SEMAS – System Engineering Methodology for Automated Systems | The world described in layers

Abstract:
The development and provision of functions and systems in the context of "autonomous driving" is highly complex. With each new generation and with an increasing SAE level, more and more concepts and solutions are required. As a result of the technical and functional complexity and the abundance of regulations and standards, an ever-increasing degree of integration between the end customer, the vehicle manufacturers and their suppliers becomes necessary. Also, the development teams within these organizations have reached a size that requires a dedicated documentation and communication structure. Automotive SPICE essentially provides an applicable and efficient process description, but leaves open the concrete methodology for creating the content. The methodology presented here describes in detail how model-based the function and performance of "Automated Driving Systems" can be analyzed and used to derive architectures. The methodology pursues a holistic approach that covers the development process from end-customer requirements to implementation in hardware and software. This is done in a SysML / UML modeling environment in conjunction with a requirement management tool, in which the content is then linked to the ASPICE processes.
