It should be noted that the communication mode of vehicle and remote server can also be WIFI, bluetooth etc., the present embodiment exists
This is without limiting.
Certainly, in practical applications, can also judge whether detected outside rear-view mirror is normal using neural network, specifically
For the controller is also used to the voice signal being sent to the remote server；The remote server, for leading to
It crosses neural network and the change curve that analysis obtains voice signal is carried out to the voice signal, and judge to be detected according to change curve
Whether normal survey outside rear-view mirror.
When practical application, the voice signal generated when can obtain multiple groups outside rear-view mirror regular event utilizes multiple groups sound
Signal trains neural network, the neural network after being trained, since to have obtained outside rear-view mirror normal for the neural network after training
The change curve feature of voice signal when work, therefore, the neural network after training can be according to the variation of input audio signal
Curvilinear characteristic judges whether outside rear-view mirror is normal.When controller receives the voice signal of microphone module transmission, by the sound
Sound signal is sent to remote server, by remote server by the neural network after voice signal input training, obtains sound letter
Number change curve feature, training after neural network according to change curve feature judge be detected outside rear-view mirror it is whether normal.
In order to improve the accuracy of judging result, microphone module can be obtained repeatedly when detected outside rear-view mirror acts
Voice signal, and the voice signal generated when acting every time is sent to controller, the sound repeatedly obtained is believed by controller
It number is averaged as final voice signal, is being compared according to final voice signal with reference voice signal, then basis
Comparison result judges whether detected outside rear-view mirror is normal, improves the accuracy of judging result.
Generated voice signal is different when due to outside rear-view mirror vertically-acting and horizontal balance, reference voice letter
Number it is divided into corresponding voice signal when corresponding voice signal and horizontal balance when outside rear-view mirror vertically-acting.Based on this, this reality
It applies example and can use the voice signal generated when outside rear-view mirror vertically-acting and detected, generation when also can use horizontal balance
Voice signal detected.
In some embodiments, when the action command is that vertically-acting instructs, the microphone module, for obtaining
The first voice signal when the detected outside rear-view mirror vertically-acting；The controller, for receiving the microphone module
The first voice signal sent, first voice signal is compared with the first reference voice signal being obtained ahead of time, root
Judge whether the detected outside rear-view mirror is normal according to comparison result.
In the present embodiment, the voice signal generated when being detected outside rear-view mirror vertically-acting is the first voice signal, corresponding
Reference voice signal be the first reference voice signal.Since vertically-acting instruction is sent by controller, controller
When receiving the voice signal that microphone module is sent, it can be determined that the voice signal is the first voice signal, then by first
Voice signal is compared with the first reference voice signal, if two voice signal matchings, show to be detected outside rear-view mirror
It is working properly.If two voice signals mismatch, show that the voice signal generated when being detected outside rear-view mirror vertically-acting is different
Often, detected outside rear-view mirror is characterized to go wrong.Wherein, matching can be the first voice signal and the first reference voice signal
Amplitude difference and/or frequency difference are within a preset range；Mismatch can be the first voice signal and the first reference voice signal
Amplitude difference and/or frequency difference be more than preset range.
It is understood that in order to guarantee that the first voice signal that controller is compared is to be detected outside rear-view mirror vertically to move
As when the voice signal that generates, controller before comparison, can screen to be located at from the first voice signal and be detected outer backsight
Mirror vertically-acting start time, then controller was by the first sound piece to the first fragment of sound signal stopped between action moment
Break signal is compared with the first reference voice signal.
It is usually to be acted immediately in the vertically-acting instruction for receiving controller transmission due to being detected outside rear-view mirror,
Therefore, at the time of detected outside rear-view mirror vertically-acting start time is considered as controller transmission vertically-acting instruction.Similarly,
When being detected the halt instruction that outside rear-view mirror reception controller is sent, therefore the movement of stopping immediately being detected outside rear-view mirror and stops
At the time of action moment is considered as controller transmission halt instruction, since vertically-acting is instructed with halt instruction by controller
It sends, at the time of controller can recorde itself transmission above-mentioned two instruction.
Therefore, controller can be filtered out from received first voice signal of institute according to two moment of self record
The first fragment of sound signal between above-mentioned two moment, so that controller is by the first fragment of sound signal and the first reference voice
Signal is compared, and improves the accuracy of detection.
In order to improve the accuracy of judging result, microphone module can repeatedly obtain detected outside rear-view mirror vertically-acting
When voice signal, and the voice signal that by each movement when generates is sent to controller, the sound that will repeatedly be obtained by controller
Sound signal is averaged as the first voice signal, is being compared according to first voice signal with the first reference voice signal
Compared with, it is then whether normal according to the detected outside rear-view mirror of comparison result judgement, improve the accuracy of judging result.
In some embodiments, when the action command is that horizontal balance instructs, the microphone module, for obtaining
Second sound signal when the detected outside rear-view mirror horizontal balance；The controller, for receiving the microphone module
The second sound signal is compared, root by the second sound signal of transmission with the second reference voice signal being obtained ahead of time
Judge whether the detected outside rear-view mirror is normal according to comparison result.
In the present embodiment, the voice signal generated when being detected outside rear-view mirror horizontal balance is second sound signal, corresponding
Reference voice signal be the second reference voice signal.Since horizontal balance instruction is sent by controller, controller
When receiving the voice signal that microphone module is sent, it can be determined that the voice signal is second sound signal, then by second
Voice signal is compared with the second reference voice signal, if two voice signal matchings, show to be detected outside rear-view mirror
It is working properly.If two voice signals mismatch, show that the voice signal generated when being detected outside rear-view mirror vertically-acting is different
Often, detected outside rear-view mirror is characterized to go wrong.Wherein, matching can be second sound signal and the second reference voice signal
Amplitude difference and/or frequency difference are within a preset range；Mismatch can be second sound signal and the second reference voice signal
Amplitude difference and/or frequency difference be more than preset range.
It is understood that in order to guarantee that the second sound signal that controller is compared is to be detected outside rear-view mirror press horizontal mobile
As when the voice signal that generates, controller before comparison, can screen to be located at from second sound signal and be detected outer backsight
Mirror horizontal balance start time, then controller was by rising tone tablet to the first fragment of sound signal stopped between action moment
Break signal is compared with the second reference voice signal.
It is usually to be acted immediately in the horizontal balance instruction for receiving controller transmission due to being detected outside rear-view mirror,
Therefore, at the time of detected outside rear-view mirror horizontal balance start time is considered as controller transmission horizontal balance instruction.Similarly,
When being detected the halt instruction that outside rear-view mirror reception controller is sent, therefore the movement of stopping immediately being detected outside rear-view mirror and stops
At the time of action moment is considered as controller transmission halt instruction, since horizontal balance is instructed with halt instruction by controller
It sends, at the time of controller can recorde itself transmission above-mentioned two instruction.
Therefore, controller can be filtered out from the received second sound signal of institute according to two moment of self record
Second sound piece break signal between above-mentioned two moment, so that controller is by second sound piece break signal and the second reference voice
Signal is compared, and improves the accuracy of detection.
In order to improve the accuracy of judging result, microphone module can repeatedly obtain detected outside rear-view mirror horizontal balance
When voice signal, and the voice signal that by each movement when generates is sent to controller, the sound that will repeatedly be obtained by controller
Sound signal is averaged as second sound signal, is compared according to the second sound signal and the second reference voice signal
Compared with, it is then whether normal according to the detected outside rear-view mirror of comparison result judgement, improve the accuracy of judging result.
It should be noted that controller can use a kind of voice signal judge to be detected outside rear-view mirror it is whether normal, when
Can also so judge whether detected outside rear-view mirror is normal, improves the accuracy of judging result according to two kinds of voice signals.Specifically
Vertically-acting instruction, horizontal balance instruction are sent to detected outside rear-view mirror respectively for controller, is distinguished by microphone module
Obtain second sound signal when the first voice signal and horizontal balance when being detected outside rear-view mirror vertically-acting, controller
The first voice signal is compared with the first reference voice signal, second sound signal with the second reference voice signal respectively and
Judgement, two groups of judging result is verified, to improve the accuracy of judging result.
It is understood that when obtaining voice signal when being detected outside rear-view mirror movement using microphone module, unavoidably
Other components reasons for its use voice signals can be acquired, to guarantee that controller when progress voice signal compares, is compared
Voice signal is the voice signal for being detected outside rear-view mirror movement, improves subsequent judging result, the present embodiment is in controller to sound
Before sound signal is compared, be filtered background noise signal except making an uproar.
In some embodiments, the microphone module is also used to be obtained ahead of time the detected outside rear-view mirror and does not move
Background noise signal when making；The voice signal is being compared by the controller with the reference voice signal being obtained ahead of time
Before, it is also used to subtract the background noise signal from the voice signal.
Wherein, the voice signal that background noise signal can generate for other components of vehicle, naturally it is also possible to be other
The voice signal that object generates.
In the present embodiment, background noise signal can be obtained ahead of time, and be stored in controller, carry out sound in controller
Before signal compares, the voice signal that microphone module is sent is subtracted into background noise signal, guarantees that controller is utilizing sound
When signal compares, the voice signal compared is voice signal when outside rear-view mirror acts, and avoids background noise signal to final
The influence of judging result improves the accuracy of detection outside rear-view mirror.
After controller subtracts background sound from voice signal, when noiseless sound signal, illustrate to be detected outside rear-view mirror not
It can be operating normally, show to be detected outside rear-view mirror complete failure.For this situation, when judgement is detected outside rear-view mirror complete failure
When, warning reminding is carried out to driver, so that driver in time overhauls outside rear-view mirror.Specifically, when controller is sentenced
Disconnected detected outside rear-view mirror complete failure, control warning piece alarm.Wherein, warning piece can be buzzer, light-emitting diodes
Pipe or voice broadcasting system etc..
In order to guarantee to remove background noise signal, in some embodiments, the microphone module as much as possible
Be obtained ahead of time the detected outside rear-view mirror it is not operating when background noise signal, specifically: the microphone module is more in advance
It is secondary obtain the detected outside rear-view mirror it is not operating when background noise signal, and the background noise signal repeatedly obtained is sent
To the controller；The background noise signal repeatedly obtained is averaged as final background noise signal by the controller；
The controller subtracts the background noise signal from the voice signal, specifically: the controller is believed from the sound
The final background noise signal is subtracted in number.
In the present embodiment, final background noise signal can be stored in controller, voice signal is carried out in controller
When comparing, final background noise signal is subtracted from voice signal and obtains final voice signal, so that controller is by final sound
Signal is compared with reference voice signal, by removing background noise signal, improves the accuracy of judging result.
The method of specific removal background noise signal can be according to the feature of background noise signal, using different filtering sides
Method is eliminated.For example, background noise signal is rendered as high-frequency characteristic, low-pass filtering method can be used, by background sound message
