PROBLEM TO BE SOLVED: To eliminate troublesome operation to return to automatic speed control by furnishing an automatic returning means to automatically return to an automatic speed control state in the case when specified drive to temporarily release automatic speed control is a transient demand of a driver by judging whether it is the transient demand or not. SOLUTION: Cruise control in a computer 4 is temporarily released in the case when a brake switch 13a is switched on at the time when a car-to-car distance control state is carried out. At this time, when a main switch 12a of a cruise control switch 12 is kept on, whether an accelerator switch 13b is in an ON state or not is judged, and when a judgement result is ON, whether a preceding car is detected or not is judged by information from a scanning distance measure 6-Thereafter, when the accelerator switch 13b is switched off, if the preceding car is detected, it is automatically returned to car-to-car distance control, and if the preceding car is not detected, it is returned to an automatic cruise state. |
