The invention discloses a method and a system for managing vehicle-mounted event data. The method comprises the following steps: acquiring a real-time picture; identifying real-time picture information; caching and recording real-time picture information of the fixed data frame in real time; the real-time picture information is combined with driver operation data and vehicle state data, and power, braking and steering control requests are sent out according to the combined data and control logic; after the control request is executed, vehicle driving control and state information are formed and fed back; receiving vehicle driving control and state information, acquiring real-time picture information of a certain data period when judging that a triggering condition is met, obtaining a group of picture information, and forming a group of event triggering EDR data in combination with the group of picture information and the vehicle driving control and state information; and performing storage management and control on the event-triggered EDR data according to a preset data storage space allocation control logic. According to the invention, the storage space and transmission time of the local picture information after the vehicle event is triggered are effectively saved, and the working efficiency of problem analysis is improved.
本发明公开了用于管理车载事件数据的方法及系统,方法包括:获取实时图片;识别实时图片信息;实时缓存并记录固定数据帧的实时图片信息;将实时图片信息与驾驶员操作数据、车辆状态数据结合,依据结合数据与控制逻辑发出动力、制动和转向控制请求;在执行控制请求后形成车辆驾驶控制及状态信息并反馈;接收车辆驾驶控制及状态信息,当判断符合触发条件时,获取一定数据周期的实时图片信息,得到一组图片信息,结合一组图片信息和车辆驾驶控制及状态信息,形成一组事件触发EDR数据;按照预设的数据存储空间分配控制逻辑对事件触发EDR数据进行存储管控。本发明有效节省了车辆事件触发后本地图片信息的存储空间及传输时间,提高问题分析的工作效率。
