Abstract
A hysteresis assembly for a pedal includes an elastic member support, two adjacent hysteresis blocks, and an elastic member connecting the elastic member support to the more distant hysteresis block. The hysteresis blocks interface at a slope. The assembly is attached at one end to a mounting bracket for the pedal via a shaft, and at the other end to the pedal arm. As the pedal is displaced, the hysteresis blocks slide relative to each other and frictionally engage the mounting bracket. The frictional force is proportional to the return force generated by the elastic member. The spring rate of the elastic member, the angle of the slope between the hysteresis blocks, and the point of attachment are determined, through analysis, to provide desired hysteresis forces (i.e., idle force, frictional force, and return force) to the pedal, thus providing the feel of a mechanical pedal in an electronic pedal.
