Description
Abstract Aiming at the distributed drive electric vehicle, according to the actual demand of the composite braking system of the electric vehicle, the distributed parallel braking control strategy is proposed based on braking safety and energy recovery. The strategy adopts a hierarchical control structure. The upper control strategy aims to ensure the stability of vehicle braking during braking. The lower controller performs secondary distribution of motor braking torque on the basis of the upper control. The designed parallel braking control strategy considers the front and rear axle braking force distribution, battery SOC, charging power, motor external characteristics and slip rate. Finally, the simulation analysis is carried out to verify the braking efficiency and energy recovery effect.
