Description

Technical Field

[0001] This application relates to the field of vehicle technology, specifically to a method, apparatus, vehicle, and storage medium for simulating sound waves. Background Technology

[0002] With increasing global awareness of environmental protection, new energy vehicles are gaining more and more attention in the market. New energy vehicles are characterized by their environmental friendliness, energy efficiency, and affordability, offering a more comfortable driving experience and faster acceleration response. Therefore, more and more users are choosing new energy vehicles as their mode of transportation.

[0003] While the advantages of new energy vehicles are obvious, some users, lacking the engine of traditional gasoline vehicles, cannot experience the engine sound of a traditional gasoline car and are thus forced to choose gasoline vehicles as their mode of transportation. Although most current new energy vehicles are equipped with simulated engine sounds, the simulated sounds are too monotonous and lack depth, failing to gain user acceptance. Therefore, how to improve the depth and complexity of simulated engine sounds, thereby enhancing the user's driving experience, is an urgent problem to be solved. Summary of the Invention

[0004] This application provides a method, apparatus, vehicle, and storage medium for simulating engine sound, which enhances the sense of depth in the simulated engine sound and thus improves the user's driving experience.

[0005] The technical solution provided by this application is as follows: According to the first aspect provided by this application, a method for simulating sound waves is provided. The method includes: after activating the sound wave simulation function, obtaining the current speed of the vehicle; after detecting that the current speed of the vehicle is within a first speed range, playing a first audio; after detecting that the current speed of the vehicle reaches the lower limit of a second speed range, playing a second audio, and adjusting the volume of the first audio according to the current speed of the vehicle until the first audio stops playing, wherein the lower limit of the second speed range is greater than or equal to the upper limit of the first speed range.

[0006] According to the above technical means, when the vehicle's current speed is within the first speed range, the first audio corresponding to the first speed range is played to achieve the effect of simulating sound waves. When the vehicle's current speed reaches the lower limit of the second speed range, the second audio is played, and the volume of the first audio corresponding to the first speed range is adjusted according to the vehicle's current speed. This achieves the superposition of the two audio segments, thereby improving the sense of layering of the simulated sound waves and thus improving the user's driving experience.

[0007] In one possible implementation, when the vehicle's current speed is within a first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed; when the vehicle's current speed is within a second speed range, the volume of the first audio signal is negatively correlated with the vehicle's current speed, and the volume of the second audio signal is positively correlated with the vehicle's current speed.

[0008] Based on the aforementioned technical methods, when the vehicle's current speed falls within the first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed, allowing the audio volume to be adjusted according to vehicle speed, providing users with a more realistic driving experience. When the vehicle's current speed falls within the second speed range, the volume of the first audio signal is negatively correlated with the vehicle's current speed, while the volume of the second audio signal is positively correlated with the vehicle's current speed. Within the second speed range, by superimposing the two audio signals and adjusting their volumes according to vehicle speed, the layering of the simulated engine sound is enhanced, further improving the user's driving experience.

[0009] In one possible implementation, after detecting that the vehicle's current speed is within a first speed range, playing a first audio signal includes: after detecting that the vehicle's current speed is within a first speed range, determining a first audio signal corresponding to the first speed range; generating a first audio signal based on the first audio signal; and playing the first audio signal.

[0010] Based on the aforementioned technical means, the corresponding audio signal is selected according to the vehicle's current speed, making the generated audio more in line with the vehicle speed, thereby improving the effect of simulated sound waves.

[0011] In one possible implementation, before activating the sound simulation function, the method further includes: acquiring audio signals corresponding to each speed range and storing the audio signals corresponding to each speed range.

[0012] Based on the above technical means, before activating the sound wave simulation function, the audio signals corresponding to each speed range are acquired and stored, so that the corresponding audio can be directly generated using the audio signals in the subsequent sound wave simulation process, thereby improving the working efficiency of the sound wave simulation.

[0013] According to a second aspect of this application, a sound simulation device is provided, comprising: an acquisition module for acquiring the current speed of a vehicle after activating the sound simulation function; a processing module for playing a first audio signal after detecting that the current speed of the vehicle is within a first speed range; and the processing module further for playing a second audio signal after detecting that the current speed of the vehicle has reached the lower limit of a second speed range, and adjusting the volume of the first audio signal according to the current speed of the vehicle until the playback of the first audio signal stops, wherein the lower limit of the second speed range is greater than or equal to the upper limit of the first speed range.

[0014] In one possible implementation, when the vehicle's current speed is within a first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed; when the vehicle's current speed is within a second speed range, the volume of the first audio signal is negatively correlated with the vehicle's current speed, and the volume of the second audio signal is positively correlated with the vehicle's current speed.

[0015] In one possible implementation, the processing module is specifically configured to: after detecting that the current speed of the vehicle is within a first speed range, determine a first audio signal corresponding to the first speed range; generate a first audio signal based on the first audio signal, and play the first audio signal.

[0016] In one possible implementation, the acquisition module is further configured to: acquire audio signals corresponding to each speed range and store the audio signals corresponding to each speed range.

[0017] According to a third aspect provided in this application, a vehicle is provided, comprising: a processor; a memory for storing processor-executable instructions; wherein the processor is configured to execute instructions to implement the method of the first aspect described above and any possible implementation thereof.

[0018] According to a fourth aspect provided in this application, a computer-readable storage medium is provided that, when the instructions in the computer-readable storage medium are executed by a processor of a vehicle, enables the vehicle to perform the methods described in the first aspect and any possible implementation thereof.

[0019] According to the fifth aspect provided in this application, a computer program product is provided, the computer program product including computer instructions that, when executed on a vehicle, cause the vehicle to perform the method described in the first aspect and any possible implementation thereof.

[0020] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0021] (1) When the vehicle’s current speed is within the first speed range, the first audio corresponding to the first speed range is played to achieve the effect of simulating sound waves. When the vehicle’s current speed reaches the lower limit of the second speed range, the second audio is played.

[0022] (2) When the vehicle's current speed is within the first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed, allowing the audio volume to be adjusted according to the vehicle speed, providing users with a more realistic driving experience.

[0033] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0034] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0035] As described in the background section, the simulated engine sound function currently equipped in new energy vehicles is too monotonous. It can only play the audio of the engine sound or adjust the volume of the audio according to the current speed of the vehicle. It lacks a sense of layering and fails to gain user approval.

[0036] To address the aforementioned issues, this application provides a method for simulating engine sound. When the vehicle's current speed falls within a first speed range, a first audio signal corresponding to that first speed range is played to simulate engine sound. Furthermore, when the vehicle's current speed reaches the lower limit of a second speed range, a second audio signal is played. The volume of the first audio signal corresponding to the first speed range is adjusted according to the vehicle's current speed, thereby achieving the superposition of the two audio signals and enhancing the layering of the simulated engine sound, thus improving the user's driving experience.

[0037] like Figure 1 As shown, this application provides a method for simulating sound waves, which includes the following steps:

[0038] S101. After enabling the sound simulation function, obtain the vehicle's current speed.

[0039] In some embodiments, when a user activates the vehicle's sound simulation function, the vehicle obtains its current speed via a speed sensor.

[0040] Optionally, users can activate the vehicle's sound simulation function by voice activation, or by clicking the sound simulation function icon on the vehicle's infotainment screen.

[0041] S102. After detecting that the vehicle's current speed is within the first speed range, play the first audio.

[0042] Optional, such as Figure 2As shown, after detecting that the vehicle's current speed is within the first speed range, the first audio is played. This can be specifically implemented through the following steps:

[0043] S1021. After detecting that the vehicle's current speed is within the first speed range, determine the first audio signal corresponding to the first speed range.

[0044] It should be noted that before activating the sound simulation function, the vehicle acquires and stores the audio signals corresponding to each speed range.

[0045] For example, before activating the simulated engine sound power supply, staff upload the audio signals corresponding to different speed ranges to the vehicle's storage device. Alternatively, before activating the simulated engine sound power supply, the vehicle downloads the audio signals corresponding to different speed ranges to its storage device via the network.

[0046] In some embodiments, after detecting that the vehicle's current speed is within a first speed range, the audio signal corresponding to the first speed range is selected by searching for audio signals corresponding to different speed ranges stored in the vehicle's storage device. Alternatively, after detecting that the vehicle's current speed is within the first speed range, the vehicle's storage device actively sends the audio signal corresponding to the first speed range to the vehicle.

[0047] For example, the first speed range can be 20km / h to 30km / h. After the sound simulation function is turned on, the current speed of the vehicle is 25km / h, which is within the first speed range. The audio signal corresponding to the first speed range is signal A. Therefore, signal A in the vehicle's storage device is selected to complete the playback of the subsequent first audio.

[0048] In this way, before activating the sound wave simulation function, the audio signals corresponding to each speed range are acquired and stored, so that the corresponding audio can be directly generated using the audio signals during the subsequent sound wave simulation process, thereby improving the efficiency of the sound wave simulation.

[0049] S1022. Generate a first audio signal based on the first audio signal and play the first audio signal.

[0050] Optionally, after acquiring the first audio signal, the first audio signal is imported into a digital signal processing (DSP) chip, so that the DSP chip generates the first audio based on the first audio signal, and then plays the first audio through the vehicle's audio system. Alternatively, the vehicle's storage device stores audio corresponding to each speed range. After detecting that the vehicle's current speed is within the first speed range, the corresponding first audio can be directly selected from the vehicle's storage device and then played through the vehicle's audio system.

[0051] In this way, the corresponding audio signal is selected based on the vehicle's current speed, making the generated audio more in line with the vehicle speed, thereby improving the effect of the simulated sound.

[0052] In some embodiments, when the vehicle's current speed is within a first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed.

[0053] For example, when the vehicle's current speed is within the first speed range, the volume of the first audio increases as the vehicle's current speed increases and decreases as the vehicle's current speed decreases. When the vehicle's current speed reaches the upper limit of the first speed range, the volume of the first audio also reaches its maximum value.

[0054] S103. After detecting that the vehicle's current speed has reached the lower limit of the second speed range, play the second audio and adjust the volume of the first audio according to the vehicle's current speed until the first audio stops playing.

[0055] Among them, the lower limit of the second speed range is greater than or equal to the upper limit of the first speed range.

[0056] Optional, such as Figure 3 As shown, after detecting that the vehicle's current speed has reached the lower limit of the second speed range, the second audio is played. This can be specifically implemented through the following steps:

[0057] S1031. After detecting that the current speed of the vehicle has reached the lower limit of the second speed range, determine the second audio signal corresponding to the second speed range.

[0058] S1032. Generate a second audio signal based on the second audio signal and play the second audio signal.

[0059] The specific descriptions of S1031-S1032 can be found in the specific descriptions of S1021-S1022 above, and will not be repeated here.

[0060] In some embodiments, when the vehicle's current speed is within a second speed range, the volume of the first audio signal is negatively correlated with the vehicle's current speed, and the volume of the second audio signal is positively correlated with the vehicle's current speed.

[0061] For example, when the vehicle's current speed is within the second speed range, the volume of the first audio signal decreases as the vehicle's current speed increases and increases as the vehicle's current speed decreases. When the vehicle's current speed reaches the upper limit of the second speed range, the volume of the first audio signal decreases to 0, i.e., playback of the first audio signal stops. The volume of the second audio signal increases as the vehicle's current speed increases and decreases as the vehicle's current speed decreases. When the vehicle reaches the upper limit of the second speed range, the volume of the second audio signal also reaches its maximum value.

[0062] In another example, the first speed range is 20 km / h to 30 km / h, and the second speed range is 30 km / h to 40 km / h. When the vehicle's current speed reaches the lower limit of the second speed range, i.e., 30 km / h, the second audio is played. Within the second speed range, the volume of the first audio decreases as the vehicle's current speed increases, while the volume of the second audio increases as the vehicle's current speed increases.

[0063] In this way, when the vehicle's current speed is within the first speed range, the first audio corresponding to the first speed range is played to simulate the sound wave effect. When the vehicle's current speed reaches the lower limit of the second speed range, the second audio is played, and the volume of the first audio corresponding to the first speed range is adjusted according to the vehicle's current speed. This achieves the superposition of the two audio segments, thereby improving the layering of the simulated sound wave and enhancing the user's driving experience.

[0064] It is understandable that the above description of the sound simulation method assumes the vehicle as a whole is accelerating, i.e., accelerating from a certain speed in the first speed range to a certain speed in the second speed range. The sound simulation method provided in this application embodiment is still applicable when the vehicle is decelerating. Figure 4 The diagram illustrates the method for simulating the sound waves provided in this application, taking the entire vehicle as the deceleration process as an example. The specific steps are as follows:

[0065] S401. After enabling the sound simulation function, obtain the vehicle's current speed.

[0066] S402. After detecting that the vehicle's current speed is within the second speed range, play the second audio.

[0067] S403. After detecting that the vehicle's current speed has reached the upper limit of the first speed range, play the first audio and adjust the volume of the first audio according to the vehicle's current speed until the second audio stops playing.

[0068] The specific descriptions of S401-S403 are the same as those of S101-S103, and will not be repeated here.

[0069] Figure 5 This is a schematic diagram illustrating the structure of a sound wave simulation device according to an exemplary embodiment. See also: Figure 5 The sound simulation device 50 includes an acquisition module 501 and a processing module 502.

[0070] The acquisition module 501 is used to acquire the current speed of the vehicle after the sound simulation function is enabled.

[0071] The processing module 502 is used to play the first audio after detecting that the current speed of the vehicle is within the first speed range;

[0072] The processing module 502 is further configured to play a second audio after detecting that the current speed of the vehicle has reached the lower limit of the second speed range, and adjust the volume of the first audio according to the current speed of the vehicle until the first audio stops playing, wherein the lower limit of the second speed range is greater than or equal to the upper limit of the first speed range.

[0073] In some embodiments, when the vehicle's current speed is within a first speed range, the volume of the first audio signal is positively correlated with the vehicle's current speed; when the vehicle's current speed is within a second speed range, the volume of the first audio signal is negatively correlated with the vehicle's current speed, and the volume of the second audio signal is positively correlated with the vehicle's current speed.
