Abstract:
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 of a mobile device, 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 the current driving speed; providing a built-in table with a relationship between a plurality of driving speeds and a plurality of distances stored therein; according to the relationship between the driving speeds and the distances stored in the built-in table, searching for the corresponding suggested distance among the distances based on the current driving speed; updating and registering the suggested distance; and making a sound of a voice suggested and/or a warning beep when the mobile device approaching the suggested distance.
