A computer-implemented method for classifying an input signal that is ascertained as a function of an output signal of a sensor as to whether or not it has an anomaly, it being decided, as a function of an output signal of an autoencoder () to which the input signal is supplied, whether or not the input signal has the anomaly. The autoencoder has at least one encoder and at least one decoder. An intermediate variable is ascertained as a function of the input signal by the encoder, and the output signal is ascertained by the decoder as a function of the intermediate variable. The autoencoder provides, for the input signal supplied to it, a plurality of hypotheses of formula for the reconstruction of the input signal, and the output signal is ascertained as a function of this plurality of hypotheses of formula.

Method and device for determining a control signal

A radar sensor for motor vehicles. The radar sensor includes an antenna arrangement having multiple antenna elements linearly arranged at uniform distances along a connecting line, the distance between each two adjacent antenna elements being equal to half of the mean wavelength λ of the emitted radar signal, and the arrangement including at least one triple of adjacent antenna elements, in which the two antenna elements located on the outside in the triple, on the one hand, and the interposed antenna element, on the other hand, originate in opposite directions from the connecting line. The antenna arrangement includes at least one pair of antenna elements which originate in opposite directions from the connecting line and whose distance from one another is an integer multiple of the wavelength λ, so that one of these antenna elements has a negative amplitude taper in relation to the antenna elements of the triple.

Radar sensor for motor vehicles

A radar sensor system is provided. The radar sensor system includes: at least two radar sensors each having at least one transmitter and at least one receiver, detection regions of the two radar sensors overlapping at least partially. The two radar sensors are situated at a defined distance from one another. Transmit signals of the two radar sensors are synchronizable in such a way that radiation of one radar sensor that was emitted by the respective other radar sensor and reflected by an object is capable of being evaluated by an evaluation device.

A method for tire inspection which includes taking at least one image of at least one first area of a tread of a tire that is to be inspected; determining the profile depth of a second area of the tread of the tire, the second area being included in the first area; and displaying the profile depth of the at least one image of the at least one first area and the position of the second area in the first area. The method may additionally include automatically analyzing the images taken of the tread, so as to arrive at statements on the condition of the tread.

Optical device and method for inspecting tires

A device for recognizing the inscription on the wall of a tire, including a driving surface plane, at least one directional light source to illuminate the tire; at least one camera to record multiple images of a wall of the tire rolling on the driving surface plane; and an evaluation device to synthesize an image of the wall of the tire from the multiple recorded images and to evaluate the synthesized image with the aid of a text recognition method.

A radar sensor emits microwave radiation and receives partial radiation reflected at objects within the sensor detection range, a plurality of antennas being provided for the transmission and reception in each case, and the transmission power of the outer antennas being lower than the transmission power of the inner antennas. This is accomplished by reducing the transmission power with the aid of couplers, the couplers advantageously being implementable as Wilkinson power splitters.
