The Body Control Module (BCM) is a cornerstone of automotive electronic control systems. It oversees a variety of vehicle electrical systems, such as lighting, windows, doors, seat adjustments, mirror controls, anti-theft alarms, remote control, and tire pressure monitoring. The BCM ensures the efficient operation of these systems, offering real-time feedback to enhance driving safety and comfort.

A typical body control system incorporates essential hardware, including an MCU, signal acquisition modules, communication modules, power modules, drivers, and sensors. As the progress of automotive electrification and intelligence continues, vehicle electronic architectures become increasingly complex and interactive. This trend drives BCMs to shift from distributed to centralized systems, integrating more features and functionalities.
