HIL System Test Stands for Active Steering Systems for BMW

 With the delivery of two turnkey system test stands for active steering systems (EPS: Electric Power Steering) and (AFS: Active Front Steering) and the official handover on 18. Feb. 2003 at BMW, IABG achieved an important success in the Mechatronic Systems sector.

The test stand technology developed during this project represents an innovation in the Intelligent Test Technology field. To be emphasised are the online-communications with a complex integrated control unit, the applications and diagnosis possibilities and the linking to a stand-alone-HIL-simulator.

The system test stands serve to optimise the functions and assure the concept for active steering systems as part of series development. The major aim is to relocate important parts of the functional development and Fail-Safe investigations from the running tests to the test stand and thereby to make full use of the important advantages of tests on test stands such as reproducibility and time efficiency.
