Abstract
A vehicular driver monitoring system includes an interior camera viewing at least a head region of a driver of a vehicle. Driver information pertaining to the driver of the vehicle is provided to an electronic control unit (ECU). Based at least in part on (i) processing at the ECU of image data captured by the interior camera and/or (ii) the received driver information, the vehicular driver monitoring system estimates a distraction workload of the driver and a driving workload of the driver. At least in part responsive to processing at the ECU of the estimated distraction workload and the estimated driving workload, the vehicular driver monitoring system determines an amount of driver attention. The amount of driver attention is determined at least in part by weighting the driving workload and the distraction workload based at least in part on driving conditions.
