沒有雷達的特斯拉正式出海,為何馬斯克、Toyota發展自動駕駛都押注鏡頭技術?

特斯拉宣佈捨棄雷達近一年後,沒有搭載雷達的Model 3、Model Y如今也正式出海,銷往
歐洲、中東等市場。與此同時,Toyota也透露有意走特斯拉路線,依賴鏡頭發展自駕技術
。為何分別是汽車、電動車龍頭的這兩家企業,都選擇鏡頭作為自動駕駛未來方向?
逆業界趨勢而行,特斯拉為何捨棄雷達、光達
感測器是自駕車的靈魂之窗,被認為是保障乘客安全的重要基礎,一直以來絕大多數投入
自動駕駛的車廠,都是結合使用多種感測器,提供系統更全面的車輛周邊資訊。
然而特斯拉卻反其道而行,除了馬斯克自始至終反對光達,曾說「所有依賴光達的人都註
定失敗」外,2021年5月更進一步宣佈捨棄雷達,自駕技術的開發重心將全部放在鏡頭上
。
作為比較,Nvidia最新發表的自駕車平台,搭載14枚鏡頭、9個雷達、3個光達及20個超音
波感測器,建立多元、大量的感測器系統可說是業界方向。特斯拉與整個產業截然相反的
作法,當時也引發外界抨擊是罔顧駕駛生命,會影響自駕技術的安全性。
事實上,捨棄雷達後特斯拉也對新車做了一些調整,輔助駕駛技術Autosteer限速75公里
、更長的跟隨距離,並且夜間會自動開啟遠光燈,同時還暫停了部份功能。
但為何特斯拉仍要一意孤行,將所有籌碼押注在鏡頭上?
發揮汽車數量優勢,Toyota從鏡頭技術切入自駕技術
要理解特斯拉的決策,需要先了解光達、雷達等感測器的優劣所在。光達與雷達相較鏡頭
最大的優勢在於,他們能夠更為精準地測量距離,而雷達更能夠風雨無阻,不受外在惡劣
天候的干擾。
光達能夠利用光或雷射測量距離,然而價格高昂,在車輛上安裝光達系統的成本高達1萬
美元,大大影響自駕技術的門檻,且在惡劣天候下無用武之地,使它一直不受到馬斯克認
可。
無獨有偶,根據《路透社》報導,Toyota自駕子公司Woven Planet也決定要走與特斯拉類
似的路線,重點聚焦在運用鏡頭實現自駕技術。

特斯拉買方案應該是最省錢的做法
