For the BMW Group, IABG has developed a complex test bench, used to optimize functions and validate concepts for active steering systems. Failure simulation and test automation were implemented by means of dSPACE technology. The hardware-in-the-loop (HIL) system test bench has proved itself an efficient tool, from the concept phase to production development, and right through to product support during start of production. Essential aspects of function validation and fail-safe testing are no longer covered by test drives, but put on the test bench instead – with additional benefits such as enhanced reproducibility, efficiency and economy.
