Evaluation of CAN-Based and DoIP-Enabled TCUs
27 Oct 2026
Day 1 PM - The Foundations
Evaluating CAN-based and DoIP-enabled telematics control units (TCUs) is essential to advancing software-defined vehicle architectures. CAN supports established control functions, while Diagnostic over Internet Protocol (DoIP), carried over automotive Ethernet, enables higher-capacity diagnostics and software transfers. Their comparison encompasses bandwidth, scalability, interoperability and cybersecurity, with hybrid architectures balancing existing network requirements and growing connectivity demands. By harmonizing diverse software layers, manufacturers can maintain seamless connectivity without compromising robust token-based cybersecurity. Coordinated security controls and standardized interfaces underpin resilient TCU integration, supporting efficient software updates and dependable communication across increasingly interconnected vehicle systems.
