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 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 device includes an inner housing, a pedal lever, an urging member, and an actuator. The inner housing is supported to the outer housing by a support member. The pedal lever is rotatably supported to the inner housing in response to a stepping operation. The urging member urges the pedal lever in a closing direction. The actuator can drive the inner housing in an opening and closing directions of the pedal lever.

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.
