A car equipped with cameras but without a driver, he'd better get used to it. U.S. giant Google announced on its official blog that his car that drives by itself has already traveled the length and breadth of California and accumulated over 200,000 miles. "They went down Lombard Street (famous for its slope and curves) in San Francisco, crossed the Golden Gate Bridge, crossed the road along the Pacific coast, and even went to Lake Tahoe," said Sebastian Thrun, an engineer at Google.
According to an article in The New York Times, the vehicles used by the company are the Toyota Prius and an Audi TT equipped with video cameras, radar scanner and a rooftop photograph the environment and transforms it into a three-dimensional map that allows the car to move.This system is still experimental "is made possible by Google's data centers, which can analyze huge amounts of information gathered by the cars," said Sebastian Thrun.
During these tests, the car is not in complete autonomy since a driver is still sitting behind the wheel in order to regain control if required. Moreover, the vehicle is preceded by a normal car he opened the road by collecting data allowing it to move.
Experiences multiply
Since 1968 and the early adventures of Herbie, the race car saga The Ladybug leading alone, reality catches up gradually fiction. Many attempts have been made, particularly in the context of competition.It is in the context of the challenge organized by DARPA, U.S. agency in charge of advanced research projects for the Defense, Sebastian Thrun, an engineer from Google, was tested for the first time his autonomous car.
In 2008, at CES, the world fair of technology in Las Vegas, General Motors unveiled a prototype smart car able to move or carry out the perfect niche, while detecting other vehicles to avoid accidents."This is not science fiction," had said on that occasion Larry Burns, vice president of Research and Development Group, noting that most of these technologies for unmanned vehicles existed.
Volkswagen, the Passat CC is already equipped device to "detect dangerous situations" and a parking aid that makes itself the steering maneuver.
Security and traffic control
For Google, the development of an unmanned vehicle is in the spirit that presided over the founding of the group in 1998 by Larry Page and Sergey Brin: "They wanted to help solve major problems through technology. And one of the major problems we are working today is the safety and economy cars.Our goal is to help avoid traffic accidents, free up time and reduce carbon emissions by fundamentally changing the use of the car. "
Applications put forward in the development of autonomous vehicles have focused primarily on safety. The goal is to allow the car to act only in critical situations and to overcome the inattention of the driver. Thus, the Volvo S60 has she an automatic braking system that detects pedestrians. "Our innovative technology is programmed to track the very configuration of the pedestrian movement and also calculate whether he (or she) will cut into the path of the vehicle. The system can detect pedestrians from a height of 80 cm, that is to say as children, "said in a statement Thomas Broberg, safety expert at Volvo Cars.
More innovative still, the concept of autonomous cars could also be used in traffic control. Google also mentions the "road trains" still vague idea that, after the release of the group, is expected to "transform carpooling and reduce car use." In Europe, a concept is already approaching developed since 2009 through the SARTRE project (Safe Road Trains for the Environment) funded by the European Commission. The goal is to establish, within ten years, convoys of automated vehicles. People who use the busiest roads enter these convoys led by a lead car. Therefore, they will pass on autopilot and their owners will take care of something else.When the user arrives at his destination, he will leave the queue of vehicles and automated resume control of his car.
This type of trains will be tested in 2011. It will soon be possible to go to work while driving his car … with no hands.
