TECHNICAL FIELD

[0002] The present application relates to the technical field of motor vehicles, and in particular to a vehicle temperature processing method, device, equipment, storage medium and program product. BACKGROUND

[0003] With the continuous evolution and upgrading of motor vehicle technology, users' expectations for vehicle comfort are also constantly improving. Therefore, as a key element to improve the driving experience, in-vehicle temperature control has become an area that vehicle design teams need to focus on and strive for perfection.

[0004] Currently, in the related art, the collection of in-vehicle temperature usually needs to set an independent temperature sensor.

[0005] However, the inventors have found that the related art at least has the following technical problems: setting the temperature sensor in the vehicle increases the manufacturing cost of the vehicle, and the temperature sensor in the vehicle has the problem of inaccurate internal temperature acquisition when the vehicle is hot started. SUMMARY

[0006] The present application provides a vehicle temperature processing method, device, equipment, storage medium and program product to solve the problem of increased vehicle manufacturing cost caused by setting a temperature sensor in the vehicle.

[0007] In a first aspect, the present application provides a vehicle temperature processing method, comprising: in response to the vehicle being powered on, obtaining an external temperature, a parked in-vehicle temperature recorded when the vehicle is powered off, a power-off time and a power-on time; obtaining a hibernation duration by subtracting the power-off time from the power-on time; if the external temperature is greater than or equal to a preset external temperature threshold and the hibernation duration is less than a first duration threshold, determining an in-vehicle temperature according to the hibernation duration, the external temperature and the parked in-vehicle temperature.

[0008] Further, by recording the outside temperature when the vehicle is powered on, the parking indoor temperature when the vehicle is powered off, the power-off time and the power-on time, in the case that the outside temperature is greater than or equal to a preset outside temperature threshold and the sleep duration is less than a first duration threshold, the sleep duration, the outside temperature and the parking indoor temperature are used to calculate the indoor temperature, without setting a temperature sensor in the vehicle, the vehicle manufacturing cost is reduced, and the accuracy of the indoor temperature calculation is ensured by different processing for different situations, thereby avoiding the problem that the indoor temperature acquisition value cannot accurately represent the indoor temperature when the vehicle is started.

[0009] In a possible implementation, the indoor temperature is determined according to the sleep duration, the outside temperature and the parking indoor temperature, including: subtracting the parking indoor temperature from the outside temperature to obtain a first temperature difference; according to the first temperature difference, searching for a preset first temperature difference and coefficient correspondence relationship to obtain a first indoor temperature correction coefficient; inputting the parking indoor temperature, the first indoor temperature correction coefficient and the sleep duration into a preset first indoor temperature calculation formula to obtain the indoor temperature.

[0010] Further, in the case of short-time parking, by calculating the temperature difference between the outside temperature and the parking indoor temperature, a corresponding correction coefficient is obtained, the parking indoor temperature is corrected by using the correction coefficient and the sleep duration to obtain the indoor temperature, without adding a temperature sensor in the vehicle, thereby reducing the vehicle manufacturing cost.

[0011] In a possible implementation, if the outside temperature is greater than or equal to the outside temperature threshold and the sleep duration is greater than or equal to the first duration threshold, the upper air duct temperature and the lower air duct temperature are obtained, and the air duct temperature difference between the upper air duct temperature and the lower air duct temperature is calculated; if the air duct temperature difference is less than a preset temperature difference threshold, the upper air duct temperature is determined as the indoor temperature; if the air duct temperature difference is greater than or equal to the preset temperature difference threshold, the indoor temperature is determined according to the sleep duration, the upper air duct temperature and the lower air duct temperature.

[0012] Further, in the case that the sleep duration is greater than or equal to the first duration threshold and less than a second duration threshold, the average value of the upper air duct temperature and the lower air duct temperature is directly used to calculate the indoor temperature, the indoor sensor is not added, and the vehicle manufacturing cost is reduced.

[0013] In a possible implementation, the indoor temperature is determined according to the sleep duration, the upper air duct temperature and the lower air duct temperature, including: if the sleep duration is greater than or equal to the first duration threshold and less than the second duration threshold, the average value of the upper air duct temperature and the lower air duct temperature is calculated to obtain an average temperature; the average temperature is determined as the indoor temperature.

[0014] In one possible implementation, if the sleep duration is greater than or equal to the second duration threshold and less than the third duration threshold, the temperature coefficient is calculated based on the sleep duration; the maximum value of the upwind duct temperature and the maximum value of the downwind duct temperature are determined; the temperature coefficient, the maximum value of the upwind duct temperature and the maximum value of the downwind duct temperature are input into the second internal temperature calculation formula to obtain the vehicle interior temperature; if the sleep duration is greater than or equal to the third duration threshold, the downwind duct temperature is determined as the vehicle interior temperature.

[0015] In a possible implementation, the second internal temperature calculation formula is as follows: incar =T max1 (1-h)+T max2 ·h

[0016] Where, T incar Indicates the temperature inside the car, T max1 Indicates the maximum temperature of the upper duct, T max2 It represents the maximum value of downwind duct temperature, and h represents temperature coefficient.

[0017] Furthermore, by using different formulas to calculate the temperature inside the vehicle using the upwind duct temperature and the downwind duct temperature according to the length of the sleep time, the temperature inside the vehicle can be obtained without using a temperature sensor inside the vehicle, thereby reducing the manufacturing cost of the temperature inside the vehicle.

[0018] In one possible implementation, after obtaining the sleep duration by subtracting the power-off time from the power-on time, it also includes: if the outside temperature is less than the outside temperature threshold and the sleep duration is less than the fourth duration threshold, then the inside temperature of the vehicle is determined based on the sleep duration, the outside temperature and the inside temperature of the parked vehicle.

[0019] Furthermore, by calculating the interior temperature of the vehicle when the outside temperature is low and the sleep time is greater than the fourth time threshold, the interior temperature can be obtained without setting an interior temperature sensor, thereby reducing vehicle manufacturing costs.

[0020] In a possible implementation, after the power-on time is subtracted by the power-off time to obtain the hibernation duration, the method further includes: if the outdoor temperature is less than the outdoor temperature threshold, and the hibernation duration is greater than or equal to a fourth duration threshold and less than a fifth duration threshold, calculating a second temperature difference between the outdoor temperature and the indoor temperature when the vehicle is parked; obtaining a second indoor temperature correction coefficient according to the second temperature difference by searching a preset second temperature difference and coefficient correspondence relationship; calculating an indoor temperature basic value according to the second indoor temperature correction coefficient and the indoor temperature when the vehicle is parked; calculating a third temperature difference between the outdoor temperature and the indoor temperature basic value; obtaining a third indoor temperature correction coefficient according to the third temperature difference by searching a preset third temperature difference and coefficient correspondence relationship; inputting the indoor temperature basic value, the third indoor temperature correction coefficient and the hibernation duration into a third indoor temperature calculation formula to obtain the indoor temperature; if the outdoor temperature is less than the outdoor temperature threshold, and the hibernation duration is greater than or equal to the fifth duration threshold, obtaining an upper air duct temperature and a lower air duct temperature; and determining the indoor temperature according to the upper air duct temperature and the lower air duct temperature.

[0021] In a possible implementation, the third indoor temperature calculation formula is as follows: T incar = T incar_60 + K3 (t-a)

[0022] In the formula, T incar represents the indoor temperature, T incar_60 represents the indoor temperature basic value, K3 represents the third indoor temperature correction coefficient, t represents the hibernation duration, and a represents a constant equal to the fourth duration threshold.

[0023] Further, by using different calculation methods to calculate the indoor temperature according to the time range in which the hibernation duration is located when the outdoor temperature is less than the outdoor temperature threshold, the indoor temperature can be obtained without setting a sensor in the vehicle, the accuracy of the indoor temperature is ensured, and the manufacturing cost of the vehicle is reduced.

[0024] In a possible implementation, after the indoor temperature is obtained, the method further includes: in response to the power-on being completed, obtaining an air conditioner outlet temperature and a sunlight intensity; determining the indoor temperature as a front seat head temperature, an interior material temperature and a sunlight material temperature; determining the outdoor temperature as an exterior material temperature; determining a new front seat head temperature according to the front seat head temperature, the air conditioner outlet temperature, the exterior material temperature and the sunlight material temperature; determining a new interior material temperature according to the interior material temperature and the front seat head temperature; determining a new sunlight material temperature according to the sunlight material temperature, the front seat head temperature and the sunlight intensity; and determining a new indoor temperature according to the new front seat head temperature, the new interior material temperature and the new sunlight material temperature.

[0025] Further, the vehicle interior temperature after power-on is calculated by combining the air conditioner outlet temperature, the sunlight intensity, the front row head temperature, the interior material temperature, the exterior material temperature and the sunlight material temperature, so that the vehicle interior temperature can be obtained without setting a vehicle interior temperature sensor, and the manufacturing cost of the vehicle is reduced.

[0026] In a possible implementation, after the new vehicle interior temperature is determined, the method further includes: determining a new exterior material temperature according to the exterior material temperature, the front row head temperature and the vehicle exterior temperature; and re-executing the steps of determining the new front row head temperature to determining the new vehicle interior temperature by using the air conditioner outlet temperature, the sunlight intensity, the new front row head temperature, the new interior material temperature, the new sunlight material temperature and the new exterior material temperature.

[0027] Further, the exterior material temperature is updated by using the exterior material temperature, the front row head temperature and the vehicle exterior temperature, so that the new exterior material temperature is used to update the front row head temperature in the subsequent process, and the vehicle interior temperature is continuously updated, the vehicle interior temperature can be continuously updated after power-on without the vehicle interior temperature sensor, and the manufacturing cost of the vehicle is reduced.

[0028] In a second aspect, the present application provides a vehicle temperature processing apparatus, including: a data acquisition module, configured to acquire a vehicle exterior temperature, a parking vehicle interior temperature recorded when power-off, a power-off time and a power-on time in response to power-on of the vehicle; a time length calculation module, configured to obtain a hibernation time length by subtracting the power-off time from the power-on time; and a first determination module, configured to determine a vehicle interior temperature according to the hibernation time length, the vehicle exterior temperature and the parking vehicle interior temperature if the vehicle exterior temperature is greater than or equal to a vehicle exterior temperature threshold and the hibernation time length is less than a first time length threshold.

[0040] Currently, the related art usually needs to install an independent temperature sensor to collect the temperature in the vehicle. This will increase the manufacturing cost of the vehicle.

[0041] In order to solve the above technical problems, the inventors propose the following technical concept: the temperature in the vehicle is calculated by combining the power-off time, power-on time, temperature in the vehicle, and temperature outside the vehicle.

[0046] The processing unit 101 is configured to acquire data measured by the sensor 102 and the power-off and power-on time of the vehicle, and determine the temperature in the vehicle by using the data.

[0047] In a possible implementation, the embodiment of the present application is applied to a case where the air conditioner is used before the vehicle is powered off.

[0048] It can be understood that the structure shown in the embodiment of the present application does not constitute a specific limitation on the vehicle temperature processing method. In other possible embodiments of the present application, the above architecture can include more or fewer components than those shown, or combine certain components, or split certain components, or different component arrangements, which can be determined according to actual application scenarios, and are not limited herein. The components shown in Fig. 1 can be realized by hardware, software, or a combination of software and hardware.

[0049] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0050] FIG. 2 is a flowchart of a vehicle temperature processing method according to an embodiment of the present application. The execution subject of the embodiment of the present application can be the processing unit 101 in FIG. 1. As shown in FIG. 2, the method comprises the following steps.

[0051] S201: In response to the vehicle being powered on, obtaining an outdoor temperature, a parked-in-vehicle temperature recorded when the vehicle is powered off, a power-off time and a power-on time.

[0052] In this step, the vehicle being powered on can include the automobile being powered on, can include the vehicle key being rotated to the power-on position, or the start button being pressed. The outdoor temperature can be measured by the temperature sensor installed on the vehicle, the parked-in-vehicle temperature can be the in-vehicle temperature calculated before the power-off, the power-off time can be obtained by obtaining the time stamp when the power-off, and the power-on time can be obtained by obtaining the time stamp when the vehicle is powered on.

[0053] S202: Obtaining the hibernation duration by subtracting the power-off time from the power-on time.

[0054] In this step, for example, the power-on time is 3:30, the power-off time is 2:30, and the hibernation duration is 1 hour; for another example, the power-on time is 15:20, the power-off time is 15:10, and the hibernation duration is 10 minutes; for another example, the power-on time is 18:35, the power-off time is 16:10, and the hibernation duration is 2 hours and 25 minutes.

[0055] S203: If the outdoor temperature is greater than or equal to a preset or equal outdoor temperature threshold value, and the hibernation duration is less than a first duration threshold value, determining the in-vehicle temperature according to the hibernation duration, the outdoor temperature and the parked-in-vehicle temperature.

[0056] In this step, the outdoor temperature threshold value is, for example, 13℃, 15℃ or 16℃. The first duration threshold value is, for example, 9 minutes, 10 minutes or 12 minutes. Determining the in-vehicle temperature according to the hibernation duration, the outdoor temperature and the parked-in-vehicle temperature can include inputting the hibernation duration, the outdoor temperature and the parked-in-vehicle temperature into a first in-vehicle temperature calculation neural network model pre-trained to obtain the in-vehicle temperature output by the model.

[0057] In this step, the first duration threshold value and the outdoor temperature threshold value can be pre-set by the staff according to experimental data or experience parameters.

[0058] From the description of the above embodiments, in the case that the outdoor temperature is greater than or equal to the preset outdoor temperature threshold, and the hibernation duration is less than the first duration threshold, the hibernation duration, the outdoor temperature and the parked-in-car temperature are used to calculate the in-car temperature, without the need to set a temperature sensor in the car, thereby reducing the manufacturing cost of the vehicle, and at the same time, since different situations are handled differently, the accuracy of the in-car temperature calculation is ensured, and the problem that the in-car temperature acquisition value cannot accurately represent the in-car temperature when the vehicle is started is avoided.

[0059] In the above embodiments, in the case that the air duct temperature difference is less than the preset temperature difference threshold, it is indicated that the sunlight radiation during hibernation is not strong, and the upwind air duct temperature can be directly determined as the in-car temperature; in the case that the air duct temperature difference is greater than or equal to the preset temperature difference threshold, it is indicated that the sunlight radiation during hibernation is strong, and the upwind air duct temperature is biased high due to the sun, and cannot represent the real in-car temperature, and the average value of the upwind air duct temperature and the downwind air duct temperature is assigned to the in-car temperature, thereby increasing the accuracy of the in-car temperature determination.

[0060] In a possible implementation, in the step S203, the in-car temperature is determined according to the hibernation duration, the outdoor temperature and the parked-in-car temperature, including:

[0061] S2031: The outdoor temperature is subtracted from the parked-in-car temperature to obtain a first temperature difference.

[0062] In this step, for example, the outdoor temperature is 25℃, and the parked-in-car temperature is 20℃, then the first temperature difference is 5℃. For another example, the outdoor temperature is 30℃, and the parked-in-car temperature is 18℃, then the first temperature difference is 12℃.

[0063] S2032: According to the first temperature difference, a preset first temperature difference and coefficient correspondence relationship is searched to obtain a first in-temperature correction coefficient.

[0064] In this step, the first temperature difference and coefficient correspondence relationship can be preset by the staff according to experimental data or empirical parameters, and can be stored in the form of a table, a key-value pair, etc.

[0065] For example, the first temperature difference and coefficient correspondence relationship is shown in Table 1.

[0066] Table 1: Exemplary table of first temperature difference and coefficient correspondence relationship

[0067] S2033: The parked-in-car temperature, the first in-temperature correction coefficient and the hibernation duration are input into a preset first in-temperature calculation formula to obtain the in-car temperature.

[0068] In this step, the first in-temperature calculation formula is as follows: T incar= T incarMem + k · t

[0069] In the formula, T incar represents the temperature in the vehicle, T incarMem represents the temperature in the vehicle when parking, k represents a first internal temperature correction coefficient, and t represents the hibernation duration.

[0070] As can be seen from the description of the above embodiments, in the case of short-time parking, the temperature difference between the outdoor temperature and the temperature in the vehicle when parking is calculated to obtain a corresponding correction coefficient. The temperature in the vehicle when parking is corrected by using the correction coefficient and the hibernation duration to obtain the temperature in the vehicle. No temperature sensor is added in the vehicle, thereby reducing the manufacturing cost of the vehicle.

[0071] In a possible implementation, the unit of the first internal temperature correction coefficient can be degrees Celsius per minute. For example, the outdoor temperature is 30°C, the hibernation duration is 5 minutes, the temperature in the vehicle when parking is 20°C, the first temperature difference is 10°C, the first temperature difference is searched for the corresponding relationship with the coefficient to obtain the first internal temperature correction coefficient of 0.5, and the temperature in the vehicle T incar = 20 + 0.5 x 5 = 22.5°C.

[0072] In a possible implementation, after the hibernation duration is obtained by subtracting the power-off time from the power-on time in the above step S202, the method further includes the following steps.

[0073] S204: If the outdoor temperature is greater than the outdoor temperature threshold and the hibernation duration is greater than or equal to the first duration threshold, the temperature in the upper air duct and the temperature in the lower air duct are obtained, and the air duct temperature difference between the temperature in the upper air duct and the temperature in the lower air duct is calculated. If the air duct temperature difference is less than a preset temperature difference threshold, the temperature in the upper air duct is determined as the temperature in the vehicle. If the air duct temperature difference is greater than or equal to the preset temperature difference threshold, the temperature in the vehicle is determined according to the hibernation duration, the temperature in the upper air duct, and the temperature in the lower air duct.

[0074] In this step, the temperature in the upper air duct can include at least one of the temperature in the left front blowing air duct, the temperature in the right front blowing air duct, the temperature in the left rear blowing air duct, and the temperature in the right rear blowing air duct. The temperature in the lower air duct can include at least one of the temperature in the left foot blowing air duct, the temperature in the right front foot blowing air duct, the temperature in the left rear foot blowing air duct, and the temperature in the right rear foot blowing air duct. The calculation method of the air duct temperature difference can include subtracting the maximum value of the temperature in the lower air duct from the maximum value of the temperature in the upper air duct to obtain the air duct temperature difference. Determining the temperature in the upper air duct as the temperature in the vehicle can include determining the maximum value of the temperature in the upper air duct as the temperature in the vehicle, or determining the average value of the temperature in the upper air duct as the temperature in the upper air duct. Determining the temperature in the vehicle according to the hibernation duration, the temperature in the upper air duct, and the temperature in the lower air duct can include inputting the hibernation duration, the temperature in the upper air duct, and the temperature in the lower air duct into a second vehicle temperature calculation neural network model to obtain the temperature in the vehicle output by the model.

[0075] The preset temperature difference threshold value is, for example, 4℃, 5℃, 6℃, or the like, and can be preset by a worker according to experimental data or an experience parameter.

[0076] As can be known from the description of the above embodiments, in the case that the outside temperature is greater than or equal to the outside temperature threshold value and the hibernation duration is greater than or equal to the first duration threshold value, the vehicle interior temperature is calculated in different ways according to the air duct temperature difference between the upper air duct temperature and the lower air duct temperature, without the need to set an independent sensor in the vehicle interior, thereby reducing the vehicle manufacturing cost, and at the same time, the accuracy of calculating the vehicle interior temperature is increased due to different processing of different cases.

[0077] In a possible implementation, in the step S204, the vehicle interior temperature is determined according to the hibernation duration, the upper air duct temperature, and the lower air duct temperature, including:

[0078] S2041: If the hibernation duration is greater than or equal to the first duration threshold value and less than the second duration threshold value, the average value of the upper air duct temperature and the lower air duct temperature is calculated to obtain an average temperature, and the average temperature is determined as the vehicle interior temperature.

[0079] In this step, in the case that the upper air duct temperature or the lower air duct temperature includes multiple temperature values, the average value of the upper air duct temperature and the lower air duct temperature can include the average value of the maximum value of the upper air duct temperature and the maximum value of the lower air duct temperature, to obtain the average temperature.

[0080] The second duration threshold value is, for example, 58 minutes, 60 minutes, 65 minutes, or the like.

[0081] As can be known from the description of the above embodiments, in the case that the hibernation duration is greater than or equal to the first duration threshold value and less than the second duration threshold value, the average value of the upper air duct temperature and the lower air duct temperature is directly used to calculate the vehicle interior temperature, to realize the calculation of the vehicle interior temperature in the case that the hibernation duration is within a certain range, without the need to add a vehicle interior sensor, thereby reducing the vehicle manufacturing cost.

[0082] In a possible implementation, in the step S204, the vehicle interior temperature is determined according to the hibernation duration, the upper air duct temperature, and the lower air duct temperature, including:

[0083] S2042: If the hibernation duration is greater than or equal to the second duration threshold value and less than the third duration threshold value, a temperature coefficient is calculated according to the hibernation duration, the maximum value of the upper air duct temperature is determined, and the maximum value of the lower air duct temperature is determined. The temperature coefficient, the maximum value of the upper air duct temperature, and the maximum value of the lower air duct temperature are input into a second interior temperature calculation formula to obtain the vehicle interior temperature.

[0084] In this step, the temperature coefficient is calculated according to the sleep duration, including inputting the sleep duration into the coefficient calculation formula to obtain the temperature coefficient.

[0085] wherein the third duration threshold is, for example, 1 hour 50 minutes, 1 hour 58 minutes, 2 hours, 2 hours 10 minutes, etc. The coefficient calculation formula is as follows: h = b + b(t - 1)

[0086] wherein t represents the sleep duration, h represents the temperature coefficient, and b is a preset constant. The b can be calibrated by a worker according to experimental data or experience parameters. The b can be, for example, 0.5, 0.45, 0.52, etc.

[0087] In a possible implementation, the second inner temperature calculation formula is as follows: T incar = T max1 (1 - h) + T max2 · h

[0088] wherein T incar represents the inner temperature of the vehicle, T max1 represents the maximum value of the upper air duct temperature, T max2 represents the maximum value of the lower air duct temperature, and h represents the temperature coefficient.

[0089] For example, b is 0.5, the sleep duration is 90 minutes, i.e. t = 1.5, and h = 0.75, so that T incar = T max1 (1 - 0.75) + T max2 · 0.75 = 0.25T max1 + 0.75T max2 .

[0090] S2043: If the sleep duration is greater than or equal to the third duration threshold, the lower air duct temperature is determined as the inner temperature of the vehicle.

[0091] In this step, the third duration threshold is, for example, 1 hour 58 minutes, 2 hours, 2 hours 10 minutes, etc. If there are multiple values of the lower air duct temperature, the maximum lower air duct temperature can be selected.

[0092] As can be seen from the description of the above embodiments, the embodiments of the present application can calculate the inner temperature of the vehicle by using different formulas of the upper air duct temperature and the lower air duct temperature according to the size of the sleep duration, so that the inner temperature of the vehicle can be obtained without using the temperature sensor in the vehicle, and the manufacturing cost of the inner temperature of the vehicle is reduced.

[0093] In a possible implementation, after the sleep duration is obtained by subtracting the power-off time from the power-on time in the above step S202, the method further includes:

[0094] S210: If the outside temperature is less than the outside temperature threshold value and the hibernation duration is less than the fourth duration threshold value, the inside temperature is determined according to the hibernation duration, the outside temperature and the parking inside temperature.

[0095] In this step, the fourth duration threshold value is, for example, 58 minutes, 60 minutes, 61 minutes, etc. The process of determining the inside temperature according to the hibernation duration, the outside temperature and the parking inside temperature is similar to the above step S203, which will not be described here.

[0096] From the description of the above embodiments, it can be known that the embodiments of the present application calculate the inside temperature in the case that the outside temperature is small and the hibernation duration is greater than the fourth duration threshold value. The inside temperature can be obtained without setting an inside temperature sensor, thereby reducing the vehicle manufacturing cost.

[0097] In a possible implementation, after the hibernation duration is obtained by subtracting the power-off time from the power-on time in the above step S202, the method further includes:

[0098] S211: If the outside temperature is less than the outside temperature threshold value and the hibernation duration is greater than or equal to the fourth duration threshold value and less than the fifth duration threshold value, a second temperature difference between the outside temperature and the parking inside temperature is calculated. A second inside temperature correction coefficient is obtained by searching a preset second temperature difference and coefficient correspondence according to the second temperature difference. An inside temperature basic value is calculated according to the second inside temperature correction coefficient and the parking inside temperature. A third temperature difference between the outside temperature and the inside temperature basic value is calculated. A third inside temperature correction coefficient is obtained by searching a preset third temperature difference and coefficient correspondence according to the third temperature difference. The inside temperature is obtained by inputting the inside temperature basic value, the third inside temperature correction coefficient and the hibernation duration into a third inside temperature calculation formula.

[0099] In this step, the second temperature difference between the outside temperature and the parking inside temperature can be calculated by subtracting the parking inside temperature from the outside temperature to obtain the second temperature difference. The second temperature difference and coefficient correspondence and the third temperature difference and coefficient correspondence can be the same as or similar to the above first temperature difference and coefficient correspondence, which will not be described here. The third temperature difference between the outside temperature and the inside temperature basic value can be calculated by subtracting the inside temperature basic value from the outside temperature to obtain the third temperature difference.

[0100] The fifth duration threshold value is, for example, 3 hours 50 minutes, 4 hours, 4 hours 10 minutes, etc., which can be set by a worker according to experimental data or experience parameters in advance.

[0101] In a possible implementation, the third inside temperature calculation formula is as follows: incar T incar_60 = T incar + K3 (t-a)

[0102] In the formula, T incar_60represents the internal temperature base value, K3 represents the third internal temperature correction coefficient, t represents the sleep duration, and a represents a constant equal to the fourth duration threshold.

[0103] For example, the fourth time threshold is 1 hour, the outside temperature is 0°C, and the temperature inside the parked car is T incarMem is 20℃, through the difference of -20℃, the second internal temperature correction coefficient K2 is -0.12, then after 60 minutes of sleep, the internal temperature base value T incar_60 =20+K2*60=20-7.2=12.8℃; through the outside temperature and T incar_60 The difference is 0-12.8 = -12.8 ° C, and the third internal temperature correction coefficient K3 is about -0.075. Then after 120 minutes of sleep, T incar =T incar_60 +K3*(120-60)=12.8-0.075*60=8.3℃, that is, after 2 hours of sleep, the temperature inside the car drops from 20℃ to 8.3℃.

[0104] S212: If the outside temperature is less than the outside temperature threshold and the sleep duration is greater than or equal to the fifth duration threshold, obtain the upwind duct temperature and the downwind duct temperature, and determine the inside temperature of the vehicle based on the upwind duct temperature and the downwind duct temperature.

[0105] In this step, the upwind duct temperature and the downwind duct temperature may both include at least one temperature value. Determining the interior temperature of the vehicle based on the upwind duct temperature and the downwind duct temperature may include calculating the average of the minimum value of the upwind duct temperature and the minimum value of the downwind duct temperature to obtain the interior temperature of the vehicle.

[0106] Among them, the fifth time threshold can be pre-set by the staff based on experimental data or experience parameters, such as 3 hours and 50 minutes, 4 hours, 4 hours and 10 minutes, etc.

[0107] From the description of the above embodiments, it can be seen that the embodiments of the present application use different calculation methods to calculate the temperature inside the vehicle according to the time range of the sleep time when the temperature outside the vehicle is lower than the temperature outside the vehicle threshold. While ensuring the accuracy of the temperature inside the vehicle, there is no need to set up a sensor inside the vehicle to obtain the temperature inside the vehicle, thereby reducing the manufacturing cost of the vehicle.

[0108] In one possible implementation, the second and third internal temperature correction coefficients are used to represent the internal temperature change rate in different time periods because the internal temperature decreases at different rates in different time periods. Therefore, to obtain more accurate internal temperature estimates, it is necessary to estimate the internal temperature values ​​in sections. Furthermore, the calibration values ​​in Table 1 above represent actual cooling / heating rates under different interior / exterior temperature differences, as obtained through actual vehicle testing.

[0109] In a possible implementation, if the processing unit (or air conditioner controller) is first flashed with software, since the stored indoor temperature is null, the indoor temperature needs to be assigned a value when power is turned on, and the outdoor temperature can be assigned to the indoor temperature.

[0110] In a possible implementation, after obtaining the indoor temperature in any of the above embodiments, the method further includes:

[0111] S220: obtaining the air conditioner outlet temperature and the sunlight intensity in response to completion of power-on.

[0112] In this step, completion of power-on can include successful power-on, self-checking after power-on without exception, etc. The air conditioner outlet temperature can be measured by a temperature sensor and can include the air conditioner outlet temperature, etc. The sunlight intensity can be measured by a light intensity measuring unit.

[0113] The light intensity measuring unit can include a photodiode light intensity measuring instrument, a CCD light intensity detector, a photoresistor sensor, and a photoelectron sensor, etc.

[0114] S221: determining the indoor temperature as the front head temperature, the interior material temperature, and the sunlight material temperature.

[0115] In this step, the indoor temperature can be the indoor temperature calculated in any of the above embodiments, and is the indoor temperature calculated at the time of vehicle initialization or power-on.

[0116] For example, if the indoor temperature is 17°C, the front head temperature, the interior material temperature, and the sunlight material temperature are all set to 17°C. The value of the indoor temperature can be measured in different situations by any of the above embodiments, or can be a value other than 17°C.

[0117] S222: determining the outdoor temperature as the exterior material temperature.

[0118] In this step, the outdoor temperature can be obtained in step S201. The outdoor temperature is assigned to the exterior material temperature.

[0119] S223: determining a new front head temperature according to the front head temperature, the air conditioner outlet temperature, the exterior material temperature, and the sunlight material temperature.

[0120] In this step, the front head temperature, the air conditioner outlet temperature, the exterior material temperature, and the sunlight material temperature can be input into a preset front head temperature calculation equation to obtain the new front head temperature.

[0121] The front head temperature calculation equation can be preset by a worker according to experimental data or experience. The form of the front head temperature calculation equation can be as follows:

[0122] T 1h(t+1) = T 1h(t) + f (air conditioner outlet temperature) + f (interior material temperature) + f (exterior material temperature) + f (sunlight material temperature)

[0123] In the formula, T 1h(t+1) represents the new front head temperature; T 1h(t) represents the existing front head temperature; f (air conditioner outlet temperature) represents the influence of the existing air conditioner outlet temperature on the front head temperature; f (interior material temperature) represents the influence of the existing interior material temperature on the front head temperature; f (exterior material temperature) represents the influence of the existing exterior material temperature on the front head temperature; and f (sunlight material temperature) represents the influence of the existing sunlight material temperature on the front head temperature.

[0124] In the calculation process, the front head temperature is inputted as T 1h(t) , the air conditioner outlet temperature is inputted as f (air conditioner outlet temperature), the interior material temperature is inputted as f (interior material temperature), the exterior material temperature is inputted as f (exterior material temperature), and the sunlight material temperature is inputted as f (sunlight material temperature) to obtain the new front head temperature.

[0125] S224: determining the new interior material temperature according to the interior material temperature and the front head temperature.

[0126] In this step, the interior material temperature and the front head temperature can be inputted into a preset interior material temperature calculation equation to obtain the new interior material temperature, similar to the above step S223.

[0127] The form of the interior material temperature calculation equation is as follows:

[0128] T i(t+1) = T i(t) + f (front head temperature)

[0129] In the formula, T i(t+1) represents the next time interior material temperature; T i(t) represents the existing time interior material temperature; and f (front head temperature) represents the influence of the existing front head temperature on the interior material temperature. The calculation process is similar to the above step S223, and will not be described here.

[0130] S225: determining the new sunlight material temperature according to the sunlight material temperature, the front head temperature and the sunlight intensity.

[0131] In this step, the sunlight material temperature, the front head temperature and the sunlight intensity can be inputted into a preset sunlight material temperature calculation equation to obtain the new sunlight material temperature.

[0132] Wherein, the sunlight material temperature calculation formula can be set by the staff in advance, and the form is as follows:

[0133] T s(t+1) = T s(t) +f(front row head temperature)+f(sunlight intensity)

[0134] In the formula, T s(t+1) represents the sunlight material temperature at the next moment; T s(t) represents the sunlight material temperature; f(front row head temperature) represents the influence of the front row head temperature on the sunlight material temperature; and f(sunlight intensity) represents the influence of the sunlight intensity on the sunlight material temperature. The calculation process is similar to the above step S223, and will not be described here.

[0135] S226: Determine a new vehicle interior temperature according to the new front row head temperature, the new interior material temperature and the new sunlight material temperature.

[0136] In this step, the new front row head temperature, the new interior material temperature and the new sunlight material temperature can be input into the vehicle interior temperature calculation formula to obtain the new vehicle interior temperature.

[0137] Wherein, the vehicle interior temperature calculation formula is as follows: T incar =a·T 1h +b·T i +c·T s

[0138] In the formula, T incar represents the new vehicle interior temperature, T 1h represents the new front row head temperature, T i represents the new interior material temperature, T s represents the new sunlight material temperature, and a, b and c are coefficients set by the staff according to experimental data or experience, and a>b>c.

[0139] Wherein, a is for example 0.55, b is for example 0.4, and c is for example 0.05. Each coefficient can also take other values.

[0140] As can be seen from the description of the above embodiments, the embodiments of the present application calculate the vehicle interior temperature after power-on by combining the air conditioner outlet temperature, the sunlight intensity, the front row head temperature, the interior material temperature, the exterior material temperature and the sunlight material temperature, so that the vehicle interior temperature can be obtained without setting a vehicle interior temperature sensor, thereby reducing the manufacturing cost of the vehicle.

[0141] In a possible implementation, after determining the new vehicle interior temperature in the above step S226, the method further includes:

[0142] S227: Determine a new exterior material temperature according to the exterior material temperature, the front head temperature and the outside temperature.

[0143] In this step, the exterior material temperature, the front head temperature and the outside temperature are input into a preset exterior material temperature calculation formula to obtain the new exterior material temperature.

[0144] The exterior material temperature calculation formula is in the following form:

[0145] T e(t+1) = T e(t) + f(front head temperature) + f(outside temperature)

[0146] T e(t+1) represents the new exterior material temperature; T e(t) represents the existing exterior material temperature; f(front head temperature) represents the influence of the existing front head temperature on the exterior material temperature; and f(outside temperature) represents the influence of the outside temperature on the exterior material temperature. In the present embodiment and the previous embodiment, "(t)" can represent the quantity used or calculated this time, such as the front head temperature, the exterior material temperature, etc., and "(t+1)" can represent the quantity used or calculated next time, such as the new front head temperature, the new exterior material temperature, etc.

[0147] S228: Re-execute the steps of determining the new front head temperature to determining the new vehicle temperature by using the air outlet temperature of the air conditioner, the sunlight intensity, the new front head temperature, the new interior material temperature, the new sunlight material temperature and the new exterior material temperature.

[0148] In this step, the steps of determining the new front head temperature to determining the new vehicle temperature can be the steps S223 to S226 described above.

[0149] As can be seen from the description of the above embodiments, the present application determines the new exterior material temperature by using the exterior material temperature, the front head temperature and the outside temperature, which facilitates the subsequent update of the front head temperature by using the new exterior material temperature and the continuous update of the vehicle temperature, so that the vehicle temperature can be continuously updated after power-on without the temperature sensor in the vehicle, thereby reducing the manufacturing cost of the vehicle.
