Dr. Liu Zheng - Cooperation and Development of HD Map Updating for Autonomous Driving


Beijing, China, May 23, 2019—In the “China Automated Driving HD Map Technology Innovation Conference”, Dr. Liu Zheng, the China Chief Expert of DENSO attended the conference and gave a keynote speech. Dr. Liu Zheng mainly discussed with the guests how to improve the high-precision map, how to let users accept high-precision maps.



First of all, Dr. Liu Zheng introduced how Denso Corporation considers the full use of high-precision maps, and how to maintain high-precision maps to maintain high-precision maps with freshness and precision. How to provide some valuable information for high-precision maps with a simple on-board camera. Let's talk about the requirements of Denso for the future, including the current general roads and highways for autonomous driving and ADAS. From the perspective of automatic driving, we think that there will be a strong need for general roads after next year: the problem of L2 needs to be solved, for example: how to avoid Some dangers arise, how to avoid some human factors that affect safe driving during driving, etc. Only by solving these problems, high-precision maps will be accepted by people, so that customers can be assured, and it is expected that general roads and highways will be remitted in 2025. Get together and go to L4 and L5.




Secondly, from the perspective of active safety, from the aspects of people, cars, and the surrounding environment, we will explain how to achieve active safety and let drivers have more confidence to drive. It is believed that the most important thing is to let consumers walk on the road. Let consumers be more comfortable and confident to drive. Going back to the high-precision map, how does the map support autonomous driving? The previous millimeter-wave radar allowed the car to complete the ACC. With the great limitations of the millimeter-wave radar before the development of autonomous driving, the automatic driving requires a map. An accurate high-precision map is needed to tell you about the traffic environment and real-time traffic conditions, and to play a very important role in guiding safe driving. The effective collection of this information relies on a good communication environment and the appropriate POI data format.




Finally, Dr. Liu Zheng shared the cooperation program between Denso and TOMTOM, and showed the results of the experiment with TOMTOM in Tokyo, Japan. Through one year, I showed the high-precision map with video, processing platform data and test results. How to use video or captured information to enhance the freshness and quality of high-precision maps. Dr. Liu Zheng believes that the field of autonomous driving and high-precision maps cannot be separated from cooperation. The division of labor between the two parties must be clear. The cooperation will make the auto-driving high-precision map better to succeed. And stressed that automatic driving is inseparable from high-precision maps, the requirements for the vehicle-mounted device are not too high, and there is relative accuracy.


The above is the content of Dr. Liu Zheng for everyone to explain, through the practice and cooperation of Denso to provide you with the development goals and direction of the field of automatic driving high-precision map.


Earlier this year, Denso and TomTom worked together to develop a system solution that automatically updates high-definition map content. The system consists of Roadagram and CPP (Contents Production Platform Content Creation Platform). The Roadagram is a vehicle camera or such on-board sensor data inspection data is normalized and characterized as a type of symbol data, ie an in-vehicle system. CPP is a cloud computer that processes upstream data files, filters them and analyzes them into real data, then compares the real data with the HD Map, and finally determines whether there is data that has changed, that is, updates the data itself. The automatic HD map update system also has features for dynamic content generation, such as traffic information, especially congestion generation. This cooperation greatly promoted the development of high-precision map data real-time update technology, and strongly proved the value of high-precision map as a key component of automatic driving safety.
