Google tests cars without a driver!




by Christophe » 10/10/10, 13:02

And this over thousands of km, hey no, it's not April 1st ...

Google tests cars that drive themselves.

Self-drive car The cars have done thousands of miles, Google says

Engineers at Google have tested a self-driving car on the streets of California, the company has announced.

The cars use video cameras mounted on the roof, radar sensors and a laser range finder to "see" other traffic, software engineer Sebastian Thrun said.

They remain manned at all times by a trained driver ready to take control as well as by a software expert.

Google hopes the cars can eventually help reduce road traffic and cut the number of accidents.

In a posting on the company's official blog, Mr Thrun said the self-driven cars had so far covered 140,000 miles on the road.

They have crossed San Francisco's iconic Golden Gate bridge, negotiated the city's famous sloping streets, driven between Google offices, and made it around Lake Tahoe in one piece.

It is a huge challenge in software and design to adapt to all real situations on the road and the behavior of other drivers sometimes quite aggressive, if we respect the road rules too much, for example, by braking too much or not turning yellow red !!.
have been largely incident-free, apart from one bump when the car was reportedly hit from behind at a traffic light ......
the World Health Organization which shows that more than 1.2 million people are killed each year on the roads, and said that number could and should be reduced.


Once developed, tested, it will be a real revolution, slow to establish, but inevitable, with almost automatic trains of cars and much less aggressive driving !!
We gain half a second of driver reaction, and the possibility of being warned at long distance at crossings, informed of all vehicles with their GPS and speed, even before the appearance of a problem.

On motorways, all automated with no surprises, the speed may be higher, especially in the USA, slower !!

At first, it was a US military project !!
http://www.pcw.co.uk/v3/news/2271265/go ... nomous-car
Google hired a highly respected development team to build the automated vehicle's systems, including Chris Urmson leader of the winning 2007 DARPA Urban Challenge team and Mike Montemerlo, the software head of the team that won the 2005 DARPA Grand Challenge. Also included is Anthony Levandowski, who built the world's first autonomous motorcycle as well as a modified Prius that delivered pizza without a person inside .....
DARPA, which is funded by the US Department of Defense, is funded the challenges to investigate automating military vehicles, particularly for mundane resupply work. The organization has said it would like a quarter of all military vehicles to be automated by 2030, and the first prototypes have already been built.

http://www.rttnews.com/Content/GeneralN ... Id=1441193
But the objectives are much more than military and google could be a winner in this artificial intelligence software project, as for its search engine, which amazes me every time I ask a question to google which delivers incredible information on the formidable internet labyrinth !!
Much more impressive than micro !!
The main protagonist behind the project is Stanford Artificial Intelligence Laboratory's Sebastian Thrun. He is an engineer with Google and was one of the co-inventors of Street View.

Other engineers involved include Chris Urmson, Mike Montemerlo, and Anthony Levandowski. Levandowski is credited with having made the world's first autonomous motorcycle that participated in a DARPA Grand Challenge, and is also the architect of the "modified Prius that delivered pizza without a person inside."

Google said, "one of the big problems we're working on today is car safety and efficiency." Exuding optimism, the company stresed "technology's ability to advance society, which is why we have pushed so hard to improve the capabilities of self-driving cars beyond where they are today."

Finally someone who gets started ... since the time we expected that!
For those who have seen it, it is very impressive, "trains" of vehicles traveling at 130 km / h not even 1m away! Thus the following vehicles benefit from the suction of the leading vehicle ...
Still, it scares the hell if everyone has to brake ...

Still, it scares the hell if everyone has to brake ...

The electronics brake at the microsecond (40microns of travel!), Not at half a second or at best at 0,3s like an ordinary conductor at 40m / s (144Km / h) or 12 to 20m lost to react !!
Also, the fear should only exist when the electronics crash, or a software bug !!!
Reasons to test and double the electronics and the computer, but the man will be less reliable in the long term !!

Yes and yet I would prefer not to run the train all the way : Cheesy: Nothing will force me to stick in a convoy, it is especially at the beginning that there will be accidents ...

Other than that it's clear, we are statistically less reliable than electronics, ... so as long as it works. Why? Should I feel reassured? : Mrgreen: : Mrgreen: : Mrgreen:

If I have a relative confidence in the electronics, I have a little less in the human being, what about a "takeover" of a driver in the convoy? Sudden mechanical failure? A change in road condition (snow, ice, aquaplanning, fog ... what about the preceding convoy in the event of fog and jamming of the radio waves through which the vehicles will communicate ...)

This is all part of the development, but little by little the artificial intelligence software will be able to get there with the help of the increase in the power of the microprocessors and the size of the memories !!
Translating one language correctly into another is more complex and we're starting to do it (not on current google).

For "snow, ice, aquaplanning, fog ..." a solution is to move away much more vehicles, much slower than currently where current drivers always go too quickly unaware of the real ice, real ice rink (and which force you to darken like them so as not to disrupt traffic by forcing them to brake too dangerously), aquaplaning is rare except excessive speed and steering wheel errors and the fog will be resolved by communication between vehicles.
Communication between vehicles can use several frequencies and systems, such as ultrasound, infrared, redundant to the point of being unscrambled at a short distance (5 to 100m).
This system by forcing drivers who "take over" to wait for an authorization and more safety in their driving will make progress in safety as well as respecting the 2 seconds of distance between vehicles, never respected, even if desired, because otherwise we are immediately doubled, and we wait our turn indefinitely !!

In my opinion, it is not easy, but everything will be resolved by progress and better driver education.

So nothing extraordinary on the car, but better than for an ordinary driver in visibility, and that software where google is very strong !!

It seems that there is a system embedded in a car which allows to recognize road signs, in particular speed limits:
you drive quietly, and suddenly the car brakes on its own and does not exceed 50 km / h because you have come across a limit sign at 50 without having seen it.

There would also be a GPS system connected to a database which identifies the signs, their precise positioning and what they say.

Has anyone heard of these systems?
