摘要： 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.

摘要： Equipment on automotive vehicle (20) is controlled by a system at least one semiconductor light sensor (170, 170′) having variable sensitivity to light. Each light sensor generates a light signal (164) indicative of the intensity of light incident on the light sensor. Control logic (66) varies the sensitivity of the light sensor and generates equipment control signals (166) based on received light signals. Sensitivity of light sensors (170, 170′) may be varied by changing the integration time (228) for producing charge from light (176) incident on light transducers (178), by selecting between light transducers (178, 490, 500, 504) of different sensitivity within the light sensor (170), by using a light transducer (530) with a sensitivity that is a function of the amount of incident light (176), and the like. Controlled equipment includes devices such as automatically dimming rearview mirrors (24,26), headlamps (44), and moisture removal means (38, 40, 42).

摘要： An automatically dimming mirror includes a dimming element having variable reflectivity, the degree of reflectivity based on a control signal. An ambient light sensor is positioned to receive light from a region generally in front of the vehicle. The ambient light sensor outputs a discrete ambient light signal based on the amount of light incident on the ambient light sensor over an integration period. A glare sensor is positioned to view the scene generally behind the vehicle operator. The glare sensor outputs a discrete glare signal based on the amount of light incident on the glare sensor over an integration period. A dimming logic determines an ambient light level based on the ambient light signal. The glare integration period is determined based on the ambient light level. The glare signal resulting from the glare integration period determines a mirror glare level used to set the dimming element control signal.

摘要： Automatically dimming rearview mirrors allow a vehicle operator to view a scene generally behind the operator at a reflectivity level automatically adjusted to ambient light and glare levels. An automatically dimming mirror includes a dimming element having a variably reflective surface, the degree of reflectivity based on a control signal. An ambient light sensor is positioned to receive light from a region generally in front of the vehicle. The ambient light sensor outputs a discrete ambient light signal based on the amount of light incident on the ambient light sensor over an integration period. A glare sensor is positioned to view the scene generally behind the vehicle operator. The glare sensor outputs a discrete glare signal based on the amount of light incident on the glare sensor over an integration period. A dimming logic determines an ambient light level based on the ambient light signal. The glare integration period is determined based on the ambient light level. The glare signal resulting from the glare integration period determines a mirror glare level used to set the dimming element control signal. The use of variable integration times increases the dynamic range of the light sensors, improving the mirror dimming response.

摘要： Moisture detection permits moisture removal equipment, such as automotive windshield wipers and defogger systems, to be operated automatically. A system for detecting moisture on a surface includes a light emitter directed at the surface. The presence of moisture is based on the intensity of light from the emitter reflected by the surface and received by a light sensor. The light sensor accumulates charge in response to incident light over a variable integration period.

摘要： Light sensors having a wide dynamic range are used in a variety of applications. A wide dynamic range light sensor includes an exposed photodiode light transducer accumulating charge in proportion to light incident over an integration period. Sensor logic determines a light integration period prior to the beginning of integration and the charge is reset. Charge accumulated by the exposed light transducer over the light integration period is measured and a pulse having a width based on the accumulated charge is determined.
