1. 6. On Generic Road Vehicle Motion Modelling and Control

   Författare :Johan Andreasson; Annika Stensson Trigell; Matt Best; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle engineering; Farkostteknik;

   Sammanfattning : With the increased amount of on-board electric power driven by the ongoing hybridization, new ways to realize vehicles are likely to occur. This thesis outlines a future direction of vehicle motion control based on the assumptions that: 1) future vehicle development will face an increased amount of available actuators for vehicle propulsion and control that will open up for an increased variety of possible configurations, 2) the onboard computational power will continue to increase and allow higher demands on active safety and drivability that will require a tighter interaction between sensors and actuators, 3) the trend towards more individualized vehicles on common platforms with shorter time-to-market require design approaches that allow engineering knowledge to be transferred conveniently from one generation to the next.

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

   Författare :Adithya Arikere; Chalmers tekniska högskola; []
   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

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

   Författare :Adithya Arikere; Chalmers tekniska högskola; []
   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

5. 9. Online State Estimation in Electrified Vehicles Linked to Vehicle Dynamics

   Författare :Anton Albinsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electric vehicles; state estimation; vehicle dynamics; parameter estimation; tyre-road friction estimation; active safety;

   Sammanfattning : Electric vehicles have the potential to significantly reduce energy consumption and emissions for personal and commercial road transport and number of electric vehicles is likely to increase in the future due to stricter emission legislations. In order to accelerate market penetration, the competiveness of electric vehicles should increase in comparison to conventional vehicles. LÄS MER

7. 10. Waste-Heat Recovery from Combustion Engines based on the Rankine Cycle

   Författare :Gunnar Latz; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rankine cycle; waste heat recovery; energy losses; energy efficiency; vehicle propulsion;

   Sammanfattning : The majority of the energy in the fuel burned by the combustion engines used in modern vehicles is lost in the form of waste heat and does not contribute to the propulsion of the vehicle. Three different technologies have been proposed for recovering some of this lost heat and thereby increasing the overall efficiency of combustion engines: the turbocompound, thermoelectric converters, and heat engines based on the Rankine cycle.
