A Study of Driver Attention Management Method for Listening Warning Sound in Using Voice Operation System

Abstract

The warning sound of the driver assistance system has become more and more important for safe driving. However, the auditory stimuli response time of the warning sound with a sound expression may be longer while using the voice activation system. The purpose of this study is to clarify the parameters for estimating the auditory stimuli response times of warning sounds with sound expressions in the case of using the voice activation system while driving and verifying the effects of the visual presentation of predicted auditory stimuli response times. As a result of our two experiments using a driving simulator, the first frequency standard deviation of the steering angle estimated the auditory stimuli response time for the warning sound. Moreover, the auditory stimuli response time was shown to be closer to the results of concentrating on driving conditions with the visual stimuli color change based on predicted auditory stimuli response times and the sense of anxiety when driving.
