摘要： A vehicular electrochromic rearview mirror system includes an interior electrochromic rearview mirror assembly and at least one exterior electrochromic rearview mirror assembly. Each mirror assembly includes an electrochromic reflective element that assumes a partial reflectance level in response to a signal applied thereto. A drive circuit applies a drive signal to each of the electrochromic reflective elements. The drive circuit may include a digital controller, a master drive circuit responsive to the digital controller to apply a first drive signal to one of the electrochromic reflective elements and a slave drive circuit responsive to the digital controller to apply a second drive signal to a second of the electrochromic reflective elements. The second drive signal may be derived from the first drive signal. The drive circuit may include a digital controller and a switching power supply controlled by the digital controller to produce a drive signal.

摘要： A calibration method for calibrating a compass system suitable for use in a vehicle includes sampling data points of a magnetic field with a magneto-responsive sensor and processing output signals of the sensor via compass circuitry. The compass circuitry includes an analog-to-digital converter for converting analog signals of the sensor to digital signals and a digital-to-analog converter for converting digital signals to analog signals that are supplied to the sensor for adjusting the sensor. The output signals of the sensor are adjusted to be within an operable range of an analog-to-digital converter via an initial calibration mode. After completion of the initial calibration mode, output signals of the sensor are processed to determine when the output signals are outside a range of the analog-to-digital converter. An output of a digital-to-analog converter is adjusted to reposition the output signals of the sensor to be within the range of the analog-to-digital converter.

摘要： 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.

摘要： A vehicular electrochromic rearview mirror system is provided including an interior electrochromic rearview mirror assembly and at least one exterior electrochromic rearview mirror assembly. The interior rearview mirror assembly has an interior electrochromic reflective element that assumes a partial reflectance level in response to a first drive signal applied thereto. The exterior rearview mirror assembly has an exterior electrochromic reflective element that assumes a partial reflectance level in response to a second drive signal applied thereto. A drive circuit is provided that supplies a first drive signal to the interior electrochromic reflective element and a second drive signal to the exterior electrochromic reflective element. The drive circuit variably controls a relationship between the partial reflectance levels of the interior reflective element and the exterior electrochromic reflective element by a control signal. The interior electrochromic reflective element has a partial reflectance level that is greater than or equal to the partial reflectance level of the exterior electrochromic reflective element.
