Efficient tracking of personal device locations

A system comprising:

• an in-vehicle component, associated with a zone seating position of a vehicle, programmed to
• acquire wireless signal strength intensity information of a personal device from other in-vehicle components;
• identify zones of the other in-vehicle components, each zone including a plurality of in-vehicle components;
• for each of the zones, calculate an average signal strength of the personal device to the in-vehicle components in the zone;
• and
• associate the personal device with the zone having a highest average signal strength to the personal device.

A computer-implemented method comprising:

• detecting user interaction to an in-vehicle component of a zone;
• acquiring signal strength intensity information of personal devices from other in-vehicle components of the zone;
• calculating average signal strengths of the personal devices to the in-vehicle components;
• associating one of the personal devices to the zone as having a highest average signal strength to the in-vehicle components of the zone;
• and
• sending a notification to the one of the personal devices.

A system comprising:

• a memory;
• and
• a processor programmed to:
• for each seating zone of a vehicle, identify a plurality of in-vehicle components associated with the zone and average signal strength between the personal device and the plurality of in-vehicle components of the zone,
• identify for which zone the average signal strength is highest, and
• receive a notification responsive to a user interaction detected by one of the in-vehicle components of the zone.
