Comprehensive Evaluation of Logging Frameworks for Future Vehicle Diagnostics2023-01-122306/26/2023
More and more applications (apps) are entering vehicles. Customers would like to have in-car apps in their infotainment system, which they already use regularly on their smartphones. Other apps with new functionalities also inspire vehicle customers, but only as long as the customer can utilize them. To ensure customer satisfaction, it is important that these apps work and that failures are found and corrected as quickly as possible. Therefore, in-car apps also implicate requirements for future vehicle diagnostics. This is because current vehicle diagnostic methods are not designed for handling dynamic software failures of apps. Consequently, new diagnostic methods are needed to support the diagnosis of in-car apps. Log data is a central building block in software systems for system health management or troubleshooting. However, there are different types of log data and log environment setups depending on the underlying system or software platform. Depending on that, the creation of

Direct Alert to In-Vehicle Infotainment (DAIVI)2022-01-026203/29/2022
Nowadays, the mobile phone features are widely used by drivers to get the notifications and alerts on the head unit. However, there are no available products in the market to get important notifications in Head units without the use of mobile phones. There are many important notifications that are critical for a user when he is away from home. Some of them are alerts from home security systems, smoke and gas detection alarms etc. Most of the existing systems push alerts to customer mobile phones. In this paper, the authors propose a concept to direct the alerts to In-Vehicle Infotainment systems. Proposed here is a new approach, Direct Alert to In-Vehicle Infotainment (DAIVI), in which the infotainment head unit will be able to get the notification or alerts without using a mobile phone. The DAIVI complements the existing systems of alerts to the user by using in-vehicle infotainment for alerting on the critical issue.

Practical Uses for Road Noise Cancellation2021-01-101808/31/2021
Today’s automotive customers have come to expect luxury and electric vehicles to be quiet and refined pieces of machinery. As customers have come to expect powertrain cancellation in most vehicles today, they are also increasingly looking for a reduction in road noise to improve their overall perception of luxury and electric vehicles. While the field of noise cancellation is ever expanding, several auto makers are exploring the possibility of introducing a real time Road Noise Cancellation (RNC) system to meet these customer expectations. An RNC system can be integrated into the vehicle infotainment system and be utilized to either noticeably reduce or shape the vehicle noise floor. This paper will look at the current traditional Noise and Vibration (N&V) methods of reducing road noise and then also the benefits associated with actively controlling the amount of road noise using an RNC system.

Intelligent Voice Activated Drone(s) for in-Vehicle Services and Real-Time Predictions2021-01-006304/06/2021
Today, commercially available drones have limited use-cases in the rapidly evolving community. However, with advances in drone and software technology, it is possible to utilize these aerial machines to solve problems in a variety of industries such as mining, medical, construction, and law enforcement. For example, in order to reduce time of investigation, Indiana State Police are currently utilizing ad-hoc commercial drones to reconstruct crash scenes for insurance and legal purposes. In this paper, we illustrate how to effectively integrate drones for in-vehicle services and real-time prediction for automotive applications. In order to accomplish this, we first integrate simpler controls such as voice-commands to control the drone from the vehicle. Next, we build smart prediction software that monitors vehicle behavior and reacts in real-time to collisions. Furthermore, we employ object recognition techniques through In-Vehicle Infotainment (IVI) systems to identify the surroundings

Model-Based Design of Service-Oriented Architectures for Reliable Dynamic Reconfiguration2020-01-136404/14/2020
Service-oriented architectures (SOAs) are well-established solutions in the IT industry. Their use in the automotive domain is still on the way. Up to now, the automotive domain has taken advantage of service-oriented architectures only in the area of infotainment and not for systems with hard real-time requirements. However, applying SOA to such systems has just started but is missing suitable design and verification methodologies. In this context, we target to include the notion of model-based design to address fail-operational systems. As a result, a model-based approach for the development of fail-operational systems based on dynamic reconfiguration using a service-oriented architecture is illustrated. For the evaluation, we consider an example function of an automatically controlled braking system and analyze the reconfiguration time when the function fails. The reconfiguration time, together with the worst-case execution time (WCET), was determined by a model-based calculation

A Performance Measurement and Analysis Method for Infotainment System2020-01-134704/14/2020
The software must be verified and optimized from time to time to ensure system performance quality from the development process. Because the later you discover performance issues, the greater the cost of performance improvements, along with the extent to which they are fixed in the source code. In particular, performance problems due to poor system design should be identified and corrected as soon as possible. Also, as development progresses, source code added for new features and modified by bugs can potentially increase system resource usage or worsen responsiveness. Therefore, the development process needs to periodically measure, analyze, and improve system performance. This paper introduces the system-wide performance analyzer and explains how to use it to measure and analyze the performance of the infotainment system for performance management and improvement. Also describe the application cases that use it, finally, explain future development directions to cover the area of the

Step & Repeat: Reduce Derivative Aircraft Development Risk with Design Reuse2019-01-187109/16/2019
The complex and risky process of designing derivative aircraft, especially when it comes to electrical systems, can be a daunting task at best. There are a number of design strategies that can be employed to mitigate risk and increase the overall efficiency. Quite simply, the current methods of manual processes, design and integration approaches that were optimized from mechanical approaches, are no match for today’s complexities. One method gaining significant traction is to employ a central database serving global interface definitions for the entire design process. Automation through generative design minimizes manual intervention and repetitive work. Furthermore, detecting changes through design rule checks allows system engineers to verify their designs, capturing both inadvertent and planned changes. The ability to instantly update the design content from the new definition streamlines the change management process. Employing these technologies in a digital, connected thread

Empathy to Elevate the User Experience19AVEP09_1009/01/2019
Harman developers are striving to create human-machine interfaces oriented more towards user needs. In-car connectivity for today's cars and tomorrow's autonomous vehicles is moving product development norms beyond the traditional engineering approach. “Most products are designed from a straightforward engineering focus: It works like this. But with a user experience approach, it's about designing with empathy,” said Jason Johnson, director of user experience (UX) design at Harman. Designing with empathy essentially means that product developers strive to make decisions that align with user needs and wants. “What matters are the answers to these questions: Are users accomplishing their tasks and goals? What are they going to tell their friends about the experience? And will that feedback be positive or negative?” Johnson said.

New design for 2020 Mitsubishi Outlander Sport as brand awaits alliance's new platforms, products19AUTP06_1606/01/2019
The 2020 Mitsubishi Outlander Sport carries over with no mechanical changes compared to the 2019 model. But its new face-part of a front/rear styling redo plus new interior trims/tech for the 5-seat, 2-row SUV-signals a new start for the brand in the U.S. Having pared its product lineup to all-SUV plus the economy minded B-segment Mirage, the triple-diamond brand is saucing up its styling while it awaits a bevy of new platforms and products from its alliance with Nissan/Renault. Mitsubishi sold over 100,000 vehicles in the U.S. for the last two years running. Compared to the nearly 350,000 vehicles it sold in 2002 (or the 800K pickups Ford delivers in a year), this might not sound spectacular. But compared to the sub-54K year it had in 2009, the steady growth over the last 10 years (including a 14% jump last year in a flat-overall market) shows that life is returning to the brand.

Securing Inter-Processor Communication in Automotive ECUs2019-26-036301/09/2019
Modern cars now come with sophisticated telemetry which often involve connecting to the internet over mobile telephone networks or Wi-Fi. The telemetry or cloud functions of the car is typically handled by a Telematics Control Unit or the Infotainment System. The microcontrollers (Host Processor) powering the ECUs are very powerful and often have operating systems such as Linux or QNX to drive the large displays or perform modem functionalities. These powerful microcontrollers take several seconds to startup and does not offer hard real-time performance - both of which are critical to handle the vehicle CAN network. Hence, it is common to include a less powerful microcontroller to the ECU to perform the management of the vehicle CAN network. These smaller microcontrollers (Vehicle Processor) can startup fast and provide hard real-time performance. The Host Processor and the Vehicle Processor are connected by the Inter-Processor Communication Link (IPCL) to exchange information between

Analysis of Berla iVe Acquisitions of Vehicle Speed Data from Ford Sync Systems2018-01-144204/03/2018
Many modern automobiles’ infotainment/navigation systems store vehicle telematics and user-supplied infotainment data. This data is useful in a wide variety of analyses but is not available through traditional OEM tools. The necessity to access the infotainment module data for forensic analysis can be satisfied by utilizing the Berla iVe system. Similar to CDR/EDR technology, Berla iVe is a hardware and software tool that is used to acquire and analyze stored automotive data. However, CDR/EDR systems are generally developed in partnership with manufacturers or OEM suppliers. Berla iVe is a privately developed forensic system analogous to traditional forensic tools used to interrogate computer hard drives and smartphones. The technology is privately developed and tested. The data is then parsed using recognized forensics practices. This research was focused on assessing the accuracy of speed data recorded in certain modules and the resulting translations reported by the Berla iVe system

Development of a CAE Method for Predicting Solar Loading Impact for Electrical System Performance in an Automotive Cabin2018-01-078504/03/2018
A number of market factors such as customer demand for improved connectivity and infotainment systems, automated driver assist systems and electrification of powertrain have driven an increase in the number of electrical systems within the cabin of automotive vehicles. These systems have limited operating temperature windows, therefore markets with high ambient temperatures and solar loading represent a significant challenge due to high cabin temperatures. Traditionally climatic facilities have been used replicate the conditions seen in these markets in order to understand the performance of the electrical systems. However such facilities have a number of limitations such as fixed solar arrays, secondary radiation from the walls and substantial operating costs limiting testing to envelope tests. Therefore the requirement for CAE based approach to more accurately represent the conditions seen in the real world is clear. To this end this work presents a CAE method for predicting

Fusing all these inputs into a single image of each car, pedestrian and roadway marking takes a sophisticated architecture with hefty amounts of computing power and deterministic communications. At highway speeds, combining inputs from multiple camera views is a complex challenge by itself. But different sensor types are needed to avoid errors, so vehicle controllers must blend inputs coming from multiple sensors and multiple modalities.

Reconfigurable chip usage ramps up as ADAS advances17AUTP11_1011/01/2017
Reconfigurable processors have seen growing use in rapidly-changing infotainment systems and are expanding into advanced driver assistance systems (ADAS). The role of field-programmable gate arrays (FPGAs) and other customizable processors is expected to develop further with the emergence of autonomy, where the vagaries of artificial intelligence makes customization more important. As vehicle OEMs make software more of a differentiator, devices that make it simple to alter hardware to match changes in algorithms and software are becoming more practical. In a growing number of systems, changes in software can improve performance significantly. Sometimes, performance can be further improved by altering the programming structure.

Analysis of Vehicle Voice Recognition Performance in Response to Background Noise and Gender Based Frequency2017-01-188806/05/2017
Voice Recognition (VR) systems have become an integral part of the infotainment systems in the current automotive industry. However, its recognition rate is impacted by external factors such as vehicle cabin noise, road noise, and internal factors which are a function of the voice engine in the system itself. This paper analyzes the VR performance under the effect of two external factors, vehicle cabin noise and the speakers’ speech patterns based on gender. It also compares performance of mid-level sedans from different manufacturers.

Traditional and Electronic Solutions to Mitigate Electrified Vehicle Driveline Noises2017-01-175506/05/2017
Hybrid powertrain vehicles inherently create discontinuous sounds during operation. The discontinuous noise created from the electrical motors during transition states are undesirable since they can create tones that do not correlate with the dynamics of the vehicle. The audible level of these motor whines and discontinuous tones can be reduced via common noise abatement techniques or reducing the amount of regeneration braking. One electronic solution which does not affect mass or fuel economy is Masking Sound Enhancement (MSE). MSE is an algorithm that uses the infotainment system to mask the naturally occurring discontinuous hybrid drive unit and driveline tones. MSE enables a variety of benefits, such as more aggressive regenerative braking strategies which yield higher levels of fuel economy and results in a more pleasing interior vehicle powertrain sound. This paper will discuss the techniques and signals used to implement MSE in a hybrid powertrain equipped vehicle. MSE utilizes

New autonomous-driving module uses raw sensor data to enhance speed17AUTP05_1105/01/2017
The race to gain a foothold in the emerging autonomous vehicle market continues to attract more players. Mentor Graphics Embedded Systems Division is joining the game, introducing a system that captures raw sensor data and makes driving decisions. Mentor's new platform captures and fuses raw data from radar, lidar, vision and other sensors, then decides whether to turn, brake or take other actions. The DRS360, unveiled at the SAE WCX17 in Detroit, is aimed primarily at SAE Level 5 autonomous vehicles, though it can also be used for advanced driver assistance systems (ADAS).

TODAY'S AUTOMOBILE Supercomputer on WheelsTBMG-2666304/01/2017
With every passing year, it's getting more difficult to recognize the current crop of passenger vehicles as the descendants of Henry Ford's Model T. Those first mass-produced vehicles didn't even include a battery or starting system, relying instead on a hand-cranked engine with a magneto to provide ignition. As recently as 20 years ago, many cars were still essentially mechanical systems supplemented by hydraulic or electrical systems for handling functions like steering, ignition, lights, and audio entertainment.
CONNECTIVITY continues its advance17TOFHP04_0104/01/2017
More OEMs and Tier 1 suppliers are focusing on embedded telematic systems, hoping to displace aftermarket hardware. Fleet owners have been deploying telematic solutions for some time, but connectivity still is just beginning to move from early adopters to the mass market. Connectivity is providing more owners and operators a broad range of benefits, prompting a surge of developments by suppliers. Connections using cellular and other wireless links are transforming design plans, running the gamut from axles and infotainment systems to leveraging cloud computing. Connectivity even is beginning to impact developments at companies that traditionally focus more on mechanical designs than electronics, according to some contract designers.

Haptic feedback for gesture-control HMI17AUTP04_0404/01/2017
Mid-air gesture controls rely on sophisticated sensing to aid the human-machine interface and help keep drivers' eyes on the road. Gesture control is becoming more commonplace in many of the devices we use in our daily lives, from games consoles, swiping and pinching on mobile phones, to point-of-sale devices such as ticketing systems in train stations. The automotive segment is already adopting gesture control for infotainment systems as well as serving as a human-machine interface (HMI) for subsystems such as the sunroof, climate control and audio. BMW's latest 7 Series and 5 Series offer an HMI system that can detect four different gestures: setting the car's navigation, browsing apps and starting the audio, answering phone calls and controlling the on-board computer. Volkswagen last year announced gesture controls on its Golf and pledges to spread the technology across its model ranges. Other major OEMs have the technology in their product pipelines.

Waste Heat Recovery for Light-Duty Truck Application Using ThermoAcoustic Converter Technology2017-01-015303/28/2017
Nearly a third of the fuel energy is wasted through the exhaust of a vehicle. An efficient waste heat recovery process will undoubtedly lead to improved fuel efficiency and reduced greenhouse gas (GHG) emissions. Currently, there are multiple waste heat recovery technologies that are being investigated in the auto industry. One innovative waste heat recovery approach uses Thermoacoustic Converter (TAC) technology. Thermoacoustics is the field of physics related to the interaction of acoustic waves (sonic power) with heat flows. As in a heat engine, the TAC produces electric power where a temperature differential exists, which can be generated with engine exhaust (hot side) and coolant (cold side). Essentially, the TAC converts exhaust waste heat into electricity in two steps: 1) the exhaust waste heat is converted to acoustic energy (mechanical) and 2) the acoustic energy is converted to electrical energy. The converted electrical energy can be used to offload the alternator, supplying
