Description

Technical Field

[0001] This application relates to the field of vehicles, and more specifically, to a vehicle air conditioning control method, apparatus, and vehicle in the field of vehicles. Background Technology

[0002] With the increasing popularity of new energy vehicles, the level of vehicle intelligence is also increasing. Users can remotely turn on the air conditioning function through terminal devices and control the vehicle's air conditioning to heat the cabin according to the user-set preset temperature. However, when the vehicle is parked for a long time, the air inside the car does not circulate; if the vehicle's air conditioning is turned on remotely, it may result in poor air quality inside the car, affecting the comfort of the vehicle.

[0003] Therefore, when remotely turning on the vehicle's air conditioning, how to increase the amount of fresh air inside the vehicle without affecting the air conditioning function, in order to improve the vehicle's comfort, is a technical problem that needs to be solved. Summary of the Invention

[0004] This application provides a vehicle air conditioning control method, device, and vehicle. The method determines whether the vehicle has a ventilation requirement based on the vehicle's target demand level and the vehicle's parking duration. When the vehicle has a ventilation requirement, the method ventilates the vehicle according to the ventilation duration. This ensures that the content of fresh air inside the vehicle is increased without affecting the function of the vehicle's air conditioning.

[0005] Firstly, a vehicle air conditioning control method is provided, the method comprising:

[0006] In response to a remote control command for the vehicle's air conditioning, the system obtains the vehicle's target demand level and parking duration; the target demand level includes either the vehicle's heating demand level or cooling demand level.

[0007] Based on the target demand level and the vehicle's parking duration, determine whether the vehicle has a ventilation requirement;

[0008] If the vehicle requires ventilation, determine the duration of ventilation.

[0009] Based on the ventilation duration, control the ventilation of the vehicle.

[0010] In the embodiments of this application, the target demand level of the vehicle and the parking duration are obtained. Based on the target demand level and parking duration, it is determined whether the vehicle has a ventilation requirement. When it is determined that the vehicle has a ventilation requirement, the vehicle is controlled to ventilate based on the ventilation duration. Since the target demand level is used to represent the demand level for the heating or cooling function of the vehicle's air conditioning, and the parking duration may affect the content of fresh air inside the vehicle, the vehicle's ventilation requirement will differ when the target demand level and the parking duration are different. This application determines whether the vehicle has a ventilation requirement based on the target demand level and the parking duration, ensuring that the vehicle's ventilation requirement can be accurately judged and determined without affecting the heating or cooling function of the vehicle's air conditioning. Furthermore, the vehicle is controlled to ventilate based on the ventilation duration; this avoids excessively long ventilation durations that would waste energy and affect the vehicle's heating or cooling function, and avoids excessively short ventilation durations that would result in insufficient fresh air being introduced into the vehicle; thereby ensuring that the content of fresh air inside the vehicle can be increased without affecting the function of the vehicle's air conditioning, thus improving the vehicle's comfort.

[0011] In conjunction with the first aspect, some implementations of the first aspect also include:

[0012] Determine the vehicle's preset demand level;

[0013] Based on the target demand level and the vehicle's parking time, determine whether the vehicle requires ventilation, including:

[0014] If the target demand level is lower than the preset demand level, and / or the vehicle's parking time is longer than the preset time, it is determined that the vehicle has a ventilation requirement.

[0015] In the embodiments of this application, if the target demand level is lower than the preset demand level, and / or the vehicle's parking time is longer than the preset time, it is determined that the vehicle has a ventilation demand. Since a target demand level lower than the preset demand level indicates a lower target demand level for the vehicle, meaning the vehicle's air conditioning consumes less energy and has a higher rate of heating or cooling, ventilating the vehicle at this time will not affect the heating or cooling function of the vehicle's air conditioning; therefore, it is determined that the vehicle has a ventilation demand. When the vehicle's parking time is longer than the preset time, it indicates a longer parking time and poorer air quality inside the vehicle; therefore, it is determined that the vehicle has a ventilation demand, ensuring that the determination of whether a vehicle has a ventilation demand can be accurately made based on the target demand level and parking time.

[0016] In conjunction with the first aspect and the above implementation methods, in some implementation methods of the first aspect, in response to a remote control command on the air conditioning in the vehicle, the target demand level of the vehicle is obtained, including:

[0017] In response to remote control commands, the system acquires the vehicle's target temperature data, which includes the vehicle's outside temperature, inside temperature, and preset temperature.

[0018] Based on the target temperature data, the target demand level of the vehicle is determined.

[0019] In the embodiments of this application, in response to a remote control command, the target temperature data of the vehicle is acquired, and the target demand level of the vehicle is determined based on the target temperature data. Since the outside temperature, the inside temperature, and the preset temperature all affect the energy consumption of heating or cooling when the vehicle is heated or cooled, the target demand level of the vehicle is determined based on the target temperature data to ensure that the target demand level of the vehicle can be accurately measured based on the target temperature data.

[0020] In conjunction with the first aspect and the above implementation methods, some implementation methods of the first aspect also include:

[0021] Determine the target vehicle model;

[0022] If the vehicle requires ventilation, determine the duration of ventilation, including:

[0023] If the vehicle requires ventilation, determine the vehicle's air volume based on the target vehicle model;

[0024] The ventilation duration of the vehicle is determined based on the air volume and the vehicle's ventilation flow rate.

[0025] In the embodiments of this application, if the vehicle has ventilation requirements, the air volume of the vehicle is determined based on the target vehicle model; and the ventilation duration of the vehicle is determined based on the air volume and the ventilation flow rate. Since the air volume varies for different vehicle models, the air volume of the vehicle is determined according to the target vehicle model to determine the total ventilation volume of the vehicle; ensuring that the ventilation duration can be determined based on the total ventilation volume and ventilation flow rate represented by the air volume.

[0026] Combining the first aspect and the aforementioned implementation methods, in some implementation methods of the first aspect, the ventilation duration of the vehicle is determined based on the air volume and the vehicle's ventilation flow rate, including...

[0027] Determine the first ratio of the vehicle's air volume to its ventilation flow rate;

[0028] The target increment is determined based on the vehicle's outside temperature and inside temperature; the target increment is negatively correlated with the first difference between the outside temperature and the inside temperature.

[0029] The ventilation duration is determined based on the first ratio and the target increment.

[0030] In the embodiments of this application, a first ratio of air volume to ventilation flow rate is determined, and a target increment is determined; based on the first ratio and the target increment, the ventilation duration is determined. Since the outside temperature and inside temperature of the vehicle can affect the heating or cooling function of the vehicle's air conditioning, the target increment is determined based on the outside temperature and inside temperature, and the ventilation duration is determined based on the first ratio and the target increment, thereby ensuring that the ventilation duration does not affect the heating or cooling function of the vehicle's air conditioning.

[0031] Combining the first aspect and the above implementation methods, in some implementation methods of the first aspect, if the vehicle has a ventilation requirement, the ventilation duration for ventilating the vehicle is determined, including:

[0032] If a vehicle has a ventilation requirement, and the target requirement level is higher than the preset requirement level, the ventilation duration of the vehicle is determined based on the target requirement level; wherein, the ventilation duration is negatively correlated with the target requirement level.

[0033] In the embodiments of this application, if the vehicle has a ventilation requirement and the target requirement level is high, the ventilation duration is determined based on the target requirement level; the ventilation duration is negatively correlated with the target requirement level. Since the power consumption of the vehicle's heating or cooling functions is high when the target requirement level is high, and the time it takes for the vehicle to reach the preset temperature is long, the determined ventilation duration is short to ensure that the vehicle's heating or cooling functions are not affected.

[0034] Combining the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the ventilation of the vehicle is controlled based on the ventilation duration, including:

[0035] Based on the ventilation duration, the vehicle ventilation is controlled through a target control method; wherein the target control method includes at least one of the following: controlling the air conditioner to operate in a target blowing mode, the vehicle's blower to operate at maximum air volume, the vehicle's air conditioner temperature damper to be in cold air mode, the vehicle's air conditioner compressor to be in a closed state, and the vehicle to be in external circulation mode.

[0036] In conjunction with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the vehicle is equipped with a heat pump air conditioner, and after controlling the ventilation of the vehicle based on the ventilation duration, it also includes:

[0037] If the target demand level indicates that the vehicle has a heating demand, determine whether the vehicle meets the preset conditions; wherein, the preset conditions include a preset cabin temperature greater than a first threshold, or the vehicle's heating mode is the target heating mode.

[0038] If the vehicle meets the preset conditions, the vehicle's cabin will be heated through the vehicle's heat pump air conditioning and the vehicle's thermistor.

[0039] If the vehicle does not meet the preset conditions, the vehicle's cabin will be heated by the vehicle's heat pump air conditioning.

[0040] In the embodiments of this application, if the target demand level indicates that the vehicle has a heating demand, it is determined whether the vehicle meets the preset conditions. If the vehicle meets the preset conditions, it means that the vehicle's current heating load is large, and the heat pump function and the vehicle's thermistor are used to heat the vehicle cabin to ensure that the vehicle cabin can be heated quickly. If the preset conditions are not met, the heat pump air conditioner is used to heat the vehicle cabin to avoid excessive energy consumption of the vehicle's air conditioning.

[0041] Secondly, a vehicle air conditioning control device is provided, the device comprising:

[0042] The acquisition module is used to acquire the vehicle's target demand level and parking duration in response to remote control commands to the vehicle's air conditioning; wherein, the target demand level includes the vehicle's heating demand level or cooling demand level.

[0043] The first determination module is used to determine whether a vehicle has a ventilation requirement based on the target demand level and the vehicle's parking duration.

[0044] The second determining module is used to determine the ventilation duration for the vehicle if the vehicle has a ventilation requirement.

[0045] The control module is used to control the ventilation of the vehicle based on the ventilation duration.

[0046] In conjunction with the second aspect, in some implementations of the second aspect, the first determining module is specifically used to: determine the vehicle's preset demand level; if the target demand level is lower than the preset demand level, and / or the vehicle's parking time is longer than the preset time, determine that the vehicle has a ventilation requirement.

[0047] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the acquisition module is further used to: acquire the target temperature data of the vehicle in response to a remote control command; wherein the target temperature data includes the vehicle's outside temperature, inside temperature and preset temperature; and determine the vehicle's target demand level based on the target temperature data.

[0048] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the second determining module is specifically used for: determining the target vehicle model; determining the air volume of the vehicle based on the target vehicle model; and determining the ventilation duration of the vehicle based on the air volume and the ventilation flow rate of the vehicle.

[0049] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the second determining module is specifically used to: determine a first ratio of the vehicle's air volume to its ventilation flow rate; determine a target increment based on the vehicle's outside temperature and inside temperature; wherein the target increment is negatively correlated with a first difference between the outside temperature and the inside temperature; and determine the ventilation duration based on the first ratio and the target increment.

[0050] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the second determining module is specifically used to: if the vehicle has a ventilation requirement and the target requirement level is greater than the preset requirement level, determine the ventilation duration of the vehicle based on the target requirement level; wherein the ventilation duration is negatively correlated with the target requirement level.

[0051] In conjunction with the second aspect and the above implementation methods, in some implementation methods of the second aspect, the control module is specifically used to: control the vehicle to ventilate based on the ventilation duration through a target control method; wherein, the target control method includes at least one of the following: controlling the air conditioner to operate in a target blowing mode, the vehicle's blower to operate at maximum air volume, the vehicle's air conditioner temperature damper to be in cold air mode, the vehicle's air conditioner compressor to be in a closed state, and the vehicle to be in external circulation mode.

[0052] In combination with the second aspect and the above implementation methods, some implementation methods of the second aspect also include a heating module and a third determining module. The third determining module is used to: if the target demand level indicates that the vehicle has a heating demand, determine whether the vehicle meets the preset conditions; wherein, the preset conditions include a preset cabin temperature greater than a first threshold, or the vehicle's heating mode is the target heating mode.

[0053] The heating module is used to: heat the vehicle cabin through the vehicle's heat pump air conditioner and the vehicle's thermistor if the vehicle meets the preset conditions; and heat the vehicle cabin through the vehicle's heat pump air conditioner if the vehicle does not meet the preset conditions.

[0054] Thirdly, a vehicle is provided, including a memory and a processor, the memory for storing executable program code, and the processor for calling and running the executable program code from the memory, causing the vehicle to perform the methods of the first aspect or any possible implementation thereof.

[0063] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0064] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0065] With the increasing popularity of new energy vehicles, the level of vehicle intelligence is also increasing. Users can remotely turn on the air conditioning function through terminal devices and control the vehicle's air conditioning to heat the cabin according to the user's preset temperature. For example, users can remotely turn on the air conditioning function through a mobile app and set the temperature to their desired temperature before getting into the car, improving the convenience of vehicle use.

[0066] When a vehicle is parked for an extended period, the air inside becomes stagnant. Remotely turning on the air conditioning can result in poor air quality, impacting vehicle comfort. Therefore, a key technical challenge is how to increase the amount of fresh air inside the vehicle without affecting its heating and cooling functions, thereby improving comfort when remotely activating the air conditioning.

[0067] In view of this, this application provides a vehicle air conditioning control method, device, and vehicle. Through the embodiments of this application, based on the target demand level of the vehicle and the parking time of the vehicle, it is determined whether the vehicle has a ventilation demand; when the vehicle has a ventilation demand, the vehicle is ventilated according to the ventilation duration; ensuring that the content of fresh air in the vehicle is increased without affecting the function of the vehicle air conditioning, thereby improving the comfort of the vehicle.

[0068] Figure 1 This is a schematic diagram of a scenario provided in an embodiment of this application.

[0069] For example, scenario 100 includes a vehicle 110 and a terminal device 120, which can be a mobile phone. The user sends a remote control command to the vehicle through the terminal device 120, which can be used to control the vehicle's air conditioning. When the vehicle 110 receives the remote control command sent by the terminal device, it responds to the command by turning on the vehicle's air conditioning and heating or cooling the vehicle's cabin.

[0070] Figure 2 This is a schematic flowchart of a vehicle air conditioning control method provided in an embodiment of this application.

[0071] For example, Figure 2 The method 200 shown can be performed by a vehicle, or by a processor or chip in the vehicle.

[0072] like Figure 2 As shown, the vehicle air conditioning control method 200 includes S210 to S240, and S210 to S240 are described in detail below.

[0073] S210, in response to a remote control command for the vehicle's air conditioning, obtains the vehicle's target demand level and the vehicle's parking duration.

[0074] Remote control commands are commands triggered by the user on a terminal device to control the vehicle's air conditioning. Terminal devices include, but are not limited to, mobile phones, tablets, smart keys, and smartwatches. The target demand level indicates the level of demand for the vehicle's heating or cooling functions; the target demand level includes the vehicle's heating or cooling demand level.

[0075] For example, the vehicle's parking time is calculated from the time the vehicle is powered off until the time it is powered on again. The time difference between the two counts is the vehicle's parking time. For instance, if the vehicle is powered off at 12:00 on November 1st and powered on again at 13:00 on November 2nd, then the vehicle's parking time is determined to be 25 hours.

[0076] The following explains the target requirement level for acquiring vehicles.

[0077] In one implementation, in response to a remote control command for the vehicle's air conditioning, the target demand level of the vehicle is obtained, including:

[0078] In response to remote control commands, the system acquires the vehicle's target temperature data, which includes the vehicle's outside temperature, inside temperature, and preset temperature. Based on the target temperature data, the system determines the vehicle's target demand level.

[0079] The preset temperature setting allows users to set a target temperature for the vehicle's cabin.

[0080] For example, target temperature data of the vehicle is acquired, and the target demand level of the vehicle is determined based on the target temperature data. Since a larger temperature difference between the outside and inside of the vehicle, or a larger temperature difference between the outside and a preset temperature, results in greater power consumption for the vehicle to reach the preset temperature, the target demand level for heating or cooling is higher. Specifically, determining the target demand level based on the target temperature data can be understood as determining the target demand level based on a first difference between the outside and inside temperatures and a second difference between the outside and the preset temperature.

[0081] Specifically, determine the first difference between the outside temperature and the inside temperature, and determine the second difference between the preset temperature and the outside temperature; based on the first difference and the second difference, determine the target demand level; that is, the first difference = outside temperature - inside temperature; the second difference = preset temperature - outside temperature.

[0082] For example, the correspondence between the first and second differences and the heating demand level can be shown in Table 1:

[0083] Table 1

[0084]

[0085] For example, when the first difference is greater than -5℃ and less than or equal to 0℃, and the second difference is greater than 0℃ and less than or equal to 5℃, the target demand level is determined to be Level 1 heating; when the first difference is greater than -10℃ and less than or equal to -5℃, and the second difference is greater than 5℃ and less than or equal to 10℃, the target demand level is determined to be Level 2 heating; when the first difference is less than or equal to -10℃ and the second difference is greater than 10℃, the target demand level is determined to be Level 3 heating.

[0086] For example, the correspondence between the first difference, the second difference, and the cooling demand level can be shown in Table 2:

[0087] Table 2

[0088]

[0089] For example, when the first difference is greater than 0°C and less than or equal to 5°C, and the second difference is greater than -5°C and less than or equal to 0°C, the target demand level is determined to be Level 1 cooling. When the first difference is greater than 5°C and less than or equal to 10°C, and the second difference is greater than -10°C and less than or equal to -5°C, the target demand level is determined to be Level 2 cooling. When the first difference is greater than 10°C and the second difference is less than or equal to -10°C, the target demand level is determined to be Level 3 cooling.

[0090] It should be noted that Tables 1 and 2 above are illustrative examples of the correspondence between target temperature data and target demand levels, and this application does not impose any limitations on them.

[0091] Optionally, when determining whether the target demand level is a heating demand level or a cooling demand level, it can be determined based on remote control commands; for example, if the user clicks "Heating" on the terminal device, the heating demand level is determined based on the target temperature data; if the user clicks "Cooling" on the terminal device, the cooling demand level is determined based on the target temperature data.

[0092] Optionally, heating or cooling demand can be determined based on target temperature data. When both the outside and inside temperatures are lower than the preset temperature, it indicates a heating demand; in this case, the heating demand level is determined based on the target temperature data. When both the outside and inside temperatures are higher than the preset temperature, it indicates a cooling demand; in this case, the cooling demand level is determined based on the target temperature data.

[0093] In the embodiments of this application, in response to a remote control command, the target temperature data of the vehicle is acquired, and the target demand level of the vehicle is determined based on the target temperature data. Since the outside temperature, the inside temperature, and the preset temperature all affect the energy consumption of heating or cooling when the vehicle is heated or cooled, the target demand level of the vehicle is determined based on the target temperature data to ensure that the target demand level of the vehicle can be accurately measured based on the target temperature data.

[0094] S220 determines whether a vehicle requires ventilation based on the target demand level and the vehicle's parking duration.

[0095] In one implementation, a preset demand level for the vehicle is determined; if the target demand level is lower than the preset demand level, and / or the vehicle's parking time is longer than the preset time, it is determined that the vehicle has a ventilation requirement.

[0096] For example, when the target demand level is lower than the preset demand level, it indicates that the vehicle's target demand level is relatively low; the vehicle's air conditioning consumes less energy when heating or cooling, and the heating or cooling rate is relatively high. Therefore, ventilating the vehicle in this situation will not affect the heating or cooling function of the vehicle's air conditioning; thus, it is determined that the vehicle has a ventilation need. When the vehicle's parking time exceeds the preset time, it indicates that the parking time is relatively long, and the air quality inside the vehicle is relatively poor; therefore, it is determined that the vehicle has a ventilation need. This ensures that the determination of whether a vehicle has a ventilation need can be accurately made based on the target demand level and parking time.

[0097] For example, taking air conditioning heating as an example, if the preset demand level is level 2 heating and the preset duration is 8 hours (h), the target demand level of the vehicle is found to be level 1 heating, and the vehicle's parking time is 10 hours; since the target demand level is lower than the preset demand level and the parking time is longer than the preset duration, it is determined that the vehicle has a ventilation requirement.

[0098] It should be noted that the above are examples illustrating the preset duration and the level of air conditioning heating demand; this application does not limit this.

[0099] S230, if the vehicle requires ventilation, determine the duration of ventilation.

[0100] It should be noted that excessive ventilation time may lead to wasted power consumption and may affect the vehicle's heating or cooling functions; conversely, insufficient ventilation time may result in inadequate fresh air intake, failing to effectively increase the fresh air content inside the vehicle. Therefore, it is necessary to determine a suitable ventilation time and ventilate the vehicle accordingly. The method for determining the ventilation time is explained below.

[0101] In one implementation, when a vehicle has a ventilation requirement, the target vehicle model is determined; based on the target vehicle model, the vehicle's air volume is determined; and based on the air volume and the vehicle's ventilation flow rate, the vehicle's ventilation duration is determined.

[0102] For example, based on the target vehicle model, the vehicle's air volume is determined; and based on the air volume and the vehicle's ventilation flow rate, the vehicle's ventilation duration is determined. Since different vehicle models correspond to different air volumes, the vehicle's air volume is determined according to the target vehicle model to determine the vehicle's total ventilation volume; ensuring that the ventilation duration can be determined based on the total ventilation volume and ventilation flow rate represented by the air volume.

[0103] In one implementation, the ventilation duration of the vehicle is determined based on the air volume and the vehicle's ventilation flow rate, including...

[0104] Determine the first ratio of the vehicle's air volume to its ventilation flow rate; determine the target increment based on the vehicle's outside temperature and inside temperature; wherein the target increment is negatively correlated with the first difference between the outside temperature and the inside temperature; determine the ventilation duration based on the first ratio and the target increment.

[0105] For example, a first ratio of the vehicle's air volume to its ventilation flow rate is determined, such as determining the vehicle's air volume as M (cubic meters) based on the target vehicle model; and the ventilation flow rate of the vehicle's air conditioning system during ventilation as N cubic meters per second (m³ / s). 3 If the air volume is M / s, then the first ratio of air volume to ventilation flow rate is determined to be M / S (seconds).

[0106] For example, when determining the target increment, a first difference between the outside temperature and the inside temperature is determined, and the target increment corresponding to the first difference and the outside temperature is determined based on the mapping relationship between the first difference and the outside temperature and the increment.

[0107] Optionally, if the target demand level is the heating demand level, the target increment is positively correlated with the outside temperature and negatively correlated with the first difference between the outside temperature and the inside temperature; if the target demand level is the cooling demand level, the target increment is negatively correlated with the outside temperature and negatively correlated with the first difference between the outside temperature and the inside temperature.

[0108] It should be noted that when the target demand level is either heating or cooling, a larger first difference indicates a greater load when heating or cooling the vehicle. Therefore, to reduce energy consumption during vehicle heating, a larger first difference corresponds to a smaller target increment. Conversely, when the outside temperature is higher, if the target demand level is heating, the outside temperature is closer to the vehicle cabin temperature, resulting in a smaller load. Therefore, a longer ventilation duration is determined (i.e., a larger target increment for higher outside temperatures) to ensure sufficient ventilation of the vehicle cabin. Conversely, when the target demand level is cooling, a higher outside temperature results in greater power consumption during cooling. To reduce cooling power consumption, a shorter ventilation duration is required (i.e., a smaller target increment for higher outside temperatures) to avoid excessive power consumption during ventilation and its impact on the vehicle's cooling function.

[0109] For example, let's take heating demand as an example. The increment is t. offset The outside temperature is T. amb With the temperature inside the car T incar The first difference is T err Outside temperature T amb The larger t is, the greater offset The larger the value; the greater the first difference T err The larger t is, the greater offset The smaller the value, the better. The mapping relationship between the first difference and the outside temperature and increment can be shown in Table 3. Different outside temperatures correspond to different increments with different first differences.

[0110] Table 3

[0111]

[0112] It should be noted that the above is an example illustrating the mapping relationship between the first difference and the outside temperature and increment, and this application does not limit it.

[0113] It should be understood that, for ease of understanding, the table above shows T based on specific temperature values. err With T amb The division can be made based on T; in practical application scenarios, it can be based on T err With T amb Divide the interval into intervals, each T err Interval and each T amb Different intervals correspond to different increments.

[0114] In one possible implementation, the ventilation duration can be determined based on the formula for calculating ventilation duration t; the formula for calculating t is:

[0115] t = K × (vehicle air volume ÷ maximum ventilation flow rate in face and foot blowing modes) + target increment.

[0116] K is 1 when the vehicle has no glass roof; K is 0.9 when the vehicle has a glass roof. The coefficient can also be adjusted according to the actual effect.

[0117] In the embodiments of this application, a first ratio of air volume to ventilation flow rate is determined, and a target increment is determined; based on the first ratio and the target increment, the ventilation duration is determined. Since the outside temperature and inside temperature of the vehicle can affect the heating or cooling function of the vehicle's air conditioning, the target increment is determined based on the outside temperature and inside temperature, and the ventilation duration is determined based on the first ratio and the target increment, thereby ensuring that the ventilation duration does not affect the heating or cooling function of the vehicle's air conditioning.

[0118] In one implementation, if the vehicle has a ventilation requirement, the duration of ventilation for the vehicle is determined, including:

[0119] If a vehicle has a ventilation requirement, and the target requirement level is higher than the preset requirement level, the ventilation duration of the vehicle is determined based on the target requirement level; wherein, the ventilation duration is negatively correlated with the target requirement level.

[0120] For example, when the target demand level is high, the demand for the vehicle's heating or cooling functions is high, the power consumption of the vehicle's heating or cooling functions is high, and the time to reach the preset temperature is long; therefore, the ventilation duration is determined based on the target demand level to ensure that the vehicle's heating or cooling functions are not affected.

[0121] For example, if the preset heating requirement level is level two, but the vehicle's target heating requirement level is level three, the time required to reach the user-set preset temperature will be longer (e.g., 6 minutes), and the power consumption will be higher. If the user gets into the vehicle after 8 minutes, excessive ventilation time may result in the vehicle's cabin temperature not reaching the preset temperature when the user enters, thus affecting the vehicle's heating function. Furthermore, because the target requirement level is high, a longer ventilation time may also impact the vehicle's heating function due to the increased power consumption. Therefore, to prioritize ensuring the vehicle's heating function is not affected, the ventilation time is determined based on the target requirement level.

[0122] It should be noted that the above are examples illustrating the preset demand levels and durations; this application does not impose any limitations on them.

[0123] S240 controls vehicle ventilation based on ventilation duration.

[0124] For example, vehicle ventilation is controlled based on ventilation duration, that is, the vehicle is ventilated and ventilation is stopped when the ventilation duration is reached.

[0125] In one implementation, the vehicle is ventilated by a target control method based on the ventilation duration; wherein the target control method includes at least one of the following: controlling the air conditioner to operate in a target blowing mode, the vehicle's blower to operate at maximum air volume, the vehicle's air conditioner temperature damper to be in a cold air state, the vehicle's air conditioner compressor to be in a closed state, and the vehicle to be in an external circulation mode.

[0126] For example, each of the target control methods is described.

[0127] Method 1: Control the air conditioner to operate in the target airflow mode. The target airflow mode is the operating mode with a higher airflow rate. For example, the target airflow mode could be the face / foot blowing mode. Vehicle air conditioner airflow modes include face blowing mode, foot blowing mode, and face / foot blowing mode. Since the airflow rate is higher in face / foot blowing mode, controlling the air conditioner to operate in face / foot blowing mode ensures that the vehicle is ventilated with a larger airflow, thereby improving ventilation efficiency.

[0128] Method 2: Control the vehicle's blower to operate at maximum airflow. Since the vehicle can take in air through the blower, controlling the vehicle's blower to operate at maximum airflow ensures a large air intake when ventilating the vehicle, thereby improving the ventilation efficiency.

[0129] Method 3: Set the vehicle's air conditioning to cold air mode and turn off the air conditioning compressor. Since the vehicle's power consumption is lower when the air conditioning is in cold air mode and the compressor is off, setting the air conditioning to cold air mode ensures lower power consumption when ventilating the vehicle.

[0130] Method 4: Keep the vehicle in external air circulation mode. Since ventilating a vehicle involves expelling the air inside and drawing in outside air to increase the amount of fresh air inside, it is necessary to keep the vehicle in external air circulation mode.

[0131] In one implementation, the vehicle is equipped with a heat pump air conditioner, and after controlling the ventilation of the vehicle based on the ventilation duration, it also includes:

[0132] If the target demand level indicates that the vehicle has a heating demand, determine whether the vehicle meets the preset conditions; wherein, the preset conditions include the preset temperature being greater than the first threshold, or the vehicle's heating mode being the target heating mode.

[0133] If the vehicle meets the preset conditions, the vehicle's cabin will be heated through the vehicle's heat pump air conditioning and the vehicle's thermistor; if the vehicle does not meet the preset conditions, the vehicle's cabin will be heated through the vehicle's heat pump air conditioning.

[0134] For example, when a vehicle is equipped with a heat pump air conditioner, after ventilating the vehicle, if the vehicle has a heating demand, the heat pump air conditioner will be used to heat the vehicle first. When the vehicle meets the preset conditions, it means that the vehicle's current heating load is large, and the heat pump function and the vehicle's thermistor will be used to heat the vehicle cabin to ensure that the vehicle cabin can be heated quickly.

[0135] It's important to note that the power consumption of a vehicle using a heat pump air conditioner for heating is less than that using a thermistor (Positive Temperature Coefficient, PTC). Heat pump air conditioners absorb heat from the external environment and transfer it into the vehicle. Their Coefficient of Performance (COP) is typically between 2 and 4, meaning that for every unit of electricity consumed, the heat pump can provide 2 to 4 units of heat. In contrast, a PTC heater is a resistance heater with a COP close to 1, meaning that for every unit of electricity consumed, the PTC heater can only provide 1 unit of heat. Secondly, heat pump air conditioners have higher energy conversion efficiency than PTC air conditioners. Heat pump air conditioners absorb heat from the external environment and transfer it into the vehicle through a compressor and refrigerant circulation system, even in low temperatures. PTC heaters, on the other hand, directly convert electrical energy into heat energy through resistance heating, a method with lower energy conversion efficiency.

[0136] In the above embodiments, since the target demand level is used to represent the demand level for the heating or cooling function of the vehicle's air conditioning, and the parking duration affects the fresh air content inside the vehicle, the vehicle's ventilation demand differs when the target demand level and the parking duration are different. This application determines whether the vehicle has a ventilation demand based on the target demand level and the vehicle's parking duration, ensuring accurate judgment of the vehicle's ventilation demand and determining the vehicle's ventilation demand without affecting the heating or cooling function of the vehicle's air conditioning. Furthermore, based on the ventilation duration, the vehicle's ventilation is controlled; excessively long ventilation durations avoid energy waste and impact on the vehicle's heating or cooling function; and excessively short ventilation durations avoid insufficient fresh air being introduced into the vehicle; thereby ensuring that the fresh air content inside the vehicle is increased without affecting the function of the vehicle's air conditioning, thus improving vehicle comfort.

[0137] Figure 3 This is a schematic flowchart of a vehicle air conditioning control method provided in an embodiment of this application.

[0138] For example, Figure 3 The method 300 shown can be performed by a vehicle, or by a processor or chip in the vehicle.

[0139] like Figure 3 As shown, the vehicle air conditioning control method 300 includes S301 to S309, and S301 to S309 are described in detail below.

[0140] S301, in response to remote control commands to the vehicle's air conditioning, acquires target temperature data and parking duration.

[0141] Alternatively, the implementation of S301 can be found in [reference needed]. Figure 2 The relevant descriptions of S210 will not be repeated here.

[0142] S302 determines the target demand level of the vehicle based on the target temperature data.

[0143] The target demand level for the vehicle includes the vehicle's heating demand level and the vehicle's cooling demand level; the target temperature data includes the vehicle's interior temperature, exterior temperature (ambient temperature), and preset temperature.

[0144] For example, the target demand level (i.e. heating / cooling demand level) is determined based on the first difference between the outside temperature and the inside temperature, and the second difference between the preset temperature and the outside temperature. The larger the first difference and the larger the second difference, the higher the corresponding target demand level.

[0145] For example, the target demand level can be determined as either a heating demand level or a cooling demand level based on the target temperature data. When both the outside and inside temperatures are lower than the preset temperature, it indicates that the vehicle has a heating demand, meaning the target demand level is a heating demand level. When both the outside and inside temperatures are higher than the preset temperature, it indicates that the vehicle has a cooling demand, meaning the target demand level is a cooling demand level.

[0146] S303 If the target demand level is lower than the preset demand level, or the parking time is longer than the preset time, ventilation demand is determined to exist.

[0147] Alternatively, the implementation of S303 can be found in [reference needed]. Figure 2 The relevant descriptions of the S220 are not repeated here.

[0148] S304, determine the vehicle's air volume based on the target vehicle model.

[0149] For example, since the air volume of different vehicle models varies, the air volume of the vehicle is determined based on the target vehicle model; the air volume of the vehicle can be determined according to the vehicle's volume, the larger the vehicle's volume, the larger the air volume of the vehicle's cabin.

[0150] Optionally, the vehicle's air volume can be pre-calibrated and stored, and the vehicle's air volume can be determined by reading the stored data.

[0151] S305, determine the first ratio of the vehicle's air volume to the vehicle's ventilation flow rate.

[0152] For example, the ventilation flow rate of a vehicle is the maximum volumetric flow rate when the vehicle is ventilated, and a first ratio of air volume to ventilation flow rate is determined.

[0153] For example, if a vehicle ventilates its cabin by adjusting the air conditioning to face-and-foot-blowing mode, the ventilation flow rate is the maximum ventilation flow rate when the vehicle is in face-and-foot-blowing mode.

[0154] S306, determine the target increment based on the target temperature data.

[0155] Specifically, if the target demand level is the heating demand level, the target increment is positively correlated with the outside temperature and negatively correlated with the first difference between the outside temperature and the inside temperature; if the target demand level is the cooling demand level, the target increment is negatively correlated with the outside temperature and negatively correlated with the first difference between the outside temperature and the inside temperature.

[0156] S307, based on the first ratio and the target increment, determines the ventilation duration.

[0157] For example, a first ratio of air volume to ventilation flow rate is determined, and a target increment is determined; based on the first ratio and the target increment, the ventilation duration is determined. Since the outside temperature and the inside temperature of the vehicle can affect the heating or cooling function of the vehicle's air conditioning, the target increment is determined based on the outside temperature and the inside temperature, and the ventilation duration is determined based on the first ratio and the target increment, thereby ensuring that the ventilation duration does not affect the heating or cooling function of the vehicle's air conditioning.

[0158] S308 controls vehicle ventilation based on ventilation duration.

[0159] For example, vehicle ventilation is controlled by a target control method; wherein the target control method includes at least one of the following: controlling the air conditioner to operate in a target blowing mode, the vehicle's blower to operate at maximum air volume, the vehicle's air conditioner temperature damper being in a cold air state, and the vehicle being in an external circulation mode.

[0160] Alternatively, the implementation of S308 can be found in [reference needed]. Figure 2 The relevant description of S240 will not be repeated here.

[0161] S309, after ventilation is completed, heats or cools the vehicle cabin according to the target requirement level.

[0162] For example, if the target demand level is the heating demand level, the vehicle cabin is heated after the vehicle is ventilated; if the target demand level is the cooling demand level, the vehicle is cooled after the vehicle is ventilated.

[0163] In the embodiments of this application, the presence of ventilation needs in the vehicle is determined based on the target demand level and the parking duration. When the target demand level of the vehicle differs from the parking duration, different ventilation durations are determined to avoid energy waste caused by excessively long ventilation durations and to prevent impact on the vehicle's heating or cooling functions. Furthermore, the ventilation duration is kept short to avoid insufficient fresh air being introduced into the vehicle. This ensures that the amount of fresh air inside the vehicle can be increased without affecting the vehicle's air conditioning function, thereby improving the vehicle's comfort.

[0164] Figure 4 This is a schematic flowchart of another vehicle air conditioning control method provided in the embodiments of this application.

[0165] Figure 4 The method 400 shown can be performed by a vehicle; or it can be performed by a processor or chip in the vehicle.

[0166] like Figure 4 As shown, the vehicle air conditioning control method 400 is a flowchart of the vehicle air conditioning control method under heating conditions. The vehicle air conditioning control method 400 includes S401 to S417, and S401 to S417 are described in detail below.

[0167] S401, Begin.

[0168] For example, the starting step of S401 can be understood as starting to execute the vehicle air conditioning control method when a remote control command for the vehicle air conditioning is detected; that is, S401 is the triggering step for triggering the vehicle air conditioning control method 400.

[0169] Among them, remote control commands are control commands for the vehicle's air conditioning triggered by the user in a terminal device; terminal devices include, but are not limited to, mobile phones, tablets, smart keys, and smartwatches.

[0170] S402, Is the air conditioning system remotely activated? If yes, proceed to S403; if no, proceed to S404.

[0171] For example, determine whether the vehicle's air conditioning system is remotely activated; if so, further determine whether the vehicle has a heating requirement; if the air conditioning system is not remotely activated, maintain the current state of the air conditioning and execute the vehicle's control strategy for internal and external air circulation under the current state.

[0172] S403, Is there a heating requirement? If yes, proceed to S405; if no, proceed to S415.

[0173] For example, determine whether there is a heating demand; if there is a heating demand, execute step S405 to determine whether the vehicle meets any of the four preset conditions; if there is no heating demand, determine the priority of the vehicle's internal and external circulation requests in conjunction with other modules.

[0174] S404, Maintain the current state of the air conditioner and execute the control strategy for internal and external circulation under the current state.

[0175] For example, when the vehicle does not require heating, the air conditioning remains in its current state; for example, if the vehicle is currently in recirculation mode, the vehicle is controlled to execute the recirculation control strategy; if the air conditioning damper is currently closed, the vehicle air conditioning is controlled to keep the damper closed.

[0176] S405. Does the target condition meet any of the four target conditions? If yes, proceed to S406; otherwise, proceed to S409.

[0177] For example, it is determined whether any of the four target conditions are met; if yes, it means that the vehicle has a ventilation requirement, and the ventilation operation in S406 is executed; if no, it means that the vehicle does not have a ventilation requirement, and the heating operation of the vehicle is executed.

[0178] The four target conditions include:

[0179] Condition a: -5℃≤outside temperature -inside temperature < -1℃ and 0℃<set preset temperature -outside temperature≤5℃;

[0180] Condition b: -4℃ ≤ glass temperature - interior temperature < 0.5℃ and 0℃ < preset temperature - exterior temperature ≤ 5℃;

[0181] Condition c: The current heating demand is in the low range, that is, the current heating demand is ≤ 30% of the maximum heating demand (the maximum heating demand is the pre-calculated lookup value of the current outside temperature and the preset temperature).

[0182] Condition d: The parking time for this parking session is ≥10 hours.

[0183] For example, conditions a, b, and c of the four target conditions are used to determine the current heating demand; if the vehicle meets any one of conditions a, b, or c, it indicates that the vehicle's heating demand is low. Condition d is used to determine if the current parking time is long. If the vehicle meets any one of the four target conditions, it indicates that the current vehicle's heating demand is low, or the vehicle's parking time is long, and the ventilation operation in S406 can be performed.

[0184] For example, when the current heating demand is low or the parking time is long, to avoid discomfort caused by poor air quality inside the vehicle, fresh outside air is introduced into the passenger compartment before heating. This increases the amount of fresh air inside the vehicle, improving comfort, while also considering energy consumption and heating rate. If the heating demand is high (conditions a, b, and c are not met), only the air quality issue in the passenger compartment caused by prolonged parking is considered. When the heating load is high, priority is given to ensuring the heating rate and energy consumption; that is, when the heating demand is high, if vehicle ventilation is required, the ventilation duration needs to be adjusted according to the heating demand. The higher the heating demand, the shorter the ventilation duration; ensuring that the heating rate and energy consumption are prioritized.

[0185] S406, the air conditioner blowing mode is set to face / foot blowing mode, the temperature damper is set to full cooling position, the blower is set to maximum airflow, the internal and external circulation is set to external circulation, and the air conditioner compressor and PTC are kept off.

[0186] For example, when ventilating a vehicle, the air conditioning blowing mode is adjusted to face / foot blowing mode, the temperature damper is adjusted to the full cooling position, the blower is adjusted to the maximum air volume, the internal and external circulation is set to external circulation, and the air conditioning compressor and PTC are kept off; this ensures that the vehicle can be ventilated with a large amount of air (intake and exhaust volume), improving ventilation efficiency while reducing ventilation power consumption.

[0187] S407, determine the runtime t of the face / foot blowing mode.

[0188] For example, the formula for calculating t is: t = K × (Vehicle interior air volume ÷ Maximum airflow (volume flow rate) in face and foot blowing modes) + t offset ,

[0189] Where K is 1 when the vehicle has no glass roof and 0.9 when the vehicle has a glass roof, the coefficient can also be adjusted according to the actual effect; t offset For a temperature based on the outside temperature (ambient temperature) T amb and the temperature inside the car (T) incar With the outside temperature T amb The difference T err Values ​​from the table (see Table 3); Ambient temperature T amb The larger t is, the greater offset The larger T is err The larger t is, the greater offset The smaller.

[0190] Alternatively, the implementation of S407 can be found in [reference needed]. Figure 2 The relevant descriptions regarding the determination of ventilation duration in S230 are not repeated here.

[0191] S408, Is the air conditioner's running time greater than t? If yes, proceed to S409; otherwise, proceed to S402.

[0192] For example, if the air conditioner has been running for t days in the face / foot blowing mode, the remote air conditioning request is maintained, and the system continues to determine whether the current vehicle is configured as a heat pump air conditioning system.

[0193] If the air conditioner has not run for the required time t in the face / foot blowing mode, and the remote air conditioning request is detected as canceled, then it is necessary to return to S402 to determine whether the current air conditioning system has enabled the remote air conditioning request, and then execute the corresponding strategy.

[0194] S409, Is the air conditioning system a heat pump air conditioning system? If yes, proceed to S410; if no, proceed to S411.

[0195] For example, determine whether the vehicle's air conditioning system is a heat pump air conditioning system; if the air conditioning system is a heat pump air conditioning system, determine whether the remote air conditioning is set to rapid heating mode or whether the preset temperature is ≥30℃; if the air conditioning system is not a heat pump air conditioning system, the PTC can be turned on or off according to the heating algorithm requirements.

[0196] S410: Is the remote air conditioner set to rapid heating mode or is the preset temperature ≥30℃? If yes, proceed to S412; otherwise, proceed to S413.

[0197] For example, determine whether the remote air conditioner is set to rapid heating mode or whether the preset temperature is ≥30℃; if so, use the heat pump air conditioning system for heating, and the PTC can be turned on or off according to the heating algorithm requirements. If not, only use the heat pump air conditioning system for heating, and the PTC should be disabled.

[0198] S411 allows you to turn PTC on or off depending on the heating algorithm requirements.

[0199] For example, if the vehicle's air conditioning is not a heat pump air conditioning system, the vehicle will turn the PTC on or off according to the heating algorithm; that is, the PTC will be turned on to heat the vehicle cabin when there is a heating demand, and the PTC will be turned off when there is no heating demand.

[0200] S412 uses a heat pump air conditioning system for heating, and turns the PTC on or off according to the heating algorithm requirements.

[0201] For example, when a heat pump air conditioning system is present in the vehicle, and the remote air conditioning is set to rapid heating mode or preset temperature ≥30℃, it indicates that the vehicle's current heating load is large. Based on the heating algorithm requirements, if PTC heating is required, the vehicle uses both the heat pump air conditioning system and PTC to heat the vehicle cabin simultaneously; if PTC heating is not required, the vehicle uses the heat pump air conditioning system for heating.

[0202] S413, only use the heat pump air conditioning system for heating, PTC is prohibited from being turned on.

[0203] For example, if the remote air conditioning is not set to rapid heating mode or the preset temperature is less than 30°C, it indicates that the vehicle's current heating load is low. The heat pump air conditioning system can heat the vehicle cabin; therefore, only the heat pump air conditioning system should be used for heating, and the PTC should not be turned on. This ensures that while heating the vehicle cabin is possible, excessive power consumption is avoided.

[0204] S414, the vehicle's internal and external air circulation is set to internal circulation.

[0205] For example, after the vehicle has been heated, the vehicle's internal and external air circulation can be set to internal circulation to ensure the heating effect of the vehicle's cabin.

[0206] S415, in conjunction with other modules, determines the priority of vehicle internal and external circulation requests, and executes the internal and external circulation control strategy according to the request priority.

[0207] Other modules include, but are not limited to, safety-related modules such as defrosting and automatic defogging, comfort modules, air quality modules, and ventilation modules.

[0208] For example, the request priorities for internal and external air circulation are arbitrated in conjunction with other modules, and the arbitrated automatic internal and external air circulation control strategy is executed. Since multiple modules in the vehicle have control requirements for the vehicle's internal and external air circulation, the control strategy for internal and external air circulation needs to be determined based on the request priorities of multiple modules. The request priorities are ordered from high to low as requests involving safety have a higher priority than requests involving comfort; that is, lower priority requests will only be considered for execution if there is no safety risk.

[0209] For example, when the risk level of automatic defogging is high, fogging can impair the driver's visibility and, in severe cases, cause traffic accidents. In such situations, if the comfort module calculates a different recirculation operation than the automatic defogging module, the automatic defogging algorithm should be prioritized for controlling the internal and external recirculation. If the vehicle encounters an area with air pollution, and after detecting no risk of fogging, the air quality module should be used to switch the recirculation to internal recirculation to prevent the polluted air from affecting the air quality in the vehicle's cabin.

[0210] It should be noted that the above are illustrative examples of the determination and implementation of request priority, and this application does not limit them.

[0211] S416, other air conditioning settings are set to operate in remote automatic mode, and the temperature is set by the user.

[0212] For example, the above describes the settings for the vehicle's air conditioning system (heating via a heat pump air conditioning system or PTC) and the vehicle's internal and external air circulation. All other settings except those described above operate in remote automatic air conditioning mode (AUTO mode), which means that the vehicle can automatically adjust the temperature and wind speed of the air vents according to the temperature difference between the inside and outside of the vehicle, and automatically adjust the position and direction of the air vents to achieve the best comfort effect.

[0213] S417, End.

[0214] In the embodiments of this application, when the remote air conditioning is turned on, it is determined whether the vehicle has heating and ventilation needs. If ventilation is needed, the vehicle is ventilated first before heating. This effectively solves the problem that harmful gases released from the interior or volatile items of a vehicle that has been parked for a long time cannot be expelled from the vehicle in a timely manner under remote air conditioning mode. It also ensures that the fresh air content in the vehicle is increased when the remote air conditioning ends, thereby improving comfort. If there is no ventilation need, the vehicle is directly heated. When heating, the more efficient heat pump air conditioning system is prioritized, reducing the frequency and duration of PTC usage, and the control algorithm is more energy-efficient. This addresses the problem of the current single air conditioning heating control strategy and excessive air conditioning energy consumption under remote air conditioning mode, and improves the vehicle's driving range.

[0215] The above text combined Figures 1 to 4 The vehicle air conditioning control method provided in the embodiments of this application is described in detail below; the following will be combined with Figure 5 and Figure 6 The apparatus embodiments of this application are described in detail below. It should be understood that the apparatus in the embodiments of this application can perform the various methods described in the foregoing embodiments of this application, that is, the specific working processes of the various products described below can be referred to the corresponding processes in the foregoing method embodiments.

[0216] Figure 5 This is a schematic diagram of the structure of a vehicle air conditioning control device provided in an embodiment of this application.

[0217] For example, such as Figure 5 As shown, the vehicle air conditioning control device 500 includes:

[0218] The acquisition module 510 is used to acquire the target demand level of the vehicle and the parking duration in response to a remote control command for the air conditioning in the vehicle; wherein, the target demand level includes the heating demand level or the cooling demand level of the vehicle.

[0219] The first determining module 520 is used to determine whether the vehicle has a ventilation requirement based on the target demand level and the vehicle's parking duration.

[0220] The second determining module 530 is used to determine the ventilation duration of the vehicle if the vehicle has a ventilation requirement.

[0221] The control module 540 is used to control the ventilation of the vehicle based on the ventilation duration.

[0222] Optionally, as an embodiment, the first determining module 520 is specifically used to: determine the preset demand level of the vehicle; if the target demand level is less than the preset demand level, and / or the parking time of the vehicle is greater than the preset time, determine that the vehicle has a ventilation demand.

[0223] Optionally, as an embodiment, the acquisition module 510 is further configured to: acquire target temperature data of the vehicle in response to a remote control command; wherein the target temperature data includes the vehicle's outside temperature, inside temperature and preset temperature; and determine the vehicle's target demand level based on the target temperature data.

[0224] Optionally, as an embodiment, the second determining module 530 is specifically used for: determining the target vehicle model; determining the vehicle's air volume based on the target vehicle model; and determining the vehicle's ventilation duration based on the air volume and the vehicle's ventilation flow rate.

[0225] Optionally, as an embodiment, the second determining module 530 is specifically used to: determine a first ratio of the vehicle's air volume to its ventilation flow rate; determine a target increment based on the vehicle's outside temperature and inside temperature; wherein the target increment is negatively correlated with a first difference between the outside temperature and the inside temperature; and determine the ventilation duration based on the first ratio and the target increment.

[0226] Optionally, as an embodiment, the second determining module 530 is specifically used to: if the vehicle has a ventilation requirement and the target requirement level is greater than the preset requirement level, determine the ventilation duration of the vehicle based on the target requirement level; wherein the ventilation duration is negatively correlated with the target requirement level.

[0227] Optionally, as an embodiment, the control module 540 is specifically used to: control the vehicle to ventilate based on the ventilation duration through a target control method; wherein the target control method includes at least one of the following: controlling the air conditioner to operate in a target blowing mode, the vehicle's blower to operate at maximum air volume, the vehicle's air conditioner temperature damper to be in a cold air state, the vehicle's air conditioner compressor to be in a closed state, and the vehicle to be in an external circulation mode.

[0228] Optionally, as an embodiment, it further includes a heating module and a third determining module. The third determining module is used to: if the target demand level indicates that the vehicle has a heating demand, determine whether the vehicle meets the preset conditions; wherein, the preset conditions include a preset cabin temperature greater than a first threshold, or the vehicle's heating mode is the target heating mode.

[0229] The heating module is used to: heat the vehicle cabin through the vehicle's heat pump air conditioner and the vehicle's thermistor if the vehicle meets the preset conditions; and heat the vehicle cabin through the vehicle's heat pump air conditioner if the vehicle does not meet the preset conditions.

[0230] It should be noted that the aforementioned vehicle air conditioning control device is embodied in the form of a functional unit. The term "module" here can be implemented in software and / or hardware, without specific limitations.

[0231] For example, a "module" can be a software program, a hardware circuit, or a combination of both that implements the above functions. The hardware circuit may include an application-specific integrated circuit (ASIC), electronic circuits, a processor (e.g., a shared processor, a proprietary processor, or a group processor) and memory for executing one or more software or firmware programs, integrated logic circuits, and / or other suitable components that support the described functions.

[0232] Therefore, the units of the various examples described in the embodiments of this application can be implemented in electronic hardware, or a combination of computer software and electronic hardware. Whether these functions are implemented in hardware or software depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of this application.

[0233] Figure 6 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application.

[0234] For example, vehicle 600 includes processor 610, memory 620 and executable program code 630.

[0235] For example, vehicle 600 includes one or more processors 610 that can support vehicle 600 in implementing the vehicle air conditioning control method in the method embodiment. The processor 610 can be a general-purpose processor or a special-purpose processor. For example, the processor 610 can be a central processing unit (CPU), a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or other programmable logic devices, such as discrete gates, transistor logic devices, or discrete hardware components.

[0236] For example, the processor 610 can be used to control the vehicle 600, execute software programs, and process data from the software programs. The vehicle 600 may also include a communication unit for receiving and transmitting signals.

[0237] For example, the vehicle 600 may include one or more memories 620, on which executable program code 630 is stored. The executable program code 630 can be run by the processor 610 to generate instructions, causing the processor 610 to execute the vehicle air conditioning control method described in the above method embodiments according to the instructions.

[0238] Optionally, the memory 620 may also store data.
