The embodiment of the invention provides a torque safe control method of a new-energy automobile. The method mainly comprises the steps that according to monitored motor parameter information of the new-energy automobile, motor actual torque of the discharging end of a battery is calculated, and according to monitored clutch parameter information of the new-energy automobile, actual output torque of the clutch end is calculated; the difference value between the motor actual torque of the discharging end of the battery and the actual output torque of the clutch end is calculated, the difference value is compared with a preset threshold value, and according to a comparison result, target output torque of the motor is determined. According to the method, the motor actual torque of the discharging end of the battery and the actual output torque of the clutch end are compared and judged, target output torque, output by a whole vehicle controller, of the motor is reasonably judged, and the target output torque of the motor, needed torque of a driver and needed torque of a monitoring layer are further compared, so that safe monitoring and coordination of torque of the automobile are achieved, driving safety is ensured.
