Abstract: In the field of automotive electronic control system design, in order to solve a series of problems caused by the systematic development of traditional V mode by text, such as the inconsistency between design and original source requirement, the poor visualization analysis of scheme changes and risk assessment, and the difficulty of modular reuse of product variants, a model-based graphical representation development method of system engineering is proposed. Based on the V process development model, this method refines and decomposes the system requirement analysis and architecture design, builds the demand model, functional model, logical and physical architecture design model, and forms a set of formal modeling methods for the research and development of automotive electronic control system, and describes the electronic control system comprehensively and intuitively from the perspective of multiple views. Taking the vehicle cruise control function as a case study, this method is used to analyze the visual modeling of the cruise control system, which verifies the feasibility and effectiveness of the proposed method in the field of automotive electronic control system, and provides suggestions for the efficient development of automotive electronic control system.

摘要： 在汽车电控系统设计领域，为了解决传统 V 模式以文本方式进行系统性开发带来的设 计与本源需求不一致、方案变更与风险评估可视化分析差、产品变型模块化复用难等一系列 问题，提出了一种基于模型的系统工程图形化表达开发方法。该方法以 V 流程开发模式为原 型，对系统需求分析与架构设计进行细化与分解，构建需求模型、功能模型、逻辑与物理架 构设计模型，形成一套针对汽车电控系统研发的形式化建模方法，采用多视图角度对电控系 统进行全面而直观描述。以汽车定速巡航功能为研究案例，使用这种方法进行定速巡航系统 可视化建模分析，验证了所提出的方法在汽车电控领域的可行性及有效性，为汽车电控系统 的高效研制提供方案建议。
