Patent ID: 7840326

Claim:
A vehicle control system comprising: absolute position detection means that detects an absolute position of a vehicle; vehicle control means that performs a vehicle control according to the absolute position of a vehicle and stored road map data; track storing means that stores the absolute position of the vehicle currently detected by the absolute position detection means while the vehicle is traveling on a same road, as current traveling track information regarding the vehicle in place of previously stored traveling track information regarding the vehicle, wherein the vehicle control means performs the vehicle control according to road conditions determined from the traveling track information previously stored by the track storing means when the vehicle traveled the same road on which the vehicle currently travels; map data storing means that stores map data indicating a road map; position-on-map determination means that determines, on the basis of the absolute position of the vehicle detected by the absolute position detection means, the position of the vehicle with reference to the road map indicated based on the map data stored in the map-data storing means, wherein the track storing means links the traveling track information to the position of the vehicle with reference to the road map determined by the position-on-map determination means and stores the traveling track information; and determination means that determines, on the basis of the position of the vehicle with reference to the road map determined from the position-on-map determination means, whether a state that requires a traveling track of the vehicle to be stored arises, wherein the track storing means stores the traveling track information when the determination means determines that the state that requires a traveling track of the vehicle to be stored arises, and wherein the determination means determines that the state that requires the traveling track of the vehicle to be stored arises, when the position of the vehicle with reference to the road map determined by the position-on-map determination means is located within a predetermined area in the road map.
