[0030] Embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and embodiments of the present application are described in detail below.

[0031] At present, the vehicle-mounted refrigerator can only provide basic refrigeration or heat preservation functions, and lacks various scene control of the vehicle-mounted refrigerator and other vehicle-mounted systems of the vehicle, for example, lacks linkage control of the vehicle-mounted refrigerator and the vehicle-mounted air conditioner, resulting in low intelligence of the vehicle-mounted refrigerator.

[0032] Therefore, the vehicle refrigerator control method of this invention, when detecting an object inside the vehicle refrigerator, associates the vehicle refrigerator with the operating status of the vehicle air conditioner, and controls the vehicle refrigerator to operate in cooling or heating mode according to the cooling or heating mode of the vehicle air conditioner, thereby realizing intelligent linkage between the vehicle refrigerator and the vehicle air conditioner, increasing the multi-scenario control of the vehicle refrigerator, and improving the intelligence of the vehicle refrigerator.

[0033] Vehicle-mounted refrigerators use semiconductor electronic chips or compressors for heating or cooling, while self-installed refrigerators use signal converters for heating or cooling. The following example illustrates this using a vehicle-mounted refrigerator as an example.

[0034] The following is combined Figures 1-4 An example of the control method for a vehicle-mounted refrigerator according to an embodiment of the present invention will be provided.

[0035] like Figure 1 As shown, the control method for a vehicle-mounted refrigerator in this embodiment of the invention includes at least steps S1 and S2.

[0036] Step S1: When the pressure inside the vehicle refrigerator reaches the preset pressure threshold and the vehicle air conditioner is turned on, determine the operating status of the vehicle air conditioner.

[0037] The preset pressure threshold can be set by the user. When the pressure inside the car refrigerator reaches the preset pressure threshold, it is assumed that there is an object inside the car refrigerator. At this time, the operating status of the car refrigerator and the car air conditioner can be linked and controlled.

[0038] In this embodiment, a pressure sensor is mounted on the bottom of the vehicle refrigerator to monitor the pressure value inside the vehicle refrigerator in real time. When an object is placed inside the vehicle refrigerator, the pressure sensor will receive a pressure signal and determine the relationship between the pressure value inside the vehicle refrigerator and a preset pressure threshold. If the pressure value inside the vehicle refrigerator is less than the preset pressure threshold, it is assumed that there is no object inside the vehicle refrigerator, and the vehicle refrigerator is not associated with the operating status of the vehicle air conditioner.

[0039] If the pressure inside the car refrigerator is greater than or equal to a preset pressure threshold, it is assumed that there is an object inside the car refrigerator. Then, it continues to determine whether the car air conditioner is turned on. If the car air conditioner is turned on, its operating status is determined, such as whether the car air conditioner is in cooling or heating mode. Based on the cooling or heating status of the car air conditioner, the car refrigerator is controlled to operate in cooling or heating mode. If the car air conditioner is not turned on, the car refrigerator does not work.

[0040] The following is for reference. Figure 2 An example is provided to illustrate the working method of the vehicle-mounted refrigerator according to an embodiment of the present invention.

[0041] like Figure 2As shown, the working method of the vehicle-mounted refrigerator in the embodiment of the application comprises at least steps S11-S15.

[0042] Step S11, start.

[0043] Step S12, judge whether the pressure value in the vehicle-mounted refrigerator reaches a preset pressure threshold value, if yes, execute step S14; if no, execute step S13.

[0044] Step S13, the vehicle-mounted refrigerator does not work.

[0045] Step S14, judge whether the vehicle-mounted air conditioner is turned on, if yes, execute step S15; if no, execute step S12.

[0046] Step S15, determine the running state of the vehicle-mounted air conditioner.

[0047] It can be understood that when the pressure value in the vehicle-mounted refrigerator reaches the preset pressure threshold value, if it is determined that the vehicle-mounted air conditioner is turned on, the running state of the vehicle-mounted air conditioner is acquired so as to control the running of the vehicle-mounted refrigerator according to the running state of the vehicle-mounted air conditioner.

[0048] Step S2, control the refrigeration running or the heating running of the vehicle-mounted refrigerator according to the running state of the vehicle-mounted air conditioner.

[0049] In the embodiment, after the running state of the vehicle-mounted air conditioner is determined, the running state of the vehicle-mounted refrigerator is automatically controlled according to the running state of the vehicle-mounted air conditioner, when the vehicle-mounted air conditioner is in the refrigeration state, the vehicle-mounted refrigerator is correspondingly controlled to run in the refrigeration mode; when the vehicle-mounted air conditioner is in the heating state, the vehicle-mounted refrigerator is correspondingly controlled to run in the heating mode, thereby associating the vehicle-mounted refrigerator with the vehicle-mounted air conditioner, realizing the intelligent control of the vehicle-mounted air conditioner on the vehicle-mounted refrigerator, and improving the utilization rate of the vehicle-mounted refrigerator.

[0050] According to the control method of the vehicle-mounted refrigerator in the embodiment of the application, the pressure sensor is carried on the bottom of the vehicle-mounted refrigerator to detect the pressure value in the vehicle-mounted refrigerator, when the pressure value in the vehicle-mounted refrigerator reaches the preset pressure threshold value, it is considered that there is an object in the vehicle-mounted refrigerator, at this time, in order to increase the intelligent control of the vehicle-mounted refrigerator, the running state of the vehicle-mounted refrigerator is associated with the running state of the vehicle-mounted air conditioner, for example, whether the vehicle-mounted air conditioner is turned on is judged, when the vehicle-mounted air conditioner is turned on, the refrigeration running of the vehicle-mounted refrigerator is controlled according to the refrigeration state of the vehicle-mounted air conditioner, or the heating running of the vehicle-mounted refrigerator is controlled according to the heating state of the vehicle-mounted air conditioner, by associating and controlling the running state of the vehicle-mounted refrigerator with the running state of the vehicle-mounted air conditioner, the refrigeration or heating running of the vehicle-mounted refrigerator changes with the running state of the vehicle-mounted air conditioner, realizing the intelligent linkage of the vehicle-mounted refrigerator with other vehicle-mounted systems of the vehicle, increasing the various scene control of the vehicle-mounted refrigerator, and thereby improving the utilization rate of the vehicle-mounted refrigerator.

[0051] In some embodiments, controlling the refrigeration operation or the heating operation of the vehicle-mounted refrigerator according to the operating state of the vehicle-mounted air conditioner comprises: when the vehicle-mounted air conditioner is in the refrigeration operation, adjusting the vehicle-mounted refrigerator from the current temperature to a first preset temperature, and controlling the vehicle-mounted refrigerator to decrease from the first preset temperature to a second preset temperature within a first preset time, wherein the second preset temperature is less than the first preset temperature; when the vehicle-mounted air conditioner is in the heating operation, adjusting the vehicle-mounted refrigerator from the current temperature to a third preset temperature, and controlling the vehicle-mounted refrigerator to increase from the third preset temperature to a fourth preset temperature, wherein the third preset temperature is greater than the first preset temperature, and the fourth preset temperature is greater than the third preset temperature.

[0052] In an embodiment, after the vehicle-mounted air conditioner is turned on, the display screen displays that the default temperature of the air conditioner is LO, at this time, the default temperature of the vehicle-mounted refrigerator is 0℃, the vehicle-mounted air conditioner takes LO as the boundary, and the vehicle-mounted refrigerator takes 0℃ as the boundary.

[0053] When the vehicle-mounted air conditioner is in the refrigeration operation, the vehicle-mounted refrigerator is first adjusted from the current temperature to a first preset temperature, and the vehicle-mounted refrigerator is controlled to decrease from the first preset temperature to a second preset temperature within a first preset time, for example, the first preset temperature is 0℃, the first preset time is 3 minutes, the vehicle-mounted refrigerator is first adjusted from the current temperature to the first preset temperature 0℃, and the vehicle-mounted refrigerator is controlled to decrease linearly from the first preset temperature 0℃ within the first preset time 3 minutes until the second preset temperature is reached, wherein the second preset temperature is less than the first preset temperature, the second preset temperature is the lowest temperature value that the vehicle-mounted refrigerator can reach, and the first preset time can be set by the user. By setting the vehicle-mounted refrigerator to change according to a smooth curve when the temperature changes, it is prevented that a large temperature difference causes a large amount of water to be generated in the vehicle-mounted refrigerator or the vehicle-mounted refrigerator to be burned out.

[0054] When the vehicle-mounted air conditioner is in the heating operation, the vehicle-mounted refrigerator is first adjusted from the current temperature to a third preset temperature, and the vehicle-mounted refrigerator is controlled to increase from the third preset temperature to a fourth preset temperature, for example, the third preset temperature is 26℃, the fourth preset temperature is 60℃, the vehicle-mounted refrigerator is first adjusted from the current temperature to the third preset temperature 26℃, and the vehicle-mounted refrigerator is controlled to continue to increase from the third preset temperature 26℃ until the fourth preset temperature 60℃ is reached, wherein the third preset temperature is greater than the first preset temperature, and the fourth preset temperature is greater than the third preset temperature, and the fourth preset temperature is the highest temperature value that the vehicle-mounted refrigerator can reach.

[0055] In some embodiments, when the vehicle-mounted refrigerator is controlled to increase from the third preset temperature to the fourth preset temperature, a preset temperature interval from the third preset temperature to the fourth preset temperature is determined, and the vehicle-mounted refrigerator is controlled to increase from the third preset temperature to the fourth preset temperature according to the preset temperature interval.

[0056] In embodiments, when the vehicle air conditioner is in heating operation, a preset temperature interval corresponding to the vehicle refrigerator between the third preset temperature and the fourth preset temperature is determined. For example, there are 30 preset temperature intervals between the L0 temperature and the highest temperature HI of the vehicle air conditioner in the heating state, and the vehicle refrigerator is divided into 30 preset temperature intervals between the third preset temperature 26°C (corresponding to the L0 temperature of the vehicle air conditioner) and the fourth preset temperature 60°C (corresponding to the HI temperature of the vehicle air conditioner). The vehicle refrigerator is controlled to change linearly and smoothly from the third preset temperature 26°C to the fourth preset temperature 60°C according to the 30 preset temperature intervals.

[0057] It should be noted that if the vehicle air conditioner also changes according to the smooth curve when the temperature changes, the vehicle refrigerator and the vehicle air conditioner can be selected to change consistently.

[0058] In some embodiments, before determining the operating state of the vehicle air conditioner, it is detected that the outside temperature is greater than or equal to a refrigeration temperature threshold, and it is determined that the vehicle air conditioner is in refrigeration operation. It is detected that the outside temperature is less than or equal to a heating temperature threshold, and it is determined that the vehicle air conditioner is in heating operation.

[0059] In embodiments, after the whole vehicle is powered on and the engine is ignited, the weather and temperature signals are received. When it is detected that the outside temperature is greater than or equal to a refrigeration temperature threshold, for example, ≥25°C, it is considered that the outside temperature is high, and it is determined that the vehicle air conditioner is in refrigeration operation. When the vehicle air conditioner is in refrigeration operation, the operating state of the vehicle air conditioner is associated with the operating state of the vehicle refrigerator, so that the operating state of the vehicle refrigerator runs with the operating state of the vehicle air conditioner.

[0060] When it is detected that the outside temperature is less than or equal to a heating temperature threshold, for example, ≤5°C, it is considered that the outside temperature is low, and it is determined that the vehicle air conditioner is in heating operation. When the vehicle air conditioner is in heating operation, the operating state of the vehicle air conditioner is associated with the operating state of the vehicle refrigerator, so that the operating state of the vehicle refrigerator runs with the operating state of the vehicle air conditioner.

[0061] In some embodiments, before determining the operating state of the vehicle air conditioner, it is detected that the refrigeration button of the vehicle air conditioner is triggered, and it is determined that the vehicle air conditioner is in refrigeration operation. It is detected that the refrigeration button of the vehicle air conditioner is not triggered, and it is determined that the vehicle air conditioner is in heating operation.

[0062] In embodiments, after the whole vehicle is powered on and the engine is ignited, if it is detected that the refrigeration button of the vehicle air conditioner is triggered, it is considered that the user needs to lower the temperature, and it is determined that the vehicle air conditioner is in refrigeration operation. If it is detected that the refrigeration button of the vehicle air conditioner is not triggered, it is considered that the user needs to raise the temperature, and it is determined that the vehicle air conditioner is in heating operation.

[0063] In some embodiments, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered and the cooling button is not detected to be triggered again within a first preset time. The vehicle refrigerator is controlled to be in heating operation.

[0064] In an embodiment, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered and the cooling button is not detected to be triggered again within a first preset time, for example, 3 minutes. It is considered that the user cancels the cooling operation of the vehicle air conditioner. The vehicle refrigerator is controlled to be in heating operation to meet the user's demand for temperature adjustment. The first preset time can be set by the user, for example, changed to 5 minutes, 30 seconds, etc.

[0065] In some embodiments, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered and the cooling button is not detected to be triggered again within a first preset time. The vehicle refrigerator is controlled to be in cooling operation.

[0066] In an embodiment, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered and the cooling button is not detected to be triggered again within a first preset time, for example, 3 minutes. It is considered that the user may have mistakenly triggered the cooling button. The vehicle refrigerator is controlled to keep cooling operation to prevent the internal temperature of the refrigerator from changing rapidly and causing the service life of the refrigerator to be reduced or even damaged. The second preset time can be set by the user, for example, changed to 5 minutes, 30 seconds, etc.

[0067] In some embodiments, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered and the cooling button is not detected to be triggered again within a first preset time. The vehicle refrigerator is controlled to be in cooling operation.

[0068] In an embodiment, after determining that the vehicle air conditioner is in cooling operation, the vehicle refrigerator is controlled to be in cooling operation. During the cooling operation of the vehicle refrigerator, it is detected that the cooling button of the vehicle air conditioner is triggered, and it is detected that the cooling button is triggered multiple times within a third preset time, for example, 3 minutes. The time when the cooling button is triggered last time within the third preset time, for example, 3 minutes, is counted. After the counting time reaches a fourth preset time, for example, 3 minutes, the vehicle refrigerator is controlled to be in cooling operation or heating operation according to the operating state of the vehicle air conditioner. That is, when the vehicle air conditioner is in cooling state, the vehicle refrigerator is controlled to be in cooling operation; when the vehicle air conditioner is in heating state, the vehicle refrigerator is controlled to be in heating operation. The third preset time can be set by the user, for example, changed to 5 minutes, 30 seconds, etc.

[0069] In some embodiments, when the vehicle refrigerator is a self-provided vehicle refrigerator, a power module and a signal conversion module are arranged between the vehicle air conditioner and the self-provided vehicle refrigerator.

[0070] In an embodiment, as shown in FIG. 8, it is a schematic diagram of a working method of a self-provided vehicle refrigerator according to an embodiment of the present application. By arranging a power module and a signal conversion module between the vehicle air conditioner and the self-provided vehicle refrigerator, signal conversion is facilitated when the self-provided vehicle refrigerator and the vehicle air conditioner are linked and controlled. Figure 3

[0071] For example, when the power module is turned on to supply power to the self-provided vehicle refrigerator, the signal conversion module receives the cooling signal of the vehicle air conditioner, converts the cooling signal, obtains the recognizable cooling signal of the self-provided vehicle refrigerator, and controls the self-provided refrigerator to be in cooling operation according to the recognizable cooling signal of the self-provided vehicle refrigerator. When the power module is turned on to supply power to the self-provided vehicle refrigerator, the signal conversion module receives the heating signal of the vehicle air conditioner, converts the heating signal, obtains the recognizable heating signal of the self-provided vehicle refrigerator, and controls the self-provided refrigerator to be in heating operation according to the recognizable heating signal of the self-provided vehicle refrigerator.

[0072] ​Specifically, the signals corresponding to refrigeration or heating of the self-provided vehicle refrigerator are different, if the signal sent by the self-provided vehicle refrigerator when refrigerating is 1, then the signal sent by the self-provided vehicle refrigerator when heating can be 0, a power module and a signal switching module are arranged between the vehicle air conditioner and the self-provided vehicle refrigerator, when the power module supplies power to the vehicle refrigerator, the refrigeration key of the self-provided vehicle refrigerator is pressed, and the electric signal is sent to the host through the signal switching module, and the host stores the signal (the same for the heat preservation key), for example, the host stores the refrigeration signal as A and the heating signal as B after receiving the refrigeration signal and the heating signal, the host compares the stored signal with the refrigeration signal C and the heating signal D sent by the vehicle air conditioner, when the vehicle air conditioner sends the refrigeration signal C, the signal converter receives the refrigeration signal C of the vehicle air conditioner, converts the refrigeration signal C, obtains the refrigeration signal A recognizable by the self-provided vehicle refrigerator, and sends the refrigeration signal A to the self-provided vehicle refrigerator to control the self-provided vehicle refrigerator to refrigerate; when the vehicle air conditioner sends the heating signal D, the signal converter receives the heating signal D of the vehicle air conditioner, converts the heating signal D, obtains the heating signal B recognizable by the self-provided vehicle refrigerator, and sends the heating signal B to the self-provided vehicle refrigerator to control the self-provided vehicle refrigerator to heat, so that the intelligent control of the vehicle air conditioner on the vehicle refrigerator is realized.

[0073] It can be understood that the above method can be applied to vehicle refrigerators and other vehicle products with refrigeration or heating functions, such as vehicle cup holders.

[0074] In the embodiment of the application, the vehicle air conditioner which is the master control party for controlling the refrigeration or heating of the vehicle refrigerator can be replaced by any vehicle system device in the vehicle which has signal changes leading to different results, for example, the vehicle refrigerator is controlled to refrigerate or heat according to the temperature of the seat.

[0075] Or provide personalized settings based on the emotion recognition technology of the A-pillar camera in the vehicle. There are eight common human emotions: calm, anger, disgust, sadness, joy, romance, happiness and fear. Set calm, joy, romance and happiness as positive emotions, set anger, disgust, sadness and fear as negative emotions, and set other emotions as other emotions. The above-mentioned emotions can be recognized by the camera. In order to achieve the effect of personalization, a user self-selection matching function can be set, for example, when the set is negative emotion, the vehicle refrigerator is refrigerated, but the user wants to set the vehicle refrigerator to heat, a matching button can be set on the central control screen for self-selection.

[0076] When it is detected that the user continuously shows positive emotions within a preset time and the vehicle refrigerator recognizes that there is stress, the vehicle refrigerator actively heats; when it is detected that the user continuously shows negative emotions or other emotions within a preset time and the vehicle refrigerator recognizes that there is stress, the vehicle refrigerator actively cools.

[0077] Alternatively, for female users, the car refrigerator can be linked to their menstrual cycle. For example, a menstrual cycle monitoring app can be integrated into the central control display screen. One day before the period is due, the central control display screen will display a reminder about the schedule. Within a week of the reminder popping up, the car refrigerator will start heating.

[0078] Alternatively, a detector and temperature sensor can be installed at the bottom of the car refrigerator to store information about popsicles or ice in the main unit in advance. When an object is detected, it can be compared with the database to determine whether the object placed in the car refrigerator is a popsicle or ice. If a popsicle or ice is detected, the car refrigerator will continue to cool even if the car air conditioner is in heating mode.

[0079] The following is for reference. Figure 4 An example of the control method for a vehicle-mounted refrigerator according to an embodiment of the present invention will be provided.

[0083] Step S23: The car refrigerator is not working.

[0084] Step S24: Determine whether the detected outside temperature is greater than or equal to the cooling temperature threshold. If yes, proceed to step S29; otherwise, proceed to step S27.
