  1. 1. Tracking and threat assessment for automotive collision avoidance

    Författare :Andreas Eidehall; Fredrik Gustafsson; Aris Polychronopoulos; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; collision avoidance; lane guidance; state estimation; target trackin; Kalman filter; centralized filtering; threa; Automatic control; Reglerteknik;

    Sammanfattning : This thesis is concerned with automotive active safety, and a central theme is a new safety function called Emergency Lane Assist (ELA). Automotive safety is often categorised into passive and active safety, where passive safety is concerned with reducing the effects of accidents and active safety aims at avoiding them. LÄS MER

  3. 2. Developing Theoretical and Empirical Definitions of Safety Problems in Driving Suitable for Active Safety Function Evaluation

    Författare :Mikael Ljung Aust; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; avoidance; driver behaviour; pre-crash scenarios; crash causation; adaptation; motivation; conceptual framework; active safety functions;

    Sammanfattning : In passive safety, the requirement specifications used for evaluation of protective functions are both standardised and specified at a high level of detail regarding evaluation scenario definition, performance metrics and pass/fail criteria. For active safety, while several propositions for evaluation scenarios have been made, neither these, nor performance metrics and pass/fail criteria have yet reached a similar level of detail and standardisation.

  4. 3. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Författare :Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Sammanfattning : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. LÄS MER

  5. 4. Safety-oriented communication in mobile networks for vehicles

    Författare :Ioan Chisalita; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vehicular communication; active safety systems; collision warning and avoidance; safety-related information; Computer science; Datavetenskap;

    Sammanfattning : Accident statistics indicate that every year a large number of casualties and extensive property losses are recorded due to traffic accidents. Consequently, efforts are directed towards developing passive and active safety systems that help reducing the severity of crashes or prevent vehicles to collide with each other. LÄS MER

  7. 5. 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
