Abstract: In order to solve the problems of safety risk and poor economy of the electric vehicle, the braking regulation and vehicle dynamics were investigated. After the analysis of the braking regulation and vehicle dynamics, a control strategy for regenerative braking system of pure electric passenger vehicle was established, according to the different braking strength value, braking force distribution control strategy was carried out to allocate more braking force to the drive shaft to use the regenerative braking system as much as possible, so the method was presented to secure the safety of the braking system and regenerate the maximum energy in the braking process of electric vehicle, ADVISOR2002 simulation platform was used for vehicle dynamics, and a real car test was carried out on the chassis dynamometer in the laboratory. The experiment result showed that contribution rate for electric range is more than 32% in the ECE test cycle, the brake safety is secured, and the economy of the pure electric passenger vehicle is improved.
Key words: pure electric passenger car; regenerative braking; control strategy
