[0030] To better understand the technical solution of the present application, the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0032] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "the" and "said" used in the embodiments of the present application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0033] It should be understood that the term " / or" used herein is only a relational term describing associated objects, indicating that three relationships may exist. For example, a / or b may represent: a exists alone, a and b exist simultaneously, and b exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0034] During the operation of a new energy vehicle, when using electricity as the power source or driving at a low speed, due to the too low noise, road users (such as pedestrians, non-motor vehicle drivers, etc.) may not be able to perceive the approach of the vehicle.

[0035] Currently, a pedestrian warning sound can be output to warn road users, so that road users can perceive the approach of the vehicle in advance. To improve the warning effect of the pedestrian warning sound, according to the preset sound effect data, the output of the pedestrian warning sound at different vehicle speeds can be controlled.

[0036] For ease of understanding, refer to Figure 1 , which is a schematic structural diagram of a vehicle provided by an embodiment of the present application. As Figure 1 shown, the vehicle 100 includes a controller 101. The controller 101 can be used to store and process relevant data, and output a pedestrian warning sound according to the processed data.

[0037] However, when the sound effect data needs to be updated, the storage addresses of the sound effect data may be relatively scattered, which is not conducive to management and update. In addition, it may be necessary to rewrite the code, affecting the update efficiency.

[0038] In view of the above problems, in the embodiments of the present application, first, according to the target storage address, obtain the sound effect data design table; then, according to the current vehicle speed and the sound effect data design table, determine the target audio and / or target volume corresponding to the current vehicle speed; finally, control the output of the sound source data according to the target audio and / or target volume corresponding to the current vehicle speed. In other words, a sound effect data storage address (i.e., the target storage address) can be planned for the sound effect data, which is convenient for the management and update of the sound effect data. Since the sound effect data is stored in the target storage address, when the sound effect data needs to be updated, the sound effect data in the target storage address can be changed without rewriting the code, improving the update efficiency.

[0039] Specifically, it will be described in detail below in combination with the accompanying drawings and specific embodiments.

[0040] See Figure 2 , which is a schematic flowchart of a method for controlling a pedestrian warning sound provided by an embodiment of the present application. This method can be applied to Figure 1 the application scenario shown, and specifically includes the following steps.

[0041] Step S201: Obtain the sound effect data design table according to the target storage address.

[0042] In the embodiments of the present application, the sound effect data design table includes the mapping relationship between the vehicle speed and the audio and / or volume.

[0043] It can be understood that each vehicle speed may correspond to an audio. Exemplarily, the audio corresponding to the vehicle speed V1 is f1; the audio corresponding to the vehicle speed V2 is f2; the audio corresponding to the vehicle speed V3 is f3; and so on. This is not elaborated in the embodiments of the present application.

[0044] Each vehicle speed may correspond to a volume. Exemplarily, the volume corresponding to the vehicle speed V1 is v1; the volume corresponding to the vehicle speed V2 is v2; the volume corresponding to the vehicle speed V3 is v3; and so on. This is not elaborated in the embodiments of the present application.

[0045] In a possible implementation manner, the sound effect data design table further includes sound source data. It can be understood that the sound source data can be stored in the target storage address and stored in the sound effect data design table together with the audio and / or volume, which is more convenient for centralized management and update of the sound source data. When the sound source data needs to be updated, the sound source data in the target storage address can be changed without rewriting the code, improving the update efficiency of the sound source data.

[0046] For the convenience of description, the sound effect data represents the sound source data, the audio, and the volume.

[0047] In a possible implementation manner, the target storage address is a storage address in the flash.

[0048] It is understandable that storage addresses are planned for the sound effect data in the flash, that is, the target storage addresses, which is conducive to centralized management and update. The sound effect data design table fixes the storage addresses of the sound effect data in the flash. When the sound effect data needs to be updated, after changing the sound effect data in the corresponding storage address of the sound effect data design table, the sound effect data in the corresponding address of the flash will also be changed and saved, without the need to rewrite the code, improving the update efficiency.

[0049] In addition, storing the sound effect data in the flash can store the sound effect data for a long time and is not easily lost. Step S201: Determine the target audio and / or target volume corresponding to the current vehicle speed according to the current vehicle speed and the sound effect data design table.

[0050] In the embodiment of the present application, the target audio and / or target volume corresponding to the current vehicle speed can be obtained at the address corresponding to the sound effect data design table.

[0051] It should be noted that the sound source data can also be obtained at the address corresponding to the sound effect data design table.

[0052] Step S203: Control the sound source data to output according to the target audio and / or target volume.

[0053] In the embodiment of the present application, after obtaining the sound effect data at the target storage address, the sound source data in the sound effect data can be controlled to output a pedestrian warning sound according to the audio and / or volume in the sound effect data (i.e., the target audio and / or target volume) to warn pedestrians.

[0054] In practical applications, the storage capacity of the sound source data may be large, and it is impossible to take both storage space and sound source quality into account.

[0055] See Figure 3 , which is another control method for the pedestrian warning sound provided by the embodiment of the present application. As Figure 3 shown, on the basis of the embodiment shown in Figure 2 , step S203 specifically includes the following steps.

[0056] Step S2031: Process the sound source data using an oversampling algorithm to obtain the processed sound source data.

[0057] In the embodiment of the present application, the oversampling algorithm can increase the sampling frequency of the sound source data. Specifically, in a possible implementation manner, the average value of the first sampling point and the second sampling point can be inserted between the first sampling point and the second sampling point, and the first sampling point and the second sampling point are any two adjacent sampling points.

[0058] It is understandable that the oversampling algorithm improves the sampling frequency of the sound source data by inserting the average value between adjacent sampling points. A high sampling frequency of the sound source data means that more sampling data of the obtained sound source data is sampled per unit time.

[0059] Exemplarily, refer to Figure 4 , which is a schematic diagram of a kind of sound source data provided by an embodiment of the present application. As Figure 4 shown in (1) of Figure 4 is the original waveform of the sound source data, Figure 4 shown in (2) of

[0060] is the waveform of the sound source data output before increasing the sampling frequency, Figure 4 shown in (3) of Figure 4 is the waveform of the sound source data output after doubling the sampling frequency. Figure 4 It is understandable that the sound source data shown in (1) of

[0061] is sampled. As shown in (2) of

[0062] before increasing the sampling frequency, the original waveform of the sound source data is sampled 10 times per unit time; as shown in (3) of

[0063] after doubling the sampling frequency, the original waveform of the sound source data is sampled 20 times per unit time. That is to say, before increasing the sampling frequency, if you want to sample the original waveform of the sound source data 20 times, more sound source data is required, increasing the storage amount of the sound source data.

[0064] In some application scenarios, users may expect to update the sound effect data. For example, when it is necessary to update or upgrade the pedestrian warning software in different vehicle models, the sound effect data needs to be updated again.

[0065] In an embodiment of the present application, a storage address for the sound effect data (i.e., the target storage address) can be planned for the sound effect data. The upper computer edits the sound effect data design table, and generates a corresponding sound effect data file package (for example, hev file package, etc.) according to the edited sound effect data design table, and then burns the sound effect data file package to the target storage address in the flash.

[0066] When it is necessary to update the sound effect data, by editing the sound effect data in the sound effect data design table, the sound effect data corresponding to the target storage address in the flash can be updated without rewriting the code, realizing the software architecture of pedestrian warning in different vehicle models and saving the development cost at the same time.

[0067] Based on the Figure 2 embodiment shown, it further includes: receiving the update information of the sound effect data design table and updating the sound effect data design table stored at the target storage address.

[0068] For the sake of easy understanding, it will be described in detail in the text in combination with the attached drawings. Refer to Figure 5 , which is a schematic diagram of an application scenario provided by an embodiment of the present application. As Figure 5 described, the host computer 300 and the controller 101 are communicatively connected. The host computer 300 can be used to send the update information of the received sound effect data design table to the controller 101. The controller 101 can be used to receive the update information of the sound effect data design table. When receiving the update information of the sound effect data design table sent by the host computer 300, the sound effect data is refreshed.

[0069] In addition, the host computer 300 can display the interface for adjusting the sound effect data and adjust the sound effect data. Refer to Figure 6 , which is a schematic diagram of the interface of a host computer provided by an embodiment of the present application. As Figure 6 shown, the display interface 400 of the host computer includes but is not limited to a sound source mode selection area 401, an audio selection area 402, and a volume selection area 403. The sound source mode selection area 401 can be used to adjust the sound source mode; the audio selection area 402 can be used to adjust the audio at different vehicle speeds; the volume selection area 403 can be used to adjust the volume at different vehicle speeds.

[0070] Specifically, below will be combined with Figures 7 to 9B , to introduce the changes in the display interface of the host computer when adjusting the sound source, audio, and volume.

[0071] Refer to Figure 7 , which is a schematic diagram of the change of the sound source provided by an embodiment of the present application. As Figure 7 shown in (1) of , the sound source mode selection area 401 includes a sound source mode setting item 4011. The sound source mode setting item 4011 includes a sound source mode selection control 4012 and an information item 4013. When the user clicks the sound source mode selection control 4012, the sound source mode selection area 401 can display a sound source mode sub-area 4014. The information item 4013 can be used to display the current sound source mode. For example, the current sound source mode is the first sound source.

[0072] After clicking the sound source mode selection control 4012, as Figure 7As shown in (2) of [reference], the sound source mode sub-region 4014 includes, but is not limited to, a first sound source, a second sound source, a third sound source, and a fourth sound source. Additionally, a sliding button 4015 is included on the right side of the sound source mode sub-region 4014. The user can view or select other sound sources by dragging the sliding button 4015 up and down. Exemplarily, when the sliding button 4015 is dragged downward, as Figure 7 shown in (3) of [reference], the sound source mode sub-region 4014 displays a fifth sound source, a sixth sound source, a seventh sound source, and an eighth sound source.

[0073] In the sound source mode sub-region 4014, different sound source modes can be selected. Exemplarily, after clicking on the seventh sound source in the sound source mode sub-region 4014, as Figure 7 shown in (4) of [reference], the information item 4013 displays the seventh sound source. Refer to Figure 8 , which is a schematic diagram of an audio change provided by an embodiment of the present application. As Figure 8 shown in (1) of [reference], the audio selection region 402 includes an audio selection switch setting item 4021 and an audio setting item 4022.

[0074] The audio selection switch setting item 4021 can be used to turn on or off the audio selection region 402. As Figure 8 shown in (1) of [reference], the audio selection switch setting item 4021 is in the off state, and clicking on this audio selection switch setting item 4021 can switch it to the on state. As Figure 8 shown in (2) of [reference], the audio selection switch setting item 4021 is in the on state. After the audio selection switch setting item 4021 is in the on state, the audio can be set through the audio setting item 4022.

[0075] As Figure 8 shown in (2) of [reference], the audio setting item 4022 usually includes multiple audio setting boxes corresponding to different vehicle speeds. For example, the first vehicle speed corresponds to the first audio setting box 4023; the second vehicle speed corresponds to the second audio setting box 4024; the third vehicle speed corresponds to the first audio setting box 4025; and so on. This is not elaborated further in the embodiments of the present application.

[0076] The audio setting item 4022 can set the audio at different vehicle speeds. For example, when setting the audio at the first vehicle speed, the first audio setting box 4023 corresponding to the first vehicle speed can be clicked, and 'f' can be entered in the first audio setting box 4023. As Figure 8 shown in (3) of [reference], after 'f' is entered in the first audio setting box 4023, the information in the first audio setting box corresponding to the first vehicle speed is 'f', which is the audio corresponding to the first vehicle speed.

[0077] It should be noted that when the information in the audio setting box corresponding to the vehicle speed is "n.a.", it means that no information is entered in the text box. In addition, the audio setting box described in the above embodiments is only an exemplary illustration, and the audio setting item 4022 also includes audio setting boxes corresponding to other vehicle speeds. For example, the fourth vehicle speed corresponds to the fourth audio setting box, the fifth vehicle speed corresponds to the fifth audio setting box, and so on.

[0078] See Figure 9A , which is a schematic diagram of the volume change provided by the embodiment of the present application. As Figure 9A shown in (1) of

[0079] , the volume selection area 403 includes a volume selection switch setting item 4031 and a volume setting item 4032. Figure 9A As shown in (1) of Figure 9A , the volume selection switch setting item 4031 is in the off state. Clicking on the volume selection switch setting item 4031 can switch it to the on state. As

[0080] shown in (2) of Figure 9A , the volume selection switch setting item 4031 is in the on state. After the volume selection switch setting item 4031, the volume setting item 4032 can be set.

[0081] It should be noted that when the information in the volume setting box corresponding to the vehicle speed is "n.a.", it means that no information is entered in the text box. In addition, the volume setting box and the volume slider described in the above embodiments are only exemplary illustrations, and the audio setting item 4022 also includes volume setting boxes and volume sliders corresponding to other vehicle speeds. For example, the fourth vehicle speed corresponds to the fourth volume setting box and the fourth volume slider, the fifth vehicle speed corresponds to the fifth volume setting box and the fifth volume slider, and so on.

[0082] That is to say, it can be set in two ways: the volume setting box and the volume slider. Specifically, as Figure 9A shown in (2) of Figure 9AAs shown in (3) therein, after inputting f in the first volume setting box 4033, the information in the first volume setting box corresponding to the first vehicle speed is v, that is, the volume corresponding to the first vehicle speed.

[0083] When setting the volume at different vehicle speeds through the volume slider, the sliding button on the volume slider can be slid in both directions of the volume slider. When the sliding button slides to the left along the volume slider, the volume decreases; when the sliding button slides to the right along the volume slider, the volume increases.

[0084] See Figure 9B , which is another schematic diagram of volume change provided by the embodiment of the present application. As Figure 9B shown in (1) therein, when increasing the volume at the first vehicle speed, the first sliding button 4039 on the first volume slider 4034 can be dragged to slide along the arrow direction. As shown in (2) in FIG. 9, the position after the first sliding button 4039 is the volume corresponding to the first vehicle speed.

[0085] It should be noted that the above embodiments are only exemplary descriptions. In the embodiments of the present application, some or all of the sound source, audio, and volume can be adjusted simultaneously, and the embodiments of the present application do not make specific limitations on this.

[0086] In addition, in the embodiments of the present application, the audio at different vehicle speeds can also be set through the audio slider. The specific implementation method is similar to the embodiment of setting the volume through the volume slider described above. For the sake of brevity of description, the embodiments of the present application will not elaborate on this anymore.

[0087] As described above, after adjusting the sound effect data at different vehicle speeds through the host computer, the sound effect data design table can be updated, and a corresponding sound effect data file package (for example, hev file package, etc.) can be generated according to the updated sound effect data design table, and then the sound effect data file package is burned into the target storage address in the flash.

[0088] It should be noted that some or all of the sound effect data can be stored in the target storage address. The above embodiments are only exemplary descriptions, and the embodiments of the present application do not make specific limitations on this.

[0089] In the embodiments of the present application, a sound effect data storage address (i.e., the target storage address) can be planned for the sound effect data, which is convenient for the management and update of the sound effect data. Since the sound effect data is stored in the target storage address, when the sound effect data needs to be updated, the sound effect data in the target storage address can be changed, and there is no need to rewrite the code, which improves the update efficiency.

[0090] Corresponding to the above method embodiments, the present application also provides a control device for pedestrian warning sounds. See Figure 10, which is a schematic structural diagram of a control device for pedestrian warning sounds provided by an embodiment of the present application. As Figure 10 shown, the control device 500 for pedestrian warning sounds includes: a sound effect data design table acquisition module 501, a target audio and / or target volume determination module 502, and a control sound source data output module 503. Specifically, the sound effect data design table acquisition module 501 is configured to acquire a sound effect data design table according to a target storage address, and the sound effect data design table includes a mapping relationship between vehicle speed and audio and / or volume; the target audio and / or target volume determination module 502 is configured to determine a target audio and / or target volume corresponding to the current vehicle speed according to the current vehicle speed and the sound effect data design table; the control sound source data output module 503 is configured to control the sound source data to be output according to the target audio and / or the target volume.

[0094] Corresponding to the above embodiment, the embodiment of the present application further provides a computer-readable storage medium, wherein the computer-readable storage medium may store a program, and when the program runs, it can control the device where the computer-readable storage medium is located to execute some or all of the steps in the above method embodiment. Specifically, the computer-readable storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM for short), or a random access memory (RAM for short), etc.

[0095] Corresponding to the above embodiment, the embodiment of the present application further provides a computer program product, which includes executable instructions. When the executable instructions are executed on a computer, the computer is caused to execute some or all of the steps in the above method embodiment.

[0096] In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "And / or" describes the association relationship of associated objects and indicates that there can be three relationships. For example, A and / or B can represent the cases of A existing alone, A and B existing simultaneously, and B existing alone. Where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects before and after. "At least one of the following" and its similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, and c can represent: a, b, c, a - b, a - c, b - c, or a - b - c, where a, b, and c can be single or multiple.
