Electronic pedal assembly and method for providing a tuneable hystersis force

An electronic throttle control pedal pivotally couples a lever arm to a pedal beam and biases the beam for resisting an applying force to the pedal beam and for biasing sliding surfaces together in frictional contact. A compression spring carried between a mounting bracket and the lever arm biases the pedal beam toward an idle position while at the same time causing a frictional force between the frictional surfaces, such that displacing the pedal beam with an applying force compresses the spring which increases a frictional force between the friction surfaces with an increasing displacement of the pedal beam distal end, and reducing the displacement through a retracting force on the pedal beam distal end expands the compression spring and returns the pedal beam to the idle position through a hysteresis force response for the pedal beam displacement. The hysteresis may be tuned by modifying element dimensions of the pedal.
