奧迪A8自動駕駛黑科技逆天 正進行規模化的路測

Google無人車的工程師在路測時發現了一個問題——那些早期參與自動駕駛測試的人員，雖然承諾在路測時盯緊路況以便及時在緊急情況下接管駕駛——但其實很多人在路測時都不同程度分神去做各種各樣的事了。在自動駕駛圈內，這個經典的問題被稱為“脫手問題”。

因為脫手問題的存在，Google后來希望打造完全不需要人來駕駛，沒有油門、沒有剎車，也沒有方向盤的“全無人駕駛汽車”，福特、沃爾沃等車企也緊隨其后調整了自動駕駛研發路線。全天候、全工況無人駕駛汽車的研發和落地是漫長的，而在這之前，有一家車廠想用另一種方式解決“脫手問題”。這就是奧迪。

在7月的巴塞羅那，奧迪在官方的首屆品牌峰會Audi Summit上揭幕了全新一代的旗艦車型Audi A8。全新的Audi A8搭載Level 3的自動駕駛系統，其最亮眼的功能莫過于Traffic Jam Pilot，即當車速小于或等于37.3英里/小時，用戶可以啟動道路擁堵狀況下的自動駕駛功能。在當地法律允許的情況下，車輛會完全接管駕駛任務，直到系統通知用戶再次接管。這也是目前在全球范圍內，在實現量產的車型中擁有的最高級別的自動駕駛能力。

Traffic Jam Pilot是怎么回事？

即使作為一輛Level 3的自動駕駛量產車，奧迪在自動駕駛功能的設計上依然是比較克制的。

Traffic Jam Pilot啟動要滿足兩個條件：1. 車速小于等于37.3英里每小時（60公里每小時）；2. 車輛行駛在車道線清晰、雙向車道中央有隔離帶的主干道或者高速公路上。滿足這兩個條件后，Audi A8的儀表盤上會顯示“Traffic Jam Pilot準備就緒”這樣的提示，司機就能通過“Audi AI”按鈕開啟自動駕駛。

自動駕駛狀態下的A8接管了油門、剎車、轉向系統，可以在擁堵的主干道或者高速公路上，跟車、起步甚至變道，這時司機可以脫離方向盤完全放松下來。而當系統遇到新的情況，或者路況變好（車速超過37.3英里每小時）時，系統會留出8 - 10秒鐘的余量提醒司機接管駕駛：首先A8會通過儀表盤和語音發出提示，隨后車輛還會繼續收緊安全帶進行提醒，而后車輛會剎車逐漸減速，如果最終用戶仍然沒有接管，那么A8會減速停靠到路邊，并打開雙閃，解鎖車門。
