DEVICE FOR GENERATING AN ADDITIONAL RESTORING FORCE AT THE GAS PEDAL AND METHOD FOR THE OPERATION THEREOF

摘要

A device and method for generating an additional restoring force at the gas pedal for motor vehicles, wherein a change in position of the gas pedal relative to its initial position, brought about by a corresponding activation force counter to a restoring force, leads to an increase in the driving force of the drive engine, and when the activation force diminishes a restoring force returns the gas pedal in the direction of its initial position. An actuator element is provided which applies an additional restoring force which acts in the restoring direction of the gas pedal. For energy efficiency, the invention provides that the magnitude of the additional restoring force (F) acting on the gas pedal is configured such that the gas pedal assumes a position which moves the operating point of the drive engine into a region with a relatively high efficiency level.
