[0038] Figure 2 is a schematic structural diagram of the horn volume adjustment device for a vehicle in the embodiments of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] See Figure 1 , in the first aspect of the embodiments of the present invention, a horn volume adjustment method for a vehicle is provided, including the following steps S1 to S4:

[0041] Step S1: Detect the orientations of all pedestrians and vehicles within a preset range, and based on the orientation of each pedestrian and the orientation of each vehicle, obtain the first distance from each pedestrian and the second distance from each vehicle;

[0042] Step S2: Based on the first distance, determine the pedestrian decibel attenuation value corresponding to each pedestrian, and according to the pedestrian decibel attenuation value and the preset minimum pedestrian warning decibel value, determine the pedestrian warning target decibel value;

[0043] Step S3: Based on the second distance, determine the driving decibel attenuation value corresponding to each vehicle, and determine the driving warning target decibel value according to the driving decibel attenuation value, the vehicle type of each vehicle, and the preset minimum driving warning decibel value.

[0044] Step S4: Determine the target warning decibel value based on the comparison result between the pedestrian warning target decibel value and the driving warning target decibel value, and adjust the horn volume according to the target warning decibel value.

[0045] Specifically, in this embodiment, cameras configured around the vehicle body detect the orientations of all pedestrians and vehicles within a preset range. Preferably, the preset range is a circular range with a radius of 30 meters. Based on the orientations of each pedestrian and each vehicle, the first distance between the vehicle and each pedestrian and the second distance between the vehicle and each vehicle are obtained.

[0046] Since the sound will attenuate when propagating in the air, in this embodiment, based on the first distance between the vehicle and each pedestrian, the pedestrian decibel attenuation value corresponding to each pedestrian is determined. Further, according to the pedestrian decibel attenuation value and the preset minimum pedestrian warning decibel value, the pedestrian warning target decibel value is determined. It can be understood that the minimum pedestrian warning decibel value is the decibel value that can just wake up pedestrians.

[0047] Based on the second distance, determine the driving decibel attenuation value corresponding to each vehicle, and determine the driving warning target decibel value according to the driving decibel attenuation value, the vehicle type of each vehicle, and the preset minimum driving warning decibel value. It can be understood that different vehicle types have different sound blocking effects. Therefore, in this embodiment, the vehicle type of the vehicle needs to be considered when determining the driving warning target decibel value; the minimum driving warning decibel value is the decibel value that can just wake up the driver.

[0048] Further, according to the comparison result between the pedestrian warning target decibel value and the driving warning target decibel value, the maximum value between the two is used as the target warning decibel value. It can be understood that in order to enable all vehicles and pedestrians within the preset range to receive the wake-up sound, the maximum value between the pedestrian warning target decibel value and the driving warning target decibel value needs to be taken as the decibel value for adjusting the horn volume.

[0049] A method for adjusting the horn volume of a vehicle provided by an embodiment of the present invention can respectively determine the pedestrian warning target decibel value and the driving warning target decibel value based on the distance between the vehicle and surrounding pedestrians, the distance between the vehicle and surrounding vehicles, and the vehicle types of surrounding vehicles, and adjust the horn volume according to the comparison result between the two, which can take both pedestrians and vehicles around the vehicle into account and ensure the wake-up effect on surrounding vehicles while adjusting the horn volume of the vehicle.

[0050] As a preferred solution, determining the pedestrian decibel attenuation value corresponding to each pedestrian based on the first distance specifically includes the following steps:

[0051] Based on the first distance, determine the pedestrian decibel attenuation value corresponding to each pedestrian through the following expression:

[0052]

[0053] Wherein, represents the pedestrian decibel attenuation value, represents the first distance, is a parameter with a value of 1.

[0054] As a preferred solution, determining the pedestrian warning target decibel value according to the pedestrian decibel attenuation value and the preset minimum pedestrian warning decibel value specifically includes the following steps:

[0055] Determine the warning decibel value corresponding to each pedestrian according to the minimum pedestrian warning decibel value and the pedestrian decibel attenuation value corresponding to each pedestrian;

[0056] Compare the warning decibel values corresponding to each pedestrian, and use the maximum warning decibel value as the pedestrian warning target decibel value.

[0057] It should be noted that comparing the warning decibel values corresponding to each pedestrian and using the maximum warning decibel value as the pedestrian warning target decibel value is aimed at enabling all pedestrians within the preset range to receive the warning sound.

[0058] As a preferred solution, determining the vehicle decibel attenuation value corresponding to each vehicle based on the second distance specifically includes the following steps:

[0059] Based on the second distance, determine the vehicle decibel attenuation value corresponding to each vehicle through the following expression:

[0060]

[0061] Wherein, represents the vehicle decibel attenuation value, represents the second distance, is a parameter with a value of 1.

[0062] As a preferred solution, determining the vehicle warning target decibel value according to the vehicle decibel attenuation value, the vehicle type of each vehicle, and the preset minimum vehicle warning decibel value specifically includes the following steps:

[0063] If the vehicle type of the current driving vehicle is an enclosed vehicle, then according to the driving decibel attenuation value corresponding to the current driving, the preset sound insulation decibel value, and the minimum driving warning decibel value, determine the warning decibel value corresponding to the current driving;

[0064] If the vehicle type of the current driving vehicle is a non-enclosed vehicle, then according to the driving decibel attenuation value corresponding to the current driving and the minimum driving warning decibel value, determine the warning decibel value corresponding to the current driving;

[0065] Compare the warning decibel values corresponding to each driving vehicle, and take the largest warning decibel value as the target driving warning decibel value.

[0066] It should be noted that an enclosed vehicle is a vehicle in which the passengers inside the vehicle are fully enclosed, such as a vehicle with the windows not opened. A non-enclosed vehicle is a vehicle in which the passengers inside the vehicle are not fully enclosed, such as a vehicle with the windows opened and a convertible, etc.

[0067] If the vehicle type of the current driving vehicle is a non-enclosed vehicle, the sound insulation effect of the vehicle material needs to be considered. Usually, the sound insulation range is between 3 decibels and 15 decibels. Therefore, in this embodiment, according to the driving decibel attenuation value corresponding to the current driving, the preset sound insulation decibel value, and the minimum driving warning decibel value, determine the warning decibel value corresponding to the current driving.

[0068] If the vehicle type of the current driving vehicle is a non-enclosed vehicle, the passengers inside the vehicle are not affected by the sound insulation effect of the vehicle material, and it can be handled in a similar situation to pedestrians. Therefore, in this embodiment, according to the driving decibel attenuation value corresponding to the current driving and the minimum driving warning decibel value, determine the warning decibel value corresponding to the current driving.

[0069] Furthermore, compare the warning decibel values corresponding to each driving vehicle, and take the largest warning decibel value as the target driving warning decibel value. The purpose is to enable all passengers inside the vehicles within the preset range to receive the warning sound.

[0070] As a preferred solution, obtaining the first distance between each pedestrian and the second distance between each driving vehicle based on the azimuth of each pedestrian and the azimuth of each driving vehicle specifically includes the following steps:

[0071] Based on the azimuth of each pedestrian and the azimuth of each driving vehicle, emit infrared rays to each pedestrian and each driving vehicle respectively;

[0072] According to the time between emitting infrared rays and receiving the reflected infrared rays, obtain the first distance and the second distance.

[0073] It can be understood that cameras configured around the vehicle body can obtain the approximate positions of pedestrians and vehicles around the vehicle. Based on the approximate positions of pedestrians and vehicles, infrared rays are respectively emitted to each pedestrian and each vehicle. When the infrared rays are reflected back from the pedestrians or vehicles, the first distance and the second distance can be obtained according to the time between emitting the infrared rays and receiving the reflected infrared rays.

[0074] As a preferred solution, the minimum decibel value of the pedestrian warning is equal to the minimum decibel value of the vehicle warning.

[0075] It should be noted that since both pedestrians and passengers in vehicles are human bodies, the minimum decibel values of the warnings for both are two identical values.

[0076] As an optional embodiment, both the minimum decibel value of the pedestrian warning and the minimum decibel value of the vehicle warning are 55 decibels. It should be noted that the most suitable sound decibel for the human body to receive is below 44 decibels. When the sound decibel is 44 - 55 decibels, people will feel upset. When the sound decibel is 55 - 70 decibels, they will have no sleepiness. When the sound decibel is above 70 decibels, people will be nervous. Based on this, assuming that when the human body hears a sound of 55 decibels, it can have a waking effect, so the most suitable volume decibel of the vehicle horn reaching the human body is 55 decibels. Larger than 55 decibels will cause more urban noise pollution, and smaller than 55 decibels will weaken the waking effect.

[0077] Exemplarily, assume that a vehicle A wants to overtake and needs to wake up the pedestrians and the driver in the vehicle around it. At this time, vehicle A detects through the camera and infrared rays that there is a pedestrian B at 10 meters and a vehicle C at 10 meters, and vehicle C is an enclosed vehicle. Both pedestrian B and vehicle C need to receive the optimal horn sound reminder, that is, the decibel value is 55 decibels. Then according to the formula , the decibel attenuation value of pedestrian B can be calculated as 20 decibels. Then, a horn sound of 75 decibels is required to wake up pedestrian B. According to the formula , the decibel attenuation value of vehicle C can also be calculated as 20 decibels. And taking the sound insulation decibel value of the vehicle material as 15 decibels, a horn sound of 90 decibels is required to wake up vehicle C. Comparing 90 decibels and 75 decibels, the maximum value of 90 decibels is taken as the final sound decibel number of the horn.
