System Architecture of the Automotive Door Lock Module

In this system, the vehicle body control network employs a hybrid CAN/LIN architecture. Based on functional classification, it is divided into various modules: in addition to the door lock module, the body system comprises the seat module, control panel module, and lighting module. These modules are interconnected via a CAN bus, while internal interconnections within each individual module are established using a LIN bus.

The door lock module constitutes a critical component of the vehicle's body electronics. Through a wireless remote door locking system managed by a master node, the intelligent electronic control units (ECUs) for each door can be controlled with great convenience; simultaneously, the system provides real-time feedback regarding the operational status of the nodes, thereby significantly facilitating both operation and maintenance.
