Abstract
An automatic travel guiding device is a combination of a navigation control unit and automatic travel control unit that judges the position of a vehicle on a travelling road on the basis of sensed circumstances of the road extending ahead of the vehicle and correcting a current position of the vehicle to a corresponding position on the road map. The device includes means for correcting road circumstances on the basis of road data read from map-information storage medium according to the current position of the vehicle to correlatively increase both the current position accuracy and the travel control accuracy according to travel guiding instruction for following a target course preset on a road map by sensing actual road conditions and to realize automatic travel control at an increased accuracy.
