Embodiment 1

[0035] (Embodiment 1, navigation device)

[0036] Such as figure 1 , the navigation device of the present invention is installed on the vehicle when in use, and the navigation device includes: CPU unit 1, GPS receiver 2, map database storage unit 3, program database storage unit 4, voice output device 5, voice database storage unit 6 and display unit 7 . The display screen of the display unit 7 is a touch screen. The GPS receiver 2 is electrically connected to the CPU unit 1 bidirectionally; the CPU unit 1 is electrically connected to the map database storage unit 3, the program database storage unit 4, the voice database storage unit 6 and the display unit 7 respectively; the voice signal output terminal of the CPU unit 1 Connect the voice signal input end of the voice output device 5.

[0037] The map database storage unit 3 stores an electronic map database, a complex intersection model library and a simple intersection model. The complex intersection model library is c...

Embodiment 2

[0050] (Embodiment 2, navigation device)

[0051] The navigation device of this embodiment is obtained after refinement of relevant components on the basis of the navigation device obtained in Embodiment 1. That is, each keyword data of the keyword database stored in the speech database storage unit 6 is recording data. The voice module stored in the program database storage unit 4 is a voice guide module. When the CPU unit 1 runs the voice guide module, under the control of the module, each piece of recorded data is sent to the voice output device 5 connected to it in turn.

Embodiment 3

[0052] (Embodiment 3, navigation device)

[0053] The navigation device of this embodiment is obtained after refinement of relevant components on the basis of the navigation device obtained in Embodiment 1. Details are as follows:

[0054] The stored voice database of the voice database storage unit 6 also includes a Chinese single-character voice database; the Chinese single-character voice database in the Chinese single-character voice database includes commonly used Chinese single-character characters; each keyword data includes several Chinese single-character voice data in the Chinese single-character voice database A piece of code including the address code. The voice module stored in the program database storage unit 4 is a voice matching module; when the CPU unit 1 runs the voice matching module, under the control of the module, according to each Chinese single-character voice data contained in a group of keyword data called out The address code of the address code t...

Abstract

The invention relates to a navigation device that can realize voice navigation to complex crossings, and a working method thereof. A map data base storage unit of the navigation device is used for storing models of each complex crossing, and a voice database storage unit is used for storing a voice database that contains a keyword database and a database of voice data address codes that consists of each address code; a group of keywords that are corresponding to each address code group represent speeches of all driving actions that are orderly implemented when driving through a corresponding complex crossing; the address code of each address code group is associated with a master serial number of the corresponding model of the complex crossing. When the navigation device implements real-time navigation according to a guidance path, a CPU unit reads the model number of the closest complex crossing in front, obtains a route for driving through the crossing according to the guidance path, and the master serial number of the passed crossing, thus displaying the crossing pattern by a display screen and simultaneously presenting indication voice by a voice output device.

Description

technical field [0001] The invention relates to a navigation device capable of performing voice navigation on complex intersections and a working method thereof. Background technique [0002] Existing navigation devices have a user option function, so that when performing a route finding task, the navigation device can determine a guiding route from a starting point to a destination that meets the user's expectations. User options may include "major road priority", "distance priority", "no toll priority" and "highway priority", etc., from which the user can select the desired option to determine the guided route to the destination that meets the user's expectations. [0003] Voice guidance is a mandatory function of the navigation device. The voice navigation system in the prior art only has simple voice prompt functions such as "turn left" and "turn right", which are not enough for complex intersections. For example, at the intersection of the upper viaduct, there are ofte...
