To support the massive data transmission of central computing architectures, in-vehicle network bandwidth has experienced exponential growth. In the backbone connecting various area controllers and HPCs, Automotive Ethernet combined with Time-Sensitive Networking (TSN) has become an irreplaceable standard. Its transmission rates have jumped from the early 100BASE-T1 to gigabit (1Gbps) and even multi-gigabit (2.5G/5G/10G) levels, ensuring the absolute low latency and time determinism required for high-resolution radar/LiDAR sensor data, lossless image streams, and OTA (Over-The-Air) big data transmission .
However, in the edge regions, end effectors, and cost-sensitive drive and body control domains, it is not economically viable to equip each node with an expensive Ethernet PHY chip. To address this, the next-generation CAN XL technology was developed. CAN XL increases the data segment transmission rate of traditional CAN networks to 10-20 Mbps and supports data lengths of up to 2048 bytes.This groundbreaking specification allows CAN XL to directly encapsulate and transmit standard Ethernet IP packets, becoming a perfect bridge between traditional CAN/CAN FD end-point networks and high-speed Ethernet backbones.This allows automakers to achieve IP-based and service-oriented communication at the vehicle's core without fully bearing the high hardware costs of Ethernet.Meanwhile , IEEE 10BASE-T1S (10 Mbps multi-node single-pair Ethernet) is also gaining popularity as a strong competitor in China and among some new car manufacturers that value pure software- defined architectures.
