    Nyckelord :Dimensionality Reduction; Autoencoder; Artificial Neural Network; Embeddings; Powertrain; Predictive Maintenance;

    Sammanfattning : Predictive Maintenance (PM) has been increasingly adopted in the Automotive industry, in the recent decades along with conventional approaches such as the Preventive Maintenance and Diagnostic/Corrective Maintenance, since it provides many advantages to estimate the failure before the actual occurrence proactively, and also being adaptive to the present status of the vehicle, in turn allowing flexible maintenance schedules for efficient repair or replacing of faulty components. PM necessitates the storage and analysis of large amounts of sensor data. LÄS MER

  3. 3. Co-Simulation of Engine Model and Control System with focus on Turbocharger Model

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Martin Wadner; [2020]
    Nyckelord :Co-simulation; Turbocharger; Engine Model; Waste Gate; Control System; Turbine Model; Simulink; GT-SUITE;

    Sammanfattning : The demands on heavy duty vehicles is constantly raising with government legislations on CO2 emissions becoming stricter and increasing customer demands. A continuous search for new methods and tools is a crucial element in finding more performance and lower emissions, which are prerequisites for heavy duty vehicles of the future. LÄS MER

  4. 4. Time dependent modeling of turbocharger failure using machine learning

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Felix Liljefors; [2020]
    Nyckelord :;

    Sammanfattning : Data-driven predictive vehicle maintenance can in principle reduce the risk of costly breakdowns, damaged cargo, and increased emissions due to faulty components. However, implementing a cost efficient predictive maintenance policy is far from trivial. LÄS MER

  5. 5. Assessment of a One Dimensional Loss Model For The Compressor of a Turbocharger

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI); KTH/Skolan för teknikvetenskap (SCI)

    Författare :Laszlo Vimlati; Hugo Essinger; [2020]
    Nyckelord :;

    Sammanfattning : This report sets out to implement and asses a one-dimensional loss model for centrifugal compressors. The loss model which has been evaluated is the model by Oh et al. (1997) [1]. The implementation was completed using iterative methods implemented in Matlab. LÄS MER
