The invention discloses a cooperative control system and method for a damping-adjustable and vehicle body height-adjustable interconnection air suspension. The cooperative control system comprises a sensor module, a road unevenness recognition module, a driver instruction collection module, a coordination controller, an interconnection state controller, an interconnection state control execution mechanism, a damping controller, a damping control execution mechanism, a vehicle body height controller and a vehicle body height control execution mechanism. First, an interconnection state control strategy, a vehicle body height control strategy and a damping control strategy are made; then, the coordination controller is built, the working sequence of the controllers is determined according to current driving conditions, specific control sentences are corrected, vehicle body height control is corrected according to the interconnection state and the damping coefficient, and interconnection state control and damping control are corrected according to correction coefficients provided by the coordination controller. By means of the cooperative control system and method, an interconnection state control system, a vehicle body height control system and a damping control system can be effectively coordinated, and therefore the overall performance of the damping-adjustable and vehicle body height-adjustable interconnection air suspension can be obviously improved.
