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 current position measured by the mobile phone network and received by the communication device, the current position measured by the mobile phone network being measured without using a radio signal received from a GPS satellite;
determines whether the first current position and the second current position coincide;
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 and the time at which the first current position was detected to an information center; and
if the first current position and the second current position coincide, prevents the communication device from transmitting information relating to the first current position and the time at which the first current position was detected 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.

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 current position measured by the mobile phone network and received by the communication device, the current position measured by the mobile phone network being measured without using a radio signal received from a GPS satellite; determines whether the first current position and the second current position coincide; 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 and the time at which the first current position was detected to an information center; and if the first current position and the second current position coincide, prevents the communication device from transmitting information relating to the first current position and the time at which the first current position was detected to an information center. - View Dependent Claims (2, 3, 4, 5)

6. A vehicle position information providing method, comprising:
-
acquiring a first current position of a vehicle based on a radio signal received from a GPS satellite; acquiring a second current position of the vehicle based on a current position measured by a mobile phone network and received by a communication device that communicates over the mobile phone network, the current position measured by the mobile phone network being measured without using a radio signal received from a GPS satellite; determining 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, causing the communication device to transmit information relating to the first current position and the time at which the first current position was detected to an information center; and if the first current position and the second current position coincide, preventing the communication device from transmitting information relating to the first current position and the time at which the first current position was detected to an information center. - View Dependent Claims (7)

8. A computer-readable storage medium storing a computer-executable program usable to provide vehicle information, the program comprising instructions that cause a computer to:
-
acquiring a first current position of a vehicle based on a radio signal received from a GPS satellite; acquire a second current position of the vehicle based on a current position measured by a mobile phone network and received by a communication device that communicates over the mobile phone network, the current being measured without using a radio signal received from a GPS satellite; 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, cause the communication device to transmit information relating to the first current position and the time at which the first current position was detected to an information center; and if the first current position and the second current position coincide, prevent the communication device from transmitting information relating to the first current position and the time at which the first current position was detected to an information center. - View Dependent Claims (9)
