[0003] This application relates to the field of wireless communication technology, and in particular to an airflow regulation method, an airflow regulation device, and a vehicle. Background Technology

[0004] Currently, in-vehicle air conditioning controls automatically adjust the temperature and airflow to ensure comfortable breathing at the head level after the user sets the desired temperature. However, the air vents generate significant noise, which is particularly noticeable in the enclosed space of an electric vehicle, especially since there is no engine noise, thus impacting the driving and riding experience. User feedback indicates numerous complaints about the noise from the air conditioning vents, and users frequently manually adjust the airflow to lower it. Summary of the Invention

[0005] This application provides an airflow adjustment method, an airflow adjustment device, and a vehicle to determine a suitable airflow for the air conditioner.

[0006] In a first aspect, embodiments of this application provide an airflow adjustment method. This method can be applied to a device, such as a vehicle, a module within the vehicle (e.g., a circuit, chip, or chip system), or a logic node, logic module, or software capable of implementing all or part of the vehicle's functions. The method includes: determining a first noise value, which indicates the upper limit of the vehicle's interior noise; and determining a suggested range for the airflow based on the first noise value and a preset mapping relationship between the first noise value and a suggested range for the airflow from the air conditioner, wherein the suggested range for the airflow from the air conditioner includes one or more numerical values ​​indicating the magnitude of the airflow from the air conditioner.

[0007] Based on the above solution, the vehicle can determine the recommended range of airflow for the air conditioner according to the noise level, thereby realizing the determination of the appropriate airflow based on the noise level and improving the user experience.

[0008] In one possible implementation, determining the first noise value includes: determining the larger of the background noise value of the vehicle and the permissible in-vehicle noise value of the vehicle as the first noise value.

[0009] Based on the above scheme, the first noise value is accurately determined, which helps to accurately determine the recommended range of air conditioning air volume for the vehicle based on the first noise value, and thus determine the appropriate air conditioning air volume.

[0010] One possible implementation further includes: determining the background noise value of the vehicle based on the vehicle's external background noise value and the vehicle's interior cabin noise value; wherein the vehicle's external background noise value is determined based on at least one of the vehicle's speed, window opening / closing status, or road surface type surrounding the vehicle, and the vehicle's interior cabin noise value is determined based on at least one of the vehicle's audio system information, the vehicle's in-vehicle telephone information, or the acoustic characteristics of the vehicle's interior cabin.

[0011] Based on the above scheme, the background noise level of the vehicle can be accurately determined, which helps to accurately determine the recommended range of air conditioning airflow and thus determine the appropriate airflow.

[0012] One possible implementation method further includes: determining the permissible noise level inside the vehicle based on the vehicle's rest status information and / or the information from the in-vehicle telephone.

[0013] Based on the above scheme, the permissible noise level inside the vehicle can be accurately determined, which helps to accurately determine the recommended range of airflow for the vehicle's air conditioning system and thus determine the appropriate airflow for the air conditioning system.

[0014] One possible implementation method further includes: setting the adjustable range of the air conditioning airflow of the vehicle according to the recommended range of the air conditioning airflow of the vehicle.

[0015] Based on the above solution, limiting the adjustable range of the airflow of the air conditioner helps users select the appropriate airflow.

[0016] One possible implementation method further includes: receiving a first instruction, the first instruction instructing the air conditioning airflow of the vehicle to be adjusted to a first airflow; when the first airflow is included in the adjustable range of the air conditioning airflow, adjusting the air conditioning airflow of the vehicle to the first airflow.

[0017] Based on the above solution, limiting the adjustable range of the airflow of the air conditioner helps users select the appropriate airflow.

[0018] One possible implementation method further includes: displaying the noise level corresponding to the actual airflow rate selected by the user on the display screen using different colors, based on the recommended range of the airflow rate of the vehicle's air conditioning system.

[0019] Based on the above solution, the noise level corresponding to the airflow volume selected by the user is displayed using different colors, so that the user can accurately judge the noise generated by the selected airflow volume.

[0020] One possible implementation method further includes: sending a reminder message to the user when the second noise value generated by the airflow volume actually selected by the user exceeds the first noise value, or when the difference between the second noise value generated by the airflow volume actually selected by the user and the first noise value exceeds a noise threshold.

[0021] Based on the above solution, sending reminder messages to users helps them accurately determine the noise level generated by the selected airflow.

[0022] Secondly, this application provides an airflow regulating device that has the functions of the first aspect mentioned above. For example, the airflow regulating device includes modules, units or means corresponding to the operations involved in the first aspect mentioned above. The modules, units or means can be implemented by software, or by hardware, or by a combination of software and hardware.

[0023] Thirdly, this application provides an airflow regulating device, which includes an interface circuit and one or more processors. The one or more processors are coupled to a memory. The memory stores part or all of the necessary computer programs or instructions for implementing the functions described in the first aspect. The one or more processors can execute the computer programs or instructions, causing the airflow regulating device to implement the methods in any possible design or implementation of the first aspect. The interface circuit is used to implement communication functions within the airflow regulating device and / or communication functions between the airflow regulating device and other devices or components.

[0024] The aforementioned airflow regulating device may be a vehicle, a module in the vehicle (such as a circuit, chip, or chip system), or a logic node, logic module, or software that can realize all or part of the vehicle's functions.

[0029] Figure 3 is a possible exemplary block diagram of the air volume regulating device involved in the embodiments of this application. Detailed Implementation

[0030] Figure 1 is a schematic diagram of a possible application scenario provided by this application. In this application scenario, vehicle 101 and terminal 102 can communicate wirelessly. In Figure 1, terminal 102 is a mobile phone as an example.

[0031] Vehicle 101 includes any form of vehicle that supports wireless communication. Examples include intelligent vehicles, electric vehicles, digital cars, sedans, trucks, motorcycles, buses, lawnmowers, recreational vehicles, amusement park vehicles, construction equipment, trams, or golf carts, etc., which are not limited in this application. Exemplarily, vehicle 101 includes one or more components such as a gateway (GW), a vehicle computing platform (e.g., a mobile data center (MDC)), a human-machine interaction (HMI), a telematics control unit (TCU), a telematics box (Tbox), and an electronic control unit (ECU). The GW is a core component in the vehicle's electronic and electrical architecture, serving as the data interaction hub for the entire vehicle network, routing data from different networks such as the controller area network (CAN), local interconnect network (LIN), and media-oriented system transport (MOST) networks. MDC is the vehicle's intelligent in-vehicle computing platform, used to enable autonomous driving functions. HMI is the vehicle's infotainment system. TCU and Tbox are primarily used for communication with external devices (such as the cloud, fleet owners, terminals, etc.) and backend systems. ECU is a vehicle-specific microcomputer controller, including but not limited to the vehicle integrated / integration unit (VIU), cockpit domain controller (CDC), and vehicle domain controller (VDC). Furthermore, the vehicle may also include operating systems, navigation software, map software, and monitoring software.

[0032] As one implementation method, an in-vehicle intelligent system can be deployed within the HMI. This in-vehicle intelligent system supports voice interaction with users (such as the vehicle owner or other people) via TCU and / or Tbox, and also supports wireless communication with pre-bound terminals (such as the vehicle owner's mobile phone) via TCU and / or Tbox.

[0033] Terminal 102 can be used to manage vehicle 101, such as controlling vehicle 101 to start / stop, controlling vehicle 101's online upgrades; and can be used to receive information sent by vehicle 101, such as vehicle relocation requests; and can also establish a communication connection with vehicle 101's in-vehicle intelligent system, enabling the vehicle owner to make remote calls with people near the vehicle.

[0034] Terminal 102 can also be referred to as terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, etc. Terminals can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, etc. The embodiments of this application do not limit the device form of the terminal. Terminals typically contain communication modules, circuits, or chips that perform corresponding communication functions. The terminal can also be configured with program instructions for performing corresponding communication functions.

[0035] Vehicle 101 and terminal 102 can communicate via mobile communication networks (such as 5G or future communication networks) or wireless local area networks (WLANs), or via short-range communication technologies. In this embodiment, short-range communication technologies include, but are not limited to, Bluetooth, Wi-Fi, near field communication (NFC), Wi-Fi Aware, general short-range communication technologies, and short-range communication technologies specified by the Starlight Alliance.

[0036] It is understood that the form and quantity of vehicle 101 and terminal 102 shown in Figure 2 above are for illustrative purposes only and do not constitute a limitation of this application.

[0037] It should be noted that the application scenarios described above are for the purpose of more clearly illustrating the technical solution of this application and do not constitute a limitation on the technical solution provided in this application.

[0038] Currently, in-vehicle air conditioning controls automatically adjust the temperature and airflow to ensure comfortable breathing at the head level after the user sets the desired temperature. However, the air vents generate significant noise, which is particularly noticeable in the enclosed space of an electric vehicle, especially since there is no engine noise, thus impacting the driving and riding experience. User feedback indicates numerous complaints about the noise from the air conditioning vents, and users frequently manually adjust the airflow to lower it.

[0039] Determining the appropriate airflow volume for an air conditioner remains to be solved.

[0040] In view of the above problems, this application provides an air volume adjustment method, an air volume adjustment device, and a vehicle to achieve automatic adjustment of the air volume output of the vehicle air conditioner.

[0041] The airflow adjustment method, airflow adjustment device, and vehicle will be further described below with reference to the accompanying drawings. It is understood that the following method embodiments of this application can be executed by a vehicle, or by a module in the vehicle (e.g., a circuit, chip, or chip system, or one or more of the MDC, GW, ECU, HMI, TCU, Tbox, or ECU shown in Figure 1 above), or by a logic node, logic module, or software capable of implementing all or part of the vehicle's functions.

[0042] Figure 2 is a schematic flowchart of an airflow regulation method provided in an embodiment of this application. The method includes the following steps:

[0043] Step 201: The vehicle determines a first noise value, which is used to indicate the upper limit of the vehicle's interior noise.

[0044] Step 202: The vehicle determines the recommended range of air conditioning output based on the first noise value and the preset mapping relationship between the first noise value and the recommended range of air conditioning output.

[0045] The recommended airflow range for air conditioning includes one or more numerical values ​​indicating the airflow volume. For example, the recommended airflow range refers to the maximum recommended airflow volume set by the user, which can be represented as the recommended maximum air conditioning setting. Another example is a conservative (or optimal, most suitable) recommended airflow volume set by the user, which can be represented as the recommended optimal air conditioning setting. Users can choose an air conditioning setting near this optimal setting; for example, if the optimal setting is 5, users can prioritize setting 4, 5, or 6. Yet another example is multiple recommended airflow volume values, which can be represented as multiple recommended air conditioning settings, such as 6 and 7.

[0046] Based on the above solution, the vehicle can determine the recommended range of airflow for the air conditioner according to the noise level, thereby realizing the determination of the appropriate airflow based on the noise level and improving the user experience.

[0047] For example, the first noise value here can be the vehicle's background noise value, the vehicle's permissible interior noise value, or the larger of the vehicle's background noise value and the vehicle's permissible interior noise value. The vehicle's background noise value indicates the magnitude of background noise caused by the objective environment (e.g., noise from outside the windows and noise within the vehicle cabin). The permissible interior noise value indicates the upper limit of noise that the user can accept.

[0048] As one approach, a vehicle can determine its background noise level based on both the external background noise level and the internal cabin noise level. The internal cabin noise level is also referred to as the vehicle's internal background noise level.

[0049] For example, a vehicle can determine its external background noise level based on at least one of the following: vehicle speed, window opening / closing status, or road surface type (e.g., highway, city road). Vehicle speed can be obtained from the vehicle's speed sensor; generally, the faster the vehicle, the higher the external background noise level. Window opening / closing status can be obtained from window sensors; generally, the larger the window opening area, the higher the external background noise level. Road surface type can be obtained from sensors on the vehicle's navigation system and / or tires; generally, the more uneven or bumpy the road surface, the higher the external background noise level.

[0050] For example, a vehicle can determine its cabin noise level based on at least one of the following: information from the vehicle's audio system, information from the vehicle's hands-free phone, or information about the acoustic characteristics of the vehicle's interior cabin. Audio system information includes, for example, audio volume and power, and this information can be obtained through the vehicle's audio system. Generally, higher audio volume and / or power correlate with higher cabin noise levels. Hands-free phone information includes, for example, the phone's usage status (whether it's in use or not) and its volume. Generally, higher hands-free phone volume correlates with higher cabin noise levels. Information about the acoustic characteristics of the vehicle's interior cabin can be obtained through the vehicle's onboard controller.

[0051] For example, the background noise level of a vehicle can be calculated using the following formula:

[0052] Among them, L total The values ​​represent the vehicle's background noise level, with L1 representing the vehicle's exterior background noise level and L2 representing the vehicle's interior cabin noise level.

[0053] As one implementation method, the vehicle can determine the permissible noise level inside the vehicle based on the vehicle's rest status information and / or information from the in-vehicle phone. The vehicle's rest status information includes whether the seat sensors detect that the seat is in rest mode and / or other information about the vehicle cabin (e.g., whether the lights are off, whether the audio system is off). For example, the user is in a rest state if one or more of the following conditions are met: the seat is in rest mode, all lights are off, and all audio systems are off. Generally, when the user is in a rest state, the permissible noise level inside the vehicle is lower. The in-vehicle phone information includes, for example, the phone's usage status (i.e., used or not used) and the phone's volume. Generally, the lower the in-vehicle phone volume, the lower the permissible noise level inside the vehicle, allowing the user to make phone calls normally.

[0054] As one implementation method, the vehicle can pre-store a mapping relationship between multiple noise values ​​and multiple recommended airflow ranges for the air conditioning system. Then, based on this mapping relationship and the actually determined first noise value, the recommended airflow range for the air conditioning system is determined. Generally, the smaller the first noise value, the smaller the recommended airflow range for the air conditioning system. This is because: the smaller the first noise value, the smaller the airflow should be, so that the noise from the air conditioning system is masked by the noise corresponding to the first noise value, thus preventing the noise from the air conditioning system from increasing the overall noise level.

[0055] For example, Table 1 below provides an example of this mapping relationship. It is assumed that there are 9 air conditioning speed settings, and the higher the speed number, the greater the air volume.

[0056] Table 1

[0057] For example, if the first noise value is greater than or equal to noise value #5 and less than noise value #6, then the recommended range for the air conditioning output air volume is 6 to 8.

[0058] For example, Table 2 below provides another example of this mapping relationship. It is assumed that there are 9 air conditioning speed settings, and the higher the speed number, the greater the air volume.

[0059] Table 2

[0060] For example, if the first noise value is greater than or equal to noise value #5 and less than noise value #6, then the recommended range for the air conditioning output air volume is 1 to 8.

[0061] Tables 1 and 2 above are just examples. In actual applications, the mapping relationship between noise values ​​and the recommended range of air conditioning output air volume can be set as needed.

[0062] As one implementation method, after step 202 above, the vehicle can further set the adjustable range of its air conditioning vents based on the recommended range. That is, the vehicle sets the adjustable range of its air conditioning vents to the recommended range, so that when adjusting the air conditioning vents, the user can only select from within this recommended range. For example, if the air conditioning vent range is 6 to 8, then the vehicle sets the adjustable range to 6 to 8, allowing the user to choose only one vent level from 6 to 8. Based on this method, users can select a suitable air conditioning vent, reducing noise interference from the airflow. Optionally, when the vehicle receives a first instruction, the first instruction instructs the air conditioning airflow to be adjusted to a first airflow. If the first airflow is within the adjustable range of the air conditioning airflow, the air conditioning airflow is adjusted to the first airflow. If the first airflow is not within the adjustable range of the air conditioning airflow, the first instruction is rejected, for example, by reminding the user through a display screen or voice that it cannot be adjusted to the first airflow.

[0063] As one implementation method, after step 202 above, the vehicle can also display the noise level corresponding to the user's actual selected air conditioning airflow level on the display screen using different colors, based on the vehicle's recommended airflow range. For example, assuming the vehicle's recommended airflow range is 2 to 4, if the user actually selects any of the levels 1 to 4, the selected airflow will be displayed in green, indicating a low noise level. If the user selects any of the levels 5 to 6, the selected airflow will be displayed in yellow, indicating a medium noise level. If the user selects any of the levels 7 to 9, the selected airflow will be displayed in red, indicating a high noise level.

[0064] As one implementation method, when the second noise value generated by the airflow actually selected by the user exceeds the first noise value, or when the difference between the second noise value and the first noise value exceeds a noise threshold, a reminder message is sent to the user. This reminder can be sent via voice or text on the vehicle's screen. The noise threshold can be a preset value or a user-defined value; this application does not limit this. The reminder message may include one or more of the following: airflow is too high, airflow is too loud, or the airflow needs to be increased further.

[0065] It should be noted that all noise values ​​in this application refer to the magnitude or volume of noise. Therefore, the noise values ​​in this application can be replaced with the magnitude or volume of noise.

[0066] Figure 3 shows a possible exemplary block diagram of the airflow regulating device involved in the embodiments of this application. As shown in Figure 3, the airflow regulating device 300 may include modules or units for implementing the methods described above. In one possible design, the airflow regulating device 300 includes a noise value determination unit 301 and an airflow determination unit 302. Optionally, the airflow regulating device 300 may also include one or more of the following units: an airflow setting unit 303, an airflow regulating unit 304, an instruction receiving unit 305, a display unit 306, or an alert unit 307.

[0067] The airflow regulating device 300 can be the vehicle in the above embodiments, a module in the vehicle (e.g., a circuit, chip, or chip system), or a logic node, logic module, or software that can realize all or part of the vehicle's functions. For example, the functions of each unit in FIG3 can be implemented by one or more of the MDC, ECU, HMI, TCU, Tbox, GW, or ECU shown in FIG1. ​​This application does not limit the relationship between these units and the various parts in FIG1.

[0068] For example, in one embodiment, the noise value determination unit 301 is used to determine a first noise value, which is used to indicate the upper limit of the vehicle's interior noise; the air volume determination unit 302 is used to determine the recommended range of the vehicle's air conditioning air volume based on the first noise value and a preset mapping relationship between the first noise value and the recommended range of the air conditioning air volume, wherein the recommended range of the air conditioning air volume includes one or more values ​​indicating the size of the air conditioning air volume.

[0069] In one possible implementation, the noise value determination unit 301 is used to determine a first noise value, including: determining the larger of the background noise value of the vehicle and the permissible noise value inside the vehicle as the first noise value.

[0070] In one possible implementation, the noise value determination unit 301 is further configured to determine the background noise value of the vehicle based on the vehicle's external background noise value and the vehicle's interior cabin noise value; wherein the vehicle's external background noise value is determined based on at least one of the vehicle's speed, window opening / closing status, or road surface type surrounding the vehicle, and the vehicle's interior cabin noise value is determined based on at least one of the vehicle's audio system information, the vehicle's in-vehicle telephone information, or the acoustic characteristics of the vehicle's interior cabin.

[0071] For example, the vehicle's external background noise value is obtained through a first sensor installed on the vehicle body.

[0072] For example, the cabin noise level of the vehicle is obtained by a second sensor installed inside the vehicle.

[0073] In one possible implementation, the noise value determination unit 301 is further configured to determine the permissible noise value inside the vehicle based on the vehicle's rest status information and / or the information of the in-vehicle telephone inside the vehicle.

[0074] In one possible implementation, the air volume setting unit 303 is used to set the adjustable range of the air volume of the vehicle's air conditioning system according to the recommended range of the air volume of the vehicle's air conditioning system.

[0075] In one possible implementation, the instruction receiving unit 305 is used to receive a first instruction, which instructs the air conditioning airflow of the vehicle to be adjusted to a first airflow; the airflow adjustment unit 304 is used to adjust the air conditioning airflow of the vehicle to the first airflow when the first airflow is included in the adjustable range of the air conditioning airflow.

[0076] For example, the instruction receiving unit 305 may be a voice input unit or a physical button touch unit.

[0077] In one possible implementation, the display unit 306 is used to display the noise level corresponding to the air conditioning airflow rate actually selected by the user on the display screen using different colors, based on the recommended range of the air conditioning airflow rate of the vehicle.

[0078] In one possible implementation, the reminder unit 307 is used to send a reminder message to the user when the second noise value generated by the airflow volume actually selected by the user exceeds the first noise value, or when the difference between the second noise value generated by the airflow volume actually selected by the user and the first noise value exceeds a noise threshold.

[0079] For example, the reminder unit 307 may be a voice output unit or a display.

[0080] It is understood that the division of units in the above-described device is merely a logical functional division.
