TECHNICAL FIELD

[0001] The present application relates to the field of CMS performance testing, in particular to an indirect field of view CMS whole vehicle integration performance testing system. BACKGROUND

[0002] Indirect field of view CMS is an emerging electronic technology, which is an automotive electronic component that replaces traditional inside and outside rearview mirrors, that is, an optical display component replaces traditional glass reflection components. It has many advantages such as ultra-wide angle, high-definition display, beauty, and technology, etc., and can improve vehicle safety and reduce the probability of safety accidents, and can also provide drivers with a wider field of view and a clearer driving experience. However, as an emerging product related to driving safety, its reliability is very important. If the indirect field of view CMS has black screen, lag, delay and other faults, it may cause trouble or even danger to the driver. Therefore, the functional safety of the indirect field of view CMS needs to strictly follow the relevant standards and processes to ensure that fault-related diagnosis coverage, single-point fault measurement, and latent fault measurement can meet the ASILB level requirements.

[0003] In order to improve the reliability of the indirect field of view CMS and standardize the verification rules of the indirect field of view CMS, the state has issued GB15084-2022 "Performance and Installation Requirements for Indirect Field of View Devices of Motor Vehicles" to make basic requirements for the indirect field of view CMS, that is, system delay. After a period of market verification, it is found that testing only the system delay is not enough, and problems such as light angle, imaging clarity, and frequency flash continue to occur, which shows that the basic standard verification is not comprehensive and cannot truly reflect the performance of the indirect field of view CMS product. SUMMARY
