[0031] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.
[0032] The specific embodiments of the present application are described in further detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not used to limit the scope of the present application.
[0033] The prior art relies on manual testing for the detection of the volume with speed adjustment function, which is highly subjective, the results are difficult to quantify, and the test consistency is low. The difference in listening feeling of different gain effects is small, and multiple tests are needed to distinguish, which is low in test efficiency and time-consuming and labor-intensive. There is a lack of objective data support, which is easy to draw wrong conclusions. Manual testing can only rely on qualitative description and cannot provide quantitative data of the volume gain curve, which is not conducive to problem cause analysis and optimization.
[0034] The present application directly reads the vehicle speed signal and controls the vehicle to enter the target speed through automatic script, eliminates manual operation errors, and records the mapping relationship between the vehicle speed and the volume in real time through timestamp alignment without manual intervention, and realizes the full-automatic test process.

[0036] In the above implementation process, the vehicle is automatically tested for volume with speed adjustment according to the test script, and the obtained test data is compared with the preset data to obtain the test result of the volume with speed of the vehicle-mounted audio. The automatic and sustainable volume with speed test can be realized without relying on manual detection, the test consistency is high, the efficiency is higher, and multiple accurate tests can be realized to provide more data support for the adjustment of the vehicle-mounted audio.
[0037] In S1, the vehicle information and the audio software version are identified, and the audio software version is read to obtain the preset data corresponding to the audio software version.
[0038] In the present application, the vehicle information identification mainly performs vehicle information detection, controller software version identification (such as audio software version), software information input, etc. The frame number information of the vehicle and the software version information of the audio system controller are read through the CANoe tool.
[0039] The embodiment of the application is realized by a test device (a decibel tester, a notebook computer), and the test device is arranged at a fixed position in the vehicle.
[0040] Further, S3 comprises: obtaining a CAN bus signal of the vehicle; detecting, according to the CAN bus signal, whether a seat belt, a door, a trunk and a front hood of the vehicle are in a closed state; if yes, determining that the vehicle is in a safe state; if no, determining that the vehicle is in an unsafe state, and the volume-speed test cannot be performed.
[0041] In the implementation process, the safety state of the vehicle is detected before the volume-speed test is performed, so as to avoid that noise hidden dangers in the vehicle driving process affect the test, avoid unnecessary noise, and provide environmental support for extraction of volume data.
[0042] When the tester clicks the program to start the test, it is detected through the CAN signal whether the driver has fastened the seat belt, the four doors, the trunk and the front hood are closed, to ensure the safety of the tester, and when the safety state is ensured, the test script based on the CAN bus is started.
[0043] Further, S4 comprises: controlling the vehicle audio to play audio according to an audio playing instruction; adjusting the volume of the audio according to the test script, to a preset volume; controlling the vehicle to drive according to a vehicle driving instruction, to obtain first change data of the vehicle speed changing with time from 0 to a preset vehicle speed; obtaining second change data of the volume of the vehicle audio changing with time during the process that the vehicle drives from 0 to the preset vehicle speed; obtaining test data according to the first change data and the second change data.
[0044] In the implementation process, the vehicle speed is controlled to increase from 0 to the preset vehicle speed, and the change data of the vehicle speed changing with time and the data of the volume changing with time during the process are obtained, both of which take time as a measurement standard, so that the speed test process is more accurate.
[0045] The audio playing instruction is obtained through the CANoe tool, and the volume of the audio is adjusted to a preset volume. The vehicle driving instruction is sent by an automatic program of the test script, the vehicle speed is controlled to increase from 0 to the preset vehicle speed according to the set vehicle speed ladder, and the change information of the speed with time (first change data) is recorded. The automatic program controls the decibel tester to detect the volume information in the vehicle, and the change information of the volume with time (second change data) is recorded.
[0046] Further, the step of obtaining the test data according to the first change data and the second change data comprises: obtaining third change data of the volume change with the vehicle speed according to the first change data; obtaining fourth change data of the volume change sensitivity change with the vehicle speed according to the first change data; obtaining the test data according to the third change data and the fourth change data.

[0049] In the above implementation process, the driving speed of the vehicle is positioned to a specific speed point according to the preset speed resolution, and then the volume change corresponding to each speed point is extracted, which can improve the test efficiency of the volume change with the speed, accurately correspond the volume change to the vehicle speed, and reduce the error.
[0050] According to the preset speed resolution, the volume detection information corresponding to each speed point is found out to form the third change data of the volume change with the vehicle speed.
[0051] Further, the step of obtaining the fourth change data of the volume change sensitivity change with the vehicle speed according to the first change data comprises: obtaining a preset volume change sensitivity; splitting the first change data according to the volume change sensitivity to obtain the time corresponding to each volume change sensitivity change; extracting the second volume detection data at the time corresponding to each volume change sensitivity change in the second change data; generating the fourth change data of the volume change sensitivity change with the vehicle speed according to each volume change sensitivity and the second volume detection data.
[0052] In the implementation process, the time node corresponding to each volume change sensitivity is extracted according to the preset volume change sensitivity and time binding, which can improve the extraction accuracy of the volume change sensitivity and more easily capture the degree of volume change.
[0053] The volume change sensitivity is set to low, medium and high, and the fourth change data of the volume change with the vehicle speed under different volume change sensitivities is generated, which can meet the design requirements of the volume gain intensity under different sensitivities.
[0054] Further, the step of obtaining test data according to the third change data and the fourth change data comprises: comparing the third change data and the fourth change data according to time to obtain test data; The test data includes a preset volume change curve with vehicle speed, an actual volume change curve with vehicle speed, a volume change gain curve with vehicle speed under different sensitivities, and a comparison curve of preset volume and actual volume change with vehicle speed.
[0055] In the implementation process, the third change data and the fourth change data are compared according to time, and the change trend and degree of volume change with vehicle speed can be clearly and explicitly obtained, which provides data support for subsequent volume adjustment and analysis.
[0056] According to the volume-speed change information under the condition that the volume-speed adjustment function is closed, and combining the preset gain size of low, medium and high sensitivity input by the test personnel, the preset volume-speed change curve under different sensitivities is automatically calculated and compared with the actual measured volume-speed change under low, medium and high sensitivity.
[0057] Further, before the step of obtaining test data by testing the volume-speed adjustment of the vehicle according to the test script, it further comprises: Close the volume-speed adjustment function of the vehicle.
[0058] In the implementation process, the volume-speed adjustment function of the vehicle is closed to avoid the influence of the extraction of the volume and the capture of the volume change sensitivity during the driving of the vehicle.
[0059] In this application, the test script can automatically complete the test tasks of opening and closing the volume-speed adjustment function, sensitivity switching, automatic control of vehicle speed and synchronous acquisition of the volume detection results of the decibel tester. By analyzing the vehicle speed information of CANoe and the volume information of the decibel tester, the volume-speed adjustment function is closed.
[0060] In S5, the test result synchronously stores the vehicle information and the test result, compares and analyzes the test data of the sound gain at different vehicle speeds with the preset data, and outputs the test result of the sound gain at different vehicle speeds in the form of a volume gain comparison curve and a test report, that is, the test result includes two parts of test data and a test report.
[0061] The application writes the vehicle information, the preset volume change curve with the vehicle speed, the actual volume change curve with the vehicle speed, the volume gain curve with the vehicle speed at different sensitivities, the preset volume change comparison curve with the vehicle speed, and the actual volume change comparison curve with the vehicle speed into the data storage, and outputs the test result through the display screen according to the display mode setting.
[0062] The above test data can be switched in the display screen, and finally the vehicle information and the test data are written into the test report to generate the test report.
