Wire harness occupies a large proportion in electromechanical products, such as widely used in aviation, aerospace, automobile, ship, household appliances and other fields. The main function of wire harness is to reliably transmit communication signals and ensure normal communication between electrical equipment. Its importance is equivalent to that of human nerves; The main function of pipeline is to stably and reliably transmit working media such as gas, liquid and electricity, so as to ensure that the product can complete its function safely and reliably. Its importance is equivalent to that of human blood vessels.

At present, the main functions that have been realized are: Harness modeling, vehicle harness design in virtual environment, establishing the initial model of harness in many ways; Assembly process simulation: realize the assembly process simulation of wire harness through the overall or local manipulation of the model and the dynamic modification of the model structure, ensure the authenticity of the assembly planning process through the real-time collision and interference detection algorithm, and ensure the authenticity of the appearance of the model through the curve fairing of the line and pipeline model; The assembly process information management forms the main content of the harness assembly process through the record of the assembly planning process, and forms documents such as three-dimensional design model, two-dimensional flattening drawing of harness and pipe flange, various reports and lists through the post-processing of the assembly planning results.

After the layout is completed, it will participate in the assembly process planning of the whole product as the structural part of automobile harness design, so as to obtain the information such as assembly sequence and assembly path of pipeline. The assembly process planning process is also the process of assembly analysis of pipeline parts. In the post-processing stage of planning results, after completing the assembly process planning of harness and pipeline, the assembly planner starts the result data post-processing module to count, process and output the assembly process planning results of harness, pipeline layout design and assembly process planning results, and can output three-dimensional design model, two-dimensional engineering drawing, raw material list, auxiliary material list, assembly process animation and initial assembly process documents. In the process data site browsing stage, the harness and pipeline manufacturer downloads the relevant design information of the harness from the data server, and makes the harness and pipeline based on it; The on-site assembly workers download the assembly process documents and assembly animation files stored on the data server locally through the client, and better understand the assembly process of the harness by viewing the process documents and assembly animation, so as to improve the standardization and reliability of harness assembly in complex products.

In order to improve the purpose of independent development and production of control automotive electronic products, we should strengthen policy support for the independent development of automotive electronic industry, encourage automotive harness design to develop new technologies and products, and guide more enterprises to enter the field of automotive electronics; Various ways to improve the independent innovation ability of automotive electronics enterprises; Deal with the relationship between digestion and absorption and independent innovation, actively seek ways to obtain technology spillover, improve the desire of enterprises to realize independent innovation, pay attention to establishing brands, and explore effective ways to combine industry, University and research in the field of automotive electronics.

Facing the opportunity, most experts believe that trucks, buses and medium and low-grade cars with independent intellectual property rights should first become a breakthrough in the development of control automotive electronic products in China.
