Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a vehicle air conditioning control method, device, electronic device, and storage medium. Background Technology

[0002] With the development of new energy vehicles, pure electric and hybrid models are becoming increasingly mainstream, and range is one of the important indicators. When new energy vehicles are driven in pure electric mode, the air conditioning heating mainly relies on electric heating (except for models with heat pump configurations), such as water heating and PTC air heating, which have very low energy efficiency. Therefore, air conditioning heating has become one of the important factors affecting range. In addition, in spring and autumn, in addition to meeting the temperature comfort requirements, the interior of the car also needs to dehumidify and prevent fogging.

[0003] In existing technology, the air must first pass through the evaporator of the air conditioner to cool down and reduce the humidity inside the vehicle to achieve dehumidification. After being cooled, the air is heated by the heater before being blown out. The air needs to be cooled down and then heated up, which consumes a lot of electrical energy and thus affects the vehicle's range. Summary of the Invention

[0050] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0051] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0052] The user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0053] In spring and autumn, the outside air humidity is lower than in summer, except on rainy days. The main purpose of turning on the air conditioner compressor is to dehumidify and prevent fogging. The evaporator temperature is relatively low. According to the principle of the air conditioner housing, in order to ensure the temperature inside the car, the air conditioner recirculates air through the evaporator to cool it down before being heated. This increases the actual power consumption of the air conditioner and affects the overall vehicle range.

[0054] For example, if the outside temperature is 15°C, and the automatic air conditioning system calculates that the air outlet temperature needs to be 20°C, the blower will run, the compressor will start, and the system will switch to external circulation. The 15°C air will first be cooled to below 10°C by the evaporator, and then heated to 20°C by the heater (either a PTC air heater or a PTC water heater) to meet the comfort temperature requirements of the automatic air conditioning system in the vehicle.

[0055] In view of this, this application provides a vehicle air conditioning control method, which first obtains the wiper status and compressor status of the vehicle; determines the current fogging risk value based on the wiper status and compressor status; updates the compressor status based on the fogging risk value to obtain the updated compressor status; and controls the compressor based on the updated compressor status, wherein the air conditioning compressor can be turned off or indirectly turned on, which can reduce the air conditioning cooling power and achieve the effect of energy saving.

[0056] Figure 1 An application scenario diagram provided for an embodiment of this application, such as... Figure 1 As shown, the air conditioning controller can be connected to a wiper status sensor and a compressor status sensor. The wiper status sensor sends the wiper status to the air conditioning controller, and the compressor status sensor sends the compressor status to the air conditioning controller. The air conditioning controller determines the current fogging risk value based on the compressor status and wiper status, updates the compressor status based on the current fogging risk value, and then controls the compressor based on the updated compressor status.

[0057] The vehicle air conditioning control method provided in this application first obtains the vehicle's wiper status and compressor status; determines the current fogging risk value based on the wiper status and compressor status; updates the compressor status based on the fogging risk value to obtain the updated compressor status. In other words, the updated compressor status is determined based on the fogging risk value. The compressor is turned on when the fogging risk value is high and turned off when the fogging risk value is low. The compressor is controlled based on the updated compressor status. The air conditioning compressor can be turned off or turned on indirectly, which can reduce the air conditioning cooling power and achieve energy saving.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will be described below with reference to the accompanying drawings.

[0059] Figure 2 This is a flowchart illustrating a vehicle air conditioning control method provided in an embodiment of this application. The executing entity in this embodiment can be any device with data processing capabilities; however, this application uses an air conditioning controller (CCM) as the executing entity for specific description. Figure 2 As shown in the embodiments of this application, a vehicle air conditioning control method may include:

[0060] Step 201: Obtain the vehicle's windshield wiper status and compressor status.

[0061] Specifically, when a user unlocks their vehicle, connects to high-voltage power, or turns on the automatic air conditioning, the air conditioning controller first obtains the status of the vehicle's windshield wipers and compressor.

[0062] Optionally, the wiper status and compressor status of the vehicle can be obtained, including: in energy-saving mode, the wiper status and compressor status of the vehicle can be obtained.

[0063] The vehicle air conditioning control method provided in this application also includes: in response to an energy-saving mode shutdown command, determining whether the outside temperature is greater than a preset temperature;

[0064] When the outside temperature is greater than the preset temperature and the compressor is off, the compressor is turned on.

[0065] Specifically, in energy-saving mode, the air conditioning controller obtains the status of the vehicle's wipers and compressor. Users can enter energy-saving mode by clicking the energy-saving button on the multimedia screen's air conditioning interface, pressing the energy-saving mode button on the vehicle, or the air conditioning automatically entering energy-saving mode when the whole vehicle enters energy-saving mode. This application does not limit the method of entering energy-saving mode.

[0066] Furthermore, when the air conditioning controller receives the command to turn off the energy-saving mode, it can determine whether the outside temperature is greater than the preset temperature, and turn on the compressor when the outside temperature is greater than the preset temperature and the compressor is off.

[0067] For example, the preset temperature can be 3 degrees Celsius. When the outside temperature is greater than 3 degrees Celsius, it is determined to be a spring or autumn operating condition, which requires dehumidification and anti-fogging. When the compressor is in the off state, the compressor is turned on.

[0068] The vehicle air conditioning control method provided in this application can also determine whether the outside temperature is greater than a preset outside temperature. The preset outside temperature can be 22 degrees Celsius. When the outside temperature is greater than the preset outside temperature, the internal circulation mode is turned on. When the outside temperature is less than the preset outside temperature, the external circulation mode is turned on. This can improve the efficiency of defogging while saving energy.

[0069] In this way, if the outside temperature is higher than the preset temperature after the energy-saving mode is turned off, it is determined that the current scenario is spring and autumn conditions, which require dehumidification and anti-fogging. The compressor is then turned on even when the compressor is off, thus improving the user experience.

[0070] Step 202: Determine the current fogging risk value based on the wiper status and the compressor status.

[0071] Optionally, determining the current fogging risk value based on the wiper status and the compressor status includes:

[0072] When the wipers are off and the compressor is on, the fogging risk value is determined to be the first fogging risk value.

[0073] When the wipers are on and the compressor is on, the fogging risk value is determined to be the second fogging risk value.

[0074] When the windshield wipers are not turned on and the compressor is not turned on, the fogging risk value is determined to be the third fogging risk value;

[0075] When the wipers are on and the compressor is off, the fogging risk value is determined to be the fourth fogging risk value.

[0076] Specifically, the current fogging risk can be divided into four levels based on the status of the wipers and the compressor, as follows: when the wipers are off and the compressor is on, the fogging risk level is determined to be Level 1; when the wipers are on and the compressor is on, the fogging risk level is determined to be Level 2; when the wipers are off and the compressor is off, the fogging risk level is determined to be Level 3; and when the wipers are on and the compressor is off, the fogging risk level is determined to be Level 4.

[0077] Among them, the fog risk value corresponding to Level 1 is the first fog risk value, the fog risk value corresponding to Level 2 is the second fog risk value, the fog risk value corresponding to Level 3 is the third fog risk value, and the fog risk value corresponding to Level 4 is the fourth fog risk value. As the level increases, the corresponding fog risk value gradually increases.

[0078] The air conditioning controller determines the level of fogging risk based on the wiper status and compressor status, and then determines the current fogging risk value based on the level.

[0079] By setting a corresponding fogging risk value for each combination of wiper and compressor status, the efficiency and accuracy of the determined fogging risk value can be improved.

[0080] Step 203: Update the compressor status according to the fogging risk value to obtain the updated compressor status.

[0081] Optionally, the vehicle's wiper status and compressor status can be obtained, including: obtaining the vehicle's wiper status and compressor status at preset intervals.

[0082] The step of determining the current fogging risk value based on the wiper status and the compressor status includes: determining the fogging risk value for the current period from a plurality of preset fogging risk values ​​based on the wiper status and the compressor status;

[0083] The step of updating the compressor status based on the fogging risk value to obtain the updated compressor status includes: obtaining the reference fogging risk value of the previous period; increasing or decreasing the reference fogging risk value of the previous period by a preset step size based on the fogging risk value of the current period to obtain the reference fogging risk value of the current period; and updating the compressor status based on the reference fogging risk value of the current period.

[0084] The preset step size is less than the difference between two adjacent preset fogging risk values.

[0085] Specifically, at preset intervals, the air conditioning controller acquires the vehicle's wiper and compressor status. Based on these statuses and a mapping table, it determines the fogging risk value for the current period from multiple preset fogging risk values. The mapping table indicates the correspondence between the combination of wiper and compressor statuses and the preset fogging risk values. The difference between any two adjacent preset fogging risk values ​​is the same.

[0086] The air conditioning controller obtains the reference fogging risk value of the previous period, and adjusts the reference fogging risk value of the previous period based on the fogging risk value of the current period to obtain the reference fogging risk value of the current period. The specific adjustment method is to increase or decrease the reference fogging risk value of the previous period by a preset step size, such as performing low-pass filtering. The preset step size is smaller than the difference between two adjacent preset fogging risk values.

[0087] The compressor status is updated based on the reference fogging risk value obtained for the current cycle.

[0088] In this way, when updating the compressor status, it is based not only on the fogging risk value of the current cycle, but also on the reference fogging risk value of the previous cycle. By increasing or decreasing the reference fogging risk value of the previous cycle by a preset step size, the reference fogging risk value of the current cycle can be obtained. This allows the reference fogging risk value to change slowly. Then, the compressor status is updated based on the reference fogging risk value of the current cycle, avoiding the frequent start-up and shutdown of the compressor caused by the reference fogging risk value changing too quickly.

[0089] Optionally, based on the fogging risk value of the current period, the reference fogging risk value of the previous period is increased or decreased by a preset step size to obtain the reference fogging risk value of the current period, including:

[0090] When the reference fogging risk value of the previous period is greater than the fogging risk value of the current period, the step size is reduced based on the reference fogging risk value of the previous period to obtain the reference fogging risk value of the current period.

[0091] When the reference fogging risk value of the previous period is less than the fogging risk value of the current period, the step size is increased based on the reference fogging risk value of the previous period to obtain the reference fogging risk value of the current period.

[0092] Specifically, the air conditioning controller compares the reference fogging risk value of the previous period with the fogging risk value of the current period. If the reference fogging risk value of the previous period is greater than the fogging risk value of the current period, the reference fogging risk value of the previous period is reduced by a preset step size to obtain the reference fogging risk value of the current period. If the reference fogging risk value of the previous period is less than the fogging risk value of the current period, the reference fogging risk value of the previous period is increased by a preset step size to obtain the reference fogging risk value of the current period. If the reference fogging risk value of the previous period is equal to the fogging risk value of the current period, then the reference fogging risk value of the current period is either the reference fogging risk value of the previous period or the fogging risk value of the current period.

[0093] The following example, which uses the current fogging risk value as the basis for determining the compressor's status, illustrates the potential problems.

[0094] Assuming the current fogging risk value is greater than 0.7, the compressor status will be updated to "on"; if the current fogging risk value is less than 0.7, the compressor status will be updated to "off". In the current cycle, the wipers are on (the wiper sensor malfunctions, the actual wiper status is off), and the compressor is off. Looking up the mapping table, the current fogging risk value is 0.8, so the compressor status is updated to "on". In the next cycle, the wipers are off (the wiper sensor detects correctly), and the compressor is on. If the fogging risk value for the next cycle is determined to be 0.2, the compressor status will be updated to "off". In other words, the compressor experiences on and off cycles within two cycles. This frequent on / off switching of the compressor is highly damaging.

[0095] In the same situation as above, the current fogging risk value is determined to be 0.8. Using the method of this application, the reference fogging risk value of the previous cycle needs to be referenced, let's say it's 0.6. Since 0.8 is greater than 0.6, a preset step size needs to be added to 0.6, let's say it's 0.05, to obtain the reference fogging risk value of the current cycle as 0.65. The compressor status does not need to change. In the next cycle, the wipers are on and the compressor is on. The fogging risk value of the next cycle is determined to be 0.2. Since 0.2 < 0.65, the preset step size needs to be reduced from 0.65 to obtain the reference fogging risk value of the next cycle as 0.6. The compressor status does not need to change. In other words, using the method of this application, the compressor status does not need to change, avoiding situations where the current fogging risk value changes too much between adjacent cycles, wiper sensor or compressor sensor detection errors, or the compressor frequently starts and stops due to the wipers only being on for a very short time, thus extending the compressor's lifespan.

[0096] Optionally, the compressor status is updated based on the reference fogging risk value for the current period, including:

[0097] Obtain the target head temperature and actual head temperature of the vehicle in the current cycle;

[0098] The compressor status is updated based on the reference fogging risk value, target head temperature, and actual head temperature for the current cycle.

[0099] In this way, when updating the compressor status, not only the reference fogging risk value for the current cycle is considered, but also the target head temperature and the actual head temperature are taken into account, so that the updated compressor status not only meets the requirements for defogging, but also meets the requirements for temperature comfort.

[0100] Optionally, the compressor status is updated based on the reference fogging risk value, target head temperature, and actual head temperature for the current period, including:

[0101] When the reference fogging risk value for the current cycle is greater than the first preset risk value, and / or the difference between the target head temperature and the actual head temperature is greater than the first preset difference, the compressor status is updated to "on".

[0102] When the reference fogging risk value for the current cycle is less than the second preset risk value and the difference is less than the second preset difference, the compressor status is updated to off.

[0103] The first preset risk value can be 30%, the second preset risk value can be 25%, the first preset difference is 2 degrees Celsius, and the second preset difference is 1 degree Celsius.

[0104] Specifically, the air conditioning controller calculates the difference between the target head temperature and the actual head temperature, and compares the calculated difference with the first preset difference and the second preset difference, and compares the reference fogging risk value, the first preset risk value and the second preset risk value for the current cycle.

[0105] If the reference fogging risk value for the current cycle is greater than the first preset risk value, the compressor status will be updated to "on".

[0106] When the difference between the target head temperature and the actual head temperature is greater than the first preset difference, the compressor status will be updated to "on".

[0107] When the reference fogging risk value for the current cycle is greater than the first preset risk value and the difference between the target head temperature and the actual head temperature is greater than the first preset difference, the compressor status will be updated to "on".

[0108] When the reference fogging risk value for the current cycle is less than the second preset risk value and the difference between the target head temperature and the actual head temperature is less than the second preset difference, the compressor status is updated to off.

[0109] In all other cases, the compressor remains unchanged.

[0110] In this way, the compressor is turned off when both the current reference fogging risk value and the difference are less than the preset value, and the compressor is turned on when either the current reference fogging risk value or the difference is greater than the preset value, thus saving energy while ensuring the user's defogging and temperature requirements are met.

[0111] Optionally, obtain the target head temperature and actual head temperature of the vehicle in the current cycle, including:

[0112] The target head temperature is determined based on the outside temperature and the air conditioning setting.

[0113] The actual head temperature is determined based on the current interior temperature, sunlight intensity, exterior temperature, air conditioning vent temperature, and air conditioning vent airflow.

[0114] Specifically, the target head temperature is determined based on the outside temperature and the air conditioning setting, while the actual head temperature is determined based on the current inside temperature, sunlight intensity, outside temperature, air conditioning vent temperature, and airflow from the air conditioning vent.

[0115] This makes the determined target head temperature and actual head temperature more accurate.

[0116] Step 204: Control the compressor according to the updated compressor status.

[0117] Specifically, the air conditioning controller controls the compressor based on the updated compressor status.

[0118] This application provides a vehicle air conditioning control method, which first obtains the wiper status and compressor status of the vehicle; determines the current fogging risk value based on the wiper status and compressor status; updates the compressor status based on the fogging risk value to obtain an updated compressor status; and controls the compressor based on the updated compressor status, allowing the air conditioning compressor to be turned off or indirectly turned on, saving approximately 1kW of air conditioning power. This achieves energy saving of the air conditioning while dehumidifying and preventing fogging, thereby improving the driving range of new energy vehicles.

[0119] Figure 3 A schematic flowchart of another vehicle air conditioning control method provided in this application embodiment is shown below. Figure 3 As shown, when the vehicle is unlocked, the high voltage is applied, or the automatic air conditioning is turned on, the air conditioning controller initializes the automatic air conditioning, determining the outside temperature, the air conditioning set temperature, the inside temperature, the sunlight intensity, the air conditioning vent temperature, the air conditioning vent air volume, the wiper status, and the compressor status.

[0120] Determine if the outside temperature is below 22°C. If it is, turn on the air conditioning with the external air circulation mode. If it is above 22°C, turn on the air conditioning with the internal air circulation mode.

[0121] The target head temperature is calculated based on the outside temperature and the air conditioning set temperature. The actual head temperature is calculated based on the outside temperature, inside temperature, sunlight intensity, air conditioning vent temperature, and air conditioning vent airflow. The difference between the target head temperature and the actual head temperature is then calculated.

[0122] The current fogging risk level is determined based on the status of the wipers and the compressor. The specific judgment method is as follows: when the wipers are off and the compressor is on, the current fogging risk level is Level 1; when the wipers are on and the compressor is on, the current fogging risk level is Level 2; when the wipers are off and the compressor is off, the current fogging risk level is Level 3; when the wipers are on and the compressor is off, the current fogging risk level is Level 4. Levels 1 to 4 correspond to different current fogging risk values, and the current fogging risk value gradually increases with the increase of the level.

[0123] Based on the determined fog risk level, the current fog risk value can be determined. The current fog risk value is compared with the reference fog risk value of the previous period. Based on the comparison result, the reference fog risk value of the previous period is subjected to low-pass filtering to determine the reference fog risk value of the current period. The low-pass filtering process involves increasing or decreasing a preset step size based on the reference fog risk value of the previous period.

[0124] While initializing the automatic air conditioner, it checks whether the energy-saving mode is activated. If the energy-saving mode is not activated, the compressor is turned on. If the energy-saving mode is activated, it determines whether the compressor should be turned on based on the reference fogging risk value for the current period and the difference between the target head temperature and the actual head temperature. The compressor is turned on when the reference fogging risk value for the current period is greater than 30% or the difference between the target head temperature and the actual head temperature is greater than 2°C. The compressor is turned off when the reference fogging risk value for the current period is less than 25% and the difference between the target head temperature and the actual head temperature is less than 1°C. The compressor status is updated in real time based on the current compressor status.

[0125] Corresponding to the above-described vehicle air conditioning control method, this application also provides a vehicle air conditioning control device. Figure 4 This is a schematic diagram of the structure of a vehicle air conditioning control device provided in an embodiment of this application. Figure 4 As shown, the device includes:

[0126] The acquisition module 401 is used to acquire the status of the vehicle's windshield wipers and compressor.

[0127] The determining module 402 is used to determine the current fogging risk value based on the wiper status and the compressor status;

[0128] The update module 403 is used to update the compressor status according to the fogging risk value to obtain the updated compressor status;

[0129] The control module 404 is used to control the compressor according to the updated compressor status.

[0130] Optionally, module 401 is specifically used to: acquire the wiper status and compressor status of the vehicle at preset intervals;

[0131] The determining module 402 is specifically used to: determine the fogging risk value for the current cycle from multiple preset fogging risk values ​​based on the wiper status and the compressor status;
