The biggest highlight of the new car is the perfect inheritance of the dual-motor version of the high-order intelligent driving system, which sets off a new round of intelligent driving offensive with higher cost performance.
In the early stage of listing, Bian Xiao deeply experienced the city NCA function of OITA 1 1 single motor version in Shenzhen. Its subversive user experience has made most media people shine.
First of all, Aouita 1 1 is equipped with AVATRANS intelligent navigation system based on Huawei's ADS intelligent driving solution. The system consists of AVATRUST extrasensory system and AVATRUTH supercomputing system, which can realize high-speed and urban NCA intelligent driving and navigation assistance, intelligent parking in parking lot, and cover all travel scenarios.
The test drive route is * * * 1 1km, which involves a series of difficult scenes such as traffic jam, ramp entrance and exit, unprotected left turn, ghost probe avoidance and navigation lane change. Aouita 1 1, relying on the leading software and hardware level, runs the whole course in half an hour and drives actively all the time. He is an old driver with precise and smooth functions.
In the past few years, urban intelligent driving navigation assistance has become a battlefield for high-end brands. From Tesla's high-profile opening of the FSD bate version of the North American internal test, to Xpeng Motors' opening of the China market, and then to the other side's failure to find the North, many car companies vowed that it would be a blow, but the reality is that the urban traffic scene is complex and changeable, and those vows have already passed the baptism of time.
From this point of view, Aouita 1 1, which has the ability of urban NCA intelligent driving and navigation assistance, is very precious. Of course, this goal cannot be achieved without the strong technical capabilities of Huawei and Changan Automobile.
Parts 1: avatrust extrasensory system
The Aouita 1 1 single motor version adopts HI Huawei's full-stack intelligent vehicle-mounted solution, equipped with AVATRANS intelligent navigation system based on Huawei's ADS intelligent driving solution, and 34 sensors including 3 laser radars, 6 millimeter-wave radars, 13 high-definition cameras and 12 ultrasonic radars. On the hardware level, it is consistent with the Aouita 1 1 dual-motor version, achieving the best performance and the strongest intelligent driving at the same level.
Aouita 1 1 Intelligent driver assistance system has been strictly configured and designed in terms of the number, types and performance of sensors.
First of all, in terms of lidar, Aouita 1 1 is the first SUV with three lidar schemes in the industry. Three lidar sensors are installed in front of the vehicle and at the left and right A-pillars respectively, which can form 300 visual field coverage.
The visual field of our eyes is 200 under normal circumstances, and with the help of rearview mirrors, the visual field can reach about 260. The 3-lidar sensing scheme of Aouita 1 1 is wider than that observed by human driving.
From the perspective of automobile industry, at present, most automobile enterprises are equipped with 1 or 2 lidar scheme, which has a blind spot for high-precision perception of lateral and lateral backward direction.
Comparatively speaking, the coverage of Aouita 1 1 laser radar is higher, which makes Aouita 1 1 know the oncoming vehicles in the rear earlier when turning left and right, and predict the trajectory and intention of oncoming vehicles earlier, so as to make a more calm judgment.
For example, in the same scene, under the condition that a certain model has no side lidar, the data reported to the computer is that there is an incoming car 20 meters behind the side, and the accuracy error is plus or minus 10 meter. At this time, it is difficult for the computer to judge the specific location of the incoming car, and it is impossible to make command decisions such as changing lanes and overtaking. The experience conveyed to the driver is that the system is hesitant and unresponsive.
Aouita 1 1 is equipped with lateral laser radar, and the detection accuracy of the same scene can reach centimeter level, so the computer can more accurately identify the distance and driving intention of the vehicles behind, make decisive decisions and have a better user experience.
Of course, the induction scheme of Aouita 1 1 has been fully upgraded.
In terms of millimeter-wave radar, six millimeter-wave radars located at the front and rear of the vehicle can provide all-round physical distance information for AVATRUST supercomputer system.
Moreover, the millimeter-wave radar installed in the middle and long distance behind the vehicle has a maximum detection distance of 265,438+00 meters, which provides extremely accurate moving speed measurement data, so that the AVATRUST supercomputer system can quickly make lane change decisions according to the calculation of relative speed and avoid rear-end collision.
Of course, even with so many kinds of radars, the intelligent driving assistance system of vehicles still needs the addition of visual cameras to achieve real "seeing clearly". Therefore, Aouita 1 1 also installed 13 high-definition cameras in different parts of the vehicle. It can observe the road speed limit signs, adjust its own speed, and can also detect the changes of traffic lights from a distance, so as to accurately predict and follow comfortably.
In addition to the common object recognition, visual cameras also need to cope with the perception ability in dim scenes at night.
For this reason, based on Huawei's deep technology accumulation in the field of moving images, Aouita and Huawei have customized cameras with large aperture and large photosensitive sensors. Compared with mainstream solutions in the industry, the photosensitive performance has improved by 30%, and it can also bring more excellent and stable image quality in low-light scenes.
In addition, considering the scenes such as crossing a tunnel, the camera may be temporarily overexposed (temporary blindness). Aouita 1 1 also introduces HDR high dynamic range algorithm to ensure that the camera has the ability to record a wider range of light and dark information, which is also a way to improve the reliability and stability of the intelligent driving assistance system.
The last link is deep integration. Camera, millimeter wave radar, ultrasonic radar and laser radar do not work independently, but they can cooperate with each other.
For example, radar can not only detect the distance of objects, but also improve the focusing speed of cameras. It can accelerate the definition of the visual camera at the moment of imaging, so the camera can always ensure high-definition imaging and improve the reliability and stability of the intelligent driving assistance system.
According to Aouita's introduction, with high-standard sensors, they are deeply integrated with each other, realizing the integration of parking system and control system and realizing a real intelligent driving platform. Do you look like a martial artist? He got through the second pulse of Ren Du.
Part II: AVATRUTH Supercomputing System.
AVATRUTH supercomputing system is a set of driving software that really looks like an old driver.
Aouita 1 1 is equipped with the first anthropomorphic interactive game algorithm in the industry. Oita said that the driver's interactive logic in driving is to watch while driving, rather than wait until you are optimistic. With the addition of game algorithms, NCA can be as flexible as human beings and drive as warmly as human beings.
For example, at many unprotected left-turn intersections, if there are oncoming vehicles, generally for safety reasons, the driver will stop and wait for the straight vehicles to pass before completing the left turn. However, the reality is that the through train will speed up in front of you only when you stop and wait. This logic is safe, but inefficient. At this time, drivers often take over impatiently.
The game algorithm of OITA 1 1 is to detect the opposite vehicle, observe tentatively while walking, and accelerate directly if the target vehicle slows down to let the vehicle pass; If another car accelerates into the intersection, stop and give way quickly.
The driving logic of the game algorithm is just like human drivers trying to figure out each other's driving intentions. In the process of decision-making while walking, they express their intentions with physical dynamics and compete psychologically with each other's vehicles to achieve a perfect balance between safety and efficiency.
In one day's experience, Aouita 1 1 safely and efficiently solved complex scenes such as unprotected left turn, right turn, ramp merging, and congested road sections. The shock of experience can be described as subversion. This is also the first time that Bian Xiao felt thinking, temperature and character from machinery.
In addition to the game algorithm, Aouita 1 1 also adopts the first training method in the industry to learn from old drivers.
Massive data trains deep learning algorithms, but Huawei believes that it should be driven not only by data, but also by correct data. Just like primary school students doing homework, but it is equally important to be guided by correct answers.
At present, most self-driving car companies in the industry have adopted crowdsourcing data collection training, and the training materials are complex, including many wrong driving behaviors. Huawei, on the other hand, invited many experienced old drivers to make correct answers on the road, so that the system algorithm could train and learn the behavior driving of old drivers, learn the correct decision, and make the driving logic more human.
On the whole, Aouita 1 1 divides travel scenes into unprotected left and right turns, traffic lights countdown (accurate prediction and comfortable follow-up) in urban NCA scenes, traffic jams (seemingly calm sea surface, in fact, undercurrents surge), tunnel traffic (changes in light and shade will temporarily blind eyes), and ghost probe avoidance (T-junction probes, unpredictable pedestrian behavior, and. There are dozens of small scenes, such as high success rate), large curvature cornering (the center of the ramp is stable, and there is no need to correct it), navigation lane change, overtaking lane change (fast decision-making during high-speed driving), and then software training and optimization are carried out for each small scene.
In the actual experience, the NCA system in the city actively drives the whole journey 1 1 km on the same day, realizing the perfect closed loop of point A-B. The whole experience process is gentle and fast, and it is alert and safe.
Obieta said: Up to now, Obieta 1 1 Expressway NCA has covered 280 cities in China, covering nearly 300,000 kilometers of expressways and urban structured roads.
The data shows that the Aouta 1 1 expressway NCA has traveled 4 153 13 kilometers, an increase of130% compared with February; APA Smart Parking has been called 126973 times, an increase of 88% compared with February; The maximum speed of a bicycle using high-speed NCA is 337km. It can be seen that this system is widely welcomed by users, usable, easy to use, and is a real "spot" rather than "futures" intelligent drive.
In addition, since March 2023, Aouita has officially opened the user test drive experience assisted by NCA intelligent driving navigation in Shanghai and Shenzhen, and Guangzhou and Chongqing will also open the experience soon. NCA push will be conducted for users in Shanghai, Guangzhou, Shenzhen and Chongqing. By then, OITA 1 1 will become a full-scene high-order intelligent driving production car in most cities in China.
With the successful landing of NCA in urban areas, Aouita 1 1 has improved the core scene layout in the field of advanced intelligent driving, and realized the full scene coverage of high-speed, urban areas and parking.
Part III: Summary:
In the past few years, the global automobile industry is experiencing the biggest change in history. The high-end SUV market with a starting price of more than 300,000 yuan has changed from the rule of traditional automobile companies to the list of new forces. Behind this, the competition pattern of luxury car market is no longer as stable as in the past, and consumers' evaluation criteria for luxury cars are quietly changing.
In my opinion, Aouita 1 1 is a new product tailored for this change.
The first is research and development. The OITA brand is backed by Changan Automobile, Huawei and Contemporary Ampere Technology Co., Ltd., with industry-leading vehicle development capability, global front-row battery research and development capability and global front-row intelligent full-stack development capability respectively. With Qi Xin's concerted efforts, we gathered huge talents and funds to build OITA, which made the brand have certain advantages at the beginning of its establishment.
Secondly, in terms of product experience, intellectualization is a more grand industrial change after electrification, which happens to be one of the core advantages of Aouita 1 1. Thanks to Huawei's Hi blessing, Aouita 1 1 took the lead in realizing NCA's large-scale landing in urban areas with "game algorithm" and "humanoid driving algorithm" when companies such as Weixiaolikun were still in deep technical difficulties.
From the perspective of industry competition, Tesla, Tucki, Zhiji and other driver assistance hardware need to be installed at a higher price, and the software delivery is far away. Aouita 1 1 comes standard with ADS hardware, and the intelligent software and hardware of the single-motor version are exactly the same as those of the dual-motor version, which opens a new era of intelligent driving for all.
In addition, Aouita 1 1 should be the first car company in China that can use a full set of advanced NCA software systems on the delivery date, so users don't have to write blank checks or wait.
Smart blessing makes the sales of OITA 1 1 go up all the way. By March 2, 2023, the cumulative delivery volume of Aouta 1 1 has exceeded 4,000 units. In the first three weeks of March (March1-March 19), a total of 1443 sets were insured, and China brand high-end (over 300,000) pure electric SUV ranked first in three weeks. The launch of single-motor models is expected to push sales to a new height.
