[0032] It should be noted that the information (including but not limited to vehicle temperature, flammable gas concentration, etc.), data (including but not limited to data for analysis, stored data, displayed data, etc.) and signals involved in the present application are all authorized by the user or fully authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of relevant countries and regions. For example, the framework data involved in the present application is obtained under full authorization.

[0033] Figure 1 The structural block diagram of a computer system 100 provided by an exemplary embodiment of the present application is shown. The computer system 100 can be implemented as a system architecture of a vehicle warning method. The computer system 100 includes a vehicle 110 and a terminal 120.

[0034] The vehicle 110 includes a vehicle-mounted terminal, and the vehicle includes at least one of a fuel automobile, a hybrid automobile, an electric automobile, a fuel cell automobile, etc., which is not limited by the embodiments of the present application. The terminal 120 includes but is not limited to a vehicle-mounted terminal, a mobile phone, a computer, a smart voice interaction device, a smart home appliance, an aircraft, etc.

[0035] In some embodiments, the terminal 120 is implemented as a mobile control terminal of the vehicle 110, and the terminal 120 can control the vehicle 110 to perform a target operation (for example: parking, closing the window, starting, etc.). Illustratively, the terminal 120 has a client of a target application installed and running therein, and the target application includes at least one of a vehicle control application, an instant messaging application, a navigation application (for example: a map application), and an application with a vehicle control function, which is not limited by the embodiments of the present application. In addition, the form of the target application is not limited by the present application, including but not limited to an App (Application) installed in the terminal 120, a mini program, etc., and can also be in the form of a web page.

[0036] Optionally, the vehicle 110 and the terminal 120 communicate through a wireless network (such as 4G / 5G, Wi-Fi, etc.) or a wired connection (such as USB, Bluetooth, etc.).

[0037] In some embodiments, the computer system 100 further includes a server 130, which can be a standalone physical server, a server cluster composed of multiple physical servers, or a distributed system, or a cloud server providing cloud computing services.

[0038] Illustratively, if the server 130 is implemented as a cloud server, the vehicle 110 and the server 130 communicate through a wireless network, and the terminal 120 and the server 130 communicate through a wireless network.

[0039] Optionally, the vehicle pre-warning method provided by the embodiments of the present application can be executed by the vehicle 110, the terminal 120, or the server 130; or executed by any two of the vehicle 110, the terminal 120, and the server 130; or executed by the vehicle 110, the terminal 120, and the server 130, which is not limited in the embodiments of the present application.

[0040] Illustratively, the vehicle 110 is installed with a temperature sensor and a gas sensor. The temperature sensor collects the internal temperature of the vehicle 110, such as the engine exhaust temperature. The gas sensor collects the concentration of flammable gas in the internal air of the vehicle 110. After collecting the vehicle temperature and the flammable gas concentration, it is determined in the vehicle 110 whether the vehicle temperature and / or the flammable gas concentration meet the preset warning condition, such as whether the vehicle temperature is greater than or equal to the first preset temperature. If yes, it is determined that the vehicle has a risk of spontaneous combustion, and a warning information is generated. Alternatively, it is determined whether the flammable gas concentration is greater than or equal to the first preset concentration. If yes, it is determined that the vehicle has a risk of spontaneous combustion, and a warning information is generated. After the vehicle 110 generates the warning information, the vehicle 110 generates operation data corresponding to a first warning operation through the warning information, and controls the vehicle 110 to execute the first warning operation through the operation data, for example, controls the vehicle terminal in the vehicle 110 to display a spontaneous combustion warning prompt. In addition, the vehicle 110 also sends the warning information to the terminal 120, and the terminal 120 executes a second warning according to the warning information. Alternatively, the vehicle 110 sends the warning information to the server 130, and the server 130 generates operation data corresponding to a second warning operation according to the warning information, and sends the operation data to the terminal 120. The terminal 120 executes the second warning operation according to the operation data, for example, displays a spontaneous combustion warning notification on the terminal 120.

[0041] Optionally, the above-mentioned early warning information can also be generated by the server 130, and when the vehicle collects the vehicle temperature and the combustible gas concentration, the vehicle temperature and the combustible gas concentration are sent to the server 130, and the server 130 judges the spontaneous combustion risk. When it is judged that there is a spontaneous combustion risk, the early warning information is generated. After the server 130 generates the early warning information, operation data corresponding to the first early warning operation and operation data corresponding to the second early warning operation are generated according to the early warning information, the operation data corresponding to the first early warning operation is sent to the vehicle 110, and the vehicle 110 will execute the first early warning operation according to the operation data; the operation data corresponding to the second early warning operation is sent to the terminal 120, and the terminal 120 will execute the second early warning operation according to the operation data.

[0042] Optionally, the server 130 can also be implemented as a node in a blockchain system.

[0043] With the continuous progress of society and the continuous innovation of technology, the automobile field has experienced rapid development and has become an indispensable part of modern social life. With the continuous increase of the number of automobiles, the automobile safety problem has become increasingly prominent, among which the automobile spontaneous combustion problem has attracted particular attention. In the related technology, a smoke alarm is usually installed on the automobile, which is used to detect the smoke concentration generated in the automobile. If the concentration of the smoke is greater than the preset concentration, the alarm system inside the vehicle will be triggered, and the automobile will emit a high-decibel sound to remind the passengers in the automobile. However, the smoke alarm will only trigger the alarm when the concentration of the smoke reaches a certain threshold, which means that in the initial stage of the fire, the smoke alarm may not be able to issue an alarm in time because the concentration of the smoke has not reached the alarm threshold, resulting in the missed best fire extinguishing opportunity and high risk of automobile spontaneous combustion.

[0044] Based on this, the present application provides a vehicle early warning method, which can issue an early warning when the risk of automobile spontaneous combustion increases, thereby reminding the personnel in the vehicle or other personnel (for example, passing pedestrians, etc.) to take timely measures to reduce the risk of automobile spontaneous combustion. In addition, the early warning information is also sent to other terminals connected with the vehicle terminal, and the other terminals are also controlled to execute corresponding early warning operations, thereby expanding the early warning range and ensuring that the early warning information can be known by relevant personnel (for example, users using the vehicle control application) in the state that the vehicle is unoccupied, so that the relevant personnel can respond more quickly to minimize the risk of automobile spontaneous combustion.

[0045] The vehicle early warning method provided by the embodiments of the present application is described below.

[0046] In combination with the above introduction, Figure 2 is a flowchart of a vehicle early warning method provided by the embodiments of the present application. The method is applied to, for example, Figure 1The method is as follows steps 210 to steps 240, taking the vehicle 110 shown as an example.

[0047] Step 210, obtaining target detection information corresponding to the vehicle.

[0048] Among them, the target detection information refers to the detection information related to the vehicle spontaneous combustion risk. Optionally, the target detection information includes at least one of the following information:

[0049] 1. Vehicle temperature

[0050] The vehicle temperature is used to indicate the internal temperature of the vehicle. Optionally, the vehicle temperature includes at least one of the following:

[0051] The vehicle temperature is used to indicate the internal temperature of the vehicle. Optionally, the vehicle temperature includes at least one of the following:

[0052] The vehicle temperature is used to indicate the internal temperature of the vehicle. Optionally, the vehicle temperature includes at least one of the following:

[0053] Optionally, the vehicle temperature is obtained by a temperature sensor installed in the vehicle. The temperature sensor includes a resistance thermometer, a thermocouple, a thermistor, an infrared temperature sensor, a pressure temperature sensor, and an optical fiber temperature sensor.

[0054] Illustratively, the vehicle temperature includes the engine exhaust temperature. The engine exhaust temperature corresponding to the vehicle is obtained by a temperature sensor installed in the vehicle, which is installed near the engine exhaust manifold or the turbocharger outlet to ensure accurate measurement of the exhaust temperature.

[0055] 2. Concentration of flammable gas

[0056] The concentration of flammable gas is used to indicate the concentration of flammable gas in the internal air of the vehicle.

[0057] Illustratively, the flammable gas refers to the gas that can react with oxygen in the air under certain conditions. The presence of flammable gas in the internal air of the vehicle may be due to fuel leakage, incomplete combustion or other reasons. Different types of cars use different fuels, so the flammable gas produced is different. Optionally, the flammable gas includes at least one of the following gases:

[0058] (1) Gasoline gas: using gasoline as fuel, if leakage or incomplete combustion occurs during the combustion of gasoline, combustible gasoline gas such as unburned gasoline vapor, carbon monoxide and hydrogen may be generated.

[0059] (2) Diesel gas: using diesel as fuel, and also possible leakage or incomplete combustion to generate combustible diesel gas such as unburned diesel vapor, carbon monoxide and a small amount of hydrogen.

[0060] Among them, the unburned gasoline vapor or diesel vapor is mainly composed of hydrocarbons such as alkanes, alkenes and aromatic hydrocarbons.

[0061] (3) Natural gas: using diesel as fuel, the combustible gas that may leak is mainly natural gas itself. Natural gas is mainly composed of methane.

[0062] It should be noted that the above examples of combustible gas are only illustrative, and the embodiments of the present application are not limited thereto. For example, for a car containing a battery system (such as an electric car, a hybrid electric car, etc.), if the battery system of the electric car fails, hydrogen or other combustible gas may be generated.

[0063] Optionally, the combustible gas concentration corresponding to the vehicle is obtained through a gas sensor installed in the vehicle. The gas sensor includes an electrochemical gas sensor, a semiconductor gas sensor, an infrared gas sensor, etc., and the embodiments of the present application are not limited thereto.

[0064] Optionally, the combustible gas concentration obtained above can refer to the concentration of a single type of combustible gas, such as the methane concentration in the internal air of the vehicle; or the concentration of multiple types of combustible gas, such as the methane concentration and the ethane concentration in the internal air of the vehicle; or the average value of the concentration of multiple types of combustible gas, such as the average value of the methane concentration and the ethane concentration in the internal air of the vehicle; or the minimum value of the concentration of multiple types of combustible gas, such as the methane concentration in the internal air of the vehicle being greater than the ethane concentration, and the combustible gas concentration referring to the ethane concentration.

[0065] Step 220, in the case that the target detection information meets the preset warning condition, determining the warning information based on the target detection information.

[0066] Optionally, the case that the target detection information meets the preset warning condition includes at least one of the following cases:

[0067] 1. In the case that the temperature of the vehicle is within a first temperature range, determining the warning information based on the target detection information.

[0068] For example, the vehicle temperature in the first temperature range means that the vehicle temperature is greater than or equal to a first preset temperature, for example, the engine exhaust temperature is greater than or equal to 580 degrees; or the vehicle temperature belongs to a first temperature interval, wherein the minimum temperature in the first temperature interval is greater than or equal to the first preset temperature, for example, the vehicle temperature belongs to a temperature interval of [580 degrees, 600 degrees].

[0069] That is, when it is detected that the internal temperature of the vehicle is too high, it is determined that the vehicle has a risk of spontaneous combustion, and at this time, a spontaneous combustion warning is performed.

[0070] 2. In the case that the combustible gas concentration is in the first concentration range, the warning information is determined based on the target detection information.

[0071] For example, the combustible gas concentration in the first concentration range means that the combustible gas concentration is greater than or equal to a first preset concentration, for example, the methane concentration in the internal air of the vehicle is greater than or equal to 5% (when methane is mixed with air, if the volume concentration of methane in the air is greater than or equal to 5%); or the methane concentration belongs to a first concentration interval, wherein the minimum concentration in the first concentration interval is greater than or equal to the first preset concentration, for example, the methane concentration belongs to a concentration interval of [5%, 15%].

[0072] That is, when it is detected that the concentration of the combustible gas in the internal air of the vehicle is too high, it is determined that the vehicle has a risk of spontaneous combustion, and at this time, a spontaneous combustion warning is performed.

[0073] 3. In the case that the vehicle temperature is in the second temperature range and the combustible gas concentration is in the second concentration range, the warning information is determined based on the target detection information.

[0074] For example, the vehicle temperature in the second temperature range means that the vehicle temperature is greater than or equal to a second preset temperature and the combustible gas concentration is greater than or equal to a second preset concentration. For example, the vehicle temperature is greater than or equal to 500 degrees and the methane concentration in the internal air of the vehicle is greater than or equal to 3%; or the vehicle temperature belongs to a second temperature interval and the methane concentration belongs to a second concentration interval, wherein the minimum temperature in the second temperature interval is greater than or equal to the second preset temperature, and the minimum concentration in the second concentration interval is greater than or equal to the second preset concentration, for example, the vehicle temperature is in a temperature interval of [500 degrees, 600 degrees] and the methane concentration is in a concentration interval of [3%, 15%].

[0075] That is, when it is detected that the internal temperature of the vehicle is too high and the concentration of the combustible gas in the internal air of the vehicle is too high, it is determined that the vehicle has a risk of spontaneous combustion, and at this time, a spontaneous combustion warning is performed.

[0076] In some embodiments, the warning information is determined based on the target detection information in a case that the combustible gas concentration is in the second concentration range and the vehicle temperature reaches a combustion point requirement of the combustible gas.

[0077] For example, the combustion point of methane is about 538 degrees Celsius, when the methane concentration in the air inside the vehicle is in the concentration interval of [3%, 15%] and the engine exhaust temperature is greater than or equal to 538 degrees, it is determined that the vehicle has a risk of spontaneous combustion, and a spontaneous combustion warning is performed at this time.

[0078] The warning information is used for spontaneous combustion warning of the vehicle in the target terminal and the vehicle, and the target terminal includes other terminals connected with the vehicle terminal.

[0079] For example, the warning information can be implemented as an indication information, which is used for indicating that the vehicle has a risk of spontaneous combustion, and when the vehicle or the target terminal obtains the warning information, corresponding spontaneous combustion warning can be performed according to the indication information.

[0080] Optionally, the target terminal can be a smart phone, a tablet computer, a computer, other vehicle terminals, and the like, which have a network connection function. For example, the target terminal can communicate with the vehicle terminal through a wireless network (such as 4G / 5G, Wi-Fi, etc.) or a wired connection (such as USB, Bluetooth, etc.).

[0081] Optionally, the preset warning condition is data pre-stored in the vehicle terminal of the vehicle, or the preset warning condition refers to data obtained from a server (for example, a cloud server).

[0082] In step 230, the vehicle is controlled to perform a first warning operation based on the warning information.

[0083] For example, after the warning information is determined, the vehicle obtains operation data corresponding to the first warning operation, which is pre-stored and matches the warning information. After the vehicle obtains the operation data, the vehicle is controlled to perform the first warning operation according to the operation data. Alternatively, after the warning information is determined, the warning information is sent to a server, the server determines operation data corresponding to the first warning operation according to the warning information and sends the operation data to the vehicle. After the vehicle obtains the operation data, the vehicle is controlled to perform the first warning operation according to the operation data.

[0084] Optionally, the method for controlling the vehicle to perform the first warning operation based on the warning information includes at least one of the following methods:

[0085] 1. Display a spontaneous combustion warning prompt based on the early warning information.

[0086] Optionally, the spontaneous combustion warning prompt can be implemented as a text prompt, an icon prompt, a color change prompt, and the like.

[0087] Illustratively, when the early warning information is acquired, it means that the vehicle has a risk of spontaneous combustion, at which time a spontaneous combustion early warning prompt can be displayed on the vehicle terminal. The spontaneous combustion early warning prompt can include a text prompt, such as "the vehicle has a risk of spontaneous combustion, please pay attention"; the vehicle spontaneous combustion prompt can also include an icon prompt, such as a flame, a thermometer overheat icon, etc., which will flicker or continuously light up on the vehicle terminal; the spontaneous combustion early warning prompt can also include a color change prompt, such as the screen background color of the vehicle terminal can gradually change to red or orange.

[0088] Optionally, the spontaneous combustion early warning prompt is also used to prompt the reason why the vehicle has a risk of spontaneous combustion.

[0089] Illustratively, when the early warning information is due to the vehicle temperature being too high, a temperature is too high prompt is displayed on the vehicle terminal, for example: a three-dimensional schematic diagram of the vehicle is displayed, which includes various components of the vehicle, and if the engine component is marked with a high temperature identifier, it means that the engine temperature of the vehicle is too high, and the vehicle has a risk of spontaneous combustion.

[0090] Or, when the early warning information is due to the combustible gas concentration being too high, a combustible gas concentration is too high prompt is displayed on the vehicle terminal, for example: a three-dimensional schematic diagram of the vehicle is displayed, and a combustible gas high concentration prompt is marked on the engine compartment of the schematic diagram, which means that the concentration of combustible gas in the engine compartment of the vehicle is too high, and the vehicle has a risk of spontaneous combustion.

[0091] 2. Control the vehicle to play a spontaneous combustion warning voice based on the early warning information.

[0092] Illustratively, the vehicle can emit an alarm sound, a buzzing sound or a voice prompt to warn that the current vehicle has a risk of spontaneous combustion.

[0093] 3. In the case where a target organism exists in the vehicle, control the steering wheel or seat to shake based on the early warning information. 4. Control the indicator light outside the vehicle to flash based on the early warning information.

[0094] Illustratively, when it is detected that there is a driver or passenger in the vehicle, the vehicle can control the steering wheel or seat in the vehicle to vibrate, thereby prompting the driver or passenger.

[0095] Figure 3

[0096] Illustratively, the indicator light of the roof or door of the vehicle can flicker to attract the attention of other vehicles or pedestrians.

[0097] It should be noted that the above examples of the first early warning operation are only illustrative, and the embodiments of the present application are not limited thereto.

[0098] Step 240, sending the early warning information to the target terminal.

[0099] Illustratively, if the target terminal communicates with the vehicle terminal through a wireless network, the vehicle terminal sends the early warning information to the server, and the server sends the early warning information to the target terminal; if the target terminal communicates with the vehicle through a wired network, the vehicle terminal directly sends the early warning information to the target terminal.

[0100] Optionally, the target terminal refers to a mobile terminal connected to the vehicle terminal, for example, the mobile terminal is a mobile phone of the owner of the vehicle. The target application program for controlling the vehicle is installed and run in the mobile terminal. Alternatively, the target terminal refers to another vehicle terminal connected to the vehicle terminal.

[0101] The early warning information is used to control the target terminal to perform a second early warning operation. Optionally, the second early warning operation includes at least one of the following cases:

[0102] 1. The early warning information is used to control the target terminal to display a spontaneous combustion early warning notification.

[0103] Optionally, the spontaneous combustion early warning notification includes a full-screen warning effect, a text early warning notification, an icon early warning notification, etc. The specific form of the spontaneous combustion early warning notification is not limited in the embodiments of the application.

[0104] Illustratively, when the mobile phone of the owner receives the early warning information, the spontaneous combustion early warning information can be displayed on the mobile phone of the owner in full screen, covering the currently running application program or interface, and notifying the owner that the current vehicle has a spontaneous combustion risk.

[0105] In some embodiments, the early warning information can further include the detected vehicle temperature and flammable gas concentration. Optionally, the spontaneous combustion early warning notification includes a vehicle abnormal state, and the vehicle abnormal state includes at least one of the vehicle temperature and the flammable gas concentration. Illustratively, the spontaneous combustion early warning notification displayed in the mobile phone of the owner can include the abnormal state data of the current vehicle, i.e., the vehicle temperature and / or the flammable gas concentration, so as to notify the owner of the reason for the spontaneous combustion early warning of the current vehicle.

[0106] In some embodiments, the early warning information can further include the current vehicle position. Optionally, the spontaneous combustion early warning notification includes vehicle position data. Illustratively, the spontaneous combustion early warning notification displayed in the mobile phone of the owner can include the vehicle position information, so as to enable the owner to quickly go to the location of the vehicle.

[0107] 2. The early warning information is used to control the target terminal to play a warning sound.

[0108] Illustratively, in addition to the visual warning by displaying the spontaneous combustion early warning notification, a sound warning can also be performed, such as controlling the mobile phone of the owner to play a high-decibel alarm sound or a voice prompt.

[0109] 3. The early warning information is used to control the target terminal to vibrate.

[0110] Illustratively, the owner can also be reminded by the vibration of the mobile phone, and the information is directly transmitted through the sense of touch to ensure that the owner can perceive the warning.

[0111] It should be noted that the above examples of the second early warning operation are only illustrative, and the embodiments of the present application do not limit this.

[0112] In some embodiments, before sending the early warning information to the target terminal, it is necessary to detect whether there is a passenger or driver in the current vehicle. If there is no one in the vehicle, the early warning information is sent to the target terminal.

[0113] Optionally, a motion sensor is installed in the vehicle; biological sensing data collected by the motion sensor is obtained; and in the case that the biological sensing data indicates that the target biological body does not exist in the vehicle, the early warning information is sent to the target terminal.

[0114] The motion sensor includes an infrared sensor, an ultrasonic sensor, a microwave sensor, a pressure-sensitive sensor, a millimeter sensor, etc., and the embodiments of the present application do not limit this.

[0115] Illustratively, the motion sensor can be installed at positions such as seats, steering wheels, and doors inside the vehicle. The motion sensor continuously monitors the motion of biological bodies inside the vehicle and collects related biological sensing data. When the biological sensing data collected by the motion sensor indicates that there is no one in the vehicle, the early warning information is sent to the target terminal, etc.

[0116] Optionally, a camera is installed in the vehicle, and a vehicle interior image collected by the camera is obtained; and in the case that the vehicle interior image indicates that the target biological body does not exist in the vehicle, the early warning information is sent to the target terminal.

[0117] Illustratively, the camera is installed inside the vehicle to ensure that it can cover positions such as the cockpit and passenger cabin. The camera collects images of the current vehicle interior in real time, and analyzes the collected images through image recognition technology. If the analysis result indicates that there is no one in the vehicle, the early warning information is sent to the target terminal, etc.

[0118] In the above embodiments, by detecting whether there is anyone in the vehicle, it can be ensured that the vehicle self-ignition early warning information is sent to the target terminal in time when there is no one inside the vehicle, so as to remind the owner or relevant personnel to take measures as soon as possible to avoid or reduce the vehicle self-ignition event that may be caused by the unattended vehicle. In addition, the early warning information is sent to the target terminal only when there is no one in the vehicle, which avoids frequent early warning information in the presence of people, thereby saving communication resources and avoiding waste of computer transmission resources caused by frequent data transmission.

[0119] In some embodiments, after sending the early warning information to the target terminal, the target terminal can be used to control the vehicle to perform the risk mitigation operation, so as to reduce the probability of the vehicle catching fire.

[0120] The risk mitigation operation includes, but is not limited to, starting an emergency cooling system, such as turning on the air conditioner, fan, opening the window, etc., to reduce the temperature inside the vehicle; activating the fire extinguishing system, if the vehicle is equipped with an automatic fire extinguishing system, the system can be activated to extinguish the fire at the initial stage of the fire to prevent the fire from spreading; unlocking the vehicle door, so that the vehicle can be entered in time for maintenance.

[0121] Optionally, the target terminal is used to determine the vehicle control instruction based on the early warning information, and the vehicle control instruction is used to control the vehicle to perform the risk mitigation operation; in the case where the vehicle control instruction sent by the target terminal is received, the vehicle is controlled to perform the risk mitigation operation.

[0122] Illustratively, when it is detected that there is no one in the vehicle, the vehicle sends early warning information to the owner's mobile phone, through which the owner can determine the vehicle control instruction for the vehicle; or, after receiving the early warning information, the target application program determines the vehicle control instruction according to the early warning information, such as: when the early warning information indicates that the temperature of the vehicle is too high, the target application program automatically determines the vehicle control instruction as starting the emergency cooling system, and the owner clicks to determine the vehicle control instruction.

[0123] Optionally, after the vehicle performs the risk mitigation operation, the execution result feedback is sent to the target terminal, which is used to inform the owner that the operation has been completed.

[0124] In the above embodiments, when it is detected that there is no one in the vehicle, the vehicle sends early warning information to the target terminal, and allows the target terminal to remotely perform the vehicle control operation to mitigate the risk of fire, thereby significantly reducing the probability of the vehicle catching fire.

[0125] In summary, the vehicle early warning method provided by the embodiments of the present application monitors the temperature and flammable gas concentration in the vehicle, and when it is detected that the temperature and / or flammable gas concentration of the vehicle meet the preset early warning condition, it indicates that the current vehicle has a risk of catching fire, at which time the vehicle is controlled to perform the corresponding early warning operation according to the generated early warning information, so as to issue an early warning when the risk of the vehicle catching fire increases, thereby reminding the personnel in the vehicle or other personnel (for example: passing pedestrians, etc.) to take timely measures to reduce the risk of the vehicle catching fire; in addition, the early warning information is also sent to other terminals connected to the vehicle terminal, and the other terminals are also controlled to perform the corresponding early warning operation, so as to expand the early warning range and ensure that the early warning information can be known by the relevant personnel (for example: users using the vehicle control application) in the case where the vehicle is unattended, so that the relevant personnel can respond more quickly to minimize the risk of the vehicle catching fire.

[0126] In some embodiments, the warning level can be determined according to the detected vehicle temperature and the combustible gas concentration, so as to give a self-ignition warning to the vehicle and the target terminal in a graded manner. Illustratively, as shown in FIG. 3, the self-ignition warning can be given to the vehicle and the target terminal in a graded manner according to the detected vehicle temperature and the combustible gas concentration. Figure 2 Figure 4 The embodiments shown in FIG. 3 can also be implemented as steps 310 to 340.

[0127] At step 310, target detection information corresponding to the vehicle is acquired.

[0128] The target detection information refers to detection information related to the self-ignition risk of the vehicle. The target detection information includes at least one of a vehicle temperature and a combustible gas concentration. The vehicle temperature is used to indicate the internal temperature of the vehicle, and the combustible gas concentration is used to indicate the concentration of combustible gas in the air inside the vehicle.

[0129] In some embodiments, the target detection information corresponding to the vehicle is acquired at a preset period. Illustratively, the vehicle temperature and the combustible gas concentration are acquired every 10 minutes, so as to determine whether the vehicle has a self-ignition risk.

[0130] At step 321, in a case where the target detection information meets a preset warning condition, a warning level is determined based on the target detection information.

[0131] The warning level is used to indicate the probability of the self-ignition event of the vehicle.

[0132] In some embodiments, the warning level includes a first-level warning, a second-level warning, and a third-level warning. The first-level warning indicates that the probability of the self-ignition event of the vehicle is less than the second-level warning, and the second-level warning indicates that the probability of the self-ignition event of the vehicle is less than the third-level warning.

[0133] Optionally, in a case where the vehicle temperature is within a first temperature range, the warning level is determined based on the vehicle temperature. Illustratively, when the vehicle temperature is greater than or equal to a first preset temperature, it is determined that the vehicle currently has a self-ignition risk, and the warning level can be determined according to the current vehicle temperature. If the difference between the vehicle temperature and the first preset temperature is less than or equal to a first temperature threshold, the warning level is the first-level warning; if the difference between the vehicle temperature and the first preset temperature is greater than the first temperature threshold and less than a second temperature threshold, the warning level is the second-level warning; and if the difference between the vehicle temperature and the first preset temperature is greater than or equal to a third temperature threshold, the warning level is the third-level warning.

[0134] ​Optionally, when the flammable gas concentration is within the first concentration range, the warning level is determined based on the flammable gas concentration. Illustratively, when the flammable gas concentration is greater than or equal to the first preset concentration, it is determined that the vehicle currently has the risk of spontaneous combustion, at which time the warning level can be determined according to the current flammable gas concentration. If the difference between the flammable gas concentration and the first preset concentration is less than or equal to the first concentration threshold, the warning level is a first-level warning; if the difference between the flammable gas concentration and the first preset concentration is greater than the first concentration threshold and less than the second concentration threshold, the warning level is a second-level warning; and if the difference between the flammable gas concentration and the first preset concentration is greater than or equal to the second concentration threshold, the warning level is a third-level warning.

[0135] Optionally, when the vehicle temperature is within the second temperature range and the flammable gas concentration is within the second concentration range, the warning level is determined based on the target detection information.

[0136] Illustratively, when the vehicle temperature is greater than or equal to the second preset temperature and the flammable gas concentration is greater than or equal to the second preset concentration, it is determined that the vehicle currently has the risk of spontaneous combustion, at which time a first candidate level can be determined according to the vehicle temperature and a second candidate level can be determined according to the flammable gas concentration.

[0137] If the difference between the vehicle temperature and the second preset temperature is less than or equal to the third temperature threshold, the first candidate level is a first-level warning; if the difference between the vehicle temperature and the second preset temperature is greater than the third temperature threshold and less than the fourth temperature threshold, the first candidate level is a second-level warning; and if the difference between the vehicle temperature and the second preset temperature is greater than or equal to the fourth temperature threshold, the first candidate level is a third-level warning. If the difference between the flammable gas concentration and the second preset concentration is less than or equal to the third concentration threshold, the second candidate level is a first-level warning; if the difference between the flammable gas concentration and the second preset concentration is greater than the third concentration threshold and less than the fourth concentration threshold, the second candidate level is a second-level warning; and if the difference between the flammable gas concentration and the second preset concentration is greater than or equal to the fourth concentration threshold, the second candidate level is a third-level warning.

[0138] Then, if the first candidate level and the second candidate level are different, the level higher between the first candidate level and the second candidate level is selected as the final warning level; for example, the first candidate level is a second-level warning and the second candidate level is a third-level warning, and the final warning level is a third-level warning. If the first candidate level and the second candidate level are the same, the first candidate level or the second candidate level is selected as the final warning level; for example, the first candidate level and the second candidate level are both third-level warnings, and the final warning level is a third-level warning.

[0139] Step 322, determining the warning information based on the warning level.

[0140] The early warning information is used for early warning of vehicle spontaneous combustion in the target terminal and the vehicle, the target terminal includes other terminals connected with the vehicle terminal of the vehicle, and the early warning information matches the early warning level.

[0141] According to the determined early warning level, the vehicle system generates corresponding early warning information.

[0142] Optionally, the first early warning information is generated when the early warning level is a first early warning, the second early warning information is generated when the early warning level is a second early warning, and the third early warning information is generated when the early warning level is a third early warning.

[0143] The first early warning information is used for first early warning of vehicle spontaneous combustion in the target terminal and the vehicle, the second early warning information is used for second early warning of vehicle spontaneous combustion in the target terminal and the vehicle, and the third early warning information is used for third early warning of vehicle spontaneous combustion in the target terminal and the vehicle.

[0144] The early warning information can be implemented as an indication information, which is used for indicating that the vehicle has a vehicle spontaneous combustion risk, wherein the first early warning of vehicle spontaneous combustion indicates that the vehicle spontaneous combustion risk is low, the second early warning of vehicle spontaneous combustion indicates that the vehicle spontaneous combustion risk is high, and the third early warning of vehicle spontaneous combustion indicates that the vehicle spontaneous combustion risk is extremely high. When the vehicle or the target terminal obtains the early warning information, corresponding early warning of vehicle spontaneous combustion can be performed according to the early warning information.

[0145] In step 330, the vehicle is controlled to perform a first early warning operation based on the early warning information.

[0146] The early warning information generated by different early warning levels controls different first early warning operations of the vehicle.

[0147] Taking displaying a spontaneous combustion early warning prompt based on the early warning information as an example, the early warning information generated by different early warning levels controls different spontaneous combustion early warning prompts displayed by the vehicle. Assuming that the spontaneous combustion early warning prompt is a text prompt, if the early warning level is a first early warning, the spontaneous combustion early warning prompt can be implemented as "prompt! Vehicle spontaneous combustion first early warning, the vehicle has a spontaneous combustion risk, and needs to be vigilant"; if the early warning level is a second early warning, the spontaneous combustion early warning prompt can be implemented as "attention! Vehicle spontaneous combustion second early warning, the vehicle has a high spontaneous combustion risk, please check the vehicle as soon as possible"; if the early warning level is a third early warning, the spontaneous combustion early warning prompt can be implemented as "emergency! Vehicle spontaneous combustion third early warning, the vehicle has a serious spontaneous combustion risk, please park immediately and keep away from the vehicle".

[0148] For example, based on the early warning information, the vehicle plays the spontaneous combustion early warning voice. The early warning information generated by different early warning levels controls the vehicle to play different spontaneous combustion early warning voice. For example, if the early warning level is level one early warning, the spontaneous combustion early warning voice plays the alarm sound with less playing times and normal volume; if the early warning level is level two early warning, the spontaneous combustion early warning voice plays the alarm sound with normal playing times and higher volume; if the early warning level is level three early warning, the spontaneous combustion early warning voice plays the alarm sound with more playing times and the highest volume.

[0149] For example, based on the early warning information, the vehicle controls the steering wheel or seat to vibrate. The early warning information generated by different early warning levels controls the steering wheel or seat to vibrate with different frequencies. For example, if the early warning level is level one early warning, the steering wheel or seat vibrates once; if the early warning level is level two early warning, the steering wheel or seat vibrates several times; if the early warning level is level three early warning, the steering wheel or seat vibrates strongly and lasts for several seconds.

[0150] For example, based on the early warning information, the vehicle controls the indicator light outside the vehicle to flash. The early warning information generated by different early warning levels controls the indicator light outside the vehicle to flash with different frequencies. For example, if the early warning level is level one early warning, the indicator light outside the vehicle is yellow and flashes slowly; if the early warning level is level two early warning, the indicator light outside the vehicle is yellow and flashes quickly; if the early warning level is level three early warning, the indicator light outside the vehicle is red and flashes with the highest frequency.

[0151] Step 340, send the early warning information to the target terminal.

[0152] Optionally, the target terminal refers to a mobile terminal connected with the vehicle terminal, for example, the mobile terminal is the mobile phone of the owner of the vehicle. The target application program for controlling the vehicle is installed and run in the mobile terminal. Alternatively, the target terminal refers to other vehicle terminals connected with the vehicle terminal.

[0153] The early warning information is used to control the target terminal to perform the second early warning operation.

[0154] For example, the early warning information generated by different early warning levels controls the target terminal to perform different second early warning operations.

[0155] For example, the early warning information is used to control the target terminal to display the spontaneous combustion early warning notification. The early warning information generated by different early warning levels controls the target terminal to display different spontaneous combustion early warning notifications. For example, if the early warning level is a first early warning, a text early warning notification "the vehicle has a spontaneous combustion risk, please pay attention" is displayed on the screen of the target terminal, and the screen has a slight background color change; if the early warning level is a second early warning, a text early warning notification "the vehicle spontaneous combustion risk is high, please check and take measures as soon as possible" is displayed on the screen of the target terminal, and the text early warning notification can have display effects such as increasing the font, changing the font color, and adding a flashing effect; if the early warning level is a third early warning, a text early warning notification "emergency! The vehicle has a serious spontaneous combustion risk" is displayed on the screen of the target terminal, and the text early warning notification can be full-screen displayed on the screen of the target terminal, and has a strong background color change and a flashing effect.

[0156] For example, the early warning information is used to control the target terminal to play the early warning sound. The early warning information generated by different early warning levels controls the target terminal to play different early warning sounds. For example, if the early warning level is a first early warning, a soft prompt sound is played, and the sound volume is normal; if the early warning level is a second early warning, a more urgent warning sound is played, and the sound volume is higher; if the early warning level is a third early warning, an emergency alarm sound is played, and the sound volume is the highest.

[0157] For example, the early warning information is used to control the target terminal to perform vibration prompting. The early warning information generated by different early warning levels controls the target terminal to vibrate at different frequencies. For example, if the early warning level is a first early warning, the owner's mobile phone vibrates once or twice; if the early warning level is a second early warning, the owner's mobile phone vibrates several times in succession; if the early warning level is a third early warning, the owner's mobile phone vibrates strongly and continuously.

[0158] In summary, the vehicle early warning method provided by the embodiments of the present application can determine different early warning levels according to the detected vehicle temperature and flammable gas concentration, thereby providing different levels of early warning information according to the size and urgency of the spontaneous combustion risk, enabling relevant personnel to more accurately understand the current spontaneous combustion risk situation through early warning by levels, thereby accurately responding to the early warning information, which helps to reduce the occurrence rate of vehicle spontaneous combustion accidents and reduce personnel casualties and property losses.

[0159] It should be noted that the early warning information in the embodiments of the present application can also be generated by the server, and then the vehicle temperature and flammable gas concentration collected by the vehicle are sent to the server for spontaneous combustion risk judgment by the server. For example, the server is implemented as a cloud server. Please refer to Figure 5 , which shows a principle schematic diagram of a vehicle early warning method provided by an example embodiment of the present application. The method includes the following steps:

[0160] 1. Start.

[0161] Illustratively, start the self-ignition risk detection process of the vehicle.

[0162] 2. Check Wi-Fi connection.

[0163] Illustratively, check the Wi-Fi connection of the vehicle's on-board system. If the connection is successful, it means that the on-board system can communicate wirelessly.

[0164] 3. If the Wi-Fi connection fails, reconnect.

[0165] Illustratively, if the Wi-Fi connection of the vehicle's on-board system fails, reattempt connection until it is successful. If the number of connection failures is greater than or equal to a first preset number, end the process.

[0166] 4. If the Wi-Fi connection is successful, check the cloud server connection.

[0167] Illustratively, if the Wi-Fi connection of the vehicle's on-board system is successful, check whether the on-board terminal can access the cloud server, i.e., whether it can communicate with the cloud server.

[0168] 5. If the cloud server connection fails, reconnect.

[0169] Illustratively, if the cloud server connection fails, reattempt connection until it is successful. If the number of connection failures is greater than or equal to a second preset number, end the process.

[0170] 6. If the cloud server connection is successful, the on-board terminal sends detection information to the cloud server.

[0171] Illustratively, if the cloud server connection is successful, the on-board terminal sends detection information to the cloud server. The detection information includes data collected by the in-vehicle engine temperature sensor and data collected by the gas sensor.

[0172] 7. The cloud server reads the temperature sensor and gas sensor values.

[0173] Illustratively, the cloud server reads the in-vehicle engine exhaust temperature detected by the in-vehicle engine temperature sensor and the concentration of flammable gas in the in-vehicle air detected by the gas sensor.

[0174] 8. The cloud server compares the read values with preset values.

[0175] Illustratively, the cloud server compares the in-vehicle engine exhaust temperature and the concentration of flammable gas in the in-vehicle air with preset values in the cloud server.

[0176] 9. If the read value is greater than or equal to the preset value, the car machine system gives a warning.

[0177] Illustratively, if the engine exhaust temperature in the vehicle is greater than or equal to a first preset temperature, the car machine system gives a warning; or if the concentration of flammable gas in the air in the vehicle is greater than or equal to a first preset concentration, the car machine system gives a warning; or if the concentration of flammable gas in the air in the vehicle is greater than or equal to a second preset concentration and the engine exhaust temperature in the vehicle is greater than or equal to the self-ignition temperature of the flammable gas, the car machine system gives a warning.

[0178] The car machine system giving a warning means that the vehicle-mounted terminal displays a red warning, and the vehicle-mounted terminal sends a warning message to a target terminal (such as a car owner's mobile phone, etc.), and the target terminal displays a self-ignition warning notification based on the warning message.

[0179] 10. If the read value is less than the preset value, the car machine system does not give a warning.

[0180] Illustratively, if the engine exhaust temperature in the vehicle is less than the first preset temperature and the concentration of flammable gas in the air in the vehicle is less than the first preset concentration, the car machine system does not give a warning; or if the engine exhaust temperature in the vehicle is less than the self-ignition temperature of the flammable gas, the car machine system does not give a warning.

[0181] The car machine system not giving a warning means that the vehicle-mounted terminal does not display a vehicle self-ignition warning prompt, and the vehicle-mounted terminal does not send a warning message to a target terminal (such as a car owner's mobile phone, etc.).

[0182] In some embodiments, in the case where the vehicle has a self-ignition risk, the vehicle-mounted terminal of the vehicle automatically sends a warning message to other vehicles in the vicinity, thereby also giving a self-ignition warning to other vehicles. Illustratively, as shown in Figure 2 or Figure 3 The embodiments shown in Figure 6 The embodiments shown in the above steps 510 to 543 can also be implemented as follows.

[0183] Step 510: Obtain target detection information corresponding to the vehicle.

[0184] The target detection information refers to detection information related to the self-ignition risk of the vehicle. The target detection information includes at least one of a vehicle temperature and a flammable gas concentration, the vehicle temperature being used to indicate the internal temperature of the vehicle, and the flammable gas concentration being used to indicate the concentration of flammable gas in the air inside the vehicle.

[0185] Step 520: In the case where the target detection information meets a preset warning condition, determine a warning message based on the target detection information.

[0186] The warning message is used to give a vehicle self-ignition warning in a target terminal and a vehicle, and the target terminal includes other terminals connected to the vehicle-mounted terminal of the vehicle.

[0187] Illustratively, the early warning information can include the current position of the vehicle, the current state (such as the temperature of the vehicle, the concentration of flammable gas, etc.), the early warning level, and the like.

[0188] Step 530, based on the early warning information, controlling the vehicle to perform a first early warning operation.

[0189] Illustratively, after obtaining the early warning information, the vehicle can be controlled to perform a first early warning operation, such as displaying a spontaneous combustion early warning prompt on the vehicle terminal, which can include a text prompt such as "the vehicle has a spontaneous combustion risk, please pay attention", and at the same time the vehicle can issue a warning sound, a buzzing sound or a voice prompt to warn that the current vehicle has a spontaneous combustion risk.

[0190] Step 541, sending a vehicle communication request to other vehicles.

[0191] The vehicle communication request is used to request communication with the vehicle terminal of other vehicles, and the distance between the target vehicle and the vehicle is less than or equal to a preset distance.

[0192] Illustratively, when the vehicle detects a spontaneous combustion risk, the vehicle will not only warn itself, but also try to establish communication with nearby vehicles to warn other vehicles. Optionally, the vehicle communication request is sent to other vehicles within a preset range, and the preset range is a circular range with the current position of the vehicle as the center and the preset distance as the radius.

[0193] Optionally, the vehicle communication request includes the identity information of the vehicle, the position information of the vehicle, and the like. Illustratively, the vehicle terminal broadcasts the vehicle communication request to other vehicles within the preset range through a wireless communication network.

[0194] Step 542, obtaining communication feedback information based on the vehicle communication request.

[0195] The communication feedback information includes the communication information of the target vehicle that successfully establishes a communication connection with the vehicle.

[0196] Optionally, the number of target vehicles can be one or more.

[0197] Illustratively, if vehicle A within the preset range receives the vehicle communication request and vehicle A agrees to establish a communication connection with vehicle B that generates a spontaneous combustion risk, vehicle A is the target vehicle, and vehicle A sends a response message to vehicle B, which includes the communication information of vehicle A, such as the identity information of the vehicle, the position information of the vehicle, and the like.

[0198] Step 543, based on the communication feedback information, sending early warning information to the vehicle terminal of the target vehicle.

[0199] The early warning information is used to control a vehicle terminal of the target vehicle to perform a second early warning operation.

[0200] Illustratively, the target vehicle successfully establishing the communication performs a corresponding operation according to the received early warning information, such as displaying an early warning notification on the vehicle terminal of the target vehicle, the vehicle terminal of the target vehicle sounding an alarm, and the like, to remind a driver or a passenger in the target vehicle that there is a vehicle with a spontaneous combustion risk nearby.

[0201] Please refer to Figure 7 which shows a schematic diagram of a vehicle early warning method. The vehicle 601 is a vehicle detected to have a spontaneous combustion risk. A flame early warning can be displayed on a vehicle terminal of the vehicle 601 to prompt personnel in the vehicle 601 that the current vehicle has a spontaneous combustion risk. Meanwhile, the vehicle 601 can also attempt to communicate with other vehicles nearby. If the vehicle 601 successfully establishes a communication connection with the vehicle 602, the vehicle 601 can send early warning information to the vehicle 602. The vehicle 602 displays a warning information according to the early warning information. The warning information is used to prompt personnel in the vehicle 602 that the vehicle 601 nearby has a spontaneous combustion risk.

[0202] Optionally, the vehicle or the target vehicle can be a vehicle in a stop state or a vehicle in a running state. If the vehicle and the target vehicle are vehicles in a running state, the target vehicle will also automatically increase a safety distance from the vehicle when the target vehicle receives the vehicle early warning information, to further improve safety.

[0203] In summary, the vehicle early warning method provided by the embodiments of the present application can automatically communicate with other vehicles when the vehicle has a spontaneous combustion risk. The early warning information can be quickly spread to vehicles nearby, so that more drivers can timely learn the spontaneous combustion risk information, thereby expanding the early warning range and improving the overall safety level.

In addition, the warning information is also sent to other terminals connected to the vehicle-mounted terminal, and the other terminals are also controlled to perform corresponding warning operations, thereby expanding the warning range and ensuring that the warning information can be known by relevant personnel (for example, users using a vehicle control application) in the case of no people in the vehicle, so that the relevant personnel can respond more quickly and minimize the risk of vehicle spontaneous combustion.
