Zusammenfassung: | PURPOSE:To avoid rapidly rotating an engine uselessly, by providing a restarting to detect the difference between the actual speed of a vehicle and a preset speed after the reengagement of a clutch to turn on a gate circuit to resume constant- speed movement control on the basis of a difference signal. CONSTITUTION:A differential amplifier 10 receives a vehicle speed signal SS and a present vehicle speed signal Vo stored in a memory 16 and corresponding to a preset signal ST for a constant-speed movement stored in the memory, and sends out a signal DELTAS corresponding to the difference between the signal SS, Vo. A gate circuit 11 for passing or blocking the difference signal DELTAS is driven by a drive signal DS from a first power supply unit 12. When an outomobile has begun to move uphill, the difference signal DELTAS becomes larger so that a clutch is disengaged by a gear-shifting operation. At the moment of the disengagement, a clutch switch 13 is opened to turn off the gate circuit 11 to cut off the difference signal DELTAS from an engine control system. As a result, the constant-speed movement is temporarily ceaused so that an engine is prevented from being rapidly rotated under no load. |
