Abstract:Automated vehicles promote road safety, fuel efficiency, and reduced travel time by decreasing traffic
congestion and driver workload. In a vehicle platoon (grouping vehicles to increase road capacity by
managing distance between vehicles using electrical and mechanical coupling) of such automated
vehicles, as in automated highway systems (AHS), tracking of inter-vehicular spacing is one of the
significant factors under consideration. Because of close spacing, computer-controlled platoons with
inter-vehicular communication—the concept of adaptive cruise control (ACC)—become open to
cybersecurity attacks.
Cyber physical (CP) and cyber attacks on smart grid electrical systems have been a significant focus of
researchers. However, CP attacks on autonomous vehicle platoons have not been examined. This
research surveys a number of models of longitudinal vehicle motion and analysis of a special class of CP
attacks called false data injection (FDI) on vehicle platoons. In this kind of attack, the configuration of
any CP system is exploited to introduce arbitrary errors to gain control over the system. Here, an n-vehicle platoon is considered and a linearized vehicle model is used as a test-bed to study vehicle
dynamics and control, after false information is fed into the system.
