Abstract: A method for identifying a change of a range of a lidar sensor involves a lidar sensor receiving a reference noise level of infrared radiation. A signal-to-noise ratio of infrared radiation reflected on the reference target and received by the lidar sensor are identified in a reference measurement having a reference target located at a predetermined distance to the lidar sensor. In a driving operation measurement, a current noise level of received infrared radiation is identified and a theoretical distance to a position where the reference target ought to be if, at the current noise level, the same signal-to-noise ratio applies as in the reference measurement is identified from the current noise level. A change in range calculation identifies a difference between the predetermined distance and the theoretical distance. The difference corresponds to the change of the range of the lidar sensor compared to its range during the reference measurement.

Abstract: A method for validating a software status of a vehicle in a system involves testing the software in the vehicle in the system. The system controls the vehicle according to input data and subsequently records output data of the vehicle. In an inactive state of the system, an in each case non-productive, old and new software status are compared in parallel, and by activating the system to an active state, a change to the productive software status takes place.

Abstract: A method for detecting dirt in the signal path of an optical sensor arrangement. To detect objects via a plurality of photodetector elements of the sensor arrangement, light signals are reflected at the objects to be detected. A respective object is classified according to its type and the object is assigned to an object class with a specified reflectivity during the classification. A distance to the object is measured. Crosstalk of the detected light signals on a plurality of photodetector elements is determined and a degree of dirtying is ascertained on the basis of the specified reflectivity ascertained during the classification, the distance and a degree of the crosstalk.

Abstract: A method and device for identifying contamination on a protective screen of a lidar sensor may involve determining a sector background noise in a particular sector of a detection region of the lidar sensor and a detection region background noise is determined in a remaining detection region or the entire detection region. Contamination in the sector in question is then determined if the sector background noise is significantly lower than the detection region background noise. Alternatively, or additionally, a sector background noise is determined in the sector in question at different sensitivities of a receiver of the lidar sensor, and contamination in the sector in question is then determined if a sector background noise determined with a higher sensitivity is not significantly higher than a sector background noise determined with a lower sensitivity.

Abstract: Calibrating a camera and/or a lidar sensor of a vehicle or a robot involves a camera capturing images of a vehicle or robot environment. The lidar sensor emits a real pattern into the vehicle or robot environment in at least one portion of a detection range of the camera, and the real pattern is captured by the camera. A virtual pattern generated in a coordinate system of the lidar sensor is projected onto a virtual plane in the vehicle or robot environment by the lidar sensor. Laser radiation emitted by the lidar sensor penetrates the virtual plane and the real pattern correlating with the virtual pattern is generated on a real projection surface. The real pattern captured by the camera is recalculated onto the virtual plane based on a surface profile of the real projection surface. A rectified virtual pattern is generated in a coordinate system of the camera and the camera and/or lidar sensor is/are calibrated by comparing the virtual pattern and the rectified virtual pattern.

Abstract: A method for calibrating a lidar sensor of a vehicle or of a robot may include applying laser radiation of the lidar sensor to a reference object in a reference calibration process. The lidar sensor generates a sensor signal, which correlates to the laser radiation and has a reference intensity, and a sensitivity of the lidar receiver being calibrated according to the reference intensity. At least one camera is used to detect whether at least one object having reflectivity corresponding to that of a reference object of the reference calibration process is present in the detection range of the lidar sensor. An intensity of a sensor signal generated on the basis of laser radiation reflected by the object is determined, the determined intensity being compared with an associated reference intensity and the sensitivity of the lidar receiver being calibrated according to the comparison of the intensity with the reference intensity.

Abstract: A method and a device for detecting the opening state of a garage door or the like, such as a door that restricts entry by a vehicle are provided. A control apparatus generates a predetermined light pattern. A headlight apparatus projects the predetermined light pattern onto the door, while a camera apparatus detects the light pattern projected onto the door. The control apparatus compares the light pattern detected by the camera apparatus with the predetermined light pattern and outputs information signals according to the differences between the detected light pattern and the predetermined light pattern. The differences determine the opening state of the door.
