This chapter mentions numerous points which are often passed over in silence in general presentations of the FlexRay protocol. It describes the wakeup process of the network and the principal state diagrams related to it. But to begin with, the chapter first considers that all the ECUs are placed in sleep mode to economise on energy, and that if an external event occurs, it will be capable of waking up the cluster. The particular mode of access to the network of TDMA type used for FlexRay necessitates that all the nodes are strictly synchronised in the cluster. The aim of the startup procedure is to initialise, to implement the synchronism and to establish a common global clock, in order to produce common sequencing for all the nodes. The FlexRay error management philosophy is principally demonstrated in a ‘never give up’ strategy and robustness against transient faults.
