Method and control device for controlling foreseeable haptically perceivable signals in an acceleration pedal of a motor vehicle

摘要

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.

1. A method for controlling a haptic accelerator pedal in a motor vehicle, the accelerator pedal being configured to be moved between a position of rest and a position of maximum actuation within a movement range and being configured to be excited by an actuator to generate a haptically perceptible signal, the method comprising:
determining a predictable signal position at which the accelerator pedal is predicted to generate a haptically perceptible signal at a future time, the predictable signal position being located between the position of rest and the position of maximum actuation, and arranging the actuator, while the accelerator pedal is in a current position between the position of rest and the predictable signal position, in such a way that the actuator becomes operatively connected to the accelerator pedal when the accelerator pedal reaches the predictable signal position.
