Abstract
- In order to solve the problems of vague and inconsistent requirement descriptions and understanding during the development of electronic control systems, and taking into account the experience of actual research and development projects and the CMMI3 level certification process, a requirement development method based on a visual analysis model was proposed. Firstly, the complex automotive electronic control system was hierarchically divided, and the customer's top-level functional requirements of the vehicle were analyzed. The use case scenario modeling was used to define the system and the external environment boundary and interaction relationship to capture the top-level system requirements. Then, based on the visual analysis method of activity diagram and sequence diagram, the static and dynamic behaviors of the system were analyzed in detail, and the ideas and methods of requirement mining at different levels were given. The requirement diagram was used to show the details of requirement development and the traceability relationship of different levels of requirement. Finally, taking trigger diesel particulate filter DPF regeneration as a case study, the application process of the requirement method of visual analysis model was systematically expounded, and the feasibility and effectiveness of the proposed method were verified. Results provide technical means and guidance for the forward development of automobile electronic control system. [ABSTRACT FROM AUTHOR]
