Simulation modeling method of whole vehicle circuit system

The invention aims to provide a modeling method for simulation of a whole vehicle circuit system, which can reduce repeated modeling of a model. The embodiment of the invention provides a simulation modeling method for a whole vehicle circuit system. The simulation modeling method comprises the following steps: s1, collecting information of electrical parts needing to be modeled of the whole vehicle circuit system; s2, classifying the collected electric device information according to preset classification information; s3, modeling is carried out on each type of electric devices after category division, specifically comprising that a physical layer is established firstly, then et an attribute layer is established, and finally an interaction layer is established, wherein physical architecture information of the electric device is recorded in the physical layer, the electrical attribute information of the electrical device is recorded in the attribute layer, and the electrical attribute information in the attri
