To provide a vehicle communication device and a vehicle communication system which can share useful access point information.SOLUTION: In a vehicle communication device 1, a vehicle-to-vehicle communication unit 40 receives, from another vehicle real time, complementary information, including AP information, which is provided in the other vehicle and cannot be received by another vehicle from an access point AP at the running position of another vehicle and cannot be directly received by a vehicle-to-vehicle communication unit 40. Based on the complementary information received from another vehicle at a specific time, a control unit 50 generates complemented self-vehicle AP integral information which is included in an integral range to complement AP information different from the AP information of the self-vehicle AP integral information at the specific time. The vehicle-to-vehicle communication unit 40 transmits the complemented self-vehicle AP integral information at the specific time, which is generated by the control unit 50, to other vehicles in the periphery real time.SELECTED DRAWING: Figure 2 【課題】有用なアクセスポイント情報を共有することができる車両通信装置及び車両通信システムを提供する。【解決手段】車両通信装置１において、車車間通信部４０は、他車両が当該他車両の走行位置でアクセスポイントＡＰから受信できないＡＰ情報であって当該車車間通信部４０により直接受信できない別の他車両が有するＡＰ情報を含む補完用情報を他車両からリアルタイムで受信する。制御部５０は、他車両から受信した特定時刻における補完用情報に基づいて、統合範囲内に含まれ且つ特定時刻における自車両ＡＰ統合情報のＡＰ情報とは異なるＡＰ情報を補完した補完後の自車両ＡＰ統合情報を作成する。車車間通信部４０は、制御部５０により作成した特定時刻における補完後の自車両ＡＰ統合情報をリアルタイムで周囲の他車両に送信する。【選択図】図２
