Fuzzy Control Strategy and Simulation Analysis of Braking Energy Recovery for Pure Electric Vehicles

Qin Zhuogeng

Abstract：In order to improve the braking energy recovery level of pure electric vehicles and improve the energy utilization rate， this paper proposes a regenerative braking force distribution method based on fuzzy control. According to the principle of automobile braking operation， combined with energy recovery conditions， this method designs corresponding fuzzy control rules to effectively distribute the regenerative braking force. Through the simulation test， the design scheme was verified， which can be used as a reference for the design of energy recovery control in the research and development of pure electric vehicles.
