    Abstract: The present disclosure relates to a Controller Area Network, CAN, controller, comprising: an input interface, a transmit data, TXD, interface, and a processing unit, wherein the input interface is coupled to the processing unit, wherein the processing unit is configured to receive via the input interface a data packet comprising a packet priority field, a packet payload field, wherein the processing unit is configured to generate a first CAN frame based on the data packet, such that a first payload field of the first CAN frame represents at least the packet payload field and a first identifier field of the first CAN frame comprises a first identifier part and a second identifier part, wherein the first identifier part represents predefined data for identifying the CAN controller, and wherein the second identifier part represents the packet priority field and/or comprises a queue field representing a queue priority for the first CAN frame, wherein the processing unit is coupled to the TXD interface, and wherein the processing unit is configured to send the first CAN frame via the TXD interface. The present invention also relates to a CAN device and a method for the CAN controller.

    Abstract: The disclosure relates to a controller area network, CAN, transceiver and a CAN controller. The CAN transceiver is configured to: compare a signal from the CAN bus with a negative threshold level; and provide a wake-up indication to the CAN controller based on the signal matching a predetermined pattern of one or more periods in which the signal is less than the negative threshold level. The CAN controller is configured to provide instructions to transmit a wake-up indication on the CAN bus.

    IPC: H04L12/40

    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: Embodiments of a device and method are disclosed. A controller area network (CAN) device includes a compare module configured to interface with a CAN transceiver, the compare module having a receive data (RXD) interface configured to receive data from the CAN transceiver, a CAN decoder configured to decode an identifier of a CAN message received from the RXD interface, and an identifier memory configured to store an entry that corresponds to at least one identifier, and compare logic configured to compare a received identifier from a CAN message to the entry that is stored in the identifier memory and to output a match signal when the comparison indicates that the received identifier of the CAN message matches the entry that is stored at the CAN device. The CAN device also includes a signal generator configured to output, in response to the match signal, a signal to invalidate the CAN message.

    Abstract: A Controller Area Network, CAN, transceiver comprising a receiver arrangement for coupling to a CAN bus and configured to determine a differential signal from analog signalling received from the CAN bus; and a receive output for coupling to a CAN controller and wherein the receiver arrangement provides a digital output signal to the receive output based on the differential signal; wherein the receiver arrangement operates in at least a first mode in which it is configured to provide the digital output signal comprising logic 0 when the differential signal is greater than a first receiver threshold and provide the digital output signal comprising logic 1 when the differential signal is less than said first receiver threshold unless said differential signal satisfies a condition, whereupon the receiver arrangement is configured to provide the digital output signal comprising logic 0, wherein the condition comprises the differential signal being below an activity-voltage threshold.
