ABSTRACT:
An electronically controlled pedal assembly with hysteresis includes a housing having a front wall and an arcuate friction wall having a radius of curvature centered on a pedal arm pivot point and extending from an edge of the front wall. The pedal assembly also includes a pedal arm rotatably supported at the pedal arm pivot point by a mounting means operatively connected to the housing, and a hysteresis generating means pivotally mounted to the pedal arm. The pedal assembly further includes a spring positioned between the housing and the hysteresis generating means, such that the spring biases the hysteresis generating means against the housing, so that depression of the pedal arm compresses the spring while generating an increasing frictional hysteresis force between the arcuate friction wall and the hysteresis generating means that is translated back through the pedal arm, and release of the pedal arm reduces the frictional hysteresis force.
