When talking about unmanned driving, we must first be clear about what is truly "unmanned driving"?

The terms "driverless", "autonomous", and "driver assistance" are often confused.

In fact, they represent different levels of autonomous driving technology.

Driver assistance technologies are currently being deployed in production vehicles and are often referred to as advanced driver assistance systems (ADAS).

There are currently as many as 20 types of such technologies, including automatic navigation systems, Internet of Vehicles, adaptive cruise control, lane departure warning systems, lane keeping systems, front collision warning systems, night vision systems, adaptive light control, pedestrian protection systems, etc., all of which can be called driver assistance technologies.

The primary ADAS is mainly passive alarms, and when the vehicle detects a potential danger, it will send an alarm to alert the driver to abnormal vehicle or road conditions.

With the latest ADAS technology, active intervention has become more common.

The best in the industry is currently the Israeli company Mobileye, whose ADAS products account for 75% of the global market share.

It is called "autonomous driving" if it is a little more powerful than driving assistance.

Autonomous driving has more stringent technical and vehicle performance requirements than driver assistance.

The core of this is the "false false negative rate" in the "target recognition algorithm".

The false false negative rate is also the most important metric to distinguish between driver assistance and autonomous driving.

For example, there is an AEB (Autonomous Emergency Braking) in autonomous driving, and if you always brake misbrake, it will pose a threat to the safety of the vehicle, and the false alarm rate is equally important. Because of a false report, the car may be destroyed and people will die.

In 2017, Tesla had a car accident, and the self-driving vehicle crashed into a horizontal trailer, which is a false report.

In addition to target recognition algorithms, high-precision map planning is of course also very important.

There is no high-precision map, and it is very common to guide you to the gutter (funny face).

In addition, the fusion of vision and radar is also an important option for autonomous driving, which has been explained before, so I will not repeat it here.

Finally, there is unmanned driving.

Unmanned driving = full autonomous driving, which means that in unmanned driving mode, the task of driving is completely handed over to the AI system.

There is no steering wheel and no throttle in driverless vehicles, there is only 1 start/stop button, click the "start" button when you get in the car, tell the system the destination, then the car will carry you to the destination you want to go.

As for the intermediate driving process, how to go, and how fast to drive, the system has the final say. All you need to do is sleep in the car or have sex with your girlfriend.

Google's driverless car is a driverless car in the true sense of the word.

Of course, there is still a long way to go in terms of functionality.

And the driverless car driven by Li Yanhong is, strictly speaking, a car with advanced autonomous driving functions.

Why doesn't whiteness work?

Because whiteness has not developed a complete AI system, and the fusion of vision and radar is not in place.

Speaking of which, I have to mention that there is a more awesome existence in unmanned driving, called "people-oriented man-machine collaborative driving";

Ever played a violent motorcycle?

It's just that someone in the back is ready to scare you, and you throw a stuffy stick and beat him half to death first.

The AI technology that integrates people and vehicles is so witty.

For example, when encountering a bear child or an old bad guy rowing a car, the vehicle will automatically warn, and if the warning is not heard, it will automatically drive away from the parking space, and he will "sneer" at him with a face of oil before leaving.

Geely Chief Engineer Tao Yang waited for an hour in the Tianyi No. 58 exhibition hall, and finally waited for the young man who had become famous in the domestic science and technology industry for more than a year.

"Hello Mr. Han, I have admired the name for a long time...... "The chief engineer didn't have a little arrogance, and took the initiative to step forward and stretch out his hand.

Han Yi was also smiling, took the other party's hand and said, "The potter is too polite......"

After a few words of greeting, Han Yixu took the other party's arm and walked towards the temporary lounge in the exhibition hall.

The six girls standing next to the glossy display case kept their eyes on their young boss while introducing the products to the guests.

An 8-point beauty, while turning her elbow to the side, then covered her mouth with her hand and whispered: "Hey, our boss is so handsome." ”

The girl who was whispered, under the skirt was a pair of slender beautiful legs, at this time the beautiful eyes slanted, and asked with deep meaning: "Are you drooling?"

The 8-point beauty first froze, and soon understood, her face was as red as a boiled shrimp, she looked left and right, and saw that no one noticed them, so she squeaked her with her hand, "You big perverted woman......"

In the lounge here, the chief engineer of Geely got straight to the point, "I believe that Yao Gong has already told Mr. Han about the situation, right?"

We are very sincere, if Mr. Han is willing, we will go all out to cooperate with you. ”

It has been decided that Han Yi does not have a mother-in-law, and now time waits for no one, and it is necessary to let all manufacturers see the power of Tianyi's unmanned driving during the expo.

Going back and selling it in a bundled way, forcing those car manufacturers to have to purchase their light detection sensors, two in one!

"It's okay to cooperate, but I want you to start preparing now, and by noon tomorrow at the latest, the comprehensive field test will begin. The tentative target is the Lujiazui CBD commercial area and the inner ring elevated. ”

"Ah...... In Lu Jiazui?" Geely's chief engineer, including the two assistants, was surprised, "Mr. Han, this is ...... Wouldn't that be too presumptuous?"

Han Yi smiled: "You don't care about this. Since I said it, I must be sure. ”

"That ......" Tao Yang hesitated for a moment, and finally gritted his teeth and agreed, "Okay! I'm sure Mr. Han won't let me down." ”

............

At half past four in the afternoon, 11 engineers came to Geely's headquarters, along with a car for driverless modification, the 2019 vPro SUV.

Not as reluctant as Tao Yang promised, Geely's senior management almost jumped up with joy when they heard that Tianyi was going to use their car to do an unmanned comprehensive test.

Let's not talk about whether Tianyi can be completely unmanned like Google, even if it can't be done, what can it do?

At that time, the world's attention will be focused on Geely, and their cars will definitely sell well, the stock will rise sharply, and there will be countless benefits.

So while sending engineers to China Shipping urgently, Geely's headquarters has already begun to build momentum for tomorrow's publicity.

Dozens of engineers from Geely and Tianyi here unloaded the vPro SUV in the room provided by the international exhibition hall for modification.

It's a complex project that involves a myriad of sensors and system fusion;

Tianyi's chief engineer Surier, as well as Yuda and Yuer, all participated.

They mainly optimized the algorithm recognition, and moved the system and big data computing that Tianyi had not had time to test to this vPro SUV.

Algorithm recognition is the basis for the realization of unmanned driving, if you can't correctly perceive the surrounding environment, then the next cognition, decision-making and control are all in the air.

By 10 o'clock in the evening, the algorithm recognition had been basically completed, and the engineers of both sides began to install various types of sensors in various parts.

Han Yi called Suriel out.

The two of them walked from Dongdaemun to the road.

At night, the road is full of traffic, and the car lights meet with the street lights to form a sea of light.

Han Yi walked for a while before asking, "Do you think you're sure?"

Surier "thought" for a while before saying: "It's not a big problem, but if you want to reach the level of a blockbuster, algorithm recognition, systems, ADAS and other aspects are not yet in place." ”

"So what do you say?"

Surier said directly: "By implanting a back door in the system, I can take over the vehicle directly in case of an accident and ensure that nothing goes wrong." ”

Surreel's proposal was something Han Yi had thought of a long time ago.

This kind of thing can only succeed, not fail.

Unmanned driving itself is now on the cusp, let alone crashing, and the slightest friction will be drowned in saliva. What indirectly affects Tianyi's reputation.

It just felt like cheating before, so I didn't say it.

Now that Surrell has offered it, he has acquiesced in his heart.

After pressing the road, the two of them went back to the modification room.

............

At half past five in the morning on September 3, Geely's unmanned car has completed the modification.

The shape of the whole car is still the shape of a vPro SUV, but the core has been completely transformed.

The steering wheel, paddle gears, throttle controllers, etc., were all removed, leaving only a bare center console, under which are dense sensor data cables and several ultra-high-definition cameras.

On the outside, there are 6 sets of Tianyi light detection sensors installed on the front and rear, sides, and roof, and the elongated protective shield looks like a bazooka, which is both funny and bloated.

But it doesn't matter, it's beautiful or not, that's the designer's business, the engineer is only responsible for letting the car move freely through the crowd, then, they succeeded.

............

At 8 o'clock in the morning, the news that the driverless car jointly built by Geely and Tianyi will be comprehensively tested in the downtown area of Zhonghai was overwhelming on the Internet.

At the same time, Geely Chairman Lin Shufu also rushed to Zhonghai and said that he would personally test ride the driverless car.

One stone stirs up a thousand waves;

The eyes of the whole country and even the world have focused on China Shipping......
