  1. 1. Assessment of Telematic Systems for Road Freight Transport

    Författare :Gideon Mbiydzenyuy; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Transportation; telematics; architectures; analysis; optimization; clustering; net present value;

    Sammanfattning : The focus of this thesis is the assessment of telematic systems for road freight transport from a planning perspective. The aim is to support strategic decisions related to architectural choices for such systems, with the possibility to achieve synergies by supporting multiple telematic services. LÄS MER

  2. 2. Sensor Fusion for Smartphone-based Vehicle Telematics

    Författare :Johan Wahlström; Peter Händel; Erik Gudmundson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The fields of navigation and motion inference have rapidly been transformed by advances in computing, connectivity, and sensor design. As a result, unprecedented amounts of data are today being collected by cheap and small navigation sensors residing in our surroundings. LÄS MER

  3. 3. On Energy Management Strategies for Hybrid Electric Vehicles

    Författare :Lars Johannesson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

    Sammanfattning : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. LÄS MER

  4. 4. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes

    Författare :Lars Johannesson; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Energy Management; Powertrain Control; Predictive Control; Dynamic Programming; Vehicle Telematics; Hybrid Electric Vehicle; Hybrid Electric Powertrains;

    Sammanfattning : At the highest level in the powertrain control system in a hybrid electric vehicle an energy management controller interprets the driver’s pedal actions as a torque that is to be delivered at the powertrain output. The energy management controller distributes this torque between the engine and the electric machines and decides when to change gear and when to turn off the engine for pure electric propulsion.
