Camera, millimeter wave radar, laser radar, ultrasonic sensor, V2X network link technology ... The vehicles of major participating teams are almost "full armed armed".
On September 12th, the 2020 "I-Vista Automatic Driving Cars Challenge" is in the Brain Challenge, 15 participating teams must not only deal with the test of the random scenes of difficult upgrades, but also to cope with the sudden autumn rain.
Compared to the previous competition, the first day of this competition presented "white heat", the most powerful car brain challenge and the virtual simulation challenge took the lead in debut, and the team proposed the most "stringent" test.
The relevant person in charge of the Intelligent Nets in China, the "Strong Car Brain Challenge" simulation is a typical urban transportation scene L4-L5 automatic driving. The game is selected in China's auto research Li Jiayuan District with a bridge, tunnel, cross / Ding junction, hump bridge and other urban roads.
Different equipment and technologies are required for different city markets. However, all scene challenges can be completed without mounting related equipment. How does the vehicle use the ability to obtain information, transform into specific operational behavior, and determine the final strength of the team to participate in the vehicle.
At 9 o'clock in the morning, the Chongqing University of Posts and Telecommunications took the lead in the starting point. As the game progresses, many teams' vehicles have a variety of situations, and even the team has given up some projects. Most teams can successfully complete the challenges of some basic scenes, but facing pedestrians traversed (V2i), tunnel pass, valet parking, etc., but frequent "hanging". From the actual game situation, most teams give up one or several scenes described above.
"There are many scenes of this year, there are many scenes that are randomly, this is more accommodated, and the participating vehicles will not be able to modify the specific procedures according to the specific situation of the scene, which is equivalent to the 'closed tutorial", and perceive the vehicle automatic driving system , Decision-making and control capacity require high. "China Sports Intelligent Network Experts said.
In the tunnel passage scenario in the previous competition, after entering the tunnel, in addition to the GPS signal is lost, this time is also set up in the case of simulating flooding transit tunnel water, there is also interference on the radar.
In addition, the hump bridge scene is also a big difficult gate. The hump bridge scenario requires the entries to pass the bridge surface with the specified speed. When the upper bridge does not have slope or stagnation, the speed of the lower bridge requires a speed at 23km / h. Many participating vehicles appear in the lower bridge, and the speed of the speed is exceeded. Tsinghua Slim 2 team, suddenly turned off when there was a hump bridge, and had to manually intervene.
The valet parking will be one of the automatic driving and take the lead in commercialization. The type of parking space in this competition is the vertical square mapping in the garage. "After entering the garage, the GPS signal is easy to shield loss, and the vehicle needs to automatically recognize the empty parking space, and it is difficult to know." The expert said.
In addition, today's sudden autumn rain, the road is slippery, "sight" is blurred, and also gives a severe test to "car brain". For example, the star is not debugging, temporarily abandoning the game. Many teams also lost their sensitivity, liner, and failed to identify obstacles.
As of the reporter, the competition is still in the hot, at present, far from the team, Jinglong 1 team, Jinglong 2 teams, 2000 points, 1980, the first three, Tsinghua Swallow 2 team, 1 team, Beijing The Dragon 3 team followed by a few tens of points.
