Abstract
An apparatus comprises an interface and a control circuit. The interface may be 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. The control circuit may be configured to (i) detect whether an attention state of a driver is in an attentive state or an inattentive state in response to one or more of the plurality of sensor signals from the vehicle platform during a first window having a first duration, (ii) assess 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 changes in the attention state of the driver during a second window having a second duration that is longer than the first duration exceeds a threshold, and (iii) when the threshold is exceeded, transition operation of the vehicle to the driver and safely discontinue an automation system function of the vehicle.
