探討狹窄可傾車輛之自動傾斜機制對駕駛績效及駕駛反應的影響

Abstract

狹窄可傾車輛 (Narrow Tilting Vehicle, NTV)是一種新型態的個人行動概念車，可以解決能源短缺及交通壅塞等問題。然而此新興車輛之自動側傾特性會影響駕駛者的駕駛作業，造成其駕駛反應改變、駕駛績效降低，因而導致意外發生。因此本研究透過駕駛模擬器的實驗來了解NTV自動側傾機制影響駕駛者作業的情形，進而幫助NTV的設計以降低駕駛者可能肇事的機會。研究結果發現，NTV的側傾角度及彎道的特性皆對駕駛績效及駕駛反應有顯著影響，並且傾斜角度越大、彎道的彎度越大時，越有可能會產生車輛碰撞。建議NTV側傾機制的設計上，在側傾角度足以對抗翻覆之餘，應使用最小之傾斜角度。而NTV較適合行駛於彎度較小的道路，若是必須經過大幅度或是連續的彎道，則應減速行駛以確保行車安全。

Narrow Tilting Vehicle (NTV) is one kind of new style personal mobile vehicles. It can solve the problems about energy shortage and traffic congestion. However, the automatic tilting feature of NTV may affect drivers' tasks and decrease their driving performance. These problems result to traffic accidents. Therefore, this study examined the effect of the NTV’s automatic tilting mechanism on the drivers’ task through driving simulator experiment. The results indicated that tilting angle of NTV and the curve of road affected driving performance and driving response significantly. Both the bigger tilting angle and curve caused more vehicle collisions than smaller ones. Eventually, the study recommended that the smaller tilting angle should be considered when designing the NTV tilting mechanism. Moreover, NTV was more suitable to travel through the smaller curve.
