Description

Technical Field

[0001] This application relates to the field of automotive technology, specifically to vehicle control technology, data processing technology, and other technical fields, and particularly to a method, device, equipment, and storage medium for displaying vehicle start-up prompt information. Background Technology

[0002] New energy vehicles, especially battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), rely heavily on their core power source—the battery. The performance of these batteries is significantly sensitive to temperature. In low-temperature environments (typically below 0°C), the viscosity of the electrolyte inside the battery increases, the lithium-ion migration rate decreases, and the activity of the electrode materials reduces, leading to a sharp increase in internal resistance and a significant decrease in usable capacity and discharge power. Furthermore, the physical characteristics of basic vehicle components such as tires are also affected by low temperatures, resulting in the recurring problem of false alarms.

[0003] However, the current human-machine interaction system of new energy vehicles, especially the instrument cluster which is the core of human-machine interaction, has obvious deficiencies in the display strategy of battery and tire pressure warning information in the special winter scenario. Summary of the Invention

[0004] This application provides a method, device, equipment, and storage medium for displaying vehicle start-up prompt information, which can solve the problem of poor interactivity in the display of start-up prompt information for new energy vehicles. The technical solution is as follows: Firstly, a method for displaying vehicle start-up prompt information is provided, the method comprising: Acquire battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration; Based on the battery pack temperature, battery heating status signal, ambient temperature, and vehicle static duration, a preset battery preheating evaluation strategy is used to determine the battery preheating prompt information and low-temperature start display mode. Based on the battery preheating prompt information and the low temperature start-up display mode, a pop-up window displaying the battery preheating prompt information is generated; Based on the ambient temperature and tire pressure information, tire pressure warning information is obtained using a preset tire pressure assessment strategy. Based on the tire pressure warning information and the low temperature start display mode, a tire pressure warning information display interface is generated; Based on the display pop-up window for the battery preheating prompt and the display interface for the tire pressure prompt, the battery preheating prompt and the tire pressure prompt are displayed respectively.

[0005] In one possible implementation, acquiring the battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration includes: In response to the driver's start operation, a vehicle start signal is obtained; Based on the vehicle start signal, the battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration are obtained.

[0006] In one possible implementation, the step of determining battery preheating prompt information and low-temperature start-up display mode based on the battery pack temperature, battery heating status signal, ambient temperature, and vehicle static duration, using a preset battery preheating evaluation strategy, includes: If the battery pack temperature is less than a first temperature threshold, the ambient temperature is less than a second temperature threshold, the vehicle static duration is greater than a first duration threshold, and the battery heating status signal is on, the vehicle starting scenario is determined to be a low-temperature starting scenario. Based on the aforementioned low-temperature startup scenario, the low-temperature startup display mode is triggered. Based on the battery pack temperature, ambient temperature, and a first temperature threshold, a battery preheating prompt message is determined.

[0007] In one possible implementation, the battery preheating prompt information includes ambient temperature, preheating temperature progress, preheating time progress, and prompt text. Based on the battery preheating prompt information and the low-temperature start-up display mode, a display pop-up window for the battery preheating prompt information is generated, including: The display pop-up window is determined based on the aforementioned low-temperature startup display mode; Based on the ambient temperature, an ambient temperature icon is generated in the first display area of ​​the pop-up window; Based on the preheating temperature progress, a preheating temperature progress bar is generated in the second display area of ​​the display pop-up window; Based on the preheating time progress, a preheating time progress bar is generated in the third display area of ​​the display pop-up window; Based on the prompt text, the preheating prompt message is generated in the fourth display area of ​​the pop-up window.

[0008] In one possible implementation, the tire pressure information includes tire pressure value and tire condition information. The step of obtaining tire pressure warning information based on the ambient temperature and tire pressure information using a preset tire pressure assessment strategy includes: When the ambient temperature is less than the second temperature threshold, determine whether the tire pressure value is greater than the first pressure threshold and less than the second pressure threshold, and whether the tire status information is normal. When the tire pressure value is greater than the first pressure threshold and less than the second pressure threshold, and the tire status information is normal, a tire pressure warning message is obtained.

[0009] In one possible implementation, the method further includes: The temperature of the first individual cell is determined based on the battery pack temperature. In response to the first single cell temperature being greater than or equal to the first temperature threshold and the battery preheating status signal being off, the display pop-up is closed and the low-temperature start-up display mode is exited.

[0010] Secondly, a vehicle start-up notification information display device is provided, the device comprising: The first acquisition unit is used to acquire battery pack temperature, battery heating status signal, ambient temperature, tire pressure information and vehicle static duration; The first determining unit is used to determine the battery preheating prompt information and low temperature start display mode based on the battery pack temperature, battery heating status signal, ambient temperature and vehicle static duration, using a preset battery preheating evaluation strategy. The first generation unit is used to generate a display pop-up window for the battery preheating prompt information based on the battery preheating prompt information and the low temperature start-up display mode; The first obtaining unit is used to obtain tire pressure warning information based on the ambient temperature and tire pressure information and using a preset tire pressure assessment strategy. The second generation unit is used to generate a display interface for the tire pressure warning information based on the tire pressure warning information and the low temperature start display mode; The first display unit is used to display the battery preheating reminder information and the tire pressure reminder information respectively through a display pop-up window based on the battery preheating reminder information and a display interface based on the tire pressure reminder information.

[0011] Thirdly, a computer-readable storage medium is provided, wherein at least one instruction is stored therein, the at least one instruction being loaded and executed by a processor to implement the aspects and any possible implementations described above.

[0012] Fourthly, an electronic device is provided, comprising: At least one processor; and A memory communicatively connected to the at least one processor; wherein, The memory stores instructions that can be executed by the at least one processor to enable the at least one processor to perform the methods described above and any possible implementations.

[0013] Fifthly, a new energy commercial vehicle is provided, including the electronic equipment described in the above-mentioned aspects.

[0014] The beneficial effects of the technical solution provided in this application include at least the following: As can be seen from the above technical solution, the embodiments of this application can obtain battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration. Based on the battery pack temperature, battery heating status signal, ambient temperature, and vehicle static duration, a preset battery preheating evaluation strategy can be used to determine battery preheating prompt information and a low-temperature start display mode. Based on the battery preheating prompt information and the low-temperature start display mode, a display pop-up window for battery preheating prompt information is generated. Based on the ambient temperature and tire pressure information, a preset tire pressure evaluation strategy is used to obtain tire pressure prompt information. Based on the tire pressure prompt information and the low-temperature start display mode... The system generates a display interface for tire pressure warning information. Based on the display pop-up window for battery preheating warning information and the display interface for tire pressure warning information, the system displays the battery preheating warning information and tire pressure warning information respectively. By displaying the battery preheating warning information and tire pressure warning information, the invisible background process is transformed into visible and quantifiable information, allowing users to have a clear expectation of the vehicle's readiness status. This solves the problem of frequent false alarms in the early morning of winter, significantly reduces driver anxiety while waiting in the cold, improves the friendliness of the cabin environment, and provides drivers with more effective interactive information in the scenario of starting the vehicle in winter, thereby optimizing the driver's driving experience.

[0015] It should be understood that the description in this section is not intended to identify key or essential features of the embodiments of this application, nor is it intended to limit the scope of this application. Other features of this application will become readily apparent from the following description. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Detailed Implementation

[0018] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of this application, including various details to aid understanding. These should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of this application. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0019] Obviously, the described embodiments are only some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0020] Furthermore, the term "and / or" in this article 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 existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0021] Currently, on the one hand, most vehicles treat the battery management system's heating function as a purely background engineering task, neglecting the fact that the vehicle's battery preheating process is a front-end service that affects the driver's operating rhythm and psychological expectations. This lack of human-machine interaction and prompts fails to provide a good user driving experience. On the other hand, during vehicle startup, tire pressure alarm schemes often employ a single threshold and a mechanical alarm strategy without contextual judgment. They only perceive the isolated parameter of pressure, failing to integrate key contextual information such as ambient temperature and vehicle status (stationary / moving). This results in inaccurate and unintelligent outputs in low-temperature winter conditions. Moreover, battery preheating and tire pressure alarms are two independently operating subsystems, each sending signals to the instrument cluster through its own logic. The instrument cluster typically only passively receives and simply reproduces these signals, unable to integrate and intelligently display the received signals.

[0022] Therefore, in winter, when starting a vehicle, the driver may simultaneously encounter: an incomprehensible battery heating icon, a constantly flashing tire pressure warning light, and potentially limited power response due to insufficient battery temperature. These isolated and even contradictory pieces of information create a chaotic and confusing cockpit interaction environment, thereby reducing the driver's driving experience.

[0023] Therefore, there is an urgent need for a method to display vehicle start-up prompts that can provide drivers with more effective interactive information in winter vehicle start-up scenarios, thereby optimizing the driver's driving experience.

[0024] Please refer to Figure 1 This document illustrates a flowchart of a method for displaying vehicle start-up notification information according to an embodiment of this application. This method, applied to a combination instrument cluster or cockpit domain controller, may specifically include: Step 101: Obtain battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration.

[0025] Step 102: Based on the battery pack temperature, battery heating status signal, ambient temperature and vehicle static duration, determine the battery preheating prompt information and low temperature start display mode using a preset battery preheating evaluation strategy.

[0026] Step 103: Based on the battery preheating prompt information and the low temperature start-up display mode, generate a pop-up window displaying the battery preheating prompt information.

[0027] Step 104: Based on the ambient temperature and tire pressure information, obtain tire pressure warning information using a preset tire pressure assessment strategy.

[0028] Step 105: Based on the tire pressure warning information and the low temperature start display mode, generate a display interface for the tire pressure warning information.

[0029] Step 106: Based on the display pop-up window for the battery preheating reminder information and the display interface for the tire pressure reminder information, display the battery preheating reminder information and the tire pressure reminder information respectively.

[0030] It should be noted that the battery pack temperature can be obtained from the Battery Management System (BMS). Upon vehicle startup, the BMS immediately wakes up and detects the battery pack, measuring the lowest individual cell temperature to determine the overall battery pack temperature. The BMS can periodically send data frames containing signals such as battery pack temperature and battery heating status signals via the controller area network. The battery heating status signal indicates that preheating has been activated.

[0031] It should be noted that the ambient temperature can be the temperature outside the vehicle. This ambient temperature can be obtained through an ambient temperature sensor. The ambient temperature sensor can measure the outside temperature and transmit it via the CAN bus.

[0032] It should be noted that tire pressure information can be obtained through a Tire Pressure Monitoring System (TPMS). The TPMS obtains tire pressure values ​​through pressure sensors in four tires: left front, right front, left rear, and right rear. A tire pressure value above its internal absolute danger threshold of 180 kPa, used to detect rapid leaks, indicates that the tire pressure is normal. The TPMS can send tire status information including the pressure values ​​of each tire, as well as tire status information where the "rapid tire pressure loss" or "severe low pressure" fault flag is not set.

[0033] It should be noted that the vehicle's static duration can be obtained through the body control system. The body control system can send signals such as ignition status and vehicle static duration.

[0034] Understandably, the instrument cluster, or the cockpit domain controller, can continuously monitor signal messages on the aforementioned bus.

[0035] It should be noted that the instrument cluster may include a display screen, a main control unit (MCU), non-volatile memory (NVM), instrument underlying software, and application layer software (HMI). The main control unit of the instrument cluster can continuously monitor the signal messages on the aforementioned buses.

[0036] In this way, by acquiring battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration, a battery preheating prompt message and a low-temperature start display mode can be determined using a preset battery preheating assessment strategy. Based on the battery pack temperature, battery heating status signal, ambient temperature, and vehicle static duration, a battery preheating prompt message pop-up is generated. Similarly, based on the ambient temperature and tire pressure information, a tire pressure prompt message is obtained using a preset tire pressure assessment strategy. Finally, a tire pressure prompt message is generated based on the tire pressure prompt message and the low-temperature start display mode. The display interface for the prompt information, based on the pop-up window for battery preheating prompt information and the display interface for tire pressure prompt information, displays the battery preheating prompt information and tire pressure prompt information respectively. By displaying the battery preheating prompt information and tire pressure prompt information, the invisible background process is transformed into visible and quantifiable information, allowing users to have a clear expectation of the vehicle's readiness status. This solves the problem of frequent false alarms in the early morning of winter, significantly reduces the driver's anxiety while waiting in the cold, improves the friendliness of the cabin environment, and enables more effective interactive information to be provided to the driver in the scenario of starting the vehicle in winter, thereby optimizing the driver's driving experience.

[0037] Optionally, in one possible implementation of this embodiment, in step 101, firstly, a vehicle start signal can be obtained in response to the driver's start operation on the vehicle. Secondly, based on the vehicle start signal, battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration can be obtained.

[0038] In this implementation, the vehicle start signal can be the vehicle ignition status signal.

[0039] In one specific implementation of this method, in response to the driver's start operation of the vehicle, the vehicle ignition status signal can be obtained from the body controller, which is "on".

[0040] In this implementation, the driver's starting operation of the vehicle may include pressing the brake pedal or pressing the start button.

[0041] In this implementation, the battery heating status signal can be a battery preheating status signal. Here, the battery preheating status signal can be "preheating enabled".

[0042] In this way, when the driver starts the vehicle, the current battery pack temperature, battery heating status signal, ambient temperature, tire pressure information, and vehicle static duration can be obtained in a timely manner based on the vehicle start signal, so that relevant vehicle start information can be quickly generated subsequently.

[0043] Optionally, in one possible implementation of this embodiment, in step 102, firstly, the vehicle's starting scenario can be determined to be a low-temperature starting scenario if the battery pack temperature is lower than a first temperature threshold, the ambient temperature is lower than a second temperature threshold, the vehicle's static duration is greater than a first duration threshold, and the battery heating status signal is on. Secondly, a low-temperature starting display mode can be triggered based on the low-temperature starting scenario. Thirdly, battery preheating prompt information can be determined based on the battery pack temperature, ambient temperature, and the first temperature threshold.

[0044] In this implementation, the first temperature threshold can be determined based on the lower limit of the battery's optimal operating temperature. Preferably, the first temperature threshold can be 10°C.

[0045] In this implementation, the second temperature threshold can be determined based on the freezing point temperature. Preferably, the second temperature threshold can be 0°C.

[0046] In this implementation, the first duration threshold can be determined based on the actual temperature of the vehicle's operating environment. Preferably, the first duration threshold can be 1 hour.

[0047] In a specific implementation of this method, firstly, the temperatures of the first and second individual cells can be determined based on the battery pack temperature. Secondly, the preheating temperature progress of the battery can be calculated based on the temperatures of the first and second individual cells and a first temperature threshold.

[0048] Here, the temperature of the first individual cell can be the lowest temperature of the individual cell. The temperature of the second individual cell can be the current temperature of the individual cell.

[0049] For example, the preheating temperature progress of the battery can be calculated based on the temperature of the first single cell, the temperature of the second single cell, and the first temperature threshold, as shown in formula (1): T=(T_cell_current - T_cell_min) / (T_optimal - T_cell_min) (1) Where T can be the preheating temperature progress, T_cell_current can be the temperature of the second cell, T_cell_min can be the temperature of the first cell, and T_optimal can be the first temperature threshold.

[0050] In another specific implementation of this approach, firstly, the remaining battery heating time of the vehicle can be obtained. Secondly, based on the remaining battery heating time, the battery preheating time schedule can be obtained.

[0051] Here, the remaining battery heating time can be obtained from the BMS.

[0052] Understandably, the BMS can calculate the initial estimated time required for the battery to heat up by 15°C based on the current average cell temperature, target heating temperature, heater power, and battery pack thermal model; that is, the initial remaining battery heating time. Furthermore, the BMS dynamically adjusts the remaining time every second based on the actual temperature rise rate (e.g., 0.2°C / s), providing the adjusted remaining battery heating time, and broadcasts this adjusted remaining time on the CAN bus.

[0053] In another specific implementation of this method, the ambient temperature is determined to be the ambient temperature in the battery preheating prompt information.

[0054] In this way, after determining that the low-temperature start-up display mode has been triggered, accurate and effective battery preheating prompt information can be determined based on the battery pack temperature, ambient temperature, and a first temperature threshold.

[0055] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to implement the vehicle start prompt information display method of this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.

[0056] Optionally, in one possible implementation of this embodiment, the battery preheating prompt information may include ambient temperature, preheating temperature progress, and preheating time progress. In step 103, firstly, the display pop-up window can be determined based on the low-temperature start display mode. Secondly, an ambient temperature icon can be generated in the first display area of ​​the display pop-up window based on the ambient temperature. Thirdly, a preheating temperature progress bar can be generated in the second display area of ​​the display pop-up window based on the preheating temperature progress. Fourthly, a preheating time progress bar can be generated in the third display area of ​​the display pop-up window based on the preheating time progress. Finally, the preheating prompt message can be generated in the fourth display area of ​​the display pop-up window based on the prompt text.

[0057] In this implementation, the pop-up window can be displayed on the instrument cluster's screen. The first display area can be the top area of ​​the pop-up window.

[0058] In one specific implementation of this method, based on the ambient temperature, an ambient temperature icon and text information corresponding to the ambient temperature are generated in the top area of ​​the display pop-up window.

[0059] For example, a snowflake icon and the number "-15℃" could be displayed in the top area to inform users of the frigid external environment.

[0060] In this implementation, the second display area can be the central area of ​​the pop-up window.

[0061] In another specific implementation of this method, based on the preheating temperature progress, a preheating temperature progress bar and corresponding text information are generated in the central area of ​​the display pop-up window. The preheating temperature progress bar can be dynamic.

[0062] For example, the left side of the central area could feature a dynamic battery icon progress bar with an animation of filling upwards from the bottom, the fill ratio determined by the preheating temperature progress. The right side of the central area could display the current battery temperature in large font: "-8℃", with "Preheating" indicated in smaller font below.

[0063] In this implementation, the third display area can be the bottom area of ​​the pop-up window.

[0064] In another specific implementation of this method, a preheating time progress bar and corresponding text information are generated in the bottom area of ​​the display pop-up window based on the preheating time progress. The filling speed of the preheating time progress bar is determined based on the preheating time progress.

[0065] For example, a preheating time progress bar is generated at the bottom of the pop-up window, gradually filling from left to right, with the filling rate synchronized with the preheating time progress. A clear countdown text is displayed below the progress bar: "Estimated wait: 11 minutes and 30 seconds." This number updates once per second.

[0066] In another specific implementation of this approach, a prompt message can be displayed in a smaller font below or to the side of the pop-up card: "Battery is warming up for optimal range and power, please wait.", as an auxiliary prompt.

[0067] In this way, by dynamically displaying the remaining battery warm-up time, the invisible background process can be transformed into visible and quantifiable information, allowing users to have a clear expectation of the vehicle's readiness status, thereby significantly reducing confusion and anxiety in severe cold weather and optimizing the user experience in the cockpit.

[0068] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to implement the vehicle start prompt information display method of this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.

[0069] Optionally, in one possible implementation of this embodiment, the tire pressure information may include tire pressure value and tire status information. In step 104, firstly, if the ambient temperature is less than a second temperature threshold, it can be determined whether the tire pressure value is greater than a first pressure threshold and less than a second pressure threshold, and whether the tire status information is normal. Secondly, if the tire pressure value is greater than the first pressure threshold and less than the second pressure threshold, and the tire status information is normal, tire pressure warning information can be obtained.

[0070] In this implementation, the first pressure threshold can be a preset protective pressure value. The second pressure threshold can be the standard cold tire pressure value.

[0071] Here, the preset protection pressure value can be obtained by querying a mapping table between preset protection pressure thresholds and ambient temperature. For example, at -15℃, the preset protection pressure value can be 210 kPa.

[0072] In this implementation, the tire status information indicating a normal status can be represented by a fault indicator indicating no rapid air leakage.

[0073] In this implementation, the tire pressure warning information may include suppressing the standard tire pressure alarm and enabling the low temperature warning mode.

[0074] In a specific implementation of this method, in step 106, the display interface for tire pressure warning information may include a virtual tire icon and the corresponding pressure value, as well as warning text, and the virtual tire icon and the corresponding pressure value are displayed according to a preset color.

[0075] Here, in the cold start display mode, the virtual tire icon and corresponding pressure value can be displayed in a soft color such as amber or blue to indicate that the vehicle is in cold start display mode. The prompt text can be something like, "Ambient temperature is low, tire pressure has temporarily dropped. It will rise again after driving a short distance."

[0076] In this way, the system can intelligently distinguish between tire pressure drops caused by low temperatures and real air leaks under other conditions, solving the problem of frequent false tire pressure alarms in the early mornings of winter and improving the cabin environment's user-friendliness.

[0077] It should be noted that the specific implementation process provided in this embodiment can be combined with various specific implementation processes provided in the foregoing implementation methods to implement the vehicle start prompt information display method of this embodiment. Detailed descriptions can be found in the relevant content of the foregoing implementation methods, and will not be repeated here.

[0078] Optionally, in one possible implementation of this embodiment, after step 106, the temperature of the first individual cell can be determined based on the battery pack temperature. Then, in response to the first individual cell temperature being greater than or equal to a first temperature threshold and the battery preheating status signal being off, the display pop-up can be closed and the low-temperature startup display mode can be exited.

[0079] In one specific implementation of this method, when the temperature of the first single cell is greater than or equal to the first temperature threshold, and the battery preheating status signal is off and no remaining preheating time is obtained, the display pop-up is closed and the low temperature start-up display mode is exited.

[0080] For example, after approximately 12 minutes of preheating, the lowest individual cell temperature is determined to reach 11°C, exceeding the first temperature threshold of 10°C. The instrument cluster detects this change and immediately closes the central "Battery Preheating Status Card" pop-up. The instrument cluster interface smoothly transitions to the normal "READY" or driving status interface. Simultaneously, a brief, positive audio prompt may be played, along with a momentary pop-up message: "Battery preheating complete, ready to go." In another specific implementation of this method, in response to the tire pressure value being greater than a preset proportion of a second pressure threshold and the ambient temperature being less than a second temperature threshold, the tire icon and tire pressure value are displayed and output in normal mode through the tire pressure warning information display interface.

[0081] Here, the preset ratio can be 98%.

[0082] For example, the user engages a gear and drives. After approximately 10 minutes, the tires generate heat due to rolling friction, and the temperature rises. The TPMS reports updated pressure values: all four tires at 245 kPa. When the instrument cluster detects that all tire pressure values ​​of 245 kPa are within the tolerance range of the standard pressure value of 250 kPa (e.g., reaching more than 98% of the standard value) and the ambient temperature is below a second temperature threshold, the tire pressure warning display can be updated: the color of all tire pressure values ​​automatically changes from amber to green. The explanatory text at the bottom automatically disappears.

[0083] Understandably, the entire process here is completed silently without any user intervention, clearly conveying the message that "the status has returned to normal".

[0084] In another specific implementation of this method, in response to the tire pressure value being less than the first pressure threshold and the tire status information indicating a slow tire pressure loss fault, the low temperature start display mode is exited, and a tire pressure fault alarm message is output.

[0085] For example, when the tire pressure of the left front tire is detected to drop below a preset protection pressure value, the instrument cluster exits the cold start display mode. The yellow tire pressure warning light on the instrument panel illuminates, possibly accompanied by a warning sound. Furthermore, on the tire pressure warning information display screen, the value for the left front tire flashes red, and a warning icon may be added. A warning message pops up: "Left front tire pressure continues to drop; please check immediately." Understandably, the intelligent suppression of tire pressure warnings here is temporary and conditional. Once a tire experiences a real malfunction not caused by low temperature, the instrument cluster will immediately resume the highest level of warning to ensure vehicle safety.

[0086] This allows users to simultaneously display outdoor temperature, battery temperature, and tire status information, providing a holistic and interconnected understanding of the situation—"severe cold environment—battery needs heating—falsely low tire pressure"—with a user-friendly interactive logic. It breaks down information silos between the BMS, TPMS, and instrument cluster systems, creating a collaborative judgment and display logic specifically designed for winter cold starts.

[0087] Furthermore, clear preheating prompts effectively guide users to wait for the battery to reach its optimal operating temperature before driving, avoiding potential damage to battery life caused by forced high-power discharge at low temperatures. By suppressing meaningless false alarms, the system protects the authority of safety warning signals such as tire pressure monitoring. When a real air leak occurs, the system can immediately escalate the alarm, ensuring that critical safety information is not habitually ignored by users and eliminating safety hazards caused by alarm fatigue.
