New approaches in the software development for automotive systems

This paper presents a methodology for computer-tool-assisted development of functions realised by mechatronic in the car. Because of increasing complexity the developer requires a set of methods and tools that cover the whole development process. We show how the requirements for the software coming a from systems engineering can be considered. We present here a seamless process without manual interfacing that contains adaptations of the OO method and automotive specific extensions. We show how strong analysis helps to get a consistent understanding of the whole system. Hardware independent and executable specifications of the models help to design and validate the algorithms. From these specifications automatic coding can be generated. Virtual integration helps to design complex, distributed systems and find an optimal solution for costs and performance without having the hardware. We present a seamless tool chain that covers all steps including analysis, specification, and virtual integration without loss of information between the development phases.
