Abstract: A method for self-balancing of a lambda sensor (18, 20, 26) is provided. The method measures pumping current (Ip) and pumping voltage (Up) of the lambda sensor (18, 20, 26), and checks whether the measured pumping current (Ip) and the measured pumping voltage (Up) lie within a specified tolerance range (33). If values lie outside the tolerance range (33) of the characteristic curve specification, an adjustment of the lambda value (?) occurs with the aid of the pumping voltage (Up) of the lambda sensor (18, 20, 26), and, in a substantially adjusted state, a further pumping current (Ip) of the lambda sensor (18, 20, 26) is measured and the pumping current offset (32) is derived from the further pumping current (Up). Thus, precise self-balancing of the lambda sensor (18, 20, 26) is carried out, thereby enabling a good exhaust gas after-treatment.

Abstract: A method is provided for producing a winding (1) for an electric machine (10).

Thus, an insulating structure (15) is provided after cooling the distributed material of the material reservoir (5). The insulating structure (15) insulates the conductor ends (3) against their surroundings at least at the bonding point (4).

Abstract: A method for labeling vehicle-generated sensor data uses radar points from a radar detector, image data from camera(s) and lidar data from a lidar with overlapping fields-of-view. The method assigns plausibility labels to the radar points from the image data corrected by image-rectification, generates a camera-based depth estimation from a neural network calibrated by the lidar data, calculating a three-dimensional point from two-dimensional image information by the camera-based depth estimation, with the cloud being associated with the radar points and the lidar data being associated with the radar points. A radar/lidar plausibility and a radar/camera plausibility arise and are merged to form an optics-based plausibility. A radar/tracking plausibility is assigned to each radar point by tracking.
