Abstract

At least first and second geofences are established. The first geofence provides for indicating to an operator of a vehicle a limit to the territorial extent of a permitted operational area for the vehicle. The second geofence limits the territorial extent of a permitted operational area for the mobile platform, typically by limiting the mobility of the mobile platform. The first and second geofences are located with respect to one another and the permitted operational area so that with movement through the limits of the permitted operational area, the mobile platform encounters the first geofence no later than it encounters the second geofence.

Claims

1. A method of controlling geofences for a mobile platform, the method comprising the steps of:

establishing at least a first geofence for indicating a limit in territorial extent of a permitted operational area for a mobile platform;

establishing a second geofence for limiting the territorial extent of a permitted operational area for the mobile platform; and

locating the first and second geofences relative to the permitted operational area so that with movement of the mobile platform through the limits of the permitted operational area from the permitted operational area, the mobile platform encounters the first geofence no later than it encounters the second geofence and the first and second geofences are not fully coincident.

2. A method in accordance with claim 1, wherein the permitted operational area surrounds the first and second geofences.

3. A method in accordance with claim 1, wherein the first geofence circumscribes the permitted operational area.

4. A method in accordance with claim 2, the method comprising the further steps of:

selecting differentiated sets of responses for the first and second geofences.

5. A method in accordance with claim 3, the method comprising the further steps of:

selecting differentiated sets of responses for the first and second geofences.

6. A geofence system comprising:

a vehicle;

a source of position information for the vehicle;

a vehicle control system including data processing facilities having access to the position information, the vehicle control system including facilities for issuing warnings to drivers and for inhibiting vehicle operation;

a program executable on the data processing facilities and responsive to the position information for causing the vehicle control system to issue warnings to a vehicle driver or to inhibit aspects of vehicle operation; and

the program providing first and second tiers of responses affecting vehicle operation relative to its normal operation, the first and second tiers of responses being selected from possible warnings and aspects of vehicle operation subject to inhibition, the first tier of responses occurring at some locations exclusive of the locations producing the second tier of responses.

7. A geofence system in accordance with claim 6, further comprising:

the locations corresponding to first tier responses and exclusive of the locations producing the second tier responses being contiguous and having a boundary defining a first geofence; and

the remaining locations corresponding to second tier responses being contiguous, spaced from the first geofence and separated from the locations of normal operation.

8. A geofence system in accordance with claim 7, further comprising:

the first geofence bounding the locations of normal operation.

9. A geofence system in accordance with claim 7, further comprising:

the first geofence being bounded by the locations of normal operation.
