Towards AI-Driven Automated Driving Systems: Homologation perspective2026-26-0133To be published on 01/16/2026
This paper examines the challenges and opportunities in homologating AI-driven Automated Driving Systems (ADS). As AI introduces dynamic learning and adaptability to vehicles, traditional static homologation frameworks are becoming inadequate. The study analyzes existing methodologies, such as the New Assessment/Test Methodology (NATM), and how various institutions address AI incorporation into ADS certification. Key challenges identified include managing continuous learning, addressing the "black-box" nature of AI models, and ensuring robust data management. The paper proposes a harmonized roadmap for AI in ADS homologation, integrating safety standards like ISO/TR 4804 and ISO 21448 with AI-specific considerations. It emphasizes the need for explainability, robustness, transparency, and enhanced data management in certification processes. The study concludes that a unified, global approach to AI homologation is crucial, balancing innovation with safety while addressing ethical

A unified Framework for Industry 4.0 based Automotive Homologation in India2024-26-036001/16/2024
The term Industry 4.0 is well known in contemporary automotive landscape. It encompasses a smart integrated framework of IoT (Internet of Things) and industrial automation with machine learning, artificial intelligence and big data analytics to arrive at optimal solutions to running the processes in a streamlined, efficient and effective manner. Industry 4.0 has assumed critical significance in the contemporary era of people working from remote locations to operate processes in order to build products, thus ensuring business continuity. Consequently, it follows that if industry 4.0 is applied to automotive homologation activity, it will lead to better evaluation, better fidelity of testing and accurate judgement of the product under test with regards to its certification. The author hereby elucidates a unified Industry 4.0 Framework for Automotive homologation in India which is the need of the hour. This framework consists of five elements. The first is use of IoT to ensure optimal use

Since 2015, Elon Musk has been claiming that new Tesla vehicles would be capable of fully automated driving within a couple of years - with just software updates and pending regulatory approvals. Both parts of that statement were wrong. Tesla doesn't appear to be anywhere near producing vehicles capable of safe operation without human supervision. And until recently, regulations did not exist covering homologation of automated vehicles. However, with passage of a new rule covering Europe and much of Asia, AV regulations are finally starting to become a reality. In late June 2020, the United Nations Economic Commission for Europe's (UNECE) World Forum for Harmonization of Vehicle Regulations passed the first rules directly governing SAE Level 3 automated lane keeping systems. L2 systems like Tesla AutoPilot, GM Super Cruise and Ford's upcoming Active Drive Assist are becoming increasingly common. These systems nominally require the human driver to remain alert while supervising the
LEAN Techniques for Effective, Efficient and Secure Information Processing in Automotive Homologation2019-26-033501/09/2019
It is an established fact that virtual knowledge based engineering has revolutionized R & D activities by streamlining processes, ensuring productivity and accuracy. This has resulted in freeing up time for quality interpretational work and decision making for engineering the best of products. Subsequently, homologation is a mandatory requisite activity for product signoff. It certifies the quality of the product and is an important factor in giving the product an authenticity for sale in the market. Homologation entails compliance to regulations existing in form of well-established standards which elaborate systematic and detailed guidelines on conducting physical testing for automotive systems, sub-systems or components for specific vehicle types. The contemporary homologation scenario encompasses heavy usage of virtual platform tasks like data acquisition, application of heuristics from the standards, post processing, classification, test output report and type approval certificate

Engine oil Thermal Management: Oil Sump Volume Modification and Heating by Exhaust Heat During ICE Warm Up2018-01-136604/03/2018
In the perspective of fuel saving and emissions reduction, engine oil thermal management has not yet received the attention it deserves. Lubricating oil, in fact, should be the focus of a specific warmup action: the expected benefits is on friction reduction – mechanical efficiency improvement – but also on a positive interaction with the cooling fluid thermal dynamics. The lower thermal capacity of the circulating oil (with respect to the cooling fluid) and the instantaneous reduction of the viscosity due to temperature increase produces a faster engine overall efficiency benefit: this invites to focus specific actions on its thermal management in the direction of speeding up the temperature rise during a cold engine starting. Being the mechanical engine efficiency strongly influenced by the friction losses and considering the important benefits on oil viscosity due to a temperature increase, important beneficial effects should be observed on fuel consumption: unfortunately, the big

Experimental Analysis of Fuel and Injector Body Temperature Effect on the Hydraulic Behavior of Latest Generation Common Rail Injection Systems2018-01-028204/03/2018
The present paper describes the effect of thermal conditions on the hydraulic behavior of Diesel common rail injectors, with a particular focus on low temperatures for fuel and injector body. The actual injection system thermal state can significantly influence both the injected quantity and the injection shape, requiring proper amendments to the base engine calibration in order to preserve the combustion efficiency and pollutant emissions levels. In particular, the introduction of the RDE (Real Driving Emission) test cycle widens the effective ambient temperature range for the homologation cycle, this way stressing the importance of the thermal effects analysis. An experimental test bench was developed in order to characterize the injector in an engine-like configuration, i.e. fuel pump, piping, common rail, pressure control system and injectors. One of the injectors is used for the measurement of injection rate time profile by means of a Zeuch method-based injection analyzer, mean

Increasing Modern Spark Ignition Engine Efficiency: A Comprehension Study of High CR and Atkinson Cycle2016-01-217210/17/2016
Increasing global efficiency of direct injection spark ignition (DISI) engine is nowadays one of the main concerns in automotive research. A conventional way to reduce DISI engine fuel consumption is through downsizing. This approach is well suited to the current homologation cycle as NEDC, but has the drawback to induce over-consumptions in customer real driving usage. Moreover, the driving cycles dedicated to EURO 6d and future regulations will evolve towards higher load operating conditions with higher particulate emissions. Therefore, efficiency of current DISI has to be strongly increased, for homologation cycle and real driving conditions. This implies to deeply understand and improve injection, mixing and flame propagation processes. This work proposes an alternative way to improve the thermodynamic efficiency of the combustion system, by coupling an increase of Compression Ratio (CR) with high levels of Exhaust Gas Recirculation (EGR) and the setup of Miller/Atkinson cycle at

Mexico City Traffic and Los Angeles City Traffic Testing: An Approach to Test Route Development for Results Homologation2012-01-180809/17/2012
Vehicle testing on public roads is used by the automotive community in different locations to evaluate the noise characteristics of brake systems under typical customer usage conditions. These tests are generally carried out on different locations and show results with questionable compatibility as has been concluded on several investigations over the last years [1]. Global projects on the other hand mandate to have tests that can represent vehicle usage in several types of environments in order to have reliable indicators of performance on different conditions. This paper suggests a method to characterize roads on different sites and modify the route to match a specific target.

Simulation-based Certification of ESC Systems for Passenger Vehicles in Europe2012-01-023504/16/2012
In today's automotive climate, the tendency of an increasing number of vehicle model variants offered is coming to a head with the growing demands for safer vehicles. New legislation now ensures that the safety improvement by the fitment of stability control systems is certified for each new vehicle. Beginning year 2012, all new cars to be sold in the European Union have to be equipped with ESC, and as means to test performance, a new supplement to ECE R13 requires that the Sine-with-Dwell test be passed. As a result, OEMs have to handle the task of demonstrating that all their vehicles meet homologation requirements. With such a range of variants possible in each model, this can lead to an enormous quantity of testing. However, for the first time, ECE R13 allows homologation to be undertaken by test-supported simulation, and it is now possible to transfer more and more of this work into CAE. This paper describes the results of a project executed at General Motors Europe (GME) in
