[0052] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used 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 the 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 movement 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 movement strategy to achieve vehicle air conditioning noise control.

[0055] Due to the rapid development of today's high-end new energy vehicle industry, the air conditioning systems of vehicles are all designed as automatic air conditioning, and four-zone air conditioning has come into being. Four-zone air conditioning means that the four passenger positions of the vehicle are designed with a control panel with a separate controller temperature field, which can realize the scenario where each position has its own request for the air conditioning temperature field. When adjusting the temperature, air volume, mode and other requests on the air conditioning operation interface, different mechanical structures start to operate, which will produce certain noise. Different air volume distribution will create different sound fields, resulting in different air conditioning noises in different temperature zones, affecting user experience. Therefore, how to effectively control the air conditioning noise in different temperature zones and improve the sound quality of air conditioning is a problem that needs to be solved urgently.

[0056] The present application 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 problem that different mechanical structures will generate certain noise when they start to operate, and different air volume distribution will create different sound fields, resulting in different temperature zones having their own air-conditioning noise, which affects the technical defect of user experience. The air-conditioning noise in different temperature zones can be effectively controlled and the air-conditioning sound quality can be improved.

[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 running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a vehicle air conditioning noise control device, etc. The following takes the 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 vehicle air conditioning noise control method, 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 conditioning noise control method includes steps S10 to S40:

[0060] Step S10 , in response to occupant request commands of different temperature zones, determining a target exhaust air volume level and a target temperature of each temperature zone according to the occupant request commands of 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 instruction may be input through the vehicle air conditioning control panel, or may be input through voice recognition, a touch screen or other user interfaces. The request instruction may include parameters such as temperature setting, exhaust volume gear setting, wind direction setting, etc., which are not specifically limited in this embodiment.

[0062] It is understandable that in this example, the vehicle air conditioner is divided into four temperature zones, namely the first to fourth temperature zones, and the control panel of each temperature zone can be adjusted independently to meet the needs of different passengers. However, this zoning control may cause the air conditioning system to produce uncoordinated noise during operation, affecting the overall riding experience. Therefore, it is necessary to control the air conditioning noise of each temperature zone to ensure that the operation of the air conditioning in each temperature zone will not have a negative impact on other areas.

[0063] It is worth mentioning that the first and second temperature zones are the driver area and the front passenger area, that is, the left and right areas of the front row, while the third and fourth temperature zones correspond to the left and right passenger areas of the rear row. The control panel of each temperature zone is equipped with a temperature adjustment button, air volume adjustment knob and air direction selection switch, so that passengers can make personalized settings according to their personal preferences and needs.

[0064] In the specific implementation, the passenger's exhaust volume gear and temperature requirements for different temperature zones can be determined according to the passenger's request instructions, thereby achieving precise control of the air conditioning system. For example, if the driver wants the temperature to be set to 24°C and the exhaust volume gear to be set to gear 2, while the co-pilot wants the temperature to be set to 22°C and the exhaust volume gear to be set to gear 5, the system will adjust the air conditioning parameters of the corresponding temperature zones according to these instructions.

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

[0066] It should be noted that the damper refers to a device that controls the direction and amount of air flow. In this embodiment, the damper control is achieved by adjusting the damper opening of each temperature zone. The system will automatically adjust the damper opening according to the target exhaust air volume gear and target temperature to ensure that each temperature zone can obtain the required air volume and temperature.

[0067] In a feasible implementation, 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, and the temperature is determined by the temperature mixing damper, so as to ensure that the air flow and temperature in each temperature zone reach the target value set by the occupants.

[0069] It is understandable that the air volume control damper is a device used to adjust the total amount of air passing through the air conditioning system, while the air volume distribution damper is responsible for distributing the air to each temperature zone. By accurately controlling the opening of these two dampers, the system can ensure that each temperature zone obtains the appropriate amount of air, thereby meeting the passengers' requirements for the exhaust volume level of different temperature zones. The temperature mixing damper is used to adjust the mixing ratio of cold and hot air to achieve the target temperature set by the passengers. For example, if a certain temperature zone requires colder air, the system will increase the proportion of cold air; conversely, if warmer air is required, the proportion of hot air will be increased. In this way, the system can provide personalized temperature control for each temperature zone.

[0070] It is worth mentioning 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 implementation manner, 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, which is used to adjust the air volume required for the temperature zones on the left and right sides 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, which is used to distribute air to the temperature zones on the left and right sides of the front row. By accurately controlling the opening of these two dampers, the system can ensure that the front row passengers get the appropriate amount of air, thereby meeting their needs for the exhaust volume gear.

[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 get the appropriate amount of air, thereby meeting their needs for exhaust volume gears.

[0074] In a specific implementation, the openings of the air volume control damper and the air volume distribution damper in the front row of the vehicle are controlled by the exhaust volume gear requirements of the temperature zones on the left and right sides of the front row, and the actual exhaust volume gears of the temperature zones on the left and right sides of the front row after the damper adjustment, i.e., the first target exhaust volume gear and the second target exhaust volume gear, are collected to ensure that the adjustment result meets the target value set by the occupants. Similarly, the openings of the air volume control damper and the air volume distribution damper in the rear row of the vehicle are controlled by the exhaust volume gear requirements of the temperature zones on the left and right sides of the rear row, and the actual exhaust volume gears of the temperature zones on the left and right sides of the rear row after the damper adjustment, i.e., the third actual exhaust volume gear and the fourth actual exhaust volume gear, are collected to ensure the comfort of the rear passengers.

[0075] In a feasible implementation manner, the opening of the temperature mixing damper is adjusted according to the target temperature of each temperature zone to obtain the actual temperature of each temperature zone, including: 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 front row mixing damper of the vehicle, which is used to adjust the mixing ratio of hot and cold air in the left and right temperature zones of the front row to achieve the target temperature set by the occupants. The second temperature mixing damper refers to the rear row mixing damper of the vehicle, which is used to adjust the mixing ratio of hot and cold air in the left and right temperature zones of the rear row.

[0077] In a specific implementation, the opening of the front row mixing damper of the vehicle is adjusted according to the temperature requirements of the left and right temperature zones of the front row, and the actual temperatures of the left and right temperature zones of the front row after the adjustment, i.e., the first actual temperature and the second actual temperature, are collected to ensure that the adjustment result meets the target value set by the occupant. Similarly, the opening of the rear row mixing damper of the vehicle is adjusted according to the target temperature requirements of the left and right temperature zones of the rear row, and the actual temperatures of the left and right temperature zones of the rear row after the adjustment, i.e., the third actual temperature and the fourth actual temperature, 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 distribution of hot and cold air in the front and rear rows of the four-temperature zone. The air is sucked in through the internal circulation air inlet and the external circulation air inlet and transmitted to the blower. The air is driven by the blower and sent into the vehicle's air conditioning system. In the air conditioning system, the air first passes through the filter to remove dust and impurities to ensure that the air sent into the car is clean. Then, the air is divided into four routes, one entering the front row mixing air door and the other entering the rear row mixing air door to generate front row cold air and rear row cold air respectively. The other two routes enter the heater core respectively to generate front row warm air and rear row warm air. In the heater core, the coolant exchanges heat with the air through the radiator to heat the air.

[0079] like Figure 3 As shown, Figure 3 This is a schematic diagram of the cold and hot air mixing and wind direction distribution of the four-temperature zone air conditioner. The front row cold air and the front row hot air are respectively passed through two front row temperature mixing dampers, and then mixed according to the target temperature set by the passengers. The mixed air is controlled by the front row air volume control damper, and then distributed to the left and right air outlets of the front row through the front row left and right air volume distribution dampers. The rear row cold air and the rear row hot air enter the rear row temperature mixing damper respectively, and are mixed according to the target temperature set by the rear row passengers. The mixed air is controlled by the rear row air volume control damper, and then distributed to the left and right air outlets of the rear row through the rear row left and right air volume distribution dampers.

[0080] Step S30, 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, the damper motor movement strategy of the corresponding temperature zone is determined according to the target exhaust volume gear of each temperature zone.

[0081] It should be noted that when the actual exhaust air volume level of each temperature zone is consistent with the target exhaust air 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 corresponding damper motor movement plans according to the target exhaust volume gear of each temperature zone, adjusting the engine speed at a suitable speed, thereby 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, noise environments in different scenarios will appear. When the air volume control damper moves, the running 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, showing 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 the motor noise of the damper movement. Therefore, during the damper adjustment process, it is necessary to distinguish between the high and low gears of the air volume. In the low gear, the wind noise is small, and the motor needs to move quickly to the designed position. In the 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 it can cover 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 motion 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 motion strategy.

[0085] It should be noted that the first preset gear can be the 3rd gear, and the second preset gear can be the 5th gear. This embodiment does not impose specific restrictions on this. This embodiment takes the 3rd gear and the 5th gear as examples for explanation. At the exhaust volume gear of 3rd gear 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 detected by the passengers. Therefore, the movement of the damper motor needs to quickly execute the designed target speed, that is, the first motion strategy is a fast motion strategy. At the 5th gear and above, the wind noise background noise of the entire air-conditioning system is very large, and the movement of the damper motor is not easily detected 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 to the designed target speed silently, that is, the second motion strategy is a slow motion strategy. Through this strategy, it can be ensured that under different air volume gears, the movement of the damper motor and the change of 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 movement strategy includes a fast movement strategy and a slow movement strategy. According to the corresponding movement strategy, the speed of the damper motor at each temperature can be controlled to switch quickly or slowly. Under the fast movement strategy, the damper motor speed will quickly increase to the target speed to meet the needs of the low air volume gear, ensure that the damper quickly reaches the designed position, and reduce the occupants' perception of motor noise. Under the slow movement strategy, the damper motor speed will gradually increase to avoid drastic changes in wind noise, so that the movement of the damper motor and the change in wind noise are coordinated with each other, thereby achieving noise control.

[0088] The present embodiment provides a vehicle air-conditioning noise control method, which first responds to occupant request instructions for different temperature zones, 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 the first to fourth temperature zones; performs damper control 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, determines a damper motor motion strategy for the corresponding temperature zone according to the target exhaust volume gear of each temperature zone; adjusts the damper motor speed for the corresponding temperature zone 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, the present embodiment determines the target exhaust volume gear and target temperature of each temperature zone according to the occupant request instructions of different temperature zones and performs damper control; when the air volume gear and temperature are adjusted to meet the demand, the damper motor movement strategy is determined according to the exhaust volume gear 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, thus overcoming the problem that different mechanical structures will generate certain noise when they start to operate, and different air volume distribution will create different sound fields, resulting in different temperature zones having their own air-conditioning noise, which affects the technical defect of user experience. The air-conditioning noise of different temperature zones can be effectively controlled and the air-conditioning sound quality can be improved.

[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-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 4 , the step S40 further includes steps S401-S403:

[0091] Step S401 , determining the target speed of the damper motor for each temperature zone according to the target exhaust air volume level of each temperature zone and the correlation between the exhaust air 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 the best match between the damper motor speed and the exhaust volume at different exhaust volume gears, thereby achieving a balance between noise control and air volume distribution.

[0093] In a feasible implementation, before step S401, it may also include: collecting motor noise at different damper motor speeds and wind noise at different exhaust volume gears; determining the correlation between wind noise parameters and motor noise parameters according to the motor noise at different damper motor speeds and the wind noise at different exhaust volume gears; determining the correlation between exhaust volume gear and damper motor speed according to 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., and 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, which includes the sound quality parameters of the motor speed and the motor noise. The motor speed includes V1, V2, V3, etc., and the sound quality parameters of the motor noise include sound pressure level, sharpness and loudness.

[0100]

[0101] It is worth noting that at low gear, the wind noise is small, and the motor needs to move quickly to the designed position. At 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. The parameter correlation between the various wind noise parameters and the motor noise is: wind noise at a certain gear - motor noise>-1. According to the parameter correlation between the various wind noise parameters and the motor noise, the correlation between the specific gear and the motor movement speed can be obtained. Since the noise characteristics of each blower are very different, the running speed of the damper motor at different gears is also very different.

[0102] like Figure 5 As shown, Figure 5 This is a relationship diagram between the air conditioning gear position 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 position, the slower the air volume damper movement speed. When it 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, the slower the mixing damper movement speed. When it 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, adjusting the damper motor speed of the corresponding temperature zone 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 respectively 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 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. 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, so 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, adjusting the damper motor speed of the corresponding temperature zone to the damper motor target speed according to the second motion strategy.

[0108] It should be noted that the second motion strategy is a slow motion strategy. Under the slow motion strategy, the speed of the damper motor needs to be adjusted smoothly and gradually to avoid abrupt changes in wind noise and exposure of motor movement noise. Especially in high gears, due to the increase in wind noise, the slow motion strategy can take advantage of the natural masking effect of wind noise, making the sound of motor movement less obvious, thereby improving the comfort of the vehicle interior environment.

[0109] In the specific implementation, if the four passenger positions request 8-speed wind at 18℃ on the left side of the front row, 7-speed wind at 20℃ on the right side of the front row, 8-speed wind at 17℃ on the left side of the rear row, and 6-speed wind at 20℃ on 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 execute the movement silently 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 strategies in different temperature zones, the changes of 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.
