Gelonghui November 8th | Yu Taiwei (688515.SH) investor relations activity records show that as early as 2019, GAC had completed the research and development of in-vehicle Ethernet platform. The Ai'an model has been mass-produced with in-vehicle gigabit Ethernet since then, and since the Starlink architecture, in-vehicle 10-gigabit Ethernet technology has been fully applied. From the current situation, the rapid iteration of the electrical/electronic architecture is driven by the convergence of the entire vehicle communication network. It has become the consensus of major manufacturers to use Ethernet as the backbone for in-vehicle communication starting from the domain control architecture. The subsequent series of in-vehicle Ethernet products, including in-vehicle Ethernet physical layer chips, in-vehicle Ethernet switch chips, will significantly increase market usage. Meanwhile, with the gradual development of functions such as navigation assistance, automatic lane change, automatic parking, intelligent summoning, and traffic signal recognition, some domestic new energy brands have already been equipped and put into use. This will greatly promote the rapid penetration of in-vehicle Ethernet into the automotive industry. The company's in-vehicle gigabit Ethernet physical layer chips and in-vehicle 10-gigabit Ethernet physical layer chips are already in mass production. The in-vehicle Ethernet switch project has begun interoperability testing with customers, and further cooperation will be carried out in the future, becoming one of the supporting product lines for the company's in-vehicle high-speed wired communication chips. The company has now entered the GAC Ai'an supply chain system and become one of the suppliers of its in-vehicle Ethernet physical layer chips. The company's in-vehicle Ethernet physical layer chips have been applied to some models of GAC Ai'an. With the increase in shipping volume of GAC Ai'an and the deepening of smart features, the company's shipment of in-vehicle chips is expected to increase, which will also contribute to the development and technological innovation of both parties in the smart automobile field.
