Provided are a wireless communication device, a wireless communication system, and a wireless communication method that are expected to suppress an increase in the amount of data transmitted and received by road-to-vehicle wireless communication. A wireless communication device according to an embodiment of the present invention is provided with a wireless communication unit that performs wireless communication with a vehicle, and a processing unit that performs processing relating to communication, the processing unit determining the amount of communication of wireless communication with one or more vehicles by means of the wireless communication unit. Communication volume information related to the determined communication volume is transmitted to the vehicle by the wireless communication unit, and data transmitted from the vehicle at a size corresponding to the transmitted communication volume information is received by the wireless communication unit. The processing unit may also receive, from the vehicle, traffic information relating to traffic of an in-vehicle network provided inside the vehicle, adjust the size of data to be transmitted to the vehicle on the basis of the received traffic information, and transmit the sized data to the vehicle via the wireless communication unit.

    提供能够期待抑制通过路车间的无线通信收发的数据量的增大的无线通信装置、无线通信系统及无线通信方法。本实施方式所涉及的无线通信装置具有进行与车辆的无线通信的无线通信部及进行通信所涉及的处理的处理部,上述处理部对通过上述无线通信部在与一个或多个车辆之间进行的无线通信的通信量进行判定,通过上述无线通信部向上述车辆发送判定出的通信量所涉及的通信量信息,通过上述无线通信部接收以与发送的上述通信量信息对应的大小从上述车辆发送的数据。也可以是,上述处理部从上述车辆接收设置于上述车辆的内部的车内网络的通信量所涉及的通信量信息,根据接收到的上述通信量信息,调整应该向上述车辆发送的数据的大小,通过上述无线通信部向上述车辆发送调整了大小的数据。
