  Embedded Vision in the Automotive Domain. Essential Technologies for the Development of Automated Mobilities

  Over the past two decades, the reduction of accidents and fatalities has been achieved in part through the implementation of ADAS. These onboard safety functions rely primarily on the use of exteroceptive vision sensors. To improve the performance and robustness of ADAS, new sensor technologies such as neuromorphic, polarized, and HDR cameras have been developed. These sensors, whether used individually or in combination, enable real-time perception of road scenes, which is essential for the development of new automated mobility solutions. This article provides an overview of these embedded vision sensor technologies, their applications, limitations, and future prospects.

  AI for Environment Perception in Automotive Domain. A Necessity for Automated Vehicles

  Automated mobility increasingly relies on perception systems that are expected to be reliable, robust, and resilient. These systems, whether embedded in the vehicle or deployed in the infrastructure, combine various sensors and, more and more, AI-based algorithms. Their main goals consist to estimate the current state of the road scene key components to generate local dynamic perception maps, which are essential for ADAS. These functions have become critical, as they no longer only provide information (advice, warning) but now enable decision-making and influence the vehicle’s dynamic behaviour. This article summarizes the current state of these perception systems, their applications, and limitations, while exploring the impact of these emerging AI-powered technologies.

  Building Sustainable and Inclusive Mobility through Education. What Implications for the Company?

  In the field of mobility, the leading sector for greenhouse gas emissions in Europe, a world that is a prisoner of travel, transport and the automobile will be neither sustainable nor inclusive. The constant drive to go faster, further and more often is leading us into a dead end. In this article, the authors address these issues by redefining the notion of mobility, and demonstrate that education is essential to make travel more sustainable and inclusive for individuals and communities. They then draw up a precise framework for a commitment of companies to ensure that mobility, based on education, can generate the metamorphoses that give meaning to the life of each individual without exhausting the planet's resources.

  Thermal engines - Next-generation reciprocating engines

  After a reminder of the classification of piston engines, this article focuses on the essential decarbonization of thermal machines by 2030 and beyond. The technological issues that govern the innovations of progress in hydrocarbon-free combustion engines are reviewed. The reactivation of old concepts of alternative engines appropriate to this new context concludes the discussion.

  Life Cycle Assessment of Electric Vehicles

  After a brief review of the key principles of Life Cycle Assessment (LCA), this article shows how this method can be used to evaluate the environmental performance of electric vehicles (EVs) and compare them to that of combustion vehicles. The results presented confirm the relevance of EVs on the "Greenhouse effect" indicator in France, as well as on the other indicators, but also highlight the transfer of impacts. The article also details the methodological changes required for the LCA of electric vehicles, and finally considers the ecological actions available to manufacturers and public authorities for electric mobility.

  Hydrogen Fuel. Production

  Hydrogen has become a full-fledged energy carrier which is expected to play a key role as a fuel in the ongoing transition from fossil fuels to renewable energy. This article reviews its past and future production. Hydrogen can be obtained by water electrolysis. When the source of energy is renewable, this hydrogen becomes 'green' and all the more valuable in terms of energy storage. Other production routes exist from hydrocarbons, alcohols or biomass; these are reforming, partial oxidation and gasification. The CO2 emitted by these methods can be captured and stored.

  Particulate Emissions from Tire-Road Contact

  Fine particle pollution causes over 350,000 premature deaths per year in the EU. Despite the advent of the electric vehicles, emissions of non-exhaust particles (NEP) from transport, particularly those generated by tire-road wear (TRWP), will persist. These emissions are likely to affect public health, causing allergic reactions and respiratory disorders. This article presents the issues and challenges involved in studying TRWP emissions, in particular the variability of their mass granulometry. Finally, a solution for comparing these mass-weighted distributions of TRWP collected on different types of road will be presented via an in-situ study.

  Electric Car, Hydrogen Car

  With over 9 million electric cars sold worldwide in 2023, electric vehicles have become an important means of individual transportation. Around 14,500 hydrogen cars were sold during the same period, marking a growing interest in this field. This article presents some energy aspects related to this type of mobility. Electricity is needed to charge the batteries that are the heart of the electric vehicle. It should also be used to produce hydrogen by electrolysis that will power the fuel cell of the hydrogen car. The objective of these vehicles is to reduce the impact of mobility on the environment. Some economic aspects will also be briefly mentioned.

  Thermal Engine and Climate Change Challenge

  Thermal engines have dominated sectors of economy, and particularly transportation. Their current development and state of the art are the results of XXth century priorities related to economy and environment. In the future, thermal engines will face the challenge of emerging technologies in the frame of sustainable mobility and development. After an analysis of functioning principles and perspectives of development, particularly of combustion engines, thermal engines are compared to other realistic scenarios for transports applications in well-to-wheel and life cycle analysis.

  Polymer Electrolytes for Lithium Metal Batteries

  For applications that require the storage and conversion of large quantities of energy such as electric vehicles and renewable intermittent energy systems, batteries combining high energy density (kWh/kg), low cost (euros/kWh), high reliability and long service life are necessary. Among various technologies under development, “all solid” lithium-metal-polymer batteries are particularly promising. The difficulties of this technology lie in the use of lithium metal at the negative electrode and the development of a polymer electrolyte allowing operation at room temperature. Different strategies developed based on dry polymer electrolytes, plasticized electrolytes, gelled electrolytes and rubber electrolytes are presented in this article.
