Vehicle low-voltage wiring harness product design method

Abstract

The invention provides a vehicle low-voltage wiring harness product design method which comprises the following steps: determining the function configuration of a whole vehicle electrical system according to the function demand input of the electrical system; generating an electrical schematic diagram; considering electromagnetic compatibility requirement input to determine a wiring harness three-dimensional arrangement scheme; generating a wire harness two-dimensional drawing; performing small-batch wire harness production and electrical detection; performing trial assembling of small-batch wire harnesses on a production trial assembly vehicle; performing a whole vehicle electromagnetic compatibility test on the production trial assembly vehicle; carrying out small-batch wire harness production trial assembly evaluation; and carrying out a wire harness product approval experiment. The comprehensive electromagnetic compatibility low-voltage wiring harness product design method providedby the invention effectively avoids problems possibly generated in a whole vehicle electromagnetic compatibility experiment, and also shortens the period of low-voltage wiring harness product design.
