Abstract
In a vehicle location detecting system having a self-contained type location detecting section for determining the accumulation type location data, a satellite navigation type location detecting section for determining the satellite type location data from satellite navigation data, a synthesizing section calculates synthetic location data from the accumulation type location data and the satellite navigation type location data. An on-road location determining section determines an on-road location of the vehicle in accordance with the synthetic location data and road map data stored in a road map memory. A display sectin displays the on-road location determined by the on-road location determining section.
