In recent years, virtual proving ground (VPG) technique has been widely used in vehicle multi-body dynamics analysis. This paper mainly focuses on the method to construct the digital roads incorporated in the virtual proving ground. At first, the Mobile Road Scanning System was introduced to acquire point clouds of the physical test roads of an actual proving ground located in southwest of China. Then, considering both road characteristics and development requirements, a CRG road surface model construction methodology was proposed. In the end, digital surface models of the physical test roads were constructed and coupled in full-vehicle simulations. As a result, the simulation based on the proposed method can predict the external loads of wheel parts under various loading cases, by comparing with load data acquired by experiments. In consequence, our research will assist in providing an efficient tool for the analysis of vehicle system/sub-system loads.
