基于SysML的车辆信息系统设计

针对目前车辆信息系统缺乏有效设计方法的现状，结合新时期车辆信息系统的特点，提出了一种基于SysML的车辆信息系统设计方法。该方法明确了车辆信息系统设计过程的阶段和产物，并通过标准建模语言SysML的运用，用模型来支持系统的设计和有效性验证。该方法在智能巡航系统的设计中得到了运用。实践结果表明，该方法不仅能够自顶向下完整地设计系统、利用可视化的语言准确清晰地描述系统，而且能够在系统设计层面对系统功能逻辑和数据流进行动态仿真和迭代验证。该方法能够较好地指导新时期车辆信息系统的设计过程，满足信息系统的设计要求。

RESEARCH ON DESIGN OF VEHICLE INFORMATION SYSTEM BASED ON SYSML

For lack of effective design methods in field of vehicle information system, the new design method combined with the characteristics of the new era of vehicle information system and using SysML is proposed. This method clearly builds an effective design process and carry out system simulation through the use of standard modeling language SysML . Its feasibility is demonstrated using the example of the Intelligent Cruise System, which is modeled and simulated in SysML. The simulation results show that this method can not only design and describe the information system synthetically and clearly by using visualized language , but also accomplish the dynamic simulation and iterative verification of the system function logic and data flow on the level of system design. This method can effectively guide the design of the new era of vehicle information system and meet the design requirements.
