1. An apparatus comprising:
an interface configured to receive a plurality of sensor signals from a vehicle platform of a vehicle and present one or more control signals to the vehicle platform; and
a control circuit configured to (i) detect whether an attention state of a driver is in an attentive state or in one of a plurality of inattentive states, in response to one or more of the plurality of sensor signals received from the vehicle platform during a first window having a first duration, (ii) assess, for each respective one of the plurality of inattentive states, whether the driver is sufficiently attentive by monitoring the one or more of the plurality of sensor signals from the vehicle platform and determining whether a number of changes from the attentive state of the driver to the respective one of the plurality of inattentive states, during a second window having a second duration that is longer than the first duration, exceeds a respective threshold, and (iii) based on at least one of the respective thresholds being exceeded, transition operation of the vehicle to the driver and safely discontinue an automation system function of the vehicle.
