The development of new energy vehicles has undergone profound changes at this stage. Not only has the market penetration rate of new energy vehicles increased steadily, but the "intelligence" of new energy vehicles has gradually become mainstream. According to data from the beginning of this year, the penetration rate of L2-level driving assistance and above of new power brands is basically above 70%, and the penetration rate of L2-level driving assistance and above of leading self-owned brands is above 30%. Obviously, an era of smart electric vehicles is coming, and the focus of competition in the second half of the competition for various manufacturers is here.
For the Jikrypton brand, which has been focusing on smart tags for a long time , its actions in this area are not fast compared with various "new forces". It is related to an important evolution in smart driving. On July 11, it was long overdue and officially pushed to the foreground, that is, the extremely high-speed NZP, the autonomous pilot assistance system.
The full name of Jikrypton NZP is Navigation ZEEKR Pilot. At this stage, it pays more attention to the performance of the system in highway or expressway scenarios.After the Jikrypton High-speed NZP is turned on, the vehicle can complete operations such as autonomous lane changes, autonomous up and down ramps, etc. based on the navigation route in closed roads such as expressways and expressways covered by the smart driving map, and achieve points in the area covered by the map. Point-to-point assisted driving.
For the "late" extremely high-speed NZP, is it too late for a good meal?
What is the basis of intelligent driving?
As a model of Jikrypton brand that pays attention to the intelligent driving experience at this stage, Jikrypton 001 and 009 are both equipped with the SuperVision system. In terms of hardware, the whole car is equipped with 7 8-megapixel cameras, 12 ultrasonic radars, and 1 millimeter-wave radar. The longest detection distance of the vehicle can reach 600 meters, which can realize 360° all-round perception. In terms of computing power chips, two 7nm Mobileye EyeQ5H chips are added, which not only have high efficiency, but also lower power consumption. And this configuration is also the standard hardware configuration that Jikrypton 001 and Jikrypton 009 have been carrying since their release.
This set of Mobileye's software and hardware is supported by front-view binocular and side-facing 8-megapixel cameras, and Mobileye's SFM algorithm, which generates 3D images through cross-triangulation of multiple cameras, and then recognizes objects. This is almost a It is a purely visual solution. It can establish a global real-time perspective, and it can achieve full coverage within a range of 200 meters. Make a distinction on the screen.
In addition to the level of the hardware itself, for high-level assisted driving, the precipitation of data is actually more important, which determines the adaptability of the system after it goes on the road. At present, Jikrypton High-speed NZP is established based on a huge automobile data set, including more than 200PB of real-world driving data collected around the world in the past 20 years, with a total of 16 million video clips. And this part of the data is also continuously accumulating, and the SuperVision system can continuously iterate and improve with data-driven algorithms.
The combination of hardware and software requires accurate road data as support, but compared to other autonomous navigation systems, the high-precision map of the NZP is more like an absolute assistant in more cases.According to the official, Jikrypton's NZP smart driving map has three major highlights: First, it has rich semantic data, including historical traffic speed data, etc. The system will continue to learn the driver's habits and update it in the NZP smart driving map.The second is high freshness. Compared with traditional solutions, the NZP smart driving map can support higher frequency map updates to ensure the freshness of information.In actual use, it can greatly reduce the system degradation and exit caused by the lack of maps, and improve the continuity of user experience.The third is high precision, up to centimeter level, meeting more precise trajectory planning and intelligent driving safety requirements.
The above theories and hardware and software can determine whether a high-level driving system is easy to use, and in order to ensure safety and efficiency to the greatest extent, Jikrypton also offers the "RSS Responsibility Sensitive Model", which integrates human "veteran drivers" for dangerous situations. The decision-making method is transformed into a mathematical model, and the model is used to verify whether the decision-making of intelligent driving is correct.
Extreme Krypton high-speed NZP real road experience
Under the current laws and regulations, Jikrypton's vision for intelligent driving functions is to create a "human-like" intelligent driving assistance system.The design concept of the technology is based on safety-oriented, in order to achieve the comfort and driving efficiency of the drivers and passengers. The active safety protection capability in assisted driving relieves the driver's driving fatigue.
Among them, "efficiency" and "safety" are a pair of game points in themselves, but this system actually has a more road display style than the former, and it has a stronger ability to judge and analyze surrounding traffic participants. The action of the car is also more like an "old driver", and the more humanized logic makes users more willing to use it in real car use, rather than just becoming a publicity gimmick on paper.
It should be noted that the extremely high-speed NZP version we experienced this time is still a test version of the system, and the ZEEKER OS system is still version 4.3, which is not the final version that will be pushed to users. In the future, it will most likely merge with ZEEKER The OS 5.0 system version was unveiled together, but its maturity is relatively high, and the general experience will not be much different from the final version. As the first area to cover this function, our experience location is also selected in Hangzhou this time, and the main experience road is the Qiushi Elevated Road.
Jikrypton High-speed NZP can realize full driving assistance from point A to point B based on high-precision maps and navigation on expressways and urban expressways. That is to say, after setting the destination on the system, in the area covered by the high-precision map, the car can automatically get on and off the high-speed ramp, merge into the traffic flow, overtake the slow car, avoid roadblocks, and follow the car safely. This experience is as you imagined. "Autopilot" is no different..
After setting up the navigation section, when the vehicle enters an area that meets the conditions, the car will display a function logo. Just confirm to activate it, and then you can properly release your hands for a long time of automatic cruise on the road. For traffic participants on the road, the car and machine can be quickly identified and rendered on the large screen, and the position accuracy is very high. Even in relatively complex environments such as dense traffic, rain and fog, the system can continue to run stably .
Under the cruising condition of the expressway, the NZP state of Jikrypton High Speed is relatively stable. At this time, you don’t need to turn the steering wheel at all. The system will automatically determine when you need to enter and exit the ramp, and will also judge whether the rear is safe or not, and then complete the lane change. . In fact, its main experience is not much different from general high-end driver assistance systems in terms of functions and capabilities, but the more important difference from them lies in the actions of planning routes, handling curves, and merging and overtaking.
When the speed of the vehicle in front is too slow during normal cruising, the system can judge whether to change lanes and overtake by judging the traffic conditions in the adjacent left lane. You can also manually dial the turn signal to change lanes. What can be clearly felt is that the timing of the extremely high-speed NZPP lane change is actually very radical. It does not require a long safety margin like the general automatic lane change, but the distance between the front and rear vehicles of the lanes on both sides. The requirements are very small, almost to the point of meeting every stitch, which is similar to our daily driving state, which is very "human".
So what do you do when you need to change lanes, but there is not enough space? Jikrypton High-speed NZP will even take the initiative to create opportunities to overtake in the game. It will try to cross over to the target lane to get "stuck", and will avoid or continue to merge depending on the reaction of the vehicle behind. When it comes to issues such as grasping the scale and selecting the best window in the lane change action, the system is almost no different from real driving.
The peak hours of expressways have always been the weakness of similar driving assistance systems. They are often stretched to deal with complex scenes such as merges, lane changes, and on-ramps under heavy traffic. System "strikes" are the norm. But also because of its gaming ability and more aggressive lane-changing strategies, the Jikrypton high-speed NZP also has such extreme scenarios that ordinary cars cannot handle. Sometimes you will feel that its performance is even more "fierce": it will pass behind the card. The parking space squeezes into the target lane a little bit, and occasionally it will make you feel a little worried, but in the end, it can always cut into the road that should go safely and efficiently.
The extremely high-speed NZP is actually relatively gentle during the entire lane change process, and its movements take into account the somatosensory of the driver and passengers to the greatest extent. However, small problems still exist. Because of the game strategy, the system will choose the timing of lane changes more frequently. As a result, the car will often make some meaningless lane changes. It is also more mechanically frequent when swinging, and the evolution of the comfort level and the choice of changing lanes is also the focus of future upgrades of this system.
While commuting on the expressway, there are occasional scenes of violent blocking by other vehicles. When encountering such a short-distance cross-cutting blockage, the vehicle control of the current solution will give priority to vigorous braking, and the action will be more obvious. of frustration. Although the Jikrypton high-speed NZP responds quickly to this situation, it does not brake suddenly and vigorously. It is very restrained and gentle on the braking force. A balance between safety and comfort has been achieved.
As for the ability to plan routes and judge the ability to merge into the main road lane, combined with road conditions, the Jikrypton Expressway NZP will gradually move from the road to the far right and slow down about 500 meters in advance. Compared with many car companies who change lanes 2 kilometers in advance, because the efficiency of lane changes is very high, there is no need to prepare for a long distance in advance, so it can accept less allowance.
