Abstract

To verify the function of vehicle is becoming more and more difficult because many electronic control units have been embedded in vehicle with development of electronics industry. The reliability of vehicle should be considered above all important because malfunction of vehicle can cause damage of human life. In this paper, defect diagnosis platform based on CAN network is proposed to improve the reliability of vehicle. Reliability of vehicle is significantly increased by adopting the structural test via dedicated test path after manufacturing. Besides, the test cost is reduced because additional test pins are not required.

전자 산업의 발달과 함께 많은 전자 제어 장치가 차량 내부에 탑재됨에 따라 차량의 기능을 검증하는 것은 더더욱 어려워지고 있다. 차량의 기능 오작동은 인명손실의 우려가 있기 때문에 차량에 있어서 신뢰성은 무엇보다 중요하게 고려되어야 한다. 본 논문에서는 차량의 신뢰성 향상을 위한 CAN 통신 기반의 고장 진단 플랫폼을 제안한다. 양산 이후에도 독립적인 테스트 경로를 통한 구조적 테스트를 실시함으로써 차량의 신뢰성은 크게 증가할 것이다. 또한, 별도의 테스트 핀이 필요하지 않기 때문에 테스트 비용을 절감할 수 있다.
