The invention provides a method and device for determining the mass center of a whole vehicle. The method comprises the steps that the mass center height of a basic vehicle model, the height of the basic vehicle model, the height of a newly developed vehicle model, influence parameters of vehicle body configuration on the mass center height and influence parameters of a power assembly on the mass center height are obtained; calculating a correction coefficient according to the height of the basic vehicle model and the height of the newly developed vehicle model; correcting the height of the mass center of the basic vehicle model according to the correction coefficient, and calculating to obtain the corrected height of the mass center of the basic vehicle model; and according to the corrected height of the mass center of the basic vehicle model, the influence parameter of the vehicle body configuration on the mass center height and the influence parameter of the power assembly on the mass center height, calculating to obtain a first estimated mass center height of the newly developed vehicle model. The method and device for determining the mass center of the whole vehicle can quickly and accurately predict the height of the mass center of the whole vehicle at the initial development stage of a whole vehicle project.
