Method for correcting whole vehicle posture of automobile multi-body dynamic model

The invention provides a method for correcting the whole vehicle posture of an automobile multi-body dynamic model, and belongs to the technical field of automobile simulation. According to the parameters of the target vehicle, the whole vehicle mass and the mass center coordinate of the vehicle multi-body dynamic model are preliminarily set, so that the axle load distribution of the virtual sample vehicle is consistent with that of the real vehicle; the ground clearance of specific points are respectively measuring on the target vehicle and the vehicle multi-body dynamic model to obtain a whole vehicle attitude parameter group respectively representing the target vehicle and the vehicle multi-body dynamic model; and an error absolute value of the two terrain clearances of the corresponding positions in the automobile multi-body dynamic model and the target vehicle whole-vehicle attitude parameter set is solved, the error absolute value is compared with a preset error threshold value for judgment, and if nece
