汽车连接能力测试

As transportation becomes more connected, and new features become more critical, systems designers, OEMs and suppliers need to verify their operation at all stages of development. Spirent offers a wide range of solutions to help verify that automotive networking and communication systems perform as intended and to evaluate performance of the latest technologies.

10BASE-T1S technology was developed as part of the IEEE 802.3cg-2019 standard to enhance in-vehicle Ethernet networks by providing Ethernet-to-the-edge connectivity, which is essential for zonal-based automotive architectures. It offers a cost-effective solution by utilizing a multidrop bus topology, allowing multiple devices to connect via a single unshielded twisted pair cable without the need for switches or gateways. This brief provides an overview of 10BASE-T1S technology, including related benefits, testing challenges and key testing considerations, along with setup and configuration guidelines to ensure optimal performance and reliability in both peer-to-peer and multidrop environments.

了解10BASE-T1S以太网如何提供新的优势，使其非常适合广泛的汽车应用，其中包括跨多个领域的传感器与执行器。
