[0002] When a vehicle is traveling in traffic jams or on highways, external noise can affect the communication environment inside the vehicle.

[0022] Figure 3 This is a schematic diagram of the structure of a noise control device inside a vehicle provided in an embodiment of this application. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] This application provides a method for controlling noise inside a vehicle. Please refer to [the relevant documentation]. Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: an IHU (Infotainment Head Unit) 11, a BCM (Body Control Module) 12, a voice assistant 13, a steering wheel 14, a vehicle central control screen 15, an ABS (Anti-lock Braking System) 16, a sound sensor 17, multimedia equipment 18, and windows 19.

[0025] Optionally, if the voice assistant 13 receives a command to activate the automatic volume control function, the corresponding switch for the automatic volume control function on the steering wheel 14 is turned on, or the vehicle's central control screen 15 receives a command to activate the automatic volume control function, the IHU 11 controls the automatic volume control function to be activated. The IHU 11 detects the frequencies of various sounds inside the vehicle using the sound sensor 17. If the frequency of at least one sound inside the vehicle is within the range of human voice frequencies, it indicates that someone is speaking inside the vehicle.

[0026] In response to the presence of people speaking inside the vehicle, the IHU 11 detects the intensity of the speech through the sound sensor 17, and then determines the noise control level inside the vehicle based on the intensity of the speech. The IHU 11 controls at least one of the following according to the noise control level inside the vehicle: the volume percentage of the multimedia 18 and the opening / closing status of the windows 19.

[0027] In one possible implementation, if the vehicle interior noise control level is Level 1, the IHU 11 reads the volume percentage of the multimedia 18 from the BCM 12. If the volume percentage of the multimedia 18 is greater than a first volume threshold, the volume percentage of the multimedia 18 is reduced to the first volume threshold. The vehicle's central control screen 15 then notifies the occupants that the multimedia volume has been reduced to the first volume threshold, facilitating communication. If the vehicle interior noise control level is Level 2, the IHU 11 reads the vehicle's speed from the ABS 16 and the volume percentage of the multimedia 18 and the open / closed status of the windows 19 from the BCM 12. If the vehicle speed is greater than a speed threshold and the volume percentage of the multimedia 18 is greater than a second volume threshold, the volume percentage of the multimedia 18 is reduced to the second volume threshold. The vehicle's central control screen 15 then notifies the occupants that the multimedia volume has been reduced to the second volume threshold, facilitating communication. If the vehicle's speed exceeds a speed threshold and at least one window 19 is not closed, the window 19 will be closed. The vehicle's central control screen 15 will then notify the occupants that all windows are closed to prevent them from being disturbed by external noise while speaking.

[0028] Optionally, after reducing the volume percentage of at least one multimedia device 18, in response to a first sound intensity being less than or equal to a second intensity threshold, the volume percentage of multimedia device 18 is restored to a third volume threshold. If the voice assistant 13 receives a command to turn off the automatic volume control function, the switch corresponding to the automatic volume control function on the steering wheel 14 is turned off, or the vehicle central control screen 15 receives a command to turn off the automatic volume control function, the IHU 11 controls the automatic volume control function to turn off.

[0029] Among them, IHU11, BCM12, voice assistant 13, steering wheel 14, vehicle central control screen 15, ABS 16, sound sensor 17, multimedia 18 and windows 19 establish communication connections through wired or wireless networks.

[0030] Based on the above Figure 1 The implementation environment shown in this application provides a method for controlling noise inside a vehicle. Figure 2 As shown, taking the application of this method to IHU as an example, the method includes steps 201-204.

[0031] In step 201, in response to the activation of the automatic volume control function inside the vehicle, a first detection result is obtained, which is used to indicate whether there are people talking inside the vehicle.

[0032] In one possible implementation, occupants of the vehicle can activate the automatic volume control function by issuing a command to the vehicle's voice assistant, turning on the corresponding switch for the automatic volume control function on the vehicle's steering wheel, or selecting the automatic volume control function on the vehicle's central control screen.

[0033] For example, in response to at least one of the following: the vehicle's voice assistant receiving an instruction to enable the automatic volume control function, the automatic volume control function switch on the steering wheel being turned on, or the vehicle's central control screen receiving an instruction to enable the automatic volume control function, the automatic volume control function is enabled.

[0034] Optionally, the IHU can obtain detection results from the vehicle's voice assistant via the bus, indicating whether the voice assistant has received a command to activate the automatic volume control function. The IHU can also obtain detection results from the steering wheel via the bus, indicating whether the switch corresponding to the automatic volume control function on the steering wheel is turned on. Furthermore, the IHU can obtain detection results from the vehicle's central control screen via the bus, indicating that the central control screen has received a command to activate the automatic volume control function. If at least one of the following conditions is met: the vehicle's voice assistant has received a command to activate the automatic volume control function, the switch corresponding to the automatic volume control function on the steering wheel is turned on, or the central control screen has received a command to activate the automatic volume control function, the IHU activates the automatic volume control function. Optionally, the bus can be a CAN (Controller Area Network) bus.

[0035] For example, in response to the activation of an automatic volume control function inside the vehicle, a first detection result is obtained, wherein the first detection result is used to indicate whether there is a person talking inside the vehicle. Obtaining the first detection result includes: detecting a second sound intensity, the second sound intensity indicating the total intensity of various sounds inside the vehicle; in response to the second sound intensity being greater than a first intensity threshold, detecting the frequencies of various sounds inside the vehicle; and in response to the frequency of at least one sound inside the vehicle being within the human voice frequency range, indicating that the first detection result indicates that there is a person talking inside the vehicle.

[0036] In one possible implementation, a sound sensor installed in the vehicle measures the total intensity of various sounds inside the vehicle, and uses this total intensity as a second sound intensity. The second sound intensity is compared to a first intensity threshold. If the second sound intensity is greater than the first intensity threshold, it indicates that at least one of the following conditions is met: the volume of the multimedia system inside the vehicle is turned on; someone is talking inside the vehicle; or noise from outside the vehicle is affecting the interior. The sound sensor then detects the frequencies of various sounds inside the vehicle. After detecting the frequencies, these frequencies are compared to the range of human voice frequencies. If at least one sound frequency inside the vehicle falls within the human voice frequency range, the first detection result indicates that someone is talking inside the vehicle. If none of the sound frequencies inside the vehicle fall within the human voice frequency range, the first detection result indicates that no one is talking inside the vehicle, and the sound originates from the multimedia system or noise from outside the vehicle.

[0037] If the second sound intensity is less than or equal to the first intensity threshold, it indicates that the multimedia volume percentage inside the vehicle is not turned on, no one is talking inside the vehicle, or external noise is not affecting the interior of the vehicle. The first detection result then indicates that no one is talking inside the vehicle. The sound sensor is installed inside the vehicle and can detect the intensity, frequency, and rhythm of the sound. Optionally, the first intensity threshold can be set empirically. The frequency range containing the human voice can be defined as the human voice frequency range.

[0038] Because multimedia audio has a wide frequency range, and the frequency of spoken voices is within a certain frequency range, the frequency range of human voices can be used to distinguish between spoken and non-spoken voices, making it easier to select the most suitable method to reduce noise interference based on the intensity of the spoken voice.

[0039] In step 202, in response to a first detection result indicating that someone is speaking inside the vehicle, a first sound intensity is detected, the first sound intensity indicating the intensity of the speaking sound.

[0040] For example, after determining a first detection result, in response to the first detection result indicating that a person is speaking inside the vehicle, a first sound intensity is detected, wherein the first sound intensity indicates the intensity of the speaking sound. Detecting the first sound intensity includes: determining that the sound inside the vehicle with a frequency within the human voice frequency range is the sound of a person speaking inside the vehicle, detecting the intensity of the sound of a person speaking inside the vehicle using a sound sensor installed on the vehicle, and using the intensity of the sound of a person speaking inside the vehicle as the first sound intensity.

[0041] By detecting the volume of voices spoken by people inside the vehicle, it is possible to select the most suitable method to reduce noise interference based on the communication needs of the people inside the vehicle, thus providing a suitable communication environment for them.

[0042] In step 203, the noise control level inside the vehicle is determined based on the first sound intensity.

[0043] Optionally, after determining the first sound intensity, in response to the first sound intensity being greater than a second intensity threshold and less than or equal to a third intensity threshold, the noise control level inside the vehicle is determined to be a first level, wherein the third intensity threshold is greater than the second intensity threshold; in response to the first sound intensity being greater than the third intensity threshold, the noise control level inside the vehicle is determined to be a second level, wherein the noise control level corresponding to the second level is greater than the noise control level corresponding to the first level.

[0044] In one possible implementation, a first sound intensity is compared with a second intensity threshold and a third intensity threshold. If the first sound intensity is greater than the second intensity threshold and less than or equal to the third intensity threshold, it indicates that the first sound intensity is low, possibly indicating that someone in the vehicle is making a phone call or one of the occupants is speaking. In this case, the noise control level inside the vehicle is set to level one. If the first sound intensity is greater than the third intensity threshold, it indicates that the first sound intensity is high, possibly indicating that someone in the vehicle is conversing with each other. In this case, the noise control level inside the vehicle is set to level two.

[0045] Optionally, the first and third intensity thresholds can be set according to requirements, ensuring that the third intensity threshold is greater than the second intensity threshold. For example, the second intensity threshold can be set to 40 dB and the third intensity threshold can be set to 60 dB.

[0046] By setting the noise control level inside the vehicle, it is easier to control the multimedia and windows inside the vehicle according to different noise control levels, thereby providing a suitable environment for communication between the people inside the vehicle.

[0047] In step 204, at least one of the following is controlled based on the noise control level inside the vehicle: the volume percentage of the multimedia inside the vehicle and the opening / closing status of the windows. The volume percentage of the multimedia is the percentage of the current volume of the multimedia relative to the highest volume of the multimedia.

[0048] For example, after determining the noise control level inside the vehicle, controlling at least one of the following based on the noise control level inside the vehicle: the volume percentage of the multimedia system inside the vehicle and the opening / closing state of the windows, includes: reading the volume percentage of the multimedia system inside the vehicle in response to the noise control level inside the vehicle being a first level; and reducing the volume percentage of the multimedia system inside the vehicle to the first volume threshold in response to the multimedia system volume percentage being greater than a first volume threshold. Here, the multimedia volume percentage is the percentage of the current volume of the multimedia system relative to its highest possible volume.

[0049] Optionally, if the vehicle's interior noise control level is set to Level 1, the IHU reads the volume of each multimedia device inside the vehicle from the BCM via the CAN bus. These multimedia devices can be the vehicle's audio system, navigation system, and voice assistant. The volume of each multimedia device is compared to a first volume threshold. If the volume of any multimedia device exceeds the first volume threshold, the IHU controls the BCM to reduce its volume to the first volume threshold. Once the multimedia volume is reduced, a notification is displayed on the vehicle's central control screen indicating that the volume has been lowered to the first volume threshold, facilitating communication among the occupants. Optionally, the notification message can be displayed as text on the vehicle's central control screen.

[0050] If the volume of each multimedia component does not exceed a first volume threshold, the volume of the multimedia component will not be adjusted. For example, the first volume threshold can be set as needed, and different multimedia components can correspond to different first volume thresholds. For instance, the IHU can set the first volume threshold to 20% of the maximum volume of the multimedia component. Based on receiving an instruction to set the first volume threshold of any multimedia component, the IHU sets the first volume threshold, and the first volume threshold remains unchanged until the next modification.

[0051] In one possible implementation, in response to the ECU (Electronic Control Unit) sending vehicle warning information to the voice assistant, and for the sake of vehicle driving safety, to ensure that occupants inside the vehicle can hear the warning information, the voice assistant's volume is controlled to increase to a predetermined volume, or to increase to a preset value higher than the current second sound intensity. Optionally, the preset value can be determined based on the correspondence between the second sound intensity and the preset value, and the predetermined volume can be set as needed. The ECU is located in the vehicle and can collect data on any abnormalities occurring in the vehicle. Optionally, the warning information includes, but is not limited to: warnings of vehicle speeding, warnings of impending vehicle battery depletion, and warnings of other vehicle abnormalities.

[0052] Optionally, in response to the vehicle interior noise control level being the second level, the vehicle's driving speed, the volume percentage of the vehicle's multimedia system, and the open / closed state of the windows are read; in response to the vehicle's driving speed being greater than a speed threshold and the volume percentage of the vehicle's multimedia system being greater than a second volume threshold, the volume percentage of the vehicle's multimedia system is reduced to the second volume threshold; in response to the vehicle's driving speed being greater than a speed threshold and at least one window being open / closed, the window opening / closing state is controlled so that all windows are closed.

[0053] In one possible implementation, if the vehicle's interior noise control level is Level 2, the IHU reads the vehicle's speed from the ABS via the CAN bus, and reads the volume of each multimedia system and the opening / closing status of each window from the BCM via the CAN bus. The vehicle's speed is compared to a speed threshold, and the volume of each multimedia system is compared to a second volume threshold. If the vehicle's speed exceeds the speed threshold and the volume percentage of the multimedia system exceeds the second volume threshold, the IHU controls the BCM to reduce the volume of that multimedia system to the second volume threshold. Once the multimedia volume is reduced, the vehicle's central control screen notifies the occupants that the volume has been lowered to the second volume threshold, facilitating communication within the vehicle.

[0054] For example, if the vehicle's speed exceeds a speed threshold and at least one window is not closed, the IHU controls the BCM to close all the open windows. Once all windows are closed, the vehicle's central control screen will notify the occupants that all windows have been closed, preventing them from being disturbed by external noise while talking.

[0055] In one possible implementation, if the volume of each multimedia component does not exceed a second volume threshold, the volume of the multimedia component is not adjusted. For example, the second volume threshold can be set as needed, and different multimedia components can correspond to different second volume thresholds. For instance, the IHU can set the second volume threshold to five percent of the maximum volume of the multimedia component. Based on receiving an instruction to set the second volume threshold for any multimedia component, the IHU sets the second volume threshold, and the second volume threshold remains unchanged until the next modification.

[0056] Optionally, the control of multimedia volume percentage and window opening / closing status based on the vehicle's interior noise level takes lower priority than manual control of multimedia volume percentage and window opening / closing status by occupants. For example, if at least one of the multimedia volume or window opening / closing status is controlled via the BCM, and then occupants manually adjust either the multimedia volume or the window opening / closing status, the result of the manual adjustment is maintained for a preset duration to avoid interfering with the normal needs of the occupants. This preset duration can be set as needed.

[0057] In one possible implementation, after reducing the volume percentage of at least one multimedia device inside the vehicle, in response to a first sound intensity being less than or equal to a second intensity threshold, restoring the volume percentage of the multimedia device inside the vehicle to a third volume threshold includes: if the first sound intensity, after the volume percentage of at least one multimedia device inside the vehicle is reduced, decreases to less than or equal to the second intensity threshold, the IHU controls the volume percentage of that multimedia device to be restored to the third volume threshold via the BCM. Optionally, the third volume threshold can be set as needed, and different multimedia devices can correspond to different third volume thresholds. For example, the IHU can set the third volume threshold to 40% of the maximum volume of the multimedia device. Based on receiving an instruction to set the third volume threshold of any multimedia device, the IHU sets the third volume threshold, and the third volume threshold remains unchanged until the next modification.

[0058] In one possible implementation, occupants of the vehicle can enable the automatic volume control function by issuing a command to the vehicle's voice assistant to turn off the automatic volume control function, by turning off the corresponding switch on the vehicle's steering wheel, or by selecting to turn off the automatic volume control function on the vehicle's central control screen.

[0059] For example, in response to at least one of the following: the vehicle's voice assistant receiving an instruction to turn off the automatic volume control function, the automatic volume control function switch on the steering wheel being turned off, or the vehicle's central control screen receiving an instruction to turn off the automatic volume control function, the automatic volume control function is turned off.

[0060] Optionally, the IHU can obtain detection results from the vehicle's voice assistant via the bus, indicating whether the voice assistant has received a command to turn off the automatic volume control function. The IHU can also obtain detection results from the steering wheel via the bus, indicating whether the switch corresponding to the automatic volume control function on the steering wheel is turned off. Furthermore, the IHU can obtain detection results from the vehicle's central control screen via the bus, indicating that the central control screen has received a command to turn off the automatic volume control function. If at least one of the following conditions is met: the vehicle's voice assistant has received a command to turn off the automatic volume control function, the switch corresponding to the automatic volume control function on the steering wheel is turned off, or the central control screen has received a command to turn off the automatic volume control function, the IHU controls the automatic volume control function to turn off.

[0061] In one possible implementation, the intensity, rhythm, and frequency characteristics of the spoken voice are analyzed; the intensity, rhythm, and frequency characteristics of the multimedia sound are analyzed; in response to the similarity between the intensity characteristics of the spoken voice and the intensity characteristics of at least one multimedia sound being greater than a similarity threshold, the similarity between the rhythm characteristics of the spoken voice and the rhythm characteristics of at least one multimedia sound being greater than a similarity threshold, and the similarity between the frequency characteristics of the spoken voice and the frequency characteristics of at least one multimedia sound being greater than a similarity threshold, the function of automatically controlling the volume is turned off.

[0062] For example, the intensity, rhythm, and frequency features of speech can be extracted from the speech inside the vehicle using a speech recognition algorithm, and the intensity, rhythm, and frequency features of multimedia sound can be extracted from multimedia sound.

[0063] When the similarity between the intensity, rhythm, and frequency characteristics of spoken voice and those of multimedia voice reaches a similarity threshold, the automatic volume control function is turned off to prevent the multimedia volume from being reduced and affecting the passenger experience when people inside the vehicle sing along with the multimedia.

[0064] In this embodiment, after activating the automatic volume control function, it determines whether anyone is speaking inside the vehicle. If someone is speaking, it detects the first sound intensity of the speech, which is then used to select the most suitable noise control method for the current vehicle interior environment. After determining the first sound intensity, it determines the noise control level inside the vehicle. Then, based on the control level, it controls at least one of the following: the volume percentage of the multimedia system inside the vehicle and the open / closed state of the windows. This achieves the selection of the most suitable method to reduce noise interference and provides a suitable environment for communication between people inside the vehicle or for people inside the vehicle to communicate by phone.
