Game theoretic approach for electrified auxiliary management in high voltage network of HEV/PHEV

International audienceAuxiliary electrification becomes a potential solution to reduce the vehicle energy consumption. However, electrified auxiliaries operate mostly in individual way, non-cooperative in regardless of the vehicle state. In this paper, a new control strategy for electrified auxiliary system is proposed in order to improve the coordination among auxiliaries. This new control strategy is not only based on a game theoretic approach but also a model predictive control (MPC). In this approach, each electrified auxiliary is considered as a player participating in an energy consumption game, where players have incentive to cooperate and improve the global vehicle consumption. Simulation results on a plug-in hybrid electric vehicle show that this new control design provides a promising and simple approach to control the electrified auxiliary system

Impact analysis of the electrified auxiliary system on HEV/PHEV energy efficiency

International audienceIn this paper, we present a completed Hybrid/Plug-in Hybrid Electric Vehicle (HEV/PHEV) model including an Electrified Auxiliary System (EAS), and an impact analysis of this auxiliary system on the vehicle energy efficiency. Our approach focus-es only on three auxiliaries (an electrified air supply system, an electrified refrigerator, and an electric hydraulic power steering) but could be applied on other devices. Numerical simulation shows that this system has a high impact on the energy efficiency of the HEV/PHEV, while its energy consumption could reach up to 18.6% of the total energy requirement for vehicle propulsion. For the purpose of improving the vehicle energy efficiency thank to the electrified auxiliary management, an optimization approach based on forward dynamic programming is developed to determine the optimal auxiliary power consumption profile. The results of this work conduct to some prominent suggestions for the design of the electrified auxiliary management
