Cities: from Heavy Locomotives to Industrial Overlords

Simulation testing is to create various dangerous scenarios in the virtual world to test the response of the self-driving car.

There are many companies that have this kind of scene database, or scene set.Engineers fine-tune details in a scene to see how the car responds to different variables.For example, simulate a mother pushing a stroller across the road, or simulate a long yellow light.

For example, Waymo, a subsidiary of Google, has a Carcraft simulation test software.

In Carcraft, common driving behaviors in real life, such as a car driving in a roundabout, is added by another two cars. Such scenarios can generate thousands of simulation scenarios to test the performance of driverless cars. ability limit.

As a virtual world, Carcraft has played a huge role in reshaping the real world.

There are currently 2.5 virtual self-driving cars in full-modeled versions of Austin, Mountain View, and Phoenix for road simulation tests, including some track test scenarios. Waymo has driven 25 billion virtual miles.

Simulation testing is part of Waymo's self-driving car development. Simulation closely integrates the testing of Waymo's self-driving prototypes on real roads with a "structured test" project at a secret base called Castle in the Central Valley. together.

Su Qin nodded and said, "No way, when we acquired Changjiang Automobile, Changjiang Automobile did not have simulation test software!"

"This can only be developed by ourselves. The time is urgent, so let's check other functions first!"

If there is simulation software, then in the virtual space, the constraints of the real world can be lifted, and thousands of deformations of any single scene can be created, and then the simulation test of the unmanned vehicle can be carried out through these scenes.With the continuous improvement of the autonomous driving software, the performance of the physical test vehicle will gradually improve, and the closed loop of the entire test will start again.

Unfortunately, no, it can only be done step by step.

Now the 177's Leap car is still very weak.

Of course, under normal circumstances, in addition to the simulation test, it is necessary to test the actual test and the real road test.

After passing the simulation test, you can take the self-driving car to a quiet environment for testing.Make sure that the new code will not affect other performance, whether going straight, turning, or reversing.

At the same time, some special scenes can be artificially arranged to test the response of the self-driving car.

After passing the test track, you can drive the car into the downtown area.

However, the automatic driving function cannot be turned on directly.

It is necessary to first ensure stable performance on safe road sections, and then test the full automatic driving.

If you follow the test process, it is very complicated, and there is no way to complete it in a short time.

In such a case, the road test and the test of autonomous driving can only be stopped.

L5 level autonomous driving technology, which is already powerful enough.

Su Qin: "Mr. Guan, I won't go to the test of Feiyue Auto. Please hurry up and do the relevant tests. I still have things to deal with!"

"If there is a problem with the test, immediately take the time to adjust, reinstall or repair."

The key technologies of Feiyue Group's first car are graphene batteries and L5-level autonomous driving.

Because the Donghai International Auto Show is approaching, there is no way to fully test it.

There is no way to experience and test L5 level autonomous driving.

This is rather unfortunate.

But it doesn't matter!

Great opportunities in the future.

Su Qin knows that testing autonomous driving is very complicated.

After three tests of simulation test, road test and real road test, the level of self-driving cars is at least not much different from that of humans.

But self-driving cars also have a killer feature: emergency braking systems.

With powerful sensors, self-driving cars can effectively predict crashes and then brake hard in safe areas.Unlike humans, they often panic in emergency situations, resulting in car accidents.

Su Qin asked Guan Lin to handle the test work of Feiyue Auto.

The test period for the car is about five days.

Time is tight!

But no way!

There are about ten days left to check the gaps.

This is critical.

As long as Feiyue Auto can be mass-produced, it must become a blockbuster ace product of Feiyue Group.

In the next few days, Su Qin also had time to go to Feiyue Car to check the test situation.

Because there is no road test, there is not much to watch in the related tests, and they are all normal model tests and so on.

As for the model, serial number, price positioning, etc. of this Feiyue car, Su Qin already has his own ideas, and it has not been announced yet.

Feiyue Automobile is very amazing, it can be said that it completely broke everyone's perception of cars.

In other words, Feiyue Car is a mass-produced concept car!

There are two types of concept cars.

One is a real car that can run, and the other is a design concept model.

The first type is relatively close to mass production, and its advanced technology has entered the test and is gradually becoming practical. Generally, it can become a new product put into production by the company in about 5 years.
