Abstract: A method for comparing two digital representations of driving situations of a vehicle. The digital representations include occupancy information about an occupancy of the environment of the vehicle by traffic-relevant objects. The method includes: subdividing a region of the environment of the vehicle into a grid of subregions; ascertaining, based on the occupancy information in the first digital representation, the occupancies of the subregions by traffic-relevant objects, and combining them to form a fingerprint of the first driving situation; ascertaining, based on the occupancy information in the second digital representation, the occupancies of the subregions by traffic-relevant objects, and combining them to form a fingerprint of the second driving situation; ascertaining a similarity measure between the first fingerprint and the second fingerprint according to a predefined dimensional rule; determining that the two driving situations are identical or at least similar if the similarity measure satisfies the similarity measure.

Abstract: A method for quantitatively characterizing at least one temporal-sequence (TS) of an object-attribute-error of an object, for at least one scenario of a plurality of scenarios; the object having been detected by a sensor of a plurality of sensors; including: providing at least one TS of sensor-data of a plurality of TSs of sensor-data of the sensor, for the at least one scenario; determining a TS of at least one object-attribute of the object with the TS of sensor-data; providing a sequence of a reference-object-attribute of the object of the scenario, corresponding to the TS of the object-attributes; determining a sequence of object-attribute-difference by comparing the sequence of the object-attribute to the sequence of the reference-object-attribute of the object; generating an error-model for describing TSs of object-attribute-errors of objects; the object having been detected by the sensor, with the TS of the object-attribute-difference, to quantitatively characterize the object-attribute-error.

Abstract: A computer-implemented method for comparing generated data sequences for an at least semi-automated driving of a mobile platform, which were generated with the aid of a closed-loop simulation process, and a recorded data sequence of a trip of the mobile platform, controlled in at least semi-automated fashion, for the qualification of the control. The method includes: providing the recorded data sequence, which is based on a multiplicity of determinants, of trips of the mobile platform controlled in at least semi-automated fashion; providing a multitude of generated data sequences, which are based on the multiplicity of determinants, of simulated trips, which were generated with the aid of the closed-loop simulation process; providing similarity limits and a similarity metric for the respective determinant; comparing the recorded data sequence to each individual generated data sequence of the multitude of recorded data sequences.

Abstract: A computer-implemented simulation method is described for testing a driving program for the at least partial autonomous guidance of a test vehicle. The test vehicle is moved by the driving program on a simulated road. A second vehicle in the simulation method is moved as a function of control commands of a user. The test vehicle and the second vehicle are displayed to the user including the road, data relating to the guidance of the test vehicle being collected and stored during the simulation method. A system is also described.
