Remote vehicle motive control with optimized mobile device localization

A system for a vehicle, comprising:

• a processor;
• a low-energy communication protocol disposed in communication with the processor;
• and
• a memory for storing executable instructions, the processor configured to execute instructions to perform a selective mobile device localization for a mobile device, the instructions causing the processor to:
• establish a high-fidelity zone;
• determine a first geographic position of the mobile device with respect to the vehicle at a first time via a high-fidelity Phone-as-a-Key (PaaK) localization system disposed with a vehicle controller of the vehicle;
• responsive to the successful determination of the first geographic position of the mobile device, switch to a low-fidelity radio frequency module for tracking changes in geographic position of the mobile device;
• determine a second geographic position of the mobile device at a second time after the first time via the low-fidelity radio frequency module, wherein the second geographic position is outside of the high-fidelity zone;
• and
• reduce, based on the second geographic position indicating that the mobile device is outside of the high-fidelity zone, a motive functionality of the vehicle from a first motive mode having a full motive functionality to a second motive mode having a reduced motive functionality responsive to determining that the mobile device is not present in the high-fidelity zone, wherein the reduced motive functionality reduces one or more mobility capabilities of the vehicle relative to the full motive functionality.

A non-transitory computer-readable storage medium in a vehicle control module, the storage medium having instructions stored thereupon which, when executed by the vehicle control module, cause the vehicle control module to:

• establish a high-fidelity zone;
• determine a first geographic position of a mobile device with respect to the vehicle at a first time via a high-fidelity Phone-as-a-Key (PaaK) localization system disposed within a vehicle controller of the vehicle;
• responsive to the successful determination of the first geographic position of the mobile device, switch to a low-fidelity radio frequency module for tracking changes in geographic position of the mobile device;
• determine a second geographic position of the mobile device at a second time after the first time via the low-fidelity radio frequency module, wherein the second geographic position is outside of the high-fidelity zone;
• and
• determine a change in the geographic position of the mobile device using a low-fidelity radio frequency module comprising a single antenna;
• and
• reduce, based on the second geographic position indicating that the mobile device is outside of the high-fidelity zone, a motive functionality of the vehicle from a first motive mode having a full motive functionality to a second motive mode having a reduced motive functionality responsive to determining that the mobile device is not present in the high-fidelity zone, wherein the reduced motive functionality reduces one or more mobility capabilities of the vehicle relative to the full motive functionality.
