Abstract

A method and a control device for controlling a haptic acceleration pedal in a motor vehicle includes determining a foreseeable signal position in which a haptically perceivable signal is foreseeably to be generated by the acceleration pedal at a future time. The signal position is configured to be located between a rest position and a maximally actuated position within the shifting range of the pedal. While the pedal is located in a current position between the rest position and the foreseeable position, an actuator that is configured to generate a haptically perceivable signal on the acceleration pedal is arranged in such manner that the actuator is in operational connection with the acceleration pedal when the acceleration pedal has reached the foreseeable position. The configuration results in a prompt generation of a haptically perceivable signal and a reduced energy consumption for the actuator.
