[0043] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present application.

[0044] In order to make the purpose, technical solutions and advantages of the present application clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0045] Figure 1 A flowchart of a method for controlling the temperature of a passenger compartment provided in an embodiment of the present application is described in detail as follows:

[0046] Step 101, obtaining the current temperature of the passenger compartment, and determining the target temperature change rate and the actual temperature change rate corresponding to the current temperature of the passenger compartment.

[0047] When obtaining the current temperature of the passenger compartment, it is necessary to collect it once every preset time, for example, once every 2 seconds, 3 seconds, 4 seconds, etc., so as to quickly detect the temperature changes caused by changes in the fan opening of the cooling fan and the operating power of the air-conditioning compressor.

[0048] In some embodiments, according to the current temperature of the passenger compartment, the corresponding target temperature change rate ΔT is determined by searching in the first preset table. 目标 , the first preset table includes the corresponding relationship between the passenger compartment temperature and the target temperature change rate. Among them, the target temperature change rate is consistent with or opposite to the change trend of the current temperature of the passenger compartment. For example, when cooling is needed in summer, the target temperature change rate increases with the increase of temperature and decreases with the decrease of temperature. This can ensure that the current temperature of the passenger compartment is quickly cooled down, quickly reaches a temperature that the user feels comfortable, and then slowly cools down to the target temperature to improve the user experience. When heating is needed in winter, the target temperature change rate decreases with the increase of temperature and increases with the decrease of temperature. This can ensure that the current temperature of the passenger compartment is quickly heated up, quickly reaches a temperature that the user feels comfortable, and then slowly heats up to the target temperature to improve the user experience.

[0049] For example, when the temperature is 30°C, the target temperature change rate may be 1, when the temperature is 28°C, the target temperature change rate may be 0.8, when the temperature is 26°C, the target temperature change rate may be 0.6, when the temperature is 25°C, the target temperature change rate may be 0.5, when the temperature is 22°C, the target temperature change rate may be 0.2, when the temperature is 20°C, the target temperature change rate may be 0.1, etc. It should be noted that the target temperature change rate may be set according to different requirements, and the value of the target temperature change rate is not limited in this embodiment, and the above is only an exemplary description.

[0050] The method for determining the actual temperature change rate corresponding to the current temperature of the passenger compartment includes:

[0051] Get the last detected cabin temperature and the corresponding time, calculate the difference between the current cabin temperature and the last detected cabin temperature, and divide it by the time difference between the two temperature measurements to get the actual temperature change rate corresponding to the current cabin temperature. The actual temperature change rate corresponding to the current temperature of the passenger compartment is calculated, where ΔT 实际 It represents the actual temperature change rate, T1 represents the current temperature of the passenger compartment or the last detected passenger compartment temperature, T2 represents the last detected passenger compartment temperature or the current temperature of the passenger compartment, and t represents the time difference between the two temperature measurements.

[0052] Step 102: Calculate the difference between the actual temperature change rate and the target temperature change rate.

[0053] In some embodiments, this step can be performed according to T = ΔT 实际 -ΔT 目标 Calculate the difference between the actual temperature change rate and the target temperature change rate.

[0054] Step 103 : when the absolute value of the difference is greater than a preset threshold, adjusting the fan opening of the cooling fan and / or the operating power of the air-conditioning compressor to reduce the difference.

[0055] When the absolute value of the difference between the actual temperature change rate and the target temperature change rate is greater than the preset threshold, it means that the actual temperature change rate has not reached the target temperature change rate. If the temperature continues to be lowered or raised according to the current air-conditioning compressor power and the current fan opening, the user's comfortable temperature cannot be reached quickly. Therefore, it is necessary to adjust the current air-conditioning compressor power and / or the current fan opening.

[0056] The value of the preset threshold can be calibrated. In this embodiment, the value of the preset threshold is not limited. For example, the preset threshold can be 0.02, 0.03, 0.05, etc.

[0057] In some embodiments, adjusting the fan opening of the cooling fan and / or the operating power of the air conditioning compressor to reduce the difference between the actual temperature change rate and the target temperature change rate may include:

[0058] The corresponding first coefficient and second coefficient are determined based on the difference between the actual temperature change rate and the target temperature change rate and the target temperature change rate; the adjusted fan opening is determined based on the product of the first coefficient and the current fan opening of the cooling fan, and the cooling fan is adjusted to the adjusted fan opening; the adjusted operating power is determined based on the product of the second coefficient and the current operating power of the air-conditioning compressor, and the air-conditioning compressor is adjusted to the adjusted operating power.

[0059] In some specific embodiments, the corresponding first coefficient and second coefficient can be determined by searching in the second preset relationship table according to the difference and the target temperature change rate, such as Figure 2 As shown, the second preset relationship table includes the corresponding relationship between the difference, the target temperature change rate and the coefficient combination, and the coefficient combination includes a first coefficient K1 and a second coefficient K2.

[0060] The first coefficient and the second coefficient can be calibrated through experiments. The calibration method of the first coefficient and the second coefficient includes: fixing the fan opening of the cooling fan and the operating power of the air-conditioning compressor, obtaining the changed fan opening by changing the first coefficient corresponding to the fan opening, and obtaining the changed operating power by changing the second coefficient corresponding to the operating power of the air-conditioning compressor. In this way, multiple sets of reasonable first coefficients and second coefficients can be obtained, so that the difference between the corresponding actual temperature change rate and the target temperature change rate is less than or equal to the preset threshold value. These sets of first coefficients and second coefficients are reasonable, but we need to consider the overall power value to be minimum, that is, through P=K1P Fan +K2P CMP After calculating different total powers, select the first coefficient and the second coefficient corresponding to the minimum total power and record them in the second preset table. The difference and the target temperature change rate are the corresponding values ​​before the fan opening and the air conditioning compressor operating power are adjusted. It should be noted that the fan power can be obtained by the fan opening.

[0061] That is, the cooling fan is controlled to operate at an initial fan opening, and the air-conditioning compressor is controlled to operate at an initial operating power; the current temperature of the passenger compartment is obtained, the target temperature change rate and the actual temperature change rate corresponding to the current temperature of the passenger compartment are determined, and the difference between the actual temperature change rate and the target temperature change rate is calculated; when the absolute value of the difference is greater than a preset threshold, a first adjustment coefficient and a second adjustment coefficient are set, the initial fan opening is multiplied by the first adjustment coefficient to obtain an adjusted fan opening, and the initial operating power is multiplied by the second adjustment coefficient to obtain an adjusted operating power; when the cooling fan is operated at the adjusted fan opening and the air-conditioning compressor is operated at the adjusted operating power, when the difference between the corresponding actual temperature change rate and the target temperature change rate is less than or equal to the preset threshold, the first adjustment coefficient and the second adjustment coefficient are determined to be the initial target coefficient group; based on all initial target coefficient groups, according to P=K1P Fan +K2P CMP , calculate the corresponding total power; where P represents the total power, K1 represents the first coefficient in the initial target coefficient, P Fan represents the initial fan opening, K2 represents the second coefficient in the initial target coefficient, P CMP Indicates the initial operating power of the air-conditioning compressor; determines the initial target coefficient group corresponding to the minimum total power among all total powers as the target coefficient, and the target coefficient includes the corresponding first coefficient and second coefficient.

[0062] After obtaining the second preset table, the fan opening of the cooling fan and / or the operating power of the air-conditioning compressor can be adjusted through K1 and K2 calibrated in the second preset table, so that the total power obtained is the minimum power, and at this time the target temperature change rate corresponding to the passenger compartment temperature is also met.

[0063] In some embodiments, when other components also have heat dissipation requirements, and the fan opening is greater than the required fan opening, a larger fan opening should be opened to meet the needs of the entire vehicle. At this time, because the fan opening becomes larger, the power of the air-conditioning compressor can be reduced to achieve a constant and stable temperature change rate and energy saving requirements. Therefore, when adjusting the current air-conditioning compressor power and / or the current fan opening, the following methods can also be used:

[0064] When it is detected that the fan opening of the cooling fan is greater than or equal to the requested fan opening, reducing the operating power of the air conditioning compressor;

[0065] When it is detected that the fan opening of the cooling fan is less than the requested fan opening, the operating power of the air conditioning compressor is increased;

[0066] When it is detected that the fan opening degree of the heat dissipation fan is less than the requested fan opening degree, the fan opening degree of the heat dissipation fan is increased.

[0067] It should be noted that when it is detected that the current fan opening is less than the requested fan opening, among the two different adjustment methods of increasing the operating power of the air-conditioning compressor or increasing the fan opening of the cooling fan, the selected adjustment method is the one that minimizes the sum of the adjusted fan power and the operating power of the air-conditioning compressor.

[0068] In some embodiments, when the absolute value of the difference is greater than a preset threshold value, the fan opening of the cooling fan and / or the operating power of the air-conditioning compressor can be adjusted according to a preset adjustment range. For example, the operating power of the air-conditioning compressor is subtracted from the preset operating power to obtain the adjusted operating power, or the operating power of the air-conditioning compressor is added to the preset operating power to obtain the adjusted operating power. The value of the preset operating power can be set according to actual needs. For example, the fan opening is subtracted from the preset opening, or the fan opening is added to the preset opening to obtain the adjusted fan opening. The value of the preset opening can be set according to actual needs. It should be noted that the value of the preset operating power or the value of the preset opening can be set smaller so that the fan opening of the cooling fan and / or the operating power of the air-conditioning compressor can be accurately adjusted. However, the value of the preset operating power or the value of the preset opening cannot be too small to avoid extending the adjustment time.

[0069] It should be noted that when the vehicle is first turned on, the fan opening and the air-conditioning compressor power are operated at the user's requested fan opening and air-conditioning compressor power, and then the fan opening and the air-conditioning compressor operating power are gradually adjusted through the adjustment method described above.

[0070] In some embodiments, after calculating the difference between the actual temperature change rate and the target temperature change rate, it also includes: when the absolute value of the difference is less than or equal to a preset threshold, keeping the air conditioning compressor running at the current operating power, and keeping the cooling fan running at the current fan opening.

[0071] In some embodiments, when the absolute value of the difference between the actual temperature change rate and the target temperature change rate is less than or equal to a preset threshold, it indicates that the actual temperature change rate has reached the target temperature change rate, and the temperature can continue to be controlled according to the current operating power of the air-conditioning compressor and the fan opening of the cooling fan.

[0072] The above passenger compartment temperature control method calculates the difference between the actual temperature change rate and the target temperature change rate, and determines the target operating power and target fan opening of the air-conditioning compressor that meet the conditions according to the relationship between the absolute value of the difference and the preset threshold, thereby quickly adjusting the temperature of the passenger compartment to the passenger compartment comfort level, meeting user needs, and improving user experience. In addition, by calibrating the first coefficient and the second coefficient in the second preset table, the total power corresponding to the target operating power and target fan opening of the air-conditioning compressor that meet the conditions can be made the minimum total power, thereby achieving the goal of reducing power consumption.

[0073] It should be understood that the size of the serial numbers of the steps in the above embodiments does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present application.

In addition, by calibrating the first coefficient and the second coefficient in the second preset table, the total power corresponding to the target operating power of the air-conditioning compressor and the target fan opening that meet the conditions can be made the minimum total power, thereby achieving the goal of reducing power consumption.
