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:
A rearview mirror assembly is disclosed for use in a vehicle that includes a mirror housing, a mounting structure for pivotally mounting the mirror housing to the vehicle such that the mirror housing may be both vertically and horizontally tilted, a compass sensor disposed in the mirror housing and coupled to a compass processing circuit, and a tilt detector for detecting when the mirror housing has been tilted from a prior position and for generating and transmitting a tilt detection signal to the compass processing circuit. The compass processing circuit may then respond to the reception of the tilt detecting signal by compensating the compass reading and/or display or by recalibrating the compass. The compass may be recalibrated using a variety of techniques, which may include, for example, comparing the sensor output values immediately prior and immediately after a tilt detection signal has been received and adjusting the calibration point by an amount corresponding to any difference between the sensor output levels.
