Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To select a proper vehicle control mode by deciding whether or not a vehicle has entered a structure wherein it is affected by a temporarily change in circumferential environment according to a road shape and the vehicle position. SOLUTION: A mode control circuit 32 when switched to a rain mode with information from a wiper driving circuit 28 judges whether or not there is a structure cutting of rain, such as a tunnel, a parking lot, and a toll gate, at the current position of the vehicle by referring to a map data base 20 and the current position recognized by GPS, etc., through a navigation ECU 18. When it is confirmed that the current position is in the structure cutting off rain, the rain mode is maintained irrelevantly to whether or not wipers are operating. Even if the wipers are off when the rain mode is already entered before the vehicle enters the rain cutting structure, the rain mode is not maintained during the passage in the building.
