重機煞車的方法... - 重機

參考一下這篇

"Downshifting During Emergency Braking"
http://www.msgroup.org/forums/MTT/topic.asp?TOPIC_ID=4897
重點摘要
..another even more important reason that you should NOT downshift while
emergency braking. It takes mental effort and focus away from what may well
be a life saving concentration on controlling your motorcycle during an
emergency braking maneuver - a distraction when you simply cannot afford any
distractions.

然後他附了一張圖表 出自"the Federation Motorcycliste Du Quebec in 2004"

專業車手的緊急煞車測試
(clutch usage had on 77 emergency braking stops performed by professional
riders)

(100 - 0 km/h)
測試次數 煞車G力 煞停距離 (m) 煞停時間 (s)
降檔 31 -0.891 43.17 3.21
不拉離合器 35 -0.889 41.51 3.21
拉離合器 11 -0.929 39.95 3.08

這篇則提供另一個的說法
"請一定要邊緊急煞車邊退檔"
但他的理由是因為當你緊急煞車完之後如果在一檔 可以趕快加速逃跑 XD
以避免被後面(緊急煞車)(的車)撞上

但就我所查的資料跟物理解釋而言
若是要求「最短煞車距離」
最好的方式還是不要分心退檔
