基于CAN总线的汽车事件数据记录系统开发方案研究

Research on The Development Schemes of Event Data Recorder System Based on CAN Bus

汽车事件数据记录系统为重组交通事故现场提供了全面客观的数据,在国际上受到越来越多的关注,国内也开始编制相关系统的法规。本文结合国内法规要求,提供4种基于CAN总线的汽车事件数据记录系统开发方案,适用于不同的电子电气架构设计。

Event data recorder system provides comprehensive and objective data for reorganizing the traffic accident scene.The system has received more and more attention in the world.China also began to compile theregulation of the relevant system.Combined with the regulation,the paper provides four development schemes of event data recorder system based on CAN bus,which are suitable for the different design of electrical and electronic architecture(EEA).
