1. 1. Passenger Car Wheel Aerodynamics

   Författare :Christoffer Landström; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; tyres; wind tunnel; Passenger car aerodynamics; ground simulation; wheel rotation; drag; wheels;

   Sammanfattning : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. LÄS MER

3. 2. How Does it Feel and How is it measured? Assessing Sitting Comfort and Postures of Rear-Seated Car Passengers in Stationary and Driven Scenarios Over Time

   Författare :Melina Makris; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sitting posture; sitting comfort; driving study; stationary study; seat belt fit; car comfort; car passenger; mixed-methods; seat belt comfort;

   Sammanfattning : This licentiate thesis presents the results of an empirical study focused on examining the comparative effectiveness of short stationary studies versus long driving studies in evaluating sitting postures, belt fit, and sitting comfort in cars. The study employed a mixed-methods approach, in which 19 participants experienced two different test scenarios in the rear seat of a car: a stationary scenario within an indoor garage and a driven scenario on a predefined route in regular traffic, each lasting 45 minutes.

5. 4. Evaluation of Adapted Passenger Cars for Drivers with Physical Disabilities

   Författare :Björn Peters; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Disabled person; Driver; Car; Adaptation; Equipment; Vehicle handling; Simulator; Adaptive cruise control; Driving aptitude; Thesis; 911 Road: Components of the vehicle; 911 Road: Components of the vehicle; 841 Road: Road user behaviour; 841 Road: Road user behaviour; 84 Road: Road users; 84 Road: Road users;

   Sammanfattning : Driving can provide independent and efficient mobility. However, according to the driving license directive (91/439/EEC) are persons with locomotor impairments are only allowed drive if their disabilities can be compensated. Compensation can be realised by vehicle adaptations. LÄS MER

7. 5. Minimize Vortex Drag of a Passenger Car

   Författare :Ture Jesper Marklund; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Boundary layer; Bluff bodies; Vehicle aerodynamics; Wake flow; CFD;

   Sammanfattning : The aerodynamic drag force is the single biggest resistance force for a passenger car toovercome at highway speeds. Since all driving resistance forces can be directly linked tofuel consumption this has become a significant priority in recent years. LÄS MER
