"The main reason why we intervene manually is that the roads planned by the two vehicles overlap. If they are allowed to drive along the same route, it would be meaningless, so we think that we should intervene in one of the vehicles and let it choose Take another route that is not optimal.

In fact, no matter it is based on the map and terrain data information obtained from previous reconnaissance and mapping, or the latest satellite map, there is no way to accurately grasp the actual topography and landform information of the area. In some areas with frequent geological conditions, the topography will change every minute, causing roads to be interrupted and travelers to be blocked.

Therefore, although our on-board automatic driving system for medium-sized unmanned intelligent combat vehicles selects a route planned based on satellite maps and known map and landform information, it does not mean that it will strictly follow this route during the entire situation. .

The medium-sized unmanned intelligent combat vehicle will basically drive along this planned route, but it will also make corresponding changes based on the relevant situations encountered during the driving process. For example, if there are large obstacles in front that cannot be passed, Then the on-board automatic driving system of the medium-sized unmanned intelligent combat vehicle will plan a route to avoid this obstacle, and then return to the original route.

If this line is completely interrupted, the medium-sized unmanned intelligent combat vehicle will not return to the original route. It will re-plan the best route to the destination based on its real-time location, and then change the direction of travel and continue driving. until you reach your 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 Trends in medium-sized unmanned intelligent combat vehicles.

Of course, there is another extreme situation, that is, all routes leading to the destination are blocked. At this time, the vehicle will not directly return 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 no new instructions are issued within a certain period of time, the medium-sized unmanned intelligent combat vehicle will autonomously return along the original road at this time. In other words, it will return to the preset rear assembly point, or position and return based on 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 finished speaking, someone started asking.

"Haha, 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, or not applicable, it depends on the user's choice. choose.

There is a very popular saying among car companies nowadays: You can use it, but you can’t live without it. Zhou Yonghui replied with a smile.

After hearing Zhou Yonghui's words, this person did not continue to ask questions, and other people at the scene nodded in approval.

While they were talking, the vehicle had already traveled several hundred meters away. Two medium-sized unmanned intelligent combat vehicles were driving through the desert, dragging two tails of smoke and dust.

"The vehicle was traveling very fast and was not traveling on an off-road road at all."

"Yeah, and it's very stable. There are no big bumps in the vehicle, and there are no starts, stops, or frequent acceleration or deceleration."

"Even if an experienced driver comes to drive in this kind of road conditions, he may not do better than it."

…

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

At the same time, two temporary large screens set up by technicians also displayed the first-person view of the two vehicles while they were driving and the surrounding images of the car body.

Through the first-person driving scene, everyone can clearly see the route ahead that has been planned in the scene. This is the outline of the road ahead drawn with a green dotted line. Depending on the shape of the vehicle, this green road outline also changes in real time, and sometimes yellow-red lines are displayed.

Zhou Yonghui, our on-site tour guide and commentator, also introduced it at the right time: “Please take a look, in the first-person driving footage of two medium-sized unmanned intelligent chariots, a green road outline appears. This is the vehicle-mounted intelligence. The driving route planned by the driverless system. So you can see that this route is constantly changing while the vehicle is driving.

As we all know, in traffic signs, green represents passage, and the green road outline represents that this section of road can be passed smoothly. The yellow route outline represents slow travel and the speed should not be too fast. The red road outline usually means that the road is impassable or encounters obstacles, etc.

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.

Hearing this question, Zhou Yonghui answered with a smile: "We have equipped this vehicle with our latest millimeter wave radar, new generation lidar, and our most advanced compound eye system, thus forming a powerful environment perception system.

With this system, we can see clearly four to five hundred meters away and perceive environmental changes one to two hundred meters away without obstacles. In this way, more reaction and processing 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 pointed at the green road outline on the big screen and introduced with a smile: "Please see, our medium-sized unmanned intelligent combat vehicle has relied on its powerful environmental perception capabilities to extract perceptions and plan ahead. The traveling route is about more than two hundred meters, which also means that it can maintain a fast traveling speed even in such a complex terrain environment.

Unlike some other systems and vehicles, in this road situation, due to the decline in perception and data processing capabilities, the vehicle intelligently drives slowly, like a turtle walking or roaming on the moon. "

Speaking of this, Zhou Yonghui still had some unfinished thoughts and said: "Let me tell you another piece of news. The on-board intelligent unmanned driving system on our car is actually the intelligent lunar surface of our 'Wangshu'. The intelligent travel system of the patrol rover is improved based on the above, and it can be said that it is very powerful, because this system has been fully verified in the harsh lunar environment."
