1. 21. Reconfigurable Motion Control Systems for Over-Actuated Road Vehicles

   Författare :Leo Laine; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; over-actuated; road vehicle; reconfigurable; control allocation; hybrid electric vehicle; motion control system;

   Sammanfattning : Over-actuated systems, such as today's road vehicle configurations, have more motion actuators than controlled motions. For example, a passenger car has a combustion engine and four mechanical brakes, all of which can be used individually to correct any error in yaw rate when the vehicle becomes under- or oversteered.

3. 22. Electric Machine Control for Energy Efficient Electric Drive Systems

   Författare :Andreas Andersson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modulation techniques; permanent magnet synchronous machine PMSM ; Energy efficiency; inverter control.; noise assessment;

   Sammanfattning : Over the past decade, electric vehicles has increasingly become an area of attention for both academia and industry, much due to challenges such as emissions legislation and the environmental impact of the transportation sector. The absence of the broadband noise from the internal combustion engine brings new acoustic challenges for electric propulsion applications. LÄS MER

4. 23. Supervisory control for emission compliance of heavy-duty vehicles

   Författare :Mohammed Razaul Karim; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; supervisory control; Euro VI emission legislation; exhaust aftertreatment system; Pontryagin’s minimum principle; E-NMPC.; Diesel engines;

   Sammanfattning : Heavy freight trucks globally contribute to a significant proportion of transport-related air pollution. The dominant air pollutants from heavy freight trucks with diesel engine and exhaust aftertreatment system (EATS) are CO2, hydrocarbons (HC), CO, particulate matter (PM), NOX (NO and NO2), and NH3.

5. 24. Haptic Feedback Control Methods for Steering Systems

   Författare :Tushar Chugh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passivity and coupled stability; torque and position overlay; Haptic feedback; impedance and admittance control; system identification; steering system;

   Sammanfattning : Haptic feedback from the steering wheel is an important cue that defines the steering feel in the driver-vehicle interaction. The steering feedback response in an electric power assisted steering is primarily dependent on its control strategy. LÄS MER

7. 25. On Energy Management Strategies for Hybrid Electric Vehicles

   Författare :Lars Johannesson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid Electric Vehicle; Energy Management; Vehicle Telematics; Powertrain Control; Stochastic Dynamic Programming; Driver Model; Predictive Control; Hybrid Vehicle;

   Sammanfattning : Hybrid electric vehicles are characterized by the existence of an electric energy buffer in the powertrain. Compared to a conventional vehicle the existence of the buffer means an extra degree of freedom in the powertrain. LÄS MER
