STEWART WILLIAM S / OLDENBURG ROBERT F / KAIJALA MURRAY

A vehicle pedal assembly with a rotatable pedal. A hysteresis assembly includes a friction device and plunger, and first and second springs that are all separate and decoupled from each other and the pedal. The first spring exerts a force against the friction plunger that forces the friction device into frictional contact with the housing to generate and transfer a resistance force to the pedal. The first spring also exerts a force against the pedal when a foot force is removed from the pedal to return the pedal to idle with and without the movement of the friction device and without the force of the second spring. The second spring exerts a force against the friction device when the foot force is removed to return the pedal to idle without the force of the first spring. Barriers block the entry of debris into the housing.
