为设计针对驾驶人不同疲劳状态的预警方案,本文建立了包括察觉性、理解性和接受性的评价体系,系统研究了听觉、视觉和触觉3种预警方式对处于不同疲劳状态的驾驶人的预警效果。研究结果表明,各种预警方式对处于不同疲劳状态下的驾驶人具有不同的预警效果。听觉方式较适合于轻微疲劳状态,而触觉方式则更适合于非常疲劳状态。据此最终提出了一种适应于驾驶人不同疲劳状态的复合预警方案。
In order to design a warning approach for different level of driving person fatigue,an evaluation system is established regarding perceptibility,comprehensibility and acceptability.The effects of auditory,visual and tactile warnings on driving persons with different level of fatigue are systematically studied.The results show that different ways of warning have different warning effects on driving persons in different states of fatigue.Auditory warning is suitable for light fatigue,while tactile warning is more suitable for heavy fatigue.Based on these,an adaptive warning scheme is finally proposed suiting to driving persons with different level of fatigue.
