How Long Will CAN Stick Around As Rival Networks Speed Up?

Key Highlights:

Here’s the summary in HTML format with concise bullet points:

Automotive Ethernet Dominance: Automotive Ethernet is emerging as the backbone for software-defined vehicles due to higher bandwidth, determinism (TSN), and security, outperforming legacy protocols like CAN and LIN.
Legacy Protocol Persistence: CAN, LIN, and FlexRay remain entrenched due to cost-effectiveness and reliability but are increasingly inadequate for AI-driven, centralized architectures.
Transition Challenges: Integration complexity, cost sensitivity, and legacy components slow adoption, requiring digital twins and hybrid architectures during the coexistence phase.
Future Outlook: Ethernet is expected to replace CAN/LIN in 5–10 years, especially with 10BASE-T1S at the edge, while SerDes and optical Ethernet will handle high-speed backbones.
AI and Zonal Architectures: AI-driven demands and zonal designs accelerate Ethernet adoption, but full transition hinges on cost reductions, standardization, and OEM validation.
