If E. vehicle window status signal display vehicle window state is in opening, it is determined that open second microphone simultaneously;
F. according to determination result obtained in B-E step, engine speed, speed, air conditioner wind speed any one Higher than threshold value or in the case of have vehicle window to be in opening, open the first microphone and second microphone simultaneously;Starting In the case that machine rotating speed, speed, air conditioner wind speed are below threshold value and vehicle window Close All, only open the first microphone;
If G. open the first microphone and second microphone simultaneously, i.e. by software algorithm to the first microphone and the second wheat The voice that gram wind obtains carries out noise reduction process, improves the discrimination obtaining voice further.
The controller of the present invention obtains vehicle motor rotating speed and speed information identification internal car noise ring by CAN network Border, by software logic algorithm, utilizes the information such as vehicle motor rotating speed, speed, window locations, air conditioner wind speed to judge sound in car Sound environment, activates different microphones for different acoustic environments.According to different operating environments, by different pickup moulds Formula obtains driver's phonetic order, improves the accuracy rate identifying.
Brief description
Fig. 1 is present configuration schematic diagram;
Fig. 2 is logical schematic of the present invention;
Detailed description of the invention
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, it is simple to is well understood to this Bright, but they do not constitute restriction to the present invention.
As it is shown in figure 1, the invention provides a kind of voice picking up system, it is characterised in that:It includes controller, controller Be electrically connected with the first microphone and second microphone, controller by CAN receive vehicle speed sensor transmission GES, The engine rotational speed signal of engine speed sensor transmission, the air conditioner wind speed signal of air conditioner wind speed sensor passes, vehicle window shape The vehicle window status signal of state sensor passes;Controller, for according to outside input control command and receive above-mentioned respectively Car status information control the first microphone and the open and-shut mode of second microphone.
Described controller includes:Control command determining unit, if being configured to receive the control life of the first microphone Order then determines opens the first microphone;Speed determining unit, if being configured to GES to be more than internal predetermined threshold, then really Determine to open the first microphone and second microphone simultaneously;Engine speed determining unit, if being configured to engine speed letter Number more than internal predetermined threshold, it is determined that open the first microphone and second microphone simultaneously;Air conditioner wind speed determining unit, is joined If be set to air conditioner wind speed signal more than internal predetermined threshold, it is determined that open the first microphone and second microphone simultaneously;Car Window status determining unit, if being configured to vehicle window status signal display vehicle window state to be in opening, it is determined that open simultaneously Open the first microphone and second microphone.
The invention provides a kind of voice pick-up method, it is characterised in that comprise the following steps:
A., after controller receives the control command opening the first microphone, confirm to open the first microphone;
If B. GES is more than internal predetermined threshold, it is determined that open second microphone simultaneously;
If C. engine rotational speed signal is more than internal predetermined threshold, it is determined that open second microphone simultaneously;
If D. air conditioner wind speed signal is more than internal predetermined threshold, it is determined that open second microphone simultaneously;
If E. vehicle window status signal display vehicle window state is in opening, it is determined that open second microphone simultaneously;
F. according to determination result obtained in B-E step, engine speed, speed, air conditioner wind speed any one Higher than threshold value or in the case of have vehicle window to be in opening, open the first microphone and second microphone simultaneously;Starting In the case that machine rotating speed, speed, air conditioner wind speed are below threshold value and vehicle window Close All, only open the first microphone;
If G. open the first microphone and second microphone simultaneously, i.e. by software algorithm to the first microphone and the second wheat The voice that gram wind obtains carries out noise reduction process, improves the discrimination obtaining voice further.The present invention mainly has two kinds of pickups Pattern:Noise reduction mode and without noise reduction mode.During use, by software logic algorithm, utilize vehicle motor rotating speed, car The information such as speed, window locations, air conditioner wind speed judge acoustic environment in car, activate different pickup patterns and have obtained optimal voice Recognition effect.Pattern 2, including at least once two kinds of pickup patterns, follow-up can be finely divided by system as required.
