Technical Field

[0001] This application relates to the field of automotive technology, and more particularly to the field of automotive energy technology, specifically to a vehicle energy management method, device, equipment, and storage medium. Background Technology

[0002] With the increasing popularity of electric vehicles and the continuous improvement of in-car intelligence, more and more people prefer to use their vehicles as mobile spaces for rest and relaxation. Whether driving or waiting for extended periods, the vehicle's battery level and remaining driving range are still key concerns for users.

[0003] When users are waiting or resting in the car for a long time, it is especially important to ensure the comfort of the car interior while minimizing unnecessary energy consumption. Summary of the Invention

[0004] One of the purposes of this application is to provide a vehicle energy management method, device, equipment and storage medium to reduce unnecessary energy consumption while ensuring vehicle interior comfort when the vehicle is parked for a long time.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] According to a first aspect of this application, a vehicle energy management method is provided, comprising: a vehicle energy management device acquiring a user's activation operation for a long-term parking mode; and in response to the activation operation, shutting down electrical devices included in a preset functional device cluster. Further, the vehicle energy management device acquires the user's selected target duration for the long-term parking mode and air conditioning settings, the air conditioning settings including air conditioning mode and air conditioning temperature; and determines the vehicle's estimated power consumption based on the air conditioning mode, air conditioning temperature, outside temperature, and target duration; further determines the remaining power based on the real-time battery level and the estimated power consumption, and displays the remaining power. Further, in response to the user's confirmation operation regarding the remaining power, the vehicle energy management device controls the air conditioning to turn on.

[0007] Based on the aforementioned technical means, the vehicle energy management method provided in this application, upon receiving a user's activation operation for the long-term parking mode, shuts down the electrical equipment included in the preset functional device cluster to reduce vehicle energy consumption during parking. Based on the air conditioning settings corresponding to the activation operation, it calculates the remaining energy consumption after activating the air conditioning for the target duration. After the user confirms the remaining battery power, the air conditioning is activated to ensure in-vehicle comfort while the vehicle is parked. Furthermore, by providing the user with the remaining battery power, it helps the user understand the energy consumption of the long-term parking mode, allowing the user to adjust the duration of the long-term parking mode or replenish the battery promptly, avoiding any impact on the user's subsequent driving experience.

[0008] In one possible implementation, the vehicle energy management method further includes: the vehicle energy management device determining the vehicle's parking duration, which is the actual operating time of the long-term parking mode; and controlling the air conditioning to turn off when the parking duration exceeds the target on-time.

[0009] Based on the aforementioned technical means, this application can control the air conditioner to turn off after the vehicle's parking time exceeds the set target opening time, thereby avoiding prolonged operation and excessive battery power consumption.

[0010] In one possible implementation, the vehicle energy management method further includes: the vehicle energy management device controlling the air conditioner to turn off when the real-time battery charge value is less than a preset charge value.

[0011] Based on the aforementioned technical means, this application can control the air conditioning to turn off when the real-time battery charge value of the vehicle is less than the preset charge value, thereby preventing the vehicle battery charge from being too low and affecting the user's subsequent driving experience.

[0012] In one possible implementation, the vehicle energy management method further includes: if the vehicle does not exit the long-term parking mode within a first preset time period after the air conditioner is turned off, the vehicle energy management device controls the air conditioner to operate in the external circulation mode; and plays a preset prompt audio within a second preset time period.

[0013] Based on the aforementioned technical means, this application enables the monitoring of whether the vehicle has exited the long-term parking mode after the air conditioner is turned off. In order to ensure the safety of users inside the vehicle, the air conditioner is controlled to operate in the external circulation mode to ensure air circulation inside the vehicle, and a preset prompt audio is played to remind the user.

[0014] In one possible implementation, the vehicle energy management method further includes: in response to the user's operation to turn off the long-term parking mode, the vehicle energy management device controls the electrical equipment included in the preset functional device cluster to restore the state before the long-term parking mode was turned on.

[0015] Based on the aforementioned technical means, this application can restore the devices included in the preset functional device cluster to their state before the long-term parking mode was enabled after the user exits the long-term parking mode, without requiring the user to enable each device individually, thus improving user convenience.

[0016] In one possible implementation, before obtaining the user's operation to activate the long-term parking mode, the vehicle energy management method further includes: the vehicle energy management device determining whether the vehicle's power supply is on and whether the vehicle's gear is in the parking position; and if the power supply is on and the gear is in the parking position, allowing the user to activate the long-term parking mode.

[0017] Based on the aforementioned technical means, the vehicle energy management method provided in this application, by detecting the power status and vehicle gear position, avoids the inability to turn on the air conditioner when the power is off, thus affecting comfort, and prevents the vehicle from rolling away and causing safety accidents when the gear is not in the parking position, thereby ensuring the user's vehicle safety and driving experience.

[0018] In one possible implementation, when the power supply is on and the vehicle is in the parking position, the vehicle energy management method further includes: the vehicle energy management device determining the occupant status inside the vehicle when no user operation to activate the long-term parking module is detected, the occupant status indicating whether there is anyone inside the vehicle. Further, if the duration for which the occupant status indicates no one is inside the vehicle exceeds a third preset duration, the vehicle energy management device controls the power supply to switch to the off state.

[0019] Based on the above technical means, this application realizes that if there is no user in the vehicle when the user has not selected to enable the long-term parking mode, the vehicle will automatically shut down, preventing the vehicle from running out of power due to the user forgetting to lock the car.

The processing unit is also used to display the remaining power. The processing unit is also used to, in response to the user's confirmation operation regarding the remaining power, control the air conditioning to turn on.

[0024] In one possible implementation, the processing unit is further configured to, in response to the user's operation to turn off the long-term parking mode, control the electrical equipment included in the preset functional equipment cluster to restore the state before the long-term parking mode was turned on.

[0025] In one possible implementation, the determining unit is further configured to determine whether the vehicle's power supply is on and whether the vehicle's gear is in the parking position. The processing unit is further configured to allow the user to activate the long-term parking mode when the power supply is on and the gear is in the parking position.

[0026] In one possible implementation, the determining unit is further configured to determine the occupant status inside the vehicle when no user operation to activate the long-term parking module is received, wherein the occupant status indicates whether there is anyone inside the vehicle. The processing unit is further configured to control the power supply to switch to an off state when the duration of the occupant status indicating that no one is inside the vehicle exceeds a third preset duration.

[0027] According to a third aspect provided in this application, a vehicle-mounted device is provided, deployed in a vehicle. The vehicle-mounted device includes a memory and a processor, which are coupled together; the memory stores computer program code, which includes computer instructions; when the processor executes the computer instructions, the vehicle-mounted device executes the vehicle energy management method provided in the first aspect and any possible implementation thereof.

[0031] Therefore, the above-mentioned technical features of this application have the following beneficial effects:

[0032] (1) In the vehicle energy management method provided in this application, when the vehicle energy management device receives the user's activation operation for the long-term parking mode, it shuts down the electrical equipment included in the preset functional device cluster to reduce the vehicle's energy consumption in the parking state.

It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0045] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0046] In the description of the embodiments, unless otherwise stated, " / " means "or". For example, A / B can mean A or B. The "and / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" and "more than one" refer to two or more. The terms "first," "second," etc., do not limit the quantity or execution order, and "first," "second," etc., do not necessarily imply that they are different.

[0047] With the increasing popularity of electric vehicles and the continuous improvement of in-car intelligence, more and more people prefer to use their vehicles as mobile spaces for rest and relaxation. Whether driving or waiting for extended periods, the vehicle's battery level and remaining driving range remain key concerns for users. When users are waiting or resting in their cars for long periods, it is particularly important to minimize unnecessary energy consumption while ensuring in-car comfort.

[0048] To address the aforementioned issues, this application proposes a vehicle energy management method, apparatus, device, and storage medium. The vehicle energy management device acquires a user's activation operation for a long-term parking mode; and in response to the activation operation, shuts down electrical devices included in a preset functional device cluster. Further, the vehicle energy management device acquires the user's selected target duration for the long-term parking mode and the air conditioning settings, including the air conditioning mode and temperature; and determines the vehicle's estimated power consumption based on the air conditioning mode, air conditioning temperature, outside temperature, and target duration; further, it determines the remaining battery power based on the real-time battery level and the estimated power consumption, and displays the remaining battery power. Furthermore, in response to the user's confirmation of the remaining battery power, the vehicle energy management device controls the air conditioning to turn on.

[0049] In this way, in the vehicle energy management method provided in this application, when the vehicle energy management device receives the user's activation operation for the long-term parking mode, it shuts down the electrical equipment included in the preset functional device cluster to reduce vehicle energy consumption in the parking state. Based on the air conditioning settings corresponding to the activation operation, it calculates the remaining energy consumption after turning on the air conditioning for the target duration, and turns on the air conditioning after the user confirms the remaining battery power to ensure in-vehicle comfort when the vehicle is parked. Furthermore, by providing the user with the remaining battery power, it helps the user understand the energy consumption of the long-term parking mode, allowing the user to adjust the duration of the long-term parking mode or replenish the battery in time, avoiding impacting the user's subsequent driving experience.

[0050] Figure 1 This application discloses a vehicle energy management system. The vehicle energy management method provided in this embodiment can be applied to, for example, vehicles with energy management functions such as, energy management systems ... Figure 1 The vehicle energy management system shown is used to ensure in-vehicle comfort when the vehicle is in parking mode. Figure 1 As shown, the vehicle energy management system 10 includes a vehicle energy management device 11, an air conditioner 12, a controller 13 for preset functional devices, and a vehicle-mounted device 14.

[0051] It should be noted that the aforementioned vehicle energy management system 10, as well as the vehicle energy management device 11, air conditioner 12, controller 13 of preset function devices, and vehicle infotainment device 14 included in the vehicle energy management system 10, are all deployed in the same vehicle. The vehicle energy management device 11 is deployed in the vehicle infotainment device 14 and is connected to the air conditioner 12 and the controller 13 of the preset function devices through the vehicle infotainment device 14. The above connection relationship can be wired or wireless, and this application embodiment does not limit it in this way.

[0052] The vehicle energy management device 11 can be used to obtain the user's operation of activating the long-term parking mode on the vehicle infotainment device 14.

[0053] The vehicle energy management device 11 can also be used to shut down electrical equipment included in the preset functional device cluster via the controller 13 of the preset functional device in response to the received start operation.

[0054] The vehicle energy management device 11 can also be used to obtain the target operating duration of the long-term parking mode selected by the user and the air conditioning settings.

[0055] The air conditioning settings include air conditioning mode and air conditioning temperature. The air conditioning mode includes heating mode and cooling mode.

[0056] The vehicle energy management device 11 can also be used to determine the vehicle's estimated power consumption based on the air conditioning mode, air conditioning temperature, outside temperature, and target operating time.

[0057] The vehicle energy management device 11 can also be used to determine the remaining power based on the real-time power value of the battery on the vehicle and the estimated power consumption, and display the remaining power through the vehicle's infotainment system 14.

[0058] The vehicle energy management device 11 can also be used to control the air conditioning to turn on in response to a user's confirmation of the remaining battery power via the vehicle's infotainment system 14.

[0059] Figure 2 This is a flowchart illustrating a vehicle energy management method according to some exemplary embodiments. In some embodiments, the above-described vehicle energy management method can be applied to, for example... Figure 1 The vehicle energy management system 10 shown includes a vehicle energy management device 11. Hereinafter, this application will describe the vehicle energy management method by taking the application of the vehicle energy management method to the vehicle energy management device 11 as an example.

[0060] like Figure 2 As shown, the vehicle energy management method provided in this application includes the following steps S201-S206.

[0061] S201, The vehicle energy management device obtains the user's operation to activate the long-term parking mode.

[0062] As one possible implementation, the vehicle energy management device is based on the vehicle's infotainment system and obtains the user's activation operation for the long-term parking mode on the vehicle's infotainment system.

[0063] It should be noted that the user's operation to activate the long-term parking mode on the vehicle's infotainment system can be either a selection operation on the display screen of the vehicle's infotainment system or a voice control command received by the user through the voice recognition module of the vehicle's infotainment system. This application embodiment does not specifically limit this.

[0064] S202, In response to the activation operation, the vehicle energy management device shuts down the electrical equipment included in the preset functional equipment cluster.

[0065] Among them, the electrical equipment included in the preset functional equipment cluster includes, for example, augmented reality head-up display (AR-HUD) devices, sensor-activated unlocking devices, instruments, exterior lights, interior lights, central control display screen, autonomous driving domain control unit, driving recorder camera and other devices.

[0066] As one possible implementation, after the vehicle energy management device obtains the user's activation of the long-term parking mode based on the above step S201, it obtains the operating status of the devices included in the preset functional device cluster. Further, when the operating status of a device indicates that the device is running, the vehicle energy management device sends a long-term parking signal to the controller corresponding to that device, instructing the controller to switch the device's operating status to the off state.

[0067] For example, if the vehicle energy management device determines that the AR-HUD device is operating, it sends a long-term parking signal to the AR-HUD device controller, causing the AR-HUD device controller to turn off the AR-HUD device in response to the long-term parking signal. If the vehicle energy management device determines that the inductive unlocking device is operating, it sends a long-term parking signal to the inductive unlocking device controller, causing the inductive unlocking device controller to turn off the inductive unlocking device in response to the long-term parking signal.

[0068] Correspondingly, if the vehicle energy management device determines that the instrument panel, exterior lights, interior lights, central control display, autonomous driving domain control unit, and driving recorder are operating, it sends a long-term parking signal to the controller corresponding to each device, so that the controller corresponding to each device responds to the long-term parking signal and shuts down the corresponding device.

[0069] Understandably, turning off the AR-HUD device can save on its operating current consumption; turning off the inductive unlocking device can stop its radio frequency module from actively scanning outwards, thus saving on the dark current of the radio frequency module; turning off the instrument display can save on unnecessary power consumption caused by keeping the instrument display on for extended periods; turning off the control unit in the autonomous driving domain can reduce unnecessary power consumption of the autonomous driving control unit due to monitoring and detection; turning off the dashcam can reduce the power consumption of the camera, and so on.

[0070] S203, The vehicle energy management device obtains the target activation duration of the long-term parking mode selected by the user and the air conditioning settings.

[0071] The air conditioning settings include air conditioning mode and air conditioning temperature.

[0072] As one possible implementation, the vehicle energy management device obtains the duration and air conditioning parameters selected by the user when performing the operation to activate the long-term parking mode, determines the selected duration as the target activation duration, and determines the air conditioning mode and air conditioning temperature based on the selected air conditioning parameters.

[0073] For example, the target operating time can be 30 minutes, 1 hour, 3 hours, 6 hours, etc., and the air conditioning mode included in the air conditioning settings can be heating mode, cooling mode, heating internal circulation mode, heating external circulation mode, etc., and the air conditioning temperature can be 22 degrees, 25 degrees, 28 degrees, etc. This application embodiment does not specifically limit these.

[0074] S204. The vehicle energy management device determines the vehicle's estimated power consumption based on the air conditioning mode, air conditioning temperature, outside temperature, and target operating duration.

[0075] As one possible implementation, the vehicle management device acquires the outside temperature and determines a target temperature difference based on the air conditioning temperature and the outside temperature. Further, based on the air conditioning mode, air conditioning temperature, and the target temperature difference, the vehicle management device determines the power consumption per unit time corresponding to the target temperature difference when operating in that air conditioning mode and at that air conditioning temperature. Further, the vehicle energy management device determines the vehicle's estimated power consumption based on the power consumption per unit time and the target operating duration.

[0076] It should be noted that the mapping relationship between air conditioning mode, air conditioning temperature, temperature difference, and power consumption per unit time can be preset in the vehicle energy management device by the maintenance personnel of the vehicle energy management system. This application embodiment does not specifically limit this.

[0077] For example, the mapping relationship between air conditioning mode, air conditioning temperature, temperature difference, and power consumption per unit time can be shown in Table 1 below as a power consumption lookup table per unit time.

[0078] Table 1: Power Consumption per Unit Time Query Table

[0079]

[0080] For example, if the vehicle energy management device determines that the user has selected the air conditioning mode as cooling mode and the air conditioning temperature as 25 degrees, and the determined temperature difference is 5 degrees, then the vehicle energy management device determines that the power consumption per unit time is E7 when the air conditioning is running in cooling mode at 25 degrees and the temperature difference is 5 degrees.

[0081] Furthermore, if the target activation duration is A, then the vehicle energy management device determines the estimated power consumption = A * E7.

[0082] S205. The vehicle energy management device determines the remaining power based on the real-time power level of the vehicle's battery and the estimated power consumption, and displays the remaining power.

[0083] As one possible implementation, the vehicle energy management device requests the battery management device to obtain the current real-time battery level. Based on the estimated power consumption determined in step S204 above, it calculates the difference between the real-time battery level and the estimated power consumption, and determines the difference as the remaining battery level. Furthermore, the vehicle energy management device displays the remaining battery level for the user to confirm, and determine whether it is necessary to adjust the target duration of the long-term parking mode or to request additional power.

[0084] It should be noted that if the user is not satisfied with the remaining battery power and needs to readjust the long-term parking mode, the vehicle energy management device will re-execute the above step S204 after the user adjusts the target operating time or air conditioning settings, determine the estimated power consumption, and update the remaining battery power for the user to confirm after determining the estimated power consumption.

[0085] S206. The vehicle energy management device responds to the user's confirmation of the remaining battery power by controlling the air conditioning to turn on.

[0086] As one possible implementation, after the user confirms the remaining battery power, the vehicle energy management device determines that the user has confirmed the activation of the long-term parking mode with the target activation duration and the air conditioning settings, and controls the air conditioning to start and operate according to the air conditioning settings in step S203 above.

[0087] Understandably, in the vehicle energy management method provided in this application embodiment, in response to the user's operation of activating the long-term parking mode, the energy consumption of the vehicle during long-term parking is reduced by turning off the devices included in the preset function cluster, and the air conditioner is operated based on the air conditioner settings confirmed by the user and the target on-time, so as to ensure the comfort inside the vehicle.

[0088] In one design, to avoid excessive energy consumption when the vehicle is in long-term parking mode, the vehicle energy management method provided in this application embodiment, such as... Figure 3 As shown, it also includes S301-S302.

[0089] S301, The vehicle energy management device determines the vehicle's parking duration.

[0090] Among them, the parking duration is the actual running time of the long-term parking mode.

[0091] As one possible implementation, the vehicle energy management device starts timing after the vehicle enters long-term parking mode and determines the timing duration as the parking duration.

[0092] S302. The vehicle energy management device controls the air conditioning to turn off when the parking time exceeds the target on time.

[0093] As one possible implementation, the vehicle energy management device compares the parking duration determined in step S301 with the target operating duration determined in step S203. Furthermore, if the parking duration exceeds the target operating duration, the vehicle energy management device controls the air conditioning to shut off.

[0094] In some embodiments, to prevent the vehicle's energy from dropping too low, the vehicle energy management device acquires the real-time charge value of the vehicle's battery and controls the air conditioning to turn off when the real-time charge value of the battery is less than a preset charge value.

[0095] It should be noted that the preset power value can be set in advance by the maintenance personnel of the vehicle energy management system in the vehicle energy management device. For example, it can be 20%, 30%, or 10.8Ah, 12Ah, etc. This application embodiment does not make specific limitations on this.

[0096] In some embodiments, to prevent safety issues arising from the user falling asleep in the vehicle after the air conditioning is turned off, the vehicle energy management device determines whether the user exits the long-term parking mode within a first preset time period after the air conditioning is turned off.

[0097] Furthermore, if the vehicle does not exit the long-term parking mode within the first preset time period after the air conditioner is turned off, the vehicle energy management device controls the air conditioner to operate in the external circulation mode and plays a preset prompt audio within the second preset time period to remind the user to exit the long-term parking mode in time.

[0098] It should be noted that the first preset duration, the second preset duration, and the preset prompt audio can be preset in the vehicle energy management device by the operation and maintenance personnel of the vehicle energy management system. For example, the first preset duration can be 30 seconds, 1 minute, 2 minutes, etc., the second preset duration can be 3 minutes, 5 minutes, etc., and the preset prompt audio can be "Long-term parking mode has ended". This application embodiment does not make specific limitations on this.

[0099] In some embodiments, if the vehicle energy management device receives a user's operation to turn off the long-term parking mode, the vehicle energy management device responds to the user's operation to control the devices included in the preset functional device cluster to restore the state before the long-term parking mode was turned on after the vehicle exits the long-term parking mode.

[0100] It should be noted that after the vehicle energy management device activates the long-term parking mode, it stores the operating status of each device in the preset functional device cluster. When the long-term parking mode is exited, the operating status of each device is retrieved and switched to the operating status before the long-term parking mode was activated.

[0101] In one design, before obtaining the user's activation of the long-term parking mode, to ensure comfort and safety after activating the long-term parking mode, the vehicle energy management method provided in this application embodiment, such as... Figure 4 As shown, it also includes S401-S402.

[0102] S401, The vehicle energy management device determines whether the vehicle's power supply is on and whether the vehicle is in the parking gear.

[0103] The power status includes ON and OFF, and the parking gear is P.

[0104] As one possible implementation, the vehicle energy management device acquires the power supply position signal and the vehicle gear position signal. Based on whether the power supply position signal is ON, it determines whether the power supply is in the ON state. Based on whether the vehicle gear position signal is in the parking gear, it determines whether the vehicle gear is in the parking gear.

[0105] S402. When the vehicle energy management device is powered on and in the parking position, the user is allowed to activate the long-term parking mode.

[0106] As one possible implementation, when the vehicle energy management device is in the "on" state and the gear is in the "park" position, it enables the button for activating the long-term parking mode, allowing the user to activate the long-term parking mode via the button. Otherwise, it prevents the user from activating the long-term parking mode, thus avoiding the inability to turn on the air conditioning when the vehicle is powered off, which would affect comfort, and also preventing the vehicle from rolling away and causing a safety accident when the gear is not in the "park" position.

[0107] In some embodiments, if the power is on and the vehicle is in the parking position, and the vehicle energy management device does not detect any user activation of the long-term parking module, it determines the occupant status inside the vehicle, whereby the occupant status indicates whether there is anyone inside the vehicle. Further, if the occupant status indicates that no one is inside the vehicle for a duration exceeding a third preset duration, the vehicle energy management device controls the power to switch to the off state.

[0108] For example, the vehicle energy management device can determine the status of people inside the vehicle by detecting whether there are people inside the vehicle using an in-vehicle camera, or by obtaining whether there are people in the seats using pressure sensors installed on the seats. This application embodiment does not specifically limit this.

[0109] It should be noted that the third preset duration can be set in advance in the vehicle energy management device by the operation and maintenance personnel of the vehicle energy management system. For example, the third preset duration can be 15 minutes, 20 minutes, etc. This application embodiment does not specifically limit this.

[0110] It is understandable that in the vehicle energy management method provided in the embodiments of this application, by detecting the power status and vehicle gear position, it is possible to avoid the inability to turn on the air conditioner when the vehicle is powered off, which would affect comfort, and to prevent the vehicle from rolling away and causing a safety accident when the gear is not in the parking position, thus ensuring the user's vehicle safety and driving experience.

[0111] In one design, the flowchart for implementing the long-term parking mode of the vehicle energy management method provided in this application embodiment is as follows: Figure 5 As shown, it includes S501-S511.

[0112] S501, The vehicle energy management device determines whether the power supply is on and whether the vehicle is in the parking gear.

[0113] It should be noted that when the power is on and the vehicle is in the parking gear, the control panel for the long-term parking mode is enabled and can receive user input for the long-term parking mode.

[0114] Correspondingly, when the power is on and the vehicle is in park, the vehicle energy management device executes step S502.

[0115] S502, The vehicle energy management device receives the user's operation to activate the long-term parking mode.

[0116] S503, The vehicle energy management device shuts down the electrical equipment included in the preset function equipment cluster.

[0117] S504, Determine the air conditioning settings corresponding to the vehicle energy management device activation operation.

[0118] It should be noted that if the air conditioning setting corresponding to the operation is used to indicate whether the air conditioning is turned on, the vehicle energy management device executes step S505 when the air conditioning setting indicates that the air conditioning is turned on, and executes step S506 when the air conditioning setting indicates that the air conditioning is not turned on and the air conditioning is currently on.

[0119] S505, The vehicle energy management device controls the operation of the air conditioning based on the air conditioning settings corresponding to the activation operation.

[0120] S506, The vehicle energy management device controls the air conditioning to shut off.

[0121] S507, The vehicle energy management device determines whether the real-time battery charge value is less than or equal to the preset charge value.

[0122] It should be noted that when the real-time battery charge value is greater than the preset charge value, the vehicle energy management device executes step S509; when the real-time battery charge value is less than or equal to the preset charge value, the vehicle energy management device executes step S508.

[0123] S508, The vehicle energy management device determines whether the vehicle's parking duration is greater than or equal to the target activation duration.

[0124] It should be noted that when the vehicle's parking time is greater than or equal to the target activation time, the vehicle energy management device executes step S509; when the vehicle's parking time is less than the target activation time, it executes step S510.

[0125] S509. The vehicle energy management device turns off the heating or cooling function of the air conditioner and controls the air conditioner to operate in external circulation mode.

[0126] S510, The vehicle energy management device determines whether it has received a user's request to exit the long-term parking mode.

[0127] The exit operation includes entering an exit command or switching the vehicle's gear to non-parking gear. Exit commands include voice exit commands and central control exit commands.

[0128] It should be noted that after confirming that the user has exited the long-term parking mode, the vehicle energy management device executes step S511.

[0129] S511, The vehicle energy management device controls the electrical equipment included in the preset functional equipment cluster to restore the state before the long-term parking mode was activated.

[0130] It should be noted that the specific implementation of the vehicle energy management method described in steps S501-S511 above can be referred to the description in the above embodiments of this application, and will not be repeated here.
