Abstract
This thesis aims to address question of safety and security in autonomous highway systems. Chains of multiple self-driving vehicles (platoons) give rise to inherent vulnerabilities to attacks resulting from their control algorithms. These weaknesses can possibly result in collisions or decreased traffic flow.
This work first provides an overview of these vulnerabilities analyzed from a control systems perspective. The capabilities and extent of damage that an attack can cause are analyzed. Then some possible mitigation strategies are presented that can defend against these attacks.
Simulation results are provided to support the effectiveness of these controllers and an experimental validation is performed. It is concluded that by appropriate controller design, the objectives of platooning in a system under attack can be recovered by using a control scheme designed to withstand attacks.
