I korthet

This thesis position involves developing and evaluating a machine-learning framework for identifying health states in a heavy-duty vehicle’s thermal management system. The work will focus on optimal control strategies using look-ahead information to minimize energy consumption and improve performance, comparing different estimation methods and classification approaches.

Ansvarsområden

Develop and evaluate a machine-learning framework to identify five health states in a heavy-duty vehicle’s active cooling refrigerant system.
Compare two ways of estimating conditions before the expansion valve: an observer-based estimate and direct sensor measurements across TXV and EXV systems.
Prepare and qualify test data, establish reliable fault labels, and develop features based on the system’s physical behaviour.
Compare different classification approaches and assess their ability to distinguish faults such as low refrigerant charge, expansion-valve underfeeding or overfeeding, and compressor degradation.
Test how well the models generalize to unseen hardware units and test sessions.
Calibrate confidence levels and define when a diagnosis should be reported as inconclusive.
Provide recommendations for further validation toward production use.

Familiarity with data analysis and interpretation.
Proficiency in relevant software tools such as Python and Simulink.
Ability to work independently and as part of a team.
Strong analytical and problem-solving skills.
