Abstract

Methods and systems are provided. One method includes processing operations to share electronic keys (e-keys). The method includes receiving a request to share an electronic key (e-key) of a vehicle with a recipient device. The request to share the e-key is initiated by sending a message to the recipient device using a sharing device. The method includes processing the request to validate the request to share the e-key, as received from the sharing device having associated therewith a registered owner e-key. Processing the request includes generating the e-key securely by the sharing device and registering the e-key that was generated with a server associated with a manufacturer of the vehicle. The method includes enabling the e-key for use on the vehicle by the recipient device responsive to said processing of the request. The request to share the e-key includes enabling a setting to apply a privilege level for use of the vehicle via the e-key. The privilege level provides one or more conditions of use of the vehicle via the e-key.

First claim

What is claimed is:

1. A method for sharing electronic keys (e-keys), comprising:
processing a request to share an electronic key (e-key) of a vehicle with a recipient device, the request to share the e-key being received responsive to a message being sent to the recipient device from a sharing device;
determining that the request to share the e-key was associated with a registered owner e-key;
processing instructions to enable the e-key to be securely generated for use by the recipient device; and
saving information regarding the e-key with a server associated with a manufacturer of the vehicle;
wherein the e-key is enabled for said use on the vehicle by the recipient device.

2. The method of claim 1 , wherein the request to share the e-key includes a setting to assign a privilege level for use of the vehicle when used via the e-key, the privilege level provides one or more conditions of use of the vehicle.

3. The method of claim 2 , wherein the one or more conditions of use defined via the privilege level is one of a geographic restriction for where the vehicle is allowed to be used, or a speed restriction, or an occupancy restriction, or a time frame of use, or an expiration-time of use, or unlocking of the vehicle, or driving of the vehicle, or combinations of two or more thereof.

4. The method of claim 1 , wherein the request is enabled via an application executed via the sharing device, the application provided by said manufacturer of the vehicle to enable initiation of sharing of the e-key, the application is associated with an owner account for the vehicle.

5. The method of claim 1 , wherein responsive to said request, the e-key is generated, the generation of the e-key includes one or more processes executed by the server associated with the manufacturer of the vehicle, one or more processes executed by one or more additional server, one or more processes executed by the recipient device, one or more processes executed by a computer, or a combination of two or more thereof.

6. The method of claim 1 , further comprising,
encrypting the e-key, the e-key being encrypted using public/private key pairs that are generated and used for security in communication.

7. The method of claim 1 , further comprising,
receiving a deactivation request, the deactivation request is used to disable the e-key for use by the recipient device on the vehicle.

8. The method of claim 1 , wherein the message to share and enable the e-key for the recipient device is communicated over a network, the communication enables processing by one or more servers or devices, and said one or more servers or devices include a server associated with the sharing device or the recipient device, and the server associated with the manufacturer of the vehicle.

9. The method of claim 1 , wherein the recipient device is identified by one or more of an email address, a phone number, a text message, a message address, a notification, a link, a web address, a social network address, or combination of two or more thereof.

10. The method of claim 1 , wherein an application provided by a manufacturer of the vehicle includes a graphical user interface for registering the registered owner e-key for the vehicle and sharing of the e-key with one or more recipient devices.

11. The method of claim 1 , wherein the e-key enabled for use on the vehicle using the recipient device enables unlocking and starting the vehicle when the recipient device uses the e-key with the vehicle, and the e-key is associated with at least one privilege associated with a type of operational use of the vehicle.

12. A system for enabling use and sharing of an electronic key (e-key) for a vehicle, comprising:
a server associated with a manufacturer of the vehicle, the server is configured to interface with an application provided by the manufacturer of the vehicle, the application provides access to data and logic for enabling sending a request to share the e-key for the vehicle with a recipient device;
the request to share is configured to be initiated by a message originating from the recipient device, and responsive to the request, processing the request to securely generate the e-key;
the server associated with the manufacturer of the vehicle assisting in enabling the e-key for use on the vehicle by the recipient device.

13. The system of claim 12 , wherein the request to share the e-key includes enabling a setting to apply a privilege level for use of the vehicle via the e-key, the privilege level provides one or more conditions of use of the vehicle via the e-key.

14. The system of claim 12 , wherein the e-key is encrypted, and wherein encryption uses a public/private process for security.

15. The system of claim 12 , wherein the application includes a selectable option for disabling the e-key from use by the recipient device on the vehicle.

16. The system of claim 12 , wherein the e-key enabled for use on the vehicle using the recipient device enables unlocking and starting the vehicle when the recipient device uses the e-key with the vehicle, and the e-key is associated with at least one privilege associated with a type of operational use of the vehicle.

17. A method for providing access to a vehicle, comprising:
receiving confirmation of a sharing request being sent for an electronic key (e-key) for use of the vehicle by a recipient device, the sharing request originates responsive to a message transferred by an owner device to the recipient device;
receiving confirmation of the sharing request from the recipient device;
processing data related to the message by a server associated with a manufacturer of the vehicle, said processing data is performed to enable the e-key for use by the recipient device on the vehicle; and
enabling the e-key for use by the recipient device on the vehicle.

18. The method of claim 17 , wherein the e-key is associated with at least one privilege associated with use of the vehicle, the at least one privilege is defined based on a setting associated with the sharing request, and wherein the recipient device is one of a smartphone, or a smartwatch, or smart glasses, or a computer, or a digital assistant, or a key fob, and wherein the e-key is unique for said sharing request and said use by said recipient device.

19. The method of claim 17 , wherein the e-key is caused to be generated by either one of said owner device, the server, the recipient device, a computer, the vehicle, or a combination of two or more thereof.

20. The method of claim 17 , wherein the e-key is securely generated for the recipient device, and wherein the owner device has an owner e-key that was initially generated for the owner device to enable said sharing request, and the e-key is encrypted, and wherein encryption uses a public/private process for security.

21. The method of claim 17 , wherein the e-key, once enabled, provides access to information via the recipient device regarding a level of charge of a battery of the vehicle for when the vehicle is an electric vehicle (EV).

22. The method of claim 17 , wherein the e-key enabled for use on the vehicle using the recipient device enables unlocking and starting the vehicle when the recipient device uses the e-key with the vehicle, and the e-key is associated with at least one privilege associated with a type of operational use of the vehicle.

23. A system for enabling use and sharing of an electronic key (e-key) for a vehicle, comprising:
an on-board computer of the vehi
