The invention discloses an active suspension control strategy based on a fuzzy theory, and the strategy comprises the steps: building a road surface excitation model based on a white noise method, building a road surface time domain response model which reflects the unevenness of a road surface, building a suspension model of seven degrees of freedom of a whole vehicle, and employing the fuzzy theory according to a PID controller. An active suspension fuzzy control-PID controller is established, an actuator model of an active suspension system is established, and the active suspension control strategy based on the fuzzy theory provides an accurate model actuator for the control strategy. Off-line simulation can be carried out, and the influence of factors of other people in a real vehicle experiment is avoided.
