Constraint augmentation in a navigational system
First Claim
1. A navigation system for a host vehicle, the system comprising:
- at least one processing device programmed to;
identify a navigational state associated with the host vehicle;
determine a first predefined navigational constraint implicated by at least one aspect of the navigational state;
identify a presence of at least one navigational constraint augmentation factor;
determine a second navigational constraint based on identification of the at least one navigational constraint augmentation factor, wherein the second navigational constraint is different from the first navigational constraint and includes at least one characteristic augmented with respect to the first navigational constraint;
determine, based on the identified navigational state, a navigational action for the host vehicle satisfying the second navigational constraint; and
cause at least one adjustment of a navigational actuator of the host vehicle in response to the determined navigational action.

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 navigational state associated with the host vehicle; provide the navigational state to a trained navigational system; receive, from the trained navigational system, a desired navigational action for execution by the host vehicle in response to the identified navigational state; analyze the desired navigational action relative to one or more predefined navigational constraints; determine an actual navigational action for the host vehicle, wherein the actual navigational action includes at least one modification of the desired navigational action determined based on the one or more predefined navigational constraints; and cause at least one adjustment of a navigational actuator of the host vehicle in response to the determined actual navigational action for the host vehicle.
