ABSTRACT:
A vacuum actuator for actuating the throttle valve of a vehicle is driven by a surge tank via three valves which are actuated by their respective solenoids. These solenoids are energized by their respective driver circuits. The input signal applied to each solenoid is compared with the output signal delivered from the solenoid by a comparator. The comparators for the solenoids are incorporated in a microcomputer. If any one of the comparators indicates disagreement between its two input signals, and if this disagreement persists for a given period, then the microcomputer deenergizes the corresponding solenoid. A timer for measuring the duration of the disagreement is also incorporated in the microcomputer. For example, the invention can be employed in a velocity-sustaining device for a vehicle.
