[0061] The technical solutions of the present application will be described in detail below with reference to the drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0062] Figure 1 A flowchart of the vehicle-mounted air conditioner detection method provided by one or more embodiments of the present application is shown in the figure.

[0063] As shown in the figure, the vehicle-mounted air conditioner detection method comprises: Figure 1

[0064] Step S1, presetting instruction data of the vehicle-mounted air conditioner;

[0065] Step S2, collecting temperature data of an air outlet of the vehicle-mounted air conditioner according to the instruction data of the vehicle-mounted air conditioner;

[0066] Step S3, drawing a temperature change curve according to the temperature data of the air outlet of the vehicle-mounted air conditioner;

[0067] Step S4, setting a data evaluation feature based on the temperature change curve;

[0068] Step S5, evaluating the temperature change curve according to the data evaluation feature to obtain working capability state information of the vehicle-mounted air conditioner.

[0069] Specifically, in the present embodiment, the vehicle-mounted air conditioner is separated from the specific vehicle machine control, and a control for controlling only the instruction data of the vehicle-mounted air conditioner is separately set. Only the data of refrigeration and heating at the air outlet is collected under the preset cabin environment with a fixed preset air speed, and the performance of the vehicle-mounted air conditioner is evaluated. That is, the influence of the air duct, pipeline and heat exchange in the air conditioner assembly design on the refrigeration and heating function of the cabin environment is excluded, and the performance of the vehicle-mounted air conditioner in the cabin environment is accurately evaluated.

[0070] In the case of fixed other elements during data collection, only the temperature curve data of the air outlet of the air conditioner needs to be collected, and the working capability state information of the vehicle-mounted air conditioner is obtained through the set data evaluation feature based on the temperature change curve.

[0071] In the present embodiment, the instruction data of the vehicle-mounted air conditioner comprises:

[0072] Referring to a preset temperature threshold, an instruction of refrigeration or heating is issued;

[0073] ​The control outlet maintains the wind speed in a preset wind speed threshold interval;

[0074] According to the instruction of refrigeration or heating, the sampling period is set and the temperature data is sampled.

[0075] Specifically, in this embodiment, the starting point of data sampling, such as the starting point of ambient temperature, the starting point of wind speed state, etc., is sampled according to the preset sampling interval, such as time interval, temperature interval, etc. Generally, the instruction of heating is issued from the preset minimum temperature starting point, or the instruction of refrigeration is issued from the preset maximum temperature starting point, and the working capacity of the vehicle air conditioner is evaluated by drawing a curve of outlet temperature sampling and fitting with a preset performance curve.

[0076] In this embodiment, it also includes:

[0077] Obtaining refrigeration mode data of the vehicle air conditioner;

[0078] The refrigeration mode data includes polynomial data for drawing a temperature change curve based on refrigeration in refrigeration mode;

[0079] The polynomial data corresponding to the refrigeration mode includes,

[0080] y1=-0.0024x 3 +0.1873x 2 -4.9639x+49.628;

[0081] Wherein, y is the temperature axis, x is the time axis, and y1 is the temperature data sample point accompanying the change of time in refrigeration mode.

[0082] Specifically, in this embodiment, the polynomial y1=-0.0024x 3 +0.1873x 2 -4.9639x+49.628 is obtained, which is calculated by the specific vehicle type and cabin space style, etc., and a reference curve of temperature change curve as a standard is drawn by the polynomial.

[0083] In addition, the instruction of refrigeration mode is issued to the vehicle air conditioner, and the fitting degree of the curve drawn and the reference curve formed by the polynomial is compared, so as to judge whether the refrigeration capacity of the vehicle air conditioner in refrigeration mode meets the expectation.

[0084] In this embodiment, it also includes:

[0085] Obtaining refrigeration mode data of the vehicle air conditioner;

[0086] The polynomial data corresponding to the refrigeration mode includes,

[0087] y2=0.0059x3 -0.944x 2 +50.15x-809.6;

[0088] Wherein, y is temperature axis, x is time axis, y2 is temperature data sample point changing with time in heating mode.

[0089] Specifically, in this embodiment, the polynomial y2 = 0.0059x 3 -0.944x 2 +50.15x-809.6 is obtained, which is calculated by the specific vehicle cabin space style and the like, and a reference curve of temperature change curve is drawn by the polynomial as a standard.

[0090] In addition, the temperature data of the air outlet of the vehicle air conditioner is used to compare the fitting degree of the drawn curve and the reference curve formed by the polynomial, so as to determine whether the heating capacity of the vehicle air conditioner in the heating mode meets the expectation.

[0091] In this embodiment, it also includes:

[0092] According to the temperature data sample points changing with time of y1 and y2, the coincidence points of the temperature data sample points are set;

[0093] According to the set coincidence points of the temperature data sample points, a preset temperature threshold is set;

[0094] According to the comparison of the temperature data value collected from the air outlet of the vehicle air conditioner and the preset temperature threshold, the time when the cooling or heating instruction is issued to switch the cooling mode or the heating mode is set;

[0095] According to the continuous work of the vehicle air conditioner reciprocating between the cooling mode and the heating mode, a temperature change curve is drawn;

[0096] According to the drawn temperature change curve, the working capacity state information of the vehicle air conditioner is obtained.

[0097] Specifically, in this embodiment, the cooling and heating instructions of the vehicle air conditioner can be issued at will, and the most difficult thing is to reach another "extreme" temperature from one "extreme" temperature. The air in the cabin heated by the vehicle air conditioner includes other materials contributing to the specific heat capacity in addition to the air in the cabin, resulting in less flowability of heat than air medium. By continuous and repeated heating mode and cooling mode continuous work, a continuous periodic waveform is drawn. A plurality of periodic waveforms are sampled, in the temperature rising stage, the curve of y2 = 0.0059x 3 -0.944x 2 +50.15x-809.6 is taken for comparison, and in the temperature falling stage, the curve of y1 = -0.0024x 3+0.1873x 2 -4.9639x+49.628 of the curve, so as to obtain the information of the continuous working ability of the vehicle air conditioner. For example, whether the heating or cooling effect is high enough is viewed from the time period, or whether the heating or cooling effect is high enough is viewed from the amplitude.

[0098] In the embodiment, further comprising:

[0099] Obtaining data evaluation features;

[0100] The data evaluation features comprise comparing the time delay of the x-axis based on the temperature data sample alignment of the y-axis;

[0101] The data evaluation features further comprise comparing the temperature deviation of the y-axis based on the time data sample alignment of the x-axis.

[0102] Specifically, in the embodiment, when fitting the curve for comparison, the same period can be selected to observe the "amplitude of the waveform" to express the efficiency of cooling or heating, and the same amplitude can also be used to express the efficiency of cooling or heating.

[0103] It is not excluded that there is a large difference between the heating and cooling efficiency of the vehicle air conditioner, such as the heating efficiency being much higher than the cooling efficiency. By aligning the temperature data sample of the y-axis or aligning the time data sample of the x-axis, the deviation state in the fitting curve process is observed.

[0104] Figure 2 is a structural diagram of a vehicle air conditioner detection device provided by one or more embodiments of the application.

[0105] As shown in Figure 2 The vehicle air conditioner detection device comprises an instruction data module, a data acquisition module, a curve data module, an evaluation feature module, and a state evaluation module.

[0106] The instruction data module is used to preset the instruction data of the vehicle air conditioner.

[0107] The data acquisition module is used to acquire the temperature data of the air outlet of the vehicle air conditioner according to the instruction data of the vehicle air conditioner.

[0108] The curve data module is used to draw a temperature change curve according to the temperature data of the air outlet of the vehicle air conditioner.

[0109] The evaluation feature module is used to set data evaluation features based on the temperature change curve.

[0110] The state evaluation module is used to evaluate the temperature change curve according to the data evaluation features, and obtain the working ability state information of the vehicle air conditioner.

[0111] It is worth noting that although the system only discloses the instruction data module, the data acquisition module, the curve data module, the evaluation feature module, and the state evaluation module, it does not mean that the device is limited to the above basic function modules. On the contrary, the meaning expressed by the present application is that on the basis of the above basic function modules, a person skilled in the art can add one or more function modules to form an infinite number of embodiments or technical solutions in combination with the prior art. That is to say, the system is open rather than closed, and the protection scope of the present application claimed in the present embodiment cannot be limited to the above disclosed basic function modules.

[0112] Through the above scheme, the following beneficial technical effects are obtained:

[0113] The present application sets the instruction data for controlling the air conditioner and sets the data evaluation feature of the temperature change curve, tests according to the preset environment, so as to eliminate the unstable influence of the experimental environment brought by the specific working environment.

[0114] The present application continuously controls the air conditioner refrigeration and heating, and obtains the performance problem of the air conditioner module itself through the curve change, so as to distinguish the relationship between the air conditioner and the vehicle.

[0115] The present application strips the preset environment unstable elements brought by the cabin environment style and the air conditioner assembly by presetting the air speed and the room temperature, so that the measured air conditioner performance is stripped from the influence of the cabin style and the installation scheme, so that the air conditioner test result becomes stable and reliable.

[0119] In one specific embodiment, the temperature control process curve as shown in Figure 3 is generated according to the data records in Table 1.

[0120] Table 1

[0121]

[0122]

[0123]

[0124]

[0125] In which, the serial number 1 to 5 is the preparatory stage, sampling natural room temperature as the starting point, start the refrigeration mode, no 5 seconds to do a temperature data sampling, when reaching the preset "low temperature limit" 5 degrees Celsius, immediately converted to heating mode, when reaching the preset "high temperature limit" 83 degrees Celsius, form a group of data cycle waveform. In which, the temperature of the air outlet of the air conditioner in the embodiment is sampled, and the influence of the room temperature or the influence of the room temperature is no longer considered since the refrigeration mode is started. Denoted by " ".

[0126] Specifically, 1, during use, first turn on the temperature switch and the time counting switch, and start recording the temperature and time change value. 2, the 6th group of data to the 29th group of data is the effective data of the air conditioner refrigeration, during which the air volume of the air conditioner is adjusted to the maximum, the temperature is adjusted to the lowest temperature displayed by the vehicle, and the temperature and time change rule of the vehicle air outlet temperature from the room temperature to the lowest temperature under the control of the lowest temperature of the vehicle is observed. 3, when the temperature of the vehicle is reduced to the lowest, keep a certain time without reducing, without changing the air volume, adjust the temperature of the air conditioner to the highest temperature. The 29th group of data to the 31st group of data is the data of the vehicle air outlet temperature keeping the lowest value and not changing. 4, the 31st group of data to the 62nd group of data is the effective data of the air conditioner heating, and the temperature and time change curve from the lowest temperature of the vehicle to the highest temperature.

[0127] Of course, the actual application will not reach the limit of 5 degrees Celsius and 83 degrees Celsius, but only through the experiment to confirm the capacity range of the vehicle air conditioner.

[0128] In the embodiment, the refrigeration fitting simulation curve diagram is shown in Figure 4 , and the heating fitting simulation curve diagram is shown in Figure 5 . The actual sampling point curve and the pre-designed curve are fitted, and the performance of the vehicle air conditioner is judged by observing the deviation degree. (In the figure, the actual sampling point curve is according to 5 second interval)

[0129] For example, the polynomial in the refrigeration mode is: y1=-0.0024x3+0.1873x2-4.9639x+49.628; in the figure, the 6th group of data to the 29th group of data is the effective data of the air conditioner refrigeration, wherein X is the time axis, Y is the temperature axis, the temperature decreases with time, and the refrigeration capacity of the entire air conditioner system of the vehicle reaches the limit state when the temperature does not decrease.

[0130] For example, in the heating mode, the polynomial is: y2=0.0059x3-0.944x2+50.15x-809.6; in the figure, the 31st to 62nd data are the effective data of the air conditioner heating, wherein X is the time axis, Y is the temperature axis, the temperature increases with time until the temperature does not increase, at which time the refrigeration capacity of the entire air conditioning system of the vehicle reaches the limit state.

[0131] In another specific embodiment, the temperature of the vehicle air conditioning system is detected (for example, in the refrigeration mode of the vehicle, the polynomial is: y1=-0.0024x3+0.1873x2-4.9639x+49.628; in the heating mode, the polynomial is: y2=0.0059x3-0.944x2+50.15x-809.6).

[0132] The parameters of interest are the minimum temperature T1, which for this vehicle model is 5°;

[0133] The parameters of interest are the maximum temperature T2, which for this vehicle model is 83°;

[0134] The focus is on whether the temperature-time curve from room temperature to minimum temperature conforms to the y1 function (in this embodiment, a certain vehicle model is taken as an example, and for other different vehicle models, the y1 function is not consistent, but the evaluation method is consistent);

[0135] The focus is on whether the temperature-time curve from the minimum temperature to the maximum temperature conforms to the y2 function (in this embodiment, a certain vehicle model is taken as an example, and for other different vehicle models, the y2 function is not consistent, but the evaluation method is consistent);

[0136] During the detection process, the minimum temperature does not conform to T1, i.e. the air conditioning system is not completely refrigerated;

[0137] During the detection process, the minimum temperature does not conform to T2, i.e. the air conditioning system is not completely heated;

[0138] During the detection process, the temperature-time curve from room temperature to minimum temperature does not conform to the y1 function, i.e. the air conditioning system is not completely refrigerated;

[0139] During the detection process, the temperature-time curve from the minimum temperature to the maximum temperature does not conform to the y2 function, i.e. the air conditioning system is not completely heated.

[0140] In the embodiment, 1, the temperature change data collected by the air conditioning system of the vehicle is calibrated. 2, according to the temperature change data of the air conditioning system of the vehicle, the function curve and formula of the refrigeration mode of the vehicle from normal temperature to the lowest temperature are fitted, and the function curve and formula of the heating mode of the vehicle from the lowest temperature to the highest temperature are fitted. 3, in the actual working process, it is difficult to ensure that every vehicle is tested for refrigeration mode function curve and heating mode function curve, which is time-consuming and laborious, and is not convenient. 4, taking the vehicle as an example: after opening the refrigeration mode, the current temperature is recorded as 18°. The refrigeration mode function y1=-0.0024x3+0.1873x2-4.9639x+49.628 is brought in. It can be obtained that y1 is about 9.17; after 30 seconds, the current temperature value is recorded. Compared with the temperature value 9° obtained by calculating y1+30. If it is within ±1° of 9°, it is defaulted to comply with the change curve rule. Otherwise, it does not comply with the curve change rule, if it complies, it can prove that the refrigeration function of the air conditioning system is normal and complies with the refrigeration mode function curve of the air conditioning system calibration vehicle. 5, taking the vehicle as an example: after opening the refrigeration mode, the heating mode is started, and the current temperature is recorded as 20°. The heating mode function y2=0.0059x3-0.944x2+50.15x-809.6 is brought in. It can be obtained that y2 is about 31.765; after 30 seconds, the current temperature value is recorded. Compared with the temperature value 55.7° obtained by calculating y2+30. If it is within ±2° of 55.7°, it is defaulted to comply with the change curve rule. Otherwise, it does not comply with the curve change rule, if it complies, it can prove that the heating function of the air conditioning system is normal and complies with the heating mode function curve of the air conditioning system calibration vehicle.
