This paper introduces the characteristics of Model-Based Software Development and SCADE high-security embedded system development tools, and studies its main workflow and software engineering methods. For the rapid development of automotive electronics, a model-based theory and SCADE tools were used to design and implement a vehicle auto-driving assistance system, including system architecture design, system function model design, system user interface design, etc. Finally, the system was simulated with joint functions and a verification test. The result shows that the functional requirements are all achieved, the test coverage reaches 100%, and the corresponding software documentation and code and executable files are generated. The complete SCADE model development method and process were explored.
