Outline
The Intelligent Vehicle Cyber-Physical System (IVCPS) can control the operation trajectory of vehicles based on road and vehicle information resources in real time, which has great potential in reducing vehicle energy consumption. However, the current studies on Cloud-Based Predictive Cruise Control (CPCC) architecture ignore the feasibility of architecture implementation and application, without verifing the rationality of the architecture. To establish the links among architecture, application and verification, promote multi-domain and multi-disciplinary collaborative design, joint simulation as well as system integration in IVCPS, this paper proposes the modeling method of IVCPS based on Model-Based Systems Engineering (MBSE). Firstly, the overall layered architecture of IVCPS is constructed and the elements of each layer of the architecture are clarified. Then Systems Modeling Language (SysML) is utilized as the modeling tool and the Requirement analysis-Functional analysis-Logical analysis-Parametric calibration (RFLP) modeling framework is constructed. Finally, a typical scenario of CPCC system within IVCPS is taken as an example. The RFLP framework is utilized to model and analyze the requirements, functions, logics and parametric calibration of the CPCC system. The modeling results prove that MBSE can realize the unified modeling of the requirement analysis, function decomposition, logical architecture design and system parameter calibration of the CPCC system, promote simulation verification of the theoretical architecture of the CPCC system and be able to test and analyze the effectiveness of the CPCC architecture in optimizing the running trajectory and reducing fuel consumption of intelligent connected vehicles. This study lays a foundation for improving the interactivity, reusability and compatibility of IVCPS system modeling.
