Does the chance of Autopilot “really†after retrofitting a radar can be greatly reduced? Let Muskke tell you why
On Sunday, Silicon Valley iron man Maskee released a long-awaited new upgrade kit for Tesla Model S and Model X. The upgrade kit was aimed at the previously controversial Autopilot system (resulting in multiple fatal traffic accidents). .
With this upgrade, Tesla's main sensor system will change from a camera to a radar. In fact, Tesla cars produced after 2014 are equipped with radar systems, so they can be seamlessly upgraded without the need for new hardware.
"The most exciting thing is that we have been able to use the radar system very effectively," Musk said in an interview. At first, radar was only an auxiliary sensor for Tesla's camera system, but it had great potential and was a fast-reacting all-around player. "No matter what the obstacles on the road, the radar can always easily detect and issue warnings to prevent collisions. But to change the visual system, you need to know the detailed types of obstacles." Â
When asked if the new system can save the driver using the Autopilot system under the same circumstances (for the previous fatal car accident), Musk stated that he did not dare to pack the ticket, but he and the technical team believe that the new system must be accurate. To find the large trailer that blends in with the sky, the radar system can not be disturbed by the strange light.
However, when Musk introduced the new upgrade, he also stressed that Autopilot could not solve all potential problems. "I specifically mentioned this to tell you that you are not 100% safe," said Musk, who hopes that the new upgrade will reduce the accident rate by half.
“Perfect security is an unachievable goal. We can only constantly upgrade the probability of security. In the future, tens of millions of self-driving cars will be on the road. Even if its error rate is one in a billion, we may also face The tragedy of the car was destroyed."
In addition, the possession of Tesla electric cars will also affect the team's ability to learn the system. Once vehicles have escaped the potential danger, they can communicate with each other to share this danger, to prevent other vehicles from accidents here, and the accuracy of the sensors will be greatly improved.
This also explains why Tesla is eager to move to radar systems. Previously, Musk said that the radar system is more sensitive, it is easy to falsely report that causing the vehicle brake too much affect ride comfort. However, the upgraded radar system greatly reduces the probability of false alarms. Although Musk did not explicitly say, we can feel from his words that Tesla’s goal is to report false alarms less than once a year. Â
In addition to the above reasons, the Autopilot system can also use other advantages of radar. "After switching to the radar system, vehicles need not worry about bad weather such as rain, fog, snow, and dust," said Musk, who believes this is a major advantage of radar systems. “So even if the visibility is poor and there is a blockage in the line of sight, the radar can detect and advance the brakes in time.â€
In addition, the radar system has obvious advantages in detecting large metal objects (such as cars and trucks), but Musk admits that its detection in front of fluffy objects will deteriorate. This means that when you meet a moose or young deer crossing the road, the system will have a chance of making mistakes. However, due to the large size of the moose, it is easy for the radar to detect it. However, if you encounter the deer, you can only fight the character. Â
Another advantage of the radar is that it can look farther from the ground, unlike cameras that can only keep an eye on the front. “We are very confident with the radar system. It can see farther through the rebound effect, far beyond the limits of human vision. In this way, vehicles can brake in time to avoid accidents such as rear-end rear-end collisions.â€
This full package of dry goods will soon be rolled out in the United States, while other markets will also be gradually upgraded in the next 1-2 weeks.
