To provide a wireless communication device, a wireless communication system, and a wireless communication method that can suppress an increase in the amount of data transmitted and received in wireless communication between a road and a vehicle.SOLUTION: A wireless communication device according to the present embodiment includes a wireless communication unit that wirelessly communicates with vehicles and a processing unit that performs processing related to communication. The processing unit determines a communication amount in wireless communication performed with one or more vehicles by the wireless communication unit, transmits communication amount information related to the determined communication amount to the vehicles by the wireless communication unit, and receives, by the wireless communication unit, data transmitted from the vehicles at a size corresponding to the transmitted communication amount information. The processing unit receives communication amount information about a communication amount in an in-vehicle network provided inside the vehicles from the vehicles, adjusts a size of data to be transmitted to the vehicles according to the received communication amount information, and may transmit the data whose size is adjusted to the vehicles by the wireless communication unit.SELECTED DRAWING: Figure 5

    【課題】路車間の無線通信で送受信されるデータ量の増大を抑制することが期待できる無線通信装置、無線通信システム及び無線通信方法を提供する。【解決手段】本実施の形態に係る無線通信装置は、車両との無線通信を行う無線通信部、及び、通信に係る処理を行う処理部を有する無線通信装置であって、前記処理部は、前記無線通信部により一又は複数の車両との間で行われる無線通信における通信量を判定し、判定した通信量に係る通信量情報を前記無線通信部にて前記車両へ送信し、送信した前記通信量情報に応じたサイズで前記車両から送信されるデータを前記無線通信部にて受信する。前記処理部は、前記車両の内部に設けられた車内ネットワークにおける通信量に係る通信量情報を、前記車両から受信し、受信した前記通信量情報に応じて、前記車両へ送信すべきデータのサイズを調整し、サイズを調整したデータを前記無線通信部にて前記車両へ送信してもよい。【選択図】図5
