[0040] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of a heat pump function detection device in the hardware operating environment involved in the embodiment of the present invention.

The wired interface of the user interface 1003 may be a USB interface in the present invention. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM), or a stable memory (Non-volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0042] Those skilled in the art will understand that Figure 1 The structure shown in does not constitute a limitation on the heat pump function detection device, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

[0043] like Figure 1 As shown, the memory 1005 identified as a computer storage medium may include an operating system, a network communication module, a user interface module, and a heat pump function detection program.

[0044] exist Figure 1 In the heat pump function detection device shown, the network interface 1004 is mainly used to connect to the background server and communicate data with the background server; the user interface 1003 is mainly used to connect to the user device; the heat pump function detection device calls the heat pump function detection program stored in the memory 1005 through the processor 1001, and executes the heat pump function detection method provided in the embodiment of the present invention.

[0045] Based on the above hardware structure, an embodiment of the heat pump function detection method of the present invention is proposed.

[0046] Reference Figure 2 , Figure 2 The figure is a flow chart of the first embodiment of the heat pump function detection method of the present invention, and provides the first embodiment of the heat pump function detection method of the present invention.

[0047] In this embodiment, the heat pump function detection method includes the following steps:

[0048] Step S10: upon receiving the heat pump function detection start instruction, obtaining the current ambient temperature.

[0049] It should be noted that the execution subject of this embodiment may be a device including a heat pump function detection system, such as: a car computer, a notebook, etc. This embodiment is described using a heat pump function detection device, and this embodiment does not limit this. In this embodiment and the following embodiments, the heat pump function detection method of the present invention is described using a heat pump function detection device as an example.

[0050] It can be understood that the heat pump function detection start instruction refers to the heat pump function detection instruction turned on through the combination operation form of the air-conditioning control panel, and the combination operation form of the air-conditioning control panel refers to the function detection when the whole vehicle is produced and the function detection during after-sales service through the combination operation form as the function entry channel form.

[0051] It should be understood that the current ambient temperature is the natural ambient temperature collected by the sensor.

[0052] Step S20: determining the working mode corresponding to the air-conditioning controller according to the current ambient temperature, and controlling the heat pump system to perform a heat pump function test according to a preset program according to the working mode to obtain a function test result.

[0053] It should be noted that the air conditioning controller can be connected to the air conditioning control panel wirelessly or wiredly, so that the thermal management system can be adjusted through the air conditioning control panel. The air conditioning controller can be a controller including an air conditioning control system, and the air conditioning control system is composed of a refrigeration system, a heating system, a ventilation system, and an air purification device and a control system. The controller is a device for adjusting the automobile air conditioning system, and the automobile air conditioning system has functions such as refrigeration, ventilation, and defrosting. This embodiment does not specifically limit the type of air conditioning controller.

[0054] It is understandable that the heat pump system can be a system for heating the cab by utilizing the thermal energy in the outside air and the waste heat of the driving device. The heat pump system is mainly composed of a compressor, an evaporator, an expansion valve and a condenser. In this scheme, in order to accurately detect whether the components of the heat pump function in the heat pump system are normal, the working signals of the water pump, electronic expansion valve, stop valve, three-way valve and other components associated with the heat pump function are detected to determine whether the vehicle heat pump function is abnormal.

[0055] It should be understood that the preset program is used to detect whether the components of the heat pump function in the heat pump system are normal and obtain the functional test results of each component. The preset program is a pre-set program for the heat pump system to perform functional self-test.

[0056] In a specific implementation, the working mode corresponding to the air-conditioning controller is determined according to the current ambient temperature, and the heat pump system is controlled to perform heat pump function detection according to a preset program according to the working mode of the air-conditioning controller to obtain a function detection result.

[0057] Step S30: determining fault information of components related to the heat pump function in the heat pump system according to the function detection result, and sending the fault information to the central control screen for display.

[0058] It should be noted that the heat pump function-related components in the heat pump system refer to the heat pump independent-related components, among which the heat pump independent-related components refer to the heat pump working circuit components after removing the air-conditioning refrigeration circuit components. The heat pump working circuit components include the electronic expansion valve, stop valve, three-way proportional valve, etc. in the refrigerant heating circuit. The above components all use LIN communication and exchange data with the air-conditioning controller through the LIN bus.

[0059] It is understandable that the fault information includes system fault codes, component fault codes and fault signals.

[0060] This embodiment obtains the current ambient temperature upon receiving a heat pump function detection start instruction; determines the working mode corresponding to the air-conditioning controller according to the current ambient temperature, and controls the heat pump system to perform the heat pump function detection according to a preset program according to the working mode to obtain a function detection result; determines the fault information of the heat pump function-related components in the heat pump system according to the function detection result, and sends the fault information to the central control screen for display. Compared with the prior art, which cannot avoid the influence of temperature on the realization of the heat pump function, resulting in the inability to complete the inspection of the whole vehicle function and low productivity, this embodiment avoids the influence of temperature on the realization of the function through a control method, completes the inspection of the whole vehicle function, and improves production efficiency and vehicle reliability.

[0061] Reference Figure 3 , Figure 3 This is a flow chart of the second embodiment of the heat pump function detection method of the present invention. Figure 2 The first embodiment shown provides a second embodiment of the heat pump function detection method of the present invention.

[0062] In this embodiment, step S20 includes:

[0063] Step S201: determining the working mode corresponding to the air conditioning controller according to the current ambient temperature and the preset temperature.

[0064] It should be noted that the preset temperature is a pre-set ambient temperature used to determine whether the heat pump system is automatically activated. When the current ambient temperature is lower than the preset ambient temperature, the heat pump system startup conditions are met, and the heat pump system is controlled to operate according to the corresponding working mode of the air-conditioning controller. When the current ambient temperature is not lower than the preset ambient temperature, the heat pump system startup conditions are not met, and the independent related components in the heat pump system are controlled to operate and self-check according to the corresponding working mode of the air-conditioning controller.

[0065] Step S202: According to the working mode, the heat pump system is controlled to perform a heat pump function test according to a preset program to obtain a function test result.

[0066] It should be noted that the functional test results include: when the heat pump system startup conditions are met, the heat pump system is controlled to work according to the working mode corresponding to the air-conditioning controller. The component function test results when the heat pump system startup conditions are not met and the independent related components in the heat pump system are controlled to operate and self-check according to the working mode corresponding to the air-conditioning controller.

[0067] In the specific implementation, the corresponding working mode of the air-conditioning controller is determined according to different ambient temperatures, and the heat pump system is controlled according to the corresponding working mode of the air-conditioning controller to perform system operation detection to obtain system function detection results and component function detection results obtained by self-testing the independent related components of the heat pump function.

[0068] Further, the step S201 includes: when the current temperature is lower than a preset temperature, controlling the heat pump system to operate according to preset conditions; when the current temperature is not lower than the preset temperature, cutting off the operation of the compressor.

[0069] It should be noted that the preset condition may refer to the automatic air conditioning adjustment condition corresponding to the air conditioning controller when the heat pump system startup condition is met, for example: when the indoor temperature is 30°C, the automatic air conditioning mode condition controls the heat pump system to work.

[0070] It is understandable that when the current temperature is not lower than the preset temperature, the working condition of the compressor is detected through the CAN bus, and when the compressor is in working condition, the operation of the compressor is cut off.

[0071] Furthermore, the step S202 includes: when controlling the heat pump system to work according to preset conditions, controlling the heat pump system to perform heat pump function detection according to a preset program, obtaining the internal temperature of the air-conditioning box and the duration of time when the internal temperature of the air-conditioning box reaches the preset air-conditioning box temperature; determining the function detection result according to the internal temperature of the air-conditioning box and the duration.

[0072] It should be noted that the internal temperature of the air conditioner box refers to the temperature inside the air conditioner box detected by the air conditioner box temperature sensor when the heat pump system performs the heating function according to the preset program and the instrument panel outlet discharges warm air. The preset air conditioner box temperature can be a pre-set temperature used to determine the temperature reached inside the air conditioner box when the heat pump system is working normally.

[0073] It is understandable that the duration may refer to the minimum duration of operation when the heat pump system operates normally.

[0074] In the specific implementation, when the air-conditioning controller controls the heat pump system to work according to the condition of "indoor temperature 30℃, automatic air-conditioning mode", the heat pump system performs the heating function according to the preset program, and detects the internal temperature of the air-conditioning box through the air-conditioning box temperature sensor. The heat pump function of the heat pump system is judged whether it is normal based on the internal temperature of the air-conditioning box and the duration when the internal temperature of the air-conditioning box reaches the preset air-conditioning box temperature, and the heat pump function detection result is determined based on the judgment result.

[0075] In this embodiment, step S30 includes:

[0076] Step S301: When the internal temperature of the air-conditioning box is lower than the preset temperature or the duration corresponding to the internal temperature of the air-conditioning box reaching the preset air-conditioning box temperature is shorter than the preset duration, determine that the heat pump system is faulty and obtain fault information of the components related to the heat pump function.

[0077] Step S302: Send the fault information to the central control screen via the CAN network for display.

[0078] It should be noted that when the heat pump system is unable to perform the heating function according to the preset program, it obtains the fault information of the components related to the heat pump function, and sends the fault information to the central control screen through the CAN network for display. The central control screen displays "Heat pump function is abnormal, please read the fault code", so that maintenance personnel can repair the vehicle according to the fault code.

[0079] This embodiment obtains the current ambient temperature upon receiving a heat pump function detection start instruction; determines the corresponding working mode of the air-conditioning controller according to the current ambient temperature and the preset temperature; controls the heat pump system to perform the heat pump function detection according to a preset program according to the working mode to obtain a function detection result; determines that the heat pump system is faulty and obtains fault information of components related to the heat pump function when the internal temperature of the air-conditioning box is lower than the preset temperature or the duration corresponding to the internal temperature of the air-conditioning box reaching the preset temperature is lower than the preset duration; sends the fault information to the central control screen for display via the CAN network. Compared with the prior art, which cannot avoid the influence of temperature on the realization of the heat pump function, resulting in the inability to complete the inspection of the whole vehicle function and low productivity, this embodiment avoids the influence of temperature on the realization of the function through a control method, completes the inspection of the whole vehicle function, and improves production efficiency and vehicle reliability.

[0080] Based on the above Figure 2 The first embodiment shown provides a third embodiment of the heat pump function detection method of the present invention.

[0081] In this embodiment, step S20 includes: when the compressor is cut off, controlling the heat pump system to detect components related to the heat pump function according to a preset program, and obtaining the detection results through the CAN network and the LIN network.

[0082] It should be noted that when the compressor is cut off, the air conditioning controller controls the heat pump system to detect the components related to the heat pump function according to the preset program. The components related to the heat pump independently operate and self-check, and return the self-check status through the CAN network and LIN network.

[0083] In this embodiment, the step S30 includes: determining an abnormal component signal in the heat pump function-related component according to the function detection result, determining fault information according to a fault code corresponding to the abnormal component signal, and sending the fault information to the central control screen for display via the CAN network.

[0084] It should be noted that the air-conditioning controller receives self-test information from components independently related to the heat pump. When the components return abnormal signals, the air-conditioning controller sends fault codes to the CAN network, and the central control screen displays "Heat pump function is abnormal, please read the fault code."

[0085] In the specific implementation, refer to Figure 4 System workflow diagram, the vehicle is in the starting state, press the "double flash" signal light, and then press the "HEAT" button of the air conditioning controller for more than 5S to enter the heat pump self-test function. The central control displays "Perform heat pump function test". Please click Confirm / Exit. When you click Exit, the heat pump function test will exit and the original operation interface will be restored. When you click Confirm, the heat pump function test will start, and the central control screen will display "Start heat pump function test". When the current ambient temperature is less than the preset temperature (such as: 20℃), the air conditioning controller controls the heat pump system to work according to the "indoor temperature 30℃, automatic air conditioning mode" condition. The heat pump system performs functions according to the established program, and warm air is discharged from the instrument panel outlet. The heat pump function test is completed when the air conditioning box temperature sensor detects that the internal temperature of the air conditioning box reaches 50℃ for 20S, and exits the program. The central control screen displays "The heat pump function is normal, and the test is completed". If the heat pump system cannot perform functions according to the established program, the controller sends a fault code to the CAN network, and the central control screen displays "The heat pump function is abnormal, please read the fault code";

[0086] When the current ambient temperature is ≥ the preset temperature (such as: 20℃), the working condition of the compressor is detected through the CAN bus. When the compressor is working, the air-conditioning controller cuts off the operation of the compressor, and controls the independent related components of the heat pump function to perform self-inspection through the preset program. The components of the heat pump independently related to the components are self-operated and self-inspected, and the self-inspection status is returned through the CAN network and the LIN network. The air-conditioning controller receives the self-inspection information of the heat pump independently related components. When the component returns an abnormal signal, the air-conditioning controller sends a fault code to the CAN network, and the central control screen displays "Heat pump function is abnormal, please read the fault code". If each component returns a normal working signal, the central control screen displays "Heat pump function is normal, detection completed".

[0087] This embodiment obtains the current ambient temperature upon receiving a heat pump function detection start instruction; determines the working mode corresponding to the air-conditioning controller according to the current ambient temperature and a preset temperature; controls the heat pump system according to the working mode to perform the heat pump function detection according to a preset program to obtain a function detection result; determines an abnormal component signal in the heat pump function-related components according to the function detection result; determines fault information according to a fault code corresponding to the abnormal component signal, and sends the fault information to the central control screen through the CAN network for display. Compared with the prior art, which cannot avoid the influence of temperature on the realization of the heat pump function, resulting in the inability to complete the inspection of the whole vehicle function and low productivity, this embodiment avoids the influence of temperature on the realization of the function through a control method, completes the inspection of the whole vehicle function, and improves production efficiency and vehicle reliability.

[0088] In addition, to achieve the above-mentioned purpose, the present invention also proposes a storage medium, on which a heat pump function detection program is stored, and when the heat pump function detection program is executed by a processor, the steps of the heat pump function detection method described above are implemented.
