  1. 11. Automated Driving Maneuvers - Trajectory Planning via Convex Optimization in the Model Predictive Control Framework

    Författare :Julia Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimization; Model Predictive Control; Trajectory planning; Lane Change; Automated Driving; Autonomous Driving; Advanced Driver Assistance Systems;

    Sammanfattning : Highly automated vehicles have the potential to provide a variety of benefits e.g., decreasing traffic injuries and fatalities while offering people the freedom to choose how to spend their time in their vehicle without jeopardizing the safety of themselves or other traffic participants.

  3. 12. Coupled Simulations of Cooling and Engine Systems for Unsteady Analysis of the Benefits of Thermal Engine Encapsulation

    Författare :Blago Minovski; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Oil system; Cooling system; Drive cycle; CFD simulations; Fuel consumption; Engine encapsulation; 1D simulations;

    Sammanfattning : A well-designed engine encapsulation can extend engine cool-down time significantly - on the order of 500 - 700%. This is expected to have a sensitive influence on the fuel consumption due to the increased probability for high oil temperatures at the following engine start, reduced length of the initial warm-up period and consequently, reduced friction losses.

  4. 13. Falsification of Signal-Based Specifications for Cyber-Physical Systems

    Författare :Johan Lidén Eddeland; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-Based Verification; Testing; Falsification; Cyber-Physical Systems;

    Sammanfattning : In the development of software for modern Cyber-Physical Systems, testing is an integral part that is rightfully given a lot of attention. Testing is done on many different abstraction levels, and especially for large-scale industrial systems, it can be difficult to know when the testing should conclude and the software can be considered correct enough for making its way into production.

  5. 14. CFD modelling of axial fans for thermal management applications

    Författare :Randi Franzke; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRF; CFD; RBM; Axial Fan; Thermal Management;

    Sammanfattning : Reducing CO2 emissions is one of the key challenges in todays automotive industry. Different strategies to achieve this goal are, for example, to electrify the powertrain and to reduce the aerodynamic drag by reducing the amount of cooling air through the underhood. LÄS MER

  7. 15. On Falsification of Large-Scale Cyber-Physical Systems

    Författare :Johan Lidén Eddeland; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Test Coverage; Testing; Optimization; Simulation-Based Verification; Formal Requirements; Cyber-Physical Systems; Falsification;

    Sammanfattning : In the development of modern Cyber-Physical Systems, Model-Based Testing of the closed-loop system is an approach for finding potential faults and increasing quality of developed products. Testing is done on many different abstraction levels, and for large-scale industrial systems, there are several challenges. LÄS MER
