The invention provides an automotive active suspension control method with a dead-zone executer, which relates to automotive active suspension control methods. The invention is the automotive active suspension control method with the dead-zone executer, which is to solve problems that the prior art cannot meet requirements of keeping comfort under uneven pavement conditions and the lowering of the actual performance is not taken into consideration in the controller designing process of the prior art. The method comprises the following steps of step 1, establishing a mathematical model of a dead zone of the executer in an active suspension system; step 2, establishing a 1/4 automotive active suspension module with a dead-zone characteristic executer; step 3, designing a dead-zone compensating controller by means of the 1/4 automotive active suspension module with the dead-zone characteristic executer; step 4, verifying a closed-loop system, in which the dead-zone compensating controller is introduced into the 1/4 automotive active suspension system, by using an Lyapunoy function; and the like. The automotive active suspension control method with the dead-zone executer, provided by the invention, is applied to the control field of automotive active suspensions.
