A method and device for operating a vehicle comprising a step of recording environment data values, which represent an environment of the vehicle, the environment comprising at least one environmental feature; a step of determining a comparative value of a comparison between the at least one environmental feature and a map, the map comprising at least one map feature, the at least one environmental feature corresponding the at least one map feature; a step of determining an up-to-dateness of the map, based on a comparison of the comparative value with a threshold value; and a step of operating the vehicle, as a function of the up-to-dateness of the map.

Method and device for operating a vehicle

A method and a system for mapping a surroundings of at least one vehicle and for locating the at least one vehicle. Measurement data of the vehicle's surroundings are ascertained by at least one radar sensor of the at least one vehicle, the measurement data of the at least one radar sensor being aggregated. The aggregated measurement data are compared with already existing aggregated measurement data. The aggregated measurement data are optimized by reducing measurement errors based on the comparison between the aggregated measurement data and the already existing aggregated measurement data. A map is generated or updated on the basis of the optimized aggregated measurement data, and the at least one vehicle being located on the generated or updated map by comparing the ascertained measurement data with the generated map.

Method and system for mapping and locating a vehicle based on radar measurements

In a method and a device for creating and providing a map, a highly accurate map that includes multiple highly accurate map features is obtained, a shared map feature attribute is determined as a function of the multiple highly accurate map features, a derivative map is created as a function of the shared map feature attribute, and the map is output.

Method and device for creating and providing a map

In a method and a device for preparing and providing a highly accurate map, steps are performed which include receiving first surroundings data values that represent first surroundings of at least one vehicle and that are detected using a surroundings sensor system of the at least one vehicle; receiving second surroundings data values that represent second surroundings of at least one traffic infrastructure area and that are detected using at least one traffic infrastructure sensor; generating the highly accurate map based on the first and second surroundings data values, and outputting the highly accurate map.

Method and device for establishing and providing a high-precision card

A radar device having means for generating a carrier-frequency signal, means for shaping pulses, means for generating modulated radar pulses from the carrier-frequency signal, means for emitting modulated signals as radar pulses, means for receiving radar pulses and means for processing the received radar pulses. The means for receiving the radar pulses have an array including a plurality of antennas, the means for processing the radar pulses have means for dividing the signal power over at least two different reception branches. Means are provided for generating different directional characteristics in the various reception branches.

Radar device and method for operating a radar device

A method and apparatus for calibrating transmission and reception paths of a group antenna with an adaptive radiation pattern is provided, in which one transmission signal after the other is transmitted over each transmission path (DA1, . . . ,DAN; Tx1, . . . ,TxN; DP1, . . . ,DPN), a signal portion is decoupled from each transmission signal and the decoupled portion of at least one transmission signal is divided into as many equal parts of equal strength and equal phase as reception paths present. These equal parts of the decoupled transmission signal portion are coupled into the respective reception paths and the strengths and phases of the equal parts transmitted over the respective reception paths (DP1, . . . ,DPN; Rx1, . . . ,RxN; AD1, . . . ,ADN) are measured. The transmission factors of all other ones transmission paths and reception paths are determined from known transmission factor values for them and the measured strengths and phases of the equal parts of the at least one transmission path. Deviations of the resulting transmission factors are compensated by changing weighting factors of a radiation pattern network (Tx-BFN, Rx-BFN).
