The invention provides a communication system of an automatic driving vehicle. The system comprises a first communication system, a second communication system and a data interaction device, an automatic driving controller in the second communication system can be connected with an automatic driving detection device; therefore, the automatic driving function can be realized based on the automaticdriving controller and the automatic driving detection device, the first communication link in the first communication system is connected with the electronic control unit in a distributed connectionmode, and the original functions of the vehicle are realized through the electronic control unit. Moreover, the data transmission rate of the first communication link is lower than the data transmission rate of the second communication link, i.e., different data transmission rates are adopted for different functions, so that the timeliness of data transmission of an automatic driving function canbe ensured, and the data transmission function of an electronic control unit on the vehicle cannot be influenced.
本发明提供了一种自动驾驶车辆的通信系统,包括第一通信系统、第二通信系统和数据交互装置,第二通信系统中的自动驾驶控制器可以连接自动驾驶检测装置,从而可以基于自动驾驶控制器和自动驾驶检测装置实现自动驾驶功能,第一通信系统中的第一通信链路通过分布式连接方式连接电子控制单元,通过电子控制单元实现车辆的车辆原有功能。并且,第一通信链路的数据传输速率低于所述第二通信链路的数据传输速率,也即实现不同功能采用不同的数据传输速率,这样可以保证自动驾驶功能的数据传输的时效性,也不会影响车辆上的电子控制单元的数据传输功能。
