<p>Partial component consensus describes a novel weak collective dynamics in nature and intelligent transportation systems, indicating that several crucial components of the agents attain a steady state. This paper devotes to the partial component consensus matter for multi-connected automatic vehicle systems (MCAVS) formation via event-driven control schemes on the uncertain network scenario. To facilitate valid information interaction and minify communication expenses for controlled systems, the communication architecture between vehicles is illustrated by event-based robust control schemes when controlled systems subjected to aperiodic denial-of-service (DoS) attacks. Specifically, the event-based triggering function solely rests on several necessary component states of vehicles, and the interval duration of any two consecutive triggering instants encompass a minimum positive value, therefore Zeno phenomenon can be ruled out. What’s more, a self-triggered strategy is further presented to prevent sequential event detections by calculating the forthcoming triggering instant from the current triggering instant state. Based on partial variables stability theory, some sufficient conditions are established to realize component consensus formation control for MCAVS, which is correlated with the frequency and length parameters of DoS attacks. Finally, a numerical example is provided to clarify the rightness and benefits for the presented scheme.</p>
