Engineering change management system and BOM system data integration method

The invention relates to the technical field of automobile control, and provides an engineering change management system and BOM system integration method comprising the following steps: S1, inputting data in an engineering change management system, the input data comprising a matching field and update data, and matching a corresponding scene based on the matching field; S2, searching target data conforming to the matching field in the corresponding scene data, and changing the target data to form changed data; and S3, auditing the changed data, and synchronously updating the audited data to the BOM system after the data passes the auditing. The change information of the BOM system comes from the engineering change management system instead of manual input, and the published change data source is unique, so that the data consistency of the BOM system and the engineering change management system can be realized; the engineering change management system is suitable for change of multiple scenes, and therefore t
