    • The present invention provides an on-vehicle communication device capable of suppressing a delay in providing information, avoiding congestion, and sufficiently securing transmission power. An on-vehicle communication device (100) according to the present invention includes communication control means (3) that controls a transmission cycle and transmission power when data is transmitted from transmitting/receiving means (2). The communication control means (3) uses own vehicle information and surrounding vehicle information to estimate a degree of risk (R) and a safe distance (Ds) of own vehicle. The communication control means (3) controls the transmission cycle of own vehicle based on a communication channel utilization rate of own vehicle, a communication channel utilization rate of a surrounding vehicle and the degree of risk (R) of own vehicle. The communication control means (3) controls the transmission power of own vehicle based on the communication channel utilization rate of own vehicle, the communication channel utilization rate of the surrounding vehicle and the safe distance (Ds).
    • 本发明提供一种车载通信装置,其能够抑制提供信息的延迟,避免拥塞并充分确保发送功率。 根据本发明的车载通信设备(100)包括当从发送/接收装置(2)发送数据时控制发送周期和发送功率的通信控制装置(3)。 通信控制装置(3)使用自己的车辆信息和周围的车辆信息来估计本车辆的风险(R)和安全距离(Ds)。 通信控制装置(3)基于本车辆的通信信道利用率,周边车辆的通信信道利用率和本车辆的风险程度(R)来控制本车辆的发送周期。 通信控制装置(3)基于本车辆的通信信道利用率,周围车辆的通信信道利用率和安全距离(Ds)来控制本车辆的发送功率。
