1. 11. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles

   Författare :Erik Nordlund; Chandur Sadarangani; Hans Kahlen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electrical Machines; Hybrid Vehicles; Elektroteknik; Electrical engineering; Elektroteknik;

   Sammanfattning : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. LÄS MER

7. 15. 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.
