Hello, Mr. Dong! Public reports show that compared with traditional maps, the production and maintenance costs of high-precision maps are huge, and they also face the problem of insufficient timeliness. How can the company reduce the production and maintenance costs of high-precision maps in the face of millions of road miles in China? Is it necessary for high-precision maps to cover all of China's roads? How can the requirements for map timeliness be met for autonomous driving? How can the company's maps keep up with and update the changes in road information in a timely manner? Please answer

NavInfo: Hello, high-precision maps can provide prior data that is not affected by the environment in the case of beyond-line-of-sight, which becomes the necessary safety redundancy for other types of sensors, and at the same time greatly reduces the requirements for the computing power of the back-end algorithm. In particular, scenes such as intersections and ramps require map matching, which has become an important part and feature of our autonomous driving solution. At the same time, the company will also make relevant forward-looking arrangements based on market conditions. For example, the scene maps that have been mass-produced recently have a lighter data volume, lower cost, and more convenient deployment. They can also solve industry pain points such as frequent takeover of the autonomous driving system at complex intersections in a targeted manner. It is one of the forms of realization of high-precision maps to meet the actual needs of car manufacturers in the L2+ stage. For more details, please refer to the company's official account "NavInfo": "Facing the complex scenes of the city, NavInfo releases the first intelligent driving scene map", "In the post-high-precision map era, NavInfo wants to be a new Tier1". Thank you.
