Provided is a high-speed (CAN) transmission method capable of improving the data rate of a CAN interface used for distributed real-time communication and control means of a vehicle or an automation control apparatus. By maintaining the compatibility with an existing CAN standard, the largest advantage of the invention is that high-speed data transmission is possible on the same CAN bus where existing CAN devices operate. Using the high-speed transmission method, an existing standard CAN signal and a passband signal including high-speed data are transmitted simultaneously. A high-speed CAN device of the present invention simultaneously transmits the standard CAN signal and the high-speed data in a passband while operating on the same bus as the existing CAN devices. The passband signal is transmitted only in dominant bit transmission interval of the existing CAN signal, and transmission of the passband signal is configured to have certain limitation to ensure the compatibility with existing CAN node devices. |
