摘　　要：为了研究汽车起步过程中离合器的受力特性以及控制策略,建立了离合器接合过程的数学模型;分析了接合过程中离合器压力模糊控制原则,设计了离合器起步模糊控制算法,建立了离合器接合仿真模型并进行了仿真。仿真结果表明,所设计的离合器转矩模糊控制器能够保证离合器在低速时快速接合,同常规比例控制相比,能够显著减小滑磨功,同时减小了因离合器接合而对发动机造成的冲击。To study the force characteristic and control strategy of wet clutch when starting, the mathematical model of joint process of clutch is established firstly; and the fuzzy control principle of clutch pressure is discussed. A fuzzy control algorithm for clutch is proposed and the simulation model for clutch jointing is developed. The simulation result shows that the torque fuzzy controller can guarantee the clutch joints quickly at low engine speed. Comparing with regular proportional control, the fuzzy control method can reduce friction loss remarkably and meanwhile decrease the impulsion to engine in the process of clutch jointing.
