[0053] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0054] Refer to Figure 1 , Figure 1Schematic diagram of the structure of a flat tire assistance recognition device for the hardware operating environment involved in the solution of the embodiment of the present invention.

[0055] As shown in Figure 1 , the electronic device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display) and an input unit such as a keyboard (Keyboard). Optionally, the user interface 1003 may further include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. Optionally, the memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0056] Those skilled in the art can understand that Figure 1 the structure shown in

[0057] does not constitute a limitation on the electronic device, and may include more or fewer components than shown in the figure, or combine certain components, or have different component arrangements. Figure 1 As shown in

[0058] In Figure 1 the electronic device shown, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the electronic device of the present invention may be provided in the flat tire assistance recognition device. The electronic device calls the flat tire assistance recognition program stored in the memory 1005 through the processor 1001 and executes the flat tire assistance recognition method provided by the embodiment of the present invention.

[0059] The embodiment of the present invention provides a flat tire assistance recognition method. Referring to Figure 2 , Figure 2 is a schematic flowchart of the first embodiment of a flat tire assistance recognition method of the present invention.

[0060] In this embodiment, the flat tire assistance recognition method includes the following steps:

[0061] Step S10: When the flat tire auxiliary recognition function is turned on, collect ambient sound data through the vehicle-mounted microphone.

[0062] It should be noted that the execution subject of this embodiment can be the flat tire auxiliary recognition device or the vehicle itself. The flat tire auxiliary recognition device can be the main controller in the vehicle or a sub-controller that can control components such as the vehicle-mounted microphone and vehicle-mounted audio installed in the vehicle. This embodiment does not limit this. In this embodiment and the following embodiments, the flat tire auxiliary recognition method of the present invention will be described by taking the flat tire auxiliary recognition device as an example.

[0063] It should be noted that if the flat tire auxiliary recognition function is turned on, it means that the driver hopes that the vehicle can assist the driver in making a flat tire determination through the flat tire auxiliary recognition function to avoid misjudgment or missed judgment of the vehicle flat tire phenomenon. Therefore, at this time, the ambient sound can be collected through the vehicle-mounted microphone to obtain ambient sound data. Among them, in order to ensure that the collected ambient sound data is closer to the ambient sound data actually heard by the driver, when collecting the ambient sound, a vehicle-mounted microphone closer to the driver can be used. For example: collect the ambient sound through the vehicle-mounted microphone installed at the headrest of the driver's seat of the vehicle.

[0064] In actual use, in order to facilitate the driver to clearly know whether the flat tire auxiliary recognition function is turned on, a corresponding auxiliary flat tire icon can be set on the vehicle dashboard. If the flat tire auxiliary recognition function is turned on, the auxiliary flat tire icon will be lit.

[0065] In a specific implementation, since the closing of the window or the playing of entertainment sounds (such as music or video sounds) by the vehicle-mounted multimedia will cause the volume of the ambient sound that can be collected to be too low, in order to ensure that the ambient sound heard by the driver is clearer as much as possible, step S10 of this embodiment may include:

[0066] When the auxiliary recognition function is turned on, control the vehicle window to open and / or reduce the volume of the vehicle-mounted multimedia;

[0067] Collect ambient sound data through the vehicle-mounted microphone.

[0068] It should be noted that controlling the vehicle window to open can be to control the vehicle window to open to a preset opening amplitude, and reducing the volume of the vehicle-mounted multimedia can be to reduce the volume of the vehicle-mounted multimedia to a preset volume. Among them, the preset opening amplitude and preset volume data can both be pre-set by the administrator of the flat tire auxiliary recognition device according to actual needs. For example: set the preset opening amplitude to 30%, and set the preset volume data to any value in the range of 0-10%.

[0069] It can be understood that opening the window can make the collected ambient sound clearer, enabling the driver to more accurately judge whether there is a flat tire; while reducing the volume of the in-vehicle multimedia can reduce the interference of the entertainment sound played by the multimedia on the ambient sound, making the ambient sound more obvious, so as to facilitate the driver to judge whether there is a flat tire.

[0070] Step S20: Perform high-frequency filtering on the ambient sound data to obtain filtered audio data.

[0071] It should be noted that performing high-frequency filtering on the ambient sound data to obtain filtered audio data can be to filter the high-frequency sound data in the collected ambient sound data and use the filtered ambient sound data as the filtered audio data. Among them, the high-frequency sound data can be sound data with relatively high frequencies such as human voices, songs, and whistles.

[0072] In a specific implementation, performing high-frequency filtering on the ambient sound data to obtain filtered audio data can be to clear or weaken the part of the ambient sound data with a frequency higher than a preset frequency threshold through an audio filter, and use the remaining part as the filtered audio data. Among them, the preset frequency threshold can be set in advance by the administrator of the flat tire assistance recognition device according to actual needs.

[0073] Of course, when performing high-frequency filtering, a deep learning algorithm or a neural network model can also be used to construct a high-frequency filtering model, and the high-frequency filtering of the ambient sound data can be realized through the trained high-frequency filtering model. This embodiment does not limit this.

[0074] Step S30: Play the filtered audio data through the in-vehicle audio to assist the vehicle driver in flat tire recognition.

[0075] It should be noted that the filtered audio data is used to form an enhanced sound effect with the ambient sound transmitted to the vehicle driver's ears. Playing the filtered audio data through the in-vehicle audio will generate sound waves in the same direction as the ambient sound. Based on the principle of sound frequency resonance, the sound played by the in-vehicle audio can be superimposed on the ambient sound, thereby partially enhancing the ambient sound. And since the filtered audio data is sound data that has undergone high-frequency filtering and has removed high-frequency sounds such as human voices, songs, and whistles, when enhancing the ambient sound, only the low-frequency ambient sound will be enhanced, enabling the driver to more easily identify sounds such as rattling caused by a flat tire of the vehicle, thereby improving the accuracy of flat tire recognition.

[0076] For the sake of easy understanding, now in combination with Figure 3 、 4 and 5 for description, but this solution is not limited. Figure 3 is the schematic diagram of ambient sound enhancement for this embodiment. As shown in Figure 3As shown, for the ambient sound collected by the microphone, assuming its sound intensity is 1, and the sound intensity of the enhanced sound generated by playing the filtered audio data through the in-vehicle audio is 0.5. After the sound is in the same frequency resonance, the sound intensity of the sound actually heard by the driver is 1.5.

[0077] Figure 4 It is a schematic diagram for explaining the sound delay. As Figure 4 shown, since the microphone collects the ambient sound data (with an intensity of 1.0), after processing, and then played by the in-vehicle audio, the output enhanced sound (with an intensity of 0.5) will have a certain small delay (in milliseconds). However, in actual situations, the small delay of the enhanced sound output by the in-vehicle audio will only slightly reduce the enhancement effect of the low-frequency ambient sound. The sound intensity of the ambient sound finally heard by the driver will still be greater than the original ambient sound, but will be lower than 1.5. Among them, in order to ensure the ambient sound enhancement effect as much as possible, the in-vehicle microphone and the in-vehicle audio can be set near the driver's ear.

[0078] Figure 5 It is a schematic diagram for high-frequency sound filtering. As Figure 5 shown, the ambient sound collected by the microphone contains a large amount of high-frequency sounds. After high-frequency processing, the high-frequency sounds among them will be filtered (removed or weakened). Then, the enhanced sound finally output by the audio will only enhance a part of the ambient sound. Finally, it is ensured that only a part of the ambient sound data heard by the driver is enhanced, so as to facilitate the driver to identify whether the vehicle has a flat tire.

[0079] In this embodiment, when the flat tire auxiliary recognition function is turned on, the ambient sound data is collected through the in-vehicle microphone; the ambient sound data is filtered by high frequency to obtain the filtered audio data, and the filtered audio data is used to form an enhanced sound effect with the ambient sound transmitted to the vehicle driver's ear; the filtered audio data is played through the in-vehicle audio to assist the vehicle driver in identifying a flat tire. Since the ambient sound data is collected through the in-vehicle microphone, and the high-frequency sounds such as human voices, singing, and whistles are filtered, and the filtered audio data after filtering is played through the in-vehicle audio, the low-frequency part of the ambient sound can be enhanced, making it easier for the driver to identify the sound when a flat tire occurs.

[0080] Refer to Figure 6 , Figure 6 It is a schematic flowchart of the second embodiment of a flat tire auxiliary recognition method of the present invention.

[0081] Based on the above first embodiment, step S10 of the flat tire auxiliary recognition method in this embodiment includes:

[0082] Step S101: When the flat tire auxiliary recognition function is turned on, obtain the position data and / or navigation route data of the vehicle.

[0083] It should be noted that if the puncture assistance recognition function is enabled, it means that the driver hopes that the vehicle can assist the driver in determining a puncture through the puncture assistance recognition function to avoid misjudgment or missed judgment of the vehicle's puncture phenomenon. However, the puncture assistance recognition function will partially enhance the ambient sound. If it is continuously executed, it may affect the driver's listening to music and communicating with others, and may even miss the horn reminder from the vehicle behind. Therefore, the assistance recognition can be performed only when the vehicle is about to arrive at or is in an area where punctures are likely to occur. At this time, the vehicle navigation data and position data can be obtained to assist in judging whether the vehicle is about to arrive at or is in an area where punctures are likely to occur.

[0084] Among them, the vehicle navigation data can be obtained through the navigation software or navigation module in the vehicle; the position data can be obtained through the positioning module in the vehicle. The positioning module can be a GPS positioning module or other similar functional modules. This embodiment does not limit this.

[0085] Step S102: Determine whether the vehicle is about to pass through or is in a puncture risk area according to the position data and / or the navigation route data.

[0086] It should be noted that the puncture risk area can be an area under construction or an area with a lot of sand and gravel. The navigation route data can be the relevant data of the navigation route obtained from a third-party navigation software, which includes the position information of the puncture risk area that the navigation route will pass through.

[0087] In a specific implementation, determining whether the vehicle is about to pass through or is in a puncture risk area according to the position data and / or the navigation route data can be to determine whether the position data is in the puncture risk area. If so, it is determined that the vehicle is in the puncture risk area. If not, the driving distance of the vehicle entering the puncture risk area can be calculated according to the navigation route data and the position data. When the driving distance is less than or equal to a preset interval threshold, it is determined that the vehicle is about to pass through the puncture risk area. Among them, the preset interval threshold can be pre-set by the management personnel of the puncture assistance recognition device. Different preset interval thresholds can be set according to different vehicle speeds, and the vehicle speed is proportional to the preset interval threshold.

[0088] Step S103: If it is about to pass through or is in a puncture risk area, collect ambient sound data through the in-vehicle microphone.

[0089] It can be understood that if the vehicle is about to pass through or is in a puncture risk area, it means that the vehicle has a puncture risk. Therefore, the ambient sound data can be collected through the in-vehicle microphone, and the subsequent steps can be executed to assist the driver of the vehicle in puncture recognition.

[0090] In a specific implementation, in order to let the driver know that the vehicle has started audio processing, before collecting ambient sound data through the in-vehicle microphone, voice broadcast can also be performed and / or corresponding icons can be lit on the vehicle's instrument panel.

[0091] Furthermore, in order to determine as accurately as possible whether audio processing is required and assist in judging whether a flat tire occurs, after step S102 of this embodiment, the following steps may further be included:

[0092] If it is not about to pass through a flat tire risk area, obtain the vehicle accident data corresponding to the navigation route data;

[0093] Determine whether the vehicle is about to pass through or is in a high-incidence area of flat tire accidents according to the position data, the vehicle accident data, and the navigation route data;

[0094] If it is about to pass through or is in a high-incidence area of flat tire accidents, collect ambient sound data through the in-vehicle microphone.

[0095] It should be noted that the vehicle accident data corresponding to the navigation route data may be the accident data of vehicles that occurred within a previously preset time period in the area related to the navigation route corresponding to the navigation route data.

[0096] It should be understood that according to the vehicle accident data, corresponding high-incidence areas of flat tire accidents can be marked on the navigation route included in the navigation route data, and then it is determined whether the vehicle is in a high-incidence area of flat tire accidents according to the position data. If so, it is determined that the vehicle is in a high-incidence area of flat tire accidents; if not, calculate the driving distance of the vehicle entering the high-incidence area of flat tire accidents according to the position information and the navigation route data, and when the driving distance is less than or equal to the preset interval threshold, it is determined that the vehicle is about to pass through the high-incidence area of flat tire accidents.

[0097] It can be understood that if the vehicle is about to pass through or is in a high-incidence area of flat tire accidents, it means that the vehicle has a flat tire risk. Therefore, ambient sound data can be collected through the in-vehicle microphone and subsequent steps can be executed to assist the driver of the vehicle in flat tire identification.

[0098] In the specific implementation process, in order to ensure safety, the priority of manual operation should be the highest. Therefore, after the step of determining whether the vehicle is about to pass through or is in a high-incidence area of flat tire accidents according to the position data, the vehicle accident data, and the navigation route data of this embodiment, the following steps may further be included:

[0099] If it is not about to pass through or is in a high-incidence area of flat tire accidents, but it is detected that the driver performs an auxiliary identification activation operation, collect ambient sound data through the in-vehicle microphone.

[0100] It can be understood that, in order to ensure the safety during driving, the operation of the driver should be given the highest priority. At this time, although the detection result indicates that the vehicle is not about to pass through or is not in a flat tire risk area and / or a high-incidence area of flat tire accidents, if the driver performs the auxiliary recognition activation operation, it means that the driver determines that there is a flat tire risk based on his own experience. In this case, environmental sound data can be collected through the on-vehicle microphone, and subsequent steps can be executed to assist the driver of the vehicle in flat tire recognition.

[0101] In this embodiment, when the flat tire auxiliary recognition function is activated, the position data and / or navigation route data of the vehicle are obtained; based on the position data and / or the navigation route data, it is determined whether the vehicle is about to pass through or is in a flat tire risk area; if it is about to pass through or is in a flat tire risk area, environmental sound data is collected through the on-vehicle microphone. Since the flat tire auxiliary recognition function is not continuously executed, but only when it is determined that the vehicle is about to pass through or is in a flat tire risk area, that is, when there is a flat tire risk for the vehicle, environmental sound data is collected through the on-vehicle microphone and the flat tire auxiliary recognition function is executed, so as to minimize the impact on the normal driving of the driver.

[0102] Reference Figure 7 , Figure 7 is a schematic flowchart of the third embodiment of a flat tire auxiliary recognition method of the present invention.

[0103] Based on the above first embodiment, after the step S30 of this embodiment of the flat tire auxiliary recognition method, it further includes:

[0104] Step S40: Obtain the navigation route data of the vehicle and the vehicle accident data corresponding to the navigation route data.

[0105] It should be noted that during the process of processing and playing the audio to assist the driver in flat tire recognition, the navigation route data of the vehicle and the vehicle accident data corresponding to the navigation route data can also be continuously monitored.

[0106] Step S50: Based on the current positioning data, the navigation route data and the vehicle accident data of the vehicle, determine whether the vehicle has left the flat tire risk area and the high-incidence area of flat tire accidents.

[0107] It should be noted that the current positioning data can be the position data of the vehicle at the current moment.

[0108] In a specific implementation, the flat tire risk areas in the navigation route can be extracted from the navigation route data, and the areas with a high incidence of flat tire accidents can be marked in the navigation route according to the vehicle accident data. According to the current positioning data and the navigation route, it can be determined whether the vehicle has driven out of the area ranges of the flat tire risk areas and the areas with a high incidence of flat tire accidents. If the vehicle has driven out of the area ranges of the flat tire risk areas and the areas with a high incidence of flat tire accidents, it can be determined that the vehicle has left the flat tire risk areas and the areas with a high incidence of flat tire accidents.

[0109] Step S60: If so, stop executing the flat tire auxiliary recognition function.

[0110] It can be understood that if the vehicle has left the flat tire risk areas and the areas with a high incidence of flat tire accidents, the flat tire risk of the vehicle is relatively low. At this time, the flat tire auxiliary recognition function can be stopped from being executed, and the environmental sound data is no longer collected, nor is the in-vehicle audio used for playback, so as not to affect the normal driving of the driver and ensure the driver's usage experience.

[0111] Furthermore, since the flat tire auxiliary recognition function may be manually executed by the user, directly stopping the execution of the flat tire auxiliary recognition function at this time will result in a reduction in the user experience. To avoid this phenomenon, step S60 in this embodiment may include:

[0112] If so, obtain the execution mode of the flat tire auxiliary recognition function;

[0113] If the execution mode is automatic execution, stop executing the flat tire auxiliary recognition function.

[0114] It should be noted that the execution mode is divided into two modes: automatic execution and manual execution. If the environmental sound data is collected through the in-vehicle microphone when it is detected that the vehicle is about to pass through or is in the flat tire risk area and / or the area with a high incidence of flat tire accidents, the execution mode is automatic execution; if the environmental sound data is collected through the in-vehicle microphone when it is detected that the driver executes the auxiliary recognition activation operation, the execution mode is manual execution.

[0115] It can be understood that if the execution mode is automatic execution, it means that at this time, it is not the driver who manually confirms that the flat tire auxiliary recognition function needs to be executed. Therefore, the flat tire auxiliary recognition function can be directly stopped, the environmental sound data is no longer collected, nor is the in-vehicle audio used for playback, so as not to affect the normal driving of the driver and ensure the driver's usage experience. In order to make the driver clearly aware that the flat tire auxiliary recognition function has been stopped, the flat tire auxiliary recognition device can control the vehicle to broadcast a corresponding voice prompt or turn off the relevant display icons.

[0116] In a specific implementation, to ensure that the tire puncture assistance recognition function can be normally managed even when the execution mode is manual execution, after the step of obtaining the execution mode of the tire puncture assistance recognition function in this embodiment, the following may further be included:

[0117] If the execution mode is manual execution, obtain the continuous execution duration of the tire puncture assistance recognition function;

[0118] If the continuous execution duration is greater than a preset continuous threshold, or it is detected that the driver executes an auxiliary recognition stop operation, stop executing the tire puncture assistance recognition function.

[0119] It should be noted that the preset continuous threshold can be set in advance by the management personnel of the tire puncture assistance recognition device. For example, the preset continuous threshold is set to 10 minutes.

[0120] In actual use, generally vehicles do not drive in tire puncture risk areas and high-incidence areas of tire puncture accidents for a long time. Therefore, if the continuous execution duration of the tire puncture assistance recognition function is greater than the preset continuous threshold, it means that the tire puncture assistance recognition function has run continuously for a long enough time. Therefore, at this time, the tire puncture assistance recognition function can be stopped. Of course, to ensure the actual use experience of the driver, before stopping the execution of the tire puncture assistance recognition function, the driver can be asked whether to stop the execution in the form of a pop-up window on the vehicle's central control screen, and then stop the execution of the tire puncture assistance recognition function after the user confirms.

[0121] It can be understood that if the execution mode is manual execution and the driver executes an auxiliary recognition stop operation, it means that the driver determines that there is no longer a tire puncture risk for the vehicle. Therefore, the tire puncture assistance recognition function can be directly stopped.

[0122] In this embodiment, by obtaining the navigation route data of the vehicle and the vehicle accident data corresponding to the navigation route data; determining whether the vehicle has left the tire puncture risk area and the high-incidence area of tire puncture accidents according to the current positioning data of the vehicle, the navigation route data and the vehicle accident data; if so, stop executing the tire puncture assistance recognition function. Since the driving situation of the vehicle is continuously detected, after the vehicle leaves the tire puncture risk area and the high-incidence area of tire puncture accidents, the tire puncture assistance recognition function is stopped in time, minimizing the impact on the driver's normal driving as much as possible.

[0123] Reference Figure 7 , Figure 7 is a schematic flowchart of the fourth embodiment of a tire puncture assistance recognition method of the present invention.

[0124] Based on the above first embodiment, before the step S10 of this embodiment of the tire puncture assistance recognition method, the following is further included:

[0125] Step S01: Obtain the position data and / or navigation route data of the vehicle;

[0126] Step S02: Determine whether the vehicle is about to pass through or is in a flat tire risk area according to the vehicle positioning data and / or the navigation route data;

[0127] Step S03: If it is about to pass through or is in a flat tire risk area, turn on the flat tire auxiliary recognition function.

[0128] It should be noted that the method for determining whether the vehicle is about to pass through or is in a flat tire risk area is basically the same as the determination method in the above second embodiment, and will not be elaborated here.

[0129] It can be understood that if the vehicle is about to pass through or is in a flat tire risk area, it means that the vehicle has a flat tire risk. At this time, the flat tire auxiliary recognition function can be automatically turned on and the subsequent steps can be executed to assist the driver of the vehicle in flat tire recognition.

[0130] In a specific implementation, if it is determined that the vehicle is not about to pass through or is in a flat tire risk area, the vehicle accident data can also be obtained to determine whether the vehicle is about to pass through or is in a high-incidence area of flat tire accidents. If so, the flat tire auxiliary recognition function can be turned on and the subsequent steps can be executed to assist the driver of the vehicle in flat tire recognition.

[0131] Of course, in order to ensure the actual use experience of the user, when it is determined that the vehicle is about to pass through or is in a flat tire risk area, a pop-up window or voice prompt can be given to the driver to prompt the driver to turn on the flat tire auxiliary recognition function. After the driver determines to turn it on, the flat tire auxiliary recognition function is then turned on.

[0132] In this embodiment, when it is determined that the vehicle is about to pass through or is in a flat tire risk area, that is, when the vehicle has a flat tire risk, the flat tire auxiliary recognition function can be automatically turned on to facilitate the driver to identify whether the vehicle has a flat tire.

[0133] In addition, an embodiment of the present invention also proposes a storage medium, on which a flat tire auxiliary recognition program is stored. When the flat tire auxiliary recognition program is executed by a processor, the steps of the flat tire auxiliary recognition method as described above are implemented.

[0134] Refer to Figure 9 , Figure 9 is the structural block diagram of the first embodiment of the flat tire auxiliary recognition device of the present invention.

[0142] Furthermore, the data acquisition module 10 is further configured to, if it is not about to pass through or is in a high-incidence area of flat tire accidents, but it is detected that the driver performs an auxiliary identification activation operation, collect ambient sound data through the in-vehicle microphone.

[0143] Furthermore, the audio playback module 30 is further configured to obtain the navigation route data of the vehicle and the vehicle accident data corresponding to the navigation route data; determine whether the vehicle has left the flat tire risk area and the high-incidence area of flat tire accidents according to the current positioning data of the vehicle, the navigation route data, and the vehicle accident data; if so, stop executing the flat tire assistance identification function.

[0144] Further, the audio playback module 30 is further configured to, if so, obtain the execution mode of the flat tire auxiliary recognition function; if the execution mode is automatic execution, stop executing the flat tire auxiliary recognition function.

[0145] Further, the audio playback module 30 is further configured to, if the execution mode is manual execution, obtain the continuous execution duration of the flat tire auxiliary recognition function; if the continuous execution duration is greater than a preset continuous threshold, or it is detected that the driver executes an auxiliary recognition stop operation, stop executing the flat tire auxiliary recognition function.

[0146] Further, the data acquisition module 10 is further configured to obtain the position data of the vehicle and / or the navigation route data; determine whether the vehicle is about to pass through or is in a flat tire risk area according to the vehicle positioning data and / or the navigation route data; if it is about to pass through or is in a flat tire risk area, enable the flat tire auxiliary recognition function.

[0147] Further, the data acquisition module 10 is further configured to, when the auxiliary recognition function is enabled, control the vehicle window to open and / or reduce the volume of the in-vehicle multimedia; collect ambient sound data through the in-vehicle microphone.
