Patent attributes
An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The pedal lever operates according to a step-on operation. The lock mechanism can restrict an operation of the pedal lever. The actuator switches 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 not restricted. The ECU includes an actuator control unit and a vehicle drive force control unit. The actuator control unit controls a drive of the actuator. When, during a travel of a vehicle in the locked state, (i) a disturbance is detected and (ii) the locked state is released, the vehicle drive control unit suppresses a vehicle drive force according to an opening degree of the pedal lever than a no disturbance situation.
