Description

Technical Field

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

[0002] As an important product in the automotive parts market, the demand for car refrigerators continues to grow. Car refrigerators not only provide drivers and passengers with the convenience of cold drinks and food, but they are also installed in the vehicle and powered by the vehicle's battery.

[0003] Traditional car refrigerators operate according to a preset cooling or heating mode regardless of the vehicle's status. This design may not cause major problems when the vehicle is driving smoothly, but during peak electricity usage periods, such as when climbing hills, driving on mountain roads or encountering frequent traffic jams and stop-and-go traffic in the city, the continuous operation of the car refrigerator will place an additional burden on the vehicle's electrical system. This can lead to the vehicle running out of power during peak hours, making it unable to operate normally. Summary of the Invention

[0004] The main purpose of this application is to provide a control method for a vehicle-mounted refrigerator, a vehicle-mounted refrigerator, a vehicle, and a storage medium, aiming to solve the technical problem that the continuous operation of the vehicle-mounted refrigerator during peak electricity consumption causes the vehicle to run out of power and become unable to operate normally.

[0005] To achieve the above objectives, this application proposes a control method for a vehicle-mounted refrigerator, comprising:

[0006] Obtain the current energy consumption of the vehicle where the in-vehicle refrigerator is located;

[0007] If the current energy consumption is greater than the set energy consumption, control the vehicle refrigerator to operate in energy-saving mode.

[0008] In one embodiment, if the current energy consumption is greater than the set energy consumption, controlling the vehicle refrigerator to operate in energy-saving mode includes:

[0009] If the current energy consumption is greater than the set energy consumption, adjust the control parameters of the vehicle refrigerator;

[0010] Control the vehicle-mounted refrigerator to operate according to the adjusted control parameters;

[0011] If the current energy consumption exceeds the set energy consumption, after controlling the vehicle refrigerator to operate in energy-saving mode, the following will also be included:

[0012] If the current energy consumption is less than or equal to the set energy consumption, control the vehicle refrigerator to operate according to the initial control parameters;

[0013] The control parameters include at least one of the following: start-up temperature, stop-down temperature, and compressor speed.

[0014] In one embodiment, the control method for a vehicle-mounted refrigerator further includes:

[0015] Get the first energy consumption of the vehicle refrigerator when it runs according to the adjusted control parameters, under the condition that the current energy consumption is greater than the set energy consumption.

[0016] Get the second energy consumption of the vehicle refrigerator when it is running according to the initial control parameters, provided that the current energy consumption is less than or equal to the set energy consumption.

[0017] Among them, the sum of the first energy consumption and the second energy consumption equals the optimal energy consumption of the vehicle refrigerator during vehicle operation. The start-up temperature and the stop temperature are negatively correlated with the start-up time of the vehicle refrigerator. The compressor speed of the vehicle refrigerator is positively correlated with the compressor operating power. The start-up time and the compressor operating power are positively correlated with the first energy consumption and the second energy consumption.

[0018] In one embodiment, if the current energy consumption is greater than the set energy consumption, adjusting the control parameters of the vehicle refrigerator includes:

[0019] If the current energy consumption is greater than the set energy consumption, obtain the current working mode of the vehicle refrigerator;

[0020] Adjust the control parameters of the vehicle refrigerator in the working mode.

[0021] In one embodiment, if the operating mode is cooling mode, adjusting the control parameters of the vehicle refrigerator in the operating mode includes at least one of increasing the start-up temperature of the vehicle refrigerator, increasing the stop-up temperature of the vehicle refrigerator, and decreasing the compressor speed of the vehicle refrigerator.

[0022] Alternatively, if the operating mode is heating mode, adjusting the control parameters of the vehicle refrigerator in the operating mode includes at least one of the following: reducing the start-up temperature of the vehicle refrigerator, reducing the shutdown temperature of the vehicle refrigerator, and reducing the compressor speed of the vehicle refrigerator.

[0023] In one embodiment, the control method for a vehicle-mounted refrigerator includes:

[0024] Obtain the vehicle's current driving status;

[0025] If the vehicle is in the target driving state and the current energy consumption is greater than the set energy consumption, control the vehicle refrigerator to operate in energy-saving mode.

[0026] In one embodiment, obtaining the current driving status of the vehicle includes:

[0027] Obtain the vehicle's tilt angle and acceleration;

[0028] The vehicle's current driving status is determined based on the tilt angle and acceleration.

[0029] In addition, to achieve the above objectives, this application also proposes a vehicle refrigerator, including: a memory, a processor, and a computer program stored on the memory and executable on the processor, the computer program being configured to implement the steps of the vehicle refrigerator control method described above.

[0030] In addition, to achieve the above objectives, this application also proposes a vehicle including the aforementioned vehicle-mounted refrigerator.

[0031] In addition, to achieve the above objectives, this application also proposes a storage medium, which is a computer-readable storage medium, on which a computer program is stored, and when the computer program is executed by a processor, it implements the steps of the vehicle refrigerator control method described above.

[0032] This application obtains the vehicle's current energy consumption; if the current energy consumption is greater than the set energy consumption, it controls the onboard refrigerator to operate in energy-saving mode. Since the current energy consumption is greater than the set energy consumption, it indicates that the vehicle is currently in a high-energy-consumption state, that is, the vehicle is currently in peak electricity consumption. At this time, controlling the onboard refrigerator to operate in energy-saving mode can reduce the energy consumption demand of the onboard refrigerator on the overall energy consumption of the vehicle, so that the vehicle can have more electricity to support the vehicle's other power consumption needs. In this way, the vehicle can continue to operate normally when the battery is low during peak electricity consumption. Attached Figure Description

[0041] The purpose, features, and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0042] It should be understood that the specific embodiments described herein are merely illustrative of the technical solutions of this application and are not intended to limit this application.

[0043] To better understand the technical solution of this application, a detailed description will be provided below in conjunction with the accompanying drawings and specific implementation methods.

[0044] From its initial simple refrigeration function, the car refrigerator has evolved into a modern product with multiple functions such as refrigeration, heating, and intelligent control. It not only meets the convenient needs of drivers and passengers for cold drinks, cold food, hot drinks, and hot food, but has also become an important accessory to enhance the driving experience and quality of life.

[0045] Early car refrigerators were relatively simple in design, relying primarily on the vehicle battery for power and employing traditional refrigeration technology. These refrigerators could maintain a good internal temperature when the vehicle was moving smoothly, providing passengers with cold drinks and food. However, with the diversification of automotive usage environments, the design of traditional car refrigerators gradually revealed some problems. Especially during peak power consumption periods, such as when climbing hills or driving on mountain roads requiring greater power output, or in urban environments with frequent traffic jams and stop-and-go traffic, the continuous operation of the car refrigerator placed an additional burden on the vehicle's electrical system.

[0046] To address the aforementioned issues, this application proposes a control method for a vehicle-mounted refrigerator. The main technical solution includes: obtaining the current energy consumption of the vehicle where the refrigerator is located; if the current energy consumption is greater than the set energy consumption, controlling the vehicle-mounted refrigerator to operate in an energy-saving mode.

[0047] This application obtains the vehicle's current energy consumption; if the current energy consumption is greater than the set energy consumption, it controls the onboard refrigerator to operate in energy-saving mode. Since the current energy consumption is greater than the set energy consumption, it indicates that the vehicle is currently in a high-energy-consumption state, that is, the vehicle is currently in peak electricity consumption. At this time, controlling the onboard refrigerator to operate in energy-saving mode can reduce the energy consumption demand of the onboard refrigerator on the overall energy consumption of the vehicle, so that the vehicle can have more electricity to support the vehicle's other power consumption needs. In this way, the vehicle can continue to operate normally when the battery is low during peak electricity consumption.

[0048] It should be noted that the vehicle refrigerator of this application can be an air-cooled vehicle refrigerator. The working principle of an air-cooled vehicle refrigerator mainly involves a built-in fan promoting the circulation of cold air inside the refrigerator to achieve a cooling effect. The vehicle refrigerator of this application can also be other types of vehicle refrigerators, such as a direct-cooling vehicle refrigerator, which relies on natural convection cooling through an evaporator. Compared to a direct-cooling vehicle refrigerator, an air-cooled vehicle refrigerator cools faster; therefore, this application preferably uses an air-cooled vehicle refrigerator. In addition to its cooling function, the air-cooled vehicle refrigerator of this application also has a heating function.

[0049] The air-cooled vehicle refrigerator of this application includes a compressor, condenser, dryer filter, capillary tube, evaporator, and return pipe assembly. During the refrigeration process, the compressor is the heart of the refrigeration system, providing power to the entire system. It compresses the low-pressure gaseous refrigerant at room temperature into a high-temperature, high-pressure gaseous refrigerant. The condenser dissipates heat from the refrigeration system, condensing the high-temperature, high-pressure gas discharged from the compressor into a low-temperature, high-pressure liquid. The dryer filter absorbs moisture and impurities in the system, preventing ice blockage and dirt blockage. The capillary tube acts as a throttling and pressure-reducing element. The evaporator employs a dual-evaporator design, where the refrigerant changes from liquid to gas, absorbing heat from the interior of the refrigerator to achieve the refrigeration effect. The return pipe assembly contains the low-temperature gaseous refrigerant from the evaporator, which exchanges heat with the capillary tube and becomes a low-temperature gaseous refrigerant.

[0050] In practical applications, when the air-cooled car refrigerator is in cooling mode, if the temperature sensor inside the refrigerator has not reached the shutdown temperature, the compressor will start and the bottom cooling fan will run to begin cooling until the temperature sensor inside the refrigerator reaches the shutdown temperature, at which point cooling will stop. When the air-cooled car refrigerator is in heating mode, if the temperature sensor has not reached the start-up temperature, the heating element will turn on to begin heating until the temperature sensor reaches the start-up temperature, at which point heating will stop.

[0051] It should be noted that the vehicle refrigerator is located in the vehicle and is connected to the vehicle's electrical system along with other electrical modules, such as the motor drive module and control module. It is powered by the vehicle's electrical system. Therefore, when the vehicle's power consumption is high, some of the vehicle refrigerator's power consumption can be sacrificed, so that more power can support the use of other electrical modules, allowing the vehicle to operate normally during peak power consumption periods.

[0052] Based on this, this application provides a control method for a vehicle-mounted refrigerator, referring to... Figure 1 , Figure 1 This is a flowchart illustrating some embodiments of the control method for a vehicle-mounted refrigerator according to this application.

[0053] In some embodiments of this application, the control method for a vehicle-mounted refrigerator includes steps S10 to S20:

[0054] Step S10: Obtain the current energy consumption of the vehicle where the in-vehicle refrigerator is located.

[0055] A vehicle's current energy consumption reflects its energy efficiency and energy consumption during current driving. For gasoline-powered vehicles, energy consumption can be expressed as fuel consumption, representing the amount of fuel consumed during operation. For electric vehicles or other new energy vehicles, energy consumption can be expressed as the amount of electricity consumed. A vehicle's current energy consumption is typically measured per unit distance traveled; for example, fuel consumption can be expressed as liters per 100 kilometers, and electricity consumption as kilowatt-hours per 100 kilometers.

[0056] Information can be directly read from the vehicle's dashboard, including instantaneous fuel consumption and average energy consumption. Average energy consumption refers to the average amount of fuel consumed by the vehicle over a certain driving distance. Alternatively, the vehicle's fuel consumption monitor or energy management system can be used to measure and record the vehicle's energy consumption and display the current energy consumption during driving on the vehicle's trip computer display. Alternatively, third-party applications or smart devices can be used to read the vehicle's energy consumption data; for example, a smartphone can connect to the vehicle via Bluetooth or Wi-Fi to provide detailed vehicle information, including energy consumption. By obtaining the current energy consumption of the vehicle where the in-car refrigerator is located, the vehicle's current electricity consumption can be reflected, allowing for control of the in-car refrigerator based on the vehicle's current energy consumption.

[0057] Step S20: If the current energy consumption is greater than the set energy consumption, control the vehicle refrigerator to operate in energy-saving mode.

[0058] The energy consumption setting can be customized according to actual conditions, and can be a fixed setting at the factory. Specifically, the energy consumption setting can differ depending on the vehicle's driving mode, allowing for targeted control of the in-vehicle refrigerator in different driving scenarios. Driving modes can include autonomous driving mode, manual driving mode, and parking mode, among others.

[0059] When a car refrigerator is running in energy-saving mode, its energy consumption is reduced. Although the car refrigerator can still cool or heat when running in energy-saving mode, the cooling or heating effect is reduced.

[0060] If the current energy consumption exceeds the set energy consumption, it indicates that the vehicle is currently in a high-energy-consumption state, meaning the vehicle is currently experiencing peak electricity usage. In this case, controlling the vehicle refrigerator to operate in energy-saving mode can reduce its energy consumption, allowing the vehicle to have more power to support other electrical needs. This ensures that other electrical devices can operate normally when the vehicle experiences a power shortage during peak hours.

[0061] In one feasible implementation, the vehicle refrigerator can be controlled to operate in energy-saving mode if the current energy consumption is greater than the set energy consumption and the duration of this greater-than-set energy consumption is longer than a preset duration. If the duration of the greater-than-set energy consumption is less than or equal to the preset duration, the vehicle refrigerator will operate according to the normal cooling or heating procedure. This setting can avoid misjudging the vehicle's power consumption and achieve precise control of the vehicle refrigerator. The preset duration can be 60 seconds.

[0062] In another feasible implementation, the vehicle refrigerator can be controlled to operate in energy-saving mode when the vehicle's energy consumption change rate exceeds a preset change rate. Energy-saving mode is a low-power operating mode designed for vehicle refrigerators. When the vehicle refrigerator operates in this mode, it intelligently adjusts the operating parameters of the refrigeration system to reduce energy consumption. Therefore, switching the vehicle refrigerator to energy-saving mode promptly when the vehicle's energy consumption change rate is abnormal can significantly reduce the refrigerator's energy consumption, thereby alleviating the overall energy burden on the vehicle.

[0063] In this embodiment, the vehicle's current energy consumption is obtained; if the current energy consumption is greater than a set energy consumption, the vehicle refrigerator is controlled to operate in energy-saving mode. Since the current energy consumption is greater than the set energy consumption, it indicates that the vehicle is currently in a high-energy-consumption state, that is, the vehicle is currently in peak electricity consumption. Controlling the vehicle refrigerator to operate in energy-saving mode at this time can reduce the energy consumption demand of the vehicle refrigerator on the overall energy consumption of the vehicle, so that the vehicle can have more electricity to support the vehicle's other power consumption needs. In this way, the vehicle can operate normally when the battery is low during peak electricity consumption.

[0064] Reference Figure 2 In some embodiments of this application, if the current energy consumption is greater than the set energy consumption, controlling the vehicle refrigerator to operate in energy-saving mode includes:

[0065] Step S21: If the current energy consumption is greater than the set energy consumption, adjust the control parameters of the vehicle refrigerator.

[0066] The control parameters include at least one of the following: start-up temperature, stop-down temperature, and compressor speed. Additionally, control parameters may include fan speed, etc. The start-up temperature refers to the temperature at which the vehicle refrigerator is turned on for cooling or heating, and the stop-down temperature refers to the temperature at which the vehicle refrigerator is turned off for cooling or heating.

[0067] Adjusting the control parameters of a car refrigerator includes adjusting at least one of the following: start-up temperature, stop-off temperature, and compressor speed. For the start-up and stop-off temperatures, adjustments can be made in 0.5°C increments until the upper limit of the cooling mode or heating mode is reached. For the compressor speed, adjustments can be made in 100 RPM increments until the upper limit of the compressor speed is reached.

[0068] Step S22: Control the vehicle refrigerator to operate according to the adjusted control parameters.

[0069] When the start-up temperature changes, the required operating time also changes, thus affecting the energy consumption of the car refrigerator. Similarly, when the shutdown temperature changes, the required operating time also changes, thus affecting the energy consumption of the car refrigerator. When the compressor speed changes, the required compressor power also changes, thus affecting the energy consumption of the car refrigerator. In this way, by adjusting at least one of the start-up temperature, shutdown temperature, and compressor speed, the energy consumption of the car refrigerator can be controlled, achieving the effect of energy saving.

[0070] Furthermore, if the current energy consumption exceeds the set energy consumption, after controlling the vehicle refrigerator to operate in energy-saving mode, it also includes:

[0071] Step S30: If the current energy consumption is less than or equal to the set energy consumption, control the vehicle refrigerator to operate according to the initial control parameters.

[0072] If the current energy consumption is less than or equal to the set energy consumption, the vehicle refrigerator is controlled to operate at at least one of the initial start-up temperature, initial stop-up temperature, initial compressor speed, and initial fan speed, so that the vehicle refrigerator can achieve normal cooling or heating effects when the vehicle switches from a high energy consumption state to a low energy consumption state.

[0073] In one feasible implementation, if the current energy consumption is less than or equal to the set energy consumption and the vehicle refrigerator is currently in cooling mode, the vehicle refrigerator is controlled to operate according to at least one of the initial start-up temperature, stop-up temperature and compressor speed corresponding to the cooling mode.

[0074] In another feasible implementation, if the current energy consumption is less than or equal to the set energy consumption and the vehicle refrigerator is currently in heating mode, the vehicle refrigerator is controlled to operate according to at least one of the initial start-up temperature, stop temperature and compressor speed corresponding to the heating mode.

[0075] The control parameters of a vehicle refrigerator vary depending on its operating mode.

[0076] In this embodiment, if the current energy consumption is greater than the set energy consumption, the vehicle can control the energy consumption of the on-board refrigerator by adjusting at least one of the start-up temperature, stop temperature, and compressor speed when the vehicle is in a high-energy-consumption state, thereby achieving energy saving. If the current energy consumption is less than or equal to the set energy consumption, the on-board refrigerator is controlled to operate according to the initial control parameters, so that when the vehicle switches from a high-energy-consumption state to a low-energy-consumption state, the on-board refrigerator can achieve normal cooling or heating effects.

[0077] In other embodiments, if the vehicle remains in a low-energy state during operation, the onboard refrigerator is controlled to continue operating according to the initial control parameters.

[0078] In some embodiments of this application, the control method for a vehicle-mounted refrigerator further includes:

[0079] Step S110: Obtain the first energy consumption of the vehicle refrigerator when it is running according to the adjusted control parameters under the condition that the current energy consumption is greater than the set energy consumption.

[0080] Step S120: Obtain the second energy consumption of the vehicle refrigerator when it is running according to the initial control parameters, under the condition that the current energy consumption is less than or equal to the set energy consumption.

[0081] Among them, the sum of the first energy consumption and the second energy consumption equals the optimal energy consumption of the vehicle refrigerator during vehicle operation. The start-up temperature and the stop temperature are negatively correlated with the start-up time of the vehicle refrigerator. The compressor speed of the vehicle refrigerator is positively correlated with the compressor operating power. The start-up time and the compressor operating power are positively correlated with the first energy consumption and the second energy consumption.

[0082] When operating a vehicle-mounted refrigerator according to the adjusted control parameters, it is necessary to control its overall energy consumption, that is, to control the optimal energy consumption of the refrigerator during vehicle operation. By controlling the optimal energy consumption during vehicle operation, frequent start-ups of the refrigerator can be avoided, as well as excessively long operating times that would lead to increased energy consumption. In the process of controlling the energy consumption of the vehicle-mounted refrigerator, the setting of the refrigerator's operating rate is crucial. It is generally considered that the operating rate should be stable within a suitable range, such as an operating time t. 开 / (Power-on duration t) 开 +Downtime t 停 The energy consumption of a car refrigerator is between 75% and 80%, which is the optimal level, as it avoids frequent power-on or prolonged power consumption.

[0083] The first energy consumption can be determined by multiplying the power of the vehicle refrigerator by the operating time of the vehicle refrigerator when the current energy consumption is greater than the set energy consumption. The second energy consumption can be determined by multiplying the power of the vehicle refrigerator by the operating time of the vehicle refrigerator when the current energy consumption is less than or equal to the set energy consumption.

[0084] The relationship between the first energy consumption, the second energy consumption, and the optimal energy consumption is shown in the following formula:

[0085]

[0086] Among them, in the above formula This indicates the operating rate of the vehicle refrigerator during vehicle operation. This indicates that the vehicle refrigerator is operating at a rate where the current energy consumption exceeds the set energy consumption. This indicates the vehicle refrigerator is operating at a rate where current energy consumption is less than or equal to the set energy consumption. P represents the compressor power corresponding to the maximum cooling capacity the vehicle refrigerator can produce per unit of energy consumption. T represents the vehicle's operating time, including the continuous operating duration from startup to the current moment. Ta represents the duration for which the vehicle's current energy consumption is greater than the set energy consumption. A This indicates that the compressor power (P) of the vehicle is at a current energy consumption level greater than the set energy consumption level. B This indicates the compressor power at which the vehicle's current energy consumption is less than or equal to the set energy consumption. 开A This indicates the duration for which the vehicle refrigerator is powered on when its current energy consumption exceeds the set energy consumption. 停A This indicates the duration the vehicle refrigerator will be off when its current energy consumption exceeds the set energy consumption. 开B This indicates the duration for which the vehicle refrigerator is powered on when its current energy consumption is less than or equal to the set energy consumption. 停B This indicates the downtime of the vehicle refrigerator when its current energy consumption is less than or equal to the set energy consumption. This represents the optimal energy consumption. Indicates the first energy consumption. This indicates the second energy consumption.

[0087] In this embodiment of the application, when the vehicle refrigerator is running according to the adjusted control parameters, it is necessary to control the overall energy consumption of the vehicle refrigerator, that is, to control the optimal energy consumption of the vehicle refrigerator during vehicle operation. By controlling the optimal energy consumption of the vehicle refrigerator during vehicle operation, the frequent start-up of the vehicle refrigerator can be avoided, and the energy consumption of the vehicle refrigerator can also be avoided from increasing due to the long start-up time of the vehicle refrigerator.

[0088] Reference Figure 3 In some embodiments of this application, if the current energy consumption is greater than the set energy consumption, adjusting the control parameters of the vehicle refrigerator includes:

[0089] Step S211: If the current energy consumption is greater than the set energy consumption, obtain the current working mode of the vehicle refrigerator.

[0090] It should be noted that the operating mode of the car refrigerator can be one of the following: cooling mode, heating mode, or defrosting mode.

[0091] In one feasible implementation, the timing for acquiring the operating mode of the vehicle refrigerator can be determined by periodically acquiring the operating mode, in real time acquiring the operating mode of the vehicle refrigerator, or acquiring the operating mode of the vehicle refrigerator when set conditions are met, such as if the vehicle is in a target driving state and the current energy consumption is greater than the set energy consumption, or the vehicle is in a target driving state, or the current energy consumption of the vehicle is greater than the set energy consumption, etc., so as to promptly control the vehicle refrigerator based on the acquired operating mode.

[0092] In another feasible implementation, the method for obtaining the operating mode of the vehicle refrigerator includes, but is not limited to, one or more of the following methods:

[0093] The operating mode of the car refrigerator can be determined through its control panel. Specifically, most car refrigerators have indicator lights or displays on the control panel to show the current operating mode. You can directly observe the information on these indicators or displays to determine the operating mode. Alternatively, you can switch between different operating modes by pressing specific buttons on the panel and view the currently selected mode on the display.

[0094] The operating mode of the in-car refrigerator is also obtained through the vehicle's central control system. Specifically, if the in-car refrigerator is integrated with the vehicle's central control system, its operating mode can be viewed and controlled via the central control screen. The central control screen includes a menu or option to display the refrigerator's status and settings. Alternatively, the operating mode can be remotely viewed and controlled via a mobile application. Users need to download and install the corresponding in-car app and connect to the refrigerator via Bluetooth or Wi-Fi. The refrigerator's operating mode can then be viewed within the application.

[0095] The operating mode of the in-vehicle refrigerator can also be found on the vehicle information display screen. Specifically, some models will display the operating mode of the in-vehicle refrigerator on the vehicle's information display screen, such as the instrument panel or head-up display system. Users can find out the operating mode of the in-vehicle refrigerator by observing the information display screen.

[0096] Step S212: Adjust the control parameters of the vehicle refrigerator in the working mode.

[0097] In one feasible implementation, if the operating mode is cooling mode, adjusting the control parameters of the vehicle refrigerator in this mode includes at least one of: increasing the start-up temperature of the vehicle refrigerator, increasing the stop-off temperature of the vehicle refrigerator, and decreasing the compressor speed of the vehicle refrigerator. It is understood that in cooling mode, when the start-up temperature increases, the required operating time decreases, and the energy consumption of the vehicle refrigerator decreases; if the stop-off temperature increases, the required operating time decreases, and the energy consumption of the vehicle refrigerator decreases; when the compressor speed decreases, the required compressor power also decreases, and the energy consumption of the vehicle refrigerator decreases. Thus, by increasing at least one of adjusting the start-up temperature, increasing the stop-off temperature, and decreasing the compressor speed, the energy consumption of the vehicle refrigerator can be reduced, achieving an energy-saving effect.

[0098] In another feasible implementation, if the operating mode is heating mode, adjusting the control parameters of the vehicle refrigerator in this mode includes at least one of: lowering the start-up temperature of the vehicle refrigerator, lowering the stop-off temperature of the vehicle refrigerator, and lowering the compressor speed of the vehicle refrigerator. It is understood that in heating mode, when the start-up temperature is lowered, the required operating time is shortened, and the energy consumption of the vehicle refrigerator is reduced; if the stop-off temperature is lowered, the required operating time is shortened, and the energy consumption of the vehicle refrigerator is reduced; when the compressor speed is reduced, the required compressor power is also reduced, and the energy consumption of the vehicle refrigerator is reduced. Thus, by adjusting at least one of the start-up temperature, increasing the stop-off temperature, and lowering the compressor speed, the energy consumption of the vehicle refrigerator can be reduced, achieving an energy-saving effect.

[0099] In this embodiment of the application, if the current energy consumption is greater than the set energy consumption, the current working mode of the vehicle refrigerator is obtained, and the control parameters of the vehicle refrigerator under the working mode are adjusted. In this way, the vehicle refrigerator can achieve energy saving effect regardless of the working mode in which the vehicle refrigerator is operating when the vehicle's power consumption increases.

[0100] Reference Figure 4 In some embodiments of this application, the control method for the vehicle-mounted refrigerator includes:

[0101] Step S110: Obtain the current driving status of the vehicle.

[0102] Driving status refers to the state of a vehicle during driving due to the road conditions it encounters. Road conditions include the smoothness, slope, and curvature of the road surface. By determining the road conditions encountered by the vehicle containing the car refrigerator during driving, the driving status of the vehicle can be determined.

[0103] Driving status can be categorized into two types: target driving status and non-target driving status. When a vehicle is in a non-target driving status, the road surface it is currently traveling on is relatively flat or has no slope. When a vehicle is in a target driving status, it means that the road surface it is currently traveling on is uneven or has a large slope. Target driving status can be further subdivided into: vehicle acceleration / deceleration, vehicle uphill / downhill driving, and vehicle driving on rough roads. Non-target driving status can be further subdivided into: smooth operation or stationary driving.

[0104] Because a vehicle's energy consumption varies under different driving conditions, when a vehicle is in its target driving state, such as climbing a hill or driving on a mountain road, its power consumption may increase rapidly in a short period, making it prone to battery depletion. When a vehicle is in a non-target driving state, such as driving on a flat road, its power consumption is relatively stable. Therefore, obtaining the vehicle's current driving state is crucial for accurately assessing its energy consumption.

[0105] In one feasible implementation, the vehicle's driving status can be determined by the vehicle's onboard terminal and sent to the onboard refrigerator, enabling the onboard refrigerator to obtain the vehicle's driving status for subsequent control. Alternatively, the vehicle's driving status can be determined directly by the onboard refrigerator acquiring data from sensors, processing the data, and then determining its status.

[0106] Step S120: If the vehicle is in the target driving state and the current energy consumption is greater than the set energy consumption, control the vehicle refrigerator to operate in energy-saving mode.

[0107] When a vehicle is in the target driving state, it indicates that the vehicle may be in a high energy consumption state. At this time, the comparison between the vehicle's current energy consumption and the set energy consumption can be used to determine whether the vehicle is in a high energy consumption state, thereby improving the accuracy of subsequent control.

[0108] In this embodiment, the vehicle refrigerator is controlled to operate in energy-saving mode when the vehicle is in a target driving state and the current energy consumption is greater than the set energy consumption. By combining the current target driving state of the vehicle with the judgment of the current energy consumption in that target driving state, the accuracy of the vehicle's energy consumption judgment is achieved. When the vehicle is in a high energy consumption state, although the energy consumption of the vehicle refrigerator, as an auxiliary electrical device in the vehicle, is relatively small, operating in energy-saving mode can further reduce its contribution to the overall energy consumption of the vehicle, which helps the vehicle to better manage energy consumption. This not only improves the control precision of the vehicle refrigerator, but also enables the vehicle to operate normally under high energy consumption conditions.

[0109] Reference Figure 5 In some embodiments of this application, obtaining the current driving status of the vehicle includes:

[0110] Step S111: Obtain the vehicle's tilt angle and acceleration.

[0111] The tilt angle of the vehicle is collected by a tilt sensor installed on the vehicle, and the acceleration of the vehicle is collected by an acceleration sensor installed on the vehicle. The collected tilt angle and acceleration are analyzed to obtain the driving status of the vehicle where the car refrigerator is located.

[0112] A tilt sensor is a sensor used to measure the tilt angle of a vehicle. It uses technologies such as gyroscopes or accelerometers to monitor the vehicle's tilt angle in real time, whether the vehicle is moving or stationary. When the vehicle is traveling on rough roads or engaging in off-road activities, i.e., when the vehicle is in its target driving state, the tilt sensor helps the driver or vehicle control system understand the vehicle's current state, thereby improving vehicle stability and safety. An accelerometer is used to measure changes in a vehicle's acceleration. It is often used in conjunction with the tilt sensor, reflecting the vehicle's vibration and tilt by detecting changes in acceleration in various directions. The accelerometer provides real-time acceleration data, helping the vehicle control system determine the vehicle's dynamic state and take appropriate measures to maintain stability.

[0113] Step S112: Determine the current driving state of the vehicle based on the tilt angle and acceleration.

[0114] In one feasible implementation, a mapping relationship between different tilt angles and accelerations and the vehicle's driving state can be pre-established, and the vehicle's driving state can be determined through this mapping relationship and the current vehicle tilt angle and acceleration.

[0115] In another feasible implementation, if the tilt angle is greater than or equal to a preset angle and the acceleration is greater than or equal to a preset acceleration, the vehicle is determined to be in the target driving state; if the tilt angle is less than a preset angle and the acceleration is less than a preset acceleration, the vehicle is determined to be in a non-target driving state.

[0116] In another feasible implementation, if the tilt angle is greater than or equal to a preset angle and the acceleration is greater than or equal to a preset acceleration for a first duration greater than a first preset duration, the vehicle is determined to be in a target driving state; if the tilt angle is less than a preset angle and the acceleration is less than a preset acceleration for a second duration greater than a second preset duration, the vehicle is determined to be in a non-target driving state. By determining that the vehicle is in a target driving state when the first duration is greater than the first preset duration, and determining that the vehicle is in a non-target driving state when the second duration is greater than the second preset duration, misjudgment of the vehicle's driving state can be avoided, and the accuracy of the vehicle's driving state determination can be improved.

[0117] The preset angle, preset acceleration, first preset duration, and second preset duration mentioned above can be set according to actual conditions.

[0118] In this embodiment, the vehicle's tilt angle and acceleration are obtained; based on the tilt angle and acceleration, the vehicle's driving state is determined, thereby improving the accuracy of the vehicle's driving state judgment.

[0119] In other embodiments, determining the driving status of the vehicle containing the in-vehicle refrigerator includes analyzing images acquired by image sensors installed on the vehicle to obtain the driving status of the vehicle. During image analysis and processing, a pre-trained large language model combined with corresponding prompt text can be used to analyze and process the images, thereby improving the processing efficiency of the vehicle's driving status and enabling rapid determination of the vehicle's driving status. Other methods can also be used to determine the driving status of the vehicle containing the in-vehicle refrigerator.

[0120] In other embodiments, the vehicle's current driving status can also be obtained; if the vehicle is in the target driving state and the current energy consumption is greater than the set energy consumption, the current operating mode of the vehicle refrigerator is obtained; the control parameters of the vehicle refrigerator under the operating mode are adjusted. Specifically, if the operating mode is cooling mode, at least one of the following is considered: increasing the vehicle refrigerator's start-up temperature, increasing the vehicle refrigerator's stop-loss temperature, and decreasing the vehicle refrigerator's compressor speed; or, if the operating mode is heating mode, at least one of the following is considered: decreasing the vehicle refrigerator's start-up temperature, decreasing the vehicle refrigerator's stop-loss temperature, and decreasing the vehicle refrigerator's compressor speed. After a preset time, if the current energy consumption is less than or equal to the set energy consumption, the vehicle refrigerator is controlled to operate according to the initial control parameters.
