The hardware architecture of BCM includes a core microprocessor for receiving and processing signals from sensors and switches; input interface for receiving signals, output interface for controlling electrical equipment; memory for storing programs and data; communication interface for communicating with other electronic control modules. BCM controls the body electrical equipment according to preset programs by receiving signals from sensors and switches.
Development history and future trends
With the continuous development of automotive electronic technology, BCM has become more and more powerful, and centralized structure has become a development trend. The centralized structure uses fewer modules to achieve more functions, simplifies network connections, improves cost-effectiveness, and reduces the weight of the wiring harness. However, this structure also faces the problem of exhaustion of microcontroller input/output ports, which needs to be solved by adding discrete components.
