Chapter 1474: Live test!

After Lin Yu announced that he would conduct a live broadcast test, the live broadcast room became more heated again.
Anyway, as soon as the words "live test" came out, the press conference was immediately full of program effects.
Whether it is a successful live test or a live test rollover, it will definitely be full of topics!
For fans and sunspots of Shenhua and Stefer Motors, this is a once-in-a-lifetime opportunity.
Switched to the test site on the big screen, and first carried out acupuncture test and rolling test in the battery research and development center of Stefer Motors.
In the acupuncture test, acupuncture comparison results of three power batteries were made: the ternary lithium battery burned violently during the acupuncture process, and the surface temperature exceeded 500 degrees; the lithium iron phosphate battery had no open flame and smoke during the puncture process. , The surface temperature is 200~400 degrees; while the blade battery is unnamed fire, smokeless, and the surface temperature is 30~60 degrees!
Then came the rolling test. The entire blade battery was removed from a K1 prototype on the spot, and then the PDU distribution box on the battery pack was removed and placed on the side for data collection and testing. The upper layer was raised again. The 28 blade batteries that came out were removed, leaving only the lower 150 blade batteries, forming a plane.
Then, put this plane in the depression of the road, and use a pure electric heavy truck with a counterweight and a total weight of 46 tons to repeatedly roll it!
Although during the rolling process, the battery surface was slightly dented and recovered through the lens, but after the pure electric heavy truck was driven away, the battery pack was still intact after a close observation!
Of course, this intact means that its appearance is not damaged, but if you look closely, the aluminum plate on the top layer is still slightly deformed.
But this kind of deformation has no effect on the performance of the battery cell. From the test data, it can be seen that the single cell voltage, total voltage, insulation resistance and battery temperature of the battery remain the same as before the test, and there is almost no change.
Immediately afterwards, the engineers on site put the blade battery back on the Jifeng K1 again. After the installation, the car was successfully driven away!
This test stunned the audience in the live broadcast room.
Because it is hard to believe that Blade Battery can do this level!
In fact, at the press conference, Lin Yu already introduced the performance parameters of different batteries, but the response was relatively flat.
The main reason is that other new energy vehicle manufacturers are too good at blowing up their own technology. The battery technology has also gone through several rounds of "boasting competition". The audience heard someone boasting about their own battery technology. , I don't catch a cold anymore.
Even if Stefer started with batteries, the audience is a little bit disbelieved.
But the on-site test passed the intuitive picture, so the audience had to believe it!
In the past, one of the concerns of new energy vehicles is that the stability of the battery is not reliable. Once a car accident occurs, it is easy to catch fire and spontaneously ignite.
Many small battery cars use relatively inferior ternary lithium batteries, which often catch fire and spontaneously burn out in just a few seconds, posing a major fire hazard. Even a regular battery will catch fire and ignite after a violent collision.
Putting it on a battery car may be relatively less harmful. As long as you don’t ignite spontaneously in the elevator, it will not be a big problem in the open air, at least it will not kill people. But new energy vehicles are different. Once a collision occurs, the owner may be stunned, and it is too late to escape. The rapid fire of the battery may directly cremate the owner in one step.
There have been many cases of electric vehicles igniting spontaneously and cremating their owners after a crash in foreign countries. Although there are fewer cases in China, they have also occurred.
If the battery problem is not resolved, what if the crash test of the electric vehicle is done well? The car shell is able to withstand and absorb energy, but the battery burns up, isn't it still for nothing?
But after watching the needle test and rolling test of the blade battery, all the audience have a very intuitive understanding of the safety of this battery.
Coupled with Stefer Automobile's good reputation for crash safety, the safety of this Polar K1 has become quite trustworthy.
The wind direction on the barrage has undergone some changes.
"Awesome. Compared with the ternary lithium battery, the blade battery is simply crushed! The improvement of safety is more important than anything else. It doesn't make much sense to run more than a few dozen kilometers. It is serious to save your life at the critical moment!"
"Stefer's technology is indeed excellent, this is not black. If it weren't for the brand to pull the hips, the price would not be so low."
"But the real test has only begun now. This test of Blade Battery must have been done many times. The conditions of each test are basically the same, and it can be guaranteed that there will be no problems. Therefore, there is no rollover in the live broadcast. But the automatic driving is different. The road conditions of the test were different. What if the smart car system suddenly got stuck due to a program problem? It’s hard to say."
"Maybe some people will be dispatched in advance to evacuate the vehicles and pedestrians on the road? It would be too confident to just test on the road. If the recording is good, the live broadcast will not be able to save it!"
After the successful test of the Blade Battery, the audience's concerns shifted to Shenhua's autonomous driving technology.
Lin Yu did not, like other manufacturers, blew for five minutes after one test was completed before entering the next test, but directly entered the test of autonomous driving technology.
"In order for everyone to see the effects of autonomous driving technology more clearly and intuitively, we will turn off the voice assistant prompts during the test. Of course, if you become the owners of Jifeng K1 in the future, I strongly recommend you to try AEEIS’ artificial intelligence voice package will definitely bring you a different surprise."
Lin Yu's words caused a burst of laughter.
"Hahaha, thank you, I have experienced it! The keyboard has been smashed by me. Fortunately, I haven't bought a car yet, otherwise the loss would be great if I smashed the car!"
"Nonsense, I have been driving K1 in the game for a long time, and now I feel calm and I will never get angry again."
In the barrage of ridicule, the test of autonomous driving officially began.
This live broadcast has three different camera positions. One is placed in the back seat of the vehicle and directly shoots the steering wheel, the central control screen and the road ahead; the other is a drone, which is suspended in the upper room of the vehicle, which is a bit like a holographic image. The same, overhead shots of the body and the road; the last one is arranged on the side of some complicated roads and shot from the perspective of the observer.
Soon, the tester drove to the test section, and then turned on automatic driving.
The audience immediately discovered that the situation of this autonomous driving is exactly the same as in the game!
There are two main differences: the first is that the size of the central control screen in reality is slightly smaller than that of the game. This is because the game is displayed on a monitor after all, and the field of view is small. In fact, reality and the actual viewing in the game are more sensitive. It is similar; secondly, there is no voice in the BB, which is pure driving.
This is also understandable. After all, if AEEIS is released, everyone's attention will be on AEEIS, and they will no longer pay attention to the performance of autonomous driving. The supporting role is really too good for the show.
At the beginning, it was just ordinary changes of lanes, lanes, following cars, etc. The safety officer did not speak, and the road conditions were not too complicated, so there is nothing to say, and other autonomous driving technologies can basically do it.
But soon, the road conditions became complicated!
After completing an unprotected left turn, the barrage was amazed.
Because unprotected left turn is a relatively difficult point in automatic driving, it means that automatic driving must be able to recognize traffic lights, identify zebra crossings, pedestrians, and avoid straight vehicles. As long as there is a mistake in one link, it will cause no problems. Failure to protect the left turn.
In the process of automatic driving, as long as the vehicle does not avoid the far straight vehicle or fails to avoid the pedestrian, the safety officer must intervene in the driving as soon as possible, and then the automatic driving will fail.
However, K1 is safe and smooth in the process of completing an unprotected left turn. It not only accurately recognizes the traffic lights at the intersection, avoids straight vehicles and pedestrians, but also is always smooth and smooth during the driving process, giving people a sense of calmness. a feeling of.
But the barrage hasn't had time to smash it, K1 has come to a more complicated section.
The road itself is not very spacious, there are still a row of cars and a large number of battery cars parked on the side of the road, many pedestrians riding bicycles and battery cars or takeaway brothers reciprocating through it, and even riding into the middle of the motor lane.
The cars on the opposite side are also squeezing this way. Sometimes, in order to avoid pedestrians, they have to cross the center line and meet the other cars on very narrow roads.
The barrage was shocked.
"Energy ahead!"
"Fuck, such a complicated road section? Crazy? Not to mention autopilot, I feel my blood pressure is up!"
"This kind of road can also be driven? And it is more stable than mine?"
"It's quite easy to do... Although the autopilot reminds the driver to take over, the driver just ignores it, and it really passed!"
"I'm going, that takeaway guy is crazy? A battery car overtakes the car from the blind spot from the rear right perspective and then stops directly? If I drive, I will have rolled down the car window and scolded him!"
"Oh, if you are so hurried and panicked, you don't see the fish takeaway brother at first glance. The fish takeaway brothers are very calm."
"Ghost probes can recognize it, which is awesome! And the big screen is indeed real-time modeling. Cars, bicycles and pedestrians can be accurately distinguished. The more dangerous ones will be marked in red, which is indeed better than humans. clear!"
"Yes, in fact, even if you don't use autopilot, just glance at this central control screen once in a while, it can be helpful for driving, and you can better grasp the road conditions!"
After crossing this complicated section, UU Kanshu www.uukanshu.com Jifeng K1 drove on a section with relatively few vehicles, and the speed increased again.
In the case of complex urban road conditions throughout the entire journey, Jifeng K1 has been hovering at 10KMH for a long time, but after the road conditions permit, it can drive up to 50KMH.
Compared with other autopilot models, this speed is already very fast. Because autonomous driving must first ensure safety, other vehicles dare not drive so fast.
Although it is still slower than human driving, it has to be said that the Pole Front K1's automatic driving will be safer, there will be no risky behaviors, and acceleration and deceleration are very smooth, and there will be no sudden sudden changes. The situation with one foot of accelerator or one foot of brake.
This is obviously more comfortable for the passengers in the car, and it is not prone to motion sickness. It is a huge improvement in the riding experience!
