上次，雷鋒網編輯剛問完中國破解特斯拉第一人劉健皓今年還搞不搞特斯拉，今天（3 月 29 日），360 的老對手騰訊科恩實驗室馬上宣布了特斯拉 Autopilot 三個實驗性安全研究成果。這也是繼 2016 至 2018 年連續(xù)發(fā)布針對網聯汽車安全研究成果后，騰訊科恩實驗室首次發(fā)布對量產車型高級輔助駕駛功能的實驗性安全研究成果。

成果一：雨刷的視覺識別缺陷

特斯拉 Autopilot 系統(tǒng)借助圖像識別技術，通過識別外部天氣狀況實現自動雨刷功能?？贫鲗嶒炇彝ㄟ^研究發(fā)現，利用 AI 對抗樣本生成技術生成特定圖像并進行干擾時，該系統(tǒng)輸出了“錯誤”的識別結果，導致車輛雨刷啟動。

成果二：車道的視覺識別缺陷

特斯拉 Autopilot 系統(tǒng)通過識別道路交通標線，實現對車道的識別和輔助控制?？贫鲗嶒炇彝ㄟ^研究發(fā)現，在路面部署干擾信息后，可導致車輛經過時對車道線做出錯誤判斷，致使車輛駛入反向車道。

成果三：遙控器操控車輛行駛

特斯拉 Autopilot 具有保持在車道內行駛，自動變換車道等功能。在對 Autopilot 進行安全研究及測試后發(fā)現，利用科恩實驗室發(fā)現并報告的 Autopilot 漏洞（版本2018.6.1），在特斯拉Model S上獲取 Autopilot 控制權之后，可實現第三方遙控裝置對車輛行駛方向的操控。

總結下來，可啟動雨刷，可誤導車輛方向判斷，可操控行駛方向！

雷鋒網注意到，特斯拉已對上述研究成果反饋：

特斯拉關于科恩實驗室“雨刷的視覺識別缺陷”（成果一）的反饋

“This research was demonstrated by displaying an image on a TV that was placed directly in front of the windshield of a car. This is not a real-world situation that drivers would face, nor is it a safety or security issue. Additionally, as we state in our Owners’ Manual, the ‘Auto setting [for our windshield wipers] is currently in BETA.’ A customer can also elect to use the manual windshield wiper setting at any time.”

特斯拉關于科恩實驗室“車道的視覺識別缺陷”（成果二）的反饋

"In this demonstration the researchers adjusted the physical environment (e.g. placing tape on the road) around the vehicle to make the car behave differently when Autopilot is in use. This is not a real-world concern given that a driver can easily override Autopilot at any time by using the steering wheel or brakes and should be prepared to do so at all times."

特斯拉關于科恩實驗室遙控器操控車輛行駛（成果三）的反饋

“The primary vulnerability addressed in this report was fixed by Tesla through a robust security update in 2017, followed by another comprehensive security update in 2018, both of which we released before this group reported this research to us. In the many years that we have had cars on the road, we have never seen a single customer ever affected by any of the research in this report.”

科恩還稱，自動駕駛相關技術的發(fā)展和落地不應受限于安全風險和問題。隨著圖像識別技術在汽車行業(yè)，尤其是在高級輔助駕駛和自動駕駛領域中的廣泛應用，產業(yè)上下游參與廠商需對安全性保持高度關注與投入。
