In the current automobile market, hybrid power is no longer a new topic. In the distance, there are "Shuangtian" i-MMD and TNGA competing, and recently there are "independent" DM-i, Thor Hi· X. Lemon DHT and Kunpeng DHT are in full bloom. Among them, Chery's full-featured hybrid configuration Kunpeng DHT, which was launched for the first time at this year's Shanghai Auto Show, is different from the common hybrid technology on the market. It has 3 physical gears, 9 working modes, and realizes 11 gear combinations. It can be said that the Kunpeng DHT super hybrid is the most sophisticated hybrid technology currently on the market. Today, we will explain Kunpeng DHT in detail to see what its strength is.
Different from the mainstream trend, Kunpeng DHT is more forward-looking
Before talking about "3 gears, 9 modes and 11 speeds", you first need to understand what Kunpeng DHT is and its work The principle can be better understood. Chery's Kunpeng DHT is defined as "Dedicated Hybrid Transmission", which means hybrid special transmission. It achieves a high degree of integration of motor controller, dual motors and transmission.
It is not difficult to find from the recent market trends that more and more products are equipped with dual motors, which has become the mainstream development trend of the industry. Although dual-motor products have begun to increase, most of them still use a single motor + engine as the main driving method. To put it simply, one motor works and the other rests, changing back and forth. However, Kunpeng DHT has a hybrid architecture that can achieve dual motor drive.
In the Kunpeng DHT architecture, the motor plays a major role. The dual motors can be driven individually or simultaneously, with better performance and stronger explosive power. The engine can be timely intervened according to user needs according to actual road conditions. , which also means that Kunpeng DHT can bring users a "quick start and sufficient power" driving experience.
“3 gears, 9 modes and 11 speeds” is more suitable for user scenarios
Speaking of this, I believe you have a preliminary understanding of Kunpeng DHT, which is derived from it It adopts dual motor and engine drive mode, so it is equipped with a 3-speed transmission device. You must know that most of the current mainstream technologies use direct clutch structures, that is, generators directly drive the wheels. Such products only have one gear, which is what we often call "single-speed" products.
Single-speed products naturally limit the vehicle's most efficient working range, while Kunpeng DHT's three gears can broaden the engine's driving performance, just like the difference between ordinary bicycles and variable-speed bicycles. The gear shifting logic of Kunpeng DHT is the same as that of a fuel vehicle. The first gear is mainly used for starting or driving at low speed; the second gear serves as a link between the previous and the next, ensuring the smoothness of the gear shift, whether from low speed to medium speed, or from medium speed to high speed. It also takes into account the fuel consumption level; the 3rd gear can keep the vehicle speed and fuel consumption at a lower level when driving at high speeds, which is more in line with the user's daily driving habits.
In order to cope with many different road conditions, Kunpeng DHT matches the vehicle to achieve single/dual motor drive, extended range, parallel connection, engine direct drive, single/double motor braking energy recovery, driving/parking 9 high-efficiency working modes including charging. For example, if you are stuck in a traffic jam at work, you can use a single motor to drive the vehicle, which can effectively reduce travel costs; if the road is good, you can let the two motors drive simultaneously to make the car more powerful; if you are driving at high speed, you can let the motor rest and the car will be more powerful. The engine's direct drive ensures low fuel consumption while providing stronger power, and can recycle excess energy to charge the motor.
In addition, there are dozens of permutations and combinations of 3 physical gears and 9 working modes, but Chery has chosen the 11 most commonly used combination gears, covering starting, medium and low speed, 11 driving scenarios including elevated, overtaking, red light, congestion, highway, long-distance, mountain road, high-speed steering, ice and snow/mud/sand and gravel. It is worth mentioning that Kunpeng DHT can calculate the optimal working mode in real time based on the road, eliminating the need for users to manually switch, ensuring efficient power output at all times.
The "paranoia" of science and engineering men, craftsmanship and reliable quality
Some people may have worries that the more sophisticated the product, the easier it is to break, and that a mistake in a small link may lead to an overall collapse. . In fact, there is no need for it. As a technical man in science and engineering, Chery has always been known as a "quality maniac" in the industry. Kunpeng DHT has more than 20 years of experience in the research and development of hybrid technology. It has gone through the rigorous testing process of 30,000 hours of bench verification and 5 million kilometers of vehicle verification, making it a safe choice for users with reliable quality.
With the arrival of Tiggo 8 PLUS Kunpeng e+, the first equipped with Kunpeng's DHT super hybrid technology, not only will the Tiggo 8 series product matrix be further enriched, but Chery's green path will also be taken a step further.
