  1. 1. Network Traffic Regulator for Diagnostic Messages in Modular Product

    Master-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :Nikhil Thakrar; [2017]
    Nyckelord :Controller Area Network; CAN; Diagnostics; Scania; UDS; KWP; OBD; J1939; Network regulator; bandwidth management; Token Bucket; Traffic shaping; vehicle; bit stuffing; OSI model; arbitration;

    Sammanfattning : The aim of this thesis project is to explore a network traffic regulator using bandwidth management techniques that regulates data traffic with the objective to use the network bandwidth to its maximum capacity while ensuring that the network is not overloaded. The bandwidth in the existing network architecture is shared between two co-existing, distinct data flows for on-board communication and diagnostic communication in an in-vehicle network. LÄS MER

  3. 2. Exhaust Analyser for Simplified Emissions Testing on Heavy Duty Vehicles

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Jonas Eriksson; Simon Fagerholm; [2014]
    Nyckelord :;

    Sammanfattning : Over the years the regulations on emissions from heavy duty vehicles have become stricter. Emission measurements during development are therefore done by the manufacturers in order to check compliance in an early stage. This is a time demanding process due to complicated installation and operation of the test equipment. LÄS MER

  4. 3. Workshop Methods for Troubleshooting the Performance of the After-treatment system

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :André Åkerberg; Daniel Törnroos; [2013]
    Nyckelord :;

    Sammanfattning : New legislations are constantly arising in Europe that puts stringent restrictions on the emissions coming from heavy-duty vehicles. The latest one is the Euro VI that has tough limits on both nitrogen oxides (NOx) and particulate matter (PM). LÄS MER

  5. 4. Methods for Residual Generation Using Mixed Causality in Model Based Diagnosis

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Magnus Johansson; Johan Kingstedt; [2008]
    Nyckelord :model based residual generation; derivative estimation; structural methods;

    Sammanfattning : Several different air pollutions are produced during combustion in a diesel engine, for example nitric oxides, NOx, which can be harmful for humans. This has led to stricter emission legislations for heavy duty trucks. The law requires both lower emissions and an On-Board Diagnosis system for all manufactured heavy duty trucks. LÄS MER

  7. 5. Diagnosis of a Truck Engine using Nolinear Filtering Techniques

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Fredrik Nilsson; [2007]
    Nyckelord :particle filter; diagnosis; extended Kalman filter; likelihood; cusum;

    Sammanfattning : Scania CV AB is a large manufacturer of heavy duty trucks that, with an increasingly stricter emission legislation, have a rising demand for an effective On Board Diagnosis (OBD) system. One idea for improving the OBD system is to employ a model for the construction of an observer based diagnosis system. LÄS MER
