In May of last year, a Tesla electric car in the United States under the automatic driving mode, the accident of catching a big truck crashed, causing doubts about "auto-driving" and letting Tesla's advanced technology fall into an unprecedented crisis. However, after the incident was investigated by the National Highway Traffic Safety Administration (NHTSA), it finally returned to Tesla!
The NHTSA investigation report pointed out that during the accident, the AEB (Automatic Emergency Brake) device and the automatic driving system were not found to have any performance or design defects. Because the situation at that time was too special, the truck trailer was difficult. It is recognized that even if it is manually driven, it is difficult for humans to find a crisis, so the official believes that the accident cannot be attributed to the computer.
The data in the survey report also shows that the "Autosteer" function on the Tesla car can actually reduce the accident rate by 40%. After the results, Tesla CEO Elon Musk posted a message on Twitter, briefly excerpted this paragraph, and did not make other comments, but for Tesla, this is undoubtedly the best "security propaganda."
The photoelectric switch is the abbreviation of the photoelectric proximity switch. It utilizes the shielding or reflection of the light beam by the detected object, and the circuit is connected by the synchronization loop to detect the presence of the object. The object is not limited to metal, all objects that can reflect light (or block light) can be detected.
