摘要:
A multibeam radar sensor is proposed in which a holder (of resilient construction) for polyrods, in connection with a spacing element, holds the polyrods fixedly at a predetermined spacing, preferably in the range between 0 mm and 0.2 mm. The stays of the holder are fashioned such that a spring force constantly presses the spacing element against the base plate. In this context, the spring force is chosen such that the maintenance of the predetermined spacing a is ensured even under disadvantageous operating conditions such as vibration, shock, and impact.
摘要:
A multi-beam radar sensor having at least two transmitting/receiving patches, in which the patches, assigned polyrods, and/or a dielectric lens are configured so as to be asymmetrical. As a result of this asymmetrical arrangement, asymmetrical beam paths result for the transmitting and receiving beams. These asymmetrical beam paths cause the average error amount in the angle measurement of the radar sensor to be less than in the case of a symmetrical arrangement.

A device for mounting a distance sensor, in particular a proximity radar device, on a motor vehicle, the distance sensor being accommodated in a closed housing, the housing being moveably attached to a support and the support being attachable in an immoveable manner to the motor vehicle. The device is characterized in that the housing is attachable to the support by at least three screws arranged in an L-shape relative to each other, that the screws, in the installed state of the distance sensor, are able to be screwed from its front side, and that a screw-out protection is provided for at least two of the screws.

A folding shutter arrangement having three or more rigid folding shutter elements having element edges that bend out and element edges that do not bend out in alternation. A first folding shutter element can be fastened to a building so as to be pivotable about a first axis near a element edge that does not bend out. A second folding shutter element is pivotably retained about a second axis near a second element edge that does not bend out. Adjacent folding shutter elements are pivotably connected to each other in pairs at the third element edges by a bend-out joint. A driving element is provided which drives at least one of the element edges in the opening or closing direction, and which forcibly pivots the folding shutter elements connected to at least one of the element edges that do not bend out.
摘要:
In a folding shutter arrangement having three or more inherently rigid folding shutter elements (12) having element edges that bend out and element edges that do not bend out in alternation, a first folding shutter element (12A) is or can be fastened indirectly or directly to the building (1) so as to be pivotable about a first axis (12A′), which is stationary or nearly stationary with respect to a building (1), near a (first) element edge (13A) that does not bend out. A second folding shutter element (12B) is pivotably retained about a second axis (12B′), which can be moved perpendicularly to itself, near a second element edge (13B) that does not bend out, and can be moved along guides (16A, 16B) arranged perpendicular to the second element edge (13B) in pairs. Adjacent folding shutter elements (12A, 12B; 12C, 12D; . . . ) are pivotably connected to each other in pairs at the third element edges (15A, 15B) thereof, which bend out and which are opposite from and parallel to the first and second element edges (13A, 13B; . . . ), by means of a bend-out joint (14A, 14B; . . . ). Additional folding shutter elements are connected in pairs to the preceding folding element pair and/or a last folding shutter element freely protruding at the end is pivotably connected to the folding element pair(s) near the second, fourth, or further element edge (13B; . . . ) that does not bend out. At least one driving element (30) is provided, which can be moved along at least one of the guides (16A, 16B) and which drives at least one, preferably the last, of the second, fourth, or further element edge (13B, . . . ) that does not bend out, in the opening or closing direction, and which forcibly pivots the folding shutter elements (12B, 12C; . . . ) connected to at least one of the element edges (13B; . . . ) that do not bend out, in pairs in the opening or closing direction by means of at least one coupling element (32A, 32B, 32C).
摘要:
A method and a device for warning the driver of a motor vehicle. An object detector is provided, which detects preceding vehicles and ascertains their distance and relative velocity with respect to the host vehicle and supplies these to an evaluation device. The evaluation device assumes that the preceding vehicle would perform a deceleration and ascertains as a further function of the variables measured by the object detector and the driver's reaction time and the host vehicle's maximum possible deceleration whether a collision with the preceding vehicle would be avoidable. If an unavoidability of a collision is recognized, then a driver warning device is activated.
摘要:
A radar system for motor vehicles, having an antenna, a first processor which is developed to transform signals supplied by the antenna via a primary signal path into a spectrum, and a second processor for the additional evaluation of the spectrum, wherein at least a part of the signals received by the antenna is able to be supplied to the second processor via a redundant signal path while by-passing the first processor, and the second processor, on its part, is designed to transform these signals into a spectrum.
摘要:
A device for a front-end component part of a motor vehicle, behind which a radar transmitter/receiver is fastened in such a way that the latter is not visible from in front. In winterish surroundings, ice and snow deposits may occur on the front component part, whereby the functionability of the radar sensor may be impaired. It is possible to remove and/or prevent these precipitation deposits on the front component part.

摘要:
The present invention relates to a method and an apparatus for adjusting the alignment of a beam characteristic of a distance sensor, in particular of a proximity radar for a motor vehicle. An apparatus for positioning a motor vehicle, preferably a headlight aiming device, is joined to the target object for the distance sensor. Also provided is a service unit with which measured values or data of the distance sensor can be read out. On the basis of at least one predefined criterion, the measured values or data are analyzed in such a way that necessary displacement directions of the distance sensor can be displayed by way of the service unit. Preferably the capability of the distance sensor to determine angular positions of detected target objects is utilized. Otherwise adjustment is performed to predefined reception levels.
