  • Patent number: 7490944
    Abstract: An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly, a casing having a reflective element, a compass sensor and a control. The compass sensor is disposed within the mirror casing and has a first magnetoresponsive sensing element and a second magnetoresponsive sensing element. The control receives a first signal indicative of a magnetic field sensed by the first magnetoresponsive sensing element and a second signal indicative of a magnetic field sensed by the second magnetoresponsive sensing element. The control determines that the casing is adjusted by an occupant of the vehicle in response to a change in the first and second signals being indicative of an abrupt movement of the casing about the mounting structure by an occupant of the vehicle. The control is operable to enter a rapid compensating mode to compensate for the mirror adjustment.

  • Publication number: 20060139782
    Abstract: An interior rearview mirror system includes an interior rearview mirror assembly and a compass sensor having first and second magnetoresponsive sensing elements. A physical mount mounts the compass sensor at the rear of the reflective element whereby the compass sensor adjusts in tandem with adjustment of the reflective element by the driver of the vehicle. The physical mount is configured to at least partially offset the angle of the reflective element selected by the driver. A control receives a first signal indicative of a magnetic field sensed by the first magnetoresponsive sensing element and receives a second signal indicative of a magnetic field sensed by the second magnetoresponsive sensing element. The control determines a directional heading of the vehicle based on the first and second signals, and automatically compensates for a deviating magnetic field of the vehicle and generates a signal indicative of the directional heading of the vehicle.

  • Publication number: 20060132941
    Abstract: An automatic dimming vehicle mirror system includes an automatic dimming mirror assembly having automatic dimming circuitry. The automatic dimming circuitry includes a mirror control and at least a first silicon-based photo sensor and a second silicon-based photo sensor. The first silicon-based photo sensor is sensitive to both visible light and infrared light. The second silicon-based photo sensor is sensitive principally to infrared light. The mirror control distinguishes headlamp sources from non-headlamp sources by a ratio of a signal indicative of light detected by the first photo sensor to a signal indicative of light detected by the second photo sensor.

  • Publication number: 20050262714
    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.
