1. An accelerator pedal system comprising:
a pedal lever configured to perform an operation in accordance with a step-on operation;
a lock mechanism configured to restrict 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 an actuator control unit configured to control a driving operation of the actuator,
wherein the actuator control unit is configured to change an energization amount to the actuator when a disturbance is detected during a vehicle traveling in the locked state;
wherein the lock mechanism holds the locked state in a state where energization to the actuator is turned off, and
when the disturbance more than a determination threshold is detected, the controller starts energization to the actuator from a state in which the actuator is not energized, to prevent a lock releasing, and
when the disturbance is detected to be smaller than the determination threshold in the locked state, the controller terminates the energization to the actuator to maintain the locked state.
