The design of the automotive wiring harness system is a very complicated project, especially the current loop problem of the line. Under certain specific environmental conditions, the rational design of the circuit is the core of the electrical system. In general, the circuit system of a car is connected in parallel among different electronic devices. To test its circuit, it is necessary to change the connection mode of the circuit and simulate the possible situations in various situations, so as to ensure the normal operation of the wiring harness system.
With the rapid development of the automobile industry and the electronic technology industry, the use of electronic technology in automobiles has become more and more common, and users’ requirements for all aspects of automobiles have been continuously improved. In addition to its own functionality, many entertainment and safety measures have been added. However, car body space is limited. Therefore, the design of automotive wiring harness is very important. The improvement of the reliability of the automotive wiring harness design is a cumbersome industrial test process, and it is necessary to have all-round control over all aspects of the automotive wiring harness system design.
