전압 및 전류 모니터링을 이용한 차량 내 IPS(intelligent power switch) 진단 시스템에 관한 연구

This paper presents the design of hardware and software of CAN communication based IPS (Intelligent Power Switch) evaluation system and its application to evaluation of real IPS module in developing car. The evaluation system performs the evaluation automatically which are switching the load on or off, reading IPS load voltage and current, changing the connection of IPS to different states automatically, analyzing the IPS current, voltage and CAN messages which contain diagnostic feedback from IPS module.
