Abstract

A sensor control system for a vehicle includes one or more processors and a memory communicably coupled to the one or more processors. The memory stores a zone of interest determination module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to determine if at least one localized zone of interest resides within a preliminary zone of interest of the vehicle. The memory also stores a sensor control module including computer-readable instructions that when executed by the one or more processors cause the one or more processors to control one or more operational parameters of at least one sensor so as to, if at least one localized zone of interest resides within the preliminary zone of interest, bring at least a portion of the at least one localized zone of interest into a of field view of the at least one sensor.

7. The sensor control system of claim 1 wherein the at least one sensor is a supplemental sensor of the vehicle.

8. The sensor control system of claim 1 wherein the zone of interest determination module includes computer-readable instructions that when executed by the one or more processors cause the one or more processors to:

determine the localized zone of interest responsive to traffic condition information; and

add the localized zone of interest to a digital map.

9. The sensor control system of claim 1 wherein the zone of interest determination module includes computer-readable instructions that when executed by the one or more processors cause the one or more processors to:

determine the localized zone of interest responsive to road geometry information; and

add the localized zone of interest to a digital map.

10. The sensor control system of claim 1 wherein the sensor control module includes computer-readable instructions that when executed by the one or more processors cause the one or more processors to continuously control the one or more operational parameters of the at least one available remote sensor as the connectibly-configured other ground vehicle on which the at least one available remote sensor is mounted moves, so as to maintain at least a portion of the at least one localized zone of interest in the field of view of the at least one available remote sensor until the at least one available remote sensor can no longer be controlled so as to bring at least a portion of the at least one localized zone of interest into the field of view of the at least one available remote sensor.

11. A vehicle including the sensor control system of if claim 1 .

12. The sensor control system of claim 1 wherein the at least one available remote sensor is a supplemental sensor of the connectibly-configured other ground vehicle.

13.
