摘要： A system and method of assessing the driving task demand on the driver of a vehicle, and further controlling one or more devices on the vehicle as a function of the assessed driver demand is provided. The method includes sensing a coverage zone in relation to a vehicle, determining a presence of one or more objects in the sensed zone, measuring speed of each detected object in the sensed zone, determining a variation in speed of one or more sensed objects, and determining a driving task demand signal indicative of driving task demand of the vehicle as a function of the measured speed variability. The method controls one or more devices on the vehicle based on the driving task demand signal. Alternately, the driving task demand signal is determined based on vehicle speed.

摘要： A low-cost system for detecting a drowsy condition of a driver of a vehicle includes a video imaging camera located in the vehicle and oriented to generate images of a driver of the vehicle. The system also includes a processor for processing the images acquired by the video imaging camera. The processor monitors an eye and determines whether the eye is in an open position or a closed state. The processor further determines a time proportion of eye closure as the proportion of a time interval that the eye is in the closed position, and determines a driver drowsiness condition when the time proportion of eye closure exceeds a threshold value.

摘要： A system responds to detection of a vehicle situation by comparing a sensed eye gaze direction of the vehicle operator with data stored in memory. The stored data defines a first predetermined vehicle operator eye gaze direction indicating a high probability of operator desire that an alert signal be given and a second predetermined vehicle operator eye gaze direction indicating a low probability of operator desire that an alert signal be given. On the basis of the comparison, a first or second alert action is selected and an alert apparatus controlled accordingly. For example, the alternative alert actions may include (1) generating an alert signal versus not generating the alert signal, (2) generating an alert signal in a first manner versus generating an alert signal in a second manner, or (3) selecting a first value versus selecting a second value for a parameter in a mathematical control algorithm to determine when or whether to generate an alert signal.

摘要： A light warning system and method are provided for warning a driver of a vehicle of a sensed condition. The warning system includes a lighting device having first and second colored LEDs for generating a light beam viewable on a windshield in front of the driver of the vehicle. The system also includes a detection device for detecting a condition desirable of a warning and generating a warning signal. The system further includes a controller processing the warning signal and determining whether to present a light beam warning displayed to the driver on the windshield. The controller controls the lighting device to generate a flashing light beam, wherein the light beam flashes on and off for a time period less than one-half second.

摘要： A technique for combining a back-up aid function with a park assist function in a motor vehicle initially includes determining a distance from a motor vehicle to an object. Next, a velocity of the motor vehicle is determined. Then, a scaled version of the velocity and a minimum distance threshold are subtracted from the distance to provide a first multiplicand. Finally, a driver stimulus is provided as a function of the first multiplicand.

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： A relative motion sensor mounted in the headrest of a vehicle driver seat is used to assess the head pose of a vehicle driver and adjust the headrest position to optimize both the safety of the driver and the sensitivity of the relative motion sensor. At the beginning of each ignition cycle, the relative motion sensor is used to adjust the position of the headrest relative to the driver's head for optimal driver safety, and the relative motion sensor is oriented to provide optimal sensitivity for head pose assessment when the headrest is positioned for driver safety.
