[Pacific Automotive Network Industry Channel] On June 28, the 2022 GAC TECH DAY 2022 with the theme of "Technology for the Present" was held at GAC Research Institute . GAC Group released a centralized release of Pusa OS (Pusa operating system) under the GAC Xingling architecture, the new ADiGO intelligent driving interconnection ecosystem, a new generation of super lithium iron batteries based on microcrystalline technology, and the JULANG hybrid modular architecture and Julang-hydrogen hybrid system, and also released the new hydrogen energy concept car Greenland SPACE.

OTA frequency in minutes

Based on the Xingling architecture, GAC has further independently developed the industry's first cross-domain standardized operating system for the entire vehicle - GAC Pusa OS. Pusai OS has created unified interface definitions and core components, and developed SOA cross-domain service engine, high-performance middleware engine, car cloud mirror engine, and heterogeneous execution scheduling engine, which can enable central computers, intelligent driving computers, and infotainment computers. Organic integration at the software level.

Pusai OS has the characteristics of efficient collaboration, minimalist reuse, and unified car and cloud. It effectively improves the compatibility and reusability of software, greatly improves the efficiency of software development and the speed of iteration, and makes software iteration change from the original monthly time The unit becomes the unit of minutes, bringing an unprecedented experience to consumers.

Focus on smart cockpit and smart driving

The newly upgraded ADiGO ecosystem includes two major systems: ADiGO SPACE and ADiGO PILOT, focusing on the two core user experiences of smart cockpit and smart driving.

ADiGO SPACE intelligent cockpit system is driven by specific application scenarios and has achieved four major improvements and leaps, including more natural voice capabilities, more extreme sound experience, newer ecological content, and more intelligent scene solutions.

For example, the coverage rate of the wake-up-free function reaches 95%, and the wake-up time is less than 0.6 seconds; the introduction of in-car vinyl music allows users to enjoy a new listening experience in the small cockpit, which is the collision of modern technology and century-old classics; in terms of entertainment functions Introduced top ecological content, combined with Tencent , Himalaya , Bilibili and other brands.

ADiGO PILOT intelligent driving system is equipped with the industry's most advanced 39 high-performance sensors, including 3 intelligent variable-focus solid-state lidar , 6 8-megapixel high-definition cameras, the industry's first infrared camera, and is equipped with industry-leading 8 major redundant systems equipped with high-performance computing platforms.

ADiGO PILOT advanced assisted driving realizes advanced intelligent driving with the most complete functional scenarios in the industry. It can realize automatic up and down ramps, automatic lane changing, automatic overtaking, automatic obstacle avoidance and other functions according to the navigation path. It currently covers all highways in the country and expressways in core cities.

ADiGO PILOT super parking focuses on realizing "last mile" intelligent driving, supports more than 50 complex parking scenarios, and is the first extreme parking function in the industry. It not only supports extremely small parking spaces with a spacing of 15cm, but also supports corners. Fully automatic parking of parking spaces.

ADiGO PILOT driverless is a solution for Robotaxi scenarios. It has ultra-high AI computing capabilities. It is the first time in the industry to adopt a mass-produced car-grade embedded computing platform that supports vehicle-road collaboration and 5G remote takeover. It can support Completely unmanned mobility.

New generation of super lithium iron battery technology

Following the release of three original battery technologies in 2021: "sponge silicon negative plate battery technology, super fast charging technology and magazine battery system safety technology", GAC Group officially released microcrystalline technology new generation super iron lithium battery technology (SmLFP). Compared with the lithium iron phosphate battery currently mass-produced on the market, the

super lithium iron battery has a 13.5% increase in cell mass energy density, a 20% increase in volumetric energy density, and an approximately 10% increase in -20°C low temperature capacity. Fast charging It can reach more than 2C, and the power battery life can reach more than 1.5 million kilometers (4000 weeks @80%).

A modular hybrid architecture that can cover all models

At this GAC Technology Day, it officially released the technical support of Julang Hybrid - Julang Hybrid Modular Architecture , which consists of a hybrid engine (E), It consists of three parts: electromechanical coupling system (M) and power battery (B). It adopts platform-based and modular design . It has strong compatibility and high versatility. It can derive 4 major categories and N animal combinations, adaptable All HEV, PHEV and REEV models.

The four major categories under the Julang hybrid modular architecture include economical single-speed systems, dynamic power split systems, dynamic and energy-saving multi-speed systems, and efficient zero-carbon hydrogen hybrid systems. Among them, the Julang-hydrogen hybrid system is composed of a hydrogen internal combustion engine and a GAC ​​electromechanical coupled system GMC. The hydrogen consumption per 100 kilometers is less than 0.84kg.

GAC electromechanical coupling system GMC has the advantages of high efficiency, high performance, and high integration, and is compatible with all XEV models. Within this year, GAC Trumpchi will launch a flagship MPV model equipped with high-torque GMC, with a pure electric cruising range of over 100km and a comprehensive system power of 270kW. In addition, GAC’s first pure electric supercar will also be unveiled within the year.

Greenland SPACE concept car

In addition, GAC's new hydrogen energy MPV concept car - Greenland SPACE was also unveiled on this Science and Technology Day. In terms of appearance design, it draws inspiration from ancient Chinese architecture and has both Large space and a sense of luxury.

draws inspiration from the warm and harmonious atmosphere of Chinese families sitting around the fire in the interior space layout of the car. It designs an enveloping structure "encirclement" inside and supports L4-level assisted driving systems.
