step S1, acquiring at least one real-time temperature of the motor driver, and taking the maximum temperature value of the at least one real-time temperature as the working temperature of the motor driver; acquiring real-time power of a motor driver, and taking the real-time power as working power of the motor driver;
step S2, determining the operating state of the working temperature of the motor driver based on the preset upper limit temperature corresponding to various operating states; and adjusting the working power of the motor driver to the power of the corresponding working condition according to the power adjustment rule corresponding to the running state.
The motor driver is a motor control device used in cooperation with the operation of the motor, and can directly convert the battery current into the working current required by the motor. In the scheme, the motor driver can adopt a three-phase inverter bridge power module. The module is provided with a corresponding U-phase UL control submodule and a corresponding UH control submodule; a VL control submodule and a VH control submodule corresponding to the V phase; and the WL control submodule and the WH control submodule corresponding to the W phase.

P＝K*Pm*(T3-Tsm)/(T3-T2)
k is a constant and needs to be calibrated according to different models;
