摘要： 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.

摘要： 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.

摘要： 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.

摘要： An actuator is provided in an actuator housing. A lever is provided in the actuator housing, rotates by driving force from the actuator, contacts an arm that rotates together with the pedal, and is capable of imparting a reaction force to the pedal against a driver's depression force. A fixing member is formed so that a pedal housing and the actuator housing are fixed apart from each other, and are attachable to a vehicle. A positioning portion determines a contact position between an arm and the lever and between a rotation axis of the pedal and a rotation axis of the lever.

摘要： An accelerator device includes a pedal lever, at least one drive source, a power transmission mechanism, and a locking mechanism. The pedal lever operates in response to a depressing operation. The drive source is configured to exert a reaction force as a force in a returning direction to the pedal lever. The power transmission mechanism transmits a drive force from the drive source to the pedal lever. The locking mechanism is capable of regulating the operation of the pedal lever.

摘要： A power transmission mechanism of an accelerator device includes a first power transmission member, a second power transmission member, a coupling elastic member, and an actuator lever, and applies a reaction force to a pedal lever via the first power transmission member, the second power transmission member, and the actuator lever using a driving force of a drive source. The first power transmission member has a first stopper, and the driving force is transmitted to the first power transmission member. The second power transmission member has a second stopper that comes into contact with the first stopper. The first stopper and the second stopper are separated from each other in an initial state, and when the drive source is energized, and come into contact with each other when the first power transmission member is driven against an elastic force of the coupling elastic member by energizing the drive source.

摘要： 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.

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 a lock operation determination unit and an actuator control unit. The lock operation determination unit resumes the locked state by the drive of the actuator after a release from the locked state due to the step-on operation of the pedal lever during the automatic drive control in the locked state, when (i) the automatic drive control is continued or (ii) a resuming of the automatic drive control is detected.
