Abstract
Lane travel limit zones (between a lane route deviation point and a first lane change limit point and between the lane route deviation point and a second lane change limit point), in which a lane change to a route is prohibited, are set according to the lane. If a vehicle may enter a set lane travel limit zone, a guide is provided to prompt the vehicle to make a lane change or maintain the traveling lane, according to the vehicle position and the lane on which the vehicle is traveling. To set lane travel limit zones, the lane route deviation point, which is an end point of a lane on which the vehicle can travel, the first and second lane route deviation points, which are limit points to assure that the vehicle completes a lane change before reaching the lane route deviation point, are calculated.
