Specific embodiment
The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments, convenient for this hair is well understood
It is bright, but they limiting the invention.
As shown in Figure 1, the present 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 received by CAN bus the speed signal that vehicle speed sensor transmits,
Air conditioner wind speed signal, the vehicle window shape of engine rotational speed signal, air conditioner wind speed sensor passes that engine speed sensor transmits
The vehicle window status signal of state sensor passes;Controller, for according to externally input control command and receiving above-mentioned each
The open and-shut mode of car status information control the first microphone and second microphone.
The controller includes: control command determination unit, if being configured to receive the control life of the first microphone
It enables and then determines the first microphone of unlatching;Speed determination unit, if being configured to speed signal greater than internal predetermined threshold, really
Fixed while the first microphone of unlatching and second microphone;Engine speed determination unit, if being configured to engine speed letter
Number it is greater than internal predetermined threshold, it is determined that while opening the first microphone and second microphone;Air conditioner wind speed determination unit is matched
If being set to air conditioner wind speed signal greater than internal predetermined threshold, it is determined that while opening the first microphone and second microphone;Vehicle
Window status determining unit, if being configured to vehicle window status signal shows that vehicle window state is in the open state, it is determined that open simultaneously
Open the first microphone and second microphone.
The present invention provides a kind of voice pick-up methods, it is characterised in that the following steps are included:
A. after controller receives the control command for opening the first microphone, the first microphone is opened in confirmation;
B. if speed signal is greater than internal predetermined threshold, it is determined that while opening second microphone;
C. if engine rotational speed signal is greater than internal predetermined threshold, it is determined that while opening second microphone;
D. if air conditioner wind speed signal is greater than internal predetermined threshold, it is determined that while opening second microphone;
E. if vehicle window status signal shows that vehicle window state is in the open state, it is determined that while opening second microphone;
