Thesis in the field of development of an AI-based component protection Full-time

Aufgaben To further optimize the range of electrically powered vehicles, the permanently excited synchronous machine (PSM) on the front axle is equipped with a disconnect unit (DCU). This intelligent disconnection system makes it possible to decouple the front axle fully automatically and depending on the situation. This measure reduces drag losses to a minimum and thus contributes to extending the range by only using the rear axle for the drive (source: Mercedes EQE SUV with disconnect unit – JESMB)
However, certain driving situations can lead to increased mechanical stress, which could potentially affect the DCU. To prevent this, the DCU must be opened proactively. The current approach is based on a logic-based method. However, the implemented algorithm occasionally leads to unnecessary openings (false positives) of the DCU, which can affect the lifetime
The aim of this work is therefore to investigate when it makes sense to use AI systems instead of conventional approaches in the powertrain. To this end, machine learning is to be used to optimize the opening behavior of the DCU and limit it to driving situations that are actually relevant. This could be achieved, for example, by taking other relevant features into account. Finally, the extent to which the existing analytical approach can be replaced or supplemented by an AI-based model will be evaluated
The work includes the following tasks:

• Familiarization with the use case and the logic already implemented
• Selection of additional input signals that may be relevant for the DCU opening
• Formulation of requirements for recording measurement data
• Selection and implementation of a suitable machine learning method with a focus on recurrent neural networks
• Validation and documentation of the results

The final topic is determined in consultation with the university, you and us
