ABSTRACT:
Accelerator/decelerator pedal and systems having a foot-operated pedal assembly to accelerate or decelerate vehicle engine speed and/or output on a temporary basis to override a hand lever set throttle position. The pedal and systems herein disclosed possess a double-acting spring linkage to absorb override movement of the foot pedal during such temporary acceleration or deceleration and to re-establish the original set hand throttle speed upon cessation of the override mode. An anti-feedback device prevents the throttle set position from being altered during acceleration or deceleration of engine speed and/or output.
