Abstract

Responsive to location information received from a positioning system indicating a vehicle location corresponding to a predefined location, a controller of a vehicle broadcasts a notification including the vehicle location. Responsive to receiving a request including a device location from a mobile device having interpreted the broadcast, the controller permits access to the vehicle responsive to a difference between the device location and the vehicle location being less than a predefined threshold distance.

First claim

What is claimed is:

1. A system comprising: a controller of a vehicle, configured to: responsive to location information received from a positioning system indicating a vehicle location corresponding to a predefined location, offset the vehicle location using a pre-shared location offset, generated by a location offset generator, and broadcast a notification including the vehicle location as offset, and responsive to receiving a request including a device location from a mobile device having interpreted the broadcast, permit access to the vehicle responsive to a difference between the device location and the vehicle location being less than a predefined threshold distance.

2. The system of claim 1 , wherein the pre-shared location offset is an offset value received from a remote server responsive to a ride-share request received by the server from the mobile device.

3. The system of claim 1 , wherein the controller is further configured to use the pre-shared location offset to reverse a location offset applied to the device location by the mobile device to determine the difference.

4. The system of claim 1 , wherein the request further includes a device identifier and wherein the controller is further configured to additionally authenticate the device identifier to permit the access to the vehicle.

5. The system of claim 1 , wherein the controller is further configured to:
encrypt the as broadcast notification using an encryption key; and
permit access responsive to receiving the request from the mobile device having decrypted the broadcast.

6. The system of claim 5 , wherein the controller is further configured to receive the encryption key from a remote server responsive to a ride-share request received by the server from the mobile device.

7. The system of claim 1 , wherein the predefined location is a pick-up location of a ride-share request sent by the mobile device.

8. A method comprising: responsive to a vehicle located at a pick-up location, offsetting the vehicle location using a pre-shared location offset, generated by a location offset generator, and broadcasting an encrypted combination of an identifier and the offset location; and responsive to receiving an encrypted request including both an identifier and a location of a mobile device receiving the broadcast, decrypting the request and permitting access to the vehicle responsive to the device location being within a predefined distance to the pick-up location.

9. The method of claim 8 further comprising reversing, using the pre-shared location offset, a location offset applied to the device location by the mobile device for comparing the vehicle and device locations.

10. The method of claim 9 , wherein the pre-shared location offset is an offset value received from a remote server responsive to a ride-share request received by the server from the mobile device.

11. The method of claim 8 , wherein the established pick-up location is based on a ride-share request received by a remote server from the mobile device.

12. The method of claim 8 , wherein the encrypted combination is encrypted using an encryption key received from a remote server responsive to a ride-share request received by the server from the mobile device.

13. The method of claim 8 further comprising decrypting the request using a decryption key received from a remote server responsive to a ride-share request received by the server from the mobile device.

14. A system comprising: a mobile device configured to: responsive to receiving, from a vehicle, an access notification indicating that access to the vehicle is available, send to the vehicle an access request including both a device identifier and device location according to location information received from a device positioning system offset generator using a predefined offset value, and responsive to receiving an access confirmation from the vehicle having interpreted the request, display a confirmation notification.

15. The system of claim 14 , wherein the receiving of the access confirmation from the vehicle is responsive to a difference between the device location and a vehicle location identified according to a positioning system of the vehicle being less than a predefined threshold distance.

16. The system of claim 14 , wherein the access notification is responsive to a ride-share request sent by the mobile device.

17. The system of claim 14 , wherein the access notification further includes a vehicle location and wherein the mobile device is further configured to send the access request responsive to the vehicle location being within a predefined threshold distance of a pick-up location associated with a ride-share request sent by the mobile device.

18. The system of claim 1 , wherein the pre-shared location offset includes one of a random and a pseudo-random number of degrees, minutes, and seconds by which to offset at least one of latitude and longitude of the vehicle location.

19. The system of claim 1 , wherein the pre-shared location offset includes a random value between a predefined minimum range and a predefined maximum range from the vehicle.

20. The system of claim 1 , wherein the pre-shared location offset includes a decimal value by which to offset a decimal equivalent of geographic coordinates of the vehicle location.
