[0048] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0049] In the related art, the cooling of new loads added to a car refrigerator is usually slow. How to quickly cool the load to meet customer needs is the core of the car refrigerator user experience.

[0050] FIG1 is a flow chart of a control method for a vehicle refrigerator provided by an exemplary embodiment. As shown in FIG1 , the method includes the following steps:

[0051] In step S101 , when a new load is added to the vehicle refrigerator, the vehicle refrigerator is controlled to operate in an extreme cooling mode.

[0052] In step S102, if the ultra-fast cooling completion condition is met, the vehicle refrigerator is controlled to switch from the ultra-fast cooling mode to the normal cooling mode.

[0053] The vehicle refrigerator has an operating mode including a normal cooling mode and an ultra-fast cooling mode. The lower limit of the temperature range of the ultra-fast cooling mode is lower than the lower limit of the temperature range of the normal cooling mode, and the target cooling temperature of the vehicle refrigerator is within the temperature range of the normal cooling mode.

[0054] A load is items that a user places in a car refrigerator for cooling. A newly added load in a car refrigerator can be caused by a user adding new items to the refrigerator that require cooling. The car refrigerator can determine whether a new load has been added independently or in response to instructions from the user or other device. For example, the car refrigerator can receive instructions sent by a mobile terminal connected to it via wireless communication technology.

[0055] The target refrigeration temperature of the car refrigerator is the temperature that the load in the car refrigerator is expected to reach after refrigeration. It can be the temperature set by the user in the control panel (for example, the refrigerator compartment is set to 2°C and the freezer compartment is set to -18°C), or the temperature set at the factory.

[0056] The conventional cooling mode may be, for example, the cooling mode used by vehicle refrigerators in related art. The temperature range of the conventional cooling mode is the range within which the temperature hysteresis of the vehicle refrigerator is controlled in the conventional cooling mode. The temperature range of the ultra-fast cooling mode is the range within which the temperature hysteresis of the vehicle refrigerator is controlled in the ultra-fast cooling mode.

[0057] The target cooling temperature of the vehicle refrigerator may be within the temperature range of the conventional cooling mode, and may be an upper limit or a lower limit, or a temperature between the upper limit and the lower limit.

[0058] For example, if the target cooling temperature for a car refrigerator's refrigerator compartment is 3°C, the normal cooling mode has a temperature range of 2-4°C, with 4°C being the upper limit and 2°C being the lower limit. The extreme cooling mode has a temperature range of 0-2°C, with 2°C being the upper limit and 0°C being the lower limit.

[0059] Hysteresis within a temperature range refers to oscillations within that range. For example, when the temperature inside a car refrigerator reaches the upper limit of the range, the refrigerator can be controlled to start cooling, causing the temperature inside the refrigerator to drop. When the temperature inside the car refrigerator reaches the lower limit of the range, the refrigerator can be controlled to stop cooling and maintain warmth. The temperature inside the car refrigerator can be converted from the evaporation temperature detected by the temperature sensor installed inside the car refrigerator.

[0060] The conditions for achieving rapid cooling can be pre-set or determined in real time. If these conditions are met, the system can be considered to have achieved a good cooling effect after adding the new load, and the temperature of the new load is close to the target cooling temperature. At this point, the system can switch to normal cooling mode to save power.

[0061] Because the lower limit of the temperature range in the ultra-fast cooling mode is lower than the lower limit of the temperature range in the conventional cooling mode, the vehicle refrigerator cools faster in ultra-fast cooling mode than in the conventional cooling mode. The upper limit of the temperature range in the ultra-fast cooling mode can be higher or lower than the upper limit of the temperature range in the conventional cooling mode, but is preferably lower than the upper limit of the temperature range in the conventional cooling mode. When the upper limit of the temperature range in the ultra-fast cooling mode is lower than the lower limit of the temperature range in the conventional cooling mode, the cooling speed is faster and the cooling effect is better.

[0062] Through the above technical solution, a new ultra-fast cooling mode is added to the car refrigerator. When a new load is added to the car refrigerator, the car refrigerator is controlled to operate in the ultra-fast cooling mode, and when the ultra-fast cooling completion conditions are met, the car refrigerator is controlled to switch from the ultra-fast cooling mode to the conventional cooling mode. Because the lower limit of the temperature range of the ultra-fast cooling mode is lower than the lower limit of the temperature range of the conventional cooling mode, when a new load is added to the car refrigerator, the temperature rise in the car refrigerator caused by the new load can be quickly reduced, thereby enabling the load to be cooled more quickly, improving the user experience. In addition, the implementation method of this solution is simple, and there is no need for long-term experiments to develop control strategies, which saves experimental costs and facilitates rapid application.

[0063] The temperature range for the extreme cooling mode can be fixed or determined in real time. It can be automatically adjusted based on the vehicle refrigerator's environment and load, or modified based on user settings. In another embodiment, before controlling the vehicle refrigerator to operate in the extreme cooling mode, the method further includes: determining the temperature range for the extreme cooling mode.

[0064] There are various ways to determine the temperature range for extreme cooling mode. For example, it can be determined based on factors such as the humidity in the passenger compartment, the ambient temperature and humidity outside the vehicle, and the weight of the newly added load. For example, considering the ambient temperature outside the vehicle, when the ambient temperature outside the vehicle is below a temperature threshold (e.g., 0°C), the lower limit of the temperature range for extreme cooling mode can be set higher than when the ambient temperature outside the vehicle is above the temperature threshold, given that the newly added load may be outside the vehicle and its own temperature is lower.

[0065] In this embodiment, the temperature range of the extreme cooling mode can be determined in real time according to actual conditions, making the extreme cooling of new loads more flexible.

[0066] In addition, the temperature range of the conventional refrigeration mode can also be determined in real time based on the target refrigeration temperature, and can also be automatically adjusted according to the environment and load of the car refrigerator, or changed according to the user's settings.

[0067] In yet another embodiment, determining the temperature range of the extreme cooling mode includes:

[0068] The temperature range of the extreme cooling mode is determined according to the temperature in the passenger compartment and influencing factors: the influencing factors include at least one of the heat load of the newly added load and the target cooling temperature.

[0069] Because the new load in the vehicle refrigerator is in the passenger compartment before being placed inside the vehicle refrigerator, the temperature inside the passenger compartment will affect the temperature of the new load. Therefore, the temperature inside the passenger compartment can be used as an influencing factor in determining the temperature range of the extreme cooling mode. The appropriate extreme cooling intensity can be determined accordingly based on the temperature inside the passenger compartment. When the temperature inside the passenger compartment is high (e.g., above a threshold), the extreme cooling intensity can be greater, and the lower limit of the temperature range of the extreme cooling mode or the overall temperature of the range can be lower. When the temperature inside the passenger compartment is low (e.g., below a threshold), the extreme cooling intensity requirement can be less, and the lower limit of the temperature range of the extreme cooling mode or the overall temperature of the range can be higher.

[0070] The heat load of the newly added load can be calculated based on the mass, temperature, material and other parameters of the newly added load, and is the heat load that the car refrigerator needs to bear. For example, the user can directly input the mass, temperature, material and other parameters of the item on the display screen of the car refrigerator, and the controller of the car refrigerator will determine the heat load of the newly added load through a predetermined algorithm. Alternatively, the car refrigerator can automatically weigh the load and estimate the heat load based on the mass of the newly added load. The larger the load mass, the slower the cooling speed. If you want to cool the load extremely quickly, the estimated heat load for a larger load mass is larger, and the lower limit of the temperature range of the extremely fast cooling mode or the overall temperature of the range can be lower; for a smaller load mass, the estimated heat load is smaller, and the lower limit of the temperature range of the extremely fast cooling mode or the overall temperature of the range can be higher.

[0071] The target cooling temperature can also be a factor in determining the temperature range for rapid cooling mode. For higher target cooling temperatures, the lower limit of the rapid cooling mode temperature range, or the overall temperature range, can be higher; for lower target cooling temperatures, the lower limit of the rapid cooling mode temperature range, or the overall temperature range, can be lower.

[0072] In this embodiment, the temperature range of the extreme cooling mode is determined in real time according to one or more influencing factors, and the extreme cooling has better flexibility.

[0073] In yet another embodiment, determining the temperature range of the extreme cooling mode based on the temperature in the passenger compartment and influencing factors includes:

[0074] In the predetermined first corresponding relationship, a temperature range corresponding to the current temperature in the passenger compartment and the current influencing factors is found as the temperature range of the extreme cooling mode.

[0075] The first corresponding relationship includes the corresponding relationship between the current temperature in the passenger compartment, the influencing factors, and the temperature range.

[0076] The first correspondence can be determined in advance by experiments using an interpolation method and stored. During the operation of the vehicle air conditioner, the temperature range of the extreme cooling mode can be determined directly by searching, which is simple, reliable and fast.

[0077] In another embodiment, after controlling the vehicle refrigerator to operate in the extreme cooling mode, the method further includes: updating the temperature range of the extreme cooling mode according to the temperature change rate in the vehicle refrigerator after the new load is added.

[0078] The temperature change rate in a car refrigerator refers to the amount of temperature change per unit time in the car refrigerator, which reflects the speed of the temperature change in the car refrigerator. The temperature change rate can be positive (temperature increase) or negative (temperature decrease). For example, if the temperature change rate is positive and large, it means that the addition of a new load and the operation of the refrigerator in extreme cooling mode have caused a rapid temperature rise in the refrigerator. In this case, the lower limit of the temperature range of the extreme cooling mode or the overall temperature of the range can be updated to a lower value; if the temperature change rate is negative and large, it means that the addition of a new load and the operation of the refrigerator in extreme cooling mode have caused a rapid temperature drop in the refrigerator. In this case, the lower limit of the temperature range of the extreme cooling mode or the overall temperature of the range can be updated to a higher value.

[0079] In this embodiment, the temperature change rate in the vehicle refrigerator after the new load is added is taken into account to adjust the temperature range of the extreme cooling mode in real time, so that the extreme cooling is matched with the load and the cooling strategy is more flexible.

[0080] In another embodiment, the extreme cooling completion condition includes at least one of the following:

[0081] The temperature inside the car refrigerator reaches the hysteresis threshold within the temperature range of the extreme cooling mode.

[0082] The vehicle refrigerator has been in extreme cooling mode for a certain period of time, reaching the threshold.

[0083] Hysteresis refers to a back-and-forth oscillation. Typically, when the temperature inside a car refrigerator reaches the upper limit of its temperature range, the refrigerator is controlled to start cooling, causing the temperature inside to drop. When the temperature inside the car refrigerator reaches the lower limit of the temperature range, the refrigerator is controlled to stop cooling and maintain the temperature. Therefore, the temperature inside the car refrigerator will hysteresis within the temperature range. One hysteresis period is the time from the temperature inside the car refrigerator reaching the lower limit of the temperature range to the next time it reaches the lower limit.

[0084] FIG2 is a graph showing the temperature change over time in a car refrigerator provided by an exemplary embodiment. As shown in FIG2 , the horizontal axis represents time, and the vertical axis represents the temperature in the car refrigerator. Starting from the moment t=0, there is a new load in the car refrigerator, and the car refrigerator enters the extreme cooling mode. The temperature interval of the extreme cooling mode is the temperature interval of [T2, T1]. The lower limit of the temperature interval of the extreme cooling mode is T2, and the upper limit is T1. The temperature interval of the conventional cooling mode is the temperature interval of [T4, T3]. The lower limit of the temperature interval of the conventional cooling mode is T4, and the upper limit is T3. At time t1, the temperature in the car refrigerator reaches the lower limit T2 of the temperature interval of the extreme cooling mode, and reaches the lower limit T2 again at time t2. From time t1 to time t2, there can be a hysteresis interval.

[0085] In the embodiment of Figure 2 , the threshold number is 3. The temperature inside the vehicle refrigerator reaches the lower limit T2 of the temperature range in the extreme cooling mode four times, at times t1, t2, t3, and t4, respectively. Afterward, the vehicle refrigerator can be controlled to enter the normal cooling mode, with the temperature inside the vehicle refrigerator hysteresis within the normal cooling mode temperature range [T4, T3].

[0086] When the temperature inside the car refrigerator reaches a hysteresis threshold within the temperature range of the extreme cooling mode, it is generally considered that the temperature of the new load is close to the target cooling temperature and it can be switched to the normal cooling mode without extreme cooling.

[0087] In addition, the duration of the car refrigerator's rapid cooling mode operation can also reflect the cooling effect. When the car refrigerator enters the rapid cooling mode operation time threshold, it can also be considered that the temperature of the new load is close to the target cooling temperature.

[0088] In this embodiment, the timing of switching from the ultra-fast cooling mode to the normal cooling mode is determined by the number of hysteresis times and the operating time, thereby saving energy while ensuring the ultra-fast cooling effect.

[0089] The number threshold can be predetermined or determined in real time during vehicle air conditioning operation. In another embodiment, the method further includes determining the number threshold based on the passenger compartment temperature and influencing factors. The influencing factors include at least one of the heat load of the newly added load and the target cooling temperature.

[0090] Because the cabin temperature, the heat load of the newly added load, and the target cooling temperature all reflect the extent of the extreme cooling demand to a certain extent, the frequency threshold can be determined similarly to the temperature range of the extreme cooling mode based on these factors. For example, the higher the cabin temperature, the higher the frequency threshold; the greater the heat load of the newly added load, the higher the frequency threshold; and the lower the target cooling temperature, the higher the frequency threshold.

[0091] In this embodiment, the number threshold is determined in real time according to one or more influencing factors, and the extreme cooling has better flexibility.

[0092] In yet another embodiment, determining the number threshold based on the cabin temperature and influencing factors includes searching a predetermined second correspondence for a number corresponding to the current cabin temperature and the current influencing factors, and using that number threshold as the number threshold. The second correspondence includes a correspondence between the cabin temperature, the influencing factors, and the number of times.

[0093] The second corresponding relationship can be determined in advance based on experiments and stored by using an interpolation method, for example. During the operation of the vehicle air conditioner, the number threshold can be determined directly by searching, which is simple, reliable, and fast.

[0094] In another embodiment, after determining the number threshold according to the temperature in the passenger compartment and influencing factors, the method further includes: updating the number threshold according to the temperature change rate in the vehicle refrigerator after the new load is added.

[0095] If the temperature change rate is positive and large, it means that the new load is added and the refrigerator is running in extreme cooling mode, resulting in a faster temperature rise in the refrigerator. At this time, in order to make the extreme cooling more stable, the number threshold can be updated to a larger value; if the temperature change rate is negative and large, it means that the new load is added and the refrigerator is running in extreme cooling mode, resulting in a faster temperature drop in the refrigerator. At this time, in order to reduce the power consumption of the car refrigerator, the number threshold can be updated to a smaller value.

[0096] In this embodiment, the temperature change rate in the vehicle refrigerator after the new load is added is taken into consideration to adjust the number threshold in real time, so that the extreme cooling is matched with the load and the cooling strategy is more flexible.

[0097] In another embodiment, the method may further include: determining that a new load is added to the vehicle refrigerator if the following conditions are met: the vehicle refrigerator door is opened; and / or the load-bearing capacity of the storage shelf of the vehicle refrigerator increases.

[0098] The vehicle refrigerator may be provided with a weight detection device to detect the shelf load, that is, the mass of the load in the vehicle refrigerator. When the detected shelf load increment exceeds a threshold value (e.g., 200g), it may be determined that the shelf load of the vehicle refrigerator has increased.

[0099] Alternatively, when it is detected that the door of the vehicle refrigerator is opened, it is assumed that a new load has been added to the vehicle refrigerator.

[0100] In this embodiment, whether a new load is added is determined by opening the vehicle refrigerator door and / or increasing the load-bearing capacity of the storage rack.

[0101] FIG3 is a flow chart of a control method for a vehicle refrigerator provided by another exemplary embodiment. As shown in FIG3 , the control method for a vehicle refrigerator includes the following steps:

[0102] 1) Detect whether the car refrigerator door is open;

[0103] 2) If turned on, it will enter the extreme cooling mode;

[0104] 3) The number of rapid cooling hysteresis is reset to zero, and the rapid cooling time is reset to zero;

[0105] 4) If the number of hysteresis times reaches the number threshold, or the running time of the extreme cooling mode reaches the time threshold, the normal cooling mode is entered.

[0106] Based on the same inventive concept, the present disclosure also provides a control device for a vehicle refrigerator. The vehicle refrigerator's operating modes include a normal cooling mode and an extreme cooling mode, and the target cooling temperature of the vehicle refrigerator is within the temperature range of the normal cooling mode. Figure 4 is a block diagram of a control device for a vehicle refrigerator according to an exemplary embodiment. As shown in Figure 4, the control device 400 for a vehicle refrigerator includes a first control module 401 and a second control module 402.

[0107] The first control module 401 is used to control the vehicle refrigerator to operate in an extreme cooling mode when a new load is added to the vehicle refrigerator.

[0108] The second control module 402 is configured to control the vehicle refrigerator to switch from the extreme cooling mode to the normal cooling mode if the extreme cooling completion condition is met.

[0109] The lower limit of the temperature range of the extreme cooling mode is lower than the lower limit of the temperature range of the normal cooling mode.

[0110] Optionally, the control device 400 of the vehicle refrigerator further includes a first determining module.

[0111] The first determining module is used to determine a temperature range of the extreme cooling mode.

[0112] Optionally, the first determining module includes a first determining submodule.

[0113] The first determining submodule is configured to determine a temperature range of the extreme cooling mode according to the temperature in the passenger compartment and influencing factors, where the influencing factors include at least one of a heat load of a newly added load and a target cooling temperature.

[0114] Optionally, the first determination submodule is also used to: in a predetermined first corresponding relationship, find a temperature range corresponding to the current temperature in the passenger compartment and the current influencing factors as the temperature range of the extreme cooling mode, wherein the first corresponding relationship includes the correspondence between the temperature in the passenger compartment, the influencing factors and the temperature range.

[0115] Optionally, the control device 400 of the vehicle refrigerator further includes a first update module.

[0116] The first updating module is used to update the temperature range of the extreme cooling mode according to the temperature change rate in the vehicle refrigerator after the new load is added.

[0117] Optionally, the extreme rapid cooling completion condition satisfies at least one of the following:

[0118] The temperature inside the car refrigerator reaches the hysteresis threshold within the temperature range of the extreme cooling mode.

[0119] The vehicle refrigerator has been in extreme cooling mode for a certain period of time, reaching the threshold.

[0120] Optionally, the control device 400 of the vehicle refrigerator further includes a second determining module.

[0121] The second determination module is configured to determine a number threshold according to the temperature in the passenger compartment and an influencing factor, where the influencing factor includes at least one of a heat load of a newly added load and a target cooling temperature.

[0122] Optionally, the second determination module is also used to: in a predetermined second correspondence, find the number of times corresponding to the current temperature in the passenger compartment and the current influencing factors as a number threshold, wherein the second correspondence includes the correspondence between the temperature in the passenger compartment, the influencing factors and the number of times.

[0123] Optionally, the control device 400 of the vehicle refrigerator further includes a second update module.

When a new load is added to the car refrigerator, the car refrigerator is controlled to operate in the ultra-fast cooling mode, and when the ultra-fast cooling completion conditions are met, the car refrigerator is controlled to switch from the ultra-fast cooling mode to the conventional cooling mode. Because the lower limit of the temperature range of the ultra-fast cooling mode is lower than the lower limit of the temperature range of the conventional cooling mode, when a new load is added to the car refrigerator, the temperature rise in the car refrigerator caused by the new load can be quickly reduced, thereby enabling the load to be cooled more quickly, improving the user experience.
