In terms of safety, GAC all-solid-state power battery adopts high-strength dense composite The electrolyte prevents the battery from exploding in a high-temperature environment of 200°C, and sets a new level of safety for high-specific-energy batteries. In addition, the battery has maintained stable performance under extreme conditions such as acupuncture, cutting, minus 78°C dry ice environment, and 90°C high temperature hot water immersion, and does not generate heat under mechanical abuse conditions such as nailing and cutting. out of control, significantly improving the safety of the car.

In terms of power capacity, GAC’s all-solid-state power battery has successfully established a full-process manufacturing process for all-solid-state power batteries by trying more than a hundred material solutions and process solutions. It has achieved the manufacturing of large-sized multi-layer stacked all-solid-state batteries with a capacity of up to 30Ah, far exceeding the current industry's highest level (10Ah-15Ah), laying the foundation for the application of automotive-grade all-solid-state power batteries.

The R&D and application of all-solid-state power battery technology will greatly enhance the performance and market competitiveness of GAC Group’s products, help promote GAC Group’s technological innovation and high-quality, sustainable development, and will also It has a positive impact on the development of the entire new energy vehicle industry.

Domestic leading, full-scenario picture-free pure visual intelligent driving system

The main battlefield of the new round of technology competition in the automotive industry is intelligent network-connected new energy vehicles. Intelligence, especially autonomous driving, has become The focus of competition. GAC Group, which has strong technological capabilities, has a leading edge in the field of intelligent driving and has many advanced intelligent driving technologies, including super parking that can complete extreme space parking, one-touch summoning for pick-up, large curvature gradient and cross-level driving, and high-speed NDA. , Urban NDA, Traffic Congestion Pilot TJP, etc., in the field of unmanned driving, the demonstration operation of Robotaxi has been achieved.

GAC’s map-free pure visual intelligent driving system launched on this Science and Technology Day can be applied to complex and changeable scenarios. Compared with the current mainstream technology route, it not only does not require high-precision maps, but also does not rely on lidar. It combines visual sensors and the industry's top AI algorithms to perceive the world like a human. It can achieve a wider range of intelligent driving with a simpler hardware system, bringing users a richer, freer, and full-scenario driving experience. .

Chen Xuewen, chief scientist of artificial intelligence at GAC Research Institute, explains GAC’s pure visual intelligent driving system without images

GAC’s pure visual intelligent driving without images The driving system has three leading capabilities in visual recognition, giving it significant advantages in the field of autonomous driving. First, the ability to understand complex traffic roads with extreme precision. Whether it is ramps, tunnels, curves or complex scenes such as intersections and bifurcated roads, this system can accurately identify and understand the structure of the road. Secondly, super traffic light recognition ability. This system uses a deep neural network to achieve accurate identification of various signal light elements, including signal light types, various symbols and colors, countdowns, and flashing states. Third, the ability to handle complex and changeable scenarios. The sensing range of this system reaches 150 meters in front of the car, 100 meters behind the car, and 50 meters left and right, which is 1.5 times the industry level. In addition to common traffic factors such as vehicles, pedestrians, riders, and small animals, the sensing categories also include carts, campsites, etc. Irregular obstacles such as tents.

In terms of decision-making and action, GAC’s purely visual intelligent driving system without pictures also performed well. Through real-time tracking of dynamic traffic objects, intent recognition and trajectory prediction, as well as a command brain driven by data and expert rules, and relying on GAC's first fluid space-time joint planning technology, this system can accurately predict the behavior of other traffic participants. , make reasonable, safe and efficient driving decisions. In addition, in parking scenarios, this system also shows excellent performance. The minimum error can be controlled to 5cm, and it can realize the most difficult three-dimensional parking space and narrow parking space parking functions in the industry.

In addition, GAC’s purely visual intelligent driving system without pictures has the ability to continuously learn and evolve. With the help of self-developed data closed-loop and simulation systems, this system can continuously iterate and optimize algorithms during simulation tests to achieve self-improvement and evolution.

It is worth noting that in the field of autonomous driving technology, GAC has simultaneously laid out two major technical routes: the mainstream "multi-sensor fusion technology" and the forward-looking "image-free pure visual technology", and GAC has two routes. All will get rid of dependence on high-precision maps. At present, the coverage rate of high-precision maps only accounts for about 6% of the country's highway mileage, which means that autonomous driving based on high-precision maps cannot be used on about 94% of the country's highway sections. However, GAC's two technical routes have achieved "navigation" It will open."
