ABSTRACT:
An electronic adjustable control pedal assembly for a motor vehicle including a carrier, a guide rod adapted to be secured to the dash panel of the vehicle and mounting the carrier for fore and aft movement along the guide rod, a power drive operative to move the carrier along the guide rod, and a pedal structure including a pedal arm pivotally mounted on the carrier and a potentiometer mounted on the carrier and operative to generate an output electrical signal proportioned to the extent of pivotal movement of the pedal arm. The pedal assembly further includes a feedback apparatus for generating a feel in response to pivotal movement of the pedal arm. The feedback apparatus includes a spring to exert a spring force against the pedal arm that varies in response to the pivotal movement of the pedal arm, a first friction surface on the pedal arm, and a second friction surface on the spring for wiping coaction with the first friction surface in response to the pivotal movement of the pedal arm to provide a hysteresis effect for the pedal assembly.
