A car accident will definitely happen. And there must be someone who unfortunately became the first dead person in a driverless car one day.
At 15:00 on May 7 this year, Joshua Brown, who drove Tesla Model 3, turned on the Autopilot, but unfortunately collided with the trailer in the driverless mode, dying on the spot. .
The autopilot system uses sensors and camera technology to detect possible obstacles in front of the road. However, in this accident, the system did not see the truck turning left in front of Brown's car, so there was no timely braking, which caused Tesla to drill directly under the truck and continue to slide until it hit two barriers. Sliding to the elevated south side stopped.
Currently, the US Highway Safety Administration (NHTSA) is investigating 25,000 Tesla Model S. If the Tesla autonomous driving system is ruled to be flawed, it will lead to a large-scale recall. This is undoubtedly a heavy blow to Tesla and technology madman Musk, and it will cast a shadow over the emerging unmanned technology.
However, does this accident and failure mean that we should no longer trust driverless cars?
Car accident: 130 million miles to 940 billion miles
The data shows that about 90 people die in car accidents every day in the United States. These are naturally cases of human autonomous driving. According to the NaTIonal Vital StaTIsTIcs Report released in February 2016, the number of people killed in a car accident in the United States in 2013 was 33,800.
Tesla also said in a statement that this was the first fatal accident in the Autopilot assisted driving system that drove 130 million miles, and a fatal crash occurred every 94 million miles in the United States.
There is no doubt that the autonomous driving system is not perfect and may never be perfect. But most experts believe that it has far more potential than human autonomous driving.
Autopilot system technology has proven to save lives. Most notably, safety regulators and major automakers agree that automatic brake technology for cars should be standard on all new cars. This automatic braking technology means that when the car automatically detects an obstacle in front of it, it will start the brakes to prevent the driver from reacting in time.
This automatic braking technology can avoid tens of thousands of lives that are dying every year from car accidents by avoiding dangerous car accidents. But no one has ever said that with these automatic technologies, there will be no more car accidents.
How to autopilot
Regarding the car accident, Tesla explained that the white truck is difficult to identify under the blue sky background, and from the perspective of Tesla Autopilot, the side of the trailer truck is suspended on the ground. This very rare situation leads to the Autopilot system. The negligence did not initiate automatic braking. At the same time, the collision position of the vehicle is Tesla's windshield, which makes the collision safety system unable to function, which directly leads to the death of the driver.
Red for Tesla, blue for truck
Tesla stressed in the statement that assisted driving technology is still developing and not perfect, requiring drivers to be vigilant. Therefore, in the process of using Autopilot, the car will constantly prompt the driver to put both hands on the steering wheel and be responsible for the vehicle.
At the same time, the high-speed section of Brown's car accident is also quite special. There were no traffic lights on the scene, and the vehicle was allowed to cross the lane for a big turn to the left. This is equivalent to the dangerous characteristics of both urban roads and highways. This situation is also a challenge for human drivers, especially for engineers who design autonomous vehicles.
In fact, today's cars have applied a lot of automation technology. When these automatic sensing technologies are combined with other technologies, they become a popular driverless mode. Therefore, the automatic technology is not mysterious. The whole unmanned system needs human cooperation and vigilance before it is fully mature.
For example, many vehicles today are equipped with lane keeping assist systems. This technology uses a camera to sense the lane on the road and then directs the car to the middle of the lane by a miniature electric motor connected to the steering mechanism of the car. But if the traces of the driveway are difficult to see or the lanes are not marked at all, the technique is completely useless.
In addition, when combined with the so-called "active cruise system", the car system can use cameras, radar and other sensors to detect vehicles in front of the road and always maintain a safe distance from the vehicle in front. In theory, this system allows the driver to step on the highway without stepping on the accelerator or stepping on the brakes.
Daimler's Mercedes-Benz and Nissan's luxury car brands Infiniti and BMW have provided these systems for today's cars. But the key to these systems is that the driver must always keep his hands on the steering wheel. If the driver's hand leaves the steering wheel, the vehicle will prompt to grab the steering wheel again after a few seconds, otherwise the system will automatically exit, forcing the driver to drive autonomously.
These systems have now matured quite well and are well used on highways and even in less smooth road conditions.
However, these systems are temporarily unable to meet the driving needs of urban roads or more complex road conditions. As a result, many automakers and technology companies are working hard to make autonomous vehicles work in cities.
The advancement of technology will not stop because of failure. BMW has recently taken the lead in setting a timetable, clearly stating that in 2021, autonomous vehicles suitable for urban traffic will be fully implemented. The mission will be completed in conjunction with Intel, the leading chip company, and Mobileye, an Israeli technology company with considerable weight in computer vision and machine learning.
KNLN6-63 Residual Current Circuit Breaker With Over Load Protection
KNLN6-63 TWO FUNCTION : MCB AND RCCB FUNCTIONS
leakage breaker is suitable for the leakage protection of the line of AC 50/60Hz, rated voltage single phase 240V, rated current up to 63A. When there is human electricity shock or if the leakage current of the line exceeds the prescribed value, it will automatically cut off the power within 0.1s to protect human safety and prevent the accident due to the current leakage.
leakage breaker can protect against overload and short-circuit. It can be used to protect the line from being overloaded and short-circuited as wellas infrequent changeover of the line in normal situation. It complies with standard of IEC/EN61009-1 and GB16917.1.
