汽车事件数据记录（EDR）系统数据读取方案研究

Research on Data Retrieval Scheme of Event Data Recorder (EDR) System

汽车事件数据记录系统能够自动地记录车辆事件发生前后一段时间内的车辆运行和车辆安全系统状态信息,例如:车辆速度、车辆碰撞后的加速度、方向盘的转向角度、发动机运作状态、气囊状态、驾驶辅助系统、驾驶人在事件发生时的反应动作等重要信息。当车辆发生事件后时,通过采集、分析事件数据记录系统所记录的车辆状态、驾驶人反应动作等数据,可以推断出车辆在发生事件前后的实际运行参数,为事件分析鉴定提供了客观、公正的技术支持。而汽车事件数据记录系统数据读取方案的研究,为第三方独立读取数据,提供了有效的技术保障。

The event data recorder system can automatically record vehicle operation and vehicle safety system status information for a period of time before and after a crash event, such as: vehicle speed, acceleration after a collision, steering angle of the steering wheel, engine operating status, airbag status, driving Important information such as assistance systems and driver’s reaction to the event. When a event occurs, by collecting and analyzing data such as vehicle status and driver reaction actions recorded by the event data recording system, the actual operating parameters of the vehicle before and after the event can be inferred, providing an objective and fair event analysis and identification Technical support. The research on the data retrieval scheme of the event data recorder system provides an effective technical guarantee for the third party to independently retrieve the data.
