  2. 6. Heavy-Duty Vehicle Platooning : Modeling and Analysis

    Author : Qichen Deng; Gunnar Flötteröd; Wilco Burghout; Clas Rydergren; KTH; []
    Keywords : Transportvetenskap; Transport Science;

    Abstract : Coupled with the growth of world economy, the demand for freight transport has escalated and will continue to do so. As the traffic intensity increases, the pressure on infrastructure, energy usage and environment becomes higher than ever. Meanwhile, the number of traffic accidents is also increasing year by year as a result. READ MORE

  4. 7. Fuel-Efficient Heavy-Duty Vehicle Platooning

    Author : Assad Alam; Karl H. Johansson; Roberto Horowitz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Platooning; Heavy-Duty Vehicle; Optimal Control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The freight transport industry faces big challenges as the demand for transport and fuel prices are steadily increasing, whereas the environmental impact needs to be significantly reduced. Heavy-duty vehicle (HDV) platooning is a promising technology for a sustainable transportation system. READ MORE

  5. 8. Fuel-Efficient Distributed Control for Heavy Duty Vehicle Platooning

    Author : Assad Alam; Karl Johansson; Ather Gattami; Roy Smith; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Heavy Duty Vehicle; Platooning; Fuel; Reachability; Game Theory;

    Abstract : Freight transport demand has escalated and will continue to do so as economiesgrow. As the traffic intensity increases, the drivers are faced with increasinglycomplex tasks and traffic safety is a growing issue. Simultaneously, fossil fuel usageis escalating. Heavy duty vehicle (HDV) platooning is a plausible solution to theseissues. READ MORE

  6. 9. Fuel-efficient and safe heavy-duty vehicle platooning through look-ahead control

    Author : Valerio Turri; Karl H. Johansson; Nathan van de Wouw; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; eco-driving; look-ahead control; dynamic programming; distributed model predictive control; optimal control; autonomous vehicles; Electrical Engineering; Elektro- och systemteknik; Vehicle and Maritime Engineering; Farkostteknik;

    Abstract : The operation of groups of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the overall aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Experimental tests conducted on a flat road and without traffic have shown that platooning has the potential to reduce the fuel consumption up to 10%. READ MORE

  7. 10. Heat transfer in ordered porous media with application to batteries

    Author : Amin Moosavi; Staffan Lundström; Anna-Lena Ljung; Tomas Muld; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; battery thermal management system; heat exchanger; cylindrical lithium-ion battery; cross-flow; analytical model; URANS model; thermal evaluation; wall effect; spacing effect; temperature distribution; Strömningslära; Fluid Mechanics;

    Abstract : Environmental concerns, resource depletion, energy security, technological advancements, and global policies are just a few of the variables influencing the global energy perspective. In the case of technological advancement, lithium batteries play a key role in the development of a more sustainable energy infrastructure. READ MORE
