摘　　要：应用遗传算法设计了驱动防滑控制系统的参数自整定油门位置及驱动轮制动压力增量PI控制器。论述了其设计过程,建立了调试控制算法的半实物仿真器,针对典型附着路面进行了半实物仿真研究。结果表明:控制算法能自动识别路面附着变化,有效抑制驱动轮过度滑转,改善汽车的加速性。Genetic Algorithm was used to design self-adjusting increment PI controllers of engine throttle position and driving wheel brake pressure. The process of design was described, the hardware-in-the-loop simulator used to debug control algorithms was erected, and the simulation of accelerating on typical roads such as ice and snow was made. The results show that the excessive slip of driving wheel can be identified and eliminated effectively, and the acceleration performance is improved.
