1. A pedal fault diagnosis method, comprising:
detecting a driver seat is in an unmanned state;
measuring an actual zero position voltage of a pedal while the driver seat is in the unmanned state;
determining, based on the actual zero position voltage, that a zero position fault exists on the pedal; and
controlling a vehicle to enter a speed limiting mode, wherein the speed limiting mode controls a speed of the vehicle to be less than or equal to a first safe speed threshold.
