| Abstract: | To maximize energy recovery, a fuzzy control strategy for regenerative braking of dual- motor driven electric vehicle is proposed. By analyzing the principle of regenerative braking, taking into account constraints, such as ECE regulations, ideal braking force distribution curves, motors, and battery power, using the fuzzy control theory to determine the proportion of motor braking. Under the premise of ensuring the stability of the braking direction, the front- rear axle braking force and the coordinated electromechanical composite braking force are reasonably distributed. Simulation and hardware-in-loop test verification are made to the control strategy under different conditions with MATLAB/ Simulink. The results show that the designed control strategy can realize the coordination of the electromechanical composite braking system, effectively extending the driving range. |
