Classification: CPC B  G | IPC B  G

Claim 18:
19. 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, the lock mechanism comprising:
a locking member, a biasing member, and an accommodation chamber,
wherein the accommodation chamber is fixed relative to a pedal housing,
the biasing member includes a first end and a second end, wherein the first end of the biasing member contacts a first end of accommodation chamber and the second end of the biasing member contacts the locking member to bias the locking member to protrude out of a second end of the accommodation chamber;
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 configured to control a driving operation of the actuator, wherein
the controller is configured to increase an energization amount to the actuator to increase a lock holding force by the lock mechanism, in response to a detected disturbance during a vehicle traveling in the locked state in order to prevent lock releasing;
wherein the lock mechanism holds the locked state in a state where energization to the actuator is turned off.
