Recently, Tesla can be described as a "problem", first because the speaker customization has been recalled in large quantities, and then because in South Korea due to exaggerated publicity battery performance was investigated, so that Tesla is on the cusp of the storm.
Recently, according to the Associated Press and Reuters reported on February 17, there are currently 354 complaints about Tesla's 'ghost brakes', and the NATIONAL HIGHWAY SAFETY ADMINISTRATION (NHTSA) has launched an investigation into Tesla.
Seeing this, there must be consumers who are very confused about the "ghost brake" mentioned above, why will they be complained about?
What is a "ghost brake"?
According to Reuters, NHTSA said that the vehicles surveyed are equipped with Tesla's advanced driver assistance system, that is, Tesla's Autopilot system, under this function, the vehicle can automatically complete the automatic braking and steering in the lane when driving, and other auxiliary driver operation functions, the biggest "effect" of this function is to reduce driving fatigue when driving long distances; at present, the industry is facing rapid development, and Tesla Autopilot has developed so far. It's been about 8 years.
NHTSA said that in the past 9 months, it has received a number of complaints about Tesla, when users turn on Tesla's autopilot assistance system, the vehicle suddenly and without warning automatic braking in the absence of brakes, this kind of unproven braking, consumers call it "ghost braking".
According to NHTSA, the current preliminary assessment, ghost brake complaints, covering the 2021-2022 Tesla Model 3 and Model Y models in the US market, all Tesla cars reviewed, are equipped with Tesla Autopilot; Tesla cars involved in the accident have also been confirmed, all turned on the Autopilot system or traffic perception cruise control, and most of the accidents occurred after dark.
Tesla's bizarre and bizarre events
At the beginning of 2021, there is a video in the short video platform burst into flames, a car owner will Tesla into the uninhabited cemetery, when driving, Tesla's auxiliary driving system in the visual port of the screen, even frequent detection of travelers, resulting in Tesla cars on the cusp of the storm, in addition, there are also netizens said that when driving in unmanned parking lots, the screen system will also detect the presence of pedestrians, so that the owner of the car to drive up the psychology is very panicked.
In this regard, many netizens said: Tesla's probe can detect ghosts, there is no need to make a fuss, and even some netizens said: Tesla is not a car for ordinary people at all, this is the "Lin Zhengying" can drive the car, netizens' brain holes, can be described as strange!
Why are there ghost events?
According to the previous introduction, most accidents occur after dark, as we all know, Tesla's driving assistance system research direction and many domestic companies are different, Tesla has been to the visual program as the final program research and development benchmark, so the camera plays a vital role in the assisted driving system, and the camera and sensor in the detection of similar obstacles, according to the auxiliary driving system, will be determined as an obstacle, so it will trigger the brake system.
And why accidents occur at night, the camera is like a human eye, the use of intuitive video and picture data as a reference modeling for assisted driving, and the domestic respect for the lidar is different, so, at night, the work efficiency of the camera will be greatly reduced, it is likely to be misjudged.
Write at the end
Assisted driving is still in the "developing" technology field, has not yet reached the upper limit of the function, but in the function that has been online, the occurrence of "supernatural events" is really not supposed, before the function is online, it must have undergone a lot of testing and data adjustment, especially the driving system, must ensure that there is no mistake, and Tesla's "supernatural pedestrian" event, it can still be judged that the appearance of pedestrians due to peripheral modeling will not have much impact on driving; but the "ghost brake" accident, but can not be ignored, just imagine, When driving at high speed, the sudden braking of the auxiliary driving system will certainly affect traffic safety, and even lead to accidents such as serial rear-end collisions, so it is hoped that NHTSA can correct Tesla's system bugs and ensure the safety of consumers.
