Tesla car blows up child doll

The state of Tesla’s driving test conducted this year was posted on Twitter, and it has become a hot topic with more than 100,000 likes.

In the video, a test pattern is filmed to see if the Tesla Model 3 can detect and stop a child-like doll placed in front of the vehicle while it is running.

While the Lexus RX, which is being tested at the same time on the right side of the image, stops firmly, Model 3 blows the doll away.

Is it because it is not equipped with “LiDER”?

Some people argue that the reason why the Model 3 could not stop in front of the doll was because the quality of the child doll was low, despite the bright and clear conditions, but it does not have a sensor called “LiDER”. It is said that this is the reason.

LiDER is a type of sensor that is said to be indispensable for realizing advanced autonomous driving.

Last May, Tesla announced that it would discontinue radar sensors like LiDER from driving assistance functions, including autopilot, in the “Model 3” and “Model Y” manufactured for the North American market.

Other manufacturers generally use both cameras and sensors to detect objects, but Tesla says that it detects only with cameras and Teslavision (neural network processing). This is also the policy of Tesla CEO Elon Musk, who said, “Humans use their eyes and brains to recognize space. says.

The advantage of abolishing LiDER is that production costs can be significantly reduced, so vehicles can be provided at low prices.

Since these autonomous driving technologies and driving support functions are still in the development stage, it is not yet clear whether it is correct or not to not use LiDER.

Autonomous driving function should be considered only as an aid

Autonomous driving technology is becoming a reality with the advent of the latest technologies such as steer-by-wire and LiDER. Level 3 automated driving has already been realized in commercial vehicles, and some experimental vehicles are equipped with level 4 to 5 automated driving.

However, at present, all manufacturers are still at the stage of trial and error, and it is dangerous to overestimate their performance. We still have to keep the state where the driver himself can steer at any time.

Although it is a very convenient automatic driving technology and driving support function, it seems to be good to think about it to the extent of “assisting the driver”.
