The invention relates to a new energy automobile electronic oil pump fault processing method. According to the method, different oil pump fault levels are defined, input signals are received and processed, preconditions of various oil pump faults are calculated, whether the current oil pump fault meets the preconditions or not is judged, whether the current oil pump fault meets a certain fault frequency threshold value or not is judged, and the torque limit value of the current oil pump fault level is calculated. And the recovery condition of the current oil pump fault level is calculated, and the motor torque is limited or recovered. According to the method, real-time protection can be provided for the motor of the new energy automobile, motor damage caused by over-temperature of the motor is prevented, the service life of the motor, the service life of the controller and the service life of the speed reducer are prolonged, and the service life of the new energy automobile is prolonged.
