To provide an on-vehicle 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 device mounted on a vehicle and a device provided outside the vehicle.SOLUTION: An on-vehicle wireless communication device is mounted on a vehicle and wirelessly communicates with an external device installed outside the vehicle. The on-vehicle wireless communication device determines a communication amount in an in-vehicle network provided inside the vehicle, and transmits communication amount information related to the determined communication amount to the external device. The external device compresses transmission data 2 to a size corresponding to the received communication amount information, and transmits the compressed transmission data 2 and transmission data 1 to the on-vehicle wireless communication device. The on-vehicle wireless communication device receives the data (transmission data 1 and compressed transmission data 2) transmitted from the external device.SELECTED DRAWING: Figure 5

    【課題】車両に搭載された装置及び車両外に設けられた装置の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できる車載無線通信装置、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】車載無線通信装置は車両に搭載され、車両の外部に設置された車外装置との間で無線通信を行う。車載無線通信装置は、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を判定し、判定した通信量に係る通信量情報を車外装置へ送信する。車外装置は、受信した通信量情報に応じたサイズに送信データ2を圧縮し、圧縮した送信データ2と送信データ1を車載無線通信装置に送信する。車載無線通信装置は、車外装置から送信されるデータ(送信データ1及び圧縮された送信データ2)を受信する。【選択図】図5
