Abstract

A method for controlling a haptic accelerator pedal in a motor vehicle includes determining a current rate of change of the pedal at which a pedal lever of the pedal changes its position between a first position of rest and a second position of maximum activation when the pedal lever is moved in an activation direction. The determined current rate of change of the pedal is compared with a predefined limiting value for the rate of change of the pedal. The actuator is activated if the determined current rate of change of the pedal is lower than the limiting value for the rate of change of the pedal. The pedal is excited by means of the actuator by applying an opposing force counter to the activation direction to generate a haptically perceptible signal if the actuator is activated when an activation condition occurs.
