| Abstract: | The reliability of brake-by-wire(BBW) system is analyzed by using the method combing failure modes & effects analysis(FMEA) and fault tree analysis(FTA).A design method for system redundant structure is proposed based on the combination of reliability analysis and fault tolerant technology,and a double redundant structure is designed for BBW system.The results of study show that the structure can meet the reliability requirements of system.Finally key technologies for enhancing system reliability are expoun... |
