  • Publication number: 20090096937
    Abstract: An inventive rearview assembly (10) for a vehicle may comprise a mirror element (30) and a display (100) including a light management subassembly (101b). The subassembly may comprise an LCD placed behind a transflective layer of the mirror element. Despite a low transmittance through the transflective layer, the inventive display is capable of generating a viewable display image having an intensity of at least 250 cd/m2 and up to 6000 cd/m2. The rearview assembly may further comprise a trainable transmitter (910) and a graphical user interface (920) that includes at least one user actuated switch (902, 904, 906). The graphical user interface generates instructions for operation of the trainable transmitter. The video display selectively displays video images captured by a camera and the instructions supplied from the graphical user interface.

  • Patent number: 7361875
    Abstract: Equipment on automotive vehicle is controlled by a system including at least one semiconductor light sensor having variable sensitivity to light. Each light sensor generates a light signal indicative of the intensity of light incident on the light sensor. Control logic varies the sensitivity of the light sensor and generates equipment control signals based on received light signals. Sensitivity of light sensors may be varied by changing the integration time for producing charge from light incident on light transducers, by selecting between light transducers of different sensitivity within the light sensor, by using a light transducer with a sensitivity that is a function of the amount of incident light, and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors, headlamps, and moisture removal means.

  • Patent number: 7111968
    Abstract: A vehicle system is disclosed that includes a vehicle lamp assembly including a plurality of LEDs that emit white light so as to function as an illuminator light. The lamp assembly also may include a plurality of LEDs that emit colored light to function as a signal light. The lamp assembly may include a camera. The lamp assembly may serve as a CHMSL or as a tail light. The system also includes a controller that rapidly pulses the LEDs at a rate that is imperceivable by the human eye. The pulsing intervals of the LEDs may be related to the readout intervals of the camera sensor array. In this manner, the LEDs may be pulsed on during camera readout to increase the illumination while the camera is capturing an image, or may be pulsed off during camera readout to prevent feedback glare from interfering with image capture by the camera.

  • Patent number: 6906467
    Abstract: A system for automatically controlling continuously variable headlamps on a controlled vehicle includes an imaging system capable of determining lateral and elevational locations of headlamps from oncoming vehicles and tail lamps from leading vehicles. The system also includes a control unit that can acquire an image from in front of the controlled vehicle. The image covers a glare area including points at which drivers of oncoming and leading vehicles would perceive the headlamps to cause excessive glare. The image is processed to determine if at least one oncoming or leading vehicle is within the glare area. If at least one vehicle is within the glare area, the headlamp illumination range is reduced. Otherwise, the illumination range is set to full illumination range.
