摘要： A precipitation sensor (32) for detecting when a predetermined fraction of the sensor area is covered with water drops comprises an insulating substrate (20), a pair of spaced electrodes (34,34′) of conductive material on the substrate (20), and an array of conductive spots (36) on the substrate (20) between the electrodes (34,34′), the spots (36) being arranged in a two-dimensional pattern to define a plurality of open circuit paths between the electrodes (34,34′) when the substrate (20) is dry and at least one closed circuit when at least some of the spots (36) are bridged by water drops. This sensor uses the physical principle of percolation to respond accurately to small amounts of precipitation and is preferably integrated in the wipe area (24) of a windshield surface (20) of a motor vehicle, and is incorporated in a wiper control system (26,28,30) thereof.

摘要： In an automotive windshield wiper control system, a rain sensor provides a rain condition-indicative signal useful in controlling the wiper in its intermittent operation mode. That signal is integrated to yield a value representing rain accumulation on the windshield, and when the integrated value exceeds a given threshold, the wiper is reciprocated once to clear the windshield. In order to prevent a rhythmic wiper operation, the signal integrator is disabled during wiper operation so that the integrated value will not approach the threshold too soon after or even before the end of the preceding wiper operation cycle.

摘要： A system for detecting the presence of rain droplets on a windshield employs a source of radiant energy, such as an LED (70), and a photodetector installed on the instrument panel of a vehicle. The LED (70) and the photodiode (85) are arranged with respect to one another such that light from the LED (70) cannot reflect directly off the windshield (81) onto the photodiode (85). Only when the light from the LED is back scattered by an environmental condition, such as the raindrops on the exterior (82) of the windshield, the condensation of moisture on the interior (80) of the windshield, or the presence of smoke in the cabin, will the photodiode receive the light from the LED. Each of these environmental conditions has a predeterminable characteristic signature that permits the processing of data to detect same. An ambient light signal is subtracted from the combination of the rain and ambient light signals by pulsed operation of the LED and subtracting the ambient light signal, which is detected when the LED is dark, from the combined LED and ambient light signal which is present when the LED is illuminated. A further LED (100) is provided to effect a fog detection system that detects condensation on the interior of the vehicle windshield. The further LED (100) illuminates the photodiode in a manner whereby the light on the photodiode is reduced when condensation is present. Also, a monitoring arrangement that employs a separate light sensor provides compensation for variances resulting from component aging and thermal influences.

摘要： The invention relates to a device for the automatic control of a windscreen wiper motor. Said device has a moisture sensor which emits a signal depending on the moisture on the windscreen or another point on a motor vehicle so that this signal to some extent produces an analog reflection of the moisture varying in time. The output signal of the sensor is evaluated in such a way that it is continuously compared with a threshold value which can be altered. Every time this threshold value is reached or exceeded by a pulse-like change in the sensor output signal, this event is counted. After a given number Z of such events the windscreen wiper motor is switched on.

摘要： A system for detecting the presence of rain droplets on a windshield (17) employs a source of light, such as an LED (11), and a photodetector (12) installed on the dashboard (13) of a vehicle. The LED (11) and the photodiode (12) are arranged with respect to one another such that light from the LED (11) cannot reflect directly off the windshield into the photodiode (12). Only when the light from the LED is backscattered by an environmental condition, such as the raindrops (25) on the exterior of the windshield (17), the condensation of moisture on the interior of the windshield (17), or the presence of smoke in the cabin, will the photodiode (12) receive the light from the LED (11). Each of these environmental conditions has a predeterminable characteristic signature which permits the processing of data to detect same. An ambient light signal is subtracted from the combination of the rain and ambient light signals by pulsed operation of the LED (11) and subtracting the ambient light signal, which is detected when the LED (11) is dark, from the combined LED (11) and ambient light signal which is present when the LED (11) is illuminated.
