  • Abstract

    A FlexRay network guardian including: a resetting leading coldstart node (RLCN) detector configured to detect a RLCN failure; a deaf coldstart node (DCN) detector configured to detect a DCN failure; a babbling idiot (BI) detector configured to detect a BI failure; and a FlexRay network decoder configured to output a signal regarding the status of the FlexRay network to the RLCN detector, DCN detector, and BI detector, wherein the RLCN detector, DCN detector, and BI detector are configured to send an indication of a failure to a containment module.
