The invention discloses a smooth control method for accelerator torque and creeping torque of a vehicle, which comprises the following steps of: calculating P-item torque TPPGain of an accelerator PID (Proportion Integration Differentiation) control module and I-item comprehensive torque TPIGain of the accelerator PID control module according to a difference value between accelerator demand torque Treq and current comprehensive I-item torque TIGain; according to the difference value between the target rotating speed and the current rotating speed, the P item torque TCPGain of the creeping PID control module and the I item comprehensive torque TCIGain of the creeping PID control module are calculated; according to the comparison result of the P item torque of the accelerator PID and the P item torque of the creeping PID, the I item comprehensive torque corresponding to the P item with the large numerical value is fed back as the final I item comprehensive torque TIGain; a driving mode is selected according to the comparison result of the P-item torque of the accelerator PID and the P-item torque of the creeping PID; the comprehensive item torque GovTorque corresponding to the P item with the large numerical value is determined as the final driving total torque; therefore, the condition of torque jump during driving mode switching is avoided, and the purpose of torque smooth control is achieved while starting mode switching is achieved.
本发明公开了一种车辆油门扭矩和蠕行扭矩平滑控制方法,包括:根据油门需求扭矩Treq与当前综合I项扭矩TIGain的差值,计算油门PID控制模块P项扭矩TPPGain、油门PID控制模块I项综合扭矩TPIGain;根据目标转速与当前转速的差值,计算蠕行PID控制模块的P项扭矩TCPGain、蠕行PID控制模块的I项综合扭矩TCIGain;根据油门PID的P项扭矩与蠕行PID的P项扭矩比较结果,将数值较大的P项对应的I项综合扭矩反馈为最终的I项综合扭矩TIGain;根据油门PID的P项扭矩与蠕行PID的P项扭矩比较结果,选择驱动模式;并将数值较大的P项对应的综合项扭矩GovTorque确定为最终的驱动总扭矩;不会出现驱动模式切换时,扭矩跳跃的情况,实现了启动模式切换的同时,扭矩平滑控制的目的。
