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;
