[0050] Figure 8 This is a schematic diagram of the structure of a vehicle provided in an embodiment of this application. Detailed Implementation

[0051] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text 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, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0052] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0053] Figure 1 This is a schematic diagram of the architecture of a sound source prompting system provided in an embodiment of this application.

[0054] For example, please see Figure 1 The sound source alert system may include a vehicle 100, which may include multiple devices 110 of the same type and sound source alert devices 120 corresponding to the locations of the multiple devices 110. The multiple devices 110 are located at different positions within the vehicle 100. The devices 110 and the sound source alert devices 120 are communicatively connected via signal lines 130. In some embodiments, the devices 110 and the sound source alert devices 120 may also be communicatively connected via wireless signals such as a network or Bluetooth. The specific configuration can be determined according to actual needs, and this application does not impose any limitations.

[0055] Specifically, multiple devices 110 of the same type can be the left and right front doors and left and right rear doors belonging to the door type; or the left and right front door windows, left and right rear door windows and sunroof belonging to the window type; or the left turn signal and right turn signal belonging to the turn signal type indicating vehicle turning; or the front left seat belt, front right seat belt, rear left seat belt and rear right seat belt belonging to the seat belt type; or the left front wheel tire, right front wheel tire, left rear wheel tire and right rear wheel tire belonging to the wheel tire type, etc.

[0056] The sound source indication device 120 is typically a speaker inside the vehicle (but can also be other sound-producing devices). There are usually four or eight speakers in the passenger compartment. The arrangement of multiple speakers can improve the stereo effect of the sound played by the audio-visual equipment in the passenger compartment, thereby providing the driver (or passenger) with a surround immersive auditory experience.

[0057] Taking a vehicle with eight speakers as an example, the speakers are typically installed in the following locations: one speaker on each of the left and right sides between the dashboard and the windshield, one speaker on each of the left and right front doors, one speaker on each of the left and right rear doors, and one speaker on each of the left and right C-pillars. It should be noted that the number and installation locations of speakers vary depending on the vehicle model and should be described according to the specific circumstances; this application does not impose any limitations.

[0058] Furthermore, the left front door, left front door window, and left turn signal can correspond to the speaker located on the left front door; the right front door, right front door window, and right turn signal can correspond to the speaker located on the right front door; the left rear door and left rear door window can correspond to the speaker located on the left rear door; and the right rear door and right rear door window can correspond to the speaker located on the right rear door.

[0059] When the device is in a preset state (such as an open door, open window, or turn signal on), the vehicle can use the in-vehicle infotainment system to control the speaker corresponding to the device's location to emit a warning sound. The driver (or passenger) can directly determine the location of the device in the preset state based on the source of the warning sound, saving time searching for it. This also provides the driver (or passenger) with certainty about the device's location, reducing anxiety associated with searching for such a device.

[0060] For example, when the vehicle's engine is turned off and the driver (or passenger) is about to leave the vehicle, if the left front door is not closed, a speaker located on the left front door will sound an alarm. The driver (or passenger) can directly know the location of the unclosed door based on the location of the alarm, saving the driver (or passenger) time in searching for the unclosed door; at the same time, it also gives the driver (or passenger) certainty about the location of the unclosed door, thereby reducing the anxiety caused by the driver (or passenger) searching for the unclosed door.

[0061] In some embodiments, the left front door, left front door window, and left turn signal may correspond to a speaker located on the left side between the dashboard and the windshield; the right front door, right front door window, and right turn signal may correspond to a speaker located on the right side between the dashboard and the windshield; the left rear door and left rear door window may correspond to a speaker located on the left C-pillar; and the right rear door and right rear door window may correspond to a speaker located on the right C-pillar. Specific configurations can be made according to actual needs, and this application does not impose specific limitations.

[0062] In some embodiments, a corresponding speaker can be installed at the location of each vehicle door, each window, each turn signal, and each seat belt. When the current state of the device is a preset state (such as an open door, an open window, or a turn signal on), the vehicle can control the speaker corresponding to the device's location to emit a warning sound via the vehicle's infotainment system; this can further improve the accuracy of the driver (or passenger) in locating the device in the preset state.

[0063] Figure 2 This is a schematic flowchart of a sound source prompting method provided in an embodiment of this application.

[0064] For example, please see Figure 2 Sound source cues can include:

[0065] S202, the vehicle obtains the current state of each of the multiple devices, and for each device, determines whether the current state of the device is a preset state.

[0066] Optionally, if the aforementioned device is a vehicle window, then the default state can be that the vehicle window is not closed.

[0067] Optionally, if the aforementioned device is a car door, then the default state can be that the car door is not closed.

[0068] Optionally, the aforementioned device can be a seat belt, in which case the default state can be that the seat belt is not being worn properly.

[0069] Optionally, if the device is a tire, the preset state can be that the tire pressure is less than a first preset threshold.

[0070] Optionally, if the above-mentioned device is a turn signal, then the default state is that the turn signal is on.

[0071] Furthermore, the vehicle's infotainment system detects the current state of each of the multiple devices and determines whether the current state of each device is a preset state.

[0072] For example, the aforementioned device may be a turn signal (including a left turn signal and a right turn signal), and the preset state may be that the turn signal is on. Specifically, a car typically includes four wheels: a left front wheel, a right front wheel, a left rear wheel, and a right rear wheel. When the car turns right, the left front wheel and the right front wheel are grouped together and turn to the right; when the car turns left, the left rear wheel and the right rear wheel are grouped together and turn to the right.

[0073] When the driver (or passenger) wants to turn left, they need to turn on the left turn signal. At this time, the left turn signal is in the preset state, that is, when the driver (or passenger) wants to turn left, they turn on the left turn signal and the left turn signal will illuminate.

[0074] When the driver (or passenger) wants to turn right, they need to turn on the right turn signal; at this time, the right turn signal is in the preset state, that is, when the driver (or passenger) wants to turn right, they turn on the right turn signal and the right turn signal will illuminate.

[0075] S204, the sound source prompting device corresponding to the position of the vehicle control and the first device emits a prompting sound, and the first device is the device whose current state is a preset state among multiple devices.

[0076] For example, taking the left turn signal of a car as the first device, where the first device is a turn signal light that illuminates in the car. When the left turn signal is detected to be illuminated, the speaker corresponding to the left turn signal emits a warning sound. It should be noted that the speaker corresponding to the left turn signal can be installed inside the left front door, and when the left turn signal is detected to be illuminated, the speaker located inside the left front door emits a warning sound. In some embodiments, taking the left front door as the first device, the preset state is that the door is not closed. When the vehicle's infotainment system determines that the vehicle door is not closed, the vehicle's infotainment system controls the speaker corresponding to the door position to emit a warning sound.

[0077] Specifically, after the vehicle's engine starts, or after the vehicle detects that the driver (or passenger) has exited the passenger compartment, the vehicle's infotainment system detects that the left front door is not closed (or not closed properly). At this time, the speaker located on the left front door emits a warning sound. The driver (or passenger) can directly know from the source of the warning sound that the left front door is not closed, saving the driver (or passenger) time in searching for the location of the unclosed door. At the same time, it also gives the driver (or passenger) certainty about the location of the unclosed door, thereby reducing the anxiety caused by the driver (or passenger) searching for the unclosed door.

[0078] During the execution of the embodiments of this application, when the vehicle detects that the current state of the device is a preset state, the vehicle can control the sound source prompting device corresponding to the device's location via the vehicle's infotainment system to emit a prompt sound. The driver (or passenger) can directly know the location of the device in the preset state based on the location source of the prompt sound, saving the driver (or passenger) time in searching for the device in the preset state; at the same time, it can also give the driver (or passenger) certainty about the location of the device in the preset state, thereby reducing the anxiety caused by the driver (or passenger) searching for the location of the device in the preset state.

[0079] Figure 3 This is a first schematic flowchart of a sound source prompting method provided in an embodiment of this application.

[0080] Please see Figure 3 The device is a seat belt, and the default state is that the seat belt is not being worn properly. The vehicle also includes a seat corresponding to each seat belt. For example, such as... Figure 3 As shown, sound source prompting methods may include:

[0081] S302, the vehicle obtains its current driving speed and determines whether the current driving speed is greater than a preset threshold.

[0082] Specifically, taking a car as an example, the car's speed sensor can detect the car's current speed in real time. When the car starts, the engine rotates, and the wheels rotate to give the car a starting speed. When converting the car's starting speed to the engine speed, the tire diameter needs to be considered. Each car model has a different tire diameter, meaning that even if the engine speed is the same when starting, different car models will have different starting speeds. However, the tire diameters of most car models are similar. Typically, when a car starts, the engine speed is 1200-1500 rpm, and the car's starting speed is usually around 9.6 km / h.

[0083] It should be noted that the vehicle model and the environmental factors in which the vehicle is located will affect the vehicle's starting speed, and this needs to be explained according to the actual situation. This application does not make any specific limitations.

[0084] With a preset threshold of 9.6 km / h for vehicle speed, when the vehicle's speed sensor detects that the current speed is greater than 9.6 km / h, it can be determined that the vehicle's current speed has reached the starting speed.

[0085] 304, the vehicle determines whether each seat is occupied.

[0086] When the car's current speed reaches the starting speed, the speed sensor triggers the seat pressure switch to detect whether anyone is sitting in each seat inside the car. S306, if the current driving speed is greater than a preset threshold, the vehicle control system, corresponding to the location of the second device, issues a warning sound.

[0087] Specifically, the second device is the first device that corresponds to the seat occupied by a person in the first device.

[0088] For example, each seat in a car is equipped with an SBR (Safety Belt Reminder), which includes at least a seat belt trigger switch, a seat pressure switch, a speaker circuit, and a power supply.

[0089] The power supply is connected to the car's speed sensor, which is connected in series with the seat belt trigger switch and the seat pressure switch. The seat belt trigger switch and the seat pressure switch are connected to the speakers corresponding to the seats.

[0090] For example, taking a car with four seats (including the front left seat, the front right seat, the rear left seat, and the rear right seat) as an example, when the car's speed sensor detects that the car's speed reaches 9.6 km / h, the speed sensor triggers the seat pressure switch to detect whether anyone is sitting in any of the car seats; further, based on the determination that someone is sitting in the car seat, the speed sensor triggers the seat belt trigger switch to detect whether the seat belt is properly worn.

[0091] It should be noted that the first device can be understood as any seat in a car where the seatbelt is not being worn properly; the second device can be understood as any seat in which someone is sitting where the seatbelt is not being worn properly.

[0092] Each seat is equipped with a seatbelt reminder device. When the car's speed sensor detects that the vehicle's speed reaches 9.6 km / h, the seatbelt reminder device corresponding to the seat occupied and not wearing a seatbelt will sound an alarm.

[0093] For example, taking the front left seat as an example, when it is detected that someone is sitting in the front left seat and the seat belt is not properly worn, the speaker corresponding to the front left seat will emit a warning sound. It should be noted that the speaker corresponding to the front left seat is usually installed at the bottom of the seat, and when it is detected that someone is sitting in the front left seat and the seat belt is not properly worn, the warning sound from the speaker corresponding to the front left seat will be emitted from the bottom of the front left seat.

[0094] When the embodiments of this application are executed, if it is detected that someone is sitting in the front left seat and the seat belt is not properly worn, the speaker located at the bottom of the front left seat will emit a warning sound. The driver (or passenger) can directly know from the source of the warning sound that the front left seat is not properly worn, saving the driver (or passenger) time to find the seat where the seat belt is not properly worn. At the same time, it can also give the driver (or passenger) certainty about the location of the seat where the seat belt is not properly worn, thereby reducing the anxiety caused by the driver (or passenger) searching for the location of the seat where the seat belt is not properly worn.

[0095] Figure 4 This is a second schematic flowchart of a sound source prompting method provided in an embodiment of this application.

[0096] Please see Figure 4 The device can be a tire, and the preset state can be that the tire pressure is less than a first preset threshold. For example, such as... Figure 4 As shown, sound source prompting methods may include:

[0097] S402, after detecting that the vehicle's engine has started, the vehicle acquires the current state of each of the plurality of devices at a preset time interval, and for each device, determines whether the current state of the device is a preset state.

[0098] For example, a vehicle can determine that its engine has started by detecting the movement of a pointer on its dashboard or by detecting continuous vibration of the vehicle body. In some embodiments, other methods can also be used to detect engine starting; this application is not limited to these methods and can be set according to actual conditions.

[0099] Once the car detects that the engine has started, the vehicle uses the TPMS (Tire Pressure Monitoring System) to automatically monitor the tire pressure in real time while the car is in motion.

[0100] It should be noted that each wheel of a car (a car may include four wheels: the left front wheel, the right front wheel, the left rear wheel, and the right rear wheel) is equipped with a TPMS so that the TPMS can monitor the tire pressure of the corresponding wheel in real time; to prevent the tire pressure from being higher or lower than the standard pressure, which may affect driving safety.

[0101] Taking a first preset threshold of 2.3 bar as an example. Specifically, in order to ensure the safety of the car during driving and avoid safety hazards caused by insufficient tire pressure, the car uses TPMS to determine whether the current tire pressure is less than 2.3 bar at preset time intervals (e.g., ten minutes, thirty minutes, or one hour).

[0102] It should be noted that 2.3 bar can be understood as the minimum standard tire pressure for a car. The standard tire pressure varies for each car model, and must be specified based on the specific vehicle.

[0103] S406, the sound source prompting device corresponding to the position of the vehicle control and the first device emits a prompting sound.

[0104] Taking the left front wheel of a car as an example, the first device refers to the car wheel with an air pressure of less than 2.3 bar.

[0105] Specifically, the vehicle uses a TPMS (Tire Pressure Monitoring System) to check the tire pressure of the car's wheels every ten minutes (using a preset time interval of ten minutes as an example). When the tire pressure of the left front tire is detected to be less than 2.3 bar, it is determined that the tire pressure of the left front tire is insufficient, posing a safety hazard. At this time, the speaker corresponding to the left front tire will emit a warning sound. It should be noted that the speaker corresponding to the left front tire can be linked to a speaker installed inside the left front door. When the tire pressure of the left front tire is detected to be less than 2.3 bar, the speaker located inside the left front door will emit a warning sound.

[0106] In some embodiments, the preset state can be a first preset state or a second preset state. The first preset state is when the tire pressure is less than a first preset threshold and greater than a second preset threshold, and the second preset state is when the tire pressure is less than or equal to a second preset threshold.

[0107] Taking a second preset threshold of 2.1 bar as an example, the first preset state is when the tire pressure is less than 2.3 bar and greater than 2.1 bar, and the second preset state is when the tire pressure is less than or equal to 2.1 bar. It can be understood that the first preset state is when the car's wheels and tires are in a low-pressure state, and the second preset state is when the car's wheels and tires are in an ultra-low-pressure state.

[0108] Taking the left front wheel of a car as an example, when the car detects through TPMS that the tire pressure of the left front wheel is less than 2.3 bar but greater than 2.1 bar, it indicates that the tire pressure of the left front wheel is in a low-pressure state and there is a safety hazard. At this time, the speaker corresponding to the left front wheel will emit a warning sound in the first manner.

[0109] When the car's TPMS detects that the tire pressure of the left front wheel is less than 2.1 bar, it indicates that the tire pressure of the left front wheel is in an extremely low pressure state, and there is a serious safety hazard to the left front wheel. At this time, the speaker corresponding to the left front wheel will emit a warning sound in a second manner.

[0110] It should be noted that the difference between the first and second methods lies in the volume or frequency of the warning tone emitted by the speaker; the different volumes or frequencies of the warning tone can be used to distinguish the different low pressure states of the car's wheel tires.

[0111] Specifically, the difference between the first and second methods lies in the volume of the warning sound emitted by the speaker. The car's infotainment system can be set to a volume lower when the left front tire pressure is low than when it is extremely low. The tire pressure status of the left front tire is determined based on the volume of the warning sound emitted by the speaker. The louder the sound, the lower the tire pressure, the more urgent the situation, and the more serious the safety hazard.

[0112] The difference between the first and second methods lies in the frequency of the warning tone emitted by the speaker. The car's infotainment system can be set to use a frequency lower than the frequency used when the left front tire pressure is low. The left front tire pressure is determined based on the frequency of the warning tone emitted by the speaker. The higher the frequency, the lower the tire pressure, the more urgent the situation, and the more serious the safety hazard, prompting the user to eliminate the safety hazard as soon as possible.

[0113] In some embodiments, the prompt tone emitted by the speaker may also be determined by both volume and frequency, and the specific settings can be configured according to actual conditions. This application does not impose any limitations on this.

[0114] To more accurately understand the tire pressure status, in addition to the aforementioned division of preset states into a first preset state and a second preset state, some embodiments may further divide the preset states into more states, each corresponding to a different pressure range. Each pressure range indicates that the tire is in a different low-pressure state. The lower the pressure, the more urgent the tire situation, and the louder or more frequent the corresponding warning sound.

[0115] In some embodiments, the tire pressure of the left front wheel may also be within a high-pressure range. Specifically, the preset states may also be a third preset state and a fourth preset state. Specifically, the third preset state may be a high-pressure state when the tire pressure is less than 2.5 bar and greater than 3.0 bar, and the fourth preset state may be an ultra-high-pressure state when the tire pressure is greater than 3.0 bar. The specific high-pressure state of the left front wheel tire is distinguished by the volume and frequency of the warning sound emitted by the speaker, so as to implement corresponding measures to avoid damage to the left front wheel caused by high pressure (high pressure and ultra-high pressure) and affect driving safety.

[0116] It should be noted that the above discussion on tire pressure is based on the left front wheel as an example; in some embodiments, it may also be the right front wheel, left rear wheel, and right rear wheel, which will not be elaborated here.

[0117] When the embodiments of this application are executed, if the tire pressure of the left front wheel is detected to be low, ultra-low, high, or ultra-high, the vehicle's infotainment system, controlled by a speaker located inside the left front door, emits a warning sound. The driver (or passenger) can directly know from the source of the warning sound that the tire pressure of the left front wheel is abnormal (low, ultra-low, high, or ultra-high), saving the driver (or passenger) time in finding the location of the abnormal wheel. At the same time, it also provides the driver (or passenger) with certainty about the location of the abnormal wheel, thereby reducing the anxiety caused by the driver (or passenger) in finding the location of the abnormal wheel.

[0118] Figure 5 This is a third illustrative flowchart of a sound source prompting method provided in an embodiment of this application.

[0119] Please see Figure 5 The device can be a car window, and the default state is that the car window is not closed.

[0120] For example, such as Figure 5 As shown, sound source prompting methods may include:

[0121] S502, when the vehicle's engine is detected to be off, the current state of each of the plurality of devices is obtained, and for each device, the vehicle determines whether the current state of the device is a preset state.

[0122] Specifically, a vehicle can determine that its engine is off by detecting that the pointer on the instrument panel is stationary, or by detecting that the vehicle body is stationary, etc. In some embodiments, other methods can also be used to detect that the vehicle's engine is off; this application is not limited to these methods and can be set according to actual conditions.

[0123] When the vehicle's transmitter is detected to be off, the vehicle uses a window closure detection device to detect the closure status of the car's windows. The window closure detection device can be a CAN (Controller Area Network) bus window lifter or other window closure detection devices; this application does not impose specific limitations and can be configured according to actual needs.

[0124] It should be noted that each window of the vehicle (including but not limited to the following windows that can be opened and closed: the left front door window, the right front door window, the left rear door window, the right rear door window, and the sunroof) is equipped with a window closure detection device to detect the closure status of the corresponding window and prevent property damage or damage to items inside the vehicle caused by an open window.

[0125] S504, the sound source prompting device corresponding to the position of the vehicle control and the first device emits a prompting sound.

[0126] Taking the left front door window as an example, the first device refers to the unclosed window in the vehicle.

[0127] For example, taking the left front door window as an example, when the vehicle detects that the left front door window is not closed through the window closure detection device, the speaker corresponding to the left front door window emits a warning sound. It should be noted that the speaker corresponding to the left front door window can be installed inside the left front door. When the left front door window is detected to be not closed, the speaker located inside the left front door emits a warning sound.

[0128] In the implementation of this embodiment, when the vehicle detects that the left front door window is not closed, the vehicle can control the speaker located in the left front door to emit a warning sound via the vehicle's infotainment system. The driver (or passenger) can directly know from the source of the warning sound that the left front door window is not closed, saving the driver (or passenger) time in finding the location of the unclosed window. At the same time, it also gives the driver (or passenger) certainty about the location of the unclosed window, thereby reducing the anxiety caused by the driver (or passenger) searching for the location of the unclosed window.

[0129] Figure 6 This is a fourth schematic flowchart of a sound source prompting method provided in an embodiment of this application.

[0130] Please see Figure 6 The device can be a seat belt, and the preset state is that the seat belt is not being worn properly.

[0131] For example, such as Figure 6 As shown, sound source prompting methods may include:

[0132] S602, the vehicle obtains the current state of each of the multiple devices, and for each device, determines whether the current state of the device is a preset state.

[0133] Please refer to step S202 for details, which will not be elaborated here.

[0134] In some embodiments, when there are multiple devices whose current state is a preset state, the following steps are further included:

[0135] S604, the sound source prompting devices corresponding to each position of the multiple first devices controlling the vehicle emit prompt sounds in sequence.

[0136] Specifically, the first device is the device among multiple devices whose current state is a preset state.

[0137] For example, consider the front left seat, front right seat, and rear left seat as multiple devices. If it is determined that all three seats are occupied and the seat belts are not being worn, the vehicle control system will sequentially issue warning sounds to the speakers corresponding to the front left seat, front right seat, and rear left seat.

[0138] Specifically, the speaker corresponding to the left front seat can emit a warning sound first, followed by the speaker corresponding to the right front seat, and finally the speaker corresponding to the left rear seat. This further improves the accuracy for the driver (or passenger) in determining the location of the seat where the seatbelt is not being worn properly, and saves the driver (or passenger) time in searching for the seat where the seatbelt is not being worn properly.

[0139] In some embodiments, the following steps may also be included:

[0140] S606, the sound source prompting device corresponding to the position of the vehicle control and the first device emits a prompting sound with content related to the position.

[0141] Specifically, the first device is the device among multiple devices whose current state is a preset state.

[0142] For example, consider the front left-hand seat. When it is detected that someone is occupying the front left-hand seat and the seatbelt is not properly fastened, the speaker corresponding to the front left-hand seat emits a warning sound. The warning sound may include the message "Front left-hand seatbelt not fastened." The warning sound has specific content, including the specific location of the seat. The driver can determine the location of the seat without a properly fastened seatbelt based on the warning sound, thus improving the convenience for the driver (or passenger) to locate the seat without a properly fastened seatbelt.

[0143] It should be noted that the scheme of emitting prompts related to the location and content of the sound source prompt device is not limited to seat belts. In some embodiments, this scheme can also be applied to doors, windows, turn signals, and wheels, etc. Specifically, when the vehicle detects that the left front door is not closed, the speaker corresponding to the left front door emits a "left front door not closed" prompt. When the vehicle detects that the left front door window is not closed, the speaker corresponding to the left front door window emits a "left front door window not closed" prompt. When the vehicle detects that the left turn signal is on, the speaker corresponding to the left turn signal emits a "vehicle turning left" prompt. In this way, the driver can determine the location of the device currently in a preset state based on the content of the prompt, improving the convenience for the driver to identify the device currently in a preset state.

[0144] It should be noted that the content of the prompt sound can be set according to the specific device and the location of the device, and this application does not impose any restrictions.

[0145] During the execution of the embodiments of this application, when the vehicle detects that the current state of the device is a preset state, the vehicle can control the sound source prompting device corresponding to the device's location via the vehicle's infotainment system to emit a prompt sound. The driver (or passenger) can directly know the location of the device in the preset state based on the location source of the prompt sound, saving the driver (or passenger) time in searching for the device in the preset state; at the same time, it can also give the driver (or passenger) certainty about the location of the device in the preset state, thereby reducing the anxiety caused by the driver (or passenger) searching for the location of the device in the preset state.

[0146] Furthermore, when there are multiple devices in the vehicle currently in a preset state, the devices will emit prompts in sequence according to a pre-set order to prevent multiple prompts from being emitted simultaneously, which would prevent the user from accurately identifying the location of the device currently in the preset state. This can improve the accuracy of the driver (or passenger) in determining the location of a seat where someone is sitting but not wearing a seatbelt, and save the driver (or passenger) time in finding the location of a seat where someone is sitting but not wearing a seatbelt.

[0147] Optionally, the multiple devices whose current state is a preset state belong to the same type of device.

[0148] For example, taking vehicle windows as an example, when the left front door window, right front door window, left rear door window, and right rear door window are all open, a warning tone can be emitted sequentially: "Left front door window not closed" for the left front door window; "Right front door window not closed" for the right front door window; "Left rear door window not closed" for the left rear door window; and "Right rear door window not closed" for the right rear door window. This allows the driver (or passenger) to directly determine the location of the open window based on the device and direction indicated in the warning tone, improving the accuracy of the driver's (or passenger's) judgment of the open window's location and saving the driver's (or passenger's) time in searching for the open window.

[0149] Optionally, the multiple devices whose current state is a preset state belong to different types of devices.

[0150] For example, taking car windows and doors as an example, when the left front door, right front door, left front door window, and right front door window are all not closed, a prompt tone corresponding to the left front door ("left front door not closed"), the right front door ("right front door not closed"), the left front door window ("left front door window not closed"), and the right front door window ("right front door window not closed") can be emitted sequentially. Thus, the driver (or passenger) can directly determine the location of the unclosed window based on the device and direction included in the prompt tone, improving the accuracy of the driver (or passenger) in judging the location of the unclosed window and saving the driver (or passenger) time in finding the location of the unclosed window.

[0151] Furthermore, the prompt tone includes specific prompts, such as the exact location of the seat. The driver can determine the location of the seat where the driver is not wearing a seatbelt based on the prompt tone, thus improving the convenience for the driver (or passenger) to locate the seat where the driver is not wearing a seatbelt.

[0162] In some embodiments, the preset state is a first preset state or a second preset state. The first preset state is when the tire pressure is less than the first preset threshold and greater than the second preset threshold, and the second preset state is when the tire pressure is less than or equal to the second preset threshold.

[0163] Status acquisition module 710 includes:

[0165] The fourth judgment unit is used to control the sound source prompting device corresponding to the position of the first device to emit a prompting sound in a second manner if the current state of the first device is the second preset state.

[0166] Wherein, the volume of the first method is less than the volume of the second method, and / or, the frequency of the first method is less than the frequency of the second method.

[0167] In some embodiments, the device is a vehicle window, and the preset state is that the vehicle window is not closed;
