  • the invention is based, an accelerator pedal module with the task. to provide a simplified and inexpensive full-load indicator which, when the pedal is in a full-load position, opposes further actuation of the pedal to a noticeably increased resistance. Furthermore, an accelerator pedal module full load indicator should be given.
  • the object is achieved by the features of the independent claims. Favorable configurations and advantages of the invention can be found in the description and the further claims.
  • the reset device can be locked in the full load position of the pedal with a full load indicator. This enables the full-load indicator to be integrated into the module, so that no separate element outside a housing of the accelerator pedal module is necessary. Furthermore, the arrangement saves space and can be carried out with a weight advantage.
  • the full-load indicator is designed in the form of a band with a curved contour, the driver can be provided with a very simple design with a reliable, tangible display of the full load with the corresponding pedal position.
  • An abruptly increased resistance can be opposed to the pedal movement if the full-load indicator has a step toward its center of curvature on its concave inner surface towards its free end. Without interacting with the full-load indicator, the pedal can cover a pedal travel from an idling position to a position with high power requirements on a drive motor until a corresponding interaction element, preferably a driver of the reset device, can hit the stage of the full-load indicator. If the pedal is moved further in the same direction of increasing power demand, the full load indicator with its area beyond the step makes it difficult to move the pedal. The driver feels an abruptly increasing resistance, which he calls, for example Perceives the operator's power jump and indicates that he is at full throttle.

  • the resetting device with a pivotably movable driver lies at least near the full-load position on the full-load indicator, a very simple and reliable device can be created by latching the driver with the full-load indicator, with which further pedal movement is opposed to resistance. At the same time, the reset device ensures that the pedal can release itself from contact with the full-load indicator when the load on the driver's foot decreases.
  • the contour of the full-load indicator is preferably adapted to a movement curve of the driver.

  • the accelerator pedal module full load indicator according to the invention for generating a tactile mechanical resistance in a full load position of a pedal has a band-shaped base body with a curvature along its longitudinal extent.
