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

    Författare :Lars Johannesson; [2009]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

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

    Författare :Lars Johannesson; [2006]
    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

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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Johan Wahlström; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Gideon Mbiydzenyuy; Blekinge Tekniska Högskola.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Machine learning methods for vehicle predictive maintenance using off-board and on-board data

    Detta är en avhandling från Halmstad : Halmstad University Press

    Författare :Rune Prytz; Högskolan i Halmstad.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Vehicle uptime is getting increasingly important as the transport solutions become more complex and the transport industry seeks new ways of being competitive. Traditional Fleet Management Systems are gradually extended with new features to improve reliability, such as better maintenance planning. LÄS MER
