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.

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.

A vehicle is provided. The vehicle includes an electronic control unit and a pedal assembly. The electronic control unit selectively switches between a powered off state and a powered on state. The pedal assembly includes pedal arm, a target, and a switch. The pedal arm moves between a plurality of positions. The target moves with the movement of the pedal arm. The target generates a magnetic field strength. The switch activates when the magnetic field strength of the target exceeds a predetermined threshold. When the switch activates, a signal is sent to the electronic control unit to activate the electronic control unit from the powered off state to the powered on state.

A vehicle pedal emulator assembly comprising a housing and a sleeve both defining an interior cavity. The sleeve is adapted for sliding movement in the interior cavity of the housing. Respective first, second, third, and fourth springs located in opposed ends of the interior cavity of the housing are compressible in parallel in response to the sliding movement of the sleeve in the interior cavity of the housing. The first and second springs surround the shaft and extend between one end of the housing and one end of the shaft. The third and fourth springs extend between one end of the sleeve and the other end of the sleeve. The combination of an inductive sensor and a Hall Effect sensor are adapted for measurement of the position of the sleeve relative to the housing.

A brake pedal assembly comprising a pedal and a pedal resistance force member operably coupled to the pedal. A damper pedal resistance force module defines an interior fluid-filled cavity. A shaft extends through the damper module and includes a piston mounted thereon and moveable through the fluid-filled cavity to generate a damper resistance force. A spring pedal resistance force module is adapted to generate a spring pedal resistance force. A pedal force sensing module is mounted to the pedal resistance force member. A pedal position sensor is mounted to the pedal resistance force member. A pedal force sensor is mounted to the pedal resistance force member.

A pedal device comprises a brake pedal, an accelerator pedal, a support member and an adjusting device. The brake pedal is operated to be depressed by a leg of a passenger, and an operation amount of a depressing operation of the brake pedal is transmitted as an electrical signal. The accelerator pedal is operated to be depressed by a leg of the passenger, and an operation amount of a depressing operation of the accelerator pedal is transmitted as an electrical signal. The support member is connected with the brake pedal and the accelerator pedal, respectively, to support the brake pedal and the accelerator pedal in a rotatable manner. The adjusting device adjusts a position or a posture of the pedal unit including the brake pedal, the accelerator pedal, and the support member.

A pedal-side rotating member is composed of a boss portion rotatably supported by a pedal shaft, a spring holding portion for holding one end of a return spring, a stopper arm being operatively in contact with an inner wall surface of a supporting body, and a mechanically-weaker portion, wherein the boss portion, the spring holding portion, the stopper arm and the mechanically-weaker portion are integrally formed as one unit. The spring holding portion is so configured as to be broken away from the boss portion at the mechanically-weaker portion, if an acting force larger than a predetermined value is applied to the stopper arm when the rotating member is rotated in a direction to an acceleration fully-closed position. A broken piece is held at a position inside of the supporting body, so that rotation of the boss portion is not adversely affected by the broken piece.

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.

An organ-type electronic pedal apparatus includes a high-load spring module and a hysteresis lever and configured for tuning a pedal effort, a stroke, and a hysteretic force, which are required to vary depending on the types of vehicles, by changing components of the hysteresis lever, as necessary.
