The invention provides a hydrogen fuel cell automobile motor phase sequence self-recognition system and method. The system comprises a rear motor controller, a motor, a whole vehicle controller, a brake pedal and an accelerator pedal. The vehicle control unit is connected with the brake pedal and the accelerator pedal through signal acquisition lines; the whole vehicle controller, the motor and the rear motor controller are connected through CAN communication signal lines. The vehicle control unit collects depth information of an accelerator pedal and a brake pedal, controls a motor according to the demand of a driver, and sends target torque; the rear motor controller outputs the target torque, meanwhile, the motor is controlled to execute the target torque to obtain the rotating speed of the motor, and the vehicle control unit obtains the rotating speed information of the motor, the phase current information of the motor and the current information of the direct current input end of the rear motor controller so as to recognize and adjust the phase sequence of the motor. The system is simple in structure, low in cost, high in stability and reliability, wide in application range, low in misjudgment rate and reliable in control, and has an instrument prompting function.
