Exploring Automobile's Regenerative Brake Pedal Control Method

摘要: 制动踏板运动信号是驾驶员表达制动需求的唯一方式,再生制动与液压制动联合制动系统中,存在机械制动与电制动之间的过渡产生的波动,反映到制动踏板上造成不良的制动踏板感觉。本文以传统纯液压制动踏板特性为目标,采用轨迹跟踪的控制策略,建立再生制动集成系统制动踏板控制模型,并进行了仿真试验。结果表明:采用这种踏板感觉模拟控制模型,可以实现设定目标车辆制动踏板感觉,并且在再生制动集成系统中可以通过对制动踏板运动状态进行解析制动需求及制动过程中踏板感觉需求。Abstract: The brake pedal movement signal is the only signal for a driver to express his brake demand in a braking system that combines regenerative braking and hydraulic braking.It is prone to bring fluctuations between mechanical brake and electric brake,resulting in a poor brake pedal feel.This paper studies the traditional purely hydraulic braking pedal and uses the trajectory tracking control strategy to establish the brake pedal control model of the combined regenerative braking system.The simulation results show that the brake pedal control model can achieve the predetermined automobile brake pedal feel; the brake demand and pedal feel demand can be obtained by solvingthe brake pedal state motion.
