摘要：In a first arousal level estimation device according to this invention, an initialresidual setup unit sets a residual to be a reference of a driver, i.e., a residual with asmallest value during an initialization period as an initial residual among residuals
calculated by a residual calculation unit during the initialization period from timing ofstarting an operation of a vehicle or timing of a change in a traveling scene including acondition of traveling road of the vehicle as a starting point till a predetermined periodof time elapses. An arousal level estimation unit estimates a driver's arousal level basedon a result of comparison between the initial residual set by the residual setup unit andthe residual calculated by the residual calculation unit after the initialization period haselapsed. In this way, an estimation accuracy relating to a driver's state including a driver'sarousal level is improved.
