CONTROLLING ACCESS OF A VEHICLE BASED ON LOCAL CLOCK TIMINGS AND A DIGITAL KEY INTERFACE

Various systems and methods are presented regarding controlling access to a vehicle. Access of the vehicle, by a second device, can be controlled by a first device utilizing authentication keys, access duration, and/or generation of access confirmations and access revocations. Respective timing of operations can be based on one or more timings generated by a real-time clock located on the vehicle. Further, in the event of an access confirmation not being received from the first device at a defined time, access of the second vehicle can be revoked. Communications between the respective devices can utilize short-range wireless communications. Access to the vehicle can be via controlling a digital/electronic interface, which can be further connected to a smart key configured to control operation of a vehicle door, engine/motor, and suchlike. The first device and the second device can be portable/mobile devices (e.g., one or more cellphones).
