摘　　要：为解决汽车电控系统需求开发过程中需求描述模糊不清、理解不一致问题,结合实际研发项目及CMMI-3等级认证过程的经验,提出了一种基于可视化分析模型的需求开发方法。首先,将复杂的汽车电控系统进行层级划分,从客户对整车顶层功能需求开始着手分析,通过用例场景建模定义系统与外部环境边界和交互关系,捕获顶层系统需求;然后,基于活动图和时序图可视化分析方法,对系统静态和动态行为进行细化分析,给出了不同层级需求挖掘思路及方法,并用需求图展示需求开发细节以及不同层级需求的追溯关系;最后,以触发柴油机颗粒捕集器DPF再生为研究案例,系统阐述了可视化分析模型的需求方法的应用过程,验证了所提方法的可行性与有效性,为汽车电控系统正向开发提供技术手段和指导建议。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 CMMI-3 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.
