DVR
question we all often ask at least for themselves. The first self-government cars, is expected to appear in showrooms within five years. Their autonomous capacity is limited to high-speed road, which rarely seems to pedestrians and cyclists; You can count on your car. Although a clean way, it will go. When computer problems, such as road or bad weather, it will give you a bike.
The problem is that this change will not happen overnight.
The main advantage of independent technology to improve safety and reduce congestion. And yet, make this machine you to concentrate on work or correspondence that you want to do it. Although some rules initially forbidden to sleep behind the wheel, someone will surely try.
Audi tests have shown that it takes an average of 3-7 seconds – 10 – The fact that the driver cheered and took control of the situation, although all types of alerts. This means that engineers must be independent Audi could handle all situations, even during this time. This is important, because in 10 seconds can occur, especially when the car is moving at a speed exceeding 30 m / s.
This brings us to the DVR. If you really want to understand the challenges that engineers, program these machines, there’s no better way to illustrate the endless events that can occur on public roads. In the video below – a small selection of the giant video library to YouTube – the people fell on the bridge, cow dropping cars, tracks, tsunami and explode at home.
It is very impressive, the video drivers dodge the threat, and they deserve the benefit of innocence, when they fail. Autonomous cars meet the higher the bar, because every time they do not cope with the danger, it would be a serious blow to the reputation and potential legal liability model. The technique has advantages: they do not drink, do not crumble, not distracted and did not sleep. They ignore the idiots who were under them, and not succumb to the temptation to show what the two of you – the king of the road. With all this reaction is a computer many times greater than the speed of the human. They replace the human instincts – which often gives the wheel a fault – a certain set of rules.
One of the basic rule works for many unexpected situations on the road. Hit the brakes and try to avoid the subject is moving in the right way. But it works, you’re looking at the cows, Valya truck:
Or the guy who jumps off a bridge on the road and go somewhere:
Or when the truck goes under the asphalt:
The software car does not know what a cow – an obstacle to be avoided. But our joy, let DVR us to simulate the weight of the situations where the computer will make the right decision. But what do you do if a tsunami?
Or, when the building is falling apart (after being hit by car) and debris falling on the road?
or machine falls almost on the road, scary, but do not constitute a hazard to motorists?
or start a forest fire?
The idea that roads in the world – crazy unpredictable places where anything can happen. And they can not even be for pedestrians, cyclists, buses and taxis, which adds delays to the cart. How do you prepare for all situations?
Yes, after all.
You can use a computer simulation to teach and stand-alone software to avoid the craziest conditions imaginable, says Jürg Shlinkheyder manager of driver assistance systems in the Audi, but this approach is not the best: it is an enormous task, and You’ll never predict what would be a deadly situation. “While we are talking about a case, it is a problem. And you have to find them out.” In other words, you can not save the first automated vehicles that will flood or landslide.
This does not mean that a human driver to take the upper hand in this situation. If the car would be an unexpected and dangerous situation, he can send an alarm to the server, which will warn other cars territory, potentially saving lives. More importantly, this technique can be trained to: Sort Data means that the car is at least acknowledge this situation in the future. This information is maintained as a separate machine, and get the other cars, and (perhaps produced by competitors). That is, when the first tornado takes self-propelled vehicle, nothing can be done about it. But the second time you are done.
