摘要

随着以太网在汽车领域的推广和普及,车载以太网网关将很快推出市场。相比上一代网关,以太网网关新增了许多新的设计点,对电气性能也提出了更高的要求,只有在开发设计和验证过程中,对关键参数进行严格控制,才能保证整个车载以太网网络系统的稳定运行;从而,使以太网网关在提升通信性能的同时,为整车带来新的功能体验。
        With the popularization of Ethernet in the automotive field, vehicular Ethernet Gateway will soon be launched in the market. Compared with the previous generation gateway, the Ethernet gateway adds many new design points, and puts forward higher requirements for electrical performance. Only in the process of development, design and verification, the key parameters are strictly controlled, can the stable operation of the whole vehicle-mounted Ethernet network system be ensured, while improving communication performance, new functional experience be brought to the vehicle.
