Classification: CPC H | IPC H

Claim 16:
17. A vehicle heterogeneous communication method for CAN message reception of a transceiving controller, comprising:
checking, by a physical layer (PHY) module, presence of a start of stream delimiter 4 (SSD4) symbol by checking a number of SSDs based on an Ethernet frame being received from a transmitting side;
determining a corresponding Ethernet frame as a CAN message delivery Ethernet frame based on the number of SSDs being 4 and the SSD4 symbol being present;
delivering the CAN message delivery Ethernet frame to an MCU through a controller area network (CAN) dedicated line added to a media independent interface (MII);
performing, by the MCU, processing of the CAN message delivery Ethernet frame through media access control (MAC); and
storing the CAN message delivery Ethernet frame in an internal CAN message storage memory.
