Abstract: A method of common controller area network (CAN) bus traffic supervision on a system having a common CAN bus, a first CAN chip and a second CAN chip, the first CAN chip and the second CAN chip are coupled together with the common CAN bus, the method includes comparing a first CAN frame received from the first CAN chip to a second CAN frame received from the second CAN chip within a CAN comparison period, and detecting a failure of at least the first CAN chip or the second CAN chip. Detecting the failure of at least the first CAN chip or the second CAN chip includes determining that the first CAN frame is not identical to the second CAN frame within the CAN comparison period.
