VEHICLE OPERATOR MONITORING

A computer in a vehicle can determine a monitoring time and an attentiveness window. Upon detecting attentiveness of an operator for the duration of the attentiveness window, the monitoring time is increased by an adjustment increment and a counter is incremented. Upon detecting inattentiveness of the operator during the duration of the attentiveness window, the counter is incremented. Upon expiration of the monitoring time, a component in the vehicle is actuated based on the inattentiveness of the operator. The monitoring time can be initiated for a vehicle operator assistance feature such as hands-free operation.
