Abstract

A system for activating a vehicle function includes a vehicle and at least one remote controller. The least one remote controller is configured to receive, prior to a user approaching their vehicle, a request from the user to have a vehicle function activated when the user approaches their vehicle, and to periodically transmit request signals indicating the request. The vehicle defines a first communication range with the at least one remote controller for communication of the request signals. The vehicle is vehicle configured to receive at least one of the request signals upon the at least one remote controller'"'"'s entry into the first communication range, and generate an instruction to activate the vehicle function in accordance with the request.

Claims

1. A system for activating a vehicle function, comprising:

a remote controller, the remote controller configured to;

receive, prior to a user approaching an associated vehicle, a request from the user to have a vehicle function activated when the user approaches the associated vehicle, and

transmit request signals indicating the request at predetermined intervals of time from receipt of the request from the user until at least a first request signal is received by a vehicle controller; and

a first communication range defined around the vehicle controller in which the vehicle controller is capable of receiving the request signals from the remote controller, wherein the request from the user is made outside of the first communication range, the vehicle controller configured to generate an instruction to activate the vehicle function in accordance with the request when at least the first request signal is received by the vehicle controller.

2. The system of claim 1, wherein the vehicle controller defines a second communication range with the at least one remote controller for communication of detection signals, and the vehicle controller is further configured to:

transmit one or more detection signals to the remote controller, the transmission indicating receipt of at least the first request signal from the remote controller when the remote controller enters the second communication range, and the remote controller is further configured to cease transmission of the request signals when the transmission indicating receipt by the vehicle controller is received.

3. The system of claim 2, wherein the second communication range corresponds to a predetermined zone within the first communication range for permitting activation of the vehicle function in accordance with the request.

4. The system of claim 2, wherein at least one of the one or more detection signals are low frequency radio signals.

5. The system of claim 2, wherein the second communication range is approximately one meter.

6. The system of claim 1, wherein the remote controller is further configured to continue to transmit the request signals at the predetermined intervals upon receiving the request, without receiving an additional request from the user when the user approaches their vehicle at a future time.

7. The system of claim 1, wherein the vehicle further includes at least one user feedback device, and the vehicle controller is further configured to:

control the user feedback device to indicate its receipt of at least one of the request signals.

8. The system of claim 1, wherein the request signals are radio frequency signals, and the first communication range is approximately sixty meters.

9. The system of claim 1, wherein the first communication range is approximately sixty meters.

10. The system of claim 1, wherein the vehicle further includes a moveable closure panel, and the vehicle function is movement of a position of the closure panel from a closed position to an open position.

11. A vehicle, comprising:

a remote controller configured to receive a request from the user to have a vehicle function activated when the user approaches the vehicle;

a receiver, the receiver defining a first communication range and a second communication range with the remote controller, the first communication range being larger than the second communication range, the remote controller further configured to transmit request signals indicating the request at predetermined intervals of time from receipt of the request from the user made outside of the first communication range; and

a system for activating the vehicle function, the system configured to;

upon entry of the remote controller into the first communication range, receive one or more vehicle function activation request signals from the remote controller over the first communication range while the remote controller is outside of the second communication range,

enter a welcome state for the remote controller,

exchange one or more detection signals with the remote controller over the second communication range, and

generate an instruction to activate the vehicle function based on the receipt of the one or more vehicle function activation request signals and the exchange of the one or more detection signals.

12. The vehicle of claim 11, wherein the second communication range corresponds to a predetermined zone within the first communication range for permitting activation of the vehicle function.

13. The vehicle of claim 11, wherein the system is further configured to transmit one or more return signals indicating its receipt of the one or more vehicle function activation request signals.

14. The vehicle of claim 11, further comprising:

at least one user feedback device, wherein the system is further configured to;

generate an instruction to activate the user feedback device to indicate its receipt of the one or more vehicle function activation request signals.

15. The vehicle of claim 11, wherein the one or more vehicle function activation request signals are radio frequency signals.

16. The vehicle of claim 11, wherein the first communication range is approximately sixty meters.

17. The vehicle of claim 11, wherein at least one of the one or more detection signals are low frequency radio signals.

18. The vehicle of claim 11, wherein the second communication range is approximately one meter.

19. The vehicle of claim 11, further comprising:

a moveable closure panel, wherein the vehicle function is movement of a position of the closure panel from a closed position to an open position.
