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.
