Why "Star Spirit Architecture"?

If the car is compared to the human body, the mechanical structure of the car is equivalent to the human skeleton, the power and steering are equivalent to the human limbs, and the electronic and electrical architecture is equivalent to the human nervous system and brain, which is the key to the car’s information exchange and complex operation.

In the traditional electronic and electrical architecture, dozens of controller nodes in the vehicle are connected through the CAN bus, and each node is only responsible for the realization of a single function. To realize the transition of intelligent experience, the centralized computing electronic and electrical architecture is the foundation.

Xingling Architecture is the industry’s first mass-produced automotive cloud integrated centralized computing electronic and electrical architecture. As an advanced electronic and electrical architecture, Xingling Architecture adopts the configuration of "central supercomputer + regional control", which is composed of three core computer groups of automotive digital mirror cloud, central computer, intelligent driving computer, and infotainment computer, as well as four regional controllers.

GAC Xingling Electronic and Electrical Architecture

Compared with GAC’s previous generation of electronic and electrical architecture, the computing power of the Xingling architecture is increased by 50 times, the data transmission rate is increased by 10 times, the wiring harness circuit is reduced by about 40%, and the controller is reduced by about 20; it also has eight core capabilities such as vehicle-level OTA upgrade, full life cycle big data, all-round protection information security, and vehicle service SOA.

Equipped with the Xingling architecture, the E8 is equivalent to having a "super brain" and "sensitive nerves", achieving a comprehensive evolution of the technical base, providing a solid foundation for "E million possibilities to install a home".

Smooth and efficient: the "speed" brought by the Starspirit architecture

The increase in computing power and data transmission rate brings extreme speed. The Xingling architecture uses Gigabit in-vehicle Ethernet as the backbone network, combined with TSN (Time Sensitive Network), SOME/IP (IP-based Scalable Service-Oriented Middleware) and other technologies to greatly improve the data transmission rate and efficiency of the vehicle; its core computer uses multiple multi-core heterogeneous SoCs (System-on-Chip), forming a strong real-time processing capability and service-oriented high-performance computing power, which greatly enhances the processing efficiency of the complex Instruction Set Architecture.

Voice assistant that "listens in seconds, understands in seconds, and responds in seconds"

Thanks to the "speed up" of the Xingling architecture, the E8’s intelligent interaction is responsive, just like mobile phone communication from the 2G era to the 5G era, allowing the new voice assistant to "listen in seconds, understand in seconds, and respond in seconds". Call "Xiaoqi", the voice assistant flashes briskly without any delay; even in scenes such as noisy environment and children crying in the car, the automatic speech recognition accuracy rate can reach 97%, which is at the top level in the industry. In addition to the "on-call" responsive response, the E8 voice assistant can also be visible in the whole scene, just like a "voice mouse", which can flexibly access all pictures and texts on the screen. Voice assistants can also conveniently broadcast programs, control air conditioners, adjust seats, etc., allowing users to drive without being in a hurry and have more energy to take care of every family member in the car.

In addition to the voice assistant, the "speed" of the Xingling architecture also leaves ample computing power space for the intelligent driving function; the rich intelligent driving auxiliary features can cover a variety of scenarios such as urban commuting, weekend travel and long-distance travel, making the E8 agile.

Scene Definition: The Star Spirit Architecture satisfies the whims of the family

Mom’s beautiful living room, dad’s ever-changing study, brother’s smart video room, sister’s dream castle… E8 can meet the individual needs of every family member. This is not only the ever-changing space in the car, but also the ever-changing smart scene.

With the support of the high integration of Xingling architecture and SOA service, the i-SPACE intelligent creative scene function can create a sense of immersion with one click. For example, in winter, the "bonfire" mode can create the atmosphere of the "fireplace" in the car. The warm fire and the sound of firewood burning, combined with the comfortable seat heating, instantly create a comfortable and warm living room.

i-SPACE "A Campfire" mode

In addition, the GAC Rubik’s Cube scene co-creation platform developed based on the Xingling architecture not only has official scenes, but also gives users the ability to customize personalized scenes. The Xingling architecture uses V-DSL language (a specific description language in the field of in-vehicle software) and in-vehicle low-code technology to serve all more than 2,000 functions of the vehicle and encapsulate them into code blocks, so that the functions can be arbitrarily arranged and combined in a graphical interface like "building blocks". Users can recombine and call all functions in the car to define exclusive personalized travel scenarios for each family member.

For example, if a user wants to create a "pick up a child from school" scene, it can be set in the mobile APP or in the car "My Scene": If the "rear seat belt is fastened" and the voice says "go home", perform actions such as "navigate home", "close the windows of the whole car" and "play children’s books", so that the E8 can accompany the child home from school like a big friend.

Continuous Evolution: The "Vitality" bestowed by the Star Spirit Architecture

In the past, when a car was sold, all the functions on the car had been fixed, and the application of OTA (over-the-air upgrade) technology made it possible for the car to "evolve". However, under the traditional distributed architecture, software and hardware are integrated to achieve a cross-system function, and only one component can be upgraded independently. As long as one of the components is not successfully upgraded, all of them have to be repeated, and the scalability is very limited.

Xingling architecture truly realizes the OTA upgrade of vehicle-level software through the integration and reconstruction of data, software, and processes. Thanks to the highly centralized design, Xingling architecture interfaces more than 800 sensors and actuators of the vehicle, connects to the backbone network through the area controller, and decouples the corresponding sensing and control algorithms, and moves up to the core computer, so that function iteration only needs to upgrade the core computer through OTA, truly realizes the parallel upgrade of multiple components in a single task, and realizes the iteration of vehicle-level cross-system scenarios, so that the car can grow like life.

Xingling architecture supports vehicle-level OTA upgrades

In addition, the high-speed Ethernet and high-performance platform of the Xingling architecture also greatly improve the efficiency of upgrade package download, analysis, and backup, making OTA upgrades non-sensory and efficient. Compared with the updated single-node function of the previous generation of electronic and electrical architecture components, the efficiency of the Xingling architecture to optimize and upgrade for the same function has increased by more than 4 times. High-speed iteration of new scene functions allows E8 to accompany every family member like a new friend from time to time.

Information Security: Xingling Architecture Redefines Intelligent Security

In the era of intelligence, the security of automobiles has also been given new connotations, no longer limited to the protection of people, but expanded to the protection of information security such as data, information, and software – to protect car software from attacks and user privacy data from leakage.

Xingling Architecture has adopted a new concept of "defense in depth" in information security and established a comprehensive information security defense system with a full life cycle. Based on the powerful computing power and flexible deployment characteristics of Xingling Architecture, an in-vehicle security monitoring and defense system with the central Control Unit as the core has been built, and a number of security protection products and systems have been tailor-made, including a desensitization system to protect personal privacy data, an encrypted transmission system to protect the security of vehicle data transmission, an intrusion detection prevention system to protect the safety of vehicle operation, and a situation awareness system to protect the security of cloud platforms. By building a linkage mechanism between systems, an overall security protection network is formed, and a national commercial secret algorithm is added to the communication link to protect the data security of users’ cars and clouds. Let every family member enjoy the convenience brought by intelligent services, and their privacy data can also be protected, allowing them to enjoy safe travel.

Xingling architecture allows every family to enjoy an intelligent experience with peace of mind

Based on the Xingling architecture, Trumpchi’s new energy E8 has achieved a comprehensive evolution of intelligence – responsive to family needs, on-call, often new, flexible personality – with thousands of possibilities for home.

The powerful capabilities of the Xingling architecture are far more than these. It is the foundation of intelligent travel in the 3.0 era of family cars, the core of building a full life cycle product system for automobiles and promoting the continuous evolution of user experience. It will carry the infinite possibilities of intelligence and continue to provide users with smarter and more valuable travel experiences.
