[0030] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present application, however, it is obvious to those skilled in the art that the embodiments of the present application can be implemented without these specific details, and in other embodiments, the known structures and devices are shown in the form of block diagrams rather than in the form of details, to avoid making the embodiments of the present application difficult to understand.

[0031] The embodiments of the present application respectively propose a vehicle-mounted refrigerator control method, a vehicle-mounted refrigerator control device, a vehicle, an electronic device, a computer readable storage medium and a computer program product, which will be described in detail below.

[0032] Please refer to Figure 1 , Figure 1 is a schematic diagram of an implementation environment of a vehicle-mounted refrigerator control method according to an example embodiment of the present application.

[0033] As Figure 1 shown, the implementation environment can include a smart car 110 and a computer device 120, wherein the computer device 120 can be at least one of a microcomputer, an embedded computer, a neural network computer, etc., which is not limited here. The computer device 120 can be configured in the smart car 110, and the computer device 120 can also be a computer device independent of the smart car 110, which is also not limited here. The smart car 110 can obtain vehicle temperature information through a temperature sensor, a car system, etc., and provide it to the computer device 120 for processing, so that the computer device 120 determines the current vehicle-mounted refrigerator control strategy based on the vehicle temperature information.

[0034] Illustratively, vehicle temperature information is acquired, the vehicle temperature information including a vehicle air conditioner set temperature and an indoor return air temperature; a difference between the vehicle air conditioner set temperature and the indoor return air temperature is calculated as an actual temperature control error, and the actual temperature control error is compared with a preset temperature control error to determine a current vehicle refrigerator control strategy and execute the same, wherein the vehicle refrigerator control strategy includes a linkage control strategy. It can be seen that the technical solution of the embodiment of the present application can dynamically determine the current vehicle refrigerator control strategy by monitoring the difference between the vehicle air conditioner set temperature and the indoor return air temperature as the actual temperature control error and comparing the same with the preset temperature control error. Through the linkage control strategy, the vehicle refrigerator and the air conditioning system work cooperatively to ensure that the vehicle refrigerator achieves good refrigeration effect while reducing unnecessary repeated refrigeration, thereby effectively reducing overall energy consumption and achieving the purpose of energy saving and emission reduction.

[0035] It should be noted that the vehicle refrigerator control method provided by the embodiment of the present application is generally executed by the computer device 120, and accordingly, the vehicle refrigerator control apparatus is generally arranged in the computer device 120.

[0036] Please refer to Figure 2 , Figure 2 is a flowchart of a vehicle refrigerator control method according to an example embodiment of the present application. The vehicle refrigerator control method can be applied to Figure 1 the implementation environment shown in the figure and be executed by the computer device 120 in the implementation environment. It should be understood that the vehicle refrigerator control method can also be applied to other example implementation environments and be executed by devices in other implementation environments, and the embodiment does not limit the implementation environment to which the vehicle refrigerator control method is applied.

[0037] As shown in Figure 2 , in an example embodiment, the vehicle refrigerator control method at least includes steps S210 to S220, which are described in detail as follows:

[0038] Step S210, vehicle temperature information is acquired.

[0039] In an embodiment of the present application, the vehicle temperature information can be acquired in real time or periodically, wherein the vehicle temperature information comprises a vehicle air conditioner setting temperature and an indoor return air temperature. The vehicle air conditioner setting temperature can be acquired through a vehicle system (e.g., a center console) or a vehicle user mobile terminal (e.g., an automobile control application in a mobile phone), and the vehicle air conditioner setting temperature can be specifically a user setting temperature or a target temperature of an air outlet of the vehicle air conditioner system converted from the user setting temperature. For each user setting temperature, the air conditioner system can calibrate a fixed target temperature of the air outlet corresponding to the user setting temperature. The indoor return air temperature can be acquired by a temperature sensor arranged at the air outlet of the automobile air conditioner system (vehicle air conditioner system) to ensure the authenticity of the indoor temperature.

[0040] In step S220, the vehicle air conditioner setting temperature and the indoor return air temperature in the vehicle temperature information are subtracted to obtain an actual temperature control error, and the actual temperature control error is compared with a preset temperature control error to determine a current vehicle refrigerator control strategy and execute the current vehicle refrigerator control strategy.

[0041] In an embodiment of the present application, the vehicle refrigerator control strategy comprises a linkage control strategy. The linkage control strategy can be pre-set, and the linkage control strategy can be specifically to dynamically determine an output power according to the change of the vehicle air conditioner setting temperature and / or the indoor return air temperature, and control the vehicle refrigerator to operate according to the determined output power, wherein the lower the indoor return air temperature, the smaller the output power. The specific strategy of the linkage control strategy is not limited herein. Of course, the vehicle refrigerator control strategy can also comprise other control strategies.

[0042] Since the temperature control effect of the vehicle air conditioner is different in different scenarios, for example, when the vehicle air conditioner is just started, the temperature control error is large, and the temperature control effect has not reached an ideal state, and after the vehicle air conditioner is started for a period of time, the temperature control error is small, and the temperature control effect reaches an ideal state. Or whether the vehicle air conditioner is aging or has a fault, the refrigeration effect is also different. Therefore, after the vehicle air conditioner setting temperature and the indoor return air temperature are acquired, the difference between the vehicle air conditioner setting temperature and the indoor return air temperature can be calculated as an actual temperature control error, and the good or bad of the temperature control effect of the vehicle air conditioner can be judged according to the comparison result of the actual temperature control error and the preset temperature control error, so as to determine a suitable strategy as the current vehicle refrigerator control strategy, and control the operation of the vehicle refrigerator according to the current vehicle refrigerator control strategy, which can effectively ensure that the vehicle refrigerator reaches a good refrigeration effect.

[0043] The preset temperature control error can be specifically 5°C or 4°C, or other numerical values, which are not limited herein.

[0044] In an embodiment of the present application, the vehicle refrigerator control strategy further comprises an independent control strategy; the current vehicle refrigerator control strategy is determined by comparing the actual temperature control error with the preset temperature control error, comprising: if the actual temperature control error is greater than or equal to the preset temperature control error, the current vehicle refrigerator control strategy is the independent control strategy; if the actual temperature control error is less than the preset temperature control error, the current vehicle refrigerator control strategy is the linkage control strategy.

[0045] In this embodiment, the independent control strategy can be set in advance, and the independent control strategy can be to control the vehicle refrigerator to operate at a fixed output power, for example. The fixed output power can be the rated power of the vehicle refrigerator, or other power values, and the specific strategy of the independent control strategy is not limited herein. Good refrigeration effect of the vehicle refrigerator is a prerequisite for energy saving and consumption reduction. When the actual temperature control error is greater than or equal to the preset temperature control error, it indicates that the temperature control effect of the vehicle air conditioner is poor or has not yet reached the ideal state, and the independent control strategy is adopted to control the vehicle refrigerator, which can effectively ensure that the vehicle refrigerator achieves good refrigeration effect. When the actual temperature control error is less than the preset temperature control error, it indicates that the temperature control effect of the vehicle air conditioner is good or has reached the ideal state, and the linkage control strategy is adopted to control the vehicle refrigerator, which can reduce unnecessary repeated refrigeration on the basis of ensuring that the vehicle refrigerator achieves good refrigeration effect, thereby effectively reducing overall energy consumption and achieving the purpose of energy saving and emission reduction.

[0046] In an embodiment of the present application, the linkage control strategy comprises: calculating a difference between the temperature of the return air in the vehicle and the temperature of the heat dissipation port of the vehicle refrigerator as a heat dissipation temperature difference, wherein the vehicle temperature information further comprises the temperature of the heat dissipation port of the vehicle refrigerator; determining a target output power according to the temperature of the return air in the vehicle and the heat dissipation temperature difference, so as to control the vehicle refrigerator to operate at the target output power.

[0047] In this embodiment, a temperature sensor is pre-installed at the heat dissipation port of the vehicle refrigerator to collect the temperature of the heat dissipation port of the vehicle refrigerator, i.e., the temperature of the heat dissipation port of the vehicle refrigerator. The heat exchange of the vehicle refrigerator is to reduce the temperature inside the vehicle refrigerator by compressing and exchanging heat of the air (having a temperature equivalent to that of the vehicle interior) sucked into the vehicle refrigerator through the compressor inside the vehicle refrigerator. Therefore, the temperature of the return air in the vehicle and the heat dissipation temperature difference affect the refrigeration effect of the vehicle refrigerator, wherein, under the condition that the output power of the vehicle refrigerator is constant, the lower the temperature of the return air in the vehicle, the better the refrigeration effect of the vehicle refrigerator, and the smaller the heat dissipation temperature difference, the faster the heat dissipation of the vehicle refrigerator and the better the refrigeration effect. According to the influence of the temperature of the return air in the vehicle and the heat dissipation temperature difference on the refrigeration effect of the vehicle refrigerator, the target output power of the vehicle refrigerator is determined comprehensively in this embodiment, which can effectively avoid excessive refrigeration or insufficient refrigeration, thereby further improving energy utilization efficiency and reducing unnecessary energy consumption.

[0048] In an embodiment of the present application, the target output power is determined according to the temperature of the return air in the vehicle and the heat dissipation temperature difference, including: when the temperature of the return air in the vehicle is greater than or equal to a first preset temperature, and / or the heat dissipation temperature difference is greater than or equal to a first preset temperature difference, the target output power is the rated power of the vehicle-mounted refrigerator; when the temperature of the return air in the vehicle is less than the first preset temperature, and the heat dissipation temperature difference is less than the first preset temperature difference, the target output power is calculated according to the rated power and a target power reduction, wherein the target power reduction is determined based on the temperature of the return air in the vehicle and the heat dissipation temperature difference.

[0049] In this embodiment, the first preset temperature, the first preset temperature difference and the preset power reduction can be set in advance, wherein the first preset temperature can be 30℃ or 31℃, or other temperature values, the first preset temperature difference can be 11℃ or 12℃, or other temperature values, which are not limited here.

[0050] Taking the first preset temperature as 30℃ and the first preset temperature difference as 12℃ as an example, if the temperature of the return air in the vehicle is ≥30℃, and / or the heat dissipation temperature difference is ≥12℃, the target output power is the rated power, if the temperature of the return air in the vehicle is <30℃, and the heat dissipation temperature difference is <12℃, the power is reduced based on the rated power according to the target power reduction to obtain the target output power. This embodiment reduces the output power of the vehicle-mounted refrigerator when the temperature in the vehicle drops to a certain range, reaches comfort, and the heat dissipation port of the vehicle-mounted refrigerator dissipates heat quickly, which can not only ensure user comfort, but also reduce energy consumption, and comprehensively improve user experience.

[0051] Generally, the rated power of the vehicle-mounted refrigerator is 40W-50W.

[0052] In an embodiment of the present application, the target output power is calculated according to the rated power and the target power reduction, including: comparing the return air temperature in the vehicle and the heat dissipation temperature difference with a plurality of preset conditions, determining the target preset condition satisfied by the return air temperature in the vehicle and the heat dissipation temperature difference, calculating the difference between the rated power and the target power reduction corresponding to the target preset condition as the target output power; wherein each preset condition has a corresponding power reduction, and the plurality of preset conditions include a first preset condition, a second preset condition and a third preset condition, the power reduction corresponding to the first preset condition is less than the power reduction corresponding to the second preset condition, and the power reduction corresponding to the second preset condition is less than the power reduction corresponding to the third preset condition; the first preset condition includes that the return air temperature in the vehicle is greater than or equal to a second preset temperature and less than a first preset temperature, and the heat dissipation temperature difference is less than a first preset temperature difference; or, the return air temperature in the vehicle is greater than or equal to a third preset temperature and less than the second preset temperature, and the heat dissipation temperature difference is greater than or equal to a second preset temperature difference and less than the first preset temperature difference; the second preset condition includes that the return air temperature in the vehicle is greater than or equal to the third preset temperature and less than the second preset temperature, and the heat dissipation temperature difference is less than the second preset temperature difference; or, the return air temperature in the vehicle is less than the third preset temperature, and the heat dissipation temperature difference is greater than or equal to a third preset temperature difference and less than the first preset temperature difference; the third preset condition includes that the return air temperature in the vehicle is less than the third preset temperature, and the heat dissipation temperature difference is less than the third preset temperature; the second preset temperature is less than the first preset temperature, the third preset temperature is less than the second preset temperature, the second preset temperature difference is less than the first preset temperature difference, and the third preset temperature difference is less than the second preset temperature difference.

[0053] In this embodiment, the lower the return air temperature in the vehicle and / or the smaller the heat dissipation temperature difference, the faster the refrigeration speed and the better the refrigeration effect, so different return air temperature ranges in the vehicle and different heat dissipation temperature difference ranges can be pre-divided as preset conditions of different gradient power reductions, and when the return air temperature in the vehicle and the heat dissipation temperature difference satisfy which preset condition, the rated power is reduced according to the power reduction corresponding to the preset condition to obtain the target output power.

[0054] Illustratively, the second preset temperature can be 25℃ or 26℃, or any other value less than the first preset temperature, the third preset temperature can be 19℃ or 20℃, or any other value less than the second preset temperature, the second preset temperature difference can be 9℃ or 10℃, or any other value less than the first preset temperature difference, the third preset temperature difference can be 6℃ or 8℃, or any other value less than the second preset temperature difference, the power reduction corresponding to the first preset condition can be 4W or 5W, or any other value, the power reduction corresponding to the second preset condition can be 9W or 10W, or any other value greater than the power reduction corresponding to the first preset condition, the power reduction corresponding to the third preset condition can be 14W or 15W, or any other value greater than the power reduction corresponding to the second preset condition, which are not limited here.

[0055] Please refer to Table 1, which is a linkage control strategy table shown in a specific embodiment of the present application. As shown in Table 1, H1 is the temperature of the return air in the vehicle, S1 is the temperature of the heat dissipation port of the vehicle-mounted refrigerator, S1-H1 is the heat dissipation temperature difference, P is the rated power of the vehicle-mounted refrigerator, the first preset temperature is 30℃, the second preset temperature is 25℃, the third preset temperature is 20℃, the first preset temperature difference is 12℃, the second preset temperature difference is 10℃, the third preset temperature difference is 8℃, the power reduction corresponding to the first preset condition is 5W, the power reduction corresponding to the second preset condition is 10W, and the power reduction corresponding to the third preset condition is 15W. The first preset condition includes:

[0056] 25℃≤H1<30℃ and S1-H1<12℃

[0057] or,

[0058] 20℃≤H1<25℃ and 10℃≤S1-H1<12℃

[0059] The second preset condition includes:

[0060] 20℃≤H1<25℃ and S1-H1<10℃

[0061] or,

[0062] H1<20℃ and 8℃≤S1-H1<12℃

[0063] The third preset condition includes:

[0064] H1<20℃ and S1-H1<8℃

[0065] In the current vehicle refrigerator control strategy, when the linkage control strategy is used, if the temperature difference between the return air temperature in the vehicle and the heat dissipation temperature satisfies a first preset condition, the vehicle refrigerator is controlled to operate according to a target output power that is 5 W less than the rated power, if the temperature difference between the return air temperature in the vehicle and the heat dissipation temperature satisfies a second preset condition, the vehicle refrigerator is controlled to operate according to a target output power that is 10 W less than the rated power, and if the temperature difference between the return air temperature in the vehicle and the heat dissipation temperature satisfies a third preset condition, the vehicle refrigerator is controlled to operate according to a target output power that is 15 W less than the rated power, which can effectively reduce the energy consumption. Taking the temperature 25℃ with higher comfort in the vehicle as a benchmark for estimation, if the power of the compressor of the vehicle refrigerator is reduced by 10 W, 0.1 degree of electricity can be saved every 10 hours through conversion.

[0067]

[0068] In another embodiment of the present application, the target output power is calculated according to the rated power and the target power reduction, including: determining the power reduction corresponding to the return air temperature in the vehicle based on the return air temperature in the vehicle and a preset corresponding relationship between the return air temperature in the vehicle and the power reduction, and determining the power reduction corresponding to the heat dissipation temperature difference based on the heat dissipation temperature difference and a preset corresponding relationship between the heat dissipation temperature difference and the power reduction; determining the target power reduction according to the power reduction corresponding to the return air temperature in the vehicle and the power reduction corresponding to the heat dissipation temperature difference, and calculating the difference between the rated power and the target power reduction as the target output power.

[0069] In this embodiment, the correspondence between the return air temperature in the vehicle and the power reduction range, and the correspondence between the heat dissipation temperature difference and the power reduction range can be determined by experimental tests in advance, respectively. The correspondence can be a corresponding table or a functional relationship, which is not limited here. The lower the return air temperature in the vehicle, the greater the power reduction range; the smaller the heat dissipation temperature difference, the greater the power reduction range. The return air temperature in the vehicle and the heat dissipation temperature difference are respectively substituted into the respective corresponding relationships to obtain the power reduction range corresponding to the return air temperature in the vehicle and the power reduction range corresponding to the heat dissipation temperature difference. Then, the minimum value of the power reduction range corresponding to the return air temperature in the vehicle and the power reduction range corresponding to the heat dissipation temperature difference can be selected as the target power reduction range, and the difference between the rated power and the target power reduction range is taken as the target output power, so as to preferentially ensure the refrigeration effect of the vehicle-mounted refrigerator. The average or weighted average of the power reduction range corresponding to the return air temperature in the vehicle and the power reduction range corresponding to the heat dissipation temperature difference can also be taken as the target power reduction range. Through the average or weighted average, a balance point can be found between ensuring the refrigeration effect of the vehicle-mounted refrigerator and saving energy, that is, neither the energy is excessively consumed to pursue excellent refrigeration effect, nor the refrigeration speed or effect of the vehicle-mounted refrigerator is reduced due to significant energy saving. In addition, the weighted average method can also adjust the weight of different factors according to actual needs. For example, when the return air temperature in the vehicle is low but the heat dissipation temperature difference is large, such as when the return air temperature in the vehicle is lower than 20℃ and the heat dissipation temperature difference is higher than 10℃, the weight of the power reduction range corresponding to the heat dissipation temperature difference can be increased, and when the return air temperature in the vehicle is high but the heat dissipation temperature difference is small, such as when the return air temperature in the vehicle is higher than 25℃ and the heat dissipation temperature difference is lower than 8℃, the weight of the power reduction range corresponding to the return air temperature in the vehicle can be increased, so as to preferentially ensure the refrigeration effect of the vehicle-mounted refrigerator.

[0070] In an embodiment of the present application, if the set temperature of the vehicle-mounted air conditioner and the return air temperature in the vehicle change, causing the comparison result of the actual temperature control error and the preset temperature control error to change, the current control strategy of the vehicle-mounted refrigerator is switched to control the vehicle-mounted refrigerator.

[0071] In this embodiment, the vehicle air conditioner setting temperature and the indoor return air temperature are monitored to determine the actual temperature control error in real time according to the vehicle air conditioner setting temperature and the indoor return air temperature. When at least one of the vehicle air conditioner setting temperature and the indoor return air temperature changes, causing the comparison result of the actual temperature control error and the preset temperature control error to change, the current vehicle refrigerator control strategy is switched, and the operation of the vehicle refrigerator is controlled, including: if the actual temperature control error changes from greater than or equal to the preset temperature control error to less than the preset temperature control error, the current vehicle refrigerator control strategy is switched from the independent control strategy to the linkage control strategy; if the actual temperature control error changes from less than the preset temperature control error to greater than or equal to the preset temperature control error, the current vehicle refrigerator control strategy is switched from the linkage control strategy to the independent control strategy. The current vehicle refrigerator control strategy can be flexibly switched according to the change of the temperature control effect of the vehicle air conditioner, energy saving and consumption reduction are realized based on the priority to ensure that the vehicle refrigerator achieves good refrigeration effect, and user experience is improved.

[0072] Please refer to Figure 3 , Figure 3 is a block diagram of a vehicle refrigerator control device according to an example embodiment of the present application.
