摘　　要：经过充分调查研究车载以太网的理论基础和国内外发展情况,以当前车辆行业市场需求为背景,对比当前车载网络技术优势和不足,设计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,利用其可在Reserves MII模式下工作的优势,进行BACK-TO-BACK电路板硬件设计,重点围绕TJA1100进行硬件环境搭建。Based on fully investigation and study of the theoretical basis of automobile Etbernet and the development situation at home and abroad, taking the current market demand of vehicle industry as the background, compared with the current vehicle network technology advantages and shortcomings, a method is put forward that verifies vehicle Ethemet connectivity and real transmission rate of the circuit board. This solution is based on NXP＇ s TJA1100 transceiver chip, which can be used in the Reserves MII mode, to conduct BACK-TO-BACK circuit board hardware design, focusing on TJA1100 hardware environment building.
