    摘要： The head pose of a motor vehicle driver with respect to a vehicle frame of reference is assessed with a relative motion sensor positioned rearward of the driver's head, such as in or on the headrest of the driver's seat. The relative motion sensor detects changes in the position of the driver's head, and the detected changes are used to determine the driver's head pose, and specifically, whether the head pose is forward-looking (i.e., with the driver paying attention to the forward field-of-view) or non-forward-looking. The determined head pose is assumed to be initially forward-looking, and is thereafter biased toward forward-looking whenever driver behavior characteristic of a forward-looking head pose is recognized.

    摘要： An awareness detection system and method that includes an imaging device positioned to obtain a plurality of images of at least a portion of a subject's head, and an awareness processor in communication with the imaging device, wherein the awareness processor receives the plurality of images from the imaging device. The awareness processor performs the steps including classifying at least one image of the plurality of images based upon at least a portion of the subject's head, monitoring movement of at least one eye of the subject if the at least one image is classified as a predetermined classification, and determining an awareness state of the subject based upon the monitored movement of the at least one eye.

    摘要： A system and a method for determining whether an operator of a vehicle has an impaired cognitive state are provided. The method includes determining an intoxication indication value indicative of whether the operator is intoxicated, utilizing a controller. The method further includes determining a drowsiness indication value indicative of whether the operator is drowsy, utilizing the controller. The method further includes determining a fatigue indication value indicative of whether the operator is fatigued, utilizing the controller. The method further includes determining a cognitively impaired indication value based on at least one of the intoxication indication value, the drowsiness indication value, and the fatigue indication value. The method further includes generating a signal indicating that the operator is cognitively impaired when the cognitively impaired indication value is greater than a threshold cognitively impaired indication value, utilizing the controller.
