PROBLEM TO BE SOLVED: To improve the accuracy of timing for executing vehicle control. SOLUTION: A navigation system stores information for control for being used for vehicle control performed on a road (leaving road of intersection) of a section from an intersection to the next intersection in a link unit. Concretely, the navigation system detects a stop sign line that a vehicle travels through when the vehicle comes into an intersection as a control end point, and detects an intersection point that the vehicle travels through when the vehicle leaves the intersection point as a control start point. The navigation system stores a travel track based on a vehicle absolute position as information for control with the control start point as a start point and the control end point as an end point and outputs the information for control to a vehicle control part when the vehicle travels on a road whose information for road has been already stored. Consequently, the vehicle control part can achieve highly accurate vehicle control based on an actual road shape. Especially, by outputting passing timing when the vehicle travels through the control start point and the control end point to the vehicle control part, the accuracy of the timing of vehicle control can be enhanced.
