Design of CAN — CAN FD bridge for in-vehicle network

In this paper, we propose the communication bridge circuit between controller area network (CAN) and controller area network with flexible data-rate (CAN FD) protocol for in-vehicle network. The bridge transmits the CAN and CAN FD, supporting the electronic control units (ECUs) in different communication protocol. The prototype of the CAN FD bridge controller is implemented on an Field Programmable Gate Array (FPGA). Experimental result using a hardware scope demonstrates the feasibility of our proposal.
