On the morning of May 18, the Chery DHT mixed special gearbox completed its own offline ceremony in low-key landmarks in Wuhu.
The mystery behind Chery DHT
Don’t look at the entire offline ceremony is quite low-key, But this DHT technology content is not a vague. At the Shanghai Auto Show in the near, Chery initially released some information about DHT. This time, we have seen some new highlights.
For this DHT positioning, there is always a clear self-evaluation of Chery in the research and development sector – “The World”.
What is the first in the end?
First, Chery DHT is the first Chinese brand and the only DHT system driven by a dual motor. In addition to Chery DHT, there is only one motor to participate in driving vehicles.
Under the double motor drive, Chery DHT can achieve 9 working modes of single / dual motor drive, increase, parallel, transformer direct drive, single / double motor energy recovery, driving / parking charging The more work mode is, it is clear that specializes can be made for a variety of driving scenarios, thereby improving the working efficiency of the entire system.
At the same time, the dual motor can also better adapt to the process level of the current motor and the auxiliary system components in China, reducing the dependence on importing technology. It is better to achieve autonomous control, avoiding the possibility of “breaking” in the field of core parts in the core parts.
Second, based on dual motor driven configuration base, Chery DHT has the world’s largest 11 combination gear.
In the fuel household car market, the automatic transmission of the current production vehicle is the most gear of Honda’s 10t, in general, the more gear, the more smooth, the better the power, the more oil, the same, Chery DHT The world’s largest 11 gears will also have advantages in this area.
However, it may generate a misunderstanding, which is that Chery’s DHT can only achieve 11 gear, which is not the case.
According to the latest information released by Chery, when the DHT system is in different working scenes, the built-in control system calculates the optimal work gear in real time, with Chery original Fio fixed-point injection oil-cooled motor technology, TEM Ultra-high-efficiency dual motor power distribution technology, super smooth TSD double-axis drive design, etc., can achieve dynamic, smooth and economical balance.
The role of specific per technology, there may be special interpretation, but simple understanding is that through a two-motor and a gear combination, with a series of Chery original black technology, this set DHT can make the vehicle run fast on the basis of being “card neck”, but the power flow is not frustrated, and the fuel consumption has a low thief.
The engineer is of course the use of data:
– “China’s highest” full box torque density 35N • m / kg, input torque 510n • m
-NEDC operating electric drive average efficiency GT; 90%
– maximum transmission efficiency gt; 97.6%
– low Funding rate of electricity mode, 50%
– Pure electric total sound pressure level 75 decibel 
– Design life is 1.5 times the industry level
can be said to It can be said that it is a leader in the industry.

Currently, the Tiggo 8 PLUS insertion version of this DHT system has completed unveiled at the Shanghai Auto Show, which is expected to be pushed to the market in the second half of this year.
In terms of key data, this Tiggo 8 PLUS is expected to provide two-drive and four-wheel drive version, and the four-drive version of the zero acceleration can run into 5 seconds, 100 kilometers comprehensive fuel consumption LT 1L.
If we combine the 100 km of pure electricity, we can directly change the B state fuel consumption of the Industry and Information Technology of this car (no energy conversion of fuel consumption), that is, the so-called feed oil consumption Will be less than 5L.
That is, this Tiggo 8 PLUS insertion will also have the characteristics of strong acceleration and low fuel consumption, the largest, long-term The credit is the “world first” DHT system.
What is the mixed master?
said that many people may be very surprised, have been obsessed with Chery for engaging the engine, how is it? Advanced hybrid system?
This has to start from the days of Rui R & D in this day. 
It is 22 years ago, that is, on May 18, 1999, Chery’s first engine officially launched, and in the age of “technical self-confidence”, Chery can be said to be in China. Zero breakthroughs in the field of automotive core components.
At that time, Chery has experienced the fight against “do not achieve the Yangtze River”, and after that, Chery Divide the AVL to learn art, and then go to the hard work to achieve complete research and development, step by step to stage in the engine field, from “bronze” to “king” counterattack.
This year’s burst of red all net Chery 2.0T engine horsepower test has also been very directly verified at the world-class strength in the engine field.
At present, Chery is still continuing to develop by Miller circulation as the main technology, thermal efficiency is targeted 41The fifth generation of the percentage of the fourth-generation engine, the thermal efficiency 44% is also developed, and the challenge 50% is generally considered to be a number of engine thermal efficiency limits.
Seeing this, I believe that many people will understand that the spatial in which pure internal combustion engine technology is crushing, so there will be a variety of “elimination of fuel trucks”. But the fact is not so exaggerated, and the pure fuel car is indeed slightly micro, but does not represent the engine technology disappears. It will be used as part of the hybrid vehicle, and has a long-term new energy vehicle such as pure electric vehicles. 
What will I coexist?
According to the latest “Energy Saving and New Energy Automobile Technology Road Line 2.0” of the Chinese government, in 2035, China plans to achieve domestic automobile sales, representatives representing energy-saving vehicles and pure electric motors represented by mixing. New energy vehicles each account for 50%.
So even if it is 15 years, there will be more than 10 million car sales of the car, who can take it out at that time, who can take the dry goods in the field of mixing and new energy technology, who There is hope for the high school car industry.
Chery can certainly see this trend, and it is more than 20 years ago.
In December 1997, Toyota’s first generation Prius was officially released in Japan. This is the first quantification model based on Toyota THS hybrid system. Today’s THS has become the most successful mixing system in the world, with a cumulative sales of more than 15 million.
At that time, the name just gave the name, and the Chery of the “lack (engine)” problem day and night is aimed at this frontier. Technical trends, although there is no strength and resources at that time.
After 1999, after the first engine offline, Chery quickly established the Clean Energy Automobile Project Group, starting the development of new energy technology such as electric vehicles and all-aluminum lightweight body, 2000 , Chery’s hybrid research and development also officially launched.
In 2000, in participating in an electric car related schoolWhen the enterprise cooperation research and development project, a Chery engineer had a strong interest in Toyota’s THS mixed, so he spent four months of the feasibility of the development of hybrid technology. The report and submitted to the Qirui Research Institute.
Let him accidentally and touched that this report would like a stone sea in the sea, but the Chery executives, including Yin Tong, have quickly found him, not only certainly his thoughts, but also Decided to allocate nearly one million funds to him in the case of enterprise tightening trousers, and fully support him in-depth development of this strategic technology direction.
The exploration of Chery in the field of mixing technology has also attracted the attention of the Ministry of Science and Technology. In 2001, in the same year of the sedan production catalog, the Chery’s R & D team began participating in the 863 mixed automobile project hosted by the Ministry of Science and Technology.
Since then, as the first model is popular, it will not be stretched in Chery, which is no longer stretched in terms of funds, and let the R & D team actively participate in the domestic 863 mixed R & D projects. Engineers travel to overseas technology companies such as Ricardo, England, and quickly improve the development of hybrid technology.
In 2003, Chery’s “ISG Mixed Power Car” project was approved by the Ministry of Science and Technology as a “Eleventh Five-Year” 863 program second phase scroll project.
In 2007, Chery took the lead in completing the downline of ISG and BSG hybrid vehicle, and puts its mass production and put into operation.
In 2008, Chery Automobile delivered 50 to the Ministry of Science and Technology and Beijing, which was used in transportation services during the Olympics. This model was also officially pushed to the market in 2009, and became the only domestic only. One by one is mixed in 80,000 yuan.
In 2016, Chery launched an Ai Ru Phev model based on CVT transmission.
So, Chery is not a “one night” to take such an advanced DHT hybrid system, but has been carrying the R & D accumulation of mixing technology in the past 20 years.
Chery obviously very clear from the beginning,Motivation technology has long arrived in the second half or even the overtime, new energy and hybrids are the future of the automotive industry, but Chery is more clear: engage in research and development without shortcuts.
For the weak China Auto Industry, if you don’t go to the technology of the engine, you don’t know how to understand the underlying operational rules of the internal combustion engine, facing more complex hybrid systems, no distinctiveness, so-called “Curved overtaking”, if it is not based on the solid independent research and development, it will inevitably only choose the nose of the nose, relying on foreign suppliers, and finally may not overtake, but turned into the car.
In turn, putting the basic technologies in the fuel tragic field, it will be more likely to raise an anti-three in the technical field of electric vehicles, mixed power, such as hybrid vehicles to achieve the optimal fuel consumption level. It is not allowed to open a high level of fuel engine support. 
This is like the martial arts novel, Zhang Wuji first realized the martial arts of “Jiuyang Zhenjing”, thus laid for him later to learn other martial arts The solid foundation, eventually fusing, and one pass hundred, the world is invincible.
This is also the way Chery’s “training” – the previous use of the main energy to overcome the core technology of fuel car, while the R & D level furnace is pure, especially the research and development system and talent team After the ten veins, Chery has begun to accelerate the use of “new four” technologies such as the layout of electricization, intelligence, etc., whether it is revolutionary full-aluminum lightweight platform, autonomous controllable lion automatic driving, still “world” The first “DHT mixed architecture is the same.
In the words of Yin Yue, Chery is going to do, it is in technology “top-level” – in “new four” forward-looking technology “Top”, “landing” in traditional core technology.
From this point of view, Chery chooses to go offline its first DHT on May 18, and what you want to express is not And Yu – in the field of mixing research and development, Chery is still a boy who dares to want to dare. It has not changed.
And after the model of Qirui DHT is listed, we may expect Chery to lead China Automotive Industry to achieve new breakthroughs in the field of mixing technology, truly in the world and Toyota Honda The strength of the PK of the manufacturer.
