Since several years Mercedes-Benz integrates simulation and comprehensive tests with a high degree of automation in the development process of automatic transmissions. This process has been continuously improved and extended. Recently also first suppliers and engineering service providers have been integrated in this process. In this paper we present the current state of the development process and the corresponding tool chain. As an application example, we use a dual-clutch transmission (DCT) for passenger cars currently under development at Mercedes-Benz. The work process is centered around a virtual integration (SiL) platform, here Silver. This enables to perform significant validation, test and analysis steps earlier than in traditional test development setups and that on highly available standard PCs available for each engineer participating in the project. When problems are found, the SiL platform provides a comfortable analysis and debugging environment. The investment in building and maintaining the SiL platform proved to be well justified by speed-ups due to shorter development cycles. The presented approach to system validation based on automated test generation with TestWeaver proved to be particularly useful. The AUTOSAR standardization of the software architectures will hopefully contribute in this direction. We expect and support also more steps toward a standardisation of the development tools and processes, including the SiL virtual integration platforms - an effort also followed in the Modelisar project.
