The invention belongs to the technical field of automobiles, and particularly relates to a non-replaceable memory-saving automobile data recording system which comprises an automobile data recorder and a cloud server connected with the automobile data recorder. The automobile data recorder is used for collecting driving images and sending real-time driving position data to the cloud server; the cloud server receives the driving position data, calculates a road risk index of the driving position, and sends the road risk index to the driving recorder; and the automobile data recorder adjusts the resolution of the stored video according to the road risk index. The current position is determined through the automobile data recorder, the risk index of the current position is calculated through the cloud server, and the video storage resolution is adjusted according to the risk index, so that the storage space is optimized, and the problem of second leakage occurring when the storage space is saved in a replacement manner is avoided.

    本发明属于汽车技术领域,具体涉及一种非替换式节约内存的行车记录用系统,包括行车记录仪,以及与该行车记录仪相连的云服务器;其中所述行车记录仪用于采集行车影像,并将实时的行车位置数据发送至云服务器;所述云服务器接收行车位置数据,并且计算行车位置的道路危险度指数,将道路危险度指数发送至行车记录仪;所述行车记录仪根据道路危险度指数调节存储视频分辨率。本发明通过行车记录仪确定当前位置,通过云服务器计算当前位置的危险度指数,并根据危险度指数调节存储视频分辨率,优化了存储空间,避免了采取替换式节约存储空间时会出现的漏秒问题。
