<p>A vehicular speed control system, comprising, phasing means (98) for providing a sequence of electrical phase steps in response to a comparison of actual vehicle speed to a desired vehicle speed, a stepper motor (12) coupled to a pinion shaft (16) for rotating said pinion shaft (16) by discrete phase steps in response to said phasing means (98), gear transfer means (22) having a plurality of gear teeth for rotatably coupling to said pinion shaft with minimal slack between said gear teeth of said first gear transfer means and gear teeth of said pinion shaft, and transfer means (44, 46,58) coupled between said gear transfer means (22) and the throttle for displacing the throttle in response to rotational movement of said stepper motor (12).</p> |
