Abstract
A driving consciousness estimation device includes a driving readiness degree estimation unit configured to estimate a driving readiness degree relating to a driving consciousness of a driver based on a reaction time or a width of field of view of the driver and at least one of a time duration of eye glance away from road environment and an arousal level of the driver. An influence of the reaction time or the width of the field of view on the driving readiness degree estimated by the driving readiness degree estimation unit is greater than an influence of at least one of the time duration of eye glance away from road environment and the arousal level on the driving readiness degree.
