Abstract: A method for selecting at least one connection pattern drivable by road users using a control device. Trajectory data are received from at least one area. On the basis of the received trajectory data, starting points and end points of drivable trajectories are determined. All the connection patterns between the starting points and the end points of the drivable trajectories are determined in the form of connecting lines. The determined connection patterns are filtered by at least one filter. Connection patterns remaining after filtering are compared with route profiles from the trajectory data. For each remaining connection pattern a number of route profiles which correspond to the connection pattern are counted. A connection pattern with the highest number of matching route profiles is selected. A control device, a computer program, and a machine-readable storage medium are also described.

Abstract: A method for creating map data having lane-specific resolution. Mapping data are initially received, the mapping data being transmitted by a vehicle, and including a vehicle trajectory and at least one object feature. Once the mapping data has been received, it is checked whether map data for local surroundings of the received mapping data are present. In the event the check indicates that no map data are present, map data are created from the mapping data and stored in a memory. In the event the check indicates that map data are already present, the map data are compared with the mapping data. If this comparison reveals that the mapping data differ from the map data, the map data are adapted, the adaptation taking place on the basis of a weighting factor. The adapted map data are subsequently stored in the memory.

Abstract: A method for generating ultrawideband pulsed microwave signals from optical field ionization of a gas with an ultrashort laser pulse, where the amplitude and frequency of the signals can be controlled via the characteristics of the laser pulse and/or the gas. The center frequency of the spectrum of the microwave signal can be controlled by changing the laser pulse energy. The amplitude of the microwave signal can be controlled by changing the wavelength of the laser pulses. The amplitude and frequency of the microwave signal can be tuned by controlling the pressure of the gas medium. The location at which the microwave signal is generated can be controlled by controlling the location at which the laser pulse creates a plasma. Interference among microwave signals resulting from multiple laser-produced plasmas can be used to construct an ultrawideband microwave signal having a predetermined amplitude and frequency.
