Ever wondered how self-driving cars of Google see the world? Here's everything you need to know

The last reorganization in Google brings many changes and changes the way we have been looking at various projects of Google, not blurred by Android or look shows how important they all are to the company. One of these, Google X, which includes self-driving cars also will become a subsidiary of the alphabet, and is no longer a part of Google.

Self-driving cars has been the pet project of Google for quite some time, and now under alphabet, the company is known for having started work on the design of the cars. Over the past year, the company has been testing several cars without driver and I have seen some prototypes and first experiences of users taking a walk.

However, he never thought the car without driver knows he has to take a turn or there is a cyclist on the right or the traffic light is red. Recently, project manager Chris Self Drive car Urmson was a Ted Talk and explained exactly how the car works and improvements so far.

Let's get into the car head.

First, the car trying to figure out exactly where in the world using the map and sensor data. Now depending on what you see, Google adds a layer of how the world looks. In the image below, the purple boxes are other vehicles on the road. You can see the cyclist in red and come cones. Also, knowing your environment, the car also predicts what will happen next.

Well, what you saw is how the car is thinking of a vehicle, but this process becomes very complex as in real life there are many vehicles as well as pedestrians, cyclists, trucks, etc., on the road. The car has to predict what each object you plan to do. Moreover, after predicting the car then decide on how to respond, what path to follow, whether to go slow or fast, and so on.

In the city streets are all new challenges and great certainty. There will be pedestrians crossing the road, traffic lights, pedestrian crossings and so on. The vehicle is also taught to deal with construction. There cones that will force the car to move in agreement, considering the exact location of the building is carried out. Moreover, it will also be showing people crossing or walking in the construction zone.

What happens if a police van stops the car? Yes, the car has been taught that the flashing light on top of the car means that it is not just a car, which is actually a police officer. In addition, the car also taught to distinguish from other vehicles of a school bus, which will appear as an orange box and know to be treated differently.

All this looks and sounds simple, but driving also involves human behavior. So, if a rider puts his arm asking the car to compromise and make room for him / her, and then stop the vehicle and let it change lanes and so on. Similarly, it will be known when asked to stop by a police officer and continue as soon as the official signals to be.

Now, this is all one can possibly expect, but there are several other things that might be new. "So a couple of months ago, our cars were driving through the mountains, and this is what we found. This is a woman in a power wheelchair chasing a duck in circles along the way. (Laughter ) It turns out that there is no place in the DMV that tells you how to deal with it manually, but our cars were able to find that, slow down and drive safely, "Urmson said. Similarly, it also slows down when watching a bird fly.

It's advanced technology and there is always the question whether to pave their way to the market, but now Urmson confidence in technology by making it on the market. But when? "It's hard to say, because it is a very complicated problem, but these are my two children. My oldest son is 11, and that means that in four and a half years, to be able to get your license. My team and I are committed to ensure that does not happen, "which rang.

Urmson also explains how the car would be incredibly useful in many ways. For example, he cites example of Steve, who is visually impaired and spends hours on public transport and asking friends and family to take him to his workplace, but a car auto driving will end all the problems by reducing the time to mere 30 minutes. On the other hand, another driver who owns a Porsche also found the car very convenient.

Speaking of safety, the report adds that human drivers can make mistakes that lead to traffic accidents which is once every 100,000 miles on America. On the other hand, a self-driving system makes decisions about 10 times per second, in order of magnitude, which is about 1000 times per mile, he said.

What he did not say is the latest incident involving Google self-driving, which left four wounded car. The three employees of Google on board complained of minor whiplash, were taken to hospital and cleared to return to work after the July 01 crash, Google said last month. This certainly raises questions as the car is ready to take on the roads, yet. In an accident of a car without a driver, which is responsible for accidents or injury? While innovation is a big step forward in the world of technological advances, driverless cars still leave many questions unanswered.
