Abstract: A driver of a vehicle applies an actuation force to an accelerator device such as an accelerator pedal or a twist-grip throttle of the vehicle to deflect the accelerator device to an actual deflection angle (?act), which is detected. A restoring force acts on the accelerator device opposite the actuation force. An electronic controller determines a nominal deflection angle (?nom) to which the accelerator device shall be deflected, based on inputs such as an actual speed of the subject vehicle, a relative speed of the subject vehicle relative to a leading vehicle driving ahead of the subject vehicle, an actual distance of the subject vehicle to the leading vehicle, and a nominal distance at which the subject vehicle shall follow the leading vehicle. The restoring force on the accelerator device is modulated as a function of the difference between the actual deflection angle (?act) and the nominal deflection angle (?nom).

Abstract: A method for operating an accelerator pedal unit for motor vehicles, wherein a change in position of the pedal plate, which is brought about by a corresponding activation force, with respect to the starting position of said pedal plate counter to a restoring force of a pedal restoring spring brings about an increase in the driving force of the drive motor of the motor vehicle, and when the activation force diminishes the restoring force of the pedal restoring spring moves the pedal plate back in the direction of its starting position, wherein an electromechanical actuator which can be actuated externally is arranged in such a way that an additional restoring force acting on the pedal plate can be set.

Abstract: An accelerator pedal unit (1) for a motor vehicle includes an accelerator pedal (11) for controlling a propelling force of a motor of the motor vehicle, and a return spring. A position change of the accelerator pedal (11) from its starting position caused by an actuating force against a restoring force exerted by the return spring results in an increase of the propelling force of the motor, and the restoring force of the return spring returns the accelerator pedal (11) toward its starting position when the actuating force subsides. A friction device (100, 200, 300, 400, 500, 600) generates a friction force that acts in addition to the restoring force. Alternatively, an electromechanical main actuator (18) produces an additional restoring force (FZusatz) that can be variably controlled using a control unit (12).

Abstract: A drive pedal unit for motor vehicles, wherein a position change of the pedal plate brought about by a corresponding actuating force, with respect to the starting position thereof against a restoring force of a restoring spring, leads to an increase of the drive force of the engine and, when the actuating force decreases, the restoring force of the restoring spring returns the pedal plate in the direction of the starting position thereof. An externally controllable electro-mechanical actuator is arranged such that an additional restoring force may be set on the pedal plate. A hysteresis of the pedal characteristic curve is produced and is independent of the additional restoring force of the electromechanical actuator. A friction surface cooperates with a friction element, wherein the friction surface is connected to the pedal plate, whilst the friction element is decoupled from the power flow between the pedal plate and the electromechanical actuator.

Abstract: A device and method for generating an additional restoring force at the gas pedal for motor vehicles, wherein a change in position of the gas pedal relative to its initial position, brought about by a corresponding activation force counter to a restoring force, leads to an increase in the driving force of the drive engine, and when the activation force diminishes a restoring force returns the gas pedal in the direction of its initial position. An actuator element is provided which applies an additional restoring force which acts in the restoring direction of the gas pedal. For energy efficiency, the invention provides that the magnitude of the additional restoring force (F) acting on the gas pedal is configured such that the gas pedal assumes a position which moves the operating point of the drive engine into a region with a relatively high efficiency level.

The electric motor includes a rotor and a stator which is arranged on the shaft of the electric motor, between the rotor and the drive disk.

Abstract: A method for regulating motor vehicle speed by a pedal system having a force resetting device, including a pedal lever with a pedal return spring which can move the pedal lever to its zero position, an electric motor pivotable about a center of rotation which, when energized, can apply a resetting force to the pedal lever in the zero position direction, a motor return spring resets the electric motor in the zero position direction of the electric motor, and a control unit for controlling the electric motor. When the electric motor is de-energized, the pedal return spring, the motor return spring and a hysteresis element generate a passive pedal characteristic curve (PPCC). The PPCC can be changed by energizing the electric motor, and is variable additively at maximum with the available torque of the electric motor and substractively in the region of the spring constant of the motor return spring.
