Abstract
A first distinct vehicle operational scenario is identified for an autonomous vehicle (AV). A first set of candidate vehicle control actions are received from a model that provides a first solution to the first distinct vehicle operational scenario. An action is selected from the first set of candidate vehicle control actions. The AV is controlled based on the action. The first solution is obtained offline in a first idealized situation that is decoupled from a current context of the AV.
Claims20
A method for use in traversing a vehicle transportation network by an autonomous vehicle (AV), the method comprising:
- identifying a first distinct vehicle operational scenario for the AV;
- receiving, from a model that provides a first solution to the first distinct vehicle operational scenario, a first set of candidate vehicle control actions,
- wherein the first solution is obtained offline in a first idealized situation that is decoupled from a current context of the AV;
- selecting an action from the first set of candidate vehicle control actions;
- and controlling the AV based on the action.
An autonomous vehicle, comprising:
- a processor configured to execute instructions stored on a non-transitory computer readable medium to:
- identify a first distinct vehicle operational scenario for the autonomous vehicle;
- receive, from a model that provides a first solution to the first distinct vehicle operational scenario, a first set of candidate vehicle control actions,
- wherein the first solution is obtained offline in a first idealized situation that is decoupled from a current context of the autonomous vehicle;
- select an action from the first set of candidate vehicle control actions;
- and
- control the autonomous vehicle based on the action.
A non-transitory computer readable medium storing instructions operable to cause one or more processors to perform operations, comprising:
- identifying a first distinct vehicle operational scenario for an autonomous vehicle (AV);
- receiving, from a model that provides a first solution to the first distinct vehicle operational scenario, a first set of candidate vehicle control actions,
- wherein the first solution is obtained offline in a first idealized situation that is decoupled from a current context of the AV;
- selecting an action from the first set of candidate vehicle control actions;
- and
- controlling the AV based on the action.
