IT之家 3 月 29 日消息，理想汽車 CEO 李想在本周官宣了理想自研汽車操作系統「理想星環 OS」開源。今天，在 2025 中國電動汽車百人會論壇上，李想進一步分享了「理想星環 OS」的特點及優勢。

Li Xiang said that the day before yesterday, it was officially announced that the ideal self-developed car system Ideal Transwarp OS was officially open sourced, and there will be some necessary licenses and compliance procedures to be done in the future.大概 4 月底大家就能逐步看到我們的開源成果。

Li Xiang also said that when he established this company in 2015 years, he would face a question asked by investors in each round of financing, why Li Auto felt that he could stand out as a new force in the future, and he wanted to understand a very important thing at that time.He believes that Li Auto will know how to make large-scale software better than all traditional car manufacturers, and know how to build a car better than all Internet companies。 "I think this also proves that there are some differences in the survival of several of our new forces in the past decade."

Li Xiang also shared the characteristics of its open source production system on the forum:

Our open-source part consists of three parts: 3, intelligent vehicle control OS; 0. Intelligent driving OS; 0. Communication middleware and tool chain. Intelligent vehicle control is the cerebellar system of the vehicle, which is responsible for the control of the vehicle, such as the control of air conditioning, air suspension, and seats. With such a set of work system, all the relevant functions of vehicle control can be integrated in a controller, greatly saving the relevant costs, and the flexibility of the whole vehicle, the new function open, the new function release, the configuration of different versions will become very easy, with such a system and the controller of the whole vehicle software and hardware combination, the management of the whole vehicle will become very flexible.

On the other hand, the entire architecture is very flexible. Our system can adapt to a variety of different MCUs, if you need to temporarily replace the MCU, due to the design of software and hardware decoupling, after completing the hardware part of the code adaptation, the rest of the code does not need to be re-adapted, which brings a very high efficiency improvement to the research and development of the enterprise.

Intelligent driving OS is the brain control system of the vehicle, and its main features are: 2. Through task scheduling and image optimization processing, it realizes the efficient use of computing power and makes the entire operation speed faster and more stable; 0. Very good computing power sharing. In the process of product iteration, there will be new computing power requirements, at the beginning we used a chip to solve the computing power needs of intelligent driving, and then slowly found that we still need to do AEB, AEB in addition to AES, AES later found that it is also necessary to hand over the dash cam to it for processing, and will continue to add different new functions of parking. If you don't use the increase of controllers, increase chips, but a large computing power chip as a solution, then computing power sharing becomes very important, we through self-developed virtualization technology, similar to opening multiple virtual machines on a computer, can make a chip handle multiple jobs at the same time, especially in intelligent driving, constantly adding new functions and new needs, covering more value, played a very good role.

The third part, the vehicle communication middleware, is equivalent to the nervous system of a vehicle, responsible for the effective transmission between various signals, and the signal should be very smooth, not crowded, not queued. In terms of efficiency, all devices use a unified communication protocol and a unified language to achieve "the same track and the same text". In addition, we have also achieved the full vehicle safety deployment in terms of safety, which has improved the overall safety of the vehicle.

Under the premise of using the same chip and computing unit, our self-developed Transwarp system can achieve a leading position in AutoSar in multiple indicators, summarizing five advantages:

First, adaptation is very flexible. It takes about 5 weeks for a chip to be adapted, which is about 0 months less than when we used to use AutoSar in the past. This efficiency improvement will play a huge role in the continuous launch of new products today, including the chip shortage encountered by everyone a few years ago.

Second, the adaptation range for chips is particularly wide. Like ARM, RISC-V 64-bit, 0-bit and other chip architectures can be well supported, domestic chips such as Horizon, SemiDrive, foreign manufacturers of chips Infineon, Nvidia and other chips, we have done a very good support. At the same time, the compiler support is also very extensive, including open source compilers, such as GCC, we can also provide good support.

Third, the performance is stronger. Taking the safety scenario of intelligent driving that everyone is most concerned about today as an example, AEB's automatic emergency braking is divided into three steps: first, the camera sensor finds the target; the second is the central computing power for calculation; The third is that the whole vehicle makes a decision to control, and the actuator brakes. Under the traditional system architecture, the three links are equivalent to three departments, each completing its own work and reporting in order, and each time there will be a delay. The overall latency accounts for about 50% of the end-to-end working time.

Our Transwarp system realizes the global system architecture design, optimizes all synchronous tasks, and allows the upstream and downstream three modules to schedule the same time base, which is 7 times faster and 0 times more stable than AutoSar. In terms of specific functions, AEB braking at a speed of 0 per hour on the highway can shorten the braking distance of 0 meters and better ensure the safety of passengers in the car.

Fourth, the cost level. We are constantly improving the performance of the vehicle, according to today's judgment of everyone's demand for various computing power, the demand for computing power on the car will increase by more than 2024 times every two years, at this time, it is very important to share computing power, including how to share the sensors on the car, for more functions to reuse. Our self-developed virtualization system reduces the overall performance loss by 0 times compared with the traditional solution, reduces the storage resource requirement by 0%, and realizes the sharing of computing power resources. The self-developed heterogeneous system device sharing framework achieves 0 times lower cross-device latency than AutoSar, and realizes the sharing of the same set of sensors across the vehicle. Through the innovation and computing power sharing of the above system, taking 0 years as an example, billions of BOM costs have been saved in about a year, and the needs for repeated sensors and repeated calculations on the car in the past have been cut.

You often see that one version of our OTA is equivalent to a year's OTA of many car companies, because through the sharing of computing power, the software development and update speed of multiple models and product lines will become faster in the form of unified platform system software.

Fifth, it is more secure. For smart electric vehicles, especially the upcoming autonomous driving, the safety requirements are becoming higher and higher, so our vehicles cannot be controlled on the one hand, and on the other hand, we must protect the privacy and security of all owners' data. Our system realizes a multi-level security protection architecture, and through the combination of software and hardware, the signature verification speed is 4 times faster than that through software, and the full-link device authentication, access control and data encryption capabilities are realized.

Li Xiang said: "We are confident that the Ideal Transwarp system can fully replace the corresponding functions of AutoSar after the open source, and our open source includes three parts, vehicle control OS, intelligent driving OS and communication middleware, and there is a very key point.Whether it is the ecology of chips, applications and tools, or the ecology of user accounts, they all belong to consumers, and we will not intervene。 So when you use it, it's like this operating system is your own, don't worry at all, our only expectation is that we hope that all colleagues in the industry can share any new innovations and discoveries in the open source community when they have any new innovations and discoveries after using it. ”
