Claim 18:
19. A computer comprising a processor and a memory, the memory storing instructions executable to:
determine a currently activatable feature on a vehicle from a plurality of features;
select a search strategy from a plurality of search strategies based on the currently activatable feature;
upon selecting a first strategy as the search strategy, during a search iteration, determine distance data to at least one mobile device from a first subset of a plurality of Ultra-Wideband (UWB) anchors of the vehicle, and inhibit a remainder of the UWB anchors other than the first subset, wherein the first strategy defines the first subset;
perform a trilateral calculation on the distance data for the at least one mobile device; and
actuate a component of the vehicle according to the currently activatable feature based on a result of the trilateral calculation;
wherein the first strategy is one of (1) defines the first subset to have a number of the UWB anchors equal to one, (2) defines a first sub-subset of the first subset to determine the distance data from a first mobile device of the at least one mobile device and a second sub-subset of the first subset to determine the distance data from a second mobile device of the at least one mobile device, or (3) during a next search iteration, deselects at least one of the UWB anchors from the first subset.
