1. A method of employing a vehicle speed stabilization processor for setting and canceling a cruise control system (CC) coupled thereto by operating an accelerator pedal, said processor executing the following steps:

  • (a) setting the CC at a CC engagement speed when a given vehicle speed exceeds a minimum vehicle speed and said given vehicle speed stays within predetermined boundary limits for a particular time period;

    (b) establishing a virtual pedal position that is whatever pedal position corresponds to a vehicle throttle position at said CC engagement speed;

    (c) upon setting of the CC, establishing a pedal position tolerance motion range about a current virtual pedal position within which the pedal can travel without canceling the CC;

    (d) canceling the CC when the pedal position becomes higher than an upper boundary of the pedal position tolerance motion range; and

    (e) canceling the CC when the pedal position becomes lower than a lower boundary of the pedal position tolerance motion range.
