Systems and methods to compensate for wireless signal attenuation in a passive key hands-free vehicle-related application

A non-transitory computer-readable medium storing computer-executable instructions, that when executed by a processor, cause the processor to perform operations of:

• determining, at a first instant in time, a first separation distance between a mobile device and a wearable device;
• determining, at a second instant in time, a second separation distance between the mobile device and the wearable device;
• evaluating the first separation distance and the second separation distance to determine a location of the mobile device relative to an individual, the location including at least one of:
• a front portion of the individual or a rear portion of the individual;
• and
• executing a wireless signal procedure to calculate a distance between the mobile device and a vehicle, wherein calculating comprises compensating for a wireless signal attenuation that is attributable to the location of the mobile device.

A system comprising:

• a mobile device configured to execute passive key hands-free operations;
• a passive key hands-free management system in a vehicle, the passive key hands-free management system comprising:
• a first memory that stores computer-executable instructions;
• and
• a first processor configured to access the first memory and execute the computer-executable instructions to at least:
• determine, at a first instant in time, a first separation distance between a mobile device and a wearable device;
• determine, at a second instant in time, a second separation distance between the mobile device and the wearable device;
• evaluate the first separation distance and the second separation distance to determine a location of the mobile device relative to an individual, the location including at least one of:
• a front portion of the individual or a rear portion of the individual;
• and
• apply a compensating factor to an amplitude of a first wireless signal, the compensating factor based on a wireless signal attenuation characteristic attributable to the location of the mobile device relative to the individual.
