Classification: CPC G  B | IPC B  G

Claim 11:
12. A non-transitory computer-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:
obtaining a first global positioning system (GPS) trace from a first trip along a first route, wherein the first route comprises first route segments represented by first respective edges in a navigation map, wherein the first GPS trace comprises first coordinates along the first route and first trace metadata, wherein the first trace metadata comprises first hybrid-related aspects of a hybrid electric vehicle (HEV) recorded at at least some of the first coordinates, and wherein the first hybrid-related aspects comprise first respective average battery consumption/regeneration (eabcr) and first battery regeneration on stop (eabrs) for the first respective edges;
obtaining a second GPS trace from a second trip along a second route that at least partially overlaps the first route, wherein the second route comprises second route segments represented by second respective edges in the navigation map, wherein the second GPS trace comprises second coordinates along the second route and second trace metadata, wherein the second trace metadata comprises second hybrid-related aspects of the HEV recorded at at least some of the second coordinates, and wherein the second hybrid-related aspects comprise second respective average battery consumption/regeneration (eabcr) and second battery regeneration on stop (eabrs) for the first respective edges;
updating the navigation map to incorporate an aggregation of the first trace metadata and the second trace metadata for each edge of edges of the navigation map corresponding to route segments traversed along the first route or along the second route; and
using, after updating the navigation map, the navigation map to obtain an activation action of an engine of the HEV, wherein the activation action is selected from a set comprising a first activation action of turning the engine on and a second activation action of turning the engine off, and the first activation action causes the engine to turn on to charge a battery of the HEV wherein the activation action is obtained using a policy that is configured to map states of the HEV to activation actions, wherein a state of the HEV is determined based on a set of edges of the navigation map probabilistically determined to have been traversed, a current battery level of the HEV, and a current status of the engine of the HEV, wherein the current status of the engine is one of an ON state or an OFF state.
