From May 27th to 28th, the 2023 Global Open Source Technology Summit was officially held in the Zhangjiang Science Hall in Shanghai. Among them, at the "OpenSDV Software-Defined Vehicle Sub-Forum" held on the 28th, many automotive experts, experts in the open source field, and technicians gathered together to exchange and share the latest technologies, trends and ideas about software-defined vehicles, as well as software The future development and challenges of automobiles.
At the sub-forum, Xie Baoyou, the chief engineer of the basic operating system technology of the State Science and Technology Foundation, focused on introducing the foundation light series operating systems independently developed by the foundation stone, including the foundation light Linux applied to the field of smart car automatic driving, and the foundation light Intelligent operating system, Photon RTOS for smart car control domain, virtualization solution under the central computing architecture - Phonton Hypervisor , and Phonton tuning and diagnosis tool.
The operating system is the "soul" of the car. In recent years, the importance of automotive operating systems has been repeatedly mentioned. In the field of operating systems, CAS provides operating system kernel solutions for the entire domain of smart cars, provides basic underlying system functions for the upper application layer, and provides underlying operating support for functional safety, expected functional safety, and information security.
Specifically, for the vehicle control domain, the basic light real-time operating system developed by Guoke Foundation Stone can directly run on the MCU, and is committed to providing a safe operating environment for vehicle control software; Kejishi took the lead in launching Chiguang Linux to meet the actual needs of the industry in 3 to 5 years; at the same time, in order to meet the needs of high-level automatic driving, Guoke Jishi is developing a large-scale operating system compatible with Linux ecology - Jiguang Intelligence operating system; in addition, Photon Hypervisor can support running Linux and Android operating systems at the same time, running smart meters and central control entertainment services respectively.
At the same time, Guoke Foundation Stone will combine middleware and tool chain products under the SOA architecture to form a next-generation intelligent vehicle operating system solution, which will promote ecological enterprises in the automotive field to improve development efficiency on the basis of building a security technology base, and further promote Efficient technological innovation and application.
"We will open source the core technology and accept the inspection and supervision of industry experts and the public." Xie Baoyou said at the forum, "On the one hand, we provide mature and verified underlying technologies to the open source community through open source and open source, which will become the foundation of industrial technology; On the other hand, through industrial co-construction, rapid iteration on the mature basic version, extensive compatibility, and the formation of newer mature technologies. ”
At the beginning of this year, Guoke Foundation Stone successively made the Photon Linux operating system and Photon RTOS developed by the company open source. Facing the future development trend of multi-domain integration and computing concentration in automobiles, Guoke Cornerstone is also building an overall solution for the automotive operating system for the next generation of smart cars and a hybrid key kernel operating system that supports multi-core heterogeneous environments at the same time, and has plans open source.
"We also plan to donate these open source codes to open source organizations like OpenSDV to jointly build the baseline version of the industry to achieve a broader industry consensus and solve common problems in the industry." Xie Baoyou said.
In addition to the operating system, Xie Baoyou also shared the tuning and diagnostic tools independently developed by Guoke Foundation Stone. "Occasional operating system and application jitter is a difficult problem in the industry, which may cause consumer experience problems and even automatic driving safety accidents." Xie Baoyou introduced, "Basic system and application diagnosis and tuning tools can be used for Real-time and normalized root cause diagnosis of operating system and application performance, stability, business abnormal jitter and other issues can detect corner-cases in the system in advance, and can also help users discover operating system and application abnormalities in advance.”
Driven by the concept of "technological innovation driven + ecological open source and openness", Guoke Foundation will work with community developers and industry partners to consolidate basic software and become the infrastructure of the smart car era.
