The invention provides an engine torque dynamic control method, which relates to the technical field of vehicle control, and comprises the following steps: S1, judging whether a current system is in an automatic mode or a manual mode, if the current system is in the manual mode, entering a step S8, otherwise, entering a step S2; s2, whether the system is in an economic mode or a power mode is judged, and if the system is in the power mode, the step S4 is executed; s4, entering a power mode, using a power mode plate accelerator Map curve, and if the mode is switched back to the economic mode or the system is switched to the manual mode, entering the step S9; s5, mode judgment is conducted according to the gradient and the load, specifically, S6, an empty mode is entered, and an equant accelerator MAP curve is used in the empty mode; s7, entering a high-grade torque limiting mode; s8, entering a normal mode; and step S9, returning. The fuel economy is improved, and the problem that oil consumption is increased due to excessive engine capacity under part of working conditions is solved.

    本发明提供一种发动机扭矩动态控制方法,涉及车辆控制技术领域,步骤S1:判断当前系统处于自动模式还是手动模式,若是手动模式,则进入步骤S8,否则进入步骤S2;步骤S2:判断系统处于经济模式还是动力模式,若处于动力模式,则进入步骤S4;步骤S4:进入动力模式,使用动力模式版油门Map曲线,若模式切换回经济模式或系统切换为手动模式,则进入步骤S9;步骤S5:根据坡度和载重进行模式判定,包括以下步骤:步骤S6:进入空车模式,空车模式使用等分油门MAP曲线;步骤S7:进入高档限扭模式;步骤S8:进入正常模式;步骤S9:返回。本发明提高燃油经济性,解决部分工况下发动机能力过剩导致油耗升高的问题。
