Abstract

A vehicle communication system ( 100 ) for facilitating control over a function of a vehicle ( 102 ) comprises a base station ( 104 ) positioned in the vehicle ( 102 ) and a mobile communication unit ( 122 ). The base station ( 104 ) comprises a first transmitter for transmitting a signal to the mobile communication unit and a first receiver for receiving a signal from the mobile communication unit ( 122 ). The base station ( 104 ) is configured to receive a first request from the mobile communication unit ( 122 ), wherein the first request seeks performance of a first vehicle function, determine a position of the mobile communication unit ( 122 ) relative to the vehicle ( 102 ), compare the position of the mobile communication unit ( 122 ) relative to the vehicle ( 102 ) to a first criteria, and facilitate performance of the first vehicle function if the position of the mobile communication unit ( 122 ) relative to the vehicle ( 102 ) satisfies the first criteria.

First claim

The invention claimed is:

1. A vehicle communication system for facilitating control over a function of a vehicle, the vehicle communication system comprising:
a base station positioned in the vehicle; and
a mobile communication unit;
the base station comprising a first transmitter for transmitting a signal to the mobile communication unit and a first receiver for receiving a signal from the mobile communication unit;
the base station configured to:
receive a first request from the mobile communication unit, wherein the first request seeks performance of a first vehicle function;
receive a second request from the mobile communication unit, wherein the second request seeks performance of a second vehicle function;
determine a position of the mobile communication unit relative to the vehicle;
compare the position of the mobile communication unit relative to the vehicle to a first criteria;
compare the position of the mobile communication unit relative to the vehicle to a second criteria;
facilitate performance of the first vehicle function if the position of the mobile communication unit relative to the vehicle satisfies the first criteria; and
facilitate performance of the second vehicle function if the position of the mobile communication unit relative to the vehicle satisfies the second criteria;
wherein the first criteria requires that the position be within a first distance from the vehicle, wherein the second criteria requires that the position be within a second distance from the vehicle, and wherein the first distance is greater than the second distance.

2. The vehicle communication system of claim 1 , wherein the base station is configured to determine the position of the mobile communication unit relative to the vehicle based on a time of flight method.

3. The vehicle communication system of claim 1 , wherein the first transmitter is an ultra-wideband transmitter and the first receiver is an ultra-wideband receiver.

4. The vehicle communication system of claim 1 , wherein the base station is configured to facilitate performance of the first vehicle function only if the position of the mobile communication unit satisfies the first criteria.

5. The vehicle communication system of claim 1 , wherein the first criteria requires that the position be less than or greater than a first distance from the vehicle.

6. The vehicle communication system of claim 1 , wherein the base station is configured to facilitate performance of the first vehicle function only if the position of the mobile communication unit satisfies the first criteria, and wherein and the base station is configured to facilitate performance of the second vehicle function only if the position of the mobile communication unit satisfies the second criteria.

7. The vehicle communication system of claim 1 , wherein the base station is configured to:
receive a third request from the mobile communication unit, wherein the third request seeks performance of a third vehicle function;
compare the position of the mobile communication unit relative to the vehicle to a third criteria; and
facilitate performance of the third vehicle function if the position of the mobile communication unit relative to the vehicle satisfies the third criteria.

8. The vehicle communication system of claim 7 , wherein the base station is configured to facilitate performance of the first vehicle function only if the position of the mobile communication unit satisfies the first criteria, and wherein and the base station is configured to facilitate performance of the second vehicle function only if the position of the mobile communication unit satisfies the second criteria, and wherein and the base station is configured to facilitate performance of the third vehicle function only if the position of the mobile communication unit satisfies the third criteria.

9. The vehicle communication system of claim 7 , wherein the first criteria requires that the position be within a first distance from the vehicle, wherein the second criteria requires that the position be within a second distance from the vehicle, and wherein the third criteria requires that the position be within a third distance from the vehicle, wherein the first distance is greater than the second distance, and wherein the second distance is greater than the third distance.

10. The vehicle communication system of claim 7 , wherein the third vehicle function comprises opening or closing an aperture of the vehicle.

11. The vehicle communication system of claim 1 , wherein the first vehicle function comprises locking an aperture of the vehicle.

12. The vehicle communication system of claim 1 , wherein the second vehicle function comprises starting an engine of the vehicle.

13. A vehicle comprising the vehicle communication system of claim 1 .

14. A method for facilitating control over a function of a vehicle, the method comprising:
providing a base station positioned in the vehicle and a mobile communication unit, the base station comprising a first transmitter for transmitting a signal and a first receiver for receiving a signal from the mobile communication unit;
receiving a first request from the mobile communication unit, wherein the first request seeks performance of a first vehicle function;
receiving a second request from the mobile communication unit, wherein the second request seeks performance of a second vehicle function;
determining a position of the mobile communication unit relative to the vehicle;
comparing the position of the mobile communication unit relative to the vehicle to a predetermined first criteria;
comparing the position of the mobile communication unit relative to the vehicle to a predetermined second criteria;
facilitating performance of the first request if the position of the mobile communication unit relative to the vehicle satisfies a first criteria; and
facilitating performance of the second request if the position of the mobile communication unit relative to the vehicle satisfies a second criteria;
wherein the first criteria requires that the position be within a first distance from the vehicle, wherein the second criteria requires that the position be within a second distance from the vehicle, and wherein the first distance is greater than the second distance.

15. The method of claim 14 , wherein determining the position of the mobile communication unit relative to the vehicle is based on a time of flight method, wherein the first transmitter is an ultra-wideband transmitter and the first receiver is an ultra-wideband receiver.

16. The method of claim 14 , further comprising:
receiving a third request from the mobile communication unit, wherein the third request seeks performance of a third vehicle function;
comparing the position of the mobile communication unit relative to the vehicle to a third criteria; and
facilitating performance of the third vehicle function if the position of the mobile communication unit relative to the vehicle satisfies the third criteria.
