The invention discloses a ground clearance self-adaptive adjusting system of an automobile and a control method. The system comprises an adjusting structure and a control system. The adjusting structure comprises a shock absorber, an electric reversing valve and an oil pump mechanism. The shock absorber comprises a shock absorption piston cylinder, a shock absorption piston and an elastic element.A first oil port, a second oil port, an upper oil outlet and a lower oil outlet are formed in the shock absorption piston cylinder; and the electric reversing valve comprises a valve body and an electric actuator. The control system comprises a main controller and an acceleration sensor installed on the shock absorption piston cylinder. The acceleration sensor is electrically connected with an input end of the main controller so that acceleration signals, collected by the acceleration sensor, of the shock absorption piston cylinder are converted into electric signals and then are output to the main controller, and the output end of the main controller is further electrically connected with the oil pump and the electric actuator. According to the scheme, a purpose of increasing or decreasing the ground clearance of the automobile according to needs is achieved.
