1. A vehicle communication device comprising:
an access point communication unit that is mounted on an own-vehicle and that receives, from a communication relay access point, own-vehicle access point information needed for wirelessly connecting to the communication relay access point at a traveling position of the own-vehicle, the access point information includes at least one of a service set identifier, a password, a security method, and a frequency;
a position information acquisition unit that acquires own-vehicle position information indicating the traveling position of the own-vehicle when the own-vehicle access point information is received by the access point communication unit;
a vehicle-to-vehicle communication unit that receives, from an other-vehicle in vicinity, other-vehicle access point information needed for wirelessly connecting to a communication relay access point at a traveling position of the other-vehicle and other-vehicle position information indicating the traveling position of the other-vehicle when the other-vehicle access point information is received; and
a controller that creates access point integrated information in which the own-vehicle access point information and the other-vehicle access point information are integrated with each other, wherein
the vehicle-to-vehicle communication unit receives, in real time from the other-vehicle, the other-vehicle access point information regarding the communication relay access point indicating a relatively high reception strength in the other-vehicle at a specific time and the other-vehicle position information while the own-vehicle is traveling,
the controller creates the access point integrated information at the specific time in which the other-vehicle access point information received in real time from the other-vehicle at the specific time, the other-vehicle position information received in real time from the other-vehicle at the specific time, the own-vehicle access point information of the communication relay access point indicating a relatively high reception strength, the own-vehicle access point information being received by the access point communication unit at the specific time, and the own-vehicle position information acquired by the position information acquisition unit at the specific time, are integrated with each other within a predetermined integrated range,
the vehicle-to-vehicle communication unit further receives, in real time from the other-vehicle, complementary information that includes access point information of the communication relay access point that the other-vehicle cannot receive at the traveling position of the other-vehicle, which is the access point information of the communication relay access point that cannot be directly received by the vehicle-to-vehicle communication unit but can be received by another other-vehicle at the specific time at the traveling position of the another other-vehicle,
the controller creates complemented access point integrated information in which the access point integrated information is complemented with the complementary information at the specific time received from the other-vehicle, the complemented access point integrated information includes access point information about a plurality of different communication relay access points,
the vehicle-to-vehicle communication unit transmits, in real time, the complemented access point integrated information at a specific time created by the controller to the other-vehicle in vicinity, and
the vehicle communication device of the own-vehicle creates the complemented access point integrated information in which un-complemented access point integrated information is complemented by using the complemented access point integrated information created by the vehicle communication device of the other-vehicle, as the complementary information, and transmits the complemented access point integrated information created by the vehicle communication device of the own-vehicle to the vehicle communication device of the other-vehicle, as the complementary information.
