Claim 1: Method for the serial communication by exchange of data frames between a transmitting node and at least one receiving node who are connected by means of a bus system,
wherein the roles of transmitter and receiver are assigned to nodes for each data frame by the arbitration procedure defined in the CAN-Standard ISO 11898-1, wherein the exchanged data frames have a logical structure according to the CAN-Standard ISO 11898-1,
wherein the data frames are composed of a sequence of bits,
wherein the logical structure of the data frames includes a Start-Of-Frame-Bit, an Arbitration Field, a Control Field, a Data Field, a CRC Field, an Acknowledge Field and an End-Of-Frame Field,
wherein each bit has a bit time,
wherein each bit time is divided into Time Segments (SYNC_SEG, PROP_SEG, PHASE_SEG1, PHASE_SEG2), characterized in that in response to a predefined value of a specific bit within the Control Field a first node belonging to a first group of nodes restarts its protocol decoding state machine and waits until it has synchronized itself to the bus activity
and a second node belonging to a second group of nodes communicates using the communication protocol according to CAN FD Specification. |
