To reduce the communication burden between the controller and the actuator, this paper proposes an adaptive event-triggered control method for nonlinear vehicle active suspension systems with state constraints. Without determining a priori knowledge of the control direction, the presented approach can be implemented based on the constrained adaptive technique for simultaneously addressing the physical state limitations in the presence of parametric uncertainties and compensating the measurement error caused by the event triggering mechanism. A Lyapunov stability proof guarantees that the closed-loop suspension system is stable, and the suspension movement limitation is not violated. A designed example is given to illustrate the effectiveness of the presented controller for improving the vehicle ride performance.
