Beschreibung
Zusammenfassung:	A running control system for vehicles includes a control unit, a plurality of control switches for selecting various operations, a throttle actuator, and an automatic transmission having a lock-up clutch solenoid. An automatic cruise control operation and transmission control operation is performed by the output control signals from the control unit through the throttle actuator, the lock-up clutch, and the solenoids in accordance with the set conditions of the control switches and detected signals from a vehicle speed sensor and a throttle valve sensor. With this construction, when the vehicle speed is above a predetermined value and automatic cruising is instructed, the lock-up clutch is compulsorily operated and this locked up condition of the clutch is maintained during the automatic cruising condition, thus enabling improved fuel comsumption as well as power transmission efficiency.
