Abstract
In a first arousal level estimation device according to this invention, an initial residual setup unit sets a residual to be a reference of a driver, i.e., a residual with a smallest value during an initialization period as an initial residual among residuals calculated by a residual calculation unit during the initialization period from timing of starting an operation of a vehicle or timing of a change in a traveling scene including a condition of traveling road of the vehicle as a starting point till a predetermined period of time elapses. An arousal level estimation unit estimates a driver's arousal level based on a result of comparison between the initial residual set by the residual setup unit and the residual calculated by the residual calculation unit after the initialization period has elapsed. In this way, an estimation accuracy relating to a driver's state including a driver's arousal level is improved.
