[0002] This application relates to the field of vehicle technology, and in particular to a method, apparatus, vehicle, and storage medium for arranging a vehicle noise warning system. Background Technology

[0003] With increasing environmental awareness and the pursuit of sustainable energy, electric vehicles have become the main direction of future automotive development due to their zero-emission advantage. Compared with gasoline vehicles, electric vehicles have advantages such as energy saving and quick start-up, but they also have drawbacks. For example, electric vehicles emit a low-speed warning sound when driving at low speeds. This warning sound is too noisy and affects the user's comfort experience. Therefore, it is necessary to optimize the warning sound emitted by electric vehicles when driving at low speeds while ensuring driving safety.

[0004] In related technologies, there is a lack of explanation on optimizing the warning sound when electric vehicles are driving at low speeds. As a result, when electric vehicles emit a low-speed warning sound, the noise will reduce the user's driving experience. This problem urgently needs to be solved. Summary of the Invention

This solves the problem of noise generated by the vehicle emitting a low-speed warning sound when the vehicle is traveling at low speed, thus reducing the user's driving experience. Furthermore, since the noise characteristics inside the vehicle and the noise transmission loss outside the vehicle are considered when determining the final arrangement position of the vehicle noise warning system, installing the vehicle noise warning system at that final arrangement position can reduce vehicle interior noise and improve the user's driving experience.

[0047] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0048] The following description, with reference to the accompanying drawings, outlines a method, apparatus, vehicle, and storage medium for arranging a vehicle noise warning system according to embodiments of this application. Addressing the problem mentioned in the background art where noise generated by a vehicle emitting a low-speed warning sound during low-speed driving reduces the user's driving experience, this application provides a method for arranging a vehicle noise warning system. In this method, at least one initial arrangement position for the vehicle noise warning system is determined. Based on each initial arrangement position, corresponding vehicle interior noise information and vehicle exterior noise information are collected. Noise feature analysis is performed on the vehicle interior noise information to obtain noise feature analysis results. Noise transmission loss simulation analysis is performed on the vehicle exterior noise information to obtain noise transmission loss simulation analysis results. The final arrangement position of the vehicle noise warning system is determined based on the noise feature analysis results and the noise transmission loss simulation analysis results. Therefore, this application can analyze the vehicle interior noise information and vehicle exterior noise information collected at each initial placement location to determine the final placement location of the vehicle noise warning system. This solves the problem of noise generated by the vehicle emitting a low-speed warning sound when the vehicle is traveling at low speed, thereby reducing the user's driving experience. Furthermore, since the noise characteristics inside the vehicle and the noise transmission loss outside the vehicle are considered when determining the final placement location of the vehicle noise warning system, installing the vehicle noise warning system at this final placement location can reduce vehicle interior noise and improve the user's driving experience.

[0049] Specifically, Figure 1 is a flowchart illustrating a method for arranging a vehicle noise warning system according to an embodiment of this application. The executing entity in this embodiment can be a vehicle or a vehicle controller within the vehicle; as shown in Figure 1, the method for arranging the vehicle noise warning system includes the following steps:

[0050] In step S101, at least one initial placement location of the vehicle noise warning system is determined.

[0051] Specifically, to address the issue of reduced passenger comfort due to vehicle noise caused by warning sounds during driving, this application embodiment primarily utilizes an ATF (Automated Test Facility) to test the sound emitted at a pre-selected installation location. The test measures both internal and external vehicle noise information, thereby determining the final placement location of the vehicle noise warning system based on this information. The vehicle noise warning system can be an AVAS (Acoustic Vehicle Alerting System). Accordingly, in this step, by adjusting the placement of the AVAS system, the warning sounds generated by the AVAS system are attenuated as much as possible before entering the vehicle, thus addressing the issue of high interior noise. Therefore, based on the design characteristics and installation feasibility of different vehicle models, at least one suitable initial placement location for installing the vehicle noise warning system, i.e., the AVAS system, is selected as a pre-selected installation location. This pre-selected installation location typically includes, but is not limited to, the front bumper, rear bumper, and side of the vehicle body.

[0052] In step S102, based on each initial arrangement position, the vehicle interior noise information and the vehicle exterior noise information corresponding to each initial arrangement position are collected.

[0053] Specifically, after determining at least one initial placement location, it is necessary to collect vehicle interior noise information and vehicle exterior noise information corresponding to each initial placement location.

[0054] For each initial placement location, the vehicle interior noise information corresponding to that initial placement location refers to the noise information collected inside the vehicle when the noise alert system is installed at that initial placement location; the noise information collected inside the vehicle can be the noise information collected at the first measuring point inside the vehicle. The vehicle exterior noise information corresponding to that initial placement location refers to the noise information collected outside the vehicle when the noise alert system is installed at that initial placement location; the noise information collected outside the vehicle can be the noise information collected at the second measuring point outside the vehicle.

[0055] Specifically, to understand the impact of the noise alert system's emitted tone on vehicle interior noise at each initial placement location, this embodiment requires emitting sound at each initial placement location using an ATF test, and then collecting vehicle interior and exterior noise information to obtain the corresponding vehicle interior and exterior noise information for each initial placement location. The vehicle interior noise information clarifies the main sources of current vehicle interior noise, their frequency distribution, and intensity, thus helping to identify which frequency bands are most likely to affect user comfort. Simultaneously, to understand the specific impact of the noise alert emitted at each initial placement location on vehicle interior noise, and based on the vehicle exterior noise information, it predicts how much attenuation the noise alert emitted from that initial placement location will undergo before reaching the vehicle interior. Based on this attenuation, it aims to minimize unnecessary noise entering the vehicle while ensuring that pedestrians outside can clearly hear the alert.

[0056] In step S103, noise feature analysis is performed on the vehicle interior noise information to obtain the noise feature analysis results of the vehicle interior noise information corresponding to each initial placement position. Noise transmission loss simulation analysis is performed on the vehicle exterior noise information to obtain the noise transmission loss simulation analysis results of the vehicle exterior noise information corresponding to each initial placement position. Based on the noise feature analysis results and the noise transmission loss simulation analysis results, the final placement position of the vehicle noise warning system is determined.

[0057] According to one embodiment of this application, noise feature analysis is performed on vehicle interior noise information to obtain noise feature analysis results for vehicle interior noise information corresponding to each initial arrangement position. This includes: using a preset noise analysis method, performing a first preset number of noise feature analyses on the vehicle interior noise information corresponding to each initial arrangement position to obtain the vehicle interior noise frequency distribution and amplitude characteristics corresponding to each initial arrangement position after each noise feature analysis; determining the average noise frequency distribution and average amplitude characteristics based on the vehicle interior noise frequency distribution and amplitude characteristics corresponding to each initial arrangement position after each noise analysis; and obtaining the noise feature analysis results for vehicle interior noise information corresponding to each initial arrangement position based on the average noise frequency distribution and average amplitude characteristics.

[0058] Noise frequency distribution describes the distribution of noise power at different frequencies; the amplitude characteristics of noise reflect the statistical regularity of the instantaneous noise value deviating from the average value.

[0059] For each initial arrangement position, a preset noise analysis method is used to perform a first preset number of noise feature analyses on the vehicle interior noise information corresponding to that initial arrangement position, obtaining the first preset number of vehicle interior noise frequency distributions and amplitude characteristics, determining the average value of the first preset number of vehicle interior noise frequency distributions and amplitude characteristics, obtaining the average noise frequency distribution and average amplitude characteristics, and determining the average noise frequency distribution and average amplitude characteristics as the noise feature analysis results of the vehicle interior noise information corresponding to that initial arrangement position.

[0060] According to one embodiment of this application, noise transmission loss simulation analysis is performed on vehicle external noise information to obtain the noise transmission loss simulation analysis result of vehicle external noise information corresponding to each initial placement position. This includes: using a preset noise loss simulation analysis method, performing a second preset number of noise transmission loss simulation analyses on the vehicle external noise information corresponding to each initial placement position to obtain the noise transmission loss value corresponding to each initial placement position after each noise transmission loss simulation analysis; determining the average noise transmission loss value based on the noise transmission loss value corresponding to each initial placement position after each noise transmission loss simulation analysis, and filtering the average noise transmission loss values ​​corresponding to each initial placement position to determine the maximum average noise transmission loss value; and obtaining the noise transmission loss simulation analysis result of vehicle external noise information corresponding to each initial placement position based on the maximum average noise transmission loss value.

[0061] For each initial placement location, a preset noise loss simulation analysis method is used to perform a second preset number of noise transmission loss simulation analyses on the vehicle's external noise information corresponding to that initial placement location, obtaining a second preset number of noise transmission loss values. The average value of the second preset number of noise transmission loss values ​​is then determined to obtain the average noise transmission loss value. Since there is at least one initial placement location, at least one average noise transmission loss value corresponding to each initial placement location is obtained. Based on the average noise transmission loss values ​​corresponding to each of the at least one initial placement location, the maximum average noise transmission loss value is determined, and the maximum average noise transmission loss value is taken as the result of the noise transmission loss simulation analysis.

[0062] According to one embodiment of this application, noise transmission loss simulation analysis is performed on vehicle external noise information to obtain the noise transmission loss simulation analysis result of vehicle external noise information corresponding to each initial placement position. This includes: using a preset noise loss simulation analysis method, performing a second preset number of noise transmission loss simulation analyses on the vehicle external noise information corresponding to each initial placement position to obtain the noise transmission loss value corresponding to each initial placement position after each noise transmission loss simulation analysis; determining an average noise transmission loss value based on the noise transmission loss value corresponding to each initial placement position after each noise transmission loss simulation analysis; and obtaining the noise transmission loss simulation analysis result of vehicle external noise information corresponding to each initial placement position based on the average noise transmission loss value.

[0063] For each initial placement location, a preset noise loss simulation analysis method is used to perform a second preset number of noise characteristic analyses on the vehicle's external noise information corresponding to that initial placement location, obtaining the second preset number of vehicle external noise transmission loss values, determining the average value of the first preset number of vehicle external noise loss values, obtaining the average noise transmission loss value, and determining the average noise transmission loss value as the noise transmission loss simulation analysis result of the vehicle's external noise information corresponding to that initial placement location.

[0064] The first and second preset number of tests can be set by those skilled in the art according to actual testing needs, and no specific limitations are made here.

[0065] Specifically, in this embodiment, it is necessary to perform noise characteristic analysis inside the vehicle and noise transmission loss simulation analysis outside the vehicle based on each initial arrangement position.

[0066] Specifically, firstly, in order to more accurately capture the noise characteristics within a specific frequency range, this embodiment can utilize a preset noise analysis method, such as a 1 / 3 octave band analysis method, to confirm the noise frequency distribution and amplitude characteristics generated within the vehicle at each initial placement location. This allows for a more accurate identification of the main frequency components of the noise within the vehicle and their corresponding intensities, thereby helping to determine the specific source of the noise (such as engine noise, wind noise, road noise, etc.). Secondly, using a preset noise loss simulation analysis method, noise transmission loss simulation analysis is performed on the external noise information corresponding to each initial placement location. This further refines and verifies the noise transmission loss characteristics of each initial placement location, ensuring its accuracy. To effectively reduce in-vehicle noise, this embodiment should maximize the noise transmission loss (i.e., minimize the noise entering the vehicle). In other words, the initial placement location that minimizes in-vehicle noise is selected. At this point, the final placement location of the vehicle noise warning system can be determined based on the noise characteristic analysis results of the internal vehicle noise information and the noise transmission loss simulation analysis results of the external vehicle noise information. This effectively reduces in-vehicle noise while ensuring that pedestrians outside can clearly hear the warning sound.

[0067] Furthermore, in order to prevent random errors that may occur in a single test due to environmental factors, equipment status, or human operation, the embodiments of this application can perform multiple repeated tests. That is, when performing noise characteristic analysis on the noise information inside the vehicle and noise transmission loss simulation analysis on the noise information outside the vehicle, multiple repeated tests can be performed to ensure the accuracy of the test.

[0068] Specifically, firstly, using the 1 / 3 octave band analysis method, noise feature analysis is performed on the vehicle interior noise information corresponding to each initial arrangement position for a first preset number of times. This yields the frequency distribution and amplitude characteristics of the vehicle interior noise corresponding to each initial arrangement position after each noise feature analysis. Then, the average frequency distribution and average amplitude characteristics of the vehicle interior noise corresponding to each initial arrangement position after each noise analysis are further determined. Based on the average noise frequency distribution and average amplitude characteristics, the noise feature analysis results of the vehicle interior noise information corresponding to each initial arrangement position are obtained.

[0069] Secondly, using a pre-defined noise loss simulation analysis method, a second pre-defined number of noise transmission loss simulation analyses are performed on the vehicle's external noise information corresponding to each initial placement position. This yields the noise transmission loss value for each initial placement position after each noise transmission loss simulation analysis. Then, the average noise transmission loss value for each initial placement position after each noise transmission loss simulation analysis is further determined. The average noise transmission loss value for each initial placement position is then filtered. Since the maximum noise transmission loss means the least amount of sound entering the vehicle, it is necessary to determine the maximum average noise transmission loss value. Based on the maximum average noise transmission loss value, the noise transmission loss simulation analysis results for the vehicle's external noise information corresponding to each initial placement position are obtained.

[0070] It should be noted that when performing vehicle interior noise characteristic analysis and vehicle exterior noise transmission loss simulation analysis, information such as the standard deviation of each noise characteristic analysis and noise transmission loss simulation analysis can be recorded. This can help assess the consistency between different analysis results. If the standard deviation is small, it indicates that the analysis results are relatively concentrated, suggesting that the data at this location is stable and predictable. Conversely, if the standard deviation is large, it may mean that some uncontrolled variables have affected the analysis results. This helps to identify and eliminate potential analysis errors or special cases, thereby improving the reliability of the analysis results.

[0071] According to one embodiment of this application, the final placement location of the vehicle noise warning system is determined based on the noise characteristic analysis results and the noise transmission loss simulation analysis results, including: determining the final placement location of the vehicle noise warning system based on the average noise frequency distribution and average amplitude characteristics, as well as the maximum average noise transmission loss value.

[0072] According to one embodiment of this application, determining the final placement location of the vehicle noise warning system based on the average noise frequency distribution, average amplitude characteristics, and the maximum average noise transmission loss value includes:

[0073] Based on the average noise frequency distribution corresponding to each initial placement position, at least one candidate placement position corresponding to the target noise frequency is determined, where the target noise frequency is a noise frequency that does not affect user comfort; from the at least one candidate placement position, the final placement position is determined where the average amplitude characteristic is less than the first preset amplitude characteristic and the average noise transmission loss value is the maximum average noise transmission loss value.

[0074] Specifically, as shown in Figure 2, based on the noise characteristic analysis results of the vehicle interior noise information and the noise transmission loss simulation analysis results of the vehicle exterior noise information, the final placement position of the vehicle noise warning system can be determined. That is, by using the average noise frequency distribution and average amplitude characteristics of the vehicle interior corresponding to each initial placement position, and the maximum average noise transmission loss value determined after filtering the average noise transmission loss value corresponding to each initial placement position, the final placement position of the vehicle noise warning system is determined. In other words, the optimal placement position that minimizes the noise inside the vehicle is determined, thereby effectively reducing the noise inside the vehicle while ensuring that pedestrians outside can clearly hear the warning sound, achieving the goal of both ensuring the safety of pedestrians outside and improving the comfort of users inside the vehicle.

[0075] According to one embodiment of this application, the final placement location of the vehicle noise warning system is determined based on the noise feature analysis results and the noise transmission loss simulation analysis results, including: determining the final placement location of the vehicle noise warning system based on the average noise frequency distribution and average amplitude characteristics corresponding to each initial placement location, and the average noise transmission loss value corresponding to each initial placement location.

[0076] Based on the average noise frequency distribution corresponding to each initial placement position, at least one candidate placement position corresponding to the target noise frequency is determined, where the target noise frequency is a noise frequency that does not affect user comfort; based on the average assignment characteristics and average noise transmission loss value corresponding to each candidate placement position, the noise assignment characteristics corresponding to each candidate placement position are determined; based on the noise amplitude characteristics corresponding to each candidate placement position, the final placement position is determined.

[0077] Based on the average assignment characteristics and average noise transmission loss value corresponding to each candidate placement location, the noise assignment characteristics corresponding to each candidate placement location are determined, including:

[0078] For each candidate arrangement location, based on the average noise transmission loss value and the external noise amplitude characteristics corresponding to the candidate arrangement location, the additional noise assignment characteristics corresponding to the candidate arrangement location are determined. The external noise assignment characteristics are the amplitude characteristics corresponding to the vehicle's external noise information, and the additional noise amplitude characteristics are the noise assignment characteristics of the external noise information transmitted to the vehicle's interior. The sum of the average assignment characteristics and the additional noise assignment characteristics corresponding to the candidate arrangement location is determined to obtain the noise assignment characteristics corresponding to the candidate arrangement location.

[0079] The final placement position is determined based on the noise amplitude characteristics corresponding to each candidate placement position, including: determining the candidate placement position corresponding to the minimum noise assignment characteristic based on the noise amplitude characteristics corresponding to each candidate placement position, and determining the candidate placement position as the final placement position.

[0080] Preferably, in this embodiment of the application, the final placement position can be the front bumper of the vehicle. After testing and analysis, the AVAS system can be installed on the front bumper while meeting the requirements of regulations, and the noise inside the vehicle can be reduced to the maximum extent.

[0081] According to one embodiment of this application, after determining the final placement location of the vehicle noise warning system based on the noise feature analysis results and the noise transmission loss simulation analysis results, the method further includes: optimizing the noise warning sound source of the vehicle noise warning system based on the noise transmission loss simulation analysis results.

[0082] The noise warning sound source of the vehicle noise warning system is optimized based on the simulation analysis results of noise transmission loss, including: noise reduction processing of the noise warning sound source of the vehicle noise warning system based on the simulation analysis results of noise transmission loss.

[0083] Specifically, as shown in Figure 3, after determining the final placement location of the vehicle noise warning system based on the noise characteristic analysis results and the noise transmission loss simulation analysis results, the noise warning sound source of the vehicle noise warning system is optimized based on the maximum average noise transmission loss value of the final placement location. For example, the AVAS sound source is optimized to ensure that the transmission loss of the AVAS sound to the human ear inside the vehicle is maximized.

[0084] In summary, based on the specific implementation methods described above, the embodiments of this application can achieve the following beneficial effects:

[0085] (1) By accurately analyzing the frequency distribution and amplitude characteristics of noise inside the vehicle and conducting simulation analysis of noise transmission loss, we can ensure that the transmission loss of the warning sound of the vehicle noise warning system to the ear inside the vehicle is maximized, thereby determining the optimal installation location of the vehicle noise warning system. This can effectively reduce unnecessary noise inside the vehicle, improve the user's comfort experience and the safety of pedestrians outside the vehicle.

[0086] (2) By comprehensively considering noise transmission loss, noise frequency distribution and amplitude characteristics, the optimal installation location of the vehicle noise warning system is selected, so that the system can maximize the external sound transmission efficiency while minimizing in-vehicle noise, thereby achieving higher system performance.

[0087] According to the vehicle noise warning system arrangement method of this application embodiment, at least one initial arrangement position of the vehicle noise warning system is determined. Based on each initial arrangement position, corresponding vehicle interior noise information and vehicle exterior noise information are collected. Noise feature analysis is performed on the vehicle interior noise information to obtain noise feature analysis results. Noise transmission loss simulation analysis is performed on the vehicle exterior noise information to obtain noise transmission loss simulation analysis results. Based on the noise feature analysis results and the noise transmission loss simulation analysis results, the final arrangement position of the vehicle noise warning system is determined. Therefore, this application can analyze the vehicle interior noise information and vehicle exterior noise information collected at each initial arrangement position to determine the final arrangement position of the vehicle noise warning system. This solves the problem of noise generated by the vehicle emitting a low-speed warning sound when the vehicle is traveling at low speed, thus reducing the user's driving experience. Furthermore, since the noise characteristics inside the vehicle and the noise transmission loss outside the vehicle are considered when determining the final arrangement position of the vehicle noise warning system, installing the vehicle noise warning system at that final arrangement position can reduce vehicle interior noise and improve the user's driving experience.

[0088] Next, the arrangement of the vehicle noise warning system according to the embodiments of this application is described with reference to the accompanying drawings.

[0089] Figure 4 is a block diagram of the arrangement of the vehicle noise warning system according to an embodiment of this application.

[0090] As shown in Figure 4, the arrangement device 10 of the vehicle noise warning system includes: a first determining module 100, a data acquisition module 200, and a second determining module 300.

[0091] The first determining module 100 is used to determine at least one initial placement position of the vehicle noise warning system.

[0092] The acquisition module 200 is used to acquire vehicle interior noise information and vehicle exterior noise information corresponding to each initial arrangement position based on each initial arrangement position.

[0093] The second determining module 300 is used to perform noise feature analysis on the vehicle interior noise information to obtain the noise feature analysis results of the vehicle interior noise information corresponding to each initial placement position, perform noise transmission loss simulation analysis on the vehicle exterior noise information to obtain the noise transmission loss simulation analysis results of the vehicle exterior noise information corresponding to each initial placement position, and determine the final placement position of the vehicle noise warning system based on the noise feature analysis results and the noise transmission loss simulation analysis results.

[0094] According to one embodiment of this application, the second determining module 200 is specifically used for:

[0095] Using a preset noise analysis method, the noise feature analysis of the vehicle interior noise information corresponding to each initial arrangement position is performed for a first preset number of times to obtain the frequency distribution and amplitude characteristics of the vehicle interior noise corresponding to each initial arrangement position after each noise feature analysis.

[0096] Based on the frequency distribution and amplitude characteristics of the vehicle's interior noise at each initial placement position after each noise analysis, the average noise frequency distribution and average amplitude characteristics are determined, and the noise characteristic analysis results of the vehicle's interior noise information at each initial placement position are obtained based on the average noise frequency distribution and average amplitude characteristics.

[0097] According to one embodiment of this application, the second determining module 200 is specifically used for:

[0098] Using a preset noise loss simulation analysis method, the external noise information of the vehicle corresponding to each initial arrangement position is subjected to a second preset number of noise transmission loss simulation analyses to obtain the noise transmission loss value corresponding to each initial arrangement position after each noise transmission loss simulation analysis.

[0099] Based on the noise transmission loss values ​​corresponding to each initial placement position after each noise transmission loss simulation analysis, the average noise transmission loss value is determined. The average noise transmission loss values ​​corresponding to each initial placement position are then filtered to determine the maximum average noise transmission loss value. Based on the maximum average noise transmission loss value, the noise transmission loss simulation analysis results of the vehicle external noise information corresponding to each initial placement position are obtained.

[0100] According to one embodiment of this application, the noise characteristic analysis results include the average noise frequency distribution and average amplitude characteristics inside the vehicle corresponding to each initial arrangement position, and the noise transmission loss simulation analysis results include the maximum average noise transmission loss value determined after filtering the average noise transmission loss values ​​corresponding to each initial arrangement position; the second determining module 200 is specifically used for:

[0103] The noise warning sound source of the vehicle noise warning system is optimized based on the simulation analysis results of noise transmission loss.

[0104] According to the vehicle noise warning system arrangement device of this application embodiment, at least one initial arrangement position of the vehicle noise warning system is determined. Based on each initial arrangement position, corresponding vehicle interior noise information and vehicle exterior noise information are collected. Noise feature analysis is performed on the vehicle interior noise information to obtain noise feature analysis results. Noise transmission loss simulation analysis is performed on the vehicle exterior noise information to obtain noise transmission loss simulation analysis results. Based on the noise feature analysis results and the noise transmission loss simulation analysis results, the final arrangement position of the vehicle noise warning system is determined. Therefore, this application can analyze the vehicle interior noise information and vehicle exterior noise information collected at each initial arrangement position to determine the final arrangement position of the vehicle noise warning system. This solves the problem of noise generated by the vehicle emitting a low-speed warning sound when the vehicle is traveling at low speed, thus reducing the user's driving experience. Furthermore, since the noise characteristics inside the vehicle and the noise transmission loss outside the vehicle are considered when determining the final arrangement position of the vehicle noise warning system, installing the vehicle noise warning system at the final arrangement position can reduce vehicle interior noise and improve the user's driving experience.
