Research on Fault Tolerant Strategy and Reliability of Steering-by-Wire

Zhongyi Hu, Fengdeng Zhang , and Zhiqiang Wei
Abstract—In this paper, we introduce a methodology for the reliability analysis of the redundant steering-by-wire system. With rapid development of modern automotive electronics and deep electronic degree, it is necessary to analyze the reliability of system to fully understand and quantify the failure mechanisms in order to improve the design. Several system level FMEAs are used to identify the different failure times of system and a markov model is constructed to quantify their probability of occurrence. For the safety-critical real-time system, the redundancy, failure rate and fault coverage of component are important factors to the reliability of system. It is, therefore, necessary to develop a highly dependable SBW system architecture to ensure the security of car by using redundancy, decreasing failure rate, or increasing fault coverage.

Index Terms—Steering-by-wire (SBW), failure mode and effects analysis (FMEA), markov model, redundancy.
