自动驾驶汽车事件数据记录装置的研究与设计

Research and Design of Automatic Driving Vehicle Event Data Recording Device

当前,道路交通状况日益复杂且汽车自动驾驶能力逐年提升,而国内汽车事件数据记录装置往往无法同时支持视频监测、车辆状态、轨迹定位等多源数据的采集存储。因此,本文根据自动驾驶电动汽车公共道路测试和通行安全的根本要求,研究了数据标准化采集融合、事件识别分析和数据提取存储技术,实现提供全过程监管的自动驾驶汽车事件数据记录装置。该装置能够全面客观监测行驶环境、车辆状态、轨迹定位等信息,并通过系统时钟源做统一记录,存储在FLASH中并上传云端。

According to the basic requirements of public road test and traffic safety of autonomous electric vehicle,the event data recording device of autonomous electric vehicle is developed.The research mainly focuses on data standardization acquisition interaction and fusion technology,event identification and analysis early warning technology and event data recording device,so as to realize highly reliable identification,analysis and early warning of driving events of autonomous electric vehicles.Finally,the test of the event data recording device of autonomous electric vehicle in real vehicle-deviceplatform is completed,and it is applied to the whole process supervision of the ability test of autonomous electric vehicle.
