On February 30th, 65438, Great Wall Motor offered another "killer". Following the release of the coffee intelligent platform in July, the Great Wall intelligent travel solution-coffee intelligent driver was officially released. Along with this technology, there is also the "33 1" strategy of coffee intelligent driving.

According to Great Wall Motor's plan, after three years, their goal is to be based on the China market and become the leader of autonomous driving in the intelligent era in the industry, so as to achieve "the largest scale of users in the industry, the best evaluation of user experience and the most coverage of scene functions".

At the moment when intelligence has long been the development trend of the automobile industry, facing the impact of Internet companies, even technology giants such as Apple, and facing the new forces that have always taken intelligence as their core selling point, the outside world can't help but wonder where the Great Wall, as a traditional automobile enterprise, came from.

Six redundant designs, the technical strength of the Great Wall

At the press conference on the 30th, Great Wall spent a long time interpreting its six redundant designs in the intelligent driving of coffee after releasing the "33 1" strategy. And these technologies are the first strength of the Great Wall.

Specifically, these six redundant systems are sensor redundancy, controller redundancy, braking redundancy, architecture redundancy, power supply redundancy and steering redundancy.

For consumers, the most important attribute of intelligent driving system is safety on the basis of convenience and intelligence. The original intention of Great Wall Motor's six redundancy designs is to ensure safety, and to ensure safety by improving intelligence.

To realize intelligent driving of vehicles, we must first "see the road clearly". The so-called "perceptual redundancy" is aimed at this step.

According to reports, unlike the traditional millimeter-wave radar system, Coffee Smart Drive is equipped with the world's first all-solid-state laser radar system with the highest resolution, which can sense lane lines, pedestrians, vehicles and even tiny objects of 20cm.

The world's first truly mass-produced automobile-grade high-performance all-solid-state lidar is used for intelligent driving of coffee.

In addition to "seeing the road clearly", the intelligent driving system also has a set of controller equivalent to the brain, which manages, calculates and controls various functions on the vehicle.

On the controller, the intelligent coffee driver adopts a dual-controller architecture. If there is a problem with one architecture, it will switch to another architecture within 0.02 seconds, which is equivalent to having two "brains".

Moreover, this "brain" is also very smart and responsive.

According to reports, in the production car of 202 1, the chip used by the Great Wall is Huawei Shengteng 6 10, which is the most powerful self-driving chip in mass production at present. By 2022, it will be equipped with a more powerful SA 9000B from Qualcomm.

Similar to the above ideas, several other redundant designs are the same.

For example:

Architecture redundancy means that the coffee intelligent drive has three independent all-physical communication architectures. Through 10 software logic analysis, the controller path is clearer and clearer. Moreover, in terms of architecture redundancy, information between more than 30 sensors can be transmitted and shared transparently.

Power redundancy means that the Coffee Smart Drive is also designed with a dual power supply configuration, and the system can continue to run for 5 minutes even after the main power supply fails. At the same time, through the double isolation scheme, the system can also block all driving risks within 500us.

Braking redundancy, the vehicle can be braked redundantly by ESP+iBooster in the full speed range of 0- 120km/h, and the maximum braking of-100 m/s can be realized. The system is equipped with HAD 1 main control unit and HAD2 main standby control unit, which can be controlled by dual networks.

Steering redundancy, it is said that the technology of Great Wall is at least ahead of the industry 1 year, and it is the first fully redundant steering design in the world.

Through these six redundant systems, Coffee Smart Drive has achieved full scene coverage of high-speed and urban expressways.

Intelligent driving function of Great Wall Motor and cart

Judging from the demonstration video at the press conference, coffee intelligent driving can help vehicles to avoid obstacles and change lanes, change lanes for multiple vehicles, and change lanes independently in cities. At the same time, breakthroughs have been made in difficult scenes such as cart walking and cone obstacle avoidance. These functions are rarely seen in the related introduction of auto-driving of car companies in the past.

The scale of a million-class car brings cost and speed advantages.

According to the plan of "33 1" strategy, the system will be put into mass production in 20021year.

It is said that the first model equipped with coffee intelligent driving will be unveiled next month and listed in the first quarter of next year, and this model is the flagship SUV of WEY brand that has been exposed before.

In addition, from the second half of next year, coffee smart driving will also be carried on other brands of Great Wall Motor.

Thanks to the huge scale and cost control ability of Great Wall Motor, according to Zhang Kai, the head of intelligent driving of Great Wall Motor, the prices of these models will not increase significantly.

At the same time, after mass production, by 2022, Great Wall Motor's goal is to become the largest intelligent driving computing platform in China with the largest number of assisted autonomous driving users and the first L4 intelligent driving capability in China.

By 2023, the goal of Great Wall Motor is to build an L4-class autopilot system covering the most scenes in China. The ultimate goal is to "let users enjoy a cup of coffee in self-driving cars".

According to Chen Xianling, the new digital executive of Great Wall Motor, it has been 10 years since it was announced in 2009 that it began to study autonomous driving technology.

After the accumulation of 10 years, the R&D department of Great Wall Motor's intelligent driving has developed from the initial three people to 500 people today. At the same time, relying on the sales of Great Wall Motor, they have also accumulated a wealth of user data.

It can be said that compared with the new forces of car-making and technology companies such as Apple, the greatest advantage of Great Wall as a traditional car company lies in its huge scale and deep insight into consumers after years of deep cultivation in the market.

In the words of Zhen Longbao, the intelligent driving director of Great Wall Motor, the core competitiveness of Great Wall "is ultra-low AI iteration cost and ultra-fast AI iteration speed. As one of the giants with a scale of one million vehicles, Great Wall Motor will gain great advantages in the long-distance running competition of data cost and iterative speed. "

Write it at the end

From mid-July this year, the Great Wall began to announce the transformation to a "global technology travel company" in the form of a micro-film and an internal letter, and the adjustment of this enterprise has never stopped for several months. Now, with the release of the "33 1" strategy, the transformation of the Great Wall has begun to enter a new stage.

The capital market has been optimistic about a series of adjustments made by Great Wall Motor since the second half of the year. By the close of February 30th, 65438, the share price of Great Wall Motor had risen from the low point of 7.9 yuan at the end of June to 37 18 yuan, and its market value had exceeded 340 billion yuan.

Judging from the current news, Great Wall Motor will still have a large number of products and technology reserves next year after the adjustment of "30 years old". In the future, with the landing of new technologies and the introduction of new products, it may not be an exaggeration to describe this enterprise as "the future can be expected".
