   Sammanfattning : This thesis analyses one of the less explored areas of Swedish politics: the political appointees in the ministerial staffs of the Swedish core executive. The study draws attention to the everyday life of the ministerial staff in order to give an idea of their function: What do the political appointees do? How is the work of the ministerial staffs organized? How is policy coordinated at the political level? The main empirical focus of this thesis is the 2002-2006 term of office. LÄS MER

3. 2. Truck Steering System and Driver Interaction

   Författare :Kristoffer K D Tagesson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steering system; active safety; driver behaviour; active steering; torque feedback; heavy trucks;

   Sammanfattning : This thesis presents a compilation of methods to consider when mapping steering functions and results as vehicle dimensions change. It is concluded that some final tuning inevitably will be required as major changes are performed. It is however possible to create qualified starting points using a set of simple rules as presented.

4. 3. Haptic Feedback Control Methods for Steering Systems

   Författare :Tushar Chugh; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; passivity and coupled stability; torque and position overlay; Haptic feedback; impedance and admittance control; system identification; steering system;

   Sammanfattning : Haptic feedback from the steering wheel is an important cue that defines the steering feel in the driver-vehicle interaction. The steering feedback response in an electric power assisted steering is primarily dependent on its control strategy. LÄS MER

5. 4. On Electrohydraulic Pressure Control for Power Steering Applications : Active Steering for Road Vehicles

   Författare :Alessandro Dell'Amico; Petter Krus; Massimo Milani; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : This thesis deals with the Electrohydraulic Power Steering system for road vehicles, using electronic pressure control valves. With an ever increasing demand for safer vehicles and fewer traffic accidents, steering-related active safety functions are becoming more common in modern vehicles. LÄS MER

7. 5. Driver Preferences of Steering Characteristics

   Författare :Markus Agebro; Annika Stensson; Lars Drugge; Christopher Patten; KTH; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Driver preferences; Steering characteristics; Steering systems; Driving simulator experiments; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

   Sammanfattning : The future of vehicle steering systems lies within by-wire technology. With by-wire technology mechanical or hydraulic systems are replaced by electronic systems. Removal of the steering column and possibly other linkage and gears yields vast potential of further improvement of performance, comfort and safety. LÄS MER
