Jiefa Technology Ma Weihua: Aiming at the mainstream automotive consumer market to create an integrated solution for smart cockpits

Editor's note: On June 7, 2022, the 2022 Automotive Chip Industry Development-Cloud Forum hosted by Gasgoo was held as scheduled.Ma Weihua, deputy general manager of Jiefa Technology and general manager of Shanghai Tuqingwei, was invited to attend and delivered a keynote speech on "Aiming at the mainstream consumer market of automobiles and creating an integrated solution for intelligent cockpits".Gasgoo has compiled a text based on the speech to share with readers.

It can be found from the global market that from 2007 to 2021, the overall sales of passenger cars in the world increased from a peak of about 94 million in 2018. Later, due to the epidemic, this number will be 78 million in 2020 and 81 million in 2021. .

At the same time, the state has introduced purchase tax incentive policies, including Shanghai, Shenzhen and other places have also introduced corresponding incentive policies. It is expected that the purchase tax reduction and exemption incentive policies will bring an increase of more than 1 million passenger cars to domestic passenger cars. , which can effectively make up for the decline in passenger car sales in April and May this year.Therefore, Jefac believes that although the domestic passenger car market fluctuates, it is still improving.

Converged smart cockpit is the general trend

Jiefa Technology has sorted out the top 15 popular models in 2021: Dongfeng Nissan Sylphy ranks first, with a single-year sales of 470,000 units, the second is Wuling Hongguang MINIEV, with a sales volume of 410,000 units, Volkswagen Lavida 380,000 units, followed by Harvard H6, Toyota Corolla, etc.

The cockpit includes the instrument and the central control. Jefak divides the central control except the instrument into IVI, FM and DA. What cockpit shape do the 15 popular models use?According to Jiefa statistics, Nissan Sylphy uses IVI, which is entertainment multimedia, including navigation, real-time road conditions, vehicle control, mobile office and other ecology.FM only has radio, no screen.DA has a large screen and has the basic functions of mobile phone interconnection.

Nissan Sylphy uses IVI+ combination instrument, Wuling Hongguang is FM, that is, radio + full LCD instrument, Lavida uses DA + combination LCD instrument.Except for the two lines I marked with green marks, except for Tesla Model Y and Great Wall Haval H6, the other 13 models have LCD instrumentation and central control separated, and these two product forms are not well integrated.

Tesla's Model Y and Great Wall Haval H6 have adopted smart cockpits, realizing the close integration of instrumentation and central control.Therefore, a new concept was born - the smart cockpit.

The so-called smart cockpit must first realize the integration of the instrument and the central control, which is a necessary condition. It can be displayed on multiple screens, or the instrument and the central control can be fully integrated.In addition, there will be requirements for informatization, entertainment, and interactive functions, which are the basic functional requirements of entry-level smart cockpits. More intelligent are the functions of perception and driver interaction, which are also flagship smart cockpits.The integrated smart cockpit must be the future development trend.

There are two main reasons for the separation of the current instrumentation and central control: first, the overall cost of the smart cockpit is relatively high; secondly, the smart cockpit currently has a single function, and the smart cockpit is now more distributed in flagship models and high-end models. It is difficult to import low-end models. .

At present, the diversity of the overall solution of the smart cockpit is insufficient, and the choice of models is limited.A single IVI+ LCD instrument and a DA+ LCD instrument all need to be matched with the corresponding smart cockpit.Only a variety of smart cockpits can increase the penetration rate and matching rate of model smart cockpits.

Ma Weihua said that the current smart cockpit coverage rate is 10%-20%, and it will develop to 40%-50% in the future, and the incremental market is very large.In the development process, the smart cockpit solutions on the market should be diversified to provide users with rich choices.

Jiefa Technology's smart cockpit series chips can meet diverse market needs

The vehicle layout of Jefaco automotive chips is divided into the following categories:

One is the solution of the smart cockpit chip; the second is the solution of the car networking chip; the third is the central control entertainment navigation.

In the chip and platform solutions of the smart cockpit, in order to meet the diversified needs of the market, Jiefa Technology has two chip series and three part numbers respectively.These three categories are: entry-level cockpit, mid-level smart cockpit and mid-to-high-end smart cockpit, corresponding to AC8015I, AC8025E and AC8025H respectively.

For the above three products, in terms of function, Jiefa Technology defines the entry-level cockpit as a 2.5D LCD instrument + DA, and optional 360-degree surround view function. The function is relatively simple, but the integration is very high.

The AC8015I chip has been mass-produced in early 2021 and has now been shipped in large quantities.The main feature of this chip is a relatively high level of integration, with a 6-core CPU, a 4-core A53+2-core R5F, a GPU of 30 GFLOPS, an integrated HSM hardware encryption module, an independent security island, and rich interfaces.AC8015 can meet the product types and market demands of entry-level cockpits.The second product is AC8025E, which will be launched at the end of this year. Compared with 8015I, the biggest feature of 8025E is to improve CPU performance. The CPU is 6-core A55+2-core R5F, the computing power reaches 30KDMIPS, and the GPU reaches 60 GFLOPS.

The third higher-end product is the 8025H, which is positioned as a mid-to-high-end smart cockpit.The 8025H has two A76 large cores + six A55 small cores, the computing power is around 60KDMIPS, the GPU is 120GFLOPS, and it also has NPU, HSM and Audio DSP.Two part numbers of AC8025 are capable of supporting functional safety and meeting ASIL-B requirements.The mid-to-high-end smart cockpit 8025H has 3D LCD instrumentation + IVI central control + co-pilot screen + air conditioning screen, and supports up to 6 screens.It can realize the overall solution of middle and high-end intelligent cockpit.

The above two chip series and three part numbers are smart cockpit solutions launched by Jiefa Technology in the market under the background of increasing penetration rate of smart cockpits, in order to meet the diversified needs of smart cockpits in the market.

In the middle of the instrument screen is the central control IVI. Users can put the navigation and entertainment of the central control in the middle of the instrument to realize the integration of the two products.This is the advantage of the integrated cockpit solution, because the system is the same chip, and the integration and interaction within the chip will be easier.

The characteristics of the entry-level cockpit solution can be summarized as 1+1+1, 1 is the 2.5D LCD instrument, which is a product form; the second is the central control large-screen IVI; the third is the AVM box, which can achieve this. Three product forms three in one function.Among them, Jiefa's own software solutions, including its own algorithms and built-in DSP sound effects, Bluetooth, and the interactive SDK of the instrument central control, will be provided by Jiefa.

Jiefa Technology's integrated smart cockpit solution is a hardcover room that includes applications, systems and hardware. The

entry-level cockpit can achieve 2D or 2.5D UI, as well as the display of warning sounds, chart information and driving information.The interaction with the central control can realize FM, sound, control information return and so on.

The IVI central control can realize Bluetooth, Wifi, multimedia, FM, fast reversing, surround view, etc. The mobile phone interconnection is also relatively complete, and it also supports third-party applications, online music, etc.

The 8015 entry-level smart cockpit solution is a very complete solution, which covers three aspects: application, system and reference hardware. The application refers to the algorithm, mobile phone interconnection, sound effect, etc. provided by Jiefa Technology, which will provide design support. refer to.

The system side includes supporting operating systems such as Linux, Android Automotive, AGL, AliOS, etc. Jiefa Technology has iterated from Android 4.0 to now 11.0, most of which are iterations of Jiefa Technology’s self-developed systems from generation to generation. This part of the experience is very Rich.

In terms of hardware, Jiefa Technology provides a complete reference solution.

Jiefa Technology's integrated smart cockpit solution is equivalent to providing a hardcover room for check-in. Users only need to do some customized development to achieve a relatively mature and stable chip platform state.

The characteristics of the overall solution can be described in three words: fast, good and economical.

Fast: Users can quickly develop on the overall solution provided by Jiefa Technology.In the past, there were many cases of Jiefa Technology. Customers were developing on the new platform. From the beginning to the end, they could develop to a state close to mass production within half a year.

Good: The system provided by the chip manufacturer will be more stable.The hardware reference system of Jiefa Technology has been optimized on the periphery.

Savings: Based on the above complete solutions, stable systems, and optimized hardware, customers can use Jiefa's solutions with great peace of mind and achieve the purpose of fast, good and economical.

The high level

First, in its DSP, there are two built-in DSPs, which can save the external ADSP chip and optimize the overall cost.Jiefa Technology provides volume management and control of its own sound effects based on two DSPs, including mixing, and can also provide algorithms that meet certification.The entire channel is very rich, and there are two dual-channel microphone outputs, which can be experienced.

The second feature is that it can support a complete set of solutions for wired and wireless Carplay. From the application layer, the system layer to the bottom layer, it will provide a complete set of APPs, including middleware, including SDK, and Jiefa Technology will also maintain it.

The third feature is Jiefa Technology's own 360 surround view algorithm, which can be provided to customers.The 360 ​​Surround View algorithm has been verified by customers in mass production, and it can support 3D views, personalized design of car models, etc.These features determine that the integration of the entry cockpit is very high.

Jiefa Technology's mid-to-high-end smart cockpit chip AC8025 is highly reusable and

AC8025 is positioned as a mid-to-high-end smart cockpit. The chip architecture is very close to AC8015, and the overall architecture is relatively consistent.The reusability of the systems and codes of these two chips can be as high as 75%-80%. The development of the two chip platforms is relatively easy to transplant, and the work done on the AC8015 can be easily transplanted to the AC8025.

What upgrades have AC8025 made compared to AC8015?The CPU has been upgraded from the original 4-core A53 to 8-core (2 A76+6 A55), and the NPU is also integrated. At the same time, the AC8025 can support the functional safety ASIL-B of the LCD instrument.

The development history of Jiefa Technology

Judging from the shipments of central control SoCs, it is preliminarily estimated that more than 500 models around the world are using Jiefaco's SoC chips, and a total of nearly 70 million sets of SoC chips have been shipped, exceeding 200 million, which is equivalent to nearly 70 million vehicles equipped with Jiefa. The SoC of the central control of the technology.

Ma Weihua's speech provided more directions and possibilities for the development of intelligent cockpits under the wave of automotive intelligence, and also provided more thinking space for partners who are concerned about the development of China's automotive chip industry.China's automotive chip industry needs the cooperation and mutual assistance of the upstream and downstream industry chains to develop together.In the future, Jiefa Technology will join hands with its partners to build a leading brand of domestic automotive electronic chips and achieve a greater breakthrough in "Chinese chips".
