Abstract
The present invention relates to a verification system and method for BCM software wherein data extracted from an orthogonal array are applied to verification for BCM software to reduce the number of tests such that verification for each BCM can be performed in a short period of time before manufacturing a prototype, reliability of verification results can be improved using a verification program regardless of an evaluator, and errors in the software for each BCM can be found and corrected at an early stage.
To this end, the present invention provided a verification system for BCM software which comprises a BCM for controlling functions of convenience equipment in a vehicle; a computer equipped with a verification program and capable of exchanging information with the BCM through serial communication; and a power supply unit for applying power to the computer and the BCM.

7. A verification method for BCM software, comprising the steps of:
-
creating a plurality of input signals into an Excel file using an orthogonal array; inputting orthogonal array data of the Excel file created in the above creating step into an input unit of a verification program; allocating Excel file data to an input port of the BCM; converting the Excel file into a header file that can be compiled by a microcomputer of the BCM and compiling the header file together with software of the BCM; applying power to the BCM using an on/off control of a power supply unit and allowing input conditions to be inputted to the BCM by means of the inserted header file; allowing a relevant output signal to be generated by the BCM and storing the relevant output signal in an output unit; allowing the output unit to automatically output a test result and comparing the output result with a predetermined result to determine whether the BCM is acceptable or not; extracting a cause factor of problem occurrence through an analysis scheme; and finding an error of the software of the BCM using the cause factor of the problem occurrence. - View Dependent Claims (8, 9)
