The invention provides a method and device for adjusting the lifting rigidity of a frame, and the method comprises the steps: determining the number of remaining required execution steps for lifting according to the expected lifting rigidity, the maximum allowable change capacity and the expected lifting execution rigidity of the frame which are executed at the last moment, and adjusting the lifting rigidity of the frame according to all the remaining required execution steps for lifting of all wheels. Determining a four-wheel synchronous residual reference step number; determining a lifting rigidity synchronous control coefficient according to the expected lifting rigidity and the expected lifting execution rigidity of the frame executed at the last moment; according to the lifting rigidity synchronous control coefficient, the four-wheel synchronous residual reference step number, the expected lifting rigidity of the frame executed at the previous moment and the expected lifting execution rigidity, the expected lifting rigidity of the frame executed at the current moment is determined; and when the expected lifting rigidity of the frame executed at the current moment is equal to the corresponding expected lifting execution rigidity, it is determined that adjustment of the four-wheel frame of the vehicle is completed. The purpose of controlling the adjusting process of each wheel is achieved, and the posture of the vehicle tends to be stable.
