Automotive CAN Bus System Principles, Design and Applications

About this manual

This book introduces the basic principles of the Controller Area Network (CAN) used in automotive electronic control units, describing its architecture, functions and physical characteristics. It explains the three main layers—physical, data link and application—along with related protocols such as SAE J1939 and TTCAN.

The text also discusses design considerations, implementation methods, and practical examples for developing CAN‑based systems, including topics like message framing, error handling, CRC, and bootloader integration. This manual is written in Chinese.
