Patent number: 11255676Abstract: A sensor system, having sensor elements for sensing at least to some extent different primary measured variables or use different measurement principles. A signal processing device evaluates the sensor signals from the sensor elements at least to some extent collectively and rates the information quality of the sensor signals. The signal processing device further provides a piece of information about the consistency of at least one datum of a physical variable, wherein this datum of the physical variable is calculated, at least to some extent, on the basis of the sensor signals from sensor elements that sense this physical variable directly or from the sensor signals from which it is possible to calculate this physical variable.

Patent number: 10753748Abstract: A system corrects errors of a measurement system. The system comprises base measurement system BS and a correction system. BS sensor data is acquired and provided to an algorithm. The data is stored associated with a time stamp indicating time of sensing. Output values are calculated and stored with time stamps indicating time of the sensor data upon which the output values are calculated. Data having corresponding time stamps are supplied to a filter where correction values and correction increments are calculated. The correction increments reflect the change of error in a base system output value over time due to integration or summing up BS sensor data errors in the processing algorithm. The correction values are applied to the BS data and corrected base navigation output values are calculated. These output values are corrected by the correction increments. Output values of the processing algorithm are further processed in succeeding applications.Type: GrantFiled: April 18, 2017Date of Patent: August 25, 2020Assignee: HONDA RESEARCH INSTITUTE EUROPE GMBHInventor: Nico Steinhardt

Patent number: 10495483Abstract: A method and system for initializing a sensor fusion system is disclosed, wherein the sensor fusion system includes a base system and at least one correction system. Measured values are captured by the base system and by the correction system, and the measured values directly or indirectly describing physical quantities are afflicted with error values. The error values describe deviations of the measured values from the described physical quantities, and at least the physical quantities indirectly described in the measured values of the base system and the error values of the physical quantities cannot be determined during initialization. The measured values are continuously fused into a fusion data set after initialization. For at least one of the physical quantities associated with the measured values of the base system and the error values of the physical quantities, starting values are determined from the measured values of the correction system.Type: GrantFiled: December 9, 2016Date of Patent: December 3, 2019Assignee: Continental Automotive Systems, Inc.Inventor: Nico Steinhardt

Patent number: 10422658Abstract: A method, a system, and a use of the system, for fusing sensor signals with different temporal signal output delays into a fusion data set. Each of at least three different sensor signals describe a measured value of at least three different sensor systems. The signal output delays are unique to the sensor. Each sensor signal includes a timestamp describing a detection time of the measured value. Erroneous measured values of a first sensor system are determined by a comparison with the measured values of other sensor systems. The erroneous values are considered constant at least for the duration between two consecutive comparisons. The erroneous values and/or the measured values are available for a specified time. The erroneous values and/or the measured values of the first sensor system constant are corrected by a correction process, and corrections carried out during the time period are considered when applying additional corrections.Type: GrantFiled: November 19, 2014Date of Patent: September 24, 2019Assignee: Continental Teves AG & Co. oHGInventor: Nico Steinhardt

Patent number: 10378901Abstract: A navigation system comprises a base system and at least one correction system, wherein the base system and the correction system each capture measured values. The measured values describe navigation data and are each burdened with error values. The error values describe discrepancies in the measured values from the described navigation data. The error values of the measured values of the base system are recognized by the measured values of the correction system. The recognition is effected by considering a capture uncertainty in the correction system. The consideration represents adaptation of parameters of a stochastic noise model, which prescribes a weighting for measured values of the correction system with respect to measured values of the base system in accordance with the parameters. The adaptation of the parameters is chosen on the basis of the capture uncertainty in accordance with a characteristic curve or a family of characteristic curves.Type: GrantFiled: December 9, 2016Date of Patent: August 13, 2019Assignee: Continental Teves AG & Co.

Patent number: 10168158Abstract: The invention regards a navigation system and a method for error correction. The navigation system comprises a base navigation system and a correction system. Measurement uncertainties are assigned to each measurement and an error threshold is computed on the basis of these uncertainties. Redundant measurements are determined and residuals for at least a pair of redundant measurements as a discrepancy measure are calculated. In case that the residual exceeds a respective threshold an error count for each measurement involved in the determination of the residual is increased. All residuals for each measurement are summed up for a particular measurement and for carrying out the correction in a fusion filter measurements are selected on the basis of their respective error count and summed up residuals.Type: GrantFiled: April 19, 2017Date of Patent: January 1, 2019Assignee: HONDA RESEARCH INSTITUTE EUROPE GMBHInventor: Nico Steinhardt
