Cooperative Distribution Strategy of Regenerative Braking and Pneumatic Braking of an Electric Commercial Vehicle 2019-01-5039

This paper mainly proposes one type control strategy of the regenerative braking system of an electric commercial vehicle under normal braking condition. With the main goal of recovering as much energy as possible, the braking force distribution strategy based on maximum regenerative braking optimization is studied under the restriction of ECE regulation and state of charge (SOC) of battery. Firstly, the related models of the regenerative braking system and the target vehicle are separately established in MATLAB/Simulink. Then, the distribution strategy of braking force is developed and optimized considering the influence of SOC and vehicle speed respectively. Finally, the braking effects of this control strategy in the typical deceleration process are numerical simulated and analyzed. Simulation results depict that this control strategy can recover more braking energy under the premise of ensuring braking safety and great braking performance compared with the common braking strategies with traditional strategy and without regenerative braking.
