Abstract

A system for communicating with a vehicle includes a control module equipped with a remote keyless entry (RKE) receiver and configured to control vehicle functions in response to a RKE signal. The system includes a fob equipped with a RKE transmitter and a short range transceiver, such as BLUETOOTH™, IEEE 802.11, or near field communication (NFC). The fob transmits a RKE signal in response to receiving a message from a consumer device, such as a cellular phone, smart phone, tablet computer, or personal computer equipped with a short range transceiver, enabling the user to control the vehicle from the consumer device. The system may be configured to transmit vehicle status information to the consumer device. The control module may include a third short range transceiver that communicates with the consumer device when the distance is between the vehicle and the consumer device is less than the distance threshold.

Claims

1. A system for communicating with a vehicle comprising:

a control module configured to be mounted in the vehicle, said control module comprising a first RKE receiver, said control module further configured to control a vehicle function in response to a RKE signal received by the first RKE receiver;

a fob equipped with a first RKE transmitter and a first short range transceiver, wherein said first RKE transmitter is configured to transmit the RKE signal in response to the first short range transceiver receiving a gateway message via a first communication gateway; and

a consumer device equipped with a second short range transceiver, wherein the consumer device is configured to transmit the gateway message to the first short range transceiver via the first communication gateway in response to an action by a user, and thereby enable the user to control the vehicle function from the consumer device via the fob, wherein

the second short range transceiver communicates the gateway message to the first short range transceiver via the first communication gateway if a communication distance between the vehicle and the consumer device is greater than a distance threshold, and the second short range transceiver transmits the gateway message to the third short range transceiver via the second communication gateway if the communication distance is less than the distance threshold.

2. The system in accordance with claim 1, wherein the control module is equipped with a second RKE transmitter, the fob is equipped with a second RKE receiver, and said system is further configured to communicate a vehicle status message from the control module to the consumer device via the fob.

3. The system in accordance with claim 1, wherein the first short range transceiver and the second short range transceiver include one of a BLUETOOTH™

transceiver, an IEEE 802.11 transceiver, and a Near Field Communication network transceiver.

4. The system in accordance with claim 1, wherein the control module further comprises a third short range transceiver configured to receive the gateway message via a second communication gateway, wherein the consumer device is configured to transmit the gateway message to the third short range transceiver via the second communication gateway in response to the action by the user and thereby enable the user to control the vehicle function from the consumer device without the fob, wherein the system is configured such that the second short range transceiver communicates the gateway message to the first short range transceiver via the first communication gateway if a communication distance between the vehicle and the consumer device is greater than a distance threshold, and the second short range transceiver transmits the gateway message to the third short range transceiver via the second communication gateway if the communication distance is less than the distance threshold.

5. The system in accordance with claim 4, wherein the third short range transceiver includes one of a BLUETOOTH™

transceiver, an IEEE 802.11 transceiver, and a Near Field Communication network transceiver.

6. A consumer device configured to enable a user to access vehicle status information and control vehicle devices comprising:

a second short range transceiver, wherein the consumer device is configured to transmit a gateway message to a control module in a vehicle or a fob, said gateway message transmitted in response to an action by the user in order to enable the user to control a vehicle function from the consumer device, wherein the second short range transceiver is configured to transmit the gateway message to a first short range transceiver in the fob via a first communication gateway if a communication distance between the vehicle and the consumer device is greater than a distance threshold, and the second short range transceiver is further configured to transmit the gateway message to a third short range transceiver in the control module via a second communication gateway between the second short range transceiver and the third short range transceiver if the communication distance is less than the distance threshold; and

a user input means to enable the user to select the gateway message, wherein

the second short range transceiver communicates the gateway message to the first short range transceiver via the first communication gateway if a communication distance between the vehicle and the consumer device is greater than a distance threshold, and the second short range transceiver transmits the gateway message to the third short range transceiver via the second communication gateway if the communication distance is less than the distance threshold.

7. The consumer device in accordance with claim 6, wherein the consumer device is further configured to display the vehicle status information in response to receiving the gateway message via the first communication gateway or the second communication gateway.

8. The consumer device in accordance with claim 6, wherein the second short range transceiver includes one of a BLUETOOTH™

transceiver, an IEEE 802.11 transceiver, and a Near Field Communication network transceiver.

9. The consumer device in accordance with claim 6, wherein the consumer device further comprises a voice command detection means, and the action is a voice command.

10. The consumer device in accordance with claim 6, wherein the consumer device further comprises a motion detection means, and the action is a predetermined pattern of motions of the consumer device.

11. A method of communicating with a vehicle equipped with a control module configured to control a vehicle function in response to a RKE signal, said method comprising steps of:

detecting an action by a user of a consumer device;

transmitting a gateway message to a fob via a first communication gateway, wherein said gateway message is based on the action;

transmitting the RKE signal corresponding to the gateway message from the fob to the control module; and

controlling the vehicle function in response to the action, wherein transmitting the gateway message to the fob occurs when a communication distance between the consumer device and the vehicle is greater than a distance threshold, said method further comprising a step of transmitting the gateway message from the consumer device to the control module via a second communication gateway when the communication distance is less than the distance threshold.

12. The method of claim 11 further comprising the steps of:

transmitting the RKE signal corresponding to vehicle status information from the control module to the fob; and

transmitting the gateway message corresponding to the RKE signal transmitted from the fob to the consumer device.

13. The method of claim 11 further comprising the step of disabling a second RKE transceiver when the gateway message is transmitted from the consumer device to the control module.

14. The method of claim 11 further comprising the step of transmitting a vehicle status message from the control module to the consumer device.

15. The method of claim 11 further comprising the step of enabling a second RKE transceiver when the communication distance between the vehicle and the consumer device is greater than the distance threshold.
