A vehicle control system includes an own vehicle position calculation section that calculates an own vehicle position on a map by using a coordinate system projected by a map projection method based on conformal map projection, which has conformality and represents most regions in the world with a single system, and a vehicle control section that controls a vehicle by using the own vehicle position calculated by the own vehicle position calculation section by using the coordinate system projected by the map projection method based on conformal map projection, which has conformality and represents most regions in the world with a single system.
