[0052] It should be understood that the specific embodiments described herein are merely used to explain the technical solutions of the present application and are not intended to limit the present application.

[0053] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0054] The main solution of the embodiment of the present application is: in response to occupant request instructions for different temperature zones, determine the target exhaust volume gear and target temperature of each temperature zone according to the occupant request instructions for the different temperature zones, wherein the temperature zones include at least the first to fourth temperature zones; perform damper control according to the target exhaust volume gear and the target temperature of each temperature zone to obtain the actual exhaust volume gear and actual temperature of each temperature zone; when the actual exhaust volume gear of each temperature zone is consistent with the target exhaust volume gear of the corresponding temperature zone and the actual temperature reaches the target temperature, determine the damper motor motion strategy of the corresponding temperature zone according to the target exhaust volume gear of each temperature zone; adjust the damper motor speed of the corresponding temperature zone according to the damper motor motion strategy to achieve vehicle air conditioning noise control.

[0055] Due to the rapid development of today's high-end new energy vehicle industry, vehicle air conditioning systems are all designed to be automatic, leading to the emergence of four-zone air conditioning. Four-zone air conditioning means that each of the four passenger positions in the vehicle has a separate control panel with a temperature field, allowing each position to have its own unique air conditioning temperature field. When adjusting the temperature, air volume, mode, and other settings on the air conditioning interface, different mechanical structures begin to operate, generating a certain amount of noise. Different air volume distributions create different sound fields, resulting in different air conditioning noise levels in different temperature zones, affecting the user experience. Therefore, how to effectively control the air conditioning noise in different temperature zones and improve the sound quality of the air conditioning is a pressing issue.

[0056] The present application determines the target exhaust volume level and target temperature of each temperature zone according to the occupant request instructions in different temperature zones and performs damper control. When the air volume level and temperature are adjusted to meet the requirements, the damper motor movement strategy is determined according to the exhaust volume level of each temperature zone, and then the damper motor speed of the corresponding temperature zone is adjusted to make the motor noise of each temperature zone adapt to the wind noise, overcoming the technical defects of different mechanical structures starting to operate, which will generate certain noise, different air volume distribution will create different sound fields, resulting in different temperature zones having their own air-conditioning noise, and affecting the user experience. The application can effectively control the air-conditioning noise in different temperature zones and improve the air-conditioning sound quality.

[0057] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a tablet computer, personal computer, mobile phone, etc., or an electronic device capable of implementing the above functions, such as an in-vehicle air conditioning noise control device. The following uses the in-vehicle air conditioning noise control device as an example to illustrate this embodiment and the following embodiments.

[0058] Based on this, the embodiment of the present application provides a method for controlling noise of a vehicle air conditioner, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle air-conditioning noise control method of the present application.

[0059] In this embodiment, the vehicle air conditioner noise control method includes steps S10 to S40:

[0060] Step S10 , in response to occupant request instructions for different temperature zones, determining target exhaust air volume levels and target temperatures for respective temperature zones according to the occupant request instructions for the different temperature zones, wherein the temperature zones include at least first to fourth temperature zones.

[0061] It should be noted that the passenger request command can be input through the vehicle air conditioning control panel, or through voice recognition, a touch screen, or other user interface. The request command may include parameters such as temperature setting, exhaust volume setting, and wind direction setting, which are not specifically limited in this embodiment.

[0062] Understandably, in this example, the vehicle's air conditioning system is divided into four temperature zones, namely zones 1 through 4. The control panel for each temperature zone can be independently adjusted to meet the needs of different passengers. However, this zoning control may result in inconsistent air conditioning system noise during operation, affecting the overall passenger experience. Therefore, it is necessary to control the air conditioning noise in each temperature zone to ensure that the operation of the air conditioning in each temperature zone does not negatively impact other areas.

[0063] It's worth noting that the first and second temperature zones are for the driver and front passenger areas, respectively, and the third and fourth zones correspond to the left and right rear passenger areas. Each temperature zone's control panel features temperature adjustment buttons, air volume adjustment knobs, and air direction selector switches, allowing passengers to customize settings based on their preferences and needs.

[0064] In practice, passenger requests can be used to determine the airflow and temperature settings for different temperature zones, enabling precise control of the air conditioning system. For example, if the driver desires a temperature of 24°C and airflow level 2, while the passenger desires a temperature of 22°C and airflow level 5, the system will adjust the air conditioning parameters for the corresponding temperature zones based on these requests.

[0065] Step S20 , performing damper control according to the target exhaust volume level and the target temperature of each temperature zone to obtain the actual exhaust volume level and actual temperature of each temperature zone.

[0066] It should be noted that a damper is a device that controls the direction and amount of air flow. In this embodiment, damper control is achieved by adjusting the damper opening in each temperature zone. The system automatically adjusts the damper opening based on the target exhaust volume level and target temperature to ensure that each temperature zone receives the required air volume and temperature.

[0067] In a feasible embodiment, step S20 may include: adjusting the opening of the air volume control damper and the air volume distribution damper according to the target exhaust volume level of each temperature zone to obtain the actual exhaust volume level of each temperature zone; adjusting the opening of the temperature mixing damper according to the target temperature of each temperature zone to obtain the actual temperature of each temperature zone.

[0068] It should be noted that the exhaust volume gear and exhaust volume gear are controlled by different dampers, among which the exhaust volume gear is determined by the air volume control damper and the air volume distribution damper, while the temperature is determined by the temperature mixing damper, thereby ensuring that the air flow and temperature in each temperature zone reach the target value set by the occupants.

[0069] It's understood that the air volume control damper regulates the total air volume passing through the air conditioning system, while the air volume distribution damper distributes air to each temperature zone. By precisely controlling the opening of these two dampers, the system ensures that each temperature zone receives the appropriate amount of air, thereby meeting the occupants' desired air volume levels for different temperature zones. The temperature mixing damper adjusts the mixture of cold and hot air to achieve the target temperature set by the occupants. For example, if a temperature zone requires cooler air, the system increases the proportion of cool air; conversely, if warmer air is required, the proportion of hot air is increased. In this way, the system provides personalized temperature control for each temperature zone.

[0070] It is worth noting that after completing the damper control, the actual exhaust volume level and actual temperature of each temperature zone are monitored to determine whether the exhaust volume level and temperature required by the occupants are met.

[0071] In a feasible embodiment, the openings of the air volume control damper and the air volume distribution damper are adjusted according to the target exhaust volume gear of each temperature zone to obtain the actual exhaust volume gear of each temperature zone, including: adjusting the openings of the first air volume control damper and the first air volume distribution damper according to the first target exhaust volume gear of the first temperature zone and the second target exhaust volume gear of the second temperature zone to obtain the first actual exhaust volume gear of the first temperature zone and the second actual exhaust volume gear of the second temperature zone; adjusting the openings of the second air volume control damper and the second air volume distribution damper according to the third target exhaust volume gear of the third temperature zone and the fourth target exhaust volume gear of the fourth temperature zone to obtain the third actual exhaust volume gear of the third temperature zone and the fourth actual exhaust volume gear of the fourth temperature zone.

[0072] It should be noted that the first air volume control damper is the air volume control damper for the front row of the vehicle, used to adjust the air volume required by the left and right temperature zones of the front row. The first air volume distribution damper is the left and right air volume distribution damper for the front row of the vehicle, used to distribute air to the left and right temperature zones of the front row. By precisely controlling the opening of these two dampers, the system can ensure that the front passengers receive the appropriate amount of air, thereby meeting their exhaust volume requirements.

[0073] It can be understood that the second air volume control damper is the air volume control damper for the rear row of the vehicle, which is used to adjust the total air volume on both sides of the rear row of the vehicle, and the second air volume distribution damper is the left and right air volume distribution damper for the rear row of the vehicle, which is used to distribute air to the temperature zones on the left and right sides of the rear row. By precisely controlling the opening of these two dampers, the system can ensure that the rear passengers obtain the appropriate amount of air, thereby meeting their needs for exhaust volume gear.

[0074] In a specific implementation, the openings of the vehicle's front-row air volume control dampers and the vehicle's front-row left and right air volume distribution dampers are controlled based on the exhaust volume level requirements of the left and right front-row temperature zones. The actual exhaust volume levels of the left and right front-row temperature zones after the dampers are adjusted, namely the first target exhaust volume level and the second target exhaust volume level, are collected to ensure that the adjustment results meet the target values ​​set by the occupants. Similarly, the openings of the vehicle's rear-seat air volume control dampers and the vehicle's rear-seat left and right air volume distribution dampers are controlled based on the exhaust volume level requirements of the left and right rear-seat temperature zones. The actual exhaust volume levels of the left and right rear-seat temperature zones after the dampers are adjusted, namely the third actual exhaust volume level and the fourth actual exhaust volume level, are collected to ensure the comfort of the rear-seat passengers.

[0075] In a feasible embodiment, the adjusting the opening of the temperature mixing damper according to the target temperature of each temperature zone to obtain the actual temperature of each temperature zone includes: adjusting the opening of the first temperature mixing damper according to the first target temperature of the first temperature zone and the second target temperature of the second temperature zone to obtain the first actual temperature of the first temperature zone and the second actual temperature of the second temperature zone; adjusting the opening of the second temperature mixing damper according to the third target temperature of the third temperature zone and the fourth target temperature of the fourth temperature zone to obtain the third actual temperature of the third temperature zone and the fourth actual temperature of the fourth temperature zone.

[0076] It should be noted that the first temperature mixing damper refers to the vehicle's front row mixing damper, which is used to adjust the hot and cold air mixing ratio in the front left and right temperature zones to achieve the target temperature set by the occupants. The second temperature mixing damper refers to the vehicle's rear row mixing damper, which is used to adjust the hot and cold air mixing ratio in the rear left and right temperature zones.

[0077] In a specific implementation, the vehicle's front air blend door opening is adjusted based on the desired temperature of the left and right front temperature zones, and the actual temperatures of the adjusted left and right front temperature zones, namely the first and second actual temperatures, are collected to ensure that the adjustment results meet the target values ​​set by the occupants. Similarly, the vehicle's rear air blend door opening is adjusted based on the desired target temperature of the left and right rear temperature zones, and the actual temperatures of the adjusted left and right rear temperature zones, namely the third and fourth actual temperatures, are collected to ensure the comfort of the rear passengers.

[0078] like Figure 2 As shown, Figure 2 This is the schematic diagram of the four-zone front and rear hot and cold air distribution system. Air is drawn in through the internal and external circulation air inlets and transferred to the blower, which then drives the air into the vehicle's air conditioning system. In the air conditioning system, the air first passes through a filter to remove dust and impurities, ensuring the cleanliness of the air entering the vehicle. The air is then divided into four paths: one enters the front mixing door, and one enters the rear mixing door, generating front and rear cold air, respectively. The other two paths enter the heater core, generating front and rear warm air, respectively. In the heater core, the coolant exchanges heat with the air through the radiator, heating the air.

[0079] like Figure 3 As shown, Figure 3 This is the schematic diagram of the four-zone air conditioning system's hot and cold air mixing and air direction distribution. The front row cold and hot air are each passed through two front row temperature mixing dampers, where they are mixed according to the passenger's target temperature. The mixed air passes through the front row air volume control dampers for volume control, and then through the front row left and right air volume distribution dampers to distribute the air to the left and right front row air outlets. The rear row cold and hot air enter the rear row temperature mixing dampers, where they are mixed according to the rear row passenger's target temperature. The mixed air passes through the rear row air volume control dampers for volume control, and then through the rear row left and right air volume distribution dampers to distribute the air to the left and right rear row air outlets.

[0080] Step S30 , when the actual exhaust volume level of each temperature zone is consistent with the target exhaust volume level of the corresponding temperature zone and the actual temperature reaches the target temperature, determining the damper motor movement strategy of the corresponding temperature zone according to the target exhaust volume level of each temperature zone.

[0081] It should be noted that when the actual exhaust volume level of each temperature zone is consistent with the target exhaust volume level of the corresponding temperature zone and the actual temperature reaches the target temperature, it indicates that the air volume and temperature requirements at each position have been achieved.

[0082] It can be understood that the damper motor movement strategy refers to formulating a corresponding damper motor movement plan based on the target exhaust volume level of each temperature zone, adjusting the engine speed at an appropriate speed, and thus controlling the noise of the air conditioner.

[0083] It is worth mentioning that the front and rear exhaust air volume gears can be adjusted at will, and the size of the air volume at different gears is achieved through the front and rear air volume control dampers. When the front and rear exhaust air volumes are adjusted manually or automatically, the noise environment will appear in different scenarios. When the air volume control damper moves, the operating noise of the damper motor and the noise caused by the change of the gas flow field will appear. The sound quality of these two noises is completely different. The motor noise is mainly electromagnetic noise, which appears as a "whistling sound", while the flow field change noise is the change of fluid wind sound caused by the decrease and increase of air flow, and there is a big difference in sound quality. When the air volume gear is low, the air volume is small, the wind noise is small, and the damper movement is mainly manifested as motor noise; when the air volume gear is high, the air volume is large, and the wind noise is large, which can cover up the motor noise of the damper movement. Therefore, during the damper adjustment process, it is necessary to distinguish between high and low air volume gears. In low gear, the wind noise is small, and the motor needs to move quickly to the designed position. In high gear, the motor needs to move slowly to allow the larger wind noise to change slowly. In this way, the wind noise change is not abrupt and can cover up the noise of the slow movement of the motor, thereby achieving noise control.

[0084] In a feasible implementation, the "determining the damper motor movement strategy for the corresponding temperature zone according to the target exhaust volume gear of each temperature zone" in step S30 may include: when the target exhaust volume gear of each temperature zone reaches a first preset gear, determining the damper motor movement strategy for the corresponding temperature zone to be a first movement strategy; when the target exhaust volume gear of each temperature zone reaches a second preset gear, determining the damper motor movement strategy for the corresponding temperature zone to be a second movement strategy.

[0085] It should be noted that the first preset gear can be gear 3, and the second preset gear can be gear 5. This embodiment does not impose any specific restrictions on this. This embodiment uses gear 3 and gear 5 as examples for explanation. At gears 3 and below, the wind noise background of the entire air-conditioning system is relatively small, and the movement of the damper motor can be easily perceived by the passengers. Therefore, the movement of the damper motor needs to quickly execute the designed target speed, that is, the first movement strategy is a fast movement strategy. At gears 5 and above, the wind noise background of the entire air-conditioning system is very large, and the movement of the damper motor is not easily perceived by the passengers. However, the rapid operation of the damper will cause the flow field to change rapidly, resulting in a sharp and abrupt change in wind noise. Therefore, the movement of the damper motor needs to be controlled to execute the movement quietly to the designed target speed, that is, the second movement strategy is a slow movement strategy. Through this strategy, it can be ensured that at different air volume gears, the movement of the damper motor and the change in wind noise are coordinated with each other, thereby achieving noise control.

[0086] Step S40 , adjusting the speed of the damper motor in the corresponding temperature zone according to the damper motor movement strategy to achieve vehicle air conditioning noise control.

[0087] It should be noted that the damper motor motion strategy includes fast and slow motion strategies. Depending on the corresponding motion strategy, the damper motor speed can be controlled to switch quickly or slowly at different temperatures. Under the fast motion strategy, the damper motor speed will quickly increase to the target speed to meet the requirements of low air volume settings, ensuring that the damper quickly reaches the designed position and reducing the passenger's perception of motor noise. Under the slow motion strategy, the damper motor speed will gradually increase to avoid sudden changes in wind noise, so that the damper motor movement and wind noise changes are coordinated, thereby achieving noise control.

[0088] The present embodiment provides a method for controlling vehicle air-conditioning noise. The present embodiment first responds to occupant request instructions for different temperature zones, and determines a target exhaust volume gear and a target temperature for each temperature zone according to the occupant request instructions for the different temperature zones, wherein the temperature zones include at least first to fourth temperature zones; damper control is performed according to the target exhaust volume gear and the target temperature for each temperature zone to obtain an actual exhaust volume gear and an actual temperature for each temperature zone; when the actual exhaust volume gear of each temperature zone is consistent with the target exhaust volume gear of the corresponding temperature zone and the actual temperature reaches the target temperature, a damper motor motion strategy for the corresponding temperature zone is determined according to the target exhaust volume gear of each temperature zone; the damper motor speed for the corresponding temperature zone is adjusted according to the damper motor motion strategy to achieve vehicle air-conditioning noise control, which can effectively control the air-conditioning noise in different temperature zones and improve the air-conditioning sound quality.

[0089] In summary, this embodiment determines the target exhaust volume level and target temperature of each temperature zone according to the occupant request instructions for different temperature zones and performs damper control. When the air volume level and temperature are adjusted to meet the requirements, the damper motor movement strategy is determined according to the exhaust volume level of each temperature zone, and then the damper motor speed of the corresponding temperature zone is adjusted to make the motor noise of each temperature zone adapt to the wind noise, overcoming the technical defects of different mechanical structures starting to operate, which will generate certain noise, different air volume distribution will create different sound fields, resulting in different temperature zones having their own air-conditioning noise, and affecting the user experience. The embodiment can effectively control the air-conditioning noise in different temperature zones and improve the air-conditioning sound quality.

[0090] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above embodiment 1 can be referred to the above introduction and will not be described in detail later. Figure 4 , the step S40 further includes steps S401-S403:

[0091] Step S401 : determining a target speed of the damper motor for each temperature zone according to the target exhaust volume level of each temperature zone and a correlation between the exhaust volume level and the speed of the damper motor.

[0092] It should be noted that the correlation between the exhaust volume gear and the damper motor speed is obtained through experiments or calculations, which can ensure that at different exhaust volume gears, the damper motor speed and the exhaust volume are optimally matched, thereby achieving a balance between noise control and air volume distribution.

[0093] In a feasible implementation, before step S401, the method may further include: collecting motor noise at different damper motor speeds and wind noise at different exhaust volume gears; determining a correlation between wind noise parameters and motor noise parameters based on the motor noise at different damper motor speeds and the wind noise at different exhaust volume gears; and determining a correlation between exhaust volume gear and damper motor speed based on the correlation between wind noise parameters and motor noise parameters.

[0094] It should be noted that the motor noise at various operating speeds of the motor and the wind noise at different exhaust volume gears are tested, and the various sound quality parameters of the motor noise and wind noise (i.e., wind noise parameters and motor noise parameters) are compared to obtain a wind noise table at different exhaust volume gears and a motor noise table at various operating speeds of the motor.

[0095] As shown in Table 1, Table 1 is a table of wind noise under different gears, which includes the exhaust volume gear and the sound quality parameters of wind noise. The exhaust volume gear includes gear 1, gear 2, gear 3, etc. The sound quality parameters of wind noise include sound pressure level, sharpness and loudness.

[0096] As shown in Table 2, Table 2 is a table of motor noise at various operating speeds of the motor. The table includes the sound quality parameters of the motor speed and motor noise. The motor speed includes V1, V2, V3, etc. The sound quality parameters of the motor noise include sound pressure level, sharpness and loudness.

[0101] It's worth noting that at low gear, wind noise is low, requiring the motor to quickly move to the designed position. At high gear, the motor needs to move slowly, allowing the louder wind noise to change gradually. This way, the wind noise changes less abruptly and masks the noise of the motor's slow movement. The correlation between the various wind noise parameters and the motor noise parameters is: wind noise - motor noise > -1 at a certain gear. Based on the correlation between the various wind noise parameters and motor noise parameters, the correlation between specific gears and motor speeds can be determined. Because the noise characteristics of each blower vary greatly, the operating speed of the damper motor at different gears also varies significantly.

[0102] like Figure 5 As shown, Figure 5 This is a relationship diagram between the air conditioning gear and the air volume damper movement speed. It can be seen from the figure that after the air conditioning gear exceeds 2 gears, that is, between 2 gears and 5 gears, the higher the air conditioning gear is, the slower the air volume damper movement speed is. When the gear is above 5 gears, the air volume damper movement speed remains basically unchanged.

[0103] like Figure 6 As shown, Figure 6 This is a relationship diagram between the air conditioning gear and the mixing damper movement speed. It can be seen from the figure that after the air conditioning gear exceeds 2 gears, that is, between 2 gears and 5 gears, the higher the air conditioning gear is, the slower the mixing damper movement speed is. When the gear is above 5 gears, the mixing damper movement speed remains basically unchanged.

[0104] Step S402 : When the damper motor motion strategy is the first motion strategy, the damper motor speed in the corresponding temperature zone is adjusted to the damper motor target speed according to the first motion strategy.

[0105] It should be noted that the first motion strategy is a fast motion strategy. Under the fast motion strategy, it is necessary to quickly respond and adjust the speed of the damper motor so that the speed of the damper motor quickly moves to the target value.

[0106] In the specific implementation, if the four passenger positions request the 3rd wind speed of 23℃ for the left side of the front row, the 1st wind speed of 25℃ for the right side of the front row, the 3rd wind speed of 18℃ for the left side of the rear row, and the 2nd wind speed of 20℃ for the right side of the rear row, then the entire air mixing system and air volume distribution system need to mix and distribute the air according to the changes in the temperature sensor to achieve reasonable distribution and realize the air volume and temperature requirements of each position. At this time, for the air volume of 3rd wind speed and below, the wind noise background noise of the entire air-conditioning system is relatively small, and the movement of the damper motor can be easily noticed by the passengers. Therefore, the movement of the damper motor needs to be controlled to quickly execute to the target speed.

[0107] Step S403 : When the damper motor motion strategy is the second motion strategy, the damper motor speed in the corresponding temperature zone is adjusted to the damper motor target speed according to the second motion strategy.

[0108] It's important to note that the second strategy, Slow, requires smooth and gradual adjustments to the damper motor speed to avoid abrupt changes in wind noise and the presence of motor movement noise. Especially in high gears, where wind noise increases, Slow can leverage the natural masking effect of wind noise, making the motor movement sound less noticeable and improving interior comfort.

[0109] In the specific implementation, if the four passenger positions request 8-speed wind 18℃ for the left side of the front row, 7-speed wind 20℃ for the right side of the front row, 8-speed wind 17℃ for the left side of the rear row, and 6-speed wind 20℃ for the right side of the rear row, the entire air mixing system and air volume distribution system need to perform air mixing and distribution according to the changes in the temperature sensor to achieve reasonable distribution and realize the air volume and temperature requirements of each position. For 5-speed and above air volumes, the wind noise background noise of the entire air-conditioning system is very large, and the movement of the damper motor is not easily noticed by the passengers, but the rapid operation of the damper will cause the flow field to change rapidly, resulting in a sharp and abrupt change in wind noise. Therefore, the movement of the damper motor needs to be manually controlled to silently execute the movement to the target speed.

[0110] In this embodiment, by controlling the damper generator to move quickly or slowly to the target speed according to the movement strategy of different temperature zones, the changes in the damper motor noise and the wind noise are coordinated with each other, thereby achieving noise control.

[0111] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the vehicle air-conditioning noise control method of the present application. More simple transformations based on this technical concept are all within the scope of protection of the present application.
