摘要： A control unit for a motor vehicle, having a supply connection for receiving a supply voltage from a supply line needing to be secured against a reaction from the control unit, wherein to protect against the reaction there is provision in a current path of the supply connection for a unidirectional first blocking element, and a diagnostic circuit is configured to check the blocking effect thereof by a predetermined diagnostic routine. An additional, second unidirectional blocking element is connected in series with the blocking element in the current path of the supply connection, wherein the first and the second blocking element each provide for a unidirectional flow of current to the device circuit, and the diagnostic circuit is configured to use the diagnostic routine to also check the blocking effect of the second blocking element.

摘要： A method removes brightening, which is caused by scattered light, from an image of an external environment of a vehicle captured by a vehicle camera arranged in or on the vehicle. A curve of a total intensity e.g. along a respective line within the image is determined, wherein the total intensity is caused by desired light and scattered light that reach the coverage area of the vehicle camera. An approximation function of a lower limit of the scattered light intensity is estimated. The estimated approximation function is subtracted from the determined curve of the total intensity to produce a modified image with reduced or corrected scattered light.

摘要： An apparatus and a method for bundling two data channels via a point-to-point connection, is described herein. Sequences of data from a first data channel are transmitted via a first line and sequences of data from a second data channel are transmitted via a second line to a multiplexing apparatus. A data gap having a predefined size is arranged between two sequences of first data in each case. The data from the second data channel are transmitted to a buffer and, if the buffer has been filled with second data having a predefined size, are inserted into the data from the first data channel. A third data channel is formed at the output of the multiplexing apparatus using these first data and second data and is transmitted to a third line. The third data channel therefore has a bundling of sequences of first data and sequences of second data.

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： A camera device (2) for detecting a surrounding region (7) of a vehicle includes an optronic unit (3) configured to capture an image sequence of the surrounding region. The optronic unit includes a wide-angle lens and a high-resolution image sensor. The optronic unit is configured to reduce the resolution in images in the image sequence, in particular by pixel binning, alternatingly differently and asymmetrically in successive images of the sequence.

摘要： A method and a device for determining the position of a vehicle, said method comprising the steps: recording sensor data from the ground over which the vehicle travels; extracting ground characteristics of the ground over which the vehicle travels from the recorded sensor data or from occupancy grids which are calculated on the basis of the sensor data; determining the current position of the vehicle on the basis of the extracted ground characteristics using a characteristic map.

摘要： A pneumatic valve, including a valve housing with an air chamber with one or more air ports. A respective air port of at least one of the air ports can be opened and closed by a movable valve flap which is mechanically coupled to a shape memory alloy. The SMA element deforms as a result of supplying electrical heating current and effects a predefined movement of the valve flap for opening or closing the respective air port. The deformation of the SMA element is reversed when the supply of the electrical heating current ends. The valve flap has a leaf spring. The leaf spring is held rotationally fixedly relative to the valve housing. The leaf spring interacts with the SMA element such that a stroke of the SMA element caused by the deformation is converted into a stroke of the valve flap by elastic bending of the leaf spring.

摘要： A surround view system for a vehicle includes a processor (10) and cameras (2 to 5) that can be arranged on the vehicle so that the cameras (2 to 5) can record images of an outside environment of the vehicle. The processor is configured to analyze a position (α) and/or a movement of a movable part (14) of the vehicle (1) and to generate a composite image of the outside environment from individual images recorded by the cameras. Furthermore, the processor is configured to calculate an image processing region within the composite image for an adaptive image processing, to determine, based on the analyzed position and/or movement of the movable part (14), that a back-projection of the movable part (14) goes beyond the image processing region, and to modify the image processing region so that the back-projection of the movable part (14) is within the modified image processing region.

摘要： In a method for determining a transition between two display images, a two-dimensional initial image is mapped by first and second mapping functions respectively onto first and second mapped images, and the first and second mapped images are mapped respectively onto a first display image. The initial image is mapped by an interpolating mapping function onto an interpolating mapped image in the model space, wherein the interpolating mapped image is determined by interpolation of the first and second mapped images as a function of an interpolation parameter. The initial image, mapped by the interpolating mapping function onto the interpolating mapped image, is mapped onto an interpolating display image which transitions from the first display image to the second display image through variation of the interpolation parameter.
