BBW(Brake-by-wire) 시스템의 Parity space 접근법을 이용한 모델기반 센서 고장진단 알고리즘 개발

Abstract

The brake-by-wire(BBW) system, which is also called the EMB(Electro-Mechanical Brake) system, has become a promising vehicle braking control scheme. Fault detection and diagnosis becomes increasingly important for the robust BBW system. In this paper, the clamping force sensor fau lt detection algorithm is proposed with parity equation method for EMB system. At first, modeling of EMB system including PMSM(Permanent-Magnet Synchronous Motor) was carried out. Also, in order to verify the EMB model, the simulation result is compared to EMB test bench result. The mo del based fault detection algorithm is verified through the closed loop simulation.
