Even this kind of car air conditioner that looks very simple, but is actually not simple at all, domestic manufacturers can not come up with satisfactory products, which is quite sad.

To be honest, there is no domestic parts company to make automotive air conditioners, but compared with international brands such as Denso, there is still a gap in terms of quality stability and refrigeration effect.

This is also the fact that Guanghui Automobile has to introduce international suppliers in the automatic air conditioning on its own high-end models, and only uses domestic suppliers in the low-configuration manual air conditioners.

"At the beginning, the poor cooperation of suppliers is understandable, but understanding is understanding, everyone has to have an account in their hearts, and when our enterprises develop in the future, those manufacturers who are not willing to cooperate in the early stage will not have to cooperate in the future", Jiang Hui said with a cold face.

Although the core parts and components of the automotive industry are in the hands of foreign-funded enterprises, the automotive industry is a mature industry that has developed for more than 100 years.

No one is truly indispensable!

If you don't use an air conditioner, you can use a Delphi one, if you don't use Michelin tires, you can use a Goodyear one, if you don't use a Johnson seat, you can use a Lear's one, and if you don't use Koito's headlights, you can use a Valeo ......

Of course, the most important thing is that Guanghui Automobile should master some core technologies as much as possible, and at the same time cultivate a group of its own descendant suppliers, a group of suppliers belonging to the national enterprises of the Celestial Empire.

Looking at the world, every major automobile manufacturer has its own descendant suppliers, even European and American suppliers who take the so-called competitive route, they also have their own relatively stable supplier base, not to mention the car companies in island countries and stick countries, and directly invest in their own core suppliers.

As a newcomer in the automotive industry, Guanghui Automobile currently has relatively little core technology, engine technology, although I bought several models of different displacements from Ford, but it is still in the stage of digestion and absorption, and it will take at least two years to achieve independent research and development of upgrading.

In terms of gearbox, it is also directly purchased, of course, this piece can be considered during this year's financial crisis, buy a mature gearbox supplier, and carry out technical research and development on this basis.

In terms of other parts, in addition to stamping parts, Guanghui Automobile has acquired Hagiwara in the island country, and the main stamping parts are currently being made by Hagiwara, leaving a photometric electronics that has just been established for less than two years is considered to be specialized in auto parts.

Other companies such as ATL and OFILM, although they also began to get involved in the auto parts business with the help of Guanghui Automobile, their main business is not auto parts after all.

"I understand, our procurement department has compiled a supply chain blacklist, for manufacturers with different willingness to cooperate, are well informed", Pi Wei is also very unhappy with these international parts giants, but there is not much way for a while.

"What parts do we supply now?"

As the first parts company established by Guanghui Automobile itself, although Guangdu Electronics is a joint venture between Guanghui Automobile and Du Niang, Jiang Hui is still very concerned about her development.

Among the auto parts, electronics-related parts are the most high-tech and will be used more and more in the future.

With the development of automotive technology, in addition to making some breakthroughs in some electronic equipment, it will become more and more difficult for various automobile companies to reflect their new ideas in new models.

This brings out more and more the importance of electronic components.

"At present, they mainly supply body stability control systems and ABS for high-end models, and at the same time, they are working with OFILM and AutoNavi to develop navigation and audio systems, and for our second model, they are also developing instruments and reversing radar," said Pi Wei.

"The body stability control system and ABS are now the best Bosch has done, even the name ESP has been registered and patented, other manufacturers cannot call this name, we consider that photometric electronics is also the first time to develop this system, in order to avoid accidents, we have also introduced Bosch as our ESP supplier", Kato added on the side.

The principle of the stability control system is actually not difficult.

When the car is driving in a corner, if the front wheel first reaches the attachment limit, it will cause the phenomenon of "drifting out", and at this time, the driver can not reduce the turning radius no matter how he hits the steering wheel, so that it is difficult to follow the track, and the steering failure occurs, which is called understeer.

If the rear wheels reach the attachment limit first, the phenomenon of "tail flicking" occurs, the car itself becomes unstable, and the car is quickly pulled to the steering side, which is called oversteer.

The function of the body stability control system is to use the computer to control the engine power output and change the braking force of any one or two wheels to make the vehicle produce the corresponding turning torque to eliminate the phenomenon of understeer or oversteer and improve the dynamic stability of the vehicle.

Stability Control is a development of other technologies, such as ABS and traction control, which must detect whether the wheels are about to lock up and adjust the braking force of the wheels individually.

The vehicle stability control system makes use of this technology as well as the sensors and computational control units used.

The control unit continuously monitors and processes signals from sensors on the steering system, wheels and body to determine whether the vehicle is skiding when cornering.

If slippage is detected, the control unit applies a slight amount of braking to the wheels that need to be braked to help stabilize the vehicle's driving state.

Although its principle is not complicated, but the various logic and control involved in it are very focused on technology and data accumulation, although photometric electronics has also poached a lot of people from Bosch, Denso and other suppliers, and now the prototype of the product has also been produced.

In order to avoid problems with this important equipment, Guanghui Automobile pulled Bosch in as an alternative supplier, which can be regarded as a helpless move.

Of course, in this process, the people of the Guanghui Automobile R&D Center can learn something more or less through the communication with Bosch.

This is probably a little similar to the logic of Tianchao Automobile's "market for technology".

Yes, in the end, this solution must not be able to change to real technology, so to master the core technology, you still have to rely on photometric electronics yourself.

"Well, that's fine, but vigorously supporting group enterprises to enter the field of auto parts is the strategy for the development of Guanghui Automobile Supply System in the future, and you must pay full attention to it, even if the temporary cost is a little more expensive and the quality is a little worse, it is also an acceptable price," Jiang Hui said.
