A system for executing a high-reliability application and a third party application is provided. The system includes an application module and a second module. The application module has control logic for executing the high reliability application and the third party application. The high reliability application generates a message sequence. The application module includes a normal operating mode, a high reliability mode, and a high reliability boot. The second module is in communication with the application module, and includes a first control logic for monitoring the message sequence when the application module is operating in the normal operating mode. The second module also includes control logic for initiating the high reliability boot in the application module.

The laser of a laser-generated windshield display is controlled to initially deflect the laser beam in the direction of a reflective target disposed outside a display region of the windshield, and a sensor disposed in a reflection path of the target is sampled to detect the presence of a feedback signal that occurs when the laser beam impinges on the sensor. If the feedback signal is detected, the laser beam is deflected onto the display region to generate a driver display; but if the feedback signal is not detected, the laser is automatically turned-off. Once the laser is turned off for lack of a feedback signal, the control is repeated following a specified delay interval so that the driver display will automatically resume the when the condition that prevented generation of the feedback signal is cured.

A drive system for powering LED triads includes a controller for supplying power to one or more LED triad modules with integral encoding of the desired hue and intensity information. The LED triad modules each include an LED triad and decoding circuitry for activating the individual LED elements of the triad according to the encoded hue and intensity information. In the illustrated configuration, the controller supplies power to the LED triad modules over a pair of conductors, and the supplied power is modulated using a four-phase encoding sequence that is decoded by the decoding circuitry of each LED triad module so that each LED triad module produces light of the desired hue and intensity.

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.

Illumination and imaging system and method

Driver distraction in a motor vehicle is assessed by capacitively detecting the driver's head pose relative to the forward direction of vehicle motion. A symmetrical array of sensor electrodes is disposed in the cockpit ceiling above the driver's head, and pairs of electrodes disposed along varying axes of rotation with respect to the forward direction are successively activated for capacitance measurement. The capacitance measurements are combined to form a signal whose strength depends on the degree of alignment between the driver's head (i.e., the head pose) and the respective axes of rotation, and the driver's head pose is calculated to assess driver distraction.

A system and method are provided for actively illuminating and capturing images of an object, such as a driver of a vehicle to reduce glare. The system includes a video imaging camera orientated to generate images of the subject object (e.g., eye(s)) in successive video frames. The system also includes first and second light sources operable to illuminate the object one at a time. The system further includes a processor for processing the image by performing pixel-wise min operation to combine multiple frames into a single frame to reduce glare in the image. The system may remove glare caused by the illuminators and caused by external energy sources.

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.

An object awareness determination system and method of determining awareness of a driver of a vehicle to an object is provided. The system includes an object monitor including an object detection sensor for sensing an object in a field of view and determining a position of the object. The system also includes an eye gaze monitor including an imaging camera oriented to capture images of the vehicle driver including an eye of the driver. The gaze monitor determines an eye gaze vector. The system further has a controller for determining driver awareness of the object based on the detected object position and the eye gaze vector.

In a preferred embodiment, an apparatus for eye tracking, including: an illuminator; reflection apparatus to reflect illumination from the illuminator onto a surface of a windshield of a vehicle in which the windshield is installed, such that the illumination is reflected onto at least an eye of a person in the vehicle, and to reflect an image of the at least an eye, and a sensor to receive a reflection of the image of the at least an eye reflected by the reflection apparatus and to produce an output signal representative thereof.

Eye tracking/HUD system

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.

A head up display system having a diffusing image plane or diffuser. The light output of a relatively small image source is imaged on the diffuser by way of imaging optics. A mirror is used to image light from the diffuser onto a windshield and correct for distortion caused by the windshield. The diffuser is advantageously used when a large field-of-view is desired, or sun load characteristics need to be addressed. The diffuser may be flat or curved in order to optimize the system for different applications. The magnification of the mirror may be made relatively low, and the solar energy density that is made incident on the image source is reduced, providing for a low cost, high performance, color head up display system.
