  2. 1. Qualitative and Quantitative Assessment of Integration Testing for Model-Based Software in the Automotive Industry

    Author : Jan Schröder; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Industrial Case Studies; Software Quality; Validation; Software Metrics; Maintainability; Software Engineering; Empirical Research; Technical Debt;

    Abstract : Background: Integration testing of vehicle software in the automotive industry relies heavily on simulation models. As they replicate actual vehicle functions in the testing process, they increase in size and amount of interconnectivity as rapidly as the actual functions. Valid simulation models are a precondition for valid integration testing. READ MORE

  4. 2. Distributed vehicle testing : dynamic simulation for automotive winter testing

    Author : Mikael Nybacka; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funktionella produkter; Functional Product Development;

    Abstract : Today, rather than provide parts similar to their competitors and rely on one or two automakers, successful automotive component suppliers focus heavily on innovation and collaboration with several manufacturers in a global market. In this thesis, an as-is scenario for automotive winter testing is presented. READ MORE

  5. 3. Efficient Full-Scale CFD for Ship Hydrodynamics

    Author : Michal Orych; Chalmers tekniska högskola; []

  7. 5. Hydraulic Power Steering System Design in Road Vehicles : Analysis, Testing and Enhanced Functionality

    Author : Marcus Rösth; Jan-Ove Palmberg; Nick Vaughan; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic Power Steering; Active Safety; Comfort function; Shuttering; Linear modelling; Fluid mechanics; Strömningsmekanik;

    Abstract : Demands for including more functions such as haptic guiding in power steering systems in road vehicles have increased with requirements on new active safety and comfort systems. Active safety systems, which have been proven to have a positive effect on overall vehicle safety, refer to systems that give the driver assistance in more and less critical situations to avoid accidents.
