Abstract

A pedal system includes a housing, a pedal lever pivoted to the housing for rotation, and a hysteresis mechanism located above the pivot axis when mounted in a vehicle so that it is positioned in a protected position from environmental dirt and debris, and further is positioned in a more open region less subject to conflicting special requirements within the vehicle. The housing defines a closed end and an open end. The pedal lever is adapted to fit into the housing with the hysteresis mechanism already mounted on a free end of the pedal lever. A pivot pin extends through side walls of the housing and also through the pedal lever to retain the pedal lever in the housing, and is accessible for attachment of an electrical sensor for sensing angular position of the pedal. In one form, the hysteresis mechanism includes a pedal-mounted rub pad and a mating hysteresis-lever-mounted rub pad, at least one being a lubricant-impregnated material, both including angled mating surfaces for providing sliding hysteresis friction.
