The external attachment includes a locking element that prevents the fastened external attachment from being pushed back and is only unlockable from the inside.

Abstract: A method for operating a motor vehicle which has at least two axles, a braking system with at least four wheel brakes, which are arranged on a front axle and a rear axle, and which has a data processing device. A braking force distribution is specified by the data processing device. A front braking force component for the front wheel brakes and a rear braking force component for the rear wheel brakes are specified by the braking force distribution, and the braking force distribution is adapted to improve the NVH characteristics of the motor vehicle if it is determined by means of the data processing device that a specified condition is fulfilled for an acoustically perceptible release of a tension in the motor vehicle. The braking force distribution is adjusted by reducing the front braking force and increasing the rear braking force.

Abstract: A method for operating a motor vehicle includes minting a non-fungible token (NFT), which links an identifier for a first, in particular prominent, user with an identifier for the motor vehicle, and with data for describing a setting made by or for the first user, as well as the later reading of the data describing the settings made from the NFT based on the identifier for the motor vehicle, and the setting is restored for use by a second user on the same motor vehicle.

Abstract: A movable door leaf of a vehicle door. Depending on an actuating force exerted on the door leaf, an electric drive device is activated to influence the pivoting of the door leaf between an open position and a closed position. When influencing the pivoting of the door leaf, a movement characteristic of the door leaf is detected depending on the actuating force and compared with a predetermined movement characteristic. The predetermined movement characteristic replicates the operating force of an operator for the manual pivoting of the door leaf. Depending on the comparison result, an obstacle detection device is activated to detect obstacles within a predetermined pivoting region of the door leaf. When an obstacle is detected in the pivoting region, a collision avoidance measure is initiated by the obstacle detection device to limit an unwanted collision with the detected obstacle when the door leaf pivots.

Abstract: A movable door leaf of a vehicle door. An electric drive device is activated to influence the pivoting of the door leaf, at least partially, between an open position and a closed position, depending on an actuating force exerted on the door leaf. When the drive device is activated, an obstacle detection device is also activated to detect obstacles in a predetermined pivot range of the door leaf. When an obstacle is detected in the pivot range, an object classification algorithm is performed using the obstacle detection device to identify the object class of the detected obstacle. Depending on the identified object class, a collision avoidance measure is initiated by the obstacle detection device to limit an unwanted collision with the detected obstacle when pivoting the door leaf.
