Voice indicating distance adjusting method for global positioning system, involves searching corresponding indicating distance from integrated table based on current driving speed, where indicating distance is updated and registered

摘要

The method involves receiving and decoding global positioning system satellite signals. A speed parameter is obtained from the global positioning system satellite signals, and an evaluation is performed based on the speed parameter. The current driving speed is obtained. Corresponding indicating distance is searched from integrated table based on the current driving speed. The indicating distance is updated and registered.
