  1. 1. Diagnostics of Intermittent Errors

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Niklas Lindborg; [2021]
    Nyckelord :Intermittent errors; diagnostics; knowledge gap; fault isolation; Intermittenta fel; diagnostik; kunskapslucka; felisolering;

    Sammanfattning : Intermittent faults/errors are infamous for being among the most challenging errors to diagnose. It is estimated that more than 80% of the total number of errors in real systems are intermittent errors. Previous research on intermittent errors suggests that they are the prelude to permanent faults. LÄS MER

  3. 2. Transformer decoder as a method to predict diagnostic trouble codes in heavy commercial vehicles

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

    Författare :Haris Poljo; [2021]
    Nyckelord :Diagnostic Trouble Codes; Deep Learning; Machine Learning; Neural Networks; Transformer Decoder; Felkoder; Djupinlärning; Maskininlärning; Neurala Nätverk; Transformer Decoder;

    Sammanfattning : Diagnostic trouble codes (DTC) have traditionally been used by mechanics to figure out what is wrong with a vehicle. A vehicle generates a DTC when a specific condition in the vehicle is met. This condition has been defined by an engineer and represents some fault that has happened. LÄS MER

  4. 3. Symptombaserad felsökning av tunga fordon : En systematisk metod för att sammankoppla kundsymptom med systemreaktioner

    Master-uppsats, Mälardalens högskola/Innovation och produktrealisering

    Författare :Alexander Törnqvist; Jesper Jansson; [2020]
    Nyckelord :Symptom-based troubleshooting; CBR; Case-Based-Reasoning; bayesian network; vehicle; truck; customer symptom; Symptombaserad felsökning; Case-Based-Reasoning; CBR; Bayesiska nätverk; kundsymptom; lastbil; tunga fordon;

    Sammanfattning : This thesis is about symptom-based troubleshooting of heavy vehicles. The existing troubleshooting system at Scania is adapted to handle errors based on electronic fault codes. This means that some faults, such as mechanical faults when sensors are missing, are difficult to troubleshoot. LÄS MER

  5. 4. Remote Diagnostics of Heavy Trucks through Telematics

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Truls Shanwell; Håkan Svensson; [2013]
    Nyckelord :;

    Sammanfattning : Fordonsdiagnostik blir mer och mer sofistikerad i takt med att antaletoch komplexiteten hos inbyggda fordonsdatorer växer. Datorstödd diagnos med hjälp av en PC som kör en diagnosapplikation är en nyckelfaktor inom reparation och underhåll. LÄS MER

  7. 5. Prediktering av komponenters mognad/kvalitet utifrån felkodsutfall

    Uppsats för yrkesexamina på avancerad nivå, Matematisk statistik

    Författare :Sophie Höglund; [2012]
    Nyckelord :mognad; kvalité; statistik; felkoder;

    Sammanfattning : This master thesis has been carried out at Scania R&D at the department of Powertrain Control System Development during the winter 2011/2012. The purpose of the thesis was to produce a method that with the result of troubles codes from the field testing would be able to say something about the maturation of a component, in this case the VGT, variable geometry turbocharger.
