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 a lock operation determination unit and an actuator control unit. 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: A supply oil passage is defined in a sleeve and communicates to a feed port to which oil is supplied. A valve object is able to be seated on or separated from a valve seat defined on an inner wall of the supply oil passage. A guide wall is defined by an inner wall of the sleeve, and the valve seat is located between the feed port and the guide wall. A forward flow port extends from the guide wall to an oil passage of an attachment component. A pressure chamber is defined in the sleeve, and the valve seat is located between the supply oil passage and the pressure chamber. A backflow port always allows the pressure chamber and the oil passage of the attachment component to communicate with each other. The forward flow port is located between the valve seat and the backflow port.

Abstract: A pedal device includes a pedal lever, an actuator, and a control unit. The pedal lever operates in response to a pedal operation. The actuator can apply a reaction force that is a force in a direction of returning the pedal lever by driving a motor. The control unit includes a current command calculation section that calculates a current command value based on a reaction force target value related to a reaction force applied to the pedal lever and a duty calculation section that calculates a duty command value based on the current command value, and controls a drive of a motor based on the duty command value. The duty calculation section corrects the duty command value based on at least one of a motor current supplied to the motor and a rotation speed of the motor.

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 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: A valve timing adjustment device includes: a first rotatable body that is rotated about a rotational axis synchronously with one of a drive shaft and a driven shaft of an engine; and a second rotatable body that is rotated about the rotational axis synchronously with the other one of the drive shaft and the driven shaft. The first rotatable body includes: a fastening portion, a slide portion and a bearing portion. The fastening portion is fastened to the one of the drive shaft and the driven shaft. The bearing portion includes an outer peripheral surface that is opposed to an inner peripheral surface of the second rotatable body, and the bearing portion rotatably supports the second rotatable body. The fastening portion projects on one axial side of the slide portion and the bearing portion in an axial direction toward the one of the drive shaft and the driven shaft.

Abstract: Each of an external tooth-bottom surface and an external bottom-side contact surface has a cross-sectional shape formed by a hypocycloid curved line. An external front-side contact surface has a cross-sectional shape formed by an epicycloid curved line. An external tooth-front surface is formed at a radial-inside position of a reference epicycloid curved line, that is, a position closer to a first pitch circle of an external gear. A possible contact between a tooth-front portion of the external gear and a tooth-front portion of an internal gear can be avoided. A connecting point between the external tooth-front surface and the external front-side contact surface is located at such a position that a contact surface length of an external tooth-contact surface is larger than twenty percent of a total tooth surface of the external gear.
