Description

Technical Field

[0001] This application relates to the field of vehicle-mounted refrigerator technology, and in particular to a method, apparatus, equipment and storage medium for operating a vehicle-mounted refrigerator. Background Technology

[0002] Car refrigerators are portable refrigerators carried in cars, and are a new generation of refrigeration and cooling appliances that have become popular in the international market in recent years. As an extension of household refrigerators, car refrigerators can better preserve food, medicine, and other items while traveling, bringing convenience to people. Car refrigerators can use semiconductor electronic refrigeration technology or compressor refrigeration. Currently, car refrigerators can be used not only when the vehicle is powered on but also when the vehicle is powered off, to better preserve the food inside. However, when the vehicle is powered off and unattended, meaning the car refrigerator continues to operate uncontrollably, the vehicle battery will be continuously drained by the car refrigerator until the vehicle battery is depleted.

[0003] In the prior art, the vehicle status and battery level are determined in real time. In response to determining that the battery level is less than or equal to a preset threshold and the vehicle status is either powered on or started, the vehicle refrigerator is controlled to turn off. In response to turning off the vehicle refrigerator, a delay switch for setting the operating time of the vehicle refrigerator is turned off. In response to determining that the battery level is greater than the threshold and the vehicle status is either powered on or started, the delay switch is turned on for the vehicle refrigerator. In response to determining that the operating time is set for the vehicle refrigerator, the vehicle refrigerator is turned on when the vehicle status changes to powered off. Based on the timing of the operating time, the vehicle refrigerator is controlled to be in an on / off state, thereby intelligently and rationally controlling the operation of the vehicle refrigerator.

[0004] However, controlling the operation of the car refrigerator simply by turning it on and / or off can still lead to the problem of the vehicle's battery draining too quickly. Summary of the Invention

[0013] In one possible design, determining the power level of the vehicle refrigerator based on the vehicle operating status, the ambient temperature, and the battery charge further includes: if the vehicle operating status is the hibernation state in the power-off state, determining the power level of the vehicle refrigerator to be the fourth level.

[0014] In one possible design, determining the power level of the vehicle refrigerator based on the vehicle operating state, the ambient temperature, and the battery charge further includes: if the vehicle operating state is a power-off, temporarily disconnected state, and the ambient temperature where the vehicle refrigerator is located is greater than a preset ambient temperature threshold, determining the power level of the vehicle refrigerator to be the second level; if the vehicle operating state is a power-off, temporarily disconnected state, and the ambient temperature where the vehicle refrigerator is located is less than or equal to the ambient temperature threshold, determining the power level of the vehicle refrigerator to be the third level.

[0015] In one possible design, the method further includes setting the vehicle refrigerator to a shutdown mode if the battery charge is less than or equal to the first charge threshold.

[0016] In one possible design, the method further includes: detecting the internal temperature of the vehicle refrigerator; if the internal temperature is less than or equal to a preset internal temperature threshold, then setting the vehicle refrigerator to a closed mode; otherwise, setting the vehicle refrigerator to an open mode.

[0017] Secondly, this application provides an operation control device for a vehicle-mounted refrigerator, comprising:

[0019] The determination module is used to determine the power level of the vehicle refrigerator based on the vehicle operating status, the ambient temperature, and the battery power if the battery power is greater than a preset first power threshold.

[0020] The control module is used to control the operation of the vehicle refrigerator according to the operating power corresponding to the power level.

[0021] Thirdly, this application provides an operation control device for a vehicle-mounted refrigerator, comprising:

[0022] Processor, memory, communication interface;

[0032] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0034] In existing technology, the vehicle's status and battery level are determined in real time. In response to determining that the battery level is less than or equal to a preset threshold and the vehicle is either powered on or running, the vehicle refrigerator is turned off. In response to turning off the refrigerator, a delay switch for setting the refrigerator's operating time is also turned off. In response to determining that the battery level is greater than a threshold and the vehicle is either powered on or running, the delay switch for the refrigerator is turned on. In response to determining the set operating time for the refrigerator, it is turned on when the vehicle is powered off, and the refrigerator is controlled to be in an on / off state based on the timing of the operating time. This intelligently and rationally controls the operation of the vehicle refrigerator. However, controlling the refrigerator's operation solely by turning it on and / or off still leads to the problem of excessively rapid battery drain in the vehicle.

[0035] This application detects the ambient temperature of the vehicle-mounted refrigerator, the vehicle's operating status, and the battery level. If the battery level exceeds a preset first threshold, the power level of the refrigerator is determined based on the vehicle's operating status, ambient temperature, and battery level. The refrigerator's operation is then controlled according to the corresponding power level. This process of determining the refrigerator's power level based on these factors, and controlling its operation accordingly, improves the intelligence of the refrigerator's control, conserves battery power, and extends its operating time.

[0036] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0037] Figure 1 This is a flowchart illustrating the operation control method for a vehicle-mounted refrigerator provided in the first embodiment of this application, with the vehicle control system as the executing entity.

[0038] like Figure 1 As shown, the operation control method for the vehicle-mounted refrigerator in this embodiment may include the following steps:

[0039] Step S101: Detect the ambient temperature of the vehicle refrigerator, the vehicle operating status of the vehicle where the vehicle refrigerator is located, and the battery level.

[0040] Specifically, the system can detect the ambient temperature of the vehicle-mounted refrigerator, the vehicle's operating status, and the battery level. The ambient temperature refers to the real-time temperature outside the refrigerator. Optionally, this application does not limit the method of detecting the ambient temperature; it can be detected using a temperature sensor or similar device located outside the refrigerator. The vehicle-mounted refrigerator controlled by the method provided in this application can be powered by the vehicle's battery. Optionally, the refrigerator can be connected to the vehicle via a refrigerator power interface located in the vehicle. The battery level refers to the charge level of the vehicle's battery.

[0041] Step S102: If the battery power is greater than the preset first power threshold, determine the power level of the vehicle refrigerator based on the vehicle operating status, ambient temperature and battery power.

[0042] Specifically, according to the detection in step S101, if the battery level is greater than a preset first power threshold, the power level of the vehicle refrigerator can be determined based on the detected vehicle operating status, ambient temperature, and battery level. The first power threshold can be preset according to user needs, and can be set as a power warning value for the vehicle, for example, 10% of the full charge. If the battery level is less than or equal to the warning value, the vehicle's battery is too low. To ensure basic vehicle operation, the refrigerator needs to be turned off, i.e., put into sleep mode, to conserve battery power. The power level refers to the power level at which the vehicle refrigerator operates. Optionally, the parameters for each power level can be preset according to user needs. Specifically, the number of power levels and the power threshold range for each power level can be preset.

[0043] Optionally, the vehicle's operating state can be divided into a power-on state and a power-off state. In the power-on state, if the battery charge is greater than a preset second charge threshold and the ambient temperature of the vehicle refrigerator is greater than a preset ambient temperature threshold, the power level is determined to be the first level, and the second charge threshold is greater than the first charge threshold. If the battery charge is greater than the preset second charge threshold and the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, the power level is determined to be the second level. If the battery charge is less than or equal to the second charge threshold but greater than the first charge threshold, the power level of the vehicle refrigerator is determined to be the second level. Optionally, in the power-off state, if the vehicle's operating state is a sleep state within the power-off state, the power level of the vehicle refrigerator is determined to be the fourth level. If the vehicle's operating state is a temporarily disconnected state within the power-off state and the ambient temperature of the vehicle refrigerator is greater than a preset ambient temperature threshold, the power level of the vehicle refrigerator is determined to be the second level. If the vehicle's operating state is a temporarily disconnected state within the power-off state and the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, the power level of the vehicle refrigerator is determined to be the third level. Among them, the operating power corresponding to the power level decreases sequentially as the power level increases.

[0044] Step S103: Control the operation of the vehicle refrigerator according to the operating power corresponding to the power level.

[0045] Specifically, in step S102, after determining the power level of the vehicle refrigerator based on the vehicle's operating status, the ambient temperature of the vehicle refrigerator, and the battery level of the vehicle refrigerator, the vehicle refrigerator can be controlled to operate according to the operating power corresponding to the determined power level.

[0046] The vehicle-mounted refrigerator operation control method provided in this embodiment detects the ambient temperature of the vehicle where the refrigerator is located, the vehicle's operating status, and the battery level. If the battery level is greater than a preset first power threshold, the power level of the vehicle-mounted refrigerator is determined based on the vehicle's operating status, ambient temperature, and battery level. The refrigerator's operation is then controlled according to the corresponding power level. This process of determining the power level of the refrigerator based on these factors, and controlling its operation accordingly, improves the intelligence of the vehicle-mounted refrigerator's operation control, conserves battery power, and extends the refrigerator's operating time.

[0047] exist Figure 1Based on the illustrated embodiment, this application embodiment further proposes that if the battery power is less than or equal to a first power threshold, the vehicle refrigerator is set to a shutdown mode. Specifically, the on / off mode of the vehicle refrigerator can be determined according to the battery power. The on / off mode refers to the control mode that controls the vehicle refrigerator to turn on or off. The on / off mode includes a shutdown mode and an on / off mode. When the vehicle refrigerator's on / off mode is shutdown, the vehicle refrigerator is controlled to turn off, i.e., the vehicle refrigerator is in a dormant state. When the vehicle refrigerator's on / off mode is on / off, the refrigerator is controlled to turn on, i.e., the vehicle refrigerator is in a wake-up state. Specifically, if the battery power is less than or equal to the first power threshold, the vehicle refrigerator is set to shutdown mode, i.e., the vehicle refrigerator is in a dormant state. At this time, the vehicle refrigerator is not running, and therefore the process of determining the power level of the vehicle refrigerator described in step S102 is unnecessary.

[0048] exist Figure 1 Based on the illustrated embodiment, this application further proposes to detect the internal temperature of the vehicle refrigerator; if the internal temperature is less than or equal to a preset internal temperature threshold, the vehicle refrigerator is set to a closed mode; otherwise, the vehicle refrigerator is set to an open mode. Specifically, the on / off mode of the vehicle refrigerator can be determined based on the internal temperature, where the internal temperature refers to the real-time temperature inside the vehicle refrigerator. Optionally, this application does not limit the method of detecting the internal temperature of the vehicle refrigerator; it can be detected by a temperature sensor or other means installed inside the vehicle refrigerator. The internal temperature threshold refers to the temperature at which the vehicle refrigerator can enter a dormant state (closed mode) until the internal temperature exceeds this threshold, at which point the vehicle refrigerator enters a wake-up state (open mode) to conserve the vehicle's battery power. The internal temperature threshold can be preset according to user needs, for example, based on the storage temperature requirements of the items stored in the vehicle refrigerator. Specifically, if the temperature inside the refrigerator is less than or equal to the preset temperature threshold inside the refrigerator, the vehicle refrigerator is set to the off mode, that is, the vehicle refrigerator is in a dormant state. At this time, the vehicle refrigerator is not running, so there is no need to perform the process of determining the power level of the vehicle refrigerator described in step S102.

[0049] Optionally, before determining the vehicle refrigerator's on / off mode to be the off mode due to the battery level being less than or equal to a preset first battery level threshold and / or the internal temperature being less than or equal to a preset internal temperature threshold, if the vehicle refrigerator's on / off mode is determined, as described in steps S102 and S103, the power level of the vehicle refrigerator can be determined based on the vehicle's operating status and battery level, and the vehicle refrigerator's operation can be controlled according to the operating power corresponding to the power level.

[0050] Optionally, if the battery level of the vehicle containing the car refrigerator is greater than a first battery level threshold and the internal temperature is greater than an internal temperature threshold, the car refrigerator's on / off mode is determined to be the "on" mode. Specifically, if the battery level of the vehicle containing the car refrigerator is greater than the first battery level threshold (i.e., the battery warning value), the vehicle's battery level is sufficient to support the use of the car refrigerator beyond the vehicle's basic operating functions. Therefore, if the internal temperature of the car refrigerator is greater than the internal temperature threshold, the car refrigerator's on / off mode is determined to be the "on" mode. Optionally, after determining the car refrigerator's on / off mode to be the "on" mode, as described in steps S102 and S103, the power level of the car refrigerator can be determined based on the vehicle's operating status and battery level, and the car refrigerator's operation can be controlled according to the corresponding operating power.

[0051] Optionally, if the battery charge is greater than or equal to the first charge threshold and the internal temperature is less than or equal to the internal temperature threshold, the vehicle refrigerator's on / off mode is determined to be the off mode. Optionally, before determining the vehicle refrigerator's on / off mode to be the off mode due to the battery charge being greater than or equal to the first charge threshold and the internal temperature being less than or equal to the internal temperature threshold, if the vehicle refrigerator's on / off mode is determined to be the on mode, the power level of the vehicle refrigerator can be determined according to the vehicle's operating status and battery charge, as described in steps S103 and S104, and the vehicle refrigerator's operation can be controlled according to the operating power corresponding to the power level.

[0052] exist Figure 1 Based on the illustrated embodiment, the second embodiment of this application provides a method for determining the power level of a vehicle refrigerator according to the vehicle's operating status, ambient temperature, and battery charge. The power levels include a first level, a second level, a third level, and a fourth level, with the operating power decreasing sequentially as the level increases. The vehicle's operating status includes a power-on state and a power-off state. The power-on state includes the vehicle being in motion, parked, or awakened. The power-off state includes the vehicle being temporarily away or in hibernation. This embodiment elaborates on the process of determining the power level of the vehicle refrigerator based on the vehicle's operating status, ambient temperature, and battery charge.

[0053] Determining the power level of the vehicle refrigerator based on the vehicle's operating status, ambient temperature, and battery charge in this embodiment may include the following steps:

[0054] Steps S201-S203 describe the process of determining the power level based on the battery charge and ambient temperature when the vehicle is in a powered-on state.

[0055] Step S201: If the vehicle is in a powered-on state, the battery charge is greater than the preset second charge threshold, and the ambient temperature of the vehicle refrigerator is greater than the preset ambient temperature threshold, the power level is determined to be the first level, and the second charge threshold is greater than the first charge threshold.

[0056] Specifically, according to the detection in step S101, if the vehicle is in a powered-on state (i.e., the vehicle is in a driving state, or in a parked state, or in a wake-up state (i.e., the vehicle is in use), the battery charge is greater than the preset second charge threshold, and the ambient temperature of the vehicle refrigerator is greater than the preset ambient temperature threshold, the power level is determined to be the first level, and the second charge threshold is greater than the first charge threshold.

[0057] Among them, "driving state" refers to the vehicle being in motion, "parking state" refers to the vehicle being stopped and in P gear, and "wake-up state" refers to the state where the user wakes up the vehicle's control system a certain period of time before using the vehicle, such as through remote signal control. "Vehicle refrigerator environment" refers to the temperature of the ambient temperature around the vehicle refrigerator. Optionally, if the ambient temperature is high, a higher operating power is required to control the vehicle refrigerator, i.e., a higher power level. If the ambient temperature is low, a lower operating power can be used to control the vehicle refrigerator to save battery power. Specifically, the power level of the vehicle refrigerator can be determined by setting an ambient temperature threshold and comparing it with the current ambient temperature. The ambient temperature threshold can be preset according to user needs. The second battery power threshold refers to the battery power threshold at which the vehicle's battery is sufficiently charged to meet the vehicle's basic operating functions for a set period of time. The second battery power threshold can be preset according to user needs, for example, set to 40% of the full charge. Optionally, if the items stored in the vehicle refrigerator are more important, the battery power threshold can be set lower, for example, to 20%.

[0058] Step S202: If the vehicle is in a powered-on state, the battery charge is greater than the preset second charge threshold, and the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, then the power level is determined to be the second level.

[0059] Specifically, according to the detection in step S101, if the vehicle is in a powered-on state and the battery power is greater than the preset second power threshold, as described in step S201 regarding the ambient temperature of the refrigerator, if the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, the power level is determined to be the second level, that is, the current power level is less than the power level when the ambient temperature of the vehicle refrigerator is greater than the preset ambient temperature threshold.

[0060] Step S203: If the vehicle is in a powered-on state and the battery power is less than or equal to the second power threshold and greater than the first power threshold, determine the power level of the vehicle refrigerator to be the second level.

[0061] Specifically, according to the detection in step S101, if the vehicle is in a powered-on state, i.e., in a driving state, a parked state, or a wake-up state, and the battery level is less than or equal to the second power threshold and greater than the first power threshold, the power level of the vehicle refrigerator is determined to be the second level. When the battery level of the vehicle where the vehicle refrigerator is located is less than or equal to the second power threshold and greater than the first power threshold, the vehicle battery is not sufficient to meet the most basic operating functions of the vehicle until the set time described in step S201. However, the battery level of the vehicle where the vehicle refrigerator is located is still greater than the first power threshold, i.e., the power warning value. At this time, the battery level of the vehicle where the vehicle refrigerator is located can support the use of the vehicle refrigerator in addition to ensuring the most basic operating functions of the vehicle. At this time, the operating power of the vehicle refrigerator can be reduced, i.e., the power level is changed from the first level in step S201 to the second level, so as to save the vehicle battery power.

[0062] In the case where the vehicle is powered on, if the battery level drops to a level less than or equal to the second power threshold but greater than the first power threshold, the power level of the vehicle refrigerator needs to be kept above a certain level to ensure its operation during vehicle use. Therefore, in this step, regardless of the ambient temperature of the vehicle refrigerator, the power level is controlled according to the power level when the ambient temperature is higher than the ambient temperature threshold. That is, regardless of whether the ambient temperature of the vehicle refrigerator is higher than the ambient temperature threshold or lower than or equal to the ambient temperature threshold, the power control level is set to the second level.

[0063] Steps S204-306 describe the process of determining the power level based on the battery charge and ambient temperature when the vehicle is in a powered-off state.

[0064] Step S204: If the vehicle is in a dormant state when it is powered off, determine that the power setting of the vehicle refrigerator is the fourth setting.

[0065] Specifically, according to the detection in step S101, if the vehicle's operating state is a dormant state under power-off conditions, the power level of the vehicle refrigerator is determined to be the fourth level. As described above, the power-off state includes: dormant state and temporary absence state. The dormant state refers to the deep dormant state in the normal dormant state, that is, the state that has been in the normal dormant state for more than a certain period of time. When the vehicle's operating state is a dormant state under power-off conditions, the vehicle is not in actual use. At this time, the vehicle refrigerator can be controlled to operate at a lower power, that is, the lowest power level in the preset power levels, the fourth level.

[0066] Step S205: If the vehicle is in a temporarily disconnected state when it is powered off, and the ambient temperature of the vehicle refrigerator is greater than the preset ambient temperature threshold, determine the power level of the vehicle refrigerator to be the second level.

[0067] As described above, the power-off states include: hibernation state and temporary absence state. The temporary absence state refers to the state within a certain period of time when the vehicle has just entered the normal hibernation state, that is, the vehicle starts normal hibernation, but has not entered the deep hibernation state described in step S204. At this time, the user may return to the vehicle and use the vehicle within the above-mentioned certain period of time. Therefore, it is necessary to ensure that the operating power of the vehicle refrigerator is greater than the operating power in the hibernation state described in step S204, that is, greater than or equal to the third level. The temporary absence state is different from the power-on state described in step S201 when the battery charge is greater than the preset second charge threshold and the power level is determined to be the first level. In this case, the vehicle is in a standby state and is not in use. Therefore, even if the battery charge is greater than the second charge threshold, the power level of the vehicle refrigerator is lower than the first level, that is, less than or equal to the second level.

[0068] Specifically, according to the detection in step S101, if the vehicle is in a temporarily disconnected state when it is powered off, regardless of the battery level, that is, regardless of whether the battery level is greater than the second power threshold, less than or equal to the second power threshold, or greater than the first power threshold, as described in step S201 regarding the ambient temperature of the vehicle refrigerator, if the ambient temperature of the vehicle refrigerator is greater than the preset ambient temperature threshold, the power level of the vehicle refrigerator is determined to be the second level.

[0069] Step S206: If the vehicle is in a temporarily disconnected state when it is powered off, and the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, determine the power level of the vehicle refrigerator to be the third level.

[0070] Specifically, as described in step S205 regarding the temporary off-state, regardless of the battery charge, whether the battery charge is greater than or less than or equal to the second charge threshold or greater than the first charge threshold, according to the detection in step S101, if the vehicle is in a temporary off-state during the power-down phase, as described in step S201 regarding the ambient temperature of the vehicle refrigerator, if the ambient temperature of the vehicle refrigerator is less than or equal to the ambient temperature threshold, the power level of the vehicle refrigerator is determined to be the third level.

[0071] Figure 2 This is a schematic diagram illustrating the process of determining the power level of a vehicle-mounted refrigerator, as provided in an embodiment of this application.

[0072] Specifically, when the vehicle refrigerator is in the "on" mode, the system first determines whether the battery charge threshold is greater than a second charge threshold, then determines whether the ambient temperature is greater than an ambient temperature threshold, and finally determines the power level of the vehicle refrigerator based on the vehicle's operating status.
