　　On September 24th, the highly anticipated HarmonyOS Zhixing Zhijie R7 coupe SUV was officially unveiled at the 2024 Huawei Autumn New Product Launch Conference. This luxury SUV, which integrates Huawei’s cutting-edge technology, has attracted the attention of many consumers with the strong blessing of Huawei’s Gankun Zhijia and the pre-sale price of 268,000 yuan.

　　Yu Chengdong, Chairman of Huawei BG and Chairman of BU, a smart car solution, said that in the intellectual world R7, HUAWEIADS 3.0 advanced intelligent driving system will be put on the bus, which adopts a revolutionary end-to-end architecture to upgrade intelligent driving, intelligent parking and active safety.

　　It is worth mentioning that for Shenzhen Yinwang Intelligent Technology Co., Ltd., which was previously registered by Huawei, a few days ago, Xu Zhijun, the rotating chairman of Huawei, responded to industry concerns for the first time. "At present, it is still in the first stage. When the second batch of car companies will come in, there is no clear plan, but they are in contact with all car companies."

　　HarmonyOS Zhixing released the first smart SUV model.

　　At the press conference, Yu Chengdong said that as of September 9th, the number of reservations for Huawei’s M9 had exceeded 140,000 units, while that for Zhijie R7 had exceeded 30,000 units in less than two weeks. This data not only shows the strong performance of Huawei smart cars in the market, but also reflects consumers’ high recognition and expectation of Huawei brand and its smart car products.

　　At the press conference of Zhijie R7, Yin Tongyue, Party Secretary and Chairman of Chery Holding Group Co., Ltd. said that Zhijie, as the first priority strategic project of Chery, has a research and development team of more than 1,000 people and has invested 10 billion yuan.

　　It can be seen that under the deep accumulation in the field of ICT, Huawei and domestic car companies are constantly drawing new blueprints for smart electric vehicles and smart driving. HarmonyOS Zhixing, as the core driving force of this strategy, is empowering the whole automobile industry with unprecedented depth and breadth, and pushing it to a higher level of industrial upgrading.

　　"With the blessing of Huawei’s Gankun Zhijia, the vehicle can not only cope with complex road conditions independently, but also show accuracy when parking." Yu Chengdong said that as a pure electric SUV, Zhijie R7 is equipped with Huawei Whale 800V high-voltage battery platform, with 800V high-voltage fast charging, 802km long battery life and more than 80,000 cooperative charging networks. The Max version and Ultra version of Zhijie will start mass delivery on October 15th, and the Pro version will start mass delivery on November 15th.

　　According to the official data released by HarmonyOS Zhixing, in August this year, HarmonyOS Zhixing delivered 33,699 new cars, including 31,216 new cars delivered by Wenjie, and the remaining 2,483 vehicles were delivered by Enjoying S9 and Zhijie S9, but the official delivery volume of specific models has not been announced yet.

　　It is expected that Huawei BU independence will be completed by the end of this year.

　　While HarmonyOS Zhixing continues to expand its product lineup, Huawei BU is also seeking a more independent operation mode and a broader technical cooperation prospect. Since Huawei Car BU formally established Shenzhen Yinwang Intelligent Technology Co., Ltd., a subsidiary of smart cars (with Yinwang) at the beginning of this year, all kinds of speculations in the industry around Yinwang have remained high. Especially in recent years, Aouita and () have successively taken shares, which makes Yinwang become the focus of public opinion.

　　In this regard, Xu Zhijun, the rotating chairman of Huawei, said that the company is still in the first stage, and started to operate as an independent company, and also introduced the investment from the first two car companies, including Aouita and Cyrus. In its view, in terms of automobile business, Huawei has clearly focused on three intelligences: intelligent driving, intelligent cockpit and intelligent vehicle control, which is precisely the field where Huawei has superior technology and capabilities and can reflect market value.

　　"At the end of this year, I hope to finish the first step and load all assets and personnel into the hope. When the second batch of car companies will come in, there is no clear plan. But we are in contact with all car companies. " Xu Zhijun said that Yinwang is reconstructing the cooperative relationship between automakers and component suppliers, and is also reconstructing the business model, from the original simple trading relationship to a value-sharing relationship.

　　Hope not only operates independently, but also receives long-term support from Huawei. The new company will continue to use two core brands-Gankun Zhijia and HarmonyOS Cockpit, and lead the intelligent second half of the automobile industry together with its partners.

　　Xu Zhijun believes that the change of this relationship is mainly reflected in two aspects. On the one hand, the product chain and value chain have been extended and upgraded in enterprise innovation; On the other hand, as an independent company with diversified equity, Yinwang is deeply bound to the automobile factory as a community sharing interests and risks.

　　When asked whether Huawei will insist on holding shares? Xu Zhijun said that without this idea, Huawei hopes that the more friends, the better. "At present, Huawei BU has a research and development team of more than 7,000 people, and has invested more than 40 billion yuan in research and development." Xu Zhijun revealed that in the most difficult period, the annual loss was more than 8 billion yuan. However, after hard work, a number of strategic cooperation models have been listed.

　　"Whether it is BU or Hope, it has passed the most difficult period. It has achieved profitability in the first half of this year and is expected to achieve full-year profitability." Talking about the future and challenges of Yinwang, Xu Zhijun said that the investors introduced by Yinwang must be strategic investors, not financial investors. Hope to closely combine with partners to realize risk sharing and benefit sharing. In operation, Yinwang will also abide by the independent business model and trading model and treat all customers equally.

　　[Gearbox Technology] With the increasing publicity of major car companies in recent years, dual gearboxes are rapidly being accepted by ordinary consumers. The rapid and large-scale popularization has also fully exposed its shortcomings, especially the low-speed frustration, abnormal noise and poor stability of some gearboxes. So, the problem can’t be avoided?

　　Even if you are not the owner, it seems that you can easily tell the shortcomings mentioned above when you mention the dual-clutch gearbox, especially the dry dual-clutch gearbox. After everyone has experienced its extremely fast shift speed advantage, it is not difficult that it also has obvious shortcomings. To get the answers to these questions, we must first talk about the basics.

■ What is the gearbox thinking?

　　For me, the gearbox can be said to be the best partner. The characteristics of low speed, low speed and high torque are revived by the gearbox, which can make the engine release high torque in the low speed range and low torque in the high speed range, so as to meet the different needs of vehicle climbing, traction or fuel economy. All this is the credit of gearbox gear selection, so why does it shift gears?

　　When the vehicle is running, the gearbox computer will judge the state of the vehicle through the data transmitted by various sensors, and then it will operate. This process is actually quite similar to our human thinking about life in a daze. Put yourself in the position of thinking about the problems and personal status, and then give solutions, and then the process of practice is exactly the same as that of human beings. This is just a series of actions on the gearbox, which are completed in milliseconds.

■ Can the problems of frustration and abnormal sound be avoided?

　　The development engineer is the person who has the most say in all kinds of situations of dual-clutch gearbox and the methods and means to solve the defects. As it happens, the editorial department just bought a new 7-speed dry-type one, so we consulted its engineer in charge of the development of dual-clutch gearbox on related issues.

■ Not only software, but also hardware optimization can reduce frustration.

　　From the problems we have collected, it seems that some dry dual-clutch gearboxes have been criticized by many people for shifting at low speed, so where does this feeling come from? Can it be effectively changed only by adjusting the software control strategy?

　　In fact, there is a similar semi-linkage state in the power transmission process of dual-clutch gearbox, in order to reduce the wear of clutch plates. Therefore, the engineer will combine the clutch pressure plate with the friction plate as soon as possible. At this time, if the difference between the output speed of the engine and the output speed of the transmission is relatively large, there will also be setbacks.

　　The previous 7-speed dry dual-clutch gearbox with code DQ200 used mechanical control arm and sleeve to squeeze diaphragm deformation. From the structural point of view, its transmission efficiency is higher. After being optimized for hydraulic system, it can better filter vibration, thus further reducing the occurrence of frustration.

　　In addition, when it comes to low-speed gear shifting, some friends may feel that the performance of the gearbox is slightly different in the same speed range after the "cold car" state and the "hot car". This phenomenon actually does not only appear in the dual-clutch gearbox, but also exists in AT, etc.

　　In addition to the optimization of these gearboxes mentioned above, the ride comfort of vehicles is actually related to the engine. Its torque response speed is also one of the factors that influence driving experience. At the same time, the powertrain mounting design also affects the driver’s perceived ride comfort to some extent. Therefore, it can be said that the optimization of powertrain ride comfort is a far more complicated project than imagined.

■ Where does the abnormal sound come from?

　　The sound generated during the operation of the gearbox, or those unpleasant abnormal noises, will drive the user crazy more than frustration, so where is the source of the abnormal noise? How to optimize it?

■ Poor stability of dry dual clutch?

　　When it comes to dry dual-clutch gearbox, poor stability or prone to thermal protection is also a problem that people give more feedback. Compared with the natural "weakness" of gearbox structure, how do engineers solve this part of the problem in the development process?

　　In the testing process, the development team conducted a longer related test for congested road conditions, and simulated the extreme conditions that car owners would encounter in their daily driving on roads with severe congestion and long creep. Finally, through the improvement of clutch plate material and control strategy, the gearbox assembly reaches the design goal of 320 thousand km maintenance-free

Full text summary:

　　At present, in the domestic market, consumers often regard whether to use the dual-clutch gearbox as the standard to judge the technical maturity of a car. However, compared with the wet dual-clutch, the dry dual-clutch gearbox is more prone to overheating in the face of urban congestion and creeping road conditions because its clutch assembly has no oil to dissipate heat. The structural differences make it at a disadvantage in terms of stability. In addition, in the process of its work, the sound generated by the fork and clutch plate also affects the use experience to a certain extent. From the engineer’s point of view, the problem can be solved to some extent by software control strategy. In addition, some problems can be solved at the hardware level by using hydraulic control system and replacing clutch plate materials. (Text/Figure car home Tang Dynasty)

At the Guangzhou Auto Show, which opened on November 15, Porsche unveiled a number of models, including the new 911 Targa 4 GTS, the 911 Turbo 50th Anniversary Edition, the new pure electric long-range version, the new 4, the new Panamer, and the 718 Boxster Style Edition.

The following is a detailed account of the most interesting models for everyone.

The most eye-catching product at the auto show – the new 911 Targa 4 GTS

In today’s era of new energy, the new 911 GTS is also powered by electricity, but electricity is only part of the performance enhancement. In the 911 GTS model, it does not participate in pure electric drive. The new 911 Carrera GTS model, which is also equipped with the T-Hybrid system, ran a lap time of 7 minutes 16.934 seconds on the Nürburgring North Circuit, 8.7 seconds faster than the previous generation model.

The T-Hybrid high-performance hybrid system on the 911 Targa 4 GTS is equipped with an electric exhaust gas turbocharger, an integrated motor located between the compressor and the turbine, which can instantly increase the speed of the turbocharger for instant charging.

This motor in the turbocharger can also be used as a generator. It draws energy from the exhaust stream to generate up to 11 kW (15 PS) of electricity. The powertrain also includes a permanent magnet synchronous motor integrated in the PDK 8-speed dual-clutch transmission.

Even at idle, the motor can assist the horizontally opposed engine to provide up to 150 Nm of additional drive torque, resulting in a system power boost of up to 40 kW.

Porsche connects two electric motors to a compact, lightweight, high-voltage battery that, while comparable in size and weight to a conventional 12 V starter battery, can store up to 1.9 kWh of energy (total energy) and operate at up to 400 V. In this way, with the newly developed 3.6-liter horizontally opposed engine, the system can achieve a total power of 398 kW (541 PS) and a maximum torque of 610 Nm. Equipped with a ChronSport ejection assembly, it can accelerate for 3.1 seconds per 100 kilometers.

In terms of appearance, the 911 GTS is more modern and concise, with an emphasis on aerodynamic performance.

Tribute to Yourself – Porsche 911 Turbo 50th Anniversary Edition

Porsche’s first 911 Turbo model was born in 1974. To celebrate the 50th anniversary of the 911 Turbo, Porsche launched the 911 Turbo 50th Anniversary model. Porsche built the 911 Turbo 50th Anniversary model based on the previous generation 911 Turbo S, and selected Heritage Design components, which were limited to 1,974 units worldwide.

The new energy is a major trend, and Porsche, as a sports benchmark, has also brought two forward-looking products in the field of electrification – the new pure electric Macan long-range version and the new Taycan 4, the new Taycan is specially tailored for the Chinese market.

Pure electricity does not reduce the fun of sports

The new pure electric Macan is based on the pure electric 800V platform from PPE, and the new pure electric Macan long-range model has design, sports, energy efficiency and other characteristics.

In terms of three power, it is equipped with a 100 kWh power battery. With a maximum kinetic energy recovery power of 200 kW and a wind resistance coefficient as low as 0.25, the new pure electric Macan long-life version has a comprehensive operating mileage of 702 km (CLTC). Thanks to the advantage of 800V, the charging power of the pure electric Macan long-life version can reach 270 kW, and the battery life can be increased by 260 km after 10 minutes of charging.

Another model, the Taycan 4, is a model exclusive to the Chinese market. While maintaining long range and charging speed, it can also output super power. The Taycan 4 comes standard with a 105 kWh high-performance battery with an output power of 380 kW (517 PS) and a 100-kilometer acceleration of 3.9 seconds.

And equipped with adaptive air suspension, Porsche Sport Chrono ejection, components, BOSE^? Surround sound system and other configurations.

At the same time, two models that focus on comfort – the new third generation and the new Cayenne – also landed at the Guangzhou Auto Show, among which the Panamera models are equipped with Porsche Active Ride, etc., while providing higher comfort and Porsche’s signature driving pleasure.

Summary: The trend of new energy is very strong. Porsche has introduced two pure electric high-performance products to the Chinese market, as well as the 911 Targa 4 GTS and 911 Turbo 50th anniversary models, as well as models such as the 911 Carrera T that make high-performance more entry-level. The fuel and electric track will be developed simultaneously. You can look forward to it.
