1. On the interaction between driver assistance systems and drivers in situations of system failure
Sammanfattning : The level of automation is increasing in road vehicles as driver assistance systems take control of both speed and steering. Benefits of this development are expected in the form of improved safety, driver comfort, traffic efficiency, etc. LÄS MER
2. Safe Transitions to Manual Driving From Faulty Automated Driving System
Sammanfattning : This thesis presents a method to assess the safety of transitions from automated to manual driving when vehicle automation fails. The method is based on contributions to the understanding of human driving behavior, also presented in this thesis. LÄS MER
3. Modelling of cyclic and viscous behaviour of pearlitic steels. Application to tread braked railway wheels
Sammanfattning : Railway wheel and rail materials are subjected to very high stresses and, in some cases, also elevated temperatures. The rolling contact loading results in a multiaxial stress state with a combination of compression and shear. LÄS MER
4. When Driving Automation Fails. Drivers' Experiences and Interactions
Sammanfattning : Drivers’ interactions with automation based on experiences from real driving, and results from driving simulators were under investigation in this thesis. The thesis had a mixed methods research approach and was exploratory. Special attention has been given to driver behavior on exposure to unexpected automation failures. LÄS MER
5. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences
Sammanfattning : This thesis aims at systematically studying the possibilities of minimising devastatingconsequences of high-speed derailments by appropriate measures and features in thetrain design, including the running gear. The course of events immediately afterderailments is studied with respect to whether the train stays upright and close to thetrack centre line or deviates laterally with probably serious consequences.
