The invention discloses a thermal management control method suitable for a new energy commercial vehicle, relates to the technical field of new energy commercial vehicle control, and solves the problems that an existing thermal management control method is complex and poor in heat dissipation effect, and influences the safety and mileage of the whole vehicle. The method comprises air conditioner control and water pump control. The air conditioner control comprises fan control, air conditioner PTC control and air conditioner refrigeration control; the fan control module controls the output power of the fan, linear interpolation maximization operation is carried out by fully considering the motor temperature and the all-in-one center temperature, the heat dissipation problem of the vehicle can be well solved, and the energy consumption of the vehicle is the lowest. Under the condition that the SOC of the vehicle is low, the heating and refrigerating functions of the air conditioner cannot be started, and under the condition that the low electric quantity is guaranteed, energy consumption is reduced to prolong the time for a driver to find a charging pile and increase the endurance mileage. By means of the method, under the condition that it is guaranteed that the new energy commercial vehicle meets the vehicle heat management requirement and the vehicle safety standard, energy consumption is lowest.
一种适用于新能源商用车热管理控制方法,涉及新能源商用车控制技术领域,解决现有热管理控制方法复杂,散热效果差,影响整车安全及行驶里程等问题。该方法包括对空调控制和水泵控制;对空调控制包括对风扇控制、空调PTC控制和空调制冷控制;风扇控制模块中控制风扇输出功率充分考虑了电机温度和多合一中心温度进行线性插值取大运行,能较好的解决车辆散热问题,且使车辆能耗最低。在车辆SOC较低的情况下,无法开启空调的制热与制冷功能,保证低电量情况下,降低能耗以增加驾驶员寻找充电桩的时间及续航里程。本发明方法使得新能源商用车在保证满足车辆热管理需求且满足车辆安全标准的情况下,能耗最低。
