Classification: CPC B  G | IPC B  G

Claim 0:
1. An accelerator pedal system comprising:
a pedal lever configured to be operable in accordance with a step-on operation;
a lock mechanism configured to be capable of restricting the operation of the pedal lever;
an actuator configured to switch between a locked state in which the operation of the pedal lever is restricted by the lock mechanism and an unlocked state in which the operation of the pedal lever is free from restriction by the lock mechanism; and
a controller including
a lock operation determination unit configured to determine switching of a lock operation by the lock mechanism, and
an actuator control unit configured to control a drive of the actuator,

wherein
the controller is configured to set an automatic driving mode, an override mode in which an input by the step-on operation is always prioritized when both an automatic driving and the step-on operation are input, or a manual mode, as a vehicle driving mode, and
the controller is further configured to:
transition to the locked state in the automatic driving mode,
switch to the override mode when the pedal lever is pressed to release the locked state and transition to the unlocked state, and a pedal opening degree is equal to or larger than an override start opening degree for starting the override mode, and
resume the locked state, when a state in which the pedal opening degree is smaller than the override start opening degree is continued at least for a standby time.
