2. 1. Nonlinear Model-based Control of Automotive Powertrains

   Author : Jonas Fredriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stability; diesel engine control; nonlinear control; gearshifting; air-to-fuel ratio control; drive- line oscillations; backstepping; powertrain modeling; powertrain control;

   Abstract : In recent years the focus of powertrain control has shifted perspective from control of the individual powertrain components to control of the complete powertrain, so-called integrated powertrain control. The idea presented in this thesis is to view the powertrain as one single control object and to used the engine as a torque actuator to the rest of the driveline. READ MORE

4. 2. Topics in Modeling, Control, and Implementation in Automotive Systems

   Author : Magnus Gäfvert; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; robotteknik; Automatiska system; control engineering;

   Abstract : This thesis treats different aspects of automotive control-systems and consists of four papers covering different areas in this large field. The first paper presents a 9-degrees-of-freedom dynamic model of a tractor-semitrailer vehicle, aimed at simulation and evaluation of active chassis-systems for stability enhancements. READ MORE

5. 3. Particle Filtering and Optimal Control for Vehicles and Robots

   Author : Karl Berntorp; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; particle filtering; optimal control; automotive systems; out-of-sequence measurement; autonomy; model predictive control; sensor fusion; wheel slip; dynamic optimization;

   Abstract : This thesis covers areas within estimation and optimal control of vehicles, in particular four-wheeled vehicles. One topic is how to handle delayed and out-of-sequence measurements (OOSMs) in tracking systems. READ MORE

6. 4. Automotive Electromagnetic Compatibility - Prediction and Analysis of Parasitic Components in Conductor Layouts

   Author : Sabine Alexandersson; Industriell elektroteknik och automation; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Parasitic components; Electromagnetic Compatibility; Crosstalk; Electromagnetic simulations;

   Abstract : The electronics in the automotive industry is facing a new era where safety critical functions are electrified, as for example drive-by-wire technology. At the same time as the number of electrical loads in the vehicles is increasing, the time to market is decreasing. READ MORE

7. 5. Deactivation mechanisms influencing the performance and durability of exhaust aftertreatment systems

   Author : Jesus De Abreu Goes; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal degradation; Gasoline particulate filters; Lean NOx traps; Sulfur poisoning.;

   Abstract : As countermeasure to air pollution and global warming, more stringent environmental policy measures will probably come into force with the future emission standards, which will require important developments for gasoline and diesel vehicles to meet the emerging criteria. Efficient catalytic formulations and advanced strategies for exhaust aftertreatment systems will be therefore demanded to provide both high catalytic activity and stability, minimizing the environmental impact by automobiles.
