摘　　要：为了保证电动汽车防抱制动过程的稳定性并充分利用电机控制精确、响应迅速的优势,提出一种基于路面附着的电动汽车再生制动与液压制动防抱协调控制策略。以分布式驱动电动汽车为研究对象,利用电机扭矩和轮缸制动液压压力可实时测量的优势,根据车辆动力学估计路面附着;针对高、中、低3种路面附着采用不同的再生制动与液压制动协调控制策略,并提出了再生制动退出过程中的协调机制。对该策略的仿真结果表明:该协调控制策略可以在制动过程中兼顾制动稳定性和能量回收效率,再生制动退出过程协调机制可以减小液压制动的压力波动,有利于提高车辆的制动稳定性和舒适性。A coordinated control system is developed for the regenerative and hydraulic braking systems in electric vehicles based on a tire-road adhesion model to ensure the stability of electric vehicles with anti-lock braking using motor control accuracy and fast response.The system is designed for a distributed drive electric vehicle with the tire-road adhesion estimated according to the vehicle dynamics.The system measures the motor torque and the wheel cylinder braking pressure.Different coordinated control strategies are given for three tire-road adhesion levels with a coordination mechanism that stops the regenerative braking during anti-lock braking control.Simulations show that this strategy improves both the braking stability and the regenerative energy efficiency during braking.The regenerative braking control reduces the hydraulic braking pressure fluctuations and improves braking stability and comfort.
