  • Fault localization and health indication for a controller area network
    Patent number: 6959403
    Abstract: A node of a network comprises an error message detector arranged to detect error messages transmitted over the network, a counter arranged to count the error messages in order to produce an error message count, and a controller arranged to count valid messages in order to produce a count of valid messages. The controller is arranged to compare the error message count to the valid message count to indicate the health of the network. The node further comprises a transceiver, a controller coupled to the transceiver by a receive line and a transmit line, and error message first logic coupled to the receive and transmit lines. The error message first logic is arranged to detect a first error message from the receive line and a second error message from the transmit line, and to determine whether the node is closest to a fault by comparing timing between the first error message and the second error message.
