Whole vehicle schematic diagram design method

The invention relates to a whole vehicle schematic diagram design method, which comprises the following steps of: collecting interface information of electric appliance parts, establishing a response system code, and establishing a principle connection logic under each system; building a loop configuration code which is generated based on the system code addition configuration code; and establishing a logical relationship definition configuration matching relationship of the loop configuration codes for the same loop by adopting a logical combination strategy of the loop configuration codes. According to the method, categories and performance attributes of all materials on the whole vehicle schematic diagram are endowed, evolution of the schematic diagram from a single connection diagram to a functional logic production diagram is achieved, and the problems that the efficiency is low and the error rate is high due to the fact that configuration change is achieved by relying on loop connection relation adjustm
