Observer-Based Secure Control for Vehicular Platooning Under DoS Attacks

Abstract

This paper investigates an observer-based secure control problem for platooning of connected vehicles in the presence of Denial-of-Service (DoS) attacks. DoS attacks usually prevent the vehicle-to-vehicle data packets transmission which will lead to performance degradation of platooning system or vehicle collision. To deal with DoS attacks, we consider an observer-based mechanism to estimate the state of vehicles based on available sensor measurements which significantly improves the resilience and tolerance of platooning system during the attack interval. Then, we provide the optimization framework to maximize the duration of the DoS attack such that the platooning system can tolerate safe operation without performance degradation. The simulation results verify the effectiveness of the proposed method.
