Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a control method, a control device, a vehicle, and a storage medium for the sleep state of a vehicle in the field of vehicles. Background Art

[0002] With the continuous development of society, vehicles have entered thousands of households. New energy vehicles are favored by more and more users for their advantages of low usage cost, low pollution level, and easy maintenance. Currently, the vast majority of new energy vehicles on the market use power batteries as power units to provide driving energy.

[0003] Generally, when a new energy vehicle is not used for a long time, it will automatically enter the sleep mode. Since it is impossible to determine the parking duration of the vehicle, the battery management system, the vehicle controller, and each sub-controller of the new energy vehicle still maintain their corresponding working states and continue to work when the new energy vehicle is parked. However, as the parking time of the new energy vehicle is longer, the power consumption of the power battery is greater, and over time, the power of the power battery may even be exhausted. This may cause the situation that the new energy vehicle cannot be started when the user uses it again, resulting in a waste of power resources and affecting the user's vehicle use experience.

[0004] Therefore, there is an urgent need for a control method for the sleep state of a vehicle to reduce the waste of vehicle resources of new energy vehicles and improve the user's vehicle use experience. Summary of the Invention

[0005] The present application provides a control method, a control device, a vehicle, and a storage medium for the sleep state of a vehicle, and this method can reduce the waste of vehicle resources of new energy vehicles and improve the user's vehicle use experience.

[0006] In a first aspect, a control method for the sleep state of a vehicle is provided, and the method includes: determining the usage frequency of the target vehicle based on multiple historical usage times of the target vehicle; determining a first target duration and a battery power based on the usage frequency, where the first target duration is the shortest duration that the target vehicle should be continuously unused when entering the sleep state, and the battery power is the maximum remaining power of the power battery that the target vehicle should satisfy when entering the sleep state; controlling the target vehicle to enter the sleep state when the continuous unused duration of the target vehicle is greater than the first target duration and the first remaining power is less than the battery power.

[0007] In the above technical solution, by analyzing the historical usage time of the target vehicle, the vehicle usage frequency can be accurately determined, and based on the vehicle usage frequency, the shortest duration of continuous non-usage and the maximum remaining power of the power battery that should be satisfied when the target vehicle enters the sleep state can be determined. That is to say, the differential sleep trigger conditions (including the duration condition of continuous non-usage and the power condition of the vehicle) are dynamically set according to the vehicle usage frequency. Further, when the target vehicle currently meets the sleep trigger condition, the target vehicle is controlled to enter the sleep state. For example, for a vehicle with a high usage frequency, this method can shorten the sleep waiting duration and relax the power limit, which can avoid the energy consumption of frequent wake-up caused by premature sleep; for a vehicle with a low usage frequency, the sleep waiting duration can be extended and the power limit can be reduced, which can reduce the self-discharge of the battery and the power consumption of the system standby when the vehicle is parked for a long time. In addition, the adaptive sleep mechanism based on the vehicle usage frequency in this method can not only ensure the possibility of the user using the vehicle at any time (such as a vehicle with a high usage frequency maintaining a high remaining power), but also reduce the loss of vehicle resources through reasonable sleep, improve the cruising range stability of the vehicle, and enhance the user's vehicle usage experience.

[0008] In combination with the first aspect, in some possible implementation manners, based on multiple historical usage times of the target vehicle, the usage frequency of the target vehicle is determined, including: when the time interval between any adjacent historical usage times among the multiple historical usage times with the first target ratio is less than or equal to the first preset duration, it is determined that the usage frequency is using the vehicle every day, and the first preset duration is the duration corresponding to N days; when the time interval between any adjacent historical usage times among the multiple historical usage times with the second target ratio is greater than the first preset duration and less than or equal to the second preset duration, it is determined that the usage frequency is using the vehicle frequently, and the second preset duration is the duration corresponding to M days; when the time interval between any adjacent historical usage times among the multiple historical usage times with the third target ratio is greater than the second preset duration and less than or equal to the third preset duration, it is determined that the usage frequency is using the vehicle rarely, and the third preset duration is the duration corresponding to K days; when the time interval between any adjacent historical usage times among the multiple historical usage times with the fourth target ratio is greater than the third preset duration, it is determined that the usage frequency is not using the vehicle frequently; where N, M, and K are all positive integers, N is 1, and N is less than M, and M is less than K.

[0009] In the above technical solution, among the multiple historical usage times with the first target proportion, if the time interval between any two adjacent historical usage times is less than or equal to the duration corresponding to one day, it is determined as using the vehicle every day. This can classify the vehicle usage situations with very intensive usage times. For the multiple historical usage times with the second target proportion, when the time interval between adjacent historical usage times is greater than one day and less than or equal to the duration corresponding to M days, it is determined as frequently using the vehicle. This way of establishing an intermediate vehicle usage state between using the vehicle every day and using it less frequently can help distinguish users who, although not using the vehicle every day, still have a relatively high usage frequency. Among the multiple historical usage times with the third target proportion, when the time interval between adjacent historical usage times is greater than M days and less than or equal to the duration corresponding to K days, it is determined as rarely using the vehicle. This classification method can identify users who use the vehicle occasionally. Among the multiple historical usage times with the fourth target proportion, when the time interval between any two adjacent historical usage times is greater than the duration corresponding to K days, it is determined as frequently not using the vehicle. This helps distinguish users who do not use the vehicle for a long time. This solution for classifying usage frequencies based on the time intervals between historical usage times can accurately classify users with different vehicle usage frequencies. This helps better understand the vehicle usage habits of users, so as to customize different dormancy schemes for the vehicles of different users, and optimize the service management and resource allocation of the vehicles themselves.

[0010] Combined with the first aspect and the above implementation manner, in some possible implementation manners, based on this usage frequency, determining the first target duration and the battery power includes: based on this usage frequency, determining the original target duration and the original battery power; obtaining the ambient temperature at which the target vehicle is currently located; based on this ambient temperature, adjusting the original target duration and the original battery power to obtain the first target duration and the battery power.

[0011] In the above technical solution, through the usage frequency of the target vehicle, the shortest reference duration for which the target vehicle should be continuously unused when entering the dormancy state and the maximum reference remaining power of the power battery that the target vehicle should meet when entering the dormancy state are determined. Further, through the ambient temperature at which the target vehicle is currently located, the shortest reference duration and the maximum reference remaining power are adjusted. That is, the dormancy conditions of the target vehicle are dynamically adjusted through the ambient temperature, which can increase the accuracy of the first target duration and the battery power, and significantly improve the battery management efficiency and the utilization rate of the vehicle's overall energy.

[0012] Combined with the first aspect and the above implementation manners, in some possible implementation manners, based on the usage frequency, the original target duration and the original battery power are determined, including: when the usage frequency is driving the vehicle every day, determining that the original target duration is the first preset duration and determining that the original battery power is the first preset power; when the usage frequency is frequently driving the vehicle, determining that the original target duration is the second preset duration and determining that the original battery power is the second preset power; when the usage frequency is rarely driving the vehicle, determining that the original target duration is the third preset duration and determining that the original battery power is the third preset power; when the usage frequency is rarely using the vehicle, determining that the original target duration is the fourth preset duration and determining that the original battery power is the fourth preset power, the fourth preset duration being greater than the third preset duration; wherein, the first preset power is higher than the second preset power, the second preset power is higher than the third preset power, and the third preset power is higher than the fourth preset power.

[0013] In the above technical solution, the method dynamically adjusts the conditions for the target vehicle to enter the sleep state based on the usage frequency of the target vehicle. For high-frequency vehicle use (such as driving the vehicle every day), the minimum first preset duration for triggering sleep and the highest battery power are set, which can ensure that the vehicle responds quickly and has sufficient battery life. As the usage frequency decreases, the method gradually extends the shortest duration for triggering sleep (the second preset duration, the third preset duration, the fourth preset duration) and reduces the battery power, which enables the target vehicle to stay in the sleep state for a longer time to reduce energy consumption when the vehicle is used at a low frequency, while avoiding performance degradation caused by long-term high battery power storage of the power battery. The above method can balance the user experience and battery protection, that is, when the vehicle is used at a high frequency, the availability is guaranteed first, and when the vehicle is used at a low frequency, the battery health is optimized. This can not only extend the life of the power battery and reduce the maintenance cost, but also realize the intelligent management of the energy utilization efficiency through the differentiated sleep mechanism.

[0014] Combined with the first aspect and the above implementation manners, in some possible implementation manners, based on the ambient temperature, the original target duration and the original battery power are adjusted to obtain the first target duration and the battery power, including: when the ambient temperature is less than the first preset temperature, increasing the original battery power by the first power to obtain the battery power, and reducing the original target duration by the first duration to obtain the first target duration, the first power and the first duration being related to the ambient temperature and the first preset temperature; when the ambient temperature is greater than the second preset temperature, reducing the original battery power by the second power to obtain the battery power, and increasing the original target duration by the second duration to obtain the first target duration, the second power and the second duration being related to the ambient temperature and the second preset temperature, the second preset temperature being greater than the first preset temperature.

[0015] In the above technical solution, the method dynamically adjusts, according to the ambient temperature, the duration threshold of continuous non - use and the power threshold of the power battery that should be met when the target vehicle determined by the usage frequency enters the sleep state, which can achieve optimization in multiple aspects. In a low - temperature environment, appropriately increasing the power threshold and shortening the duration threshold can not only prevent the power battery from having too low remaining power due to self - discharge at low temperature, which may affect the subsequent startup of the target vehicle or battery health, but also reduce unnecessary standby energy consumption. In a high - temperature environment, reducing the power threshold and lengthening the duration threshold can make full use of the relatively stable battery characteristics at high temperature to balance the energy - saving requirements and usage convenience. Overall, through the intelligent adjustment mechanism of temperature perception, the above method can effectively improve the management accuracy of the power battery life, reduce the system risk under extreme temperatures, and at the same time take into account the availability of the target vehicle being woken up at any time and the energy - saving efficiency in the sleep state.

[0016] Combined with the first aspect and the above implementation manners, in some possible implementation manners, when the continuous non - use duration of the target vehicle is greater than the first target duration and the first remaining power is less than the battery power, controlling the target vehicle to enter the sleep state includes: based on the usage frequency, determining the target shutdown order of multiple in - vehicle devices, the operating frequency of the battery temperature control system, and the depth of the target vehicle entering the sleep state, where the power consumption levels of the target vehicle are different at different depths; when the continuous non - use duration is greater than the first target duration and the first remaining power is less than the battery power, controlling the target vehicle to enter the sleep state at this depth, and in this depth of sleep state, controlling the multiple in - vehicle devices to stop running according to the target shutdown order, and controlling the battery temperature control system to operate at this operating frequency.

[0017] In the above technical solution, the method dynamically adjusts the depth of the sleep state, the shutdown order of multiple in - vehicle devices, and the operating frequency of the battery temperature control system according to the usage frequency of the target vehicle, which can achieve beneficial effects in multiple aspects. Specifically, based on the depth level division and trigger conditions (the first target duration and battery power) of the sleep state in different usage scenarios, it can significantly reduce the static energy consumption of the target vehicle while ensuring basic functions, and extend the battery life and cruising range of the power battery. Secondly, specifically controlling the non - essential in - vehicle devices to stop running according to the shutdown order can avoid system failures that may be caused by disorderly power - off, and can improve the safety and reliability of the target vehicle in the sleep state. Moreover, adaptively adjusting the operating frequency in combination with the sleep depth can not only maintain the necessary battery health state in light sleep, but also reduce the temperature control energy consumption in deep sleep, achieving a balance between battery protection and energy saving. Through refined energy management, the method can optimize the resource utilization rate of the target vehicle during long - term idleness, and is especially suitable for the flexible adaptation of the power maintenance of the target vehicle to the user's usage habits.

[0018] Combined with the first aspect and the above implementation manners, in some possible implementation manners, based on the usage frequency, determine the target shutdown order of multiple in-vehicle devices when the target vehicle enters the sleep state, including: comparing the usage frequency with multiple sample usage frequencies, and determining, from the sample shutdown orders of the multiple in-vehicle devices corresponding to the multiple sample usage frequencies, the first shutdown order of the multiple in-vehicle devices when the target vehicle enters the sleep state; obtaining the usage times and usage durations of each in-vehicle device by the target user in the target vehicle within a target preset duration; determining a judgment basis from the usage times and the usage durations based on the device type of each in-vehicle device, and the judgment basis has a high degree of importance in the process of adjusting the shutdown order of the multiple in-vehicle devices; and adjusting the first shutdown order according to the judgment basis of each in-vehicle device to obtain the target shutdown order, and the judgment basis is positively correlated with the shutdown order of the in-vehicle device.

[0019] In the above technical solution, the method constructs a hierarchical in-vehicle device shutdown mechanism by combining the usage frequency of the target vehicle and the usage habits of the user for the in-vehicle devices. Specifically, the initial shutdown order is determined based on the usage frequency to ensure the basic energy efficiency. Furthermore, multi-dimensional personalized indicators such as the device type, the actual usage times and usage durations of the target user for the in-vehicle devices are introduced. Through an adaptive judgment basis selection mechanism, that is, focusing on the usage times when the device type is a view-only device, and focusing on the usage duration when the device type is a non-view-only device. The shutdown order is dynamically adjusted through the judgment basis, which can make the shutdown order inherit the group experience and accurately adapt to the individual behavior of the target user, so as to reduce the static power consumption while reducing the decline of the user experience caused by incorrect shutdown, and achieve the balance optimization between energy management and usage convenience.

[0020] Combined with the first aspect and the above implementation manners, in some possible implementation manners, the method further includes: determining a second target duration and a target wake-up operation for the target vehicle to switch from the sleep state to the fully awakened state based on the usage frequency; in response to a first wake-up operation on the target vehicle, determining whether the first wake-up operation matches the target wake-up operation; and when the first wake-up operation matches the target wake-up operation, controlling the target vehicle to switch from the sleep state to the fully awakened state within the second target duration.

[0021] In the above technical solution, the method dynamically adjusts the wake-up duration and wake-up operation for the target vehicle to switch from the sleep state to the fully awakened state based on the usage frequency of the target vehicle. When the target user initiates the first wake-up operation, the method can ensure the legality of the wake-up process through matching verification, thereby realizing on-demand wake-up control. On the one hand, it can optimize energy consumption, reduce the waste of electric energy caused by frequent or redundant wake-up of the target vehicle during low-frequency use, and at the same time improve the response speed by shortening the wake-up duration when the vehicle is used frequently. On the other hand, it can prevent mis-wake-up through operation matching and provide different wake-up speeds based on different usage habits, achieving a balance between energy efficiency optimization and user experience as a whole.

[0022] In a second aspect, a control device for the vehicle sleep state is provided. The device includes: a determination module, configured to: determine the usage frequency of the target vehicle based on a plurality of historical usage times of the target vehicle; determine a first target duration and a battery power based on the usage frequency, where the first target duration is the shortest duration that the target vehicle should be continuously unused when entering the sleep state, and the battery power is the maximum remaining power of the power battery that the target vehicle should satisfy when entering the sleep state; a control module, configured to control the target vehicle to enter the sleep state when the continuous unused duration of the target vehicle is greater than the first target duration and the first remaining power is less than the battery power.

[0023] In combination with the second aspect, in some possible implementation manners, the determination module is specifically configured to: determine that the usage frequency is daily vehicle use when the time interval between any two adjacent historical usage times among a plurality of historical usage times with a first target ratio is less than or equal to a first preset duration, where the first preset duration is the duration corresponding to N days; determine that the usage frequency is frequent vehicle use when the time interval between any two adjacent historical usage times among a plurality of historical usage times with a second target ratio is greater than the first preset duration and less than or equal to a second preset duration, where the second preset duration is the duration corresponding to M days; determine that the usage frequency is seldom vehicle use when the time interval between any two adjacent historical usage times among a plurality of historical usage times with a third target ratio is greater than the second preset duration and less than or equal to a third preset duration, where the third preset duration is the duration corresponding to K days; determine that the usage frequency is often not vehicle use when the time interval between any two adjacent historical usage times among a plurality of historical usage times with a fourth target ratio is greater than the third preset duration; where N, M, and K are all positive integers, N is 1, and N is less than M, and M is less than K.

[0024] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the determining module is specifically further configured to: determine an original target duration and an original battery power based on the usage frequency; obtain an ambient temperature at which the target vehicle is currently located; and adjust the original target duration and the original battery power based on the ambient temperature to obtain the first target duration and the battery power.

[0025] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the determining module is specifically further configured to: when the usage frequency is daily vehicle use, determine that the original target duration is the first preset duration and determine that the original battery power is the first preset power; when the usage frequency is frequent vehicle use, determine that the original target duration is the second preset duration and determine that the original battery power is the second preset power; when the usage frequency is rare vehicle use, determine that the original target duration is the third preset duration and determine that the original battery power is the third preset power; when the usage frequency is frequent non-vehicle use, determine that the original target duration is the fourth preset duration and determine that the original battery power is the fourth preset power, the fourth preset duration being greater than the third preset duration; wherein, the first preset power is higher than the second preset power, the second preset power is higher than the third preset power, and the third preset power is higher than the fourth preset power.

[0026] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the determining module is specifically further configured to: when the ambient temperature is less than the first preset temperature, increase the original battery power by the first power to obtain the battery power, and decrease the original target duration by the first duration to obtain the first target duration, the first power and the first duration being related to the ambient temperature and the first preset temperature; when the ambient temperature is greater than the second preset temperature, decrease the original battery power by the second power to obtain the battery power, and increase the original target duration by the second duration to obtain the first target duration, the second power and the second duration being related to the ambient temperature and the second preset temperature, the second preset temperature being greater than the first preset temperature.

[0027] Combined with the second aspect and the above implementation manners, in some possible implementation manners, the determining module is specifically further configured to determine, based on the usage frequency, a target shutdown sequence of multiple in-vehicle devices, an operating frequency of a battery temperature control system, and a depth of the target vehicle entering a sleep state when the target vehicle enters the sleep state, and power consumption levels of the target vehicle are different at different depths; the control module is specifically further configured to, when the continuous unused duration is greater than the first target duration and the first remaining power is less than the battery power, control the target vehicle to enter the sleep state at this depth, and in the sleep state at this depth, control the multiple in-vehicle devices to stop operating according to the target shutdown sequence, and control the battery temperature control system to operate at this operating frequency.

[0036] Next, the technical solutions in the present application will be clearly and elaborately described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B: "and / or" in the text is only a description of the association relationship between associated objects, indicating that there can be three relationships. For example, A and / or B may mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality of" means two or more than two.

[0037] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0038] Figure 1 It is a schematic diagram of a scenario for using a vehicle provided by an embodiment of the present application.

[0039] It should be understood that with the continuous development of society and the continuous enhancement of people's awareness of environmental protection, new energy vehicles have entered thousands of households, and different users have different usage requirements for new energy vehicles. For example, as Figure 1 shown, some users need to drive vehicle A to and from work frequently, and some users only use vehicle A on weekends or holidays.

[0040] Currently, when new energy vehicles are not used for a long time, they will automatically enter the sleep mode. Since it is impossible to determine the parking duration of new energy vehicles, the management system of new energy vehicles still maintains the corresponding working state and continues to work when the new energy vehicles are parked. However, as the parking time of new energy vehicles becomes longer, the power consumption of the power battery becomes greater, and over time, the power of the power battery may even be exhausted. This may cause the situation that the new energy vehicle cannot be started when the user uses it again, resulting in a waste of power resources and affecting the user's vehicle use experience.

[0041] To solve the above problems, this application proposes a control method for the vehicle sleep state to reduce the waste of vehicle resources of new energy vehicles and improve the user's vehicle use experience. For details, please refer to the following Figure 2 steps.

[0042] Figure 2 FIG. is a schematic flowchart of a control method for the vehicle sleep state provided by an embodiment of this application.

[0043] It should be understood that a control method for the vehicle sleep state provided by an embodiment of this application can be applied to a vehicle (such as vehicle A) as shown in Figure 1 . Specifically, this control method for the vehicle sleep state can be applied to the vehicle's vehicle control unit.

[0044] Exemplarily, as shown in Figure 2 , this method 200 includes the following steps 201 to step 203.

[0045] Step 201, the vehicle control unit determines the usage frequency of the target vehicle based on multiple historical usage times of the target vehicle.

[0046] It should be understood that the "target vehicle" in the above step 201 can be a new energy vehicle.

[0047] It should also be understood that in the above step 201, the "multiple historical usage times" refers to the time when the target vehicle was used in the historical time period before the current moment. The "usage frequency" is used to measure the usage intensity or vehicle use frequency of the target vehicle, that is, how often the vehicle is used. In some embodiments, the usage frequency includes using the vehicle every day, using the vehicle frequently, using the vehicle rarely, and not using the vehicle frequently. Among them, using the vehicle every day can be using the vehicle once every N days, using the vehicle frequently can be using the vehicle once every M days, using the vehicle rarely can be using the vehicle once every K days, and not using the vehicle frequently can be using the vehicle once every more than K days. N, M, and K are all positive integers, N is 1, and N is less than M, and M is less than K.

[0048] In some embodiments, M is 3 and K is 7.

[0049] In some embodiments, the method for determining multiple historical usage times of the target vehicle in step 201 includes: the vehicle control unit obtains the start time of each trip in multiple trips of the target vehicle from the driving recorder in the target vehicle, and determines the start time of each trip in the multiple trips as the multiple historical usage times; or, the vehicle control unit obtains the end time of each trip in multiple trips of the target vehicle from the driving recorder in the target vehicle, and determines the end time of each trip in the multiple trips as the multiple historical usage times; or, the vehicle control unit determines the intermediate time of each trip based on the start time and the end time of each trip, and determines the intermediate time of each trip in the multiple trips as the multiple historical usage times.

[0050] In a possible implementation, step 201 includes: when the time interval between any two adjacent historical usage times in the multiple historical usage times of the first target proportion is less than or equal to the first preset duration, the vehicle control unit determines that the usage frequency is using the vehicle every day, and the first preset duration is the duration corresponding to N days; when the time interval between any two adjacent historical usage times in the multiple historical usage times of the second target proportion is greater than the first preset duration and less than or equal to the second preset duration, the vehicle control unit determines that the usage frequency is using the vehicle frequently, and the second preset duration is the duration corresponding to M days; when the time interval between any two adjacent historical usage times in the multiple historical usage times of the third target proportion is greater than the second preset duration and less than or equal to the third preset duration, the vehicle control unit determines that the usage frequency is using the vehicle rarely, and the third preset duration is the duration corresponding to K days; when the time interval between any two adjacent historical usage times in the multiple historical usage times of the fourth target proportion is greater than the third preset duration, the vehicle control unit determines that the usage frequency is not using the vehicle frequently; where N, M, and K are all positive integers, N is 1, and N is less than M, and M is less than K.

[0051] It should be understood that the multiple historical usage times of the "first target proportion" or "second target proportion" or "third target proportion" or "fourth target proportion" in the above solution all refer to most of the multiple historical usage times. Generally, the first target proportion, the second target proportion, the third target proportion, and the fourth target proportion are relatively large and are used to describe most of the historical usage times. In some embodiments, at least two of the first target proportion, the second target proportion, the third target proportion, and the fourth target proportion are different. Optionally, the first target proportion is 0.8, the second target proportion is 0.7, the third target proportion is 0.75, and the fourth target proportion is 0.8.

[0052] It should also be understood that the "multiple historical usage times of the first target ratio", "multiple historical usage times of the second target ratio", "multiple historical usage times of the third target ratio", and "multiple historical usage times of the fourth target ratio" in the above solutions are all sorted in chronological order.

[0053] In the above technical solution, among the multiple historical usage times of the first target ratio, when the time interval between any two adjacent historical usage times is less than or equal to the duration corresponding to one day, it is determined that the vehicle is used every day. This is a relatively refined classification, which can classify the vehicle usage situations with very intensive usage times. For example, if a user uses the vehicle almost every day and the time interval between adjacent historical usage times is very short, the usage frequency can be accurately defined as using the vehicle every day. For the multiple historical usage times of the second target ratio, when the time interval between adjacent historical usage times is greater than one day and less than or equal to the duration corresponding to M days, it is determined that the vehicle is used frequently. This way of establishing an intermediate vehicle usage state between using the vehicle every day and using it less can help distinguish users who, although not using the vehicle every day, still have a relatively high usage frequency. For example, some users may use the vehicle every other day or once every two or three days. Among the multiple historical usage times of the third target ratio, when the time interval between adjacent historical usage times is greater than M days and less than or equal to the duration corresponding to K days, it is determined that the vehicle is used rarely. This classification method can identify users who use the vehicle occasionally. Among the multiple historical usage times of the fourth target ratio, when the time interval between any two adjacent historical usage times is greater than the duration corresponding to K days, it is determined that the vehicle is rarely used. This helps distinguish users who do not use the vehicle for a long time. This solution for classifying usage frequency based on the time interval between historical usage times can accurately classify users with different vehicle usage frequencies. This helps better understand the vehicle usage habits of users, so as to customize different sleep schemes for the vehicles of different users, and optimize the service management and resource allocation of the vehicles themselves.

[0054] Step 202, the vehicle controller determines a first target duration and a battery power based on this usage frequency. The first target duration is the shortest duration that the target vehicle should be continuously unused when entering the sleep state, and the battery power is the maximum remaining power of the power battery that the target vehicle should meet when entering the sleep state.

[0055] It should be understood that in the above step 202, the "first target duration" is the shortest duration condition (the shortest duration condition for triggering sleep) that the target vehicle needs to meet when it wants to enter the sleep state. The duration here refers to the duration that the target vehicle is continuously unused. Among them, the first target duration is characterized by days or hours. The "battery power" is the maximum power condition that the target vehicle needs to meet when it wants to enter the sleep state. The power here refers to the remaining power of the power battery in the target vehicle. Among them, the battery power is characterized by a percentage (%).

[0056] In a possible implementation, the vehicle controller in step 202 determines the first target duration and the battery power based on the usage frequency, including: the vehicle controller determines the original target duration and the original battery power based on the usage frequency; the vehicle controller obtains the ambient temperature at which the target vehicle is currently located; the vehicle controller adjusts the original target duration and the original battery power based on the ambient temperature to obtain the first target duration and the battery power.

[0057] It should be understood that the "original target duration" in the above solution is the shortest duration that the target vehicle should be continuously unused when entering the sleep state determined only by the usage frequency, and the original target duration may not be very accurate. The "original battery power" in the above solution is the maximum remaining power of the power battery that the target vehicle should satisfy when entering the sleep state determined only by the usage frequency, and the original battery power may not be very accurate.

[0058] In the above technical solution, the shortest reference duration that the target vehicle should be continuously unused when entering the sleep state and the maximum reference remaining power of the power battery that the target vehicle should satisfy when entering the sleep state are determined by the usage frequency of the target vehicle. Further, the shortest reference duration and the maximum reference remaining power are adjusted based on the ambient temperature at which the target vehicle is currently located. That is, the sleep condition of the target vehicle is dynamically adjusted by the ambient temperature, which can increase the accuracy of the first target duration and the battery power, and significantly improve the battery management efficiency and the utilization rate of the vehicle's energy.

[0059] In a possible implementation, the vehicle controller determines the original target duration and the original battery power based on the usage frequency, including: when the usage frequency is daily vehicle use, determining the original target duration as the first preset duration and determining the original battery power as the first preset power; when the usage frequency is frequent vehicle use, determining the original target duration as the second preset duration and determining the original battery power as the second preset power; when the usage frequency is rare vehicle use, determining the original target duration as the third preset duration and determining the original battery power as the third preset power; when the usage frequency is rarely vehicle use, determining the original target duration as the fourth preset duration and determining the original battery power as the fourth preset power, where the fourth preset duration is greater than the third preset duration; where the first preset power is higher than the second preset power, the second preset power is higher than the third preset power, and the third preset power is higher than the fourth preset power.

[0060] It should be understood that in the above solution, the "first preset duration" is 24 hours. In some embodiments, when the second preset duration corresponds to M days and M is 3, the second preset duration is 72 hours. When the third preset duration corresponds to K days and K is 7, the third preset duration is 7 days, and the fourth preset duration is a duration greater than 7 days.

[0061] It should also be understood that in some embodiments, the first preset battery level is 80%, the second preset battery level is 70%, the third preset battery level is 60%, and the fourth preset battery level is 50%.

[0062] In the above technical solution, the method dynamically adjusts the conditions for the target vehicle to enter the sleep state based on the usage frequency of the target vehicle (using the vehicle every day, frequently using the vehicle, rarely using the vehicle, and rarely not using the vehicle). For high-frequency usage scenarios (such as using the vehicle every day), the minimum first preset duration and the highest battery level for triggering sleep are set, which can ensure that the vehicle responds quickly and has sufficient battery life. As the usage frequency decreases, the method gradually extends the shortest duration for triggering sleep (the second preset duration, the third preset duration, the fourth preset duration) and reduces the battery level, which enables the target vehicle to stay in the sleep state for a longer time to reduce energy consumption when the vehicle is used less frequently, while avoiding performance degradation caused by long-term high battery levels in the power battery. The above method can balance the user experience and battery protection, that is, when the vehicle is used frequently, availability is prioritized, and when the vehicle is used less frequently, battery health is optimized. This can not only extend the life of the power battery and reduce maintenance costs, but also achieve intelligent management of energy utilization efficiency through a differentiated sleep mechanism.

[0063] In a possible implementation, the vehicle control unit adjusts the original target duration and the original battery level based on the ambient temperature to obtain the first target duration and the battery level, including: when the ambient temperature is less than the first preset temperature, the vehicle control unit increases the original battery level by a first battery level to obtain the battery level, and reduces the original target duration by a first duration to obtain the first target duration, where the first battery level and the first duration are related to the ambient temperature and the first preset temperature; when the ambient temperature is greater than the second preset temperature, the vehicle control unit reduces the original battery level by a second battery level to obtain the battery level, and increases the original target duration by a second duration to obtain the first target duration, where the second battery level and the second duration are related to the ambient temperature and the second preset temperature, and the second preset temperature is greater than the first preset temperature.

[0064] It should be understood that in the above solution, the "first preset temperature" is a lower ambient temperature. In some embodiments, the first preset temperature is 1°. The "second preset temperature" is a higher ambient temperature. In some embodiments, the second preset temperature is 39°.

[0065] In the above technical solution, the method dynamically adjusts, according to the ambient temperature, the duration threshold for continuous non - use and the power threshold of the power battery that should be met when the target vehicle enters the sleep state, which is determined by the usage frequency, and can achieve optimization in multiple aspects. In a low - temperature environment, appropriately increasing the power threshold and shortening the duration threshold can not only prevent the power battery from having too low remaining power due to self - discharge at low temperature, which may affect the subsequent start - up of the target vehicle or the battery health, but also reduce unnecessary standby energy consumption. In a high - temperature environment, reducing the power threshold and extending the duration threshold can make full use of the relatively stable battery characteristics at high temperature to balance the energy - saving requirement and the usage convenience. Overall, the above method can effectively improve the management accuracy of the power battery life, reduce the system risk under extreme temperatures, while taking into account the availability of the target vehicle being woken up at any time and the energy - saving efficiency in the sleep state through an intelligent adjustment mechanism based on temperature perception.

[0066] In some embodiments, the method for determining the first power and the first duration includes: the vehicle controller determines the deviation amplitude of the ambient temperature relative to the first preset temperature; the vehicle controller determines the product of the original battery power and the deviation amplitude as the first power; the vehicle controller determines the product of the original target duration and the deviation amplitude as the first duration.

[0067] In some embodiments, the method for determining the second power and the second duration includes: the vehicle controller determines the increase amplitude of the ambient temperature relative to the second preset temperature; the vehicle controller determines the product of the original battery power and the increase amplitude as the second power; the vehicle controller determines the product of the original target duration and the increase amplitude as the second duration.

[0068] Step 203, when the continuous non - use duration of the target vehicle is greater than the first target duration and the first remaining power is less than the battery power, the vehicle controller controls the target vehicle to enter the sleep state.

[0069] It should be understood that in the above step 203, the "continuous non - use duration" refers to the duration when the target vehicle is in a stationary state continuously when it is not started. The "first remaining power" refers to the current remaining power of the target vehicle.

[0070] It should also be understood that the "target vehicle enters the sleep state" in the above step 203 means that the target vehicle enters a low - power mode. In the low - power mode, most of the in - vehicle devices in the target vehicle (such as the overhead ceiling screen and the voice output device, etc.) stop working, and only the necessary systems (such as the anti - theft system) are maintained. This can prevent the target vehicle from running out of power due to long - term parking, thereby protecting the life of the power battery.

[0071] In some embodiments, the method for determining the continuous unused duration of the target vehicle in step 203 includes: the vehicle control unit (VCU) detects whether the target vehicle is in a target state at every preset duration, and determines the number of times the target vehicle is in the target state, where the target state is the state that the target vehicle is not started and stationary; the VCU subtracts the first numerical value from the number of times to obtain a second numerical value; the VCU determines the product of the second numerical value and the preset duration as the continuous unused duration.

[0072] It should be understood that the "first numerical value" in the above solution is 1.

[0073] In some embodiments, after step 203, the method 200 further includes: when the continuous unused duration of the target vehicle is less than or equal to the first target duration and the first remaining power is greater than or equal to the battery power, the VCU controls the target vehicle not to enter the sleep state.

[0074] The following describes the specific process of "the target vehicle enters the sleep state".

[0075] In a possible implementation, step 203 includes: the VCU determines the target shutdown sequence of multiple in-vehicle devices, the operating frequency of the battery temperature control system, and the depth of the target vehicle entering the sleep state based on the usage frequency. The power consumption levels of the target vehicle are different at different depths; when the continuous unused duration is greater than the first target duration and the first remaining power is less than the battery power, the VCU controls the target vehicle to enter the sleep state at this depth, and controls the multiple in-vehicle devices to stop operating in accordance with the target shutdown sequence in the sleep state at this depth, and controls the battery temperature control system to operate at this operating frequency.

[0076] It should be understood that generally, when the target vehicle enters the sleep state, in-vehicle display screens, voice output devices, ambient lights, power-related controllers, adjustment devices of in-vehicle devices, air conditioning devices, and various detection sensors in the target vehicle will stop operating. Among them, the power-related controllers include the vehicle control unit (VCU), battery management system, motor controller, and in-vehicle charging communication controller, and the adjustment devices of in-vehicle devices include seat heating devices, steering wheel heating devices, and rearview mirror adjustment devices. Since different users have different usage requirements for in-vehicle devices, when different vehicles enter the sleep state, multiple in-vehicle devices can be controlled to turn off or stop operating in different sequences.

[0077] It should also be understood that in the above solution, the "battery temperature control system" is used to manage the temperature of the power battery during charging, discharging, and standby processes. The battery temperature control system can dynamically adjust the operating frequency based on changes in the ambient temperature to ensure that the temperature of the power battery is maintained within the optimal temperature range. The "depth of the target vehicle entering the sleep state" refers to the division of the low-power mode entered by the target vehicle in terms of power consumption levels. For example, the sleep state includes a shallow sleep state and a deep sleep state. The power consumption level in the shallow sleep state is higher (relatively higher power consumption) than that in the deep sleep state.

[0078] It should also be understood that the "target vehicle entering the deep sleep state" in the above solution refers to the target vehicle entering the sleep state corresponding to the power consumption level of this depth.

[0079] In the above technical solution, the method dynamically adjusts the depth of the sleep state, the shutdown order of multiple in-vehicle devices, and the operating frequency of the battery temperature control system based on the usage frequency of the target vehicle, which can achieve beneficial effects in multiple aspects. Specifically, based on the depth level division and trigger conditions (the first target duration and battery power) of the sleep state in different usage scenarios, it is possible to significantly reduce the static power consumption of the target vehicle while ensuring basic functions, and extend the battery life and endurance of the power battery. Secondly, specifically controlling the non-essential in-vehicle devices to stop operating according to the shutdown order can avoid system failures that may be caused by disorderly power-off, and can improve the safety and reliability of the target vehicle when it is in the sleep state. Moreover, adaptively adjusting the operating frequency in combination with the sleep depth can not only maintain the necessary battery health state during shallow sleep, but also reduce the temperature control power consumption during deep sleep, achieving a balance between battery protection and energy conservation. Through refined energy management, this method can optimize the resource utilization rate of the target vehicle during long-term idle periods, and is especially suitable for the flexible adaptation of the power maintenance of the target vehicle to the user's usage habits.

[0080] In a possible implementation, the vehicle controller determines the target shutdown order of multiple in-vehicle devices when the target vehicle enters the sleep state based on this usage frequency, including: the vehicle controller compares this usage frequency with multiple sample usage frequencies, and determines the first shutdown order of multiple in-vehicle devices when the target vehicle enters the sleep state from the sample shutdown orders of multiple in-vehicle devices corresponding to the multiple sample usage frequencies; the vehicle controller obtains the usage times and usage durations of each in-vehicle device by the target user in the target vehicle within the target preset duration; the vehicle controller determines the judgment basis from the usage times and the usage durations based on the device type of each in-vehicle device, and this judgment basis has a high degree of importance in the process of adjusting the shutdown order of the multiple in-vehicle devices; the vehicle controller adjusts the first shutdown order according to the judgment basis of each in-vehicle device to obtain the target shutdown order, and this judgment basis is positively correlated with the shutdown position of the in-vehicle device.

[0081] It should be understood that in the above solution, the difference in the "sample shutdown order of multiple in-vehicle devices" is only affected by the usage frequency. The "device type of the in-vehicle device" is used to distinguish the duration of an in-vehicle device during one use. In some embodiments, the device type includes a view-only device and a non-view-only device. The view-only device has a very short duration during one use, and this duration is usually less than a fifth preset duration. In some embodiments, the fifth preset duration is 1 second. The non-view-only device has a longer duration during one use, usually greater than a sixth preset duration. In some embodiments, the sixth preset duration is 2 minutes.

[0082] It should also be understood that the "judgment basis" in the above solution is the number of uses or the usage duration.

[0083] It should also be understood that the "judgment basis is positively correlated with the shutdown position of the in-vehicle device" in the above solution means that: the more the number of uses, the more backward the shutdown position; the fewer the number of uses, the more forward the shutdown position; the longer the usage duration, the more backward the shutdown position; the shorter the usage duration, the more forward the shutdown position.

[0084] In the above technical solution, the method constructs a hierarchical in-vehicle device shutdown mechanism by combining the usage frequency of the target vehicle and the user's usage habits of the in-vehicle device. Specifically, the initial shutdown order is determined based on the usage frequency to ensure basic energy efficiency. Furthermore, multi-dimensional personalized indicators such as the device type, the actual number of uses and the usage duration of the target user for the in-vehicle device are introduced. Through an adaptive selection mechanism based on the judgment basis, that is, focusing on the number of uses when the device type is a view-only device, and focusing on the usage duration when the device type is a non-view-only device. The shutdown order is dynamically adjusted based on the judgment basis, which can make the shutdown order inherit group experience and accurately adapt to the individual behavior of the target user, so as to reduce the static power consumption while reducing the decline in user experience caused by incorrect shutdown, and achieve a balanced optimization between energy management and usage convenience.

[0085] In some embodiments, the view-only device includes at least one of an hour hand for displaying time and an instrument panel for displaying vehicle basic information such as vehicle speed, engine speed, or fuel quantity. Generally, the duration of a user using the hour hand once is very short. For example, when viewing the hour hand once to obtain the time, the duration is 0.5 s.

[0086] In some embodiments, the non-view-only device includes at least one of an air conditioning device, a voice output device, a ceiling-mounted screen, an ambient light, and a seat heating device.

[0087] In some embodiments, the vehicle controller determines a judgment basis from the usage times and the usage durations based on the device types of the respective in-vehicle devices, including: for any target in-vehicle device among the multiple in-vehicle devices, when the device type of the target in-vehicle device is a view-only device, the vehicle controller determines the usage times as the judgment basis; when the device type of the target in-vehicle device is a non-view-only device, the vehicle controller determines the usage duration as the judgment basis.

[0088] In some embodiments, the vehicle controller adjusts the first shutdown order according to the judgment basis of each in-vehicle device to obtain the target shutdown order, including: when the device types of the multiple in-vehicle devices include view-only devices, the vehicle controller adjusts the first shutdown order in ascending order of the usage times to obtain the target shutdown order; when the device types of the multiple in-vehicle devices include non-view-only devices, the vehicle controller adjusts the first shutdown order in ascending order of the usage durations to obtain the target shutdown order; when the device types of the multiple in-vehicle devices include the view-only devices and the non-view-only devices, the vehicle controller adjusts the shutdown positions corresponding to the view-only devices in the first shutdown order in ascending order of the usage times, and adjusts the shutdown positions corresponding to the non-view-only devices in the first shutdown order in ascending order of the usage durations to obtain the target shutdown order.

[0089] Figure 3 It is a schematic diagram for determining the target shutdown order of multiple in-vehicle devices provided by an embodiment of the present application.

[0090] Exemplarily, as Figure 3 shown, when the target vehicle enters the sleep state, the first shutdown order of 5 in-vehicle devices is device 3, device 1, device 2, device 4, and device 5. The usage durations of the target user for these 5 in-vehicle devices within the target preset duration are 7, 7, 6, 6, and 5 respectively, and the usage times of the target user for these 5 in-vehicle devices within the target preset duration are 1, 3, 2, 4, and 5 respectively.

[0091] For non-view-only devices (device 3 and device 4, Figure 3 marked with a round frame in the figure), the shutdown positions of device 3 and device 4 in the first shutdown order are not generated in ascending order of the usage durations. Therefore, it is necessary to swap the shutdown positions of device 3 and device 4, that is, the shutdown position of device 4 is ahead of that of device 3.

[0092] For view-only devices (device 1, device 2, and device 5, Figure 3(marked with a square box), in this first shutdown sequence, the shutdown positions of device 1 and device 2 are not generated in the order from the least to the most usage times. Therefore, it is necessary to swap the shutdown positions of device 1 and device 2, that is, the shutdown position of device 2 is earlier than that of device 1.

[0093] Therefore, the target shutdown sequence of these 5 vehicle-mounted devices is device 4, device 2, device 1, device 3, and device 5.

[0094] In some embodiments, the vehicle controller determines the operating frequency of the battery temperature control system when the target vehicle enters the sleep state based on this usage frequency, including: when the usage frequency is daily vehicle use, the vehicle controller determines that the operating frequency is the first frequency; when the usage frequency is frequent vehicle use, the vehicle controller determines that the operating frequency is the second frequency; when the usage frequency is rare vehicle use, the vehicle controller determines that the operating frequency is the third frequency; when the usage frequency is frequent non-vehicle use, the vehicle controller determines that the operating frequency is the fourth frequency, the first frequency is greater than the second frequency, the second frequency is greater than the third frequency, and the third frequency is greater than the fourth frequency.

[0095] In some embodiments, the vehicle controller determines the depth of the target vehicle entering the sleep state based on this usage frequency, including: when the usage frequency is daily vehicle use, the vehicle controller determines that the depth is the first depth; when the usage frequency is frequent vehicle use, the vehicle controller determines that the depth is the second depth; when the usage frequency is rare vehicle use, the vehicle controller determines that the depth is the third depth; when the usage frequency is frequent non-vehicle use, the vehicle controller determines that the depth is the fourth depth, the power consumption level corresponding to the first depth is higher than the power consumption level corresponding to the second depth, the power consumption level corresponding to the second depth is higher than the power consumption level corresponding to the third depth, and the power consumption level corresponding to the third depth is higher than the power consumption level corresponding to the fourth depth.

[0096] The process of "after the target vehicle enters the sleep state, determining the wake-up strategy of the target vehicle" is described as follows.

[0097] In a possible implementation, after the vehicle controller controls the target vehicle to enter the sleep state, the method 200 further includes: the vehicle controller determines the second target duration and the target wake-up operation for the target vehicle to switch from the sleep state to the fully awakened state based on this usage frequency; the vehicle controller determines whether the first wake-up operation for the target vehicle matches the target wake-up operation in response to the first wake-up operation for the target vehicle; in the case where the first wake-up operation matches the target wake-up operation, the vehicle controller controls the target vehicle to switch from the sleep state to the fully awakened state within the second target duration.

[0098] It should be understood that the "fully awakened state" in the above solution means that all systems and devices in the target vehicle are activated and in a normal working state.

[0099] In the above technical solution, the method dynamically adjusts the wake-up duration and wake-up operation for the target vehicle to switch from the sleep state to the fully awakened state according to the usage frequency of the target vehicle. When the target user initiates the first wake-up operation, it can ensure the legality of the wake-up process through matching verification, and then achieve on-demand wake-up control. On the one hand, it can optimize energy consumption, reduce the waste of electric energy caused by frequent or redundant wake-up of the target vehicle during low-frequency use, and at the same time improve the response speed by shortening the wake-up duration when the vehicle is used frequently; on the other hand, it can prevent mis-wake-up through operation matching and provide different wake-up speeds based on different usage habits, achieving a balance between energy efficiency optimization and user experience as a whole.

[0100] In some embodiments, the vehicle control unit determines the second target duration and the target wake-up operation for the target vehicle to switch from the sleep state to the fully awakened state based on the usage frequency, including: when the usage frequency is daily vehicle use, the vehicle control unit determines that the second target duration is the third duration and determines that the target wake-up operation is approaching the target vehicle; when the usage frequency is frequent vehicle use, the vehicle control unit determines that the second target duration is the fourth duration and determines that the target wake-up operation is touching the target vehicle; when the usage frequency is rare vehicle use, the vehicle control unit determines that the second target duration is the fifth duration and determines that the target wake-up operation is knocking on the target vehicle; when the usage frequency is rarely used vehicle, the vehicle control unit determines that the second target duration is the sixth duration and determines that the target wake-up operation is pressing the button to start the target vehicle, where the third duration is less than the fourth duration, the fourth duration is less than the fifth duration, and the fifth duration is less than the sixth duration.

[0101] The following describes the process of "charging the target vehicle after the target vehicle is fully awakened".

[0102] In some embodiments, after the vehicle control unit controls the target vehicle to switch from the sleep state to the fully awakened state within the second target duration, the method 200 further includes: the vehicle control unit determines the minimum remaining power and the charging mode when the target vehicle is charged based on the usage frequency; the vehicle control unit determines whether the second remaining power of the target vehicle is less than the minimum remaining power in response to a charging request for the target vehicle; in the case where the second remaining power is less than the minimum remaining power, the vehicle control unit controls to charge the target vehicle in the charging mode.

[0103] It should be understood that the "charging mode" in the above solution includes the slow charging mode and the fast charging mode.

[0104] In the above technical solution, the method dynamically sets the minimum remaining power and charging mode according to the usage frequency of the target vehicle, which can realize the personalized optimization of the charging strategy. For vehicles that are not used frequently, a lower minimum remaining power can be set to reduce the full-charge loss of the battery in the long term. For vehicles with high usage frequency, a higher minimum remaining power can be set to ensure that the target vehicle always has sufficient available power. This can avoid overcharging and deep discharging, extend the service life of the power battery, and improve the usage reliability. At the same time, by matching the charging mode with the usage frequency (for example, fast charging for high-frequency vehicles and slow charging for low-frequency vehicles), on the basis of ensuring charging efficiency and safety, the energy utilization efficiency can be optimized, the charging cost of the target user can be reduced, and thus multiple optimizations of battery health management, user experience, and reasonable resource allocation can be achieved.

[0105] In some embodiments, the vehicle controller determines the minimum remaining power and charging mode when the target vehicle is charging based on the usage frequency, including: when the usage frequency is daily vehicle use, the vehicle controller determines that the minimum remaining power is the third power and determines that the charging mode is the fast charging mode; when the usage frequency is frequent vehicle use, the vehicle controller determines that the minimum remaining power is the fourth power and determines the first charging times when the target vehicle uses the fast charging mode during a historical preset time period; when the first charging times is greater than or equal to the first preset times, the vehicle controller determines that the charging mode is the slow charging mode; when the first charging times is less than the first preset times, the vehicle controller determines that the charging mode is the fast charging mode; when the usage frequency is rare vehicle use, the vehicle controller determines that the minimum remaining power is the fifth power and determines the second charging times when the target vehicle uses the slow charging mode during a historical preset time period; when the second charging times is greater than or equal to the second preset times, the vehicle controller determines that the charging mode is the fast charging mode; when the second charging times is less than the second preset times, the vehicle controller determines that the charging mode is the slow charging mode; when the usage frequency is frequent non-vehicle use, the vehicle controller determines that the minimum remaining power is the sixth power and determines that the charging mode is the slow charging mode, the third power is greater than the fourth power, the fourth power is greater than the fifth power, the fifth power is greater than the sixth power.

[0106] In some embodiments, the third power is 50%, the fourth power is 40%, the fifth power is 30%, and the sixth power is 20%.

[0107] Figure 4 It is a schematic structural diagram of a control device for the vehicle sleep state provided by an embodiment of the present application.

[0108] Exemplarily, as Figure 4 shown, the device 400 includes:

[0109] Determination module 401 is configured to:

[0110] Based on multiple historical usage times of the target vehicle, determine the usage frequency of the target vehicle;

[0111] Based on the usage frequency, determine a first target duration and a battery power. The first target duration is the shortest duration that the target vehicle should be continuously unused when entering the sleep state, and the battery power is the maximum remaining power of the power battery that the target vehicle should meet when entering the sleep state;

[0114] Optionally, the determination module 401 is further specifically configured to: based on the usage frequency, determine an original target duration and an original battery power; obtain the ambient temperature at which the target vehicle is currently located; based on the ambient temperature, adjust the original target duration and the original battery power to obtain the first target duration and the battery power.

[0116] Optionally, the determining module 401 is further specifically configured to: when the ambient temperature is less than the first preset temperature, increase the original battery power by the first power to obtain the battery power, and decrease the original target duration by the first duration to obtain the first target duration, where the first power and the first duration are related to the ambient temperature and the first preset temperature; when the ambient temperature is greater than the second preset temperature, decrease the original battery power by the second power to obtain the battery power, and increase the original target duration by the second duration to obtain the first target duration, where the second power and the second duration are related to the ambient temperature and the second preset temperature, and the second preset temperature is greater than the first preset temperature.
