This paper investigates the dynamic time-event hybrid triggered reliable fuzzy controller design problem for vehicle nonlinear active suspensions subject to actuator deception attacks. First, an interval type-2 fuzzy model is employed for the concerned nonlinear active suspension system. Second, a dynamic time-event hybrid triggered scheme is proposed for signal transmission and communication, in which a Bernoulli distribution function is used for the dynamic switching between the time-triggered mode and the event-triggered mode. Third, considering that deception attacks may occur in the transmission network and change the actuator output, a random nonlinear function is introduced to represent the practical deception attacks. Moreover, a dynamic event-triggered reliable fuzzy controller design method is proposed for the closed-loop suspension control system to counter the negative impact resulted from deception attacks and further save network resources. Finally, experimental tests on a suspension test rig are provided to illustrate the superiority of the proposed method in comparison with current works.
