[0003] During the use of related vehicle-mounted refrigerators, since the power consumption of vehicle-mounted refrigerators is large, it is very easy to deplete the power of the vehicle battery during operation.

[0004] Specifically, when the vehicle is powered off, the vehicle-mounted refrigerator continues to operate and continuously consumes power. Since there is no one to watch the vehicle at this time, that is, the vehicle-mounted refrigerator operates continuously without being controlled, the power of the vehicle battery will be continuously consumed by the vehicle-mounted refrigerator until the vehicle battery runs out of power.

[0005] However, not only when the vehicle is powered off, but also when the vehicle is powered on and started, especially for electric vehicles, the vehicle-mounted refrigerator operates continuously unconditionally, or is only turned on or off by the user based on experience, which is also extremely likely to cause the power of the vehicle battery to be depleted.

[0006] Therefore, in the control methods of related vehicle-mounted refrigerators, it is not possible to effectively and reasonably control the vehicle-mounted refrigerator in combination with different states of the vehicle and the battery power.

[0007] Based on this, there is a need for a solution that can comprehensively consider different states of the vehicle and combine the battery power to intelligently and reasonably control the vehicle-mounted refrigerator. Summary of the Invention

[0061] To make the objectives, technical solutions, and advantages of the present application clearer, the following further describes the present application in detail with reference to specific embodiments and the accompanying drawings.

[0062] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the ordinary meanings understood by those of ordinary skill in the art to which the present application pertains. In the embodiments of the present application, the terms "first", "second" and similar words do not denote any order, quantity or importance, but are only used to distinguish different components. Words such as "including" or "comprising" mean that the elements or objects appearing before this word cover the elements or objects listed after this word and their equivalents, without excluding other elements or objects. Words such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Upper", "lower", "left", "right", etc. are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0063] As described in the background art section, the related in-vehicle refrigerator control methods are still difficult to meet the actual usage needs.

[0064] The applicant found during the implementation of the present application that the main problem with the related in-vehicle refrigerator control methods is that: during the use of the related in-vehicle refrigerator, since the in-vehicle refrigerator consumes a large amount of power, it is very easy to deplete the power of the vehicle battery when working.

[0065] Specifically, when the vehicle is powered off, the in-vehicle refrigerator continues to work and continuously consumes power. Since there is no one watching the vehicle at this time, that is, the in-vehicle refrigerator continues to work without being controlled, the power of the vehicle battery will be continuously consumed by the in-vehicle refrigerator until the vehicle battery runs out of power.

[0066] However, not only when the vehicle is powered off, but also when the vehicle is powered on and started, especially for electric vehicles, the in-vehicle refrigerator works continuously unconditionally, or only relies on the user's experience to turn on or off the in-vehicle refrigerator, which is also extremely likely to cause the power of the vehicle battery to be depleted.

[0067] Therefore, in the related in-vehicle refrigerator control methods, it is not possible to effectively and reasonably control the in-vehicle refrigerator in combination with the different states of the vehicle and the battery power.

[0068] Based on this, the embodiments of the present application provide an in-vehicle refrigerator control method, which will be described in detail below in conjunction with the accompanying drawings.

[0069] Refer to Figure 1 , the in-vehicle refrigerator control method according to an embodiment of the present application includes the following steps:

[0070] Step S101, respectively determine the vehicle state and battery power of the vehicle.

[0071] In an embodiment of the present application, taking the control of an in-vehicle refrigerator of an electric vehicle as a specific example, as Figure 2 shown, in this electric vehicle, it specifically includes: an in-vehicle interaction screen (abbreviated as HU in the embodiments of the present application), a domain controller (abbreviated as XCU in the embodiments of the present application), a power battery, and an in-vehicle refrigerator (which can also be referred to as VFridge in the embodiments of the present application).

[0072] Among them, the power battery serves as the vehicle battery of the vehicle in this embodiment, and is specifically used to provide power for various electrical appliances and the driving of the electric vehicle; a delay switch can be displayed on the HU, and the delay switch is used to set the working duration of the in-vehicle refrigerator, which can also be referred to as the delay duration; the XCU in this embodiment is specifically used to control the HU and the in-vehicle refrigerator, and the XCU can also be used to obtain the vehicle state of the vehicle, the state of the in-vehicle refrigerator, the state of the delay switch, and the state of the power battery.

[0073] In this embodiment, the vehicle state of the vehicle can be specifically divided into power-off, power-on, and start. Among them, when the vehicle is powered off, when the in-vehicle refrigerator is not set to continue working, all other electrical appliances will be completely powered off, which can be regarded as the vehicle flameout state. In this embodiment, the vehicle state of the vehicle being powered off is represented as: local OFF; when the vehicle is powered on, all electrical appliances of the vehicle will be completely powered on. In this embodiment, the vehicle state of the vehicle being powered on is represented as: local ACC; in this embodiment, the vehicle state of the vehicle being started is represented as: local ON;

[0074] It can be seen that the three vehicle states of local OFF, local ACC, and local ON in this embodiment respectively correspond to three different positions that can be in after the car key is inserted into the key jack of the vehicle.

[0075] In this embodiment, the percentage of the currently available power of the vehicle battery (i.e., the power battery) in the vehicle battery capacity is used to represent the battery power, and the remaining battery power of the power battery is represented as SOC, that is, the displayed remaining battery power of this power battery; in some other embodiments, the specific remaining power of the battery at present, such as 20000 mAh, can also be used to represent the battery power.

[0076] As Figure 2 shown, the XCU can obtain the battery power of the power battery, and at the same time, the XCU can also obtain the vehicle state where the vehicle is currently located.

[0077] In this embodiment, the refrigerator can be in two states: on and off, and are respectively represented as: refrigerator = ON and refrigerator = OFF; further, the delay switch can also be in two states: on and off, and are respectively represented as: delay switch = ON and delay switch = OFF.

[0078] Based on this, the XCU can control the in-vehicle refrigerator and the delay switch of the in-vehicle refrigerator by further synthesizing the current battery power and vehicle state using the obtained current battery power and vehicle state.

[0079] It should be noted that the process of determining the vehicle state and battery power of the vehicle can be determined in real time, or at intervals (such as 1 second, 2 seconds, 5 seconds, etc.) or at specific time points.

[0080] Step S102: In response to determining that the battery power is less than or equal to the preset threshold power and the vehicle state is one of powered on or starting, control the in-vehicle refrigerator to close. In response to closing the in-vehicle refrigerator, close the delay switch set for the working duration of the in-vehicle refrigerator.

[0081] In the embodiment of the present application, based on the battery power and vehicle state determined in the above step S101, a threshold power can be calibrated for the power battery, and in combination with this threshold power, the in-vehicle refrigerator and the delay switch can be controlled.

[0082] In this embodiment, the threshold power can be calibrated to 20%. That is to say, if the current power of the power battery is 20% of the total capacity of the power battery, it is considered that the threshold power of the power battery is reached.

[0083] In some other embodiments, the threshold power can also be calibrated to other percentages according to specific situations.

[0084] Furthermore, based on the set threshold, the XCU can determine whether the power battery currently reaches the threshold power according to the obtained battery power.

[0085] Furthermore, when the XCU determines that the current SOC of the power battery is less than or equal to the threshold power, it controls the in-vehicle refrigerator to close, that is, controls the state of the in-vehicle refrigerator to refrigerator = OFF.

[0086] It can be seen that since the vehicle is in any one of the vehicle states of local ACC, local ON, and local OFF, when the SOC of the power battery is less than or equal to the threshold power, continuously using the in-vehicle refrigerator may exhaust the power of the power battery. Therefore, in this embodiment, when the vehicle is in any vehicle state and the XCU determines that the SOC is less than or equal to the threshold power, the in-vehicle refrigerator is controlled to refrigerator = OFF.

[0087] It can be seen that when the vehicle is in any vehicle state among local ACC, local ON, and local OFF, if the refrigerator = OFF, then the delay switch = OFF. That is to say, when the refrigerator = OFF, there is no need to condition the delay duration for it. Therefore, when the refrigerator = OFF, the delay switch = OFF, and the function of setting the delay duration is turned off.

[0088] It can be seen that based on the set threshold power, the in-vehicle refrigerator in any vehicle state can be controlled to stop working in time when the SOC of the power battery is insufficient, avoiding the depletion of the power of the power battery.

[0089] Step S103: In response to determining that the battery power is greater than the threshold power and determining that the vehicle state is one of powered on or started, keep the delay switch of the in-vehicle refrigerator open.

[0090] In the embodiment of the present application, based on the battery power determined in the above step S101, when the battery power is greater than the calibrated threshold power, the delay switch can be turned on according to the specific vehicle state, and the in-vehicle refrigerator can be made to work continuously.

[0091] Specifically, in this embodiment, when the XCU determines that the SOC is greater than the calibrated threshold power, it further determines the current vehicle state of the vehicle.

[0092] When the XCU determines that the vehicle is currently in any one of the vehicle states of local ACC or local ON, the XCU can control the delay switch to be delay switch = ON and set the specific delay duration through the delay switch.

[0093] In other embodiments, after the XCU determines that the vehicle is currently in any one of the vehicle states of local ACC or local ON, the state of the delay switch can also be kept as delay switch = OFF, that is, control the in-vehicle refrigerator not to work continuously.

[0094] It can be seen that the user of the in-vehicle refrigerator can control the in-vehicle refrigerator through the delay switch when the vehicle is in the state of local ACC or local ON and the SOC is greater than the threshold power, that is, the in-vehicle refrigerator can be continuously turned on.

[0095] Step S104: In response to determining that the delay switch is on, set the working duration for the in-vehicle refrigerator, turn on the in-vehicle refrigerator when the vehicle state becomes powered off, and control the in-vehicle refrigerator to be in one of the on state and the off state according to the timing process of the working duration.

[0096] In the embodiment of the present application, based on the above-mentioned turned-on delay switch, the user can further control the duration for which the in-vehicle refrigerator continues to work by setting the delay duration.

[0097] Specifically, when the vehicle state of the vehicle changes from the above-mentioned local ACC or local ON to local OFF, that is, after the vehicle shuts off, at this time, if the set delay switch that is turned on has not been turned off by the user or other factors, the in-vehicle refrigerator will continue to operate in the current local OFF state of the vehicle.

[0098] Meanwhile, after the XCU learns that the vehicle state is local OFF, it will start a timing process; wherein, this timing process is for the set delay duration, and when the timing process counts up to the set delay duration, the timing ends; for example, when the set delay duration is 3 hours, the timing process should time for 3 hours.

[0099] Further, during the timing process of the working duration, the XCU will detect the SOC of the power battery. If the SOC is always greater than the above-mentioned preset threshold power, the timing process will continue and control the in-vehicle refrigerator to continue operating.

[0100] After the timing process ends, the operation of the in-vehicle refrigerator will be stopped, that is, the state of the in-vehicle refrigerator will be controlled to refrigerator = OFF.

[0101] Further, according to the above steps, when the state of the in-vehicle refrigerator is refrigerator = OFF, the XCU will also simultaneously control the state of the delay switch to delay switch = OFF.

[0102] In some other embodiments, controlling the in-vehicle refrigerator to be in one of the on state and the off state according to the timing process of the working duration includes:

[0103] In response to determining that the battery power is less than or equal to the threshold power, control the in-vehicle refrigerator to turn off;

[0104] In response to turning off the in-vehicle refrigerator, turn off the delay switch.

[0105] In this embodiment, during the timing process of the working duration, the XCU will still detect the SOC of the power battery. If it is detected that the SOC is less than or equal to the above-mentioned preset threshold power, the XCU will terminate the timing process.

[0106] Further, when the timing process terminates, the XCU will further turn off the delay switch and control the state of the in-vehicle refrigerator to: refrigerator = OFF.

[0107] In another embodiment of the present application, controlling the in-vehicle refrigerator to be in one of the on state and the off state according to the timing process of the working duration further includes:

[0108] In response to determining that the vehicle state changes from power-off to start, turn off the delay switch.

[0109] In this embodiment, based on the above timing process, the XCU will obtain the vehicle state of the vehicle and perform different controls on the delay switch and the in-vehicle refrigerator according to the change of the current vehicle state of the vehicle.

[0110] Specifically, based on the timing process of the foregoing embodiment, it can be seen that this timing process is carried out based on the vehicle being in the local OFF state. When the XCU detects that the current vehicle state of the vehicle changes from local OFF to local ACC, it can be considered that the current vehicle has not yet started, and it can be considered that the current vehicle may still be in an unattended situation.

[0111] Therefore, when the vehicle state changes from local OFF to local ACC, the in-vehicle refrigerator and the delay switch are still controlled to remain in their original states unchanged.

[0112] Specifically, the XCU maintains the state of the delay switch as delay switch = ON and maintains the state of the in-vehicle refrigerator as refrigerator = ON.

[0113] In another embodiment of the present application, according to the timing process of the working duration, controlling the in-vehicle refrigerator to be in one of the on state and the off state further includes:

[0114] During the timing process of the working duration, in response to determining that the vehicle state changes from power-off to power-on, the delay switch is maintained in the on state;

[0115] In response to the delay switch being in the on state, the in-vehicle refrigerator is maintained in the on state.

[0116] In this embodiment, based on the above timing process, the XCU will obtain the vehicle state of the vehicle and perform different controls on the delay switch and the in-vehicle refrigerator according to the change of the current vehicle state of the vehicle.

[0117] Specifically, based on the timing process of the foregoing embodiment, it can be seen that this timing process is carried out based on the vehicle being in the local OFF state. When the XCU detects that the current vehicle state of the vehicle changes from local OFF to local ON, it can be considered that the vehicle has currently changed from the power-off state of the vehicle being turned off to the starting state. Therefore, it can be considered that the current vehicle already has relevant personnel to manage it. Therefore, the delay switch can be turned off and the in-vehicle refrigerator can be kept working.

[0118] Specifically, during the process of the XCU detecting the vehicle state, when the XCU determines that the vehicle state of the vehicle changes from local OFF to local ON, it controls the state of the delay switch to change from delay switch = ON to delay switch = OFF and controls the state of the in-vehicle refrigerator to remain refrigerator = ON.

[0119] In some other embodiments of the present application, such as Figure 2 shown, as a visual in-vehicle interaction screen, HU can not only interact with the users of the vehicle, but also interact with the XCU.

[0120] Specifically, the users of the in-vehicle refrigerator can perform user operations through HU. For example, they can set the delay duration, etc. When the delay switch = ON, HU displays the delay switch as a clickable state. When the delay switch = OFF, HU displays the delay switch as a non-clickable gray display or does not display it. Further, when the delay switch is in a clickable state, the function of setting the delay duration can be displayed on HU, and the user can further set the delay duration for the in-vehicle refrigerator on HU. When the delay switch = OFF, the function of setting the delay duration is displayed on HU, or the function of setting the delay duration is set to a gray display.

[0121] Further, XCU can also obtain the current state of the delay switch through HU and control the delay switch through HU.

[0122] Specifically, when the state of the delay switch is set to delay switch = ON or delay switch = OFF according to user operations, HU sends the current state of the delay switch and the related setting instructions of the delay duration to XCU.

[0123] Further, HU will also receive the control instructions for the switch delay and the delay duration feedback from XCU, and HU will control the display of the delay switch and the delay duration according to the control instructions.

[0124] In some other embodiments of the present application, after controlling the in-vehicle refrigerator to close, it further includes:

[0125] Determine the reason for closing the in-vehicle refrigerator according to the vehicle state and battery power when closing the in-vehicle refrigerator;

[0126] Visually display the reason.

[0127] In this embodiment, based on the visualization function of HU set in the foregoing embodiment, the reason for closing the in-vehicle refrigerator can be displayed to the users of the in-vehicle refrigerator.

[0128] Specifically, when the reason for closing the in-vehicle refrigerator is that XCU detects that the SOC of the power battery is less than or equal to the threshold power, HU determines the reason for closing the in-vehicle refrigerator as SOC too low; and closes the delay switch in this case.

[0129] Further, HU can display text such as: "The reason why the refrigerator cannot be opened = SOC too low".

[0130] In some embodiments, when the XCU detects that the delay switch = ON, and the vehicle status is local ACC or local ON, if the XCU detects that the operating status of the refrigerator is turned off without receiving any fault codes, it determines that the reason for the refrigerator to be turned off is that the user actively turns it off; and in this case, it turns off the delay switch.

[0131] Furthermore, the HU will be able to display text such as: "Reason for the refrigerator not being operable = The refrigerator is turned off".

[0132] In some embodiments, when the XCU detects that the delay switch = ON, and the vehicle status is local OFF and the power battery SOC is greater than the threshold power, if the XCU receives any refrigerator fault codes, or detects that the operating status of the refrigerator is turned off, it determines that the reason for the refrigerator to be turned off is that the on-vehicle refrigerator has a fault; and in this case, it turns off the delay switch.

[0133] Furthermore, the HU will be able to display text such as: "Reason for the refrigerator not being operable = Refrigerator fault".

[0134] In some embodiments, when the XCU detects that the delay switch = ON, and the vehicle status is local OFF and the power battery SOC is greater than the threshold power, if the XCU receives any other vehicle fault codes, or detects that the entire vehicle cannot be powered on with high voltage, it determines that the reason for the refrigerator to be turned off is that the entire vehicle has a fault; and in this case, it turns off the delay switch.

[0135] Furthermore, the HU will be able to display text such as: "Reason for the refrigerator not being operable = Entire vehicle fault".

[0136] It can be seen that the on-vehicle refrigerator control method according to the embodiments of the present application, based on the detection of the vehicle status and battery power, comprehensively considers different vehicle statuses of power-on, power-off, and startup to control the on-vehicle refrigerator, and in combination with the set threshold power, enables the on-vehicle refrigerator to be turned off immediately when the battery power is less than or equal to the threshold power, thus avoiding depleting the battery power due to the operation of the on-vehicle refrigerator.

[0137] Furthermore, through the delay switch turned on in the power-on or startup state, on the premise that the battery power is greater than the threshold power, after the vehicle is powered off, the on-vehicle refrigerator can continue to operate, and its operation can be controlled according to the set working duration, and specifically according to the situation during the timing process, the on-vehicle refrigerator is controlled to remain on or off.

[0138] In some other embodiments of the present application, after turning on the on-vehicle refrigerator when the vehicle status changes to power-off, it further includes:

[0139] Determine the current temperature inside the on-vehicle refrigerator and set a temperature threshold;

[0140] In response to determining that the current temperature is lower than the temperature threshold, control the vehicle-mounted refrigerator to turn off;

[0141] In response to determining that the current temperature is greater than or equal to the temperature threshold, control the vehicle-mounted refrigerator to remain on.

[0142] In this embodiment, by detecting the current temperature of the vehicle-mounted refrigerator, the vehicle-mounted refrigerator can be made to work intermittently, so as to achieve the purpose of both saving battery power and maintaining the temperature inside the vehicle-mounted refrigerator.

[0143] Specifically, the current temperature inside the vehicle-mounted refrigerator can be detected, and a temperature threshold for controlling the vehicle-mounted refrigerator to turn on or off can be set for it.

[0144] Furthermore, when the vehicle changes from local ON or local ACC to local OFF, and after the delay duration is enabled, the vehicle-mounted refrigerator can remain on when the battery power is greater than the threshold power.

[0145] Furthermore, in the state where the vehicle-mounted refrigerator remains on, based on the determined current temperature, the magnitude relationship between the current temperature and the temperature threshold is judged.

[0146] Furthermore, if it is detected that the current temperature is greater than or equal to the temperature threshold, the vehicle-mounted refrigerator is continuously kept in the on state; if it is detected that the current temperature is lower than the temperature threshold, the vehicle-mounted refrigerator is turned off.

[0147] Furthermore, after the vehicle-mounted refrigerator is turned off, the current temperature can continue to be detected, and the above process is repeatedly executed.

[0148] It should be noted that the process of determining the current temperature can be real-time determination, or can be determined at intervals of a period of time (such as 1 second, 2 seconds, 5 seconds, etc.) or at specific time points.

[0149] In some other embodiments of the present application, the determination of the battery power may further include:

[0150] Set a storage battery that provides power for the vehicle-mounted refrigerator;

[0151] Use the power battery available in the vehicle to supply power to the storage battery;

[0152] And determine the remaining power of the storage battery;

[0153] Take the remaining power of the storage battery as the battery power.

[0154] In this embodiment, use the power battery of the vehicle to supply power to the storage battery of the vehicle-mounted refrigerator, and take the determined current remaining power of the storage battery as the battery power.

[0155] Specifically, the battery power is represented by the percentage of the currently available power of the storage battery in the battery capacity, and the remaining battery power of the storage battery is represented as SOC, that is, the remaining battery power shown on the display of the storage battery; in some other embodiments, the specific remaining power of the storage battery at present, for example, 20000 mAh, can also be used to represent the battery power.

[0156] Furthermore, the battery power of the storage battery can be obtained through the XCU.

[0157] In some other embodiments, using the power battery equipped in the vehicle to supply power to the storage battery includes:

[0158] Setting a power supply threshold for the power battery;

[0159] Determining the remaining power of the power battery;

[0160] In response to determining that the remaining power of the power battery is greater than the power supply threshold, making the power battery continuously supply power to the storage battery;

[0161] In response to determining that the remaining power of the power battery is less than or equal to the power supply threshold, making the power battery stop supplying power to the storage battery.

[0162] In this embodiment, when using the power battery to supply power to the storage battery, in order to avoid the depletion of the power of the power battery, a power supply threshold can be set for the power battery, and the remaining power of the power battery can be detected.

[0163] Furthermore, when the remaining power of the power battery is greater than the power supply threshold, it is considered that the power of the power battery is sufficient and can continuously supply power to the storage battery; when the remaining power of the power battery is less than or equal to the power supply threshold, it is considered that the power of the power battery is insufficient and it is difficult to supply power to the storage battery, and the power battery is made to stop supplying power to the storage battery.

[0164] It can be seen that this method combines different vehicle states and battery power to control the in-vehicle refrigerator, so that the in-vehicle refrigerator can not only continue to be used after power-off, but also avoid the situation of depleting the battery power in various vehicle states.

[0165] It should be noted that the method of the embodiments of the present application can be executed by a single device, such as a computer or a server, etc. The method of this embodiment can also be applied to a distributed scenario and completed by multiple devices cooperating with each other.
