It should be understood that the preferred embodiments are only for illustrating the present application, not for limiting the scope of protection of the present application.

[0027] It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present application in a schematic manner, and therefore the illustrations only show components related to the present application rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0028] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application. However, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present application difficult to understand.

[0029] First of all, it should be noted that in the automotive field, Chime is usually used as an in-car audio prompt signal to provide timely and accurate information feedback to drivers and passengers. As a prompt sound, Chime has multiple functions in the car, aiming to improve driving convenience, safety and overall user experience.

[0030] Figure 1 It is a schematic diagram of an exemplary system architecture shown in an exemplary embodiment of the present application.

[0031] Reference Figure 1As shown, the system architecture may include a data acquisition device 101 and a computer device 102. The computer device 102 may be at least one of a desktop graphics processing unit (GPU) computer, a GPU computing cluster, a neural network computer, etc. The data acquisition device 101 is used to collect vehicle operation data and driving environment data of the target vehicle. The vehicle operation data includes driving speed and direction information, and the driving environment data includes road speed limit information, noise information, and light intensity information. In this embodiment, after the data acquisition device 101 obtains the vehicle operation data and driving environment data of the target vehicle, it provides the vehicle operation data and driving environment data to the computer device 102 for processing. Relevant technicians can use the computer device 102 to pre-set the playback-related index of the target vehicle, and determine the index-related parameters corresponding to the playback-related index, as well as the influence relationship between the playback-related index and the index-related parameters, collect data from the target vehicle according to the index-related parameters, obtain the current parameter value corresponding to the index-related parameter, determine the coefficient of the current parameter value according to the influence relationship, obtain the index coefficient corresponding to the index-related parameter, and calculate according to the index coefficient to obtain the playback index value corresponding to the playback-related index, and control the target vehicle to adjust and play the sound data to be played according to the playback index value. It should be noted that the data acquisition device 101 and the computer device 102 provided in this embodiment are only an example and should not bring any limitation to the functions and scope of use of the embodiments of the present application.

[0032] It should be noted that the sound adjustment method provided in the embodiment of the present application is generally executed by the computer device 102 , and accordingly, the sound adjustment device is generally disposed in the computer device 102 .

[0033] Figure 2 is a flow chart of a sound adjustment method shown in an exemplary embodiment of the present application. The sound adjustment method can be executed by a computing and processing device. The computing and processing device can be Figure 1 The computer device 102 shown in FIG. Figure 2 As shown, the sound adjustment method at least includes steps S210 to S240, which are described in detail as follows:

[0034] In step S210, the playback related index of the target vehicle is preset, and the index related parameters corresponding to the playback related index and the influence relationship between the playback related index and the index related parameters are determined.

[0035] Among them, the influence relationship includes a positive correlation or a negative correlation.

[0036] In one embodiment of the present application, a sound playback request is received, the sound playback request includes a sound data identifier; the sound data to be played corresponding to the sound data identifier is stored in a sound playback queue to obtain the sound data to be played from the sound playback queue; the currently playing sound data is obtained; if the priority of the sound data to be played is lower than or equal to the priority of the currently playing sound data, the currently playing sound data continues to be played; if the priority of the sound data to be played is higher than the priority of the currently playing sound data, the currently playing sound data is stopped.

[0037] In this embodiment, taking the Chime prompt sound as an example, the sound adjustment method is completed by an intelligent acoustic feedback system used in the field of vehicle technology. The intelligent acoustic feedback system includes a perception module, which opens three threads, one for receiving sound playback requests from other modules in real time. After receiving the sound playback request, the sound data to be played corresponding to the sound data identifier in the sound playback request will be stored in the sound playback queue, so that another thread can obtain the sound to be played, that is, the sound data to be played, from the sound playback queue.

[0038] In this embodiment, after obtaining the sound data to be played, it is determined whether there is currently played sound data being played. If not, data collection is performed on the target vehicle according to the index-related parameters to obtain the current parameter value corresponding to the index-related parameters. If there is currently played sound data being played, the priority of the sound data to be played is compared with the priority of the currently played sound data. If the priority of the sound data to be played is lower than or equal to the priority of the currently played sound data, the currently played sound data continues to be played until the currently played sound data is played, and then data collection is performed on the target vehicle according to the index-related parameters; if the priority of the sound data to be played is higher than the priority of the currently played sound data, the playback of the currently played sound data is immediately terminated to collect data on the target vehicle according to the index-related parameters.

[0039] In this embodiment, the priority setting methods include but are not limited to the following three methods: 1. Hard-coded logic, directly setting the priority of the alarm class higher than the priority of the prompt class in the system firmware, and the priority of the prompt class higher than the priority of the background entertainment music. 2. Configurable settings, allowing users to customize the volume and priority of various types of prompt sounds. 3. Event trigger mechanism, when a preset critical safety-related event occurs, such as a collision warning, the system will automatically interrupt or reduce non-important audio output, such as the sound output of multimedia playback (such as podcasts, audio books, movies or videos), to ensure that the alarm prompt sound is clearly heard.

[0040] In step S220, data is collected on the target vehicle according to the index-related parameters to obtain current parameter values ​​corresponding to the index-related parameters.

[0041] In one embodiment of the present application, taking the sound data to be played as Chime prompt sound as an example, the intelligent acoustic feedback system combines the situational awareness function to realize the Chime prompt sound effect with a highly customized and humanized experience, so as to improve the information receiving efficiency and comfort of the driver and passengers. The vehicle data of the target vehicle is obtained through the vehicle sensor, and the vehicle data includes but is not limited to the vehicle operation data and driving environment data. The vehicle operation data includes but is not limited to the driving speed and direction information, and the driving environment data includes but is not limited to the road speed limit information, noise information and light intensity information.

[0042] In this embodiment, the speed of the vehicle can be monitored in real time through the speed sensor built into the target vehicle. When the vehicle speed is fast, the background noise increases, and the system needs to appropriately increase the volume of the Chime prompt sound to overcome noise interference. The increase in vehicle speed will lower the threshold for triggering the Chime, that is, the faster the speed, the earlier the time to trigger warning sounds such as collision warnings, so as to give the driver more sufficient reaction time. In the navigation scenario, when approaching a turn or exit, if the vehicle speed is fast, the timing of playing the Chime prompt sound may be earlier to ensure that the turn instructions are conveyed in time, and the beat and repetition rate of the Chime prompt sound will also increase.

[0043] In this embodiment, the direction information of the target vehicle is monitored by a direction sensor (gyroscope or GPS positioning) to monitor the change of the target vehicle's driving direction, such as when turning, changing lanes, etc., the chime prompt sound of the navigation or driving assistance system is broadcast in time. Although the direction itself does not directly affect the frequency of the chime, in a stereo or multi-channel environment, the difference between the left and right channels or the surround sound effect can be used to simulate the sense of direction of the sound, making it easier for the driver to determine the source of the signal.

[0044] In this embodiment, noise information is monitored by an environmental noise sensor. Environmental noise sensors include but are not limited to external noise sensors and internal noise sensors. The external noise sensor collects noise information from the surrounding environment of the target vehicle, and the internal noise sensor monitors the noise information inside the cabin of the target vehicle. The volume of the Chime prompt sound is dynamically adjusted according to the intensity of the noise information. When the external environmental noise is large, in order to ensure that the Chime prompt sound can be clearly perceived, the system will automatically increase the volume. Conversely, in a quiet environment, the volume is reduced to avoid discomfort or frightening the user.

[0045] In this embodiment, other vehicle data is monitored through other sensors. For example, the light intensity information of the target vehicle's driving environment is monitored through a light sensor, and the volume of the prompt sound is appropriately increased when the driver's attention may be affected at night or in a tunnel; another example is the temperature information of the target vehicle's driving environment is monitored through a temperature sensor, and corresponding adjustments are made considering that the acoustic environment in the car may change due to the closed windows in a cold environment.

[0046] In this embodiment, by integrating the data collected by the above-mentioned sensors, such as driving speed, direction information, noise information of the internal and external environment, etc., the volume, playback frequency and playback timing of the Chime prompt sound are automatically adjusted to ensure that the prompt sound can be effectively perceived under any circumstances.

[0047] In step S230, the coefficient of the current parameter value is determined according to the influence relationship to obtain the index coefficient corresponding to the index-related parameter, and calculation is performed based on the index coefficient to obtain the playback index value corresponding to the playback-related index.

[0048] In one embodiment of the present application, multiple value ranges corresponding to indicator-related parameters are obtained; target coefficients corresponding to each value range are determined according to the influence relationship; and indicator coefficients corresponding to the indicator-related parameters are determined from each target coefficient based on the matching results between the current parameter value and each value range.

[0049] In one embodiment of the present application, multiple historical parameter values ​​and historical coefficients corresponding to each historical parameter value are obtained, wherein an influence relationship exists between the historical parameter values ​​and the historical coefficients; a linear regression equation is established based on each historical parameter value and each historical coefficient to obtain a calculation formula; the current parameter value is input into the calculation formula to obtain the indicator coefficient corresponding to the indicator-related parameter, wherein an influence relationship exists between the input current parameter value and the indicator coefficient corresponding to the indicator-related parameter.

[0050] In one embodiment of the present application, if the playback-related index is a volume index, the playback index value corresponding to the volume index is calculated by the following method: obtaining vehicle operation data and driving environment data of the target vehicle, the vehicle operation data including the driving speed, and the driving environment data including the road speed limit information, noise information and light intensity information; determining the motion state of the target vehicle according to the driving speed, if the motion state of the target vehicle is moving, comparing the driving speed with the road speed limit information, if the driving speed is greater than the road speed limit information, determining that the target vehicle is speeding, calculating the speeding ratio based on the driving speed and the road speed limit information, determining the speeding increment coefficient corresponding to the speeding ratio from the preset speeding coefficient according to the matching result between the speeding ratio and the preset ratio range, and In the embodiment, the volume index is positively correlated with the overspeed increment coefficient; according to the matching result between the noise information and the preset noise range, the target noise coefficient corresponding to the noise information is determined from the preset noise coefficient, wherein the volume index is positively correlated with the target noise coefficient; based on the matching result between the light intensity information and the preset light range, the target light coefficient corresponding to the light intensity information is determined from the preset light coefficient, wherein the volume index is negatively correlated with the target light coefficient; a weighted sum calculation is performed according to the weights corresponding to the overspeed increment coefficient, the target noise coefficient, the target light coefficient and each parameter coefficient to obtain a playback index value corresponding to the volume index, wherein the parameter coefficient includes at least one of the overspeed increment coefficient, the target noise coefficient and the target light coefficient. Among them, the preset speeding coefficient is the speeding coefficient corresponding to each preset ratio range, for example, when the preset ratio range is less than 10%, the corresponding preset speeding coefficient is 0.2; the preset noise coefficient is the noise coefficient corresponding to each preset noise range, for example, when the preset noise range is 0-40, the corresponding preset noise coefficient is 0, when the preset noise range is 40-70, the corresponding preset noise coefficient is 0.5, and when the preset noise coefficient is 70-100, the corresponding preset noise coefficient is 1; the preset light coefficient is the light coefficient corresponding to each preset illumination range, for example, when the preset illumination range is 8-10, the corresponding preset light coefficient is 0, when the preset illumination range is 0-5, the corresponding preset light coefficient is 1, and when the preset illumination range is 5-8, the corresponding preset light coefficient is 0.5. It should be noted that the preset ratio range, preset speeding coefficient, preset noise range, preset noise coefficient, preset illumination range and preset light coefficient in this embodiment are only for example description and can be adjusted according to needs. This application does not limit this and should not bring any limitation to the functions and scope of use of the embodiments of the present invention.

[0051] In this embodiment, the data provided by the speed sensor, i.e., the driving speed, is used to determine whether the target vehicle is stationary; if the target vehicle is stationary, the speeding increment coefficient corresponding to the driving speed is not determined. If the target vehicle is in motion, it is determined whether the target vehicle is speeding, wherein whether the speeding can be determined according to the speed limit of the road, and the system can also actively set the speed limit size. For example, if the road speed limit information is 120km / h, the target vehicle is traveling at a speed of 130km / h, then the target vehicle is determined to be speeding, and the speeding ratio is calculated according to the driving speed and the road speed limit information: speeding ratio = (130km / h-120km / h) / 120km / h×100%, the speeding ratio is approximately equal to 8.33%, and the speeding increment coefficient corresponding to the speeding ratio is determined by looking up the speeding table (the speeding table can be set and changed by itself), for example, when the speeding ratio is less than 10%, the speeding increment coefficient is equal to 0.2, and the frequency is increased by 10%. It should be noted that this embodiment is only for example description, and should not bring any restrictions to the functions and scope of use of the embodiments of the present invention.

[0052] In this embodiment, the data uploaded by the environmental noise sensor, i.e., the noise information, is used to determine whether the noise information exceeds the noise threshold range. If the noise information is greater than the maximum value of the noise threshold range, the noise information is adjusted to the maximum value of the noise threshold range; if the noise information is less than the minimum value of the noise threshold range, the noise information is adjusted to the minimum value of the noise threshold range. Among them, the noise threshold ranges of different manufacturers are different, and the noise threshold range is determined by the sensor. The levels can be divided according to the noise threshold range. For example, the noise threshold range of a certain manufacturer is set to 0-100, where 0-40 is a noise-free environment, 40-70 is a weak noise environment, and 70-100 is a strong noise environment. By looking up the noise table, the noise coefficient corresponding to each noise environment is found, such as the noise coefficient of the noise-free environment is 0; the noise coefficient of the weak noise environment is 0.5, and the noise coefficient of the strong noise environment is 1, wherein the noise table can be modified. It should be noted that this embodiment is only for example and should not bring any limitation to the function and scope of use of the embodiment of the present invention.

[0053] In this embodiment, the data uploaded by the light sensor, i.e., the light intensity information, is used to determine whether the light intensity information exceeds the light intensity threshold range. If the light intensity information exceeds the maximum value of the light intensity threshold range, the light intensity information is adjusted to the maximum value of the light intensity threshold range; if the light intensity information is less than the minimum value of the light intensity threshold range, the light intensity information is adjusted to the minimum value of the light intensity threshold range. Among them, the light intensity threshold ranges of different manufacturers are different. The light intensity threshold range is determined by the sensor. The levels can be divided according to the range to determine whether it is in a dark environment. For example, the light intensity threshold range of a certain manufacturer is set to 0-10. When the light is sufficient, the output signal, i.e., the light intensity information, is higher than a certain threshold such as 8. The system will consider the environment to be bright and the light coefficient is set to 0; conversely, when the output signal is lower than another threshold such as 5, the system will determine that the environment is dark and the light coefficient is set to 1. When the output signal is between 5-8, it is considered to be relatively dark and the light coefficient is set to 0.5. It should be noted that this embodiment is only for illustrative purposes and should not bring any limitations to the functions and scope of use of the embodiments of the present invention.

[0054] In this embodiment, the playback index value corresponding to the volume index is calculated by calculating each parameter coefficient and the weight corresponding to each parameter coefficient. The parameter coefficient may include a target timbre coefficient, an overspeed increment coefficient, a target noise coefficient, and a target light coefficient. Each parameter coefficient is multiplied by a corresponding preset weight (assuming that the corresponding weights are 1:2:3:2, respectively) to obtain the coefficient of volume increase or decrease, that is, the playback index value corresponding to the volume index, as well as the channel and playback frequency. Among them, the preset weight can be adjusted according to user preferences.

[0055] In this embodiment, the third thread opened by the perception module is used to collect the target timbre coefficient, overspeed increment coefficient, target noise coefficient and target light coefficient in real time, and is used to adjust the chime's baseline value, that is, the playback index value corresponding to the volume index, as well as the triggered playback timing, playback frequency, etc. In addition, an operating threshold range of the chime baseline value is set. If the chime baseline value is greater than the maximum value of the operating threshold range, the chime baseline value is adjusted to the maximum value of the operating threshold range; if the chime baseline value is less than the minimum value of the operating threshold range, the chime baseline value is adjusted to the minimum value of the operating threshold range. For example, the operating threshold range is set to 0-10. When the chime baseline value is greater than 10, it is set to 10. When the chime baseline value is less than 0, it is set to 0. Taking formula (1) as an example, the calculation method of the target volume coefficient is explained:

[0056] chime 新基准值 =chime 原基准值 +chime 目标音色系数 ×1+chime 超速增量系数 ×2

[0057] +chime 目标噪声系数 ×3+chime 目标光线系数 ×2 formula (1)

[0058] Among them, chime 新基准值 is the new baseline value, chime 原基准值 is the original reference value, i.e. the reference value calculated last time, chime 目标音色系数 is the target timbre coefficient, chime 超速增量系数 is the speed increment coefficient, chime 目标噪声系数 is the target noise coefficient, chime 目标光线系数 is the target light coefficient.

[0059] In this embodiment, the playback index value corresponding to the volume index is calculated by calculating each parameter coefficient and the weight corresponding to each parameter coefficient, and the playback index value corresponding to the volume index is adjusted by each parameter coefficient and the weight corresponding to each parameter coefficient. 原基准值 That is, the initial playback index value corresponding to the volume index, expressed in chime 原基准值 is 6, chime 目标音色系数 is 0.5, chime 超速增量系数 is 0.2, chime 目标噪声系数 is 1, chime 目标光线系数 Taking 0.5 as an example, chime is calculated according to formula (1): 新基准值 That is, the playback index value corresponding to the volume index is 10.9, and since the chime reference value ranges from 0 to 10, the playback index value corresponding to the final volume index is 10. It should be noted that this embodiment is only for illustrative purposes and should not bring any limitation to the functions and scope of use of the embodiments of the present invention.

[0060] In this embodiment, after obtaining the playback index value corresponding to the volume index, it is determined whether the volume, i.e., the playback index value corresponding to the volume index, exceeds the volume threshold range. If the volume is greater than the maximum value of the volume threshold range, the volume is set to the maximum value of the volume threshold range; if the volume is less than the minimum value of the volume threshold range, the volume is set to the minimum value of the volume threshold range. For example, the volume threshold range is set to 0-10. If the volume exceeds the maximum volume value of 10, the volume is set to the maximum volume value of 10. If the calculated value is lower than the minimum volume value of 0, the volume is set to the minimum volume value of 0.

[0061] In one embodiment of the present application, if the playback-related indicator is a channel indicator, the playback index value corresponding to the channel indicator is determined by the following method: obtaining direction information and multiple channels corresponding to each direction; determining the preset channel coefficients corresponding to each channel according to the influence relationship; determining the target channel coefficient corresponding to the direction information from each preset channel coefficient according to the matching result between the direction information and each channel, wherein the channel indicator and the target channel coefficient are positively correlated; and using the target channel coefficient as the playback index value corresponding to the channel indicator.

[0062] In this embodiment, the direction is determined by the data provided by the direction sensor, that is, the direction information, and the channel coefficient is determined according to the direction. For example, the channel corresponding to the left direction is the left channel, and the channel corresponding to the right direction is the right channel, wherein the channel coefficient of the left channel is set to 1, and the channel coefficient of the right channel is set to 2. It should be noted that the examples in this embodiment are only for illustrative purposes to more clearly explain the determination of the playback index value corresponding to the channel index, and should not bring any limitation to the function and scope of use of the embodiments of the present invention.

[0063] In one embodiment of the present application, if the playback-related index is a timbre index, the playback index value corresponding to the timbre index is determined by the following method: the sound source type of the sound data to be played is obtained; the target timbre coefficient is obtained based on the sound source type, wherein, if the sound source type is an alarm type, the target timbre coefficient is an alarm coefficient, and if the sound source type is a prompt type, the target timbre coefficient is a prompt coefficient; the target timbre coefficient is used as the playback index value corresponding to the timbre index. Among them, the alarm coefficient can be 1, and the prompt coefficient can be 0.5. It should be noted that the alarm coefficient and the prompt coefficient in this embodiment are only for example and can be adjusted according to needs. This application does not limit this, and should not bring any limitations to the functions and scope of use of the embodiments of the present invention.

[0064] In this embodiment, the sound source type is determined. If the sound source type is an alarm type, it is determined whether the user has customized the timbre of the alarm type sound data. If so, the alarm coefficient is adjusted according to the timbre of the user-defined alarm type sound data, and the adjusted alarm coefficient is used as the target timbre coefficient. If the sound source type is a prompt type, it is determined whether the user has customized the timbre of the prompt type sound data. If so, the prompt coefficient is adjusted according to the timbre of the user-defined prompt type sound data, and the adjusted prompt coefficient is used as the target timbre coefficient.

[0065] In one embodiment of the present application, if the playback-related indicators are playback timing and playback frequency, the playback indicator value corresponding to the playback timing and the playback indicator value corresponding to the playback frequency are determined by the following method: matching the overspeed ratio with the preset ratio; determining the playback frequency from the preset frequency change according to the matching result, and determining the playback timing from the preset timing change according to the matching result; using the playback frequency as the playback indicator value corresponding to the playback frequency, and using the playback timing as the playback indicator value corresponding to the playback timing. Among them, the preset frequency change is the frequency change corresponding to the preset ratio, and the preset timing change is the timing change corresponding to the preset ratio.

[0066] In this embodiment, the initial playback frequency and initial playback timing are obtained, and the overspeed ratio is matched with the preset ratio; the playback frequency change is determined from the preset frequency change according to the matching result, and the playback frequency is determined according to the initial playback frequency and the playback frequency change; the playback timing change is determined from the preset timing change according to the matching result, and the playback timing is determined according to the initial playback timing and the playback timing change. The playback timing and playback frequency corresponding to the overspeed ratio are determined by looking up the overspeed table. For example, when the overspeed ratio is less than 10%, the playback timing is advanced by 1 second and the frequency is increased by 10%. It should be noted that this embodiment is only for illustration and should not bring any limitations to the functions and scope of use of the embodiments of the present invention.

[0067] In step S240, the target vehicle is controlled to adjust and play the sound data to be played according to the playback index value.

[0068] In one embodiment of the present application, the target vehicle is controlled to adjust the sound data to be played according to the playback index value corresponding to the playback-related index, and the sound data to be played is played according to the adjustment result.

[0069] In this embodiment, the volume of the sound data to be played is adjusted according to the playback index value corresponding to the volume index, the channel of the sound data to be played is adjusted according to the playback index value corresponding to the channel index, the timbre of the sound data to be played is adjusted according to the playback index value corresponding to the timbre index, the playback timing of the sound data to be played is adjusted according to the playback index value corresponding to the playback timing, the playback frequency of the sound data to be played is adjusted according to the playback index value corresponding to the playback frequency, and the sound data to be played is played according to the adjustment result.

[0070] In one embodiment of the present application, the current scene is obtained, the playback index value corresponding to the current scene and each playback-related index is matched, and each playback index value is saved in a parameter set corresponding to the current scene; the number of playback index values ​​in the parameter set corresponding to the current scene is counted; if the number of playback index values ​​is greater than a preset number, the playback index values ​​are averaged to obtain the average value, and the average value is determined as a new playback index value; if the usage scenario is the current scene, the sound data to be played is adjusted according to the new playback index value.

[0071] In this embodiment, assuming that the preset number is set to 1000, if the usage scenario is the current scenario, and the number of playback index values ​​is less than or equal to 1000, the playback index value is used to adjust the sound data to be played. If the usage scenario is the current scenario, and the number of playback index values ​​is greater than 1000, the average value of the 1000 playback index values ​​saved most recently is calculated to obtain a new playback index value, and the sound data to be played is adjusted according to the new playback index value. This prevents the failure of the sensor to obtain the corresponding data in real time, thereby preventing the failure to adjust the sound data to be played.

[0074] This application determines the coefficient of the current parameter value through the influence relationship, obtains the index coefficient corresponding to the index-related parameter, and calculates according to the index coefficient to obtain the playback index value corresponding to the playback-related index. According to the playback index value, the target vehicle is controlled to adjust and play the sound data to be played, and the sound is automatically adjusted. There is no need for the driver to distract his attention to find and operate the physical button, which can reduce the driver's distraction risk and improve driving safety. This application uses the vehicle's sensor data (such as speed, noise, light intensity, etc.), and the vehicle can perceive the driving environment in real time, and automatically adjust the volume, timbre, playback timing and playback frequency of the prompt sound accordingly, ensuring that the best prompt effect can be achieved in any situation. It can not only enhance the timeliness of the vehicle's broadcast of various important information, but also improve the overall quality of the car interior, creating a more advanced and humane driving environment.
