Navigate on Autopilot, Will it reverse the autonomous driving situation?

Share

Yesterday, Elon Musk posted a very important message via Twitter:

Navigate on Autopilot 001 - Navigate on Autopilot, Will it reverse the autonomous driving situation?

 

What is Drive on Navigation?

Tesla made a blog yesterday to introduce Drive on Nagivation (It can be seen that the official has also given enough attention), but the name and Elon’s name on Twitter was changed to Navigate on Autopilot. This adjustment has changed very well.

I have to say that the endless stream of misuse of Autopilot has made Tesla very restrained. I use the vernacular to describe what is going on: on the highway, enter the destination, enable Navigate on Autopilot, and then it will take over the steering wheel, the electric door, the brakes, perform all driving operations until the vehicle exits the highway, but remember that the driver needs to monitor the whole process.

Below is the official demo video.

 

Here, the basic answer is what Navigate on Autopilot. But it led to another problem. I said that Autopilot will take over the steering wheel, but the driver holds the steering wheel in the video. What is going on? We will answer later.

The second question: How does Tesla see driving safety?

This is a very big problem and it is very interesting. Because in the public’s perception, Tesla has developed R&D routes for new functions by collecting road test data from vehicles sold around the world in the past few years. It is clearly “taking users as mice, ignoring life safety, and being ignorant and fearless.” It’s a large autopilot industry experiment…

The Tesla Q3 earnings conference was very interesting. The opening ceremony was of course Elon Musk. The first executive to speak after him was Tesla Chief Security Engineer Madan Gopal.

First provide a basic background:As of today, Tesla is developing and delivering a total of three models: Model S/X/3, all of which have acquired US IIHS/NHTSA and European E-NCAP. A five-star rating from a top security rating agency.

However, Model 3 is not the same as the two big brothers. Madan Gopal said that since 2011, a total of 943 cars have received the NHTSA’s five-star safety rating, while Model 3 is the one with the lowest probability of injury in the 943.

The next words are crucial:

I want to say a little more, how do we view driving safety? This has always been Elon's main concern. You can see how the Model 3 responds to a positive center impact, which was not part of the new car crash test rating. I just want to say that we will go beyond the new car crash rating to ensure the safety of the car, which is very important to us.

Once again, Tesla is developing two platforms (Model S/X is the same platform), and based on the second platform, the most secure of the 943 five-star safety models. Elon was previously on Twitter explain that the Model 3’s body design is definitely simpler, and most of the quality differences stem from the higher safety than other models.

Safety-First. This expression looks very official, most car companies will talk, and Tesla does have model safety support.

The third question: Why is Autopilot iteratively updated?

The third question: Autopilot This issue is the most critical issue in this paper, because Tesla can iteratively update Autopilot, which is closely related to the vehicle OTA mechanism. This makes Tesla face all kinds of criticisms such as taking the user as a mouse, taking life as a play, listing the function without development, and helping users develop functions later. On the other hand, it is Tesla that goes beyond NHTSA for safe crash testing and wins the safest model. This is too split.

I tried to answer Tesla’s logic about why the driver’s drive system was iteratively updated to the autopilot system instead of developing the self-driving car directly in one step. Elon actually explained it. There have been several incidents caused by misuse of Autopilot.

Navigate on Autopilot 005 - Navigate on Autopilot, Will it reverse the autonomous driving situation?

Our current assisted driving system has been proven to provide better safety than human driving, with one-third of the world's average on the road fatality rate (NHTSA's statistical report). Even if we retreat 10,000 steps, our system is only 1% better than labor, so we can save 12,000 lives in the 1.2 million people killed in a car accident in a year. So I think if you have such a technology to improve security, it is morally wrong just to hide it because of public pressure or legal prosecution.

Navigate on Autopilot 006 - Navigate on Autopilot, Will it reverse the autonomous driving situation?

We will see an endless stream of Tesla crashes in the newspapers, but on YouTube, there are also a large number of car owners uploading cases using Autopilot to hedge. On the whole, Autopilot assists humans to drive cars, driving safer and higher and higher, which is the driving force behind Autopilot’s iterative update.

This explanation seems to be consistent with the logic of developing a five-star safety model above, that is, always committed to providing the safest car for the user.

Fourth question: What is the next challenge for Autopilot?

From the user’s point of view, Autopilot is becoming smarter and it is taking over everything and automating all driving operations. If you follow the International Society of Automotive Engineers’ classification of autonomous driving, Navigate on Autopilot is a standard L3 automatic driving system.

The L3-class automatic driving system, that is, all driving operations are performed by the system, but humans are also on standby to take over the vehicle in time when the system requests it.

NHTSA and SAE Autopilot Rating Table - Navigate on Autopilot, Will it reverse the autonomous driving situation?

Let’s compare the other levels: L1, L2 require the driver to concentrate on driving the car, the system is only auxiliary, the responsible body is the driver; and L4, L5 do not need the driver to participate in driving the car, the system is completely taken over, the responsible body It is the system.

L3 alone, the system sometimes takes over driving completely, and sometimes it is helpless. It also requires the driver to completely relax and chase the sleep, and sometimes concentrate on driving the car. The responsible subject also switches back and forth… See here you can understand someone say why L3 is against humanity?

Engineers’ thinking levels are often limited, and the challenges that exist in real-life scenarios are not considered. This is why many car companies such as Car and Home, General Motors, Volvo, Ford, etc. have announced the abandonment of the development of the L3-class automatic driving system, and in turn to promote the development of L2 and L4 automatic driving systems. Although the technical challenge of L4 is even greater, its responsibility is very clear, avoiding the endless troubles of the L3 system.

However, is the Audi A8 not the first car in the world to be equipped with an L3 autopilot system? Isn’t Audi afraid of hidden dangers?

Navigate on Autopilot 008 - Navigate on Autopilot, Will it reverse the autonomous driving situation?

On this issue, I can only say that this is the victory of Audi’s marketing department. Audi’s publicity in the field of autonomous driving has surpassed Tesla and Waymo. After all, the former only carries the assisted driving system, while Waymo’s automatic driving, the car has not yet been mass produced.

In fact, how can Audi not know the hidden dangers of L3? The A8’s automatic driving system is like this: when the traffic is congested and the speed is reduced to below 60km/h, the system will take over the vehicle and perform all driving operations; once it is above 60km/h, the system will be alerted to exit.

When you drive the Audi A8, when can you maintain a long-term speed of less than 60km/h? So, this is a very narrow application. Conversely, can Tesla not do autopilots with a speed of less than 60km/h? Can’t GM do it?

This is the success of Audi’s marketing department.

Continue to say Tesla, will Tesla Autopilot transition from L2 to L4? This is a complex problem that depends on computer science, ultra-large-scale big data feeding AI deep neural networks, sensor performance, chip computing power and other fields. But in any case, Tesla has another problem that remains unresolved – redundant systems.

What is a redundant system? Redundant systems are designed to increase the reliability of the system by two or more sets of identical, relatively independent configurations. As an example, the automatic driving system drives the car to fail during the driving process, and another independent braking system will immediately intervene to ensure the stable operation of the system.

As an example, the automatic driving system drives the car to fail during the driving process, and another independent braking system will immediately intervene to ensure the stable operation of the system.

Today’s Tesla models are not equipped with a complete redundant system for autonomous vehicles.Automotive electronics engineers have commented that the architecture that supports the autopilot system typically has two backup (redundant) designs for power and bus communication, covering at least steering, braking, and power drives. In fact, the above can be collectively referred to as power and actuator redundancy, in addition to the need for awareness, positioning and power redundancy. Tesla did not do much work in these areas.

On the technical level, however, we see that Tesla is pushing the Navigate on Autopilot feature, although there is already a user experience that is not good enough, but don’t forget that Tesla Autopilot 2.0 hardware is “almost unavailable” It took only one year to iterate to experience the best driver assistance system on the market.

According to Stuart Bowers, vice president of engineering at Autopilot, Tesla plans to implement autonomous driving technology in the next 6-12 months. What is the future 6-12 months? Power, redundancy and fault-tolerant design Tesla AI chips with automatic driving levels will be available in volume production – Tesla is quickly removing the barriers to autonomous driving.

How does Natisla solve the problem that the L3-class automatic driving responsibility is not clear, and the L4-level automatic driving has no redundant design?

At the Q2 earnings conference, Stuart Bowers, vice president of engineering at Autopilot, was asked an interesting concept when asked “when the technology from the east coast of the United States to the west coast a”:

it's taking those same kind of features we've been working on, probably deploying them in the form of active safety features. That's like a thing we can do already to understand like – use this rich understanding of the environment to actually try to keep you safer.

Realize the automatic driving system in the form of active safety functions?

Active safety function, which is different from passive safety functions such as seat belts, airbags, and car body energy absorption structure, mainly refers to ABS, ESP, lane departure warning… and auxiliary driving systems such as Autopilot and General SuperCruise are active. security function.

So it is necessary to understand this: Tesla is confident that the autopilot technology will be implemented in the next 6-12 months, but the current Tesla vehicles do not have redundant systems. Is that not to push to the user first?

No, Tesla’s product philosophy on Autopilot is that once the security of the system has improved, it is immediately pushed to all users. The system will become more and more intelligent until automatic driving is achieved. But even if Autopilot evolved into the autopilot phase, users must continue to monitor the surrounding traffic, because Autopilot doesn’t have a redundant system yet—now you know why the official demo video driver at the beginning of the article can’t get out of the steering wheel with his hands?

You may ask, the vehicle can drive automatically, why should I hold the steering wheel? This question CBS host Gayle King asked Elon, his answer is that Autopilot, which supports autonomous driving, is ten times more secure than human driving.

It can be said that starting from Autopilot V9.0, the autopilot field has ushered in a big variable  interestingly, at the recent Alphabet earnings conference, Alphabet CFO Ruth Porat revealed that the Waymo autopilot car has started to operate. How to cover the world from several cities is one of the main challenges facing Waymo.

The good show has just begun.
