A brake device for a vehicle includes: a brake pedal having a pedal portion and a lever portion that rotates about a rotation axis when the pedal portion is operated; a housing that rotatably supports the lever portion; and a plate member configured to generate a reaction force with respect to the lever portion in response to a stroke amount of the brake pedal. The plate member has a longitudinal surface defined by a side extending in a longitudinal direction of the plate member and a side extending in a width direction of the plate member. The longitudinal surface is arranged so as to face the lever portion. When the pedal portion is operated, the plate member is bent to generate the reaction force.

A brake device includes: a brake pedal including a pedal and a lever that rotates about a rotation axis when the pedal is operated; a housing that rotatably supports the lever; a reaction force generator that generates a reaction force to the lever in accordance with a stroke amount of the brake pedal by receiving a force from the lever when the brake pedal is operated; a deformation member including a deformation portion that is deformed by a force received from the lever when the brake pedal is operated in a state where the reaction force generated by the reaction force generator is generated; and a stroke sensor that outputs a signal corresponding to the stroke amount and outputs a value indicating that operation of the brake pedal is abnormal and instructing execution of control for stopping a vehicle when the deformation portion is deformed.

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.

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.

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.

A foldable pedal apparatus for vehicles is provided in which pedal pads are rotated rearwards from a footrest panel and thus enter a pop-up state to be manipulable by a driver in a manual driving mode in which the driver directly drives a vehicle. The pedal pads are rotated forwards maximally close to the front surface of the footrest panel and thus enter a hidden state without exposure to be nonmanipulable by the driver in an autonomous driving situation.

A foldable pedal apparatus for a vehicle includes pedal assemblies including pedal arms and pedal pads that are rotated rearwards and are thus popped up to a driver so as to be operated by the driver in a manual driving mode in which the driver directly drives a vehicle. Also, the pedal assemblies including the pedal arms and the pedal pads may be rotated forwards and upwards, so as to be located close to a front surface of a footrest panel and thus enter a hidden state in which exposure of the pedal assemblies to the driver is interrupted so as not to be operated by the driver in an autonomous driving situation.

A pedal assembly includes a housing, a spring arm member, a pedal arm, a spring carrier, and a spring guide member. The spring arm member is coupled to the housing. The pedal arm has a hub portion and an opposite pedal pad. The hub portion is pivotally retained in the housing by the spring arm member at the hub portion. The spring carrier is coupled to the pedal arm and to the spring arm member. The spring carrier has at least one spring positioned to provide a first pedal effort force to the pedal arm at a first amount of predetermined travel of the pedal arm. The spring guide member contacts a second at least one spring from the pedal arm when the pedal arm exceeds a second amount of predetermined travel of the pedal pad. The at least one spring provides a second pedal effort force.

A foldable pedal apparatus for a vehicle includes a misoperation prevention pad, an accelerator pedal pad and a brake pedal pad. In a manual driving mode in which a driver directly drives, the accelerator pedal pad and the brake pedal pad protrude and are exposed toward the driver and then enter into a popped-up state so that operation of the pedal pads by the driver may be performed. In an autonomous driving situation, the accelerator pedal pad and the brake pedal pad are hidden and then enter into a hidden state in which exposure toward the driver is blocked so that the operation of the accelerator pedal pad and the brake pedal pad by the driver is unable to be performed. Furthermore, the misoperation prevention pad is provided between the accelerator pedal pad and the brake pedal pad.
