Navigation system and navigation system voice prompt method

Abstract

The invention provides a navigation system and a navigation system voice prompt method thereof. The navigation system comprises a navigation module, a user interface control module and a map data management module; wherein, the navigation module comprises a navigation control module, a self-position detection module, a road type judgment module and a voice prompt module; wherein, the road type judgment module receives vehicle positioning information from the self-position detection module, obtains map data from the map data management module and judges the type of the road in which the vehicle is located; the voice prompt module selects different languages to prompt distance according to different road types and carries out voice prompt when the value of the specific position of the driving distance of the vehicle is less than the corresponding voice prompt distance threshold value of the current road type. By selecting different voice to remind distance threshold value according to the type of the located road of the user, the navigation system gives the user sufficient time to make corresponding preparations after hearing the voice prompt without burdening the system and affecting the function of the navigation system.

Description

technical field [0001] The invention belongs to the technical field of navigation, in particular to a navigation system and a navigation system voice prompt method. Background technique [0002] At present, the global positioning system (Global Positioning System, GPS) for vehicles is one of the important application directions of GPS navigation. The GPS antenna of the car GPS navigation system receives the data information transmitted by at least 3 of the 24 GPS satellites around the earth, combined with the electronic map stored in the car navigation terminal, the position coordinates determined by the GPS satellite signal and this match to determine the exact position of the navigation object in the electronic map. The user driving the vehicle can let the computer select the driving path while driving, and use this as the direction guide, so as to reach the destination correctly and quickly. [0003] figure 1 It is a structural diagram of a car navigation system in the...
