All test stands – internal combustion engines, electric motors, batteries, gearboxes and complete powertrains – installed at the Center for Mobile Propulsion use a multivalent real-time automation system to monitor and perform automated tests. This makes it possible to perform all control and regulation tasks under tough time constraints. In addition, safety functions and the recording of all measurement signals in high resolution with a 1kHz grid are integrated in the automation system.

It is possible to implement test sequences defined in advance in tabular or graphical form, which allow the measurement of transient temporal processes or condition-dependent measurement sequences. Furthermore, it is possible to test the component to be tested against a simulated environment such as a road simulation. The control of the accelerator pedal, gear changes and brake is done by a simulated driver, whereby speed profiles can be measured reproducibly.
The connection of recorded signals to the measurement data acquisition is carried out via standardized interfaces, the so-called "Engine & Signal Interface Box" in short EIB/SIB, whereby all variables, independent of the test object and the current research project, can be uniformly measured. The automation system is also modular and can be flexibly configured via test bench, test run and DUT-related parameters. This enables fast integration of measurement technology. Furthermore, the uniform mechanical and electrical interfaces enable an efficient and time-saving change of the DUT.
