Machine Learning-based realtime calibration of temperature prediction in transmission

Topic and Goal of the Thesis

Similarly to electric machines, gearboxes are also subject to thermal derating. An online state monitoring combined with suitable control strategy can prevent overheating and therefore prolong transmission lifetime. However, that requires highly precise models for temperature prediction incl. correct depiction of thermal inertia to be reliably used by operation strategy optimizer.

One way to increase prediction accuracy is by using machine learning. Therefore, the following thesis aims to develop a plug-andplay calibration algorithm using simulation and measurement data of an e-axle for a commercial vehicle.
