The invention discloses an automobile active-disturbance-rejection suspension system. The automobile active-disturbance-rejection suspension system comprises a spring upper support, a spring lower support and a wheel, and further comprises a linear motor, a spring element, a sensor and a controller, wherein the wheel is in rigid connection with the spring lower support, the linear motor is connected between the spring upper support and the spring lower support and used for adjusting the distance between the spring upper support and the spring lower support, the spring element is parallel to the linear motor and used for connecting the spring upper support with the spring lower support, the sensor is arranged below the spring upper support and used for detecting the distance between the spring upper support and the spring lower support, and the controller is used for receiving distance signals sent by the sensor and sending voltage signals to the linear motor. In a control method, the change of the distance value is estimated in advance, and then the voltage signal value is outputted so that the linear motor can be controlled to move; thus, the control and energy conservation effects of the method are remarkable. Through the method, the longitudinal acceleration of an automobile body of an automobile passing on a bumpy road can be effectively lowered, and then the ride comfort of the automobile is greatly improved.
