Recently, Tesla announced that the radar sensor will be removed in the “AutoPilot” in the L3-level automatic driving level, triggering the industry dispute.
Despite Tesla announced the goal of building only the automatic driving system equipped with only an optical camera, there are also many sounds in the automotive industry to question whether it can cope with the night, glare, bad weather and other driving environments.
Of course, so far, Tesla’s models are still in the industry in the industry in pure electric vehicles. Due to Tesla’s corporate value is higher than any other car manufacturer in the world, consumers’ expectations and concerns are also increasing.
Since May, Tesla used for “Model 3” and “Model Y”, only 8 no radar The camera consists of. The image captured by the camera is transmitted through the computer network to identify and analyze the circumstances around the vehicle. 
Tesla has been viewing different views on radar applications. In May 2016, Tesla’s “Autopilot” system failed to detect a serious collision accident in front of a white trailer, causing the driver to die. Later, Tesla announced that it was planned to increase radar for automatic driving, but at the same time pointed out that some radar systems failed and needed to adjust.
Elon MIDDOT; Mask said in 2016: “The benefits of radar are different from the laser radar, even in the rain, In the harsh weather such as snow, fog and dust, you can also check the surrounding environment. “He added. Laser radar is an optical sensor technology that uses lasers to measure the shape of the object or the distance from the object, which provides more accurate than radar, but Due to cost, Tesla is not used.
Tesla also expressed dissatisfaction with the accuracy of radar, saying that there is a phenomenon called “phantom braking”, that is, the vehicle suddenly stopped when the crush or overpass. Elon Middot; Mask emphasized that only the automatic driving system consisting of the camera is safer than the radar because it causes less confusing.
2016After May, Tesla, also had similar accidents during automatic driving, and the National Highway Traffic Safety Administration (NHTSA) is currently investigating 24 accidents related to Tesla.
Most automotive manufacturers and automatic driving technology development companies are developing the automatic driving system of radar and laser radar using radio waves using optical cameras. .
Radar system, such as a camera, relatively inexpensive, low cost. In addition, it can be used in harsh weather to accurately identify the resolution of the object. In the case of laser radar, it has high resolution by using laser, but cannot be used under harsh weather. At present, most automatic driving system developers are integrating these three systems to make up for the shortcomings of each other.
However, in terms of Tesla, they claim to use the camera’s system to further development space because it can build an automatic driving system more enhanced than using expensive laser radar systems.
Some people are worried about building a system that only the camera, because there is no radar, the identification function under harsh weather is greatly reduced, and it is said to be in heavy rain The automatic driving function will stop in the case. It is also seen as a means of simply reducing the price of vehicle. In addition, when the obstacle is about to collide, the emergency braking function is also required to activate the emergency braking function, because the radar is excellent in measurement distance.
Tesra said that some automatic driving functions, such as techniques that maintain synchronous with the front vehicle, may be temporarily limited, but will be solved by software updates in a few weeks. Elon Middot; Mask also argued that Tesla’s camera system has been steadily improvement, so it is no problem with the radar.
The US National Highway Traffic Safety Administration first announced that some driving assistance features of “Model 3” and “Model Y” will omit Security proposal “check mark”. The “Consumer Report” “Consumer Report” in the US authority magazine also said that Model 3 wasExclude outside of the best recommendation. NHTSA and consumer reports are planned to use new test methods for Tesla’s new system.
