Abstract

A lane management system for operating an automated vehicle includes a navigation-device, a vehicle-detector, and a controller suitable for use on a host-vehicle. The navigation-device is used to determine a preferred-route to a destination of the host-vehicle. The vehicle-detector is used to determine a relative-location of an other-vehicle proximate to the host-vehicle. The controller is in communication with the navigation-device and the vehicle-detector. The controller is configured to determine an alternate-route when the relative-location is such that a preferred-lane of the preferred-route is obstructed whereby the host-vehicle is unable to follow the preferred-route. Alternatively, the controller is configured to determine an initiate-time to perform a lane-change necessary to maneuver the host-vehicle into a preferred-lane of the preferred-route so the host-vehicle can follow the preferred-route, wherein the initiate-time is determined based on the relative-location.

Claims

1. A lane management system for operating an automated vehicle, said system comprising:

a navigation-device suitable for use on a host-vehicle, said navigation-device used to determine a preferred-route to a destination of the host-vehicle;

a vehicle-detector suitable for use on the host-vehicle, said vehicle-detector used to determine a relative-location of an other-vehicle proximate to the host-vehicle; and

a controller in communication with the navigation-device and the vehicle-detector, said controller configured to determine an alternate-route when the relative-location is such that a preferred-lane of the preferred-route is obstructed whereby the host-vehicle is unable to follow the preferred-route.

2. The system in accordance with claim 1, wherein the controller is further configured to determine an initiate-time to perform a lane-change necessary to maneuver the host-vehicle into the preferred-lane so the host-vehicle can follow the preferred-route, wherein the initiate-time is determined based on the relative-location.

3. The system in accordance with claim 2, wherein the controller is further configured to determine a traffic-density based on how many other-vehicles are present in the preferred-lane, and further determine the initiate-time based on the traffic-density.

4. The system in accordance with claim 2, wherein the controller is further configured to determine a speed of other-vehicles present in the preferred-lane, and further determine the initiate-time based on the speed.

5. The system in accordance with claim 2, wherein the controller is further configured to determine a lane-count of lanes that must be crossed to reach the preferred-lane, and further determine the initiate-time based on the lane-count.

6. A lane management system for operating an automated vehicle, said system comprising:

a navigation-device suitable for use on a host-vehicle, said navigation-device used to determine a preferred-route to a destination of the host-vehicle;

a vehicle-detector suitable for use on the host-vehicle, said vehicle-detector used to determine a relative-location of an other-vehicle proximate to the host-vehicle; and

a controller in communication with the navigation-device and the vehicle-detector, said controller configured to determine an initiate-time to perform a lane-change necessary to maneuver the host-vehicle into a preferred-lane of the preferred-route so the host-vehicle can follow the preferred-route, wherein the initiate-time is determined based on the relative-location.

7. The system in accordance with claim 6, wherein the controller is further configured to determine a traffic-density based on how many other-vehicles are present in the preferred-lane, and further determine the initiate-time based on the traffic-density.

8. The system in accordance with claim 7, wherein navigation-device is used to detect a traffic-signal, and the controller is further configured to determine a signal-distance from the host-vehicle to the traffic-signal, and further determine the initiate-time based on the signal-distance.

9. The system in accordance with claim 6, wherein the controller is further configured to determine a speed of other-vehicles present in the preferred-lane, and further determine the initiate-time based on the speed.

10. The system in accordance with claim 6, wherein the controller is further configured to determine an alternate-route when the relative-location obstructs the preferred-lane such that the host-vehicle is unable to follow the preferred-route.

11. The system in accordance with claim 6, wherein the controller is further configured to determine a lane-count of lanes that must be crossed to reach the preferred-lane, and further determine the initiate-time based on the lane-count.
