摘　　要：根据Carsim整车动力学模型,结合逻辑门限控制理论和PID控制理论,建立了基于滑移率误差的ABS控制器,并应用Matlab/Simulink进行了冰雪路面上车辆紧急制动过程的仿真分析。仿真结果表明:设计的基于滑移率误差PID控制策略比单一滑移率逻辑门限的控制策略更能满足预定目标,车辆的制动效果得到了明显改善。Combining the logical threshold control theory and the PID control theory, ABS controller based on slip rate er- ror is established according to the vehicle dynamics model in the software of Carsim. The simulation analysis of the emergen- cy braking process of the vehicles on the ice and snow road is carried out by the software of Matlab/Simulink. Simulation re- suhs show that the designed PID control strategy based on the slip rate error is more satisfied with the predetermined target than the single logical threshold control strategy based on slip rate, and obviously improves the braking effect.
