Abstract This paper investigates the problem of globally fixed‐time longitudinal cooperative control for intelligent connected vehicle platoons (ICVPs) subjected to denial‐of‐service (DoS) attacks. First, a novel distributed fixed‐time observer is designed to estimate the state information of the leading vehicle under DoS attacks. Subsequently, by leveraging the switching system framework and fixed‐time stability theory, we guarantee that the estimation error converges to zero within a fixed time. On this basis, a distributed fixed‐time controller based on integral sliding mode strategy is designed, which can stabilize the vehicle tracking error system within a fixed time and maintain a safe inter‐vehicle distance. Finally, the effectiveness of the proposed control method is verified through simulation and comparative experiments.
