Parking warehousing is very difficult for many novices. Under normal circumstances, the most important thing to pay attention to when reversing is the low obstacles on the side of the car body, ground depressions, etc., as well as fire hydrants, cement piers, and limit posts. In order to cope with such a "sinister" environment, we have to rely on rearview mirrors .
There are two main types of rearview mirror mirrors. One is a flat mirror. As the name suggests, the mirror is flat. The term “surface radius of curvature R infinity†is used to describe the term, which is the same as that of a home mirror. This plane mirror is often used as an interior mirror. The other is a convex mirror, the mirror surface is spherical, with a radius of curvature of different sizes, its image is smaller than the visual, but the field of view is large, like the role of the camera "wide-angle lens", this convex mirror is often used as an external rearview mirror And the lower rearview mirror.
Experienced drivers only look directly through the windows when they are directly reversing at long distances. Most of the rest of the time they use the rear-view mirror to rewind. When looking through the rear-view mirror and reversing the vehicle, there is no need to go back. It is easier to take into account the dynamics of the front end, and it is not easy for the front to wipe off obstacles.
The co-driver side mirror is a convex mirror with a slight curvature. The reflection range is wide, but there is no real sense of distance. The scenery in the mirror looks farther than it actually is. In addition, because the scenery in the mirror is deformed, it is difficult to use this kind of mirror to judge whether the body is parallel to the roadside. The main use of this mirror in reversing is to observe the obstacles on the right side of the body and the distance of the tire from the edge. In order to clearly understand the condition of the road surface on the right side, the angle of the mirror may be adjusted downwards when reversing the vehicle. (Some of the more advanced car mirrors on the side are linked with the gearbox . Turn down 10 to 15 degrees.)
According to each person's driving habits, the rearview mirror adjustment also depends on the specific circumstances. Adjustments need to pay attention to the following issues: 1 To adjust the three mirrors , we must first adjust the sitting position, and then adjust the mirror. 2 For interior rearview mirrors, the left and right positions are adjusted to the left edge of the mirror just to the right of the image in the mirror. 3 For the left-side rearview mirror, the top and bottom positions center the distant horizon to the center, and the left and right positions are adjusted to 1/4 of the mirror area occupied by the body. 4 For the right side mirror , because the driver's seat is on the left side, it is not so easy for the driver to grasp the right side of the vehicle body, plus the need for on-street parking, and adjust the up and down position for the right side mirror. When the ground area is larger, it accounts for about 2/3 of the mirror.
The driver's side mirror is a plane mirror, and its scope of reflection is not as wide as the co-pilot side, but it has a real sense of distance. With it, it can more easily determine the distance between the vehicle body and the rear obstacle, and some of the dividers The parking space can also use it to judge whether the body is stopped "positive".
