VEHICULAR DRIVER MONITORING SYSTEM

A vehicular driver monitoring system includes a camera disposed at an interior cabin of a vehicle and that views at least a head region of a driver of the vehicle. The system, based on processing of image data captured by the camera, determines a current behavior of the driver. The system determines a threshold level of distraction associated with the current behavior based on a current operating condition of the vehicle. The system, while the driver is operating the vehicle and based on the determined current behavior and the determined threshold level of distraction, determines that the driver is distracted. Responsive to determination that the driver is distracted, an alert is generated.
