  • Patent number: 5521825
    Abstract: Dynamic adjustment of the impact of automotive vehicle accelerator pedal position on engine inlet air valve position in which a gain is varied in accord with vehicle speed and a limit varied in accord with vehicle speed, the gain being applied in a transfer function between sensed accelerator pedal position and desired inlet air valve position, and the limit being applied to the desired inlet air valve position, with the transfer function varying in accord with an operator selection from a set of transfer functions.

  • Patent number: 5233882
    Abstract: A remote control lever module comprises an inner shaft coaxially located inside an outer shaft. The inner and outer shafts are rotatably mounted on a support and can rotate with respect to one another. A return mechanism is engageable with the inner and outer shafts enabling forward rotation of the inner shaft to cause forward rotation of the outer shaft. The return mechanism further enables extended forward rotation of the inner shaft with respect to the outer shaft, and urges backward rotation of the inner shaft to a rearmost position. The return mechanism limits backward rotation of the inner and outer shafts beyond a nonactuating position. A force spring urges the outer shaft to the nonactuating position. Sensors produce electrical signals proportional to the angular position of the inner and outer shafts. A friction pad can be disposed between the inner shaft and support to frictionally resist rotation of the inner shaft with respect to the support.
