Abstract:
1. An electronically controlled pedal assembly with hysteresis comprising: a mounting bracket; a pedal arm; a pedal support arm extending between said bracket and said pedal arm, wherein said pedal arm is pivotally mounted to said pedal support arm at a pedal arm pivot point using a pedal arm mounting means, and said pedal support arm is pivotally mounted to said mounting bracket at a pedal support arm pivot point using a support arm mounting means; a hysteresis generating means having a torsion spring and a friction spacer each operatively supported on said support arm mounting means and pivotable about said pedal support arm pivot point, wherein said torsion spring has a coil, and said friction spacer has a cylindrical portion and an outer helical flange that is interposed with said torsion spring coil, so that rotation of said support arm creates a frictional hysteresis force between said torsion spring coil and said friction spacer helical flange that is translated back through said pedal arm.
