At present, an external microphone is arranged outside the existing vehicle, so that communication between personnel outside the vehicle and passengers in the vehicle and control of the vehicle by voice are realized. In order to achieve a good communication function, a microphone installed outside the vehicle needs to ensure that its pickup channel is not blocked or plugged. However, rain, snow, ice, soil, leaves and the like may cause shielding or blockage of the pickup hole 150 of the microphone when the vehicle is outside, affecting the microphone pickup function, and having a large probability of failure compared with the vehicle-outside microphone.

However, in the existing off-vehicle microphone, it is difficult to directly distinguish whether a jam occurs or not by naked eyes in a state of not being detached, and it is also impossible to determine whether a microphone malfunction occurs or not. In order to solve the problem that whether the microphone outside the vehicle fails or not cannot be identified in the prior art, referring to fig. 1 to 2, the invention provides an off-vehicle microphone failure identification device, a failure identification method and a vehicle.

The method for identifying the microphone faults outside the vehicle is applied to an identifying device for identifying the microphone faults outside the vehicle, and the identifying device for identifying the microphone faults outside the vehicle comprises a sound generating module 110 and a microphone module 120. The method for identifying the faults of the microphone outside the vehicle comprises the following steps:

step S100, controlling the sounding module 110 to output an audio signal with a corresponding audio size according to a preset audio range;

step 200, receiving the audio signal outside the vehicle detected by the microphone module 120, and determining the actual audio parameter of the audio signal outside the vehicle;

and step S300, determining a microphone fault when the actual audio parameters are out of the preset audio range.

In the embodiment of the present application, the sounding module 110 may be a vibrator, a sound box, other devices capable of emitting vibration or preset music, etc. and circuit components thereof, for converting audio signals into sound, so as to output audio signals with corresponding audio sizes to the outside of the vehicle according to a preset audio range; the microphone module 120 shown may be configured as a transducer, such as a microphone, for converting sound into an electrical signal and its circuit components for receiving interactive sounds, such as off-board human voice, ambient sound, etc. The illustrated sound emitting module 110 and microphone module 120 may be installed outside the vehicle and in other locations of the vehicle as the microphone assembly 100 of the off-vehicle microphone failure recognition device. In the embodiment of the present application, the microphone module 120 is configured to detect an audio signal outside the vehicle, specifically, may detect after the sound generating module 110 sends out the audio signal, so as to determine that a microphone fault exists when the detected actual audio parameter of the audio signal outside the vehicle is outside the preset audio range.

Alternatively, the preset audio range may be an audio parameter acquired by the microphone module and other microphone modules 100 outside the vehicle during the actual use and in the historical test data, and the preset audio range may be a parameter range, or may also be a dynamic value set according to the actual use environment, etc. In addition, according to practice, the sounding module 110 may be configured to output an audio signal corresponding to the audio frequency according to the preset audio frequency range, so as to improve the failure recognition efficiency; or outputting a plurality of audio signals corresponding to different audio sizes according to a preset audio range, so as to output different audio signals according to different use environments and optimize fault recognition quality.

As an extended embodiment of the present application, based on the above example, according to different usage environments, different audio signals corresponding to the audio size may be output according to the preset audio range by controlling the sounding module 110, specifically, before the audio signal is sent out by the sounding module 110, the external audio signal may be detected by the microphone module 120, and the audio parameter of the external audio signal may be determined, so as to obtain the environmental audio parameter. And then, executing step S100 to output an audio signal corresponding to the audio size of the preset audio range, receiving and determining, through step S200, an actual audio parameter output to the environment outside the vehicle by the sound generating module 110, comparing the actual audio parameter obtained through step S200 with the obtained environmental audio parameter, comparing the actual audio parameter obtained through step S200 with the preset audio range after eliminating the influence of environmental audio such as environmental noise, and determining that the microphone is faulty when the actual audio parameter is outside the preset audio range.

In the embodiment of the present application, the sounding module 110 is controlled to output an audio signal corresponding to the audio size according to the preset audio range; receiving the off-vehicle audio signal detected by the microphone module 120 and determining an actual audio parameter of the off-vehicle audio signal; when the actual audio parameters are out of the preset audio range, the microphone faults are determined, and under the condition that the off-vehicle microphone is not disassembled, whether the microphone faults occur or not and whether the off-vehicle microphone faults fail due to the fact that environmental sundries such as icing and earth blockage are blocked or not are judged and recognized through the received off-vehicle audio signals, so that the fault recognition efficiency and recognition effect are effectively improved, and user experience is optimized.

In the embodiment of the present application, the preset audio range may be an audio parameter obtained by the microphone module outside the vehicle and other microphone assemblies 100 in the actual use process and in the historical test data, and the preset audio range may be a parameter range, or may also be a dynamic value set according to the actual use environment, etc. Specifically, the phase, frequency and the like of the received actual audio parameters of the audio signal outside the vehicle can be compared with the phase, frequency and the like of the preset audio range, and the audio parameter judgment such as the audio volume and the like of the actual audio parameters is synthesized under the conditions of high environmental noise, open environment outside the vehicle and the like, so that the fault recognition effect is prevented from being influenced due to environmental interference and the like. The audio parameters include, but are not limited to, audio phase, audio frequency, and audio volume, and may specifically include at least one of audio phase, audio frequency, and audio volume according to actual settings, which are not limited herein.

step S400, corresponding fault alarm signals are generated according to microphone faults. The method is used for reminding a user of faults through the generated fault alarm signals.

In addition, different fault alarm signals can be generated according to different reasons which lead to the fault of the microphone. Specifically, the causes of the microphone failure include, but are not limited to, hardware failure, microphone blockage, etc., and specifically the microphone failure types may be divided according to the different causes of the microphone failure, and different failure alarm signals may be generated according to the microphone failure types.

In one embodiment, the microphone fault includes a hardware failure fault and a blocking fault, and step S400, generating a corresponding fault alarm signal according to the microphone fault includes:

when the off-board audio signal is not received, determining that a hardware failure fault exists, and generating a hardware fault alarm signal;

and determining that a blockage fault exists when the actual audio parameter is out of the preset audio range, and generating a blockage fault alarm signal.

The method is used for judging whether the microphone is failed in hardware or blocked, so that the problem that the cause of the microphone failure cannot be accurately identified to influence the maintenance and the use of the off-vehicle microphone is avoided.

Alternatively, the reason why the hardware failure fault is determined to exist when the external audio signal is not received may be that the sounding module 110 is unable to effectively output the audio signal of the corresponding audio size according to the preset audio range; alternatively, the off-vehicle audio signal may not be detected due to a malfunction of the sound pickup hole 150 or the microphone module 120; the reason why the method for identifying the microphone fault outside the vehicle is controlled and executed by the control component 200 according to the present invention may be that the control component 200 such as the controller 210 fails to receive the audio signal outside the vehicle, or that the communication module such as the audio bus module between the microphone module 120 and the control component 200 such as the controller 210 fails to effectively transmit the audio signal outside the vehicle to the control component 200 after detecting the audio signal outside the vehicle, which results in a hardware failure.

Specifically, when the out-of-vehicle audio signal is not received, determining that a hardware failure fault exists, generating a hardware fault alarm signal and the like; when the external audio signal is received, determining that no hardware failure fault exists, further comparing the actual audio parameter of the received external audio signal with a preset audio range, determining that a blockage fault exists when the actual audio parameter is out of the preset audio range, and generating a blockage fault alarm signal. Therefore, passengers and other users of the driver can be helped to identify the reasons causing the failure of the microphone fault, and the user is further reminded to take corresponding fault maintenance measures by reminding the user whether the microphone fault is caused by the microphone hardware fault or the microphone blocking fault.

Further, in the daily use process, the device can be used for controlling to start the off-vehicle microphone fault recognition device when power is on, and controlling the sounding module 110 to output an audio signal with a corresponding audio size according to a preset audio range so as to determine that a hardware failure fault exists when the off-vehicle audio signal is not received; when an off-vehicle audio signal is received, comparing an actual audio parameter of the received off-vehicle audio signal with a preset audio range, determining that a blocking fault exists when the actual audio parameter is out of the preset audio range, and determining that the blocking fault does not exist when the actual audio parameter is in the preset audio range.

In addition, during the daily operation, when the sounding module 110 or the microphone module 120 cannot work normally, the off-vehicle microphone fault recognition method may be performed by automatically controlling the on-vehicle terminal or manually inputting and controlling the off-vehicle microphone fault recognition device by the user through the input device such as the keyboard and the key; or, after detecting the failure of the microphone assembly 100 such as the microphone module 120 and the sounding module 110 in the daily microphone self-checking process and outputting a failure alarm signal to the vehicle-mounted terminal of the vehicle to prompt the user, the vehicle-mounted terminal automatically controls or the user manually inputs and controls the off-vehicle microphone failure recognition device through the input device such as a keyboard and a key to execute the off-vehicle microphone failure recognition method.
