  1. 6. Development of Methods for Automatic Design of Residual Generators

    Magister-uppsats, Institutionen för systemteknik

    Författare :Carl Svärd; Henrik Wassén; [2006]
    Nyckelord :model based diagnosis; residual generator; residual generation; structural analysis; causality; stability;

    Sammanfattning : Legislation requires substantially lowered emissions and that all trucks manufactured are equipped with an On-Board Diagnosis (OBD) system. One approach for designing an OBD system is to use model based diagnosis and residual generation. LÄS MER

  3. 7. Design and Evaluation of an Automatically Generated Diagnosis System

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Joakim Hansen; Jens Molin; [2006]
    Nyckelord :Model based diagnosis; Diagnosis performance; Evaluation;

    Sammanfattning : Throughout recent years, legislations concerning emission levels for vehicles have become more restrictive and will be even more restrictive in the future. In the recent European environmental standards, EURO 4 (2006) and EURO 5 (2008), further requirements have been added on top of low emission demands. LÄS MER

  4. 8. Distributed Fault Diagnosis for Networked Embedded Systems

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Dan Hallgren; Håkan Skog; [2005]
    Nyckelord :Distributed diagnosis; OBD; Fault isolation; Embedded systems; DTC;

    Sammanfattning : In a system like a Scania heavy duty truck, faultcodes (DTCs) are generated and stored locally in the ECUs when components, e.g. sensors or actuators, malfunction. Tests are run periodically to detect failure in the system. LÄS MER

  5. 9. Optimisation of a Diagnostic Test for a Truck Engine

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Petter Haraldsson; [2002]
    Nyckelord :Technology; threshold levels; OBD; residual; statistic; model; outliers; filtering; TEKNIKVETENSKAP;

    Sammanfattning : Diagnostic systems become more and more an important within the field of vehicle systems. This is much because new rules and regulation forcing the manufacturer of heavy duty trucks to survey the emission process in its engines during the whole lifetime of the truck. LÄS MER
