Abstract
The invention involves a low speed control system and method for automatically regulating the speed of work vehicles or equipment and, more particularly, vehicles that apply, remove or modify roadways or road markings. The system includes a controller, a speed display, at least one rotary encoder or the like, and one or more Eddy current or mechanical brakes for inhibiting motion of the vehicle at the operator's control. The brakes may be pneumatic, spring operated, Eddy current, or hydraulic that are controlled in response to feedback from the at least one rotary encoder for compliance with the preset speed on the speed display. In another embodiment, a throttle control is also provided.
