Chapter 2290 Military-grade autonomous driving system unveiled
【Revision】
Finally, due to limited time, Wu Hao chose to demonstrate a military-grade autonomous driving system.
Leading the leaders and everyone to the military-grade autonomous driving system exhibition area, Wu Hao introduced to the leaders the Warrior military vehicle equipped with their autonomous driving system.
"The Warrior military vehicle in front of you has been equipped with our military-grade autonomous driving system. The appearance of the entire military vehicle has not changed much and remains the original model. We mainly equip the relevant sensors on the windshield.
Above the roof beam. Here, you can have a better view and avoid being hit by rocks and trees when off-road.
In addition to this set of sensors, we are equipped with a set of sensors on both sides of the car body and behind the car, so it can sense 360-degree panoramic environmental data information around the vehicle." As he spoke, Wu Hao pointed at the person next to him.
A staff member pointed out that a large screen next to the vehicle displayed the surrounding image data sensed by the vehicle's autonomous driving system sensors.
The first thing is a panoramic image, then the entire color changes to black and white, and then there are countless dense lattice cloud images. Then the entire image is modeled to form a three-dimensional graphic image.
"Through the thousands of laser radars we carry on the car, we can scan and sense the surrounding small objects very accurately and precisely. Even if it is a nail or a leaf, it can accurately sense it.
With a scanning frequency of hundreds of times per second, any high-speed moving object can be accurately detected, even a bullet.
Therefore, with this vehicle-mounted environment perception and detection system, we can equip this autonomous vehicle with an active defense system on this basis. In other words, with its powerful performance, we can intercept some incoming missile rockets
Bombs and other attacks will greatly improve its battlefield survivability."
Speaking of this, Wu Hao paused briefly, and then said again: "We know that the current civilian autonomous driving technology, in addition to the on-board detection and perception system, also relies on accurate maps and satellite navigation data.
In addition, it also has a very rigid condition, that is, it must have a complete road system. In other words, it can only drive on a complete road system. Once it breaks away from this road system, its
The autonomous driving system will fail,
For civilian vehicles, these are not problems, because their main companion scenes are on the road. But for military vehicles, this is obviously not possible. In war, the enemy will not sit back and watch us have complete
The road system provides blood transfusion and support for the battlefield, so roads must be the first focus of the opponent's attack.
At this time, the civilian automatic driving system loses its function, so if we want to equip military vehicles with automatic driving systems, then we must solve this road problem.
In other words, in addition to autonomous driving on paved roads, our autonomous driving system also needs to be able to achieve traffic on dirt roads, even in roadless environments. The key to achieving this goal lies in the vehicle-mounted environment perception and detection system.
superior.
To put it bluntly, we must have bright and sharp eyes to be able to perceive information about the surrounding environment and provide direction guidance for the movement of our vehicles, so as to avoid some roadblocks and find a suitable route for passing.
To this end, we have specially set up a technical research team to conduct research and improve technology on software and hardware technology in this area. In the end, with our efforts, we achieved thousands of technological innovations in this field.
With such a precise vehicle environment perception system.
With the environment perception and detection system, we must also have a matching vehicle-mounted intelligent driving system. To put it bluntly, we must let the vehicle learn how to handle various road conditions. In addition to some of our technical accumulation, this also requires a large amount of data.
for learning and training.
In this regard, we would like to thank the military for its support. With their help, we collected the driving data of military vehicles under the terrain and climate environment of various regions in the country. We refined the data and information, and then conducted analysis, learning and training, so that we can
The vehicle-mounted autonomous driving system gradually learns from the driving experience of outstanding military drivers and their ability to handle complex road conditions. This enables this intelligent driving system to grow step by step and learn and adapt to autonomous driving capabilities in various terrains."
With that said, Wu Hao gestured to the staff, and then introduced to the leaders and everyone: "Next, we will show you a test record video of our autonomous driving system."
During Wu Hao's introduction, the test record video on the big screen also started playing.
"Please take a look, this is a test video of our military-grade autonomous driving system. In the picture, the car will undergo a 300-kilometer autonomous driving new performance test project."
During the entire test process, except for a small section of paved road in front, for safety reasons, we had people sitting in the driving seat, ready to take over the vehicle at any time to avoid unsafe accidents. There were no people in the car on other sections of the road, and the autonomous driving system was fully autonomous.
Control the movement of the vehicle.
During the entire testing process, we do not allow manual intervention. Once manual intervention occurs, it means that the test fails.
We use the remote control system to issue instructions to the vehicle's autonomous driving system and determine its destination.
"Note that this destination is not the exact location information we already know, but a satellite positioning coordinate, that is, latitude and longitude information. The real battlefield is not like the city, which has precise location information. Therefore, the vehicle automatic driving system needs to be based on the purpose
You can use the longitude and latitude information of the place to plan your travel route independently, and then choose an optimal route for driving.
We can see that 30% of the route it planned is paved, 40% is dirt road, and the remaining 30% is off-road travel in a roadless state.
.”
"Under what conditions did it plan and select this route?" an expert present asked. Obviously, he was also very interested in this autonomous driving system.
"Based on the conditions set by our rear command center, and then integrating the data information of the satellite map and the terrain information of the digital map for planning and selection. The system will analyze the terrain and climate information of the area it passes. For example, the terrain is steep and the driving
Dangerous, but the distance is short and the distance is close. The system will weigh it. If the rear command center issues an emergency order and the materials need to be transported to the front line as soon as possible, then in the case of time emergency, the system will weigh the pros and cons and risk driving through. If
Without such an emergency order, the vehicle will choose an optimal route with good road conditions, easier passage, and a relatively short time."
