The article presents the construction and functional properties of a research test bench for a passenger car powertrain with an automatic transmission. This test bench enables simulation-based laboratory testing. Its functionality allows for the study of powertrain dynamics during transient processes. It can also be used for testing an eddy-current brake used as a retarder, as well as for testing passenger car disc brakes.The article also presents important safety systems implemented in this test bench. Research on longitudinal vehicle dynamics and powertrain dynamics can be conducted in various ways – through traction tests, proving ground tests, laboratory tests, as well as model-based research using computer simulation [1]. The author of this article presents a test bench that allows for research on a real powertrain under simulated powertrain load conditions. The form of simulation can be twofold, concerning both predictive simulation and playback simulation. (…)
