Abstract

A system and method of operating a mobile hotspot at a vehicle. The system involves use of a vehicle that includes a battery and a charging port, wherein the charging port connects the vehicle to an external power source and is electrically connected to the battery to provide the battery with electrical power from the external power source when connected; a wireless access point, wherein the access point is powered by the battery in the vehicle and wherein the access point wirelessly provides Internet access to one or more wireless devices located in or within a proximity of the vehicle; and a controller, wherein the controller enables operation of the access point while the vehicle is powered off when the vehicle is connected to the external power source via the charging port.

Claims

1. A method of operating a mobile hotspot at a vehicle, wherein the vehicle includes vehicle electronics that include a mobile hotspot which operates to provide wireless connectivity for one or more non-vehicle wireless devices located in the vehicle or within a proximity of the vehicle, wherein the method is carried out by the vehicle electronics and comprises the steps of:

(a) determining whether a vehicle battery used to power the mobile hotspot is connected to an external charging device that supplies charging power to the vehicle battery, the external charging device being located at a fixed geographical location;

(b) determining whether at least one of the one or more non-vehicle wireless devices are connected to the mobile hotspot;

(c) operating the mobile hotspot while the vehicle is powered off based on the determinations in step (a) and step (b), wherein the mobile hotspot is operated when it is determined that the vehicle battery used to power the mobile hotspot is connected to the external charging device that supplies charging power to the vehicle battery, and when it is determined that the at least one non-vehicle wireless devices are connected to the mobile hotspot; and

(d) turning off the mobile hotspot when it is determined that the vehicle battery used to power the mobile hotspot is not connected to the external charging device that supplies charging power to the vehicle or when it is determined that none of the one or more non-vehicle wireless devices are connected to the mobile hotspot.

2. The method of claim 1, wherein the determination in step (a) further comprises receiving a user request to operate the mobile hotspot.

3. The method of claim 2, wherein receiving the user request further comprises receiving the user request via a software application installed on a non-vehicle device.

4. The method of claim 1, wherein the determination in step (b) further comprises determining that the at least one non-vehicle wireless devices are connected to the mobile hotspot when the vehicle is switched from being powered on to being powered off, and wherein step (b) further comprises receiving a user request to continue operation of the mobile hotspot.

5. The method of claim 1, wherein the determination in step (a) further comprises determining that one or more conditions of a user-selectable vehicle configuration option are met.

6. The method of claim 5, wherein the user-selectable vehicle configuration option includes one or more geographic locations and wherein the user-selectable vehicle configuration option causes the vehicle electronics to operate the mobile hotspot while the vehicle is powered off when the vehicle is at one of the one or more geographic locations.

7. The method of claim 1, further comprising the step of subsequently terminating operation of the mobile hotspot based on determining that the vehicle battery is in a low battery state.

8. A method of controlling operation of a mobile hotspot at a vehicle, comprising the steps of:

(a) operating a mobile hotspot at the vehicle while the vehicle is powered on, wherein the vehicle includes vehicle electronics that include the mobile hotspot which provides wireless connectivity for one or more non-vehicle wireless devices located in the vehicle or within a proximity of the vehicle;

(b) subsequently after step (a), maintaining operation of the mobile hotspot for a period of time after the vehicle is powered off;

(c) detecting that the vehicle is connected to an external power source during operation of the mobile hotspot for the period of time after the vehicle is powered off, the external power source being located at a fixed geographical location and being separate from the vehicle electronics; and

(d) continuing to operate the mobile hotspot in response to step (c) such that the operation of the mobile hotspot is continued after the vehicle is powered off when the vehicle is connected to the external power source within the period of time after the vehicle is powered off.

9. The method of claim 8, wherein step (b) further comprises determining that at least one of the one or more non-vehicle wireless devices is connected to the mobile hotspot and maintaining operation of the mobile hotspot in response to the determination irrespective of whether the vehicle is connected to the external power source.

10. The method of claim 9, further comprising the step of detecting that at least one of the one or more non-vehicle wireless devices has been disconnected from the mobile hotspot and, subsequently, terminating operation of the mobile hotspot.

11. The method of claim 8, further comprising prompting an operator of the vehicle upon the vehicle powering off, to request an input indicating if the vehicle should continue operate the mobile hotspot.

12. The method of claim 8, further comprising providing a notification to an operator of the vehicle upon the vehicle powering off that the vehicle will continue to operate the mobile hotspot.
