Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more specifically, to a method and apparatus for controlling the damper of a vehicle, a storage medium, and an electronic device. Background Technology

[0002] With the development of new energy vehicles, users' expectations for cabin comfort have evolved from single-zone constant temperature to dual-zone independent temperature control. Currently, dual-zone air conditioning systems regulate the air outlet temperature through independent left and right mixing dampers. However, since both sides share a heater core, changes in damper opening alter the total airflow and resistance through the core, creating a flow field coupling effect. Improper control can easily lead to system pressure fluctuations, compressor protection, or oscillations, affecting comfort and reliability.

[0003] In related technologies, when controlling the opening of the damper, fixed threshold control is often used directly, that is, fixed compressor speed threshold and damper opening limit are used. This makes it impossible to adaptively select the corresponding control parameters according to the target temperature of the temperature control zone, resulting in a significant decrease in control accuracy.

[0004] Therefore, improving the accuracy of vehicle damper control to enhance the comfort and reliability of vehicle air conditioning systems has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a vehicle damper control method and device, storage medium, electronic device, and computer program product to at least solve the problem in related technologies where the control parameters cannot be adaptively selected according to the target temperature of the temperature control zone, resulting in a significant decrease in control accuracy.

[0007] According to another aspect of the embodiments of this application, a vehicle damper control device is also provided, comprising: an acquisition module, configured to acquire vehicle parameters when the vehicle is in heating mode; wherein the vehicle parameters include: a first target temperature of a first temperature control zone of the vehicle, and a second target temperature of a second temperature control zone of the vehicle; the first target temperature is greater than the second target temperature; a determination module, configured to determine the temperature difference between the first target temperature and the second target temperature, and compare the temperature difference with a preset temperature threshold to obtain a first comparison result; the temperature threshold includes: a first temperature threshold and a second temperature threshold, the first temperature threshold being less than the second temperature threshold; a first control... The first control module is configured to determine the vehicle's damper control mode as a first control mode when the first comparison result indicates that the temperature difference is less than the first temperature threshold, and to determine a first damper control parameter matching the first control mode, and to control the damper opening of the first temperature control zone and the second temperature control zone based on the first damper control parameter; the second control module is configured to determine the vehicle's damper control mode as a second control mode when the first comparison result indicates that the temperature difference is greater than the second temperature threshold, and to determine a second damper control parameter matching the second control mode, and to control the damper opening of the first temperature control zone and the second temperature control zone based on the second damper control parameter.

[0008] According to another aspect of the embodiments of this application, a computer-readable storage medium is also provided, wherein a computer program is stored in the computer-readable storage medium, and the computer program is configured to execute the above-described vehicle damper control method when running.

[0010] According to another aspect of the embodiments of this application, a computer program product is also provided, including a computer program that, when executed by a processor, implements the steps of the methods described in various embodiments of this application.

[0011] In this embodiment, when the vehicle is in heating mode, vehicle parameters are acquired. These parameters include a first target temperature in the first temperature control zone and a second target temperature in the second temperature control zone. Since the first target temperature is greater than the second target temperature, the temperature difference between the first and second target temperatures is compared with a temperature threshold. If the first temperature threshold is less than the second temperature threshold, and the temperature difference is small (i.e., less than the first temperature threshold), a first damper control parameter matching the first control mode is determined. The damper opening of the first and second temperature control zones is controlled based on the first damper control parameter. Conversely, if the temperature difference is large (i.e., greater than the second temperature threshold), a second damper control parameter matching the second control mode is determined. The damper opening of the first and second temperature control zones is controlled based on the second damper control parameter. This allows for refined and differentiated control under different control modes, effectively improving the accuracy of the vehicle's damper control. Attached Figure Description

[0026] To address the aforementioned problems, this embodiment provides a vehicle damper control method, applied to electronic devices, referencing... Figure 2 The diagram shows a flowchart of a vehicle damper control method, which includes the following steps S202-S208:

[0027] Step S202: When the vehicle is in heating mode, acquire the vehicle parameters; wherein, the vehicle parameters include: the first target temperature of the first temperature control zone of the vehicle, and the second target temperature of the second temperature control zone of the vehicle; the first target temperature is greater than the second target temperature.

[0028] It should be noted that when the vehicle is in heating mode, firstly, vehicle parameters are acquired in real time. These parameters may include: a first target temperature for the first temperature control zone (e.g., the driver's side) and a second target temperature for the second temperature control zone (e.g., the passenger's side). Based on user preferences, the first target temperature may be higher than the second target temperature. Based on the acquired first and second target temperatures, the temperature difference between the two temperature control zones can be calculated. This temperature difference reflects the degree of difference in independent temperature control requirements between the two zones.

[0029] Step S204: Determine the temperature difference between the first target temperature and the second target temperature, compare the temperature difference with a preset temperature threshold, and obtain a first comparison result; the temperature threshold includes: a first temperature threshold and a second temperature threshold, wherein the first temperature threshold is less than the second temperature threshold.

[0030] Specifically, the difference between the first target temperature and the second target temperature can be calculated, reflecting the difference in demand between the two temperature zones. This temperature difference is compared with preset first and second temperature thresholds, where the second threshold is greater than the first. The comparison result is categorized into three states: when the temperature difference is less than the first temperature threshold, it is determined to be a small temperature difference condition, triggering the first control mode; when the temperature difference is greater than the second temperature threshold, it is determined to be a large temperature difference condition, triggering the second control mode; when the temperature difference is equal to or equal to the first or second temperature threshold, or falls between the first and second temperature thresholds, the original mode remains unchanged. This dual-threshold design effectively prevents frequent mode switching in the critical range, improving control stability.

[0031] Optionally, before comparing the temperature difference with a preset temperature threshold to obtain the first comparison result, the vehicle's damper control method further includes: acquiring a temperature reference value, a temperature offset, and a hysteresis temperature difference; determining a second temperature threshold based on the sum of the temperature reference value and the temperature offset; and determining a first temperature threshold based on the difference between the second temperature threshold and the hysteresis temperature difference. It can be understood that acquiring the temperature reference value, temperature offset, and hysteresis temperature difference; using the sum of the temperature reference value and the temperature offset to determine the second temperature threshold (cut-off threshold), which can be adaptively adjusted according to the load or environment to ensure timely intervention under large temperature difference conditions; and then subtracting the hysteresis temperature difference from the second temperature threshold to determine the first temperature threshold (hysteresis threshold). This forms a hysteresis range, effectively preventing frequent mode switching caused by temperature fluctuations near the critical point, and improving system stability.

[0032] Optionally, the formulas for determining the first temperature threshold and the second temperature threshold are shown below:

[0033] = + ; = - ;

[0034] in, The second temperature threshold is the positive temperature difference threshold for the vehicle system to switch from sleep / low power mode to high load / active temperature control mode, and it is the initiation condition for state switching. This refers to the temperature reference value, i.e., the basic allowable temperature difference (which can be determined by operating conditions, device temperature resistance, and user requirements). This refers to the temperature offset, also known as the temperature compensation offset (which can be corrected based on load, ambient temperature, and aging). The first temperature threshold is the maintenance threshold for not immediately switching back to the original control mode. It is the lower temperature difference for mode maintenance and prevention of repeated switching, satisfying the hysteresis (hysteresis loop) characteristic. Hysteresis temperature difference, or hysteresis width, is a fixed design value. >0; In this way, the two thresholds form a hysteresis interval, dividing the system into three partitions to realize the state machine logic decision.

[0035] Step S206: If the temperature difference indicated by the first comparison result is less than the first temperature threshold, determine that the vehicle's damper control mode is the first control mode, and determine the first damper control parameters that match the first control mode. Control the damper opening of the first temperature control zone and the second temperature control zone based on the first damper control parameters.

[0036] In an exemplary embodiment, the vehicle parameters further include: compressor speed and ambient temperature; determining the first damper control parameter matching the first control mode includes: comparing the compressor speed with a dynamic speed threshold to obtain a second comparison result; the dynamic speed threshold includes: a first speed threshold and a second speed threshold; the first speed threshold is less than the second speed threshold; if the second comparison result indicates that the compressor speed is less than the first speed threshold, it is determined that the vehicle's compressor is in a low-load condition, and the first damper control parameter is determined based on the ambient temperature and a first ambient temperature slope coefficient and a first ambient temperature intercept coefficient associated with the low-load condition; if the second comparison result indicates that the compressor speed is greater than the second speed threshold, it is determined that the vehicle's compressor is in a high-load condition, and the first damper control parameter is determined based on the ambient temperature and a second ambient temperature slope coefficient and a second ambient temperature intercept coefficient associated with the high-load condition; if the second comparison result indicates that the compressor speed is greater than or equal to the first speed threshold and less than or equal to the second speed threshold, the first damper control parameter is determined based on the ambient temperature, a first ambient temperature slope coefficient and a first ambient temperature intercept coefficient associated with the low-load condition, and a second ambient temperature slope coefficient and a second ambient temperature intercept coefficient associated with the high-load condition.

[0037] Understandably, in this embodiment, the operating conditions are dynamically divided based on the compressor speed to optimize damper control. First, the compressor speed is compared with a first speed threshold and a second speed threshold. If the compressor speed is lower than the first speed threshold, it is determined to be a low load, and the first damper control parameters are calculated by combining the ambient temperature and the first ambient temperature slope coefficient and the first ambient temperature intercept coefficient associated with the low load condition. If it is higher than the second speed threshold, it is determined to be a high load, and the first damper control parameters are determined using the second ambient temperature slope coefficient and the second ambient temperature intercept coefficient associated with the high load condition. When the compressor speed is greater than or equal to the first speed threshold and less than or equal to the second speed threshold, interpolation or a hybrid calculation is performed using both low and high load coefficients. This segmented and cross-segment interpolation strategy ensures a continuous and smooth change in the first damper control parameters throughout the entire process from low load to high load, avoiding abrupt changes and improving control smoothness.

[0038] Optionally, the following formula is used to calculate the control parameters of the first damper:

[0039] For low-load conditions, the following formula can be used:

[0040] ;

[0041] in, This refers to the control parameters of the first damper under low-load conditions. The first ambient temperature slope coefficient refers to the lower limit ambient temperature slope coefficient of the damper under low load conditions. It is used to indicate the change in the minimum opening of the damper for every 1°C change in ambient temperature under low load conditions. Refers to ambient temperature; The first ambient temperature intercept coefficient, i.e., the lower limit ambient temperature intercept coefficient of the damper under low load, is used to indicate... =0℃, the lower limit of the reference damper opening under low load conditions.

[0042] For high-load operating conditions, the following formula can be used:

[0043] ;

[0044] in, This refers to the control parameters of the first damper under high load conditions. The second ambient temperature slope coefficient refers to the lower limit ambient temperature slope coefficient of the damper under high load conditions. It is used to indicate the change in the minimum opening of the damper for every 1°C change in ambient temperature under high load conditions. Refers to ambient temperature; The second ambient temperature intercept coefficient, i.e., the lower limit ambient temperature intercept coefficient of the damper under high load, is used to indicate... =0℃, the lower limit of the reference damper opening under high load conditions.

[0045] In some embodiments, before comparing the compressor speed with a dynamic speed threshold to obtain a second comparison result, the vehicle's damper control method further includes: obtaining a first speed slope coefficient and a first speed intercept coefficient corresponding to a high-load condition, and obtaining a second speed slope coefficient and a second speed intercept coefficient corresponding to a low-load condition; determining a second speed threshold based on ambient temperature, the first speed slope coefficient, and the first speed intercept coefficient; and determining a first speed threshold based on ambient temperature, the second speed slope coefficient, and the second speed intercept coefficient. The first speed threshold and the second speed threshold are dynamically calculated using ambient temperature to achieve adaptive operation. First, the first speed slope coefficient and the first speed intercept coefficient corresponding to a high-load condition are obtained, as well as the second speed slope coefficient and the second speed intercept coefficient corresponding to a low-load condition. Using ambient temperature and the second speed slope coefficient and the second speed intercept coefficient, a first speed threshold (low-load upper limit) is calculated; using ambient temperature and the first speed slope coefficient and the first speed intercept coefficient, a second speed threshold (high-load lower limit) is calculated. This dynamic calculation based on ambient temperature replaces the fixed threshold, allowing the speed cutoff point to be adjusted in real time with the ambient temperature. This ensures that the compressor load status can be accurately identified under different climatic conditions, laying the foundation for subsequent precise matching of damper control parameters and improving the adaptability of control under all operating conditions.

[0046] Optionally, the formula for determining the second speed threshold is as follows:

[0047] ;

[0048] in, The second speed threshold is used to determine that the heat pump is in full-load heating mode, i.e., high-load mode, when the compressor speed is greater than the second speed threshold. The first speed slope coefficient is used to characterize the change in speed corresponding to the second speed threshold for every 1°C change in ambient temperature. The first speed intercept coefficient is used to characterize the temperature when the ambient temperature is high. The reference high-load speed threshold at 0℃; Refers to ambient temperature.

[0049] Optionally, the formula for determining the first speed threshold is as follows:

[0050] ;

[0051] in, The first speed threshold is used to determine that the heat pump is in a low-load heating condition when the compressor speed is less than the first speed threshold. The second rotational speed slope coefficient is used to characterize the change in rotational speed corresponding to the first rotational speed threshold for every 1°C change in ambient temperature. The second speed intercept coefficient is used to characterize the speed at which the ambient temperature changes. =0℃, reference low-load speed threshold; Refers to ambient temperature.

[0052] Optionally, in the first control mode, the first damper control parameters specifically include: the lower limit of damper opening in the first control mode. Damper control commands can be generated based on the lower limit of damper opening in the first control mode to adjust the damper opening of the first temperature control zone and the second temperature control zone. Since the temperature difference between the first temperature control zone and the second temperature control zone is small, it belongs to the small temperature difference mode. The two temperature control zones can be directly controlled based on the lower limit of damper opening in the first control mode, thus effectively saving computing resources.

[0053] Step S208: If the temperature difference indicated by the first comparison result is greater than the second temperature threshold, determine that the vehicle's damper control mode is the second control mode, and determine the second damper control parameters that match the second control mode. Control the damper opening of the first temperature control zone and the second temperature control zone based on the second damper control parameters.

[0054] In some exemplary embodiments, the vehicle parameters further include: compressor speed, ambient temperature, and heat pump target high pressure; determining the second damper control parameters matching the second control mode includes: determining the first damper control sub-parameter corresponding to the first temperature control zone based on the compressor speed and ambient temperature; determining the second damper control sub-parameter corresponding to the second temperature control zone based on the temperature difference and heat pump target high pressure; the second damper control parameters include: the first damper control sub-parameter and the second damper control sub-parameter.

[0055] It should be noted that, in the second control mode, the first damper control sub-parameters and the second damper control sub-parameters are calculated separately for the first temperature control zone and the second temperature control zone. For the first temperature control zone (high-temperature side), the first damper control sub-parameters are determined based on the compressor speed and ambient temperature to ensure basic heat supply. The specific method for determining the first damper control sub-parameters is the same as that for determining the first damper control parameters, and will not be elaborated in detail in this embodiment. For the second temperature control zone (low-temperature side), the target high pressure of the heat pump and the temperature difference are introduced to calculate the second damper control sub-parameters. The second damper control sub-parameters comprehensively consider the system's heating capacity and temperature difference requirements to accurately suppress the risk of overheating on the low-temperature side. Finally, the first damper control sub-parameters and the second damper control sub-parameters are combined to form the complete second damper control parameters, achieving independent and coordinated fine-grained temperature control for the first and second temperature control zones.

[0056] In some exemplary embodiments, determining the second damper control sub-parameter corresponding to the second temperature control zone based on the temperature difference and the target high pressure of the heat pump includes: inputting the temperature difference and the target high pressure of the heat pump into the formula. Determine the second damper control sub-parameters corresponding to the second temperature control zone; among which, Refers to the second damper control sub-parameter; This refers to the high-voltage term coefficient; The target high pressure of the heat pump; The coefficient of the first-order term of temperature difference; Temperature difference; Refers to the coefficients of the cross-coupling terms; Refers to the basic offset constant.

[0057] It should be noted that the multivariable coupling formula can be used to accurately calculate the control sub-parameters of the second damper. The multivariable coupling formula includes: the high-pressure term ( Temperature difference () ), cross-coupling terms ( ) and basic offset ( Among them, the high-pressure term reflects the vehicle's heating capacity, the temperature difference term reflects the difference in heating and cooling needs, and the cross term solves the shortcomings of a single parameter not being able to match. Through linear combination, the damper opening is made to change smoothly and continuously with pressure and temperature difference. In this way, discrete table lookup can be replaced, parameter jumps can be avoided, and precise temperature control on the low-temperature side under complex operating conditions can be ensured, thereby improving comfort and smoothness.

[0058] In some exemplary embodiments, the second damper control parameters include: a first damper control sub-parameter and a second damper control sub-parameter; controlling the damper opening of the first temperature control zone and the second temperature control zone based on the second damper control parameters includes: generating a first damper opening command based on the first damper control sub-parameter, and controlling the damper opening of the first temperature control zone based on the first damper opening command; generating a second damper opening command based on the second damper control sub-parameter, and controlling the damper opening of the second temperature control zone based on the second damper opening command.

[0059] Specifically, the first and second damper control sub-parameters can be independently converted into execution commands. First, a first damper opening command is generated based on the first damper control sub-parameters and drives the damper in the first temperature control zone (e.g., the high-temperature side) to execute, ensuring sufficient heat supply. Simultaneously, a second damper opening command is generated based on the second damper control sub-parameters and drives the damper in the second temperature control zone (e.g., the low-temperature side) to execute, precisely suppressing overheating. Through independent dual-channel control, differentiated adjustment of the driver and passenger temperature zones is achieved, satisfying personalized comfort needs while avoiding thermal interference to the other zone caused by adjustment of one zone, thus improving overall control accuracy and response speed.

[0060] Through the above steps S202-S208, when the vehicle is in heating mode, vehicle parameters are acquired. These vehicle parameters include: the first target temperature of the first temperature control zone and the second target temperature of the second temperature control zone. If the first target temperature is greater than the second target temperature, the temperature difference between the first and second target temperatures is further compared with a temperature threshold. If the first temperature threshold is less than the second temperature threshold, when the temperature difference is small (i.e., the temperature difference is less than the first temperature threshold), a first damper control parameter matching the first control mode is determined, and the damper opening of the first and second temperature control zones is controlled based on the first damper control parameter. When the temperature difference is large (i.e., the temperature difference is greater than the second temperature threshold), a second damper control parameter matching the second control mode is determined, and the damper opening of the first and second temperature control zones is controlled based on the second damper control parameter. In this way, refined and differentiated control under different control modes can be achieved, effectively improving the accuracy of vehicle damper control.

[0061] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. To better understand the above-described vehicle damper control scheme, in an optional embodiment, a scheme is also provided for explaining and illustrating the above scheme.

[0062] refer to Figure 3 The diagram shown is a flowchart of the vehicle damper control method provided in this application, which specifically includes: power-on initialization; basic enable judgment: that is, judging whether the heating mode of the vehicle's air conditioning is turned on. If yes, the subsequent damper action is initiated; otherwise, the process ends.

[0063] With the vehicle's air conditioning in heating mode, vehicle parameters are acquired, including ambient temperature, compressor speed, first target temperature, and second target temperature. Based on the ambient temperature and compressor speed, dynamic thresholds can be calculated. Further adaptive hysteresis is then applied: the temperature difference is compared with the first and second temperature thresholds to determine whether to enter the first control mode (small temperature difference control), the second control mode (large temperature difference control), or remain unchanged.

[0064] Under small temperature difference control, a unified lower limit for damper opening (i.e., the lower limit for damper opening in the first control mode) is calculated based on the ambient temperature and the compressor's operating speed range. Under large temperature difference control, the high-temperature side is calculated using the same method as for small temperature difference control; the low-temperature side can be calculated based on the temperature difference and the heat pump's target high pressure. Finally, for the lower limits of damper opening in different modes, a limiting process is performed, and the damper opening command is output based on the limited lower limit.

[0065] refer to Figure 4 The diagram shown is a flowchart illustrating the calculation of the lower limit of the damper opening in one embodiment:

[0066] Ambient temperature and compressor speed are obtained. Based on the ambient temperature, dynamic speed thresholds, namely a first speed threshold and a second speed threshold, can be determined. The compressor speed is then compared with these two thresholds to determine the compressor's operating condition, which is used to calculate the lower limit of the damper opening. If the compressor speed is below the first speed threshold, it is considered a low load, and the lower limit of the damper opening is calculated using the ambient temperature and the first ambient temperature slope coefficient and the first ambient temperature intercept coefficient associated with the low load condition. If it is above the second speed threshold, it is considered a high load, and the lower limit of the damper opening is determined using the second ambient temperature slope coefficient and the second ambient temperature intercept coefficient associated with the high load condition. When the compressor speed is greater than or equal to the first speed threshold and less than or equal to the second speed threshold, interpolation or a hybrid calculation is performed using both low and high load coefficients. (Reference) Figure 5 The figure shows a schematic diagram of the dynamic speed threshold changing with ambient temperature: the solid line represents the change of the second speed threshold with ambient temperature, and the dashed line represents the change of the first speed threshold with ambient temperature.

[0067] The following describes in detail the vehicle damper control method provided in this application embodiment, taking into account actual scenarios: For example, in extremely cold and low-load operating conditions, the acquired vehicle parameters include: , , .in, Refers to ambient temperature; This refers to the compressor speed; This refers to the temperature difference; where the first rotational speed threshold is: .because Under low load conditions, the lower limit of the damper opening is: ( At low temperatures, the lower limit of the damper opening automatically increases to 52.5%, ensuring basic heating capacity and preventing a feeling of cold air.

[0068] For example, for high-load operating conditions with large temperature differences, vehicle parameters:

[0069] , , , .

[0070] Calculate the lower limit of damper opening on the low-temperature side: Assumption coefficient .

[0071] If a traditional fixed lower limit (e.g., 50%) is used, hot air will be blown out from the low-temperature side due to excessive heat pump heating. This application calculates 30.8%, allowing the damper to open wider, introducing more cold air for mixing, and accurately maintaining the set temperature on the low-temperature side. (Reference) Figure 6 The figure shows the curve of the lower limit of damper opening as a function of ambient temperature. The dashed line corresponds to the curve of the conventional method, and the solid line corresponds to the curve of this application. In the conventional method, the lower limit of damper opening remains unchanged between different ambient temperatures, such as -20℃ to 0℃ and 10℃ to 30℃; once it crosses -20℃ to 0℃, the lower limit of damper opening changes abruptly (step). In contrast, the curve of this application shows that the lower limit of damper opening is adjusted continuously and in real time with changes in ambient temperature, without any abrupt changes.

[0072] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods according to the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms.

When the temperature difference is large (i.e., greater than the second temperature threshold), a second damper control parameter matching the second control mode is determined, and the damper openings of the first and second temperature control zones are controlled based on this parameter.

Based on the ambient temperature, and the second ambient temperature slope coefficient and the second ambient temperature intercept coefficient associated with the high-load condition, the first damper control parameters are determined. If the second comparison result indicates that the compressor speed is greater than or equal to the first speed threshold and less than or equal to the second speed threshold, the first damper control parameters are determined based on the ambient temperature, the first ambient temperature slope coefficient and the first ambient temperature intercept coefficient associated with the low-load condition, and the second ambient temperature slope coefficient and the second ambient temperature intercept coefficient associated with the high-load condition.
