Abstract
A navigation ECU 1 retrieves stop-position data from a map data base 8, calculates a distance between a present position of a self vehicle and a stop position closest to the present position of the self vehicle, and judges whether or not the distance is within 300 m. If it is within 300 m, the ECU 1 generates a stop informing message or a slow-down warning. Further, when a distance between a present position of the self vehicle and the stop position closest to the present position is reduced to within 5 m, the ECU 1 instructs the driver of the self vehicle to cautiously look right and left.
