Background

With the gradual increase of the automobile occupancy, the traffic safety problem caused by automobiles is increasingly prominent, and governments and vehicle enterprises reduce traffic accidents in various ways. The good or bad visual field of a vehicle directly influences the driving safety, and especially the A-column visual field during turning frequently causes traffic accidents due to the blind visual field area. The difference of the view sheltering of the A column per se from different vehicle types is not very large, the difference of the view blind areas which are connected with the A column and the triangular block into a whole is very large due to the unreasonable position of the external rearview mirror, especially along with the modeling trend that the vehicle height is lower and lower, the side wind water retaining is higher and higher, and the view blind areas caused by the external rearview mirror are more and more prominent. Currently, each vehicle enterprise does not notice the problem in the early period or pay attention to the problem but lacks a quick design evading method in the early period of design.
