In a vehicle communication device, a vehicle-to-vehicle communication unit receives from an other-vehicle in real time, complementary information that includes AP information that the other-vehicle cannot receive from an access point at a traveling position of the other-vehicle, the AP information being information possessed by another other-vehicle and that cannot be directly received by the vehicle-to-vehicle communication unit. Based on the complementary information received from the other-vehicle at a specific time, a controller creates complemented own-vehicle AP integrated information in which AP information that is included in an integrated range and is different from the AP information of own-vehicle AP integrated information at the specific time, is complemented. The vehicle-to-vehicle communication unit transmits the complemented own-vehicle AP integrated information at the specific time created by the controller to the other-vehicle in vicinity in real time.

Vehicle communication device and vehicle communication system

A vehicle communication device includes a vehicle-to-vehicle communication unit, an information extraction unit, and a Wi-Fi module. The vehicle-to-vehicle communication unit is mounted on an own vehicle and receives AP information required for wireless connection to an access point for communication relay from another vehicle in the vicinity. The information extraction unit extracts, from vehicle-to-vehicle AP information, which is AP information received from the other vehicle in the vicinity by the vehicle-to-vehicle communication unit, connected AP information, which is AP information received from the other vehicle in front in a traveling direction of the own vehicle and AP information of the access point to which the other vehicle in front is being connected. The Wi-Fi module wirelessly connects to the access point based on the connected AP information extracted by the information extraction unit.
