Study on the Improved Parallel Braking Control Strategy of Range-extended Electric Commercial Vehicle

For the problems of electric vehicle regenerative braking, an improved parallel braking control strategy model at Cruise and Matlab/Simulink co-simulation environment was established under the braking constraints. Then UDC cycle is used to verify the performance of brake control strategy. The simulation results show that the improved parallel braking control strategy can optimize the brake force distribution, and maximize the braking energy recovery under ensuring the best braking performance, so the braking performance is improved and meanwhile the vehicle economy is largely enhanced.
