Process and system for sensor sharing for an autonomous lane change

1. A process for sensor sharing for an autonomous lane change, comprising:

within a dynamic controller of a host vehicle operating in a first lane of travel of a roadway, monitoring sensors of the host vehicle;

establishing communication between the host vehicle and a confederate vehicle on the roadway;

monitoring sensors of the confederate vehicle including one of a camera device, a radar device, or a light detection and ranging (LIDAR) device;

within the dynamic controller of the host vehicle, utilizing a combination of data from the sensors of the host vehicle and data from the sensors of the confederate vehicle to establish absence of an additional vehicle in a second lane of travel next to the host vehicle and initiate a lane change maneuver for the host vehicle based upon the established absence of the additional vehicle; and

executing the lane change maneuver for the host vehicle.

2. The process of claim 1 , wherein establishing the communication between the host vehicle and the confederate vehicle comprises establishing direct vehicle to vehicle communication.

3. The process of claim 1 , wherein establishing the communication between the host vehicle and the confederate vehicle comprises communicating through a wireless network.

4. The process of claim 1 , wherein utilizing the combination of the data from the sensors of the host vehicle and the data from the sensors of the confederate vehicle to establish absence of the additional vehicle in the second lane of travel next to the host vehicle comprises:

selecting a calculated perception range to initiate the lane change maneuver; and

determining whether an effective sensor range of the sensors of the host vehicle and an effective sensor range of the sensors of the confederate vehicle together cover the calculated perception range.

5. The process of claim 4 , wherein determining whether the effective sensor range of the sensors of the host vehicle and the effective sensor range of the sensors of the confederate vehicle together cover the calculated perception range comprises determining an effect of a third vehicle obscuring the sensors of the host vehicle by limiting a portion of a field of view of the sensors of the host vehicle.

6. The process of claim 5 , wherein determining whether the effective sensor range of the sensors of the host vehicle and the effective sensor range of the sensors of the confederate vehicle together cover the calculated perception range further comprises determining an effect of the third vehicle obscuring the sensors of the confederate vehicle.

7. The process of claim 4 , wherein determining whether the effective sensor range of the sensors of the host vehicle and the effective sensor range of the sensors of the confederate vehicle together cover the calculated perception range comprises determining an effect of a trailer being towed by the host vehicle obscuring the sensors of the host vehicle by limiting a portion of a field of view of the sensors of the host vehicle.

8. The process of claim 4 , wherein selecting the calculated perception range to initiate the lane change maneuver comprises determining a time to achieve a target speed at a completion of the lane change maneuver.

9. The process of claim 4 , wherein selecting the calculated perception range comprises adding an offset value.

10. A process for sensor sharing for an autonomous lane change, comprising:

within a dynamic controller of a host vehicle, monitoring sensors of the host vehicle upon a roadway;

establishing communication between the host vehicle and a confederate vehicle on the roadway;

monitoring sensors of the confederate vehicle;

within the dynamic controller of the host vehicle, utilizing data from the sensors of the host vehicle and data from the sensors of the confederate vehicle to initiate a lane change maneuver for the host vehicle; and

executing the lane change maneuver for the host vehicle;

wherein utilizing the data from the sensors of the host vehicle and the data from the sensors of the confederate vehicle to initiate the lane change maneuver for the host vehicle comprises:

comparing an absolute value of an initial speed of the host vehicle minus a determination lane speed limit plus an offset value to a calibration value; and

declining to initiate the lane change maneuver based upon the comparing.

11. The process of claim 1 ,

wherein executing the lane change maneuver for the host vehicle comprises moving the host vehicle into the second lane of travel.

12. The process of claim 1 , wherein monitoring the sensors of the host vehicle comprises detecting an oversized vehicle upon the roadway;

wherein the host vehicle is initially traveling in the first lane of travel; and

wherein executing the lane change maneuver for the host vehicle comprises moving the host vehicle to one side of the first lane of travel based upon maintaining an offset from the oversized vehicle.

13. The process of claim 12 , further comprising determining an effect of a trailer being towed by the host vehicle obscuring the sensors of the host vehicle by limiting a portion of a field of view of the sensors of the host vehicle.

14. The process of claim 1 , wherein the confederate vehicle is rearward of the host vehicle.

15. The process of claim 1 , wherein the confederate vehicle is forward of the host vehicle.

16. A system for sensor sharing for an autonomous lane change, comprising:

a host vehicle traveling upon a first lane of travel of a roadway and including a first sensor configured to monitor the roadway;

a confederate vehicle traveling upon the roadway including a second sensor configured to monitor the roadway, wherein the second sensor includes one of a camera device, a radar device, or a light detection and ranging (LIDAR) device;

a communication link between the host vehicle and the confederate vehicle; and

a computerized dynamic controller within the host vehicle, programmed to:

monitor data from the first sensor;

monitor data from the second sensor through the communication link;

utilize a combination of the data from the first sensor and the data from the second sensor to establish absence of an additional vehicle in a second lane of travel next to the host vehicle and to initiate a lane change maneuver for the host vehicle based upon the established absence of the additional vehicle; and

authorize the lane change maneuver for the host vehicle.

17. The system of claim 16 , wherein the host vehicle comprises a towed trailer; and

wherein the computerized dynamic controller evaluates an effect of the towed trailer upon the data from the first sensor.

18. The system of claim 16 , wherein the dynamic controller programmed to utilize the combination of the data from the first sensor and the data from the second sensor to initiate the lane change maneuver for the host vehicle comprises:

selecting a calculated perception range to initiate the lane change maneuver; and

determining whether an effective sensor range of the sensors of the host vehicle and an effective sensor range of the sensors of the confederate vehicle together cover the calculated perception range.
