摘要

Over the past decades, the adoption of electronic systems for the manufacturing of automotive vehicles has been exponentially popularized. This growth has been driven by the premium automobile sector where, presently, diverse electronic systems are used. These electronic systems include systems that control the engine, transmission, suspension and handling of a vehicle; air bag and other advanced restraint systems; comfort systems; security systems; entertainment and information (infotainment) systems. In systems terms, automotive embedded electronic systems can now be classified as a System of Systems (SoS). Automotive systems engineering requires a sustainable integration of new methods, development processes, and tools that are specifically adapted to the automotive domain. Model-based design is one potential methodology to carry out design, implement and manage such complex distributed systems, and their integration into one cohesive and reliable SoS to meet the challenges for the automotive industry. This research was conducted to investigate the model-based design of a 4×4 Information System, within an automotive electronic SoS. Two distinct model-based approaches to the development of an automotive electronic system are discussed in this study. The first approach involves the use of the Systems Modelling Language (SysML) based tool ARTiSAN Studio for structural modelling, functional modelling and code generation. The second approach involves the use of the MATLAB based tools Simulink and Stateflow for functional modelling, and code generation. The results show that building the model in SysML by using ARTiSAN Studio provides a clearly structured visualization of the 4×4 Information System from both structural and behavioural viewpoints of the system with relevant objects. SysML model facilitates a more comprehensive understanding of the system than the model built in Simulink/Stateflow. The Simulink/Stateflow model demonstrates its superior performance in producing high quality and better efficiency of C code for the automotive software delivery compared with the model built in ARTiSAN Studio. Furthermore, this Thesis also gets insight into an advanced function development approach based on the real-time simulation and animation for the 4×4 Information System. Finally, the Thesis draws conclusions about how to make use of model-based design for the development of an automotive electronic SoS.
