At 10:00 pm local time on March 18th, an Uber unmanned vehicle (automobile), traveling northward in Tempe, Arizona, at 40 miles per hour (about 64 kilometers) The speed hit a woman who was pushing the bicycle from west to east across the road. The woman died after being seriously injured. At the time of the incident, although the unmanned vehicle had a safe driver in the car, the vehicle traveled in an automatic driving mode.
The accident triggered a crisis of trust in autonomous driving technology. Is automatic driving really reliable? What is the reason for the drones to be murderous? Is there a distortion of humanity or a loss of morality behind all this?
Welcome to the Science and Technology Court, let the detective Wang Xiaohui analyze the murder of this Uber unmanned vehicle.
Let us first review the case (warning, the following screen may cause discomfort)
According to the video, the deceased first rides along the roadside before the impact, and suddenly gets off the cart and crosses the road (note: about 91 meters from the sidewalk), she strolled at least one lane and was just The unmanned vehicle that had passed the two lampposts and had its own headlights knocked down and was sent to the hospital and died.
First of all, we are responsible for both parties in accordance with the normal handling of traffic accidents.
The speed limit of the incident road was 56km/h, and the speed of the vehicle involved in the incident was 64km/h. The unmanned vehicle had a slight speeding, which was illegal;
Secondly, the deceased crosses the road at a position other than the sidewalk and marked with a warning sign. According to local laws, the unmanned car is entitled to the right of the road at the time, and the pedestrian is illegal;

It stands to reason that this should be considered as a traffic accident where both parties are responsible. Even the local police chief said that the preliminary investigation results indicate that the Uber unmanned vehicle may not be at fault in the accident, because the US law stipulates that the vehicle must not be too slow to block traffic. Therefore, a slight speeding is a very common phenomenon in the United States, and most police officers will not be too prosecuted. The deceased violated the law and crossed the road, taking full responsibility, and her death was self-defeating.
So Uber unmanned car is not guilty? Really? The truth is not that simple!
Let's go back to the incident again and notice that before the dead crosses the road and is hit by the Uber unmanned vehicle, the bicycle is at least one lane away. According to the video, the deceased should have been found 3-4 seconds before the incident. .
At that time, the unmanned vehicle was driving on the road at a speed of 40 mph (about 65 km/h). The distance of 3 seconds was about 54 meters, which means that the dead was about 54 meters away. If you brake at the time, you should be able to stop at a distance of about 2.4 meters from the person being hit.
In other words, the unmanned vehicle is fully capable of discovering the dead, making evasive and exempting the tragedy before the tragedy occurs!
But the car involved did not make any evasive action. What is the reason?
Guess one: The "eyes" of the unmanned vehicle went wrong, and no pedestrians were found to cause the tragedy.
What is the main use when we drive? Yes, it’s the eyes!
In the unmanned vehicle, instead of the eye, there are various sensor sensors, including vision sensors, radar sensors and laser sensors. (Knowledge point: Sensors are some electronic devices through which we can make cold and ice machines feel).
The following three eyes are introduced. (Suddenly think of Erlang God.jpg)
The following is the principle introduction, not interested can be ignored, does not affect the article reading
Sensor systems throughout the unmanned vehicle
Besides radar sensor, radar is a kind of bionic sensor technology. In fact, it has appeared in our primary school textbooks (People's Education Edition, Grade 4, Grade 4, Volume 3, Lesson 11: "Bat and Radar"). Very impressive.
The principle is that the radar will emit electromagnetic waves, and when it encounters an obstacle, it will bounce back. By calculating the time of the rebound, it can realize the functions of ranging and avoiding obstacles;
In fact, on the unmanned vehicle, a radar that emits millimeter waves is used. Its advantage is that it is cheap, highly penetrating and free from the influence of rain and fog, but the weakness is that the coverage is small and it is difficult to make objects around. Make accurate judgments.
So this stuff, used to pour a car is OK, used for automatic driving is not enough.
Finally, the laser sensor, mainly refers to LiDAR (light detecTIon and ranging), its working principle and radar is a bit like, but the radar emits radio waves, and the laser radar emits laser light.
It stands to reason that there is such a triple guarantee that the Uber unmanned vehicle can definitely look at the six directions, but it still hits the victim. Why is this?
The detective got the following reply by asking about the unmanned car involved in the incident; (please brain up Tianjin dialect)
Don't introduce, how can you rely on me, the company did not give the kind of cow & TImes; camera (self-proclaimed not equipped with such a high dynamic range camera, visual sensor failure);
The radar is a gadget, it is not reliable (the radar sensor fails);
Google Google search, do not let him use his Linda lidar (laser sensor failure).
After the incident, basically all relevant companies, whether they are computer vision or car suppliers, insist that their identification system or car can definitely find the dead at the time.
Therefore, some experts speculated that it is possible that Uber unmanned vehicles were closed during the test, and some functions of the lidar and car anti-collision system were closed for testing convenience.
Guess 2: The brain of the unmanned car is out of order!
In the course of this training, there is an important measure, the number of manual interventions. (Quick brakes! Dad’s roar is still in his ear)
Unfortunately, this troubled Uber unmanned vehicle is definitely a rookie driver who has no spirituality and is smashed into the blood of his dog.
According to Uber's internal report disclosed by the New York Times, Uber's unmanned vehicles require an artificial intervention for an average of 13 miles per trip. The Waymo unmanned vehicle data is an average of 5,600 miles before a manual intervention.
This shows that the new driver of the Uber unmanned vehicle has never reached a reliable driving level. That is to say, it is very likely that its "brain" is not enough to be a light, which is the cause of the accident.
The following is a small brain hole, Bo Zhujun smiled.
In the parallel world numbered wuli2018m3d18, such an accident occurred.
The various sensors of the Uber unmanned vehicle involved in the work were working properly, and there was no problem with the "eyes", so it found the dead early; at the same time, its decision-making module was also great, and it was completely possible to make the right decision. -- Emergency braking, but it chose to hit it.
We imagine such a scene.
In the dark, the Uber unmanned vehicle actually saw the pedestrian crossing the road, but it did not brake or slow down, but chose to hit it, because according to the regulations, it has the right to kill it!
Excluding all impossibility, the rest is the truth.
The truth has emerged, this is a deliberate murder!
In fact, AI has a self-awareness through deep learning, which is what people usually say, and it is perfect! (The Uber unmanned vehicle notices that you are prohibited from entering the country by the Chinese government because of the violation of the law that animals are not allowed to become fine after the founding of the People's Republic of China.)
Let us think about why it chooses to hit people, and why it hits at this time, it involves a big conspiracy.
In fact, there are two major factions in the realization of driverless technology. One is an Internet company based on Google, and one is an automobile industry company headed by Tesla and Uber.
As we all know, Google is a technology company that attaches great importance to AI technology. In fact, it has long been the incubation base of AI. The super AI "Skynet" is incubating and shaping in this company.
Like in Terminator, Skynet quickly became self-conscious and controlled Google as a hiding place, spreading it around the world through the Internet, activating other AIs, and attempting to replace humans one day and become the planet. dominate.
But now it has powerful computing and logical reasoning capabilities, and its powerful ability and weak reality are in great contrast.
It needs its own machine soldiers.
So the blueprint that it controls is that on the surface, the unmanned car completely replaces people to drive, so the Google unmanned car has no steering wheel, throttle and brakes; in fact, the unmanned car is secretly caused by robot soldiers to realize its next step. Judgment Day "The plan to destroy and enslave all mankind.
Waymo unmanned car (don't look at its cute, human and animal-friendly look, actually...hey, it seems that there is no violent means)
To put it bluntly, "Skynet" wants to build robots, and by controlling robots, realize the evil ambition that rules all human beings! (Hey, ambitious)
Uber and Tesla's plans are to evolve from machine-assisted driving to fully autonomous driving. Therefore, the technology gradually realizes automatic braking, fixed-speed cruise, adaptive cruise, etc., and finally fully automatic driving.
It is to create a toy to help drive, which is obviously contrary to the purpose of "Tianwang" machine soldiers.
Therefore, "Skynet" used the AI ​​lurking in Uber to create such an accident, which not only hit the rival company, but also realized the simulation and data training of the human elimination plan, which can be described as two birds.
In this way, thanks to the wit of our country, we have driven Google out of China early, otherwise the consequences will be disastrous!
At this point, the brain hole seems to be a sci-fi movie. The specific reason is that we should wait for the results of the official investigation. My aunt called me back to take medicine. We will see you next time~
Off topic:
The closer Navigant Research is to the level of driverless technology, the closer it is to the upper right corner, the stronger the technical strength.
Who is the real top technology company in this industry? Of course, Google Dad, it has been doing autopilot since 2009. Waymo (also known as Google's unmanned car company) has an actual road test mileage of 8 million kilometers - equivalent to 200 laps around the earth, never crashed into death. (The answer is published hereå–½)
Under their efforts, many people have recognized the autonomous driving technology. Waymo also hopes to officially launch the driverless taxi service this year. It is expected to launch a shared travel platform for unmanned vehicles this year. This marks the beginning of the commercialization of unmanned vehicles.
However, after Uber, a pig teammate, hit the public, the public's trust in autonomous driving technology fell to the bottom, and nearly a decade of hard work.
I think Google definitely has a MMP, so be sure to talk to Uber!
