Design and Implementation of Fault Diagnosis for Automotive BCM
In order to better save the cost of automotive electrical systems,this article has completed the de-sign of a relative current feedback device for the BCM load control system,which includes relevant diagnostic methods for circuit overload,short circuit faults,and open circuit faults.Capable of timely and effective monito-ring of partial working currents,as well as selecting corresponding models based on specific changes in load cur-rents and driving schemes,providing accurate judgments on overload and short circuit faults,ensuring that load startup and shutdown are maintained in a normal state.This not only achieves the original load control system,but also completes the closing protection in the process of short circuit faults and overload faults.
