FlexRay is a serial communication technology used for data communication in transportation media. The FlexRay interface is made up of a communication controller and one or two bus drivers, depending on the number of channels. Each FlexRay communication cycle ends with a very special segment, the Network Idle Time (NIT). cation protocols. Step 4:A minislot is lost even when a task does not transmit any message.
