The fault injection unit composed of self-developed fault injection boards can be interconnected in series between ECU and HIL system. The unit controlled via one serial communication port RS232 or CAN is able to make the channel an open circuit, shorted to the ground, to the UBat or to any user-defined channel. The host computer program written by NI LabVIEW supports importing the configuration file for fault injection mode of each channel by one click, proved to be flexible and reliable.%使用自行开发的故障注入板卡组成故障注入箱,串联在ECU与硬件在环(HIL)系统之间,通过CAN总线或串口控制,实现任一通道的开路、对地或对电源短路及任意两通道之间短路故障注入.基于NI公司的LabVIEW软件编写上位控制界面,支持一键导入各通道故障注入模式配置文件,使用灵活可靠.
