The invention discloses an automatic driving vehicle ad hoc network system and method based on a DDS protocol and an LTE-V-Direct technology. The automatic driving vehicle ad hoc network system comprises an ADAS/AD domain controller, a Classis/Body/PowerTrain domain controller and an IVI/CDC domain controller. A T-BOX unit is deployed on the ADAS/AD domain controller to control a plurality of ECU units to collect vehicle information, and the vehicle information is summarized to make an automatic driving algorithm decision; when the ADAS/AD domain controller broadcasts own vehicle information, the own vehicle type and the vehicle unique identification code are packaged into a DDS message; uE (User Equipment) is deployed in the T-BOX unit, and the UE broadcasts own vehicle information through an LTE-V-Direct technology and receives real-time information broadcasted by other vehicles at the same time; the DDS message is received and analyzed, the opposite-end vehicle type and the vehicle unique identification code are extracted, the ad hoc network vehicle topology information table is established, the ad hoc network vehicle topology information table and vehicle networking within the radio frequency sight distance range form a dynamic ad hoc network, and the timeliness of real-time information sharing between vehicles is greatly improved.
本发明公开了一种基于DDS协议与LTE‑V‑Direct技术的自动驾驶车辆自组网系统及方法,包括ADAS/AD域控制器、Classis/Body/PowerTrain域控制器、IVI/CDC域控制器;ADAS/AD域控制器上部署T‑BOX单元控制多个ECU单元采集车辆信息,汇总进行自动驾驶算法决策;ADAS/AD域控制器广播自身车辆信息时,将自身车辆类型、车辆唯一标识码封装到DDS报文中;T‑BOX单元中部署用户设备UE,UE通过LTE‑V‑Direct技术广播自身车辆信息,同时接收其他车辆广播过来的实时信息;接收并解析DDS报文,提取对端车辆类型、车辆唯一标识码,建立自组网车辆拓扑信息表,与射频视距范围内的车联形成动态的自组网络,极大地提高了车辆间实时信息共享的时效性。
