EFFICIENT DATA FLOW ALGORITHMS FOR AUTONOMOUS LANE CHANGING, PASSING AND OVERTAKING BEHAVIORS
First Claim
1. A method for making a lane changing maneuver in an autonomously driven vehicle, said method comprising:
- providing a navigation controller on the vehicle that provides a planned route for the vehicle to follow;
providing a vehicle controller on the vehicle that receives route information from the navigation controller and provides steering, braking and throttle control for the vehicle to follow the route;
initiating a lane-change maneuver by the navigation controller to cause the vehicle to travel from a current roadway lane to an adjacent roadway lane;
initiating a lane-change maneuver by the vehicle controller to cause the vehicle to travel from the current roadway lane to an adjacent roadway lane; and
providing route information including providing a route segment from the navigation controller to the vehicle controller in response to either the navigation controller initiated lane change or the vehicle controller initiated lane change that identifies a path in the adjacent lane for the vehicle controller to steer the vehicle to make the lane-change maneuver.

Abstract
A system and method for providing lane changing maneuvers in an autonomously driven vehicle. The vehicle includes a navigation controller that provides a planned route for the vehicle to follow and a vehicle controller that receives route information from the navigation controller and provides steering, braking and throttle control for the vehicle to follow the route. Either the navigation controller or the vehicle controller may initiate a lane change maneuver to cause the vehicle to be steered from a travel lane to an adjacent lane. In response to the lane change requirement, the navigation controller provides a route segment to the vehicle controller and a lane-change zone so that the vehicle controller can steer the vehicle to the adjacent lane while in the lane-change zone.

10. A method for making a lane changing maneuver in an autonomously driven vehicle, said method comprising:
-
providing a navigation controller on the vehicle that provides a planned route for the vehicle to travel; providing a vehicle controller on the vehicle that receives route information from the navigation controller and provides steering, braking and throttle control for the vehicle to follow the route; initiating a lane-change maneuver to cause the vehicle to travel from a current roadway lane to an adjacent roadway lane; and providing route information from the navigation controller in response to initiating the lane-change maneuver that identifies a path in the adjacent lane for the vehicle controller to steer the vehicle to make the lane-change maneuver, wherein providing route information includes providing a route segment of the identified path in the adjacent lane and providing a lane-change zone that identifies an area in which the vehicle controller must steer the vehicle to make the lane-change maneuver. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A system for making a lane changing maneuver in an autonomously driven vehicle, said system comprising:
-
means for providing a navigation controller on the vehicle that is programmed to provides a planned route for the vehicle to travel; means for providing a vehicle controller on the vehicle that is programmed to receives route information from the navigation controller and to provides steering, braking and throttle control for the vehicle to follow the route; means for initiating a lane-change maneuver to cause the vehicle to travel from a current roadway lane to an adjacent roadway lane; and means for providing route information from the navigation controller in response to initiating the lane-change maneuver that identifies a path in the adjacent lane for the vehicle controller to steer the vehicle to make the lane-change maneuver, wherein the means for providing route information also provides a route segment of the identified path in the adjacent lane and providing a lane-change zone that identifies an area in which the vehicle controller must steer the vehicle to make the lane-change maneuver. - View Dependent Claims (20)
