Abstract: A vehicle sharing system includes: a shared vehicle including: a passenger cabin including seats; antennas; and a module configured to, via the antennas, determine a present location of a key of the shared vehicle; and a server that is remote from the shared vehicle and that is configured to, in response to a request to end a period of use of the shared vehicle: determine whether the key is inside the passenger cabin; and determine whether to end the period of use of the shared vehicle and charge a payment account associated with a user for the period of use based on whether the key is inside of the passenger cabin.

Abstract: A lock control system includes: an automatic door lock configured to unlock and lock a door of a vehicle; a wireless transceiver configured to wirelessly receive a first unique identifier for a period of use of the vehicle by a non-owner of the vehicle from a server that is remote from the vehicle; an input device configured to capture a second unique identifier output by an electronic device through a glass component of the vehicle; and a lock control module configured to: compare the first unique identifier with the second unique identifier; and selectively actuate the automatic door lock thereby unlocking the door in response to a determination that the second unique identifier is the same as the first unique identifier.

Abstract: A location system of a shared vehicle includes: a location module configured to, when a signal strength of a global position system (GPS) module is less than a predetermined signal strength, determine a present location of the shared vehicle within a parking structure based on measurements from one or more sensors of the shared vehicle; a floor module configured to, when the signal strength of the GPS module is less than the predetermined signal strength, determine a present floor of the parking structure on which the shared vehicle is located; and a wireless transceiver module configured to, when the shared vehicle is off and parked within the parking structure, transmit the present location and the present floor to a rental server that is remote from the shared vehicle.
