Description

Sound wave playing method, device and intelligent driving equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on November 22, 2023, with application number 202311572878.8 and application name “A sound wave playback method, device and intelligent driving device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicles, and more specifically, to a sound wave playback method, device, and intelligent driving equipment. Background Art

[0003] Although automobiles are developing in the direction of new energy, due to the lack of engine cylinders and exhaust physical systems in new energy vehicles, users lack perceptible sound feedback following the pedals when driving in the car, which actually greatly affects the driver's immersive driving experience. To address this, the vehicle's driving parameters are usually obtained to simulate the sound waves, and the car's speakers are used to actively emit sound waves to improve the user experience. However, the current sound wave simulation effect is single and can only meet some application scenarios. It cannot match the user's operation, which in turn leads to a decline in the user's driving experience. Based on this, how to improve the sound wave playback effect so that the sound wave can match the user's operation has become a technical problem that needs to be solved urgently.

[0004] Summary of the Invention

[0007] In an embodiment of the present application, the vehicle can play the charging sound when the vehicle speed is 0 and the depth of the user's simultaneous pressing of the accelerator pedal and the brake pedal meets the conditions, so that the user can feel the sound of the engine even when driving a new energy vehicle, thereby enhancing the user's immersion and driving pleasure during the driving process and helping to improve the user experience.

[0008] In addition, the charging sound wave is not simulated, but a preset sound wave, so the charging sound wave effect will be more realistic. At the same time, by setting the trigger condition to play the charging sound wave, the timing of playing the charging sound wave can be more consistent with the user's operation.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: determining the duration during which the brake pedal's depression depth is greater than the first threshold and the accelerator pedal's depression depth is greater than the second threshold; when the duration is less than n seconds, where n>0, the method further includes: adjusting the pitch of the charging sound upward.

[0010] In an embodiment of the present application, the vehicle can adjust the tone of the charging sound according to the duration that the user simultaneously steps on the accelerator pedal and the brake pedal, so that the user can better feel the changes in the charging sound, thereby enhancing the user's immersion and driving pleasure during the driving process, and helping to improve the user experience.

[0014] In an embodiment of the present application, the vehicle can adjust the tone of the charging sound according to the duration that the user simultaneously steps on the accelerator pedal and the brake pedal, so that the user can better feel the changes in the charging sound, thereby enhancing the user's immersion and driving pleasure during the driving process, and helping to improve the user experience.

[0017] In an embodiment of the present application, when the vehicle switches from a state where both the accelerator pedal and the brake pedal are stepped on to a state where the brake pedal is released, a catapult sound can be played, thereby enhancing the user's immersion and driving pleasure during driving and helping to improve the user experience.

[0018] In combination with the first aspect, in certain implementations of the first aspect, before the brake pedal is released, the depression depth of the accelerator pedal is greater than a third threshold, and the third threshold is greater than the second threshold.

[0019] In an embodiment of the present application, when the vehicle switches from a state where both the accelerator pedal and the brake pedal are stepped on to a state where the brake pedal is released and the accelerator pedal is deeply stepped on, a catapult sound can be played, which is more realistic, enhances the user's immersion and driving pleasure during the driving process, and helps to improve the user experience.

[0020] In combination with the first aspect, in certain implementations of the first aspect, after playing the ejection sound, the method further includes: when it is determined that the vehicle is in an accelerating state based on the vehicle speed and / or power speed, playing an acceleration sound.

[0044] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0045] Figure 1 is a functional block diagram of an intelligent driving device provided in an embodiment of the present application. As shown in Figure 1, the intelligent driving device 100 may include a perception system 120, a display device 130 and a computing platform 150, wherein the perception system 120 may include several sensors for sensing information about the environment surrounding the intelligent driving device 100. For example, the perception system 120 may include a positioning system, and the positioning system may be a global positioning system (GPS), or a Beidou system or other positioning system. For another example, the perception system 120 may also include one or more of an inertial measurement unit (IMU), a laser radar, a millimeter wave radar, an ultrasonic radar, and a camera device. Among them, the camera device may include a camera device arranged at a rearview mirror, and the camera device may include but is not limited to a fisheye camera and a wide-angle camera.

[0046] The display device 130 in the cockpit is mainly divided into two categories: the first is the vehicle-mounted display screen; the second is a projection display screen, such as a head-up display (HUD). The vehicle-mounted display screen is a physical display screen and an important component of the in-vehicle infotainment system. Multiple displays can be installed in the cockpit, such as the digital instrument panel and the central control screen. A head-up display, also known as a head-up display system, is primarily used to display driving information such as speed and navigation on a display device in front of the driver (such as the windshield). This reduces the driver's gaze shift time, avoids pupil changes caused by the driver's gaze shift, and improves driving safety and comfort. HUDs include, for example, combined head-up display (C-HUD) systems, windshield head-up display (W-HUD) systems, and augmented reality head-up display (AR-HUD) systems. The display device may also include a human-machine interface (HMI) to prompt the user when switching between planning modes.

[0047] Some or all functions of the intelligent driving device 100 can be controlled by a computing platform 150. The computing platform 150 may include processors 151 to 15n. A processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with the ability to read and execute instructions, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration file to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, the processor may also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 150 may also include a memory for storing instructions, and some or all of the processors 151 to 15n may call the instructions in the memory to implement corresponding functions.

[0048] The intelligent driving devices involved in this application may include road vehicles, water vehicles, air vehicles, industrial equipment, agricultural equipment, or entertainment equipment, etc. For example, the intelligent driving device can be a vehicle, which is a vehicle in a broad sense, and can be a vehicle (such as a commercial vehicle, a passenger car, a motorcycle, a flying car, a train, etc.), an industrial vehicle (such as a forklift, a trailer, a tractor, etc.), an engineering vehicle (such as an excavator, a bulldozer, a crane, etc.), agricultural equipment (such as a mower, a harvester, etc.), amusement equipment, a toy vehicle, etc. The embodiment of this application does not specifically limit the type of vehicle. For another example, the vehicle can be a vehicle such as an airplane or a ship. The following is an example of an intelligent driving device being a vehicle.

[0049] Although automobiles are trending toward new energy vehicles, the lack of engine cylinders and exhaust physics means users lack perceptible acoustic feedback from pedal strokes while driving, significantly impacting the driver's immersive driving experience. To address this, sound simulation is often used, using the car's speakers to actively generate sound waves to enhance the user experience. However, current sound simulations offer limited effectiveness, only meeting certain application scenarios and failing to align with user input, resulting in a diminished driving experience.

[0050] Currently, it's possible to simulate car noise using sine waves. The basic principle of this technology is to convert the car engine's sound signal into a sine wave and then adjust factors such as the sine wave's frequency, amplitude, and phase to simulate the car's noise. Specifically, this method first requires collecting the car engine's sound signal, analyzing and processing it. Then, leveraging the characteristics of sine waves, these signals are converted into sine waves. The sine wave is then adjusted and simulated using computer software or hardware. Finally, the simulated noise is played through speakers or audio equipment.

[0051] However, due to the relatively simple waveform of the sine wave, the simulated sound waves often lack the complexity and variability of real car sounds.

[0052] Currently, it's also possible to simulate car noise using audio slicing and pitch shifting technology. The basic principle of this technology is to convert the car engine sound signal into audio segments and then pitch-shift each audio segment. Specifically, this sound simulation method first requires collecting the car engine sound signal, analyzing and processing it. Then, using the characteristics of audio slicing and pitch shifting technology, these sound signals are converted into audio segments, and the pitch of each audio segment is shifted. During this process, the effect of the simulated sound can be changed by adjusting the pitch shifting parameters. Finally, the simulated sound is played through speakers or audio equipment.

[0053] However, since the same pitch changes in all frequency bands during audio slicing, it is impossible to achieve different pitch changes in different frequency bands. Therefore, it is only suitable for sound wave effects with uniform speed and small pitch variation span.

[0054] Currently, car noise simulation can also be achieved through audio particle extraction technology. The basic principle of this technology is to convert the car engine sound signal into audio particles and extract features from each audio particle to obtain a characteristic representation of the audio file. Machine learning algorithms are then used to classify or identify the extracted features to produce a simulated car noise. Specifically, this noise simulation method first requires collecting the car engine sound signal, analyzing and processing it. Then, leveraging the characteristics of audio particle extraction technology, these sound signals are converted into audio particles, and features are extracted from each audio particle. Different feature extraction methods can be used in this process, such as spectral features, time domain features, etc. Finally, machine learning algorithms are used to classify or identify the extracted features to produce a simulated car noise.

[0055] However, when audio particle extraction technology simulates car sounds, it is bound to the car speed, and the acceleration effect is fixed.

[0056] The above-mentioned sound wave simulation method cannot be applied to all user operations, so the generated sound waves may not match the user's actual operation, which in turn leads to a decline in user experience.

[0057] Based on this, the embodiment of the present application provides a sound wave playback method, which adds charging sound effects and ejection sound effects, enriches the sound wave playback effect, and helps to improve the user experience.

[0058] FIG2 shows a schematic flow chart of a sound wave playback method provided by an embodiment of the present application. The method shown in FIG2 can be executed by the intelligent driving device 100 shown in FIG1 . The following description is based on an example in which the intelligent driving device 100 is executed and the intelligent driving device is a vehicle. As shown in FIG2 , the method includes:

[0059] S201, determining the depression depth of the brake pedal and the depression depth of the accelerator pedal.

[0060] In some embodiments, the vehicle may obtain depth information of the brake pedal and depth information of the accelerator pedal, wherein the depth information of the brake pedal is used to indicate the depression depth of the brake pedal, and the depth information of the accelerator pedal is used to indicate the depression depth of the accelerator.

[0061] In some embodiments, the depth information of the brake pedal and the depth information of the accelerator pedal can be represented by controller area network (CAN) signals. It is easy to understand that different CAN signal values ​​represent different pedaling depths.

[0062] For example, the brake pedal depth information is CAN signal #1, which indicates the brake pedal's depression depth. The accelerator pedal depth information is CAN signal #2, which indicates the accelerator pedal's depression depth. A value of 1 in CAN signal #1 corresponds to a brake pedal depression depth of 1%. A value of 50 in CAN signal #2 corresponds to a accelerator pedal depression depth of 50%.

[0063] It should be understood that the numerical values ​​involved in the above examples are only examples and should not be understood as specific limitations on the embodiments of the present application.

[0064] It should also be understood that the use of percentages to express the trampling depth in the above examples is merely an example and should not be construed as a specific limitation on the embodiments of the present application. For example, in other embodiments of the present application, the trampling depth may also be expressed in units of length. For example, the trampling depth may be 1 cm, 2 cm, etc.

[0065] In some embodiments, the vehicle can obtain brake pedal depth information and accelerator pedal depth information, and then determine the brake pedal depression depth and accelerator pedal depression depth based on the brake pedal depth information and accelerator pedal depth information. In other words, the vehicle can directly determine the brake pedal depression depth and accelerator pedal depression depth.

[0066] In some embodiments, the depth information of the brake pedal and the depth information of the accelerator pedal can be obtained when the vehicle is in an initialization startup state.

[0067] It is understandable that when the vehicle is in the initialization start state, the vehicle speed is 0 km / h.

[0068] S202: Determine whether the brake pedal's depression depth is greater than a first threshold, and whether the accelerator pedal's depression depth is greater than a second threshold.

[0069] After determining the brake pedal and accelerator pedal depression depths, the vehicle can determine whether the brake pedal depression depth is greater than a first threshold and whether the accelerator pedal depression depth is greater than a second threshold. If both the brake pedal depression depth and the accelerator pedal depression depth are greater than the first threshold and the second threshold, step S203 can be performed; otherwise, no action is taken. In other words, step S203 is only performed if both the brake pedal depression depth and the accelerator pedal depression depth are greater than their corresponding thresholds.

[0070] In some embodiments, the first threshold and the second threshold may be the same.

[0071] In some embodiments, the first threshold and the second threshold may be different.

[0072] As described above, the brake pedal and accelerator pedal depression depths determined by the vehicle can be directly represented by their respective depression depths or indirectly represented by their respective depth information values. Therefore, the first threshold and the second threshold can correspond to either the depression depth or the depth information value.

[0073] For example, if the first threshold and the second threshold are the same, that is, 10, i.e., the first threshold and the second threshold correspond to depth information values, the vehicle determines that the depth information value of the brake pedal is 20 and the depth information value of the accelerator pedal is 25, and both are greater than 10, then the vehicle can proceed to S203.

[0074] For another example, assuming the first threshold and the second threshold are the same, that is, the first threshold and the second threshold are 10%, that is, the first threshold and the second threshold correspond to the pedaling depth. The vehicle determines that the value of the brake pedal depth information is 20, and the value of the accelerator pedal depth information is 25. The vehicle can determine that the brake pedal pedal pedaling depth is 20% based on the brake pedal depth information, and the accelerator pedal pedal pedaling depth is 25% based on the accelerator pedal depth information. If both values ​​are greater than 10, the vehicle can proceed to S203.

[0075] S203, play charging sound wave.

[0076] The vehicle determines that the brake pedal's depression depth is greater than a first threshold and the accelerator pedal's depression depth is greater than a second threshold, and can play a charging sound.

[0077] In some embodiments, the charged sound wave may be a preset sound wave.

[0078] For example, the charging sound wave may be preset by the vehicle manufacturer or by the manufacturer providing the vehicle's operating system when the vehicle leaves the factory.

[0079] Exemplarily, the charging sound wave may be uploaded by a user.

[0080] For example, the vehicle has multiple charging sound waves preset, and the vehicle can determine the corresponding sound wave according to the user's selection.

[0081] For example, the vehicle has pre-set charging sound #1 and charging sound #2. The user can select charging sound #1 as the charging sound to be played, so that the vehicle can play charging sound #1 when it determines that the value of the depth information of the brake pedal is greater than the first threshold and the value of the depth information of the accelerator pedal is greater than the second threshold.

[0082] It can be understood that the charging sound wave reflects the sound of the engine speed of a vehicle equipped with an engine, which increases from slow to fast when both the accelerator and brake pedals are pressed and the vehicle is in place. This charging sound wave allows users to feel the engine sound even when driving a new energy vehicle, enhancing the user's driving immersion and helping to improve the user experience.

[0083] In an embodiment of the present application, the vehicle can play the charging sound when the vehicle speed is 0 and the depth of the user's simultaneous pressing of the accelerator pedal and the brake pedal meets the conditions, so that the user can feel the sound of the engine even when driving a new energy vehicle, thereby enhancing the user's immersion and driving pleasure during the driving process and helping to improve the user experience.

[0084] In some embodiments, since the charging sound wave is preset, when playing the charging sound wave, the surrounding sound audio effect component can be used to play the charging sound wave.

[0085] In some embodiments, the method further comprises:

[0086] S204: Determine a duration during which the brake pedal's depression depth is greater than a first threshold and the accelerator pedal's depression depth is greater than a second threshold.

[0087] It should be noted that there is no specific order for S203 and S204; the vehicle can execute S203 and S204 simultaneously. That is, when the vehicle plays the charging sound, it will calculate the duration of time that the brake pedal's depression depth exceeds the first threshold and the accelerator pedal's depression depth exceeds the second threshold.

[0088] According to the duration, there are several possible situations.

[0089] When the duration is less than n seconds, the method further includes:

[0090] S205, adjust the pitch of the charging sound wave upwards.

[0091] When the vehicle detects that the brake pedal's depression depth is greater than a first threshold and the accelerator pedal's depression depth is greater than a second threshold for less than n seconds, the pitch of the charging sound can be adjusted upward while playing the charging sound, where n>0.

[0092] In some embodiments, it can be understood that the multiple by which the pitch of the charging sound wave is adjusted upward may be related to the duration.

[0093] For example, if the duration is 1 second, the pitch of the charging sound wave will be adjusted upward by 1.5 times.

[0094] For another example, taking the duration as 2 seconds, when the duration reaches 1 second, the pitch of the charging sound wave is adjusted upward by 2 times.

[0095] In some embodiments, n=3.

[0096] When the duration is greater than or equal to n seconds and less than m seconds, the method further includes:

[0097] S206, adjusting the pitch of the charging sound wave upward within n seconds, so that when the duration reaches n seconds, the pitch of the charging sound wave is adjusted to q times, and the pitch of the charging sound wave is kept adjusted to q times within n seconds to m seconds.

[0098] When the vehicle detects that the brake pedal's depression depth is greater than a first threshold and the accelerator pedal's depression depth is greater than a second threshold for a duration greater than or equal to n seconds and less than m seconds, the pitch of the charging sound wave can be adjusted upward first. When n seconds pass, the pitch of the charging sound wave is adjusted upward by q times, and after n seconds, the pitch of the charging sound wave is maintained at the pitch corresponding to n seconds, where m>0, q>0.

[0099] In some embodiments, m=10.

[0100] When the duration is greater than or equal to m seconds, the method further includes:

[0101] S207, adjusting the pitch of the charging sound wave upward within n seconds, so that when the duration reaches n seconds, the pitch of the charging sound wave is adjusted to q times, and the pitch of the charging sound wave is kept adjusted to q times within n seconds to m seconds.

[0102] S208, when the duration reaches m seconds, stop playing the charging sound wave with the pitch adjusted to q times.

[0103] When the vehicle detects that the brake pedal's depression depth is greater than a first threshold and the accelerator pedal's depression depth is greater than a second threshold for a duration greater than or equal to m seconds, the pitch of the charging sound wave can be adjusted upward first. When n seconds pass, the pitch of the charging sound wave is adjusted upward by q times, and after n seconds, the pitch of the charging sound wave is maintained at the pitch corresponding to n seconds. Then, when the duration reaches m seconds, the charging sound wave can be stopped.

[0104] It is understandable that when the vehicle detects that the accelerator pedal or brake pedal is released, the charging sound can be stopped.

[0105] In an embodiment of the present application, the vehicle can adjust the tone of the charging sound according to the duration that the user simultaneously steps on the accelerator pedal and the brake pedal, so that the user can better feel the changes in the charging sound, thereby enhancing the user's immersion and driving pleasure during the driving process, and helping to improve the user experience.

[0106] In some embodiments, while the vehicle is playing the charging sound, or after the charging sound stops playing, wherein after the charging sound is played, the brake pedal and the accelerator pedal are in a stepped state, the method further includes:

[0107] S209: Detecting that the brake pedal is released, playing the ejection sound.

[0108] For example, when the vehicle is playing a charging sound, that is, the brake pedal is depressed to a depth greater than a first threshold and the accelerator pedal is depressed to a depth greater than a second threshold, and it is detected that the brake pedal is released, the vehicle can play a launching sound.

[0109] For another example, if the vehicle stops playing the charging sound, but the brake pedal's depression depth is still greater than the first threshold and the accelerator pedal's depression depth is still greater than the second threshold, the vehicle can play the launch sound when the brake pedal is released. In other words, if the brake pedal's depression depth is greater than the first threshold and the accelerator pedal's depression depth is greater than the second threshold for more than m seconds, the vehicle stops playing the charging sound after m seconds. When the brake pedal is released after m seconds, the vehicle can play the launch sound.

[0110] It can be understood that the ejection sound reflects the sound made by the engine when a vehicle equipped with an engine is ejected and started.

[0111] In an embodiment of the present application, when the vehicle switches from a state where both the accelerator pedal and the brake pedal are stepped on to a state where the brake pedal is released, a catapult sound can be played, thereby enhancing the user's immersion and driving pleasure during driving and helping to improve the user experience.

[0112] In some embodiments, before the brake pedal is released, the depression depth of the accelerator pedal is greater than a third threshold, and the third threshold is greater than the second threshold.

[0113] In an embodiment of the present application, when the vehicle switches from a state where both the accelerator pedal and the brake pedal are stepped on to a state where the brake pedal is released and the accelerator pedal is deeply stepped on, a catapult sound can be played, which is more realistic, enhances the user's immersion and driving pleasure during the driving process, and helps to improve the user experience.

[0114] For example, when the vehicle is playing a charging sound, the brake pedal is depressed at a depth of depth #1, which is greater than a first threshold, and the accelerator pedal is depressed at a depth of depth #2, which is greater than a third threshold. When the brake pedal is detected to be released, the vehicle can play a launch sound.

[0115] For another example, the vehicle is playing the charging sound, where the brake pedal is depressed at a depth of depth #1, which is greater than the first threshold, and the accelerator pedal is depressed at a depth of depth #2, which is less than the third threshold but greater than the second threshold. At this time, it is detected that the brake pedal is released, and the vehicle will not play the ejection sound.

[0116] In some embodiments, the ejection sound wave may also be a preset sound wave.

[0117] When the brake pedal is released, the vehicle begins to accelerate because the accelerator pedal is still depressed. In some embodiments, after playing the launch sound, the method further includes: playing the acceleration sound when it is determined that the vehicle is in an accelerating state based on the vehicle speed and / or power speed.

[0118] The vehicle can obtain the vehicle speed and / or power speed, and play the acceleration sound when it is determined that the vehicle is in an accelerating state based on the vehicle speed and / or power speed.

[0119] It can be understood that the acceleration sound reflects the sound made by the engine when a vehicle equipped with an engine accelerates.

[0120] In an embodiment of the present application, when the vehicle is in an accelerating state, the acceleration sound can be played, which is more realistic, enhances the user's immersion and driving pleasure during the driving process, and helps to improve the user experience.

[0121] In addition, since the vehicle plays the acceleration sound after determining that the vehicle has actually started to accelerate, it can better meet the user's feelings.

[0122] In some embodiments, the acceleration sound wave may also be a preset sound wave.

[0123] In some embodiments, the method further includes: when it is detected that a first preset condition is met, stopping playing the acceleration sound.

[0124] In the embodiment of the present application, the first preset condition is not specifically limited, and several possible implementation methods are exemplarily introduced below.

[0125] Exemplarily, the first preset condition is that the vehicle switches from an accelerating state to a constant speed state.

[0126] For example, the first preset condition is that the duration of playing the acceleration sound wave is greater than a fourth threshold value. For example, the fourth threshold value is 25 seconds.

[0127] When the accelerator pedal is released and the brake pedal is depressed, the vehicle begins to decelerate. In some embodiments, the method further includes:

[0128] When the vehicle is determined to be in a deceleration state based on the vehicle speed and / or power speed, a deceleration sound is played.

[0129] The vehicle can obtain the vehicle speed and / or power speed, and play the deceleration sound when it is determined that the vehicle is in a deceleration state based on the vehicle speed and / or power speed.

[0130] It can be understood that the deceleration sound reflects the sound made by the engine when a vehicle equipped with an engine decelerates.

[0131] In an embodiment of the present application, when the vehicle is in a deceleration state, the deceleration sound can be played, which is more realistic, enhances the user's immersion and driving pleasure during the driving process, and helps to improve the user experience.

[0132] In addition, since the vehicle plays the deceleration sound after determining that the vehicle has actually started to decelerate, it can better meet the user's feelings.

[0133] In some embodiments, the deceleration sound wave may also be a preset sound wave.

[0134] In some embodiments, the method further includes: stopping playing the deceleration sound when it is detected that a second preset condition is met.

[0135] In the embodiment of the present application, the second preset condition is not specifically limited, and several possible implementation methods are exemplarily introduced below.

[0136] Exemplarily, the second preset condition is that the vehicle switches from a deceleration state to a constant speed state.

[0137] Exemplarily, the second preset condition is that the duration of playing the deceleration sound is greater than the fifth threshold.

[0138] Exemplarily, the second preset condition is that the vehicle speed is reduced to 0.

[0139] When the accelerator pedal is released and the brake pedal is stepped on, the vehicle starts to decelerate. When the vehicle speed drops to less than a sixth threshold, in some embodiments, the method further includes: detecting that the brake pedal is released and the accelerator pedal is stepped on and the stepping depth is greater than a seventh threshold, and playing a launch sound.

[0140] For example, when the vehicle speed decreases to 10 km / h, the vehicle detects that the user releases the brake pedal and steps on the accelerator pedal with a stepping depth greater than 60%, and a ejection sound wave can be played.

[0141] In an embodiment of the present application, when the vehicle speed is slow and it is detected that the user has stepped deeply on the accelerator pedal, a catapult sound can be played, which is more realistic, enhances the user's immersion and driving pleasure during driving, and helps to improve the user experience.
