[0002] The four-wheel drive system controller (hereinafter referred to as the "four-wheel drive controller") is the core component used to manage and distribute power in four-wheel drive vehicles. Its main function is to adjust the power distribution between the front and rear wheels in real time according to the vehicle's driving status, road conditions and the driver's operating requirements, so as to improve the vehicle's handling, stability and fuel economy.

[0003] Under normal circumstances, the four-wheel drive controller initiates a full-vehicle test when the engine is started to prevent abnormal operating conditions from affecting the four-wheel drive system and causing driving risks. However, in actual use, if the vehicle's electronic system is powered off and then back on for unusual reasons (such as a sudden battery power outage and reconnection), the four-wheel drive controller may mistakenly trigger a full-vehicle test. If the four-wheel drive controller is allowed to continue performing a full-vehicle test, the battery will quickly deplete, making it impossible for the vehicle to start normally.

[0005] Optionally, the hierarchical power consumption processing measures include first-level power consumption processing measures and second-level power consumption processing measures; wherein, the first-level power consumption processing measures are used to prompt the user to restart the four-wheel drive system according to a pre-configured prompt strategy through the vehicle's in-vehicle interactive system to end the abnormal power consumption state of the four-wheel drive controller; the second-level power consumption processing measures are used to automatically restart the four-wheel drive system to end the abnormal power consumption state of the four-wheel drive controller; the minimum timing time value of the timing interval corresponding to the second-level power consumption processing measures is greater than the maximum timing time value of the timing interval corresponding to the first-level power consumption processing measures. Optionally, the prompt strategy includes prompt content and / or prompt frequency.

[0006] Optionally, there are at least two first-level power consumption processing measures; when the prompt strategy includes prompt content, the prompt content of the first-level power consumption processing measures corresponding to the subsequent timing interval is higher in urgency than the first-level power consumption processing measures corresponding to the prior timing interval; when the prompt strategy includes prompt frequency, the prompt frequency of the first-level power consumption processing measures corresponding to the subsequent timing interval is higher than the first-level power consumption processing measures corresponding to the prior timing interval, and the minimum timing time value of the subsequent timing interval is greater than the maximum timing time value of the prior timing interval.

[0019] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this specification.

[0020] As previously mentioned, the four-wheel drive controller, as a core component in vehicle power distribution, requires a full vehicle test upon engine startup to ensure system safety. However, when the vehicle is reconnected after an abnormal battery power outage, the four-wheel drive controller may mistakenly trigger the test process without the engine starting, causing its quiescent current to increase significantly (from a normal level of less than 0.02A to 0.10A). If this condition persists, the four-wheel drive controller will rapidly deplete the battery charge, rendering the vehicle unable to start.

[0021] In order to solve the problem of abnormal power consumption of the four-wheel drive controller, this application proposes a vehicle control solution, which can monitor the power consumption status of the four-wheel drive controller in real time when the vehicle engine is not started, and start timing after monitoring that the four-wheel drive controller enters the abnormal power consumption state, so as to perform graded power consumption processing measures according to the difference in duration, thereby dynamically adjusting the intensity to intervene and end the abnormal power consumption state of the four-wheel drive controller.

[0022] Among them, the vehicle control solution of the present application includes a vehicle control method, device, vehicle and storage medium, and the respective embodiments are introduced in detail below.

[0023] Specifically, an embodiment of the present application provides a vehicle control method. Figure 1 FIG. 1 is a flow chart of the vehicle control method, including: S101 , when the engine of the vehicle is not started, monitoring the power consumption state of the four-wheel drive controller of the vehicle with the graded power consumption treatment measure.

[0024] As previously mentioned, the four-wheel drive controller typically performs vehicle inspection only when the engine is started. Therefore, under normal circumstances, the power consumption of the four-wheel drive controller when the engine is started will be significantly higher than when the engine is not started. In this embodiment, if the power consumption of the four-wheel drive controller is too high when the engine is not started, for example, close to the power consumption level when the engine is started, it can be determined to be an abnormal power consumption state. To this end, it is necessary to continuously monitor the power consumption of the four-wheel drive controller when the engine is not started.

[0025] As a feasible approach, this embodiment can evaluate the power consumption status of the four-wheel drive controller based on the quiescent current of the four-wheel drive controller. Quiescent current refers to the current consumed by the device itself, which can reflect the basic energy consumption of the device. Correspondingly, a preset threshold value can be set for the quiescent current value of the four-wheel drive controller to measure its normal power consumption level when the engine is not started. If the quiescent current value of the four-wheel drive controller reaches the preset threshold value, it is determined that the four-wheel drive controller has entered an abnormal power consumption state.

[0026] Typically, the quiescent current of the four-wheel drive controller is strictly controlled to below 0.02A when the engine is not started to avoid battery charging. To this end, this embodiment can set the preset threshold to 0.02A, or around 0.02A (e.g., 0.02 to 0.05A) to represent the maximum quiescent current value corresponding to the maximum power consumption state allowed for the four-wheel drive controller when the vehicle is not undergoing full vehicle testing. Taking 0.03A as an example, if the quiescent current of the four-wheel drive controller reaches 0.03A when the vehicle's engine is not started, it can be determined that it has entered an abnormal power consumption state.

[0027] Based on the above, this embodiment can also determine that the four-wheel drive controller has entered an abnormal power consumption state when the quiescent current value of the four-wheel drive controller reaches a preset threshold and persists for at least a certain period of time (e.g., 10 seconds). It should be understood that setting a duration can eliminate interference from instantaneous fluctuations in the quiescent current value, thereby improving the accuracy of the determination.

[0028] S102: If the four-wheel drive controller enters an abnormal power consumption state, the duration of the four-wheel drive controller in the abnormal power consumption state is timed; wherein the abnormal power consumption state is confirmed when the static current value of the four-wheel drive controller is greater than a preset current threshold.

[0029] The root cause of abnormal power consumption in the four-wheel drive controller is the erroneous triggering of the vehicle inspection process when the engine is not started, resulting in a persistently high quiescent current value and accelerated battery drain. To prevent this from leading to battery depletion, this embodiment uses the timing function of the vehicle's microcontroller unit (MCU) or onboard system to measure the duration of the four-wheel drive controller's abnormal power consumption. Based on the duration of the power consumption, a tiered power consumption treatment measure is implemented to intervene and end the abnormal power consumption state. In other words, as the duration of the abnormal power consumption state increases, the power consumption treatment measure implemented is adjusted accordingly, achieving a step-by-step intervention effect.

[0030] Specifically, if the user starts the engine while measuring the duration of an abnormal power consumption state, it is normal for the four-wheel drive controller to perform a full vehicle test. In this case, the state originally determined to be abnormal power consumption can be reclassified as normal power consumption, and monitoring of the four-wheel drive controller's power consumption status will be stopped. Simultaneously, this embodiment resets the timing mechanism (i.e., clears the accumulated duration timer to zero). After the engine is next shut down, monitoring of the four-wheel drive controller's power consumption status will resume, and whether to restart timing will be determined based on the monitored quiescent current value.

[0031] Furthermore, during the timing process, if the user proactively restarts the four-wheel drive system (powering the entire vehicle on and off), the four-wheel drive controller will be reset and exit the abnormal power consumption state. In this case, this embodiment can also reset the entire timing mechanism, ending the current timing and clearing the accumulated timing value. It should be noted that restarting the four-wheel drive system is not the same as starting the engine; the power consumption state of the four-wheel drive controller still needs to be continuously monitored. If it is determined again that the four-wheel drive controller has entered an abnormal power consumption state, the duration of the abnormal power consumption state needs to be re-timed.

[0032] In summary, when the user starts the engine or restarts the four-wheel drive system on their own, if the abnormal power consumption problem of the four-wheel drive controller is solved, this embodiment will immediately reset the timing mechanism to avoid erroneous triggering of graded power consumption processing measures due to accumulated timing. In addition, after the user operation, once it is confirmed that the engine is turned off, this embodiment will resume monitoring the power consumption status of the four-wheel drive controller. Once it is confirmed again that the four-wheel drive controller has an abnormal power consumption problem, the duration of the abnormal power consumption will be measured based on the reset timing mechanism. This design ensures that the system can flexibly respond to user operations and adjust the graded power consumption processing strategy, thereby avoiding unnecessary misoperations.

[0033] S103 , executing corresponding graded power consumption processing measures according to the timing interval to which the duration belongs; wherein different timing intervals correspond to different graded power consumption processing measures, and the graded power consumption processing measures are used to intervene and end the abnormal power consumption state of the four-wheel drive controller.

[0034] This embodiment dynamically implements a hierarchical intervention strategy based on the duration of abnormal power consumption to achieve a balance between battery power protection and user experience. Specifically, the hierarchical power consumption treatment measures are divided into: 1) First-level power consumption management measures: Used to prompt the user to restart the four-wheel drive system (powering on and off the entire vehicle) according to the pre-configured prompt strategy through the vehicle's in-vehicle interactive system (such as the vehicle computer and instrument cluster) to end the abnormal power consumption state of the four-wheel drive controller; 2) Second-level power consumption handling measure: used to automatically restart the four-wheel drive system to end the abnormal power consumption state of the four-wheel drive controller; the duration interval corresponding to the second-level power consumption handling measure is later than the first-level power consumption handling measure, that is, the minimum timing time value of the timing interval corresponding to the second-level power consumption handling measure is greater than the maximum timing time value of the timing interval corresponding to the first-level power consumption handling measure.

[0035] When the four-wheel drive controller is in an abnormal power consumption state, this embodiment first executes the first level power consumption treatment measure to attempt to manually restart the four-wheel drive system by the user. If the first level power consumption treatment measure is ineffective, the second level power consumption treatment measure is then executed to force an automatic restart of the four-wheel drive system.

[0036] The advantage of this hierarchical execution of power consumption processing measures is that in the early stage of battery power feeding caused by the four-wheel drive controller, the user is allowed to intervene to solve the problem as much as possible; but if the power feeding problem is still not solved, the system will restart the four-wheel drive system on behalf of the user to avoid aggravated battery power feeding, which will affect the normal use of the vehicle.

[0037] Based on the above, the first-level power consumption processing measure of this embodiment is not limited to one, and different first-level power consumption processing measures correspond to their own prompt strategies, specifically covering one or more of the following elements: 1) Prompt duration (e.g., 1 minute, 3 minutes, 10 seconds); 2) prompt frequency (e.g., single prompt, periodic repetitive prompt); 3) Prompt method (such as text prompt, voice prompt, vibration prompt, etc.); 4) Prompt content (such as text message, voice message).

[0038] It should be understood that in this embodiment, different first-level power consumption treatment measures can be assigned different prompt intensities by personalizing the elements of the above-mentioned prompt strategy. That is, on this basis, as the duration of the abnormal power consumption state increases, the prompt intensity of the corresponding first-level power consumption treatment measure can also be increased accordingly. For example: If the prompt strategy includes prompt content, the prompt content for the first-level power consumption treatment measure in the later timing interval should be more urgent than the first-level power consumption treatment measure in the earlier timing interval (the minimum time value in the later timing interval is greater than the maximum time value in the earlier timing interval). For example, using text prompts, the difference in prompt intensity can be reflected by emphasizing the tone and wording of the prompt text.

[0039] If the notification strategy includes notification frequency, the notification frequency of the first-level power consumption treatment measure corresponding to the later timing interval is higher than the first-level power consumption treatment measure corresponding to the earlier timing interval. Taking vibration notification as an example, the difference in notification intensity can be reflected by increasing the vibration frequency.

[0040] For ease of understanding, a specific implementation method is cited below for illustration.

[0041] This embodiment provides three different levels of power consumption processing measures according to the duration of abnormal power consumption states, as shown in the following table:

[0042] In the above table, the intervention level of the graded power consumption treatment measures in the first timing interval → the second timing interval → the third timing interval is gradually increased. Specifically: The first level of power consumption treatment measures corresponding to the first time interval focuses on: in the early stage of the four-wheel drive controller causing battery power loss, prompting the user to intervene and restart the four-wheel drive system with a prompt text in a suggestive tone. For example, the instrument panel may display a text message such as "The four-wheel drive controller is consuming abnormal power. Please try to restart the vehicle (power on and off the entire vehicle)"; The first level of power consumption management measures corresponding to the second time interval focuses on: prompting the user to intervene and restart the four-wheel drive system with a warning message in the early and middle stages of the four-wheel drive controller causing battery power loss. For example, the instrument panel will display a message such as "Abnormal power consumption of the four-wheel drive controller, please restart the vehicle as soon as possible."

[0043] The second-level power consumption treatment measure corresponding to the third timer interval focuses on forcibly restarting the four-wheel drive system if the battery charge problem persists and the vehicle is in safe conditions (e.g., vehicle speed = 0, gear in Park). Because it does not require user authorization, the second-level power consumption treatment measure has the highest intervention intensity. To avoid user discomfort caused by forced automatic restarts of the four-wheel drive system, the second-level power consumption treatment measure can use a countdown to restart the four-wheel drive system, and display a countdown reminder to the user on the instrument panel, such as "The four-wheel drive controller is consuming too much power. The four-wheel drive system will automatically restart in 10 seconds." This design aims to give users time to prepare and reduce operational disruption caused by sudden restarts. It also preserves the user's right to intervene during the countdown period, allowing them to restart the four-wheel drive system if they feel the wait time is too long.

[0044] As can be seen, this embodiment divides the handling measures into multiple levels according to the duration of the abnormal power consumption state. Initially, at least two first-level power consumption handling measures with configurable prompt strategies are used to gradually enhance the reminder for active user intervention (increasing the urgency of the prompt content and the frequency of prompts), thereby retaining user autonomy in the early stages of battery recharging. If the problem cannot be solved by the first-level power consumption handling measures, it is automatically upgraded to the second-level power consumption handling measures to force a restart of the four-wheel drive system to prevent excessive battery power consumption. This staged processing architecture coordinates the upfront prompt enhancement with the post-mandatory protection, ultimately achieving the dual goals of minimizing user intervention costs and maximizing battery power protection in the scenario of abnormal power consumption of the four-wheel drive controller.

[0045] The following describes the implementation process of the vehicle control method of this embodiment in conjunction with specific application scenarios.

[0046] This application scenario configures the following vehicle signals for the power consumption control of the four-wheel drive controller: Signal A: Vehicle engine status signal, used to indicate whether the engine is started.

[0047] Signal C: The static current signal of the four-wheel drive controller is used to indicate the size of the static current.

[0048] Signal D: timing signal of abnormal power consumption state of four-wheel drive controller, used to indicate the duration of abnormal power consumption state.

[0049] Signals B / E / F: corresponding to activation status signals of power consumption treatment measures 1, 2, and 3, respectively. The configurations of these three power consumption treatment measures are as follows: 1) Power consumption treatment measure 1 (first level power consumption treatment measure) Prompt content: "The four-wheel drive controller has abnormal power consumption, please try restarting the vehicle (suggestive tone)."

[0050] Prompt method: text prompt.

[0051] Prompt frequency: Single prompt to reduce interference to users.

[0052] Prompt time: 1 minute.

[0053] 2) Power consumption treatment measure 2 (first level power consumption treatment measure) Prompt content: "The four-wheel drive controller is consuming abnormal power. Please restart the vehicle as soon as possible" (in a warning tone) Prompt mode: text and voice prompts; Prompt frequency: Voice prompt is repeated every 30 seconds; Tip time: 3 minutes.

[0054] 3) Power consumption treatment measure 3 (second level power consumption treatment measure) Prompt content: "The four-wheel drive controller consumes too much power and will automatically restart in 10 seconds"; Prompt method: text prompt; Prompt frequency: once; Execution content: Force restart of the four-wheel drive system.

[0055] Correspondingly, refer to Figure 2 As shown, the process of the vehicle control method of this embodiment can be divided into the following stages: Phase 1: Monitoring the power consumption of the four-wheel drive controller In this stage, the engine status signal (signal A) must be continuously received.

[0056] When signal A indicates that the engine is not started, the static current value of the four-wheel drive controller is obtained through the vehicle's CAN bus, and the next stage of the process is executed.

[0057] When signal A indicates that the engine is started, stop acquiring signal C and wait until signal A indicates that the engine is not started.

[0058] Phase 2: Determine the abnormal power consumption of the four-wheel drive controller In this stage, when signal C indicates that the static current of the four-wheel drive controller is ≥0.03A and lasts for 10 seconds, it is determined that the four-wheel drive controller has entered an abnormal power consumption state.

[0059] After determining that the four-wheel drive controller has entered an abnormal power consumption state, if signal A changes to indicate engine start, the four-wheel drive system is determined to be in a normal power consumption state even if the static current is ≥0.03A, and the process returns to stage one.

[0060] Phase 3: Timing the duration of abnormal power consumption After determining that the four-wheel drive controller has entered the abnormal power consumption state, the duration of the abnormal power consumption state of the four-wheel drive controller is measured by a timer to generate a latest signal D.

[0061] During the timing process, if signal A changes to indicate engine start, the timing accumulation value of signal D is cleared and the process returns to stage 1.

[0062] In addition, during the timing process, if the user restarts the four-wheel drive system by powering on and off the vehicle, the timing accumulation value of signal D will be cleared and the process will return to stage two.

[0063] Phase 4: Execute graded power consumption treatment measures based on the duration of the abnormal power consumption state. If Signal D indicates a duration between 2 and 3 hours, Signal B is activated to implement Power Consumption Handling Measure 1: The vehicle's instrument panel displays a warning message, "Abnormal power consumption of the four-wheel drive controller. Please try restarting the vehicle." This prompt persists for one minute, followed by the deactivation of Signal B. If, while Signal B is active, the user restarts the four-wheel drive system by powering the vehicle on and off, Signal B is immediately deactivated, and the accumulated timer value for Signal D is cleared, returning to Phase 2. Furthermore, if, while Signal B is active, Signal A changes to indicate an engine start, Signal B is deactivated, and the accumulated timer value for Signal D is cleared, returning to Phase 1. When Signal D indicates a duration between 3 and 5 hours, Signal E is activated to implement Power Consumption Handling Measure 2: a warning message, "Abnormal power consumption of the four-wheel drive controller. Restart the vehicle as soon as possible," is displayed on the vehicle's instrument panel. A voice announcement is triggered every 30 seconds for three minutes. If the user restarts the four-wheel drive system by powering the vehicle on and off, Signal E is deactivated, the accumulated timer value for Signal D is cleared, and the process returns to Phase 2. Furthermore, if Signal A changes to indicate engine start while Signal E is active, Signal E is deactivated, the accumulated timer value for Signal D is cleared, and the process returns to Phase 1. After Signal D indicates a duration of 5 hours, a safety check is first performed to confirm that the vehicle is stationary and in Park. If the vehicle is confirmed to be stationary and in Park, Signal F is activated to implement power consumption treatment measure 3: "The four-wheel drive controller is consuming too much power and will automatically restart in 10 seconds" is displayed on the vehicle instrument panel. After the countdown ends, a command is sent to force the four-wheel drive controller to restart, restore its static current to below 0.02A, and clear the accumulated timer value of Signal D. During the 10-second countdown, if the user restarts the four-wheel drive system by powering the vehicle on and off, Signal F is immediately deactivated, the accumulated timer value of Signal D is cleared, and the process returns to Phase 2. Furthermore, during the 10-second countdown, if Signal A changes to indicate engine start, Signal F is deactivated, the accumulated timer value of Signal D is cleared, and the process returns to Phase 1. Through the above process, the vehicle control method of this embodiment covers the following abnormal scenarios:

[0064] In summary, the vehicle control method of this embodiment monitors the engine status (signal A) and the quiescent current of the four-wheel drive controller (signal C) in real time. When the engine is not started and the quiescent current remains ≥0.03A for more than 10 seconds, it identifies an abnormal power consumption state. It then initiates a timer for the abnormal power consumption state (signal D). Based on the duration of the abnormal power consumption state, a tiered intervention is dynamically implemented: within 2-3 hours, a single instrument panel prompt is sent to the user to restart the vehicle (signal B). If the user does not respond, a periodic voice and text message reminder is issued within 3-5 hours (signal E). Finally, a forced restart of the four-wheel drive controller is initiated after ≥5 hours of no response (signal F). This approach guides user intervention through a progressively more robust prompting strategy, while integrating a final safety check (vehicle stationary, park) to ensure the safety of the forced restart. Furthermore, this embodiment further considers user interaction by intelligently resetting the timer if the user starts the engine, restarts the four-wheel drive system, or otherwise prevents erroneous timer accumulation and the inadvertent triggering of power consumption measures. The entire solution can be implemented in the vehicle control unit through a program, and can be deployed through cloud upgrade technology for vehicles that have already left the factory. Since no hardware changes are required, it is highly practical.

[0065] It should be noted that the above content is only used to provide an illustrative introduction to the vehicle control method of this embodiment. In addition to the instrument and the vehicle computer, the first-level power consumption processing measures can also be prompted through other modules inside the vehicle, such as head-up display, electronic rearview mirror, and interior lights. In addition, the prompt strategy corresponding to each graded power consumption processing measure can also be flexibly set, and the setting objects are not limited to prompt duration, prompt frequency, prompt method, and prompt content. Moreover, as the duration of the abnormal power consumption state increases, the prompt method used can also be affected, thereby increasing the intervention intensity through a combination of multiple prompt methods. It should be understood that these foreseeable changes should fall within the scope of protection of this specification.

[0066] In addition, corresponding to Figure 1 In addition to the method shown, another embodiment of the present application further provides a vehicle control device. Figure 3 FIG. 3 is a schematic structural diagram of the vehicle control device 300, comprising: The monitoring module 310 is used to monitor the power consumption status of the four-wheel drive controller of the vehicle when the engine of the vehicle is not started.

[0067] The timing module 320 is used to time the duration of the four-wheel drive controller in the abnormal power consumption state if the four-wheel drive controller enters the abnormal power consumption state; wherein the abnormal power consumption state is confirmed when the static current value of the four-wheel drive controller is greater than a preset current threshold.

[0068] The execution module 330 is an execution module for executing a matching graded power consumption processing measure according to the timing interval to which the duration belongs; wherein different graded power consumption processing measures are pre-configured for different timing intervals, and the graded power consumption processing measures are used to intervene and end the abnormal power consumption state.

[0069] The vehicle control device of this embodiment can monitor the power consumption of the four-wheel drive controller in real time, even when the vehicle engine is not started. When the four-wheel drive controller is detected to be in an abnormal power consumption state, the device will time it and implement differentiated power consumption treatment measures based on the duration of the abnormal power consumption state. By dynamically adjusting the intervention intensity, the device can effectively end the abnormal power consumption state of the four-wheel drive controller, thereby preventing the four-wheel drive controller from depleting the battery power and causing the vehicle to fail to start.

[0070] Optionally, the preset current threshold is the maximum static current value that the four-wheel drive controller is allowed to reach when the whole vehicle detection is not performed.

[0071] Optionally, the hierarchical power consumption processing measures include first-level power consumption processing measures and second-level power consumption processing measures; wherein, the first-level power consumption processing measures are used to prompt the user to restart the four-wheel drive system according to a pre-configured prompt strategy through the vehicle's in-vehicle interactive system to end the abnormal power consumption state of the four-wheel drive controller; the second-level power consumption processing measures are used to automatically restart the four-wheel drive system to end the abnormal power consumption state of the four-wheel drive controller; the minimum timing time value of the timing interval corresponding to the second-level power consumption processing measures is greater than the maximum timing time value of the timing interval corresponding to the first-level power consumption processing measures. Optionally, the prompt strategy includes prompt content and / or prompt frequency.

[0072] Optionally, there are at least two first-level power consumption processing measures; when the prompt strategy includes prompt content, the prompt content of the first-level power consumption processing measures corresponding to the subsequent timing interval is higher in urgency than the first-level power consumption processing measures corresponding to the prior timing interval; when the prompt strategy includes prompt frequency, the prompt frequency of the first-level power consumption processing measures corresponding to the subsequent timing interval is higher than the first-level power consumption processing measures corresponding to the prior timing interval, and the minimum timing time value of the subsequent timing interval is greater than the maximum timing time value of the prior timing interval.

[0073] Optionally, the second-level hierarchical power consumption processing measure is specifically used to countdown to restart the four-wheel drive system, and prompt the countdown time through the in-vehicle interactive system.

[0074] Optionally, the timing module 320 is also used to: during the process of timing the duration, if the engine is started, stop monitoring the power consumption status of the four-wheel drive controller and the graded power consumption processing measures currently being executed, and reset the timing accumulation value of the duration.

[0075] In summary, the vehicle control device of this embodiment achieves precise identification and graded intervention for abnormal power consumption conditions by real-time monitoring of the engine status and the quiescent current of the four-wheel drive controller. When the engine is not started and the quiescent current exceeds a preset current threshold, the four-wheel drive controller is determined to have entered an abnormal power consumption state, and a timer for this abnormal power consumption state is initiated. Subsequently, graded interventions can be dynamically implemented based on the duration of the abnormal power consumption state. For example, within 2-3 hours, the user may be prompted to restart the vehicle via the instrument cluster. If no response is received, a periodic warning combining voice and text messages may be issued within 3-5 hours. Finally, a forced restart of the four-wheel drive controller is initiated after 5 hours or more of no response. This solution guides user intervention through a progressively enhanced prompting strategy, avoiding user frustration. Furthermore, this embodiment further accommodates user operations. When the user starts the engine or restarts the four-wheel drive system, the timer is intelligently reset, preventing erroneous timer accumulation and the inadvertent triggering of power consumption intervention measures. The entire solution can be implemented within the vehicle control unit program and can be deployed via cloud-based upgrade technology for existing vehicles without requiring hardware modifications.

[0076] It should be noted that, regarding the vehicle control device in the above embodiment, the specific manner in which each model performs operations has been described in detail in the embodiment of the method, and will not be elaborated here.

[0077] In addition, another embodiment of the present application provides a vehicle. Figure 4 4 is a schematic diagram of the structure of the vehicle, including a memory 401 and a processor 402. The memory 401 stores an executable program code 4011. The processor 402 is configured to call and execute the executable program code 4011 to perform the vehicle control method provided in the above embodiment. The corresponding steps include: When the engine of the vehicle is not started, the power consumption state of the four-wheel drive controller of the vehicle is monitored.

[0078] If the four-wheel drive controller enters an abnormal power consumption state, the duration of the four-wheel drive controller in the abnormal power consumption state is timed; wherein, the abnormal power consumption state refers to the power consumption state reached by the four-wheel drive controller when performing vehicle detection when the engine is not started.

[0079] According to the timing interval to which the duration belongs, corresponding graded power consumption processing measures are executed; wherein different timing intervals correspond to different graded power consumption processing measures, and the graded power consumption processing measures are used to intervene and end the abnormal power consumption state.

[0080] The vehicle in this embodiment monitors the engine status and the quiescent current of the four-wheel drive controller, enabling precise identification and graded intervention for abnormal power consumption. When the engine is not started and the quiescent current exceeds a preset threshold, the four-wheel drive controller is deemed to have entered an abnormal power consumption state, and a timer for this state is initiated. Subsequently, graded interventions are dynamically implemented based on the duration of the abnormal power consumption state. For example, within 2-3 hours, the user may be prompted to restart the vehicle via the instrument cluster. If no response is received, this may be escalated to a periodic warning with a combination of voice and text within 3-5 hours. Finally, a forced restart of the four-wheel drive controller is initiated after 5 hours or more of no response. This solution guides user intervention through a progressively enhanced prompting strategy, avoiding user frustration. Furthermore, it further accommodates user actions by intelligently resetting the timer when the user starts the engine or restarts the four-wheel drive system, preventing erroneous timing accumulation and the inadvertent execution of power consumption measures. This functionality can be implemented within the vehicle's control unit program. For existing vehicles, deployment can be achieved through a simple cloud-based update, requiring no hardware modifications.

[0081] This embodiment can divide the vehicle into functional modules based on the above-described method example. For example, each functional module can be mapped to a specific function, or two or more functions can be integrated into a single processing module. The integrated module can be implemented in hardware. It should be noted that the module division in this embodiment is illustrative and represents only one logical functional division. In actual implementation, other division methods may be used.

[0082] In the case of dividing the functional modules into corresponding modules, the vehicle may include a monitoring module, a timing module, an execution module, etc. It should be noted that all relevant contents of the various steps involved in the above method embodiment can be referred to the functional description of the corresponding functional modules and will not be repeated here.

[0083] It should be understood that the vehicle provided in this embodiment is configured to execute the aforementioned vehicle control method, and thus can achieve the same effects as the aforementioned implementation method. Specifically, the vehicle in this embodiment can monitor the power consumption of the four-wheel drive controller in real time when the vehicle engine is not started. When the quiescent current value exceeds a preset threshold (e.g., 0.03A), a timer function is triggered, and graded intervention measures are implemented based on the duration of the high power consumption. For example, if the duration is between 2 and 3 hours, a text prompt (e.g., "Abnormal power consumption of the four-wheel drive controller. Please try restarting the vehicle") is sent to the user via the instrument panel to encourage proactive intervention. If the duration extends to between 3 and 5 hours, a warning prompt is issued (e.g., "Please restart the vehicle as soon as possible"), intensifying the prompt intensity. If the duration exceeds 5 hours, the system automatically intervenes on behalf of the user, executing a countdown and forcibly restarting the four-wheel drive system to restore the quiescent current value of the four-wheel drive controller to a low power consumption level (below 0.02A). The entire solution uses a dynamically graded "prompt-warning-forced restart" logic, which not only respects the user's operating intentions but also ensures the system's automatic recovery capabilities. It can be adapted to existing vehicle models without hardware changes (which can be achieved through system upgrades of the vehicle computer), effectively reducing the risk of battery power outages.

[0084] In the case of an integrated unit, the vehicle may include a processing module and a storage module. The processing module may be used to control and manage the vehicle's movements, while the storage module may be used to support the vehicle's execution of program codes and data.

When the computer program code is executed on a computer, the computer executes the above-mentioned related method steps to implement a vehicle control method provided in the above embodiment, wherein the specific steps include: When the engine of the vehicle is not started, the power consumption state of the four-wheel drive controller of the vehicle is monitored.

[0087] If the four-wheel drive controller enters an abnormal power consumption state, the duration of the four-wheel drive controller in the abnormal power consumption state is timed; wherein, the abnormal power consumption state refers to the power consumption state reached by the four-wheel drive controller when performing vehicle detection when the engine is not started.
