摘要
针对电子机械制动系统(EMB)车辆进行研究,给出了简化的车辆仿真模型和EMB制动器仿真模型,并结合路面识别技术为之设计了相应的ABS模糊PID控制器仿真模型。ABS制动控制器模型采用基于车轮最优滑移率的控制策略,最优滑移率由路面自动识别系统准实时的得出,ABS控制算法采用模糊PID控制,对EMB制动器进行滑移率S和制动压力F的闭环控制。仿真采用Matlab中的simulink工具箱建模,仿真结果证明路面识别系统能够正确识别路面并确定最优滑移率,基于EMB制动控制器的车辆的ABS控制器始终将制动过程滑移率控制在路面识别系统确定的最优滑移率附近。
The designing of the ABS Controller based on electromechanical brake system and optimal slip ratio is studied. Firstly simplified wheel model and EMB controller model is given,then a corresponding ABS brake controller was designed. The fuzzy-pid ABS controller adopts optimal slip ratio based control scheme,we can achieve the optimal slip ratio from the automatic identification system. The ABS controller can gives a closed loop control of slip ratio S and brake press force F. The simulation model is founded by using simulink toolbox of Matalab. The result shows the road surface automatic identification system can identify the road surface correctly and ABS controller can keep the slip ratio close to the optimal slip ratio.
