In car embedded electronic architectures: how to ensure their safety
Abstract
The part of software based systems in a car is growing. Moreover, in the next years will emerge the X-by-Wire technology that intends to replace mechanical or hydraulic systems by electronic ones even for critical function as braking or steering. This requires a stringent proof that these new vehicles will ensure the safety of driver, occupants, vehicle and environment. In this paper, we intend to list certain activities and key points for ensuring the development of a safe and optimized embedded system. More precisely, we propose two main axis that contribute to establish a design methodology of such systems. The first one identifies the generic components of an embedded system while the second one details how to model and validate the embedded system throughout the different steps of the development process. || On assiste actuellement à un accroîssement de la part de l'informatique embarquée dans une automobile. De plus, dans les prochaines années, les systèmes X-by-Wire remplaceront de plus en plus les systèmes traditionnels reposant sur des technologies mécani
