  1. 1. Estimation of torque in heavy duty vehicles with focus on sensor hysteresis

    Författare :Marcus Hedegärd; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hysteresis modelling; adaptive hysteresis compensation; hysteresis compensation; magnetoelastic torque sensor; Preisach model; generalized Prandtl-Ishlinskii model; cylinder pressure estimation; torque estimation;

    Sammanfattning : For diagnosis and feedback control of vehicle powertrains, it is highly desired to monitor the torques at different locations online. The most obvious way to do this is to measure cylinder pressures, from which cylinder individual delivered torques can be calculated, or to use torque sensors. LÄS MER

  3. 2. Torque based estimation of diesel engine combustion phasing

    Författare :Mikael Thor; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combustion modeling; Diesel engines; Crankshaft torque measurements; Combustion phasing control; Combustion phasing estimation;

    Sammanfattning : Demands on increased efficiency and reduced emission levels introduce new challenges for the design of modern diesel engines. In order to fulfill these demands, diesel engines of today are becoming more and more complex. This escalating complexity not only applies to the engine itself, but also to its control system.
