The invention provides a transverse and longitudinal cooperative control method for self-adaptive speed regulation of an automatic driving vehicle. The method comprises the following steps: establishing a vehicle model and a tire model; according to the real-time position of the vehicle and global road information, carrying out real-time prediction and speed tracking on the longitudinal reference speed of the vehicle; and transverse and longitudinal cooperative control is carried out on the autonomous vehicle. According to the method, the longitudinal speed is adjusted through the path tracking error and the road curvature according to the vehicle state parameters and the predicted path information of different road surfaces, so that the real-time high-speed curve path tracking problem is solved.
