摘　　要：分析了车辆制动过程的数学模型,为了克服模型非线性、变参数对系统的影响,采用了参考模型自适应控制。为了适应各种路况条件,使车辆以比较理想的滑移率制动,缩短制动时间,提出了滑移率自适应调节方法。通过仿真证明,该方法简单可行,控制效果好。In this paper the model of the vehicle-braking process was analyzed. To prevent the influence of nonlinear and parameter-variations of the model on the system, the model reference adaptive control was applied. The main control strategy is to force the vehicle to brake at optimal slip ratio and to minimize the vehicle stopping time. In order to adapt to different road surfaces, an adaptive-adjusting method of wheel slip ratio is proposed. Simulation studies proved that this method is simple and reasonable.
