Detailed Description
In addition, the embodiments of the present invention and the features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
As shown in fig. 1, a vehicle sound testing method according to an embodiment of the present invention includes:
and S11, acquiring a test request instruction.
Regarding the execution subject of the embodiment of the present invention, it may be any processor or controller configured for a vehicle, and exemplarily, the processor or controller may be a processor or controller originally configured on the vehicle, such as a vehicle Control unit vcu (vehicle Control unit), an electronic Control unit ecu (electronic Control unit), a micro-controller unit MCU (micro-controller unit), and the like; in addition, the processor or controller may also be an additional processor or controller attached to the vehicle, such as a DSP (Digital Signal processing) chip; in addition, the processor or controller may be any combination of the above. Therefore, the method of the embodiment of the invention is implemented by corresponding modification on hardware and/or software, so as to realize the self-detection process of the vehicle sound, and the above embodiments are all within the protection scope of the invention.
Regarding the obtaining manner of the test request instruction, it may be that an operator generates the test request instruction through an operation terminal (the terminal may be an in-vehicle terminal or another terminal in communication with the vehicle), and transmits the test request instruction to a controller or a processor, so as to implement a vehicle audio self-detection process based on manual response; in addition, the method can also be used for realizing the full-automatic detection process of the production line corresponding to the instruction automatically generated when the production line enters the sound test stage or the whole vehicle is assembled off-line, and the above embodiments all belong to the protection scope of the invention.
And S12, controlling the loudspeaker of the vehicle to play the pre-stored test audio based on the test request instruction.
Specifically, the test audio may be pre-stored in a memory associated with the controller or processor, which may be pre-configured by the tester and stored in the memory. For the type of test audio, it may be a multiplicity of tone source settings for the test.
And S13, controlling to collect the audio signal corresponding to the played test audio.
Where the speaker is playing test audio, the test audio may be a signal corresponding to a wide audio range, for example, it may be a pink noise signal emitting audio of 20Hz to 20 kHz. Illustratively, a specific audio signal, such as a pink noise signal, is emitted by the multimedia host according to the test audio, and is emitted through a corresponding speaker after being amplified by a power amplifier and the like.
And S14, testing the loudspeaker of the vehicle according to the collected audio signal.
Specifically, on one hand, the speakers of the vehicle may be tested according to the presence or absence (or validity) of the acquired audio signal, for example, when a valid audio signal is not acquired, it may be preliminarily determined that the speaker of the currently tested vehicle or the associated power amplifier, etc. has a fault and cannot output the audio signal; on the other hand, it may be preferable to test the audio performance of the vehicle's speakers from the captured audio signals.
In the prior art, the manual vehicle sound test can only test whether the loudspeaker of the whole vehicle normally outputs or not, and can not detect whether the performance of the loudspeaker is normal or not, particularly whether the sound effect of the whole vehicle is normal or not; even if the sound effect detection is performed by a human, the quality and consistency of the sound quality can be evaluated only subjectively, and if the accuracy of the sound effect detection is ensured, special equipment needs to be installed for detection, and the test period is further prolonged.
In view of this, when testing the speakers of the vehicle according to the acquired audio signals, it is also possible to test the audio performance of the speakers according to the acquired audio signals and a desired audio signal interval pre-configured for the test audio; the expected audio signal interval may be preset by an operator or a test expert according to experience for expected performance of the test audio in the vehicle, and indicates normal signal feedback performance of the test audio in a general state. Specifically, one aspect of the method may be to directly compare the acquired audio signal or signals with a desired audio signal interval, thereby determining whether the audio signal is within the interval; on the other hand, it is also preferable that, as shown in fig. 2, the collected audio signals are sorted to generate a corresponding frequency response curve, and the frequency response curve is compared with the expected audio signal interval, so as to implement the test of the audio performance of the speaker. The test flow shown in fig. 2 includes: s21, generating a frequency response curve aiming at the test audio according to the collected audio signals; s22, judging whether the frequency response curve is in the frequency response area range indicated by the expected audio signal interval; s231, if the frequency response curve is in the range of the frequency response area, the test result for the tested loudspeaker is passed; and S232, if the frequency response curve is not in the range of the frequency response area, the test result of the tested loudspeaker is not passed.
Further, the test result of the tested speaker may be displayed after the test result for the tested speaker is generated, for example, the test result of the speaker may be displayed as PASS (PASS) or fail (NG) on the user interface; and/or generating a vehicle sound test report according to the test result of the tested loudspeaker, so that an operator can intuitively see which loudspeakers have defects and need to be debugged and maintained by browsing the test report.
As shown in fig. 3, in a vehicle to which the vehicle sound testing method according to an embodiment of the present invention is applied, 10 speakers with speaker numbers of 1-10 are provided in the vehicle, and after the whole vehicle is assembled and is off-line, it is currently necessary for a workshop operator to listen and confirm each speaker to determine whether there is an audio signal output. Specifically, a plurality of speakers are respectively provided at different positions of the vehicle and include a plurality of kinds of speakers, wherein the speaker 1 is a center speaker disposed below the front windshield at the midpoint of the instrument desk; the loudspeakers 2, 3, 6 and 7 are high pitch loudspeakers, the high pitch loudspeakers 2 and 3 are arranged at the lower position in the middle of the A column, and the high pitch loudspeakers 6 and 7 are arranged at the upper position of a metal plate of a back door; the loudspeakers 4, 5, 8 and 9 are woofers and are arranged at the positions, which are lower than the metal plates of the doors of the four doors; the speaker 10 is a subwoofer, and is disposed at the inside of the spare tire of the trunk. In addition, a microphone 12 for picking up an audio signal is arranged at the front passenger roof position; and, a processor or controller (corresponding to the sound effect processing module 11 in fig. 3) for performing the vehicle sound testing method of the embodiment method of the present invention may be disposed at the right quarter.
In the prior art, when the sound of the vehicle is manually detected, all the speakers of the whole vehicle output, so that the listening detection of an operator is interfered, and the speakers with poor functions are not easy to detect.
In view of this, the embodiment of the present invention further provides that the non-simultaneous sounding may be based on controlling multiple speakers to sound, and specifically, the vehicle speakers may be controlled to play the pre-stored test audio in response to the test request instruction in the following manner: firstly, sequentially selecting target speakers from a plurality of speakers respectively based on a test request instruction; then, the target speaker is controlled to play the test audio.
Illustratively, as shown in fig. 3, it may be that the speaker numbers are sequentially selected from 1 to 10 one by one, and the selected target speaker is controlled to play the test audio alone, thereby implementing the non-simultaneous sounding of the speakers and the testing of the sound quality performance of each speaker unit. Referring to fig. 4, which shows that different digital signals respectively correspond to different speakers, speakers with corresponding digital signal values of 1-10 are executed in the process of testing the speakers by the sound effect processing module, so as to realize sound effect testing of each speaker in sequence.
In the prior art, an operator cannot detect the audio performance of the whole vehicle by using a scheme of completely detecting whether the performance of a loudspeaker is normal, particularly whether the sound effect of the whole vehicle is normal or not. In view of this, the method of the embodiment of the present invention further provides configuring different desired audio signal intervals for the test audio for each of the plurality of types of speakers, as shown by the ranges of the dashed areas in fig. 6A to 6E.
In some embodiments, the multimedia host sends a specific audio signal, such as a pink noise signal, the specific audio signal is sent by the corresponding speaker through processing such as power amplification and amplification, the microphone installed in the reading lamp collects the audio signal sent by the speaker, and sends the collected signal to the sound effect processing module for data analysis, so as to obtain a frequency response curve of the speaker under the environmental condition. As shown in fig. 6A, when a certain speaker produces sound, the sound effect processing module processes and analyzes a signal according to the signal collected by the microphone, and the collected audio curve is smaller than the dotted line in the figure, which indicates that the microphone does not collect the sweep frequency signal sent by the speaker, and the test fails, and the test report shows that the test fails. When the test fails, the operator needs to check whether the speaker is correctly connected, whether the speaker body is qualified, whether the functional signals of the power amplifier and the host are normal, and the like.
Further, it may be possible to adopt personalized test schemes for different kinds of speakers, specifically, as shown in fig. 5: s51, determining a corresponding target expected audio signal interval according to the type of the tested target loudspeaker; and S52, testing the audio performance of the target loudspeaker according to the interval between the collected audio signal and the target expected audio signal.
In some embodiments, when the center speaker generates sound, if the sound effect processing module processes the analyzed signal frequency response curve according to the signal collected by the microphone, and the signal frequency response curve is the working condition as shown in fig. 6B, it indicates that the frequency response curve corresponding to the collected audio signal is within the range of the dashed line shown in the figure, and at this time, it proves that the center speaker is functioning normally, and accordingly PASS may be displayed for this test in the test report. In addition, correspondingly, if the frequency response curve exceeds the dashed line limit in the graph, the test fails, and the test report shows that the test NG (failed); after the test is finished, the operator needs to check whether the body of the middle speaker is qualified, whether the functional signals of the power amplifier and the host are normal, and the like.
In some embodiments, when the tweeter is sounding, if the sound processing module processes the analyzed signal frequency response curve according to the signal collected by the microphone, which indicates that the frequency response curve corresponding to the collected audio signal is within the range of the dotted line shown in fig. 6C, this test in the test report shows PASS. Correspondingly, if the frequency response curve exceeds the broken line limit in the graph, the test is failed, and the test report shows that the test is NG; after the test is finished, the operator needs to check whether the speaker body is qualified, whether the functional signals of the power amplifier and the host are normal, and the like.
In some embodiments, when the woofer sounds, if the audio processing module processes the analyzed signal frequency response curve according to the signal collected by the microphone, as shown in fig. 6D, which indicates that the frequency response curve corresponding to the collected audio signal is within the range of the dotted line, this test in the test report shows PASS. Correspondingly, if the frequency response curve exceeds the broken line limit in the graph, the test is failed, and the test report shows that the test is NG; after the test, whether operating personnel need to inspect the speaker body qualified, whether woofer resonates with the door panel beating, whether the functional signal of power amplifier and host computer is normal etc..
In some embodiments, when the subwoofer is sounding, if the sound processing module processes and analyzes the signal frequency response curve as shown in the lower graph according to the signal collected by the microphone and the frequency response curve is within the range of the dotted line area as shown in fig. 6E, it is verified that the speaker is functioning normally, and this test in the test report shows PASS. Correspondingly, if the frequency response curve exceeds the broken line limit in the graph, the test is failed, and the test report shows that the test is NG; then after the test, operating personnel need to inspect whether the speaker body is qualified, whether the subwoofer resonates with the door panel beating, whether the functional signal of power amplifier and host computer is normal, etc.
By combining the embodiments shown in fig. 6B-6E, testing of the timbre effect of various different types of speakers is achieved. Further, the embodiment of the present invention further discloses a process for testing the performance of the sound effect of the whole car after the testing of each single speaker is completed, specifically including: controlling a plurality of speakers to play the test audio simultaneously; controlling and collecting the audio signals of the whole vehicle corresponding to the simultaneous playing of the plurality of loudspeakers; and testing the whole vehicle audio performance of the vehicle according to the collected whole vehicle audio signal.
Therefore, after the speakers respectively play the sweep frequency signals, detection is carried out on all the speakers of the whole vehicle; at the moment, all loudspeakers of the whole vehicle play pink noise signals from 20Hz to 20kHz, the related steps are repeated, the microphone at the reading lamp continues to acquire audio signals in the vehicle, and the sound effect processing module analyzes and processes the signals acquired by the microphone to obtain a frequency response curve of the sound effect of the whole vehicle.
When the sound effect processing module processes and analyzes a signal frequency response curve according to the signal acquired by the microphone, and the signal frequency response curve is a working condition as shown in fig. 7, the sound effect processing module proves that the performance of the loudspeaker of the whole vehicle is normal when the frequency response curve is in a dotted line range area, and the PASS is displayed in the test report; correspondingly, if the frequency response curve exceeds the broken line limit in the graph, the test is failed, and the test report shows that the test is NG; after the test is finished, the operator needs to inform the developer to check and confirm the existing problems.
Specifically, an operator clicks the automatic detection space to trigger the MCU to call a test audio or sound source from the F L ASH memory, transfer the test audio or sound source to the DSP chip, and control the output from the speaker (speech) via the power amplifier IC circuit, after that, the DSP chip collects an audio signal through the microphone MIC to perform signal analysis on the collected audio signal, determines that the test result is passed when a valid audio signal is collected or the collected audio signal is within an expected range, and displays the test result as PASS on the user interface UI, and correspondingly, determines that the test result is failed when a valid audio signal is not collected or the collected audio signal is not within an expected range, and displays the test result as NG on the user interface UI.
In the embodiment of the invention, a full-automatic detection scheme is provided after the whole vehicle is assembled and offline, and whether the loudspeaker works or not, the performance of the loudspeaker and the sound effect of the whole vehicle are detected, so that manpower and material resources are saved, the detection accuracy is improved, detection equipment does not need to be additionally arranged, and the beat and the efficiency of the whole vehicle production are accelerated.
