A Relationship of Dependent Proneness for Driving Assistance by Auditory Information and Sensation Seeking Scale

摘要

With an improvement of the car electronics, many driving assist systems are introduced one after another, and recently, some are developed with the aim of taking over an attention owed to a driver. In such cases, experience of assisted drive could yield the risk of driver's inattention caused by dependence on the assist. In this study, an experiment using a driving simulator was conducted to investigate experience and dependency for driving assistance by auditory information. The result reveals that deterioration in the reaction to unpredictable absence of the assistance alarm, such as a miss or delay of an avoidance maneuver, is significantly induced, especially when a driver is posed by intense workload. And, influences of dependency on driving assistance varied individually. Specifically, a dependent proneness seems to have a relation to Sensation Seeking Scale.
