Background Art

With the rapid development of the transportation industry, more and more vehicles are equipped with car refrigerators to meet users' needs for refrigerated and fresh food, so as to improve the comfort and safety of users' outdoor travel. At present, there are two main types of car refrigerators. One is the compressor car refrigerator, which has high refrigeration efficiency, but slow response speed, heavy weight and high cost. The other is the semiconductor car refrigerator, which has fast response speed, light weight and low cost, but low refrigeration efficiency.

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.

Summary of the invention

The embodiments of the present application provide a temperature control method, device and vehicle, which can realize efficient operation of a vehicle refrigerator at low cost.

In order to achieve the above objectives, the present application provides the following technical solutions:

In a first aspect, an embodiment of the present application provides a temperature control method, which includes: obtaining a working state of a first device in a vehicle, the working state 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 state 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 state of the first device is a heating state, operating the second device in the vehicle to increase the temperature in the vehicle.

In this way, according to the working state of the first device, when the temperature inside the vehicle affects the efficiency of the first device in the working state, the temperature inside the vehicle is regulated by the second device so that the first device works efficiently. By linking the first device and the second device to control the temperature inside the vehicle, the car refrigerator can work efficiently at a low cost, ensuring the normal use of the car refrigerator under different ambient temperatures, and increasing the use scenarios of the car refrigerator.

According to the first aspect, the first device is a vehicle refrigerator, and the second device is a vehicle air conditioner.

In some examples, the first device is a semiconductor vehicle refrigerator that provides refrigeration or heat preservation functions in the vehicle.

According to the first aspect, or any implementation of the first aspect above, the working status of the first device is acquired through various sensors installed on the vehicle.

According to the first aspect, or any implementation of the first aspect above, the working status of the first device is obtained from various subsystems of the vehicle.

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 the start-up of the first device; 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.

In some examples, in response to a user's operation of starting a first device in a vehicle, an operating status or preset data or data set by the user when the first device was last run is obtained, and the first device is started according to the operating status or preset data or data set by the user when the first device was last run.

In some examples, the temperature inside the vehicle is obtained in real time through a temperature sensor installed on the vehicle.

In other examples, the vehicle interior temperature is obtained from various subsystems of the vehicle.

In this way, the vehicle interior temperature is acquired in real time according to the real-time working status of the first device, so as to subsequently accurately determine whether the vehicle interior temperature affects the working efficiency of the first device.

In some examples, the first temperature threshold is a predetermined maximum temperature threshold value at which the first device can perform cooling operation without reducing cooling efficiency.

In some other examples, the second temperature threshold is a predetermined minimum temperature threshold at which the first device performs heating operation without reducing heating efficiency.

In this way, corresponding temperature thresholds are pre-set for different working states of the first device 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, allowing the first device to continue working with higher working efficiency and improve the refrigeration or insulation effect.

According to the first aspect, or any implementation of the first aspect above, running a second device in a 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 a first temperature setting value to lower the temperature inside the vehicle.

According to the first aspect, or any implementation of the first aspect above, operating a second device in a vehicle to lower the temperature inside the vehicle includes: when the second device is started, operating the second device according to a second temperature setting value to lower the temperature inside the vehicle.

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.

In this way, when the working state of the first device is the cooling state and the temperature inside the vehicle is greater than the first temperature threshold, the temperature inside the vehicle is lowered by running the second device, so that the temperature inside the vehicle is lowered to a temperature at which the working efficiency of the first device is not affected in the cooling state. Even if the first device is in a high temperature environment, the ambient temperature can be lowered by the second device to ensure the high efficiency operation of the first device and meet the diverse needs of users.

According to the first aspect, or any implementation of the first aspect above, operating a second device in a 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 a third temperature setting value to increase the temperature inside the vehicle.

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.

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.

In this way, 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, the temperature inside the vehicle is increased by running the second device, so that the temperature inside the vehicle is increased to a temperature when the first device is in the heating state and does not affect the working efficiency. Even if the first device is in a low temperature environment, the ambient temperature can be increased by the second device to ensure the high efficiency operation of the first device and meet the diverse needs of users.

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 a user in a preset manner to adjust the temperature inside the vehicle through a second device.

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 settings of the second device, which is conducive to providing a comfortable riding environment and increasing riding comfort and safety.

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.

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.

In some examples, the third temperature threshold is less than or equal to the first temperature threshold.

In this way, when the second device is running for cooling, the temperature inside the car gradually decreases. When the temperature inside the car is less than or equal to the third temperature threshold, the temperature inside the car can meet the needs of efficient cooling of the first device, and the second device is automatically turned off to avoid the second device from consuming too much power for a long time, saving power and resources. Moreover, when the third temperature threshold is less than the first temperature threshold, there is a gap between the third temperature threshold and the first temperature threshold, which can avoid frequent activation of the second device, extend the use interval of the second device, reduce power consumption, and save more power.

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.

In some examples, the fourth temperature threshold is greater than or equal to the second temperature threshold.

In this way, when the second device is in heating operation, the temperature inside the vehicle is gradually increased. When the temperature inside the vehicle is greater than or equal to the fourth temperature threshold When the temperature in the car meets the requirement of efficient heating of the first device, the second device is automatically turned off to avoid the second device from running for a long time and consuming too much power, thus saving power and resources. Moreover, 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 avoid frequent activation of the second device, extend the use interval of the second device, reduce power consumption, and save more power.

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.

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 an external circulation state.

In some examples, when the temperature inside the vehicle drops to a first temperature threshold or is lower than the first temperature threshold, if the temperature outside the vehicle does not exceed the first temperature threshold, the cooling function of the second device is turned off and the external circulation state is turned on. Alternatively, when the temperature inside the vehicle rises to a second temperature threshold or is higher than the second temperature threshold, if the temperature outside the vehicle is not lower than the second temperature threshold, the heating function of the second device is turned off and the external circulation state is turned on. In this way, the temperature inside the vehicle can be maintained to ensure the efficient operation of the first device, and fresh air can be introduced into the vehicle, which is conducive to improving user comfort and saving electricity.

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.

In this way, it is avoided that the first device and/or the second device consumes too much electricity due to long-term operation, causing the vehicle to be unable to drive normally.

DETAILED DESCRIPTION

In the description of the embodiments of the present application, unless otherwise specified, “/” means or. For example, A/B can mean A or B. The “and/or” in this article is merely a way to describe the association relationship of associated objects, indicating that three relationships may exist. For example, A and/or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

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 scheme described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more appropriate than other embodiments or design schemes. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

In some examples, a car refrigerator can use a compressor to achieve refrigeration 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. The compressor car refrigerator has a high refrigeration efficiency and is not affected by the environment, but it is heavy and costly. For example, after the compressor car refrigerator works continuously for two hours at any temperature in the ambient temperature range of 30℃-35℃, the internal temperature of the compressor car refrigerator drops by an average of 8.5℃.

In other examples, car refrigerators can also use semiconductors to achieve refrigeration and heat preservation functions. Specifically, based on the Peltier effect, temperature regulation is achieved by current in semiconductor materials, and cooling or heating is achieved by changing the direction of the current. The refrigeration efficiency of semiconductor car refrigerators is affected by the surrounding environment. The higher the ambient temperature, the worse the refrigeration efficiency, but it is light in weight and low in cost. For example, after the 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 the 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.

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 a 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 the first temperature threshold and the working state of the first device is a cooling state, runs the second device in the car to reduce the temperature in the car; or, when the temperature in the car is less than the 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 scheme 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 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.

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 of the embodiments.

The temperature control method in the embodiment of the present application can be applied to various devices using a vehicle refrigerator (also described as a first device) and a vehicle air conditioner (also described as a second device). The various devices may include various transportation tools such as new energy vehicles, electric vehicles, buses, and cars.

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 is a vehicle refrigerator that provides cooling or heat preservation functions in the vehicle. The first device 11 is a semiconductor vehicle refrigerator. The working state of the first device 11 during operation includes a cooling state and a heating state. For example, when the working state of the first device 11 is a cooling state, the first device 11 is used to refrigerate food.

The acquisition module 12 can be used to acquire the working state 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 state of the first device and the temperature in the vehicle to the temperature control device 13 .

The acquisition module 12 includes a vehicle sensor, which is usually arranged inside the vehicle. The vehicle sensor can be used to detect the working state of the first device of the vehicle and the temperature inside the vehicle. The vehicle sensor can be any one of a temperature sensor, a photoelectric speed sensor, a magnetoelectric speed sensor, and a Hall-type speed sensor, which is not limited thereto.

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 a wireless communication network.

It should be understood that the above description of the acquisition module 12 is only an exemplary description, and the embodiment of the present application does not specifically limit the specific form and implementation method of the acquisition module 12.

Alternatively, when the temperature control device 13 determines that the temperature in the vehicle is less than the second temperature threshold and the operation state of the first device is in the heating state, the temperature control device 13 interacts with the second device 14 to control the operation of the second device 14 to increase the temperature in the vehicle.

In other examples, the temperature control device 13 obtains the working state of the first device from the first device 11, and obtains the in-vehicle temperature from the obtaining module 12.

The intelligent driving computing platform interacts with various components in the vehicle, obtains real-time data of each component, and controls the operation of each component.

The second device 14 is a vehicle 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.

It can be understood 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 practical applications, the acquisition module 12 and the temperature control device 13 can be deployed on the same component, such as the temperature control device 13 is an intelligent driving computing platform, and 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.

Alternatively, one or more of the above-mentioned components may be installed or associated separately from the vehicle 300. For example, the memory 362 may exist partially or completely separately from the vehicle 300. The above-mentioned components may be communicatively coupled together in a wired and/or wireless manner.

Optionally, the above components are only an example. In practical applications, the components in the above modules may be added or deleted according to actual needs. FIG. 3 should not be understood as a limitation on the embodiments of the present application.

The vehicle 300 may be a new energy vehicle, an electric vehicle, a car, a car, a truck, a motorcycle, a bus, a ship, an airplane, a helicopter, a lawn mower, an entertainment vehicle, an amusement park vehicle, construction equipment, a tram, a golf cart, and a train, etc., and the embodiment of the present application does not make any special restrictions. The power of the vehicle may be provided by gasoline, diesel, electricity, solar energy, hydrogen energy, etc.

In other embodiments of the present application, the vehicle may further include a hardware structure and/or a software module to implement the above functions in the form of a hardware structure, a software module, or a hardware structure plus a software module. Whether one of the above functions is implemented in the form of a hardware structure, a software module, or a hardware structure plus a software module depends on the specific application and design constraints of the technical solution.

The method provided in the embodiments of the present application is described below with reference to the accompanying drawings.

In order to improve the working efficiency of the vehicle refrigerator at a low cost, the present application proposes a temperature control method, which can be applied to various devices using a vehicle refrigerator (hereinafter described as a first device) and a vehicle air conditioner (hereinafter described as a second device), such as the vehicle 300 shown in FIG3. The execution subject of the method can be a vehicle or other devices outside the vehicle, or a processor on the vehicle or other devices outside the vehicle, such as the processor 21 and the processor 361 mentioned in the above content.

The embodiment of the present application is introduced by taking a new energy vehicle as an example. Referring to FIG. 4 , FIG. 4 shows a schematic flow chart of a temperature control method provided in the embodiment of the present application. The temperature control method includes the following S401-S404:

S401. The vehicle controller obtains the working state of the first device in the vehicle, where the working state includes a cooling state and a heating state.

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 actions of various components in the vehicle (such as controlling the operation of the second device) are controlled, thereby adjusting the temperature inside the vehicle.

In the embodiment of the present application, the first device is a vehicle refrigerator that provides cooling or heat preservation functions in the vehicle. The first device is a semiconductor vehicle refrigerator.

In the embodiment of the present application, the state of the first device includes a working state and a non-working state. The working state is a state in which the first device is enabled, the first device is running, and provides a refrigeration or heating and heat preservation function. The non-working state is a state in which the first device is not enabled, which can also be understood as the first device is not powered on or the first device is not running.

The working state includes a cooling state and a heating state. When the working state of the first device is a cooling state, the first device provides a refrigeration function. When the working state of the first device is a heating state, the first device provides a heat preservation function.

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.

Optionally, the working status of the first device in the vehicle may be indicated by a flag.

In some examples, a flag is set for the working state of the first device, and the working state of the first device in the vehicle is indicated by the flag value. For example, if the working state of the first device is 1, it indicates that the first device is in a cooling state. If the working state is 2, it means that the first device is in the heating state. If the state of the first device is 0, it means that the first device is in the Wei Gongzi state. The specific representation method of the working state of the first device is not specifically limited in the embodiment of the present application.

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.

In some other embodiments of the present application, the vehicle controller obtains the working state of the first device from various subsystems of the vehicle. For example, in the example of the vehicle 300 described above, the vehicle controller obtains the working state of the first device from the refrigerator 345 of the vehicle 300 .

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.

In a possible implementation manner, the vehicle controller starts the first device in response to a user operation.

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 data set by the user 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 data set by the user when the first device was last run.

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 running was a 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, the first device is started 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.

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 state indicated by the first signal.

The remote device may be an electronic device installed with an application (APP) for remotely controlling the vehicle. The first signal is used to indicate starting the first device, and the first signal may include a working state and a working temperature, etc.

It is understandable that the embodiments of the present application do not limit the specific implementation method of starting the first device.

Optionally, before the vehicle controller obtains the working state of the first device in the vehicle, the state of the first device is obtained first, and if the state of the first device is in the working 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 the embodiment of the present application is that the first device in the vehicle has been started and operated.

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 in the delayed power-off scenario (which can be understood as a scenario in which the power is automatically disconnected after a set delay after a period of time after the vehicle stops). For example, the user temporarily gets off the vehicle in 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.

S402: The vehicle controller obtains the temperature inside the vehicle.

In the embodiment of the present application, the in-vehicle temperature is the temperature data in the vehicle acquired in real time after the vehicle controller acquires the working status of the first device.

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.

For example, 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.).

In other embodiments of the present application, the vehicle controller obtains the in-vehicle temperature from various subsystems of the vehicle.

In some examples, if the second device is turned on, the vehicle controller can obtain the temperature inside the vehicle in real time by interacting with the second device. For example, in the example of vehicle 300 described above, the vehicle controller interacts with the vehicle air conditioner 346 of the vehicle 300 to obtain the temperature inside the vehicle.

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.

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 a second device inside the vehicle to lower the temperature inside the vehicle.

In the embodiment of the present application, the first temperature threshold is a predetermined maximum temperature threshold at which the first device operates for cooling without reducing the cooling efficiency. That is, when the temperature inside the vehicle is less than or equal to the first temperature threshold, the cooling efficiency of the first device is high, and when the temperature inside the vehicle is greater than the first temperature threshold, the cooling efficiency of the first device is reduced and cannot be cooled efficiently.

In some examples, the first temperature threshold is a temperature value obtained by experiment. For example, the cooling efficiency of the first device when operating at different temperatures is tested, and if the cooling efficiency of the first device continues to decrease after a certain temperature (such as 30 degrees Celsius), the temperature (30 degrees Celsius) is determined as the first temperature threshold.

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.

In the embodiment of the present application, the second device is an onboard air conditioner for adjusting the temperature inside the vehicle.

In the embodiment of the present application, for each working state of the first device, a temperature threshold that affects the working efficiency in the working state is determined, and a corresponding control strategy is set according to whether the temperature inside the vehicle exceeds the temperature threshold. That is, in the embodiment of the present application, the first device and the second device are linked to control the temperature inside the vehicle to maintain a temperature suitable for the efficient operation of the first device, thereby ensuring the working efficiency of the first device.

Specifically, when the temperature inside the vehicle is greater than the first temperature threshold and the working state of the first device is in the cooling state, it indicates that the current temperature inside the vehicle is high, which affects the cooling efficiency of the first device. Therefore, the vehicle controller operates the second device inside the vehicle to reduce the temperature inside the vehicle. When the temperature inside the vehicle is less than or equal to the first temperature threshold and the working state of the first device is in the cooling state, it indicates that the current temperature inside the vehicle does not affect the cooling efficiency of the first device, and therefore, there is no need to operate the second device to adjust the temperature inside the vehicle.

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 a first temperature setting value to lower the temperature inside the vehicle.

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 is most recently used by the user in the historical data stored in the vehicle controller. The first temperature setting value may also be a temperature value that does not exceed the first temperature threshold and is set by the user.

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, the user turns on the first device during driving and enables the cooling state. The vehicle controller obtains the temperature in the car as 31°C through the temperature sensor. The vehicle controller determines that the current temperature in the car is greater than the first temperature threshold by comparing the current temperature in the car (31°C) with the first temperature threshold (30°C). The vehicle control starts the second device and runs the second device according to the pre-set first temperature threshold of 28°C to reduce the temperature in the car. For another example, the user turned on the second device during the last driving, the second device blew cold air, and the temperature of the second device during operation was 26°C. When the user drives the vehicle again, the first device is turned on and the cooling state is enabled. The vehicle controller obtains the current temperature in the car (such as 30.5°C), and determines by comparison that the current temperature in the car is greater than the first temperature threshold (30.5°C). The vehicle controller starts the second device and runs the second device according to the temperature value (26°C) when the second device was last operated to reduce the temperature in the car.

In some 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.

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, and therefore, it is necessary to reduce the temperature value when the second device is running to reduce the temperature inside the vehicle.

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 is most recently used by the user and does not exceed the first temperature threshold in the historical data stored in the vehicle controller. The second temperature setting value may also be a temperature value set by the user 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 that is automatically set by the vehicle controller according to the temperature value when the second device is currently running.

It will be appreciated that the second temperature setting value may be the same as or different from the first temperature setting value.

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) under 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.

It is understandable that the embodiments of the present application do not limit the specific implementation method of starting and running the second device.

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.

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 a display interface such as the dashboard 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.

It is understandable that the above example only illustrates that the vehicle controller runs the second device to lower the temperature inside the vehicle, but does not specify how to shut down the second device. In order to save power and prevent the second device from running for a long time and consuming too much power, causing the vehicle to fail to start, it is also necessary to set the shutdown condition of the second device.

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, it also includes: the vehicle controller turns off the second device after a preset period of time.

The preset duration may be a duration preset by the system or a duration set by the user.

In some examples, the vehicle controller receives a user operation during the startup of the second device, determines a preset operation time of the second device, and turns off the second device after the second device has been running for the preset time.

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.

In some 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.

The third temperature threshold may be a temperature value that is less than or equal to the first temperature threshold.

It is understandable that after the vehicle controller runs the second device (refrigeration), 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 refrigeration is started again. In actual applications, the third temperature threshold is usually a temperature value (such as 28°C) 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), extend the use interval of the second device, and reduce power consumption.

In other embodiments of the present application, after the vehicle controller runs 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.

The external circulation state is a working mode of the second device, in which the second device inhales air from the air outside the vehicle and circulates it into the vehicle, that is, fresh air outside the vehicle flows into the vehicle to ventilate the vehicle.

Specifically, after the vehicle controller runs the second device to cool down the temperature inside the vehicle, the temperature inside the vehicle gradually decreases. When the temperature inside the vehicle is less than or equal to the first temperature threshold, the temperature outside the vehicle is obtained. If the temperature outside the vehicle is less than or equal to the first temperature threshold, it indicates that the temperature outside the vehicle is not much different from the temperature inside the vehicle, and both are lower than the first temperature threshold. Therefore, the cooling mode of the second device is turned off, and the second device is set to an external circulation state to communicate with the air outside the vehicle, saving power of the second device.

It is understandable that the vehicle controller operates the second device in the vehicle to reduce the temperature in the vehicle, which is an internal circulation process. The vehicle controller controls the second device to cool down the temperature in the vehicle. At this time, the airflow inside and outside the vehicle is not intercommunication. When the outside temperature/inside temperature are both less than or equal to the first temperature threshold, it indicates that the temperature difference between inside and outside the vehicle is not large. You can choose to turn off the air conditioning cooling mode and turn on the external circulation to maintain the temperature in the vehicle, and inhale fresh air, which improves user comfort and saves power.

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.

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%.

It can be understood that the embodiment of the present application does not limit the specific implementation method of the vehicle controller turning off the second device.

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 a 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.

Exemplarily, as shown in FIG5 , a temperature control flow chart is shown for a scenario in which the user has turned on the first device and the vehicle is powered off with a delay.

S501: The vehicle controller receives an operation by a user to trigger delayed power-off of the vehicle, and obtains a working state of a first device in the vehicle in response to the operation. working state and maintain the working state within the preset time.

In the embodiment of the present application, the vehicle controller receives an operation of a user triggering 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.

S502: The vehicle controller obtains the temperature inside the vehicle.

In the embodiment of the present application, the specific implementation method of step S502 is as described in S402 above and will not be repeated here.

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.

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.

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.

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 less than the second temperature threshold corresponding to the heating state.

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.

S504: The vehicle controller operates the second device in the vehicle to adjust the temperature in the vehicle.

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.

In an embodiment of the present application, when the working state of the first device is a heating state and the temperature inside the vehicle is lower than a second temperature threshold corresponding to the heating state, the vehicle controller operates the second device inside the vehicle to increase the temperature inside the vehicle.

In the embodiment of the present application, the specific implementation method of step S504 is as described in S403 or S404 above, which will not be repeated here.

S505: The vehicle controller does not perform any operation.

It is understandable that the above example is described by taking the working state of the first device as the cooling state as an example, and the temperature control method is described below by taking the working state of the first device as the heating state as an example. After S402, S404 is also included.

S404: When the temperature inside the vehicle is lower than the 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.

In the embodiment of the present application, the second temperature threshold is a predetermined minimum temperature threshold at which the first device operates for heating without reducing the heating efficiency. That is, when the temperature inside the vehicle is greater than or equal to the second temperature threshold, the heating efficiency of the first device is high, and when the temperature inside the vehicle is less than the second temperature threshold, the heating efficiency of the first device is reduced and cannot be efficiently heated.

In some examples, the second temperature threshold is a temperature value obtained from 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.

In the embodiment of the present application, for each working state of the first device, a temperature threshold that affects the working efficiency in the working state is determined, and a corresponding control strategy is set according to whether the temperature inside the vehicle exceeds the temperature threshold. That is, in the embodiment of the present application, the first device and the second device are linked to control the temperature inside the vehicle to maintain a temperature suitable for the efficient operation of the first device, thereby ensuring the working efficiency of the first device.

Specifically, 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, it indicates that the current temperature inside the vehicle is low, which affects the heating efficiency of the first device. Therefore, the vehicle controller operates the second device inside the vehicle to increase the temperature inside the vehicle. When the temperature inside the vehicle is greater than or equal to the second temperature threshold and the working state of the first device is the heating state, it indicates that the current temperature inside the vehicle does not affect the heating efficiency of the first device, and therefore, there is no need to operate the second device to adjust the temperature inside the vehicle.

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.

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 the 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.

Exemplarily, 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.

In some 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.

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.

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 is most recently used by the user in the historical data stored in the vehicle controller. The fourth temperature setting value may also be a temperature value greater than or equal to the second temperature threshold 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 according to the temperature value when the second device is currently running.

It will be appreciated that the fourth temperature setting value may be the same as or different from the third temperature setting value.

It is understandable that the embodiments of the present application do not limit the specific implementation method of starting and running the second device.

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.

It can be understood 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, which will not be repeated here.

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, it also includes: the vehicle controller turns off the second device after a preset period of time.

It can be understood that the specific implementation method of the vehicle controller turning off the second device after the preset time period is described in S403 above, which will not be repeated here.

In another embodiment of the present application, after the vehicle controller runs 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.

The fourth temperature threshold may be a temperature value greater than or equal to the second temperature threshold.

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 low 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.

In other embodiments of the present application, after the vehicle controller runs 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 an external circulation state.

Specifically, after the vehicle controller runs the second device to heat the vehicle and increase the temperature inside the vehicle, the temperature inside the vehicle gradually rises. When the temperature inside the vehicle is greater than or equal to the second temperature threshold, the temperature outside the vehicle is obtained. If the temperature outside the vehicle is greater than or equal to the second temperature threshold, it indicates that the temperature outside the vehicle is not much different from the temperature inside the vehicle, 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 an external circulation state to communicate with the air outside the vehicle, which can both maintain the temperature inside the vehicle and save the power of the second device.

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.

It can be understood that the embodiment of the present application does not limit the specific implementation method of the vehicle controller turning off the second device. Please refer to the above S403 for details, which will not be repeated here.

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.

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.

In the embodiment of the present application, the vehicle controller receives an operation of starting the first device by a user through a remote device, and obtains the working state of the first device in the vehicle in response to the operation. The working state includes a cooling state or a heating state.

S602: The vehicle controller obtains the temperature inside the vehicle.

In the embodiment of the present application, the specific implementation method of step S602 is as described in S402 above and will not be repeated here.

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.

In the embodiment of the present application, the specific implementation method of step S603 refers to the above description of S503 and will not be repeated here.

S604: The vehicle controller operates the second device in the vehicle to adjust the temperature in the vehicle.

In the embodiment of the present application, the specific implementation method of step S604 is as described in S504 above, which will not be repeated here.

S605: The vehicle controller does not perform any operation.

Through the above process, the vehicle controller in the embodiment of the present application can determine the working state of the first device and the temperature inside the vehicle.
