Abstract:
1. A vehicle position detecting system comprising: in-vehicle equipment for receiving position indicating information from artificial satellites and detecting a position of a vehicle based on the position indicating information; a map data storage device for storing map data; and a present position correcting unit for matching a vehicular travel path with some road on the map data stored in the map data storage device thereby determining a corrected present position of the vehicle, wherein the in-vehicle equipment includes a radio transmitter device and a transmission control unit for controlling the radio transmitter device to transmit vehicular travel path creating information for determining the vehicular travel path of the vehicle during a predetermined information transmission period, and wherein a position correction station is provided at an external position outside of the vehicle, and includes the map data storage device, the present position correcting unit, a receiver device for receiving the vehicular travel path creating information transmitted from the in-vehicle equipment, and a vehicular travel path determining unit for determining the vehicular travel path based on the vehicular travel path creating information received by the receiver device.
