摘要： The invention relates to a method for detecting beacons (4) in the surroundings of an ego vehicle (5), comprising the steps of:
capturing (S1) a sequence of camera images (1) of a section of the surroundings by means of a-camera system (6) of the ego vehicle (5),
detecting (S2) bright light spots in the recorded camera image (1),
cutting out (S3) regions (3) containing the detected bright light spots in the camera image (1),
classifying (S4) the cut-out regions (3),
classing (S5) the bright light spots as beacons (4) if the classified bright light spots are detected repeatedly and therefore a threshold value of a counter is exceeded.-

摘要： An example embodiment of the present disclosure relates to a method for monitoring the position of a connection cable of a trailer, having the steps of:
capturing a region which lies behind a motor vehicle using a camera,
processing the captured image data using an analysis unit, detecting the connection cable, and determining the position of the connection cable,
comparing the captured position of the connection cable with a secure position of the connection cable,
and outputting a warning signal if the captured position of the connection cable deviates from the secure position.
Another example embodiment additionally relates to a camera system and to a motor vehicle including a camera system.-

摘要： A method for determining and specifying necessary closing speed of a motor-operated vehicle door at the moment of reaching an initial closure detent by means of a control unit is described. The motor current of the door motor is determined and compared with a calculated maximum current, wherein the maximum current results from a motor armature resistance measured at the start of the door movement, from a minimum supply voltage of the control unit and from an adjustable factor. If the determined current is higher than the maximum current, the value of an adaptation table is changed and a higher closing speed is specified by the control unit for the next closing movement of the vehicle door; and, if the determined current is lower than the maximum current, a lower closing speed is specified by the control unit for the next closing movement of the vehicle door.

摘要： Disclosed is an actuator unit for opening or closing a valve opening of a valve for a pneumatic adjusting device of a vehicle seat, comprising a circuit board with a top side extending in a circuit board plane, an actuating element with an actuating section for opening or closing the valve opening and a bending section connected to the actuating section, and an actuator element with a first end mechanically connected to the actuating section and a second end mechanically connected to the circuit board. The actuator element is configured to, when actuated, bend the bending section such that the actuating section is moved between a first position for opening the valve opening and a second position for closing the valve opening. The actuating section is arranged on a first side and the bending section is arranged on a second side, situated opposite the first side, respective of the circuit board plane.

摘要： The invention relates to a method for operating ultrasonic sensors) for a motor vehicle, including emitting a plurality of ultrasonic signals by respective ultrasonic sensors. The ultrasonic signals include a sequence of elementary signals. The elementary signals have signal pauses and a plurality of different signal pulses. The ultrasonic signals differ from one another by the sequence of the elementary signals. The method further includes receiving reflected ultrasonic signals, wherein the received ultrasonic signals are associated with the emitted ultrasonic signals on the basis of the sequences of the elementary signals.

摘要： The invention relates to a method for detecting the position of a bus subscriber (2, 2a, 2b, 2n) of a bus system, in which a control device (1) and several bus subscribers (2, 2a, 2b, 2n) are provided. The bus subscribers (2, 2a, 2b, 2n) are respectively in a position (P1, P2, Pn) to be detected and are connected to the control device (1) via at least one line, the line to the respective bus subscriber (2, 2a, 2b, 2n) having a definable line length (L1, L2, Ln), and the position of a bus subscriber (2, 2a, 2b, 2n) is then detected in that the control device (1) sends a signal via the line to the respective bus subscriber (2, 2a, 2b, 2n) within a measurement cycle and the bus subscriber (2, 2a, 2b, 2n) responds. The measurement cycle duration is determined and a ratio of measurement cycle duration and line length (L1, L2, Ln) is used to detect the position.

摘要： The exemplary embodiments relate to a parking assistance system for a vehicle, designed to present surroundings of the vehicle. The parking assistance system can include at least one camera designed to record at least one image. The parking assistance system may use a grid structure to present the surroundings of the vehicle for a user. Additionally, the parking assistance system may have an image evaluation unit designed to determine the relative position and the orientation of another vehicle depicted in the image. Additionally, the image evaluation unit may be designed to adapt a grid structure on the basis of the determined orientation of the other vehicle, with the image being projected onto the adapted grid structure.

摘要： A method for creating a road model for a driver assistance system of an ego vehicle includes recording the surroundings of the ego vehicle with at least one environment detection sensor. The method also includes detecting static and/or dynamic objects and creating a grid map having a plurality of grid cells. Static objects are entered into the grid map as occupied grid cells. The method also includes tracking the static objects and/or the dynamic objects. Information regarding a road profile is deduced based on the detections entered in the grid map and the tracked objects. A road model with the deduced information is created. The road model is provided to at least one driver assistance system.
