Application of LIN bus in modern automobiles

LIN bus, as a low-cost and simple serial communication protocol, is becoming a key technology in modern automotive electronic systems. This bus is designed to connect various on-board electronic devices, such as doors, windows, lights and central locks, so as to realize data exchange and transmission of control instructions between these devices. The core advantage of LIN bus lies in its single master/multiple slave mode. This architecture not only reduces the complexity and cost of the system, but also improves the reliability and flexibility of the system. In addition, LIN bus also has predictable electromagnetic compatibility performance, and the maximum transmission rate is limited to less than 20kbps, which effectively limits electromagnetic interference. With the continuous development of the automotive industry, LIN bus will play an increasingly important role in future automotive electronic systems.
