Description

Technical Field

[0001] This application belongs to the field of battery technology, and in particular relates to a method, apparatus, automobile, and readable storage medium for preventing vehicle power depletion. Background Technology

[0002] With the development of science and technology, automobiles are equipped with more and more electronic functions. While these electronic functions bring users a better driving experience, they also pose a huge challenge to the power consumption of vehicle batteries.

[0003] When the vehicle battery's charge drops to a certain level, the vehicle may become completely depleted, preventing it from starting properly and potentially damaging the battery and reducing its lifespan. Therefore, it is necessary to prevent the vehicle from becoming completely depleted during use.

[0004] However, current methods for preventing vehicle battery depletion often have a significant impact on the user's driving experience. Summary of the Invention

[0005] This application provides a method, apparatus, automobile, and readable storage medium for preventing vehicle power loss, which can effectively avoid vehicle power loss while reducing the impact on the user's driving experience.

[0006] A first aspect of this application provides a method for preventing vehicle power failure, the method comprising:

[0007] Obtain the remaining power of the vehicle's battery, and the number of times each preset vehicle function has been activated within the preset mileage recently traveled by the vehicle.

[0008] When the remaining power of the vehicle battery is within a preset power range, the target vehicle function that needs to be turned off is determined based on the number of times each preset vehicle function has been used, and the target vehicle function is turned off.

[0009] A second aspect of this application also provides a device for preventing vehicle power failure, the device comprising:

[0010] The acquisition unit is used to acquire the remaining power of the vehicle battery and the number of times each preset vehicle function has been used in the preset mileage recently traveled by the vehicle.

[0011] The shutdown unit is used to determine, based on the number of times each preset vehicle function has been used, the target vehicle function that needs to be shut down when the remaining charge of the vehicle battery is within a preset charge range, and then shut down the target vehicle function.

[0012] A third aspect of this application provides an automobile, including a battery, a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the computer program, when executed by the processor, implements the steps of the method for preventing vehicle power depletion described in the first aspect.

[0013] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method for preventing vehicle power depletion described in the first aspect.

[0014] In this embodiment, by obtaining the remaining power of the vehicle battery and the number of times each preset vehicle function has been used within the preset mileage recently driven by the vehicle, and when the remaining power of the vehicle battery is within a preset power range, the target vehicle function that needs to be turned off is determined based on the number of times each preset vehicle function has been used, and the target vehicle function is turned off. This allows the vehicle to combine the remaining power of the vehicle battery with the user's usage of each preset vehicle function, and selectively disable the use of certain vehicle functions, rather than directly disabling all or some electronic functions on the vehicle. This effectively avoids the occurrence of vehicle battery depletion while reducing the impact on the user's driving experience. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] Normally, when a vehicle is not running, such as when a user parks the vehicle and uses it to listen to music or turn on the air conditioning, the battery power will be quickly depleted. When the vehicle battery power drops to a certain level, the vehicle may become completely depleted, causing the vehicle to fail to start normally. It may even damage the vehicle battery and reduce its lifespan. Therefore, it is necessary to prevent the vehicle from becoming completely depleted.

[0022] Currently, methods to prevent vehicle battery depletion often have a significant impact on the user's driving experience.

[0023] For example, some related technologies, to prevent vehicle battery depletion, directly disable all or some electronic functions of the vehicle when the remaining battery power drops to a certain level. This involves shutting down high-power electronic devices to reduce battery consumption and avoid battery depletion. However, these high-power electronic devices may be frequently used and unwanted by the user, while disabling less frequently used, low-power electronic devices is often preferable. Therefore, this method of directly disabling all or some electronic functions when the remaining battery power drops to a certain level undoubtedly has a significant impact on the user's driving experience.

[0024] Based on this, embodiments of this application provide a method, apparatus, automobile, and readable storage medium for preventing vehicle battery depletion. By acquiring the remaining power of the vehicle battery and the number of times each preset vehicle function has been used within the preset mileage recently driven by the vehicle, and when the remaining power of the vehicle battery is within a preset power range, the method determines the target vehicle function that needs to be turned off based on the number of times each preset vehicle function has been used, and turns off the target vehicle function. This allows the vehicle to combine the remaining power of the vehicle battery with the user's usage of each preset vehicle function to selectively disable the use of certain vehicle functions, rather than directly disabling all or some electronic functions on the vehicle. This effectively avoids the occurrence of vehicle battery depletion while reducing the impact on the user's driving experience.

[0025] To better illustrate the technical solution of this application, examples are provided below.

[0026] like Figure 1 The diagram shown is a schematic representation of the implementation process of a method for preventing vehicle battery drain provided in an embodiment of this application. This method for preventing vehicle battery drain can be executed by a device configured on the vehicle to prevent vehicle battery drain. The vehicle can be a pure electric vehicle or a hybrid electric vehicle containing a battery, and this application does not limit this.

[0027] Specifically, the method for preventing vehicle battery drain provided in this application embodiment can be implemented using the following steps 101 to 102:

[0028] Step 101: Obtain the remaining power of the vehicle battery and the number of times each preset vehicle function has been used in the preset mileage of the vehicle's most recent driving.

[0029] Optionally, in some embodiments of this application, such as Figure 2 As shown, the remaining power of the battery 22 detected by the power detection sensor 21 can be sent to the body controller 23 via the LIN bus, so that the body controller 23 can obtain the remaining power of the vehicle battery in real time.

[0030] Optionally, in some embodiments of this application, such as Figure 2 As shown, the body controller 23 can obtain the working status of the electronic devices 24 corresponding to each preset vehicle function connected on the CAN bus through the CAN bus, and count the number of times each preset vehicle function is operated based on the working status of the electronic devices 24 corresponding to the preset vehicle function, so as to obtain the number of times each preset vehicle function is operated in the preset mileage recently traveled by the vehicle.

[0031] The specific value of the preset mileage can be set at the time of vehicle manufacturing based on practical experience or obtained from the configuration data input by the user. This application does not impose any restrictions on this.

[0032] Optionally, in some embodiments of this application, the preset mileage can be 100km or 200km.

[0033] In this embodiment of the application, the aforementioned preset vehicle function can be an electronic function that requires the user to actively activate it.

[0034] For example, in some embodiments of this application, the aforementioned preset vehicle functions may include one or more of the following functions: seat ventilation and heating, seat massage, front nozzle heating, front wiper heating, interior ambient lighting, exterior light show, high-speed wipers, trunk lighting, central control screen brightness adjustment, speaker volume adjustment, rear defrosting, rearview mirror heating, air conditioning, low-speed wipers, rear wiper function, front fog lights, rear fog lights, low beam headlights, high beam headlights, daytime running lights, rearview mirror ground lights, door lights, door handle lights, reversing lights, cornering lights, front window washer, rear window washer, cargo box lighting, navigation, radio, voice recognition, and Bluetooth music; this application does not limit these.

[0035] Step 102: When the remaining power of the vehicle battery is within the preset power range, determine the target vehicle function that needs to be turned off among the preset vehicle functions based on the number of times each preset vehicle function has been used, and turn off the target vehicle function.

[0036] In this embodiment, the number of times each preset vehicle function is operated within the vehicle's most recent preset mileage is used to represent the frequency with which the user uses each preset vehicle function in a recent period. This frequency can reflect the user's usage preferences and habits in a recent period. Therefore, this application determines the target vehicle function to be turned off based on the number of times each preset vehicle function is operated when the remaining power of the vehicle battery is within a preset power range. This is determined based on the user's usage preferences or habits. Therefore, turning it off can minimize the impact on the user's driving experience in order to prevent the vehicle from running out of power.

[0037] It should be noted that, in the embodiments of this application, step 102 above, turning off the target vehicle function may include turning off the electronic devices belonging to the target vehicle function among the vehicle functions that have been turned on, and prohibiting the subsequent turning on of the electronic devices corresponding to the target vehicle function, that is, prohibiting the use of the target vehicle function.

[0038] Optionally, in some embodiments of this application, the preset power range may include one or more sub-preset power ranges, and each sub-preset power range may be set with a corresponding number of working times threshold.

[0039] Accordingly, in step 102 above, when the remaining power of the vehicle battery is within a preset power range, the target vehicle function that needs to be turned off is determined based on the number of times each preset vehicle function is operated. This can be achieved in the following way: when the remaining power of the vehicle battery is within a target sub-preset power range of one or more of the above sub-preset power ranges, the preset vehicle function whose number of operations is less than or equal to the threshold number of operations corresponding to the target sub-preset power range is determined as the target vehicle function that needs to be turned off.

[0040] Optionally, in this embodiment, each of the above-mentioned sub-preset power ranges can be sub-preset power ranges with consecutive values, and the larger the value of the sub-preset power range, the smaller the threshold for the number of working times.

[0041] For example, when the above-mentioned preset power range may include n sub-preset power ranges P1, P2, P3, ..., Pn whose values ​​decrease sequentially within the range, and when the threshold for the number of working times corresponding to P1 is X1, the threshold for the number of working times corresponding to P2 is X2, the threshold for the number of working times corresponding to P3 is X3, ..., the threshold for the number of working times corresponding to Pn is Xn, then X1 is greater than X2, X2 is greater than X3, and X3 is greater than Xn.

[0042] Specifically, in a practical application, when the aforementioned preset battery capacity range includes three sub-preset battery capacity ranges: 50% < SOC ≤ 60%, 40% < SOC ≤ 50%, and 35% < SOC ≤ 40%, and the threshold number of operations corresponding to the sub-preset battery capacity range 50% < SOC ≤ 60% is 5, the threshold number of operations corresponding to the sub-preset battery capacity range 40% < SOC ≤ 50% is 10, and the threshold number of operations corresponding to the sub-preset battery capacity range 35% < SOC ≤ 40% is the maximum number of operations threshold X, if the remaining battery capacity of the vehicle is within the target sub-preset battery capacity range of 50% < SOC ≤ 60%, then the vehicle can be... In the most recent preset mileage, preset vehicle functions that have been used 5 times or less are identified as target vehicle functions that need to be turned off. If the remaining charge of the vehicle battery is within the target sub-preset charge range of 40% < SOC ≤ 50%, then preset vehicle functions that have been used 10 times or less in the most recent preset mileage are identified as target vehicle functions that need to be turned off. If the remaining charge of the vehicle battery is within the target sub-preset charge range of 350% < SOC ≤ 40%, then preset vehicle functions that have been used X times or less in the most recent preset mileage are identified as target vehicle functions that need to be turned off.

[0043] Where X is a value determined based on practical experience, and the value of X is a large value, that is, a value that the number of times each preset vehicle function works in the preset mileage recently driven by the vehicle cannot reach. For example, the value of X can be 500 times or 1000 times.

[0044] In a practical application, when the aforementioned preset battery range includes three sub-preset battery ranges: 50% < SOC ≤ 60%, 40% < SOC ≤ 50%, and 35% < SOC ≤ 40%, and the threshold number of operations for the sub-preset battery range 50% < SOC ≤ 60% is 5, the threshold number of operations for the sub-preset battery range 40% < SOC ≤ 50% is 10, and the threshold number of operations for the sub-preset battery range 35% < SOC ≤ 40% is the maximum threshold X, then preset vehicle functions with fewer than or equal to 5 operations in the vehicle's most recently traveled preset mileage can be classified as Class C functions, and preset vehicle functions with more than 5 operations and less than or equal to 10 operations in the vehicle's most recently traveled preset mileage can be classified as Class B functions. In the preset mileage range, preset vehicle functions with a working frequency greater than 10 (i.e., a working frequency greater than 10 and less than X) are classified as Class A functions. Then, when the remaining charge of the vehicle battery is within the target sub-preset charge range of 50% < SOC ≤ 60%, Class C functions are identified as target vehicle functions that need to be turned off and are disabled. When the remaining charge of the vehicle battery is within the target sub-preset charge range of 40% < SOC ≤ 50%, Class B and Class C vehicle functions are identified as target vehicle functions that need to be turned off and are disabled. When the remaining charge of the vehicle battery is within the target sub-preset charge range of 35% < SOC ≤ 40%, Class A, Class B, and Class C vehicle functions, i.e., all preset vehicle functions, are identified as target vehicle functions that need to be turned off and are disabled.

[0045] To improve vehicle driving safety, optionally, in some embodiments of this application, such as Figure 3 As shown, in step 102 above, turning off the target vehicle function can be achieved by using the following steps 301 to 302.

[0046] Step 301: Obtain the vehicle's current power level.

[0047] Step 302: If the vehicle's current power position is ON, determine the target delay time based on the remaining power and the vehicle's current average current consumption, and after delaying the target delay time, turn off the target vehicle function.

[0048] It should be noted that the vehicle's power settings generally include the following four positions: START, ON, OFF, and ACC.

[0049] The START position, or engine start position, is used to start the engine. After the engine starts, the vehicle's power switch will generally return to the ON position. When the vehicle's power switch is ON, all electronic devices on the vehicle can be used, and this is the position the vehicle is in when driving normally. When the vehicle's power switch is OFF, the entire vehicle is in a turned-off state, and all electronic devices on the vehicle cannot be used. When the vehicle's power switch is ACC, some electronic devices on the vehicle can be used, such as the radio and cigarette lighter, and these devices will consume battery power.

[0050] Therefore, based on the above analysis, in practical applications, we only need to consider how to prevent the vehicle from running out of power when the vehicle's power supply is in the ON or ACC position.

[0051] Since the vehicle is stationary when its power supply is in the ACC position, the electronic devices the user is using will not affect the safe operation of the vehicle. Therefore, in some embodiments of this application, when the vehicle's current power supply is in the ACC position, the target vehicle function can be turned off directly during the process of performing step 102 above, without delay, so as to let the user know the working status of the vehicle battery in a timely manner.

[0052] When the vehicle's current power position is ON, the vehicle may be in motion, and the target vehicle function may be related to improving vehicle driving safety. For example, the target vehicle function may be high-speed wipers, rear defrost, heated rearview mirrors, low-speed wipers, rear wiper function, front fog lights and / or rear fog lights. Therefore, in order to improve vehicle driving safety, during the process of turning off the target vehicle function in step 102, the target delay time can be determined based on the remaining battery power and the vehicle's current average current consumption, and the target vehicle function can be turned off after the target delay time.

[0053] Optionally, in some embodiments of this application, in the process of determining the target delay time based on the remaining power and the current average current consumption of the vehicle in step 302, the remaining power of the vehicle battery can be subtracted from the lower limit of the preset power range corresponding to the remaining power, and then divided by the current average current consumption of the vehicle to obtain the target delay time.

[0054] For example, when the aforementioned preset power range includes three sub-preset power ranges: 50% < SOC ≤ 60%, 40% < SOC ≤ 50%, and 35% < SOC ≤ 40%, and the remaining power of the vehicle battery is 45%, and the vehicle's current average current consumption is 10A, since 45% is within the sub-preset power range of 40% < SOC ≤ 50%, the target delay time T = (45% - 40%) / 10 = 0.005h can be obtained by subtracting the lower limit of the preset power range corresponding to the remaining power from the remaining power of the vehicle battery and dividing by the vehicle's current average current consumption.

[0055] Among them, the vehicle's current average current consumption can be determined by, for example Figure 2 The power detection sensor 21 shown sends data to the body controller 23 via the LIN bus.

[0056] In this embodiment, the target delay time is calculated by combining three parameters: the remaining power of the vehicle battery, the lower limit of the preset power range corresponding to the remaining power, and the current average current consumption of the vehicle, making the target delay time more reasonable.

[0057] Optionally, in some embodiments of this application, in order to prevent some electronic devices that are in use from being suddenly turned off without the user's knowledge, and to further improve the user's driving experience, a function shutdown prompt message can be output on the vehicle's central control screen before the target vehicle function is turned off.

[0058] For example, in such Figure 2 The central control screen 25 of the vehicle shown outputs voice prompts and / or text prompts that include the target delay duration and the types of target vehicle functions that need to be turned off. This allows users to have some awareness of the current average current consumption of the vehicle based on the length of the target delay duration. Furthermore, it helps users determine whether some or all target vehicle functions need to be turned off in advance to extend the target delay duration.

[0059] Optionally, in the above embodiments, since all preset vehicle functions need to be turned off when the vehicle's current power position is ON and the vehicle's remaining battery power is in the sub-preset battery range with the smallest battery value among the one or more sub-preset battery ranges, the vehicle's ON power can be directly cut off after the target delay time (e.g., by controlling...). Figure 2 The ON position power relay 26 of the vehicle shown is disconnected, which de-energizes all preset vehicle functions and activates the turn signal indicator (e.g., controls such as...). Figure 2The turn signal 27 flashes 3 times to remind the user that the vehicle battery has low remaining power and that it is necessary to prevent the vehicle from running out of power. This helps to avoid problems such as insufficient voltage that prevents the vehicle from starting properly, thus reducing the number of repair requests from the user.

[0060] In this embodiment, by obtaining the remaining power of the vehicle battery and the number of times each preset vehicle function has been used within the preset mileage recently driven by the vehicle, and when the remaining power of the vehicle battery is within a preset power range, the target vehicle function that needs to be turned off is determined based on the number of times each preset vehicle function has been used, and the target vehicle function is turned off. This allows the vehicle to combine the remaining power of the vehicle battery with the user's usage of each preset vehicle function, and selectively disable the use of certain vehicle functions, rather than directly disabling all or some electronic functions on the vehicle. This effectively avoids the occurrence of vehicle battery depletion while reducing the impact on the user's driving experience.

[0061] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions. In some embodiments of this application, certain steps may be performed in other orders.

[0062] like Figure 4 The diagram shown is a structural schematic of a device 400 for preventing vehicle power loss provided in an embodiment of this application. This device for preventing vehicle power loss can be configured on the aforementioned vehicle and may include an acquisition unit 401 and a shutdown unit 402.

[0063] The acquisition unit 401 is used to acquire the remaining power of the vehicle battery and the number of times each preset vehicle function has been used in the preset mileage of the vehicle's most recent driving.

[0064] The shut-off unit 402 is used to determine the target vehicle function that needs to be shut down among the preset vehicle functions based on the number of times each preset vehicle function has been operated when the remaining power of the vehicle battery is within a preset power range, and then shut down the target vehicle function.

[0065] Optionally, in some embodiments of this application, the preset power range includes one or more sub-preset power ranges, each sub-preset power range being set with a corresponding operating frequency threshold; the shutdown unit 402 is further configured to:

[0066] When the remaining charge of the vehicle battery is within a target sub-preset charge range of one or more sub-preset charge ranges, the preset vehicle functions whose number of operation times is less than or equal to the threshold number of operation times corresponding to the target sub-preset charge range are identified as target vehicle functions that need to be turned off.

[0067] Optionally, in some embodiments of this application, the closing unit 402 is further configured to:

[0069] If the vehicle's current power setting is ON, the target delay time is determined based on the remaining power and the vehicle's current average current consumption, and the target vehicle function is turned off after the target delay time.

[0070] Optionally, in some embodiments of this application, the closing unit 402 is further configured to:

[0071] Subtract the lower limit of the preset power range corresponding to the remaining power from the remaining power, and then divide by the current average current consumption to obtain the target delay time.

[0072] Optionally, in some embodiments of this application, the closing unit 402 is further configured to:

[0073] If the vehicle's current power position is ON, and the remaining battery level is in the sub-preset battery level range with the lowest battery value among one or more sub-preset battery level ranges, then after a target delay time, the vehicle's ON power will be cut off, and the turn signal will be activated as a warning.

[0074] Optionally, in some embodiments of this application, the closing unit 402 is further configured to:

[0075] Before disabling the target vehicle's function, a prompt message indicating that the function is disabled will be displayed on the vehicle's central control screen.

[0076] Optionally, in some embodiments of this application, the closing unit 402 is further configured to:

[0077] If the vehicle's current power setting is ACC, then the target vehicle's functions will be turned off directly.

A method for preventing vehicle power depletion, characterized in that, include: Obtain the remaining power of the vehicle's battery, and the number of times each preset vehicle function has been activated within the preset mileage recently traveled by the vehicle. When the remaining charge of the vehicle battery is within a preset charge range, the target vehicle function that needs to be turned off is determined based on the number of times each preset vehicle function has been used, and the target vehicle function is turned off. The preset power range includes one or more sub-preset power ranges, and each sub-preset power range is set with a corresponding working number threshold. When the remaining charge of the vehicle battery is within a preset charge range, the system determines the target vehicle function that needs to be turned off based on the number of times each preset vehicle function has been used, including: When the remaining charge of the vehicle battery is within a target sub-preset charge range of one or more sub-preset charge ranges, the preset vehicle functions whose number of operation times is less than or equal to the threshold number of operation times corresponding to the target sub-preset charge range are determined as the target vehicle functions that need to be turned off. The step of disabling the target vehicle's functions includes: Obtain the current power level of the vehicle; If the vehicle's current power setting is ON, then the target delay duration is determined based on the remaining power and the vehicle's current average current consumption, and after the target delay duration, the target vehicle function is turned off. If the vehicle's current power setting is ACC, then the target vehicle's functions will be directly turned off.

2. The method for preventing vehicle power failure as described in claim 1, characterized in that, The step of determining the target delay duration based on the remaining battery power and the vehicle's current average current consumption includes: The target delay time is obtained by subtracting the lower limit of the preset power range corresponding to the remaining power from the remaining power and then dividing by the current average current consumption.

3. The method for preventing vehicle power failure as described in claim 2, characterized in that, The method for preventing vehicle power loss also includes: If the vehicle's current power position is ON, and the remaining battery power is in the sub-preset battery range with the smallest battery value among the one or more sub-preset battery ranges, then after a target delay period, the vehicle's ON power is cut off, and the turn signal is activated as a warning.

4. The method for preventing vehicle power failure as described in any one of claims 1-3, characterized in that, Before disabling the target vehicle function, the method for preventing vehicle power loss further includes: The system displays a message indicating that the function is off on the vehicle's central control screen.

A device for preventing vehicle power loss, characterized in that, The device for preventing vehicle power loss includes: The acquisition unit is used to acquire the remaining power of the vehicle battery and the number of times each preset vehicle function has been used in the preset mileage recently traveled by the vehicle. The shutdown unit is used to determine the target vehicle function that needs to be shut down among the preset vehicle functions based on the number of times each preset vehicle function has been operated when the remaining power of the vehicle battery is within a preset power range, and then shut down the target vehicle function. The preset power range includes one or more sub-preset power ranges, and each sub-preset power range is set with a corresponding working number threshold. When the remaining charge of the vehicle battery is within a preset charge range, the system determines the target vehicle function that needs to be turned off based on the number of times each preset vehicle function has been used, including: When the remaining charge of the vehicle battery is within a target sub-preset charge range of one or more sub-preset charge ranges, the preset vehicle functions whose number of operation times is less than or equal to the threshold number of operation times corresponding to the target sub-preset charge range are determined as the target vehicle functions that need to be turned off. The step of disabling the target vehicle's functions includes: Obtain the current power level of the vehicle; If the vehicle's current power setting is ON, then the target delay duration is determined based on the remaining power and the vehicle's current average current consumption, and after the target delay duration, the target vehicle function is turned off. If the vehicle's current power setting is ACC, then the target vehicle's functions will be directly turned off.
