Chapter 171 First Experience of Unmanned Driving

In fact, there are some differences between software simulation and reality, for example, the visual range of the camera is different.

In reality, it should be able to shoot in all directions, but this effect cannot be achieved in simulation.

Probably only a small part of the data can be simulated, and the radar simulation is relatively realistic, which can tell the owner where there are objects and how big they are.

But this also has some advantages. If they can make very powerful algorithms with less data, they should perform better in reality.

But the ideal is beautiful, but the reality is cruel.

The algorithm they made in the simulated software can basically achieve zero accidents, but in the real test...

They used some modified electric vehicles for their real-world tests.

At the beginning, they also collected some data instead of starting the test directly, so they gave their electric vehicles to the takeaway staff for free.

After all, they ride electric bicycles back and forth in the streets and alleys every day.

It can collect more data than providing it to other people, such as ordinary office workers.

Even after Cheng Wen realized the limitations of the simulation platform, he adjusted his simulation platform according to the data they provided.

But because the data is too small, not much can be changed.

To this end, Cheng Wen increased investment and transformed more than 200 electric vehicles in total.

Use them together to collect data.

It is even free for people other than the delivery staff, but there is a requirement that they must ride the car for 8 hours a day.

There is no limit to the location, they can choose freely.

But time must be enough, Cheng Wen is just to collect data.

After a version of their algorithm has been improved, the real real-world testing begins.

All the engineers came out of the office for the first time in order to get a feel for their own algorithms.

Personally ride their electric car installed with their own designed intelligent driverless algorithm.

But they can also take over the entire vehicle at any time.

After all, their algorithm has not been field-tested, and no one knows if there will be any problems.

Therefore, it is necessary to be able to be controlled by people in the early stage.

Just like the Baidu unmanned taxis that appear in Changsha now, some journalists and friends go up and take a taxi.

This is an unmanned vehicle, and it is free now.

But after entering, you will find that there is a safety officer in its driving position.

Some people who don’t understand say that self-driving cars also require one or two safety officers in front of each vehicle.

What kind of unmanned vehicle is this, even more waste of manpower than ordinary human vehicles.

They didn't know that this batch of cars was still being tested and hadn't really been put into use.

So in the early stage, someone was watching, and if a problem is found, manual intervention can be performed immediately.

This is to ensure the safety of passengers and passers-by. It is a responsible approach of the enterprise.

This is something that will definitely be experienced in the early stage of driverless driving.

If the unmanned driving technology matures in the later stage, the role of safety officer is completely unnecessary, and this role should be forgotten by people.

Even today's unmanned vehicles can be operated by people through mechanical devices, and can be unmanned through software.

After the unmanned technology matures in the future, there will definitely be vehicles without steering wheels, clutches and brakes.

At that time, all the driving of the vehicle will be controlled by software, and people can completely escape from the heavy driving tasks.

Cheng Wen also read an article before that introduced driverless technology. One person said that now he still needs to send his children to school every day.

You can also communicate with your child on the road. If there is no driver, then he will have no time to communicate with the child.

Cheng Wen felt that this person's thinking was too rigid.

Can't we send our kids to school with driverless cars?
It is completely possible for two people to ride together, and because there is less distraction from driving, you can put all your energy on communicating with your children.

Many people liked Cheng Wen's message at the time.

Manned driving in the early stage of unmanned driving is necessary.

It didn't take Cheng Wen for them to usher in the first experience of manned unmanned driving.

This time it was all young boys who came to the test.

Most people ride electric bikes.

Downstairs in the company, Cheng Wen and the others started riding electric bikes, but they were completely manually controlled.

Because the flow of people here is still very large.

They need to ride to an area with less traffic.

Originally, they could also use a truck to pull all the electric vehicles there, but let everyone familiarize themselves with this electric vehicle in advance.

So that plan was abandoned.

More than a dozen people set off in unison, and walked towards a place with little traffic.

They rode there in less than 20 minutes.

There are very few people in that area, and there are not many cars.

At this point, a dozen people separated.

Cheng Wen turned on the autopilot, and kept his hands on the handles, but he didn't use any force.

At the beginning, Cheng Wen didn't feel safe at all, he just felt that his fate was entrusted to others.

Cheng Wen was very afraid that there might be some major bug in the software they developed, but fortunately, they adjusted the speed of the vehicle, and the fastest speed was no more than 10 kilometers per hour.

Some running speeds can be faster than this speed, and this stable speed gives Cheng Wen a sense of security.

He never thought that he would let such a slow speed bring him a sense of security.

After a while, they gradually became familiar with it, and found that the modified vehicle still had balance, even if it stopped there, it would not fall to one side.

This also gave Cheng Wen a lot of security.

But after a while, he gradually became familiar with it, and he also met a few people who could dodge perfectly by autopilot, or make way for them.

It can also stop by itself before traffic lights, or pass through.

Gradually, Cheng Wen became less nervous. Sometimes he met employees of his company who were also testing on the road, and would say hello to them.

Cheng Wen saw that they also relaxed a little from the original nervousness.

However, it is not completely relaxed, and it also maintains vigilance ready to take over the vehicle at any time.

After running at a speed of 10 kilometers for most of the day, an embarrassing thing happened. Their tram ran out of electricity.

Originally, they could continue the test, but had no choice but to call a truck to pull these vehicles back and charge them.

The test results on the first day were good, and there were no problems or accidents.

This is mainly due to the fact that the data they use is both video and radar. If one cannot be used, the system will pull over and wait for personnel to repair it.

Because there was an accident with another vehicle before, when using unmanned driving, it regarded a reflective object as if it did not exist, and hit it with its head.

In the end it ended up in a car crash.

But this power made Cheng Wen have to think about the pace of their testing.
