Temperature control method, device and vehicle
[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 8, 2023, with application number 202311692546.3 and application name “Temperature Control Method, Device and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field
[0002] The present application relates to the field of intelligent driving, and in particular to a temperature control method, device and vehicle. Background Art
[0003] With the rapid development of the transportation industry, more and more vehicles are equipped with onboard refrigerators to meet users' needs for refrigerated and fresh food, improving the comfort and safety of outdoor travel. Currently, there are two main types of onboard refrigerators: compressor refrigerators, which offer high cooling efficiency but slow response, heavy weight, and high cost. Semiconductor refrigerators, on the other hand, offer fast response, light weight, and low cost, but lower cooling efficiency.
[0004] Therefore, how to optimize temperature control and achieve efficient operation of car refrigerators at low cost has become a technical problem that needs to be solved urgently.
[0005] Summary of the Invention
[0006] The embodiments of the present application provide a temperature control method, device, and vehicle, which can achieve efficient operation of a vehicle refrigerator at low cost.
[0007] In order to achieve the above objectives, the embodiments of the present application provide the following technical solutions:
[0008] In a first aspect, an embodiment of the present application provides a temperature control method, which includes: obtaining the working status of a first device in a vehicle, the working status including a cooling state and a heating state; obtaining the temperature in the vehicle; when the temperature in the vehicle is greater than a first temperature threshold and the working status of the first device is a cooling state, operating a second device in the vehicle to lower the temperature in the vehicle; or, when the temperature in the vehicle is less than a second temperature threshold and the working status of the first device is a heating state, operating the second device in the vehicle to increase the temperature in the vehicle.
[0009] In this way, depending on the operating state of the first device, when the interior temperature of the vehicle affects the efficiency of the first device in that operating state, the second device adjusts the interior temperature to enable the first device to operate more efficiently. By linking the first and second devices to control the interior temperature, the car refrigerator can be operated efficiently and cost-effectively, ensuring normal use in different ambient temperatures and expanding the use cases of the car refrigerator.
[0010] According to the first aspect, the first device is a vehicle-mounted refrigerator, and the second device is a vehicle-mounted air conditioner.
[0011] In some examples, the first device is a semiconductor vehicle refrigerator that provides refrigeration or heat preservation functions in a vehicle.
[0012] According to the first aspect, or any implementation of the first aspect above, the working status of the first device is obtained through various sensors installed on the vehicle.
[0013] According to the first aspect, or any implementation of the first aspect above, the operating status of the first device is obtained from various subsystems of the vehicle.
[0014] According to the first aspect, or any implementation of the first aspect above, before obtaining the working status of the first device in the vehicle, the method also includes: receiving a first signal sent by a remote device, the first signal being used to indicate that the first device is started; starting the first device according to the working status indicated by the first signal; or obtaining the working status adopted by the first device when it was last run; and running the first device according to the working status adopted when it was last run.
[0015] In some examples, in response to a user's operation of starting a first device in a vehicle, the working status or preset data or user-set data used when the first device was last run is obtained, and the first device is started and operated according to the working status or preset data or user-set data used when the first device was last run.
[0016] In some examples, the temperature inside the vehicle is obtained in real time through a temperature sensor installed on the vehicle.
[0017] In other examples, the interior temperature of the vehicle is obtained from various subsystems of the vehicle.
[0018] In this way, the interior temperature of the vehicle is obtained in real time according to the real-time working status of the first device, so as to subsequently accurately determine whether the interior temperature affects the working efficiency of the first device.
[0019] In some examples, the first temperature threshold is a predetermined maximum temperature threshold at which the first device can perform cooling operation without reducing cooling efficiency.
[0020] In other examples, the second temperature threshold is a predetermined minimum temperature threshold at which the first device can perform heating operation without reducing heating efficiency.
[0021] In this way, corresponding temperature thresholds are pre-set for different working states of the first device, so as to quickly determine whether the temperature inside the vehicle affects the current working state of the first device, so as to accurately control the temperature subsequently, so that the first device can continue to work with higher working efficiency and improve the refrigeration or insulation effect.
[0022] According to the first aspect, or any implementation of the first aspect above, running the second device in the vehicle to lower the temperature inside the vehicle includes: when the second device is not started, starting the second device, and running the second device according to the first temperature setting value to lower the temperature inside the vehicle.
[0023] According to the first aspect, or any implementation of the first aspect above, operating the second device in the vehicle to lower the temperature in the vehicle includes: when the second device is started, operating the second device according to the second temperature setting value to lower the temperature in the vehicle.
[0024] In some examples, the first temperature setting value and the second temperature setting value are both less than or equal to the first temperature threshold, and the second temperature setting value may be the same as or different from the first temperature setting value.
[0025] In this way, when the first device is in cooling mode and the vehicle interior temperature is above a first temperature threshold, the second device is activated to lower the vehicle interior temperature to a level at which the first device's operating efficiency is not affected when in cooling mode. Even if the first device is in a high-temperature environment, the second device can lower the ambient temperature, ensuring the first device's high efficiency and meeting diverse user needs.
[0026] According to the first aspect, or any implementation of the first aspect above, operating the second device in the vehicle to increase the temperature inside the vehicle includes: when the second device is not started, starting the second device, and operating the second device according to the third temperature setting value to increase the temperature inside the vehicle.
[0027] According to the first aspect, or any implementation of the first aspect above, when the second device is started, the second device is operated according to the fourth temperature setting value to increase the temperature inside the vehicle.
[0028] In some examples, the third temperature setting value and the fourth temperature setting value are both greater than or equal to the second temperature threshold, and the third temperature setting value may be the same as or different from the fourth temperature setting value.
[0029] In this way, when the first device is operating in heating mode and the vehicle interior temperature is below the second temperature threshold, the second device is activated to raise the vehicle interior temperature to a level at which the first device's heating mode does not affect its efficiency. Even if the first device is in a low-temperature environment, the second device can still raise the ambient temperature, ensuring the first device's high efficiency and meeting diverse user needs.
[0030] In a possible implementation, when the temperature inside the vehicle is greater than a first temperature threshold or the temperature inside the vehicle is less than a second temperature threshold, the method further includes: prompting the user in a preset manner to adjust the temperature inside the vehicle through a second device.
[0031] In this way, when the temperature inside the car is greater than the first temperature threshold or the temperature inside the car is less than the second temperature threshold, the user can be prompted to improve the temperature inside the car in a variety of ways. The user can customize the setting of the second device, which is conducive to providing a comfortable riding environment and increasing riding comfort and safety.
[0032] According to the first aspect, or any implementation of the first aspect above, the method further includes: turning off the second device after a preset time period.
[0033] According to the first aspect, or any implementation of the first aspect above, after running the second device in the vehicle to lower the temperature inside the vehicle, the method also includes: automatically turning off the second device when the temperature inside the vehicle is less than or equal to a third temperature threshold; wherein the third temperature threshold is less than or equal to the first temperature threshold.
[0034] In some examples, the third temperature threshold is less than or equal to the first temperature threshold.
[0035] In this way, when the second device is operating as a cooling system, the temperature inside the vehicle gradually decreases. When the temperature inside the vehicle is less than or equal to the third temperature threshold, the temperature inside the vehicle meets the efficient cooling requirements of the first device, and the second device is automatically shut down, preventing the second device from running for a long time and consuming excessive power, thus saving energy and resources. Furthermore, when the third temperature threshold is lower than the first temperature threshold, there is a gap between the third temperature threshold and the first temperature threshold, which can prevent the second device from being frequently activated, extending the interval between the second device's use, reducing power consumption, and further saving energy.
[0036] According to the first aspect, or any implementation of the first aspect above, after running the second device in the vehicle to increase the temperature inside the vehicle, the method also includes: automatically turning off the second device when the temperature inside the vehicle is greater than or equal to a fourth temperature threshold; wherein the fourth temperature threshold is greater than or equal to the second temperature threshold.
[0037] In some examples, the fourth temperature threshold is greater than or equal to the second temperature threshold.
[0038] In this way, when the second device is operating as a heating device, the interior temperature gradually increases. When the interior temperature is greater than or equal to the fourth temperature threshold, the interior temperature meets the requirements of efficient heating by the first device, and the second device is automatically shut down, preventing the second device from running for a long time and consuming excessive power, thus saving energy and resources. Furthermore, when the fourth temperature threshold is greater than the second temperature threshold, there is a gap between the fourth temperature threshold and the second temperature threshold, which can prevent the second device from being frequently activated, extending the interval between the second device's use, reducing power consumption, and further saving energy.
[0039] According to the first aspect, or any implementation of the first aspect above, after running the second device in the vehicle to lower the temperature inside the vehicle, the method also includes: when the temperature inside the vehicle is less than or equal to the first temperature threshold, obtaining the temperature outside the vehicle; if the temperature outside the vehicle is less than or equal to the first temperature threshold, setting the state of the second device to the external circulation state.
[0040] According to the first aspect, or any implementation of the first aspect above, after running the second device in the vehicle to increase the temperature inside the vehicle, the method also includes: when the temperature inside the vehicle is greater than or equal to the second temperature threshold, obtaining the temperature outside the vehicle; if the temperature outside the vehicle is greater than or equal to the second temperature threshold, setting the second device to the external circulation state.
[0041] In some examples, when the temperature inside the vehicle drops to or below a first temperature threshold, and if the outside temperature does not exceed the first temperature threshold, the cooling function of the second device is turned off and the external circulation state is activated. Alternatively, when the temperature inside the vehicle rises to or above a second temperature threshold, and if the outside temperature does not fall below the second temperature threshold, the heating function of the second device is turned off and the external circulation state is activated. This maintains the temperature inside the vehicle, ensuring the efficient operation of the first device, while also introducing fresh air into the vehicle, improving user comfort and saving power.
[0042] According to the first aspect, or any implementation of the first aspect above, the method further includes: when the vehicle power level is less than a preset power threshold, turning off the first device and / or the second device.
[0043] In this way, it is avoided that the first device and / or the second device consumes too much power due to long-term operation, which causes the vehicle to be unable to drive normally.
[0044] In a second aspect, embodiments of the present application provide a temperature control device. The temperature control device includes a processor and a memory, wherein the memory is coupled to the processor and is configured to store computer-readable instructions. When the processor reads the computer-readable instructions from the memory, the data acquisition device executes the method according to the first aspect and any one of the embodiments of the first aspect.
[0045] In a third aspect, an embodiment of the present application provides a vehicle comprising the temperature control device provided in the second aspect.
[0046] Optionally, the transportation vehicle includes a vehicle, such as an electric car, a car, a truck, a motorcycle, a bus, a lawn mower, an amusement vehicle, an amusement park vehicle, construction equipment, a tram, a golf cart, a train, and a cart, etc., which is not particularly limited in the embodiments of the present application.

[0056] In the description of the embodiments of the present application, unless otherwise specified, “ / ” means or, for example, A / B can mean A or B; “and / or” in this article is merely a way to describe the association relationship of associated objects, indicating that three relationships can exist, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.
[0057] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.
[0058] In the description of the embodiments of the present application, unless otherwise specified, "multiple" means two or more. In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or design. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete way.
[0059] In some examples, car refrigerators can use compressors to achieve cooling and heat preservation functions. Specifically, based on the compressor cycle principle, temperature regulation is achieved by compressing and expanding the refrigerant, and cooling or heating is achieved by changing the pressure and temperature. Compressor car refrigerators have high cooling efficiency and are not affected by the environment, but they are heavy and costly. For example, after a compressor car refrigerator is operated continuously for two hours at any temperature within the ambient temperature range of 30℃-35℃, the internal temperature of the compressor car refrigerator drops by an average of 8.5℃.
[0060] In other examples, car refrigerators can also use semiconductors to achieve cooling and heat preservation functions. Specifically, based on the Peltier effect, temperature regulation is achieved by passing electric current in semiconductor materials, and cooling or heating is achieved by changing the direction of the current. The cooling efficiency of semiconductor car refrigerators is affected by the surrounding environment. The higher the ambient temperature, the worse the cooling efficiency, but they are light in weight and low in cost. For example, after a semiconductor car refrigerator has been working continuously for two hours at an ambient temperature of 30°C, the internal temperature of the semiconductor car refrigerator has dropped by an average of 9.2°C. However, after a semiconductor car refrigerator has been working continuously for two hours at an ambient temperature of 35°C, the internal temperature of the semiconductor car refrigerator has dropped by an average of 5.8°C.
[0061] In order to solve the technical problems mentioned above, an embodiment of the present application provides a temperature control method, which obtains the working state of a first device in the car, and the working state includes a cooling state and a heating state; obtains the temperature in the car; when the temperature in the car is greater than a first temperature threshold and the working state of the first device is a cooling state, runs the second device in the car to lower the temperature in the car; or, when the temperature in the car is less than a second temperature threshold and the working state of the first device is a heating state, runs the second device in the car to increase the temperature in the car. The solution of the embodiment of the present application, according to the working state of the first device, when the temperature in the car affects the efficiency of the first device in this working state, the temperature in the car is regulated by the second device so that the first device works efficiently. The method provided by the embodiment of the present application can achieve efficient operation of the car refrigerator at a low cost, ensure the normal use of the car refrigerator under different ambient temperatures, and increase the use scenarios of the car refrigerator.
[0062] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.
[0063] The temperature control method in the embodiments of the present application can be applied to various devices using a vehicle refrigerator (also described as the first device) and a vehicle air conditioner (also described as the second device). The various devices may include various transportation vehicles such as new energy vehicles, electric vehicles, buses, and cars. The embodiments of the present application do not impose any particular restrictions on the specific form of the device.
[0064] Referring to Figure 1 , a temperature control system 10 according to an embodiment of the present application is shown. As shown in Figure 1 , the temperature control system 10 includes a first device 11, an acquisition module 12, a temperature control device 13, and a second device 14. The first device 11, the temperature acquisition module 12, the temperature control device 13, and the second device 14 are connected and in communication with each other.
[0065] The first device 11 is a vehicle refrigerator that provides cooling or heat preservation functions. The first device 11 is a semiconductor vehicle refrigerator. The first device 11 operates in two modes: cooling and heating. For example, when the first device 11 is in the cooling mode, the first device 11 is used to keep food refrigerated. When the first device 11 is in the heating mode, the first device 11 is used to keep food warm.
[0066] The acquisition module 12 can be used to acquire the working status of the first device in the vehicle, the acquisition module 12 can also be used to acquire the temperature in the vehicle, and the acquisition module 12 can also be used to report the acquired working status of the first device and the temperature in the vehicle to the temperature control device 13.
[0067] The acquisition module 12 includes a vehicle sensor, which is typically located inside the vehicle. The vehicle sensor can be used to detect the operating status of the first device and the temperature inside the vehicle. The vehicle sensor can be any of a temperature sensor, a photoelectric speed sensor, a magnetoelectric speed sensor, and a Hall effect speed sensor, without limitation.
[0068] It can be understood that since the vehicle sensor is set in the vehicle, when the acquisition module 12 is a vehicle sensor, the acquisition module 12 moves with the vehicle, and the acquisition module 12, the first device 11 and the temperature control device 13 can communicate through the wireless communication network.
[0069] It should be understood that the above description of the acquisition module 12 is merely an example, and the embodiment of the present application does not specifically limit the specific form and implementation of the acquisition module 12.
[0070] Referring to FIG. 1 , the temperature control device 13 shown in FIG. 1 can be configured to, based on the operating status of the first device in the vehicle and the vehicle interior temperature received from the acquisition module 12 , interact with the second device 14 to control the operation of the second device to lower the vehicle interior temperature when the temperature control device 13 determines that the vehicle interior temperature is greater than a first temperature threshold and the operating status of the first device is cooling. Alternatively, when the temperature control device 13 determines that the vehicle interior temperature is less than a second temperature threshold and the operating status of the first device is heating, interact with the second device 14 to control the operation of the second device 14 to raise the vehicle interior temperature.
[0071] In other examples, the temperature control device 13 obtains the working status of the first device from the first device 11, and obtains the vehicle interior temperature from the obtaining module 12. The embodiment of the present application does not limit the specific implementation method of the temperature control device 13 obtaining the working status of the first device and the vehicle interior temperature.
[0072] Optionally, the temperature control device 13 may be a server. As an example, the temperature control device 13 may be a server of an intelligent transportation system, such as a physical server or a cloud server, which is not limited in this embodiment of the present application.
[0073] Alternatively, the temperature control device 13 may be an intelligent driving computing platform. This platform implements intelligent driving, decision-making, planning, and control functions and is a core component of the vehicle. The platform interacts with various components in the vehicle, acquiring real-time data from each component and controlling its operation.
[0074] The second device 14 is an onboard air conditioner for adjusting the temperature inside the vehicle. The second device 14 interacts with the temperature control device 13 and lowers or raises the temperature inside the vehicle according to the control of the temperature control device 13.
[0075] It is understandable that in the above example, the first device 11, the acquisition module 12, the temperature control device 13, and the second device 14 in the temperature control system 10 are independent components, and the first device 11, the acquisition module 12, the temperature control device 13, and the second device 14 exchange data to complete temperature control. In actual applications, the acquisition module 12 and the temperature control device 13 can be deployed on the same component. For example, if the temperature control device 13 is an intelligent driving computing platform, the acquisition module 12 is deployed on the temperature control device 13. The temperature control device 13 integrates the acquisition module 12, interacts with the first device 11 and the second device 14, and realizes data collection and temperature control. The embodiment of the present application does not limit the temperature control system.
[0076] The various modules in the above-mentioned temperature control system are divided according to functional logic, and may actually be divided in other ways. In addition, the above-mentioned modules can be named by other names. In addition, each module can be implemented by hardware, or by software, or by a combination of hardware and software. Whether a specific module is implemented by hardware, software, or a combination of hardware and software depends on the specific application and design constraints of the technical solution. Different modules can be implemented by different hardware, and multiple modules can also be implemented by the same hardware. The embodiments of the present application do not specifically limit this.

The memory 22 may also include a combination of the aforementioned types of memory.
[0081] In one possible implementation, the memory 22 may exist independently of the processor 21. The memory 22 may be connected to the processor 21 via a bus 24 and used to store data, instructions, or program codes. When the processor 21 calls and executes the instructions or program codes stored in the memory 22, the temperature control method provided in the embodiment of the present application can be implemented.
[0082] In another possible implementation, the memory 22 may also be integrated with the processor 21 .
[0083] The communication interface 23 is used to connect the temperature control device 13 to other devices (such as the first device 11, the acquisition module 12, and the second device 14) via a communication network. The communication network can be a transceiver circuit, Ethernet, a radio access network (RAN), a wireless local area network (WLAN), etc. The communication interface 23 can include a receiving unit for receiving data and a transmitting unit for sending data.
[0084] Bus 24 can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus. This bus can be divided into an address bus, a data bus, a control bus, etc. For ease of illustration, FIG2 shows only one thick line, but this does not mean that there is only one bus or only one type of bus.
[0085] It should be pointed out that the structure shown in FIG2 does not constitute a limitation on the temperature control device 13. In addition to the components shown in FIG2, the temperature control device 13 may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0096] Processor 361 may be any conventional processor, such as a commercially available central processing unit (CPU).
[0097] In some embodiments, memory 362 may include instructions 3621 (e.g., program logic) that are executable by processor 361 to perform various functions of vehicle 300. Memory 362 may also include additional instructions, including instructions for sending data to, receiving data from, interacting with, and / or controlling one or more of travel system 310, sensor system 320, control system 330, and peripherals 340.
[0098] In addition to instructions 3621, memory 362 may also store data such as road maps, route information, the vehicle's location, direction, speed, and other vehicle data, and other information. This information may be used by vehicle 300 and computer system 360 during operation of vehicle 300 in autonomous, semi-autonomous, and / or manual modes.
[0099] The user interface 370 is used to provide information to or receive information from a user of the vehicle 300 .
[0100] Computer system 360 may control functions of vehicle 300 based on input received from various subsystems (e.g., travel system 310, sensor system 320, and control system 330) and from user interface 370. In some embodiments, computer system 360 may provide control over many aspects of vehicle 300 and its subsystems.
[0101] In some embodiments, the vehicle 300 may also include a vehicle controller (not shown in FIG3 ), which can also be described as a powertrain controller or an intelligent driving computing platform. It is the core control component of the entire vehicle. It collects input information from various systems and components, and after making corresponding judgments based on the above input information, controls the operation of various components in the vehicle 300 and drives the vehicle 300. Specifically, as the command and management center of the vehicle 300, the main functions of the vehicle controller include: driving torque control, optimized control of braking energy, energy management of the entire vehicle, maintenance and management of the controller area network (CAN), fault diagnosis and processing, and vehicle status monitoring. It plays a role in controlling the operation of the vehicle. Therefore, the quality of the vehicle controller directly determines the stability and safety of the vehicle.
[0102] Alternatively, one or more of the above components may be installed or associated separately from the vehicle 300. For example, the memory 362 may be partially or completely separate from the vehicle 300. The above components may be communicatively coupled together in a wired and / or wireless manner.
[0103] Optionally, the above components are only an example. In actual applications, the components in the above modules may be added or deleted according to actual needs. Figure 3 should not be understood as a limitation on the embodiments of the present application.
[0104] The vehicle 300 may be a new energy vehicle, an electric vehicle, a sedan, a car, a truck, a motorcycle, a bus, a boat, an airplane, a helicopter, a lawn mower, an amusement vehicle, an amusement park vehicle, construction equipment, a tram, a golf cart, or a train, etc., and is not particularly limited in this embodiment of the present application. The vehicle may be powered by gasoline, diesel, electricity, solar energy, hydrogen energy, or the like.
[0105] In other embodiments of the present application, the vehicle may further include hardware structures and / or software modules to implement the aforementioned functions in the form of hardware structures, software modules, or a combination of hardware structures and software modules. Whether a particular one of the aforementioned functions is implemented in the form of hardware structures, software modules, or a combination of hardware structures and software modules depends on the specific application and design constraints of the technical solution.
[0106] The method provided in the embodiments of the present application is described below with reference to the accompanying drawings.
[0107] To improve the operating efficiency of a vehicle refrigerator while ensuring low cost, this application proposes a temperature control method that can be applied to various devices using a vehicle refrigerator (hereinafter referred to as a first device) and a vehicle air conditioner (hereinafter referred to as a second device), such as vehicle 300 shown in FIG3 . The method can be executed by the vehicle or other devices outside the vehicle, or by a processor on the vehicle or other devices outside the vehicle, such as processor 21 and processor 361 mentioned above.
[0108] The present application embodiment is introduced by taking a new energy vehicle as an example. Referring to FIG4 , FIG4 shows a flow chart of a temperature control method provided by the present application embodiment. The temperature control method includes the following steps S401 to S404:
[0109] S401: The vehicle controller obtains the working state of a first device in the vehicle, where the working state includes a cooling state and a heating state.
[0110] In an embodiment of the present application, the vehicle controller is the core control component of the vehicle. The vehicle controller obtains the working status of the first device in the vehicle, and makes corresponding judgments and decisions based on the working status of the first device. Based on the above decisions, the operation of each component in the vehicle is controlled (such as controlling the operation of the second device), thereby adjusting the temperature inside the vehicle.
[0111] In the embodiment of the present application, the first device is a vehicle refrigerator that provides cooling or heat preservation functions in a vehicle. The first device is a semiconductor vehicle refrigerator.
[0112] In the embodiments of the present application, the state of the first device includes an operating state and a non-operating state. The operating state is a state in which the first device is enabled and in operation, providing a cooling or heating function. The non-operating state is a state in which the first device is not enabled, which can also be understood as the first device being powered off or not operating.
[0113] The working state includes a cooling state and a heating state. When the working state of the first device is the cooling state, the first device provides a refrigeration function. When the working state of the first device is the heating state, the first device provides a heat preservation function.
[0114] It is understandable that the first device can only be in one working state when working, and cannot be in two working states at the same time.
[0115] Optionally, the operating status of the first device in the vehicle may be indicated by a flag.
[0116] In some examples, a flag is set for the operating state of the first device, and the operating state of the first device in the vehicle is represented by the flag value. For example, if the operating state of the first device is 1, it indicates that the first device is in the cooling state. If the operating state of the first device is 2, it indicates that the first device is in the heating state. If the state of the first device is 0, it indicates that the first device is in the Wei Gongzi state. The embodiments of the present application do not specifically limit the specific method of representing the operating state of the first device.
[0117] In some embodiments of the present application, the vehicle controller obtains the working status of the first device through various sensors installed on the vehicle.
[0118] In some other embodiments of the present application, the vehicle controller obtains the operating status of the first device from various subsystems of the vehicle. For example, in the example of vehicle 300 described above, the vehicle controller obtains the operating status of the first device from the refrigerator 345 of the vehicle 300 .
[0119] It can be understood that, in the embodiment of the present application, before the vehicle controller obtains the working status of the first device in the vehicle, the first device has been started and operated in the vehicle.
[0120] In a possible implementation, the vehicle controller starts the first device in response to a user operation.
[0121] In some examples, the vehicle controller responds to a user's operation of starting a first device in a vehicle (such as the user clicking a function button of the first device to start the first device), and the vehicle controller obtains the working status or preset data or user-set data used when the first device was last run, and the vehicle controller starts running the first device according to the working status or preset data or user-set data used when the first device was last run.
[0122] It is understandable that the vehicle controller can store the working status and related data of the first device before it is shut down each time. For example, the working status of the first device when it was last run was the cooling status, and the cooling temperature was 26°C. When the vehicle controller responds to the user's operation and starts the first device again, it starts the first device according to the stored historical data of the cooling status and the cooling temperature of 26°C. The vehicle controller can also pre-store the startup data corresponding to each type of working status, and the vehicle controller responds to the user's operation and starts the first device according to the preset data. The vehicle controller can also receive the startup data of the first device set by the user, and start the first device according to the data set by the user. For example, the user can click the icon of the first device on the function interface and set the startup data of the first device.
[0123] In other examples, the vehicle controller receives a first signal sent by a remote device, and the vehicle controller starts the first device according to the working status indicated by the first signal.
[0124] The remote device may be an electronic device installed with an application (APP) for remotely controlling the vehicle. The first signal is used to instruct the activation of the first device, and the first signal may include an operating state and an operating temperature, etc.
[0125] It is understandable that the embodiments of the present application do not limit the specific implementation method of starting the first device.
[0126] Optionally, before the vehicle controller obtains the operating status of the first device in the vehicle, it first obtains the status of the first device. If the status of the first device is in the operating state, the subsequent temperature control method is executed; otherwise, the subsequent temperature control method is not executed. That is, the prerequisite for executing the temperature control method in this embodiment of the application is that the first device in the vehicle is started and running.
[0127] The temperature control method provided in the embodiment of the present application can be applied to the application scenario in which the first device is operated. For example, when there are passengers in the vehicle, the passengers start the operation of the first device. Alternatively, the temperature control method provided in the embodiment of the present application can also be applied to the application scenario in which the first device is delayed in powering off in the vehicle (which can be understood as a scenario in which the power is automatically disconnected after a set period of delay after the vehicle stops). For example, a user temporarily gets off the vehicle at a service area and leaves. Before getting off the vehicle, the first device is turned on in the vehicle. The user clicks the delayed power-off function button in the vehicle, and the functional components that have been turned on in the vehicle (such as the first device) are turned off after a predetermined delay. Alternatively, the temperature control method provided in the embodiment of the present application can also be applied to the application scenario in which the first device is remotely started. For example, before traveling, the first device in the vehicle is remotely started by a remote device. The embodiment of the present application does not limit the application scenario of temperature control.
[0128] S402: The vehicle controller obtains the temperature inside the vehicle.
[0129] In the embodiment of the present application, the in-vehicle temperature is the temperature data in the vehicle obtained in real time after the vehicle controller obtains the working status of the first device.
[0130] In some embodiments of the present application, the vehicle controller obtains the temperature inside the vehicle in real time through a temperature sensor installed on the vehicle.
[0131] For example, the temperature data inside the car can be detected in real time by installing temperature sensors at key locations in the car (such as the dashboard, seats, center console, etc.).
[0132] In other embodiments of the present application, the vehicle controller obtains the vehicle interior temperature from various subsystems of the vehicle.
[0133] In some examples, if the second device is turned on, the vehicle controller can interact with the second device to obtain the vehicle interior temperature in real time. For example, in the example of vehicle 300 described above, the vehicle controller interacts with the vehicle air conditioner 346 of vehicle 300 to obtain the vehicle interior temperature.
[0134] It is understandable that the embodiments of the present application do not limit the specific implementation method of the vehicle controller obtaining the temperature inside the vehicle.
[0135] S403: When the temperature inside the vehicle is greater than a first temperature threshold and the working state of the first device is a cooling state, the vehicle controller operates the second device inside the vehicle to lower the temperature inside the vehicle.
[0136] In the embodiment of the present application, the first temperature threshold is a predetermined maximum temperature threshold at which the first device can operate for cooling without reducing cooling efficiency. That is, when the vehicle interior temperature is less than or equal to the first temperature threshold, the first device has high cooling efficiency. When the vehicle interior temperature is greater than the first temperature threshold, the first device has reduced cooling efficiency and cannot provide efficient cooling.
[0137] In some examples, the first temperature threshold is a temperature value obtained experimentally. For example, the cooling efficiency of the first device when operating at different temperatures is tested. If the cooling efficiency of the first device continuously decreases after a certain temperature (e.g., 30 degrees Celsius), the temperature (30 degrees Celsius) is determined as the first temperature threshold.
[0138] In other examples, the first temperature threshold may be determined based on historical data or experience. The embodiments of the present application do not limit the specific method for determining the first temperature threshold and the specific value of the first temperature threshold.
[0139] In the embodiment of the present application, the second device is an onboard air conditioner for regulating the temperature inside the vehicle.
[0140] In this embodiment of the present application, for each operating state of the first device, a temperature threshold that affects the operating efficiency of that operating state is determined, and a corresponding control strategy is set based on whether the vehicle interior temperature exceeds the temperature threshold. In other words, in this embodiment of the present application, the first device and the second device are linked to control the vehicle interior temperature to maintain a temperature suitable for the efficient operation of the first device, thereby ensuring the operating efficiency of the first device.
[0141] Specifically, if the vehicle interior temperature is greater than the first temperature threshold and the first device is in cooling mode, the current vehicle interior temperature is high, affecting the cooling efficiency of the first device. Therefore, the vehicle controller operates the second device in the vehicle to lower the vehicle interior temperature. If the vehicle interior temperature is less than or equal to the first temperature threshold and the first device is in cooling mode, the current vehicle interior temperature does not affect the cooling efficiency of the first device. Therefore, there is no need to operate the second device to adjust the vehicle interior temperature.
[0142] In some embodiments of the present application, the vehicle controller operates a second device in the vehicle to lower the temperature inside the vehicle, including: when the second device is not started, the vehicle controller starts the second device and operates the second device according to the first temperature setting value to lower the temperature inside the vehicle.
[0143] The first temperature setting value may be a pre-set temperature value that does not exceed the first temperature threshold. The first temperature setting value may also be a temperature value that does not exceed the first temperature threshold and that was recently used by the user in historical data stored in the vehicle controller. The first temperature setting value may also be a temperature value set by the user that does not exceed the first temperature threshold.
[0144] For example, taking the first temperature threshold of 30°C as an example, the first temperature setting value can be any temperature value less than or equal to 30°C, such as 28°C. For example, a user turns on the first device while driving and enables cooling. The vehicle controller detects the interior temperature of 31°C through a temperature sensor. The vehicle controller compares the current interior temperature (31°C) with the first temperature threshold (30°C) and determines that the current interior temperature is greater than the first temperature threshold. The vehicle controller activates the second device and operates it according to the pre-set first temperature threshold of 28°C to lower the interior temperature. For another example, the user turns on the second device during the last drive, and the second device blows cold air, and the operating temperature of the second device is 26°C. When the user drives the vehicle again, the first device is turned on and cooling is enabled. The vehicle controller detects the current interior temperature (e.g., 30.5°C) and determines through comparison that the current interior temperature is greater than the first temperature threshold (30.5°C). The vehicle controller activates the second device and operates it according to the temperature value (26°C) when the second device was last operated, to lower the interior temperature.
[0145] In other embodiments of the present application, the vehicle controller operates a second device in the vehicle to lower the temperature inside the vehicle, including: when the second device is started, the vehicle controller operates the second device according to a second temperature setting value to lower the temperature inside the vehicle.
[0146] It is understandable that, in the current situation, although the second device has been started in the vehicle, the temperature in the vehicle still exceeds the first temperature threshold. Therefore, it is necessary to reduce the temperature value when the second device is running to reduce the temperature inside the vehicle.
[0147] The second temperature setting value is a pre-set temperature value that does not exceed the first temperature threshold. The second temperature setting value may also be a temperature value that does not exceed the first temperature threshold and that was recently used by the user in historical data stored in the vehicle controller. The second temperature setting value may also be a temperature value that does not exceed the first temperature threshold and that is set by the user. The second temperature setting value may also be a temperature value that does not exceed the first temperature threshold and that is automatically set by the vehicle controller based on the temperature value currently at the time the second device is operating.
[0148] It will be appreciated that the second temperature setting value may be the same as or different from the first temperature setting value.
[0149] For example, in winter, drinks are refrigerated in the car refrigerator and the car air conditioner is set to 31°C. Although the car air conditioner is running, the temperature inside the car gradually rises to 31°C, which exceeds the first temperature threshold (30°C) in the cooling state of the car refrigerator. Therefore, it is necessary to lower the current temperature value of the car air conditioner setting, such as setting the temperature value of the car air conditioner to 29°C, to lower the temperature inside the car.
[0150] It is understandable that the embodiments of the present application do not limit the specific implementation method of starting and running the second device.
[0151] In an embodiment of the present application, when the vehicle controller determines that the temperature inside the vehicle is greater than the first temperature threshold, it can also prompt the user in a preset manner to adjust the temperature inside the vehicle through the second device.
[0152] For example, when the vehicle controller determines that the temperature inside the vehicle is greater than the first temperature threshold, it can prompt the user through voice broadcast or visual reminder on the display interface such as the instrument panel, etc., that the current temperature inside the vehicle is high and the second device needs to be turned on to lower the temperature inside the vehicle.
[0153] It's understandable that the above example only illustrates the vehicle controller operating the second device to lower the vehicle's interior temperature, but doesn't specify how to shut down the second device. To conserve power and prevent the second device from running for extended periods and consuming excessive power, potentially preventing the vehicle from starting, it's also necessary to configure a shutdown condition for the second device.
[0154] In some embodiments of the present application, after the vehicle controller operates the second device in the vehicle to lower the temperature inside the vehicle, the method further includes: the vehicle controller turns off the second device after a preset time period.
[0155] The preset duration may be a duration preset by the system or a duration set by the user.
[0156] In some examples, the vehicle controller receives a user operation during startup of the second device, determines a preset operation time of the second device, and shuts down the second device after the second device has operated for the preset time.
[0157] In other examples, the vehicle controller automatically shuts down the second device after the second device runs for a preset time period set by the system.
[0158] In other embodiments of the present application, after the vehicle controller operates the second device in the vehicle to lower the temperature inside the vehicle, it also includes: automatically shutting down the second device when the temperature inside the vehicle is less than or equal to a third temperature threshold.
[0159] The third temperature threshold may be a temperature value that is less than or equal to the first temperature threshold.
[0160] It is understandable that after the vehicle controller runs the second device (cooling), the temperature inside the car gradually decreases. When the temperature inside the car is less than or equal to the third temperature threshold, it means that the temperature inside the car does not exceed the first temperature threshold at this time. At this temperature, the first device can efficiently cool. Therefore, the second device can be turned off, and the temperature inside the car will gradually rise from the third temperature threshold. When the temperature inside the car is greater than the first temperature threshold again, the second device for cooling is started again. In actual applications, the third temperature threshold is usually a temperature value (such as 28°C) that is less than the first temperature threshold. In this way, there is a gap between the third temperature threshold and the first temperature threshold. It takes a long time for the temperature inside the car to rise from the third temperature threshold to the first temperature threshold. The heating process is a relatively slow process, which can avoid turning on the second device multiple times in a short period of time (or frequently turning on the second device), extending the use interval of the second device, and reducing power consumption.
[0161] In other embodiments of the present application, after the vehicle controller operates the second device in the vehicle to lower the temperature inside the vehicle, it also includes: when the temperature inside the vehicle is less than or equal to the first temperature threshold, obtaining the temperature outside the vehicle; if the temperature outside the vehicle is less than or equal to the first temperature threshold, setting the state of the second device to the external circulation state.
[0162] The external circulation state is an operating mode of the second device, in which the second device draws in air from outside the vehicle and circulates it into the vehicle, that is, the fresh air outside the vehicle flows into the vehicle to ventilate the vehicle.
[0163] Specifically, after the vehicle controller activates the second device to cool the interior of the vehicle, the interior temperature gradually decreases. When the interior temperature is less than or equal to a first temperature threshold, the exterior temperature is acquired. If the exterior temperature is less than or equal to the first temperature threshold, indicating that the exterior and interior temperatures are similar and both are below the first temperature threshold, the cooling mode of the second device is disabled, and the second device is set to external circulation, allowing air to circulate with the exterior, thereby conserving power in the second device.
[0164] It's understandable that the vehicle controller operating the second device inside the vehicle to lower the interior temperature is an internal circulation process. The vehicle controller controls the second device to cool the interior, but at this point, the airflow inside and outside the vehicle is disconnected. When both the outside temperature and the inside temperature are less than or equal to the first temperature threshold, indicating a close difference in temperature, the air conditioning cooling mode can be turned off and the external circulation activated. This maintains the interior temperature while allowing fresh air to flow in, improving user comfort and saving power.
[0165] In some other embodiments of the present application, when the vehicle power level is less than a preset power threshold, the vehicle controller turns off the first device and / or the second device.
[0166] The preset power threshold may be a preset minimum threshold value of power required to ensure normal driving of the vehicle, for example, the preset power threshold is 10%.
[0167] It is understandable that the embodiments of the present application do not limit the specific implementation method of the vehicle controller turning off the second device.
[0168] It is understandable that the operation of the first device and the second device requires power from the vehicle battery. When the vehicle battery is less than the preset power threshold, the vehicle should first be kept running normally and other power-consuming components, such as the first device and / or the second device, should be turned off.
[0169] Exemplarily, as shown in FIG5 , a temperature control flow chart is shown in the scenario where the user has turned on the first device and the vehicle is powered off with a delayed shutdown.
[0170] S501: The vehicle controller receives an operation by a user to trigger delayed power-off of the vehicle, obtains the working status of a first device in the vehicle in response to the operation, and maintains the working status for a preset time.
[0171] In the embodiment of the present application, the vehicle controller receives an operation by a user to trigger a delayed power-off of the vehicle and obtains the working state of the first device in the vehicle. The working state includes a cooling state or a heating state.
[0172] S502: The vehicle controller obtains the temperature inside the vehicle.
[0173] In the embodiment of the present application, the specific implementation method of step S502 is described in the above S402 and will not be repeated here.
[0174] S503: The vehicle controller determines whether the temperature inside the vehicle meets the temperature threshold corresponding to the working state. If so, execute S504; otherwise, execute S505.
[0175] In the embodiment of the present application, when the working state of the first device is the cooling state, whether the temperature inside the vehicle meets the temperature threshold corresponding to the working state is specifically: whether the temperature inside the vehicle is greater than the first temperature threshold corresponding to the cooling state.
[0176] Specifically, the vehicle controller determines that the first device corresponds to the first temperature threshold in the cooling state, and determines by comparison whether the current temperature inside the vehicle is greater than the first temperature threshold. If so, execute S504; otherwise, execute S505.
[0177] In the embodiment of the present application, when the working state of the first device is the heating state, whether the temperature inside the vehicle meets the temperature threshold corresponding to the working state is specifically: whether the temperature inside the vehicle is lower than the second temperature threshold corresponding to the heating state.
[0178] Specifically, the vehicle controller determines that the first device corresponds to the second temperature threshold in the heating state, and determines by comparison whether the current temperature inside the vehicle is less than the second temperature threshold. If so, execute S504; otherwise, execute S505.
[0179] S504: The vehicle controller operates the second device in the vehicle to adjust the temperature inside the vehicle.
[0180] In an embodiment of the present application, when the working state of the first device is a cooling state and the temperature inside the vehicle is greater than a first temperature threshold corresponding to the cooling state, the vehicle controller operates the second device in the vehicle to lower the temperature inside the vehicle.
[0181] In an embodiment of the present application, when the working state of the first device is the heating state and the temperature inside the vehicle is lower than the second temperature threshold corresponding to the heating state, the vehicle controller operates the second device in the vehicle to increase the temperature inside the vehicle.
[0182] In the embodiment of the present application, the specific implementation method of step S504 is described in S403 or S404 above and will not be repeated here.
[0183] S505: The vehicle controller does not perform any operation.
[0184] It is understandable that the above examples are described with the first device operating in the cooling state as an example, and the temperature control method is described below with the first device operating in the heating state as an example.
[0185] S404: When the temperature inside the vehicle is lower than a second temperature threshold and the working state of the first device is a heating state, the vehicle controller operates the second device inside the vehicle to increase the temperature inside the vehicle.
[0186] In the embodiment of the present application, the second temperature threshold is a predetermined minimum temperature threshold at which the first device can operate for heating without reducing heating efficiency. That is, when the vehicle interior temperature is greater than or equal to the second temperature threshold, the first device has high heating efficiency. When the vehicle interior temperature is less than the second temperature threshold, the first device has reduced heating efficiency and cannot provide efficient heating.
[0187] In some examples, the second temperature threshold is a temperature value obtained through experiments. Alternatively, the second temperature threshold can also be determined based on historical data or experience. For example, the second temperature threshold is 10°C.
[0188] In this embodiment of the present application, for each operating state of the first device, a temperature threshold that affects the operating efficiency of that operating state is determined, and a corresponding control strategy is set based on whether the vehicle interior temperature exceeds the temperature threshold. In other words, in this embodiment of the present application, the first device and the second device are linked to control the vehicle interior temperature to maintain a temperature suitable for the efficient operation of the first device, thereby ensuring the operating efficiency of the first device.
[0189] Specifically, if the vehicle interior temperature is less than the second temperature threshold and the first device is operating in the heating state, the current vehicle interior temperature is low, affecting the heating efficiency of the first device. Therefore, the vehicle controller operates the second device in the vehicle to increase the vehicle interior temperature. If the vehicle interior temperature is greater than or equal to the second temperature threshold and the first device is operating in the heating state, the current vehicle interior temperature does not affect the heating efficiency of the first device, and therefore, there is no need to operate the second device to adjust the vehicle interior temperature.
[0190] In some embodiments of the present application, the vehicle controller activates a second device in the vehicle to increase the temperature inside the vehicle, including: when the second device is not started, the vehicle controller starts the second device and operates the second device according to a third temperature setting value to increase the temperature inside the vehicle.
[0191] The third temperature setting value may be a pre-set temperature value greater than or equal to the second temperature threshold. The third temperature setting value may also be a temperature value greater than or equal to the second temperature threshold that was recently used by the user in historical data stored in the vehicle controller. The third temperature setting value may also be a temperature value greater than or equal to the second temperature threshold that is set by the user.
[0192] For example, taking the second temperature threshold of 10°C as an example, the third temperature setting value may be any temperature value greater than or equal to 10°C, such as 18°C.
[0193] In other embodiments of the present application, the vehicle controller operates a second device in the vehicle to increase the temperature inside the vehicle, including: when the second device is started, the vehicle controller operates the second device according to a fourth temperature setting value to increase the temperature inside the vehicle.
[0194] It is understandable that, in the current situation, although the second device has been started in the vehicle, the temperature in the vehicle is still lower than the second temperature threshold. Therefore, it is necessary to increase the temperature value when the second device is running to increase the temperature inside the vehicle.
[0195] The fourth temperature setting value is a pre-set temperature value greater than or equal to the second temperature threshold. The fourth temperature setting value may also be a temperature value greater than or equal to the second temperature threshold that was recently used by the user and is stored in historical data in the vehicle controller. The fourth temperature setting value may also be a temperature value greater than or equal to the second temperature threshold that is set by the user. The fourth temperature setting value may also be a temperature value greater than or equal to the second temperature threshold that is automatically set by the vehicle controller based on the temperature value currently at the time the second device is operating.
[0196] It will be appreciated that the fourth temperature setting value may be the same as or different from the third temperature setting value.
[0197] It is understandable that the embodiments of the present application do not limit the specific implementation method of starting and running the second device.
[0198] In an embodiment of the present application, when the vehicle controller determines that the temperature inside the vehicle is lower than the second temperature threshold, it can also prompt the user in a preset manner to adjust the temperature inside the vehicle through the second device.
[0199] It is understandable that the specific implementation method of the vehicle controller reminding the user in the embodiment of the present application can be found in S403 above or the prior art, and will not be repeated here.
[0200] In some embodiments of the present application, after the vehicle controller operates the second device in the vehicle to increase the temperature inside the vehicle, the method further includes: the vehicle controller turns off the second device after a preset time period.
[0201] It is understandable that the specific implementation method of the vehicle controller turning off the second device after the preset time period is described in S403 above and will not be repeated here.
[0202] In another embodiment of the present application, after the vehicle controller operates the second device in the vehicle to increase the temperature inside the vehicle, it also includes: automatically shutting down the second device when the temperature inside the vehicle is greater than or equal to a fourth temperature threshold.
[0203] The fourth temperature threshold may be a temperature value greater than or equal to the second temperature threshold.
[0204] It is understandable that after the vehicle controller runs the second device (heating), the temperature inside the car gradually rises. When the temperature inside the car is greater than or equal to the fourth temperature threshold, it means that the temperature inside the car is greater than or equal to the second temperature threshold. At this temperature, the first device can efficiently heat. Therefore, the second device can be turned off, and the temperature inside the car will start from the lower temperature threshold and gradually cool down. When the temperature inside the car is lower than the second temperature threshold again, the second device is started again for heating. In actual applications, the fourth temperature threshold is usually a temperature value greater than the second temperature threshold. This can avoid turning on the second device multiple times in a short period of time, extend the use interval of the second device, and reduce power consumption.
[0205] In other embodiments of the present application, after the vehicle controller operates the second device in the vehicle to lower the temperature inside the vehicle, it also includes: when the temperature inside the vehicle is greater than or equal to the second temperature threshold, obtaining the temperature outside the vehicle; if the temperature outside the vehicle is greater than or equal to the second temperature threshold, setting the second device to the external circulation state.
[0206] Specifically, after the vehicle controller activates the second device to heat the vehicle interior, the interior temperature gradually rises. When the interior temperature is greater than or equal to a second temperature threshold, the exterior temperature is acquired. If the exterior temperature is greater than or equal to the second temperature threshold, this indicates that the exterior and interior temperatures are similar and both exceed the second temperature threshold. Therefore, the heating mode of the second device can be turned off, and the second device can be set to external circulation, communicating with the outside air. This maintains the interior temperature while conserving power to the second device.
[0207] In some other embodiments of the present application, when the vehicle power level is less than a preset power threshold, the vehicle controller turns off the first device and / or the second device.
[0208] It is understandable that the embodiment of the present application does not limit the specific implementation method of the vehicle controller turning off the second device. For details, please refer to the above S403 and will not be repeated here.
[0209] Exemplarily, as shown in FIG6 , a temperature control flow chart of an application scenario in which a user remotely operates to turn on the first device and a vehicle remotely starts the first device is shown.
[0210] S601: The vehicle controller obtains the working status of the first device in the vehicle in response to the user starting the first device through the remote device.
[0211] In an embodiment of the present application, the vehicle controller receives an operation of starting a first device by a user through a remote device, and in response to the operation, obtains the working state of the first device in the vehicle, wherein the working state includes a cooling state or a heating state.
[0212] S602: The vehicle controller obtains the temperature inside the vehicle.
[0213] In the embodiment of the present application, the specific implementation method of step S602 is described in S402 above and will not be repeated here.
[0214] S603: The vehicle controller determines whether the temperature inside the vehicle meets the temperature threshold corresponding to the working state. If so, execute S604; otherwise, execute S605.
[0215] In the embodiment of the present application, the specific implementation method of step S603 is as described above in S503 and will not be repeated here.
[0216] S604: The vehicle controller operates the second device in the vehicle to adjust the temperature inside the vehicle.
[0217] In the embodiment of the present application, the specific implementation method of step S604 is described in S504 above and will not be repeated here.
[0218] S605: The vehicle controller does not perform any operation.
[0219] Through the above process, the vehicle controller in the embodiment of the present application can operate the working state of the first device and the temperature inside the vehicle, and the working state includes the cooling state and the heating state. When the temperature inside the vehicle is greater than the first temperature threshold and the working state of the first device is the cooling state, the second device in the vehicle is operated to reduce the temperature inside the vehicle; or, when the temperature inside the vehicle is less than the second temperature threshold and the working state of the first device is the heating state, the second device in the vehicle is operated to increase the temperature inside the vehicle. The solution of the embodiment of the present application, according to the working state of the first device, when the temperature inside the vehicle affects the efficiency of the first device in this working state, the temperature inside the vehicle is regulated by the second device, so that the first device works efficiently. The method provided in the embodiment of the present application can realize the efficient operation of the car refrigerator at a low cost, ensure the normal use of the car refrigerator under different ambient temperatures, and increase the use scenarios of the car refrigerator.
