An integrated methodology to system design and simulation for electric vehicles based on X language

To design and develop electric vehicles, traditionalmodel-based system engineering methodologies need to combine system-oriented SysML and physics-oriented Modelica or Simulink. However, cross-language and cross-platform integration design can lead tomodel inconsistencies and increase the learning cost for modelers, while also reducing system development efficiency. To address these issues, this paper proposes the use of X language for model-based systems engineering (MBSE) to realize integrated modeling and simulation of functional and physical characteristics in the linear driving scenarios of electric vehicles. Based on the analysis of the requirements for this scenario, an integrated model is established using X language, including a logical model for system architecture based on functional requirements and a physical model based on performance requirements, and verified in XLab. This X language-based integrated methodology to system design and simulation can quickly verify the coordination of functional and performance requirements for electric vehicles. It can also help designers better identify system design problems holistically and enable them to make timely corrections. This X language-based integrated methodology to system design and simulation provides a new theoretical and methodological reference for designers in different fields.
