[0053] The following is a detailed description of the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0054] The embodiment of the present application provides a method for setting the temperature of a vehicle refrigerator, which is applied to a refrigerator controller 101 of a vehicle refrigerator. Figure 1 As shown, the vehicle refrigerator further includes an item category collection module 102 disposed in the vehicle refrigerator and an ambient temperature sensor 103 disposed outside the vehicle refrigerator, and the item category collection module 102 and the ambient temperature sensor 103 are electrically connected to the refrigerator controller 101 respectively. The refrigerator controller 101 of the vehicle refrigerator is also connected to the cloud server 105 via the wireless communication module 104. The method provided in the embodiment of the present application includes:

[0055] S201: receiving the item information for representing the item category collected by the item category collection module 102 .

[0056] S202: Determine the category of the items in the vehicle refrigerator according to the item information.

[0057] For example, the specific implementation of S201-S202 includes but is not limited to the following two methods:

[0058] In some embodiments, the item category acquisition module 102 is a label scanner, and the item information is the label information (such as a barcode) on the item packaging bag of the item. The refrigerator controller 101 of the vehicle refrigerator can receive the label information on the item packaging bag of the item in the vehicle refrigerator scanned by the label scanner; and extract the item category of the item from the label information. It can be understood that the label information includes the item category, price, production date, shelf life, and weight information of the item, so the item category of the item can be obtained by scanning the label information.

[0059] In other embodiments, the item category acquisition module 102 is a camera, and the item information is an item image. The refrigerator controller 101 of the vehicle refrigerator can receive the item image of the item in the vehicle refrigerator acquired by the camera, perform image recognition on the item image, and obtain the item category of the item in the vehicle refrigerator.

[0060] For example, the item category of the items in the vehicle refrigerator can be identified based on a pre-trained item category recognition model, wherein the item category recognition model is trained based on a plurality of training samples, each training sample including an item image and a corresponding item category.

[0061] S203: When the items of the item category are determined to be placed in the vehicle refrigerator, the current ambient temperature collected by the ambient temperature sensor 103 is received, and historical first temperature setting samples corresponding to items of multiple item categories associated with other vehicle users are obtained from the cloud server 105 .

[0062] Each historical first temperature setting sample includes a historical actual freezing temperature set by other vehicle users for items of the item category under a historical ambient temperature.

[0063] In some implementations, samples of historical first temperatures corresponding to items of multiple item categories associated with other vehicle users may be set to perform data deduplication, remove outliers, or normalize to improve data reliability.

[0064] S204: Input the current ambient temperature and historical first temperature setting samples corresponding to items of multiple item categories associated with other vehicle users into a pre-trained freezing temperature determination model to determine a recommended freezing temperature for the vehicle refrigerator.

[0065] The freezing temperature determination model is obtained based on multiple training samples. Each training sample includes multiple historical current ambient temperatures, historical first temperature setting samples of items of item categories associated with other vehicle users, and historical actual freezing temperatures set by other vehicle users for vehicle refrigerators. In this way, the recommended freezing temperature of the vehicle refrigerator can be determined to meet the public's freezing needs for items of this item category. In this way, the reliability of the determined recommended freezing temperature meeting the freezing needs of the vehicle user for items of this item category is high.

[0066] For example, if the ambient temperature is 35 degrees Celsius and the item category is watermelon, the recommended freezing temperature may be 3 degrees Celsius; for another example, if the ambient temperature is 25 degrees Celsius and the item category is watermelon, the recommended freezing temperature may be 10 degrees Celsius.

[0067] In the case of determining the items of an item category to be placed in the vehicle refrigerator, the method provided by the embodiment of the present application may also include: obtaining historical second temperature setting samples corresponding to items of multiple item categories associated with the vehicle user and stored locally. Each historical second temperature setting sample includes the historical actual freezing temperature set by the vehicle user for the items of the item category at a historical ambient temperature; then each training sample also includes: historical second temperature setting samples of items of the item category historically associated with the vehicle user. Since each training sample also includes: historical second temperature setting samples of items of the item category historically associated with the vehicle user, the reliability of the recommended freezing temperature determined by the freezing temperature determination model can be higher.

[0068] S205: Control the operating temperature of the vehicle refrigerator to the recommended freezing temperature.

[0069] In summary, the embodiment of the present application provides a method for setting the temperature of a vehicle refrigerator, which can determine the item category of the items in the vehicle refrigerator according to the collected item information; when the items of the item category are determined to be placed in the vehicle refrigerator, the current ambient temperature collected by the ambient temperature sensor 103 is received, and the historical first temperature setting samples corresponding to the items of multiple item categories associated with other vehicle users are obtained from the cloud server 105. Then, the current ambient temperature and the historical first temperature setting samples corresponding to the items of multiple item categories associated with other vehicle users are input into the pre-trained freezing temperature determination model to determine the recommended freezing temperature of the vehicle refrigerator. Since the freezing temperature determination model is obtained based on multiple training samples, each training sample includes multiple historical current ambient temperatures, the historical first temperature setting samples of the items of the item categories associated with other vehicle users, and the historical actual freezing temperatures set by other vehicle users for the vehicle refrigerator. In this way, the determined recommended freezing temperature of the vehicle refrigerator meets the freezing temperature preference of the vehicle user for the items in the vehicle refrigerator, the user experience is high, and the working temperature of the vehicle refrigerator can be automatically set without manual operation, which further improves the user experience.

[0070] In addition, if Figure 3 As shown, after S206, the method provided in the embodiment of the present application may further include:

[0071] S301: Transmitting the recommended freezing temperature to the vehicle terminal for display.

[0072] S302: Receive the actual freezing temperature set by the user for the vehicle refrigerator.

[0073] S303: Control the operating temperature of the vehicle refrigerator to switch from the recommended freezing temperature to the actual freezing temperature.

[0074] Based on the above S301-S303, the user can switch the recommended freezing temperature to an actual freezing temperature that better meets personal needs, with high reliability.

[0075] In addition, if Figure 4 As shown, after S303, the method provided in the embodiment of the present application may further include:

[0076] S401: Determine the temperature difference between the actual freezing temperature and the recommended freezing temperature.

[0077] S402: When the temperature difference is greater than a set temperature threshold, the network parameters of the freezing temperature determination model are optimized according to the temperature difference.

[0078] In this way, the network parameters of the freezing temperature determination model can be continuously optimized, so that the recommended freezing temperature output by the subsequent freezing temperature determination model is more in line with user needs.
