1. An apparatus for managing a sensor in a computer-assisted or autonomous driving (CA/AD) vehicle, comprising:
- a sensor analyzer to determine a difference between a baseline reading and a subsequent reading of a landmark by the sensor, the baseline reading having been recorded at a first point in time when the sensor first detects the landmark; and
the subsequent reading having been recorded at a second subsequent point in time when the sensor again detects the landmark; and
a sensor manager coupled to the sensor analyzer to determine whether a management action is needed for the sensor based at least in part on the determined difference between the baseline and subsequent readings experienced for a time period length defined by the first and second points of time, in view of other differential experiences for other time period lengths reported by other similar sensors on other CA/AD vehicles,wherein, when it is determined that a management action is needed, the sensor manager is to either execute the management action or notify a user to take the management action.

Abstract
An apparatus for sensor management in computer-assisted or autonomous driving (CA/AD) vehicles, comprising a sensor analyzer and a sensor manager. The sensor analyzer is to determine a difference between a baseline sensor reading of a landmark, and a subsequent reading of the same landmark at a later point in time. The sensor manager is to determine whether a management action is needed on the basis of the determined difference, in further consideration of differential experiences from other CA/AD vehicles.

14. A method for managing a sensor in a computer-assisted or autonomous driving (CA/AD) vehicle, comprising:
-
recording a baseline reading of a landmark of the sensor of the CA/AD vehicle at a first point in time when the sensor first detects the landmark; recording a subsequent reading of the landmark of the same sensor at a second subsequent point in time when the sensor again detects the landmark; determining whether a management action is needed for the sensor based at least in part on a difference between the baseline and subsequent readings experienced for a time period length defined by the first and second points of time, in view of other differential experiences for other time period lengths reported by other similar sensors on other CA/AD vehicles; and when it is determined that a management action is needed, either executing the management action or notifying a user to take the management action. - View Dependent Claims (15, 16, 17)

18. A non-transitory computer-readable medium (CRM) comprising instructions to cause a sensor management apparatus for a computer-assisted or autonomous driving (CA/AD) vehicle, in response to execution of the instructions by a processor, to:
-
record a baseline reading of a landmark of a sensor of the CA/AD vehicle at a first point in time when the sensor first detects the landmark; record a subsequent reading of the landmark of the same sensor at a second subsequent point in time when the CA/AD vehicle again detects the landmark; determine whether a management action is needed for the sensor based at least in part on a difference between the baseline and subsequent readings experienced for a time period length defined by the first and second points of time, in view of other differential experiences for other time period lengths reported by other similar sensors on other CA/AD vehicles; and when it is determined that a management action is needed, either execute the management action or notify a user to take the management action. - View Dependent Claims (19, 20, 21)

22. A manager for a sensor in a computer-assisted or autonomous driving (CA/AD) vehicle, comprising:
-
means for recording a baseline reading of a landmark from the sensor of the CA/AD vehicle at a first point in time when the sensor first detects the landmark, and a subsequent reading of the landmark from the same sensor at a second subsequent point in time when the sensor again detects the landmark; and means for determining whether a management action is needed for the sensor based at least in part on a difference between the baseline and subsequent readings experienced for a time period length defined by the first and second points of time, in view of other differential experiences for other time period lengths reported by other similar sensors on other CA/AD vehicles; wherein, when it is determined that a management action is needed, the means for determining is to either execute the management action or notify a user to take the management action. - View Dependent Claims (23, 24, 25)
