Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0027] The idea of ​​the present invention is to first determine the type of road the user is on, whether it is an expressway, an expressway or a general road section, and then set the distance threshold for triggering the voice prompt according to the normal driving speed of the above road section and in combination with the user's reaction time.

[0028] see figure 2 , is a block diagram of the navigation system of the present invention. The navigation system of the present invention mainly includes a navigation module, a user interface control module, and a map data management module. Wherein...

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...
