Abstract
The invention relates to an automotive navigation control system and an automotive navigation control method, in particular to automotive voice navigation. In automotive navigation equipment, a voice acquisition module acquires voice signal input externally, and is connected with a voice processing module used for correspondingly processing the acquired voice signals and converting the acquired voice signals into system recognizable signals; a voice recognition module is connected with a keyword module; the keyword module pre-stores related keyword information and is used for extracting and recognizing the voice signals according to the keyword information; recognition results of the voice recognition module are output to a control module; and the control module controls to output navigation signals. Corresponding control signals are acquired by analyzing the acquired voice signals to control the operation of the navigation system, the acquired voice signals are converted into electric signals for transmission, navigation information setting of vehicles in different running states is achieved, the navigation information is set in a voice mode, and the driving safety is improved.
Description
Technical field
The present invention relates to auto navigation control system and method, be specifically related to the automobile Voice Navigation.
Background technology
In the prior art, manual mode typing related content is generally adopted in the information acquisition of automobile navigation instrument, again by navigation output navigation route information.
For example, navigating instrument adopts touch-screen, and the user is through handwriting mode input corresponding navigation information, and this navigation information comprises the destination information, routing information of vehicle ' etc.Therefore; Existing navigating instrument needs the user before navigating, to be provided with in advance; If there are not other cars that possess the input relevant information to take advantage of personnel on the vehicle, then human pilot must manually be provided with corresponding navigation information under the vehicle lay-off state, after navigation setting is accomplished, need change navigation information as if the user; Then must carry out brake operating, under the vehicle lay-off state, manually be provided with.
In the prior art, the user is through manual mode setting or change navigation information, and its operation is more loaded down with trivial details, and promptly convinent car is superior has the other staff can implementation and operation, both dangerously also under vehicle running state is difficult to operate owing to vehicle jolts.
Summary of the invention
Primary and foremost purpose of the present invention provides a kind of auto-navigation system, possesses setting and change that the phonetic entry mode is carried out navigation information.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
A kind of auto-navigation system is characterized in that: be provided with in the car navigation device:
Voice acquisition module, voice acquisition module is gathered the voice signal of extraneous input;
Speech processing module is connected with voice acquisition module, is used for the voice signal that collects is handled and the discernible signal of the system that converts to accordingly;
Sound identification module is connected with the keyword module, and the relevant key word information of pre-stored is used for according to key word information voice signal being extracted and discerning in the keyword module;
The result that sound identification module identifies exports control module to, control module control output navigation signal.
In conjunction with said system, a further object of the present invention just provides a kind of control method of auto-navigation system.The scheme that is adopted is:
Voice acquisition module is gathered the voice signal of extraneous input;
Speech processing module is connected with voice acquisition module, is used for the voice signal that collects is handled and the discernible signal of the system that converts to accordingly;
Sound identification module is connected with the keyword module, and the relevant key word information of pre-stored is used for according to key word information voice signal being extracted and discerning in the keyword module;
The result that sound identification module identifies exports control module to, the operation of control module control output navigation signal control navigational system.
The present invention proposes a kind of auto-navigation system and control method; Through in existing car navigation device, voice module being set; Voice module is gathered the voice signal of extraneous input, and the voice signal analysis of gathering is obtained the operation of control signal corresponding with the control navigational system.Auto-navigation system comprises voice acquisition module, speech processing module, keyword module, voice extraction module, sound identification module and control module; Wherein, Voice signal with the human body input; Comprise auto navigation signal, electronic chart search signal etc., and the voice signal that collects is transformed into electric signal transmits.
The present invention has satisfied the navigation information setting of vehicle under different transport conditions; Voice module is set in navigator; Adopt voice mode that navigation information is provided with, help improving traffic safety, solved the suffered all restrictions of navigation information manually are set merely.
Description of drawings
Fig. 1, the 2nd, the theory diagram of two kinds of embodiments of the present invention.
Embodiment
Embodiment 1
Auto-navigation system comprises voice module, specifically:
The result that sound identification module 50 identifies exports control module 60 to, control module 60 control output navigation signals.
There are two kinds of basic comprisings in system specifically of the present invention, and the first comprises voice extraction module 40, and is as shown in Figure 1; It two is not comprise voice extraction module 40, and is as shown in Figure 2.
In conjunction with shown in Figure 1, be provided with voice extraction module 40 between described speech processing module 20 and the sound identification module 50.
For example, the relevant information that identifies in the interval voice signal of keyword " destination " position surrounding time according to keyword module 30 is " Zhongshan Road ", and confirms that navigation " destination " is " Zhongshan Road " in this voice signal.
For example, the keyword signal " destination " in voice extraction module 40 recognition of speech signals obtains the position at keyword signal " destination " place, and extracts M second and the interior signal of back N time interval second before keyword signal " destination " position.As preferred embodiment, the value of the value of M smaller or equal to N can be set, make that near other information keyword signal position can be extracted accurately.Certainly, the value of M and N also can be provided with according to attribute of user.
Described keyword module 30 is connected with voice extraction module 40 with speech processing module 50.
Navigation signals are exported in control module 60 controls, and with voice mode the user are pointed out, and the request user confirms it.
Need to prove; In the present invention; Through keyword module 30 being set and in keyword module 30, key word information being set, extract near the voice signal the key word information position and the voice signal that extracts discerned, avoided the whole voice that obtain are discerned; Improve the precision of identification, and alleviated the burden that system carries out speech recognition.
Embodiment 2
The control method of auto-navigation system comprises:
The result that sound identification module 50 identifies exports control module 60 to, the operation of control module 60 control output navigation signal control navigational system.
