  • Publication number: 20230065963
    Abstract: 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 the 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 include a lock operation determination unit and an actuator control unit. The lock operation determination unit determines switching of the lock/unlock operation by the lock mechanism, in response to a voice instruction of a driver. The actuator control unit controls a drive of the actuator according to a determination result of the lock operation determination unit.

  • Patent number: 9846448
    Abstract: A pedal-side rotating member is composed of a boss portion rotatably supported by a pedal shaft, a spring holding portion for holding one end of a return spring, a stopper arm being operatively in contact with an inner wall surface of a supporting body, and a mechanically-weaker portion, wherein the boss portion, the spring holding portion, the stopper arm and the mechanically-weaker portion are integrally formed as one unit. The spring holding portion is so configured as to be broken away from the boss portion at the mechanically-weaker portion, if an acting force larger than a predetermined value is applied to the stopper arm when the rotating member is rotated in a direction to an acceleration fully-closed position. A broken piece is held at a position inside of the supporting body, so that rotation of the boss portion is not adversely affected by the broken piece.
