The invention relates to the technical field of intelligent driving, in particular to an automatic driving vehicle external man-machine interaction system and method based on vehicle-road cloud collaboration, and the system comprises an automatic driving vehicle, road side equipment, a wireless communication unit and a cloud control platform. The self-driving automobile sends the motion state and position information of the automobile to the cloud control platform after networking, the roadside equipment sends sensing data, traffic information and road information to the cloud control platform after networking, and the cloud control platform processes the data information sent by the self-driving automobile and the roadside equipment. The decision information and the control instruction are fed back to the automatic driving automobile and the roadside equipment; and the wireless communication unit adopts a DSRC (Dedicated Short Range Communication) technology. According to the method, the problems that the interactive awkward situation that automatic driving automobiles and pedestrians do not know the intentions of each other in the road right fuzzy zone is solved, the visibility of an existing vehicle-mounted eHMI is low due to the influence of ambient light and weather conditions, and information transmission is possibly unclear are solved.
本发明涉及智能驾驶技术领域,尤其涉及一种基于车路云协同的自动驾驶汽车外部人机交互系统和方法,该系统包括自动驾驶汽车、路侧设备、无线通信单元以及云控平台,自动驾驶汽车联网后将车辆本身运动状态、位置信息发送至云控平台,所述路侧设备联网后将感知数据、交通信息、道路信息发送至云控平台,所述云控平台对自动驾驶汽车和路侧设备发送的数据信息进行处理,并将决策信息、控制指令反馈至自动驾驶汽车和路侧设备;所述无线通信单元采用DSRC专用短程通信技术。本发明解决了路权模糊地带自动驾驶汽车和行人互相不知道对方意图的交互窘境,以及现有车载eHMI受环境光和天气条件影响可见度低、可能发生信息传达不明确的问题。
