Description

  • The The invention relates to an accelerator pedal module and an accelerator pedal module full load indicator according to the generic terms of the independent Claims.
  • It is known to provide accelerator pedal modules with a full-load indicator. Such a full-load indicator, for example a so-called kickdown catch, is necessary for the reliable operation of an automatic transmission in combination with a cruise control and / or a speed limitation device. Thus, starting from a certain pedal travel, an electric signal is generated for the kickdown detent, which informs the driver as a tactile, abruptly increasing resistance as soon as this pedal travel is covered. Thus, it is known to arrange a magnetic kick-down notch with return spring and magnet arrangement as an additional component of an accelerator pedal module below the pedal. Such full-load indicators are usually expensive and a significant cost factor. Such a kickdown detent is for example from the DE 102 12 904 A1 known.
  • Of the Invention is based on the object, an accelerator pedal module with a simplified and cost-effective Full load indicator indicate at a full load position of the pedal another actuation of the Pedals a tangible increased Resists resistance. Furthermore, an accelerator pedal module full load indicator to be specified.
  • The The object is achieved by the Features the independent claims solved. Cheap designs and advantages of the invention are the description as well as the other claims refer to.
  • at an accelerator pedal module according to the invention with a pedal and a reset device for the pedal is the reset device locked in full load position of the pedal with a full load indicator. this makes possible the integration of the full load indicator into the module, so no separate item outside a housing the accelerator pedal module is necessary. Furthermore, the arrangement saves space and lets to perform with weight advantage.
  • is the full-load indicator band-shaped with a crooked Contour formed, can for the driver with a very simple design a reliable, perceptible perceptible Display of the full load with appropriate pedal position done.
  • One abruptly increased Resistance can be opposed to the pedal movement when the full load indicator towards its free end on its concave inner surface Step to a center of curvature towards. The pedal can interact without the full load indicator a pedal travel from an idle position to a position travel to a drive motor with a high power requirement, to a corresponding interaction element, preferably a Driver of the restoring device, at the level of the full load indicator nudge can. If the pedal continues to increase in the same direction Power demand moves, complicates the full load indicator his area beyond the stage a movement of the pedal. Of the Driver feels an abruptly increasing resistance, which he, for example, as a leap in power perceives the operator of the pedal and who indicates to him that he Full throttle there.
  • is the full load indicator together with the return device in one casing integrated, lets to be a compact, easy-to-install module. A Installation of a separate kickdown latch can be omitted. This saves Costs as well as weight.
  • Lies the reset device with a pivotally movable driver at least near the full load position on the full load indicator, can by latching the driver with the full load indicator a very simple and reliable device be created with the further pedal movement resistance is opposed. At the same time, the reset device ensures that the pedal turns off as the load on the driver's foot decreases can solve the contact with the full load indicator.
  • Preferably is the full-load indicator in its contour to a movement curve adapted to the driver. This allows existing space in the casing the accelerator pedal module can be used without increasing the accelerator pedal module.
  • A particularly cost-effective and weight-saving design is possible when the full load indicator Made of plastic. Particularly preferred is the full load indicator designed as a spring plate. This allows a particularly simple Geometry and adaptation both to the housing contour and to the pivoting movement of the driver. Optionally, the full load indicator can be used as a roll Compression spring or as a so-called Kraller formed with a spring be.
  • The accelerator pedal full-load indicator according to the invention for producing a tactile mechanical resistance in a full load position of a pedal has a band-shaped main body with a curvature along its length extension. Preferably, at a free end in the assembled state, a step is arranged so that the end is thickened. It is favorable if the curvature of the full-load indicator increases from the free end.
  • in the Following is the invention with reference to a described in the drawing embodiment explained in more detail. The The drawing, the description and the claims contain numerous features in combination, which the skilled person expediently consider individually and sum up to meaningful further combinations.
