Description

Technical Field

[0001] This application relates to the field of new energy vehicle technology, and more specifically, to a vehicle control method and related equipment. Background Technology

[0002] With the rapid development of new energy vehicles and intelligent connected vehicle technologies, the level of vehicle intelligence and humanization is constantly improving, and drivers' demands for in-vehicle comfort and convenience are also increasing. Especially in the "rest mode" scenario when the vehicle is stationary, users often hope to obtain a quiet, comfortable, and private resting environment inside the car; however, existing models may still keep some external and internal electrical equipment in working condition after entering rest mode, such as daytime running lights, automatic headlights, automatic wipers, backlights, and ambient lights. This not only causes power consumption but also brings light pollution and noise interference, affecting the user's resting experience.

[0003] In existing technologies, vehicle control in nap mode primarily focuses on the management of the powertrain and air conditioning systems. If users wish to turn off external lighting and wipers, they typically need to manually operate multiple switches or adjust function modes. This is not only cumbersome but also prone to accidental activation or omissions at night or in inclement weather, leading to problems such as light interference, noise disturbance, and energy waste. Even when the vehicle is in nap mode and the user desires a quiet environment, sensors may automatically activate lights or wipers upon detecting changes in light or rain signals, resulting in significant changes in indoor and outdoor lighting and increased noise. This negatively impacts the user's rest experience and compromises privacy and comfort. In short, existing technologies in vehicle nap mode suffer from numerous external device interference issues, high energy consumption, and a poor user experience. Summary of the Invention

This reduces manual operation steps, requiring only a single command from the user to trigger multiple shutdown and shielding operations. Compared to the traditional method of manually turning off multiple switches, this significantly improves operational convenience and intelligence. Once the stealth function is activated, it automatically shuts off the drive output of the external lighting and wiper systems and shields the automatic control signals triggered by environmental sensors. This effectively prevents the vehicle from automatically turning on lights or wipers due to changes in lighting or rain during the user's rest period, preventing light pollution and noise interference, creating a quiet and comfortable in-car rest environment, and reducing unnecessary energy consumption. By turning off the external lights, the possibility of the vehicle's interior being observed from the outside is reduced, protecting the user's privacy. When the user is resting in the vehicle, the external lighting system remains off, making the vehicle's appearance more concealed and avoiding external visual interference, thus enhancing privacy and security during rest mode. Furthermore, with the stealth function activated, it can automatically adjust the operating status of the internal lighting system based on environmental sensor data, balancing lighting comfort and energy consumption control, further optimizing the user's rest experience. In summary, the vehicle control method provided in this application enables one-click activation of the stealth function in rest mode, automatically controls the closing and adjustment of internal and external vehicle accessories, avoids light and noise interference, reduces energy consumption, and improves operational convenience, privacy, and rest comfort.

[0023] The technical solutions of this application will be described in detail below with reference to the accompanying drawings of the embodiments. It should be noted that the described embodiments are only a part of this application, and not all embodiments. In the following description, the "some embodiments" mentioned are only a subset of all possible embodiments, which may be the same or different subsets, and different embodiments can be combined with each other without conflict.

[0024] Figure 1 This is a schematic flowchart illustrating a vehicle control method provided in an embodiment of this application. For example, see [link to example]. Figure 1 The vehicle control method provided in this application embodiment may include the following steps 101 to 103: Step 101: When the target vehicle is in a rest mode, obtain a first user instruction to activate the stealth function of the target vehicle, and activate the stealth function according to the first user instruction. In some examples, the target vehicle is the motor vehicle to which the vehicle control method of this application embodiment is applied. It can be a new energy vehicle, such as a pure electric vehicle or a plug-in hybrid vehicle. It is equipped with hardware components such as an integrated cockpit controller (ICC), a body domain controller (BDCU), a central gateway (GW), environmental sensors, a central control display screen, and an in-vehicle voice system, which can support the operation of rest mode and stealth function. For example, a pure electric sedan of a certain brand is equipped with a 15.6-inch central control screen with touch and voice interaction functions and a body domain controller that supports multi-mode control, which is the target vehicle in the embodiment of this application. The nap mode is a preset operating mode of the target vehicle to meet the user's need for short rest. The user can trigger this mode through the central control screen, voice command, or physical button. When the target vehicle enters nap mode, it will automatically perform a series of adjustments adapted to the rest scenario, such as the seat automatically adjusting to a semi-reclining or flat position, the air conditioning system switching to low fan speed recirculation mode, the windows automatically closing (or remaining in their current state), and the in-vehicle entertainment system stopping playback. For example, when the user stops to rest during a long drive, they can click the "Nap Mode" icon on the central control screen, and the vehicle seat will automatically move back and recline to 30°, the air conditioning will be adjusted to 24°C and fan speed level 1 recirculation, and the vehicle will be in nap mode. The stealth function is an auxiliary feature designed to reduce interference from external devices and lower energy consumption when the target vehicle is in rest mode. Its core function is to automatically shut off the drive output of external accessories (such as external lighting and wiper systems) upon receiving a start command, block external accessory activation signals triggered by environmental sensors, and dynamically control the working status of internal accessories (such as the interior lighting system) based on environmental sensor data. For example, after the stealth function is activated, the daytime running lights and automatic wipers stop working; the light and rain sensors automatically turn off the interior ambient lights when strong light is detected, and turn on the reading lights for one minute before turning them off when weak light is detected. The first user command is the instruction issued by the user to the vehicle to activate the stealth function when the target vehicle is in rest mode.

[0025] For example, when the target vehicle is in nap mode, the integrated cockpit controller automatically detects the vehicle status and triggers interaction preparation: the central control display jumps to the nap mode exclusive interface, which prominently displays the "stealth function" virtual switch, while the in-vehicle voice system outputs a prompt tone through the speaker (such as "To reduce interference, you can turn on the stealth function") and remains in listening mode; if the user chooses touch interaction and clicks the virtual switch, the integrated cockpit controller immediately captures the operation signal and generates the first user command; if the user chooses voice interaction and speaks the preset voice command, the in-vehicle voice system collects the voice signal through the microphone, verifies and matches it through the voice recognition module, and sends the recognition result to the integrated cockpit controller, which then generates the first user command; after obtaining the first user command, the integrated cockpit controller immediately sends a stealth function enable signal to the body domain controller to activate the stealth function.

[0026] By implementing step 101, when the vehicle is in rest mode, the user's command to activate the stealth function is obtained, and the stealth function can be automatically activated according to the command, realizing intelligent switching of vehicle status. This avoids the tedious process of the user having to manually operate multiple light or wiper switches, allowing the vehicle to automatically enter a quiet state suitable for rest with a single command, thereby improving the convenience of operation and the level of vehicle intelligence.

[0027] Step 102, in response to the activation state of the stealth function, turn off the drive output to at least one external accessory of the target vehicle and block the first control signal triggered by the sensing data of the environmental sensor of the target vehicle, wherein the first control signal is used to control at least one external accessory to perform an activation operation, and the at least one external accessory may include at least one of an external lighting system and a wiper system. In some examples, the process of responding to the activation state of the stealth function refers to the mechanism by which the vehicle control system (mainly the body domain controller) recognizes the activation state and triggers subsequent preset operations after the stealth function of the target vehicle is successfully activated. The drive output of at least one external accessory refers to the power output or control signal output that drives the external accessory of the target vehicle. This is achieved by the body domain controller through drive circuits or pulse width modulation (PWM) signals. Turning off this drive output cuts off the power source or control signal of the external accessory, causing it to stop working; for example, when the circuit output driving the daytime running lights is disconnected, the daytime running lights stop illuminating; when the PWM signal driving the front wiper motor is terminated, the front wipers stop oscillating. Environmental sensors are sensing devices on the target vehicle used to collect information about the external environment. These may include rain sensors (RLS), which can be installed inside the windshield to simultaneously detect the light intensity and rainfall around the vehicle. Other sensors may include ultrasonic sensors, but the core component is the rain sensor. For example, a rain sensor in a certain vehicle model can detect the ambient light level (range 0-20000 lux) and raindrop impact frequency (corresponding to rainfall amount) in real time. Sensing data is the raw environmental information data collected by the environmental sensors, including but not limited to light intensity data (in lux) and rainfall data (quantified by raindrop impact frequency or density). The first control signal is an electrical signal generated based on the sensing data from the environmental sensors to control the activation of external accessories. It is generated directly by the vehicle domain controller or the environmental sensors. For example, when the light intensity collected by the rain sensor is below 1000 lux, a first control signal to turn on the low beam headlights is generated; when the collected rainfall data reaches a preset threshold (e.g., an impact frequency of 5 times / second), a first control signal to turn on the windshield wipers is generated. The external lighting system is a collection of light components used by the target vehicle for external illumination or warning, and may include daytime running lights, position lights, low beam headlights, high beam headlights, rear fog lights, etc. The windshield wiper system is a device used by the target vehicle to remove rainwater, dust, and other debris from the windshield, including front wipers, rear wipers (configured on some models), and corresponding drive motors and linkage mechanisms; the front wipers are mounted on the front windshield, and the rear wipers are mounted on the rear windshield, achieving the cleaning function through the swing arm movement driven by a motor.

[0028] For example, when the stealth function is activated, the vehicle domain controller first confirms the state through signal detection, and then performs two core operations. First, it disconnects the output of the drive circuit of the external accessories (such as the relay of the daytime running lights and the drive module of the wiper motor), for example, cutting off the power supply circuit of the low beam headlights to stop the illumination, and stopping the drive signal sent to the front wiper motor to stop it in the initial position. Second, it activates the signal shielding mechanism, that is, the vehicle domain controller no longer responds to the first control signal generated by the light and rain sensor based on the sensor data, such as ignoring the request to turn on the low beam headlights when the light is insufficient and the request to start the wipers when the rainfall is sufficient.

[0029] By implementing step 102, after the stealth function is activated, the drive output of the external lighting system and the wiper system is automatically turned off, and the automatic start signal triggered by the environmental sensor is blocked. This prevents the lights or wipers from automatically starting due to environmental factors such as changes in light or rain, effectively avoiding light pollution and noise interference, ensuring a quiet and comfortable environment for users to rest in the car, while reducing unnecessary power consumption and improving the vehicle's energy efficiency management level.

[0030] Step 103: In response to the activation state of the stealth function, control the operating state of at least one internal accessory of the target vehicle based on the sensing data of the environmental sensor, wherein the at least one internal accessory may include an internal lighting system. In some examples, the process of controlling the operating state of at least one internal accessory of a target vehicle based on sensing data from environmental sensors refers to the vehicle's body domain controller receiving environmental information data collected by the environmental sensors when the stealth function is activated, and dynamically adjusting the operating state of the internal accessories (such as turning them on, off, or adjusting brightness) based on this data. The core logic is to match the environmental data with the adaptation state of the internal accessories, thus meeting the actual needs of the user while avoiding unnecessary energy consumption. For example, if the environmental sensor is a light and rain sensor, and the light intensity data it collects is 500 lux (belonging to a low-light environment), the body domain controller controls the reading lights in the internal lighting system to turn on; when the light intensity data is 5000 lux (belonging to a high-light environment), the body domain controller controls the internal lighting system to remain off. Interior accessories are devices installed inside a target vehicle to enhance driving comfort or convenience. Their operation directly affects the in-vehicle environment. Besides interior lighting systems, they may include in-vehicle fragrance systems, seat massage devices, and in-vehicle air purifiers. The operating status of interior accessories is controlled by the vehicle domain controller through control drive circuits or communication commands. For example, the on / off state of an in-vehicle fragrance system can be controlled by electrical signals sent by the vehicle domain controller. For instance, a certain vehicle model may include front reading lights, door ambient lights, and seat ventilation devices. The reading lights and ambient lights belong to the interior lighting system, while the seat ventilation devices are considered other types of interior accessories. An interior lighting system is a type of interior accessory, a collection of devices used to provide lighting for the vehicle interior. It may include reading lights (front and rear reading lights), ambient lights (door interior ambient lights, center console ambient lights), instrument panel backlights, and center console screen backlights. Its core function is to provide interior lighting for users in low-light environments (such as facilitating the placement of items or operation of equipment), or to create a comfortable resting atmosphere through ambient lighting.

[0031] By implementing step 103, when the stealth function is activated, the working status of the interior lighting system can be intelligently controlled based on the perception data of the environmental sensors. The interior lighting can be automatically turned on when the light is dim and automatically turned off when the light is sufficient, realizing dynamic adjustment of the interior lighting. This ensures both the user's convenience and visual comfort before and after rest, while avoiding unnecessary energy consumption, further enhancing the user experience in the nap mode and the vehicle's intelligent energy-saving performance.

[0032] In summary, this application embodiment achieves automated control of the vehicle's external and internal accessories by obtaining the user's command to activate the stealth function during vehicle rest mode. This reduces manual operation steps for the user; the user only needs to issue a single command to trigger the system to perform multiple shutdown and shielding operations. Compared to the traditional method of manually turning off multiple switches, this improves operational convenience and intelligence. After the stealth function is activated, it can automatically turn off the drive output of the external lighting system and wiper system, and shield the automatic control signals triggered by environmental sensors. This effectively prevents the vehicle from automatically turning on lights or other functions due to changes in lighting or rain during the user's rest period. Windshield wipers prevent light pollution and noise interference, creating a quiet and comfortable in-car rest environment while reducing unnecessary energy consumption. By turning off external lights, the possibility of the vehicle's interior being observed from the outside can be reduced, protecting user privacy and security. When the user is resting in the car, the external lighting system remains off, making the vehicle's appearance more concealed and avoiding external visual interference, thus enhancing privacy and security during rest mode. When the concealment function is activated, the operating status of the internal lighting system can be automatically adjusted based on the perception data of environmental sensors, thereby balancing lighting comfort and energy consumption control, further optimizing the user's rest experience. In summary, the vehicle control method provided in this application embodiment, by realizing one-button activation of the concealment function in rest mode and automatically controlling the closing and adjustment of the vehicle's internal and external accessories, can avoid light and noise interference, reduce energy consumption, and improve operational convenience, privacy, and rest comfort.

[0033] In some embodiments, the aforementioned acquisition of the first user instruction to activate the stealth function of the target vehicle when the target vehicle is in a rest mode may include: displaying a virtual switch for the stealth function on the central control display screen of the target vehicle when the target vehicle is in a rest mode, and activating the vehicle's in-vehicle voice system; generating the first user instruction based on the in-vehicle voice system detecting a preset voice or in response to the user's operation on the virtual switch.

[0034] In some examples, the central control display screen is a touch-screen display device installed in the center of the target vehicle's cockpit for human-machine interaction. Integrated with the integrated cockpit controller, it displays vehicle function interfaces, receives user touch operations, and provides feedback. The central control display screen typically uses LCD technology, supporting high-definition resolution and multi-touch, and is the core interactive carrier for users to operate vehicle functions. The virtual switch for the stealth function is a graphical interactive element displayed on the central control display screen used to trigger the stealth function. It can be presented as a button icon with clear text labels (such as "One-click stealth" or "Activate stealth function") and visual feedback (such as color change and icon highlighting after clicking). Its display is controlled by the integrated cockpit controller and only appears when the target vehicle is in rest mode, facilitating quick user location and operation. For example, after the target vehicle enters rest mode, the central control display screen automatically jumps to the rest mode interface, where a blue circular button is displayed in the center at the bottom with the text "Activate stealth." This button is the virtual switch for the stealth function. An in-vehicle voice system is a built-in system in a vehicle that supports voice interaction. It consists of a microphone (for capturing user voice), a voice recognition module (for parsing voice content), a voice synthesis module (for outputting voice feedback), and a speaker (for playing feedback sound). Its core function is to convert user voice commands into control signals that the vehicle can execute. The in-vehicle voice system can be integrated into the cockpit controller and can be activated by a wake-up word (such as "Hello, Xiao X") or maintain continuous monitoring in specific modes. For example, a certain vehicle model's in-vehicle voice system supports commands such as "Activate stealth function" and "Turn off interior lights," allowing users to control vehicle functions via voice without manual operation. The process of generating the first user command based on the in-vehicle voice system detecting preset voice commands involves the in-vehicle voice system capturing specific voice content spoken by the user in monitoring mode. After recognizing and verifying the match with preset commands, it generates a control signal to activate the stealth function. For example, when a user is in nap mode and says "Activate stealth function" into the in-vehicle microphone, the in-vehicle voice system recognizes that the voice matches the preset command and then generates the first user command. The process of generating the first user command in response to the user's operation of the virtual switch is that after the integrated cockpit controller detects the user's touch operation on the stealth function virtual switch on the central control display, it generates a control signal to activate the stealth function; for example, when the user taps the "Activate Stealth" virtual button with their finger in the rest mode interface, the integrated cockpit controller detects the operation and immediately generates the first user command.

[0035] For example, when the target vehicle enters the nap mode, the integrated cockpit controller sends a display command to the central control display screen, causing the central control display screen to switch to the nap mode exclusive interface. This interface prominently displays a virtual switch with the text "One-click stealth". At the same time, the integrated cockpit controller sends an activation command to the in-vehicle voice system, causing it to enter a continuous listening state (responding to voice without a wake-up word). If the user chooses touch operation and taps the virtual switch with their finger, the touch module of the central control display screen transmits the operation signal to the integrated cockpit controller. After verification, the integrated cockpit controller generates the first user command. If the user chooses voice operation and says "Activate stealth function", the microphone of the in-vehicle voice system collects the voice signal. After the recognition module confirms that it matches the preset voice, it transmits the recognition result to the integrated cockpit controller. The integrated cockpit controller generates the first user command based on the result.

[0036] Through the implementation of the above embodiments, a virtual switch for the stealth function is displayed on the vehicle's central control screen. Combined with the vehicle's voice system to recognize user voice commands, the user's multimodal trigger control of the stealth function is realized. This allows the user to quickly activate the stealth function by voice or by lightly touching the screen when the vehicle is stationary, relaxed, or preparing to rest, without performing complex operations, thus improving the ease of operation and the level of intelligent interaction.

[0037] In some embodiments, the aforementioned shutting off the drive output to at least one external accessory of the target vehicle may include: controlling the drive circuit corresponding to at least one of the target vehicle's daytime running lights, position lights, low beam headlights, high beam headlights, and rear fog lights to disconnect; and / or controlling the drive circuit corresponding to at least one of the target vehicle's front and rear windshield wipers to disconnect.

[0038] In some examples, daytime running lights (DRLs), position lights, low beam headlights, high beam headlights, and rear fog lights are all core components of the target vehicle's external lighting system, used to provide illumination or indicate the vehicle's position in different environments. Specifically, DRLs are daytime lighting devices that automatically turn on after the vehicle starts, enhancing the vehicle's visibility during the day; position lights are contour lights that turn on in low-light environments, indicating the vehicle's width and length; low beam headlights are used for short-range illumination at night or on cloudy days, with a lower beam angle to avoid glare for oncoming vehicles; high beam headlights are used for long-distance illumination at night when there are no oncoming vehicles, with a higher beam angle and longer illumination distance; and rear fog lights are used in low-visibility environments such as fog, rain, and snow, installed at the rear of the vehicle, using strong penetrating light to alert vehicles behind. The drive circuit is a circuit module that provides operating power or control signals to external accessories. It can consist of components such as a power module, relays, switching transistors (such as MOSFETs), and protective resistors, and is integrated into the vehicle domain controller or a separate power control unit. Its core function is to receive control commands and turn on / off the power supply circuit for external accessories. The front and rear windshield wipers are the actuators of the windshield wiping system of the target vehicle, used to clear rainwater, dust, and other debris from the windshield to ensure the driver's visibility. The front wiper is mounted below the windshield and consists of a drive motor, a control arm, and a wiper blade, achieving cleaning through the reciprocating swing of the control arm. The rear wiper is mounted on the rear windshield, and its structure is similar to the front wiper, but it is usually smaller and has a lower swing frequency.

[0039] For example, when the stealth function is activated, the body domain controller first obtains a list of external accessories that need to be turned off (including at least one of the aforementioned headlights and / or wipers), and then sends a disconnect command to the corresponding drive circuit. For headlights, for example, when the daytime running lights and low beams need to be turned off, the body domain controller sends a disconnect signal to the relay of the daytime running light drive circuit, causing the relay contacts to separate and cutting off the 12V power supply circuit of the daytime running lights, thus turning off the daytime running lights. At the same time, it sends a disconnect signal with the same logic to the low beam drive circuit, and the low beams are then turned off. For wipers, for example, when the front wipers need to be turned off, the body domain controller stops outputting PWM signals to the front wiper drive circuit, the drive motor loses power, and the swing arm stops at the initial position. If the rear wipers are in operation, the signal output of their drive circuit is also cut off, causing them to stop operating.

[0040] By implementing the above embodiments, the drive circuits for controlling the vehicle's daytime running lights, position lights, low beam headlights, high beam headlights, rear fog lights, and front and rear wipers are disconnected. This enables the complete shutdown of the external lighting system and wiper system after the stealth function is activated, cutting off the energy consumption path at the source. This not only avoids interference from external light flickering and wiper noise to resting users, but also effectively reduces the load pressure on the battery storage system, extends the vehicle's range, and improves the energy efficiency of new energy vehicles in static mode.

[0041] In some embodiments, controlling the operating state of at least one internal accessory of the target vehicle based on the sensing data of the environmental sensor may include: acquiring the light intensity of the surrounding environment of the target vehicle collected by the environmental sensor; if the light intensity is greater than a preset intensity threshold, turning off the drive output of the internal lighting system; if the light intensity is less than or equal to the preset intensity threshold, turning on at least one lighting unit in the internal lighting system, and simultaneously recording the current start-up duration of at least one lighting unit; and turning off the drive output of the internal lighting system when the current start-up duration reaches a preset duration.

[0042] In some examples, illuminance refers to the intensity of light in the environment surrounding the target vehicle, measured in lux. Its core function is to reflect the brightness of the environment, providing a basis for controlling the internal lighting system. Illuminance can be acquired in real time by a light and rain sensor installed on the target vehicle. This sensor is typically installed below the rearview mirror inside the windshield. It senses changes in ambient light through photosensitive elements and converts them into quantified electrical signals, which are then transmitted to the body domain controller for data analysis. The preset intensity threshold is a critical value of illuminance pre-calibrated in the body domain controller to distinguish between bright and dark environments. Its value can be set according to the usage scenarios of different vehicle models (such as urban roads and suburban roads) and the user's rest needs, and can also be fine-tuned through vehicle system parameters. For example, automakers write a default threshold (such as 1000 lux) into the body domain controller during the vehicle production stage. Users can also adjust the threshold to 800 lux or 1200 lux through the "Nap Mode Settings" interface on the central control display to suit their personal habits. If the light intensity is greater than the preset intensity threshold, the process of turning off the drive output of the interior lighting system is as follows: After receiving the light intensity data transmitted by the light and rain sensor, the vehicle domain controller compares it with the preset intensity threshold. If the data is greater than the threshold (determined to be a bright environment), it sends a "disconnect signal" to the drive circuit of the interior lighting system to cut off the power supply or control signal of the lighting unit, so that the interior lighting system stops working immediately, in order to avoid light pollution (affecting users' rest) and power consumption caused by turning on the interior lighting in a bright environment (new energy vehicles rely on battery power, and redundant power consumption will shorten the range). If the light intensity is less than or equal to a preset intensity threshold, the process of activating at least one lighting unit in the interior lighting system involves the vehicle domain controller sending a "conduction signal" to the drive circuit of at least one lighting unit in the interior lighting system when the light intensity data is lower than or equal to the preset intensity threshold (determined as a dim environment). This powers the unit on to meet the user's basic lighting needs in dim environments (such as placing a mobile phone or adjusting the seat angle). The selection of at least one lighting unit can be preset by the system, prioritizing units with high usage frequency and concentrated lighting range (such as front reading lights). Alternatively, it can be adjusted by the user to a combination of "front reading lights + center console ambient lights." A lighting unit is a single lighting component in the interior lighting system that can be independently controlled to turn on or off. These include front reading lights, rear reading lights, door ambient lights, center console ambient lights, instrument panel backlights, and center screen backlights. Each lighting unit has an independent drive circuit, controlled individually by the vehicle domain controller. The current startup duration is the cumulative running time from the startup time to the current time after the internal lighting unit is turned on. This data can be recorded and obtained in real time by the timer built into the vehicle domain controller. For example, if the front reading lights are turned on at 14:00:00, the current startup duration at 14:00:30 is 30 seconds, and the current startup duration at 14:01:00 is 60 seconds.The preset duration is the maximum duration for which the lighting unit is continuously turned on, calibrated in the vehicle domain controller. Its value setting needs to balance user needs (such as time to tidy up items) and energy consumption control. The default setting is 60 seconds (1 minute), and users can adjust it to 30 seconds, 90 seconds, etc. through the "Nap Mode Settings" interface on the central control display. The preset duration can be obtained in the same way as the preset intensity threshold, which is "factory calibration + user adjustment". For example, the default preset duration of the car manufacturer is 60 seconds, and users can adjust it to 90 seconds according to their own habits to allow more lighting time. When the current startup duration reaches the preset duration, the process of shutting off the drive output of the interior lighting system involves the vehicle domain controller comparing the current startup duration with the preset duration in real time. When the two are equal (i.e., the lighting unit has been continuously on for the preset duration), it immediately sends a "disconnect signal" to the drive circuit of the interior lighting system, cutting off the power supply to the lighting unit and stopping it from working. This ensures that the interior lighting is turned off promptly after meeting the user's basic lighting needs, reducing power consumption and avoiding energy waste caused by the lighting unit being on for a long time. For example, if the preset duration is set to 60 seconds, when the current startup duration reaches 60 seconds, the vehicle domain controller sends a disconnect signal to the drive circuit of the front reading light, which immediately turns off. At the same time, the timer is reset to zero, waiting to restart the timer when the lighting unit is turned on next time.

[0043] For example, when the stealth function is activated, the vehicle domain controller first receives real-time light intensity data (e.g., a detected value of 800 lux) transmitted by the light and rain sensor through the central gateway, and compares it with a preset intensity threshold (e.g., 1000 lux). Since 800 lux is less than 1000 lux, the vehicle domain controller sends a conduction signal to the drive circuit of the front reading light, causing the reading light to light up. At the same time, it starts a built-in timer to record the current activation duration. The timer updates the data in real time in seconds. When the current activation duration accumulates to the preset duration (e.g., 60 seconds), the vehicle domain controller determines that the lighting requirement has been met and immediately sends a disconnect signal to the reading light drive circuit, turning off the reading light. If the detected light intensity value is 2000 lux (greater than the preset threshold of 1000 lux), the vehicle domain controller directly sends a disconnect signal to the drive circuit of all internal lighting units to ensure that the internal lighting system is turned off throughout, thus avoiding light pollution and reducing the battery energy consumption of new energy vehicles.

[0044] By implementing the above embodiments, the light intensity detected by the environmental sensor is obtained, and the start and stop status of the internal lighting system is automatically controlled according to different lighting conditions to realize intelligent adjustment of the in-vehicle light environment. When the external light is strong, the lighting is automatically turned off to avoid energy waste; when the light is insufficient, the lighting is automatically turned on and turned off for a limited time to facilitate short-term use by users. It can optimize energy consumption distribution while ensuring rest comfort, making the in-vehicle environment softer and more humane.

[0045] In some embodiments, the aforementioned vehicle control method may further include: obtaining the target duration of the nap mode; determining a preset duration based on the light intensity and the target duration, wherein the preset duration is negatively correlated with the light intensity and positively correlated with the target duration.

[0046] In some examples, the target duration is the expected duration of the vehicle's nap mode, usually measured in minutes. Its core function is to reflect the user's planned rest duration and provide a basis for the dynamic adjustment of the preset duration of the interior lighting system. The target duration can be obtained through user-initiated settings and intelligent system prediction. On the one hand, users can manually input the duration (e.g., 30 minutes) through the nap mode setting interface on the central control display, or send a voice command (e.g., "take a 20-minute nap") through the in-vehicle voice system. Alternatively, it can be automatically generated based on the user's historical nap data (e.g., the average duration of the user's past 5 naps is 25 minutes) and current driving time (e.g., after driving continuously for 2 hours, it is predicted that the user needs to rest for 30 minutes). The process of determining the preset duration based on light intensity and target maintenance duration involves the vehicle domain controller using a preset algorithm, combined with light intensity data collected by light and rain sensors and the target maintenance duration, to calculate the continuous on-time (i.e., preset duration) of the internal lighting unit. The preset duration is negatively correlated with light intensity; that is, the weaker the ambient light (the lower the light intensity value), the longer the preset duration. For example, at night when light intensity is low, users need longer lighting time to organize items. The preset duration is positively correlated with the target maintenance duration; that is, the longer the user's planned nap, the longer the preset duration. For example, a user planning a 1-hour rest requires a longer initial lighting time than a 10-minute rest. The specific determination method can be implemented using a formula, such as: Preset Duration = (Base Duration + Target Maintenance Duration × Coefficient A) × (Base Light Intensity ÷ Current Light Intensity), where the base duration is 10 seconds, the coefficient A is 0.5, and the base light intensity is 1000 lux. Alternatively, it can be implemented using a preset mapping table, where the system has built-in preset durations corresponding to different combinations of light intensity and target maintenance duration, which can be directly matched and called.

[0047] For example, when the target vehicle enters rest mode and the stealth function is activated, the integrated cockpit controller first obtains the user-set target duration (e.g., 20 minutes) through the central control display or the in-vehicle voice system, and transmits this data to the body domain controller through the central gateway. At the same time, the body domain controller receives the real-time light intensity (e.g., 300 lux) collected by the light and rain sensors, and calculates it using a preset algorithm: if the base duration is 10 seconds, the coefficient A is 0.5, and the reference light intensity is 1000 lux, then the preset duration = (10 + 20 × 0.5) × (1000 ÷ 300) = (10 + 10) × 3.33 ≈ 66.6 seconds, rounded to 67 seconds. Subsequently, the body domain controller controls the on-time of the internal lighting units (e.g., front reading lights) according to the preset duration, which not only meets the user's lighting needs in dim environments, but also adapts to their rest duration to reduce unnecessary energy consumption.

[0048] By implementing the above embodiments, a target maintenance duration parameter is introduced into the stealth mode. The lighting duration of the internal lighting system can be dynamically determined according to the ambient light intensity and the preset rest duration. This makes the lighting control more in line with the user's rest cycle and environmental changes. The negative correlation between light intensity and preset duration realizes a flexible adjustment mechanism of short-term bright light and long-term dim light, which helps to achieve a comfortable and energy-saving lighting strategy in different environments and further improves the vehicle's energy-saving performance.

[0049] In some embodiments, the aforementioned acquisition of the target duration of the nap mode may include: acquiring user image data through the vehicle-mounted camera of the target vehicle; identifying the user identity and current action of the target user based on the user image data; acquiring a baseline duration matching the user identity; matching the current action with a standard action node to determine the current completion level of the target user's nap; and determining the target duration based on the current completion level and the baseline duration.

[0050] In some examples, the in-vehicle camera is a high-definition image acquisition device pre-installed inside the target vehicle to collect image information of the in-vehicle user. It can be integrated below the rearview mirror or above the center console and has the capabilities of real-time shooting, dynamic frame capture, and low-light environment imaging. Its core function is to provide an image data source for user identification and action analysis. User image data is a collection of image information collected in real time by the in-vehicle camera, including the target user's facial information, body movements, and the in-vehicle environment. It covers static images (such as close-ups of the face) and dynamic image sequences (such as continuous action frames). The acquisition method is that the in-vehicle camera automatically starts shooting after the target vehicle enters the nap mode. The data is transmitted in real time to the image processing module of the integrated cockpit controller through the image transmission line. For example, when the user is about to activate the nap mode, the in-vehicle camera continuously captures 10 frames of images, of which 3 frames are images of the user's face and 7 frames are images of the user's action sequence of adjusting the seat. These images together constitute the user image data. The target user is the person currently triggering and using the nap mode in the target vehicle, typically the driver (since nap mode is mostly used in the driver's seat), but may also include the front passenger (some models support multi-seat nap mode). User identity is the specific identifier of the target user, clearly identifying them as a specific user registered in the vehicle system (e.g., "User Zhang San," "Family Account 1"), rather than an anonymous individual. Specifically, this can be achieved by the integrated cockpit controller performing facial recognition on the user's face image captured by the in-vehicle camera, matching the recognition result with the user account information stored in the vehicle system (e.g., facial feature database, account name). If a match is successful, the user's identity is confirmed. For example, if the in-vehicle camera captures a facial image of the target user, the integrated cockpit controller extracts facial features using a facial recognition algorithm, compares it with the pre-stored facial features of "User Li Si" in the system, and if the similarity is above 95%, the user's identity is determined to be "User Li Si." The current action refers to the real-time physical behavior of the target user within the target vehicle that is related to the nap mode, including but not limited to "adjusting the seat back angle," "lowering the headrest," "fastening the seatbelt," "placing the phone," and "lying down." This is acquired by the vehicle's camera capturing real-time dynamic frames of the target user's limbs. The action recognition module integrated into the cockpit controller extracts features and analyzes the behavior of these dynamic frames to determine the current action type. For example, if the vehicle's camera continuously captures the target user operating the seat adjustment buttons with both hands and reclining the seat back from 90° to 45°, the action recognition module determines the current action as "adjusting the seat back to a semi-reclined position." The baseline maintenance duration is the average duration of the user's historical nap mode usage, which is linked to the target user's identity and reflects the user's regular nap habits. This data is stored in the vehicle's user behavior database. For example, the historical average nap duration for "User Li Si" is 23 minutes, and the corresponding baseline maintenance duration is 23 minutes.Standard action nodes are a sequence of typical action steps that a user experiences when completing a full nap, preset by the target vehicle system. This sequence covers key behavioral nodes from "preparing for a nap" to "ending a nap," and may include nodes such as triggering nap mode, adjusting the seat, lowering the headrest, lying down, entering a resting state, getting up, and turning off nap mode. Each node corresponds to a specific action characteristic and completion percentage, such as "adjusting the seat" corresponding to a completion percentage of 10%, "lying down" corresponding to a completion percentage of 30%, and "placing the phone in the armrest box" corresponding to a completion percentage of 40%. The current completion rate is the percentage of the rest process progress corresponding to the target user's current action compared with the standard action node. It is used to reflect the progress of the user's actions before entering a "stable rest state". It can be achieved by integrating the cockpit controller to match the identified current action with the standard action node one by one, determine the node position to which the current action belongs, and then calculate the current completion rate based on the completion rate percentage corresponding to that node. For example, if the target user's current action is "adjust the seat back to a semi-reclined position", it matches the "adjust seat" node in the standard action nodes. This node corresponds to a completion rate of 30%, so the current completion rate is determined to be 30%. The process of determining the target duration of a nap based on the current completion rate and the baseline duration involves the integrated cockpit controller using a preset algorithm. This algorithm combines the current completion rate (reflecting the progress of the nap preparation) with the baseline duration (reflecting the user's regular rest needs) to calculate the remaining duration of the current nap mode for the target user. This duration will serve as the basis for subsequent control of the preset duration of the internal lighting system and the shutdown duration of external accessories. For example, the preset algorithm is: Target duration = Baseline duration × (1 - Current completion rate / 100). If the baseline duration of "User Li Si" is 23 minutes and the current completion rate is 30%, then the target duration = 23 × (1 - 30 / 100) = 16.1 minutes (the system can automatically round it to 16 minutes). If the current completion rate is 50%, then the target duration = 23 × (1 - 50 / 100) = 11.5 minutes.

[0051] By implementing the above embodiments, user image data is acquired using an in-vehicle camera, user identity and current actions are identified, and the target duration of the nap is calculated based on this. This enables personalized identification and dynamic adjustment of the rest state, allowing the vehicle to intelligently determine the rest duration according to different user habits and actual conditions, thereby automatically matching the duration of the stealth function, reducing user intervention, and improving the active perception and adaptive control capabilities of new energy vehicles in the field of intelligent cockpits.

[0052] In some embodiments, the aforementioned activation of the stealth function according to the first user instruction may include: in response to the first user instruction, acquiring environmental state data of the target vehicle, wherein the environmental state data may include the light intensity, noise level, and moving object density of the environment surrounding the target vehicle; based on the environmental state data, evaluating whether to activate the stealth function and obtaining an evaluation score; if the evaluation score is greater than or equal to a preset score threshold, controlling the activation of the stealth function; if the evaluation score is less than the preset score threshold, outputting a warning message prompting the activation of the stealth function; and in response to a user confirmation instruction to the warning message, controlling the activation of the stealth function.

[0053] In some examples, environmental state data is a comprehensive set of environmental information used to assess whether the environment around the target vehicle is suitable for activating the stealth function. Its core function is to provide an objective basis for the decision to activate the stealth function, ensuring the necessity and rationality of activating the function. The environmental state data is acquired by the target vehicle through the collaborative collection of multiple on-board sensors. Light intensity can be collected by a light and rain sensor, noise level can be collected by an in-vehicle noise sensor, and moving object density can be collected by an ultrasonic sensor or a surround view camera. All data is aggregated by a central gateway and transmitted to the integrated cockpit controller. For example, the environmental state data collected in a certain scenario is: light intensity 800 lux, noise level 65 dB, and moving object density 0.8 objects / square meter (i.e., an average of 0.8 moving objects per square meter). Light intensity, noise level, and moving object density are core parameters of environmental status data. Light intensity is the strength of ambient light (in lux), reflecting the potential interference of external lighting on users' rest (e.g., strong light can attract prying eyes from passersby). Noise level is the loudness of ambient sound (in decibels), reflecting the degree of impact of external noise on rest (e.g., in a high-decibel environment, the additional interference from windshield wiper noise is relatively small). Moving object density is the number of moving objects (e.g., pedestrians, vehicles) per unit area (in units per square meter), reflecting the density of surrounding human activity (at high density, stealth features are more important for privacy protection). The evaluation score is a quantified value (typically ranging from 0 to 100 points) based on environmental condition data to assess the "necessity of activating stealth capabilities." A higher score indicates a more urgent need to activate stealth capabilities. The score is obtained by the integrated cockpit controller using a preset algorithm to weight light intensity, noise level, and moving object density. For example, moving object density has a weight of 40% (higher density, higher score), light intensity has a weight of 30% (higher intensity, higher score), and noise level has a weight of 30% (lower intensity, higher score). Each parameter is converted into a single score according to a preset mapping table, and then the weighted sum is obtained to obtain the evaluation score. For example, a moving object density of 1.2 objects / square meter corresponds to a single score of 90 points, a light intensity of 500 lux corresponds to a single score of 60 points, and a noise level of 70 decibels corresponds to a single score of 30 points. The evaluation score is 90 × 40% + 60 × 30% + 30 × 30% = 36 + 18 + 9 = 63 points.The preset score threshold is a critical score value used to determine whether to automatically activate the stealth function. It can be preset according to the user's rest scenario needs (e.g., 80 points), and the user can adjust it through the "Function Settings" interface on the central control display (e.g., to 70 or 90 points). Its core function is to distinguish between scenarios that "can be activated without user confirmation" and those that "require user confirmation to activate." When the evaluation score is higher than or equal to the threshold, the activation requirement is clear, and activation is executed automatically; when it is lower than the threshold, the requirement is considered pending confirmation, and the user needs to be prompted. For example, the default preset score threshold is 80 points. When the evaluation score is 85 points, the stealth function is automatically activated; when the evaluation score is 63 points, a warning message is triggered. The warning message prompting the user to activate the stealth function is a prompt displayed to the user when the evaluation score is lower than the preset score threshold, reminding the user whether to activate the stealth function, aiming to balance the autonomy of the function and the user's right to choose. The user confirmation command for the warning message is an operation signal sent by the user to the vehicle after receiving the warning message, agreeing to activate the stealth function. This authorizes the system to still execute the activation action even if the evaluation score is insufficient. It can be obtained in two ways: first, through touch interaction, where the user clicks the "Confirm" button on the warning message on the central control display, and the touch signal is transmitted to the integrated cockpit controller; second, through voice interaction, where the user speaks a preset confirmation voice (such as "Activate" or "Confirm") to the in-vehicle voice system, and the voice signal is recognized and transmitted to the integrated cockpit controller. For example, after hearing the voice prompt, the user clicks the "Confirm" button on the central control screen, and the generated signal is the user confirmation command for the warning message.

[0054] By implementing the above embodiments, the vehicle's surrounding environment status data (including light intensity, noise level, and density of moving objects) is acquired and comprehensively evaluated. This enables intelligent judgment and adaptive triggering of the stealth function. When the vehicle's surrounding environment is noisy, brightly lit, or has people moving around, the stealth function is proactively prompted or automatically activated, improving the accuracy and safety of judging resting scenarios. Its decision-making mechanism based on multi-dimensional environmental perception enables the vehicle to have higher scene recognition and active control capabilities, enhancing the human-machine collaborative experience of new energy vehicles.

[0055] In some embodiments, the aforementioned target vehicle may include an integrated cockpit controller, a central gateway, and a body domain controller; the aforementioned activation of the stealth function according to the first user instruction may include: the integrated cockpit controller generating a target enable signal in response to the first user instruction and forwarding the target enable signal to the body domain controller through the central gateway; the body domain controller activating the stealth function in response to the target enable signal; the aforementioned deactivation of drive output to at least one external accessory of the target vehicle and shielding of the first control signal triggered by sensing data from the target vehicle's environmental sensors in response to the activation state of the stealth function may include: the body domain controller deactivating drive output to at least one external accessory of the target vehicle and shielding the first control signal triggered by sensing data from the target vehicle's environmental sensors in response to the activation state of the stealth function; step 103 may include: the body domain controller controlling the operating state of at least one internal accessory of the target vehicle based on sensing data from the environmental sensors in response to the activation state of the stealth function.

[0056] In some examples, the integrated cockpit controller is the core control unit in the target vehicle responsible for handling human-machine interaction within the cockpit and integrating cockpit domain functions. It integrates functions such as central control display control, in-vehicle voice system management, and user command parsing, serving as the central hub for user-vehicle functional interaction. The integrated cockpit controller can communicate with other controllers via in-vehicle Ethernet or Controller Area Network (CAN). The central gateway is the communication hub in the target vehicle responsible for data interaction and protocol conversion between various domain controllers. Its core function is to realize signal forwarding between different networks (such as CAN, LIN, and in-vehicle Ethernet), ensuring smooth transmission of commands and data between different domain units such as the integrated cockpit controller and the body domain controller. The body domain controller is the core unit in the target vehicle responsible for managing the control logic of body accessories (such as lights, wipers, and interior lighting). It directly connects to the drive circuits of external and internal accessories, receiving control commands and executing specific switching and adjustment operations. The target enable signal is an electrical signal or data frame generated by the integrated cockpit controller after receiving the first user command. It is used to instruct the body domain controller to activate the stealth function. Its signal format follows the controller area network protocol, such as CAN signal, with the identifier 0x1A5 and a data length of 8 bytes. The first byte is the "enable flag bit", and 0x01 indicates that it is enabled. The generation of the target enable signal is completed by the instruction processing module of the integrated cockpit controller. For example, when the user clicks the "activate stealth" virtual switch, the integrated cockpit controller immediately generates a CAN data frame containing the "stealth function activated" instruction as the target enable signal. The process by which the integrated cockpit controller, in response to a first user command, generates a target enable signal and forwards it to the body domain controller via the central gateway, involves the integrated cockpit controller initiating a signal generation and forwarding process after recognizing the first user command (such as a user-touch virtual switch or voice command). First, the integrated cockpit controller's command parsing module verifies the validity of the first user command. Then, it generates a target enable signal containing the command "Enable stealth function." Finally, it sends this signal to the central gateway via the vehicle Ethernet. The central gateway converts the signal protocol (e.g., from Ethernet frame to CAN frame) and forwards it to the receiving port of the body domain controller. The process by which the body domain controller, in response to the target enable signal, activates the stealth function involves the body domain controller parsing and verifying the signal after receiving it. After confirming the signal's validity (e.g., checking the signal format and enable flag), it activates the internal "stealth function control module," putting the stealth function into the active state (i.e., switching from "off" to "on").In response to the activation of the stealth function, the vehicle domain controller shuts down the drive output to at least one external accessory of the target vehicle and shields the first control signal triggered by the sensing data from the target vehicle's environmental sensors. This process involves the vehicle domain controller performing two core operations after confirming the stealth function is activated: first, disconnecting the output by controlling the drive circuits of the external accessories (such as relays or MOSFETs); and second, implementing a signal shielding mechanism, ignoring the first control signal generated by the environmental sensors (such as light and rain sensors) based on their sensing data, such as the low beam headlight activation request in low light or the wiper activation request in rain. For example, when the light and rain sensor sends a CAN signal to "turn on low beam headlights," the vehicle domain controller's signal filtering module directly discards the signal without performing any operation. The vehicle domain controller also controls the operating state of at least one internal accessory of the target vehicle based on the sensing data from the environmental sensors in response to the stealth function's activation. This process involves the vehicle domain controller receiving real-time sensing data (such as light intensity) from the environmental sensors (such as light and rain sensors) and adjusting the operating state (on / off, duration) of the internal accessories (such as the interior lighting system) according to the data after the stealth function is activated.

[0057] By implementing the above embodiments, the distributed collaborative control of stealth functions can be achieved by utilizing the signal linkage between the integrated cockpit controller, the central gateway, and the body domain controller. This ensures high-speed and reliable transmission of user commands between different control domains, making the triggering and execution of stealth functions synchronous and stable. At the same time, each controller has a clear division of labor and can independently complete the shutdown of external accessories and the adjustment of internal lighting, thus constructing an efficient inter-domain collaborative control architecture and improving the response speed and control accuracy of the method.

[0058] In some embodiments, the aforementioned vehicle control method may further include: the body domain controller generating a first status signal in response to the activation state of the stealth function, and forwarding the first status signal from the central gateway to the integrated cockpit controller, so that the integrated cockpit controller outputs the first status information of the stealth function based on the central control display and / or the in-vehicle voice system; in response to the activation state of the stealth function, obtaining a second user instruction to disable the stealth function; the integrated cockpit controller generating a target enable / disable signal in response to the second user instruction, and forwarding the target enable / disable signal from the central gateway to the body domain controller, so that the body domain controller disables the stealth function; responding to the disable state of the stealth function through the body domain controller, and generating a second status signal; forwarding the second status signal from the central gateway to the integrated cockpit controller through the body domain controller, so that the integrated cockpit controller outputs the second status information of the stealth function based on the central control display and / or the in-vehicle voice system.

[0059] In some examples, the first status signal is generated by the vehicle domain controller after confirming that the stealth function has entered the activated state. It serves to provide feedback on the current status of the function and its core function is to synchronize the information that the stealth function has been activated to the integrated cockpit controller. The first status information is output by the integrated cockpit controller to the user based on the first status signal, indicating that the stealth function has been activated. This information can take the form of text / icon display on the central control screen and voice announcement from the in-vehicle voice system, aiming to clearly inform the user of the function's status. The content of the first status information can be preset, for example, the text message could be "Stealth function activated, exterior lights and wipers turned off," and the voice message could be "Stealth function activated, will reduce external interference for you." After confirming the stealth function is activated, the vehicle domain controller immediately triggers the first state signal generation process, generating a CAN data frame containing the "activated" flag. This signal is then sent to the central gateway via the controller area network. The central gateway converts the signal protocol (e.g., from CAN frame to vehicle Ethernet frame) before forwarding it to the integrated cockpit controller. The integrated cockpit controller parses the signal, controls the central control display to show the text and icons of the first state information, and drives the in-vehicle voice system to broadcast the corresponding voice message through the speakers, thus informing the user. The second user command is a command issued by the user to the vehicle to deactivate the stealth function when it is activated. Its function is the opposite of the first user command, used to terminate the stealth function. The second user command is obtained in the same way as the first user command, including touch interaction (clicking the "Deactivate Stealth" virtual switch on the central control display) and voice interaction (speaking preset voice messages to the in-vehicle voice system, such as "Deactivate Stealth Function" or "Exit Stealth Mode"). The process of obtaining a second user command to disable the stealth function in response to its activation state involves the following steps: When the stealth function is activated, the integrated cockpit controller continuously monitors user interactions, displays a virtual "Disable Stealth" switch (mutually exclusive to the "On" switch) on the central control screen, and keeps the in-vehicle voice system active (supporting direct response to disabling commands). When the user triggers the disabling request via touch of the virtual switch or voice command, the integrated cockpit controller captures and parses the operation, generating a second user command. Upon receiving the second user command, the integrated cockpit controller generates a target enable / disable signal to indicate the disabling of the stealth function. This signal is sent to the central gateway via the in-vehicle Ethernet, and the central gateway forwards it to the body domain controller after protocol conversion. After parsing the signal, the body domain controller terminates the operation of the stealth function control module, switches its internal state to "Disable," and restores the normal control logic of external accessories (such as deactivating the drive circuit and canceling the first control signal shielding). The second status signal is generated by the body domain controller after confirming that the stealth function has entered the disabled state, serving as feedback on the current status of the function. Its function is to synchronize the information that the stealth function is disabled with the integrated cockpit controller.The second status information is a message output by the integrated cockpit controller to the user based on the second status signal, indicating that the stealth function has been disabled. This message can be displayed as text / icons on the central control screen or read aloud via the vehicle's voice system. The content can be preset, for example, the text message could be "Stealth function disabled, external devices are back to normal," and the voice message could be "Stealth function deactivated, all functions have returned to default settings." After confirming that the stealth function is disabled, the body domain controller generates a second status signal containing a "disabled" flag. This signal is then sent to the central gateway via the controller area network. The central gateway converts the protocol and forwards the signal to the integrated cockpit controller. After parsing the signal, the integrated cockpit controller controls the central control screen to display the text and icons of the second status information and drives the vehicle's voice system to read the corresponding message, thus informing the user.

[0060] By implementing the above embodiments, the real-time status display and voice prompts of the stealth function are realized through the status signal feedback between the vehicle domain controller and the integrated cockpit controller, enhancing the user's perception and controllability of the function's execution status. When the stealth function is turned on or off, the status information is output through the central control screen or voice system, allowing the user to understand the vehicle status immediately and avoid the trouble caused by misoperation or unclear status. At the same time, this closed-loop feedback mechanism improves the human-computer interaction experience and safety reliability of the method, making the stealth function more practical in new energy vehicles.
