A system for controlling a vehicle fitted with electrical controls, the control system includes a handgrip mounted on a shaft and fitted with a position sensor and with a return spring which is fixed by one end to the handgrip so as to generate a return moment that opposes the twisting of the handgrip. The system includes at least one actuator able to move a cam mounted on the shaft and able to: modify the preload of the return spring according to the position of the cam to which the other end of the return spring is fixed, and/or modify the travel of the handgrip by collaborating with an end stop of the handgrip, the end stop coming into contact with a cam at the end of the travel.

An accelerator pedal for a vehicle, which has a hysteresis generation structure, is provided. The accelerator pedal includes: a housing including a pivot shaft; a pedal unit which is rotatably connected to the pivot shaft and has a pivot hole; a hysteresis generation member which receives a portion of the pedal unit and has an extension part that hits against the pedal unit and rotating in a direction in which the pedal unit rotates, when the pedal unit is rotated by applying a force to the pedal unit; and an elastic member which has an end connected to the extension part of the hysteresis generation member and applies an elastic force to the hysteresis generation member. When the force applied to the pedal unit is removed, the hysteresis generation member rotates in an opposite direction to the rotation direction of the pedal unit.

An accelerator pedal for a vehicle, which has a hysteresis generation structure, may be provided. The accelerator pedal includes: a housing which includes a pivot shaft; a pedal unit which includes a hinge connected pivotably to the housing; a first spring which is positioned under the pedal unit in such a manner as to be pressed downward when the pedal unit is pivoted; a friction member which is pivotably connected to the housing and contacts the hinge; a second spring which provides an elastic force to the friction member; and a force transmitting member which is positioned between the friction member and the second spring and transmits the elastic force of the second spring to the friction member.

This power transmission device includes a motor, a worm connected to a rotating shaft of the motor, and a worm wheel engaged with the worm and disposed at an operation pedal side with respect to the worm, wherein a biasing member which biases the motor in a direction in which the worm and the worm wheel come in contact with each other when the motor is driven is disposed between the motor and a housing.

A pedal assembly for a vehicle that includes a foot pad, a pedal base, a flexible hinge that couples the foot pad to a first end of the pedal base, a sensor configured to sense a force exerted on the foot pad, and an electronic processor connected to the sensor. The electronic processor is configured to generate an output signal for controlling the vehicle based on a signal generated by the sensor and a model that defines a mechanical hysteresis effect. Another pedal assembly includes a prismatic joint that couples the foot pad to the pedal base. The prismatic joint enables linear displacement of the foot pad relative to the pedal base when a force is exerted on the foot pad.

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 unlocks the pedal lever when an approaching object from behind is detected during a travel of a vehicle in the locked state.

An accelerator pedal for a vehicle, which has a hysteresis generation structure may be provided. The accelerator pedal for a vehicle according to the embodiment of the present invention includes: a housing; a cylindrical hinge which is connected to the housing; a main pedal arm which is coupled to one side of the hinge and rotates in a first direction in close contact with a first action point of the one side of the hinge when a predetermined force is applied; an auxiliary pedal arm which is coupled to the other side of the hinge and rotates in a second direction in close contact with a second action point of the other side of the hinge by an elastic force when the force applied to the main pedal arm is removed; and a spring which is coupled to a bottom of one end of the auxiliary pedal arm and applies the elastic force to the auxiliary pedal arm.

An automotive vehicle includes a body having a passenger compartment and a movable pedal housing which is movable between first and second positions with respect to the passenger compartment. The vehicle additionally includes at least one pedal which is operably coupled to the housing and actuatable by an occupant. The vehicle also includes an actuator operably coupled to the pedal and to the housing. The actuator is configured to apply a resistive force to the pedal to resist motion of the pedal. The actuator is configured to selectively move the housing between the first and second positions. The vehicle further includes at least one controller configured to, in response to satisfaction of a first operating condition, control the actuator to move the pedal housing to the first position, and, in response to satisfaction of a second operating condition, control the actuator to move the pedal housing to the second position.

An active accelerator pedal for a vehicle includes a pedal position sensor configured to detect a position of a pedal lever of the active accelerator pedal and to convert the position into a pedal position signal. The active accelerator pedal further includes an actuator configured to output haptic feedback to the pedal lever. The active accelerator pedal further includes an actuator controller configured to control the actuator. The pedal position sensor is configured to transmit pedal position signals to a central engine controller of the vehicle the engine controller is configured to control drive of the vehicle using the central engine controller, and the actuator controller is configured to receive a pedal position signal from the pedal position sensor.

A vehicle control system is provided, which includes a steering angle detector configured to detect a steering angle of a steering wheel by the operator, the steering wheel is mounted on the vehicle, a speed detector configured to detect a traveling speed of the vehicle, a reaction-force generator configured to generate a reaction force of the steering wheel, and a controller. The controller includes a processor configured to execute a lateral acceleration calculating module to calculate a lateral acceleration based on the traveling speed and the steering angle, a rigidity characteristic setting module to set the reaction force so that a rigidity value that is a ratio of the reaction force to the steering angle increases as the lateral acceleration increases, and a reaction-force control module to control the reaction-force generator so that the reaction force becomes the reaction-force value set by the rigidity characteristic setting module.
