Complete vehicle wire harness arrangement method based on CHS topological structure

Abstract

The invention relates to a CHS topological structure-based finished automobile wire harness arrangement method. The method comprises the following steps of: drawing a finished automobile topological graph in a topological design module according to a finished automobile electrical schematic diagram and finished automobile wire harness three-dimensional data; performing association mapping on the whole vehicle topological graph and the whole vehicle electrical schematic diagram to generate wire loop information including a logic relation and physical wiring; length dimension information of each branch of the whole vehicle wire harness is set in the topological structure of the logic module Logic; calculating the lead length, weight and cost of the topology scheme through the embedded Plug of the comprehensive module; and comparing and analyzing the optimal schemes of the length, the weight and the cost of the lead under the plurality of topology schemes, and obtaining the optimal scheme. The method is based on a CHS wiring harness platform topological structure, is a mature and convenient topological structure, and can effectively achieve the optimal design of the wiring harness cost of the whole vehicle by optimizing the wiring harness arrangement method.

Description

technical field [0001] The invention relates to the technical field of vehicle electrical design, in particular to a method for arranging a vehicle wiring harness based on a CHS topology structure. Background technique [0002] With the further development of electronic and intelligent automotive electronics, there are more and more electrical equipment and electrical functions in automobiles. Each electrical function module of the vehicle needs to be connected by a wiring harness, so as to realize various functions of the vehicle's electrical appliances. The cost proportion of the vehicle wiring harness is increasing year by year in the total vehicle electrical development cost, and the quality of the vehicle wiring harness layout has always been an important factor affecting the cost of the vehicle wiring harness, and there is no mature and convenient topology structure. The cost-optimized design of the vehicle wiring harness can be achieved by optimizing the wiring harne...

The cost proportion of the vehicle wiring harness is increasing year by year in the total cost of vehicle electrical development, and the layout of the vehicle wiring harness has always been an important factor affecting the cost of the vehicle wiring harness, but there is no mature and convenient topology at present The cost-optimized design of the vehicle wiring harness can be realized by optimizing the wiring harness layout method

[0003] In addition, platform-based development of automotive electrical appliances has become a trend. Platform-based models have a lot of reference and use in the layout of vehicle wiring harness systems. At present, when designing models with the same platform, the layout of vehicle wiring harnesses does not fully consider the platform. change
