Abstract: A motor vehicle, in particular an at least partly electrically driven motor vehicle, has a battery device with at least one battery cell. The battery device is arranged in a floor region of the motor vehicle and has a protective device for protecting the battery device from mechanical action. The protective device has a protective plate, which is arranged in such a way that it covers the battery device at least in some regions, so that any mechanical actions are absorbed by the protective plate. The protective device also has an acoustic monitoring device, which monitors the protective plate acoustically and with which a signal can be output when a noise characteristic of a mechanical impairment of the protective plate is registered. Also disclosed is a method for monitoring the protective device.

An absorption body (24) is provided in the outer vessel (20) between the retention vessel (16) and the outer vessel (20) in the direction of gravity for absorbing moisture, and a moisture sensor detects moisture of the absorption body (24).

Abstract: A cargo floor, in particular a trunk or storage floor, for a motor vehicle. The cargo floor includes a layer-shaped construction with a core layer, a first reinforcement layer and a second reinforcement layer. The core layer is arranged between the first reinforcement layer and the second reinforcement layer and includes a honeycomb structure produced in particular from polypropylene (PP). It is conceivable that the first reinforcement layer and/or the second reinforcement layer each include a meshwork made of a plurality of thermoplastic continuous fiber tapes (UD tapes).

Abstract: An electric vehicle or hybrid vehicle (1) has an inductive charging device (2) and a battery (3) chargeable therewith. The inductive charging device (2) has at least one catch element (4), via which it is connected to a vehicle body (5). The inductive charging device (2) is configured to be ejected from the electric vehicle or hybrid vehicle (1) in the event of a crash and to be held outside the electric vehicle or hybrid vehicle (1) via the at least one catch element (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.

Abstract: An air guide device for a motor vehicle having an air guide element and a movement mechanism. The air guide element forming a rear side part of a body of the motor vehicle so as to be movable relative to the remaining body. The air guide element is movable between an inoperative position and at least one operating end position. The air guide element, in its inoperative position, is flush with the remaining body. The rear side part has a flow guide surface which faces an environment of the motor vehicle and along which air flows.
