Claim Text:
1. A method for controlling a haptic accelerator pedal in a motor vehicle comprising: determining a current rate of change of a position of a pedal lever of the haptic accelerator pedal when the pedal lever is moved in an activation direction, the activation direction being a direction that causes an acceleration of the motor vehicle; detecting if an activation condition occurs; comparing the determined current rate of change of the pedal lever with a predefined limiting value for the rate of change of the pedal lever; and activating an actuator of the haptic accelerator pedal only if (i) the activation condition is detected and (ii) the determined current rate of change of the pedal lever is lower than the predefined limiting value for the rate of change of the pedal, operating the actuator to apply an opposing force counter to the activation direction to generate a haptically perceptible signal if the actuator is activated, wherein the predefined limiting value for the rate of change of the pedal lever is dependent on at least one of (i) the current position of the pedal lever and (ii) a position of the actuator.
