The ever-increasing complexity and cost of automotive electrical systems are driving the change in automotive electronics development from traditional approaches to model-based methodology and processes. In this paper, the authors have described a model-based software development process particularly suitable for dealing with changes to existing designs, or 'feature changes' type of projects. The new process and methodology involves creating 'executable' requirements and functional models, generating test scenarios and/or cases, using the test cases for clarifying customer requirement specifications (which often come with a certain degree of incompleteness, inaccuracy, ambiguity, and even contradiction), using the clarified test cases for testing at various levels (such as the 'in-the-loop' tests at model, software, and hardware levels), and verifying the test results captured from the proprietary automatic test equipment. All of these tasks have been carried out either by directly employing the modeling tools Simulink /Stateflow from the Mathworks, or by using the utilities that have been developed in-house in the Matlab environment. The test scenarios/cases that play the central role in this model-based process are created, supplemented, modified and maintained throughout the product development life-cycle spanning from the 'requirement clarification' stage to vehicle validation. The authors have successfully applied this development process to production projects and found that the process is especially suitable to body electronics products development.
