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. ## Claims ### Claim 1 A location system of a shared vehicle, comprising: a location module configured to, when a signal strength of a global position system

vehicle is located; a wireless transceiver module configured to, when the shared vehicle is off and parked within the parking structure, when a second signal strength of a cellular transceiver module of the shared vehicle is less than a second predetermined signal strength, transmit the present location and the present floor to a first computing device of a first renter at an end of a first rental of the first renter of the shared vehicle; the first computing device, wherein the first computing device is configured to transmit the present location and the present floor to a rental server that is remote from the shared vehicle; and the rental server, wherein the rental server is configured to transmit the present location and the present floor of the shared vehicle to a second computing device of a second renter of the shared vehicle for a second rental of the shared vehicle after the first rental, wherein the second computing device is different than the first computing device. ### Claim 2 (depends on 1) The location system of claim 1 wherein the location module is configured to determine the present location of the shared vehicle based on a speed of the shared vehicle and a steering wheel angle of the shared vehicle. ### Claim 3 (depends on 1) The location system of claim 1 wherein the floor module is configured to selectively one of increment and decrement the present floor based on one of a longitudinal tilt and a longitudinal acceleration of the shared vehicle. ### Claim 4 (depends on 3) The location system of claim 3 wherein the floor module is configured to selectively one of increment and decrement the present floor when the one of the longitudinal tilt and the longitudinal acceleration is greater than one of a predetermined tilt and a predetermined acceleration continuously for a predetermined period. ### Claim 5 (depends on 4) The location system of claim 4 wherein the floor module is configured to increment the present floor when the one of the longitudinal tilt and the longitudinal acceleration in a rearward direction of the shared vehicle is greater than the one of the predetermined tilt and the predetermined acceleration continuously for the predetermined period. ### Claim 6 (depends on 4) The location system of claim 4 wherein the floor module is configured to decrement the present floor when the one of the longitudinal tilt and the longitudinal acceleration in a forward direction of the shared vehicle is greater than the one of the predetermined tilt and the predetermined acceleration continuously for the predetermined period. ### Claim 7 (depends on 1) The location system of claim 1 further comprising a parking structure module configured to indicate whether the shared vehicle is within a parking structure based on a second present location of the shared vehicle determined by the GPS module of the shared vehicle, wherein the floor module and the location module are configured to determine the present floor and the present location, respectively, in response to an indication from the parking structure module that the shared vehicle is within a parking structure. ### Claim 8 (depends on 7) The location system of claim 7 wherein the parking structure module is configured to indicate that the shared vehicle is within a parking structure when the second present location is within boundaries of a parking structure stored in a parking structure database. ### Claim 9 (depends on 7) The location system of claim 7 wherein the parking structure module is configured to indicate that the shared vehicle is not within a parking structure when the second present location is not within boundaries of any parking structure stored in a parking structure database. ### Claim 10 (depends on 1) The location system of claim 1 further comprising a parking structure module configured to indicate whether the shared vehicle is within a parking structure based on an ambient light intensity and the signal strength of the GPS module, wherein the floor module and the location module are configured to determine the present floor and the present location, respectively, in response to an indication from the parking structure module that the shared vehicle is within a parking structure. ### Claim 11 (depends on 10) The location system of claim 10 wherein the parking structure module is configured to indicate that the shared vehicle is within a parking structure when the signal strength is less than the predetermined signal strength and the ambient light intensity is less than a predetermined intensity. ### Claim 12 (depends on 10) The location system of claim 10 wherein the parking structure module is configured to indicate that the shared vehicle is within not a parking structure when at least one of (a) the signal strength is not less than the predetermined signal strength and (b) the ambient light intensity is not less than a predetermined intensity. ### Claim 13 (depends on 1) The location system of claim 1 wherein the wireless transceiver module includes a cellular transceiver module configured to transmit the present location and the present floor to the rental server via a cellular network. ### Claim 14 (depends on 13) The location system of claim 13 further comprising: a computing device of a renter of the shared vehicle, wherein the rental server is configured to selectively transmit the present location and the present floor of the shared vehicle to the computing device of the renter. ### Claim 15 (depends on 1) The location system of claim 1 wherein: the wireless transceiver module is configured to transmit the present location and the present floor to a computing device of a renter of the shared vehicle; the location system further includes the computing device; and the computing device is separate from the shared vehicle and is configured to transmit the present location and the present floor received from the wireless transceiver module of the shared vehicle to the rental server via a cellular network. ### Claim 16 (depends on 15) The location system of claim 15 further comprising: a second computing device of a second renter of the shared vehicle, wherein the rental server is configured to selectively transmit the present location and the present floor of the shared vehicle to the second computing device of the second renter. ### Claim 17 (depends on 16) The location system of claim 16 wherein the second computing device is configured to display, on a display, an indicator of boundaries of the parking structure and the present location and floor of the shared vehicle within the parking structure. ### Claim 18 A method for a shared vehicle, comprising: when a signal strength of a global position system (GPS) module is less than a predetermined signal strength, determining a present location of the shared vehicle within a parking structure based on measurements from one or more sensors of the shared vehicle; when the signal strength of the GPS module is less than the predetermined signal strength, determining a present floor of the parking structure on which the shared vehicle is located; when the shared vehicle is off and parked within the parking structure, when a second signal strength of a cellular transceiver module of the shared vehicle is less than a second predetermined signal strength,
