[0030] The methods and embodiments provided in this application can be executed in electronic devices or similar computing devices. Taking running on an electronic device as an example, Figure 1 This is a hardware structure block diagram of the electronic device for the vehicle defrosting control method according to an embodiment of this application. For example... Figure 1 As shown, an electronic device may include one or more ( Figure 1Only one is shown in the image.

[0033] To address the aforementioned problems, this embodiment provides a vehicle defrosting control method, applied to an electronic device, specifically a controller for the target vehicle; see reference. Figure 2 The diagram shows a flowchart of a vehicle defrosting control method, which includes the following steps S202-S208:

[0034] Step S202: In response to the defrost control command, acquire the opening influence data of the target vehicle; wherein, the opening influence data refers to the data that affects the opening of the defrost damper of the target vehicle.

[0035] It should be noted that the defrost control command refers to the logic signal received by the controller that instructs the target vehicle to enter defrost or defog mode. The defrost control command can be triggered manually by the user or automatically by the vehicle. For example, the controller may trigger the defrost control command if it determines that defrosting is necessary based on data collected from the vehicle's humidity sensor, vehicle interior temperature sensor, and exterior temperature sensor. The opening influence data refers to the set of real-time data collected from various vehicle sensors, user input interfaces, and system status modules after receiving the defrost control command, used to determine the target opening degree of the defrost damper of the target vehicle.

[0036] Step S204: Determine the initial damper opening of the defrost damper based on the opening influence data, and match the opening influence data with the set scenario conditions to determine the defrost scenario of the target vehicle.

[0037] Understandably, after acquiring the opening influence data, the initial damper opening of the defrost damper can be determined based on this data. The initial damper opening refers to the theoretically achievable basic opening percentage of the defrost damper to meet minimum defrosting requirements. Scenario conditions are a predefined set of thresholds, intervals, or enumerations that can be used to measure real-time opening influence data, thereby mapping this data to identifiable operating scenarios. A defrost scenario is a standardized operating condition label formed through multi-dimensional parameter mapping based on the vehicle's current real-time operating status and user configuration. A defrost scenario is a set of states composed of five dimensions: temperature range, fogging level, airflow direction, control source, and sensitivity preference.

[0038] For example, the heating efficiency of the target vehicle's heat pump air conditioning system varies significantly with temperature (such as ambient temperature). In low-temperature environments, the heat pump's heating capacity decreases, requiring a larger airflow to compensate for the insufficient heat carried by the air per unit volume; while in high-temperature environments, the heat pump is highly efficient, and a smaller airflow is sufficient for defrosting. Therefore, the initial damper opening can be determined based on the real-time temperature (such as real-time ambient temperature) included in the opening influence data to ensure that the initial damper opening matches the actual output capacity of the heat pump.

[0039] Step S206: Correct the initial damper opening based on the correction coefficient corresponding to the defrosting scenario to obtain the target damper opening;

[0040] Specifically, after determining the initial damper opening and the defrosting scenario, a weighted coupling algorithm can be executed to calculate the final target damper opening. That is, the initial damper opening is corrected by the correction coefficient corresponding to the defrosting scenario to obtain the target damper opening.

[0041] Step S208: Control the defrost damper according to the target damper opening to defrost the target vehicle.

[0042] Steps S202-S208 above involve acquiring the opening influence data of the target vehicle, determining the initial damper opening based on this data, and further matching the opening influence data with scenario conditions to determine the defrosting scenario. The initial damper opening is then corrected using a correction coefficient corresponding to the defrosting scenario, allowing the damper opening to be adjusted according to the defrosting scenario to obtain the target damper opening. Finally, the defrosting damper is controlled based on this target opening. This control method avoids the problem of directly looking up ambient temperature data in related solutions, which fails to adapt to the actual defrosting scenario of the vehicle, resulting in poor defrosting performance.

[0043] In some exemplary embodiments, the opening influence data includes: real-time temperature; determining the initial damper opening of the defrost damper based on the opening influence data includes: matching the real-time temperature with a plurality of preset first temperature ranges to determine the target temperature range to which the real-time temperature belongs; the target temperature range includes: a first temperature point and a second temperature point; a first temperature point being less than a second temperature point; determining a first basic opening corresponding to the first temperature point and a second basic opening corresponding to the second temperature point; inputting the real-time temperature, the first basic opening, the second basic opening, the first temperature, and the second temperature into a pre-constructed damper opening expression to determine the initial damper opening of the defrost damper; wherein, the damper opening expression is a pre-constructed expression with temperature and basic opening as independent variables and the initial damper opening as a dependent variable.

[0044] Specifically, the real-time temperature can be compared with multiple pre-stored first temperature ranges to locate the target temperature range to which the real-time temperature belongs. The target temperature range can include: a first temperature point and a second temperature point. Further, according to a pre-stored calibration mapping table, the first basic opening corresponding to the first temperature point and the second basic opening corresponding to the second temperature point are retrieved respectively. The first basic opening and the second basic opening represent the physical basic air volume required to account for the reduction in heat pump heating efficiency at a specific temperature. The real-time temperature, the first basic opening, the second basic opening, the first temperature, and the second temperature are input into a pre-constructed damper opening expression. The damper opening expression can be a linear interpolation expression, which uses temperature and basic opening as independent variables to calculate the initial damper opening.

[0045] For example, the expression for the damper opening is as follows: Pbase =P1+(T amb -T1) (P2-P1) / (T2-T1). Where, P base P1 refers to the initial damper opening; P2 refers to the first basic opening; T refers to the second basic opening; T refers to the initial damper opening. amb T1 refers to the real-time temperature; T2 refers to the first temperature; T2 refers to the second temperature.

[0046] In the above embodiments, by interpolating based on real-time temperature, it is possible to accurately compensate for insufficient heat output caused by low heat pump efficiency at low temperatures, or to avoid excessive airflow at high temperatures. This ensures that the basic airflow matches the actual output capacity of the heat pump at different temperatures, fundamentally solving the problems of slow defrosting at low temperatures and high energy consumption at high temperatures.

[0047] In an exemplary embodiment, the opening influence data further includes: real-time humidity, real-time air outlet mode, real-time control mode, and real-time sensitivity level; matching the opening influence data with set scene conditions to determine the defrosting scene of the target vehicle includes: matching real-time temperature with temperature conditions to determine a temperature scene, matching real-time humidity with fogging risk conditions to determine a fogging scene, matching real-time air outlet mode with air outlet mode conditions to determine an air outlet scene, matching real-time control mode with control mode conditions to determine a control mode scene, and matching real-time sensitivity level with sensitivity level conditions to determine a sensitivity level scene; fusing the temperature scene, fogging scene, air outlet scene, control mode scene, and sensitivity level scene to determine the fused scene as the defrosting scene of the target vehicle.

[0048] Specifically, when determining the defrosting scenario, multi-dimensional independent matching can be performed, such as temperature scenario matching, fogging scenario matching, airflow scenario matching, control mode scenario matching, and sensitivity scenario matching. For temperature scenario matching, the real-time temperature can be compared with preset temperature threshold ranges (such as -40~-20℃ in extreme cold zones, -20~0℃ in low temperature zones, etc.) to determine the current temperature scenario (such as extreme cold conditions). For fogging scenario matching, the real-time humidity and calculated dew point temperature difference can be compared with preset fogging risk level conditions to determine the current fogging scenario (such as severe fogging). For airflow scenario matching, the user-selected airflow direction (blowing towards the face / blowing towards the feet / blowing towards both the face and feet) can be identified to determine the airflow scenario. For control mode scenario matching, the source of the defrosting command (manual button / automatic algorithm) can be identified to determine the control mode scenario. For sensitivity scenario matching, the user settings (low / medium / high) can be read to determine the sensitivity level scenario.

[0049] Furthermore, the five independent scenarios mentioned above can be combined to generate a unique target vehicle defrosting scenario vector. For example, if the matching results are "extreme cold temperature", "fogging level L3", "blowing mode", "manual control", and "high sensitivity", then the final defrosting scenario determined by fusion is: extreme cold, fogging level L3, blowing mode, manual, and high sensitivity. The fused defrosting scenario serves as an index key, used to accurately look up the corresponding correction coefficient from a pre-stored calibration table, and then calculate the final target damper opening.

[0050] In the above embodiments, this multi-dimensional scene matching enables defrosting control to no longer rely solely on a single temperature or a simple fog / no-fog judgment. Through five-dimensional fusion, various operating conditions are abstracted into standardized scene labels, laying the foundation for achieving efficient defrosting control in the future.

[0051] In an exemplary embodiment, the defrosting scenario includes: a temperature scenario, a fogging scenario, an air outlet scenario, a control mode scenario, and a sensitivity level scenario. The initial damper opening is corrected based on the correction coefficient corresponding to the defrosting scenario to obtain the target damper opening, including: determining the temperature correction coefficient corresponding to the temperature scenario, determining the fogging correction coefficient corresponding to the fogging scenario, determining the air outlet correction coefficient corresponding to the air outlet scenario, determining the mode correction coefficient corresponding to the control mode scenario, and determining the level correction coefficient corresponding to the sensitivity level scenario. The product of the temperature correction coefficient, fogging correction coefficient, air outlet correction coefficient, mode correction coefficient, level correction coefficient, and the initial damper opening is determined as the target damper opening.

[0052] Specifically, based on the initial damper opening, five independent correction coefficients (corresponding to temperature, fogging, airflow, control mode, and sensitivity) can be introduced, and the final target damper opening can be calculated using a multiplicative coupling method. This multiplicative coupling allows for synergistic amplification or suppression effects among the various influencing factors. For example, under conditions of extreme cold (high coefficient) + severe fogging (high coefficient), the opening will amplify exponentially, ensuring rapid response; while under conditions of high temperature + no fog, the opening quickly returns to zero, achieving extreme energy savings.

[0053] For example, the target damper opening can be calculated based on the following formula:

[0054] P cor =P base W amb K fog K mode K air K sen ;

[0055] Among them, P cor The target damper opening; P base Refers to the initial damper opening; W amb Temperature correction factor; K fog K refers to the fogging correction factor. mode Model correction coefficient; K air Indicates the wind correction factor; K sen This refers to the gear shift correction factor.

[0056] For example, under conditions of -25°C, severe fogging, manual mode, face-blowing airflow, and sensitivity not being activated, the current operating scenario is determined to be an extremely cold manual defrosting condition. Accordingly, P base =47.5%, W amb =1.25, K fog =1.2, K mode =1.1, K air =1.1, K sen =1.0. Calculate: P cor =47.5%×1.25×1.2×1.1×1.1×1.0≈86.3%. Output P out =86.3%, at which point the damper can be opened wide for rapid defrosting.

[0057] For example, under conditions of 8°C, slight fogging, automatic mode, face-blowing airflow, and high sensitivity, the current operating scenario is determined to be a humid, automatic, high-sensitivity operating condition. Accordingly, P... base =30%, W amb =1.0, K fog =1.0, K mode =1.0, K air =1.1, K sen =1.1.

[0058] Calculate: P cor =30% × 1.0 × 1.0 × 1.0 × 1.1 × 1.1 = 36.3%. Output P out =36.3%, at this point the defogger can be turned on in advance to prevent the fog from getting worse.

[0059] For example, under the conditions of 30°C, no fog, arbitrary mode, arbitrary air outlet, and arbitrary sensitivity, the current operating scenario is determined to be a high-temperature, fog-free, energy-saving operating condition. Accordingly, K... fog =0, calculate: P cor =0. Output P out =0, at this time the damper is completely closed, and it operates with zero energy consumption.

[0060] For example, under conditions of -15°C temperature, 70% humidity inside the vehicle, automatic mode, airflow to the face, and medium sensitivity, the current operating scenario is determined to be the optimal operating condition for the adaptive algorithm. Accordingly, P... base =35%, W amb =1.05, K fog =1.15, K mode =1.0, K air =1.1, K sen =1.0. Calculate: P cor =35%×1.05×1.15×1.0×1.1×1.0≈46.4%. Output P out =46.4%, at which point continuous adaptive and precise control is possible.

[0061] In an exemplary embodiment, determining the temperature correction coefficient corresponding to a temperature scenario includes: determining a second temperature range corresponding to the temperature scenario; the second temperature range includes a third temperature point and a fourth temperature point; the third temperature of the third temperature point is lower than the fourth temperature of the fourth temperature point; determining a first temperature compensation coefficient corresponding to the third temperature point, and determining a second temperature compensation coefficient corresponding to the fourth temperature point; and determining the temperature correction coefficient based on the real-time temperature, the third temperature, the fourth temperature, the first temperature compensation coefficient, and the second temperature compensation coefficient. Specifically, the current second temperature range can be determined according to the temperature scenario. This range is defined by two calibration temperature points: the third temperature point and the fourth temperature point; according to a preset calibration mapping table, the reference compensation coefficients corresponding to these two calibration temperature points are retrieved respectively: the first temperature compensation coefficient and the second temperature compensation coefficient. Based on the real-time temperature, the third temperature, the fourth temperature, the first temperature compensation coefficient, and the second temperature compensation coefficient, linear interpolation is performed to calculate the temperature correction coefficient under the real-time temperature. Through linear interpolation, the temperature correction coefficient changes continuously and smoothly with the real-time temperature, effectively eliminating the step jump of the control signal and improving the stability of the system and the ride comfort.

[0062] In an exemplary embodiment, determining the fogging correction coefficient corresponding to a fogging scenario includes: determining the fogging level associated with the fogging scenario, and defining the fogging correction coefficient corresponding to the fogging level as the first fogging correction coefficient; determining the humidity range to which the real-time humidity belongs, and determining the second fogging correction coefficient based on the humidity range; and determining the fogging correction coefficient corresponding to the fogging scenario based on the first and second fogging correction coefficients. Thus, the fogging correction coefficient is determined through two dimensions: first, the fogging level based on preset rules (the first fogging correction coefficient), reflecting the macroscopic intensity of defogging demand; and second, the humidity range based on real-time sensor data (the second fogging correction coefficient), reflecting microscopic changes in air moisture content. The final coefficient is derived by fusing the two, ensuring both the clarity and stability of the control logic when the fogging level changes, and enabling precise compensation based on subtle differences in actual humidity at the same level, thus improving the finesse of the control.

[0063] In an exemplary embodiment, the defrosting damper is controlled according to the target damper opening to defrost the target vehicle. This includes: determining the current damper opening; determining the damper opening difference based on the current and target openings; determining the motor speed of the defrosting damper motor based on the damper opening difference; and driving the motor according to the motor speed to defrost the target vehicle. By dynamically adjusting the motor speed based on the damper opening difference, the motor operates rapidly when the damper is far from the target position and slowly when it approaches the target position, achieving a smooth motion curve of fast approach and slow arrival, significantly reducing noise and vibration during damper operation.

[0064] Obviously, the embodiments described above are only some embodiments of this application, and not all embodiments. To better understand the above method and the above vehicle defrosting control scheme, in an optional embodiment, a scheme is also provided for explaining and illustrating the above scheme.

[0065] To address the problem of poor defrosting performance in existing technologies, this application provides a vehicle defrosting control method, such as... Figure 3 The flowchart shown is for the vehicle defrosting control method provided in this application:

[0066] When defrosting control is deemed necessary, real-time data acquisition can be initiated to obtain data on the impact of the damper opening. This data includes, but is not limited to, real-time temperature, real-time humidity, real-time airflow mode, real-time control mode, and real-time sensitivity setting. The target damper opening is then calculated based on this data. When calculating the target damper opening, a base damper opening (initial damper opening) is determined based on the real-time temperature. Correction coefficients are then determined based on the real-time temperature, humidity, airflow mode, control mode, and sensitivity setting. These correction coefficients include temperature correction coefficient, fogging correction coefficient, airflow correction coefficient, mode correction coefficient, and sensitivity setting correction coefficient. The target damper opening is then determined by multiplying these coefficients by the initial damper opening. After determining the target damper opening, an opening limit process can be applied to ensure the target damper opening is between 0% and 100%. Finally, the opening limit is used to control the defrost damper motor, and real-time damper position signals are acquired during the control process. The motor speed is adjusted according to the damper position signals, with reference to... Figure 4 The diagram shows the fitting relationship between the motor control signal and the damper opening. The vertical axis represents the motor control signal, and the horizontal axis represents the damper opening. By adjusting the motor output, the damper opening can be precisely controlled. In this embodiment, the defrost damper is independent of the main mode damper, which can achieve complete decoupling between the defrost damper and the main mode damper. Under defrosting conditions, it does not interfere with the original air outlet mode and heating function in the vehicle, thus improving driving comfort.
