Don't panic on the up and down slopes? You don't have to look down at the meter when you drive. You can also stop by looking at the screen. Yes, with the help of technology, today's cars have many small configurations that assist in driving. These functions are already very powerful.
This article refers to the address: http://
However, as the saying goes, a penny is worth the price. Usually, many configurations that look very "upper" are owned by high-end models. So, isn't all the functions usually used? Is it worth spending more money to buy a high-end one for more than one or two configurations? It's really necessary to understand clearly, don't buy it and find it, usually it doesn't work!
It is no longer difficult to park it.
1, automatic parking
Although the function of automatic parking has been out for several years, it has not been widely popularized so far, so it can be seen that it still has a certain technological content. In the past, most people got the most intuitive knowledge by watching advertisements. Oh, it turns out that parking can be done automatically with the push of a button! However, what I want to tell you here is that it is not that simple.
First of all, the automatic parking function of each car brand is different. Take BMW's automatic parking function as an example. When the system scans the parking space, the forward speed can reach 35km/h. The success rate of scanning is very high. The system allows multiple movements before and after, until the parking space is completely stopped. How important is this scanning function? To know that in order to use the automatic parking function, the car's system must first be identified as a parking location. Some car brands have high requirements for scanning speed. For example, the Lexus automatic parking system requires that the driving speed should not be higher than 5.5 km per hour, otherwise it will be easy to exit automatically.
In addition, an automatic parking system like the Mercedes-Benz B-Class is always in a ready state at a speed of less than 36 km/h, without the need for the driver to manually start. However, most other car brands need to be opened in advance, otherwise you will encounter the embarrassment of forgetting to open in advance and reversing once. In addition, different automatic parking systems have different automatic parking capabilities, such as the requirements for the length of the parking space, and the need to control the throttle and brakes themselves. Therefore, the automatic parking function is really easy to use, but it is not omnipotent, because not all parking spaces can be used, and it is easy to hit other people's cars.
2, panoramic reversing image
Speaking of the reversing image system, some people may think that this is nothing new. That's right, reversing assistive technology has long been popular, from the most primitive "reverse, please pay attention" to the early warning sound, and then to the visual reversing image, has experienced several generations of technological evolution. However, the full-motion reversing image system is not so simple. At present, there are not many car companies that actually use the production car.
The so-called reversing image system is a bird's-eye view of the surrounding environment of the vehicle through four super wide-angle cameras. At this time, the driver's perspective on the screen is like looking at his car and the surrounding scene in a vertical angle. The reporter once tried to drive a car that was covered with all the glass, and only used the panoramic reversing image to carry out complicated reverse movements. In contrast, the comparison can only look at a few lines of the reversing image, or listen to the cue, you can use the panoramic view to reverse the function is really very practical. In addition, taking the panoramic reversing image on the model of Tianzhu as an example, the system can be turned on when moving forward, but the speed cannot be fast. At this time, if you move in a very narrow space, this system is undoubtedly very practical.
Driving lazy artifact
1. Uphill assist and automatic parking
First, let us know about the uphill assist system. Everyone knows that starting a slope is a skill that must be learned when learning a car. Especially in big cities, when traffic jams or fees are paid on the upper slopes, parking on the slope often occurs. At this time, if you follow a car behind, is it annoying? Uphill assistance is used to solve this trouble. In order to prevent the vehicle from slipping back when the slope starts, the uphill start assist can temporarily apply braking to the four wheels to prevent the vehicle from sliding down.
This feature may be familiar to everyone. However, some details should be reminded that the start of the uphill auxiliary function requires certain conditions. First of all, it must be at rest, and it is necessary to press the brakes hard. In addition, similar to the Uphill Assistance (HAC), there is an automatic parking function (AUTOHOLD). This function is relatively more foolish and more convenient, not only on the slope, even on the ground, at the time of waiting for traffic lights, and there is no time limit. The two are the same, stepping on the throttle, the system will automatically unlock.
2, downhill auxiliary
With uphill assistance, there is naturally a downhill assistance. The uphill assist is to prevent the vehicle from slipping backwards, while the downhill assist system is to help the driver to better control the vehicle to descend slowly. When the system is started, the driver does not need to step on the brakes, as long as he grasps the steering wheel and controls the direction. Through practice, the reporter found that the function of the downhill auxiliary system of different car brands is almost the same; however, for the speed of the downhill, this is slightly different, some are very slow, and some are faster.
However, it must be pointed out that the downhill auxiliary system is not very useful in practical daily life. It is not convenient to control the speed by stepping on the brakes. When compared with the extreme, it is in the extreme off-road, in some very steep On the slope, the driver may not see the road below. When the system is turned on, he can liberate his feet and look out the way.
Makes you more convenient
1, head up display
When driving, the speed and speed are often seen by the driver. Now there are various multimedia, temperature, tire pressure monitoring and other information. How do you think? Generally speaking, it is not looking down at the dashboard area, or looking to the right. The screen of the console. But no matter which action, there is a drawback: it will take at least one second. And if you drive at a speed of about 100 kilometers per hour, the distance of this one-second gap is already 28 meters.
The heads up display will work at this time. Just like the high-tech LCD screen on the fighter plane, the driving data is displayed on the front display. This technology has been applied to the car. In this way, the driver does not have to look down or look sideways, and can directly view all the car information at a glance. It should be noted that when looking at the head-up display, it will be distracting, not to say that it is absolutely safe.
2, night vision system
When it comes to night vision systems, it is best to count BMW. BMW's night vision system (BMW Night Vision) is a driver assistance system in BMW's "ConnectedDrive". This night vision system features pedestrian recognition, and the night vision system automatically recognizes pedestrians and alerts you in the dashboard and HUD head-up display.
It works by using a thermal-sensing imager with infrared technology that detects pedestrians and animals within 300 meters of the front and displays them on a central monitor. The stronger the object's thermal radiation, the brighter the image in the BMW night vision system. At a speed of 100 km/h, the driver can see the hot radiating object as early as 5 seconds before the headlights are illuminated. The far infrared illumination distance is about 300 meters, which greatly exceeds the illumination range of the far/low beam. With this system, you can improve the safety when driving in a dark place.
