Abstract : The CAN protocol possesses fault confinement mechanisms aimed at differentiating between short disturbances caused by electromagnetic interferences (EMI) and permanent failures due to hardware dysfunctioning. In this study, we derive a Markovian analysis of these mechanisms and identify several problems. We then propose new mechanisms in order to address them.
