摘　　要：预测控制原理以ABS系统为基础,通过实时检测汽车行驶车速、车轮转动角速度和转向盘转角信号来预测汽车急转向时的状态,对汽车的个别车轮主动施加大小不同的制动力,以产生一个与横摆力矩相平衡的反作用力矩,防止汽车产生急转侧滑现象,同时提高汽车急转向时的操纵稳定性,对减少道路交通事故的发生具有十分重要的意义。Presents the predictable control principle for the slide in crisis turn. Anti-lock brakes sensors monitor everything from steering-wheel position, tire speed and vehicle speed while cornering. If the sensors detect that a driver is about to lose control, the control system applies individual brakes. The braking force of the tires is assumed to be regulated by a control system, which is opposite to any yawing moment. The method enhances the vehicle performance and stability in crisis turn.
