Therefore, in the process of vehicle development and production, suppliers of automotive electronics and electrical products will Independently carry out various experimental assessments on the electronic and electrical products produced by itself, such as the durability assessment of individual electronic and electrical components of automobile engines or the assessment of high and low temperature impact tests, the assessment of the working conditions of electronic and electrical systems of automobile engines, and the electronic and electrical components in the production process. Quality inspection of electrical product components. These assessments or tests are carried out independently, ignoring the mutual influence of electronic and electrical product components, so the assessment or test results are quite different from the actual operation.

此外,这些考核系统或者检验系统只具备其中一项试验考核或者质量检验的功能,当需要对汽车发动机电子电器进行考核或者检验时,必须要购置对应的考核系统或者检验系统才能进行考核或者检测,成本高且利用率低。 In addition, these assessment systems or inspection systems only have one of the functions of test assessment or quality inspection. When it is necessary to perform assessment or inspection on automotive engine electronics, it is necessary to purchase the corresponding assessment system or inspection system to carry out the assessment or inspection. High cost and low utilization.
