Abstract: Devices, systems, and methods are provided for enhanced sensor cleaning validation. A device may determine a baseline performance measurement associated with a clean performance baseline of a sensor. The device may actuate a cleaning mechanism to remove at least a portion of an obstruction deposited on the sensor. The device may determine a first post-clean performance measurement associated with the sensor. The device may determine a degradation measurement between the baseline performance measurement and the first post-clean performance measurement, wherein the degradation measurement indicates an effectiveness of the cleaning mechanism.

Abstract: A sensor degradation detection and remediation system includes one or more sensors configured to collect image data from an environment. A combination of techniques may be used to detect degradations within regions of the image data captured by a sensor, including one or more of determining a level of the visual consistency between the associated image regions captured by different sensors, determining a level of opaqueness of the image regions, and/or measuring temporal movement of the image regions captured by a sensor over a period of time. Operations of a vehicle or other system may be controlled based at least in part on the detection of degradations of the image data captured by the sensors, including automated cleaning of a sensor surface, reducing a level of reliance on the image data received from the sensor, and/or changing a direction of travel of the vehicle.

Abstract: Techniques for determining a degraded state associated with a sensor are discussed herein. For example, a sensor associated with vehicle may captured data of an environment. A portion of the data may represent a portion of the vehicle. Data associated with a region of interest can be determined based on a calibration associated with the sensor. For example, in the context of image data, image coordinates may be used to determine a region of interest, while in the context of lidar data, a beam and/or azimuth can be used to determine a region of interest. A data metric can be determined for data in the region of interest, and an action can be determined based on the data metric. For example, the action can include cleaning a sensor, scheduling maintenance, reducing a confidence associated with the data, or slowing or stopping the vehicle.

Abstract: The present invention refers to a method for safe at least semi-autonomous driving operation of an ego vehicle (1) in case of sun glare (2), comprising the following steps: checking, by a computing system, whether one or more vehicle sensors of the ego vehicle (1) are dazzled by sun glare (2) (10); if yes (T), detecting environmental information by a detection system of the ego vehicle (1) (20); checking, by a computing system, the environmental information for a presence of at least one dynamic object (3), which is suitable for intercepting the sun glare (2) during driving operation of the ego vehicle (1) (30); if yes (T), checking, by a computing system, whether the ego vehicle (1) can execute a driving maneuver in such a way that the at least one dynamic object (3) intercepts the sun glare (2) during driving operation of the ego vehicle (1) (40); if yes (T), executing the driving maneuver (50). The present invention also refers to a driving support system comprising means for executing the steps of the method. Furthermore, the present invention refers to a vehicle comprising the driving support system. Furthermore, the present invention refers to a computer program comprising instructions which, when the program is executed by a computer, cause the computer to execute the steps of the method. Furthermore, the present invention refers to a data carrier signal and a computer-readable medium.

Abstract: Some embodiments of the invention include a method for updating an occlusion probability map. An occlusion probability map,ap represents the probability that a given portion of the sensor field is occluded from one or more sensors. In some embodiments, a method may include receiving field of view data from a sensor system; producing a probabilistic model of the sensor field of view; and updating an occlusion probability map using the probabilistic model and field of view data.
