A rear view verification device, evaluation method and improvement method of an interior rearview mirror

Abstract

The present invention proposes an interior rearview mirror rear view verification device, evaluation method and improvement method, including an adjustable interior rearview mirror, an adjustable seat and a rear windshield adjustment mechanism, and the adjustable interior rearview mirror includes a rotating assembly and a telescopic assembly And the interior rearview mirror, the interior rearview mirror is installed in the car through the telescopic assembly and the rotating assembly; the rear windshield adjustment mechanism includes the ring body, the left and right adjustment assembly and the up and down adjustment assembly, and the left and right adjustment assembly and the up and down adjustment assembly are connected with the ring body Based on the device, the invention establishes the correlation between the subjective evaluation experience and the design index, and establishes the evaluation and improvement method of the subjective evaluation problem and the like. In this way, in the early stage of project design, the field of view of the interior rearview mirror of any developed model can be verified and evaluated to determine whether it meets the real needs of drivers of different heights for observing the rear view area, thereby ensuring the competitiveness of product design.

Description

technical field [0001] The invention belongs to the technical field of vehicle ergonomics, and in particular relates to a rear view verification device for an interior rearview mirror, an evaluation method and an improvement method. Background technique [0002] In automobile development projects, the rear view of the interior rearview mirror is an essential design and verification work. On the one hand, it is necessary to meet GB15084-2103 regulations on the field of view of the interior rearview mirror, which is the most basic design requirement; on the other hand, the driver can actually observe the rear field of view through the transparent area of ​​the interior rearview mirror and rear windshield glass The size and whether the transparent area is blocked is also an important design content, which involves the driver's subjective perception of the rear view, and can reflect the people-oriented safety design concept. [0003] At present, in the development of projects i...

Problems solved by technology

The above requirements cannot reflect the actual driving experience at all. First, drivers with different heights and different driving habits have different eye points; The size of the transparent area of ​​the rear windshield glass, rather than a straight line on the road; in addition, there may be a phenomenon that the rearview mirror can only see part of the transparent area of ​​the rear windshield in the design

The problems described above are difficult to quickly and accurately identify through design indicators. That is to say, there is a lack of subjective evaluation means in the early stage of design (design indicators cannot replace subjective evaluation feelings). The problem of vision behind the mirror (for example, the transparent area of ​​the glass cannot be completely seen through the rearview mirror, or the transparent area of ​​the glass seen is too small to affect the rear vision, etc.), the problem is difficult to change, and it brings design complaints and even safety hazards
