2. 1. Vehicle Conceptualisation, Compactness, and Subsystem Interaction : A network approach to design and analyse the complex interdependencies in vehicles

   Author : Sai Kausik Abburu; Carlos Casanueva; Ciarán J. O'Reilly; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Subsystem interaction; Interaction effects; Design Structure Matrix; Network theory; Cross-scalar design tool; Induction motor; Inverter.; Farkostteknik; Vehicle and Maritime Engineering;

   Abstract : The conventional approach to vehicle design is restrictive, limited, andbiased. This often leads to sub-optimal utilisation of vehicle capabilities and allocated resources and ultimately entails the repercussions of designing andlater on an using an inefficient vehicle. READ MORE

4. 2. Controlling over-actuated road vehicles during failure conditions

   Author : Daniel Wanner; Annika Stensson Trigell; Lars Drugge; Mats Jonasson; Jochen Rauh; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle dynamics; vehicle safety; driver-vehicle interaction; failure analysis; wheel hub motor failure; over-actuation; fault-tolerant control; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : The aim of electrification of chassis and driveline systems in road vehicles is to reduce the global emissions and their impact on the environment. The electrification of such systems in vehicles is enabling a whole new set of functionalities improving safety, handling and comfort for the user. READ MORE

5. 3. Reduction of Audible Noise of a Traction Motor at PWM Operation

   Author : Hanna Amlinger; Ines Lopez Arteaga; Siv Leth; Wolfgang Kropp; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electromagnetic noise; pulse width modulation PWM ; switching frequency; traction motor; Vehicle and Maritime Engineering; Farkostteknik;

   Abstract : A dominating source for the radiated acoustic noise from a train at low speeds is the traction motor. This noise originates from electromagnetic forces acting on the structure resulting in vibrations on the surface and thus radiated noise. It is often perceived as annoying due to its tonal nature.

6. 4. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

   Author : Anton Albinsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

   Abstract : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. READ MORE

7. 5. Reconfigurable Motion Control Systems for Over-Actuated Road Vehicles

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

   Abstract : 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.
