Embodiment Construction

[0031] 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.

[0032] The idea of ​​the present invention is that when the user's vehicle travels to a certain distance from a specific location such as a fork in the road, a turn, a destination, etc., and the distance changes, several voice prompts are issued, and the volume of each prompt is gradually increased or the speech speed is gradually increased. Get faster, detect the vehicle speed in real time, and dynamically adjust the distance threshold for triggering prompts. In addition, the present invention sends out different sound prompts as the distance changes, and is not limited to ways such as gradually i...

Abstract

The invention provides a navigation system, a navigation system voice prompt device and a 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 voice control module and a voice prompt module; the voice control module receives the specific position information of the driving distance of the vehicle transmitted from the navigation control module and enables the voice prompt module to send out a plurality of different types of voice prompt through the user interface control module according to the distance of the specific position of the driving distance of the vehicle. The navigation system can send out different types of voice prompt according to the distance of the specific position of the driving distance of the vehicle, thus providing sufficient time for the user to make corresponding preparations after hearing the voice prompt.

Description

technical field [0001] The invention belongs to the technical field of navigation, and in particular relates to a navigation system, a navigation system voice prompt device and a 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 na...
