Abstract:
Disclosed is a method for transmitting CAN messages via a CAN bus in a communication system including several network nodes with at least one respective CAN controller. According to the method, the authorization of a network mode to send a CAN message is arbitrated, an arbitration decision being made in a higher protocol layer than the transmission of the CAN message, and the CAN message is already sent by the transmitting network node, the latter providing a dominant level in the ACK field of the message. A network node which receives the CAN message does not generate a dominant level in the ACK field and does not send a complete error frame.
