Abstract

A communication system and a method of identifying a target vehicle using application software on a mobile device. The method includes the steps of receiving at the mobile device a wireless signal transmitted from a transmitter at the target vehicle, wherein the wireless signal is received using an imaging detector in the mobile device; identifying that the target vehicle is a source of the wireless signal based on characteristics of the wireless signal; and in response to the identification, displaying to a user on a display of the mobile device an indication of an identity of the target vehicle.

Claims

1. A method of identifying a target vehicle using application software on a mobile device, the method comprising the steps of:

transmitting a request for a vehicle transportation service to a remote server, wherein the remote server is configured to send security data to the target vehicle and the mobile device after receiving the request for the vehicle transportation service;

receiving at the mobile device a wireless signal transmitted from a transmitter at the target vehicle, wherein the wireless signal is received using an imaging detector in the mobile device;

identifying that the target vehicle is a source of the wireless signal based on characteristics of the wireless signal, wherein the characteristics of the wireless signal includes information concerning the mobile device and/or the target vehicle that was shared with the mobile device and/or the target vehicle in response to establishing that the target vehicle is to be used for the vehicle transportation service;

capturing video image data using a camera included on the mobile device, wherein the captured video image data includes an image of the target vehicle;

in response to the identification, displaying to a user on a display of the mobile device an indication of an identity of the target vehicle and the captured video image data, wherein the indication of the identity of the target vehicle is represented by a computer-generated graphical element, and wherein the computer-generated graphical element is overlaid on the captured video image data; and

establishing a short-range wireless communication (SRWC) link between the mobile device and the target vehicle using the security data that is received from the remote server.

2. The method of claim 1, wherein the wireless signal is comprised of light, wherein the mobile device receives the wireless signal when the mobile device is within a line-of-sight (LOS) of the transmitter.

3. The method of claim 1, wherein the characteristics of the wireless signal include a predetermined sequence of light pulses.

4. The method of claim 3, wherein the predetermined sequence of light pulses are representative of a mobile device identifier provided by the mobile device to the remote server.

5. The method of claim 1, wherein the characteristics of the wireless signal comprise encoded, infrared (IR) light pulses.

6. The method of claim 1, wherein the video image data is part of a live, unrecorded video feed from the imaging detector of the mobile device, and wherein the camera comprises the imaging detector.

7. The method of claim 1, further comprising after the displaying step, validating the target vehicle using the short range wireless communication (SRWC) link between the target vehicle and the mobile device, wherein the validation includes using a first virtual key provided to the mobile device from the remote server and a second virtual key provided to the target vehicle from the remote server.

8. The method of claim 1, wherein the transmitting step is carried out prior to the receiving, identifying, and displaying steps, wherein the vehicle transportation service request includes an identifier, time data, and geographical data, each of the identifier, time data, and geographical data being associated with the target vehicle arriving to meet the user of the mobile device.

9. The method of claim 8, wherein the wireless signal includes data associated with the identifier provided by the mobile device to the remote server.

10. A method of identifying a target vehicle using application software on a mobile device, the method comprising the steps of:

transmitting from the mobile device a vehicle transportation service request for a vehicle transportation service to a remote server, wherein the remote server is configured to send security data to the mobile device and the target vehicle;

in response to the transmitted request, receiving at an imaging detector of the mobile device a beacon signal that includes identifying information, wherein the beacon signal is comprised of light;

in response to the receiving the beacon signal, identifying that a source of the beacon signal is the target vehicle based on the identifying information, wherein the identifying information of the beacon signal includes information concerning the mobile device and/or the target vehicle that was shared with the mobile device and/or the target vehicle in response to establishing that the target vehicle is to be used for the vehicle transportation service;

capturing video image data using a camera included on the mobile device, wherein the captured video image data includes an image of the target vehicle;

in response to the identifying step, displaying on a display of the mobile device the captured video image data that includes the image of the target vehicle and a computer-generated graphical element overlaying or merged with the image of the target vehicle, wherein the image of the target vehicle and the computer-generated graphical element are arranged to enable a user of the mobile device to identify the target vehicle; and

establishing a short-range wireless communication (SRWC) link between the mobile device and the target vehicle using the security data that is received from the remote server.

11. The method of claim 10, further comprising:

in response to the transmitting step, receiving at the mobile device a cryptographic key from the remote server; and

after the identifying step,

using the cryptographic key, validating the target vehicle using a short range wireless communication (SRWC) link between the target vehicle and the mobile device.

12. The method of claim 10, wherein the vehicle transportation service request includes a mobile device identifier, a geographic pick-up location, and time data associated with a time when the mobile device user desires to be picked-up.

13. The method of claim 12, wherein the identifying information used in the identifying step is associated with the mobile device identifier transmitted with the vehicle transportation service request.

14. The method of claim 10, wherein the beacon signal is comprised of predetermined sequence of light pulses, wherein the light pulses include light in the infrared band.

15. A computer program product, comprising a non-transitory computer-readable medium for a mobile device, comprising computer program instructions that enable the mobile device to identify a target vehicle based on a wireless beacon signal transmitted from the target vehicle that is comprised of light, said computer program product comprising:

instructions for transmitting from the mobile device a vehicle transportation service request for a vehicle transportation service to a remote server, wherein the remote server is configured to send security data to the mobile device and the target vehicle;

instructions for receiving at an imaging detector of the mobile device a beacon signal that includes identifying information in response to the transmitted request;

instructions for identifying that a source of the beacon signal is the target vehicle based on the identifying information, wherein the identifying information of the beacon signal includes information concerning the mobile device and/or the target vehicle that was shared with the mobile device and/or the target vehicle in response to establishing that the target vehicle is to be used for the vehicle transportation service;

instructions for capturing image data using a camera included on the mobile device, wherein the captured image data includes an image of the target vehicle;

instructions for, in response to executing the identifying instructions, displaying on a display of the mobile device augmented reality (AR) video image data that includes the image of the target vehicle and a computer-generated graphical element overlaying or merged with the image of the target vehicle, wherein the AR video image data is arranged to assist a user of the mobile device to identify and locate the target vehicle; and

instructions for establishing a short-range wireless communication (SRWC) link between the mobile device and the target vehicle using the security data that is received from the remote server.
