The invention relates to the field of automobile design, and particularly to a method for checking the influence of an automobile combination instrument on safe driving vision. The method includes thefollowing steps: eye ellipse envelopes are used as light sources to emit light into the combination instrument through an inner side of a steering wheel rim according to upper tangent lines and lowertangent lines of the eye ellipse envelopes, reflected light is observed, whether the reflected light enters a transparent area of a front windshield or not is judged, if the reflected light of S3 enters the transparent area of the front windshield, the reflected light entering the combination instrument from the transparent glass area will enter the eye ellipse envelopes to cause dazzle, and if the reflected light in S3 does not enter the transparent area of the front windshield, dazzle will not be caused to a driver. The method provided by the invention can effectively overcome defects of alimited application scope, the need for making complicated lines during checking and low efficiency existing in the prior art.
Description
technical field [0001] The invention relates to the field of automobile design, in particular to a method for checking the influence of an automobile combination instrument on the field of vision for safe driving. Background technique [0002] The car combination instrument is an interactive interface between man and car, which provides the driver with the required car operating parameters, faults, mileage and other information, and is an essential part of every car. The most prominent feature of modern instruments is functional modularity. Usually, when assembling instruments, a complete system can be obtained by combining several functional modules on the basis of custom PCB. [0003] It is very important for the driver to have a good vision while driving. However, the combination instrument, central control screen and other equipment inside the existing car will reflect light when the external light shines in through the transparent area of the front windshield glass o...
