2021-08-25 12:16:47 Car home

  [ Car home New energy ]  Super broadcast , Every week . The hottest event this week must be Tesla's “AI DAY”, Develop supercomputers for autonomous driving 、 Automatic driving depends only on vision, not on radar, etc. it makes people wonder what Tesla has to do “ moth ”, Netizens also have praise and criticism on this matter . In addition, it is also assisted driving ,8 month 15 An obituary on the th once again sounded an alarm to users ―― Auxiliary driving , Also hold the steering wheel .

  8 month 14 Japan , A group called “ Meiyihao ” The official account of the individual is published by the obituary :2021 year 8 month 12 On the afternoon of Sunday 2 when , Founder of shangshanruoshui investment management company 、 Founder of yitongtianxia catering management company 、 Lin Wenqin, founder of meiyihao brand management company ( nickname “ Cute swordsman ”), Drive Wei to ES8( Parameters | inquiry ) The car enables the automatic driving function (NOP Pilot status ) after , A traffic accident occurred in the Hanjiang section of Shenhai Expressway , Unfortunate death , At the age of 31 year . At present, the cause of the accident is still under investigation , But this event pushed the safety of assisted driving to a climax .

   First of all, we express our deep condolences to the victims of the accident , We also hope that relevant departments will investigate the cause of the accident as soon as possible , Through the timeline below , You can also simply review the whole thing :

   In fact, about 8 month 12 The accident on the th , What we want to say is also very simple , On the one hand, it is for car enterprises , On the one hand, it is for users . Now a necessary publicity for many models is the ability of auxiliary driving , But now no mass-produced car on the market has reached “ Autopilot ” Ability , Are all “ Auxiliary driving ” Category , About definition , In the past two years, most car companies have not called it “ Autopilot ” 了 , Have a call “ Auxiliary driving ” Of , Have a call “ Automatic assisted driving ” Of , The same thing is “ auxiliary ” Don't lose the word .

   According to Wei Lai App Yes NOP Introduction to ,NOP It's the navigation system 、 High precision maps and NIO Pilot Deep integration of autopilot system , stay Pilot The cruise speed control function has been realized 、 Keep the gap 、 Based on the steering assist and turn signal control lane change function , Make vehicles in most Expressway and urban elevated sections covered by high-precision map , Automatically import into the main road according to the navigation path 、 Cruise on the main road and intelligently select the best lane 、 Automatically switch to the next Expressway according to the navigation plan / elevated 、 Functions such as automatic departure from the main road .

   At this stage, the auxiliary driving function is not enough to replace human drivers , Therefore, some car companies also clearly indicate in the function introduction and instructions for use : This is driving assistance , Unable to achieve automatic driving , The driver needs to be ready to take over the vehicle . But there are also some car companies in order to achieve the publicity effect , Constantly mentioned in assisted driving “ Automatic capability ”, Up to a point , This may also cause misunderstanding to users who first contact assisted driving . Therefore, it also advocates various car enterprises , Be sure to clearly indicate the of the auxiliary driving system to the user “ auxiliary ” attribute .

   To the client , Many users don't agree with the danger of driving , Even publish some on the Internet and let go , Let the vehicle “ Autopilot ” Pictures of the / video , With “ dangerous ” For beauty , For show off . Whether car companies or the media are testing 、 Users will be reminded when promoting assisted driving , When the vehicle starts assisted driving , The driver should always observe the road conditions , Be ready to take over the vehicle at any time , I hope all users can be vigilant , This is neither a joke nor a perfunctory cliche .

   In addition, when facing some special conditions on the road , Most assistive driving systems cannot make timely decisions 、 React correctly , For example, in the face of a sudden stoppage 、 Pavement construction 、 Cone barrel 、 Large curvature curve, etc , besides , Maybe there are more special road conditions that assisted driving can't handle , But not yet discovered . So even if the user turns on assisted driving and supervises , In case of special road conditions, do not hesitate to take over manually , Don't put your hopes on the auxiliary system .

Super broadcast comments :

   I think at this stage , The judgment ability of auxiliary driving system must be inferior to that of human drivers , I also believe in the future “ Autopilot ” The s , Cars can really drive safely on their own , But this is not now .


  8 month 20 Early in the morning , Tesla held as scheduled “AI DAY”( Artificial intelligence day ) Activities ( Develop supercomputing for autopilot tesla AI Daily explanation ), During the event, Tesla shared its progress in the field of automatic driving , And released a neural network supercomputer with computing power provided by independently developed chips Dojo And a humanoid robot .Dojo What does it have to do with autopilot ? Tesla rewrites Autopilot Arithmetic unit , Make them use their vision to observe the road conditions , and Dojo It's for learning 、 Calculation 、 Judge .

Why should Tesla be a supercomputer Dojo?

   Each car company has its own way to do automatic driving “ Schools ”, For example, the mainstream is through the camera 、 radar 、 Laser radar and other hardware for fusion sensing , But before that, Tesla CEO Musk said , He prefers visual perception . Today, Tesla models produced in the United States have abandoned radar and other sensing elements , Only the camera is used for automatic driving perception through continuous video images .

   The reason why the current mainstream “ Schools ” It's radar 、 Laser radar , The reason is that the shape of an object can be sensed by lidar , Use millimeter wave radar to sense the moving speed of objects / The trajectory . Tesla's current logic is that it can be built through video 3D scene , In this way, the vehicle also obtains the three-dimensional information of the environment , Vehicles can also identify hazardous elements . But how to make Autopilot The system has accurate judgment on the environment ? Now ,Dojo That comes in handy .

Dojo What is the specific use ?

  Dojo Will collect large-scale road driving pictures from the cameras of Tesla's models , For autonomous learning ,Dojo Will drive the truck... In a human like way of thinking 、 Pedestrians 、 Animals and other dangerous elements , And write the characteristics of dangerous elements into Autopilot Program , Make the vehicle to the scene on the road 、 Have a more accurate understanding of things , Tesla will also pass OTA Put the latest Autopilot Push the program to the vehicle . You can take Dojo Understood as a “ The brain of artificial intelligence ”, It can learn by itself 、 Mark 、 Judge 、 Keep evolving , So that Tesla's autopilot logic 、 The ability is more perfect .

   In many car companies , Collect road driving pictures 、 Marking data also exists , But without a supercomputer with super computing power , These tasks need to be marked by computers with limited computational power and people , inefficiency , So Tesla built Dojo.Dojo How strong the ability is ? According to the parameters published by Tesla , It has finally reached 1.1EFLOPS( Billions of floating-point operations per second ), The reading and writing speed is up to 1.6TBps, The performance of Fuyue supercomputer ranks first in the world 2.65 times ( The first Dojo The supercomputer will be produced and put into use next year ).

Dojo The value conjecture of

  Dojo What will it bring to Tesla ? First , With Dojo And a lot of road driving videos , Tesla can quickly improve Autopilot Visual perception of the system , Simply put, Tesla's Autopilot Will have more accurate judgment 、 Improve reliability . in addition , Many friends also know , At present, several pure electric vehicles have been considered to be equipped with lidar , But lidar is expensive , This undoubtedly increases the cost of vehicles , And Tesla has Dojo, It can realize higher-order automatic driving by pure vision , Minus sensing hardware , This is also a disguised reduction in vehicle costs .

   At the beginning, we said Tesla also released a humanoid robot ( be known as Tesla Bot), The robot is powered by a robot on Tesla FSD On board computers 、 The camera and 40 It consists of a micromotor , The future goal is to undertake manual labor and rescue tasks that human beings cannot complete . If you have the Dojo, I'm not sure Dojo Can undertake the task of training robots , But for the field of artificial intelligence , In my submission Dojo It must be of great value 、 There are many application scenarios .

Super broadcast comments :

   Tesla is “ The founders ”, At first, Tesla took the industry's auxiliary driving ability to a new level , New ideas have also been made in vehicle design . Now all car companies are trying to integrate 、 Development of lidar , But Tesla has made new ideas for pure vision solutions , This may be a new innovation , But what is the actual effect of application , Let's wait and see . For Tesla's plan , Netizens are also mixed , Have recognized Tesla's innovation 、 Some people questioned Tesla's unreliability , What do you think ?( writing / Car home You Dongqing )
