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.

Abstract: An accelerator pedal system includes 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, and 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. In the accelerator pedal system, a controller configured to change an energization amount to the actuator when a disturbance is detected during a vehicle traveling in the locked state. Thus, the lock state can be suitably controlled.

Abstract: An accelerator pedal system includes a pedal lever that performs an operation in accordance with a step-on operation, a lock mechanism configured to restrict the operation of the pedal lever, and 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 not restricted by the lock mechanism. A controller includes a locking operation determination unit that determines switching of a locking operation by the lock mechanism, an actuator control unit that controls a driving operation of the actuator, and an information acquisition unit that acquires vehicle speed information. The locking operation determination unit locks the pedal lever when a vehicle is traveling in an automatic driving mode and when a vehicle speed is equal to or more than an activation-determination lower limit value.

Abstract: An accelerator device having an organ structure includes: a pad configured to be pressed by a driver; a case configured to be attached to a vehicle body; an inside movable mechanism housed in the case; and an arm that passes through an opening formed in an outer wall of the case and connects the pad to the inside movable mechanism. The arm has a rectangle shape in a cross section. An entire circumference of the opening is surrounded by a protrusion protruding toward the pad. The protrusion includes an upper surface, and the upper surface has an inclination portion that slopes down rightward or leftward, when viewed from the pad.

The lock operation determination unit determines switching of the locked state and the unlocked state by the lock mechanism. The actuator control unit controls a drive of the actuator. The lock operation determination unit releases the locked state of the pedal lever when a driver's intention to accelerate is detected while a vehicle is traveling in the locked state.

Abstract: An accelerator device includes a housing, a rotary shaft, and an operating member. The operating member is configured to move in an opening direction and a closing direction. The operating member includes a first contact portion arranged at a first distance from the rotary shaft and a second contact portion arranged at a second distance from the rotary shaft. When the first contact portion has an initial shape and the operating member is located at the accelerator idle position, the second contact portion is arranged at a predetermined distance from the inner wall. When the first contact portion is deformed more than a predetermined volume from the initial shape and the operating member is located at the accelerator idle position, the second contact portion is in contact with the inner wall.

Abstract: A pedal pad is applied to a pedal device that outputs a signal corresponding to an operation amount of a depressing operation by an operator's foot. The pedal pad includes a pad member and a hinge member. The pad member is depressed by an operator's foot. The hinge member connects the pad member to a base of the accelerator device. The hinge member has a convex portion that is locked to the pad member and has a flat locking surface that is not perpendicular to the hinge shaft.
