Abstract
An automotive speed control system uses logic activated switches on both sides of solenoids controlling vent and vacuum valves. A vacuum solenoid is activated upon the simultaneous occurrence of an activation of a vent valve solenoid, an activation of the speed control system, and a determination that solenoid current is below a desired magnitude.
