Disclosed is a method for improving the steering control precision of a driving front wheel under limited conditions. The method is characterized in that a reference model, a tire lateral force and cornering stiffness processor, an MPC and an automobile model are involved. The reference model is used for determining the expected yaw velocity and centroid side slip angle of an automobile; the tirelateral force and cornering stiffness processor is used for determining the side slip angle, lateral force and cornering stiffness of a tire; the automobile model is used for outputting actual motionstate information of the automobile, and the information comprises the longitudinal velocity, yaw velocity, centroid slip angle and road adhesion coefficient of the automobile; the MPC combines the expected yaw velocity and centroid slip angle of the automobile and the actual motion state information of the automobile to optimally calculate the front-wheel additional rotation angle of the automobile, superimposes the front-wheel additional rotation angle with a front-wheel rotation angle generated according to steering input of a driver and outputs a superimposition result to the automobile model to achieve stability control under the extreme conditions.
