Description

Technical Field

[0001] The present invention relates to the field of automobile control technology, and in particular to a method, system, terminal, vehicle and storage medium for starting noise reduction of an in-vehicle air conditioner. Background Art

[0002] With the acceleration of the process of automobile intelligence, modern vehicles have gradually evolved into a multifunctional mobile space that integrates travel, lunch breaks and even travel and living. Therefore, it is particularly important to create a low-noise, high-comfort in-car environment for passengers. However, the use of air conditioning in the automotive thermal management system, especially the frequent operation and large air volume output in high temperature environments, inevitably produces significant wind noise, which poses a challenge to the passengers' riding experience. It is particularly noteworthy that the intelligent thermal management control system of many vehicles can automatically adjust the air volume according to demand, resulting in frequent changes in the air outlet noise. This fluctuation in sound frequency is not only easy to detect, but may also distract the driver's attention and threaten driving safety. At the same time, it also seriously interferes with the quality of passengers' rest in rest mode, reducing the overall experience.

[0003] In response to the above problems, although existing technologies such as patent CN114822470A propose a method, system, terminal and storage medium based on vehicle-mounted holographic noise reduction air conditioning, which collects environmental noise in real time and generates noise-cancelling audio to perform sound field superposition noise reduction. However, this method relies on the microphone to collect noise, and there is a time lag problem. Specifically, the microphone can only capture the signal after the noise is generated, and the time loss of processor processing and audio output causes the noise reduction effect to be unable to immediately cover the moment when the noise starts, which has certain limitations.

[0004] Therefore, it is necessary to develop a new method, system, terminal, vehicle and storage medium for starting noise reduction of in-vehicle air conditioning. Summary of the invention

[0005] The purpose of the present invention is to provide a method, system, terminal, vehicle and storage medium for reducing noise when starting an air conditioner in a vehicle, so as to solve the problem that the air outlet cannot be quickly silenced when it is started.

[0006] In a first aspect, a method for reducing noise during startup of an in-vehicle air conditioner according to the present invention comprises the following steps: In response to detecting an air-conditioning start command, calculating a target air volume level and a target air door position; Determine the anti-phase noise reduction frequency signal according to at least the target air volume gear and the target air door position; The anti-phase noise reduction audio signal is played during the startup of the air conditioner to eliminate or reduce the noise generated by the startup of the air conditioner.

[0007] Optionally, the step of determining the anti-phase noise reduction frequency signal at least according to the target air volume gear and the target air door position is specifically as follows: According to the target air volume gear and the target air door position, a first noise reduction table is searched to determine the anti-phase noise reduction frequency signal; The first noise reduction table includes the correspondence between the target air volume level, the target damper position and the anti-phase noise reduction audio signal. Through the pre-established first noise reduction table, the system can quickly find the corresponding anti-phase noise reduction audio signal according to the calculated target air volume level and the target damper position.

[0008] Optionally, before determining the anti-phase noise reduction audio signal, the air outlet position of the temperature zone is calculated; According to the target air volume gear, the target air door position and the temperature zone air outlet position, the second noise reduction table is searched to determine the anti-phase noise reduction frequency signal; Among them, the second noise reduction table includes the correspondence between the target air volume gear, the target damper position, the temperature zone air outlet position and the anti-phase noise reduction frequency signal. For vehicles with divided temperature zones, the air outlet positions of different temperature zones may affect the distribution and characteristics of the noise. By considering the temperature zone air outlet position, the system can more accurately identify and respond to noise sources in different areas, thereby providing a more personalized noise reduction experience. Passengers can adjust the temperature zone air outlet position according to their needs while enjoying the best noise reduction effect. Querying the second noise reduction table in combination with the three parameters of target air volume gear, target damper position and temperature zone air outlet position can ensure that the generated anti-phase noise reduction frequency signal is more in line with the actual noise environment. This multi-dimensional matching method can cover the noise sources more comprehensively and improve the pertinence and effectiveness of noise reduction.

[0009] Optionally, the calculation of the target air volume gear and the target air door position is specifically as follows: Obtain the current ambient temperature, current vehicle interior temperature, and thermal management requirements; The target air volume level and target damper position are calculated based on the current ambient temperature, the current in-car temperature, and thermal management requirements. By sensing the ambient temperature, in-car temperature, and thermal management requirements in real time, the system can automatically calculate the most suitable air volume level and damper position to meet the passengers' needs for in-car temperature comfort.

[0010] Optionally, it also includes: Collect noise signals from the passenger compartment in real time; Determining whether the decibel value of the noise signal is greater than a preset decibel threshold; If yes, then modifying the anti-phase noise reduction audio signal based on the noise signal until the decibel value of the noise signal is less than or equal to a preset decibel threshold, thereby obtaining a modified anti-phase noise reduction audio signal; The corrected anti-phase noise reduction audio signal is played. By collecting the noise signal in the passenger compartment in real time, the system can instantly perceive the change of noise. When the decibel value of the noise signal exceeds the preset decibel threshold, the system can automatically start the correction mechanism and dynamically adjust the anti-phase noise reduction audio signal. This dynamic adaptability ensures that the noise reduction effect can be continuously maintained in the best state and effectively cope with various sudden noise situations.

[0011] In a second aspect, a system for implementing the in-vehicle air conditioning startup noise reduction method according to the present invention comprises: A calculation module, used to calculate the target air volume gear and the target air door position when an air-conditioning start command is detected; A processing module, configured to determine an anti-phase noise reduction frequency signal according to at least a target air volume gear and a target air door position; The execution module is used to play the anti-phase noise reduction audio signal during the startup process of the air conditioner.

[0012] Optionally, it also includes: A collection module, used for collecting noise signals of the passenger compartment; The correction module is used to correct the anti-phase noise reduction audio signal based on the noise signal when it is determined that the decibel value of the noise signal is greater than the preset decibel threshold, until the decibel value of the noise signal is less than or equal to the preset decibel threshold, thereby obtaining a corrected anti-phase noise reduction audio signal. Correcting the anti-phase noise reduction audio signal based on the real-time noise signal can ensure that the noise reduction audio signal is optimally matched with the current noise signal in terms of phase, frequency and amplitude. This precise matching can more effectively offset noise, improve the noise reduction effect, and make the passenger cabin quieter and more comfortable.

[0013] In a third aspect, a terminal described in the present invention includes a memory and a controller, wherein the memory stores a computer-readable program, and when the computer-readable program is called by the controller, it can execute the steps of the in-vehicle air conditioning startup noise reduction method described in the present invention.

[0014] In a fourth aspect, a vehicle described in the present invention adopts the in-vehicle air-conditioning startup noise reduction control system described in the present invention.

[0015] In a fifth aspect, a storage medium described in the present invention stores a computer-readable program therein, and when the computer-readable program is called, it can execute the steps of the in-vehicle air conditioning startup noise reduction method described in the present invention.

[0016] Beneficial effects of the present invention: The in-vehicle air conditioning startup noise reduction method proposed in the present invention can accurately generate and instantly play the anti-phase noise reduction audio signal by intelligently predicting the target air volume gear and air door position when the air conditioner is turned on. This method not only significantly shortens the response time of the noise reduction system, but also greatly improves the noise reduction accuracy, and effectively solves the problem that the air outlet noise is rapid and difficult to eliminate instantly when the air conditioner is started. Compared with the limitations of traditional noise reduction that only relies on mechanical structure optimization, the present invention realizes the intelligent and efficient application of active noise reduction technology, providing users with a quieter and more comfortable driving environment.

DETAILED DESCRIPTION

[0018] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0019] Embodiment 1 like Figure 1As shown, in an embodiment of the present application, a method for reducing noise when starting an air conditioner in a vehicle includes the following steps: In response to detecting an air-conditioning-on command, a target air volume level and a target air door position are calculated.

[0020] The anti-phase noise reduction frequency signal is determined according to the target air volume gear and the target air door position.

[0021] During the startup of the air conditioner, an anti-phase noise reduction audio signal is played to eliminate or reduce the noise generated by the startup of the air conditioner.

[0022] In a possible embodiment, the anti-phase noise reduction frequency signal is determined at least according to the target air volume gear and the target air door position, specifically: The first noise reduction table is queried according to the target air volume gear and the target damper position to determine the anti-phase noise reduction frequency signal; wherein the first noise reduction table includes the correspondence between the target air volume gear, the target damper position and the anti-phase noise reduction frequency signal.

[0023] In the embodiment of the present application, the first noise reduction table is obtained by experiment, and the first noise reduction table is established by collecting the air volume gear enable signal output by the thermal management controller and the target air door position information for use by the in-vehicle air conditioning startup noise reduction system. This makes up for the shortcomings of the existing acquisition module 4 (such as: microphone) inaccurate collection. Through the pre-established first noise reduction table, the system can quickly find the corresponding anti-phase noise reduction audio signal based on the calculated target air volume gear and target air door position.

[0024] like Figure 7 As shown in the figure, as a specific example, the steps to establish the first noise reduction table are mainly to first build an experimental environment, which needs to meet the requirements of no other noise source input, the noise audio collection accuracy meets the standard and necessary filtering processing is performed, and the pickups used for collection are located at the head positions of the front and rear seats respectively. During the collection process, the variables are arranged and combined with the air conditioner air outlet position and the air door adjustment position as double variables. After completing the above data collection, it is integrated into a database for table lookup, and the first noise reduction table is obtained.

[0025] In a possible embodiment, the target air volume level and the target air door position are calculated as follows: Obtain the current ambient temperature, current in-car temperature, and thermal management requirements; calculate the target air volume level and target damper position based on the current ambient temperature, current in-car temperature, and thermal management requirements. By sensing the ambient temperature, in-car temperature, and thermal management requirements of the vehicle in real time, the system can automatically calculate the most appropriate target air volume level and target damper position to meet the passengers' needs for in-car temperature comfort.

[0026] As a specific example, the computing module 1 may adopt the thermal management controller on the vehicle, and the processing module 2 may adopt the ANC controller on the vehicle (existing vehicles have an ANC controller (i.e., active noise reduction controller)). This system can directly use the thermal management controller and the ANC controller without increasing the hardware cost of the entire vehicle.

[0027] When the air conditioner is turned on, first determine whether the user has turned on the silent mode. If not, end the process. If so (that is, after receiving the command to turn on the air conditioner), the thermal management controller comprehensively determines and outputs the compressor target speed, the switches of various valves, the target damper position, and the target air volume gear according to the current ambient temperature, the current temperature in the car, and the thermal management requirements. Among them, the factors that most affect the noise at the air outlet are the target damper position and the target air volume gear. Both types of real-time information are calculated by the thermal management controller and output to the bus or IO port to control the relevant actuators. Therefore, the thermal management controller can send this type of status information to the ANC controller in real time for sharing. The ANC controller can accurately predict the noise information of the air outlet by receiving the target damper position and target air volume gear information sent by the thermal management controller, and determine the anti-phase noise reduction audio signal according to the target air volume gear and the target damper position. At the same time, the reaction time of the actuator to complete the air supply action can also offset the execution time of playing the noise reduction audio, so as to achieve the purpose of synchronous elimination.

[0028] As a specific example, the command to turn on the air conditioner is manually input by the customer through the human-computer interaction module, or functions such as automatic defogger are automatically turned on.

[0029] As a specific example, a vehicle-mounted speaker is used to play an anti-phase noise reduction audio signal. The vehicle-mounted speaker can be arranged on the door panel, seat headrest, or roof to achieve the best scene surround effect and minimize the interference of noise to the passengers.

[0030] As a specific example, a microphone is used to collect noise signals in the passenger compartment. The microphone is generally installed above the passenger's head. Since the propagation of sound waves in the car will be affected by distance and interior reflection, the best position of the microphone should be close to the passenger's head, and microphones should be installed in the front and rear rows for sound collection.

[0031] As a specific example, a method for reducing noise when starting an air conditioner in a vehicle specifically includes the following steps: Step 1: Select the passenger compartment cooling mode through the human-computer interaction interface, and upload the mode command to the vehicle controller for conditional judgment. If the conditions are met, the mode state will be sent to the thermal management controller for conditional judgment.

[0032] Step 2: After the thermal management controller makes a conditional judgment on the mode status, it calculates whether each component of the air-conditioning assembly is enabled and the working target parameters, including the calculation of the target air volume gear and the target damper position (that is, when the air-conditioning start command is detected, the target air volume gear and the target damper position are calculated), and the target air volume gear and the target damper position signals are sent to the CAN bus.

[0033] Step three, the ANC controller receives the target air volume gear and target air door position signals on the CAN bus, searches the first noise reduction table with the target air volume gear and target air door position, obtains the anti-phase noise reduction audio signal corresponding to the target air volume gear and target air door position, and outputs the anti-phase noise reduction audio signal to the vehicle speaker.

[0034] Step 4: The vehicle speaker plays the anti-phase noise reduction audio signal.

[0035] When the air conditioner is started, the air conditioning noise reduction in the car is taken over by the original ANC controller and the original active noise reduction algorithm on the vehicle.

[0036] like Figure 5 As shown, in an embodiment of the present application, a vehicle air conditioning startup noise reduction system includes a calculation module 1, a processing module 2 and an execution module 3, wherein the calculation module 1 is connected to the processing module 2, and the processing module 2 is connected to the execution module 3. The calculation module 1 is used to calculate the target air volume gear and the target air door position when the air conditioning start-up instruction is detected. The processing module 2 is used to determine the anti-phase noise reduction audio signal based on at least the target air volume gear and the target air door position. The execution module 3 is used to play the anti-phase noise reduction audio signal during the startup process of the air conditioner.

[0037] like Fig. 9 As shown, in an embodiment of the present application, a terminal includes a memory 6 and a controller 7, and the memory 6 stores a computer-readable program. When the computer-readable program is called by the controller 7, it can execute the steps of the in-vehicle air conditioning startup noise reduction method as described in the embodiment of the present application.

[0038] In an embodiment of the present application, a vehicle adopts the in-vehicle air conditioning startup noise reduction control system as described in the embodiment of the present application.

[0039] In an embodiment of the present application, a storage medium stores a computer-readable program, which, when called, can execute the steps of the in-vehicle air conditioning startup noise reduction method as described in the embodiment of the present application.

[0040] In an embodiment of the present application, the storage medium may be a tangible storage medium that may contain or store a program for use by or in conjunction with an instruction execution system, device, or equipment. The storage medium may be a machine-readable signal storage medium or a machine-readable storage medium. The storage medium may include, but is not limited to, electronic, magnetic, optical, electromagnetic, infrared, or semiconductor systems, devices, or equipment, or any suitable combination of the foregoing. More specific examples of storage media may include electrical connections based on one or more lines, portable computer disks, hard disks, random access memories (RAM), read-only memories (ROM), erasable programmable read-only memories (EPROM or flash memory), optical fibers, portable compact disk read-only memories (CD-ROM), optical storage devices, magnetic storage devices, or any suitable combination of the foregoing.

[0041] Embodiment 2 like Figure 2 As shown, for vehicles with temperature zones (also called zoned air conditioning, which refers to the function of independently adjusting the air conditioning temperature in different areas of the vehicle. This design is intended to meet the different temperature requirements of different passengers and improve driving comfort), the air outlet positions of different temperature zones may affect the distribution and characteristics of noise. For such vehicles, an embodiment of the present application provides a method for reducing noise when starting the air conditioner in the vehicle, comprising the following steps: When an air-conditioning start command is detected, the target air volume level, target damper position and temperature zone air outlet position are calculated.

[0042] The anti-phase noise reduction frequency signal is determined according to the target air volume gear, the target air door position and the air outlet position of the temperature zone.

[0043] During the startup of the air conditioner, an anti-phase noise reduction audio signal is played to eliminate or reduce the noise generated by the startup of the air conditioner.

[0044] In addition to considering the target air volume gear and the target air door position, this method also considers the air outlet position of the temperature zone. For vehicles with temperature zones, it can more accurately identify and respond to noise sources in different areas, thereby providing a more personalized noise reduction experience. At the same time, passengers can adjust the air outlet position of the temperature zone according to their own needs and enjoy the best noise reduction effect.

[0045] In a possible embodiment, the anti-phase noise reduction frequency signal is determined according to the target air volume gear, the target air door position and the temperature zone air outlet position, specifically: The second noise reduction table is queried according to the target air volume gear, target damper position and temperature zone outlet position to determine the anti-phase noise reduction frequency signal. The second noise reduction table includes the correspondence between the target air volume gear, target damper position, temperature zone outlet position and the anti-phase noise reduction frequency signal. Querying the second noise reduction table in combination with the three parameters of target air volume gear, target damper position and temperature zone outlet position can ensure that the generated anti-phase noise reduction frequency signal is more in line with the actual noise environment. This multi-dimensional matching method can cover the noise source more comprehensively and improve the pertinence and effectiveness of noise reduction.

[0046] like Figure 8 As shown in the figure, as another specific example, the steps to establish the second noise reduction table are mainly to first build an experimental environment, which needs to meet the requirements of no other noise source input, the noise audio collection accuracy meets the standard and necessary filtering processing is performed, and the microphones used for collection are located at the head positions of the front and rear seats respectively. During the collection process, the variables are arranged and combined with the air conditioner air outlet position, the air door adjustment position, and the temperature zone air outlet position as three variables. After completing the above data collection, it is integrated into a database that can be looked up, and the second noise reduction table is obtained.

[0047] For vehicles with different temperature zones, in addition to the target damper position and target air volume gear, the main factors affecting the air outlet noise also include the air outlet position information of the temperature zone. These three types of real-time information are calculated by the thermal management controller and output to the bus or IO port to control the relevant actuators. Therefore, the thermal management controller can send this type of status information to the ANC controller in real time for sharing. The ANC controller can more accurately predict the noise information of the air outlet by receiving the target damper position, target air volume gear and air outlet position information of the temperature zone sent by the thermal management controller. At the same time, the reaction time of the actuator to complete the air supply action can also offset the execution time of playing the noise reduction audio, thereby achieving the purpose of synchronous elimination.

[0048] As a specific example, a method for reducing noise when starting an air conditioner in a vehicle specifically includes the following steps: Step 1: Select the passenger compartment cooling mode through the human-computer interaction interface, and upload the mode command to the vehicle controller for conditional judgment. If the conditions are met, the mode state will be sent to the thermal management controller for conditional judgment.

[0049] Step 2: After the thermal management controller makes a conditional judgment on the mode status, it calculates whether each component of the air-conditioning assembly is enabled and the working target parameters, including the target air volume gear, target damper position and temperature zone air outlet position calculation (that is, when the air-conditioning start command is detected, the target air volume gear, target damper position and temperature zone air outlet position are calculated), and the target air volume gear, target damper position signal and temperature zone air outlet position are sent to the CAN bus.

[0050] Step three, the ANC controller receives the target air volume gear, target air door position and temperature zone air outlet position on the CAN bus, and queries the second noise reduction table according to the target air volume gear, target air door position and temperature zone air outlet position, obtains the anti-phase noise reduction audio signal corresponding to the target air volume gear, target air door position and temperature zone air outlet position, and outputs the anti-phase noise reduction audio signal to the vehicle speaker.

[0051] Step 4: The vehicle speaker plays the anti-phase noise reduction audio signal.

[0052] The rest is the same as that of the first embodiment.

[0053] Embodiment 3 like Figure 3 and Figure 4 As shown, in an embodiment of the present application, a method for starting noise reduction of an air conditioner in a vehicle also includes: real-time acquisition of noise signals in the passenger compartment. Determine whether the decibel value of the noise signal is greater than a preset decibel threshold; if so, correct the anti-phase noise reduction audio signal based on the noise signal until the decibel value of the noise signal is less than or equal to the preset decibel threshold, and obtain the corrected anti-phase noise reduction audio signal. Play the corrected anti-phase noise reduction audio signal. By real-time acquisition of noise signals in the passenger compartment, the system can instantly perceive changes in noise. When the decibel value of the noise signal exceeds the preset decibel threshold, the system can automatically start a correction mechanism (the correction mechanism belongs to conventional technical means in this field, so it will not be repeated here) to dynamically adjust the anti-phase noise reduction audio signal. This dynamic adaptability ensures that the noise reduction effect can continue to be maintained in the best state and effectively cope with various sudden noise situations.

[0054] like Figure 6 As shown, in a possible embodiment, a vehicle air conditioning startup noise reduction system also includes an acquisition module 4 and a correction module 5, wherein the acquisition module 4 is connected to the correction module 5, and the correction module 5 is connected to the processing module 2. The acquisition module 4 is used to collect the noise signal of the passenger compartment. The correction module 5 is used to correct the anti-phase noise reduction audio signal based on the noise signal when it is determined that the decibel value of the noise signal is greater than the preset decibel threshold, until the decibel value of the noise signal is less than or equal to the preset decibel threshold, so as to obtain the corrected anti-phase noise reduction audio signal. Correcting the anti-phase noise reduction audio signal based on the real-time noise signal can ensure that the noise reduction audio signal is optimally matched with the current noise signal in terms of phase, frequency and amplitude. This precise matching can more effectively offset noise, improve the noise reduction effect, and make the passenger compartment quieter and more comfortable.

[0055] The rest is the same as that of the first or second embodiment.

[0056] The above-mentioned embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above-mentioned embodiments. Any other changes, modifications, substitutions, combinations and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement modes and shall be included in the protection scope of the present invention.
