Jiangnan began to enter the rainy season in late June. Rainwater continued from morning till night. The Suzhou Automobile Research Institute of Tsinghua University in Suzhou was greeted by the sound of rain. It seemed like a grand but significant one. Laboratory unveiling ceremony.
On June 20th, the Tsinghua-Swiss Intelligent Vehicle Testing Laboratory jointly established by the Suzhou Automotive Research Institute of Tsinghua University and Suzhou Lingchuang Ruidi Measurement & Control Technology Co., Ltd. was formally launched in Suzhou. 'Electrification, intelligentization, sharing for the car The industry has brought unprecedented opportunities. ' Professor Cheng Bo, Dean of the Suzhou Automotive Research Institute of Tsinghua University, said in his speech that the establishment of the laboratory has helped companies to make solutions in the intelligent network connected technology field. On the other hand, it has promoted the industry through hard work. Development, the formation of a system to ensure the safety of travel.
From the point of view of national strategy and industry development, there is great potential for smart car testing related services and equipment market demand. Director of Intelligent Networking Center, Suzhou Automotive Research Institute, Tsinghua University, and Dai Yifan, Director of Tsinghua-Swiss Intelligent Car Testing Laboratory The purpose of the establishment of the laboratory is: From the perspective of a third party, provide the public service platform for the industry and provide the most basic technical support.
It is understood that the lab will have two main tasks: testing and service of smart automobile modules, and building of ADAS scenes. The former includes automotive sensors such as millimeter-wave radar and ultrasonic radar, and testing of V2X-related technologies. It is a strong point of monitoring and control in Swiss; Mainly based on the Chinese standard scenario library generation and simulation, Chinese characteristics of traffic scene design, road design and other content, Tsinghua has a prominent advantage in this regard.
Frequent accidents Smart cars need no validation for their own safety
“How should the safety of the smart car itself be verified? According to what kind of standards, what kind of norms, what kind of methods to carry out a reasonable, rigorous, responsible assessment of the quality of the product?” Just started talking, The wave first throws up a number of questions to raise the discussion. 'Now the entire industry is keen on breakthroughs in technology, the realization of functions, and the improvement of performance. After these technologies are truly realized, how do they deal with extreme conditions? In addition to technical issues, How to solve the problems of efficiency, safety, and ethics?'
The problem of wave-burrowing is largely due to the auto-driving traffic accidents that Uber, Tesla and other companies have successively experienced. In Cheng Bo’s view, it must not be possible to take technical brutal growth. The human life is a mouse experiment. From a worldwide perspective, the test standards and specifications of the smart network-linked automobile are at most a few conceptual and principled ones and cannot be dropped.
A key task of the 'Tsinghua-Swiss Smart Car Testing Laboratory' is to promote the construction of test standards for automotive sensors. ' Cheng Bo said, 'Intelligent network car to replace people's eyes, ears, hands and feet, etc., need to obtain Images, radars, and V2X, etc., transport a lot of traffic information. These information must be concentrated on the car's platform for information fusion, and then perform multi-dimensional comprehensive judgments. In this context, we need to verify whether these sensors are qualified or not. Is sensor-acquired information based on the perception of the environment accurate?'
Whether it is abroad or domestic, what kind of sensor is a good sensor, which can reach the vehicle standard? There is no uniform standard, these have caused great difficulties to the development of the entire industry. Chengbo hope, 'Tsinghua - Rui Di Smart car testing laboratory helps enterprises to make solutions. On the other hand, through their own efforts, they can promote the development of the entire industry as quickly as possible. In terms of traffic and human security, they can form a security system with Chinese characteristics.
Grab the opportunity Chinese test scene library is very important
In the development of intelligent networked autos and autopilots, the construction of a test scenario library is crucial, and an important task for the establishment of the 'Tsinghua-Swiss Smart Car Testing Laboratory' is to establish a smart networked car with Chinese characteristics. Test scenario library. '
“The traditional car testing system does not have the concept of a scenario library. Even if it exists, it is very simple. For example, we do a straight hundred kilometers of accelerated testing, and there are some differences in the test and R&D system of intelligent networked vehicles, including the construction of test scenario libraries. “ Dai Yifan believes that for smart cars and autopilot, different scenarios must be imported into the vehicle system to verify that the system can safely and efficiently respond to relevant scenarios, and the test scenario library must be able to support the software from the loop. (SIL), hardware-in-the-loop (HIL), vehicle-in-the-loop (VIL) road closure test, open road test, etc.
'Some road limit tests cannot always be placed on the real road, then it has become a road killer. Limit testing is often required in the laboratory.' General manager of Suzhou Lingchuang Ruidi Measurement and Control Technology Co., Ltd., Tsinghua-Swiss intelligent automotive test experiment Room deputy director Zheng Kai said.
There is no precedent for the construction of such a library of scenes, which requires China to establish itself. 'The building of a test scene library with Chinese characteristics requires a lot of data support, including data on traffic violations, data collected by road surveillance cameras, and data collected by driving recorders. The data, as well as vehicle sensors, GPS, etc. The data recorded by the sensors, etc., are analyzed from these data, extracted from the methodology of probability, which scenes are dangerous, and dangerous scenes are useful. After the introduction of the scene, the scene was summed up, and a series of test systems were combined with the test platform. Finally, through the test, the evaluation results were obtained. In the end, the vehicle responded to the scene. The response was not good.
Service Industry Supports China Smart Car Standard Verification
Zheng Kai introduced that 'The Tsinghua-Swiss Smart Car Testing Laboratory' has four functions. The first one is to serve as the Chinese smart car standard verification support platform; the second is to do the Tsinghua University Suzhou Automotive Research Institute in the intelligent network of automotive hardware. The core testing and testing support organization in the ring simulation field; the third is the core supporting platform for the Jiangsu Intelligent Network Innovation Center testing business; and the fourth is the undertaking unit for the testing business of the Vehicle Connectivity Engineering Laboratory in Jiangsu Province.
When it comes to testing standards, Zheng Kate proposes an example of radar. 'Whether it is a product development company, a component integration company or a vehicle company, all need to test a car radar. Testing requires testing equipment and testing services as a third party. ,, 'Tsinghua-Swiss smart car testing laboratory' can provide this kind of service. ' Zheng Kai said, 'small R & D team does not have the financial strength to buy test equipment, willing to look for us to do the test, we measured down to this The results are analyzed and feedback is given back to the R&D team for product improvement. The component integration supplier needs to test and certify the large-scale production radar that he purchased. The same problem also exists for the entire vehicle company, which needs to be increased by the component integration supplier. The entire product is tested and evaluated. '
At present, vehicle radars are in a state of flourishing in the country. Zheng Kai believes that when the standard comes standard, “two passengers and one dangerous” vehicle will be forcibly installed in the vehicle anti-collision warning, lane departure warning system, which will lead to radar The surge in supply, which also means the beginning of survival of the fittest, said Zheng Kai, 'At least half of China's R&D institutions and component integration suppliers will communicate with us on how to design a product program to meet relevant standards verification requirements. It is expected that both radars and cameras will eliminate a large number of enterprises, especially some low-quality products that lack both laboratory data validation and road operation feedback.
