Abstract
A vehicle device or a vehicle estimation method estimates whether the driver is in an abnormal state different from a sleeping state by using a plurality of types of sensors, determines whether the vehicle is in a sleep-permitted automated driving or a sleep-unpermitted driving.

When determining that the vehicle is in the sleep-permitted automated driving, the device or the method reduces the plurality of types for estimation.
