Due to new software architectures, modern vehicles are becoming increasingly complex and therefore are frequently referred to as software-defined vehicles. Especially in the area of advanced driver assistance systems (ADAS) and autonomous driving functions, the operational design domain (ODD) in particular contributes to high system complexity. Therefore, the development, validation and subsequent updating of related functions can be realized by means of real-world road tests only to a very limited extent and in some cases are not possible at all or economically unfeasible.

    By contrast, the utilization of virtual vehicle development makes it possible to test and validate driving functions in all conceivable situations. With it, consistent validation in every development stage through to real-world testing of the developed software based on reproducible tests can be achieved. If the relevant subsystems as in the case of SIL simulation are available in fully virtualized form, a very large number of test kilometers can be run due to the high level of parallelization. In that case, parallelization can take place in the cloud, for instance through scalable computing power.

    To successfully integrate this approach into existing processes, thus enabling efficient development and testing work, a superordinate level for easy access to simulation is necessary. That level must offer the opportunity to intuitively manage and version the data volumes, the simulation models and the software. As a tool for workflow management in the simulation, VIRTO supports a large number of test methods such as MIL/SIL/HIL/VIL, open-loop and closed-loop tests as well as proving ground tests with real-world targets.

    All data, test runs and results can be used again for each development stage, which substantially minimizes the development effort and expense. Following its market launch and up until the vehicle’s end of life, this process can be transferred seamlessly to the development of OTA updates.
