  1. 31. Transportation Mission-Based Optimization of Heavy Combination Road Vehicles and Distributed Propulsion, Including Predictive Energy and Motion Control

    Författare :Toheed Ghandriz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automation; electrified propulsion; long combination vehicles; electromobility; propulsion system tailoring; automated driving systems; optimal control; single-track and two-track vehicle models; predictive energy management and vehicle stability; motion control; longer heavier vehicles; vehicle stability; optimal energy management; total cost of ownership; optimization; transportation mission; heterogeneous heavy vehicle fleet; fleet sizing;

    Sammanfattning : This thesis proposes methodologies to improve heavy vehicle design by reducing the total cost of ownership and by increasing energy efficiency and safety. Environmental issues, consumers expectations and the growing demand for freight transport have created a competitive environment in providing better transportation solutions. LÄS MER

  2. 32. Vehicle dynamic analysis of wheel loaders with suspended axles

    Författare :Adam Rehnberg; Annika Stensson Trigell; Lars Drugge; Peter Eriksson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hjullastare; arbetsmaskin; fordonsdynamik; fordonsteknik; Vehicle engineering; Farkostteknik;

    Sammanfattning : The wheel loader is a type of engineering vehicle used primarily to move crude material over shorter distances. As the vehicle is designed without wheel suspension, wheel loader drivers are exposed to high levels of whole body vibration which influences ride comfort negatively. LÄS MER

  3. 33. Virtual Human Characters for Autonomous Vehicle-to-Pedestrian Communication

    Författare :Alexandros Rouchitsas; Håkan Alm; Jessica Körning-Ljungberg; Jonas Lundberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; external human-machine interfaces; pedestrian acknowledgement; vehicle intention; traffic safety; traffic flow; gaze direction; facial expression; Engineering Psychology; Teknisk psykologi;

    Sammanfattning : Pedestrians base their street-crossing decisions on both vehicle-centric cues, like speed and acceleration, and driver-centric cues, like gaze direction and facial expression. In the future, however, drivers of autonomous vehicles will be preoccupied with non-driving related activities and thus unavailable to provide pedestrians with relevant communicative cues. LÄS MER

  4. 34. Dynamic Vehicle-Track Interaction of European Standard Freight Wagons with Link Suspension

    Författare :Per-Anders Jönsson; Sebastian Stichel; Evert Andersson; Jerzy Piotrowski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; railway; freight wagon; running gear; link suspension; laboratory test; ; stiffness; dry friction; hysteresis; simulation; vehicle-track interaction; multibody; simulation; MBS; Vehicle engineering; Farkostteknik;

    Sammanfattning : The link suspension is the most prevailing suspension system for freight wagons in Central and Western Europe. The system design is simple and has existed for more than 100 years. However, still its characteristics are not fully understood. LÄS MER

  5. 35. Vehicle Dynamics Control for Active Safety Functions using Electrified Drivelines

    Författare :Adithya Arikere; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver assistance systems; intersection accidents; torque vectoring; optimal control; rear- end collisions; speed control; active safety; vehicle dynamics; electrified drivetrain; obstacle avoidance with oncoming traffic;

    Sammanfattning : Studies have shown that even considering pledges and commitments made by various governments and organisations, the growth in electrified vehicle sales is likely to be insufficient to reduce CO2 emissions for mitigating global warming. Some form of added incentive is needed that can help drive electrified vehicle sales in the open market. LÄS MER
