Abstract

A vehicular communication apparatus communicably connected to a portable communication terminal, includes: an information acquisition device that acquires facility information about a facility from the portable communication terminal; an information storage device that controls a storage to store the facility information in association with the portable communication terminal; and an information display device that controls a display to display the facility information stored in the storage when the portable communication terminal providing the facility information is reconnected to the vehicular communication apparatus, and that controls the display not to display the facility information stored in the storage when a new portable communication terminal different from the portable communication terminal providing the facility information is connected to the vehicular communication apparatus.

Claims

1. A vehicular communication apparatus communicably connected to a portable communication terminal, comprising:

an information acquisition device that acquires facility information about a facility from the portable communication terminal;

an information storage device that controls a storage to store the facility information in association with the portable communication terminal; and

an information display device that controls a display to display the facility information stored in the storage when the portable communication terminal providing the facility information is reconnected to the vehicular communication apparatus, and that controls the display not to display the facility information stored in the storage when a new portable communication terminal different from the portable communication terminal providing the facility information is connected to the vehicular communication apparatus.

2. The vehicular communication apparatus according to claim 1,

wherein the information acquisition device controls the storage to store the facility information in association with identification information of the portable communication terminal,

wherein the information display device determines whether a connected portable communication terminal has identification information corresponding to the identification information stored in the storage,

wherein the information display device controls the display to display the facility information stored in the storage when the connected portable communication terminal has identification information corresponding to the identification information stored in the storage, and

wherein the information display device controls the display not to display the facility information stored in the storage when the connected portable communication terminal has new identification information different from the identification information stored in the storage.

3. The vehicular communication apparatus according to claim 1

wherein the information storage device controls the storage to store the facility information, which is acquired by the information acquisition device from only one portable communication terminal,

the vehicular communication apparatus further comprising:

an information update device that updates the facility information stored in the storage; and

an information update allowance device that allows and disallows the information update device to update the facility information,

wherein, when the new portable communication terminal different from the portable communication terminal providing the facility information is connected to the vehicular communication apparatus, the information update allowance device allows the information update device to update the facility information so that the information acquisition device acquires new facility information from the new portable communication terminal, and the information update device updates the facility information stored in the storage to the new facility information acquired from the new portable communication terminal.

4. The vehicular communication apparatus according to claim 1,

wherein the information acquisition device acquires the facility information from the portable communication terminal via a short range wireless communication.

5. A vehicular communication system comprising:

a portable communication terminal; and

a vehicular communication apparatus communicably connected to the portable communication terminal,

wherein the portable communication terminal includes;

a facility information holding device that acquires facility information about a facility from an external information source and holds the facility information; and

a facility information transmission device that transmits the facility information to the vehicular communication apparatus, and

wherein the vehicular communication apparatus includes;

an information acquisition device that acquires the facility information from the portable communication terminal;

an information storage device that controls a storage to store the facility information in association with the portable communication terminal; and

an information display device that controls a display to display the facility information stored in the storage when the portable communication terminal providing the facility information is reconnected to the vehicular communication apparatus, and that controls the display not to display the facility information stored in the storage when a new portable communication terminal different from the portable communication terminal providing the facility information is connected to the vehicular communication apparatus.

6. The vehicular communication system according to claim 5,

wherein the facility information holding device continues to hold the facility information acquired from the external information source even after the facility information transmission device transmits the facility information to the vehicular communication apparatus.
