Abstract: A semi-public blockchain maintained on one or more nodes in a map cloud platform comprises data for maintaining a global map of a predetermined geographic area. The blockchain also comprises a plurality of data records, where each data record is associated with an update to a global map. When a message associated with a map update to the global map is received, the nodes of the blockchain determine a consensus by evaluating the map update, where the evaluating comprises performing a plurality of proofs including a proof of location, a proof of iterations, a proof of physical delivery and a proof of safety. When consensus is attained and the map update is validated, a data record associated with the map update is generated and added to the blockchain with a timestamp and a link to prior data records in the blockchain.

Abstract: In various examples, searching of data—including real-world data, simulation data, system under test (SUT) data, and/or map data—may be executed using a query engine configured to compile detailed binary code from high-level declarative queries for searching the data to identify scenarios or engineering artifacts of interest. A user may identify a behavior or scenario of interest, define the behavior or scenario in a descriptive and/or declarative manner—including implicit indications of temporal or spatial relationships—and the query engine may then compile an explicit procedural description that may be used to search the data for one or more instances and/or variations of the defined scenario or computational representation of an engineering artifact under investigation. Once the scenarios are identified, behaviors of the machine may be observed, criteria with respect to the machine performance may be evaluated, and/or test coverage with respect to the scenario type may be collected.

Abstract: In various examples, scenarios may be defined using a declarative description—e.g., defining a behavior of interest—that the present system may convert into a procedural description for generating one or more instances and/or variations of a scenario for testing an autonomous or semi-autonomous machine in a virtual environment. The system may execute observers or evaluators for testing the performance and accuracy of the machine and may compute coverage of various elements based on the generated virtual scenarios, and may feed the results back to the system to generate additional instances and/or variations where the coverage or accuracy is below a desired level. As a result, the system may include an end-to-end framework for generating scenarios in virtual environments, testing and validating the scenarios themselves, and/or testing and validating the underlying autonomous or semi-autonomous systems of the machine—all based on a declarative description.
