Baidu Weidong: Radish Run User Information High Confidentiality Level Storage Data will not be used for any purpose

From November 5th to 10th, the 4th China International Import Expo (hereinafter referred to as the “CIIE”) was held in Shanghai. The conference attracted nearly 3,000 companies from 127 countries and regions. Among them, in the sub-forum on the theme of “Embrace Digital Intelligence and Create a New Future of Smart Travel Together”, Wei Dong, Vice President and Chief Safety Operating Officer of Baidu’s Intelligent Driving Business Group, focused on the issue of autonomous driving safety and shared his thoughts . In Wei Dong’s view: “Autonomous driving is safer than human driving, but it is not 100% accident-free.” Around this thinking and point of view, Wei Dong also published a signed article on self-driving safety eleven questions.

The following is the original text of Wei Dong’s signed article on self-driving safety eleven questions:

At present, the global automobile industry is undergoing profound changes unseen in a century, and autonomous driving technology-driven industrial transformation has become the first path. Entering the second half of autonomous driving, the entire industry has moved from technical verification and product building to a new stage of large-scale layout, and the safety of autonomous driving has become a key part of commercialization. How can autonomous driving be safer than human driving? In the past eight years of hard work, Baidu Apollo has eliminated safety hazards from eleven aspects to reach the safety limit of autonomous driving.

1. How to guarantee 100% security technically?

Baidu Apollo uses engineering thinking to solve problems. At the beginning of the design of Baidu’s autonomous driving system, a set of safety requirements will be put forward from various levels such as the whole vehicle, autonomous driving system, and system software and hardware. System integration, vehicle and other aspects are tested at different levels to verify whether the automatic driving system meets the safety requirements; in terms of safety mechanism, Baidu has proposed a “one-three-five” safety mechanism, which is accumulated through safety redundancy and a large number of road tests. and other ways to ensure “safety first”.

2. How to deal with the system crash during driving?

First of all, it is clear that the Baidu Apollo autonomous driving system is designed with sufficient safety redundancy to minimize the probability of failure. Secondly, most vehicles have safety officers, and in case of emergency, autonomous vehicles can quickly switch to manual driving mode to ensure safe passage. Finally, with the maturity of the “5G cloud driving” technology, cloud drivers will have a wider field of vision and discover potential safety hazards in time, and help autonomous vehicles get out of trouble.

3. How to deal with unfamiliar scenes?

Based on the design principle of pre-risk, as early as the beginning of research and development, the automatic driving system has input common dangerous scenarios into the system. If it encounters an unlisted scene, the automatic driving system will perceive the environmental data around the vehicle through lidar, millimeter-wave radar, and cameras, and obtain the precise location, category, and speed direction of traffic participants in real time through the convolutional neural network model CNN. information, so as to provide judgment basis for decision planning control module to avoid risks.

4. How to deal with emergencies such as road closure, management and control?

If it encounters road closures, control and other road conditions that cannot be handled, the automatic driving system will effectively identify and re-plan the route; if it cannot be avoided, the system will be taken over by the security officer or the cloud to solve and handle it. In the case where the manual cannot control the vehicle in time, the vehicle will slow down, pull over and park safely, etc. according to the degree of urgency, and then take measures such as double flashing, honking, and automatically contacting the call center to ensure the safety of the people on board and the surrounding vehicles. .

5. How to avoid unsafe behaviors during human driving?

Traditional traffic accidents are mostly caused by human drivers fatigue driving and non-compliance with traffic rules. Unlike traditional human driving, vehicles equipped with automatic driving systems have the advantages of being sustainable, predictable and responsive, and their driving performance is better than that of human beings.

Taking road safety as an example, the automatic driving system has an innate “rule awareness” and can rely on strong self-discipline to ensure road traffic safety; without considering charging, the automatic driving system can theoretically achieve 7* 24 hours of uninterrupted operation, there is no fatigue driving problem, and its motion patterns are basically predictable and simulated; in addition, relying on the system's real-time perception ability, autonomous vehicles can also identify the potential dangers of each traffic participant in advance, so as to improve Cope well. That is to say, autonomous driving fundamentally avoids unsafe behaviors during human driving, and ultimately achieves safer driving than humans.

6. How to ensure the safety of pedestrians on the road?

At the beginning of the design of self-driving vehicles, not only the road traffic rules are input, but also the rules of civilized driving and courteous pedestrians are added. The autonomous driving system can also identify all kinds of traffic participants in 360 degrees, and with the help of the vehicle-road coordination system, it is completely unaffected by the blind spots of human vision and poor visibility in bad weather. security.

7. How to ensure the safety of road data collected by cars

As a travel technology that integrates the cloud map of vehicles and roads, autonomous driving is also necessary to collect information in the development process. In order to prevent data security risks, in the commercial operation of autonomous driving, road information that must be collected is involved. Baidu Apollo collects legal and compliant high-precision maps through the acquisition qualifications of navigation maps and surveying maps. At the same time, all data processing The storage and storage also comply with the requirements of laws and regulations, and all kinds of information are kept confidential through complete confidentiality means.

8. How to ensure the safety of passenger information?

In terms of personal data, Baidu Apollo's travel platform "Radish Run" will collect necessary basic personal information in accordance with government regulatory requirements, and the platform will store these user information with a high level of confidentiality for compliance inquiries, and strictly protect it in accordance with data regulatory requirements The data is not used for any other purpose.

9. How to avoid the risk of hacker attack?

For the sudden problem that the autonomous driving system is maliciously attacked by hackers, Baidu Apollo will rely on hardware security chips to build a safe and reliable AI platform environment; rely on security gateways to achieve network segment isolation, access control, identification of abnormal intrusions, communication encryption, two-way Authentication, etc., to avoid the risk of hacker attacks.

10. How does the automatic driving system achieve the adaptability of different models?

At present, the unmanned models built by Baidu Apollo and automakers such as Jihu, GAC, and Weimar are all based on the maximum system adaptation for specific models. On the basis of meeting Baidu’s unified technical standards for autonomous driving, they ensure product consistency and guarantee Safe operation.

11. How to cultivate public confidence in the safety of autonomous driving?

As the hottest track in the world, autonomous driving has always been the focus of external discussions. Some people sing it well and some people sing it badly. This is a new technology that will inevitably face this stage in the promotion process. To be sure, autonomous driving is far safer than human driving, but it is not 100% accident-free. Baidu Apollo will actively face up to different voices, continue to make efforts in technology, operation, and data information, and continue to improve and iterate with the help of user feedback, to improve the safety of autonomous driving in a down-to-earth manner, and to provide a more efficient and convenient travel experience for the entire society.
