Abstract: 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.

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 pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. The pedal lever operates in accordance with a step-on operation. The lock mechanism is capable of restricting the operation of the pedal lever. The lock mechanism can switch 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. The ECU includes a locking operation determination unit, an actuator control unit, and an information acquisition unit. The locking operation determination unit determines switching of a locking operation by the lock mechanism. The actuator control unit controls a driving operation of an actuator. The locking operation determination unit locks the pedal lever when the vehicle is traveling on a specific position in an automatic driving mode.

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 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.

Abstract: A fuel supply device (1) has a valve (13) in a fuel passage between a fuel pump (3) and an engine (5). In a storage portion of an ECU (18-21) is stored a relationship between a fuel pressure and a flow rate, which are required by the engine, and voltage which is supplied to a motor (7). The ECU senses voltages V26, V27, V28 supplied to the motor from a controller (22) when the valve is opened from change points C1′, C2′, C3′ at which a characteristic between the voltage and the current which are supplied to the motor (7) is changed. Then, the ECU corrects the voltage stored in the storage portion on the basis of differences between voltages V1, V2, V5 stored in the storage portion at the change points C1, C2, C3 and the voltages V26, V27, V28 when the valve is opened. In this way, the fuel supply device can correctly control the motor in correspondence to the fuel pressure and the flow rate which are required by the engine.

Abstract: An accelerator pedal system includes a pedal lever, a lock mechanism, an actuator, and an ECU. 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 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.

Abstract: 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.
