Braking Force Distribution of Electric Vehicles Based on Fuzzy Control

How to reasonably distribute the braking force on the front and rear wheels is one of the important factors that affect the safety performance of vehicle. Besides, the number of braking energy recovery has become an important issue. In order to solve these problem, this paper comes up with a novel control strategy of braking force distribution of electric vehicle (EV) based on fuzzy control theory. First and foremost, the braking force of the front and rear axle of vehicle is allocated on the basis of optimized fixed proportion to ensure that vehicle has good braking performance under any braking demand, and then the fuzzy controller is designed to calculate the regenerative braking force. Finally, combining fuzzy control with fixed proportion allocation strategy, we can recover the braking energy as much as possible on the premise of verifying the braking safety of vehicles. Theoretical analyses and simulation results show that the proposed control strategy is effective for improving braking performance and increasing the efficiency of energy recovery.
