The invention discloses an electromobile driving system rotation-clogging protection method based on a threshold value. The rotating speed of a motor is lower than the lower limit threshold value of the motor, and meanwhile, when a motor torque order from a vehicle control unit is larger than the upper limit threshold value of the motor, rotation-clogging protection can be conducted; when the rotating speed of the motor is larger than the upper limit threshold value of the motor, or the motor torque order is less than the lower limit threshold value of the motor, the rotation-clogging protection can be stopped; when the rotating speed of the motor is lower than the lower limit threshold value of the motor, a relationship between the temperature of a motor power module and the threshold value of the motor is further judged; and after the rotation-clogging protection is started, according to the different relationships between the temperature of the motor power module and the threshold value of the motor, the corresponding torque limiting threshold value is determined, and the motor torque order is limited to be lower than the threshold value to obtain real motor operating torque. According to the electromobile driving system rotation-clogging protection method based on the threshold value, the temperature changes of the motor power module can be fully considered during the motor rotation-clogging protection, the motor operating torque can be faster limited, the temperature rise of the motor and the power module is slowed, and the motor power module and a motor body can be better protected.
