Abstract: Based on the digital mock up module in CATIA, this paper analyzes the problems in the vehicle general layout verification process, and proposes a vehicle general layout digital mock up intelligent verification method for the first time, including the three-dimensional vehicle model data integrity control and gap intelligent checking method. At the same time, a set of intelligent verification tools for vehicle data was developed based on this method. This tool effectively solves the problem of inconvenient and unsuitable application of foreign industrial software in key scenarios of domestic car companies. For example, the digital mock up module cannot perform the complete vehicle 3D model data integrity check, and the gap between pairs of specific name components cannot be batch checked. Apart from this, these tools also can solve the problem that the inspection results cannot be exported. This method greatly improves the efficiency and accuracy of the overall vehicle layout verification.
