to decipher this need for personal mobility coupled with the stringent regulations. This includes an effort to understand access to technology, legislation, rapid urbanization, infrastructure and city-congestion. The approach with this framework includes a split-of-losses analysis on the ICE and evaluating topologies of the vehicle system keeping in view the above constraints. The analysis indicates, that the hybrid electric powertrain could be an ideal fit for the next decade considering the ease of implementation and the potential success factors independent of government policies and intervention.

NOx-Conversion and Activation Temperature of a SCR-Catalyst Whilst Using a Novel Biomimetic Flash-Boiling AdBlue Injector on a LD Engine2016-01-221210/17/2016
Yearly 3.3 million premature deaths occur worldwide due to air pollution and NOx pollution counts for nearly one seventh of those [1]. This makes exhaust after-treatment a very important research and has caused the permitted emission levels for NOx to decrease to very low levels, for EURO 6 only 0.4 g/kWh. Recently new legislation on ammonia slip with a limit of 10 ppm NH3 has been added [2], which makes the SCR-technology more challenging. This technology injects small droplets of an aqueous Urea solution into the stream of exhaust gases and through a catalytic reaction within the SCR-catalyst, NOx is converted into Nitrogen and Water. To enable the catalytic reaction the water content in the Urea solution needs to be evaporated and the ammonia molecules need to have sufficient time to mix with the gases prior to the catalyst. The μMist® platform technology, inspired by nature, uses heat in order to increase the fluid temperature above the required saturation temperature within its constant volume chamber. When the outlet valve is opened the liquid breaks up into small droplets which eject and mix with the gases. This paper presents an investigation on how these heated droplets with SMD around 20μm affect the catalytic conversion and achieve high conversion whilst the ammonia slip is kept to a minimum for a few different mass flows. Injected pre-heated small droplets shows over 95 % catalytic conversion of NOx at exhaust temperatures around 200°C. During continuous operation at catalyst temperatures around 350°C - 370°C several test points reaching from 0.7 kg/h to 1.1 kg/h of AdBlue mass flow, achieved EURO VI legislation at the selected experimental conditions, not included in the WHSC (World Harmonized Steady-State Cycle), for both NOx and ammonia with higher than 98 % conversion efficiency.

A Droplet Size Investigation and Comparison Using a Novel Biomimetic Flash-Boiling Injector for AdBlue Injections2016-01-221110/17/2016
Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legislation has been reduced from 8 g/kWh (Euro I) down to 0.4 g/kWh (Euro VI) and recently new legislation for ammonia slip which increase the challenge of exhaust aftertreatment with a SCR system. In order to achieve a good NOx conversion together with a low slip of ammonia, small droplets of Urea solution needs to be injected which can be rapidly evaporated and mixed into the flow of exhaust gases. In most of today's solutions this process is enhanced with flow restricting mixers or longer path lengths but if these can be removed and shortened the flow losses can be reduced, leading to higher efficiency and lower fuel consumption as well as a more compact exhaust system. The μMist® injector, inspired by nature, takes the concept from the Bombardier beetle which induces flash-boiling in its effective defence mechanism by spraying a plume of hot poisonous fine droplets with great accuracy towards an attacker [3]. By heating up the fluid in a constant volume chamber above the saturation temperature and induce flash evaporation by opening the nozzle, the liquid breaks up into fine droplets which flow out into the target environment. This paper presents a study comparing the different effects of spray behaviour at different ratios between the saturation pressure and the target pressure. In this study the target pressure is atmospheric. The aim for the study is to gain a better understanding of the droplet sizes and the injector flow rates for different pressures and also present a limited benchmarking study of current market leading AdBlue injectors. Current testing has shown that this novel injector has the ability to produce 33% smaller droplets in SMD and 87% reduction in DV50.

New Developments of an On-Vehicle Brake Pad Waste Collection System2016-01-19499/18/2016
The design of a braking system involves a delicate balance between the friction pair, the disc and pad, where the pad is a complex blend of constituents to provide predictable characteristics, typically, a known and consistent friction level. In its base form the brake has to absorb the vehicle kinetic energy by converting it into heat. This heat absorption by the friction pair can result in chemical and physical interactions with the release of debris about which we know little. Other than environmental concerns, brake dust causes unnecessary problems with wear, thermal gradients (hot banding) and NVH. This paper is concerned with the removal and collection of brake debris from the friction interface - the debris being regarded as solids and airborne particles, the latter less than 10μm in size. The test procedure consisted of a Burnish program followed by 8 different drive cycles. The overall effects of debris removal is then reported for each test. It will be shown that, by careful design of air circulation within a collection system, over 92% of dust generated may be removed and collected. It will also be shown that debris collection results in reduced rotor and pad wear and that the brake temperatures during the braking event are not significantly affected. The impact on brake cooling and brake operating temperatures during a customer usage-based braking schedule are under study. The implementation of providing a solution “at source” may provide the automotive industry with a system to meet current U.S. legislative requirements. It will also help to satisfy future costly global legislation. In addition the module will serve as a “real life” mobile laboratory where the OEMs may gather data from the filters to gain a greater understanding of the characteristics of the debris generated during braking - saving time and money on research. This is the first paper in a series which introduces the benefits of using the on-vehicle CBPModular brake wear debris collection system.

Overview on ANVC Systems and the Future with Smart Embedded Solutions2015-01-22156/15/2015
How to decrease noise and vibration exposure has been of interest for many years. Empirical data have indicated that too high dose values can create multiple problems to a human body - often severe. Some years back, the European Machinery Directive has increased the responsibility for manufacturers and employers to make sure limits are complying with legislation. Classical technology often consists of passive solutions aiming at trying to cut back on noise and vibration levels. For low frequency, these methods are often lacking the needed performance especially if weight should be considered at the same time. A smart combination of passive and active techniques can make a real difference. Today, with possibilities for low cost and embedded electronics and the rapid development of new actuators, a vast range of applications are possible for this combined combat approach, with a financial advantage as well. Today, multiple products also utilize embedded “electronic muscles,” able to counteract harmful sound and vibration in real-time - featuring advanced control systems. All this then becomes an invisible function in the vehicle, machine or tool. The launch of such systems and successful acceptance often requires international compliance with applicable standards. New sensor concepts and approaches in combination with consumer and automotive wireless and network solutions are often key ingredients for success. It is impossible to fully grasp how this smart and embedded technology can revolutionize the sound and vibration business and open new business segments. This paper will outline these new markets and applications and give some examples from a number of applications.

City Readiness System Assessment of Electric Vehicle Adoption in China2015-01-04694/14/2015
The Chinese government initiated the “Ten Cities, Thousand Vehicles” program for electric vehicles from the year of 2009 to 2012. The demonstration results indicate that an integral city readiness system is required in the promotion of electric vehicles, including the government policies, charging infrastructure, after-sales service, business models and consumer awareness. Through the analysis of related literature and summary reports from 25 demonstration cities, a partial least squares (PLS) path model with 5 major factors and 13 observation indicators was developed to assess the city readiness of electric vehicle adoption. The 5 factors consist of government policies and investment, charging infrastructure construction and operation, business models and maintenance service system, consumer awareness education, operation scope and environmental benefits. Based on the PLS results, 25 cities are classified into 6 groups with the clustering analysis model. The assessment results show that Shenzhen, Beijing, Hefei, Shanghai, Hangzhou are the 5 cities which perform better in the city readiness assessment. Purchasing subsidies, quantity of electric vehicles per resident, quantity of cumulative charging times per vehicle, total infrastructure investment per resident, quantity of charging piles per vehicle, quantity of cumulative electricity per vehicle and quantity of operators are the 6 biggest indicators impacting on the level of city readiness system. To promote the electric vehicle commercialization, the key issues of improving the charging network construction, developing reasonable charging and service price and raising consumer awareness need to be solved.

A New and Effective Approach for Knowledge Sharing among Indian Automotive Industry2015-26-00731/14/2015
Access to Knowledge resources around the world demands special skills and calls for judicious investments. Networking is an effective tool and building networks through consortia approach is dire need of the hour. Although this approach has been used in academia, its application in industry, especially among corporate entities, is rare. This paper describes in brief an optimised way to access databases, subscriptions & memberships of different technical societies from global platforms for research & progress of Indian automotive industry. It is imperative for Indian automotive industry to enhance and strengthen its knowledge resource base, particularly in product development and manufacturing domains. This will enable the industry to achieve its mission -“AMP-2016” of becoming a hub for global auto industry. Instead of “compete and grow,” an approach of “collaborate and grow” is thought of. It is proposed to have a knowledge-centric Initiative for Indian Automotive Industry namely The Knowledge Consortium of Indian Automotive Industries (KCIAI) led by SIAM. It will be a platform for dissemination of knowledge to facilitate Indian Automotive Industry for its product development and manufacturing. The KCIAI will be a unique model for Indian Automotive Industry, at par with other societal models like CeRA, CSIR, DAE, DELNET, DRDO, FORSA, INFLIBNET, and INDEST in India for Knowledge dissemination. The KCIAI need to drive DSIR recognized in-house R&D establishments and testing institutes pertaining to Indian Auto Industry under the direction of SIAM. This can be further deployed in ACMA, and TMA & ATMA in next phases. This unique and frugal approach to knowledge sharing is inspired after internalization of SAE papers published so far in various SAE conferences since 1978 in USA.

A Methodology for the Derivation of Movement-and Load Spectra for Energy-Efficiency Test Cycles of Heavy Equipment Vehicles2014-01-23579/30/2014
As a result of the Kyoto Protocol [1], the European Union's legislation demands higher saving rates for the total energy consumption of technical equipment. Heavy Equipment, such as construction- and agricultural machines, contributes over 80% of the total off-road diesel fuel consumption in Germany per annum. It is therefore necessary to provide helpful solutions in order to reach this ambitious aim. The German Federal Ministry of Education and Research cooperates with machine manufacturers, component suppliers and research institutes in the area of heavy equipment. Under the project name TEAM [2] a three year project has been started, which is focused on the development and integration of new propulsion and steering systems for heavy equipment. One task within the project is finding an appropriate way of evaluating the energy efficiency of the enhanced machines, after the powertrain modifications have been applied to it. The wide range of applicability, as well as the existence of one or more work functions, require a special approach for evaluating the energy efficiency of this category of vehicles. Therefore, a methodology was developed, which provides a uniform way to evaluate the energy efficiency of heavy equipment. This methodology is subdivided in a workflow of three consecutive sections. The first section, which leads to a derivation of representative movement- and load spectra is described in this article. The concept of the methodology is valid for all types of examined vehicles. Being funded by the German Federal Ministry of Education and Research, the motivation for this resulting methodology is to remove the gap of missing efficiency evaluation practice for heavy equipment for European Union legislation processes in the coming years.

Development of Lens Condition Diagnosis for Lane Departure Warning by Using Outside Camera2014-01-01674/1/2014
Driver safety continues to be improved by advances in active safety technologies. One important example is Lane Departure Warning (LDW). European regulators soon will require LDW in big cars to reduce traffic accidents and New Car Assessment Programs in various countries will include LDW in a few years. Our focus is on rear cameras as sensing devices to recognize lane markers. Rear cameras are the most prevalent cameras for outside monitoring, and new Kids and Cars legislation will make them obligatory in the United States from 2014. As an affordable sensing system, we envision a rear camera which will function both as a rear-view monitoring device for drivers and as an LDW sensing device. However, there is a great difficulty involved in using the rear camera: water-droplets and dirt are directly attached to the lens surface, creating bad lens condition. The purpose of this study is to improve the durability of lane recognition systems when water-droplets and dirt are deposited on the lens surface. First, we developed various diagnostic logics under various lens conditions. We then analyzed the results of various diagnosis and expressed the lens conditions by using two evaluation axes. After that, we improve the durability of the lane recognition system including a judgment function that determines whether to stop the LDW system under heavy dirt and water-droplets. We conducted driving tests and captured evaluation movies in the United States, Europe, and Japan. We evaluated the lane recognition rate for a total of 8 hours of evaluation movies under various weather conditions. We achieved a lane recognition rate of 95% and improved the durability of the lane recognition system.

Vehicle-Based Driver Interlocks: After 50 Years of Research, can we now Design an On-Board, Real-Time System to Detect Abnormal Driving Behavior?2014-01-02754/1/2014
In its simplest form, an interlock is a device, installed in a vehicle, that monitors the safety of the vehicle and its occupants, decides whether the vehicle or its occupants are in danger and warns the occupants, or influences the operation of the vehicle. The first interlocks were designed to detect alcohol intoxicated drivers. Three categories of performance interlocks can be identified: Type I interlocks sense physiological parameters of the driver (e.g. alcohol content of alveolar air) determine the driver's level of intoxication and, after comparing this level with a criterion level (e.g. the legal limit for driving), decide whether or not the vehicle should be operated. Type II interlocks measure the behaviour of the driver with cockpit-mounted equipment (e.g. eye movement monitors) or on driving-related tasks and compare this behaviour with established norms. Types III interlocks measure driving performance directly and compare the measured values with performance norms. The purpose of this paper is to review the research, conducted on driver performance interlocks over the past 50 years, specifically on Type III devices. In addition, the review looks at recent advances in intelligent vehicle technologies that could lead to the development of a Type III device. Finally, a way forward is proposed for the development of an on-board system to detect and respond to abnormal driving behavior.

An Approach to Develop Energy Efficient Operation Strategies and Derivation of Requirements for Vehicle Subsystems Using the Vehicle Air Conditioning System as an Example2013-01-05684/8/2013
Rising oil prices and increasing strict emission legislation force vehicle manufacturers to reduce fuel consumption of future vehicles. In order to meet this target, the process of converting fuel into useable energy and the use of this energy by the different energy-consuming vehicle's subsystems have to be examined. Vehicles' subsystems consist of energy-supplying, energy-consuming, and in some cases energy-storing components. Due to the high complexity of these systems and their interaction, optimization of their energy efficiency is a challenging task. By introducing individual operational strategies for each subsystem, it is possible to increase the energy efficiency for a specific function. To further improve the vehicle's overall energy efficiency, holistic control strategies are introduced that distribute the energy between the subsystems intelligently. To exhaust the whole potential of a holistic control a certain number of degrees of freedom between energy supply and consumption are necessary. This is particularly relevant for subsystems that consume large amounts of energy. To solve this problem, a new methodical approach is being presented. This approach is applicable to every energy-consuming subsystem and describes requirements and advantages of unified system architectures as well as a procedure to construct energy-efficient operational strategies, with the air conditioning system being used as an example. To support the methodical approach, a simulation model has been created. The model describes the energy flows among energy suppliers, energy reservoirs, and energy consumers of given subsystems and in particular of the air conditioning system, depending on the vehicle's environment and a selected driving cycle.

On-Site Checks of the Particle Number Measurement Systems with Polydisperse Aerosol2012-01-08734/16/2012
Since 2011 a particle number (PN) limit was introduced in the European light-duty diesel vehicles legislation. The PN measurement systems consist of i) a hot diluter and an evaporation tube at 300-400°C for the removal of the volatiles (Volatile Particle Remover, VPR) and ii) a particle number counter (PNC) with a 50% cut-point (cut-off) at 23 nm. The PN measurement systems are calibrated and validated annually with monodisperse aerosol: The VPR for the particle concentration reduction factor (PCRF) and the PNC for the linearity and the cut-off size. However, there are concerns that the PN measurement systems can drift significantly over this period of time, raising concerns regarding the validity of the previous measurements, especially if the yearly validation fails. In this paper we describe some relatively fast and simple on-site checks for the evaluation of the proper operation of the PN measurement systems with polydisperse aerosol, thus avoiding the need of electrostatic classifiers and radioactive sources. The necessary equipment are i) a particle generator that produces polydisperse aerosol with thermally stable particles of known count median diameter (CMD) at different concentrations and ii) a calibrated reference PNC with a nominal 50% cut-point at 23 nm and linear response at the whole measurement range. The recommended checks for the PNC under evaluation (test PNC) are: 1) Linearity check: The test PNC measures in parallel with the reference PNC polydisperse aerosol with CMD ≻50 nm at different concentrations. The differences, similarly with the legislation requirements, have to be within 10%. 2) Cut-off size check: Only the test PNC measures polydisperse aerosol with CMD=10 nm. The concentration measured by the test PNC should be ≺100 p/cm₃. If a PNC with a 50% cut-point at 10 nm or lower is available another possibility is to produce an aerosol with CMD=23 nm and compare the ratio of the test PNC to the reference PNC, which should be within the legislation requirements (0.38-0.62). The recommended checks for the VPR are: 3) PCRF check of the VPR: The reference PNC measures upstream and downstream of the VPR (set to a low PCRF ≺1000) thermally stable aerosol with CMD around 50 nm. Similarly with the legislation requirements, the upstream-to-downstream ratio has to be within 10% of the PCRF setting. 4) Relative check of the rest PCRFs: The reference PNC measures downstream of the VPR and different PCRFs are measured. The PCRF corrected emissions for each PCRF measured should be within 10% of the previously checked low PCRF. Theoretical calculations showed that these checks can identify a drift of the VPR or PNC and experimental data confirmed that they work in practice.

Integrating In-Wheel Motors into Vehicles - Real-World Experiences2012-01-10374/16/2012
Compact direct drive in-wheel motors with integrated inverters, control and brakes offer a number of distinct advantages compared to conventional electric drive systems. The most obvious being that the drivetrain is now packaged within the wheel freeing up space elsewhere, in addition many driveline components and their associated losses are eliminated and the vehicle efficiency, response and handling can be improved. In new vehicle applications this allows complete freedom for designers to optimize the vehicle layout, have more usable space inside the vehicle body and enables revolutionary vehicle concepts (which will become more important as road space becomes scarce and taxation measures migrate towards vehicle size). In retrofit applications the compact package allows an electric drive to be added to any existing vehicle without requiring any significant disruption to the vehicle platform to keep integration costs down. This represents an opportunity for OEM's to hybridize their existing vehicle portfolio in order to address more stringent fleet-average emissions legislation. Protean has retrofitted its Protean Drive™ in-wheel motors to a variety of different vehicles in both pure EV and hybrid configurations and has collated its findings over three years of track and road testing. This paper will distil the practical experience gained from these vehicle programs and illustrate some of the challenges and solutions associated with in-wheel motor integration. In doing so the paper deals with many of the key vehicle level topics, such as the CAN interface, vehicle control strategy, and brake integration.

Data ManagementGEIA859A (Historical)4/1/2012
Data is information (e.g., concepts, thoughts, and opinions) that have been recorded in a form that is convenient to move or process. Data may represent tables of values of various types (numbers, characters, and so on). Data can also take more complex forms such as engineering drawings and other documents, software, pictures, maps, sound, and animation. For the purpose of this standard, Table 1 lists three broad types of data, indicates how each is used, and provides examples of each. Data management, from the perspective of this standard, consists of the disciplined processes and systems that plan for, acquire, and provide stewardship for product and product-related business data, consistent with requirements, throughout the product and data life cycles. Thus, this standard primarily addresses product data and the business data required for collaboration from the team level or extended through the trading partner level during product acquisition and sustainment. It is recognized, however, that the principles described in this standard also have broader application to business data and operational data generally. It is also recognized that the data addressed by this standard is subject to data administration, metadata management, records management, and other processes applied at the enterprise level, and that these principles must be applied in that enterprise context. Data has many purposes, including stating requirements, providing proof of achievement, and establishing a basis for long-term product support. Deliverable data (customer-accessible information) represents only a small fraction of the project data. In general, a vast amount of design, development, fabrication, and manufacturing data remains the intellectual property of the developer/producer unless ownership has been transferred via contractual or other agreement. For example, the National Defense Authorization Act for Fiscal Year 2007 - Section 8changed the assumption of ownership of rights in technical data in defense acquisition programs. Further, the value of data is not limited to its use in support of a specific product: data may have a life cycle longer than that of the product it describes. For instance, data from previous projects forms part of the foundation for new product and process design. Data also supports the enterprise in process redesign and quality. Thus data is essential to competitive position. An enterprise’s data—if not properly safeguarded—can also be misused by a competitor to the competitor’s advantage. For these reasons, data is an integral part of an enterprise’s intellectual assets and overall enterprise knowledge.

The Technical Efficiency of Chennai Auto Industry Cluster2011-28-010010/6/2011
The Chennai is an one of Automotive hub of India due to it's Automotive Industry presence producing over 40% of the India's Vehicle and Components. During 2001-02, the Automotive Component Industries(ACI) in Ambattur Industrial Estate, Chennai has faced problems on infrastructure(Approach Road, Storm water drainage system, Sewerage System, Sewage treatment plant, Solid Waste Management, Landscaping, Street Lighting and Logistics/ Parking), technology, procurement, production and marketing. In the year 2004-05 under the Cluster Development Approach (CDA), they formed Auto Cluster (AC) got grant under Industrial Infrastructure Upgradation Scheme from Government of India under Public Private Partnership Concept and implemented UNIDO-AIEMA Auto Cluster Supplier Development Programme under Consolidated Project for SME development in India. Due to this the infrastructure, technology, procurement, production and marketing interrelationships taken place among ACI. The objective is to find the technical efficiency of auto cluster before (2001-02) and after the CDA (2008-09). The methodology adopted is collection of primary data from ACI and analyzing using Data Envelopment Analysis (DEA) of Charnes-Cooper-Rhodes (CCR) Model. The Correlation Coefficient Analysis reveals that there is significant increase in correlation coefficient and the Regression Analysis informs that for one percent increase in employment and net worth the gross output increases significantly after the CDA. The DEA gives the technical efficiency of ACI by taking employment, net worth as input variable and gross output as output variable. From the technical score and ranking of auto component manufactures, it is found that there is significant increase in technical efficiency of ACI after the CDA when compared to before CDA. The slack variables obtained clearly reveals the excess employment and net worth and no shortage of gross output. Government policy on CDA by intervention in interrelationships not only benefited Chennai Auto Cluster in general but also Chennai Auto Components Industries in particular.

Improving Program Management Through Web-Enabled “PLM for All”2011-01-05204/12/2011
Today's engineers must meet program management demands within the context of the challenges facing the industry as a whole. Resource scarcity, both people and capital, is forcing the automotive industry to optimize the deployment and consumption of enterprise resources. As globally dispersed project teams become more commonplace, efficient and effective communication across geographies is critical. Market segmentation and technology are influencing how well manufacturers deliver products within performance and timing guidelines. Future success means providing global engineering teams with state- of- the- art tools and processes to unify disparate business groups in a virtual workspace -24/7. The solution to this is Product Lifecycle Management (PLM), a strategic business approach that supports collaborative creation across the enterprise and all stakeholders. PLM solutions link information from different authoring tools and others systems to the developing product configuration. However, for real time collaboration, the approach must be accomplished through PLM 2.0, “an ONLINE ENVIRONMENT FOR ALL.” Through implementation of a unique architecture platform, PLM 2.0 is a reality that creates an online environment that allows stakeholders to work concurrently in real time via a simple Web connection accessing the latest information regardless of geographic location. Collaborative online creation gets a boost from enhanced 3D applications that deliver an intuitive interface, enabling users to work in visual context and experience how products react to changes. By eliminating language barriers, 3D changes occur with no misinterpretations - 24/7, regardless of location. Some of the benefits obtained from this strategy include the leveraging of intellectual assets throughout the entire product lifecycle, the creation of a virtual, global value chain without time, distance or organizational boundaries, and enhancement of the ability to innovate and improve products. All of this leading toward better vehicles delivered in a more timely and cost-effective manner.

Sauer-Danfoss - Managing tomorrow's big challenges with today's limited resources10OFHD0803_108/3/2010
Executive Viewpoints-Vehicle Development Insights from Industry: Driving Factors for Future Innovation. While dealing with the unpleasant results of the last year, engineering teams also undoubtedly looked toward the future-most specifically, at new regulations that are in place or on the near horizon. New EU functional safety standards, the advent of Tier 4 in the U.S. and Stage IV in Europe, and the continuing end-user demands of a better operator experience are all compelling events that must be addressed. On top of (or perhaps in spite of) these new regulations, customers demand these machines more quickly than ever, and OEM senior management teams require machines that differentiate themselves in the market. Even through these tough times, Sauer-Danfoss has been working as part of our customers' development teams to take on these big challenges. Despite the downturn, our test lab and research work has continued. We've taken a vehicle-by-vehicle approach to expand our applications and vehicle systems knowledge, tackling these new regulations while maintaining efficiency and total vehicle performance. Our goal is to deliver system solutions and flexible products that greatly reduce the engineering effort required by our customers to meet these challenges. We are doing this by designing products that simplify system integration, validating standard system design solutions in our test labs, and developing standardized control software solutions that allow engineers to improve both systems performance and operator experience.

High Performance Cooling and EGR Systems CMN-1009 test1242008-01-11994/13/2009
In relation to further tightening of the emissions legislation for on-road heavy duty Diesel engines, the future potential of cooled exhaust gas recirculation (EGR) as a result of developments in the cooling systems of such engines has been evaluated. Four basic engine concepts were investigated: an engine with SCR exhaust gas aftertreatment for control of the nitrogen oxides (NOx), an engine with cooled EGR and particulate (PM) filtration, an engine with low pressure EGR and PM filtration and an engine with two stage low temperature cooled EGR also with a particulate filter. A 10.5 litre engine was calibrated and tested under conditions representative for each concept, such that 1.7 g/kWh (1.3 g/bhp-hr) NOx could be achieved over the ESC and ETC. This corresponds to emissions 15% below the Euro 5 legislation level. It was found, as a consequence of the two stage low temperature EGR cooling, that not only could the fuel economy of the engine be improved compared to that with conventional EGR cooling but that this economy was similar to that of the SCR engine concept (when the urea solution consumption was taken into account). The required cooling performance was achieved via optimisation of the cooling system without an increase in the fan power requirement. It was also found that the engine with two stage low temperature cooled EGR could achieve NOx emissions significantly less than 1 g/kWh (0.7 g/bhp-hr) over the legislated test cycles with consistent fuel economy.

Building Competencies for Product Development in Brazilian Subsidiaries of MNCs of the Automotive Industry2008-36-030810/7/2008
Product Development (PD) carried out in subsidiaries of multinational corporations (MNCs) located in countries with emerging markets provides advances in factors of production, creates high-quality jobs, increases specialisation of the workforce, and it is favourable to a strategic insertion of the host country in the international division of labour. Most importantly, it enhances the overall productivity and competitiveness of the MNC as a whole, because it shrinks the time-to-market, dropping development costs and releasing the pipeline pressure from traditional designing centres of the company. This paper analyses the overall conditions of Product Development competence building at subsidiaries of automotive companies located in Brazil, and puts forward an explanatory model of this competence building process. The study was held at two Brazilian subsidiaries that had effectively developed new products - General Motors do Brasil and Volkswagen do Brasil - with the use of Grounded Theory methodology. The model shows that competence building is caused by objective and subjective factors. Among the former are the specific conditions of the Brazilian market, competitive factors of the automotive industry in the country, and government tax policies; among the latter are specific training promoted by the parent company, standardisation of engineering procedures with the use of high tech development resources, and expatriation of executives. Implications for theory and management practices are discussed.
