In order to reduce R&D costs and shorten the development cycle, the platform-based development strategy has become one of the important strategic measures of major OEMs in recent years, and models derived from various platforms have been continuously launched on the market. In order to further improve the generalization rate and reuse rate of components, the platform-based and modular development strategy of components has been widely used in the R&D and production of body-in-white, chassis, and powertrain-related components. As the neural network of the vehicle electrical system, the wiring harness system has always been in a subordinate position in the development of the matching system, adapting to the layout of other systems, matching the definition of the electrical end interface, and responding to the definition of the vehicle configuration, which ultimately leads to the fragmentation of the wiring harness system and low general rate. . There are three main deficiencies in the existing wiring harness system development model: ● The design verification cycle is long and changes are frequent. In the engineering design stage, it is necessary to continuously match the electrical appliances for layout. In the trial production stage, there are many problems, which need to be continuously adjusted, improved and verified, and the development node has been continuously delayed. ● There are many types of raw materials, long procurement cycle, and serious backlog of materials. Most of the purchased parts have a minimum order quantity and a procurement cycle of more than 60 days, which leads to the difficulty of arrival of the wiring harness in the trial production and verification stage. ● The generalization rate and reuse rate are low. The wiring harness assembly between different models is rarely universal, and the reuse rate of raw materials is low.
