  • Patent number: 7777778
    Abstract: A system and method are provided for actively illuminating and monitoring a subject, such as a driver of a vehicle. The system includes a video imaging camera orientated to generate images of the subject eye(s). The system also includes first and second light sources offset from each other and operable to illuminate the subject. The system further includes a controller for controlling illumination of the first and second light sources such that when the imaging camera detects sufficient glare, the controller controls the first and second light sources to minimize the glare. This is achieved by turning off the illuminating source causing the glare.

  • Patent number: 7501938
    Abstract: A lane change assist system and method are provided for assisting the driver of the vehicle in maneuvering a lane change. The system includes a range sensor mounted on a vehicle for sensing range to an object in a side detection zone adjacent to one side of the vehicle. The system also includes a controller for determining when the side detection zone is clear for the vehicle to change lanes based on the sensed range signal. The controller determines whether there is sufficient space to initial a lane change maneuver based on the sensed range signal and generates an output signal indicative thereof. An output is provided to warning lights indicative of the determined state for initiating the lane change maneuver.

  • Patent number: 7432800
    Abstract: A warning display system visually warns the driver of a vehicle of an object in a detection zone, such as a blind spot region of the vehicle. The display system includes an imaging medium for displaying a warning indicator and a light source disposed behind the imaging medium for providing a controlled illumination of the warning indicator. An object detection sensor detects an object in a vehicle detection zone. One or more signals are processed to determine an anticipated movement of the vehicle in relation to the object. The system further includes a controller for adaptively controlling illumination of the light source to increase illumination of the warning indicator when the vehicle is anticipated to be moving towards the object.

  • Patent number: 7230523
    Abstract: A rear view mirror/video display includes a one-way mirror and a selectively activated video display that is mounted immediately behind the one-way mirror so that the driver is presented with a typical semi-obstructed rearward view when the video display is deactivated, and an unobstructed rearward view of substantially the same size and aspect ratio when the video display is activated. The video image is obtained from an imaging device mounted to capture a rearward field-of-view that is unobstructed by vehicle body panels but otherwise corresponds in content with that of the image reflected by the one-way mirror. Activation and deactivation of the video display may be manual, but is preferably automatic based on vehicle operating conditions.

  • Patent number: 7146276
    Abstract: 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.

  • Patent number: 6859144
    Abstract: 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.
