摘要:
The invention relates to a method for determining the plausibility of objects in driver assistance systems for motor vehicles, two variables (Tr, Tv) being derived from positioning data (14, 20) from two object positioning systems (10; 16, 18) of the vehicle, operating independently of each other, for an object that is detected by both positioning systems, one variable for each positioning system, representing one and the same physical parameter (TTC), and subsequently the two variables being checked for consistency, characterized in that the parameter (TTC) is the pre-calculated time until collision of the vehicle with the object.

In a radar system, a switcher is provided for switching over between at least two different directional characteristics, in particular for different distance ranges, of at least two transmitting antennas. On the receiving side, a combined evaluation of the digitized signals of at least two receiving antennas is performed, in the manner of a correlation of the receiving antenna signals.

The invention relates to a method for checking a network that consists of nodes and devices connected to said nodes. The inventive method comprises the following steps: detecting the network topology with at least the node number, node identity and circuitry of node inputs and node outputs; comparing the actual network topology with a permanently saved reference network topology for the network in order to detect any changes in number and/or kind of the devices connected to the network, in network topology and/or in the nodes at which a modification can be detected. In a preferred embodiment, the reference topology can be restored by deactivating the nodes, node outputs and/or devices at the node outputs as far as they are not provided for in the reference network topology. The respective preferred network is a standard IEEE 1394 network.

摘要:
The invention relates to a mehod for estimating the relative movement of video objects in a driver assistance system for motor vehicles, which is equipped with a video system, wherein at least one parameter characterizing the movement is calculated based on the apparent movement of the object in the video image. According to the invention, the parameter characterizing the movement is calculated on the basis of the optical flow that is integrated in the video image on the object surface.

The invention relates to a method for coding traffic disruptions along a distance based on a digital map during which information regarding disruptions in the direction along the distance is considered and transmitted to the navigation system. The invention is characterized in that coded information concerning the existence or non-existence of disruptions on side streets or intersections along the distance are additionally transmitted. The invention also relates to a method for dynamically calculating routes during which coded information concerning the existence or non-existence of disruptions on side streets or intersections along the direction of the coded route is transmitted and drawn upon for calculating routes.
摘要:
A transmitting device for electromagnetic radiation comprises a waveguide having an input for coupling an electromagnetic wave into the waveguide and a plurality of openings in the waveguide for emitting the electromagnetic wave. A drivable closure element is provided for selectively closing at least one of the openings with respect to the electromagnetic radiation.
