Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vehicle sound tuning system and an electronic device. Background Technology

[0002] Compared to traditional internal combustion engine vehicles, new energy vehicles use quieter electric motor systems as their powertrains, making the vehicles much quieter during driving. However, this quietness also results in a lack of acoustic feedback during driving, making it difficult to meet the needs of some drivers for driving pleasure and social interaction. Therefore, automotive electronic sound simulation technology has gradually emerged in recent years.

[0003] In related technologies, electronic sound wave simulation systems typically store pre-set sound wave sample materials in the onboard host of the test vehicle. By collecting real-time vehicle status signals such as gear position, vehicle speed, acceleration, motor torque, accelerator pedal opening, and brake pedal opening, a sound wave synthesis algorithm determines the current vehicle operating condition and synthesizes electronic sound waves in real time, which are then played through the onboard audio system's speakers. However, this process has the following problems: the sound wave sample materials and synthesis algorithm need to be pre-integrated into the target vehicle system, thus requiring customized development of the sound wave synthesis algorithm based on the vehicle system's software architecture platform and interfaces. For newly developed vehicle models, the integration of the electronic sound wave software can only begin after the vehicle system software development is completed, leading to an extended overall development cycle. Furthermore, the electronic sound wave software has poor versatility, typically only compatible with specific vehicle system models; if the vehicle system supplier does not open the system interface, the integration of the electronic sound wave function cannot be achieved. In addition, due to the lack of dedicated electronic sound wave debugging tools, the debugging process can only be achieved by repeatedly updating the vehicle system to adjust the sound wave effect, making real-time adjustment impossible and resulting in low debugging efficiency. During the debugging phase, it is difficult to simultaneously store and flexibly switch between multiple different sound wave styles; at the same time, a large amount of sound wave sample data needs to be stored, which places high demands on the storage space and computing power of the vehicle system, increasing development costs. After debugging is completed, the storage and computing resources required by the vehicle system will be idle, resulting in resource waste. Summary of the Invention

Detailed Implementation

[0018] Embodiments of this application are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be configured to explain this application, and should not be construed as limiting this application.

[0019] The following describes in detail, with reference to the accompanying drawings, a vehicle sound tuning system and an electronic device according to embodiments of this application.

[0020] Reference Figure 1 The vehicle sound tuning system 1 of this application embodiment includes a parameter interaction module 11, a sound editing module 12, and an evaluation module 13, wherein, The parameter interaction module 11 is configured to obtain the current vehicle status information through the vehicle communication interface and transmit the current vehicle status information to the sound wave editing module 12; The sound wave editing module 12 is configured to edit the mapping relationship between vehicle status information and vehicle sound wave parameters based on the original vehicle sound wave file, determine the target vehicle sound wave based on the current vehicle status information and the mapping relationship, and transmit the target vehicle sound wave to the vehicle speaker for playback; Evaluation module 13 is configured to collect the target vehicle sound waves played by the vehicle's loudspeakers and determine the score value of the target vehicle sound waves so as to re-edit the mapping relationship between vehicle status information and vehicle sound wave parameters based on the score value.

[0021] Specifically, one end of the parameter interaction module 11 is connected to the vehicle's CAN interface to obtain vehicle status information in real time, including vehicle speed, motor speed, torque, accelerator pedal opening, etc. The other end of the parameter interaction module 11 is connected to the sound editing module 12 and can output the vehicle status information to the sound editing module to control the sound to change in real time according to the vehicle status.

[0022] The sound wave editing module 12 stores the original vehicle sound wave file, which includes multiple vehicle sound wave sources and a corresponding source number for each source. The debugging personnel can edit the vehicle status information based on these sources, such as setting one or more source numbers to create a mapping relationship between the vehicle status information and the sound wave parameters. After receiving the vehicle status information, the sound wave editing module 12 matches the corresponding target sound wave parameters according to the mapping relationship, thereby driving the sound wave synthesis algorithm to generate a target vehicle sound wave that highly matches the vehicle's real-time operating conditions. Finally, the target vehicle sound wave is transmitted to the vehicle's speakers for playback.

[0023] After the vehicle speakers play the target vehicle's sound, the evaluation module 13 collects the target vehicle's sound and scores it. For example, the evaluation module 13 can integrate a quantitative model that combines objective data with subjective perception. This model analyzes the acoustic indicators of the sound (such as loudness dynamics and spectral structure), assesses its similarity to vehicle sound samples, and examines the response accuracy and linearity of the sound dynamics and real-time vehicle operating conditions (such as pedal opening and motor torque). Through weighted calculation, it obtains the score value of the target vehicle's sound, thereby achieving an accurate and efficient evaluation of the sound quality.

[0024] After determining the target vehicle's sound score, this score is compared to a preset sound score threshold to determine if the mapping between vehicle status information and sound parameters needs to be re-edited. For example, if the target vehicle's sound score is greater than or equal to the preset threshold, the sound effect is good, and therefore no re-editing of the mapping between vehicle status information and sound parameters is required. Conversely, if the target vehicle's sound score is less than the preset threshold, the sound effect is poor, and therefore no re-editing of the mapping between vehicle status information and sound parameters is required. The preset sound score threshold can be set according to actual conditions; for example, a preset threshold of 95 points is not specifically limited here.

[0025] The debugging system described in this application effectively solves the problems of long development cycles, strong system dependence, low debugging efficiency, and insufficient resource utilization in traditional electronic sound wave simulation technology through the coordinated operation of parameter interaction modules, sound wave editing modules, and evaluation modules. Specifically, the system achieves real-time acquisition of vehicle status information and flexible editing of sound wave parameters through an external design, eliminating strong dependence on specific vehicle systems and preset samples, and significantly improving the versatility and integration efficiency of sound wave simulation functions. At the same time, the introduction of an evaluation module based on a multi-dimensional quantitative model can accurately evaluate the acoustic quality and operating condition matching degree of the generated sound waves, and provide real-time feedback to the editing stage based on the scoring results, forming a closed-loop debugging process of "acquisition-editing-playback-evaluation-optimization". This not only significantly reduces the resource consumption of vehicle system storage and computing power during debugging, and enables rapid switching and iterative optimization of multiple sound wave styles, but also shortens the overall development cycle and reduces development costs, thereby improving system adaptability and resource utilization efficiency while ensuring the sound wave simulation effect.

[0026] In some embodiments, refer to Figure 2 The sound wave editing module 12 includes a sound source setting unit 121, a sound wave editing unit 122, and a sound wave generation unit 123, wherein... The sound source setting unit 121 is configured to receive the actual vehicle sound source file and / or the preset waveform sound source file, and generate the original vehicle sound file based on the actual vehicle sound source file and / or the preset waveform sound source file. The sound wave editing unit 122 is configured to respond to an editing command and edit the vehicle sound wave parameters corresponding to the vehicle status information based on the original vehicle sound wave file, so as to generate a mapping relationship between the vehicle status information and the vehicle sound wave parameters. The sound wave generation unit 123 is configured to receive the current vehicle status information, determine the vehicle sound wave target parameters based on the current vehicle status information and mapping relationship, determine the target vehicle sound wave based on the vehicle sound wave target parameters, and transmit the target vehicle sound wave to the vehicle speaker for playback.

[0027] In some embodiments, the sound source setting unit 121 is configured to: cut a vehicle actual sound source file to generate multiple vehicle actual sound source slices; generate an original vehicle sound file based on the multiple vehicle actual sound source slices, wherein the original vehicle sound file includes multiple vehicle actual sound source slices and a slice number for each vehicle actual sound source slice; and / or, synthesize sound based on multiple preset waveform sound source files to generate multiple synthesized vehicle sound sources; generate an original vehicle sound file based on the multiple synthesized vehicle sound sources, wherein the original vehicle sound file includes multiple synthesized vehicle sound sources and a sound source number for each synthesized vehicle sound source.

[0028] In some embodiments, the vehicle sound parameters include the slice number if the original vehicle sound file includes multiple actual vehicle sound source slices and a slice number for each actual vehicle sound source slice; and / or, if the original vehicle sound file includes multiple synthesized vehicle sound sources and a source number for each synthesized vehicle sound source, the vehicle sound parameters include the source number.

[0029] Specifically, the sound source setting unit 121 integrates a communication interface, which receives the actual vehicle sound source file, the preset waveform sound source file, or both the actual vehicle sound source file and the preset waveform sound source file through the communication interface. The actual vehicle sound source file refers to the sound audio file recorded from a real vehicle, while the preset waveform sound source file refers to a waveform signal with a specific frequency and waveform, such as a sine wave, triangle wave, or square wave.

[0030] After receiving the actual vehicle sound source file and / or the preset waveform sound source file, the sound source setting unit 121 generates the original vehicle sound file based on the actual vehicle sound source file and / or the preset waveform sound source file. For example, upon receiving an actual vehicle sound source file, the file is cut to create multiple actual vehicle sound source slices. These slices are then numbered to form multiple actual vehicle sound source slice-slice numbers, and stored in a preset location to form the original vehicle sound file. Alternatively, upon receiving a preset waveform sound source file, the preset waveform sound sources within the file are randomly synthesized. For example, a sine wave is synthesized with a triangle wave, a sine wave with a rectangular wave, or a sine wave, a triangle wave, and a rectangular wave to generate multiple synthesized vehicle sound sources. These synthesized vehicle sound sources are then numbered to form multiple synthesized vehicle sound source-slice numbers, and stored in a preset location to form the original vehicle sound file. Furthermore, upon receiving both a preset waveform sound source file and an actual vehicle sound source file, the original vehicle sound file includes both multiple synthesized vehicle sound source-slice numbers and multiple actual vehicle sound source slice-slice numbers.

[0031] Furthermore, the sound wave editing unit 122 can receive editing instructions from the debugging personnel and bind the vehicle status information with the vehicle sound wave parameters in the original vehicle sound wave file based on the editing instructions. Specifically, when the original vehicle sound wave file includes multiple actual vehicle sound wave source slices and a slice number for each actual vehicle sound wave source slice, the vehicle sound wave parameters include the slice number; when the original vehicle sound wave file includes multiple synthesized vehicle sound wave sources and a source number for each synthesized vehicle sound wave source, the vehicle sound wave parameters include the source number; when the original vehicle sound wave file includes multiple actual vehicle sound wave source slices and a slice number for each actual vehicle sound wave source slice, as well as multiple synthesized vehicle sound wave sources and a source number for each synthesized vehicle sound wave source, the vehicle sound wave parameters include both the actual vehicle sound wave source slices and the slice number, and multiple synthesized vehicle sound wave sources and a source number for each synthesized vehicle sound wave source, the vehicle sound wave parameters include both the actual vehicle sound wave source slices and the slice number, and multiple synthesized vehicle sound wave sources and their respective source numbers. In other words, the sound wave editing unit 122 can bind the vehicle status information with the source number and / or slice number in the original vehicle sound wave file based on the editing instructions to generate a mapping relationship between the vehicle status information and the vehicle sound wave parameters. For example, when the vehicle status information includes the current engine speed of 2800 RPM, the current throttle opening of 55%, the current gear of 3, and the driving mode of Sport, the bound vehicle sound parameters are slice number 1, slice number 2, and slice number 3; when the vehicle status information includes the current engine speed of 2900 RPM, the current throttle opening of 60%, the current gear of 3, and the driving mode of Sport, the bound vehicle sound parameters are slice number 2, slice number 3, and slice number 4.

[0032] During the debugging process, the sound wave generation unit 123 can receive the current vehicle status information in real time. For example, if the received vehicle status information includes the current engine speed of 2900 RPM, the current throttle opening of 60%, the current gear of 3, and the driving mode of Sport, then the target parameters for the vehicle sound wave are determined to be slice number 2, slice number 3, and slice number 4. Then, based on the target parameters, the target vehicle sound wave is determined. For example, the actual vehicle sound wave source slices corresponding to slice number 2, slice number 3, and slice number 4 are connected to generate the target vehicle sound wave, and the target vehicle sound wave is transmitted to the vehicle speakers for playback.

[0033] This application uses a sound source setting unit to slice or synthesize real-vehicle recorded sound sources or preset waveform sound sources, generating original vehicle sound files containing numbered sound source data. A sound source editing unit then precisely binds vehicle status information with sound parameters (slice number or sound source number) according to debugging instructions, establishing a flexibly configurable mapping relationship. Based on this, the sound source generation unit can respond in real-time to changes in vehicle status, quickly matching and calling the sound source slice or synthesized sound source corresponding to the target sound parameters, dynamically generating a target sound that highly matches the vehicle's operating state. This effectively achieves precise control and efficient generation of vehicle sound, significantly improving the realism and real-time responsiveness of sound simulation, while enhancing debugging flexibility and system adaptability, meeting diverse sound customization needs.

[0034] In some embodiments, continue to refer to Figure 2 The sound wave editing module 12 also includes a sound wave adjustment unit 124, wherein the sound wave adjustment unit 124 is configured to adjust the sound wave of the target vehicle based on a preset adjustment method, the preset adjustment method including one or more of amplitude adjustment, frequency shift adjustment, equalizer adjustment, random fluctuation adjustment, high-pass filtering, low-pass filtering and band-pass filtering.

[0035] Specifically, refer to Figure 3 After receiving the target vehicle's sound wave, the sound wave adjustment unit 124 allows the technician to adjust the sound wave according to preset methods, such as amplitude adjustment, frequency shift adjustment, equalizer adjustment, random fluctuation adjustment, high-pass filtering, low-pass filtering, and band-pass filtering. It can also be set to adjust the amplitude and frequency of the target vehicle's sound wave in real time according to vehicle status information, for example, by referring to... Figure 4 The higher the vehicle speed, the higher the amplitude and frequency of the target vehicle's engine sound; similarly, the higher the rate of change of the accelerator pedal, the higher the amplitude and frequency of the target vehicle's engine sound; furthermore, referring to... Figure 5 The greater the motor torque, the higher the amplitude and frequency of the target vehicle's sound wave.

[0036] In this way, technicians can flexibly utilize various adjustment methods such as amplitude, frequency shift, equalizer, and filtering to precisely shape the intensity, pitch, spectral distribution, and dynamic characteristics of the sound waves according to actual needs. Furthermore, by establishing a real-time linkage mechanism between sound wave parameters and vehicle status (such as vehicle speed and throttle change rate), the generated target sound waves are not only fundamentally accurate but also dynamically and non-linearly respond to driving intentions and changes in vehicle operating conditions. This significantly enhances the immersiveness, expressiveness, and dynamic realism of the sound simulation, ultimately achieving a deep fit and vivid expression of vehicle dynamic behavior in the auditory dimension.

[0037] In some embodiments, continue to refer to Figure 2 The sound wave editing module 12 also includes a sound wave output unit 125, wherein the sound wave output unit 125 is configured to set the number of vehicle sound wave output channels according to the number of vehicle speaker channels, and output the target vehicle sound wave based on the number of vehicle sound wave output channels.

[0038] Specifically, the sound output unit 125 sets the number of vehicle sound output channels according to the number of vehicle speaker channels. For example, if the number of vehicle speaker channels is 4, then 4 vehicle sound output channels are set to output the target vehicle sound.

[0039] Thus, by dynamically matching the speaker channels and the sound wave output channels, the complete transmission and hardware compatibility of audio signals in the complex in-vehicle audio system are ensured. Secondly, by utilizing multi-channel independent control technology, spatial positioning of sound sources based on the vehicle's physical structure is achieved, which can accurately simulate the directional characteristics of different sound sources such as the engine compartment and exhaust system. Finally, through differentiated sound effect processing and collaborative output of each channel, an in-vehicle sound field with a three-dimensional feel is constructed, which significantly improves the spatial realism of the sound wave simulation and the driving immersion, making the synthesized sound waves and the vehicle's dynamic behavior form a highly unified auditory feedback.

[0040] In some embodiments, continue to refer to Figure 2 The debugging system 1 also includes an audio output module 14, wherein the audio output module 14 is configured to receive the target vehicle sound wave and the vehicle speaker sound parameters, and adjust the vehicle speaker based on the speaker sound parameters to control the vehicle speaker to play the target vehicle sound wave, wherein the vehicle speaker sound parameters include one or more of the vehicle speaker's sound frequency range, sound gain, and sound delay.

[0041] Specifically, the audio output module 14 can be connected to the sound output unit 125 of the sound wave editing module 12 to receive the sound wave of the target vehicle and transmit it to the vehicle speaker; it can also receive vehicle speaker sound parameters from the debugging personnel, such as one or more of the vehicle speaker's frequency range, sound gain, and sound delay, to adjust the vehicle speaker, and the frequency response curves before and after adjustment are as follows: Figure 6 As shown.

[0042] In this way, by loading specific frequency ranges, gain curves and delay parameters of the loudspeaker, the target sound wave can be accurately adapted to the terminal, effectively overcoming the problems of frequency response distortion and uneven sound pressure caused by differences in loudspeaker hardware.

[0043] In some embodiments, the evaluation module 13 includes a display unit (not shown), wherein the display unit is configured to display a score value for the sound of the target vehicle.

[0044] In some embodiments, the debugging system 1 further includes a power supply module (not shown), wherein the power supply module is configured to power the sound wave editing module 12, the parameter interaction module 11, the audio output module 14, and the evaluation module 13.

[0045] As a concrete example, refer to Figure 7 The method for adjusting the engine sound of a vehicle includes the following steps: S201, Input / Output Interface Configuration.

[0046] S202, Audio Source Settings.

[0047] S203, Soundwave Editor.

[0049] S205, determine whether the evaluation is passed. If yes, proceed to S207; otherwise, proceed to S206.

[0050] S206, sound wave adjustment.

[0051] S207, finalize the solution.

[0052] In summary, the vehicle sound engine debugging system of this application is completely independent of the vehicle's in-vehicle infotainment system, is not affected by the software development progress of the in-vehicle infotainment system, does not occupy the storage space and computing power of the in-vehicle infotainment system, has universality, and can be used for electronic sound engine debugging and verification of any brand of vehicle. It can simultaneously store and switch multiple different styles of electronic sound engines, thus greatly improving work efficiency, shortening the debugging cycle, and reducing development costs.
