Abstract
A vehicle control system includes a road data memory, current position sensor that detects a current position of a vehicle and a camera that takes a picture of the road ahead of the current position. At least one indicator line such as a lane dividing line on the road is shown in the picture. The picture changes as the vehicle moves forward along the road, during which increase in width of the indicator line or increase of distance between two indicator lines may be detected. By such detection, the vehicle position with respect to the indicator line is determined, the result of which is incorporated into control operation of an automatic transmission, for example.
