Abstract

A method of dynamically adjusting a voice suggested distance for global positioning system (GPS) is provided. The method comprises receiving and decoding a GPS signal first by an electronic device, and then obtaining a speed parameter from the GPS signal. Then, a current driving speed is generated by calculating the obtained speed parameter, and a corresponding suggested distance is sought from a build-in table stored in the electronic device based on the current driving speed. Finally, the suggested distance is updated and registered temporarily. Accordingly, the present invention provides a more human GPS navigation function.

Claims

1. A method of dynamically adjusting a voice suggested distance for global positioning system (GPS) suitable for adjusting a suggested distance to a preset location based on a current driving speed, the method comprising:

receiving and decoding a GPS satellite signal;

obtaining a speed parameter from the decoded GPS satellite signal;

performing a calculation based on the speed parameter;

obtaining a current driving speed;

searching for the corresponding suggested distance from a build-in table based on the current driving speed; and

updating and registering the suggested distance.

2. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, further comprising making a sound of a voice suggested and/or a warning beep after approaching the suggested distance.

3. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the step of receiving and decoding the GPS satellite signal comprises:

receiving the GPS satellite signal;

amplifying the GPS satellite signal;

filtering a noise from the GPS satellite signal; and

decoding the filtered GPS satellite signal.

4. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the suggested distance in the build-in table is preconfigured in a production line.

5. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the suggested distance in the build-in table is configured by a user.

6. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the speed parameter comprises a Recommended Minimum Specific (RMC) recommended by the GPS.

7. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the speed parameter comprises a relative displacement direction and a Vector To Ground (VTG).

8. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the GPS satellite signal comprises National Marine Electronics Association (NMEA) communication protocol data.

9. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the preset location comprises a turning point en route.

10. The method of dynamically adjusting the voice suggested distance for GPS of claim 1, wherein the preset location comprises a destination.
