On Control Strategy and Safety Verification of Automated Vehicles
- 2013

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Over the last few decades, congested traffic network have become a serious problem in many countries. Congestions result in time losses, increase of fuel consumption, increase of CO2 emissions and also raise the risk of accidents. While developing the road networks is not a feasible solution in many countries, intelligent transportation systems (ITS) may contribute to mitigate such problems. It is known that human errors or the delay in human’s reactions is the main cause of many of the problem in current transportation systems. Hence, cooperative driving or in particular vehicle platooning is an example of an ITS which exploits advanced technology like, on-board vehicle sensors, wireless communication and control engineering to improve the traffic situation. However, development of such complex system requires a reliable control algorithm which can guarantee passenger safety and comfort while satisfying certain specifications. This thesis deals with the development of a distributed control strategy for a vehicle platoon. The aim of the control strategy is to enable platooning with a short inter-vehicle distance while fulfilling the so called string stability criterion and maintaining the safety and comfort. The control design is divided into longitudinal and lateral control of vehicle. Simulation and experimental results indicate that string stability in longitudinal and lateral direction can be achieved using the proposed control strategy. Furthermore, a safety verification method based on reachability analysis technique and invariant set theory is proposed for safety analysis of such autonomous systems for a given cooperative controller. The safety verification method is extended to account for model uncertainty and measurement noises. The findings in this thesis are verified through simulations and field tests.

Bokkapitel (refereegranskat)abstract
- Modelling and simulation approaches are applied in a variety of scientific disciplines for analysing, planning, and optimising complex systems or phenomena. Simulation is not limited to applications related to computer science or information systems research [2] and has also become an accepted method, for example, in social sciences and medicine. But also for solving practical problems, e.g., in manufacturing, logistics, or engineering, the use of simulation is increasingly common. Due to its popularity and versatility, simulation is even referred to as a third pillar of science between theory and experiment [1].

Tidskriftsartikel (refereegranskat)abstract
- In 1899, the British colonialist Cecil Rhodes went to Berlin to negotiate about his fantastical ‘Cape-to-Cairo’ telegraph and railway scheme with his former nemesis, the German emperor Wilhelm II. Why did this initiative of Rhodes, who was held responsible for the disastrous Jameson Raid and no longer occupied any official position, receive so much coverage and legitimacy in the international press? Despite the vast scholarship on Rhodes, there is strikingly little analysis of these negotiations, considering that they were hailed as marking the rehabilitation of Rhodes and the troubled Anglo-German relationship, signalled that Germany would not support the Boers in their conflict with Britain, and led to Germany’s inclusion in the prestigious Rhodes Scholarships scheme. This article analyses the reporting of the negotiations and shows that Rhodes overshadowed other political figures in the competitive ‘attention economy’ of the emerging mass press. Building on the notion of ‘celebrity politics’, it argues that the press attention for him resulted from three interconnected logics: a political logic of agenda-setting and ideological loyalties, a journalistic logic in which scarce access to Rhodes fostered his mythologising, and a mass media logic that increasingly superseded ideological divides. This mass media logic dictated a focus on Rhodes’s personal narrative (infused with literary and colonial themes), personifying politics, and performing these politics in a novel business-like style. This press attention gained Rhodes informal power and shows how, by the end of the nineteenth century, successful politics required the new ability of political figures to attract and leverage media attention. Moreover, it constituted the precondition for the growing cult of Rhodes in the twentieth century, and the subsequent criticism of this cult and its representation of racism in recent times.
