2. 1. Troubleshooting Trucks : Automated Planning and Diagnosis

   Author : Håkan Warnquist; Patrick Doherty; Jonas Kvarnström; Louise Travé-Massuyès; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated planning; diagnosis; troubleshooting; automotive systems; Bayesian networks; Markov decision-processes;

   Abstract : This thesis considers computer-assisted troubleshooting of heavy vehicles such as trucks and buses. In this setting, the person that is troubleshooting a vehicle problem is assisted by a computer that is capable of listing possible faults that can explain the problem and gives recommendations of which actions to take in order to solve the problem such that the expected cost of restoring the vehicle is low.

4. 2. Driver-centred Motion Control of Heavy Trucks

   Author : Kristoffer K D Tagesson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver behaviour; active safety; torque feedback; heavy trucks; motion coordination; steering by braking; oncoming collision; electronic stability control; active steering;

   Abstract : Traffic accidents constitute one of the leading global causes of death. Deadly traffic accidents occur, even in countries that have implemented far-reaching countermeasures, at a rate that cannot be tolerated. Improved safety of heavy trucks is an important remedy, as these vehicles are involved in a large part of all fatal accidents. READ MORE

5. 3. Active Flow Control for Aircrafts and Heavy Vehicles

   Author : Mohammad El-Alti; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trucks; Drag reduction; Bluff-body; Large-eddy Simulation; Wake; Tilt-rotor wing; optimization; Aircrafts; Heavy vehicles; Active and Passive Flow Control; Response surface methodology; Synthetic-jet Actuator;

   Abstract : Bluff-body flows are dominated by large dissipative vortex-shedding wakes with low mean pressure compared to the high pressure on their frontal area. This induced pressure difference is the major contribution to the total aerodynamic drag. READ MORE

6. 4. Active Flow Control for Drag Reduction of Heavy Vehicles

   Author : Mohammad El-Alti; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active and Passive Flow Control; Tilt-rotor wing; Large-eddySimulation; Heavy vehicles; optimization; Full-scale road test; Trucks; Bluff-body; Wake; Drag reduction; Aircrafts; Response surface methodology; Synthetic-jet Actuator;

   Abstract : This thesis considers the aerodynamics of trucks. The work focuses on the aerodynamic drag caused by the wake. Bluff-body flows are dominated by large dissipative vortex-shedding wakes with a low mean pressure compared to the high pressure on their frontal area. READ MORE

7. 5. Predictive control for autonomous driving : With experimental evaluation on a heavy-duty construction truck

   Author : Pedro Lima; Bo Wahlberg; Jonas Mårtensson; Alberto Bemporad; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; automatic control; heavy-duty vehicles; mining; trucks; clothoids; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Autonomous vehicles is a rapidly expanding field, and promise to play an important role in society. In more isolated environments, vehicle automation can bring significant efficiency and production benefits and it eliminates repetitive jobs that can lead to inattention and accidents. READ MORE
