Considering the high order nonelinearly and mutiple - input - mutiple - output coupling effect of the system , different driving condition and complex external disturbance , hybrid fuzzy - pid control with parameters selfturning is adopted in engine speed control system , the simulation which is integrated with vehicle model in the matlab environment shows that the performance and fuel economy of the car with pscvt is better than those of car with the standard manually shifted transmission
考虑到车辆系统的高阶非线性和输入输出的耦合效应及汽车运行的复杂工况和外界环境干扰等因素的影响，提出了混合模糊? pid控制算法用于变速系统速比的控制，并结合整车的数学模型在matlab下进行了计算机的动态仿真。
