Abstract: In various examples, systems and methods are disclosed that perform sensor fusion using rule-based and learned processing methods to take advantage of the accuracy of learned approaches and the decomposition benefits of rule-based approaches for satisfying higher levels of safety requirements. For example, in-parallel and/or in-serial combinations of early rule-based sensor fusion, late rule-based sensor fusion, early learned sensor fusion, or late learned sensor fusion may be used to solve various safety goals associated with various required safety levels at a high level of accuracy and precision. In embodiments, learned sensor fusion may be used to make more conservative decisions than the rule-based sensor fusion (as determined using, e.g., severity (S), exposure (E), and controllability (C) (SEC) associated with a current safety goal), but the rule-based sensor fusion may be relied upon where the learned sensor fusion decision may be less conservative than the corresponding rule-based sensor fusion.

Abstract: An architecture can generate lane graphs or path determinations, for devices such as robots or autonomous vehicles, using multiple sources of data while satisfying applicable requirements and regulations for operation. A system can fuse together data from multiple sources useful to determine localization. To ensure safety compliance, this fused data is compared against data from systems where safety is trusted and, as long as at least two comparators agree with the fused localization data, the fused localization data can be used and verified to be safety regulation compliant. This system can also fuse together available information useful for lane perception. This fused data is compared against data from systems where the safety is trusted, and as long as at least two comparators for these safety-compliant systems agree with the fused lane graph data, then the fused lane graph data can be provided for navigation and verified to be regulation compliant.
