| 摘 要： | 毫米波雷达用于盲区监测系统时,一种连接方法是仅一个雷达挂接在车身网络上,而另一个雷达无法直接与车身网络通信,因此也无法通过OBD直接升级软件。该文提出一套基于UDS的软件升级方案,在传统下位机Bootloader中增加主从通讯功能,使得两个雷达能同时完成软件升级。经实际应用,设计的Bootloader在盲区监测系统和前碰撞预警系统中都能可靠地升级应用软件。

| Abstract: | When millimeter wave radars are used in a blind spot detection(BSD)system,where only one radar working as the main radar is connected to the vehicle network directly,the sub radar that cannot communicate with vehicle network cannot be pro?gramed by OBD interface.In order to achieve the program upgrade of two radars,a program upgrade method based on unified diag?nostic services(UDS)is proposed.The method adds a master-slave communication function in traditional Bootloader.The Boot?loader designed is proved that it can upgrade software correctly and reliably in BSD system and forward collision warning(FCW)system. |
