Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more specifically to a control method, control device, vehicle, and readable storage medium for vehicle air conditioning. Background Technology

[0002] Car air conditioning is used to regulate the temperature inside the vehicle to improve passenger comfort. The air conditioning system is controlled by adjusting the outside temperature using a calibration interpolation table. However, because this interpolation calibration relies on calibration experience, the temperature regulation effect is often poor, negatively impacting the passenger experience.

[0003] In related technologies, a method for adjusting the air outlet temperature is provided. Considering the impact of sunlight on the temperature inside the vehicle, a light intensity adjustment factor is added. The air outlet temperature is compensated according to the light intensity to improve the passenger experience.

[0004] In implementing the above embodiments, the following problems exist: using light intensity to compensate for the air outlet temperature results in a relatively limited adjustment of the air outlet temperature, and the control effect is often unsatisfactory, with little impact on the passenger experience. Summary of the Invention

[0005] One of the objectives of this invention is to provide a vehicle air conditioning control method, control device, vehicle, and readable storage medium to solve the problems of poor air outlet temperature regulation and poor passenger experience in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] In some technical solutions, a method for controlling a vehicle air conditioner is provided, including: acquiring the sunlight illuminance of the driver's side and the passenger's side; determining the driver's side temperature offset value and the passenger's side temperature offset value based on the sunlight illuminance of the driver's side and the passenger's side, and determining the solar radiation temperature of the driver's side and the passenger's side; acquiring a first base temperature of the driver's side and a second base temperature of the passenger's side; determining the driver's side air outlet temperature and the passenger's side air outlet temperature based on the first base temperature, the second base temperature, the driver's side temperature offset value, the passenger's side temperature offset value, the driver's side solar radiation temperature, and the passenger's side solar radiation temperature; and controlling the operation of the air conditioner based on the driver's side air outlet temperature and the passenger's side air outlet temperature.

[0008] The vehicle air conditioning control method disclosed herein determines the impact of sunlight illuminance on the vehicle interior temperature by acquiring the sunlight illuminance for the driver's side and the passenger's side. Specifically, the sunlight illuminance for the driver's side is used to determine the temperature impact on the driver's position, i.e., determining the driver's side temperature deviation value; and the sunlight illuminance for the passenger's side is used to determine the temperature impact on the passenger's position, i.e., determining the passenger's side temperature deviation value. Furthermore, considering the impact of solar radiation on the surface temperature of objects, the solar radiation temperature for the driver's side and the solar radiation temperature for the passenger's side are determined based on the sunlight illuminance for the driver's side. Further, based on the basic temperature requirements of the driver and passenger's sides—that is, based on the first and second basic temperatures—and combining the driver's side temperature deviation value, the passenger's side temperature deviation value, the solar radiation temperature for the driver's side, and the solar radiation temperature for the passenger's side, the driver's side air outlet temperature and the passenger's side air outlet temperature are determined separately. The air conditioning operation is controlled so that the air outlet temperature on the driver's side reaches the driver's side air outlet temperature, and the air outlet temperature on the passenger's side reaches the passenger's side air outlet temperature.

[0009] The vehicle control method disclosed herein takes into account the different effects of sunlight illuminance on the driver and passenger sides. It determines the driver's side temperature offset and solar radiation temperature by separately acquiring the sunlight illuminance on the driver's side. Similarly, it acquires the passenger's side sunlight illuminance and determines the passenger's side temperature offset and solar radiation temperature. Based on the baseline temperatures of the driver and passenger sides, it determines the target air outlet temperatures for both sides. This allows for control of the air conditioning system, adjusting the air outlet temperatures on both sides to effectively reduce temperature differences caused by uneven sunlight exposure, thereby improving the overall comfort of passengers inside the vehicle.

[0010] Furthermore, the steps for determining the driver's side temperature offset value and the passenger's side temperature offset value based on the driver's side sunlight illuminance and the passenger's side sunlight illuminance include: determining the light intensity weighting coefficient based on the driver's side sunlight illuminance and the passenger's side sunlight illuminance; determining the driver's side light temperature and the passenger's side light temperature based on the driver's side sunlight illuminance and the passenger's side sunlight illuminance and the light intensity weighting coefficient; and determining the driver's side temperature offset value and the passenger's side temperature offset value based on the driver's side light temperature and the passenger's side light temperature.

[0011] This technical solution assigns different weights to the driver's and passenger's sides based on varying lighting conditions, improving the accuracy of temperature regulation and more accurately reflecting the impact of light intensity on the vehicle's interior temperature. Furthermore, based on the sunlight intensity and light intensity weighting coefficients for the driver and passenger sides, the driver's and passenger's light temperatures are determined. Then, based on these light temperatures, the driver's and passenger's temperature offset values ​​are determined. In this way, by considering the potential differences in lighting on both sides of the vehicle, the temperatures on both sides are compensated separately, allowing the air conditioning vent temperature to adapt to different lighting conditions, thereby improving the temperature balance on both sides of the vehicle and avoiding significant temperature differences.

[0012] Furthermore, the steps for determining the light intensity weighting coefficient based on the sunlight illuminance of the driver's side and the passenger's side include: when the sunlight illuminance of the driver's side is equal to that of the passenger's side, determining the light intensity weighting coefficient H = 0.5; when the sunlight illuminance of the driver's side is not equal to that of the passenger's side, determining the light intensity weighting coefficient H = Ls1 / (Ls1 + Ls2), where Ls1 is the sunlight illuminance of the driver's side and Ls2 is the sunlight illuminance of the passenger's side.

[0013] In this technical solution, when the sunlight illuminance in the driver's side and the passenger's side are equal, it indicates that the lighting in the driver's and passenger's cabins is uniform. The weighting coefficient H is set to 0.5, meaning that the air conditioning temperature is adjusted the same on both sides, thus improving the temperature balance on both sides of the vehicle and providing a uniform and comfortable experience. When the sunlight illuminance in the driver's side is not equal to that in the passenger's side, i.e., the lighting in the driver's and passenger's cabins is uneven, the weighting coefficient is dynamically adjusted based on the actual light intensity on both sides. This allows the air conditioning system to adjust differently according to the specific lighting conditions on each side, improving passenger comfort. Specifically, the weighting coefficient calculation considers the ratio of light intensity on the driver's side to the passenger's side to differentiate between different light intensities, thereby allowing for differentiated temperature adjustments on both sides and improving the accuracy of temperature regulation.

[0014] Further, the steps for determining the light temperature of the driver's side and the passenger's side based on the sunlight illuminance of the driver's side and the sunlight illuminance of the passenger's side, and the light intensity weighting coefficient, include: calculating the light temperature of the driver's side according to the first formula, which is: (Ls1+Ls2)×H / 60=Ts1; calculating the light temperature of the passenger's side according to the second formula, which is: (Ls1+Ls2)×(1-H) / 60=Ts2; where Ls1 is the sunlight illuminance of the driver's side, Ls2 is the sunlight illuminance of the passenger's side, Ts1 is the light temperature of the driver's side, Ts2 is the light temperature of the passenger's side, and H is the light intensity weighting coefficient.

[0015] In this technical solution, by comprehensively considering the sunlight illuminance of the driver's side and the passenger's side, and combining it with the light intensity weighting coefficient H, the light temperature of the driver's side and the light temperature of the passenger's side are calculated separately. This not only takes into account the overall balance of the temperature inside the vehicle, but also takes into account the different effects of sunlight intensity on the driver's side and the passenger's side, so as to improve the accuracy of temperature regulation on the driver's side and the passenger's side and improve the comfort of the in-vehicle environment.

[0016] Furthermore, the steps for determining the driver's side temperature offset and the passenger's side temperature offset based on the driver's side illumination temperature and the passenger's side illumination temperature respectively include: calculating the driver's side temperature offset value according to the third formula, which is: TAOS1=K s ×Ts1; According to the fourth formula, the passenger seat temperature offset value is calculated. The fourth formula is: TAOS2=K s ×Ts2; where: TAOS1 is the driver's side temperature offset value, TAOS2 is the passenger side temperature offset value, Ts1 is the driver's side illumination temperature, Ts2 is the passenger side illumination temperature, K s This represents the sunlight temperature weighting factor.

[0017] In this technical solution, based on the actual lighting conditions on the driver's side and the passenger's side, a sunlight temperature weighting factor K is introduced. s The system calculates the temperature deviation values ​​for the driver and passenger sides, and compensates for the additional heat from direct sunlight by adjusting the air vent temperatures on both sides. By adjusting the air conditioning vent temperature to compensate for the effects of direct sunlight, the system improves the stability of the vehicle's interior temperature and enhances passenger comfort.

[0018] Furthermore, the steps for determining the solar radiation temperature of the driver's seat and the passenger's seat based on the sunlight illuminance of the driver's seat and the passenger's seat respectively include: calculating the solar radiation temperature according to the fifth formula; the fifth formula is: C=(αI / εσ). 1 / 4 -273.15, where C is the solar radiation temperature. Let I be the absorptivity of an object to solar radiation, and let I be the solar irradiance (W / m²). 2 ε is the emissivity of the windshield, and σ is the Stefan-Boltzmann constant; where I is the illuminance of the driver's side, and the solar radiation temperature C1 of the driver's side is calculated using the fifth formula; I is the illuminance of the passenger side, and the solar radiation temperature C2 of the passenger side is calculated using the fifth formula.

[0019] In this technical solution, the temperature rise caused by solar radiation, i.e., the solar radiation temperature C, is calculated so that the air conditioning system can make appropriate adjustments to this additional heat load, thereby improving the adjustment accuracy of the air conditioning system and passenger comfort.

[0020] Furthermore, the steps for obtaining the first baseline temperature of the driver's seat and the second baseline temperature of the passenger seat include: obtaining the outside temperature, the inside temperature, and the driver's seat and passenger seat set temperatures; calculating the first baseline temperature according to the sixth formula; the sixth formula is: TB1=K set ×T set1 -K r ×T r -K am ×T am The second base temperature is calculated according to the seventh formula; the seventh formula is: TB2 = K set ×T set2 -K r ×T r -K am ×T am ; where TB1 is the primary baseline temperature for the driver's seat, and TB2 is the secondary baseline temperature for the passenger's seat, K set To set the weighting factor for temperature, T set1 Set the temperature for the driver's seat, T set2 Set the temperature for the passenger seat, K r As the weighting factor for the vehicle interior temperature, T r For the temperature inside the car, K am As a weighting factor for the outside temperature, T am The outside temperature of the vehicle.

[0021] This technical solution comprehensively considers multiple factors affecting the air outlet temperature by acquiring the outside temperature, the inside temperature, and the set temperatures of the driver and front passenger. Different weighting factors are assigned to each factor to determine a first base temperature that meets the driver's temperature requirements and a second base temperature that meets the front passenger's requirements. By combining the outside temperature, the inside temperature, and the passengers' personalized temperature settings, the air conditioning outlet temperature can be automatically adjusted according to each passenger's settings and external environmental conditions, significantly improving passenger comfort. By introducing weighting factors and a formulaic calculation method, the air conditioning system achieves intelligent management of the vehicle's interior temperature, improving the accuracy and efficiency of temperature adjustment.

[0022] Further, the steps for determining the driver's seat air outlet temperature and the passenger's seat air outlet temperature based on the first base temperature, the second base temperature, the driver's seat temperature offset value, the passenger's seat temperature offset value, the driver's seat solar radiation temperature, and the passenger's seat solar radiation temperature include: calculating the driver's seat air outlet temperature according to the eighth formula, which is: TAO1 = TB1 - TAOS1 + C1; and calculating the passenger's seat air outlet temperature according to the ninth formula, which is: TAO2 = TB2 - TAOS2 + C2; where TAO1 is the driver's seat air outlet temperature, TAO2 is the passenger's seat air outlet temperature, TB1 is the first base temperature of the driver's seat, TB2 is the second base temperature of the passenger's seat, TAOS1 is the driver's seat temperature offset value, TAOS2 is the passenger's seat temperature offset value, C1 is the driver's seat solar radiation temperature, and C2 is the passenger's seat solar radiation temperature.

[0023] In this technical solution, the air outlet temperatures for the driver and passenger seats are calculated by comprehensively considering the base temperature, temperature deviation value, and solar radiation temperature. Using the control algorithm disclosed herein, the driver and passenger seat air outlet temperatures are specifically determined based on the different solar illuminance on the driver and passenger sides, combined with the individual temperature requirements of the passengers on both sides, and external environmental conditions. This improves the temperature regulation accuracy of the air conditioning system and enhances passenger comfort.

[0024] Furthermore, the air conditioning system includes a driver's side air duct, a passenger side air duct, a driver's side temperature damper, and a passenger side temperature damper. Based on the driver's side air outlet temperature and the passenger side air outlet temperature, the steps for controlling the air conditioning operation include: obtaining the surface temperature of the air conditioner's evaporator and the hot air temperature; determining the first opening degree SW1 of the driver's side temperature damper according to the tenth formula, SW1 = ((TAO1 - T...)). E ) / (T W -T E ())×100%; According to the eleventh formula, determine the second opening degree SW2 of the passenger-side temperature damper; SW2=((TAO2-T E ) / (T W -T E ))×100%; where TAO1 is the driver's air vent temperature, TAO2 is the passenger's air vent temperature, T E T is the surface temperature of the evaporator. W The temperature of the hot air used for heating is set; the opening of the master temperature damper and the passenger temperature damper are adjusted according to the first opening degree SW1 and the second opening degree SW2, respectively.

[0025] In this technical solution, the main exhaust air temperature TAO1 and the evaporator surface temperature T are calculated. E The difference, and the hot air temperature T W With evaporator surface temperature T EBy comparing the differences, the first opening degree SW1 of the driver's side temperature damper was determined. And by calculating the difference between the passenger side air outlet temperature TAO2 and the evaporator surface temperature T... E The difference, and the hot air temperature T W With evaporator surface temperature T E By comparing the differences, the second opening degree SW2 of the passenger-side temperature damper was determined. By determining the opening degrees of the driver's and passenger-side temperature dampers, the control of the opening degree of the temperature damper in each air duct is improved, thereby adjusting the mixing ratio of hot and cold air, improving the accuracy of the outlet air temperature control, and thus improving passenger comfort.

[0026] Furthermore, based on the driver's and passenger's air vent temperatures, the steps for controlling the air conditioning operation include: calculating the combined air vent temperature (TAO) according to formula number 12. X The twelfth formula is: TAO X =TAO1×δ+TAO2×(1-δ), where, TAO X The overall air outlet temperature is defined as follows: TAO1 is the driver's side air outlet temperature, TAO2 is the passenger's side air outlet temperature, and δ is the weighting factor for the driver's cabin temperature. Based on the overall air outlet temperature, TAO... X To control the operation of the air conditioner.

[0027] In this technical solution, by introducing a weighting factor δ, this method can perform a weighted average of the driver's cabin air vent temperature TAO1 and the passenger's cabin air vent temperature TAO2 based on the weighting factor δ, to obtain the comprehensive air vent temperature TAO of the air conditioning system. X Weighted averaging helps to achieve a more balanced temperature on both sides of the vehicle interior, improving the overall passenger experience. Based on the calculated comprehensive air outlet temperature... X Control the operation of the air conditioner to ensure the stability and comfort of the temperature inside the vehicle.

[0028] Furthermore, based on the comprehensive outlet air temperature TAO X The steps for controlling the operation of the air conditioner include: based on the comprehensive air outlet temperature (TAO) X Based on the outside temperature, determine the target airflow mode of the air conditioner; control the opening of the mode damper corresponding to the target airflow mode; wherein, the airflow mode includes one or more of the following modes: face blowing mode, foot blowing mode, defrost mode, face-foot blowing mode, face-defrost mode, foot-defrost mode and face-foot-defrost mode.

[0029] In this technical solution, based on the comprehensive outlet air temperature (TAO) XBased on the outside temperature, the system determines the appropriate airflow mode for the current environmental conditions and controls the opening of the mode damper according to the target airflow mode to enhance passenger comfort in different environments. By providing multiple airflow modes, including face blowing mode, foot blowing mode, defrosting mode, and their combinations, passenger choice is increased, meeting the personalized needs of different passengers. Furthermore, the multiple airflow modes can adapt to different climatic conditions, improving the system's adaptability and flexibility.

[0030] Furthermore, based on the comprehensive outlet air temperature TAO X The steps for controlling the operation of the air conditioner include: setting the combined outlet air temperature (TAO) X If the temperature exceeds the first temperature threshold, control the air conditioner to operate in external circulation mode; at the combined outlet air temperature TAO X When the temperature is less than or equal to the second temperature threshold, the air conditioner is controlled to operate in recirculation mode; wherein the first temperature threshold is greater than the second temperature threshold.

[0031] In this technical solution, the comprehensive outlet air temperature TAO X If the temperature exceeds the first temperature threshold, the air conditioning will switch to external circulation mode, i.e., the vehicle will operate in heating mode. Activating external circulation mode helps prevent window fogging. (TAO is mentioned in the original text, but the context is unclear.) X When the temperature is less than or equal to the second temperature threshold, i.e., the vehicle is in cooling mode, the air conditioning is turned on in recirculation mode to improve cooling efficiency, increase the rate of temperature drop, and reduce energy consumption.

[0032] Furthermore, based on the comprehensive outlet air temperature TAO X The steps for controlling the operation of the air conditioner include: based on the comprehensive air outlet temperature (TAO) X Based on the outside temperature, determine the target temperature and temperature change rate of the evaporator; obtain the surface temperature of the evaporator to obtain the temperature difference between the surface temperature and the target temperature; based on the temperature difference and temperature change rate, use a PI control algorithm to fine-tune the target speed of the compressor; combine the feedforward value of the compressor target speed and the PI control algorithm to determine the target speed of the compressor.

[0033] In this technical solution, based on the comprehensive outlet air temperature (TAO) X By combining the outside temperature with the evaporator temperature, the target temperature and rate of temperature change of the evaporator are determined. Precise control of the evaporator temperature optimizes the cooling effect and improves the dynamic adjustment capability of the air conditioning system. The PI control algorithm can adjust the compressor's target speed in real time based on the temperature difference and rate of temperature change, improving the compressor's rapid response capability and timely adjustment to adapt to temperature changes. By combining feedforward values ​​and the PI control algorithm, the air conditioning system can more accurately control the compressor's target speed, thereby improving the system's energy efficiency ratio and reducing energy consumption.

[0034] Furthermore, the air conditioner includes a first blower installed in the driver's side air duct and a second blower installed in the passenger side air duct. The control method further includes: determining a first speed of the first blower based on the outside temperature and a first base temperature of the driver's side; determining a second speed of the second blower based on the outside temperature and a second base temperature of the passenger side; and controlling the operation of the first blower and the second blower according to the first speed and the second speed, respectively.

[0035] In this technical solution, by controlling the speed of the blowers in the driver's seat and the passenger seat separately, the air volume of the driver's seat air duct and the passenger seat air duct can be controlled independently, thereby improving the accuracy of temperature regulation on the driver's side and the passenger side, which helps to achieve temperature balance on both sides of the vehicle and improve ride comfort.

[0036] In some technical solutions, a vehicle air conditioning control device is provided, comprising: a first acquisition unit for acquiring the sunlight illuminance of the driver's side and the sunlight illuminance of the passenger side; a first determination unit for determining, based on the sunlight illuminance of the driver's side and the sunlight illuminance of the passenger side, a temperature offset value for the driver's side and a temperature offset value for the passenger side, and a solar radiation temperature for the driver's side and a solar radiation temperature for the passenger side; a second acquisition unit for acquiring a first base temperature of the driver's side and a second base temperature of the passenger side; a second determination unit for determining, based on the first base temperature, the second base temperature, the temperature offset value of the driver's side and the temperature offset value of the passenger side, the solar radiation temperature of the driver's side and the solar radiation temperature of the passenger side, and a control unit for controlling the operation of the air conditioning based on the air outlet temperature of the driver's side and the air outlet temperature of the passenger side.

[0037] In some technical solutions, a vehicle air conditioning control device is provided, including a processor and a memory storing program instructions, wherein the processor is configured to execute the vehicle air conditioning control method as described in any of the above technical solutions when running the program instructions.

[0038] In some technical solutions, a vehicle is provided, including: a vehicle body; an air conditioner disposed on the vehicle body; and a control device for the vehicle air conditioner as described in any of the above technical solutions, the control device being installed on the vehicle body for controlling the operation of the air conditioner.

[0039] In some technical solutions, a readable storage medium is provided, which stores program instructions that, when executed, cause a computer to perform the vehicle air conditioning control method as described in any of the above technical solutions.

[0040] The beneficial effects of this invention are:

[0041] The vehicle control method disclosed herein takes into account the different effects of sunlight on the driver and passenger sides, and controls the operation of the air conditioning to adjust the air outlet temperature on the driver's side and the passenger's side, so as to effectively reduce the temperature difference caused by uneven sunlight, thereby improving the overall comfort of passengers in the vehicle.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0058] In some embodiments, combined with Figure 1 As shown, a method for controlling a vehicle air conditioner is provided, including:

[0059] S101, obtain the sunlight illuminance for the driver's side and the passenger's side.

[0060] Optionally, light sensors can be installed on both the driver's side and the passenger side, respectively, to detect the sunlight illuminance on the driver's side and the passenger side. The specific placement of the light sensors is not limited here.

[0061] S102, determine the temperature offset values ​​for the driver's side and the passenger's side based on the sunlight illuminance for the driver's side and the passenger's side, respectively.

[0062] S103, determine the solar radiation temperature of the driver's side and the solar radiation temperature of the passenger side based on the sunlight illuminance of the driver's side and the passenger side respectively.

[0063] S104, obtain the first base temperature of the driver's seat and the second base temperature of the passenger's seat.

[0064] S105, based on the first base temperature, the second base temperature, the driver's seat temperature offset value, the passenger's seat temperature offset value, the driver's seat solar radiation temperature, and the passenger's seat solar radiation temperature, determine the driver's seat air outlet temperature and the passenger's seat air outlet temperature.

[0065] S106 controls the air conditioning operation based on the air vent temperatures of the driver's seat and the passenger's seat.

[0066] The vehicle air conditioning control method disclosed herein determines the impact of sunlight illuminance on the vehicle interior temperature by acquiring the sunlight illuminance for the driver's side and the passenger's side. Specifically, the impact on the temperature of the driver's side is determined by the sunlight illuminance for the driver's side, i.e., the driver's side temperature offset value is determined. Similarly, the impact on the temperature of the passenger's side is determined by the sunlight illuminance for the passenger's side, i.e., the passenger's side temperature offset value is determined. Furthermore, considering the impact of solar radiation on the surface temperature of objects, the solar radiation temperature of the driver's side and the solar radiation temperature of the passenger's side are determined based on the sunlight illuminance for the driver's side and the passenger's side, respectively. Further, based on the basic temperature requirements of the driver and passenger sides—that is, based on the first and second basic temperatures—and combining the driver's side temperature offset value, the passenger's side temperature offset value, the solar radiation temperature of the driver's side, and the solar radiation temperature of the passenger's side, the driver's side air outlet temperature and the passenger's side air outlet temperature are determined separately. The air conditioning operation is controlled so that the air outlet temperature on the driver's side reaches the driver's side air outlet temperature, and the air outlet temperature on the passenger's side reaches the passenger's side air outlet temperature.

[0067] The vehicle control method disclosed herein takes into account the different effects of sunlight illuminance on the driver and passenger sides. It determines the driver's side temperature offset and solar radiation temperature by separately acquiring the sunlight illuminance on the driver's side. Similarly, it acquires the passenger's side sunlight illuminance and determines the passenger's side temperature offset and solar radiation temperature. Based on the baseline temperatures of the driver and passenger sides, it determines the target air outlet temperatures for both sides. This allows for control of the air conditioning system, adjusting the air outlet temperatures on both sides to effectively reduce temperature differences caused by uneven sunlight exposure, thereby improving the overall comfort of passengers inside the vehicle.

[0068] In some embodiments, combined with Figure 2 As shown, a method for controlling a vehicle air conditioner is provided, including:

[0069] S201, obtain the sunlight illuminance for the driver's side and the passenger's side.

[0070] Optionally, light sensors can be installed on both the driver's side and the passenger side, respectively, to detect the sunlight illuminance on the driver's side and the passenger side. The specific placement of the light sensors is not limited here.

[0071] S202, determine the light intensity weighting coefficient based on the sunlight illuminance of the driver's seat and the passenger's seat.

[0072] Optionally, the step of determining the light intensity weighting coefficient based on the sunlight illuminance of the driver's side and the passenger's side includes: when the sunlight illuminance of the driver's side is equal to that of the passenger's side, determining the light intensity weighting coefficient H = 0.5. When the sunlight illuminance of the driver's side is not equal to that of the passenger's side, determining the light intensity weighting coefficient H = Ls1 / (Ls1 + Ls2), where Ls1 is the sunlight illuminance of the driver's side and Ls2 is the sunlight illuminance of the passenger's side.

[0073] In this embodiment, when the sunlight illuminance in the driver's side and the passenger's side are equal, it indicates that the lighting in the driver's and passenger's cabins is uniform. The weighting coefficient H is set to 0.5, meaning the air conditioning temperature is adjusted the same on both sides, thus improving the temperature balance on both sides of the vehicle and providing a uniform and comfortable experience. When the sunlight illuminance in the driver's side is not equal to that in the passenger's side, i.e., the lighting in the driver's and passenger's cabins is uneven, the weighting coefficient is dynamically adjusted based on the actual light intensity on both sides. This allows the air conditioning system to adjust differently according to the specific lighting conditions on each side, improving passenger comfort. Specifically, the weighting coefficient calculation considers the ratio of light intensity on the driver's side to the passenger's side to differentiate between different light intensities, thereby allowing for differentiated temperature adjustments on both sides and improving the accuracy of temperature regulation.

[0074] S203, determine the light temperature of the driver's side and the light temperature of the passenger side based on the sunlight illuminance of the driver's side and the sunlight illuminance of the passenger side, and the light intensity weighting coefficient.

[0075] Optionally, the steps for determining the light temperature of the driver's side and the passenger's side based on the driver's side sunlight illuminance and the passenger's side sunlight illuminance, and the light intensity weighting coefficient, include: calculating the driver's side light temperature according to the first formula: (Ls1 + Ls2) × H / 60 = Ts1. Calculating the passenger's side light temperature according to the second formula: (Ls1 + Ls2) × (1 - H) / 60 = Ts2. Where Ls1 is the driver's side sunlight illuminance, Ls2 is the passenger's side sunlight illuminance, Ts1 is the driver's side light temperature, Ts2 is the passenger's side light temperature, and H is the light intensity weighting coefficient.

[0076] In this embodiment, by taking into account both the sunlight illuminance of the driver's side and the sunlight illuminance of the passenger side, and combining them with the light intensity weighting coefficient H, the light temperature of the driver's side and the light temperature of the passenger side are calculated separately. This not only takes into account the overall balance of the temperature inside the vehicle, but also takes into account the different effects of sunlight intensity on the driver's side and the passenger side, so as to improve the accuracy of temperature regulation on the driver's side and the passenger side and improve the comfort of the in-vehicle environment.

[0077] S204, determine the driver's side temperature offset value and the passenger's side temperature offset value based on the driver's side illumination temperature and the passenger's side illumination temperature, respectively.

[0078] Optionally, the steps of determining the driver's side temperature offset value and the passenger's side temperature offset value based on the driver's side illumination temperature and the passenger's side illumination temperature respectively include: calculating the driver's side temperature offset value according to the third formula, where the third formula is: TAOS1=K s ×Ts1. The passenger-side temperature offset value is calculated according to the fourth formula, which is: TAOS2=K s ×Ts2. Where: TAOS1 is the driver's side temperature offset value, TAOS2 is the passenger side temperature offset value, Ts1 is the driver's side illumination temperature, Ts2 is the passenger side illumination temperature, K s This represents the sunlight temperature weighting factor.

[0079] Optionally, the sunlight temperature weighting factor K s The value of K ranges from 1.5 to 2. s The specific values ​​include, but are not limited to: 1.5, 1.7, 1.9, or 2.

[0080] In this embodiment, based on the actual lighting conditions on the driver's side and the passenger's side, a sunlight temperature weighting factor K is introduced. s The system calculates the temperature deviation values ​​for the driver and passenger sides, and compensates for the additional heat from direct sunlight by adjusting the air vent temperatures on both sides. By adjusting the air conditioning vent temperature to compensate for the effects of direct sunlight, the system improves the stability of the vehicle's interior temperature and enhances passenger comfort.

[0081] Different weights are assigned to the driver's and passenger's sides based on varying lighting conditions to improve the accuracy of temperature regulation and more accurately reflect the impact of light intensity on the interior temperature. Furthermore, the driver's and passenger's light temperatures are determined based on the sunlight intensity and light intensity weighting coefficients for both sides. Then, the driver's and passenger's temperature offset values ​​are determined based on these light temperatures. In this way, by considering the potential differences in lighting conditions on both sides of the vehicle, the temperatures on both sides are compensated separately, allowing the air conditioning vent temperature to adapt to different lighting conditions, thereby improving the temperature balance on both sides of the vehicle and avoiding significant temperature differences.

[0082] S205, the solar radiation temperature of the driver's side and the solar radiation temperature of the passenger side are determined based on the sunlight illuminance of the driver's side and the passenger side, respectively.

[0083] Optionally, the steps for determining the solar radiation temperature of the driver's seat and the passenger's seat based on the sunlight illuminance of the driver's seat and the passenger's seat, respectively, include: calculating the solar radiation temperature according to the fifth formula. The fifth formula is: C=(αI / εσ) 1 / 4 -273.15, in the formula, C is the solar radiation temperature, α is the absorptivity of the object to solar radiation, and I is the solar irradiance (W / m²). 2ε represents the emissivity of the windshield, and σ is the Stefan-Boltzmann constant. Here, I represents the driver's side solar illuminance, and the driver's side solar radiation temperature C1 is calculated using the fifth formula. I represents the passenger's side solar illuminance, and the passenger's side solar radiation temperature C2 is calculated using the fifth formula.

[0084] In this embodiment, the temperature rise due to solar radiation, i.e., the solar radiation temperature C, is calculated so that the air conditioning system can make appropriate adjustments to this additional heat load, thereby improving the adjustment accuracy of the air conditioning system and passenger comfort.

[0085] Optionally, the Stefan-Boltzmann constant σ is taken as 5.67 × 10⁻⁶. -8 W / m 2 ·K 4 。 The absorptivity α of solar radiation ranges from 15% to 30%. The emissivity ε of the windshield is 0.9.

[0086] Optionally, the solar radiation temperature can be calculated based on the sunlight illuminance outside the vehicle. The derivation of the formula for calculating solar radiation temperature is as follows: The effect of solar radiation on the surface temperature of an object is usually calculated under ideal conditions. According to the Stefan-Boltzmann law: P = σAT, where P is the radiant flux (in W), σ is the Stefan-Boltzmann constant, A is the surface area of ​​the object (here referring to the surface area of ​​the windshield of a car), and T is the temperature (Kelvin K).

[0087] If we consider the absorption of solar radiation, based on the principle that the absorbed solar radiation power equals the power radiated outward by the object itself, we can use the formula: αIA = εσAT 4 A simple formula for estimating solar radiation intensity and temperature is derived:

[0088] T=(αI / εσ) 1 / 4 ;

[0089] C = T - 273.15;

[0090] In the formula: I represents solar irradiance, in W / m². 2 α represents the absorptivity of an object to solar radiation. The absorptivity of a car windshield is typically 15% to 30%, and ε represents the emissivity of the windshield, which is approximately 0.9. The above formula can be used to estimate the value of transient solar radiation temperature C under different lighting conditions.

[0091] S206, obtain the first base temperature of the driver's seat and the second base temperature of the passenger's seat.

[0092] Optionally, the steps for obtaining the first baseline temperature for the driver's seat and the second baseline temperature for the passenger seat include: obtaining the outside temperature, the inside temperature, and the driver's seat and passenger seat set temperatures. The first baseline temperature is then calculated using the sixth formula. The sixth formula is: TB1 = K set ×T set1 -K r ×T r -K am ×T am The second base temperature is calculated using the seventh formula. The seventh formula is: TB2 = K set ×T set2 -K r ×T r -K am ×T am Among them, TB1 is the primary baseline temperature for the driver's seat, and TB2 is the secondary baseline temperature for the passenger's seat, in K... set To set the weighting factor for temperature, T set1 Set the temperature for the driver's seat, T set2 Set the temperature for the passenger seat, K r As the weighting factor for the vehicle interior temperature, T r For the temperature inside the car, K am As a weighting factor for the outside temperature, T am The outside temperature of the vehicle.

[0093] In this embodiment, by acquiring the outside temperature, the inside temperature, and the set temperatures of the driver and front passenger, multiple factors affecting the air outlet temperature are comprehensively considered, and weighting factors are set for different factors to determine a first base temperature that meets the driver's temperature requirements and a second base temperature that meets the front passenger's temperature requirements. In this way, by combining the outside temperature, the inside temperature, and the passengers' personalized temperature settings, the air conditioning outlet temperature can be automatically adjusted according to each passenger's settings and external environmental conditions, significantly improving passenger comfort. By introducing weighting factors and a formulaic calculation method, the air conditioning system achieves intelligent management of the inside temperature, improving the accuracy and efficiency of adjustment.

Calculating the passenger's side air outlet temperature according to formula nine, which is: TAO2 = TB2 - TAOS2 + C2. Where TAO1 is the driver's side air outlet temperature, TAO2 is the passenger's side air outlet temperature, TB1 is the first base temperature for the driver's side, TB2 is the second base temperature for the passenger's side, TAOS1 is the driver's side temperature offset value, TAOS2 is the passenger's side temperature offset value, C1 is the driver's side solar radiation temperature, and C2 is the passenger's side solar radiation temperature.

[0098] In this embodiment, considering the impact of sunlight intensity on the vehicle interior temperature, the temperature offset value caused by the increase in interior temperature due to sunlight intensity is subtracted from the base temperature, and then the solar radiation temperature is added to obtain a more accurate air outlet temperature. By comprehensively considering the base temperature, temperature offset value, and solar radiation temperature, the air outlet temperatures for the driver and passenger sides are calculated. Using the control algorithm of this disclosure, based on the different sunlight illuminance on the driver's and passenger's sides, combined with the personalized temperature needs of the passengers on the driver's and passenger's sides, and considering external environmental conditions, the air outlet temperatures for the driver and passenger sides are specifically determined, thereby improving the temperature regulation accuracy of the air conditioning system and enhancing passenger comfort.

[0099] In some embodiments, the air conditioning system includes a driver's side air duct, a passenger side air duct, a driver's side temperature damper, and a passenger side temperature damper, combined with... Figure 3 As shown, a method for controlling a vehicle air conditioner is provided, including:

[0109] S310, adjust the opening of the passenger-side temperature damper according to the second opening degree SW2.

[0110] The tenth formula is: SW1 = ((TAO1 - T) E ) / (T W -T E ))×100%.

[0111] The eleventh formula is: SW2 = ((TAO2-T) E ) / (T W -T E ))×100%.

[0112] In the formula, TAO1 is the driver's side air vent temperature, TAO2 is the passenger's side air vent temperature, and T... E T is the surface temperature of the evaporator. W This refers to the temperature of the hot air used for heating.

[0113] In this embodiment, the temperature damper in the air conditioner controls the mixing ratio of hot and cold air by changing the airflow direction. This is achieved by calculating the main exhaust air temperature TAO1 and the evaporator surface temperature T.

By determining the opening degrees of the driver's and passenger-side temperature dampers, control over the opening degree of each air duct's temperature damper is improved, thereby adjusting the mixing ratio of hot and cold air, enhancing the accuracy of outlet air temperature control, and ultimately improving passenger comfort. Combined with... Figure 9 The diagram shows the adjustment of the temperature damper. Taking the driver's side temperature damper as an example, when the driver's side air outlet temperature TAO1 equals the evaporator surface temperature, SW1=0, representing the entire cold end; when the driver's side air outlet temperature TAO1 equals the hot air temperature T...

[0114] Optionally, the hot air temperature includes the engine coolant temperature, the heater core temperature, or the maximum of the coolant temperature and the heater core temperature.

[0115] Optionally, the air conditioner includes an evaporator for cooling and a heater core for heating. When temperature adjustment is required, the temperature damper adjusts its position to mix the cold air passing through the evaporator and the hot air passing through the heater core in different proportions before blowing it out. For example, when the user sets the temperature below a low-temperature threshold, the temperature damper adjusts its opening to direct most of the air to the evaporator, allowing the cold air to be blown out directly, with only a small amount or no air passing through the heater core, thus achieving a cooling effect. The low-temperature threshold ranges from 16°C to 18°C. When the user sets the temperature above a high-temperature threshold, the temperature damper adjusts its opening to allow more air to pass through the heater core, either heating the air before blowing it out, or mixing the cold and hot air to reach a suitable temperature before blowing it out. The high-temperature threshold ranges from 28°C to 30°C. Based on different outlet air temperature requirements, it participates in controlling the mixing ratio of cold and warm air to achieve adaptive adjustment of the passenger cabin temperature.

[0116] Optionally, the step of adjusting the opening of the master driver's temperature damper according to the first opening SW1 includes: determining the drive duty cycle of the motor corresponding to the master driver's temperature damper according to the first opening SW1; and controlling the motor to run according to the drive duty cycle.

[0118] Optionally, a feedforward + PI control algorithm is used for feedback control of the motor of the temperature damper to improve the control accuracy of the temperature damper. Taking the driver's side temperature damper control as an example, the specific control method includes: according to TAO... 1，The feedforward value of the driver's side temperature damper motor is obtained by looking up a table separately. At the same time, the difference between the actual air outlet temperature detected by the temperature sensor on the driver's side and TAO1 is obtained and used for PI control as a fine adjustment of the temperature damper motor. The Kp and Ki values ​​in the PI control are calculated by looking up a table based on the difference between the actual air outlet temperature and TAO1.

In the formula, TAO X δ represents the overall air outlet temperature of the air conditioner, TAO1 is the air outlet temperature of the driver's side, TAO2 is the air outlet temperature of the passenger side, and δ is the weighting factor for the temperature of the driver's cabin.

[0127] S407, based on the comprehensive outlet air temperature TAO X To control the operation of the air conditioner.

[0128] In this embodiment, by introducing a weighting factor δ, this method can perform a weighted average of the driver's side air vent temperature TAO1 and the passenger side air vent temperature TAO2 based on the weighting factor δ of the driver's cabin temperature, to obtain the comprehensive air vent temperature TAO. X Weighted averaging helps to achieve a more balanced temperature on both sides of the vehicle interior, improving the overall passenger experience. Based on the calculated comprehensive air outlet temperature... X Control the operation of the air conditioner to ensure the stability and comfort of the temperature inside the vehicle.

[0129] Optionally, a weighting factor for the driver's cabin temperature can be determined based on the volumes of the driver's cabin and the passenger cabin. When the volumes of the driver's cabin and the passenger cabin are equal, δ = 0.5. When the volumes of the driver's cabin and the passenger cabin are not equal, the weighting factor is calculated using the following formula: δ = V1 / (V1 + V2), where V1 is the volume of the driver's cabin and V2 is the volume of the passenger cabin. The volumes of the driver's cabin and the passenger cabin can be estimated based on the vehicle's body design parameters, which will not be detailed here. This allows for a reasonable determination of the proportion of airflow temperature emanating from each cabin, thereby improving the accuracy of the overall airflow temperature calculation and enhancing the precision of the air conditioning control.

[0130] In some embodiments, combined with Figure 5 As shown, a method for controlling a vehicle air conditioner is provided, including:

[0140] The air supply mode includes one or more of the following modes: face blowing mode, foot blowing mode, defrost mode, face-foot blowing mode, face-defrost mode, foot-defrost mode, and face-foot blowing-defrost mode.

[0141] In this embodiment, based on the comprehensive outlet air temperature (TAO) X Based on the outside temperature, the system determines the appropriate airflow mode for the current environmental conditions and controls the opening of the mode damper according to the target airflow mode to enhance passenger comfort in different environments. By providing multiple airflow modes, including face blowing mode, foot blowing mode, defrosting mode, and their combinations, passenger choice is increased, meeting the personalized needs of different passengers. Furthermore, the multiple airflow modes can adapt to different climatic conditions, improving the system's adaptability and flexibility.

[0142] Optionally, the steps for controlling the opening of the mode damper corresponding to the target air supply mode include: determining the installation position of the mode damper corresponding to the target air supply mode; determining the opening angle of the mode damper based on the installation position; and controlling the motor of the mode damper to operate based on the opening angle to drive the mode damper to open. The air duct settings for different air supply modes of an air conditioner are different. For example, the air duct settings for the face-blowing mode and the foot-blowing mode are different. The air duct for the face-blowing mode is set towards the passenger's face, while the air duct for the foot-blowing mode is set towards the passenger's feet. Obviously, the air duct settings for the two are different, resulting in different installation positions for their corresponding mode dampers. Therefore, determining the opening angle of the mode damper based on its installation position enables precise control of the mode damper.

[0155] In this embodiment, at the combined outlet air temperature TAO X If the temperature exceeds the first temperature threshold t1, the air conditioning will operate in external circulation mode, i.e., the vehicle will operate in heating mode. Activating external circulation mode helps prevent window fogging. (TAO is the optimal temperature setting.) X When the temperature is less than or equal to the second temperature threshold t2, i.e., the vehicle is operating in cooling mode, the air conditioning is switched to recirculation mode to improve cooling efficiency, increase the rate of temperature drop, and reduce energy consumption. Combined with... Figure 11 As shown, the combined outlet air temperature TAO X A graph showing the relationship between the damper opening and the mode damper.

[0156] Optionally, the first temperature threshold t1 ranges from 26°C to 30°C, specifically including but not limited to 26°C, 27°C, 28°C, 29°C, or 30°C. The second temperature threshold t2 ranges from 15°C to 18°C, specifically including but not limited to 15°C, 16°C, 17°C, or 18°C.

Based on the difference between the actual surface temperature of the evaporator and the target surface temperature, a PI algorithm is used to fine-tune the compressor's target speed. Using the feedforward value, the target base speed of the compressor is obtained from a lookup table, and combined with the PI algorithm control, the final target speed of the compressor is determined.
