1 Introduction

As a connection carrier of the automotive electrical function, the wire beam product realizes the circuit connection between the electrical components. The starting point and end point of each circuit connection constitute the circuit in the wiring beam product. It can be said that the wire beam circuit is the core of the wiring beam product. The quality of the circuit design of the wire beam product directly determines the safety and reliability of the vehicle beam. With the improvement of vehicle electrification, the data of electrical components increases, the signal interaction between electrical appliances is getting closer and closer, and the number of car line beam circuits has also increased sharply. The line data of the general models has reached nearly 1,000 (Figure 1) Essence

How to optimize so many circuits is a problem facing the design of the car beam design.

The existing car beam design technical data mainly provides design guidance for the selection of online beam materials and manufacturing processing links, but lacks system analysis of the planning and design concept of the wire beam circuit. This article is from the aspects of cost and performance. The relevant focus of the design has explained it and provided a specific control path, which has a certain guiding effect on the design of the line beam circuit.

2 Cost -based circuit design method

The wire beam circuit accounts for about 90%of the cost of the wire beam material. Including the wires and connecting plug -ins, to control the design cost of the wiring beam, the design must be optimized from the wire beam design. For the use of wires, how to use the minimum wire length to achieve the circuit connection function is the first problem that the circuit design must be considered. This involves the design elements of the two aspects: the location of the electrical parts and the selection of the wire beam layout path. These two elements are independent and related, which has a significant impact on the use of wire length.

First of all, the connection method of the circuit is determined based on the principle of parts and components, and then determines the initial location of each component layout in the entire vehicle environment. The parts of the parts that are as many as possible are the prototype of the vehicle electrical topology.
