After failing the exam, I opened a university

Binjiang Tianbang University, Nanyuan parking lot.

A brand new yellow-painted excavator is “shining” under makeshift spotlights

In front of this excavator, Chang Hao, who was operating two laptops at the same time.

After completing final testing at the software system level.

Chang Hao began to direct several school staff members temporarily called by Su Yan to help him install various sensing equipment and mechanical control equipment for the excavator.

This work lasted a full hour.

After a simple test, all positions of the entire excavator have been covered by sensing devices of different sizes.

Some small cables are wrapped around the body of the excavator, and from a distance, it looks like many small vines have grown on the body of the excavator.

When all of this work is over.

Chang Hao began to operate on a laptop.

Now what he needs to do is to use this laptop as an information output, with the help of GPS equipment attached to the computer, to provide navigation information for the excavator at the receiving end.

After completing this step of the procedure.

Excavators have eyes.

But eyes alone are not enough.

You have to have brains.

The most critical and difficult part of driverless technology is not actually to allow a car to drive according to navigation.

Although a set of technologies that have reached this step can already be called driverless 50 technology.

But this technology cannot really be used in real traffic.

Getting a car to drive from one location to another is simple.

How many meters to go straight, at which intersection to turn, where to get on the highway, how many ETC passages, these things, these things, it is very simple to achieve.

The difficulty is how to deal with temporary road conditions.

Since they are already unmanned, it is necessary to ensure that the safety of unmanned driving is greater than that of manned driving!

If even this point is not achieved, then the so-called unmanned driving is just a piece of paper.

Even if the government decides that such a system can be used on the road, the majority of people who dare to buy such a car will not be the majority.

No one wants to give their life to an unreliable and immature system.

The core key technical difficulty of driverless technology is safety.

Chang Hao’s system, from the beginning of the idea to the current production of finished products, is around the word “safety”.

How to use key technologies such as information technology, AI technology, and self-technology to make the car drive on the actual road the safest is the core part of Chang Hao’s research.

How can driving under an unmanned system be safer than a vehicle controlled by a driver?

At this time, Chang Hao, who was typing on the keyboard on the computer, was being asked the same question by Su Yan.

“Chang Hao, you said that your system was actually built for the goal, and you also said that your system will theoretically be safer than manned driving, how is this?”

For such a question, a question related to the professional field he studied during this time, Chang Hao did not hesitate much and blurted out the answer.

“Unmanned driving can indeed be safer than having a driver, such technology, now actually already available, of course, their technology, or the most advanced driverless technology in the world, they can do it, but the safety of unmanned driving is higher than the safety of ordinary drivers driving vehicles.”

“And my system, I think is safer than the most advanced driverless system in the world.”

“As for Principal Su, you asked me how driverless driving is safer than manned driving, to explain this, in fact, one or two sentences are not clear.”

“But I can give you a few simple examples to give you a picture of the handling of unexpected situations in the state of people and people, and you may understand it by listening to it.”

Su Yan nodded: “You say.” ”

While typing on the keyboard, Chang Hao slowly spoke: “First of all, to give an example of a driver driving a vehicle under sudden road conditions. ”

“Let’s say a car with a driver is driving normally on the highway and suddenly a dog comes out from the right.”

“Such an unexpected situation is unexpected for the driver, and in response to such an unexpected situation, the novice driver (BFDD) often chooses to step on the car while hitting the steering wheel in the opposite direction, hoping to avoid the dog that suddenly drilled out.”

“There are two consequences of this.”

“One is a case of luck, the novice driver may have successfully avoided the dog, and the car did not have any problems, but changed lanes and continued to drive.”

“The other is a case of bad luck.”

“Novice drivers subconsciously hit the steering wheel while pressing the brakes, affected by the speed and road conditions, the friction between the tires and the ground instantly becomes smaller, in this case, the driver’s operation will cause the vehicle to suddenly turn out of control, not only hit the dog, the car also directly hit the guardrail.”

“Or, the novice driver subconsciously hit the steering wheel, the vehicle did not lose control, did not knock the dog away, but when changing to another lane, it was rear-ended by the car from behind.”

“Or something like that.”

“All of the practices I have mentioned above are obviously not safe and not optimal.”

Chang Hao paused, temporarily stopped the work in his hand, and looked at Su Yan seriously.

“If we change drivers from novices to veterans who have been driving for decades, things would be different.”

“As an experienced driver, when faced with the same unexpected situation, his experience will tell him that if you hit the steering wheel while applying the brakes at a speed of 100 yards per hour, there is a high probability that the center of gravity of the vehicle will shift and the body will lose control.”

“So, in the same situation, an experienced driver will definitely not do the same operation as a novice driver.”

“For them, the most correct and reasonable operation is to use the greatest force to control the steering wheel without shifting at the same time, if it is a car with an ABS system, they will directly slam on the brakes, and the car without the ABS system, through their own experience, to point the brakes to achieve an effect similar to the ABS system.”

“What they do is what they think is the best way to deal with the situation at the moment, which is called giving way.”

“The benefits of this are obvious compared to what I just said about novice drivers.”

When Su Yan heard this, he said loudly: “There will be no loss of control of the vehicle, so it will not hit the guardrail or other vehicles, there is no change of direction, so there is no operation to change lanes, and it will not hit other vehicles that are driving in the next lane…”

“The only loss may be the dog’s life, and in the case of deceleration and sudden braking, if the vehicle hits a dog, the damage will not be great.”

Chang Hao nodded: “Just like you said, experienced drivers can do this, in fact, in the eyes of ordinary people, this is already the optimal solution.” ”

“However, I will say that my driverless system can do better than this!”
