  • Patent number: 7643200
    Abstract: An exterior reflective mirror element suitable for a vehicle includes a transparent glass substrate having a reflector and a visual indicator display disposed to the rear of the substrate. The visual indicator display may be part of a blind spot detection and display system of the vehicle wherein the visual indicator display is actuated to emit light responsive to a detection by a blind spot detection detector of the equipped vehicle of an overtaking vehicle in a side lane adjacent the side of the equipped vehicle. The visual indicator display includes at least a first indicator at a first location to the rear of the exterior reflective mirror element. A first portion of the reflector may be at least partially removed at the first location in order to establish an at least partially transmissive first portion of the exterior reflective mirror element at the first location.

  • Patent number: 7600878
    Abstract: An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly, a mirror casing, a reflective element, an information display, a compass sensor and control circuitry. The compass sensor is disposed in the mirror casing and has at least a first magnetoresponsive sensing element and a second magnetoresponsive sensing element. The information display is disposed behind the reflective element whereby information displayed by the information display is viewable through the transflective reflector by a driver of a vehicle when the information display is displaying information. The control circuitry determines a directional heading of the vehicle responsive to the sensing by the first and second magnetoresponsive sensing elements, and the control circuitry automatically compensates for a deviating magnetic field of the vehicle and generates a signal indicative of the directional heading of the vehicle. The information display displays the directional heading of the vehicle.

  • Patent number: 7586666
    Abstract: An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly including a reflective element having a transparent glass substrate with a transflective reflector established at a surface thereof. The transflective reflector includes at least three thin film layers, which include at least one metallic layer. The transflective reflector exhibits a substantially spectrally neutral reflectant characteristic as viewed by a driver operating a vehicle equipped with the mirror assembly. A backlit active matrix liquid crystal video display screen is disposed behind the transflective reflector. Display information passes through the glass substrate and the transflective reflector for viewing by a driver operating the equipped vehicle. At least one silicon photo sensor is configured to detect ambient light at the vehicle, and the display intensity is adjustable responsive to a sensing of ambient light by the least one silicon photo sensor.

  • Patent number: 7581859
    Abstract: An exterior mirror sub-assembly includes a reflective element, a back plate, and a display element having a light source that is activatable to emit light. The display element attaches to a display receiving portion of the back plate and the light source is activatable to emit light through the display receiving portion. The display receiving portion may be configured to orient the display element at a predetermined angle so that light exiting the display element when the light source is activated may be directed (a) generally away from the vehicle when the mirror assembly is mounted to the vehicle so as to be principally viewed by drivers of other vehicles or (b) generally toward the driver of the vehicle when the mirror assembly is mounted to the vehicle so as to be principally viewed by the driver of the host vehicle.

  • Patent number: 7541570
    Abstract: A vehicle rearview mirror system includes a variable reflectance reflective element, an ambient light sensor that is operable to sense ambient light, and a glare light sensor that is operable to sense glare light. A control circuit is responsive to light detection by at least one of the ambient and glare light sensors and establishes a reflectance level of the reflective element. A video display screen is disposed behind the reflective element operable to display video information through the reflective element and viewable through the mirror reflector of the reflective element by a driver of the vehicle when the video display screen is activated, and substantially non-viewable by the driver of the vehicle when the video display screen is not activated.

  • Patent number: 7538316
    Abstract: An accessory mounting system suitable for use in a vehicle includes an assembly adapted for releasable mounting to a receiving structure on the interior surface at a portion of the windshield of the vehicle. A light absorbing layer is at that portion of the windshield and at least partially hides the assembly from view by a viewer external the vehicle who is viewing through the windshield when the assembly is normally mounted to the receiving structure. The light absorbing layer includes a light transmitting portion. At least two accessories are housed by the assembly and one of the two accessories includes a forwardly-viewing camera that views through the light transmitting portion of the light absorbing layer at that portion of the windshield of the vehicle when the assembly is mounted to the receiving structure, and wherein the light absorbing layer comprises a ceramic frit layer.

  • Patent number: 7331115
    Abstract: A compass compensation system is provided for automatically and continuously calibrating an electronic compass for a vehicle, without requiring an initial manual calibration or preset of the vehicle magnetic signature. The system initially adjusts a two axis sensor of the compass in response to a sampling of at least one initial data point. The system further calibrates the compass by sampling data points that are substantially opposite to one another on a plot of a magnetic field and averaging an ordinate of the data points to determine a respective zero value for the Earth magnetic field. The system also identifies a change in magnetic signature and adjusts the sensor assembly.

  • Patent number: 7205904
    Abstract: A vehicle lane change aid system includes a detector that is operative to detect the presence of an other vehicle adjacent the vehicle, an indicator for providing an indication that a lane change maneuver of the vehicle may affect the other vehicle and a control receiving movement information of the vehicle. The control develops a position history of the vehicle at least as a function of the movement information. The control compares the detected presence of the other vehicle with the position history and provides an indication when a lane change maneuver may affect the other vehicle.

  • Patent number: 6762676
    Abstract: A system is provided for detecting the presence of a human in a compartment of a vehicle that comprises a pyroelectric sensor and a control coupled to the pyroelectric sensor. The pyroelectric sensor comprises a first sensing element and a second sensing element. The first sensing element is arranged in an opposed electrical connection with respect to the second sensing element whereby infrared radiation from a human moving within the compartment is selectively detected by one of the first sensing element and the second sensing element, thereby producing an output signal of the pyroelectric sensor. This output signal is received by the control, and the control generates a control signal indicative of detection of a human within the compartment.
