Patent number: 11493624Abstract: 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.Type: GrantFiled: September 12, 2018Date of Patent: November 8, 2022Assignee: Robert Bosch GmbHInventors: Christian Passmann, Daniel Zaum, Peter Christian Abeling

Publication number: 20210063169Abstract: A method and a corresponding device are described for creating a first map. The method includes receiving surroundings data values representing surroundings of a vehicle, the surroundings encompassing at least one surroundings feature, the surroundings data values being detected using a first surroundings sensor system of the vehicle. The method also includes determining an object class of the surroundings feature, as a function of the first surroundings sensor system of the vehicle, and creating an assignment of the object class to at least one further object class. The further object class is determined proceeding from at least one further surroundings feature, the further surroundings feature being detectable with using a second surroundings sensor system. The second surroundings sensor system is not identical in design to the first surroundings sensor system. The method also includes creating the first map, as a function of the surroundings data values, based on the assignment.Type: ApplicationFiled: August 16, 2018Publication date: March 4, 2021Inventors: Peter Christian Abeling, Christian Passmann, Daniel Zaum

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.Type: GrantFiled: January 26, 1999Date of Patent: August 17, 1999Assignee: Robert Bosch GmbHInventors: Christian Passmann, Thomas Wixforth
