Vehicle position information providing devices, methods, and programs
First Claim
1. A vehicle position information providing device, comprising:
- a communication device that communicates over a mobile phone network;
a controller that;
acquires a first current position of a vehicle based on a radio signal received from a GPS satellite;
acquires a second current position of the vehicle based on a signal received by the communication device;
determines whether the first current position and the second current position coincide; and
if the first current position and the second current position do not coincide, causes the communication device to transmit information relating to the first current position to an information center.

Abstract
Vehicle position information providing devices, methods, and programs acquire a first current position of a vehicle based on a radio signal received from a GPS satellite and acquire a second current position of the vehicle based on a signal received by a communication device that communicates over a mobile phone network. The devices, methods, and programs determine whether the first current position and the second current position coincide. If the first current position and the second current position do not coincide, the devices, methods, and programs cause the communication device to transmit information relating to the first current position to an information center.
