A Methodology for Model Based Development of Application Software Modules Exemplified by Radar Based Parking Systems

摘要

This paper addresses a methodology for the development of driver assistance systems. As an example the development of parking systems is described in detail. Throughout the paper the complete system including sensors, ECU and software is considered in order to provide better understanding of the overall development activities in each state of development. A model based development approach is chosen for the early evaluation of the whole system. Graphical models are used throughout the process which is also advantageous for the extraction and the systematic validation of sub modules. The models are both used for the preparation of decisions in functional or software architecture and for testing and integration strategies. For software modules containing core function applications the tool-supported development is presented, starting from basic ideas of new functionalities up to and including automatically generated production code for electronic control units.
