The invention discloses an engine and clutch torque control method for changing a driving intention. The method comprises the following steps that (1) engine and transmission input signals of a current software operation period are collected through a TCU; (2) when the following conditions are simultaneously met, entering an engine torque and clutch control stage for changing the driving intention; and (3) controlling the real-time output torque of the engine and the combination torque of the clutch according to the following mode. The engine torque is limited in the working condition of changing the driving intention by stepping on the accelerator in the upshift process, and meanwhile, the clutch torque combination amount is controlled, so that the engine torque is maintained at a small output torque value in the process that the engine rotating speed is close to and exceeds the shaft rotating speed, impact generated by changing of the torque transmission direction is eliminated, and the torque transmission efficiency is improved. And the riding comfort is improved.
发明公开了一种改变驾驶意图的发动机与离合器扭矩控制方法,包括以下步骤:1)通过TCU采集当前软件运算周期的发动机及变速器输入信号;2)当以下条件同时成立时,进入改变驾驶意图的发动机扭矩与离合器控制阶段:3)按照下列方式控制发动机实时输出扭矩及离合器结合扭矩。本发明在升档过程踩油门改变驾驶意图工况中对发动机扭矩进行限制,同时控制离合器扭矩结合量,使发动机转速在接近并超过轴转速过程中发动机扭矩维持在较小的输出扭矩值,以消除扭矩传递方向改变而产生的冲击,提高乘车舒适性。
