AutoBeta(AutoBeta.net)03/15 Report--

Since the birth of autopilot, there have been all kinds of disputes, among which the most controversial is its safety. In recent years, self-driving accidents have emerged one after another, all of which have exposed their drawbacks and hidden dangers.

In 2016, a US owner of Tesla Model S collided with his car in front of him while using autopilot mode, resulting in the driver's death on the spot. Later, after investigation, it was found that the car owner turned on the Autopilot function when the accident occurred. At that time, a large American container truck was crossing the road at the intersection. At this time, Model S is driving in the lane, on autopilot and nearly perpendicular to the truck. But at this time, due to the misjudgment of Tesla's Autopilot system, Model S crashed into the truck and got under the car without any deceleration. But Tesla's explanation is that neither the Autopilot system nor the driver noticed the white side of the heavy truck, so they did not hit the brakes, while Tesla explained that the high body of large trucks, in special road positions, and rare circumstances led to Tesla's misjudgment of Autopilot.

Coincidentally, this kind of thing also happens in China, when a rear-end collision occurred in the Hebei Handan section of the Beijing-Hong Kong-Macao Expressway in China. The cause was that a Tesla car that had started autopilot directly crashed into a road sweeper that was working, and the driver of Tesla was killed unfortunately.

On the evening of March 18, 2018, a self-driving car used for testing in Uber collided with a pedestrian in Arizona. The pedestrian was certified dead after being sent to hospital. According to the National Transportation Safety Board, the vehicle was under computer control at that time, and although there was a driver on board, the tragedy occurred.

And.

These gory safety accidents make people seriously doubt self-driving technology. it is understood that self-driving cars rely on artificial intelligence, visual computing, radar, monitoring devices and global positioning system to cooperate, collect road information through high-precision cameras and radar, input images and radar information into the vehicle computer, and then the computer calculates The computer program calculates according to the image and radar information, and then controls the operation of the vehicle so that the computer can operate the motor vehicle automatically and safely without any human initiative. But for now, autopilot is still in a relatively "primitive" state, that is, machines imitate human beings.

Judging from the current level of autopilot, more technical breakthroughs are needed to achieve it, and it is not yet possible whether autopilot can fully achieve the desired goals in the future, but according to the current situation, the research and development of autopilot really has a long way to go.
