Driverless car beats Berlin traffic

Industry news

It can talk, see, drive and no longer needs a human being to control it by remote. The car of the future - completely computer-controlled - is on the streets of Berlin.

Since June 2011, researchers from the city's Free University have been testing their autonomous vehicle around the German capital.

This Volkswagen Passat has been driving itself around Berlin since June 2011, and it hasn't had a accident yet, thanks to a 360-degree laser scanner on top of the car, a GPS system and other sensors to monitor the surrounding traffic.Labs assistant Paul Czerwionka adjusts the 360 degree laser scanner on top of the Free University of Berlin autonomous car.The driverless Passat passes the famous Brandenburg Gate, with nobody on board; nobody human, that is.

It maneuvres through traffic on its own using a sophisticated combination of computer, electronics and a precision satellite navigation system in the boot, a camera in the front, and laser scanners on the roof and around the front and rear bumpers.

Raul Rojas, the head of the university's research group for artificial intelligence, said on Tuesday: “The car can recognise other cars on the road, pedestrians, buildings and trees as far as 70 metres away - and even see if the traffic lights ahead are red or green and react accordingly.

“In fact, the car's recognition and reaction to its environment is much faster than a human's.”

The scientists have worked on their research car, a Volkswagen Passat worth €400 000 ($551,800) with lots of built-in special technology, for four years.

Several other groups have also been working on such technology recently, notably Google, which has been testing a robotic Toyota Prius in Nevada.

Ferdinand Dudenhoeffer, a professor for automotive economics at the University of Duisburg-Essen, said: “There's a big trend for completely computer-controlled cars - many companies and research centres in several countries are working on it and it is hard to say, who's got the most-developed vehicle at the moment.”

Dudenhoeffer estimated that with the technology advances, it could only take another decade for the fully automatic cars to start becoming available for consumers.

“Even today's cars are often partially computer-controlled, for example when it comes to parking or emergency brakes.”

However, he said, besides the technological issues, the legal challenges would be another issue that needed to be regulated: “Who will be responsible when there's an accident - the owner or the passenger of the computer-controlled car or the company that produced it?”

“However, all in all, one can definitely say that computer-controlled cars will be much safer than human drivers,” Dudenhoeffer said. “Especially if you keep in mind that most of today's accidents are caused by human error.”

In Berlin, the university researchers received a special permit from the city's security and safety controllers in June to use it in regular traffic - under the condition that a safety driver sits behind the steering wheel, even if he doesn't touch anything.

The team has also been allowed to let the car run without anybody aboard on a special testing ground.

Rojas said: “This kind of technology is the future of mobility.

However, he was more conservative than Dudenhoeffer, saying that it could be 30-40 years before they became available to the average consumer.

The key to the automobile's intelligence is in the way the computer program runs.

Rojas explained: “In the beginning with had trouble with the robotic driving style of the car; but we've worked on the programming and now its driving style is as smooth as a human being.”

Rojas estimates that once the technology - specifically the sensors - becomes less expensive, such cars will eventually conquer the roads.

“It is similar to the beginnings of the computers - 40 years ago, only research labs could afford computers, now everybody is walking around with a computer in his pocket.”

Ideally, the car will respond to orders by remote control, for example on an iPad or an iPhone. With a click or a touch, the passenger can call the car to his personal location and then order the car to drop him off at his desired destination.

“This kind of car is actually perfect for car sharing,” said Rojas. “There will be no more need for owning a car - once the automobile has dropped off its passenger it will drive on to the next passenger.” - Sapa-AP
