The invention discloses a torque control method, computer equipment, a readable storage medium and a motor vehicle, and relates to the technical field of automobiles, and the torque control method comprises the following steps: a motor controller calculates the junction temperature of a power module according to three-power operation parameters and a water pump gear, and calculates a first amplitude limiting torque according to the junction temperature of the power module; the motor controller obtains a current limit value according to the three-power operation parameters and the water pump gear, and calculates a second amplitude limiting torque according to the current limit value; and the smaller value of the first amplitude limiting torque and the second amplitude limiting torque is taken as the output torque. According to the torque control method, torque output and water pump gears can be adjusted in real time according to the running condition of the whole vehicle.

    本发明公开了一种扭矩控制方法、计算机设备、可读存储介质及机动车,涉及汽车技术领域,包括如下步骤:电机控制器根据三电运行参数和水泵档位计算功率模块结温,并根据功率模块结温计算第一限幅扭矩;电机控制器根据三电运行参数和水泵档位获取电流限值,根据电流限值计算第二限幅扭矩;第一限幅扭矩和第二限幅扭矩中取较小值作为输出扭矩。本发明所提供的扭矩控制方法能够根据整车运行情况实时调整扭矩输出以及水泵档位。
