Study on Regenerative Braking Control Strategy for EV Based on the Vehicle Braking Mechanics

摘要

In order to improve the recovery of braking energy in electric vehicles, a braking force distribution control strategy is proposed which the braking force proportion of the front and rear wheels are distributed according to the brake strength, by analyzing the vehicle braking mechanics and related braking regulation, and combining with the motor output characteristics. A simulation is carried out with SIMULINK/ADVISOR, the results show that, comparing with ADVISOR braking force distribution control strategy, the control strategy not only meets braking stability well, but also there are obvious advantages in energy consumption per 100 kilometers, the rate of braking energy recovery and utilization.
