Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a follow-up running controller capable of stably effecting follow-up running while reducing the operational burdens on a driver in a traffic jam. SOLUTION: A traffic-jam follow-up ECU 10 effects automatic steering control by detecting a route to take on the basis of white lines detected by an image ECU 12, the current location obtained by a differential global-positioning system(DGPS) 14 and map information from a map database 16, and effects automatic follow-up running control on the basis of an inter-vehicle distance obtained by an inter-vehicle distance sensor 18 and a speed obtained by a speed sensor 20. When the inter-vehicle distance becomes larger than a predetermined value in the follow-up running, the automatic follow-up running control once switches the follow-up running over to constant-speed running while not immediately canceling it. When the inter-vehicle distance does not thereafter become smaller in a predetermined period of time, the automatic follow-up running control is then automatically canceled. On the other hand, when the inter-vehicle distance that has once become larger than the predetermined value becomes the predetermined value or below again in the predetermined period of time, the constant-speed running reverts to the follow-up running. |
