Abstract

OSEK NM (Network Management) is one of the important mechanisms to guarantee the safety of the automotive network and its working reliability has direct effect on the network communication. In order to analyze and improve the reliability, the logical ring reconstruction mechanism is improved in the scenarios of node joining and dropping out. Meanwhile the time of ring reconstruction is reduced. Through the potential failure factors analysis and the quantitative calculation model in OSEK NM fault tree, an updated ring mechanism is proposed to improve the performance of OSEK NM. Simulation results prove the validity of the method in this paper which can effectively increase the reliability of OSEK NM.
