  2. 21. Characterisation and Utilisation of Steering Feel in Heavy Trucks

    Author : Malte Rothhämel; Lars Drugge; Joop Pauwelussen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Steering is next to braking the most important control feature of a road vehicle. The driver gives input through the steering wheel and the vehicle reacts in a certain way, which results in a transfer function between input and output. READ MORE

  4. 22. On Lateral Stability of Heavy Vehicle Combinations - Linking Accident Analysis and Vehicle Dynamics

    Author : Sogol Kharrazi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accident Analysis; Vehicle Dynamics; Performance Measures; Lateral Stability Control; Heavy Trucks; Lateral Instability;

    Abstract : One of the hazardous motions of heavy trucks is lateral instability which can be defined as deviation from driver intended path due to skidding of the vehicle. Lateral instability is associated with 9% of heavy trucks involved in traffic accidents, which represents a considerable figure when translated to real accidents. READ MORE

  5. 23. Learning Decision Trees and Random Forests from Histogram Data : An application to component failure prediction for heavy duty trucks

    Author : Ram Bahadur Gurung; Henrik Boström; Tony Lindgren; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; histogram decision trees; histogram random forest; prognostics; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : A large volume of data has become commonplace in many domains these days. Machine learning algorithms can be trained to look for any useful hidden patterns in such data. Sometimes, these big data might need to be summarized to make them into a manageable size, for example by using histograms, for various reasons. READ MORE

  6. 24. Truck Steering System and Driver Interaction

    Author : Kristoffer K D Tagesson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steering system; active safety; driver behaviour; active steering; torque feedback; heavy trucks;

    Abstract : This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented.

  7. 25. 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
