Description

Technical Field

[0001] The present invention relates to the technical field of automobile development, and in particular to a whole vehicle development interface maturity management and control system and method and a program product. Background Art

[0002] In the field of automobile manufacturing, as people demand higher quality in automobiles, product quality has become the foundation for the success of a new model project, and ensuring that each stage of the development of a new model project (planning-engineering-manufacturing-marketing) achieves the set goals is the key to ensuring product quality. In the development process of a new model project, the collaborative development of multiple systems of various disciplines is involved. Functional integration is achieved between various systems through a large number of parts interfaces. The design progress of the parts interfaces directly affects the development progress of the new model project. Therefore, the maturity control of each interface of the new model development project is an important part of the new model development project management. Continuously improving the efficiency of maturity control is of great significance to the successful implementation of the new model project.

[0003] At present, in the development process of new vehicle models, the maturity control of the interfaces of various components of new vehicle model development projects mainly relies on the experience judgment and manual statistics of designers. In particular, each car involves thousands of components, and each component contains a variety of information, including product component definition information, data model information, and drawing information. As a result, the calculation, monitoring, and management of the maturity of the interfaces of various components in new vehicle model development projects are relatively difficult. There is a lack of standard maturity calculation methods and management processes, and there is a lack of forward analysis capabilities for the maturity of the interfaces of various components, resulting in low work efficiency.

[0004] In order to eliminate the lagging of component interface design due to the non-standardized component interface maturity control methods in the development process of new vehicle model projects, which leads to limited component interface development, technical personnel in this field have been seeking effective control methods for the maturity of vehicle component interfaces, so as to achieve quantitative evaluation of the maturity of vehicle component interfaces, improve the accuracy and efficiency of component interface management in the development process of new vehicle model projects, and ensure the consistency and reliability of component interface quality.
