When a car is moving, how can you tell if there is an obstacle in front of the car?

To list two situations, the first case, when the front is a car, mainly look at the bumper of the car in front, the tail of the car is generally about 42 cm from the ground, when we can see the lower edge of the tire of the front car is about meters away from our car, if we see the lower edge of the bumper of the front car, that is, we see the vertical distance of about 45 cm, the distance from our car is about meters, if we see the upper edge of the bumper of the front car, that is, we see the vertical distance of about 65 cm, The distance from our car is about one meter, when we park on the side, when we see the upper edge of the bumper of the car in front of us a little up, the vertical distance is about 70 cm, then we have to be very careful, because we are only 30 cm away from the car in front.

It's not easy, you need to train. People can get the distance by observing objects with two eyes, but some cars can't see the front of the car, and it is not easy to judge, so it requires conscious practice, which is to get out of the car to observe the actual distance, and then get on the car to feel. Another way is to turn on the headlights and indirectly judge the distance by the position of the lights on the obstacles.

Introduce the stupidest and most effective method, adjust the seat, and the normal test angle, and then ask people to stand at a certain distance to see how far away from the car (the specific distance is adjusted by yourself) and then according to yourself, what you see and the intersection of your car front and your wind shield, make a mark on the wind, so that you know how far away the mark is; After being familiar with it for a while, you can remove the marks on the windshield, and you will naturally know how far it is when you almost reach that point.

Generally, our rear will be equipped with radar or reversing image, which is convenient for us to judge the position, but some of the front of the car is not easy to install radar, of course, I rarely see the reversing image installed in front of the car. For novices, judging the distance between the front of the car and the obstacle will produce a large deviation, and when parking, it will either stop farther or closer. One way to determine the position of the front of a car is to find a reference, and the best reference is the rearview mirror.

The distance between the front of the car and the obstacle and reversing is the difference between the north and the south, how to judge the distance between the front and rear of the car and the obstacle, first fix the location, sit correctly to see the distance between the two points, get off the actual measurement of many times to judge how far you will sum up the experience, practice makes perfect, practice more, see more, observe more, get off the car, measure more, and summarize.

How do we judge the distance between the front car and the pedestrian when we are driving on the road, the same reason, when we see the heel of the pedestrian, we are about 4 meters away from the pedestrian, if we see the pedestrian's knee, the vertical distance is about 45 cm high, we are about about one meter away from the pedestrian, when we see the pedestrian's hips, the vertical distance is about 75 cm high, we are very close to the pedestrian, just brake quickly, because we are only 30 cm away from the pedestrian.

First of all, we are novices, so we have to lower our posture and don't think that we can drive when we get a driver's license, in fact, we are still a long way from becoming a real driver. When we are going to drive a new car, we must have a rough understanding of the size of the car, so that we can reduce the car's friction in the process of stopping, turning, and turning around.

1. Before reversing, you should see and remember the position of the obstacle when you can see the angle of the obstacle in advance, make a judgment and plan the reversing route.

2. When reversing, according to the planned route and at any time through direct observation and reversing mirror observation, grasp the real-time relative position of the car and the surrounding objects, as well as its changes and changing trends and speeds, and adjust the operation accordingly.

3. Make an overall assessment and judgment on the position of the obstacles that can be seen before reversing or the obstacles that can be seen partially and the position of other visible references, as well as the current position and dynamics of the vehicle, and make correct operations based on past experience.

4. Often get out of the car to see, what is the feeling in the car, what is the position under the car, through the training to improve the level of the two one-to-one, you don't have to get off the car again, that is, the old driver said, know where the 4 wheels are and where the 4 corners are. Use your brain to think about it, and you have to find the correspondence you just said through your brain and turn it into your own feelings. Once you find your senses, you'll be in the car.
