Abstract

The phonetic prompt method of navigation instrument includes: for the navigation instrument to calculate the current position and running speed based on received GPS signal and read out the map data corresponding to the current position; to calculate the specific location of the current pns in the navigation path and show in the touch screen; to calculate the distance from the current position to the next prompt point; to look out the corresponding prompt phone and calculate the time span essential for broadcasting the prompt point; and to calculate the time to start the broadcasting based the fore said data so as to make it possible to end the broadcast before reaching the next prompt point.

Description

technical field [0001] The invention relates to a voice prompt method for a navigator. Background technique [0002] Existing navigators have a function of setting user options so that the navigator can find a guiding route to a destination desired by the user when performing route finding. User options may include "highway priority", "distance priority" and "no toll priority", etc., from which the user can select the desired option to find the ideal route to the destination. [0003] Voice navigation is a must-have feature for navigators. In the prior art, when the vehicle reaches a certain (or more than one) set distance before the next prompt point, the system will prompt how to go to the next prompt point, for example, at a distance of 300 meters from the next prompt point , the navigator will prompt: "About 300 meters ahead, turn right", which can better guide the driver's driving. However, with the continuous development of the city, limited by geographical conditio...
