[Turn] Driving schools do not teach knowledge (2) Use the inner mirror to determine the distance between the car

[Autohome with car skills] The rearview mirror is a simple and important part of the car, in the daily driving, the rearview mirror, especially the external mirror use frequency is absolutely the highest, relative to the rearview mirror is easy to be overlooked, even some friends never use the interior rearview mirror. In the previous article we introduced the use of external mirrors and determine the distance between the method, "Click here to see the exterior mirrors to determine the distance from the article" So today we will continue to explain the car interior mirror adjustment method and how to correctly use the interior mirrors to determine the distance.

How do I adjust the interior mirrors?

The interior mirrors are relatively easy to adjust, first maintain a proper posture, then map the rear window in the center of the rearview mirror and keep the horizon in the mirror in the center of the Mirror.

Effect and effect of rearview mirror in large field of view

Some in order to reduce the area as far as possible or feel that their exterior mirrors are too small, many car owners will be after the purchase of large-scale exterior mirrors. Large field of view rearview mirror is through the principle of convex mirror, will expand the imaging range to the maximum possible narrowing of the visual blind area, from this point of view, the effect is obvious, but the mirror in the scene is deformed, distance sense will cause deviation. In addition, some brands of cars in the exterior mirrors are also used in the external mirrors with curvature, to increase the external visual area.

Of course, no matter what kind of rearview mirror, no matter how the adjustment is just as far as possible to narrow the blind area, the blind spot is absolutely unavoidable, so when necessary to turn back is the most effective way.

How to determine the distance between the interior mirrors?

There are many ways of judging the distance in the rearview mirror, but we find that these methods are confined to the exterior mirrors and are not mentioned for the use and judgment of the interior mirrors. We know that the rearview mirror in the car plays a key role in reversing, whether through the rearview mirror can determine the distance between the car, we continue to experiment today.

The use of the test car for the Great Wall hover, Volvo S60 and Peugeot 206, the choice of these three cars mainly want to test the SUV, sedan, hatchback for the interior mirrors the effect of the control distance is consistent.

Experimental methods: We will three vehicles parked in front, from the rearview mirror to observe the position of the rear car, and after the rear side of the car to focus on the back of the next window, rear headlights overlap front of the rear window along, after the vehicle under the front of the front windshield overlapping front window along as the reference point, observe the different vehicle distances have changed.

Scene 1: After the front of the car and the rear of the vehicle under the window of the following coincidence as the subject

SUV in front: SUV body High, the sight of natural good. At this time inside the rear-view mirror can be fully mapped in the lens, although the rear window area is not small, but the lower edge of the rear window is not low, so that the reflected line of sight is relatively flat, when the rear bumper overlapping line of sight, at this time two vehicles distance of 12 meters.

Sedan in front: due to the low seated position of the sedan model, the angle between sight and ground is very small, and the rear window of the sedan is inclined. So although the rearview mirror area and SUV model similar, but the true map of the field of view is not large, the observation of the rear bumper overlapping line of sight, the car is 16 meters apart.

hatchback in front: but from the appearance of interior mirrors, the hatchback from the view is actually better than the sedan, and SUV models have a little similar, rear window angle paranoid, can make it appear in the rearview mirror in the field of vision has improved. and the car window area relative to the body ratio is larger, so observe the rearview mirror when the rear wheel has been covered, the two vehicles are close to the distance, only about 5 meters.

Scenario 2: The machine cover overlaps the line of sight for reference

SUV in front: similar to the principle mentioned earlier, due to the type of vehicle and the angle of view, although the rear view from the rearview mirror, after the car grille has been blocked, but at this time the two vehicles still have a distance of 6.5 meters.

Sedan in front: The same reason, the three-car rear window cross-sectional area small, and some models tail up, to a certain extent, affected the line of sight, but at this time after the car still a distance, up to 8.5 meters, a safe distance.

hatchback in front: the rear window is straight, the area is very large, which led to the rear of the car grille overlap The driver's line of sight is only about 2.5 meters, if in high-speed driving, you can tap the brake tips after the car to keep the distance.

Scene 3: Line of sight with the rear of the car in front of the wind glass coincident

SUV in front: Although at this time after half the car body has disappeared in the mirror, if you are reversing, big can not panic. As the SUV body is high, the car parked close, the car will naturally be blocked half the body, at this time the two vehicles are about 2.7 meters apart.

　　Sedan in front: for sedan, the tilt of the rear window will affect the visual judgment, although the same is the windshield under the overlapping line of sight, but considering the line of sight and sedan protruding tail, at this time the car is only 1.5 meters apart.

　　hatchback in front: This is a hatchback need to note, if reversing storage, after the observation mirror after the car is gradually buried in sight to be very careful, so the hatchback rearview mirror inside the view of the relatively intuitive, when the rear car grille was buried into the sight, the two cars only 1 meters more distance, And when the line of sight has not been half of the machine cover, the two cars are very close.

Conclusion:

Some people may ask, outside the rearview mirror to determine why the distance is not affected by the model, but the interior mirrors are different models of the impact of such a large? We're having a show.

, the middle of the sedan model due to low seated position, the rear window tilt angle is large, so the driver's observation line of sight is not good, the angle of view of the rearview mirror and the horizon is small, so observe the same marker, the actual distance from the furthest.

Above the SUV model because of the high body, relatively speaking field of view to open some, you can observe the range is larger and wider, when the marker to reach the edge of sight, compared to the three-car model of the experimental distance is close.

And the hatchback because of the small body, the window area is not small but the proportion of the car body, so the relatively good line of sight, when the marker to reach the edge of the hatchback line of sight, the distance is actually very close.

Based on the above points are not difficult to see, outside the rearview mirror to determine the distance is not too much to consider the model factors, we are not a big difference. However, the car rearview mirror to determine the distance is difficult to give a clear standard, and the vehicle shape, body shape and so on have a relationship, so we pass three common models to everyone as a reference, in practice, you also have to target the characteristics of their models, find the right mark points to accurately determine the distance is the most insurance.

It is also important to add that the previously mentioned large vision mirrors will skew the visual perception, the actual vehicle distance will be closer than the observation, this situation is reflected in the internal rearview mirror, but the difference is that the interior mirrors are usually able to fully map the rear window, Then through the back window as a reference to observe the car in the rear window position is basically no error situation.
