The invention relates to a temperature control method and module for a heat dissipation systemof a new energy commercial vehicle. The method comprises the steps: determining the working state of a drive motor according to the temperature of the drive motor, the torque of the drive motor, the rotating speed of the drive motor, the temperature of cooling liquid, the temperature of external air, the output voltage of a motor controller, and the output current of the motor controller; and according to a control function associated with the energy optimization control function and the target temperature steady-state control function, calculating the optimal target temperature of the driving motor, and outputting a corresponding PWM fan control signal. The energy utilization efficiency of the new energy commercial vehicle is improved, and energy conservation and emission reduction are achieved. A corresponding hardware module is designed based on the used method. By adopting the hardware module and the method, optimal balance between the heat loss of the driving motor and the power consumption of the heat dissipation system is achieved by optimizing the output of the heat dissipation system. When the driving motor operates in the safe temperature interval, the sum of the heat loss of the driving motor and the power consumption of the cooling system is reduced, and energy conservation and emission reduction are realized.
