I said there seemed to be such a thing, so she asked me to help her.
Mecanum wheel
In fact, I believe that many friends will have this doubt after seeing the conference they are looking forward to. Is it true that you are floating on water? Is it true to turn in circles?
Especially at the press conference, many people questioned that its tires were not ordinary tires, but McNamham wheels. Indeed, if it is a McNamham wheel, it is much more convenient to move sideways and turn around in place than ordinary tires.
But that thing is not practical in daily life. What is the McNamun Wheel? My son's toy remote control car can realize in-situ U-turn and lateral movement.
There are many small rollers on the wheel, so it will realize many different functions, but this wheel is really not practical in our daily driving.
Yi Sifang technology
Then BYD looked up. If there is no McNamun wheel, is it impossible to turn around in place?
Brother Miao, let me talk to you. There is a very important one, called Yi Sifang Technology. The Yi Sifang released last time talked about a bunch of professional parameters, all of which are awesome things, all of which were summed up and applied to our life scenes.
First, four motors are driven independently, then extreme anti-skid and the other is body stability control. These three things are easy to say, but the fuel truck has been doing it for so many years. In fact, many of these technologies are in the hands of foreigners, especially those that always make people choke you.
So BYD can make a breakthrough in this field, which really gives us some confidence to some extent.
We won't be strangled in this respect in the future, and the technology of telex is faster than the original mechanical things.
Floating mode is used in emergencies.
So the response to reality is to look up at the scene given in its promotional film. One is floating mode, that is, you can drive directly from the water. Is this thing realistic?
As long as the car's sealing is good enough, and the key is good balance, then it can control the direction and have some power in the water, so it can really float.
But two days ago, I went to see their technical communication meeting. They say that this floating mode does not advise people to sail like a boat, but it is used for emergencies.
This is also reasonable. After all, it happens all the time now. If a heavy rain falls directly, the waterlogging in the city will be flooded. This function is really useful at this time, and it can be used to escape at critical times.
But when you use it at ordinary times, I think it's a bit exaggerated to say that you can easily go to the next sea or river.
In-situ u-turn mode
The second is to turn in circles. In this area, I even saw a friend say, can you walk sideways?
Of course, if you get on the McNamun, it is indeed possible to walk sideways, but we can also walk sideways with ordinary tires.
Because its four motors are driven independently, one motor can rotate in the forward direction and the other motor can rotate in the reverse direction, so that the car can rotate in situ.
But when doing so, this tire is sometimes a little unbearable. So you may use it, it will be more painful, and you can only say that it can be used in extreme cases.
High-speed puncture does not roll over
Third, it is also the most important one for me. I think it is the most practical one, which can control the stability of the car body when it has a flat tire at high speed.
Speaking of high-speed puncture, it is really a big killer in high-speed car accidents, with a high mortality rate. Especially if your speed is 120, if the front tire has a flat tire, many people can't help it, just roll over the guardrail and have an accident directly.
But as he said, when the car can reach the speed of 120 miles per hour, it doesn't matter whether it has a flat front tire or a flat rear tire.
BYD can interrupt the power output of a tire through its easy quartet technology, and even achieve negative torque.
You can really stabilize the car at this time. After all, this is mechanical transmission, and this reaction speed is incomparable.
How should domestic cars hit the high end?
Therefore, after the release of BYD's easy Sifang technology, it did give some subversive technologies.
Of course, at present, our domestic cars all want to hit the high end, but it is really impossible for you to hit the high end only by pile configuration.
Mercedes-Benz BMW can be high-end and Audi can be high-end. That's because people have brand precipitation, and people have brand precipitation for decades or even hundreds of years.
If it is a car without brand precipitation, it is really impossible to rely on pile configuration if you want to play high-end at once.
At present, our domestic cars are likely to reach the high end, just like BYD. I'm just looking forward to the price of U8 when it goes on the market.
abstract
If it is really more than 1 10,000, ordinary people can't stand it, then I really can only look up. If the price is set too low, it seems that I am sorry for the high-end word.
Of course, I also hope that this technology can be decentralized in the future, for example, in dynasty series, this technology can also be used. In this case, especially when the speed is 120 on the highway, if 200,000 to 300,000 cars have a flat tire on the highway, we can easily control it, which is really beneficial to us.
