※ 引述《DYE (跟腦殘爭最後都會變腦殘.)》之銘言:
: 先上行車記錄器圖
: https://tinyurl.com/y8udsb8u
: 這是台美製Model3 並且加購FSD
: 車主稱 當時開著AP 遇砂石車硬插
: 車子卻加速撞上去造成損傷
: 事後 車主要求特斯拉解釋
: 為何沒識別砂石車並加速撞上去
: 特斯拉表示該車FSD硬體並無故障
: 數據也無異常
: 交涉無果 上網討拍
: 我猜
: 大概是特斯拉看比亞迪電動砂石車不爽
: 敢插線,才撞上去
: 不過要撞贏很難

這類無法有效辨識撞上貨車的案例發生過不少起
例如上個月在台灣,國道上特斯拉直接撞上橫躺的小貨車
看一下2018年發生在美國,Tesla追撞靜止消防車的案例
NTSB調查結果

事故原因為駕駛疏忽,Tesla在最後的3分多鐘並沒有偵測/提醒駕駛握方向盤
而在碰撞前3~4秒前方車輛換道後
Tesla並未感測到前方靜止的消防車,反倒加速
直到碰撞前0.49秒Tesla才開始警示,此外AEB系統也沒有作動
https://i.imgur.com/7952UcL.jpg
AEB需要radar和camera同時觸發
另外在NTSB調查報告出來後,Brad Templeton撰寫的一篇文章

And It's Not Pretty For FSD

硬體(感測器)的應用與限制
Radar:
1. 道路環境有柵欄、標示牌等靜止物,雷達不能因為辨識到這些靜止物就選擇煞車
2. 因反射面角度問題,反射的訊號會變弱
(另外像遇到大型貨車側面的case,雷達打的角度沒那麼高可能也偵測不到)
Camera:
1. 當目標傾斜一個角度時,可能辨識不出來
2. 立體攝影機可以解決辨識問題,但Tesla未採用
總之,類似事故是駕駛人疏忽,車輛也未即時發出警訊要駕駛人專注
加上車上現有硬體(感測器)的感測能力限制導致的情況
但對比Tesla官網或Musk說法.....不覺得哪邊怪怪的嗎?
Tesla官網提到"目前車上現有的硬體配備可滿足未來全自駕"
