Claim:
1. An electronic throttle pedal assembly for use with a vehicle producing hysteresis, the assembly comprising: a housing having a first surface with an angled wall portion and a second surface having a generally planner portion; a pedal arm pivotally connected to the housing, the pedal arm having an outer surface, the outer surface having a generally circumferential shape; a hysteresis subassembly mounted to the housing, the hysteresis subassembly having a friction shoe and a spring carrier both mounted to the housing, the spring carrier having a rounded protrusion extending towards a free end of the pedal arm, the friction shoe having an arcuate indentation configured to receive the spring carrier rounded protrusion, the spring carrier configured to slide along the angled wall portion, the outer surface of the pedal arm in contact with an outer surface of the friction shoe, together the friction shoe and the spring carrier move as a single unit to prevent relative rotation of the spring carrier with respect to the movement of one another, the hysteresis subassembly having at least one spring mounted between the spring carrier and the pedal arm; wherein as the pedal arm is depressed, the at least one spring displaces the spring carrier along the along the angled wall portion which in turn pushes the friction shoe against the pedal arm as the pedal arm continues to rotate thereby creating friction and thus creating hysteresis between the angled wall portion and the spring carrier and between the friction shoe and the pedal arm.
