The combat head-up display used on the fighter is different, the car TT display system is not only very simple in structure, but also the amount of data displayed is quite small, only the current speed of the vehicle, the speed of the engine, the gearbox gear information, the instantaneous fuel consumption of the vehicle, the average fuel consumption of the vehicle, the oil temperature, the water temperature, the oil pressure, the remaining fuel and so on are closely related to the information of the vehicle, do not expect him to be able to display a lot of information like the head-up display of the fighter.

Speaking of which, the car uses. The head-up display and the head-up display used on the fighter jet also have a deep origin, the car with the head-up. The display was originally a simplified development on the basis of the head-up display of the fighter. Coming over, it can be regarded as an infinitely lite version of the technology of the fighter jet's head-up display, which is a typical "military-to-civilian" technology.

Just with the head-up display used by the fighter. Compared to the requirements of the car head-up display, there is not so much. Strictly, the data displayed does not need to be so much, only the speed of the vehicle and the engine speed need to be displayed. The most important and important data for drivers to know can be.

A more advanced car head-up display, the function will be a little more complete, in addition to displaying the speed and engine speed, it will also be the gearbox gear, the vehicle's instantaneous fuel consumption, the average fuel consumption of the vehicle, and the oil temperature, water temperature and other most basic information of the vehicle is displayed, and some of the more advanced may also add the navigation function on the car to it, of course, not yet, even until Zhang Lan was reborn in 2008, it did not appear, but with this development trend, it is so simple.

This information seems to be a lot, but in fact there are only a few pieces of information, and the acquisition of this information is very simple, although the principle is similar to that of the head-up display used on the fighter, but the difference in the degree of advancement of the two heads-up display technology is simply incalculable.

The reason why Zhang La turned his attention to the head-up display for cars this time is not only to show people and improve the advanced level of Alice Group in automotive technology, but also to show off the technology, but also to consider car safety: all those who have driving experience know that when the vehicle is driving at high speeds. Especially when driving at high speed at night, except for the little place illuminated by the lights in front of you, the other places are completely dark, or when there are many people and cars on the highway, you should pay more attention to the light at night, and the lights of the opposite car are dazzling, and an accident may occur if you are not careful.

But sometimes, in order to understand the driving status of the vehicle and the working condition of the engine, or even want to change the song played by the car audio equipment, the driver will inevitably look down at the data displayed by the instrument on the car or watch the audio equipment displayed in the center console. In this case, if there is a sudden emergency ahead, the driver may not have time to take effective measures and cause an accident.

Although this situation is relatively rare, but in fact, many traffic accidents, is really produced in this way, if the driver's driving age is a little longer, the heart relaxes vigilance, the speed is relatively fast, and it is night driving, this time is the most prone to danger, according to statistics, about 30% of the night traffic accidents are because of this aspect.

To avoid this from happening. Back in the late eighties, General Motors was in the choice of its own premium model Oldsmobile Cutlasspreme display system (HUD). It can display relevant information about the vehicle when driving on the driver's head-up range of the front windshield, and the display position and display brightness can be adjusted. This can prevent the driver from looking down at the instrument in order to understand the speed and other information when driving at high speeds, so as to shorten the blind spot time of the eyeball in front of the eyeball.

To put it bluntly, the on-board head-up display system has an important value in reducing traffic accidents caused by distraction, although when Zhang Lan was reborn, the on-board head-up display system is still the patent of Mercedes-Benz, BMW, Audi, Cadillac and Lincoln and other high-end cars and luxury cars, but Zhang Lan can even predict now that within 20 years, the on-board head-up display system will gradually gain the same important position as the traditional instrument on board, And gradually from the exclusive products of luxury cars to the middle car and even the economic car.

This can be seen from the old Buick LaCrosse flagship model: although the market positioning of the Buick LaCrosse flagship version is more than 300,000 high-end cars, it is still equipped with a car head-up display system, which is also the only car equipped with a car head-up display system among the cars priced below 800,000 on the market - uh, this was only relative to Zhang Lan back then, and now this Buick LaCrosse has not yet been shadowed. It will be another five or six years before we see this car equipped with an on-board head-up display.

Zhang Lan pondered in his heart: since this thing is converted from a military head-up display, and it has undergone infinitely simplified technology. Then things are much easier. Since the company car is needed in the aspect again. I have it in my own hands

with head-up display technology. Then let those old hairmen hurry up and get this T [civilian vehicle head-up display system!

Zhang Lan came to the Alice Electronic Research Laboratory of the Alice Institute of Comprehensive Applied Science and Technology very majestically and high-spiritedly, which is for the entire Alice Research Institute. are quite mysterious research institutes.

I successfully found the chief designer of Alice's electronic research laboratory, who was busy researching avionics and aeronautical display systems, and Varoga, who was busy researching avionics and aeronautical display systems. Zhang Lan said what she meant. Let him divide a small portion of his manpower. Help yourself to engage in a super-simplified civilian version of this fighter head-up display technology: the on-board head-up display (HUD).

"In-vehicle head-up display system?" Heard Zhang Lan finish speaking. Varoga's eyes widened. Looking at Zhang Landi's eyes, it was like looking at a mixture of a fool and a loser. "Such an expensive thing. Isn't it overkill to put it in the car? The traditional instrument system on the car shows enough information for the driver? ”

"It's not like you're going to move the entire head-up display system of the fighter to the car." Facing the look in Valroca's eyes like a fool and a loser. Zhang Lan unceremoniously replied to Valoca, with a look that looked like a little white. "It's just a feature that has to be on the car. It is connected to the on-board computer system through the vehicle's head-up display. It is enough to let the entire head-up display display display the current speed, engine speed, instantaneous fuel consumption, average fuel consumption, oil temperature, water temperature, oil pressure, remaining fuel, etc., which are usually displayed by the instrument system. ”,

"It's as simple as that. Single? Valroga couldn't believe it.

"It's that simple!" Sheet. Arashi nodded affirmatively.

"Isn't that true? Is it a head-up display plus the supporting software and interface between the on-board computer system, plus the corresponding controller and the high-voltage power supply that allows the head-up display to run, through the on-board computer system, so that the data information on the on-board computer system can be displayed on the head-up display when the car is running? Varoga asked.

This guy does know that his own company car. It is equipped with an on-board computer system.

"That's it." Zhang Lan shrugged, . Or how hard do you think it can be? ”

"Such as. If that's the case," Valroga groaned, scratching his scalp, and asked with some certainty, "then what is really needed is the head-up display technology, and the various software and hardware, computer systems, and data bus systems that are matched with the head-up display on the fighter jet are completely useless?" ”

"Nonsense!" ZHANG Lan. replied angrily, "What do I want those things for!" Those things are much more expensive than a car! ”

"But," Valroga hesitated, "wouldn't that be too easy?" ”

"Oh my God," Zhang Lan patted her head depressedly, wanting to get into this guy's head to see what was going on in this guy's head, "Dude, think about it, how much is the most ordinary fighter jet?" At least tens of millions of dollars! How much is the best Longxuan 960 in our company? It's less than 200 RMB! With such a big price difference between these two things, do you think you can use the same thing? ”

After a pause and taking a breath, Zhang Lan said again, "Not only the Longxuan Nine Series will be used, but our Longxuan Six Series may also be used in the future, and even our Qilin Series will be used in the future."

You put something that costs hundreds of thousands of dollars on a car that costs only a few hundred thousand yuan," Zhang Lan asked Valroga rhetorically, "Do you think it's appropriate?" ”

In fact, what Zhang Lan wants to say is: Have you ever been kicked in the head by a donkey? It's just that in front of so many of Valoga's subordinates, I'm embarrassed to say that.

"That's right," Hearing Zhang Lan say this, this guy finally pulled his thoughts out of the ocean of his own research on fighter avionics systems: give hundreds of thousands of dollars to the cost of hundreds of thousands of dollars for car equipment? Either the boss is crazy or he is crazy, and the boss will definitely not be crazy, so it seems that only he is crazy. "So, the cost of this kind of car head-up display system must be very low?"

"Well, it must be very low," Zhang Lan nodded, "I personally think that it is better for this kind of on-board head-up display system to cost no more than 5,000 yuan after mass production, after all, the on-board computer system is already available in the car, and what you want to do is just a head-up display suitable for cars." ”

Speaking of which, Zhang Lan couldn't help but think of those car DVD sound systems in later generations, a set of things that cost about 1,000 yuan, and the black-hearted dealer can increase the price for you by more than 15,000! The same model, except for the car DVD, all the configuration is the same, the price difference between the car DVD sound system and the car DVD sound system and the car DVD sound system is at least 15,000!
