The invention discloses a control method for fault diagnosis of an accelerator pedal of a new energy vehicle, and relate to the field of vehicle control of new energy vehicles. The method comprises: acquiring output signals of an accelerator pedal to obtain an accelerator pedal pre-outputting signal; determining whether the accelerator pedal pre-outputting signal is normal or not; if the accelerator pedal pre-outputting signal is determined to be normal, using the accelerator pedal pre-outputting signal as an accelerator pedal outputting signal; if the accelerator pedal pre-outputting signal is determined to be abnormal, using the stored accelerator pedal outputting signal which is determined to be normally previously or a preset signal as the accelerator pedal outputting signal. The method can determine transient faults or permanent faults of an accelerator pedal through performing fault zone bit anti-shaking processing on two paths of output signals of the accelerator pedal, so as to realize rational fault processing on different fault types of the accelerator pedal, and ensure security of driving of a finished vehicle.
