1. Improving emergency braking performance of heavy vehicles
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.

2. Safety for Children in Cars – Focus on Three Point Seatbelts in Emergency Events
Sammanfattning : Child safety in vehicles has improved over time. One of the main factors is due to the increased restraint use by children. Nevertheless, studies show that although children are restrained, injuries still occur indicating that restraint systems have the potential for further improvement. LÄS MER
3. Towards Crash-Free Driving: Opportunities and Limitations of Automated Emergency Braking in Intersections
Sammanfattning : Intersections are a global traffic safety concern. In the Unites States, about half of the fatal road traffic accidents take place at intersections or were related to them. In the European Union, about one fifth of the road traffic fatalities occur at intersections. LÄS MER
4. Volunteer Muscle Activity in Dynamic Events. Input Data for Human Body Models
Sammanfattning : Human body models (HBMs) are virtual human surrogates used to predict kinematic and injury responses during motor vehicle crashes. In recent years, active musculature has been incorporated into HBMs for enhanced biofidelity in simulated emergency scenarios, in particular low-severity crashes and pre-crash situations, where occupant responses are influenced by muscle tension.

5. On Transient Communication Outages among Collaborating Connected and Automated Vehicles
Sammanfattning : Recent advances in wireless technology facilitating Vehicle-to-Vehicle (V2V) communication have paved the way towards connected and more cooperative Intelligent Transportation Systems (ITSs), enhancing road safety and sustainability. Connected and Automated Vehicles (CAVs) can exchange information with one another and their surrounding infrastructure, thereby enabling cooperative automated maneuvering such as vehicle platooning.
