  • Patent number: 12339127
    Abstract: Various examples are directed to systems and methods for generating improved autonomous vehicle (AV) navigation route data and estimated time of arrival (ETA) data. A system may receive delivery data from an AV delivering a passenger or product, where the delivery data includes a delivery origin, a delivery destination, and an ETA and navigation route generated by the AV. The AV may have accurate short-term information, such as the next few navigation maneuvers planned by the AV. The system may be able to provide more accurate longer-term information, such as generating an overall calculated route and calculated completion time based a current location and the delivery destination. The system may receive updated short-term information and combine this information with the calculated route and calculated completion to generate a more accurate set of route data and ETA data.

  • Patent number: 11724714
    Abstract: Systems and methods for autonomous vehicle state management are provided. An offboard state service can obtain a vehicle command associated with changing an onboard-defined state of an autonomous vehicle. Data indicative of the command can be provided to a computing system onboard the autonomous vehicle. The onboard computing system can initiate a vehicle action in accordance with the command and provide a command response indicative of an updated vehicle status for the onboard-defined state to the state service. In response, the state service can update a current status for the onboard-defined state as represented by a vehicle profile corresponding to the autonomous vehicle. The state service can generate an update event indicative of the vehicle state and the updated current status and publish the update event to a distributed event stream such that a number of devices subscribed to the event stream can receive data indicative of the update event.
