Can traditional car companies stand at the forefront of intelligence and electrification?
At GAC Science and Technology Day, a series of latest achievements were released:
- No picture, pure visual intelligent driving
- All-solid-state batteries
- Flying cars
- Electric wheelchair dual-purpose seat
There is both a consideration of the present and a bet on the future.
At the moment, GAC is under a lot of pressure:
The joint venture brand was impacted, the net profit was almost halved, and the profitability returned to 8 years ago.
To meet the challenges and face the future, GAC showed its technology card.
As a result, we have seen that the latest achievements of GAC's transformation are also examples of the transformation of traditional car companies.
GAC has no picture of pure visual intelligent driving
GAC mainly introduced two major technical achievements on the Science and Technology Day, first of all, let's look at the most noteworthy bracket intelligent driving:
GAC's mapless pure visual intelligent driving system removes lidar and does not rely on high-precision maps, and only uses visual solutions to realize full-scene intelligent driving, including urban NOA.
It can identify the respective status, symbol and countdown of the signal light, and the perception range is more than 150 meters in front of the car and 100 meters behind the car.
Narrow and three-dimensional parking spaces can also be used when parking:
This set of intelligent driving algorithms also supports self-improvement in the simulation system, for which GAC has developed its own data closed-loop and simulation system, and launched the GAC cloud data center and intelligent driving simulation platform, with data as the core, driving the iterative upgrade of AI algorithms.
The pure visual intelligent driving solution without pictures is not all of GAC's intelligent driving technical reserves.
There is a "fusion perception" scheme of lidar, and GAC also has a layout.
Goal: Both routes can achieve "high-precision map" and "open with navigation".
It sounds like "the whole country can be opened" in another way.
The phrase "the whole country can be opened" is the same as the far ahead, and the Slogan, which was brought to fire by Yu Chengdong last year, was first landed by Huawei, so that the new force "Kaesong War" died down overnight.
At this time, some traditional car companies stood up and said that they wanted to go to high-precision maps and "can drive if they have navigation", showing courage and confidence.
Where is GAC's confidence?
In fact, although it is a traditional car company, GAC has good technical reserves in intelligent driving.
Previously, he showed off a L3 intelligent driving that took off his hands and eyes, and in the morning rush hour, he crossed the highway and urban areas.
Recently, it also joined hands with Didi, and the two sides jointly established a joint venture autonomous driving company Guangzhou Andi, each holding a 50% stake, to promote the mass production of Robotaxi and mass production next year.
Therefore, at present, GAC has laid out two major technical routes of L2 high-end intelligent driving, actively promoted the implementation of L3, and also planned L4 production car projects.
The emphasis on intelligent driving is rare among traditional car companies.
GAC has made progress in intelligence, and electrification has also ushered in a breakthrough.
Without playing word games, the real all-solid-state battery also appeared on GAC Technology Day.
GAC all-solid-state power battery
The so-called all-solid-state battery, that is, does not contain liquid electrolyte and relies entirely on solid-state energy storage, which greatly improves stability and energy density.
At present, the solid-state batteries that have been put on the car in China are semi-solid-state batteries in the strict sense, such as the Zhiji L6 that was just launched at the beginning of this month, and the "solid-state battery" is from Qingtao New Energy, a Tsinghua entrepreneurial project, which still contains more than 5% liquid electrolyte.
GAC's all-solid-state battery goes a step further by removing the liquid electrolyte, although it will not be installed until 2026.
The energy density is over 400Wh/kg, which is more than 50% higher than the industry's leading liquid lithium-ion battery, and the vehicle mileage can exceed 1000km after getting on the car.
According to GAC, the battery has been tested under extreme conditions such as acupuncture, cutting, -78°C dry ice environment and 90°C hot water immersion, and the performance has remained stable.
And there was no thermal runaway in both nailing and cutting.
According to reports, the first launch will be carried on the high-end brand Haobo model of GAC.
In addition to the two core technological achievements, GAC introduced other progress:
In March this year, GAC's first flying car, GOVE, was flight verified over the CBD of Guangzhou.
Launched the Trumpchi E9 welfare version, the electric seat on the car, which can be used as an electric wheelchair when getting out of the car, with a cruising range of 26 kilometers and a maximum load of 120 kg.
Through the GAC Technology Day, it can be found that GAC has tried a new path among traditional car companies:
Although it is also the same as other car companies, it is improving the content of China, such as the recent launch of the Trumpchi M8 Hongmeng cockpit version.
However, it is more of an independent exploration, and it has made concerted efforts in electrification and intelligence, and has a layout for L2, L3, and L4 intelligent driving, and has mastered the production of power batteries, the core components.
This provides a reference and demonstration for other traditional car companies that are also facing shocks and sharp declines in profits.
