結論與建議

由選⼿及⾮選⼿騎乘結果可以歸納出,晃動程度是可以作為騎乘技術的判斷 指標,在主要晃動指標的數值上選⼿數值⼩於⾮選⼿,同時也從實驗結果得知,雖 然在滾筒訓練台騎乘時,⾃⾏⾞並不會向前移動,但由於⾃⾏⾞並沒有固定在訓練 台上,因此踩踏過程中產⽣的前後⽅向加速度會對加速規數值造成影響,且踩踏⼒

量也會影響騎乘過程中左右⽅向的晃動,因此如果需要透過晃動程度判斷騎乘技 術可能無法直接透過單⼀參數進⾏判斷,需要利⽤其他參數間相互搭配才能得到 較為精確的判斷依據。

從室外⼀般道路與室內開放式滾筒訓練台的結果可以得知,不論是慣性感測 去或者是胎壓變化,晃動指標參數在室外⼀般道路騎乘之結果都⽐室內開放式滾 筒訓練台還要⾼,造成這樣的原因與室外⼀般道路上的坑洞與減速條設計可能有 很⼤的關聯性,所以必須透過演算法將室外因路⾯所產⽣的異常值去除,因此在未 來實際應⽤⽅⾯,如何判斷路⾯異常值與處理會是必須更加深⼊探討的⽅向。

歸納以上結論,不論在室內或室外環境,騎乘的晃動程度是可以⽤於判斷騎乘 者的騎乘技術,但由於騎乘時的晃動是⼀種綜合多項因素的指標,因此仍然需要透 過多項數據以作為更加精準的判斷依據
