  1. 6. The Compression of IoT operational data time series in vehicle embedded systems

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

    Författare :Renzhi Xing; [2018]
    Nyckelord :Data compression; Data transmission; Time series data; IoT; CAN; Vehicle connectivity; Datakomprimering; Dataöverföring; Tidsseriedata; IoT; CAN; Uppkopplade fordon;

    Sammanfattning : This thesis examines compression algorithms for time series operational data which are collected from the Controller Area Network (CAN) bus in an automotive Internet of Things (IoT) setting. The purpose of a compression algorithm is to decrease the size of a set of time series data (such as vehicle speed, wheel speed, etc. LÄS MER

  3. 7. Data Aggregation in Time Sensitive Multi-Sensor Systems : Study and Implementation of Wheel Data Aggregation for Slip Detection in an Autonomous Vehicle Convoy

    Master-uppsats, KTH/Mekatronik

    Författare :Hanna Hellman; [2017]
    Nyckelord :slip detection; cooperative CPS CO-CPS ; data aggregation; wheel data aggregation; vehicle velocity estimation; platooning; weighted adaptive average;

    Sammanfattning : En övergång till bilar utrustade med avancerade automatiska säkerhetssystem (ADAS) och även utvecklingen mot självkörande fordon innebär ökad trafik på den lokala databussen. Det finns således ett behov av att både minska den faktiska mängden data som överförs, samtidigt som värdet på datat ökas. LÄS MER

  4. 8. Information filter based sensor fusion for estimation of vehicle velocity

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Michael Refors; [2016]
    Nyckelord :;

    Sammanfattning : In this thesis, the possibility to estimate the velocity of a Heavy-duty vehicle (HDV) based on the Global Positioning System (GPS), an Inertial Measurement Unit (IMU) and the propeller shaft tachometer is investigated. The thesis was performed at Scania CV AB. LÄS MER

  5. 9. Self-Adaptive Algorithm for Warehouse Truck Speed Measurement with Accelerometer

    Master-uppsats, KTH/Elektrisk energiomvandling

    Författare :Shuqi Zhao; [2015]
    Nyckelord :Vehicle speed; self-adaptive algorithm; warehouse trucks; accelerometer; Fordonshastighet; självanpassande algoritm; lagertruckar; accelerometer;

    Sammanfattning : Warehouse trucks are now a practical equipment for lifting and moving goods in warehouses. The working situation for warehouse trucks is complicated. Spilling of machine oil or liquid product leads to low friction coefficient of the floor. Warehouse floors are normally made of concrete. LÄS MER

  7. 10. Investigation of the transient nature of rolling resistance on an operating Heavy Duty Vehicle

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Petter Lundberg; [2014]
    Nyckelord :Rolling resistance; Air drag; Heavy Duty Vehicles; Vehicle dynamics; Complete vehicle test; Coastdown; Effective radius; ACEA; Pneumatic tires; Driving resistances; Energy efficiency; Rullmotstånd; Luftmotstånd; Tunga fordon; Fordonsdynamik; Helfordonstest; Utrullningstest; Effektiv radie; ACEA; Pneumatiska däck; Körmotstånd; Energieffektivitet.;

    Sammanfattning : An operating vehicle requires energy to oppose the subjected driving resistances. This energy is supplied via the fuel combustion in the engine. LÄS MER
