济南奔驰汽车维修人员为您分析：
People who drive know that looking in the rearview mirror can create blind spots, which are a very scary thing. Small things can cause property damage, while big things can harm lives. Jinan car maintenance drivers who install it generally believe that the small round mirror in the rear view of the car is an ideal auxiliary product to ensure driving safety, increase the viewing angle, overtake, and change lanes. The small round mirror is also an ideal parking aid tool, usually installed below the left and right rearview mirrors. Below is an analysis by Jinan Mercedes Benz automotive maintenance personnel for you:
优点一
Advantage 1
小圆镜的加装能让驾驶员坐在车里更好的观察车身侧面、后轮的情况，如果盲区内有车过来可以及时发现，变道扭头一看，后面的车轮都清清楚楚的，减少事故的隐患。
The addition of a small round mirror allows the driver to better observe the side and rear wheels of the vehicle while sitting in the car. If a car approaches in the blind spot, it can be detected in a timely manner. When changing lanes and turning around, the rear wheels are clear, reducing the risk of accidents.
优点二
Advantage 2
新手倒车时，有个小圆镜，能让倒车更简单，侧方停车的时候可以看右侧车轮的相对位置。可以很好地让新手司机培养车感，特别是在入库停车、后车时，能更好地掌握路况。
When beginners reverse, there is a small circular mirror that makes it easier to reverse. When parking on the side, you can look at the relative position of the right wheel. It can effectively help novice drivers cultivate a sense of driving, especially when parking in the garage and driving behind, to better grasp the road conditions.
优点三
Advantage Three
除新手需要装小圆镜外，对于经常跑山路或崎岖路、狭窄路段的司机，也是非常有必要，因为装上小圆镜后，驾驶员就可以观察更好地观察路况，以便更好地纠正右侧车身和道路之间的距离，尤其是两车同时经过时，后视镜上的小圆镜作用就更明显了。
In addition to novice drivers who need to install small circular mirrors, it is also very necessary for drivers who frequently run on mountain roads, rough roads, and narrow roads. After installing small circular mirrors, drivers can observe the road conditions better, in order to better correct the distance between the right side of the vehicle and the road. Especially when two vehicles pass by at the same time, the small circular mirror on the rearview mirror has a more obvious effect.
优点四
Advantage Four
小圆镜是比较便宜的，某宝或汽车维修店都有很多选择，且安装相对简单，安装位置可以根据不同车辆和驾驶习惯进行决定，有较好的实用性。
The small round mirror is relatively cheap, and there are many options available in certain treasure or car repair shops, and the installation is relatively simple. The installation position can be determined according to different vehicles and driving habits, which has good practicality.
尽管后视小圆镜优点不少，但它也不乏争议。
Although there are many advantages of a small circular mirror for rearview, it is also controversial.
争议一
Dispute 1
如把小圆镜贴在后视镜上角，能看到本车后车轮，但是后视镜视野遮挡了；若装在后视镜右侧，又把原后视镜右侧视野挡掉了；贴后视镜内侧下角，只能看到车后轮，但是后视镜视野中的道路车辆，却什么都看不到.....
If a small circular mirror is attached to the upper corner of the rearview mirror, the rear wheels of the vehicle can be seen, but the field of view of the rearview mirror is obstructed; If installed on the right side of the rearview mirror, it blocks the field of view on the right side of the original rearview mirror; By sticking it to the inner lower corner of the rearview mirror, you can only see the rear wheels of the vehicle, but in the rearview mirror view, you can't see anything from the road vehicle
争议二
Dispute 2
使用小圆镜时候，往往注意力会过度集中在小圆镜上，加之小圆镜太小，会导致判断后车距离有点失真而造成与前车追尾情况。
When using a small circular mirror, attention often tends to be overly focused on it. In addition, if the small circular mirror is too small, it can cause distortion in determining the distance between the rear car and the front car, resulting in a rear end collision.
争议三
Dispute Three
有些新车在R挡会自动向下翻反光镜，有这种功能的车辆也就用不着小圆镜了。
Some new cars will automatically flip down their mirrors in R gear, and vehicles with this feature no longer need small round mirrors.
那么，后视小圆镜到底是否需要安装呢？
So, does it really need to be installed?
如果经常在道路比较窄小的地方行驶，那小编建议可以装配小圆镜；对停车技术不放心的驾驶员，也可以配一对，这样就可以很清楚的看到停车线，不必再调节后视镜来看或者伸出脑袋去看了。
If you often drive in narrow areas of the road, the editor suggests fitting small circular mirrors; Drivers who are not confident in parking technology can also pair them up, so that they can clearly see the parking line without adjusting the rearview mirror or sticking their heads out to look.
此外还要提醒大家，安装小圆镜后切不可以把小圆镜代替后视镜的作用，观察车后情况主要还是靠车上的后视镜，记住小圆镜只能起到辅助作用，扫一眼即可，不能以在小圆镜里判断的车距为依据变道或超车。更多事项就来我们网站

In addition, it is also important to remind everyone that after installing the small circular mirror, it is not allowed to replace the function of the rearview mirror. Observing the situation behind the car mainly relies on the rearview mirror on the car. Remember that the small circular mirror can only serve as an auxiliary function, just a glance, and cannot be used as a basis for lane changing or overtaking based on the distance judged in the small circular mirror.
