Vol 3 Chapter 2166: The old driver is not necessarily better than it is

"The reason why we intervene manually is mainly because the roads planned by the two vehicles overlap, and if we let them drive along the same route, it is meaningless, so we think that we intervene in one of the vehicles and let it choose Take another route that is not optimal.

In fact, whether it is based on the map topographic data information obtained by previous reconnaissance surveying and mapping, or the latest satellite map, there is no way to accurately grasp the actual topographic and topographic information of the area. In some areas with multiple geological conditions, the topography and landforms will change every minute and every second, causing road interruptions and obstruction of peers.

Therefore, our medium-sized unmanned intelligent chariot vehicle-mounted automatic driving system, although the route selection is planned based on satellite maps and known map landform information, it does not mean that the whole situation will strictly follow this route. .

The medium-sized unmanned intelligent chariot will basically drive along this planned route, but it will also make corresponding changes according to the relevant situations encountered during the driving process, such as there are large obstacles ahead that cannot pass through, Then the on-board automatic driving system of the medium-sized unmanned intelligent combat vehicle will plan a route to bypass the obstacle, and then return to the original route.

If this line is completely interrupted, the medium-sized unmanned intelligent chariot will not return to the same path. It will re-plan the best route to the destination according to its real-time location, and then change the direction of travel to continue driving. until reaching the destination.

At the same time, the medium-sized unmanned intelligent combat vehicle will also feed back the relevant situations encountered and the real-time estimated time of arrival at the destination to the rear command and control center or its commander, so that the commander can better understand The trend of medium-sized unmanned intelligent combat vehicles.

Of course, there is another extreme situation, that is, all routes to the destination are blocked. At this time, the vehicle will not return directly and autonomously, but will transmit relevant information to the rear command and control center or the on-site commander, waiting for new instructions to be issued.

If there is no new order issued within a certain period of time, the medium-sized unmanned intelligent combat vehicle will return along the original road autonomously at this time. In other words, it will return to the preset rear staging point, or locate and return according to the position of the control terminal or the rear command and control center. "

"But in this case, wouldn't it be easy for the enemy to use it to find our commander or the rear command and control center." As soon as Zhou Yonghui's words fell, someone asked.

"Hehe, what you said is indeed a problem. However, it depends on the user's choice. We are only equipped with this function. As for whether to turn it off, disable it, or not, it depends on the user's choice. choose.

There is a very popular saying in the car companies that you can use it, but you can't do it without it. " Zhou Yonghui replied with a smile.

Hearing Zhou Yonghui's words, this person did not continue to ask questions, and the other people at the scene also nodded their approval when they heard the words.

When they were talking, the vehicle had already traveled about a few hundred meters. Two medium-sized unmanned combat vehicles dragged two tails of smoke and dust in the desert next door.

"The vehicle travels very fast and does not act on the off-road section at all."

"Well, and it's very stable, the vehicle doesn't have too much bumps, and it doesn't start and stop, and frequent acceleration and deceleration occur."

"Even if an old driver comes to drive in this kind of road conditions, it's not necessarily better than it."

……

Looking at the driving performance of the medium-sized unmanned intelligent chariot, now everyone is starting to talk about it.

At the same time, the two temporary large screens erected by the technicians also displayed the first-view pictures and the surrounding pictures of the two vehicles during the driving process.

And through the driving picture from the first perspective, everyone can clearly see that the route ahead has been planned in the picture. This is the outline of the road ahead drawn by the green dotted line, and according to the form of the vehicle, this green road outline is also changing in real time, and sometimes yellow-red lines are displayed.

Zhou Yonghui, the on-site tour guide and commentator who organized me, also introduced at the right time: "Everyone, please see, in the first-view driving picture of the two medium-sized unmanned intelligent chariots, a green road outline appears, which is the intelligent vehicle on the vehicle. The driving route planned by the driverless system. So you can see that this route is constantly changing during the driving process of the vehicle.

Everyone knows that in traffic signs, green represents traffic, and the green outline of the road represents that the road can be passed smoothly. The yellow outline of the route represents slow travel, and the speed should not be too fast. The red outline of the road usually means that the road is impassable, or encounters obstacles and so on.

It is marked with three colors, so that the rear command and controller can better understand the movement of the medium-sized unmanned intelligent combat vehicle. "

"How far can this car see?" an expert at the scene asked aloud.

Hearing this question~www.readwn.com~ Zhou Yonghui replied with a smile: "We have equipped this car with our latest millimeter-wave radar, a new generation of lidar, and our most advanced compound eye system, which constitute its powerful environment perception system.

With this set of systems, we can see clearly from a distance of four or five hundred meters and perceive changes in the surrounding environment at a distance of one or two hundred meters without obstacles. In this way, more response time can be reserved for the on-board automatic driving system or on-board intelligent control system of the medium-sized unmanned intelligent combat vehicle, so as to calmly handle various crisis situations. "

Zhou Yonghui said, pointing to the green road outline on the big screen and introducing to the crowd with a smile: "Please see, our medium-sized unmanned intelligent chariot has been able to extract perception and plan ahead with its strong environmental perception ability. The travel route of about 200 meters also means that it can maintain a relatively fast travel speed even in such a complex terrain environment.

Unlike some other systems and vehicles, in this road situation, because of the decline in perception ability and data processing ability, it drives intelligently slowly, like a turtle walking, or a moon roaming. "

Speaking of this, Zhou Yonghui still had some unfulfilled thoughts and said: "Let me reveal to everyone that the on-board intelligent unmanned driving system on our car is actually our intelligent lunar surface on our 'Wangshu' spacecraft. The improvement on the basis of the intelligent travel system of the patrol rover can be said to be very powerful, because this system has been fully verified in the harsh lunar environment."
