[ti:US: Nearly 400 Crashes of Driver-assist Vehicles] [by:www.51voa.com] [00:00.00]更多听力请访问51VOA.COM [00:00.04]A U.S. highway safety agency says Wednesday [00:04.98]that automakers reported nearly 400 crashes of vehicles with driver-assist systems. [00:13.64]Of those accidents, 273 involved vehicles from Tesla. [00:20.68]The National Highway Traffic Safety Administration, or NHTSA, [00:27.00]said the numbers should not be used to compare automakers. [00:32.32]The agency said it did not measure them by the number of vehicles [00:36.95]from each manufacturer that uses the systems, [00:40.99]or how many kilometers those vehicles traveled. [00:45.88]Automakers reported crashes from July of last year [00:50.70]through May 15 under an order from the agency. [00:55.80]It is examining such crashes overall for the first time. [01:01.72]Steven Cliff is head of the agency. [01:04.92]He said, "As we gather more data, [01:09.08]NHTSA will be able to better identify any emerging risks or trends [01:16.63]and learn more about how these technologies are performing in the real world." [01:23.32]Tesla's crashes happened while vehicles were using driver-assist systems [01:29.40]that have some control over speed and steering. [01:34.20]The company has about 830,000 vehicles with the systems on the road. [01:41.24]The next closest of the more than ten automakers that reported crashes was Honda, with 90. [01:50.00]Honda says it has about six million vehicles on U.S. roads with such systems. [01:57.52]The automaker Subaru followed with 10, and all other automakers reported five or fewer. [02:06.20]In a June 2021 order, [02:09.16]NHTSA told more than 100 automakers and automated vehicle tech companies [02:16.76]to report serious crashes within one day of learning about them. [02:22.96]They also told them to share information [02:25.58]about less-serious crashes by the 15th day of the following month. [02:32.44]The agency is examining how the systems perform and whether new measures may be needed. [02:40.04]NHTSA also said that six people were killed in the crashes [02:45.84]involving driver-assist systems, and five were seriously hurt. [02:52.16]Of the deaths, five occurred in Teslas and one was reported by Ford. [02:59.08]Three of the serious injuries were in Teslas, while Honda and Ford each reported one. [03:06.96]Tesla's crash number may appear higher because it uses technology to follow its vehicles [03:14.06]and gets real-time crash reports. [03:18.32]Other makers do not have such systems, [03:21.75]so their reports may come slower, or crashes may not be reported at all, NHTSA said. [03:31.00]Tesla has not answered a message from The Associated Press seeking comment. [03:37.44]Although Tesla calls it driver-assist systems "Autopilot" and "Full Self-Driving," [03:43.37]the company says the vehicles cannot drive themselves [03:47.25]and the drivers must always be ready to take over. [03:52.00]Manufacturers were not required to report [03:55.24]how many vehicles they have on the road that have the systems, NHTSA said. [04:02.52]The agency added they do not have to report how far those vehicles traveled, [04:08.05]or when the systems are in use. [04:11.76]An agency official said at present, those numbers are not known. [04:17.72]However, NHTSA may seek such information later. [04:24.36]In the meantime, the new data has enabled it to find out about crashes much faster than before. [04:32.68]At present, it is using the crash data to look for trends [04:37.02]and discuss them with the companies, the agency said. [04:41.64]Already, NHTSA has used the data to seek a recall, [04:47.17]open investigations and provide information for existing studies, officials said. [04:55.48]Also, they said it is difficult to find out how many drivers actually use the technology. [05:03.28]The Alliance for Automotive Innovation represents most automakers. [05:09.68]It said the data collected by NHTSA [05:13.68]is not enough by itself to evaluate the safety of automated vehicle systems. [05:21.04]NHTSA's order also covered companies that are running fully automated driving systems. [05:29.68]Vehicles with fully automated driving systems are only running in limited areas. [05:35.81]And they are not available for purchase. [05:40.04]Alphabet's self-driving car unit Waymo [05:43.48]reported 62 crashes involving vehicles with fully automated driving systems. [05:51.16]And General Motors' Cruise had 23. [05:55.96]Overall, the companies reported 130 crashes involving their fully automated vehicles. [06:04.16]In 108 of the crashes involving such vehicles, [06:08.88]no injuries were reported, and there was only one serious injury. [06:15.40]In most of the crashes, vehicles were hit from behind.
