Recently, at the 15th China Automotive Blue Book Forum, Amap officially released the new HQ Live MAP for the automotive industry . It is committed to high-quality data products that retain a certain degree of accuracy while having the advantages of freshness and urban coverage . Help partners accelerate the deployment of advanced assisted driving services in all scenarios and jointly bring users a better driving experience.
"In recent years, 'emphasis on perception and light on maps' has been constantly discussed. As a professional provider of digital map content, navigation and location service solutions, AutoNavi recognizes this trend." said Jiang Rui, general manager of AutoNavi Map Automotive Business Center , but "light map" does not mean that the market no longer needs maps, but that it needs a live map that is "lighter" than HD MAP to meet the development needs of partners and the industry. "HQ Live MAP is our current optimal solution based on the general trend and weighing the current status and pain points of advanced assisted driving."
Perception and maps are not either/or, but fusion and symbiosis.
In recent years, with the continuous evolution of technology and continuous improvement of products, advanced assisted driving services have become more and more recognized by users. According to data released by many automobile companies, the user penetration rate of advanced assisted driving in high-speed and expressway scenarios is very impressive, and the mileage ratio is close to 50%; while the ordinary road scenarios in urban areas are limited by urban coverage and are still at a low level. Ascendant state.
" For now, high-speed and expressway scenarios are still the forefront of advanced assisted driving. " Jiang Rui believes that the key to further breakthroughs in this field lies in whether the current industry pain points can be solved, and this is also " The core reason for the emergence of the argument of "emphasis on perception and light on maps".
At present, although the HD MAP solution has advantages in map accuracy, due to the difficulty and high cost of production technology, it can only achieve a quarterly update frequency, which can easily lead to inconsistencies between the map and the real world over time; when on the highway Safety and experience problems are also prone to occur when special events such as construction, accidents, and maintenance occur.
On urban roads with more complex road network structures, more changes, and more diverse traffic participants, similar pain points are more obvious. This has led to the rapid implementation and popularization of HD MAP on ordinary roads in urban areas, which has always been an industry problem.
On the other hand, Jiang Rui believes that although cars currently have the ability to sense the surrounding environment of the vehicle, the perception system is still unable to clearly see, understand and express information such as vehicle obstructions, irregular road networks, complex intersections, and traffic regulations. Therefore, maps still play an indispensable role as the underlying infrastructure that provides global prior information. " A high-quality advanced assisted driving experience is inseparable from comprehensive support such as easy-to-use navigation path planning, professional static data, real-time dynamic data and rich experience data. "
According to test data provided by third-party media, the experience and ratings of advanced assisted driving using the "pure perception" solution in multiple dimensions such as safety and experience are still inferior to the collaborative combination of "perception + map".
"'Emphasis on perception, light on map' has never been either/or, but should be a symbiotic relationship." Jiang Rui said that in the era of emphasis on perception, a lighter living map is needed to help partners' advanced assistance Driving services take into account experience, quality and cost, becoming a better solution to help the industry further upgrade.
Real-time updates based on visual crowdsource collection
It is understood that the HQ Live MAP released by AutoNavi combines the advantages of HD MAP and SD MAP. Although HQ Live MAP cannot reach the level of detail of HD MAP (absolute accuracy 50cm, relative accuracy 10cm) in terms of accuracy, it is sufficient for advanced assisted driving scenarios (high-speed and urban expressway scenarios: absolute accuracy 1m, relative accuracy 30cm; ordinary road scene in urban areas: relative accuracy 1m ) - and because unnecessary map elements in ordinary road scenes in urban areas are simplified, production and deployment costs are reduced to achieve the purpose of being lighter but more practical.
More importantly, compared with the original update frequency of "quarterly", Amap HQ Live MAP can achieve real-time updates on a daily basis .
"The large-scale application of visual crowdsource collection technology based on the compliance platform is an important cornerstone for the birth of HQ Live MAP, and it is also the core advantage of AutoNavi to meet the development needs of partners and the industry." Jiang Rui introduced that AutoNavi passed Self-developed crowd-source equipment is deployed on a large scale to a large number of logistics vehicles, industrial vehicles, dispatch vehicles, etc. within the ecosystem to achieve significant efficiency improvements in the entire process from discovery, collection, production to release, thereby building a win-win integrated map ecosystem . system, and worked with multiple partners to create a “living map”.
It is understood that AutoNavi HQ Live MAP can currently cover highways and urban expressways nationwide, and has been open to industry cooperation; for ordinary roads in urban areas, AutoNavi HQ Live MAP will support 50 cities in 2023. It will be deployed in more than 100 cities across the country in 2024, and it is expected to be open to industry cooperation in December 2023.
A living map where humans and machines co-drive and humans and vehicles co-guide
The gradual popularization of advanced assisted driving is essentially the evolution of map navigation technology. Navigation has evolved from simply "guiding people" in the past to "guiding people + guiding cars" and "human-machine co-driving" .
“Because of this, the guide and the guided vehicle need to be based on a map and have sufficient professional accumulation in both aspects, so that advanced assisted driving can accurately understand the user’s navigation path, avoid driving the wrong way, and allow users to enjoy more accurate Convenient and more 'veteran-like' driving experience." Jiang Rui said that from a long-term development perspective, the current way of segmenting map data products based on accuracy is not reasonable, but should be segmented from an application perspective, such as road level, Lane level, positioning layer, etc. to meet the needs of different scenarios . "But we must ensure that it is based on the same picture."
As China's leading provider of digital map content, navigation and location service solutions, "making a good map" has been AutoNavi's original intention since its establishment in 2002. Over the past two decades, it has accumulated rich technologies, products, Ecological capabilities, whether from the perspective of "guiding people" or "guiding vehicles", are in a leading position in the industry. Up to now, AutoNavi has more than 20 car company partners in advanced assisted driving, and has served hundreds of thousands of mass-produced vehicles. These are all brand-new HQ Live MAP products that can serve partners and the industry well. foundation.
It is reported that as the industry as a whole vigorously develops sensing technology, HQ Live MAP will also be rapidly updated and iterated. While building basic technologies and capabilities, we will also integrate and customize differentiated and personalized products according to the needs of different partners to help the implementation of advanced assisted driving products to the greatest extent, and ultimately create a brand based on professional navigation and strong ecological capabilities. Zhang Geng's high-quality live map allows users to enjoy a more complete experience of "human and vehicle co-guiding" and "human and machine co-driving".
"In the automotive industry, AutoNavi's attitude has never changed, which is to focus on building products and technical capabilities, and make a living map to help our partners provide users with a better and more convenient driving experience." Jiang Rui said .
