Abstract

A method of authorizing access and operation for vehicle sharing via a portable device. A request reservation is generated to reserve a vehicle via a portable device carried by a user. The reservation includes a portable device identifier and reservation details. Authentication keys are transmitted to the portable device and a plug-in device coupled to the vehicle in response to a successful authorization. The plug-in device is used to perform vehicle access and vehicle operations of the vehicle. The authentication keys enable the portable device and the plug-in device to be paired for enabling vehicle access and operations. An authorization is executed between the portable device carried by a user and a plug-in device coupled to the vehicle. Access to the vehicle operations are enabled in response to a successful authorization.

executing an authorization between the portable device carried by a user and a plug-in device coupled to the vehicle;

enabling access to vehicle operations in response to a successful authorization.

4. A method of claim 1 wherein generating the request reservation to reserve the vehicle via the portable device further comprises the steps of:

communicating the request reservation to a remote entity by the portable device;

generating a signed token by the remote entity;

transmitting the signed access token to the portable device within a predetermined time from the reservation request.

5. The method of claim 4 further comprising the step of sending a confirmation to the portable device.

6. The method of claim 1 wherein the step of executing an authorization between the portable device carried by the user and the plug-in device further comprises the steps of:

receiving, by the portable device, an interrogation signal transmitted by a communication node module of the vehicle;

pairing the portable device and the communication node module of the vehicle;

transmitting a notification, by the portable device, to the communication node module relating to the proximity of the portable device to the vehicle; and

validating the portable device to the passive entry/passive start system of the vehicle utilizing an authorization key validation technique.

7. The method of claim 6 wherein the communication node module includes a Bluetooth low energy (BLE) module, and wherein the interrogation signal is transmitted as a BLE signal.

8. The method of claim 7 wherein receiving by the portable device the interrogation signal transmitted by the BLE module of the vehicle further comprises the steps of:

monitoring the communication bus for communication over a predetermined period of time;

transmitting a wake-up call to the VCP in response to communication on the communication bus during the predetermined period of time;

otherwise entering sleep mode.

9. The method of claim 7 wherein validating the portable device to the passive entry/passive start system of the vehicle utilizing authorization key validation further comprises the steps of:

transmitting a wake-up call by the BLE module over the communication bus to the VCP;

communicating a request for token validation to the remote entity via the VCP;

verifying, by the remote entity, a validity of the token;

transmitting a validation response to the portable device and the plug-in device;

transmitting an authorization key wirelessly from the portable device to the BLE module;

communicating the authorization key received by the BLE module to the plug-in device via the communication bus;

validating, by the plug-in device, the authorization key received from the portable device; and

communicating to the portable device an authorized pairing with the plug-in device.

10. The method of claim 9 wherein the step of communicating a request for token validation to the remote entity via the VCP includes communicating a request for token validation from the portable device to the remote entity if a communication path from the VCP to the remote entity is not available.

11. The method of claim 9 wherein the step of verifying by the remote entity that the token is still valid comprises the following steps:

determining by the remote entity of the validity of the token;

in response to determining the token is valid, determining whether a valid command request is being made by the portable device; and

transmitting a confirmation to the portable device that the command request is successfully received and authorized, otherwise, transmitting a failure message to the portable device in response to the either token being invalid or the command request being invalid.

12. The method of claim 1 wherein enabling access to the vehicle and vehicle operations in response to a successful authorization further comprises the steps of:

actuating a command on the portable device relating to a vehicle operation;

transmitting the command from the portable device to the BLE module;

receiving the command by the BLE module and communicating the command to the plug-in device;

transmitting, by the plug-in device, the command to the passive entry/passive start system;

actuating the selected vehicle function in response to receiving the command.

13. The method of claim 12 wherein the step of transmitting the command to the passive entry/passive start system comprises:

transmitting, by the plug-in device, a wake-up call on the communication bus to the passive entry/passive start system; and

transmitting the command on the communication bus to the passive entry/passive start system.

14. The method of claim 12 wherein plug-in device further includes a keyfob printed circuit board for communicating indirectly with the passive entry/passive start system, wherein the step of transmitting the command to the passive entry/passive start system further comprises the steps of:

communicating the command to the keyfob printed circuit board; and

transmitting the command to the passive entry/passive start system.

15. The method of claim 12 further comprising the step of transmitting to the portable device a confirmation identifying execution of the command.

16. The method of claim 1 wherein executing the authorization between the portable device carried by the user and the plug-in device further comprises the steps of:

determining whether the command is a remote start operation;

validating the remote start command by the remote entity;

communicating, by the remote entity, to a remote call service center the command for the remote start;

executing, by the call service center, the remote start of the vehicle.

17. The method of claim 16 further comprising the step of communicating an error to the portable device that the portable device needs to be closer to the vehicle in response to the command being other than a remote start operation.

18. The method of claim 12 wherein enabling access to the vehicle and vehicle operations in response to a successful authorization further comprises the steps of:

detecting the portable device within an interior of the vehicle by the BLE module in response to actuating the vehicle function;

supplying power to the plug-in device, wherein the plug-in device stores the authorization keys for enabling vehicle start functions;
