Abstract: A method for detecting objects in the surroundings of a vehicle includes receiving sensor data which describe the objects in the surroundings from a surroundings sensor of the vehicle; determining each of the corners of the objects, with the corners describing outer delimitations of each object; determining a relative position of each of the corners to the surroundings sensor; sorting the determined corners in a predetermined angle direction; checking, for each of the corners in the angle direction, whether the corners are covered by another of the objects, on the basis of the relative position of each of the corners to the surroundings sensor; and determining regions of each of the objects that can be detected by the surroundings sensor, on the basis of checking the corners.

Abstract: A concept of characterizing an object based on measurement samples from one or more location sensors, the measurement samples having a first spatial resolution. The measurement samples are quantized to a grid map of weighted cells having a second spatial resolution lower than the first spatial resolution, wherein a measurement sample contributes to a weight coefficient of one or more weighted cells depending on a measurement accuracy. Parameters of one or more lines fitting the weighted cells are computed to obtain a characterization of the object.

Abstract: A method for recognizing road users in an environment of a vehicle includes determining detections that describe potential objects in the environment, identifying faulty detections within the detections, and recognizing the road users on the basis of the detections other than the faulty detections. Identifying the faulty detections further includes, for each detection, checking, on the basis of the spatial position with respect to other detections, whether the detection originates from a reflection effect of a plurality of predefined reflection effects of the radar signal, wherein the plurality of predefined reflection effects describes at least one additional reflection of the radar signal after a first reflection of the radar signal by an object.

Abstract: Camera data and radar echoes are received from the surroundings. At least one radar echo is assigned to a delimiting frame of an object detected on the basis of a camera, the delimiting frame being generated using the camera data by comparing corresponding azimuth angles and specified distances of the radar echo and the object detected on the basis of a camera. In the event of a successful assignment, a distance which is assumed on the basis of a camera is corrected according to the distance of the respective detected object in the surroundings, said distance being determined in a radar-based manner. The respective delimiting frame together with the corrected distance is then output as an object data set which indicates a successful object detection.

Abstract: A method (700) for determining the value of a size of an object (150) is described. The method (710) comprises determining (711) an occupancy grid (200) indicating evidence that individual cells (201) are vacant or occupied by the object (150). Further, the method (710) comprises determining (712) a subset of cells (201) associated with the object (150). Further, the method (710) comprises detecting (713) two opposing bounding edges of the object (150), and determining (714) a measurement value of the size of the object (150) based on the distance between the detected edges of the object (150). The method (710) further comprises determining (715) a quality measure indicating how well the two opposing edges of the object (150) could be detected, and determining (716) a measurement probability distribution of the size of the object (150) dependent on the quality measure.

Abstract: A vehicle environment detection system (2) including a control unit (4) and a sensor arrangement (3) that in turn includes at least two sensor arrangement parts (3a, 3b). The control unit (4) is arranged to determine one or more systematic errors in a certain direction (9, 10) for one sensor arrangement part (3a, 3b) by combining acquired sensor data for the sensor arrangement part (3a, 3b) with acquired sensor data from another sensor arrangement part (3b, 3a). The another sensor arrangement part (3b, 3a) has a lower degree of systematic error in the certain direction (9, 10) than the sensor arrangement part (3a, 3b).
