BMW – Highly Dynamic Test Benches

Performing calibration tasks on a real test vehicle fleet can be time-intensive and expensive. BMW is able to cut its development times and costs considerably by shifting some of its calibration work to test benches. This requires detailed simulation of real vehicle behavior – for example, in calibrating vehicle dynamics functions on an engine test bench. BMW’s solution is highly dynamic engine test benches that can precisely mimic longitudinal vehicle dynamics in the relevant frequency range. The simulation systems of the test benches include powerful dSPACE real-time hardware and software.
