ORQA : un canevas logiciel pour la gestion de l'énergie dans les véhicules électriques

Abstract : Electric vehicles are nowadays a viable alternative to vehicles built around an internal combustionengine. They offer a cleaner and more comfortable driving thanks to the electric engine. The energymanagement of an electric vehicle is usually focused on the engine operation, the biggest energyconsumer, thus ignoring the user comfort.The contribution presented in this thesis allows for the consideration of the user preferences insidethe energy management of electric vehicles. It takes shape with a framework named ORQA. First,the vehicle devices are characterised by their energy requirements and the quality levels they offer.An energy manager based on the devices characteristics is then integrated into the software systemof the vehicle. The manager offers the user a solution to configure a trip request. The configuration isbased on the usage preferences and optional constraints over duration and consumption. The solutiondefines a set of constraints on the motor and on the comfort-related devices during the trip execution.The energy manager is executed in the embedded systems of the vehicle which platforms are highlyconstrained. Thus, the energy manager’s implementation is optimised to satisfy the execution platformconstraints. The interest and the validity of the chosen approach are attested by the comparison ofthe original configuration and an optimised configuration on two example vehicles.
