[0045] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0046] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0047] In the related art, a residual liveness detection system is usually installed in the car, which issues an alarm when a live body is detected, thereby reducing the probability of such accidents. However, the current residual liveness detection system in the car still has the problem of a single alarm mode and unsatisfactory alarm effect.

[0048] In view of this, the embodiment of the present invention proposes an alarm method for leaving a living body in a vehicle, which is applied to the vehicle, referring to Figure 1 , Figure 1 FIG. 1 shows a flowchart of a method for alarming a living body left in a vehicle according to an embodiment of the present invention. Figure 1 As shown, the alarm method includes:

[0049] Step S101, when the target detection conditions are met, if a living body is detected in the car, a progressive alarm is executed, and the progressive alarm includes: executing multiple levels of alarms in order from low to high, wherein different levels of alarms correspond to different alarm information.

[0050] The target detection conditions include: the vehicle's power is off, the vehicle's doors (including the tailgate) and windows are closed, the vehicle's locks are locked, and the vehicle is not in motion. After the above target detection conditions are met, detection begins. If a living body is detected in the vehicle, such as an infant or a pet, a progressive alarm is executed.

[0051] Among them, a living body detection device can be set to detect whether there are living bodies left in the car. The specific living body detection device can be a controller with various radars or infrared sensors. In an embodiment of the present invention, in order to accurately detect whether there are living bodies left in the car, a controller with a millimeter wave radar is used to detect living bodies. After entering the detection, the millimeter wave radar will send a signal to the surroundings. If there are living bodies left in the car, the echo signal fed back by the living body will be received. The controller separates the breathing and heartbeat signals from the feedback echo signal, and obtains the frequency corresponding to the breathing and heartbeat signals. After the acquisition is completed, the breathing and heartbeat frequencies are matched with the breathing and heartbeat frequencies of adults. If the match is unsuccessful, it is determined that the living body is an infant or a pet. When the living body is determined to be an infant or a pet, a progressive alarm is performed.

[0052] In actual situations, there may be situations where the user gets off the car to buy supplies, and the purchase time is relatively short. In this case, the living things left in the car are not left by the user's negligence, so there is no need to execute a progressive alarm, or there is no need to execute a progressive alarm immediately. If a progressive alarm is executed immediately, the user experience will be greatly reduced. In order to avoid the above situation, in some optional implementations, a delayed alarm device can be additionally set, through which the user can select the default delayed alarm time, such as the default delayed alarm time is 90s, then the progressive alarm will be executed after 90s of detection; or the delayed alarm time can be set by the user, such as setting 10min, then the progressive alarm will be executed after 10min of detection.

[0053] Step S102: during the execution of the progressive alarm, if an event triggering satisfying the alarm end condition is detected, the progressive alarm is stopped.

[0054] Among them, the events that meet the alarm end condition include: the event that the vehicle door is switched from a closed state to an open state.

[0055] During the progressive alarm process, as long as the event of the vehicle door switching from closed to open is detected, the progressive alarm will stop. After the door is closed again, that is, the door switches from open to closed, and the vehicle's power mode switches from off to on, if the target detection conditions are met again, detection will be re-entered.

[0056] In addition, when the highest level of alarm is executed, it means that the progressive alarm has been executed for a long time. In order not to affect the user experience and to facilitate the user to stop the progressive alarm in time, additional events that meet the alarm end conditions can be added, such as the event that the vehicle power is switched from the off state to the on state, and the vehicle lock is switched from the locked state to the unlocked state. Alternatively, the user can also confirm to stop the progressive alarm remotely. For example, a voice call can be made to the user's mobile phone to inform the user that there is a living body left in the car. If the user confirms to stop the alarm, the progressive alarm will be stopped.

[0057] In an optional implementation, in the process of executing an alarm other than the highest level, the alarm method further includes:

[0058] If an event that meets the alarm suspension conditions is detected, the current level of alarm will be stopped;

[0059] When the alarm time of the next level of the current level arrives, the alarm of the next level is executed;

[0060] The event satisfying the alarm suspension condition includes: any one of an event in which the power of the vehicle is switched from an off state to an on state and an event in which the lock of the vehicle is switched from a locked state to an unlocked state.

[0061] In this embodiment, multiple levels of alarms including a first level alarm, a second level alarm, and a third level alarm are taken as an example. During the execution of a first level alarm or a second level alarm, if any one of the events of the vehicle power switching from an off state to an on state and the vehicle lock switching from a locked state to an unlocked state is detected, the execution of the first level alarm or the second level alarm is stopped, and when the alarm time of the next level of the current level arrives, the next level alarm is executed. For example, if the execution of the first level alarm is stopped, the second level alarm is executed when the second level alarm time arrives, or if the execution of the second level alarm is stopped, the third level alarm is executed when the third level alarm time arrives.

[0062] In addition, for alarms other than the lowest level and the highest level, users can also remotely confirm to stop the execution of the alarm at that level. For example, users can confirm whether to stop the progressive alarm through the APP. Specifically, still taking multiple levels of alarms including the first level alarm, the second level alarm and the third level alarm from low to high as an example, when executing the alarm other than the lowest level and the highest level, that is, during the execution of the second level alarm, the user can also confirm to stop the execution of the second level alarm through the APP.

[0063] In this way, when it is detected that there are living things left in the car, such as pets, even if the pet accidentally triggers an event that meets the alarm end conditions during the execution of an alarm other than the highest level, such as accidentally touching the vehicle power switch, causing the power to switch from the off state to the on state, the current level of alarm will be stopped, but the entire progressive alarm will not be stopped. When the alarm time of the next level of the current level arrives, the next level of alarm will be executed, and the alarm information will continue to be transmitted to the user, so as to avoid the situation where the alarm execution is accidentally stopped due to the living thing in the car, causing the user to not receive the alarm information in time, resulting in the living thing being suffocated.

[0064] In some optional implementations, the vehicle includes a living body detection device, and the alarm method further includes:

[0065] Detecting the working time of the living body detection device;

[0066] When it is detected that the working time exceeds the preset working time, the detection of living bodies in the vehicle is stopped and the working time is reset;

[0067] After stopping the detection of the living body in the vehicle, the alarm method further includes: stopping the execution of the progressive alarm.

[0068] The living body detection device may be a controller with various radars or infrared sensors. In the embodiment of the present invention, in order to accurately detect whether there is a living body left in the car, a controller with a millimeter wave radar is used to detect the living body, and when a living body is detected in the car, a progressive alarm is executed; after stopping the detection of the living body in the car, the progressive alarm is stopped.

[0069] At the same time, in order not to affect the user experience, the duration of the entire progressive alarm cannot exceed 60 minutes, that is, the working time of the liveness detection device cannot exceed 60 minutes. Therefore, in the embodiment of the present invention, the working time of the liveness detection device will also be detected. When the working time of the liveness detection device exceeds the preset working time, the detection of the live body in the car is stopped, that is, the progressive alarm is stopped. Among them, in order to ensure that the progressive alarm can be effectively executed, the preset working time is set to 30-60 minutes.

[0070] In an optional implementation, the multiple levels of alarms include a level 1 alarm, a level 2 alarm, and a level 3 alarm, and the multiple levels of alarms are executed in order from low to high alarm levels, including:

[0071] When executing the first level alarm, controlling the lights of the vehicle to flash and controlling the horn of the vehicle to honk, so as to output a first alarm message;

[0072] When executing the secondary alarm, controlling the lights of the vehicle to flash, controlling the horn of the vehicle to honk, and sending a reminder message to the target user terminal to output a second alarm message;

[0073] When executing the third level alarm, controlling the lights of the vehicle to flash, controlling the horn of the vehicle to honk, and sending a voice call to the target user terminal to output a third alarm message;

[0074] Among them, the level of the second-level alarm is higher than the level of the first-level alarm; the level of the third-level alarm is higher than the level of the second-level alarm.

[0075] Different alarm levels correspond to different alarm information outputs. The higher the alarm level, the richer the alarm information outputs, thereby progressively delivering alarm information to the user. Among them, the first alarm level is the lowest alarm level, and the first alarm information outputted by it is only: the vehicle lights flash and the vehicle horn honk.

[0076] The level of the second-level alarm is higher than that of the first-level alarm. If the second-level alarm is executed, it means that the living body has been left in the closed space of the car for a long time. To avoid the living body being suffocated, the user needs to be informed as soon as possible that there is a living body left in the car. Therefore, the second alarm information output corresponding to the second-level alarm not only includes the flashing of the vehicle lights and the honking of the vehicle horn, but also sends additional reminder information to the target user end. The target user end can be the user's mobile phone or an APP. For example, a text message is sent to the user's mobile phone to convey the alarm information to the user.

[0077] The third level alarm is the highest level alarm. If the third level alarm is executed, it means that the living body has been left in the closed space of the car for a long time. To avoid the living body from being suffocated, the user needs to be informed as soon as possible that there is a living body left in the car. Therefore, the third alarm information corresponding to the third level alarm output not only includes the flashing lights of the vehicle and the honking of the vehicle horn, but also sends a voice call to the target user end. The target user end can be the user's mobile phone. For example, a voice call is made to the user's mobile phone to convey the alarm information to the user. A voice call can be made to the user by setting up a seat call center.

[0078] In an optional implementation, the multiple levels of alarms are executed in order from low to high alarm levels, including:

[0079] When the level of the currently executed alarm is an alarm other than the lowest level alarm, the current alarm is executed multiple times, and a preset time interval is set between each two alarms.

[0080] In this embodiment, the lowest level alarm only needs to be executed once, and other levels of alarms can be executed multiple times, and a preset time interval is set between each two alarms. The preset time interval can be set to 30-60s.

[0081] Each level of alarm takes 30-60 seconds to execute, ensuring that the alarm information is delivered to the user in a timely manner.

[0082] In this embodiment, multiple levels of alarms include a first-level alarm, a second-level alarm, and a third-level alarm, that is, a first-level alarm is executed once, and a second-level alarm and a third-level alarm can be executed multiple times. Among them, for a second-level alarm, the corresponding output second alarm information also includes sending a reminder message to the target user end. In the specific implementation, to avoid affecting the user experience due to sending reminder messages too many times, it can be set to send reminder information to the target user end only once, or the user can set the number of times to send reminder messages by himself; for a third-level alarm, the corresponding output third alarm information also includes making a voice call to the target user end. In the specific implementation, to avoid affecting the user experience due to making voice calls too many times, it can be set to make a voice call to the target user end only once, or the user can set the number of times to make voice calls by himself.

[0083] In an optional implementation, the multiple levels of alarms are executed in order from low to high alarm levels, including:

[0084] When the alarm of the current level is executed, the interval length is determined according to the alarm of the current level and the alarm of the next level of the current level;

[0085] After the interval time, the next level of alarm of the current level is executed.

[0086] In this embodiment, multiple levels of alarms include level one alarm, level two alarm and level three alarm. When the level one alarm is executed, the interval between the level one alarm and the level two alarm is determined to be 90-150s, and the level two alarm is executed after an interval of 90-150s. When the level two alarm is executed, the interval between the level two alarm and the level three alarm is determined to be 3-5min, and the level three alarm is executed after an interval of 3-5min. During this period, if an event trigger that meets the alarm end condition is detected, the progressive alarm is stopped.

[0087] The embodiment of the present invention is provided with a progressive alarm including multiple levels. When a living body is detected left in the vehicle, the progressive alarm is executed, and different alarm information is output when executing different levels of alarms. The alarm information is transmitted in a timely manner and output more reasonably, thereby ensuring the safety of living bodies left in the vehicle while further improving the user experience.

[0088] Below, taking multiple levels of alarms including level 1 alarm, level 2 alarm and level 3 alarm as an example, the progressive alarm provided by the embodiment of the present invention is described:

[0089] Reference Figure 2 , Figure 2 FIG. 4 is a flow chart showing a method for alarming a living body left in a vehicle according to an embodiment of the present invention. Figure 2 As shown in the figure, the progressive alarm process is as follows:

[0090] If a living body is detected in the car, the first-level alarm will be executed. During the execution of the first-level alarm, if an event trigger that meets the alarm suspension condition is detected, the first-level alarm will be stopped, and the second-level alarm will be executed when the second-level alarm time arrives; if an event trigger that meets the alarm suspension condition is not detected, the first-level alarm will be executed after the first-level alarm is completed, and the second-level alarm will be executed when the second-level alarm time arrives; if an event trigger that meets the alarm end condition is detected, the progressive alarm will be stopped. During the execution of the second-level alarm, if an event trigger that meets the alarm end condition is detected, the progressive alarm will be stopped; if not detected, the second-level alarm will continue to be executed, and the third-level alarm will be executed when the third-level alarm time arrives. During the execution of the third-level alarm, if an event trigger that meets the alarm end condition is detected, the progressive alarm will be stopped; if not detected, the third-level alarm will continue to be executed until an event trigger that meets the alarm end condition is detected, or the working time of the living body detection device exceeds the preset working time, the progressive alarm will be stopped.

[0091] Among them, in the process of executing the second-level alarm (before the third-level alarm time arrives), there is the following situation: the living body in the car stops executing the alarm accidentally, such as accidentally touching the vehicle power switch, so that the power switches from the off state to the on state, the second-level alarm will stop executing. This may cause the user to be unable to receive the alarm information, or the reminder information sent to the target user end fails, and the user does not receive the alarm information. At this time, the living body may have been left in the car for a long time. If the alarm message is not continued to be delivered to the user, the risk of suffocation of the living body will increase. Based on this, if Figure 2 As shown, before the third-level alarm time arrives, it is necessary to detect whether an event that meets the alarm suspension condition is triggered. If the event trigger that meets the alarm suspension condition is not detected, the third-level alarm will be executed when the third-level alarm time arrives; if the event trigger that meets the alarm suspension condition is detected, the second-level alarm will be stopped. If the event trigger that meets the alarm end condition is not detected within 90-180s of the second-level alarm stopping execution, the second-level alarm will be executed after continuing to detect for 3-5 minutes; if the event trigger that meets the alarm end condition is detected, the progressive alarm will be stopped.

[0092] In addition, for the second-level alarm, during the execution of the second-level alarm, when the target user terminal confirms to stop the alarm, the execution of the progressive alarm can also be stopped, such as the user confirms to stop the alarm on the APP; for the third-level alarm, during the execution of the third-level alarm, if it is detected that any one of the events of the vehicle's power switching from the off state to the on state and the vehicle's lock switching from the locked state to the unlocked state is triggered, the execution of the progressive alarm can also be stopped, or, when the target user terminal confirms to stop the alarm, the execution of the progressive alarm can also be stopped, such as the user confirms to stop the alarm when answering a voice call.

[0093] Based on the same inventive concept, the embodiment of the present invention also provides an alarm device for leaving a living body in a car, referring to Figure 3 , Figure 3 FIG. 4 shows a module diagram of a device for warning a living body left in a vehicle according to an embodiment of the present invention. Figure 3 As shown, the alarm device comprises:

[0094] The alarm unit 301 is used to execute a progressive alarm if a living body is detected in the car when the target detection conditions are met. The progressive alarm includes: executing multiple levels of alarms in order from low to high, wherein different levels of alarms correspond to the output of different alarm information.

[0095] Among them, the target detection conditions include: the vehicle's power is off, the vehicle's doors and windows are closed, the vehicle's locks are locked, and the vehicle is not currently in motion. After the above target detection conditions are met, detection begins, and if a living body is detected in the vehicle, such as an infant or a pet, a progressive alarm is executed.

[0096] Among them, a living body detection device can be set in the alarm unit 301 to detect whether there is a living body left in the car. The specific living body detection device can be a controller with various radars or infrared sensors. In an embodiment of the present invention, in order to accurately detect whether there is a living body left in the car, a controller with a millimeter wave radar is used to detect the living body. After entering the detection, the millimeter wave radar will send a signal to the surroundings. If there is a living body left in the car, the echo signal fed back by the living body will be received. The controller separates the breathing and heartbeat signals from the feedback echo signal, and obtains the frequency corresponding to the breathing and heartbeat signals. After the acquisition is completed, the breathing and heartbeat frequencies are matched with the breathing and heartbeat frequencies of adults. If the match is unsuccessful, it is determined that the living body is an infant or a pet. When the living body is determined to be an infant or a pet, a progressive alarm is performed.

[0097] In actual situations, there may be situations where the user gets off the car to buy supplies, and the purchase time is relatively short. In this case, the living things left in the car are not left by the user's negligence, so there is no need to execute a progressive alarm, or there is no need to execute a progressive alarm immediately. If a progressive alarm is executed immediately, the user experience will be greatly reduced. In order to avoid the above situation, in some optional implementations, a delayed alarm device can be additionally provided in the alarm unit 301, through which the user can select the default delayed alarm time, such as the default delayed alarm time is 90s, then the progressive alarm will be executed after 90s of detection; or the delayed alarm time can be set by the user, such as setting it to 10min, then the progressive alarm will be executed after 10min of detection.

[0098] The detection unit 302 is used to stop executing the progressive alarm if an event triggering satisfying the alarm end condition is detected during the execution of the progressive alarm.

[0099] In an optional implementation, the event that satisfies the alarm end condition includes: an event in which a door of the vehicle switches from a closed state to an open state.

[0100] During the execution of the progressive alarm, as long as the detection unit 302 detects that the vehicle door switches from the closed state to the open state, the progressive alarm will be stopped. After the door is closed again, that is, the door switches from the open state to the closed state, and the power mode of the vehicle switches from the off state to the on state, if the target detection condition is met again, the detection will be re-entered.

[0101] In addition, when the highest level of alarm is executed, it means that the progressive alarm has been executed for a long time. In order not to affect the user experience and to facilitate the user to stop the progressive alarm in time, additional events that meet the alarm end conditions can be added, such as the event that the vehicle power is switched from the off state to the on state, and the vehicle lock is switched from the locked state to the unlocked state. Alternatively, the user can also confirm to stop the progressive alarm remotely. For example, a voice call can be made to the user's mobile phone to inform the user that there is a living body left in the car. If the user confirms to stop the alarm, the progressive alarm will be stopped.

[0102] In an optional embodiment, it further includes a detection subunit, which is used to stop executing the alarm of the current level if an event trigger that meets the alarm suspension condition is detected during the execution of the alarm except the highest level;

[0103] When the alarm time of the next level of the current level arrives, the alarm of the next level is executed;

[0104] The event satisfying the alarm suspension condition includes: any one of an event in which the power of the vehicle is switched from an off state to an on state and an event in which the lock of the vehicle is switched from a locked state to an unlocked state.

[0105] The embodiment of the present invention sets an alarm unit 301 and a detection unit 302, and when a living body is detected in the car, a progressive alarm is executed, wherein the progressive alarm includes multiple levels of progressive alarms, and different alarm information is output when executing different levels of alarms. During the execution of the progressive alarm, if the detection unit 302 detects an event trigger that satisfies the alarm end condition, the progressive alarm is stopped; if during the process of performing an alarm other than the highest level, the detection subunit detects an event trigger that satisfies the alarm suspension condition, the current level of alarm is stopped, and when the alarm time of the next level of the current level arrives, the next level of alarm is executed, so that the alarm information is transmitted in a timely manner and the alarm information is output more reasonably, so as to further improve the user experience while ensuring the safety of the living body left in the car.

[0106] Based on the same inventive concept, the embodiment of the present invention also provides an alarm system for leaving a living body in a car, referring to Figure 4 , Figure 4 FIG. 4 shows a schematic diagram of a structure of a vehicle-mounted living body alarm control system according to an embodiment of the present invention. Figure 4 As shown, the control alarm system includes: a living body detection device 1 and a vehicle body controller 2;

[0107] Among them, the living body detection device 1 is used to detect whether there is a living body left in the car when the target detection conditions are met. If a living body is detected in the car, an alarm signal is sent to the body controller 2, and the body controller 2 receives the alarm signal and outputs corresponding alarm information.

[0108] Among them, the alarm signal includes multiple levels of alarm signals, which are the first alarm signal, the second alarm signal and the third alarm signal in order from low to high. When the body controller 2 receives the above three alarm signals, it controls the vehicle's lights to flash and controls the vehicle's horn to honk to output alarm information. After the alarm signal output by the body controller 2, a corresponding feedback signal will be returned to notify the living body detection device 1 that the alarm information has been output.

[0109] like Figure 4 As shown, the living body detection device 1 is also connected to a gateway 3 , and the gateway 3 is connected to a background service 5 .

[0110] The liveness detection device 1 is also used to send alarm signals other than the lowest level alarm signal to the gateway 3. The gateway 3 receives the alarm signal and sends it to the background service 5. The background service 5 is used to output the corresponding alarm information to the target user terminal. The gateway 3 sends the alarm signal to the background service 5 through the vehicle-mounted wireless terminal 4. The liveness detection device 1 and the gateway 3, the gateway 3 and the vehicle-mounted wireless terminal 4, and the vehicle-mounted wireless terminal 4 and the background service 5 are all two-way communications.

[0111] The target user terminal can be the user's mobile phone or an APP. For example, a text message is sent to the user's mobile phone to convey the alarm information to the user, or a reminder message is pushed on the APP to convey the alarm information to the user, or a voice call is made to the user's mobile phone to convey the alarm information to the user. A seat call center can be set in the background service 5 to make a voice call to the user.

[0112] In addition, during specific implementation, the gateway 3 may also be connected to a multimedia host of the vehicle, so that the multimedia host can display the specific level and transmission status of the alarm signal.

[0113] Based on the same inventive concept, an embodiment of the present invention further provides a vehicle, which includes an alarm module, and the alarm module is used to implement the above-mentioned alarm method.

[0114] As for the device and system embodiments, since they are basically similar to the method embodiments, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiments.

[0115] It should be noted that the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0116] Although the preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the embodiments of the present invention.

[0117] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.

[0118] It should also be noted that, in this article, the orientation or position relationship indicated by the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. In addition, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that there is any such actual relationship or order between these entities or operations, nor can they be understood as indicating or implying relative importance. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or terminal device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such a process, method, article or terminal device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or terminal device including the elements.

[0119] The technical solution provided by the present invention is described in detail above. The principle and implementation mode of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the present invention, and the content of this specification should not be understood as limiting the present invention. At the same time, for those skilled in the art, according to the present invention, there will be different forms of changes in the specific implementation mode and application scope. It is not necessary and impossible to list all the implementation modes here, and the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
