1. 1. A Holistic Safety Benefit Assessment Framework for Heavy Goods Vehicles

   Författare :Ron Schindler; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy goods vehicle; Bayesian methods; Safety benefit assessment; crash data analysis; driver behaviour modelling;

   Sammanfattning : In 2019, more than one million crashes occurred on European roads, resulting in almost 23,000 traffic fatalities. Although heavy goods vehicles (HGVs) were only involved in 4.4% of these crashes, their proportion in crashes with fatal outcomes was almost three times larger. LÄS MER

3. 2. On Traffic Situation Predictions for Automated Driving of Long Vehicle Combinations

   Författare :Peter Nilsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; braking; steering; heavy trucks; automated driving; long vehicle combination; active safety; vehicle dynamics; prediction; driver behaviour;

   Sammanfattning : The introduction of longer vehicle combinations for road transports than are currently allowed is an important viable option for achieving the environmental goals on transported goods in Sweden and Europe by the year 2030. This thesis addresses how driver assistance functionality for high-speed manoeuvring can be designed and realized for prospective long vehicle combinations. LÄS MER

5. 4. Improving emergency braking performance of heavy vehicles

   Författare :Leon Henderson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heavy vehicles; pneumatic brake actuator; ABS; pneumatic braking system; Slip control braking; HGV; vehicle testing; tyre dynamics;

   Sammanfattning : Previous studies by the Cambridge Vehicle Dynamics Consortium (CVDC) have suggested that, by improving the control bandwidth of conventional Heavy Goods Vehicle(HGV) brake actuators and using a ‘slip control’ braking strategy, HGV stopping distances could be reduced by up to 30% over existing systems. The work covered in this thesis looks to: validate the CVDC’s previous braking performance predictions through Hardware-in-the-Loop (HiL) simulation, investigate how in-plane tyre dynamics may influence such a system’s performance, develop and build a next generation high-bandwidth braking system for vehicle implementation and carry out comparative back-to-back vehicle tests between the new system and commercially available HGV ABS.

7. 5. Heavy Vehicle Maintenance in an Industrial Network Perspective: Implications of Embeddedness and Interdependencies

   Författare :Klas Hedvall; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Business Networks; Transport Solutions; Trucks; Activities; Transport Service Triad; Road Transports; ARA Model; Vehicle Maintenance; Interdependencies; Maintenance; Embeddedness;

   Sammanfattning : Road transport solutions are often complex and involve numerous stakeholders. To secure that goods arrive in a timely and efficient manner, companies must cooperate and interact to define, implement and operate the transport solutions required. LÄS MER
