Abstract

A keyless function system and method includes a portable device having a vehicle function actuator thereon for initiating operation of a vehicle function. The portable device transmits an actuation signal to the vehicle when the vehicle function actuator is actuated. The receiver onboard the vehicle receives the actuation signal from the portable device. A controller onboard the vehicle and operatively connected to the receiver determines at least one of: whether the vehicle is located at a predetermined location or whether the portable device is located less than a predetermined distance from the vehicle. The controller selectively commands performance of the vehicle function when the actuation signal is received by the receiver based on at least one of: whether the vehicle is at the predetermined location or the portable device is less than the predetermined distance from the vehicle.

Claims

1. A keyless function method for a vehicle, comprising:

receiving an actuation signal from a portable device for performing a vehicle function;

determining a location of the vehicle; and

selectively performing the vehicle function when the actuation signal is received based on the location as determined in the preceding step, wherein selectively performing the vehicle function based on the location includes;

determining whether the location of the vehicle matches a predetermined location; and

calculating a distance between the portable device and the vehicle when determined that the location of the vehicle matches the predetermined location;

determining whether the distance calculated is less than a predetermined distance, and

performing the vehicle function when the location of the vehicle matches the predetermined location only when determined that the distance is less than the predetermined amount.

2. The method of claim 1 wherein calculating the distance between the portable device and the vehicle includes receiving a received signal strength indication (RSSI) from the portable device to indicate the distance between the portable device and the vehicle.

5. The method of claim 1 further including:

selecting the predetermined location through an interface of a vehicle navigational system.

6. The method of claim 1 wherein determining whether the location of the vehicle matches the predetermined location includes an onboard vehicle communication system communicating with a communication device located at or adjacent the predetermined location.

7. The method of claim 1 wherein the vehicle function is at least one of powered opening of a powered tailgate, powered opening of a powered sliding door or powered opening of a trunk.

8. The method of claim 7 wherein the vehicle function is powered opening of a powered tailgate.

9. The method of claim 1 further including determining the location of the portable device relative to the vehicle.

10. The method of claim 9 wherein selectively performing the vehicle function includes determining whether the location of the portable device is more than a predetermined distance relative to the vehicle.

11. The method of claim 9 further including:

calculating a distance between the location of the portable device and the vehicle; and

determining whether the distance calculated in the preceding step is less than a predetermined distance.

12. The method of claim 11 wherein calculating the distance between the portable device and the vehicle includes receiving a received signal strength indication (RSSI) from the portable device to indicate the distance between the portable device and the vehicle.

3. A keyless function method for a vehicle, comprising:

receiving an actuation signal from a portable device for performing a vehicle function;

determining a location of the vehicle; and

selectively performing the vehicle function when the actuation signal is received based on the determined location, wherein selectively performing the vehicle function based on the location includes;

determining whether the location of the vehicle matches a predetermined location, and

performing the vehicle function is based on the determination of whether the location of the vehicle matches the predetermined location, and

wherein performing the vehicle function based on the determination of whether the location of the vehicle matches the predetermined location includes always performing the vehicle function when determined that the vehicle is not at the predetermined location.

4. A keyless function method for a vehicle, comprising:

receiving an actuation signal from a portable device for performing a vehicle function;

determining a location of the vehicle; and

selectively performing the vehicle function when the actuation signal is received based on the determined location, wherein selectively performing the vehicle function based on the location includes;

determining whether the location of the vehicle matches a predetermined location, and

performing the vehicle function is based on the determination of whether the location of the vehicle matches the predetermined location, and

wherein performing the vehicle function based on the determination of whether the location of the vehicle matches the predetermined location occurs only when an inhibit mode is on;

otherwise, the vehicle function is performed regardless of whether the location of the vehicle matches the predetermined location.

13. A method for performing a vehicle function from a remote portable device based a vehicle location and a portable device location, comprising:

receiving an actuation signal from a portable device for performing a vehicle function;

determining whether the vehicle location matches a predetermined location;

determining whether the portable device location indicates that the portable device is less than a predetermined distance from the vehicle;

performing the vehicle function if one of;

the vehicle location does not match the predetermined location, or both the vehicle location matches the predetermined location and the portable device location indicates that the portable device is less than the predetermined distance from the vehicle; and

inhibiting the vehicle function if the vehicle location matches the predetermined location and the portable device location indicates that the portable device is not less than the predetermined distance.

15. The method of claim 13 wherein the vehicle function is powered opening of a closure of the vehicle.

14. A method for performing a vehicle function from a remote portable device based a vehicle location and a portable device location, comprising:

receiving an actuation signal from a portable device for performing a vehicle function;

determining whether the vehicle location matches a predetermined location;

determining whether the portable device location indicates that the portable device is less than a predetermined distance from the vehicle;

performing the vehicle function if one of;

the vehicle location does not match the predetermined location, or both the vehicle location matches the predetermined location and the portable device location indicates that the portable device is less than the predetermined distance from the vehicle;

inhibiting the vehicle function if the vehicle location matches the predetermined location and the portable device location indicates that the portable device is not less than the predetermined distance; and

providing an inhibit mode switch on the vehicle, wherein inhibiting the vehicle function occurs only when the inhibit mode switch is in an ON position, otherwise performing the vehicle function occurs regardless of whether the vehicle is at the predetermined location and regardless of whether the portable device location indicates that the portable device is less than the predetermined distance from the vehicle.
