探討狹窄可傾車輛對駕駛生理不適和駕駛績效的影響

Abstract

在現今都市化的社會中，都市人口稠密造成交通壅塞，且因為能源需求龐大又尚無開發出充足的新能源，使得能源短缺，為了減輕交通壅塞與能源短缺，交通工具也往小型化、機動化發展，狹窄可傾車輛(Narrow Tilting Vehicle, NTV)因而發展出來。但狹窄可傾車輛的駕駛環境不同於一般的車輛，為了探討其改變對於駕駛者的影響，本研究利用真實的狹窄可傾車輛去進行駕駛模擬，進而發現傾斜輔助系統會造成駕駛者生理不適程度加重，有別於一般駕駛者不會因為動態環境而產生不適的觀念，證實了狹窄可傾車輛的特性會影響駕駛生理不適。且駕駛者的生理不適程度對於駕駛績效有所影響，且因生理不適程度不同對駕駛績效的影響也有所不同，因此必須重視由於傾斜輔助系統所帶來的影響，在未來狹窄可傾車輛的研究不應該只著重在車身穩定性與機動性的發展，在開發傾斜輔助系統的同時應該也考慮到如何降低其對駕駛者的不良影響，使得狹窄可傾車輛的發展能更兼顧到安全、舒適的考量。

In the urbanized society, high population density causes traffic jammed. Besides, huge energy resources demand and lack of new energy resources exploration cause energy resources shortage. In order to solve these problems, the narrow and tilting vehicle (NTV) is developed. The driving environment of NTV is different from other cars. In order to explore the effect of different driving environment on drivers, the research uses a narrow and tilting vehicle simulator to simulate driving tasks. The results show that tilting auxiliary system affects drivers’ physiological uncomfort level. Besides, drivers’ physiological uncomfort makes driving proformance poorer. When tilt angle is small, the nausea scale scores correlates with total time of driving tasks. When tilt angle is large, the nausea and oculomotor scale scores correlate with car collision and deflection.
