We Crash Four Cars Repeatedly to Test the Latest
Automatic Braking Safety Systems

2018年11月的文章
測試車款:
Cadillac CT6
Subaru Impreza
Tesla Model S
Toyota Camry
1. 接近前方靜止車體

2. 前方車輛切車道,目標車輛變成靜止物體

3. 比較ACC、AEB與駕駛踩煞車三者最大減速度
https://i.imgur.com/rnyLzQw.jpg
4. 接近前方慢速(10 mph)車輛
https://i.imgur.com/k8k9vXm.jpg
可以看出依目前市售車配置的ADAS系統,遇到前方靜止或低速目標物
能煞住避免追撞的車速不超過50mph
很大原因是車輛蒐集的數據量受限於硬體能力
毫米波雷達的偵測距離與攝影機的有效辨識距離
不只雷達要偵測到,還得根據攝影機數據辨識出前方靜止障礙物(車)
加上系統即時執行決策(閃避或急煞
再來,關於自駕排名,目前最有公信力的還是這篇報告
Navigant Research Leaderboard Report: Automated Driving
2017版本

2019版本

2019的完整報告我沒有,所以只能拿手邊2017版的報告來看

VW

Tesla

TOYOTA

Honda

可以看到Tesla在技術項的評分非常低,以下是對Tesla的完整評論
https://i.imgur.com/iJxEnoZ.jpg
Navigant Research believes that the current Tesla Autopilot 2 system will
likely never be capable of Level 5 automation, and even Level 4 is likely
to be more limited than other systems.
對照目前有取得美國州政府核准自駕車自人服務的公司
以下兩則是2018~2019的新聞
經歷人事地震後的 Zoox,獲准在加州提供自動駕駛叫車服務
http://technews.tw/2018/12/25/zoox-self-driving-cars-license/
Waymo 的全自動駕駛汽車開始在鳳凰城接載乘客

Waymo Dataset Lidar Visualization (Lidar視覺化)
https://www.youtube.com/watch?v=G0MDV-IUzjk
Tesla官網提到"目前車上現有的硬體配備可滿足未來全自駕"
https://i.imgur.com/7Ci6wSb.jpg
Musk的推特內容
https://i.imgur.com/7c6b2hj.jpg
Tesla目標今年2020年實現全自駕,並推出Robotaxi無人駕駛計程車
但以現有車上搭載硬體配備,僅憑更新演算法軟體達到全自駕
請問這目標是不是牛皮吹大了點?????
