电动汽车再生制动与防抱死制动协调控制

On coordination control of regenerative braking system and anti-lock braking system for electric vehicle

以电动汽车的再生制动与防抱死制动系统协调控制为研究对象,提出一种协调控制方法.采用滑模控制研究防抱死,并证明带有电机制动力矩时控制的稳定性.进而提出不影响滑模控制的滑移率门限值,并设计了协调控制算法.最后,在Simulink环境下搭建了整车模型,选择高、低附着系数路面工况对所提出策略进行仿真,结果验证了协调控制算法的正确性.

In this paper,the coordinated control of the regenerative braking system and anti-lock braking system of electric vehicles is taken as the research object,and a coordinated control method is proposed.Sliding mode control was used to study anti-locking and to demonstrate the stability of control with motor braking torque.Further,a slip ratio threshold value that does not affect the sliding mode control is proposed.And coordinated control algorithm is designed.Finally,the vehicle model was built in the Simulink environment,and the proposed strategy was simulated by selecting the high and low adhesion coefficient road conditions.The results verified the correctness of the coordinated control algorithm.
