Abstract: The disclosure relates to a transceiver device, an electronic control unit and an associated method. The transceiver device is suitable for communicating between one or more network protocol controllers and a network bus and comprises: first interface circuitry configured to communicate with the one or more network protocol controllers; second interface circuitry configured to communicate with the one or more network protocol controllers; and selector circuitry configured to switch communication with the one or more network protocol controllers from the first interface circuitry to the second interface circuitry in response to a communication error in data carried on the first interface circuitry.

Abstract: A network node for coupling to a communication bus, the node comprising:
a receiver configured to receive messages from the communication bus; and a transmitter configured to transmit first messages having a first message format and configured to transmit diagnosis messages having a second message format on the communication bus for use in determination of communication errors, wherein said transmitter is configured to send said one or more diagnosis messages having one or more of:
(i) a predetermined pattern of symbols;
(ii) a predetermined sending schedule;
(iii) a predetermined line encoding method;
(iv) a predetermined bit rate;
(v) a predetermined position in one or more of the first messages;
(vi) a predetermined signalling frequency that is out of a frequency band used for transmission of the first messages; and
(vii) a predetermined signal strength different from the signal strength used to send the first messages.-

Abstract: The disclosure relates to a transceiver device for communicating between a network protocol controller and a network bus, the transceiver device comprising: transceiver circuitry configured to transmit and receive data on the network bus using a first physical layer protocol; and monitoring circuitry configured to determine a measured property of the network bus, in which the transceiver device is configured to: determine whether the measured property indicates an error condition; and reconfigure the transceiver circuitry to transmit and receive data on the network bus using a second physical layer protocol in response to determining the error condition.

Abstract: Embodiments of a device and method are disclosed. In an embodiment, a method for communicating data frames on a bus that operates according to a multi-master bus protocol is disclosed. The method involves beginning transmission of a data frame from a node on the bus when the node gains control of the bus, wherein the multi-master bus protocol specifies a frame format that includes a start portion, a payload portion, and an end portion, during transmission of the payload portion of the data frame, inserting an in-payload arbitration field into the transmission, continuing transmission of the data frame if the node maintains control of the bus after insertion of the in-payload arbitration field, and halting transmission of the data frame before transmission of the data frame is complete if the node losses control of the bus after insertion of the in-payload arbitration field.
