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.

    本发明提供一种整车质心确定方法及装置,包括:获取基础车型质心高度、基础车型高度、新开发车型高度、车身配置对质心高度的影响参数、动力总成对质心高度的影响参数;根据所述基础车型高度、所述新开发车型高度计算获得修正系数;根据所述修正系数对所述基础车型质心高度进行修正,计算获得基础车型质心修正高度;根据所述基础车型质心修正高度、所述车身配置对质心高度的影响参数和动力总成对质心高度的影响参数,计算获得新开发车型第一预估质心高度。本发明的整车质心确定方法及装置能够在整车项目开发初期快速、准确预测整车质心高度。
