摘　　要：建立了四轮驱动汽车加速过程的数学模型,以滑转率为调节对象,提出一种基于模糊P ID控制的驱动防滑控制A SR算法。设计了以发动机油门为控制对象的模糊-P ID控制器并讨论了控制器切换参数的选取,并针对均一低附着路面以及分离路面在S im u link仿真环境下进行了动态仿真。对比仿真结果,表明模糊P ID控制性能优于单一的模糊控制。A dynamic model on four-wheel drive vehicle was established and an acceleration slip regulation （ASR） algorithm based on fuzzy-PID control was realized through rectifying the output torque of engine, switching parameter of fuzzy-PID controller was studied. The fuzzy logic controller was designed with Matlab fuzzy control toolbox. Contrastive simulation has been carried out with Simulink, which has the result that the ASR based on fuzzy-PID control is super to the pure fuzzy control in controlling effect.
