Description

Technical Field

[0001] This application relates to the field of automotive air conditioning technology, and more specifically, to a temperature control method, device, storage medium, and equipment. Background Technology

[0002] With the rapid development of automotive technology, cars have become an important means of transportation in people's daily lives. To meet the different temperature requirements of different locations inside the car, the interior space is usually divided into several temperature zones, each of which can be independently adjusted. Current multi-zone climate control systems generally use at least two in-vehicle temperature sensors for closed-loop control. However, multiple independent sensors are costly, and due to installation environment limitations, the sampled values ​​from the in-vehicle temperature sensors cannot accurately represent the actual temperature of each zone, especially in complex and changing driving environments. Therefore, directly controlling the temperature of each zone based on sensor sampled values ​​is not precise enough and can easily affect the user experience of drivers and passengers. Summary of the Invention

[0003] The purpose of this application is to provide a temperature control method, device, storage medium and equipment, which aims to solve the problems of high cost and insufficient control accuracy of temperature control methods in multi-temperature zone air conditioning systems in related technologies.

[0004] In a first aspect, this application provides a temperature control method, comprising: acquiring a sampled value of the vehicle interior temperature detected by a target temperature sensor; the target temperature sensor being disposed in the center of the vehicle interior; determining a temperature correction value corresponding to the target temperature zone based on the current vehicle speed, the outside temperature, and the air conditioning circulation status, the air outlet temperature, and the light intensity of the target temperature zone; the target temperature zone being any one of at least two temperature zones divided within the vehicle interior space; obtaining the head temperature corresponding to the target temperature zone based on the sampled value of the vehicle interior temperature and the temperature correction value, and performing temperature control on the target temperature zone based on the head temperature.

[0005] In the above implementation process, a single in-vehicle temperature sensor positioned in the center of the vehicle acquires sampled values ​​of the in-vehicle temperature. Based on the current vehicle speed, outside temperature, and the air conditioning circulation status, vent temperature, and light intensity of the target temperature zone, a temperature correction value corresponding to the target temperature zone is determined. Then, the in-vehicle temperature sampled values ​​are corrected based on this correction value to obtain the head temperature of the target temperature zone, which is then used for temperature control of that zone. This reduces the cost of the in-vehicle temperature sensor while improving the accuracy of temperature control for each temperature zone.

[0006] Furthermore, in some examples, the temperature correction value corresponding to the target temperature zone includes a first correction value, a second correction value, a third correction value, and a fourth correction value; the first correction value represents the correction of the vehicle interior temperature of the target temperature zone by the outside temperature; the second correction value represents the correction of the head temperature of the target temperature zone by the outside temperature; the third correction value represents the correction of the head temperature of the target temperature zone by the air outlet temperature; and the fourth correction value represents the correction of the head temperature of the target temperature zone by sunlight.

[0007] In the above implementation process, the temperature correction value corresponding to the target temperature zone consists of four parts: the correction of the vehicle interior temperature by the outside temperature, the correction of the head temperature by the outside temperature, the correction of the head temperature by the air outlet temperature, and the correction of the head temperature by the light. Through these four parts of correction, a more accurate head temperature can be obtained.

[0008] Further, in some examples, determining the temperature correction value corresponding to the target temperature zone based on the current vehicle speed, outside temperature, and the air conditioning circulation status, outlet air temperature, and light intensity of the target temperature zone includes: when the air conditioning circulation status of the target temperature zone is recirculation, determining that both the first correction value and the second correction value are zero; when the air conditioning circulation status of the target temperature zone is not recirculation, consulting the first calibration table and the second calibration table respectively based on the current vehicle speed and outside temperature to obtain the first correction factor and the second correction factor, then multiplying the first correction factor by the circulation ratio coefficient to obtain the first correction value, and multiplying the second correction factor by the circulation ratio coefficient to obtain the second correction value; calculating the difference between the average outlet air temperature of the target temperature zone and the sampled value of the vehicle interior temperature, consulting the third calibration table based on the difference to obtain the third correction value; consulting the fourth calibration table based on the light intensity of the target temperature zone and the current vehicle speed to obtain the sunlight compensation value, consulting the fifth calibration table based on the outside temperature to obtain the outside temperature coefficient, and multiplying the sunlight compensation value and the outside temperature coefficient to obtain the fourth correction value.

[0009] In the above implementation process, a specific method is provided for obtaining the temperature correction value corresponding to the target temperature zone.

[0010] Furthermore, in some examples, the average air outlet temperature is calculated by weighting the air outlet temperatures of the window vent, the face vent, and the feet vent, along with the corresponding window vent ratio, face vent ratio, and feet vent ratio.

[0011] In the above process, the weighted average outlet air temperature is obtained based on the proportion of air blowing through the window, the proportion of air blowing through the face, and the proportion of air blowing through the feet, which is helpful for accurately estimating the correction of the head temperature by the outlet air temperature.

[0012] Furthermore, in some examples, the light intensity of the target temperature zone is the product of the solar irradiance coefficient and the light intensity of the target temperature zone; the solar irradiance coefficient is obtained by consulting the sixth calibration table based on the solar altitude angle and the vehicle's orientation; the solar altitude angle is obtained based on weather forecast applications; the vehicle's orientation is obtained based on a navigation system; and the light intensity is obtained based on a light intensity sensor.

[0013] In the above implementation process, a specific method for obtaining the light intensity of the target temperature zone is provided.

[0014] Furthermore, in some examples, before obtaining the head temperature corresponding to the target temperature zone based on the in-vehicle temperature sampling value and the temperature correction value, the method includes: performing a first-order low-pass filter on the in-vehicle temperature sampling value to obtain the filtered in-vehicle temperature.

[0015] In the above implementation process, by performing first-order low-pass filtering on the sampled values ​​of the vehicle interior temperature, noise in the acquisition signal of the target temperature sensor can be filtered out, thereby improving the measurement accuracy of the vehicle interior temperature.

[0016] Furthermore, in some examples, obtaining the head temperature corresponding to the target temperature zone based on the in-vehicle temperature sampling value and the temperature correction value includes: adding the filtered in-vehicle temperature and the temperature correction value, and determining the summed value as the head temperature corresponding to the target temperature zone.

[0017] In the above implementation process, the head temperature corresponding to the target temperature zone can be obtained by adding the filtered in-vehicle temperature to the calculated temperature correction value. This makes the calculated head temperature more accurately represent the actual temperature of the corresponding temperature zone.

[0018] Secondly, this application provides a temperature control device, comprising: an acquisition module for acquiring a sampled value of the vehicle interior temperature detected by a target temperature sensor; the target temperature sensor being disposed in the center of the vehicle interior; a determination module for determining a temperature correction value corresponding to the target temperature zone based on the current vehicle speed, the outside temperature, and the air conditioning circulation status, air outlet temperature, and light intensity of the target temperature zone; the target temperature zone being any one of at least two temperature zones divided within the vehicle interior space; and a control module for obtaining the head temperature corresponding to the target temperature zone based on the sampled value of the vehicle interior temperature and the temperature correction value, and performing temperature control on the target temperature zone based on the head temperature.

[0019] Thirdly, this application provides an electronic device comprising: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor, when executing the computer program, implements the steps of the method described in any of the first aspects.

[0020] Fourthly, this application provides a computer-readable storage medium storing instructions that, when executed on a computer, cause the computer to perform the method described in any of the first aspects.

[0021] Fifthly, this application provides a computer program product that, when run on a computer, causes the computer to perform the method described in any of the first aspects.

[0029] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0030] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the description of this application, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] As described in the background section, the temperature control methods of multi-zone air conditioning systems in related technologies suffer from high costs and insufficient control precision. Therefore, this application provides a new temperature control scheme to solve the aforementioned problems.

[0032] The embodiments of this application will be described below:

[0033] like Figure 1 As shown, Figure 1 This is a flowchart illustrating a temperature control method provided in an embodiment of this application. The method can be applied to the electronic control unit (ECU) of a dual-temperature zone or multi-temperature zone air conditioning system.

[0034] The method includes:

[0035] Step 101: Obtain the vehicle interior temperature sampling value detected by the target temperature sensor; the target temperature sensor is located in the center of the vehicle interior.

[0036] The target temperature sensor mentioned in this step is a temperature sensor located in the center of the vehicle interior. This target temperature sensor can be an NTC (Negative Temperature Coefficient) thermistor or other types of temperature sensors. In this embodiment, the target temperature sensor is connected to the ECU of the control system and provides signals to the ECU. The ECU then uses an algorithm to correct the vehicle interior temperature sampling values ​​detected by the target temperature sensor to the head temperature of each temperature zone, thereby achieving independent closed-loop control of multiple temperature zones.

[0037] Step 102: Determine the temperature correction value corresponding to the target temperature zone based on the current vehicle speed, outside temperature, air conditioning circulation status, air outlet temperature, and light intensity of the target temperature zone; the target temperature zone is any one of at least two temperature zones divided within the vehicle interior space.

[0038] This embodiment uses parameters such as current vehicle speed, outside temperature, air conditioning circulation status, air outlet temperature, and light intensity to determine the correction value of the head temperature in the target temperature zone. Since these parameters can be obtained from the vehicle's existing sensors, the correction of the in-vehicle temperature sampling value can be achieved without adding any new automotive hardware. This allows for precise temperature control of multiple temperature zones by reducing the number of in-vehicle temperature sensors.

[0039] In some embodiments, the temperature correction value corresponding to the target temperature zone mentioned in this step may include a first correction value, a second correction value, a third correction value, and a fourth correction value. The first correction value represents the correction of the vehicle interior temperature of the target temperature zone by the outside temperature; the second correction value represents the correction of the head temperature of the target temperature zone by the outside temperature; the third correction value represents the correction of the head temperature of the target temperature zone by the air outlet temperature; and the fourth correction value represents the correction of the head temperature of the target temperature zone by sunlight. In other words, the temperature correction value corresponding to the target temperature zone can be composed of four corrections: the correction of the vehicle interior temperature by the outside temperature, the correction of the head temperature by the outside temperature, the correction of the head temperature by the air outlet temperature, and the correction of the head temperature by sunlight. In practical applications, the head temperature inside the vehicle is affected by the heat radiation from the windshield and sunroof, sunlight intensity, and air outlet temperature. Therefore, experiments have shown that a more accurate head temperature can be obtained through these four corrections.

[0040] Further, in some embodiments, this step may include: when the air conditioning circulation state of the target temperature zone is recirculation, determining that both the first correction value and the second correction value are zero; when the air conditioning circulation state of the target temperature zone is not recirculation, querying the first calibration table and the second calibration table according to the current vehicle speed and the outside temperature respectively to obtain the first correction factor and the second correction factor, then multiplying the first correction factor by the circulation ratio coefficient to obtain the first correction value, and multiplying the second correction factor by the circulation ratio coefficient to obtain the second correction value; calculating the difference between the average outlet air temperature of the target temperature zone and the sampled value of the vehicle interior temperature, querying the third calibration table according to the difference to obtain the third correction value; querying the fourth calibration table according to the light intensity of the target temperature zone and the current vehicle speed to obtain the sunlight compensation value, querying the fifth calibration table according to the outside temperature to obtain the outside temperature coefficient, and multiplying the sunlight compensation value and the outside temperature coefficient to obtain the fourth correction value.

[0041] In other words, regarding the correction of the vehicle interior temperature based on the outside temperature, if the air conditioning circulation mode in the target temperature zone is recirculation, the correction is 0. If it is not recirculation, the correction is obtained by consulting the first calibration table based on the outside temperature and the current vehicle speed to obtain the first correction factor, and then multiplying it by the circulation ratio coefficient. The first calibration table records the correction factors for the vehicle interior temperature under different operating conditions composed of different outside temperatures and different vehicle speeds.

[0042] Regarding the correction for head temperature based on outside temperature, similarly, if the air conditioning circulation in the target temperature zone is in recirculation mode, the correction is 0. If it is not in recirculation mode, the correction is obtained by consulting the second calibration table based on the outside temperature and current vehicle speed to obtain a second correction factor, which is then multiplied by the circulation ratio coefficient. This second calibration table records the correction factors for head temperature under different outside temperatures and different vehicle speeds. Furthermore, when the air intake in the target temperature zone does not pass through the recirculation damper, the correction for the interior temperature of the target temperature zone based on outside temperature is 0, and the correction for the head temperature based on outside temperature is also 0.

[0043] The correction for head temperature based on air outlet temperature is obtained by consulting a third calibration table, which is the difference between the average air outlet temperature of the target temperature zone and the sampled interior temperature value. The average air outlet temperature of the target temperature zone can be obtained from the air outlet temperatures of each vent. Generally, air outlets in an air conditioning system include window vents, face vents, and foot vents. Therefore, the average air outlet temperature can be calculated by weighting the air outlet temperatures from the window, face, and foot vents according to their respective proportions. This yields a weighted average air outlet temperature based on these proportions. The third calibration table records the correction values ​​for head temperature based on different temperature differences, which are the difference between the average air outlet temperature of the target temperature zone and the sampled interior temperature value. Therefore, by consulting the third calibration table, the correction for head temperature based on air outlet temperature can be obtained.

[0044] The correction for head temperature caused by sunlight is obtained by multiplying the sunlight compensation value and the external temperature coefficient. The sunlight compensation value is obtained by consulting the fourth calibration table based on the sunlight intensity of the target temperature zone and the current vehicle speed. This fourth calibration table records the sunlight compensation values ​​for head temperature under different sunlight intensities and vehicle speeds. The external temperature coefficient is obtained by consulting the fifth calibration table based on the outside temperature. This fifth calibration table records the external temperature coefficients corresponding to different outside temperatures, and the external temperature coefficient ranges from 0 to 1. Optionally, the sunlight intensity of the target temperature zone can be the product of the solar oblique angle coefficient and the light intensity of that target temperature zone. The solar oblique angle coefficient is obtained by consulting the sixth calibration table based on the solar altitude angle and the vehicle's heading. The solar altitude angle is based on weather forecasts; the vehicle's heading is based on the navigation system; and the light intensity is based on a light intensity sensor. In other words, in implementation, the ECU can calculate the sunlight intensity for each temperature zone based on the solar altitude angle from the weather forecast, the vehicle's heading angle from the navigation information, and the left and right light intensities fed back by the light intensity sensor. The light intensity here refers to the sampled value from the light intensity sensor, which typically includes left and right light intensities. In practice, the driver's side, including the temperature zones of the driver's seat, middle left, and third row left, uses the left light intensity in the calculations. The passenger side, including the temperature zones of the passenger seat, middle right, and third row right, uses the right light intensity. The solar altitude angle here represents the angle between the direction of sunlight incident at a location on Earth and the horizontal plane, defined as 0 to 90°. The vehicle's facing angle here represents the direction the vehicle is facing. When the solar altitude angle is within a certain range, different vehicle facing directions will result in different effects of celestial radiation on head temperature. Therefore, based on the solar altitude angle and vehicle facing direction, a solar oblique coefficient can be obtained from a table. Combined with vehicle speed, the impact of celestial radiation on head temperature under different vehicle speeds and light conditions can be estimated and corrected.

[0045] Furthermore, in this embodiment, the current vehicle speed can be obtained from the navigation system; the outside temperature can be detected by an outside temperature sensor or obtained from a weather forecast application; and the air outlet temperature of each vent can be detected by an air outlet temperature sensor installed at the corresponding vent. Additionally, the calibration tables mentioned earlier can be established by placing thermocouples in the head area of ​​each temperature zone, then calibrating and adjusting each correction value on a real vehicle to make the corrected head temperature close to the thermocouple value.

[0046] Step 103: Based on the in-vehicle temperature sampling value and the temperature correction value, obtain the head temperature corresponding to the target temperature zone, and perform temperature control on the target temperature zone based on the head temperature.

[0047] This step refers to: based on discrete in-vehicle temperature sampling values, correcting them using temperature correction values ​​to obtain the corrected head temperature. Then, the ECU uses the corrected head temperature to control each temperature zone in a closed loop, making the temperature control of each temperature zone more precise.

[0048] In some embodiments, prior to this step, the system may perform a first-order low-pass filter on the sampled in-vehicle temperature values ​​to obtain a filtered in-vehicle temperature. A first-order low-pass filter, also known as a first-order inertial filter, uses a weighted average of the current sampled value and the previous filtered output value to obtain an effective filtered value, allowing the output to provide feedback to the input. By performing a first-order low-pass filter on the in-vehicle temperature sampled values, noise in the target temperature sensor's acquisition signal can be filtered out, improving the measurement accuracy of the in-vehicle temperature and facilitating precise control of the temperature in each temperature zone. Furthermore, the ECU can also perform a first-order low-pass filter on the sensor sampled values ​​for the other sensor parameters involved in step 102.

[0049] Furthermore, in some embodiments, obtaining the head temperature corresponding to the target temperature zone based on the sampled in-vehicle temperature and the temperature correction value mentioned in this step may include: adding the filtered in-vehicle temperature and the temperature correction value, and determining the summed value as the head temperature corresponding to the target temperature zone. In other words, the head temperature corresponding to the target temperature zone can be obtained by adding the filtered in-vehicle temperature and the calculated temperature correction value. This makes the calculated head temperature more accurately represent the actual temperature of the corresponding temperature zone.

[0050] In this embodiment, a target temperature sensor positioned in the center of the vehicle interior acquires sampled interior temperature values. Based on the current vehicle speed, outside temperature, and the air conditioning circulation status, vent temperature, and light intensity of the target temperature zone, a temperature correction value is determined for that zone. This correction value is then used to adjust the sampled interior temperature values, yielding the head temperature of the target zone, which is then used for temperature control. This approach reduces the cost of the interior temperature sensor while improving the accuracy of temperature control across all zones.

[0051] To provide a more detailed explanation of the solution in this application, a specific embodiment is described below:

[0052] This embodiment provides a vehicle interior temperature correction scheme for multi-zone air conditioning. In this scheme, an interior temperature sensor is positioned in the center of the vehicle interior. An algorithm is used to correct the sampled values ​​to the head temperature for each zone, thereby achieving independent closed-loop control for multiple temperature zones. The workflow of this scheme is as follows: Figure 2 As shown, it includes:

[0053] S201. Obtain the sampled value of the vehicle interior temperature detected by the vehicle interior temperature sensor;

[0054] S202. Perform a first-order low-pass filter on the sampled values ​​of the vehicle interior temperature to obtain the filtered vehicle interior temperature.

[0055] S203. Obtain the current vehicle speed, outside temperature, air outlet temperature, and light intensity through other sensors on the vehicle.

[0056] S204. Perform first-order low-pass filtering on the obtained sensor sampling values;

[0057] S205. The corrections for the outside temperature to the inside temperature, the outside temperature to the head temperature, the air outlet temperature to the head temperature, and the light intensity to the head temperature are calculated respectively.

[0058] Specifically, regarding the correction of the vehicle interior temperature based on the outside temperature, when the air conditioning circulation mode of the target temperature zone is in recirculation, or when the air intake of the target temperature zone does not pass through the recirculation damper, the correction is 0. When the air conditioning circulation mode of the target temperature zone is not in recirculation, the correction is obtained by referring to Table 1 based on the outside temperature and vehicle speed to obtain the first correction factor, and then multiplying the first correction factor by the circulation ratio coefficient. Table 1 is the lookup table for the correction factor of the outside temperature on the inside temperature, and the contents of the table are as follows:

[0059] Table 1. Lookup table of correction factors for external temperature on internal temperature

[0060]

[0061]

[0062] Regarding the correction for head temperature based on outside temperature, the correction is 0 when the air conditioning circulation in the target temperature zone is in recirculation mode, or when the air intake in the target temperature zone does not pass through the recirculation damper. When the air conditioning circulation in the target temperature zone is not in recirculation mode, the correction is obtained by referring to Table 2 based on the outside temperature and vehicle speed to get a second correction factor, which is then multiplied by the circulation ratio coefficient. Table 2 is the lookup table for the correction factor of outside temperature on head temperature, and its contents are shown below:

[0063] Table 2. Lookup table of correction factors for head temperature based on external temperature.

[0064]

[0065] To correct for the impact of outlet air temperature on head temperature, the weighted average outlet air temperature is first calculated using the following formula:

[0066] T diff =T windshield *ω windshield +T panel *ωpanel +T floor *ω floor

[0067] In the formula, T diff T represents the average outlet air temperature. windshield The air outlet temperature at the window vent; T panel T is the outlet air temperature of the air blowing nozzle; floor The air outlet temperature of the foot blower; ω windshield ω represents the window blowing ratio; panel For the blowing ratio; ω floor The foot-blowing ratio is then calculated. The average outlet air temperature is then subtracted from the sampled interior temperature to obtain the temperature difference. Finally, if the air conditioning circulation in the target temperature zone is internal circulation, the correction of the outlet air temperature to the head temperature is obtained by looking up the temperature difference in Table 3. If the air conditioning circulation in the target temperature zone is external circulation, the correction of the outlet air temperature to the head temperature is obtained by looking up the temperature difference in Table 4.

[0068] Table 3 is a lookup table for the correction of the outlet air temperature to the head temperature under recirculation mode. The contents of the table are as follows:

[0069] Table 3. Lookup table for the correction of head temperature by outlet air temperature under recirculation mode.

[0070]

[0071] Table 4 is a lookup table for the correction of the outlet air temperature to the head temperature under external circulation mode. The contents of the table are as follows:

[0072] Table 4. Lookup table for the correction of head temperature by outlet air temperature under external circulation mode.

[0073]

[0074] To correct for the impact of sunlight on head temperature, the correction is based on the sunlight compensation value obtained from Table 5, which is derived from the sunlight intensity and vehicle speed in the target temperature zone. This compensation value is then multiplied by the external temperature coefficient. The sunlight intensity is calculated based on the solar altitude angle from the weather forecast, the vehicle's heading angle from the navigation information, and the left and right light intensities. Table 5 is a lookup table for the sunlight compensation value for head temperature. For ease of display, the light intensity is converted from the value collected by the light intensity sensor into a percentage. The contents of the table are shown below:

[0075] Table 5. Lookup table for sunlight's correction value for internal temperature

[0076]

[0077] The external temperature coefficient can be obtained by looking up Table 6, which is shown below:

[0078] Table 6. Lookup Table for External Temperature Coefficient

[0079]

[0080]

[0081] S206. Calculate the head temperature in the target temperature zone;

[0082] Wherein, the head temperature in the target temperature zone = filtered interior temperature + correction of interior temperature by exterior temperature / 2 + correction of head temperature by exterior temperature / 2 + correction of head temperature by air outlet temperature + correction of head temperature by light.

[0083] S207. Use the calculated head temperature to control the temperature of the target temperature zone.

[0084] This embodiment reduces the need for one in-vehicle temperature sensor. Furthermore, by correcting the in-vehicle temperature based on parameters from other vehicle sensors, it adjusts the head temperature to reflect the head temperature in each zone. The corrected head temperature is then used in a closed-loop control system to achieve accurate control of each zone. Additionally, by adjusting for vehicle speed and sunlight compensation, the impact of the sunroof on head temperature under different speeds and lighting conditions is estimated and corrected, thereby improving control precision.
