1. 11. Parallel design optimization of multi-trailer articulated heavy vehicles with active safety systems

   Författare :Manjurul Islam; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety systems; Active trailer steering; Multi-trailer articulated heavy vehicles; High performance computing; Design optimization;

   Sammanfattning : Multi-trailer articulated heavy vehicles (MTAHVs) exhibit unstable motion modes at high speeds, including jack-knifing, trailer swing, and roll-over. These unstable motion modes may lead to fatal accidents. On the other hand, these vehicle combinations have poor maneuverability at low speeds. LÄS MER

3. 12. Towards Driver Adaptive Active Safety Systems

   Författare :Malin Sundbom; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In recent years, active safety systems have become a standard accessory in new cars and trucks. This thesis addresses one of the major flaws of most such systems: they act the same independently of who is operating the vehicle. LÄS MER

4. 13. Computational Verification Methods for Automotive Safety Systems

   Författare :Jonas Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Active Safety; Automotive; Verification; Augmented Reality; Performance Evaluation; Decision Making; Semi-Autonomous Vehicles;

   Sammanfattning : This thesis considers computational methods for analysis and verification of the class of automotive safety systems which support the driver by monitoring the vehicle and its surroundings, identifying hazardous situations and actively intervening to prevent or mitigate consequences of accidents. Verification of these systems poses a major challenge, since system decisions are based on remote sensing of the surrounding environment and incorrect decisions are only rarely accepted by the driver.

5. 14. On Cyber-Security for In-Vehicle Software

   Författare :Aljoscha Lautenbach; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Security; Memory Protection; Automotive Security; Memory Exploitation; In-Vehicle Network; Risk Assessment; CAN authentication; Secure Software Development;

   Sammanfattning : We live in a highly connected world, which brings many opportunities, but which also makes us vulnerable to attacks. Security in regular IT systems, such as desktop and server systems, has decades of active research behind it, whereas security in the automotive domain is still a relatively new topic. LÄS MER

7. 15. On Active Suspension in Rail Vehicles

   Författare :Alireza Qazizadeh; Sebastian Stichel; Rickard Persson; T. X. Mei; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active suspension; ride comfort; wear; skyhook control; H_infinity control; two-axle rail vehicle; safety; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The topic of this PhD thesis is active suspension in rail vehicles whichis usually realized through sensors, controllers and actuation components.A well established example of an active suspension is the tiltingcontrol system used to tilt the carbody in curves to reduce centrifugalacceleration felt by passengers.
