    摘要： An optical monitoring system serves to monitor surroundings, having a monitoring apparatus, the visual or scanning field of which is captured by a lens, and a protection panel (112) which protects the lens from precipitation and covers at least the visual or scanning field of the monitoring apparatus. In order to avoid the signal quality of the monitoring apparatus being impaired by precipitation on the protection panel, it is proposed that the protection panel (12; 112; 218; 318) is acoustically coupled to at least one ultrasonic transducer (10). The optical monitoring system can be included into the control system of a vehicle for autonomous driving, wherein, overall, it is possible to obtain increased safety of the control system.

    摘要： Techniques are described for cleaning sensors of a vehicle. An attribute of the surrounding environment (e.g., type of precipitation, intensity of precipitation, etc.) is determined along with orientations and/or attributes of the sensors (e.g. fields-of-view, focal lengths, spectral ranges, etc). Cleaning frequencies are then be determined based, at least in part, on the attribute of the environment together with the orientations and/or attributes of the sensors. Cleaning elements are then activated at the determined frequencies to clean the sensors. In some examples, the cleaning frequencies may be determined based additionally on an attribute of travel of the vehicle (e.g. direction of travel of the vehicle, speed of the vehicle, etc.).

    摘要： Provided is a sensor wiper for a sensor pin used for fluid level detection. The sensor wiper comprises at least one swinging wiper having a wiper head for rotational association with a sensor pin, and an arcuate arm connected at a head end thereof to the wiper head. A plurality of inwardly directed radial elements are associated with the wiper head for engagement with the sensor pin. Sloshing action of fluids act upon the arcuate arm to move the wiping head, thereby causing the radial elements to engage and wipe the sensor pin.
