  Abstract

As the number of ECUs and data rate increase with autonomous driving and electric vehicles, many changes are being made to vehicular communications. The CAN (Controller Area Network) 2.0 method, which was mainly used in the past, has a limitation in that it can send only a small amount of data at a low speed of up to 1 Mbps. On the other hand, automotive Ethernet can transmit a large amount of data at a higher speed than CAN communications, but it is difficult to use it alone due to its network topology different from the conventional networks, the need for many switches, and the complexity of wiring. Therefore, currently, CAN communication and automotive Ethernet are separated within the vehicle and are used by configuring different networks. In this paper, we propose a network that integrates CAN communication and Ethernet using 10Base-T1S Ethernet. In the integrated network, CAN signals are converted into Ethernet packets and connected to other nodes via the 10Base-T1S Ethernet bus. Meanwhile, the CAN packet time delay problem that may occur due to the Ethernet protocol was solved by assigning priority to the packet, and the performance is evaluated.
