Countercurrent 1982

In fact, as early as the 60s and 70s, both Japanese and Americans were keen on researching car navigation systems. In 1961, an American company designed an original navigation system based on wireless signals. In 1966,

General Motors has developed an assistance system called D air, which is considered to be the whole body of Gianxing now. In 1973, the Japanese International Trade Industry Corporation and Fuji Heavy Industries jointly launched the Japanese car navigation system research project, which is the so-called integrated car traffic control, but in general, these research results are also

It has two major characteristics. The first is high cost, and the second is low efficiency. Naturally, it has no meaning of popularization.In that era when wireless satellite communication technology was underdeveloped, although the research and development of car navigation systems was technically advanced, it was actually a thankless task, because many products could only be achieved when the corresponding technology reached the level.
To a certain extent, there is room for development. In the 80s, Honda launched a car navigation system that is more reliable than the inventions of the previous 20 years. It has two points of progress. The first point is based on real maps, and the second point is to become an extension of new cars. Optional
place.However, the earliest car navigation systems did not have GPS, and used gyroscope positioning. There are two wires and a helium gyroscope to determine your position. The current position is displayed with dots on the CRT display. All calculations
All are provided by a 16-bit computer. Compared with today's navigation solutions, it is very expensive. The first generation of the product was priced at $1, which is about 2746/1 of the price of the Accord that can be equipped with it. .The person who really changed the fate of car navigation was Ronald Reagan. In 4, when US President Ronald Reagan signed an executive order allowing civilians to use GPS technology, he may not have known that he was in the book
write history.You know, the earliest global positioning system was developed for the needs of the U.S. Department of Defense in the 60s. It was never considered, because GPS had very important military value at that time, and it coincided with that time

During the Cold War between the United States and the Soviet Union, Americans have always regarded this technology as a military trump card, so they did not consider civilian use at the beginning.

The order signed by Reagan made it possible for the public to use GPS.Although GPS is open to civilian use, in fact, no company connected this communication satellite technology with vehicle navigation throughout the 80s. The reason for this is very simple. The main reason is that the cost of vehicle navigation systems is too high. , For example, in the mid-80s, a car navigation system launched by a company in California, USA, used an Intel 8088 microprocessor and a tape drive, and suitable tapes cannot store a large amount of data.

According to the information, in the Los Angeles area alone, 4 tapes are needed, and the use of navigation requires frequent replacement of the tapes. The price of this system is 1500 US dollars, which is cheaper than Honda's gyroscope, but it is still not cost-effective.

Until 1987, Japan gave the automotive world two vague but important advances in navigation technology.

The Toyota Crown sedan was equipped with a dead reckoning navigation system with a built-in CD Rom for the first time, and was equipped with a color display for the first time, but these attempts in the 80s were still unsatisfactory in terms of navigation accuracy.

After entering the 90s, after the car navigation system adopted GPS, the accuracy began to increase significantly. …

And the first company to use the GPS navigation system is Mazda, which has been researching black technology for a hundred years.

Mazda used the GPS navigation system on the Rotor sports car launched in 1990, and in the following years, almost every automaker began to explore and experiment with the capabilities of GPS navigation.In 1992, Toyota developed the first car with voice-activated GPS navigation. In 1, BMW launched the first car equipped with GPS navigation system, and the technology of this GPS navigation system was developed by
Provided by Philips.

Another year later, in 1995, American manufacturers introduced the first cars with GPS navigation systems.Judging from the research and development of car GPS navigation systems in various countries, Duan Yun started relatively early here. He has been planning to develop car GPS navigation systems since the 1s, and two years ago, he achieved

A major breakthrough has been made. In fact, Tianyin Group has mastered the current most advanced GPS navigation system related technologies.

However, after the technology is researched, whether it can be used on a large scale is another matter.Since Duan Yun first invested in the automobile industry in Shenyang, Jinbei Automobile Factory produced some cheap small and micro cars, and the price has always been around 6 to 8.
It has only just reached a little over 9. Cost control has always been one of the most important indicators for the technological development of Tianyin Group's automobile industry.Although the car GPS navigation system developed by Telling Group has been improved many times, the cost has been greatly controlled. In particular, Telling Group can produce its own chips and single-chip microcomputers, so that it has a unique advantage in the development and production of car navigation systems. Although the cost of the latest generation of car navigation systems is far lower than that of European and American products, it still needs about RMB 7000 to 8000, which accounts for almost the entire

More than 1/10 of the cost of the car, if it is really equipped on the car, the price advantage of Tianyin Auto will be greatly weakened.Moreover, for the current Chinese car users, the GPS car navigation system is not just needed. The demand for this kind of navigation system is not even as good as that of the car radio, and the accuracy of this system still has a big gap with the GPS navigation system of later generations. , so generally speaking, the cost performance of this set of equipment is not high. If it is forced to be installed on the car, it will definitely affect sales. Therefore, in Duan Yun's opinion, the current system can only

As a high-end optional electronic product, it is up to the customer to decide whether to install it.However, in any case, the car navigation system will definitely become an essential accessory of the car in the future, so it is very necessary to start research and development and investment in this technology now, which is a long-term technology of the car industry.
The tactical strategy must not be abandoned halfway.Moreover, in Duan Yun’s view, China’s auto industry cannot always follow the low-end route, it must also have its own luxury brand, and if you want to create a Chinese luxury car brand, you must have your own “black technology”

Since it is difficult to achieve cornering overtaking in the three major parts of the car, Duan Yun can also find another way to make some major breakthroughs in the electronics of the car, and this is also the advantage of Tianyin Group.For a whole morning, Duan Yun, led by Chen Qiao, visited the construction of Shenyang Heavy Truck Base. In the afternoon, the two of them came to the experiment of the Automobile R&D Center, where Duan Yun was preparing to test drive the new car.
