What is the patented technology of autonomous driving?

101October 2 1 day, Musk announced a heavy news on Twitter. Tesla's fully automatic driving test version was officially updated. The beta will be tested by pushing a small number of beta versions first, and then the beta will be gradually opened. Musk said that in the latest version of the system, Tesla's self-driving FSD software has been revolutionized, making it possible to complete 90% interference-free driving.

According to Musk's description, in the latest test version, Tesla vehicles equipped with FSD autopilot can navigate in and out of the highway without any driver intervention, and also allow drivers to summon vehicles in private parking lots and navigate to designated locations; It can also recognize stop signs and traffic lights and act accordingly: it can even fully realize automatic driving on city streets.

This time, the arrogant Musk used it for the first time: We will be very cautious, and so should he. This sentence, you know, this tone completely violates Musk's brave and adventurous character. It is understood that the first batch of FSD beta will be first pushed to "only a few professional and cautious drivers." But up to now, many media and individual car owners have received the update tips of the beta version.

In fact, as early as August this year, Musk publicly promised that the update of FSD would be a qualitative leap, because it was a basic architecture rewrite, not a gradual code adjustment. The reprogrammed new system can extend Tesla's autonomous driving ability from 2D to 4D, which not only means that the vehicle can not only perceive the surrounding three-dimensional world, but also predict other environmental factors such as position, direction and speed, and make its own judgment.

Although so far, the official has not announced the FSD? The specific content of the beta version, but as can be seen from the multimedia road test video, the new version of FSD autopilot has designed a brand-new UI model, which allows the UI of the vehicle to handle different light and shadow of the car body in different lighting environments during the day and night. The left Chebang area, which originally occupied one third, has been pushed to nearly half of the proportion, and the proportion of car models has also been raised from the lower part to the center. Vehicle control can be done directly by clicking on the body, such as the tailgate and the front cabin.

As can be seen from the official video, 90% beta users use FSD automatic driving on the route from home to restaurant, including automatic processing of the route around the island, active avoidance of through trains, rapid lane change of urban roads, 90-degree turn at intersections, driving on unmarked roads and identifying vehicles on both sides, ice cream cones to identify the difficulty of hell, and adding automatic parking. He can even recognize a grass by the roadside. .....

After several days of road test, Musk announced the new version of FSD. The beta version will be updated every five days, and by the way, I also spit out the simulation tests in recent days, indicating that if I don't do the tests, I will definitely overestimate my achievements. Therefore, for the sake of safety, the owner had better put his hand on the steering wheel, supervise the road conditions and be ready to take over the vehicle at any time.

The most difficult thing for Tesla to imitate is the powerful learning ability of FSD chip. According to a patent of Tesla, fully automatic driving technology is a machine learning and training technology for generating highly accurate machine learning results. He can create a database by capturing data from sensors on vehicles and by capturing lane lines, lanes, traffic conditions, obstacles, traffic signs and so on. Combined with the vehicle driving data captured by odometers and other similar sensors, the captured data set is transmitted to the training server to create a training data set for training the machine familiarity model.

Through the test, it is found that when the machine is familiar with the road section, it will gradually improve its driving ability through learning. This progress makes the driving of the machine turn to think like a human being, and the driving style is more anthropomorphic. From this point of view, Tesla's FSD autopilot is still at the leading level in the industry, but one thing he can't understand about such a powerful system is reversing into the warehouse. Even if Tesla is equipped with FSD, the performance of automatic parking has been unsatisfactory, and it can even be used in the industry.

As of now, Tesla said that they originally expected to produce and deliver 500,000 electric vehicles in 2020. At present, the factory in fremont, California has increased the production capacity of Model3 and Y to 500,000 vehicles per year, and it is expected to reach full production by the end of 2020 or at the beginning of 2002/kloc-0: the production capacity of the Shanghai factory in China has increased to 250,000 vehicles, and it is currently running in three shifts; The factory in Berlin, Germany is under construction, and the equipment should be in place in the next few weeks, and it is expected to be put into production next year.
