  2. 1. Look-ahead Control of Heavy Vehicles

    Author : Erik Hellström; Lars Nielsen; Jan Åslund; Lino Guzzella; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automotive control; dynamic programming; predictive control; fuel-optimal control; long haulage truck; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Abstract : Trucks are responsible for the major part of inland freight and so, they are a backbone of the modern economy but they are also a large consumer of energy. In this context, a dominating vehicle is a truck with heavy load on a long trip. READ MORE

  4. 2. Fuel-Efficient Look-Ahead Control for Heavy-Duty Vehicles with Varying Velocity Demands

    Author : Manne Held; Jonas Mårtensson; Oscar Flärdh; Ardalan Vahidi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; look-ahead control; optimal control; powertrain control; advanced driver assistance systems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The fuel consumption of heavy-duty vehicles can be reduced by using information about the upcoming road section when controlling the vehicles. Most manufacturers of heavy-duty vehicles today offer such look-ahead controllers for highway driving, where the information consists of the road grade and the velocity only has small variations.

  5. 3. Look-ahead Control of Heavy Trucks utilizing Road Topography

    Author : Erik Hellström; Lars Nielsen; Torkel Glad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; predictive control; dynamic programming; Automatic control; Reglerteknik;

    Abstract : The power to mass ratio of a heavy truck causes even moderate slopes to have a significant influence on the motion. The velocity will inevitable vary within an interval that is primarily determined by the ratio and the road topography. READ MORE

  6. 4. Fuel Optimal Powertrain Control for Heavy Trucks Utilizing Look Ahead

    Author : Maria Ivarsson; Lars Nielsen; Jan Åslund; Jan Wikander; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The road topography in highways affects the powertrain control of a heavy truck substantially since the engine power is low in relation to the vehicle weight. In large road gradients constant speed is not possible to keep, which would have been beneficial otherwise, and in some uphills shifting gears becomes inevitable. READ MORE

  7. 5. Optimal Speed and Powertrain Control of a Heavy-Duty Vehicle in Urban Driving

    Author : Manne Held; Jonas Mårtensson; Jonas Fredriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; optimal control; heavy-duty vehicles; trucks; powertrain control; fuel; Electrical Engineering; Elektro- och systemteknik;

    Abstract : A major challenge in the transportation industry is how to reduce the emissions of greenhouse gases. One way of achieving this in vehicles is to drive more fuel-efficiently. READ MORE
