In previous articles and videos, the importance of shunting is often taught to novice mobile phones. A novice driver asked Coach Shi what is the difference between the driving trajectory of shunting forward and shunting backwards? How can I tell if the front or rear wheels are in the ideal position? The following is to use the perspective of the aerial view to explain to the riders, only for the reference of novice drivers.
The shunting principle of parallel displacement, as well as the wheeling method of borrowing one and returning two, have been explained in detail in previous articles and videos, as well as in tutorials, and will not be repeated here.
First of all, let's go forward shunting, how to judge the driving trajectory of the wheels?
Looking at the picture above, the orange car is parked at the starting position, and the shadow car is parked in the adjusted expected position. When you have determined the target position, you can intuitively determine which side to play the wheel when you go forward. If you want to go to the target position in the picture, you naturally have to play the wheel to the left.
How much to play according to the length of the distance needs, conditions allow, it is generally recommended to play a small amount of wheels, so that it is easy to judge the next driving trajectory.
For example, in the direction of the left, the front of the car will go to the left, walk near the target position, and stop. Some novice drivers say they will not judge whether the car has gone to the ideal position.
Coach Shi gives you two references: one is the corner of the car. For example, the place where the dotted line is drawn in the following figure is the target position boundary. You can let the left car angle pass the dotted line by about half a foot, so that the left front wheel basically walks near the dotted line.
The second reference is the left window corner, where the left front wheel is diagonally below. When you visually measure the left window corner about just past the dotted line, the left front wheel basically arrives near the dotted line.
Here it should be emphasized that you cannot use the driving school point-to-point method, so the error will be very large, and it is necessary to form a sense of space and look at the judgment from top to bottom. If you are really not sure, you can get out of the car, see with your own eyes that the left front wheel is about to reach the dotted line, and then get on the car to find the feeling, and in less than a minute, you can roughly judge the position of the wheel.
The first step of shunting is complete, next, in the right direction (back to the double wheel). The front of the car will be thrown to the right until the car is back in the right direction.
If you have judged correctly before, the car is right behind the car, and the body is parked in the expected position (see the black-edged car in the picture above). Even if there is a slight deviation, you can do another borrowing and paying back a small amount of shunting.
Next, how to shunt when reversing?
Or the figure on the right side of Figure 1 above as an example. When Coach Shi took the trainees to practice shunting, after moving forward to shunting, he then asked the trainees to return the car to the original position. If you want to return to the original position, you must learn to judge the direction of the rear wheel. Or first determine the target position, look at the rearview mirror, and think about which direction the rear of the car is going.
In Figure 1, the target position is on the right. If you want to hit the wheel to the right, the rear of the car will be thrown to the right, and when the right rear wheel is about to reach the dotted position, it is the time to return to the wheel. If the previous step is in the right direction, here back twice is to the left direction, and the rear of the car begins to swing to the left until the car is turning the direction back to the right.
Therefore, whether it is forward shunting or reversing shunting, although you may not be able to see so accurately outside the car, as long as you can roughly judge the position of the front wheel or rear wheel, you can successfully complete the shunting operation.
Understanding the principle does not mean that the operation is no problem, for example, the position reached by the rear wheel can be judged by the rearview mirror. If you are troublesome to adjust the mirror, you can first turn the mirror down during the first exercise, confirm the position of the rear wheel, and then restore the mirror to normal height, and then sit in the car and feel where the rear wheel is? For example, the door handle is diagonally lower, and this virtual point is used instead of the rear wheel.
In order to improve the ability to control the car, shunting is a skill that cannot be ignored. Many people have various scratching accidents because of improper shunting, and when you master the principle, you can avoid similar situations to the greatest extent.
Well, today's topic is here, if you want to systematically learn the relevant driving skills, welcome to pay attention to the history of the coach series of driving columns, series two [all kinds of difficult parking] a total of 28 sections, which explain in detail a variety of shunting, non-glyph reversing, side parking, right angle turning and other driving skills, in accordance with the tutorial guidance for self-learning training, soon can achieve the real unity of people and vehicles.
