Chapter 2137 Too strong performance is also a problem
However, with the help of technical staff, the lidar detection screen was quickly brought out and slow-played.
Please see, these are several test simulated obstacles we have placed on the road. Their sizes range from ten centimeters to one centimeter. Our test is to see whether these test simulated obstacles can reach a speed of 100 kilometers per hour.
Can be detected and discovered.
Under Zhou Yonghui's introduction, everyone stared at the big screen. Soon a simulated obstacle was detected and selected, then the second, then the third, and the fourth.
Finally, all the simulated obstacles were identified, and a burst of warm applause broke out.
But at this time, Zhang Jun raised a question that worried him.
"Is it really necessary to apply such fine detection accuracy to autonomous driving? Not all road conditions will be so good. If these tiny objects or potholes are recognized and avoided, what should the car do?
The driving experience of the passengers in the car may not be that good."
Hearing Zhang Jun's question, everyone thought for a moment and nodded. Indeed, if it is a road with poor road conditions, even if it is a road with a long history, it is inevitable that there will be some potholes and potholes.
Some rocks and dirt, is it really necessary to avoid these things?
Of course it's best to avoid them, but if you avoid these tiny objects in such a mundane way, with constant steering, acceleration and deceleration, the riding experience of the passengers in the car will definitely be poor.
So after hearing this question, Zhou Yonghui smiled and shook his head and said: "We have already thought of the question you asked.
In fact, this is a problem that needs to be dealt with in autonomous driving technology. What we are doing now is the performance test of lidar. From this point of view, the higher the accuracy and resolution that lidar can detect, the better.
As for whether to use it or not, this is a question that needs to be considered in terms of autonomous driving technology.
In other words, it can be used without it, but it cannot be done without. We can use system algorithms to perform subsequent upgrades and optimizations on these problems, but the hardware cannot, so we must improve the performance of the hardware as much as possible from the beginning.
Since you mentioned this issue, let me first introduce to you and everyone how we handle this aspect.
Although these tiny objects of one or two centimeters, potholes have no impact on vehicle driving and will not cause any damage to vehicle tires.
But this matter is not absolute. Some of these tiny objects will still have a very large impact on the driving of the vehicle, and even cause car crashes and fatalities.
For example, one or two centimeters of iron nails, sharp objects, etc., once these objects are crushed by the tires of high-speed vehicles, they are likely to cause tire bursts. Vehicles traveling at high speeds are not very stable and may burst suddenly.
Tires may cause the vehicle to change direction, get stuck on other vehicles or road guardrails, or even run off the road, run off a cliff, etc.
Even a sudden tire blowout may cause the vehicle to roll over, etc., which can be said to be very dangerous.
With such fine detection capabilities, we can perform corresponding processing on the autonomous driving system. For example, actively avoid detected sharp objects. In this way, we can greatly reduce the occurrence of sharp objects puncturing vehicle tires.
.
For most ordinary tiny objects, we can selectively remove them. For example, we can filter them directly and ignore their existence. Or, if conditions permit, we can avoid them softly and avoid crushing them as much as possible.
Small objects, etc.
For some roads with poor road conditions, we can plan driving routes in a targeted manner to avoid large obstacles as much as possible. We have already applied this technology and related algorithms to our work on the moon.
The intelligent lunar surface patrol and exploration vehicle 'Wangshu' is on board."
While Zhou Yonghui was speaking, the test was still going on. At this time, the speed of the test vehicle had reached 120 kilometers. When driving at such a speed on the highway, you didn't seem to feel anything. But as bystanders, everyone
I can finally feel how fast the car travels at 120 kilometers.
Not only that, on the entire test road, there is also a test vehicle driving from the opposite direction, also at a speed of 120 kilometers per hour. This also means that if the two test vehicles do not slow down, they will instantly encounter each other.
The relative speed can reach 240 kilometers, which is a very terrifying speed.
At the same time, there are many drones hovering in the sky. Whether these objects can be identified at such a fast speed also makes everyone full of expectations.
Identify it, identify it!
As everyone exclaimed, the screen showed the test drive heading this way, as well as some drones in the sky.
This distance is estimated to be four hundred meters.
Three hundred and ninety-one meters. Zhou Yonghui glanced at the data on the screen and replied.
marvelous!
Being able to detect it at such a long distance at such a speed really surprised everyone, and they all praised it.
Wu Hao looked at the speeding vehicles on the road, then smiled and waved his hand: "Okay, I'll stop here."
Come on, the 140-kilometer test has not continued yet. Zhang Jun, who was watching happily, suddenly became unhappy when he heard what he said.
In response to this, Wu Hao said angrily: "I still have work to do, so stop playing.
This result is already very impressive, there is no point in testing it anymore and it will waste time.”
After saying that, Wu Hao turned to Zhou Yonghui and said: "Okay, let's stop the test here. We have seen everything we should see."
Zhou Yonghui nodded when he heard this, and then called on the technicians to start testing.
Wu Hao, as for Wu Hao, glanced at the test vehicle that was gradually slowing down on the test road, and then asked Zhou Yonghui: "When will this lidar be put into market?"
Upon hearing his question, Zhou Yonghui immediately turned to look at him and replied: "Currently, the relevant testing work for this lidar technology has been completed. Logically speaking, we can launch it into the market at any time.
But, we plan to wait first.”
Wait? When Wu Hao heard this, he looked at Zhou Yonghui with a puzzled look. Not only him, but Zhang Jun and the others also looked at Zhou Yonghui. They were a little curious as to why such a good technology was not launched for application, but had to wait.
Yes, wait. Zhou Yonghui nodded and explained: "We feel it would be too much of a loss if we just sell hardware equipment, so we plan to launch it together with our new generation of autonomous driving technology for bundled sales.
And itself, our new generation of autonomous driving technology is also optimized and upgraded based on the new generation of lidar and other technologies, so the software and hardware are better matched, and the performance will naturally be stronger."
