[0043] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] As mentioned in the background section, this application proposes a vehicle audio control method to address the problems in the prior art. This method is applicable to situations where multiple vehicle audio systems are installed in a vehicle, and the control method changes when the occupants' information changes. The control is executed by electronic equipment, such as... Figure 1 As shown, the method includes the following steps:

[0046] S101. Determine the information of the people in the vehicle based on the user data obtained from the vehicle camera and seat sensors;

[0047] S102. Based on the information of the people inside the vehicle and the configuration of the vehicle audio system, determine the control information of the vehicle audio system;

[0048] S103. Control the vehicle audio system according to the control information of the vehicle audio system;

[0049] The information about the people inside the vehicle includes: the number of users, user locations, and user postures.

[0050] In this embodiment, firstly, based on user data acquired by the vehicle-mounted camera and seat sensors, the information of the occupants in the vehicle is determined. Then, based on the occupant information and the configuration of the vehicle audio system, the control information for the vehicle audio system is determined. Finally, the vehicle audio system is controlled according to the control information. The occupant information includes the number of users, their positions, and their postures. Since the control information for the vehicle audio system can be determined based on the occupant information and the configuration of the vehicle audio system, manual control is unnecessary, thus saving manual operation steps and improving the user experience.

[0051] In practice, user data can include images or videos captured by in-vehicle cameras and weight information obtained from seat sensors. The user's posture inside the vehicle can be determined by analyzing the images or videos captured by the in-vehicle cameras, for example, through posture analysis. Similarly, the user's location and number can be determined by analyzing the weight information obtained from the seat sensors. For instance, if the weight information obtained by the seat sensor on the front passenger seat is 50kg, then it is determined that there is a user in the front passenger seat, and the front passenger seat is taken as the user location, and the user number is counted as 1.

[0052] In this application, the user posture refers to the user's current posture, such as sleeping, sitting at an angle, sitting upright, or lying flat. Specifically, the user posture can be obtained through information collected by a camera or through seat sensors. For example, by analyzing images or videos collected by the camera and identifying features, the user posture can be obtained. Alternatively, the angle of the seat can be obtained through the seat sensors, and the user posture can be determined based on the obtained seat angle. For example, if the seat angle is 120 degrees, the user posture is determined to be sitting at an angle; if the seat angle is 175 degrees, the user posture is determined to be taking a nap.

[0053] After obtaining the number of users, their locations, and their postures inside the vehicle, the control information for the vehicle audio system is determined based on the information about the people inside the vehicle and the configuration of the vehicle audio system. Specifically, the target location representing the sound effect center can be determined first based on the user location and the configuration of the vehicle audio system. Then, the control information for the vehicle audio system is determined based on the number of users, the target location, the user posture, and the corresponding relationship. The corresponding relationship is the relationship between the number of users, the target location, the user posture, and the control information for the vehicle audio system.

[0054] It should be noted that the target location in this application is the location that represents the center of the sound effect, that is, the location where the user hears the best sound effect.

[0055] The correspondence in this application is a preset correspondence. For example, the number of users is 1, the target location is the driver's seat, the user posture is sitting upright, and the control information of the car audio system is to control the operation of the car audio system above the driver's seat.

[0056] In one embodiment, determining the target location based on the user's location and the configuration of the vehicle audio system can include the following three scenarios:

[0057] Scenario 1: If the car audio system is the first configuration, then each user's location will be the target location.

[0058] Specifically, first determine the center point of each user's location, and then for each user's location, use the center point of the user's location as the target location.

[0059] Scenario 2: If the car audio system is configured as the second configuration, and the in-vehicle occupant information includes multiple user locations, then the center point of the multiple user locations will be used as the target location.

[0060] Specifically, the center point of multiple user locations is determined in the following way:

[0061] First, determine the center point of each user's location, and then use the points that are equidistant from the center point of each user's location as the center points of multiple user locations.

[0062] Scenario 3: If the car audio system is configured as the second configuration and includes a user location, then the user location will be used as the target location.

[0063] Specifically, the center point of the user's location is first determined, and then the center point of the user's location is used as the target location.

[0064] The vehicle's audio system is configured in two ways: a first configuration and a second configuration. The first configuration has a first preset number of speakers, and the second configuration has a second preset number of speakers. The first preset number is greater than the second preset number, meaning the first configuration has more speakers than the second configuration, and the amplifier capacity of the first configuration is greater than that of the second configuration. In practice, the first and second configurations of the audio system are distributed differently within the vehicle. For example, the first configuration has 10 speakers, distributed as follows: above and to the left of the driver's seat; above and to the right of the passenger seat; above and to the right of the passenger seat; and two speakers above and to the rear of the rear seats. The second configuration has 7 speakers, distributed as follows: above and to the left of the driver's seat; above and to the right of the passenger seat; and one speaker above and to the left of the rear seats.

[0065] It should be noted that the number of speakers for the first and second configurations of the car audio system mentioned above are just examples.

[0066] In this embodiment of the application, if the vehicle audio system is the first configuration, that is, if there are a large number of vehicle audio systems, then each user position is taken as the target position. For example, if the vehicle audio system is the first configuration and the user positions are the driver's seat and the rear seat, then both the driver's seat and the rear seat are taken as target positions.

[0067] If the car audio system is a secondary configuration, meaning there are fewer car audio systems, and the occupant information includes multiple user locations, then the center point of these multiple user locations will be used as the target location. For example, if the car audio system is a secondary configuration and includes the driver's seat and the rear seat, then the center point of the driver's seat and the rear seat will be used as the target location.

[0068] If the car audio system is a second configuration and includes a user position, then that user position is used as the target position. For example, if the car audio system is a second configuration and includes a driver's position, then the driver's position is used as the target position.

[0069] like Figure 2 and Figure 3 The images shown are all target locations determined when the car audio system is the second configuration.

[0070] like Figure 2 As shown, the user's positions are the driver's seat and the rear seat position 1. Based on the center point A of the driver's seat and the center point B of the rear seat position 1, the midpoint a of the distance between the center point A and the center point B is determined, and a is taken as the target position.

[0071] like Figure 3 As shown, the user positions are the driver's seat, rear seat 1, and rear seat 2. The center point of the driver's seat is A, the center point of rear seat 1 is B, and the center point of rear seat 2 is C. The point b, which is equidistant from the center points A, B, and C, is taken as the target position.

[0072] In practice, a coordinate system can be established by first taking the center point of the rear seat position 1 in the vehicle as the origin, then determining the coordinates of the center point of each position, and finally determining the coordinates of the target position based on the coordinates of the user's position.

[0073] If the car audio system is the primary configuration, each user's location can be used as the target location, meaning the center point of the user's location can be used as the target location.

[0074] In one embodiment, after determining the target location, the control information of the vehicle audio system is determined based on the number of users, the target location, the user posture, and the corresponding relationship. The corresponding relationship can be displayed in the form of a curve or a chart. After determining the number of users, the target location, and the user posture, the control information of the vehicle audio system is retrieved from the corresponding relationship.

[0075] The control information for the vehicle audio system in this application can include controlling whether the vehicle audio system is turned on or off, and the output power of the turned-on vehicle audio system.

[0076] In one embodiment, after controlling the vehicle audio system according to the vehicle audio control information, after determining that the change in the vehicle occupant information reaches a preset condition, the vehicle occupant information is re-determined, and then the vehicle audio switching information is determined based on the re-determined occupant information and the vehicle audio system configuration. Finally, the vehicle audio system is controlled according to the vehicle audio switching information.

[0077] In this embodiment of the application, if the information of the people in the car changes during the operation of the car audio system, the operating status of the car audio system can be adjusted based on the amount of change in the information of the people in the car. For example, if the people in the back seat of the car move from the back seat position 1 to the back seat position 2, and it is determined that the amount of change in the information of the people in the car has reached the preset condition, it is necessary to re-determine the information of the people in the car. Based on the re-determined information of the people and the configuration of the car audio system, the car audio system is controlled.

[0078] Specifically, the changes in the number of people inside the vehicle can be determined based on the changes in each location and the changes in the information collected by the cameras. For example, the change in the number of people in the driver's seat can be determined by Δ. 用户数量 The angle Δ of the driver's seat 座椅角度 The change in the number of people in the co-pilot's seat is determined by the change in Δ. 用户数量 The change in seat angle Δ at the passenger seat position 座椅角度 Determine the change in the number of people in the back seat, Δ 用户数量 The change in seat angle Δ at the rear seat position 座椅角度 Determine the change Δ in the features of the content management system (CMS) based on the images or videos captured by the camera. CMS Switching condition I is:

[0079] I=(Δ 用户数量 +Δ 座椅角度 ) 主 +(Δ 用户数量 +Δ 座椅角度 ) 副 +(Δ 用户数量 +Δ 座椅角度 ) 后座 +

[0080] Δ CMS ;

[0081] Among them, (Δ 用户数量 +Δ 座椅角度 ) 主 This represents the sum of the change in the number of people in the driver's seat and the change in seat angle, (Δ) 用户数量 +Δ 座椅角度 ) 副 This represents the sum of the change in the number of people in the front passenger seat and the change in seat angle, (Δ) 用户数量 +Δ 座椅角度 ) 后座 Δ represents the sum of the change in the number of people in the rear seats and the change in seat angle; CMS This represents the change in posture, specifically the difference between the current CMS-identified feature value and the previous CMS-identified feature value.

[0082] In practice, after obtaining the previously measured number of users and seat angles, as well as the currently measured number of users and seat angles, the number of users and seat angles are first converted. Specifically, the conversion is performed according to a preset correspondence. For example, the value corresponding to the number of users is a1, the value corresponding to the number of users is b1, the value corresponding to the number of users is c1, and so on. The value corresponding to a seat angle of 90 degrees is a2, the value corresponding to a seat angle of 110 degrees is b2, the value corresponding to a seat angle of 140 degrees is c2, and so on. Both the previously obtained CMS value and the currently obtained CMS value are values ​​obtained by feature recognition of the acquired images or videos, used to represent the user's posture. For example, if feature recognition determines that two people are lying flat, the value obtained is a3.

[0083] For example, the data from the previous measurement was as follows: 0 people in the driver's seat, seat angle 90 degrees; 0 people in the front passenger seat, seat angle 90 degrees; 0 people in the rear driver's seat, seat angle 90 degrees; CMS value a3. The data from the current measurement is as follows: 1 person in the driver's seat, seat angle 110 degrees; 0 people in the front passenger seat, seat angle 90 degrees; 0 people in the rear driver's seat, seat angle 90 degrees; CMS value b3. After converting the number of users and seat angles according to the corresponding relationships, the following calculations are performed:

[0084] I=(Δ 用户数量 +Δ 座椅角度 ) 主 +(Δ 用户数量 +Δ 座椅角度 ) 副 +(Δ 用户数量 +Δ 座椅角度 ) 后座 +

[0085] Δ CMS =((b1-a1)+(b2-a2)) 主 +(0+0) 副 +(0+0) 后座 +(b3-a3).

[0086] In this application, an I value is preset. When the calculated value is greater than the preset I value, it is determined that the change in the information of the people in the vehicle has reached the preset condition. At this time, the information of the people in the vehicle is re-determined based on the user data obtained by the vehicle camera and seat sensor. Then, based on the re-determined information of the people and the configuration of the vehicle audio system, the switching information of the vehicle audio system is determined. Here, the switching information of the vehicle audio system is determined based on the re-determined information of the people and the configuration of the vehicle audio system. This can be referred to in the above embodiment, where the control information of the vehicle audio system is determined based on the information of the people in the vehicle and the configuration of the vehicle audio system. It will not be repeated here.

[0087] Once the switching information is determined, the car audio system is controlled accordingly. For example, if the currently active car audio systems are Car Audio 1, Car Audio 2, and Car Audio 3, and the determined switching information is to turn on Car Audio 3 and Car Audio 4, then Car Audio 4 is turned on, and Car Audio 1 and Car Audio 2 are turned off.

[0088] It should be noted that when the number of users remains unchanged, only the change in seat angle and the change in CMS recognition determine the I value, i.e., I = (Δ 座椅角度 ) 主 +(Δ 座椅角度 ) 副 +(Δ 座椅角度 ) 后座 +Δ CMS ;

[0089] Among them, (Δ 座椅角度 ) 主 This represents the change in seat angle at the driver's position, (Δ) 座椅角度 ) 副 This represents the change in seat angle at the passenger side, (Δ) 座椅角度 ) 后座 This indicates the amount of change in the seat angle at the rear seat position.

[0090] In practice, the time interval between receiving audio playback input and outputting audio confirmation should be less than 1 second, and the automatic switching should be smooth.

[0091] In one embodiment, before controlling the vehicle audio system according to the control information of the vehicle audio system, the user's usage preference information can be confirmed according to the user login information, and then the vehicle audio system can be controlled according to the user's usage preference information.

[0092] Specifically, user preference information can be confirmed in the following two ways:

[0093] Method 1

[0094] When logging in, the sound effect preferences of the music playback app are synchronized. After the automatic adjustment function of the car audio is turned on, it is confirmed whether the current account's sound effect preferences have been successfully obtained. If not, the user needs to manually confirm the sound effects (first account login).

[0095] Method 2

[0096] When the automatic adjustment function is enabled, the user needs to select and confirm their sound effect preferences the first time the automatic adjustment function is enabled. The system will then bind and save these preferences in the background.

[0097] For ease of understanding, this application will be described in detail below with reference to specific embodiments.

[0098] The interior of the car is divided into three sections in advance: the driver's seat, the front passenger seat, and the rear seats.

[0099] User status confirmation: The number and location of people in the vehicle are confirmed through CMS cameras and seat sensors; the posture of people is confirmed through seat angle.

[0100] Target location confirmation and vehicle audio configuration classification: Based on the number of speakers and amplifier capabilities, the system is divided into two categories. When the vehicle audio system is the first configuration (high-end): There is one user position for each of the driver's seat, passenger seat, and rear seat, and each user position is considered as a target position, for a total of 3 target positions. When the vehicle audio system is the second configuration (low-end): There is only one target position. Based on the three user positions, there is one user position for each of the driver's seat, passenger seat, and rear seat, and one target position is determined.

[0101] Based on the same inventive concept, this application also provides an electronic device, the principle of which solves the problem is similar to that of any of the above-mentioned vehicle audio control methods, and the repetitions will not be repeated.

[0102] Figure 4 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention, such as...

[0103] The memory 41, as a computer-readable storage medium, can be used to store software programs, computer-executable programs, and modules, such as the program instructions / modules corresponding to the vehicle audio control method in this embodiment of the invention. The processor 40 executes various functional applications and data processing of the device by running the software programs, instructions, and modules stored in the memory 41, thereby realizing the aforementioned vehicle audio control method.

Examples of such networks include, but are not limited to, the Internet, intranets, local area networks, mobile communication networks, and combinations thereof.

[0105] Input device 42 can be used to receive input digital or character information, and to generate key signal inputs related to user settings and function control of the device. Output device 43 may include display devices such as a display screen.

[0106] Based on the same inventive concept, this application also provides a vehicle whose problem-solving principle is similar to that of any of the above-mentioned vehicle audio control methods, and the repetitions will not be repeated.

Then, based on the occupant information and the vehicle audio system configuration, the vehicle audio control information is determined. Finally, the vehicle audio system is controlled according to the control information. The occupant information includes the number of users, user positions, and user postures. Because the vehicle audio control information can be determined based on the occupant information and the vehicle audio system configuration, manual control is unnecessary, thus saving manual operation steps and improving the user experience.
