Urban auxiliary driving compete for "get on the car": Xiaopeng Automobile to the left, and Zhixing to the right at the end

With the technology iterative, the auxiliary driving function of the vehicle has entered a higher stage competition.

On September 17, Xiaopeng Automobile announced that its city's NGP intelligent navigation auxiliary driving began pilots. It is understood that the P5 owner who currently pushes the user who has submitted a smart driving assistance proposal, after the relevant procedures are reported and the approval is completed, they will be published to all Xiaopeng car owners as soon as possible. Due to different local policies, the above -mentioned auxiliary driving functions are limited to Guangzhou cities.

The so -called urban navigation auxiliary driving is based on the route set by the user to help users realize the high -speed scene from point A to urban B to point B, but compared to semi -closed and road structure There are many road factors such as vehicles and motor vehicles, so the auxiliary driving function on urban road development is more difficult to mass production.

It is worth noting that there are two main schools in the industry navigation auxiliary driving system in the industry: one is the "Multi -sensor fusion+ high -precision map" route used by domestic manufacturers such as Xiaopeng Automobile; the other is the autonomous driving technology company The "emphasis, light map" route proposed by Zhixing. At present, these two genres are driving side by side to accelerate the deployment of urban navigation auxiliary driving systems.

Enterprises call for high -quality maps to "keep fresh"

The industry generally believes that autonomous driving technology should have three elements- "perception, decision -making, and control". The "perception" and "decision -making" of these three major elements are inseparable from the support of high -precision maps.

Compared with ordinary navigation maps, high -precision maps are more accurate, more data dimensions, and more accurate positioning. Like the curvature, slope, lane line position, type, width, and elements of traffic signal lights, traffic signs, roadside landmarks, etc., high -fine maps can be included. This information is very important for urban navigation auxiliary driving.

At present, Weilai (ES8/ES6/EC6) uses Baidu high -precision map to achieve NOP pilot driving functions including autonomous lanes and upper and lower ramps. Let's realize autonomous driving on highways.

"NGP intelligent navigation auxiliary driving systems are particularly outstanding in the scenes of weak weather and weak signals through tunnels. This is what those competitors who rely on visual solutions are not available. "Xiaopeng Automobile believed.

However, the current high -quality map is also limited. The first is that the high -precision map is slower and the collection costs are high. At the same time, there are also problems with the data of the data of the data ground map, the data interconnection standard, and the Internet of the car.

Wu Xinzhou, vice president of Xiaopeng Automobile, said that the "freshness" of high -precision maps in the market scene is very critical. I hope that when NGP is released, it can have the ability to update the high -precision map in the "sky" as a unit.

On the other hand, the National Natural Resources Department issued the "Notice on Promoting the Development and Maintenance of Geographical Information Safe in Smart Connected Motors" (hereinafter referred to as the "Notice"), which clearly stipulated and required the production and painting production of high -precision maps. The "Notice" requires the surveying and mapping and drawing of high -precision maps, which can only be issued a legal operation of enterprises that navigate electronic maps to produce -level surveying and mapping qualifications by the state. This means that the qualifications of high -precision maps are tightening.

"Get rid of" high -precision maps?

At this stage, there are still many problems at the level of high -precision maps. Therefore, it does not rely on high -quality maps to become a realistic demand for automobile companies and technology companies in developing high -level auxiliary driving functions. Huawei's executive director, terminal BG CEO, and smart car solution Bu CEO Yu Chengdong said in public that autonomous driving still uses high -precision maps, but future development should not depend on high -precision maps.

In addition, Tesla CEO Elon Musk has also repeatedly stated that it is not "cold" for high -quality maps. The map loses flexibility, and cannot be flexibly responded according to the road conditions as the real driver. "

Against this background, autonomous driving technology companies Zhixing and the slot Zhixing and other companies have proposed the "emphasis on perception, light map" route solution. "Under the technology that is aware of it, you can achieve urban auxiliary driving functions without a high -precision map." Pan Xing, the technical director of Zhixing, told the Daily Economic News reporter.

It is worth noting that to improve perception, it means that more laser radar needs to be equipped on the vehicle. For example, the Mocha DHT-PHEV lidar version of the Mocha DHT-PHEV laser radar version equipped with the Sizo City is equipped with 2 125-line lidar, 5 millimeter wave radar, 12 ultrasonic wave radar and 12 high-definition cameras. It is reported that the model is mass -produced in September and will be released during the year.

In addition, in Gu Weizhen, CEO of Zhixing, the maintenance of urban roads, dense vehicles, narrowing space, and diverse urban environment are the four main problems existing in urban roads.

In this regard, Smart Xing has upgraded its data intelligent system Mana accordingly, and the focus is on perception of intelligence and cognitive intelligence.On the perception system, Zhixing adds special recognition capabilities to the status of vehicle signal lights such as brake lights, turning lights, etc., so that the vehicle can well predict the motion intention of traffic participants.Some analysts believe that in the current implementation of urban navigation auxiliary driving systems, there are two benefits that do not rely on high -quality maps: First, it can directly avoid the limitations of policy approval brought by high -precision maps, so that the plan can quickly land more cities in more cities in cities.; Second, it can directly reduce the cost brought by high -precision maps."In the future (enterprise) will definitely reduce the dependence on the map through stronger perception, but this will need to be completed in stages." Said Hou Cong, co -founder of Qingzhou Zhihang.
