When talking about unmanned driving, the first thing to do is to be clear about what is truly "unmanned driving"?

People often confuse the three words "unmanned driving", "autonomous driving" and "driving assistance".

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

Driver assist technology is currently deployed on mass-produced vehicles, commonly known as advanced driving assistance systems (adas).

There are currently as many as 20 types of this technology, including automatic navigation system, Internet of vehicles, adaptive cruise, lane offset alarm system, lane keeping system, forward vehicle collision warning system, night vision system, adaptive lighting control, pedestrian protection system, etc., which can all be called driving assistance technology.

Primary Adas mainly use passive alarms. When a vehicle detects potential danger, an alarm will be issued to remind the driver to pay attention to abnormal vehicle or road conditions.

The latest ADAS technology has become more common.

The best-in-class industry is currently doing is Israeli mobileye, whose adas products account for 75% of the global market share.

What is a little awesome than driving assistance is called "autonomous driving".

Compared with driving assistance, autonomous driving requires stricter technical and vehicle performance.

The most core of them is the "error omission rate" in the "target recognition algorithm".

"False omission rate" is also the most important indicator that distinguishes driving assistance and autonomous driving.

For example, there is an AEB in autonomous driving (autonomous emergency braking). If the brakes are constantly incorrect, it will pose a threat to the safety of the vehicle; the rate of underreport is also equally important. Because if there is a misreport, the car may be destroyed and the person will die.

Tesla had a car accident in 2017, and the autonomous vehicle crashed into a horizontal trailer, which was a missed report.

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

Without high-precision maps, it is very common to guide you into the gutter (funny face).

In addition, the integration of vision and radar is also an important option for forming autonomous driving. It has been explained in the previous article, so I won’t talk about it here.

Finally, there is driverless driving.

Unmanned driving = complete autonomous driving, that is to say, in unmanned driving mode, driving is completely left to the AI ​​system.

There is no steering wheel or accelerator in the driverless vehicle, and there is only one start/close button. After getting on the car, click the "Start" button to tell the system the destination, and the car will carry you to the destination you want to go.

As for the driving process in the middle, how to walk and how fast you drive, the system has the final say. You just need to sleep in the car or have sex with your girlfriend.

Google’s driverless cars are truly driverless cars.

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

The driverless car that Li Yanhong drove is strictly a car with advanced autonomous driving functions.

Why is whiteness not good?

Because Baidu has not developed a complete AI system, and the integration of vision and radar is not done properly.

Speaking of this, we have to mention that there is a more awesome existence in unmanned driving, called "people-oriented human-machine coordinated driving"; it is referred to as "man-car integration".

Have you ever played violent motorcycles?

Someone is going to criticize you later, so you can beat him half to death after you throw a stick.

The AI ​​technology that integrates man and car is so smart.

For example, when you encounter a naughty child, an older bad guy paddles a car, the vehicle automatically warns you, and you don’t listen to the warning, and you will automatically drive away from the parking space. Before leaving, you will even "sneer" on your face.

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

"Hello, Mr. Han, I have long admired Daming..." The chief engineer took the initiative to step forward and stretched out his hand without any airs.

Han Yi also smiled and grabbed the other party's hand and said, "The potter is so polite..."

After a few greetings, Han Yixu held the other person's arm and walked towards the temporary lounge in the exhibition hall.

The six girls standing next to Guangkejianren's display cabinet were looking at their young boss while introducing products to customers.

An 8-point beauty, while elbowing her elbow, then covered her mouth with her hands and whispered: "Hey, our boss is so handsome."

The girl was whispering, with long and beautiful legs under her skirt. At this time, her beautiful eyes were slanted, and her eyes were asked with a deep meaning: "Are you drooling?"

The 8-point beauty was stunned for a moment, and soon realized that she was as red as cooked shrimps. She looked around and saw that no one noticed them, and used her hands to squeak her, "You big lustful girl..."

In the lounge here, Geely's chief engineer was straight to the point, "I believe that Mr. Yao has already told you about the situation, right?

We are very sincere in Geely. If Mr. Han is willing, we will do our best to cooperate with you."

Han Yi has decided on things, and he doesn’t have a mother-in-law and mother. Now time doesn’t wait for anyone, so all manufacturers must be able to see the power of Tianyi’s unmanned driving during the expo.

Going back, using the method of bundled sales, forced those auto manufacturers to purchase their light detection sensors, two-in-one!

"There is no problem with cooperation, but I hope you will start preparing now. The comprehensive site test will begin at noon tomorrow. The tentative targets are Lujiazui CBD Commercial Area and the Inner Ring Elevated Road."

"Ah... in Lu Jia's mouth?" Geely Chief Engineer, including two assistants, was surprised, "Mr. Han, is this... going to be too aggressive?"

Han Yi smiled and said, "Don't worry about these. Since I said it, I must be sure."

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

…………

At 4:30 pm, 11 engineers came to Geely headquarters and also brought a car for unmanned modification, the 2019 vori-suv.

Not as reluctant as Tao Yang agreed, Geely's senior executives heard that Tianyi wanted to use their cars for a comprehensive self-driving test, so they almost jumped up.

Let’s not talk about whether Tianyi can completely achieve unmanned driving like Google. What if it can’t be done?

At that time, the global attention will be focused on Geely. Their cars will definitely be sold with hot sales, stocks will rise sharply, and there will be countless benefits.

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

Dozens of engineers from Geely Jia Tianyi here unloaded the Borui Suv in the room provided by the International Exhibition Hall to carry out modification projects.

This is a complex project involving countless sensors and systems fusion;

Tianyi Chief Engineer Su Ruier, Feng Da and Feng Er all participated.

They mainly optimized the algorithm recognition and moved the system and big data computing that Tianyi had not had time to seal and test onto this boruis suv.

Algorithm recognition is the basis of unmanned driving. If the surrounding environment cannot be correctly perceived, then the subsequent cognition, decision-making and control will be all over the air.

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

Han Yi called Suriel out.

The two walked from the east gate to the road.

The roads are full of traffic at night, and the headlights meet with the street lights to form a sea of ​​light.

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

Surel "thinked" for a while before saying: "It's not a big problem, but if you want to achieve a stunning level, you still have not integrated all aspects such as algorithm recognition, systems, and adas."

"What do you think you should do?"

Suriel said directly: "Insert the back door in the system, if an accident occurs, I can take over the vehicle directly to ensure that it is foolproof."

Suriel's proposal was something Han Yi had long thought of.

Such things are only allowed to succeed, not fail.

The driverless driver itself is now at the forefront. Not to mention a car crash, if there is a little friction, it will be flooded by saliva. The indirect influence is Tianyi's reputation.

I just felt a bit cheating before, so I didn't say it.

Now Surel has taken the initiative to propose, and he has agreed in his heart.

After pressing the road for a while, the two of them returned to the modification room.

…………

At 5:30 am on September 3, Geely Unmanned Car has been modified.

The entire car has a shape of a vora SUV, but the core has been completely renovated.

The steering wheel, paddle gear, throttle controller, etc. were all removed, leaving only a bare center console, underneath the center console were dense sensor data cables and several ultra-high-definition cameras.

On the outside, front, back, and on both sides, the roofs are equipped with 6 sets of Tianyi light detection sensors; the extended protective cover looks like a bazooka, both funny and bloated.

But it doesn't matter. Whether it's beautiful or not is the designer's business. The engineer is only responsible for allowing the car to freely shuttle through the crowds, so they will succeed.

…………

At 8 a.m., the news that the driverless car created by Geely and Tianyi will be conducted in the downtown area of ​​Zhonghai will be overwhelmed online.

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

One stone stirs up a thousand layers of waves;
Chapter completed!
