1. 1. Optimal Speed and Powertrain Control of a Heavy-Duty Vehicle in Urban Driving

   Författare :Manne Held; Jonas Mårtensson; Jonas Fredriksson; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous vehicles; model predictive control; optimal control; heavy-duty vehicles; trucks; powertrain control; fuel; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : A major challenge in the transportation industry is how to reduce the emissions of greenhouse gases. One way of achieving this in vehicles is to drive more fuel-efficiently. LÄS MER

3. 2. Geometric analysis of stochastic model errors in system identification

   Författare :Jonas Mårtensson; Håkan Hjalmarsson; Michel Gevers; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic Control; Automatic control; Reglerteknik;

   Sammanfattning : Models of dynamical systems are important in many disciplines of science, ranging from physics and traditional mechanical and electrical engineering to life sciences, computer science and economics. Engineers, for example, use models for development, analysis and control of complex technical systems. LÄS MER

4. 3. Autonomous Avoidance Maneuvers for Vehicles using Optimization

   Författare :Pavel Anistratov; Lars Nielsen; Björn Olofsson; Jan Åslund; Jonas Mårtensson; Linköpings universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : To allow future autonomous passenger vehicles to be used in the same driving situations and conditions as ordinary vehicles are used by human drivers today, the control systems must be able to perform automated emergency maneuvers. In such maneuvers, vehicle dynamics, tire–road interaction, and limits on what the vehicle is capable of performing are key factors to consider. LÄS MER

5. 4. Safe Intersection and Merging Coordination of Connected and Automated Vehicles

   Författare :Xiao Chen; Jonas Mårtensson; Björn Olofsson; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Connected and automated vehicles (CAVs) are a transformative technology that promises to bring innovative solutions to transportation systems. One of their significant advantages is the elimination of human factors, which makes them capable of resolving the congestion problem prevalent in areas such as ramp merging points and road intersections.

7. 5. Modeling, Control and Optimization of theTransient Torque Response in DownsizedTurbocharged Spark Ignited Engines

   Författare :Oscar Flärdh; Håkan Hjalmarsson; Jonas Mårtensson; Per Tunestål; KTH; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engine modeling; Engine control; Transient torque response; Downsizing; Transient optimization;

   Sammanfattning : Increasing demands for lower carbon dioxide emissions and fuel consumption drive technological developments for car manufacturers. One trend that has shown success for reducing fuel consumption in spark ignited engines is downsizing, where the engine size is reduced to save fuel and a turbocharger is added to maintain the power output.
