摘　　要：车载以太网逐渐成为汽车制造商设计与研发的重要方面。如何将以太网真正应用到车载领域,实现车载环境下数据的高速传输,成为目前研究的重点。本文设计了一种用于验证车载以太网实际连通性能和真实传输速率的电路板。该方案基于恩智浦公司的TJA1100收发器芯片可在Reserves MII模式下工作的优势,设计了BACK-TO-BACK电路板硬件,重点围绕TJA1100搭建硬件环境,为后续汽车生产商车载以太网节点的开发或车载AVB环境的搭建提供参考依据。Vehicle Ethernet has gradually become an important field for the design and development of automotive manufacturers. How to apply Ethernet in the vehicle field and realize the high-speed data transmission in the vehicle environment has become the focus of the current research. In this paper, a circuit board is designed to verify the actual connectivity and the true transmission rate of the on-board ethemet. The scheme of TJA1100 transceiver chip based on NXP, which can work in Reserves Mil mode the advantages, design the hardware circuit board of BACK-TO-BACK, the key hardware environment is built around the TJA1100, provides a reference for the follow-up to build car manufacturers car or car AVB Ethemet node development environment.
