Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A vehicle heterogeneous communication system for controller area network (CAN) message transmission between heterogeneous communication controllers in a vehicle, the system comprising:
a first transceiving controller configured to transmit a CAN message delivery Ethernet frame to which a start of stream delimiter 4 (SSD4) symbol is added by changing a start of stream delimiter (SSD) size with respect to a first Ethernet frame; and
a second transceiving controller configured to:
recognize, based on the SSD4 symbol being detected by checking an SSD of Ethernet frame received from the first transceiving controller, the received Ethernet frame as the CAN message delivery Ethernet frame, and
performing CAN message delivery Ethernet frame processing in which a media access control (MAC), Internet protocol (IP), and user datagram protocol (UDP) analysis step in processing the first Ethernet frame is omitted.
