Abstract

If identification information is updated periodically, there is such a problem that when another vehicle is receiving driving support based on transmitted identification information of an own vehicle, if the identification information of the own vehicle is updated, the operation of driving support using the identification information becomes unstable because another vehicle can no longer identify the own vehicle. A mobile terminal mounted on a vehicle determines whether or not transmission control of identification information is necessary after determining the possibility of identification information misuse, determining the effect by controlling transmission of identification information, and determining the magnitude of adverse influence on the safe driving support service.

Claims17

Dependent claims

A mobile terminal which is mounted on a mobile device, and which periodically transmits mobile device information including identification information for identifying a mobile device and status information indicating a status of a mobile device, and determines whether or not there is a possibility of collision or rear-end collision with another mobile device from second mobile device information, which is the mobile device information received from another mobile device, and first status information, which is the status information of the mobile device of its own, wherein

the mobile terminal:
determines whether or not there is a possibility that the mobile device of its own is tracked by another mobile device;
determines, in a case where there is a possibility of being tracked, whether or not it is effective to perform transmission control of first mobile device information, which is the mobile device information of the mobile device of its own;
determines, in a case of performing the transmission control of the first mobile device information, whether adverse influence on service being provided is large or small, depending on whether or not there is a possibility of collision or rear-end collision of the mobile device of its own with another mobile device;
and
performs the transmission control of the first mobile device information in a case where there is a possibility of being tracked, it is effective to perform the transmission control of the first mobile device information, and the adverse influence on the service is small.
