As early as 1968, in the sci-fi movie "Space Walk 200 1", human beings were full of yearning and exploration for artificial intelligence, and the most representative one was definitely the automatic driving of cars. # Highlights of digital technology #
Whether it was Tesla or other autonomous driving companies before. Ji feels more or less boring, either with incomplete functions or expensive costs, but after experiencing Huawei's automatic driving today. It can be said that automatic driving, which is closely related to most people's lives, is coming!
Huawei's first self-driving model this time is polar fox Alpha S, which cooperates with BAIC. You must have doubts. How could it be BAIC? In fact, Huawei's principle is, "Huawei is not a car, but a driver."
Therefore, many car companies will cooperate with Huawei in the future, and many models will be equipped with Huawei's ADS autopilot system. At present, Huawei has announced three manufacturers: BAIC, Chongqing Changan and Guangzhou Automobile.
This Huawei version of Speed Fox Alpha S is not much different from the normal version in appearance. Using crossover models, the spatial layout is the same as that of cars, and the ground clearance and car height are similar to those of SUVs.
However, you can obviously find that there are three laser radars on the front of the car, and around the whole car, you can find many cameras, and the details reveal a sense of technology.
This time, Huawei's ADS autopilot system is equipped with 34 sensors, 3 laser radars, 13 cameras, 6 millimeter-wave radars and 12 ultrasonic radars. Tucki P5 just said that it has the largest number of sensors in the industry, and it was surpassed in less than two days.
Before going on the road, Ji found it unnecessary to do other preparatory work. As long as the route is determined and the lever on the left side of the steering wheel is toggled twice, the vehicle will start point-to-point automatic driving.
Ji tried riding three times this time, day and night, with a total mileage of 36 kilometers. When the autopilot is fully started, the security officer's hand leaves the steering wheel, but he still keeps a virtual grip to ensure that he can visit at any time and ensure safety.
But obviously ADS didn't give the safety officer this chance. In all the test rides, the safety officer didn't intervene once. ADS handles all special situations by itself.
Ji was also very lucky to experience the night driving of Huawei ADS. You may not know that Tesla's autonomous driving will be less effective at night, because Tesla mainly uses cameras to identify, but the recognition rate of cameras at night will be affected. So this time I experienced the night driving of ADS, just to experience how good it is.
ADS system is equipped with lidar, because lidar is not affected by light intensity.
Therefore, during the experience, Ji did not feel the difference between driving at night and driving during the day. It can be said that Huawei ADS's automatic driving ability at night is definitely the first in the industry.
Domestic road conditions are very complicated all over the world. First of all, red, yellow and green are the most common things we encounter in our daily driving. Now many autonomous drivers can't recognize the traffic lights, including Tesla in China. All he can do is stop after the front car stops. If there is no car in front at the traffic light intersection, Tesla and other auxiliary driving systems in China can't recognize it, so they may drive directly.
This time, Huawei's ADS system can directly identify the camera and display it on the screen in the car, which is excellent in recognition accuracy and driving accuracy. However, at present, only the color of light can be displayed. If it is a red arrow or a green arrow, it is also considered as a traffic light, which is still a bit insufficient compared with a small amount of fsd tested by Tesla abroad.
When driving every day, I am most afraid of the takeaway brother with great mobility. He will always appear inadvertently. This is also the biggest challenge facing autonomous driving at present. After all, you can promise not to hit people, but you can't guarantee that people won't hit you! So running is very important, and hiding is equally important.
Huawei's advertisement is the most magical thing for Guo, and it automatically avoids it. Whether it is a takeaway brother who suddenly breaks in, or other vehicles that change lanes at will, they can avoid in advance.
However, "avoidance, avoidance" is definitely based on "concession". Huawei's ADS autopilot system mainly focuses on deceleration and avoidance. If it is inevitable, it will even stop completely.
In addition, Huawei's system is not a "dead brain". In some extreme cases, such as one lane, the front car illegally stops on the main road, the target lane is solid but there is no car, and the speed of the rear car does not decrease. At this time, ADS will choose safety among the mandatory topics of violation of regulations and safety, and will cross the solid line to complete overtaking.
If this happens to other auxiliary driving vehicles, the most likely situation is that the vehicle comes to a complete stop. If the rear vehicle does not brake in time, there will be a high probability of rear-end collision, which shows that Huawei's ADS autopilot system is very "smart".
If you have paid attention to the content of autonomous driving, you must have heard of "unprotected left turn". Simply put, at some intersections, there is only one green light at the intersection traffic lights to control the left turn and go straight. If you want to turn left at this time, you must find a gap in the oncoming traffic and get in before you can turn left. This situation is very difficult for some new drivers, let alone self-driving cars.
So at present, "unprotected left turn" is a difficult point for autonomous driving to overcome. This time, during the experience, Ji found that ADS had made an unprotected left turn at night and during the day, and it was very decisive. This must be because the software calculates the speed and direction of the opposite car very accurately. You can make an excellent unprotected left turn, so overtaking and changing lanes is no longer a problem.
When it comes to lane changing, ADS has a good logic, which is to slow down and change lanes. This is a very simple behavior for human driving, and it is indeed a very rare function in automatic driving. Other families' assisted driving, when changing lanes, will stop changing lanes if the target car is found to be following the car quickly.
ADS will slow down after this situation, and then change lanes after the next car passes. Ji Guo Jun is also curious, if there is no car in front, will it speed up lane change? Huawei's security officer said that the first logic of ADS is always security.
Huawei's ADS system is an "L2" responsible driving system based on the "L4" technical architecture. Simple but not comprehensive, it is an automatic driving system, but it needs to be used according to the logic of assisted driving, because it can ensure the safety of passengers to a higher degree. Therefore, Huawei's advertisements still need someone to sit in the driver's seat and pay attention to the road conditions. If there is an emergency, it will automatically remind you. You can intervene by yourself at any time.
So is Huawei's advertisement really perfect? Actually, it's not. In Kyrgyzstan's experience, in order to ensure safety, the braking logic of ADS is very radical, that is, in the face of the situation that some people can drive slowly, it will brake for safety.
Much like when Ji Gang started driving on the road, he was very cautious. It can't be said that this logic is wrong, but it is a bit different from the "old driver". In the process of chatting with Huawei engineers, Dayu also said that he would focus on optimizing this aspect and turn ADS into an old driver.
After experiencing Huawei's ADS autopilot, Ji Guojun was more expecting than shocked. Maybe one day, it will be possible to send Ji Guojun to the company, then run out to earn money, and then take Ji Guojun home at night to buy a car and earn more income.
However, with the progress of technology, the improvement of laws and regulations is also necessary. For example, let the vehicle drive automatically after drinking, is it drunk driving? Wait, this kind of question. If there is a good standard, I believe that after finishing the 996 work, the sleeping car will pull us home by itself, and this beautiful life is not far away from us.
