The invention discloses a water pump control method, computer equipment, a readable storage medium and a motor vehicle, and relates to the technical field of automobiles. The method includes the following steps that VCU request torque, power module junction temperature, power module NTC temperature, motor temperature, water inlet temperature and water pump gears needed by the VCU request torque, the power module junction temperature, the power module NTC temperature, the motor temperature and the water inlet temperature are obtained, and the maximum value is taken; the required torque of a driver is determined, and the adjustment value of the water pump gear of the cooling liquid is determined according to the required torque; and the sum of the maximum value and the adjustment value is used as an output water pump gear. According to the water pump control method, the water pump gear and the cooling liquid flow are dynamically adjusted according to the real-time conditions of the whole vehicle.

    本发明公开了一种水泵控制方法、计算机设备、可读存储介质及机动车,涉及汽车技术领域,热管理系统通过水泵控制方法控制冷却液的水泵,包括如下步骤:获取VCU请求转矩、功率模块结温、功率模块NTC温度、电机温度和进水口温度以及各自所需的水泵档位,取其中的最大值;确定驾驶员的需求转矩,根据所述需求转矩确定冷却液的水泵档位的调整值;最大值和调整值之和作为输出的水泵档位。本发明所提供的水泵控制方法根据整车适时条件动态调整水泵档位及冷却液流量。
