    摘要: A sensor system is described for detecting wetting of a window includes a photodetector having multiple light-sensitive elements and a light source for emitting light to a detection region of the window in such a way that a portion of the light is reflected at the window, and another portion of the light passes through the window. The light source and the light-sensitive element are situated in such a way that a portion of the light from the light source which passes through the window is reflected at the wetting and strikes a portion of the light-sensitive elements. The light source includes a lighting element which is set up to irradiate into a transparent body. The transparent body has a surface which has defined unevennesses for the diffuse radiation of the irradiated light.

    摘要: An arrangement for operating a wiper includes a sensor for detecting a wetting state of a pane and outputting a sensor signal based thereon, an evaluator for receiving the sensor signal from the sensor, and evaluating the sensor signal, and an actuator for actuating the wiper, the actuator being actuated by the evaluator to produce one of a plurality of wiping modes, including a stage II wiping mode for heavy wetting conditions. The evaluator includes an evaluation stage for determining whether a degree of wetting corresponding to a stage II wiping condition occurs after a prolonged wiping break, for example after passing through a tunnel, and a processing stage. If a degree of wetting corresponding to a stage II wiping condition is determined to occur after a prolonged wiping break, the processing stage is actuated by the evaluation stage to cause a change-over to stage II wiping within a shorter time period than in a case where a prolonged wiping break is not present for a comparable degree of wetting.

    摘要: The invention concerns a method and an arrangement for monitoring a computing unit, such as is used, for example, in control devices. The monitoring device generates a reset signal if the supply voltage drops below a voltage level, below which a defined operation is not ensured. Following the occurrence of a reset signal, a fixedly predetermined code is compared with the content of a volatile memory unit and a signal is emitted based on the comparison result, which determines the further process sequence. A fast and secure determination of the continued optimum process sequence is obtained by continuing with the control of the operating state as it exists at the time when the reset signal occurs, provided the content of the volatile memory unit coincides with the code, whereas a new initialization is carried out if the content of the volatile memory unit deviates from the code.

    摘要: An apparatus for operating a windshield wiper having a sensor device for determining the state of wetness of a windshield, an evaluation device which receives the sensor signal, a dirt-recognition stage and an adjusting device for updating a reference value when dirt is present on the windshield, and an actuating unit for the windshield wiper which can be actuated by the evaluation device in order to initiate a wiping process if the difference between the reference value and a current measured value of the sensor signal exceeds a predetermined threshold value. The measured values can be evaluated by the dirt-recognition stage with respect to signal breaks of the sensor signal caused by the wiping action of the wiper across the sensor surface.

Even when individual drops impact the windshield, appropriate wiping operation can be initiated during a drying phase of the windshield, because it is provided that current measured values of the sensor signal can be supplied to both the difference-initiating stage and a drop-recognition device that is provided in the evaluation device and in which the sensor signal can be evaluated with respect to individual drops using signal breaks, and that an adapted control signal can be generated by the control-signal-generating stage when a minimum signal break is detected, with which signal corresponding wiping operation can be initiated by way of the actuating unit.

    摘要: A arrangement for operating a windshield wiper in a direct mode, an intermittent mode or a continuous mode, having a sensor device for detecting a degree of moisture on the windshield, an evaluation device for the sensor signal and an actuation unit for the windshield wiper. A non-disturbing smoothing of the interval times is accomplished in a simple manner in that an interval time control has a smoothing stage for the interval time with which it can be determined during which time segment of predetermined time segments within the interval time a wetting event occurs, starting from the beginning of the interval, and with which the second interval time can be shortened all the more, the earlier the time segment appears during which the wetting event occurs.

    摘要: The invention relates to an arrangement for the automatic operation of a windshield wiper, having a sensor device for detecting the degree of moisture on a windshield, an evaluation device, and an actuation unit for the windshield wiper which is actuated by the evaluation device. The degree of moisture on the windshield can be analyzed better in that the evaluation device in has a recognition stage for recognizing drying moisture that is present on the windshield. By means of this recognition stage, whether the level of the measured values is rising as a result of the drying process can be determined from a time sequence of measured values derived from the sensor signal. In this manner, unnecessary wiping actions can be prevented.

    摘要: A device for operating a windshield wiper with an automatic wiper control. A fast reaction to a suddenly occurring heavy wetting event is assured without adversely affecting the sequence of intermittent wiper operation. This is achieved by an evaluation unit which has a surge detection stage that makes it possible to detect, during intermittent operation when a sensor signal falls short of a surge threshold and by triggering a control signal for at least one wiping action when the signal falls short of the surge threshold.
