EMB의 센서 고장 감지 시스템 개발

The brake-by-wire units such as EMB(Electro-Mechanical Brake) will be adopted to the next-generation intelligent vehicles because the brake-by-wire units are lighter in weights and have faster response compared to conventional hydraulic brake units. Advanced chassis controllers such as ABS, TCS, ESP and EBD show better performance with the brake-by-wire units. However. the brake-by-wire units such as EMB should be at least as reliable as the conventional hydraulic brake units. In this study, a model-based fault diagnosis system is developed for monitoring the brake status based on the analytical redundancy method. The performance of the proposed model-based fault diagnosis system is verified in simulations in various faulty cases.
