Abstract: A forward phase adjustment unit adjusting a forward phase of a forward intermediate rotor relative to a crank shaft includes a forward stopper mechanism and a forward locking mechanism and a forward biasing mechanism. The forward stopper mechanism prevents further advance of the forward phase by engaging the forward intermediate rotor at a forward most-advanced phase. The forward locking mechanism locks the forward phase when reaching the forward most-advanced phase at a start time of the engine. The forward biasing member biases the forward intermediate rotor in an advance direction. A backward phase adjustment unit adjusts the backward phase of the intake cam shaft relative to a backward intermediate rotor by receiving a cam torque that is biased on average in a retard direction. The backward phase adjustment unit includes a backward stopper mechanism and a backward locking mechanism. The backward stopper mechanism prevents further retard of the backward phase by engaging the intake cam shaft at a backward most-retarded phase. The backward locking mechanism locks the backward phase when reaching the backward most-retarded phase at the start time of the engine.

Abstract: An accelerator device includes a pedal lever, a drive source, a power transmission mechanism, and a control unit. The pedal lever is operable in response to a pedaling operation. The drive source generates a driving force when being energized. The power transmission mechanism transmits the driving force of the drive source to the pedal lever, and applies a reaction force in an opposite direction to a pedaling direction of the pedal lever. The control unit includes a reaction force controller that controls the reaction force applied to the pedal lever by controlling the drive source. The reaction force controller holds an initial reaction force for a reaction force hold time from a start of reaction force application, and performs a reaction force reduction control in which the reaction force is reduced as a time function after an elapse of the reaction force hold time.

Abstract: 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.

Abstract: A brake pedal is operated by a pedal force of a driver. A sensor is capable of detecting a stroke amount of the brake pedal. A brake circuit generates braking force to apply a brake to a vehicle by applying hydraulic pressure to wheel cylinders provided to respective wheels. An electronic control device controls the braking force generated by the brake circuit based on an output signal from the sensor and a state of the vehicle. The electronic control device executes predetermined braking force control under which the braking force generated by the brake circuit is set to be predetermined braking force, when the stroke amount of the brake pedal is between a first threshold and a second threshold larger than the first threshold.

Abstract: A brake device for a brake-by-wire system includes a brake pedal, a sensor, a reaction force generator, and a reaction force changing mechanism. The brake pedal is rotatably mounted on a housing and not mechanically connected to a hydraulic pressure generator. The sensor outputs a signal corresponding to a stroke amount of the brake pedal to an electronic control unit. The reaction force generator has one end connected to the brake pedal and the other end connected to the housing so as to generate a reaction force against a depression force applied to the brake pedal by a driver. The reaction force changing mechanism generates a reaction force against a depression force applied to the brake pedal by the driver, and is able to change a magnitude of the reaction force in advance according to the driver.

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.

A first tubular portion and a second tubular portion are fitted with each other to form an oil accumulation chamber. The oil accumulation chamber accumulates at least one of oil outputted from a gap between the housing and the vane rotor, and oil discharged from an oil passage communicated with the advancing chamber or the retarding chamber.

Abstract: An accelerator device includes a pedal lever, a reaction force adjuster and a controller. The pedal lever operates according to a stepping operation. The reaction force adjuster is driven by an actuator, and is capable of adjusting a reaction force that is a force in a direction of pushing back the pedal lever. The controller includes a target operation amount setting unit and a drive control unit. The target operation amount setting unit sets a target operation amount, which is an operation amount of the pedal lever according to a vehicle speed. The drive control unit controls a drive of the actuator. The controller controls the reaction force according to the target operation amount so that the operation amount of the pedal lever is within a target range when switching from an automatic drive to a manual drive.

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.
