一 | 8 月 26 日消息,“绿色地狱”纽博格林赛道是车手证明实力、刷新圈速纪录的圣地。不过,越来越多的汽车制造商开始将纽博格林视为自动驾驶技术的试验场。小米在今年夏天率先展开尝试,一辆搭载自动驾驶技术的小米 YU7 GT 用 10 分 29.483 秒完成了一圈,达成全球首个纽北自动驾驶圈速纪录。这个成绩比人工驾驶的同款车型慢了 3 分多钟,但对于一辆自动驾驶汽车来说,这样的表现已经相当不错。 CANBERRA, Australia -- Australian journalist Cheng Lei says she spent more than three years in detention in China for breaking an embargo with a television broadcast on a state-run TV network.Cheng‘s first television interview since she was freed was broadcast in Australia on Tuesday almost a week after she returned to her mother and two children, aged 11 and 14, in the city of Melbourne.The Chinese-born 48-year-old was an English-language anchor for state-run China Global Television Network in Beijing when she was detained in August 2020.She said her offense was breaking a government-imposed embargo by a few minutes following a briefing by officials.Her treatment in custody was designed to “drive home that point that in China that is a big sin,” Cheng told Sky News Australia. “That you have hurt the motherland and that the state’s authority has been eroded because of you.” “What seems innocuous to us here is –- I’m sure it’s not limited to embargoes, but many other things -- are not in China, especially (because) I’m given to understand that the gambit of state security is widening,” she said.Cheng did not give details about the embargo breach.Her account differs from the crime outlined by China’s Ministry of State Security last week.The ministry said Cheng was approached by a foreign organization in May 2020 and provided them with state secrets she had obtained on the job in violation of a confidentiality clause signed with her employer. A police statement did not name the organization or say what the secrets were.A Beijing court convicted her of illegally providing state secrets abroad and she was sentenced to two years and 11 months, the statement said. She was deported after the sentencing because of the time she had already spent in detention.Observers suspect the real reason Cheng was released was persistent lobbying from the Australian government and Prime Minister Anthony Albanese’s planned trip to China this year on a date yet to be set.Cheng said that a visit to a toilet at the court on the morning before she was sentenced was the first time in more than three years that she had sat on a toilet or seen her reflection in a mirror.Her commercial airline flight from Beijing to Melbourne was the first time she had slept in darkness in three years because the lights were always left on at night in the detention facilities.Cheng migrated to Australia with her parents at age 10. She said she struggles to answer when asked how she has been since her return.“Sometimes I fell like an invalid, like a newborn and very fragile,” Cheng said. “And other times I feel like I could fly and I want to embrace everything and I enjoy everything so intensely and savor it.”。

二 | 如今,梅赛德斯-AMG 似乎也准备加入这一行列。近日,谍照摄影师拍到一辆 GT 63 原型车正在进行测试。乍看之下,这辆车与普通车型并没有太大区别,但车顶上安装了三个传感器。此外还可以看到,车内“驾驶员”特意将双手放在方向盘之外。据谍照摄影师透露,这辆原型车首先以非常缓慢的速度沿着赛道最右侧行驶,用于完成赛道的圈速测试和地图采集。整个过程大约耗时 25 分钟,随后车辆又切换到赛道最左侧,重复进行圈速测试和地图采集。在确定赛道两侧边缘的位置后,这辆原型车终于做好了完全脱手驾驶的准备。第一次自动驾驶正式跑圈时,车辆完成了一个“非常缓慢且谨慎的圈”。据报道,车辆整体驾驶风格十分保守,加速受到严格控制,并且会提前进行制动。这一圈耗时不到 20 分钟,车内“驾驶员”全程只是为了在出现问题时进行干预。成功完成测试后,车辆返回维修区,让工程师分析采集到的数据,并进一步调整车辆的相关设置。随后,这辆原型车再次驶上赛道进行第二圈测试,完成时间比第一圈“快了几分钟”。不过,据报道,这一成绩“距离小米创下的纪录还差得很远”。据了解,梅赛德斯-AMG 似乎在完成第二次测试后暂时结束了此次测试。不过毫无疑问,该公司将仔细分析这次测试获得的数据,并从中总结经验。预计这辆原型车未来会再次出现在纽博格林赛道,并尝试创造属于梅赛德斯-AMG 自己的自动驾驶圈速纪录。
