  That is, in the third configuration example, the first position information corresponding to the beacon ID of the DSRC antenna AT is acquired each time wireless communication with the DSRC antenna AT is performed, as compared with the first configuration example and the second configuration example. Therefore, the number of communications can be reduced. For this reason, it becomes possible to reduce the burden of both the vehicle position management system 1 and the user of the vehicle using the vehicle position management system 1.

  As described above, according to the present embodiment, it is possible to provide a vehicle position management system that can grasp the exact position of the vehicle.

  In addition, although some embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
