ADiGO 3.0 Intelligent Driving and Internet Ecosystem (hereinafter referred to as "ADiGO System") has been upgraded in three aspects: autonomous driving system, intelligent IoT system and artificial intelligence, and continues to create an extraordinary travel experience for users. In terms of autonomous driving, the newly upgraded autonomous driving system achieves L3 autonomous driving experience on highways through 23 intelligent sensors and high-precision maps. The hands-off function on highways can completely free users' hands and feet and relieve driving fatigue. The autonomous parking system completes parking and pick-up through one-button remote control of the mobile phone, achieving long-distance, cross-floor L4 low-speed autonomous driving. The second is the newly upgraded intelligent IoT system. In terms of hardware, it is equipped with the world's first and the industry's most powerful Qualcomm Snapdragon 8155 in-vehicle hardware platform, which provides more powerful computing power for the car; based on the world's first integrated 5G V-BOX in-vehicle intelligent communication system, it opens up the 5G interconnection data channel to help upgrade the autonomous driving function; in addition, it also provides users with what you see is what you get AR-HUD real-scene navigation; and creates a four-screen multi-mode interactive sharing architecture. In the face of the epidemic, GAC's "G-HEALTH" healthy ecological cockpit is equipped with CN95 high-efficiency filters, ultraviolet sterilization, Chinese medicine fragrances and 360° physiological health intelligent monitoring functions to make your travel healthier. Third, ADiGO will increase the integration of artificial intelligence technology and automotive travel. It has already been implemented in autonomous driving, AI smart partners, driver recognition and other aspects. Relying on cloud platforms and big data technology, integrating vehicle data and ecological resources, it can provide users with content service recommendations for thousands of people in vehicle scenarios, build a full life cycle service system for smart cars, and provide exclusive travel services for every ADiGO user.

GAC's 3DG graphene preparation technology has independent intellectual property rights, and has formed a preliminary process package and engineering capabilities, and has made great breakthroughs in downstream application fields. Feng Xingya introduced that in order to better promote the commercial application of graphene technology, a graphene high-tech industrialization company will be jointly established in the form of GAC investment + employee investment. Innovative systems, mechanisms and management models will not only help technological innovation, but also help young scientific and technological talents achieve their entrepreneurial dreams and realize a more colorful life value.

Pei Feng, Director of the Leading Technology Department of GAC Research Institute, introduced the research and development of GAC's graphene technology

GAC Group has been studying the large-scale preparation of graphene since 2014. It has independent intellectual property rights for the 3DG graphene preparation technology, and has also applied graphene materials in many fields such as fast-charging lithium-ion batteries, supercapacitors, lithium-sulfur batteries and lightweight body materials. GAC's 3DG preparation method is simple, stable and efficient. The three-dimensional multi-level pore structure graphene obtained can effectively overcome the cost disadvantage, and the production and preparation cost can reach 1/10 of the conventional preparation method. Based on the excellent conductivity and special three-dimensional structure of graphene, GAC has developed a super-fast charging battery that can be fully charged to 80% in 8 minutes, can be charged in 10 minutes, and has a range of 200-300 kilometers. At present, GAC has preliminarily verified graphene technology from multiple levels such as battery cells, modules, and vehicles. It can be foreseen that after the completion of mass production tests, a new era of electric vehicles will come.
