What is the configuration of the HUD? What s the use?

The head-up display is gradually becoming common, and it is no longer only available to luxury high-end models. Even many 100,000-level models are equipped with head-up displays. For example, the JMC Yizhi EV3 with less than 100,000 yuan is equipped with a head-up display as standard.

Between 10-150,000 yuan, SAIC MAXUS D60 and Hanteng X5 are also equipped.

Judging from the records, the first model with a real head-up display was the 1988 Oldsmobile cutlass supreme, but on this car, the information that can be displayed is relatively simple, only the speed information can be displayed, and the Oldsmobile car brand has disappeared.

<> head-up display technology originated from fighter jets, using the principle of optical reflection to project important information on a piece of glass or cockpit cover at the front of the cockpit, and the display altitude is level with the pilot's line of sight, so that the pilot can grasp the flight data at any time as long as he looks ahead.

The technology currently used in automobiles is similar to that of airplanes, projecting driving information onto the front windshield or onto a small piece of glass raised from the center console, so that the driver can grasp the driving information without having to look down at the dashboard.

And at present, the car head-up display can display more information, including vehicle speed, navigation, Bluetooth** calls, ADAS driving assistance systems, etc., can be displayed, and can be displayed in color.

The head-up display is a configuration that avoids the unsafe factors caused by looking down at the instrument, which can improve safety to a certain extent. In addition, it also increases the sense of technology in the car, which can be said to kill two birds with one stone. Of course, at present, this configuration is not very popular, although there are models around 100,000 yuan, but it is still a minority, and it is generally seen in the high-end models of the car.

With the further development of the automotive industry, this icing on the cake configuration may become more and more common in the future.

HUD: Technology? Forced? Or chicken ribs?

The HUD head-up display is actually equivalent to a driving assistance system, mainly to project some driving information directly to the front windshield, or directly project the information onto a transparent screen, the driver does not need to look down at the dashboard and other data during driving, as long as he looks ahead, he can see the relevant driving information, which greatly improves driving safety.

As for whether the HUD head-up display is practical, it depends on the owner personally, although the original intention of the HUD design is to assist driving and improve driving safety, but the use effect in actual life is not so ideal, and some car owners have previously reflected in the process of using the HUD head-up display, because the information is directly projected onto the front windshield, the surrounding line of sight is restricted, it looks very uncomfortable, and it takes a while to get used to it.

Not only that, directly projecting the driving information onto the front windshield will inevitably attract the driver's attention too much, causing the driver to be distracted and reduce the observation of road conditions, and a little attention will cause unnecessary traffic accidents due to distraction.

Therefore, the original intention of the invention of the HUD head-up display is for safety, but the specific use effect is still based on the individual, it is recommended that the driver must pay more attention not to be distracted when using the function during driving, and at the same time, the function only plays a role in assisting driving, or can not rely too much on the function.

Pros and cons of head-up displays for cars

1. Benefits

to improve convenience

The head-up display projects driving information directly onto the front windshield, so that the driver does not have to look down to see the driving status of the car, thus avoiding distracting the driver from the road ahead.

and reduce driver fatigue

The use of the car's head-up display also eliminates the need for the driver to look back and forth on the dashboard information and the road conditions ahead, and the ridge relieves the driver's eye strain.

Second, the cons

Some users find it difficult to adapt

Many car owners say that they are not used to the head-up display system, because so much driving information appears on the vehicle screen at once, and it is easy to distract the driver when driving, which may cause accidents due to lack of concentration.

It is expensive

The cost of a car head-up display is very expensive, and the first of a display needs thousands of yuan, so at present, only a few high-end models are installed with the system.

, the quality is uneven

At present, the market is mixed with hundreds of yuan and other products of poor quality, if consumers do not understand the situation, it is easy to buy inferior products, which not only causes economic losses, but also has potential safety hazards.

The head-up display of the HUD is to project the current speed, navigation and other information onto the photoelectric display device on the windshield, forming an image in front of the glass, so that the driver can see the navigation and speed information without turning his head or looking down. The HUD is designed for the following purposes:

1. The driver-centered design is to make it more convenient for the driver to look at the car screen and operate the knob when driving;

2. The blind operation is to let the driver not leave the front as much as possible;

3. The navigation information can be displayed on the multi-function instrument panel in order to divert the driver's attention as little as possible by watching the navigation.

I firmly believe that many people have found that when some vehicles are driving, there will be some driving information content displayed on the windshield, which gives people a very sci-fi feeling. It is very likely that some people do not know this device, in fact, it is the HUD, so let's introduce the origin and function of the HUD in detail.

The head-up display, also known as the head-up display, is used in military aircraft as a navigational aid. As the name suggests, "heads-up" – the basic principle of electron-optical refraction allows key news information to be projected on glass windows, without the need for drivers to look down.

The HUD began with the electron-optical sight of the warplane, first appeared in World War I, and gradually became widely used in World War II. Nowadays, more and more cars have been equipped with a head-up display (HUD), and it is likely that some people will question whether its role is inconvenient to show off.

In fact, the most important function of the head-up display is to ensure that the driver drives smoothly and puts a lot of energy into observing the real-time road conditions. For example, if you are driving on the highway, if the driver has a few seconds to put the attention into the navigation bar or the driving situation, but do not know that these few seconds, your car has already been dismantled at a very high speed for dozens of meters, the vehicle situation is unpredictable, and finally you will encounter anything unimaginable.

Despite the great role of the head-up display, it cannot be denied that it is still unpopular. Shen Yushou is only standard or optional on some high-end luxury cars, and few car buyers will choose to modify it in daily life, because the HUD head-up display is widely priced and the cost is very large, resulting in many vehicles are not willing to modify.

Millions of car purchase subsidies.

I believe that many people have made it simple that when some cars are driving, there will be some driving information displayed on the front windshield, which feels very sci-fi. There may be some people who don't know about this device, in fact, it is the HUD head-up display, so let's introduce the origin and function of the HUD.

The head-up display, also known as the head-up display, is widely used in military aircraft as a flight aid. As the name suggests, "heads-up" – the principle of optical reflection allows important information to be projected onto the glass, without the need for the driver to look down.

The HUD originated from the optical sight of fighter jets, first appeared in World War I, and began to be widely used in World War II. Nowadays, more and more models have been equipped with a head-up display function, and some people may question, isn't its role just to show off?

In fact, the HUD head-up display is the most cautious, and the important role of the pants is to ensure the stability of the driver's driving, and put more energy into observing the road conditions. For example, if you are driving on the highway, if the driver has a few seconds to pay attention to looking down at the navigation or driving status, but you don't know that in these few seconds, your vehicle has been "blind" dozens of meters at a high speed, and the car conditions are changing rapidly at high speeds, and what you will encounter in the end is unimaginable.

Although the head-up display is very useful, it is undeniable that it is still a niche. Only in some high-end luxury cars standard or optional, few car owners in daily life will choose to install, the reason is that the HUD head-up display is generally higher, and the larger cost leads to many cars are not willing to install.

The head-up display of the HUD is to project important driving information such as speed and navigation onto the windshield in front of the driver, so that the driver can see important driving information such as speed and navigation without bowing his head or turning his head. The distinction between a suspended HUD and a dashboard HUD is as follows:

1. The suspended HUD is fixed on the sun visor above the car driver, and this arrangement results in the HUD information omen will be projected on the upper area of the windshield;

2. The instrument panel HUD is fixed on the center console in front of the driver, and this arrangement determines that the HUD information will be projected in the front area of the windshield;

3. The advantage of the suspended HUD is that the product adaptability is high and the installation is relatively simple;

4. The advantage of the instrument panel HUD is that it is relatively stable and can realize the driver's eye level.
