자율 주행 차량 EHB 시스템 고장 진단 알고리즘 설계를 위한 Redundancy 분석

초록

In this paper, we propose a redundancy analysis for designing fault diagnosis of EHB system. The structural analysis is intended to express the relationship between variables and constraints. Prior to structural analysis, the EHB system dynamics are analyzed, and fault analysis model is developed. And to verify the consistency of fault analysis model, a fault simulation environment is established and compare the results. The direction of signal or fault propagation can be analyzed through matching and causal interpretation. Then we can find sensor and actuator signals for fault diagnosis and redundancy
