[0022] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0023] The following describes in detail the vehicle interactive sound testing equipment, system and vehicle according to the embodiments of the present application with reference to the accompanying drawings.

[0024] In some embodiments, reference Figure 1 The vehicle interactive sound test device 1 includes: an information acquisition module 11, which is used to collect the vehicle's operating status information when a prompt sound command is received; a control module 12, which is used to number the vehicle's operating status information to determine the number information corresponding to the operating status information; a signal processing module 13, which is used to determine the corresponding sound source file according to the corresponding relationship between the sound source file and the number information, and output the interactive sound based on the sound source file to drive the vehicle speaker 3.

[0025] Specifically, when the tester triggers the prompt sound action, such as turning on the left turn signal, right turn signal, double flash, reversing and shifting, the corresponding prompt sound command will be sent to the information collection module 11. When the information collection module 11 receives the prompt sound command, it will collect the corresponding vehicle operation status information through the CAN (Controller Area Network) interface 2, such as collecting interactive sound signals such as left turn, right turn, double flash, reversing radar 1 to 4 levels, gear position, various prompt alarm sound signals, and simulated sound signals (vehicle speed signal, engine / motor speed signal, torque signal, acceleration signal), and transmit the collected vehicle operation status information to the control module 12. Among them, the CAN interface 2 is connected to the information collection module 11 in communication, such as wired connection or wireless connection, so that the vehicle interactive sound test equipment 1 is completely independent of the vehicle.

[0026] After receiving the running status information of the vehicle, the control module 12, such as MCU (Microcontroller Unit), performs number processing on the running status information of the vehicle to determine the number information corresponding to the running status information. For example, left and right turns correspond to number 1, unfastened seat belts correspond to number 2, D gear corresponds to number 3, R gear corresponds to number 4, and the first level of reversing radar corresponds to number 5. After determining the number information, a corresponding relationship between the number information and the corresponding sound source file can be established, as shown in Table 1.

[0029]

[0030] After the control module 12 determines the number information corresponding to the running status information, it transmits the number information to the signal processing module 13, such as a DSP (Digital Signal Processor). After receiving the number information, the signal processing module 13 calls the audio source file corresponding to the number information for decoding, and outputs the analog electrical signal corresponding to the audio source file to the vehicle speaker 3, so as to drive the vehicle speaker 3 to emit the interactive sound corresponding to the vehicle status information, so as to provide subjective and objective evaluation for the test and evaluation personnel. Among them, the vehicle speaker 3 is connected to the signal processing module 13 in communication, such as a wired connection or a wireless connection, so that the vehicle interactive sound test device 1 is completely independent of the vehicle.

[0031] The vehicle interactive sound test equipment of the present application is completely independent of the host and instrument development, and can independently complete the development and testing of the interactive sound to meet the review node requirements and quality requirements of the interactive sound.

[0032] In some embodiments, reference Figure 2 The test device 1 further includes a storage module 14, which is connected to the signal processing module 13 and is used to store the corresponding relationship of the audio source files. The storage module 14 can be a flash.

[0033] In some embodiments, continue to refer to Figure 2 The test device 1 also includes: a virtual channel conversion module 15, which is used to transmit the vehicle media sound to the signal processing module 13; the signal processing module 13 is also used to mix the vehicle media sound and the interactive sound to drive the speaker 3 based on the mixed interactive sound.

[0034] Specifically, the vehicle media audio module 4 is connected to the virtual channel conversion module 15 in communication, such as by wired connection or wireless connection, so that the vehicle interactive audio test device 1 is completely independent of the vehicle. The vehicle media audio module 4 transmits the vehicle media audio, such as navigation audio, video audio or music audio, to the virtual channel conversion module 15, and the virtual channel conversion module 15 transmits the media audio to the signal processing module 13, and the signal processing module 13 mixes the media audio and the interactive audio, and drives the vehicle player 3 to play at the same time, for example, when playing music, the interactive audio prompt effect is evaluated under different music volume levels.

[0035] In this way, it is possible to evaluate the sound status of the interactive sound when playing the media sound.

[0036] In some embodiments, continue to refer to Figure 2 The control module 12 includes: a first communication unit 121, which is used to communicate with the host computer 5.

[0037] In some embodiments, continue to refer to Figure 2 The signal processing module 13 includes: a second communication unit 131, which is used to communicate with the host computer 5.

[0038] Specifically, the host computer 5 is connected to the control module 12 through the first communication unit 121, and is connected to the signal processing module 13 through the second communication unit 131, such as wireless connection or wired connection, so that the vehicle interactive sound test device 1 is completely independent of the vehicle. The tester can edit the control module 12 and the signal processing module 13 through the software on the host computer 5.

[0039] Corresponding to the above-mentioned embodiment, the present application also proposes a vehicle interactive sound testing system.

[0040] Reference Figure 3The vehicle interactive sound test system 10 includes the aforementioned vehicle interactive sound test device 1 and a host computer 5, wherein the host computer 5 is communicatively connected with the vehicle interactive sound test device 1 via a first communication unit 121 and a second communication unit 131, wherein the host computer 5 is configured to edit the signal processing module 13 upon receiving a first editing instruction to update the corresponding relationship of the sound source file.

[0041] Specifically, the tester can issue a first editing instruction. When the upper computer 5 receives the first editing instruction, it edits the signal processing module 13 to update the correspondence between the sound source files, for example, replacing the sound source files corresponding to the encoding, adding the correspondence between the encoding and the sound source files, editing the sound source files corresponding to the encoding, etc.

[0042] In some embodiments, continue to refer to Figure 3 The host computer 5 is also used to edit the control module 12 to update the CAN file to adapt to different vehicle models when receiving the second editing instruction.

[0043] Specifically, the tester can issue a second editing instruction, and when the host computer 5 receives the second editing instruction, it edits the control module 12 and changes the CAN file to achieve commonality among different vehicle models.

[0044] In some embodiments, continue to refer to Figure 3 The host computer 5 is also used to edit the signal processing module 13 to adjust the output parameters of the signal processing module 13 when receiving the third editing instruction; wherein the output parameters of the signal processing module 13 include one or more of the volume and timbre of the interactive sound.

[0045] Specifically, the tester can also issue a third editing instruction. When the upper computer 5 receives the third editing instruction, it edits the signal processing module 13 to adjust the output parameters of the signal processing module 13, such as adjusting the volume of the interactive sound by adjusting the output gain of the signal processing module 13, and adjusting the timbre of the volume of the interactive sound by changing the filter of the signal processing module 13.

[0046] In addition, you can also use the EQ (Equalizer) of interactive audio to adjust the amplitude of different frequency components in the audio signal to improve the sound quality, enhance or reduce specific frequency bands, and perform fine frequency domain processing on the interactive audio signal. You can also edit the audio files of interactive audio, such as copying, cutting and replacing.

[0047] In this way, the evaluation of various types of interactive sound timbre, sound pressure level, etc. can be quickly achieved.

[0048] In some embodiments, the host computer 5 is used to update the corresponding relationship of the sound source file, specifically including: replacing the sound source file corresponding to the code, adding the corresponding relationship between the code and the sound source file, editing the sound source file corresponding to the code. Among them, editing the sound source file corresponding to the code refers to operations such as copying, cutting and replacing the sound source file.

[0049] In this way, comparative evaluation of different sound sources of the same interactive sound can be achieved.

[0050] In summary, the vehicle interactive sound test equipment of the present application is completely independent of the development of the host and instrument, and can independently complete the development and testing of the interactive sound, meet the review node requirements and quality requirements of the interactive sound, and can perform CAN signal analysis and encoding for different models, and associate the corresponding interactive sound, which is universal for all vehicles; the signal processing module can also be edited in real time, and by updating the corresponding relationship of the sound source file, the comparative evaluation of different sound sources of the same interactive sound can be realized, and by adjusting the volume and timbre in real time, performing EQ, cutting, copying and replacing and other operations, the timbre, sound pressure level and other evaluations of various types of interactive sounds can be quickly realized; the media sound and interactive sound can also be mixed, and the vehicle-mounted speakers can be driven to play at the same time, so as to realize the evaluation of the interactive sound state when playing the media sound. In this way, the interactive sound tuning and review can be completed quickly, saving the development and testing cycle, and ensuring the development and testing quality of the vehicle interactive sound.
