1. 1. Muscle Responses of Car Occupants: Numerical Modeling and Volunteer Experiments under Pre-Crash Braking Conditions

   Författare :Jonas Östh; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedback postural control; autonomous braking; electromyography; active muscle; anticipatory postural control; seat belt pre-tension; driver braking; human body model; finite element; occupant kinematics;

   Sammanfattning : Over 30 000 fatalities related to the road transport system are reported anually in Europe. Of these fatalities, the largest share is car occupants, even though significant improvements in vehicle safety have been achieved by the implementation of in-crash restraints and pre-crash driver support systems.

3. 2. Look-ahead control for fuel-efficient and safe heavy-duty vehicle platooning

   Författare :Valerio Turri; Karl H. Johansson; Petros Ioannou; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; platoon; platooning; optimization; optimal control; model predictive control; automatic control; fuel efficiency; intelligent transport systems; automated driving; cooperative; dynamic programming; trucks; heavy-duty vehicles; safe platooning; fuel-efficient platooning; distributed model predictive control; MPC; vehicle-following; pulse and glide; Farkostteknik; Vehicle and Maritime Engineering;

   Sammanfattning : The operation of heavy-duty vehicles at small inter-vehicular distances, known as platoons, lowers the aerodynamic drag and, therefore, reduces fuel consumption and greenhouse gas emissions. Tests conducted on flat roads have shown the potential of platooning to reduce the fuel consumption of about 10%. LÄS MER

4. 3. A Methodology for the Design of Cost Effective Hybrid Vehicles

   Författare :Jonas Hellgren; Chalmers University of Technology; []
   Nyckelord :fuzzy logic; system engineering; model car; optimal design; evolutionary algorithms; hybrid electric vehicle; alternative powertrain; simulation; modeling; genetic algorithms; fuel cell vehicle; hybrid vehicle;

   Sammanfattning : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. LÄS MER

5. 4. Vehicle Dynamics Control for Active Safety Functions using Electrified Drivelines

   Författare :Adithya Arikere; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; driver assistance systems; intersection accidents; torque vectoring; optimal control; rear- end collisions; speed control; active safety; vehicle dynamics; electrified drivetrain; obstacle avoidance with oncoming traffic;

   Sammanfattning : Studies have shown that even considering pledges and commitments made by various governments and organisations, the growth in electrified vehicle sales is likely to be insufficient to reduce CO2 emissions for mitigating global warming. Some form of added incentive is needed that can help drive electrified vehicle sales in the open market. LÄS MER

7. 5. Vehicle Dynamic Opportunities in Electrified Vehicles for Active Safety Interventions

   Författare :Adithya Arikere; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rear-end collisions; active safety; vehicle dynamics; obstacle avoidance with oncoming traffic; speed control; electrified drivetrain; torque vectoring; driver assistance systems;

   Sammanfattning : Although the sales of electrified vehicles is growing, studies indicatethat the growth is inadequate to sufficiently reduce CO2 emissions andmitigate global warming. Some form of added incentive is needed to driveelectrified vehicle sales. LÄS MER
