Abstract

Methods and apparatus, including computer program products, implementing and using techniques for determining route alternatives from a starting point to an ending destination for a vehicle, based at least in part on radio signal strength and availability. An input defining a starting point and an ending destination is received. A user input of a radio station preference is received. One or more route alternatives between the starting point and the ending destination are determined based on global positioning system data, the received radio station preference, and information on radio signal strength and availability.

Claims

1. A method for determining route alternatives from a starting point to an ending destination for a vehicle, based at least in part on radio signal strength and availability, comprising:

receiving a user input defining a starting point and an ending destination;

receiving a user input of a radio station preference; and

determining one or more route alternatives between the starting point and the ending destination based on global positioning system data, the received radio station preference, and information on radio signal strength and availability.

2. The method of claim 1, further comprising:

presenting the one or more route alternatives to the user; and

receiving a selection of a route alternative from the user.

3. The method of claim 1, wherein receiving a user input of a radio station preference includes:

receiving one or more of;

an identification of a specific radio station, an identification of a specific genre, an identification of a combination of radio stations, and an identification of a combination of genres.

4. The method of claim 1, wherein receiving a user input of a radio station preference includes:

receiving a user input pre-specifying one or more preferred radio stations for a given geographical region.

5. The method of claim 4, wherein determining one or more route alternatives includes:

determining one or more route alternatives between the starting point and the ending destination based on global positioning system data, the pre-specified received one or more radio stations, and information on radio signal strength and availability for the pre-specified one or more radio stations.

6. The method of claim 1, further comprising:

receiving a user input indicating the importance of the radio station preferences in relation to a fastest route between the starting point and the ending destination.

7. The method of claim 1, further comprising:

determining, while being en route between the starting point and the ending location, whether the radio station coverage is less than acceptable on the selected route.

8. The method of claim 7 further comprising:

selecting a different route in response to determining that the radio station coverage is less than acceptable on the selected route, wherein the different route has been determined to be acceptable based on the radio station coverage information.

9. The method of claim 7, further comprising:

providing an alert to the user in response to determining that the radio station coverage is less than acceptable on the selected route, wherein the different route has been determined to be acceptable based on the radio station coverage information.

10. The method of claim 1 further comprising:

continuously receiving a stream of radio signal strength and availability while being en route between the starting point and the ending destination.

11. The method of claim 1 further comprising:

periodically receiving radio signal strength and availability information.

12. A method for determining route alternatives for a driver of a vehicle, based at least in part on radio signal strength and availability, comprising:

receiving a user input of a radio station preference;

identifying a current location of the vehicle;

determining one or more route alternatives based on global positioning system data, the received radio station preference, and information on radio signal strength and availability, wherein each route alternative includes a reception quality indication for the radio station preference; and

presenting the one or more route alternatives to the driver.

13. A route determination device, operable to determine route alternatives from a starting point to an ending destination for a vehicle, based at least in part on radio signal strength and availability, comprising:

means for receiving a user input defining a starting point and an ending destination;

means for receiving a user input of a radio station preference; and

means for determining one or more route alternatives between the starting point and the ending destination based on global positioning system data, the received radio station preference, and information on radio signal strength and availability.

14. The device of claim 13, further comprising:

means for presenting the one or more route alternatives to the user; and

means for receiving a selection of a route alternative from the user.

15. The device of claim 13, wherein the means for receiving a user input of a radio station preference includes:

means for receiving one or more of;

an identification of a specific radio station, an identification of a specific genre, an identification of a combination of radio stations, and an identification of a combination of genres.

16. The device of claim 13, wherein the means for receiving a user input of a radio station preference includes:

means for receiving a user input pre-specifying one or more preferred radio stations for a given geographical region.

17. The device of claim 16, wherein the means for determining one or more route alternatives includes:

means for determining one or more route alternatives between the starting point and the ending destination based on global positioning system data, the pre-specified received one or more radio stations, and information on radio signal strength and availability for the pre-specified one or more radio stations.

18. The device of claim 13, further comprising:

means for receiving a user input indicating the importance of the radio station preferences in relation to a fastest route between the starting point and the ending destination.

19. The device of claim 13, further comprising:

means for determining, while being en route between the starting point and the ending location, whether the radio station coverage is less than acceptable on the selected route.

20. The device of claim 19 further comprising:

means for selecting a different route in response to determining that the radio station coverage is less than acceptable on the selected route, wherein the different route has been determined to be acceptable based on the radio station coverage information.

21. The device of claim 19, further comprising:

means for providing an alert to the user in response to determining that the radio station coverage is less than acceptable on the selected route, wherein the different route has been determined to be acceptable based on the radio station coverage information.

22. The device of claim 13 further comprising:

means for continuously receiving a stream of radio signal strength and availability while being en route between the starting point and the ending destination.

23. The device of claim 13 further comprising:

means for periodically receiving radio signal strength and availability information.

24. A route determination device, operable to determine route alternatives for a driver of a vehicle, based at least in part on radio signal strength and availability, comprising:

means for receiving a user input of a radio station preference;

means for identifying a current location of the vehicle;

means for determining one or more route alternatives based on global positioning system data, the received radio station preference, and information on radio signal strength and availability, wherein each route alternative includes a reception quality indication for the radio station preference; and

means for presenting the one or more route alternatives to the driver.
