[0086] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0087] To remind drivers to check their vehicles, this application provides a vehicle warning method that can be applied to in-vehicle devices installed in vehicles.

[0088] The aforementioned vehicles can be school buses, public buses, passenger vehicles, etc.

[0089] The vehicle warning method provided in this application will be described below through specific embodiments.

[0090] See Figure 1 , Figure 1 This is a flowchart illustrating the first vehicle warning method provided in this application embodiment. In this embodiment, the method includes the following steps S101-S103.

[0091] Step S101: Obtain the vehicle's location.

[0092] The vehicle location mentioned above can be the vehicle's GPS (Global Positioning System) information.

[0093] Specifically, the vehicle's location can be obtained through either of the following two methods.

[0094] In the first implementation, the vehicle may be equipped with the aforementioned on-board equipment and a positioning device for determining the vehicle's location. When the on-board equipment obtains the vehicle's location, it can obtain the vehicle's location determined by the positioning device.

[0095] In the second implementation, the aforementioned vehicle-mounted device can have a vehicle positioning function, so that the vehicle-mounted device can call the vehicle positioning function to determine the vehicle's location.

[0096] In addition, when obtaining the vehicle's location, it is possible to obtain the vehicle's real-time location or the vehicle's location periodically.

[0097] Step S102: Monitor whether the vehicle is turned off.

[0098] Specifically, the vehicle engine can be detected as off using either of the following two methods.

[0099] In the first implementation, after the vehicle detects that the engine is off, it can send an engine off signal to the on-board equipment. After receiving the engine off signal, the on-board equipment can determine that the vehicle has been turned off.

[0100] In the second implementation method, the vehicle engine's operating status can be monitored to determine whether the vehicle is off. If the engine is stopped, the vehicle is off; if the engine is running, the vehicle is still running.

[0101] For example, the engine speed can be obtained. If the engine speed is zero, it means that the engine is stopped and the vehicle is turned off. If the engine speed is not zero, it means that the engine is working and the vehicle is not turned off.

[0102] In addition, when obtaining the vehicle's position in step S101 above, the vehicle's position at the time of engine shutdown can be obtained after the vehicle is detected to be off.

[0103] Step S103: If the vehicle is turned off and the vehicle location indicator is located in the warning area, control the warning device installed on the vehicle to output a warning signal.

[0104] Specifically, if the onboard equipment detects that the vehicle is turned off and determines that the vehicle is in the warning area when it is turned off, it can control the aforementioned warning equipment to output a warning signal.

[0105] In one embodiment of this application, the aforementioned warning device is a loudspeaker. When the vehicle-mounted device controls the warning device to output a warning signal, the vehicle-mounted device can send a broadcast command to the loudspeaker, causing the loudspeaker to respond to the broadcast command and broadcast according to preset broadcast content to remind the driver to check the vehicle.

[0106] The specific implementation method for determining that the vehicle is in the warning area when the vehicle is turned off can be found in subsequent embodiments, and will not be described in detail here.

[0107] As can be seen from the above, when the solution provided in the embodiments of this application is used for vehicle warning, if the vehicle is detected to be off and the vehicle location indicates that the vehicle is in the warning area, the warning device installed on the vehicle can be controlled to output a warning signal, thereby reminding the driver to check the vehicle.

[0108] In addition, the conditions for the vehicle-mounted equipment to control the warning device to output a warning signal include both the vehicle being turned off and the vehicle being located in the warning area. This can prevent the vehicle-mounted equipment from mistakenly controlling the warning device to send a warning signal when the vehicle is outside the warning area or when the vehicle is not turned off, thereby improving the accuracy of vehicle warnings.

[0109] The following describes three ways to implement the determination by the on-board equipment that the vehicle is in the warning area when the engine is turned off in step S103 above.

[0110] In the first implementation, the vehicle-mounted equipment can establish a communication connection with the early warning platform, which can be understood as a platform that manages vehicle early warnings.

[0111] In this scenario, after detecting that the vehicle has turned off, the onboard equipment can send the vehicle's location at the time of shutdown to the warning platform. Upon receiving the vehicle's location, the warning platform can determine whether the vehicle is within the warning zone. If it is, it sends a warning command to the onboard equipment. Thus, the onboard equipment receives the warning command from the warning platform after confirming the vehicle's location within the warning zone. Therefore, if the onboard equipment receives the warning command, it means the warning platform has determined the vehicle is within the warning zone. This allows the onboard equipment to respond to the warning command, accurately control the output of the warning signal, and facilitate unified management of vehicle warning tasks by the warning platform.

[0112] Before determining whether a vehicle is located in a warning area, the warning platform can pre-determine the warning area.

[0113] For example, the early warning platform can determine the early warning area through either of the following two methods.

[0114] In one implementation, the early warning platform can obtain the location of the area input by the user and use the area indicated by the location input by the user as the early warning area.

[0115] In another implementation, the warning platform can obtain the vehicle's preset driving route and determine the vehicle's destination based on the driving route, thereby determining the area where the vehicle's destination is located as the warning area.

[0116] In one embodiment of this application, see [link to embodiment]. Figure 2 , Figure 2 This is a schematic diagram illustrating the interaction between a first type of vehicle-mounted device and an early warning platform, provided as an embodiment of this application. Figure 2 In this process, the interaction between the vehicle-mounted equipment and the early warning platform includes the following steps S201-S205.

[0117] Step S201: The on-board equipment obtains the vehicle's location and monitors whether the vehicle is turned off;

[0118] Step S202: After detecting that the vehicle has been turned off, the on-board equipment sends the vehicle's location at the time of engine shutdown to the early warning platform;

[0119] Step S203: After receiving the vehicle location, the early warning platform determines whether the vehicle is located in the early warning area based on the vehicle location;

[0120] Step S204: After determining that the vehicle is located in the warning area, the warning platform sends a warning command to the on-board equipment;

[0121] Step S205: After receiving the warning command, the vehicle-mounted equipment responds to the warning command by controlling the warning equipment to output a warning signal.

[0122] In the second implementation, after establishing a communication connection between the vehicle-mounted device and the early warning platform, the vehicle-mounted device can send the collected vehicle location to the early warning platform each time it successfully collects the vehicle's location. Each time the early warning platform receives the vehicle location, it can determine whether the vehicle is within the warning area. If it confirms that the vehicle is within the warning area, it sends a first notification to the vehicle-mounted device. If it confirms that the vehicle has left the warning area, it sends a second notification to the vehicle-mounted device.

[0123] Each time the early warning platform receives a vehicle location, it can determine whether the vehicle is located in the warning area based on the received vehicle location and obtain a judgment result. In one implementation, when the early warning platform sends a notification to the vehicle-mounted device, it can send a notification corresponding to the judgment result after obtaining each judgment result.

[0124] For example, after receiving vehicle location 1, the early warning platform determines that the vehicle is located in the warning area based on vehicle location 1, and can then send a first notification to the on-board equipment. If the early warning platform receives vehicle location 2 after receiving vehicle location 1, and also determines that the vehicle is located in the warning area based on vehicle location 2, the early warning platform can send a first notification to the on-board equipment again.

[0125] In another implementation, the early warning platform can compare each judgment result with the previous judgment result. If they are different, it can send a notification corresponding to the judgment result to the vehicle-mounted device. If they are the same, it can choose not to send any notification to the vehicle-mounted device.

[0126] For example, after receiving vehicle location 3, the warning platform determines that the vehicle is within the warning area based on vehicle location 3, and can then send a first notification to the onboard device. If the warning platform receives vehicle location 4 after receiving vehicle location 3, and also determines that the vehicle is within the warning area based on vehicle location 4, then no notification needs to be sent to the onboard device. If the warning platform receives vehicle location 5 after receiving vehicle location 4, and determines that the vehicle has left the warning area based on vehicle location 5, then a second notification can be sent to the onboard device.

[0127] The vehicle-mounted equipment can receive notifications sent by the warning platform. If it detects that the first notification has been received but the second notification has not been received, it means that the vehicle has entered the warning area and has not left the warning area. At this time, it can accurately determine that the vehicle is located in the warning area. Thus, the vehicle-mounted equipment can accurately control the warning equipment to output warning information when it detects that the vehicle is turned off, the first notification has been received, and the second notification has not been received, thereby improving the accuracy of vehicle warnings.

[0128] In one embodiment of this application, see [link to embodiment]. Figure 3 , Figure 3 This is a schematic diagram illustrating the interaction between a second type of vehicle-mounted device and an early warning platform, provided in an embodiment of this application. Figure 3 In this process, the interaction between the vehicle-mounted equipment and the early warning platform includes the following steps S301-S305.

[0129] Step S301: The on-board equipment obtains the vehicle's location and monitors whether the vehicle is turned off;

[0130] Step S302: After each successful acquisition of the vehicle's location, the on-board device sends the vehicle's location to the early warning platform;

[0131] Step S303: After receiving the vehicle location, the early warning platform determines whether the vehicle is located in the early warning area based on the vehicle location;

[0132] Step S304: The early warning platform sends a notification to the vehicle-mounted device based on the judgment result. If the judgment result is that the vehicle is in the early warning area, the notification sent is the first notification. If the judgment result is that the vehicle is not in the early warning area, the notification sent is the second notification.

[0133] Step S305: After receiving the notification, if the vehicle-mounted device detects that the first notification has been received, the second notification has not been received, and the vehicle engine is detected to be off, it controls the warning device to output a warning signal.

[0134] In the third implementation, the onboard device can pre-determine the aforementioned warning area. After detecting that the vehicle is turned off, it determines whether the vehicle is within the warning area based on the vehicle's position after the engine is turned off. If it determines that the vehicle is within the warning area after the engine is turned off, it controls the warning device to output a warning signal. In this way, the onboard device independently determines whether the vehicle is within the warning area and monitors whether the vehicle is turned off to control the output of the warning signal, eliminating the need for information exchange between the onboard device and the warning platform, thereby accelerating the vehicle warning efficiency.

[0135] There are several ways for onboard equipment to determine the warning area. For example, the warning area can be determined using either of the following two methods.

[0136] In one implementation, the on-board device can obtain the location of the area input by the user and use the area indicated by the location input by the user as the warning area.

[0137] In another implementation, the vehicle-mounted equipment can establish a communication connection with the early warning platform. In this way, the vehicle equipment can receive the location of the early warning area sent by the early warning platform, thereby determining the area indicated by the received location as the early warning area.

[0138] In the first implementation method where the vehicle is located in the warning area when the vehicle-mounted device determines that the vehicle is turned off, the vehicle-mounted device can also send a shutdown indicator to the warning platform when sending the vehicle's location when the vehicle is turned off, and receive a warning instruction sent by the warning platform after determining that the vehicle is turned off based on the shutdown indicator and that the vehicle is located in the warning area based on the vehicle's location.

[0139] Specifically, the aforementioned early warning platform can be a vehicle management platform with vehicle early warning management functions. In this case, the purpose of the vehicle-mounted device sending the vehicle location to the platform may not be for vehicle early warning. For example, the purpose of the vehicle-mounted device sending the vehicle location to the platform may be for vehicle navigation. Therefore, when the vehicle-mounted device sends the vehicle location when the vehicle is turned off, it can also send an engine shutdown indicator to the vehicle management platform. After receiving the vehicle location and the engine shutdown indicator, the vehicle management platform can determine that the vehicle is turned off based on the received engine shutdown indicator and determine that the received vehicle location is the location of the vehicle when it is turned off. After determining that the vehicle is turned off and that the vehicle is located in the early warning area based on the received vehicle location, the platform sends an early warning command to the vehicle-mounted device, so that the vehicle-mounted device can receive the early warning command.

[0140] Therefore, it can be seen that after the vehicle-mounted equipment detects that the vehicle has been turned off, it sends an engine shutdown indicator and the vehicle's location at the time of engine shutdown to the warning platform. This enables the warning platform to accurately determine the vehicle's location at the time of engine shutdown based on the engine shutdown indicator. As a result, when the warning platform determines that the vehicle has been turned off and is located in the warning area, it can accurately send a warning command to the vehicle-mounted equipment. In turn, the vehicle-mounted equipment can respond to the warning command and accurately control the output of the warning signal.

[0141] In the third implementation method where the vehicle is located within the warning zone when the on-board equipment determines that the vehicle is off, after the on-board equipment establishes a communication connection with the warning platform, and after detecting that the vehicle is off and determining that the vehicle is within the warning zone, but before controlling the warning equipment to output a warning signal, the on-board equipment can also send an engine shutdown notification to the warning platform. Upon receiving the engine shutdown notification, the warning platform can determine that the vehicle is off based on the notification and decide whether to send a warning command to the on-board equipment. If the warning platform decides to send a warning command to the on-board equipment, it does so. The on-board equipment can then receive the warning command and respond to it by executing the steps to control the warning equipment to output a warning signal. In this way, the warning platform can control the warning equipment in the vehicle to output a warning signal based on the warning command, thereby realizing the vehicle warning task management of the warning platform. When the warning platform establishes a communication connection with the on-board equipment of multiple vehicles, the warning platform can uniformly manage the vehicle warning tasks of each vehicle.

[0142] Specifically, the on-board equipment sends a shutdown notification to the warning platform when it detects that the vehicle is off and determines that the vehicle is in the warning area. Therefore, if the warning platform receives the shutdown notification, it can determine that the vehicle is off and that the vehicle is in the warning area. Based on this, the warning platform can also consider other factors to determine whether to send a warning command to the on-board equipment.

[0143] For example, after receiving a shutdown notification, the warning platform can determine whether the current time is within a preset time period. If it determines that the current time is within the preset time period, it will send a warning command to the vehicle-mounted equipment.

[0144] For example, the warning platform can record the operating status of the warning devices in the vehicle, such as whether they are on, off, or faulty. When the warning platform receives a shutdown notification, if the recorded operating status of the warning device in the vehicle is on, it can send a warning command to the onboard device.

[0145] In one embodiment of this application, see [link to embodiment]. Figure 4 , Figure 4 This is a schematic diagram illustrating the interaction between a third type of vehicle-mounted device and an early warning platform, provided in an embodiment of this application. Figure 4 In this process, the interaction between the vehicle-mounted equipment and the early warning platform includes the following steps S401-S405.

[0146] Step S401: The on-board equipment obtains the vehicle's location, determines whether the vehicle is in the warning area based on the vehicle's location, and monitors whether the vehicle is turned off;

[0147] Step S402: When the on-board equipment determines that the vehicle is off and the vehicle is located in the warning area, it sends an engine shutdown notification to the warning platform.

[0148] Step S403: After receiving the engine shutdown notification, the warning device determines whether to send a warning command to the vehicle-mounted equipment;

[0149] Step S404: If the warning device determines that it will send a warning command to the vehicle-mounted device, it sends a warning command to the vehicle-mounted device.

[0150] Step S405: After receiving the warning command, the vehicle-mounted equipment responds to the warning command by controlling the warning equipment to output a warning signal.

[0151] In one embodiment of this application, when the vehicle-mounted device establishes a communication connection with the early warning platform, after the vehicle-mounted device controls the early warning device to output an early warning signal, if it detects that a button installed at the rear of the vehicle's cargo compartment has been pressed, it can send an early warning cancellation notification to the early warning platform.

[0152] See Figure 5 , Figure 5 This is a schematic diagram of a vehicle warning scenario. Figure 5 In the vehicle shown, the warning device 501 can be installed at the front of the vehicle compartment, for example, on the top of the compartment above the driver; the button 502 for canceling the warning is installed at the rear of the vehicle compartment. When the on-board equipment controls the warning device 501 to output a warning signal to remind the driver to check the vehicle, the driver can walk from the front of the compartment to the rear and press the button 502 installed at the rear of the compartment, thus allowing the driver to check the vehicle while walking from the front to the rear.

[0153] Since button 502 is located at the rear of the vehicle, if the on-board equipment detects that button 502 has been pressed, it means that the driver has moved from the front of the vehicle to the rear, which means that the driver has inspected the vehicle. Therefore, after detecting that button 502 has been pressed, the on-board equipment can send a warning cancellation notification to the warning platform to notify the warning platform that the driver has completed the inspection. This helps the warning platform manage the vehicle warning tasks.

[0154] In one embodiment of this application, see [link to embodiment]. Figure 6 , Figure 6 This is a schematic diagram illustrating the interaction between a fourth type of vehicle-mounted device and an early warning platform, provided in an embodiment of this application. Figure 6 In this process, the interaction between the vehicle-mounted equipment and the early warning platform includes the following steps S601-S606.

[0155] Step S601: The on-board equipment obtains the vehicle's location and monitors whether the vehicle is turned off;

[0156] Step S602: After detecting that the vehicle has been turned off, the on-board equipment sends the vehicle's location at the time of engine shutdown to the early warning platform;

[0157] Step S603: After receiving the vehicle location, the early warning platform determines whether the vehicle is located in the early warning area based on the vehicle location;

[0158] Step S604: After determining that the vehicle is located in the warning area, the warning platform sends a warning command to the on-board equipment;

[0159] Step S605: After receiving the warning command, the vehicle-mounted equipment responds to the warning command by controlling the warning equipment to output a warning signal;

[0160] Step S606: After detecting that the button installed at the rear of the vehicle compartment has been pressed, the on-board equipment sends a warning cancellation notification to the warning platform.

[0161] In one embodiment of this application, during the information exchange between the vehicle-mounted device and the early warning platform, the early warning platform can record vehicle shutdown event information to facilitate the management of vehicle early warning tasks.

[0162] The aforementioned engine shutdown event information may include at least one of the following:

[0163] The time of engine shutdown, the time of issuing the warning signal, the time of receiving the warning signal, vehicle information, and the vehicle's position when the engine was shut down.

[0164] Corresponding to the vehicle warning method applied to in-vehicle equipment installed in vehicles described above, this application also provides a vehicle warning method applied to a warning platform.

[0165] In one embodiment of this application, see [link to embodiment]. Figure 7 The present invention provides a flowchart of a second vehicle warning method. In this embodiment, the method includes the following steps S701-S702.

[0166] Step S701: Obtain the vehicle's location information.

[0167] Specifically, the aforementioned vehicle-mounted equipment can obtain the vehicle's location information and send the obtained vehicle location information to the early warning platform, so that the vehicle-mounted platform can obtain the vehicle's location information sent by the vehicle-mounted equipment.

[0168] For example, in-vehicle equipment can obtain the real-time location of a vehicle and send the vehicle's real-time location information to the early warning platform, so that the early warning platform can receive the vehicle's real-time location information.

[0169] In addition, after obtaining the vehicle's real-time location, the on-board equipment can periodically send the vehicle's real-time location information to the early warning platform, so that the early warning platform can periodically receive the vehicle's real-time location information.

[0170] Step S702: If the location information includes the vehicle's engine off indicator, and the location information indicates that the vehicle is in the warning area, control the warning device installed on the vehicle to output a warning signal.

[0171] The aforementioned warning areas can be set manually or determined based on the vehicle's planned route.

[0172] For example, the area where the vehicle's planned route ends can be designated as a warning zone.

[0173] Specifically, after obtaining the vehicle's location information, the warning platform can detect whether the obtained location information includes the vehicle's engine off indicator, and determine whether the vehicle is within the warning area based on the obtained location information. If the warning platform detects that the obtained information includes the vehicle's engine off indicator, and determines that the vehicle is within the warning area based on the location information, it means that the vehicle has been turned off and has reached the designated warning area. At this time, it can control the warning equipment installed on the vehicle to output a warning signal.

[0174] For example, the early warning platform can control the early warning device to output early warning signals through either of the following two implementation methods.

[0175] In the first implementation, the early warning platform can send early warning commands to the vehicle-mounted equipment, so that the vehicle-mounted equipment responds to the early warning commands and controls the early warning equipment to output early warning signals.

[0176] In the second implementation, the early warning platform can interact with the early warning equipment, allowing the platform to directly control the equipment to output early warning signals.

[0177] As can be seen from the above, when applying the solution provided in the embodiments of this application for vehicle warning, after obtaining the vehicle's location information, if the warning platform detects that the location information includes the vehicle's engine shutdown indicator and determines that the vehicle is located in the warning area, it can control the warning device installed in the vehicle to output a warning signal, thereby reminding the driver to check the vehicle.

[0178] Corresponding to the above-mentioned vehicle warning method, this application also provides a vehicle warning device.

[0179] In one embodiment of this application, see [link to embodiment]. Figure 8 A schematic diagram of the structure of a first type of vehicle warning device is provided. In this embodiment, the device includes:

[0180] Location acquisition module 801 is used to obtain the vehicle's location;

[0181] The engine shutdown monitoring module 802 is used to monitor whether the vehicle is turned off.

[0182] The signal control module 803 is used to control the warning device installed on the vehicle to output a warning signal if the vehicle is turned off and the vehicle's position indicates that the vehicle is in a warning area.

[0183] As can be seen from the above, when the solution provided in the embodiments of this application is used for vehicle warning, if the vehicle is detected to be off and the vehicle location indicates that the vehicle is in the warning area, the warning device installed on the vehicle can be controlled to output a warning signal, thereby reminding the driver to check the vehicle.

[0184] In addition, the conditions for the vehicle-mounted equipment to control the warning device to output a warning signal include both the vehicle being turned off and the vehicle being located in the warning area. This can prevent the vehicle-mounted equipment from mistakenly controlling the warning device to send a warning signal when the vehicle is outside the warning area or when the vehicle is not turned off, thereby improving the accuracy of vehicle warnings.

[0185] In one embodiment of this application, the signal control module includes:

[0186] The location sending module is used to send the vehicle's location when the vehicle is turned off to the early warning platform;

[0187] The instruction receiving module is used to receive the warning instruction sent by the warning platform after determining that the vehicle is located in the warning area based on the vehicle's location.

[0192] The system receives a warning command from the warning platform after determining that the vehicle is off based on the engine shutdown indicator and that the vehicle is located in the warning area based on the vehicle's location.

[0193] As can be seen from the above, when using the solution provided in this application embodiment for vehicle warning, after the vehicle-mounted device detects that the vehicle is turned off, it sends a shutdown identifier and the vehicle's location when the vehicle is turned off to the warning platform. This enables the warning platform to accurately determine the vehicle location it receives based on the shutdown identifier, thus enabling the warning platform to accurately send a warning command to the vehicle-mounted device when it determines that the vehicle is turned off and that the vehicle is located in the warning area. Consequently, the vehicle-mounted device can respond to the warning command and accurately control the warning device to output a warning signal.

[0194] In one embodiment of this application, the apparatus further includes:

[0195] The information sending module is used to send the vehicle location to the early warning platform each time the vehicle location is successfully collected;

[0196] The notification receiving module is used to receive the first notification sent by the early warning platform after determining that the vehicle is located in the early warning area based on the vehicle's location;

[0197] The signal control module is specifically used for:

[0198] If the vehicle is turned off, and it is detected that the first notification has been received but the second notification has not been received, the warning device installed in the vehicle is controlled to output a warning signal. The second notification is a notification sent by the warning platform after determining that the vehicle has left the warning area based on the vehicle's location.

[0199] As can be seen from the above, by applying the solution provided in the embodiments of this application for vehicle early warning, the on-board equipment can accurately control the output of early warning information by the early warning equipment, thereby improving the accuracy of vehicle early warning.

[0200] In one embodiment of this application, the apparatus further includes:

[0201] The warning cancellation module is used to send a warning cancellation notification to the warning platform after detecting that a button installed at the rear of the vehicle's cargo compartment has been pressed.

[0202] As can be seen from the above, applying the solution provided in the embodiments of this application for vehicle early warning can help the early warning platform manage vehicle early warning tasks.

[0203] In one embodiment of this application, the signal control module includes:

[0204] The area determination submodule is used to determine whether the vehicle is located in the warning area based on the vehicle's position when the engine is turned off. If so, the signal control submodule is triggered.

[0205] The signal control submodule is used to control the warning equipment installed in the vehicle to output warning signals.

[0206] As can be seen from the above, when using the solution provided in this application embodiment for vehicle warning, the on-board equipment can determine whether the vehicle is in the warning area and monitor whether the vehicle is turned off to control the warning equipment to output the warning signal. There is no need for information interaction between the on-board equipment and the warning platform, which can speed up the vehicle warning efficiency.

[0207] In one embodiment of this application, the apparatus further includes:

[0208] The notification sending module is used to send a shutdown notification to the warning platform before the warning device installed in the vehicle outputs a warning signal;

[0209] The instruction acquisition module is used to acquire the warning instruction fed back by the warning platform based on the engine shutdown notification;

[0210] The instruction response module is used to trigger the signal control submodule in response to the warning instruction.

[0211] As can be seen from the above, by applying the solution provided in this application for vehicle early warning, the early warning platform can control the early warning devices in the vehicle to output early warning signals based on early warning commands, thereby realizing the vehicle early warning task management of the early warning platform. When the early warning platform establishes a communication connection with the on-board devices of multiple vehicles, the early warning platform can uniformly manage the vehicle early warning tasks of each vehicle.

[0212] In one embodiment of this application, see [link to embodiment]. Figure 9 A schematic diagram of a second type of vehicle warning device is provided. In this embodiment, the device includes:

[0213] Information acquisition module 901 is used to acquire vehicle location information;

[0214] The device control module 902 is used to control the warning device installed on the vehicle to output a warning signal if the location information includes the vehicle's engine off indicator and the location information indicates that the vehicle is located in a warning area.

[0215] As can be seen from the above, when applying the solution provided in the embodiments of this application for vehicle warning, after obtaining the vehicle's location information, if the warning platform detects that the location information includes the vehicle's engine shutdown indicator and determines that the vehicle is located in the warning area, it can control the warning device installed in the vehicle to output a warning signal, thereby reminding the driver to check the vehicle.

[0216] Corresponding to the above-mentioned vehicle warning method, this application also provides a vehicle warning system.

[0217] In one embodiment of this application, see [link to embodiment]. Figure 10A schematic diagram of a vehicle warning system is provided. In this embodiment, the system includes: a warning platform 1001 and an on-board device 1002; wherein,

[0218] The vehicle-mounted device 1002 is used to obtain the vehicle's location, monitor whether the vehicle is turned off, and send the vehicle's location when the vehicle is turned off to the early warning platform 1001.

[0219] The early warning platform 1001 is used to receive the vehicle's location when the vehicle is turned off, and determine whether the vehicle is in the early warning area based on the received vehicle location. If so, it sends an early warning command to the vehicle-mounted device 1002.

[0220] The vehicle-mounted device 1002 is also used to receive the warning command and, in response to the warning command, control the warning device installed in the vehicle to output a warning signal.

[0221] As can be seen from the above, when using the solution provided in the embodiments of this application for vehicle early warning, the on-board equipment can accurately control the output of early warning signals by the early warning equipment, and the early warning platform sends early warning instructions to the on-board equipment to realize vehicle early warning, which is conducive to the unified management of vehicle early warning tasks by the early warning platform.

[0222] In addition, the conditions for the warning device to output a warning signal include both the vehicle being turned off and the vehicle being located within the warning area. This can prevent the warning device from sending a false warning signal when the vehicle is outside the warning area or when the vehicle is not turned off, thereby improving the accuracy of vehicle warnings.

[0223] In one embodiment of this application, the vehicle-mounted device is specifically used to send a shutdown indicator and the vehicle's location when the vehicle is turned off to the warning platform.

[0224] The warning platform is specifically used to receive the engine shutdown indicator and the vehicle's location when the vehicle is turned off, and after determining that the vehicle is turned off based on the engine shutdown indicator and that the vehicle is located in the warning area based on the received vehicle location, it sends a warning command to the vehicle-mounted device.

[0225] As can be seen from the above, when using the solution provided in this application embodiment for vehicle warning, after the vehicle-mounted device detects that the vehicle is turned off, it sends a shutdown identifier and the vehicle's location when the vehicle is turned off to the warning platform. This enables the warning platform to accurately determine the vehicle location it receives based on the shutdown identifier, thus enabling the warning platform to accurately send a warning command to the vehicle-mounted device when it determines that the vehicle is turned off and that the vehicle is located in the warning area. Consequently, the vehicle-mounted device can respond to the warning command and accurately control the warning device to output a warning signal.
