Abstract

Claims (41)

1. An apparatus comprising at least one processor and at least one non-transitory memory including computer program code instructions, the computer program code instructions configured to, when executed, cause the apparatus to:

receive a destination for a vehicle as input;

receive attribute data associated with a source capable of acquiring vehicle signature information, wherein the source is a device comprising a sensor capable of acquiring the vehicle signature information;

determine a detection range of the source based on the attribute data;

based on the detection range, select a subset from a plurality of road segments as a route from a location to the destination such that the subset is outside the detection range, wherein the subset is one or more of the plurality of road segments, and wherein each of the plurality of road segments is a road connecting two nodes; and

cause the vehicle to traverse the route or the portion thereof.

2. The apparatus of claim 1 , wherein the attribute data are sensor attribute data indicating sensor types, sensor detection range, or a combination thereof.

3. The apparatus of claim 1 , wherein the computer program code instructions, when executed, cause the apparatus to:

receive attribute data associated with the source;

determine a detection range of the source based on the attribute data; and

update a map layer to include a data point indicating a current location of the source and the detection range of the source.

4. The apparatus of claim 1 , wherein the subset is a first subset, wherein the route is a first route, and wherein the computer program code instructions, when executed, cause the apparatus to:

determine a detection avoidance period based on the attribute data, wherein the detection avoidance period indicates an amount of time that a vehicle can be within the detection range without having the vehicle signature information associated with the vehicle being acquired by the vehicle;

based on the detection avoidance period, select a second subset from the plurality of road segments as a second route from the location to the destination; and

output the second route or a portion thereof on a user interface.

5. The apparatus of claim 1 , wherein the subset is a first subset, wherein the route is a first route, and wherein the computer program code instructions, when executed, cause the apparatus to:

determine a heading of the source based on the attribute data;

based on the heading, select a second subset from the plurality of road segments as a second route from the location to the destination; and

output the second route or a portion thereof on a user interface.

6. A non-transitory computer-readable storage medium having computer program code instructions stored therein, the computer program code instructions, when executed by at least one processor, cause the at least one processor to:

receive a destination for a vehicle as input;

receive attribute data associated with a source capable of acquiring vehicle signature information, wherein the source is a device comprising a sensor capable of acquiring the vehicle signature information;

determine a detection range of the source based on the attribute data;

based on the detection range, select a subset from a plurality of road segments as a route from a location to the destination such that the subset is outside the detection range, wherein the subset is one or more of the plurality of road segments, and wherein each of the plurality of road segments is a road connecting two nodes; and

cause the vehicle to traverse the route or the portion thereof.

7. The non-transitory computer-readable storage medium of claim 6 , wherein the attribute data are sensor attribute data indicating sensor types, sensor detection range, or a combination thereof.

8. The non-transitory computer-readable storage medium of claim 6 , wherein the computer program code instructions, when executed by the at least one processor, cause the at least one processor to:

receive attribute data associated with the source;

determine a detection range of the source based on the attribute data; and

update a map layer to include a data point indicating a current location of the source and the detection range of the source.

9. A method comprising:

receiving a destination for a vehicle as input;

receiving attribute data associated with a source capable of acquiring vehicle signature information, wherein the source is a device comprising a sensor capable of acquiring the vehicle signature information;

determining a detection range of the source based on the attribute data;

based on the detection range, selecting a subset from a plurality of road segments as a route from a location to the destination such that the subset is outside the detection range, wherein the subset is one or more of the plurality of road segments, and wherein each of the plurality of road segments is a road connecting two nodes; and

causing the vehicle to traverse the route or the portion thereof.

10. The method of claim 9 , wherein the attribute data are sensor attribute data indicating sensor types, sensor detection range, or a combination thereof.

11. The method of claim 9 further comprising:

receiving attribute data associated with the source;

determining a detection range of the source based on the attribute data; and

updating a map layer to include a data point indicating a current location of the source and the detection range of the source.
