    Abstract: The present disclosure relates to navigational systems for vehicles. In one implementation, such a navigational system may receive a first output from a first sensor and a second output from a second sensor; identify a target object in the first output; determine whether the target object is included in the second output; and determine a detected driving condition associated with the target object and whether the condition triggers a navigational constraint. If the navigational constraint is not triggered, the system may cause a first navigational adjustment if the target object is included in both the first output and the second output, and may forego any navigational adjustments if the target object is included in the first output but not in the second output. If the navigational constraint is triggered and the target object is included either in the first or second output, the system may cause a second navigational adjustment.

    Abstract: Systems and methods are provided for navigating an autonomous vehicle using reinforcement learning techniques. In one implementation, a navigation system for a host vehicle may include at least one processing device programmed to: receive, from a camera, a plurality of images representative of an environment of the host vehicle; analyze the plurality of images to identify a present navigational state associated with the host vehicle; determine a first potential navigational action for the host vehicle based on the identified present navigational state; determine a first indicator of an expected reward based on the first potential navigational action and the identified present navigational state; predict a first future navigational state based on the first potential navigational action; determine a second indicator of an expected reward associated with at least one future action determined to be available to the host vehicle in response to the first future navigational state; determine a second potential navigational action for the host vehicle based on the identified present navigational state; determine a third indicator of an expected reward based on the second potential navigational action and the identified present navigational state; predict a second future navigational state based on the second potential navigational action; determine a fourth indicator of an expected reward associated with at least one future action determined to be available to the host vehicle in response to the second future navigational state; select the second potential navigational action based on a determination that, while the expected reward associated with the first indicator is greater than the expected reward associated with the third indicator, the expected reward associated with the fourth indicator is greater than the expected reward associated with the first indicator; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the selected second potential navigational action.

    Abstract: The present disclosure relates to a navigation system for a host vehicle. The system may include a processing device programmed to receive, from a camera, a plurality of images representative of an environment of the host vehicle; analyze the plurality of images to identify at least one pedestrian in the environment of the host vehicle; cause at least one adjustment of a navigational system of the host vehicle to signal to the pedestrian a navigational intent of the host vehicle; analyze the plurality of images to detect a potential reaction of the pedestrian to the at least one adjustment of the navigational system of the host vehicle; determine a navigational action for the host vehicle based on a detected potential reaction of the pedestrian; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the determined navigational action for the host vehicle.
