車の定速走行制御装置。 The vehicle has an actuator for operating a throttle valve of an engine, an actuator for changing gears of a transmission, and a constant speed running set means for causing constant speed running at a set vehicle speed. A constant speed cruise control device for an automobile that controls each of the actuators described above to maintain a set vehicle speed when the vehicle is set to a high speed cruise, and prohibits downshifting of the gear stage for a predetermined period of time when the constant speed cruise is set during normal driving. On the other hand, a constant speed cruise control device for a motor vehicle is provided with a control means for immediately downshifting the gear position or preventing an upshift when the constant speed cruise is set during high-load operation.
