The invention relates to the field of Internet of Vehicles, in particular to a vehicle rear-end data monitoring platform for an Internet-of-Vehicles system. A method for determining confidence and/orpriority of reported event data reported by a vehicle in an Internet-of-Vehicles system (1) is provided, the method at least comprises the steps of obtaining an event risk degree parameter corresponding to a reported event type, obtaining a historical traffic flow speed at a corresponding geographic position based on the reported geographic position, and then obtaining a speed deviation parameterbased on a deviation between a vehicle speed at a reporting moment and the historical traffic flow speed; and determining the confidence and/or priority of the reported event data at least based on the event risk parameter and the speed deviation parameter. The method may also include determining a frequency parameter based at least on the same or similar event reporting frequencies at the respective geographic locations and taking into account the frequency parameter when determining a confidence and/or priority of the reported event data. The calculation reliability of the confidence coefficient and/or priority of the vehicle report event can be improved.
本发明涉及车联网领域、尤其涉及用于车联网系统的车辆后端数据监控平台。提供了一种用于确定车联网系统(1)中车辆上报的上报事件数据的置信度和/或优先级的方法,至少包括:基获取上报事件类型对应的事件危险度参数,基于上报的地理位置获取相应地理位置处的历史车流速度,然后基于上报时刻的本车速度与历史车流速度的偏差得到速度偏差参数;至少基于事件危险度参数和速度偏差参数确定上报事件数据的置信度和/或优先级。该方法还可包括:至少基于相应地理位置处的相同或同类事件上报频次确定频次参数并在确定上报事件数据的置信度和/或优先级时还考虑频次参数。可提高车辆上报事件的置信度和/或优先级的计算可靠性。
