Prime-precision Positioning Analysis: from L2+ to L3, high-precision built-in navigation and positioning will grow to be the usual
With the improvement and growth of the independent using trade, 5G communique and Beidou navigation packages are turning into increasingly more mature, and the high-precision positioning marketplace has observed building alternatives. From 2022 to 2025, independent using will regularly evolve from L2/L2+ to L3/L3+. Prime-level independent using has upper necessities for positioning accuracy which must succeed in the centimeter point. This promotes the additional building of high-precision built-in positioning era.
L3 independent using is heading for mass manufacturing, and built-in navigation positioning turns into the usual
In March 2021, Honda formally launched the L3 independent manufacturing automobile, Honda Legend EX (which got L3 independent using certification from the Ministry of Land, Infrastructure, Delivery and Tourism of Japan) supplied with the Honda SENSING Elite clever using device, high-precision positioning modules, sensors and a three-D HD map.
Honda has produced 100 devices of L3 independent fashions, which might be leased and bought to customers in Japan for 3 years, permitting customers to pressure on designated roads in Tokyo.
In December 2021, the German Federal Motor Delivery Authority (KBA) granted device popularity of Mercedes-Benz’s L3 independent using device at the foundation of the technical approval law UN-R157 (UN Law No. 157 – Automatic Lane Protecting Methods (ALKS)), permitting the sale and using of L3 independent cars from a felony point. It is a leap forward in heavily produced independent using era.
In keeping with Mercedes-Benz’s plan, its two flagship sedans, S-Elegance and EQS, shall be supplied with the L3 independent using device (together with a high-precision positioning module + HD map) in the beginning. It’s anticipated that customers will have the ability to acquire L3 Mercedes-Benz automobiles within the first part of 2022. The contracting states of UN-R157 come with EU nations, the UK, Japan, South Korea, Australia, and many others., which means that that Mercedes-Benz’s L3 independent cars will also be bought in those nations.
China has no longer legally allowed L3 independent cars to be at the street, however L2+ (just about L3) independent fashions were introduced intensively to this point. In keeping with the statistics of ResearchInChina, the meeting charge of L2 independent passenger cars exceeded 20% in China in 2021. One of the crucial L2 fashions have completed high-speed pilot independent using through putting in high-precision positioning and HD maps. For instance, Xpeng P7, NIO EC6, ES6, ES8, GAC Aion V, Aion LX, Nice Wall WEY Mocha and different fashions will also be supplied with not obligatory high-precision positioning modules. FAW Hongqi E-HS9, HiPhi X, 2021 Li ONE and different fashions are supplied with high-precision positioning modules as same old.
Along with the present heavily produced fashions, OEMs have successively introduced greater than 10 fashions supplied with high-precision positioning era since 2021, corresponding to Xpeng P5, NIO ET7, Neta U Professional, Aion V Plus, Aion LX Plus, Nice Wall Mecha Dragon, BAIC ARCFOX αS Hello, and many others.
These days, a unmarried positioning era can not meet the excessive precision required for independent cars. The answers utilized by OEMs principally use multi-sensor built-in positioning era. Along with built-in navigation modules and HD maps, applied sciences corresponding to visible SLAM and Lidar are extensively utilized.
Relative positioning can’t be used with same old HD maps, as a result of their coordinate methods, information codecs, interfaces, and timelines are utterly other. Usual HD maps should be used with absolute positioning. Due to this fact, the present mainstream positioning era is that GNSS, IMU, and HD maps cooperate and supplement each and every different to shape a high-precision positioning device for independent using.
Baidu: It’s been laid out for a few years in built-in positioning era, and can give self-positioning device and centimeter-level built-in positioning answers in keeping with GPS, IMU, HD maps and knowledge from a couple of sensors.
Baidu Apollo’s analysis and check effects display that GNSS-RTK can duvet 65% of built-in eventualities with the mistake of not up to 20cm, the combo of GNSS+IMU can duvet about 85% of the eventualities, and the high-precision positioning device consisting of GNSS+IMU, sensors and maps can succeed in 97.5% protection.
The mixing development of high-precision positioning era is plain
(1) Impartial positioning field
In relation to product shape, the present car built-in navigation device with high-precision positioning basically exists within the type of a positioning terminal, this is, a positioning field (P-Field).
As a small ECU liable for high-precision positioning, P-Field can give positioning information to the map module to understand the matching of positioning era and HD maps.
With the development of era, along with integrating GNSS and IMU, P-Field will additional combine HD maps. By means of HD maps and high-precision positioning, extra correct positioning information will also be got.
Asensing: In April 2021, an HD map field was once introduced, which integrates IMU, RTK, car pace, ADAS cameras and HD map information. In keeping with the fusion of MEMS high-precision inertial navigation information and high-precision satellite tv for pc positioning information, the HD map field provides belief information of ADAS cameras and HD maps to make the lateral error not up to 0.2 meters and the longitudinal error not up to 2 meters at 95% self belief period.
(2) Integration with wi-fi communique modules
The mixing of car wi-fi communique modules and GNSS high-precision positioning is turning into a development. For instance, the Hongqi E-HS9 introduced on the finish of 2020 is provided with a C-V2X good antenna evolved with Neusoft collectively and built-in with a GNSS receiver; Buick GL8 Avenir, introduced on the finish of 2020, is provided with Quectel’s AG15 and AG35 modules and GNSS era.
Joynext: At the foundation of the standard T-Field module, it integrates V2X, Bluetooth key, high-precision positioning and HD map output, offering sub-meter high-precision positioning. Joynext has signed a freelance with NIO’s 5G-V2X platform undertaking to give you the latter with 5G-TBOX and 5G-VBOX, which shall be carried out on ET7 in the beginning.
Quectel: It has cooperated with Qualcomm and Qianxun SI to release quite a few car communique modules that beef up high-precision positioning in keeping with Qualcomm’s three-D lifeless reckoning era and integrated Qianxun SI’s high-precision positioning carrier. For instance, AG55xQ sequence, the 5G&C-V2X car module with integrated multi-constellation GNSS (GPS/GLONASS/BeiDou/Galileo/QZSS) receiver, can beef up dual-frequency GNSS, high-precision RTK/PPE and GNSS/QDR built-in navigation answers in keeping with software necessities.
(3) Integration with Self reliant Riding Area Controllers
Integrating the high-precision positioning module into the independent using area controller can cut back information transmission, successfully shorten data lengthen, and enhance positioning accuracy. At the moment, automakers have begun to disassemble built-in navigation containers and combine GNSS modules and IMU modules into their very own area controllers.
At the moment, passenger automobiles principally use sub-meter-level built-in positioning modules, that have a low point of practical protection and don’t seem to be essential to combine into area controllers. When independent using evolves to L3+, L4/L5, high-precision built-in positioning modules should succeed in the centimeter point, and meet upper practical protection necessities, in order that they are able to be built-in into independent using area controllers. By means of then, the price of the built-in navigation and positioning module of each and every car shall be upper, which can also be the concern of primary OEMs and providers within the subsequent level.
With the adulthood of area controller era and the evolution of digital and electric structure, the combination of high-precision positioning devices and high-level independent using area controllers would possibly grow to be one of the most mainstream answers.
The chance of high-precision positioning marketplace is promising
In keeping with Clever Hooked up Automobile Generation Roadmap 2.0 launched in November 2020, the penetration charge of L2-L3 ICVs will succeed in 50% through 2025, and L4 ICVs will start to go into the marketplace and be to be had in sure eventualities and restricted spaces for business packages; through 2030, the penetration charge of L2-L3 ICVs will succeed in 70%, and L4 ICVs shall be broadly observed on expressways and a few city roads.
Supported through insurance policies, the meeting charge of L2 independent cars will keep growing, and the meeting charge of sub-meter-level built-in positioning modules will stay emerging; L3 and L4 independent cars will regularly unfold to the marketplace, and the shipments of centimeter-level built-in positioning modules with upper price will swell. Due to this fact, it may be predicted that the marketplace house for high-precision positioning in the following couple of years may be very large.
With the rise within the meeting charge of L2+ and L3 independent using purposes, the high-precision positioning marketplace has a promising prospect, and the trade shall be identified through buyers.
In October 2021, Asensing raised masses of thousands and thousands of RMB in Sequence C financing led through Sequoia China and joined through Matrix Companions, GL Ventures and different establishments. The price range shall be spent at the analysis and building of the next-generation practical protection high-precision positioning era, product design growth and capability development.
In October 2021, DAISCH finished the Pre-A spherical of financing, which was once concerned with Aosheng Capital. The raised price range shall be invested in growing new merchandise and processes, and bettering supply functions.
