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

Claim 11:
12. A vehicle heterogeneous communication method for controller area network (CAN) message transmission of a transceiving controller, the method comprising:
generating, by a micro controller unit (MCU), a CAN message delivery Ethernet frame in which a start of stream delimiter (SSD) size is changed through media access control (MAC);
delivering the CAN message delivery Ethernet frame to a physical layer (PHY) module through a CAN dedicated line added to a media independent interface (MII);
checking, by the PHY module, an Ethernet frame received through the CAN dedicated line;
recognizing the Ethernet frame as the CAN message delivery Ethernet frame;
inserting, by the PHY module, four SSDs acquired by adding an SSD4 symbol into the CAN message delivery Ethernet frame; and
transmitting the CAN message delivery Ethernet frame to a receiving side.
