INDICATING INTERNAL TRANSMITTER ERRORS IN A CONTROLLER AREA NETWORK (CAN)

摘要

Systems and methods for indicating internal transmitter errors in a Controller Area Network (CAN). In some embodiments, a method may include initiating, by a device coupled to a CAN, transmission of a message via the CAN; detecting an error by the device during the transmission; and continuing, by the device after having detected the error, the transmission of the message without causing or indicating a bus error condition. In other embodiments, a CAN node may include message processing circuitry configured to receive a frame from a transmitter, the frame comprising a cyclic redundancy check (CRC) field, the message processing circuitry further configured to identify an internal error of the transmitter based upon the CRC field.
