  2. 1. Aerodynamics of two trucks driving in close-proximity

    Author : Johannes Törnell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; drag; aerodynamics; cab over engine; inter-vehicle distance; lateral offset; side wind; truck; platooning; yaw; close proximity; wake;

    Abstract : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. READ MORE

  4. 2. Aerodynamics of vehicle platooning

    Author : Johannes Törnell; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; close proximity; drag; platooning; cab over engine; aerodynamics; yaw; wake; side wind; truck; inter-vehicle distance; lateral offset;

    Abstract : Many factors are pushing automotive manufacturers to increase the efficiency of their fleets; some of these are legislative (requiring reduced greenhouse gas emissions) as well as ensuring sufficient range and power consumption in electric vehicles. An important part of improving the energy efficiency of road vehicles is reducing their aerodynamic drag. READ MORE

  5. 3. 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

  6. 4. Safety of Cooperative Automated Driving : Analysis and Optimization

    Author : Galina Sidorenko; Alexey Vinel; Johan Thunberg; Elisabeth Uhlemann; Högskolan i Halmstad; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platooning; Cooperative Intelligent Transportation System C-ITS ; Vehicle-to-Vehicle V2V communication; emergency braking; road safety; ITS-G5; IEEE 802.11p; automated driving;

    Abstract : New cooperative intelligent transportation system (C-ITS) applications become enabled thanks to advances in communication technologies between vehicles(V2V) and with the infrastructure (V2I). Communicating vehicles share information with each other and cooperate, which results in improved safety, fuel economy, and traffic efficiency. READ MORE
