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. |
