New digital ecosystems are springing up in all walks of life, using software and data to link together pre-existing products and processes. That is all well and good but, as the Fraunhofer-Institute for Experimental Software Engineering (IESE) has pointed out, integrating these components and systems still poses a key challenge, as it increasingly has to be done dynamically and on the fly. Naturally, safeguarding and testing are particularly important for automated systems that make safety-relevant decisions and can, in extreme cases, mean the difference between life and death. One pertinent example would be a vehicle platform that can adopt and integrate driving functions dynamically. That is why Fraunhofer IESE is exhibiting FERAL at the Fraunhofer Group Pavilion in Hall 27 at CEBIT 2018.
Taking automotive platforms as an example application, Fraunhofer IESE is demonstrating how real and virtual worlds can be linked and how the FERAL simulation framework can be used to thoroughly test individual software functions and their complex interactions. Model autonomous vehicles that visitors can track virtually on a monitor demonstrate how various driving functions can be integrated. Experts call these virtual hardware-in-the-loop tests.
The FERAL solution from Fraunhofer IESE is a simulation platform with various components that supports the integration of even complex, heterogeneous scenarios into a test scenario. It can also be used to systematically check characteristic values in a protected virtual space with the help of digital twins. One example scenario could be ensuring that pedestrian recognition systems work properly or that two functions from different manufacturers work together seamlessly. Since no physical test setups and experiments are needed, costs can be cut and specific situations that only occur rarely in reality or that involve a lot of risk can also be replicated.
