Last month, this one thing: testing a Google robot car is on its way, after an intersection when a pedestrian suddenly appeared. Don't worry, the pedestrian did not happen, the correct response to the Google driverless cars, the system brakes, avoid the pedestrians in front of, perfect to serve as a "safe driver" role. While pedestrian intact, but Google cars have not been so lucky, because car drivers due to not hit the Google driverless car, a crash just happened.
Google has already put in a driverless car test on the road, it can be said the driverless cars are experts on traffic laws and regulations, set by their procedures in strict accordance with the law, never a situation of violation. But this setting sometimes can cause problems, because other human drivers of the car and sometimes not so "disciplined". In 2009, for example, when an unmanned vehicle in Google test when this is the case: after an intersection when the Google car suddenly broke down. Because it is set by the program: only at the junction on the left and right when the vehicles stopped at the corner of driverless cars will start the program. Junction a driver has slowly moved forward, however, did not stop completely, which led to Google car comes suddenly of paralysis.
Just Google the problems faced by a company. Driverless cars for the new, research shows that one of the biggest challenges faced by the new car, is how those not fully in accordance with the rules of traffic safety drivers share the road with human drivers.
Driverless car researcher Donald Norman, Director of design at the University of California laboratory, said: "now the real problem is that driverless cars are too concerned about security, they must learn to come when you need to be doing ' fierce ', and as to when they need to do, depending on the driving culture and habits in different regions.
Researchers predicted that when all cars are on the road in the era of driverless cars, traffic accidents and the casualties they cause will be greatly reduced. But the wide use of driverless cars, we also have many years of time, testers now also working to address many of the challenges faced by driverless cars, such as hacking, as well as some of the more practical issues, such as if a driverless cars on the highway and suddenly paralyzed to do.
Current development of self-driving cars also face a more immediate problem, which is how it can coexist with human drivers, and coordination. In fact, many car manufacturers have added some security accessibility to their cars, such as in the case of distance too close to remind drivers, or even stop programs that start automatically. In this context, Google in July this year, of Austin, Texas, and expand the scope of their unmanned vehicle testing, apart from them, other companies started to drone technology research, such as the Uber.
In actual road forms when Google's driverless car has been taken can be said to be "cautious" way, as far as possible avoid all hazardous situations, it can be said they are always with the maximum safe distance between themselves and other vehicles on the road.
Google driverless car tester Tom Supple around at Google's headquarters in Silicon Valley recently conducted a test, in an interview, he said: "Google driverless cars will always drive in accordance with traffic regulations. This way completely safe-sometimes to confuse other drivers on the road and even dissatisfaction, they'll think: ' this car do? the driver how so? ' "
Since the beginning of 2009 have been Google's driverless car has undergone 16 traffic accidents, most of which are rear. The company said, in an accident, the cause of the accident was human driver errors. Including the rear-end collision that occurred on August 20, Google disclosed the accident this morning from a to z. In order to avoid pedestrians in front, Google's driverless car slowed down, and then test the artificial slams on the brakes. But the car was hit from behind, and testers are slightly injured, was taken to the emergency room.
However Google's investigation on the accident report also showed that although testers put on the brakes to stop the car, was the right decision. However, if your car doesn't have a test but driverless cars alone to master control of the vehicle, then vehicle may not completely stop, but continues to move forward at low speed, and closer to the intersection, and then stop. After doing so can give more time and space. Whether it will be able to avoid the collision? for this problem, Google's statement is: this assumption could not speak clearly.
Google says, experienced in all accidents, should be borne by the Google car with a fully. This happened in August 2011, a Google car and another vehicle is in a moving motor vehicle collided. However, in this case, Google car being driven by testers for manual. In other words, in this case, mistakes are still human drivers, rather than the system.
Human and machine, looks hard to each other. Such as lane departure technique, this technique when drivers deviate from the current Lane, by beep or vibration of the steering wheel to remind the driver. This technology is good, but in 2012, the insurance industry's study, many researchers by surprise. Data show that vehicles equipped with this technology collision rate is slightly higher than even those vehicles without this technology.
Bill Windsor of Nationwide Insurance safety experts said that because of this warning system is too sensitive, drivers are likely to feel they are too annoying, so as to turn it off. This situation is not uncommon, and human behavior will always conflict with the behavior of the machine. When, for example when the car deviated from the current Lane, the car makes a sound, the reality is, the driver is consciously changing road and forget to use lights or no car behind, without the use of lights. In this case, automotive systems will still beep, this will allow drivers with no choice, they can only choose to turn off warning system.
Windsor shortly before the experience of human driving behavior conflicts with the overly complex automotive technology. He was driving his new Volvo on the road, this car is equipped with "adaptive cruise control" function. In the case of relatively simple traffic conditions, this technology can automatically adapt to the current speed.
But like Google driverless cars, this technology too strictly in accordance with the traffic regulations. While in motion, it will maintain a maximum safe distance with the car in front. This leads to a question: that other car in the next lane will suddenly "jump". Windsor said when using this function, there are always others trying to jump the car, and after closing success, it will open and the car distances, and then car stopper ... ... The cycle makes him uncomfortable.
Google driverless car engineered said Dmitri Dolgov, head of software Department, in charge of the driverless car projects, he learned the most important thing is that the human driver should learn to "don't be so stupid".
Google spokeswoman Courtney Hohne said driverless car projects, current unmanned vehicles the purpose of the test, just make the vehicle between the software and the human "smooth-running and excessive." For example, at the crossroads, when there are other car when slow-moving forward, driverless cars will not be paralyzed, but identified it as human drivers are used.
Professor of industrial and systems engineering at the University of Wisconsin, defensive driving and automation expert John Lee said that when humans when dealing with these situations, it is common practice to "eye contact". Through eye contact, people can exchange information, and decide who has a limited right of passage.</p>
He added: "how to make driverless car also has this ability to make eye contact?"
But Norman has different views. After many years of unmanned vehicle safety research, he believed that driverless cars will be popular in the future, because now that drivers are always will be distracted by other things, such as mobile phones as well as other in-car technology.
Sena Zorlu is a enterprise co-founder of Sunnyvale, California witnessed Google's driverless car accident recently, said she had also had a red light seen in mountain view Google's self-driving car. After the accident, she immediately took cell phone photos of the scene.
She will go to bed photos on Instagram, in an interview, she said: "under normal circumstances, I do not use mobile phones while driving. But the accident happened right next to me, so I seized the opportunity to capture the photo.
