防眩目车内后视镜反射比的确定

Determination of Reflecting Ratio of Glareproof Interior Rear-View Mirror

尾随车的灯光通过车内后视镜对汽车驾驶员的眩目现象，是导致交通事故的隐患之一。防眩目后视镜的研制，是当今汽车安全性研究的一项课题。本文介绍了有关人体试验的结果，确定出车内后视镜在非防眩状态下的最小反射比限度，以保证驾驶员观察车后景物的后视性；确定出车内后视镜防眩状态的最大反射比限度，以保证驾驶员不致眩目、不致影响观察前方景物。还确定出后视镜两种工作状态变换时间的最大值。

Motor vehicle drivers are often glared by the Iamplight come from behind vehicles and reflected by interior rear-view mirror of their own vehicles, it might be one of the hidden dangers causing traffic accidents. Hence the development of a glareproof rear-view mirror recently becornes a necessary project in studying motor vehicle safety. Based on the results of human body tests, this paper describes the determination of a minimum reflecting ratio limit of interior rearview mirror without glare-reducing measures, for ensuring the drivers to be able to observe the views behind vehicles clearly; and the determination of a maximum reflecting ratio limit of glareproof rear-view mirror for ensuring the drivers not to be glared and not to obstruct them to observe the views ahead,and also the determination of the longest changing time in both operating conditions of rear-view mirror mentioned above
