The invention relates to a method for analyzing trafficability using a computer, said method comprising the following steps: receiving image data of surroundings (10) in front of a vehicle (S10), analyzing the image data to identify different zones (12, 14, 16, 18, 24) in an image of the surroundings (S12, S14, S16, S18, S20); and analyzing identified different zones (16, 18) in terms of trafficability for the vehicle (S22, S24).
摘要:
Using a radar system in a motor vehicle, high frequency individual signal pulses are transmitted from at least one transmitting antenna, and at least one receiving antenna receives reception signals formed by reflection of the transmitted signal pulses from objects in the surroundings. The reception signals are mixed with the high-frequency signal to produce low-frequency mixed signals representing the sequence of individual signal pulses. The phase angle of the mixed signals is varied over successive individual signal pulses thereof by varying the phase angle of: the successive individual transmitted signal pulses, the high-frequency signals used for the mixing, and/or the mixed signals. In further processing of the mixed signals to determine the distance and the relative velocity of detected objects, an interference component can be separated and/or suppressed from a useful signal component because the useful signal component has the known phase angle variation but the interference component does not.

A method combines a road sign recognition system and a lane detection system of a motor vehicle. The road sign recognition system generates road sign information from sensor data of a camera-based or video-based sensor system and the lane detection system generates lane course information from the sensor data. Meaning-indicating data for road signs are generated from the lane course information, and are used to check the plausibility of and/or to interpret the road sign information. Data indicating the course of the lane are generated from the road sign information, and are used to check the plausibility of and/or to interpret the lane course information.
摘要:
A driver assistance system includes a sensor that detects objects and/or characteristics of objects in the surroundings of a motor vehicle, and an object recognition unit that evaluates data from the sensor to produce object information, and determines a confidence value indicating the probability of accuracy thereof. If the confidence value is greater than a minimum threshold but less than a predefined threshold, then the system displays the object information to the driver, who confirms or rejects it, e.g. by actuating or not actuating an operating element. Upon confirmation by the driver, the system begins or continues to perform a driver assistance function based on the object information. Upon rejection by the driver, the system does not perform or discontinues the driver assistance function based on the object information. If the confidence value exceeds the predefined threshold, then the system autonomously performs the driver assistance function.

In a motor vehicle with an adjustable coupling (intermediate device) between the (crank)shaft and floor contact elements (wheels), wherein the coupling is set in trailing throttle mode in such a way that the rotational speed of the shaft is reduced, in particular is adjusted to a predefined value, in order to reduce the internal losses of the drive, in particular an internal combustion engine.
摘要:
For recognizing road signs, a camera captures image data of the surroundings of a vehicle. The image data are analyzed to determine a region that contains a potential road sign. The image region is evaluated by a first classification unit to identify a road sign belonging to a particular class based on a recognized class-specific feature. Then, the brightness or color intensity of at least a portion of the road sign is analyzed along radially extending scanning beams, to determine potential contour points of an information-bearing part of the road sign, which is then extracted and semantically interpreted in a second classification unit to determine the information content thereof.

A method and system produce a warning signal to warn a driver of a vehicle about a potential obstacle crossing behind the vehicle, for example as the vehicle is backing out of a parking space. The system and method use a sensor to detect, monitor and track the position and velocity of a potential obstacle relative to the subject vehicle, in a detection space behind and to the sides of the vehicle, preferably to predict the probability that the trajectory of the potential obstacle will intersect with the trajectory of the subject vehicle at a critical time.

A filter element for a pneumatic adjusting arrangement, e.g., a vehicle seat, includes a filter chamber that is fillable with pressure media and includes first and second flexible films connected together along a connecting seam to define the filter chamber. A filter medium for removing particles entrained in the pressure medium is arranged in the filter chamber and separates the filter chamber into first and second chamber regions. The pressure medium may flow into the first chamber region via a pressure medium inlet line, flow into the second chamber region via the filter medium, and flow out of the second chamber region via at least one pressure medium outlet line. By realizing the filter element or the filter chamber thereof from flexible films, the filter element can be installed in a space-saving manner and with a form that can be adapted to the situation.
摘要:
A circuit board has a plurality of circuit board layers that are arranged one over the other, and that each include an electrically insulating base material having a glass transition temperature greater than or equal to 170° C. The circuit board layers each further have at least one thermally conductive layer applied to the base material. Several vias extend through respective ones of the circuit board layers to connect thermally conductive layers of different circuit board layers, such that the vias and the thermally conductive layers form a thermally conductive bridge from a topmost circuit board layer to a bottommost circuit board layer.
