摘要
针对某越野车,开发了直流电机驱动的AMT离合器执行机构。建立了发动机模型、离合器模型以及传动系模型。通过对冲击度和滑磨功的分析,在车辆起步离合器慢接合阶段制定了一种基于模糊控制和模糊PID的智能控制策略并建立了其仿真模型,利用Matlab/Simulink对车辆起步离合器接合全过程进行仿真分析,仿真结果表明该控制策略对于驾驶员的不同意图以及离合器负荷的非线性变化具有很好的自适应性。
The DC-motor-driven AMT clutch actuator was developed for an off-road vehicle.Engine model,clutch model and driveline model were built.Through analysis of the jerk and the friction work,an intelligent control strategy based on fuzzy control and fuzzy PID was proposed and its simulation model was built in slow clutch engagement stage during vehicle starting.Through simulation analysis of clutch engagement process during vehicle starting in Matlab/Simulink,results show that this control strategy has good self-adaptability for different driver＇s intentions and nonlinear change of clutch load.
