摘　　要：为了在小型、没有装备液压防抱死系统的电动汽车上实现驱动防滑功能,采用路面自动识别与经验目标值相结合的方法确定目标滑转率,应用积分分离型PID控制算法控制驱动电动机输出转矩,开发了纯电动机控制的驱动防滑系统。在均一路面、对接路面、对开路面以及棋盘路面上进行了电动汽车驱动加速仿真实验。结果表明,开发的驱动防滑系统能够快速、准确地把驱动轮的滑转率控制到目标的滑转率附近,仿真验证了控制算法和控制策略的有效性。To realize the Anti-Slip Regulator（ASR） effect of the down-sized electric vehicles without hydraulic ABS with regula- ting the output torque of the motor,the integral separation PID control algorithm and the road automatic identification algorithm are employed. The control target value of wheelspin rate of driving wheels is determined by the automatic identification value or the empirical value according to the different working condition, and a pure-motor ASR is realized. A series of experimental simu- lations are carried out in different road conditions, including uniform pavement, bisectional road, transition coefficient road and chess road. The results show the proposed ASR can regulate the driving wheels wheelspin rates to the target value quickly and ex- actly, which means the control algorithms and strategies are effective.
