DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0021] It can be understood that radar monitoring technology can be used to monitor and warn of forgotten living beings or foreign objects invading the vehicle to prevent accidents.

[0022] For example, the in-car live radar monitoring technology uses millimeter-wave radar to sense the situation in the car and provide an alarm when necessary to prevent living people from being forgotten in the car. The foreign object intrusion radar monitoring function uses radar to sense whether there are new foreign objects in the car when the car is locked, and provides an alarm when necessary to ensure vehicle safety.

[0023] In this application, in order to solve the problems of high cost and complex wiring in the vehicle caused by using independent radar monitoring equipment to monitor forgotten living things and foreign objects intrusion respectively in the related technology, combined with the differences in usage scenarios, the same radar monitoring equipment is used to achieve monitoring of forgotten living things and foreign objects intrusion by distinguishing the effective time and monitoring accuracy, avoiding the need to separately purchase and install radar monitoring equipment with different functions, saving costs, and reducing the power consumption of the vehicle battery generated by multiple radar monitoring equipment.

[0024] That is, after the integrated design, there is no need to add additional wiring harness connections for radar monitoring equipment with different functions, which simplifies the wiring of the vehicle electrical system, reduces the wiring harness length and the number of connectors, reduces the wiring harness cost, and improves the reliability of the vehicle system and reduces failure points.

[0025] Figure 1 Shown is a schematic diagram of the scene architecture of the vehicle forgotten living body and foreign object intrusion monitoring scenario of the present application.

[0026] like Figure 1 As shown, in the scenario of foreign object intrusion monitoring and forgotten living body monitoring of the vehicle, the system may include a vehicle controller (ECU), an on-board communication unit (TelematicBOX, T-BOX), a vehicle network background system server and at least one radar monitoring device.

[0027] In some deployment scenarios, the system may include two radar monitoring devices, installed at the front and rear of the vehicle respectively. The radar monitoring devices at the front and rear of the vehicle can be used to monitor the front and rear seats of the vehicle respectively to determine whether there is living forgetfulness and foreign object intrusion.

[0028] In this system architecture, the radar monitoring device can be connected to the vehicle controller through the CAN bus communication to receive real-time vehicle operating status information, such as power-on operating status, power-off parking status and vehicle unlocking status.

[0029] In addition, the radar monitoring equipment can also communicate with the T-BOX in the vehicle.

[0030] It can be understood that the T-BOX in the vehicle is connected to the vehicle controller of the vehicle through the CAN bus, and can read various data of the vehicle, such as vehicle status, driving information, etc., and use wireless communication technology (such as 2G / 3G / 4G / wifi / Bluetooth, etc.) to exchange data with the owner's mobile terminal device, such as mobile phone APP, through the background system server, that is, the Internet of Vehicles platform, to achieve remote information reception, remote control, remote query of vehicle status and security services.

[0031] It can also be understood that in order to realize the monitoring of forgotten living beings and foreign objects intrusion in the vehicle, the radar monitoring device stores a data processing program and sets different threshold parameters, such as distance threshold, for different monitoring scenarios (i.e. forgotten living beings and foreign objects intrusion). The distance threshold is used as a judgment basis to determine whether there is a forgotten living being or foreign object intrusion.

[0032] That is, for the monitored radar information, the distance change can be analyzed to determine whether there is an abnormality, that is, whether there is a forgotten living body or foreign object intrusion. The radar information can be the distance between various entities inside the vehicle, such as the distance between the back seat and the front seat, etc., which is not limited in the embodiment of the present application.

[0033] For example, for forgotten living body monitoring inside a vehicle, such as a sleeping baby, the distance threshold in the corresponding radar monitoring process can be set according to the rise and fall of the chest during breathing, so that in actual monitoring, the change in the monitored distance is compared with the set distance threshold to determine whether there is a forgotten living body.

[0034] For another example, for monitoring of foreign object intrusion, it is also possible to determine whether there is foreign object intrusion based on the change in radar monitoring distance caused by the intrusion and the relationship between it and the set distance threshold.

[0035] It can be understood that due to the small distance change caused by breathing, the corresponding distance threshold is set to be small, such as 10mm~500mm. That is, in this working state, the radar monitoring equipment requires higher monitoring accuracy (i.e. millimeter-level monitoring accuracy).

[0036] Correspondingly, since the invading foreign objects usually have a large volume, the distance change caused is significant, and the corresponding distance threshold is set to be larger, such as above 10 cm. That is, in this working state, the radar monitoring equipment does not need high-precision monitoring, and the monitoring accuracy can be appropriately reduced, such as centimeter-level monitoring accuracy.

[0037] It can be understood that the radar monitoring equipment of the present application will consume a large amount of power on the vehicle battery when performing high-precision monitoring of forgotten living things inside the vehicle. After completing the working stage of forgotten living things inside the vehicle and entering the monitoring stage of foreign object intrusion, the radar monitoring equipment enters a low-precision monitoring working state, and the working energy consumption is reduced, that is, the power consumption of the vehicle battery is reduced.

[0038] In order to better understand the method for monitoring forgotten living beings and foreign objects intrusion in a vehicle provided by the present application, it is described in detail below with reference to the accompanying drawings.

[0039] Figure 2 Shown is a flow chart of a method for monitoring forgotten living beings and foreign objects intrusion in a vehicle according to some embodiments of the present application.

[0040] The method can be performed by radar monitoring equipment, such as Figure 2 As shown, the method specifically includes: S110, receiving vehicle status information.

[0041] S120, when the vehicle status information indicates that the vehicle status is switched from powered-on operation to powered-off parking, obtaining living body monitoring information in a first time period, the living body monitoring information indicating whether there is a forgotten living body in the vehicle.

[0042] S130: When the living body monitoring information indicates that a forgotten living body exists in the vehicle, a forgotten living body prompt message is generated, where the forgotten living body prompt message is used to prompt the vehicle owner that a forgotten living body exists in the vehicle.

[0043] S140, obtaining foreign object intrusion monitoring information in a second time period, the foreign object intrusion monitoring information indicating whether there is an intruder inside the vehicle, and the first time period is earlier than the second time period.

[0044] Specifically, during the use of the vehicle, it is determined that the radar monitoring device installed in the vehicle is in the on state, that is, it can communicate with the vehicle controller and T-BOX, and receive vehicle status information in real time according to the set frequency.

[0045] The vehicle status information may include the operating status of each mechanism in the vehicle, such as whether the vehicle is in a power-off parking state or a power-on running state, and whether the vehicle is locked or unlocked.

[0046] Furthermore, when the radar monitoring device receives status information indicating that the vehicle has switched from the powered-on state in the previous period to the powered-off parking state, the forgotten living body monitoring working mode is first performed, that is, the first monitoring stage is entered.

[0047] That is, the radar monitoring device obtains the living body monitoring information in the first period, and the living body monitoring information can indicate whether there is a forgotten living body in the vehicle. The living body monitoring information can be the distance information between each entity in the vehicle.

[0048] Furthermore, the acquired living body monitoring information can be analyzed to determine whether there is a forgotten living body in the vehicle. When it is determined through analysis that the living body monitoring information acquired in the first period indicates that there is a forgotten living body in the vehicle, a forgotten living body prompt message can be generated to use the forgotten living body prompt message to prompt the owner that there is a forgotten living body in the vehicle, that is, to remind the owner to take rescue actions.

[0049] Furthermore, in an embodiment of the present application, the radar monitoring device performs forgotten living body monitoring in the vehicle as soon as the vehicle is powered off and parked, and then enters the second stage of monitoring, that is, after the radar monitoring device monitors the forgotten living body in the vehicle, the radar monitoring device performs foreign object intrusion monitoring.

[0050] That is, the radar monitoring device obtains foreign object intrusion monitoring information in the second period after the first period, and the foreign object intrusion monitoring information indicates whether there is a suspicious object outside the vehicle. The foreign object intrusion monitoring information can also be the distance between entities inside the vehicle, such as the distance between the back seat and the front seat, etc., which is not limited in the embodiment of the present application.

[0051] In practice, the radar monitoring device can analyze the acquired foreign object intrusion monitoring information to determine whether there are any suspicious objects in the vehicle, and when the foreign object intrusion monitoring information indicates that there are suspicious objects in the current vehicle, a foreign object intrusion prompt operation can be performed to prompt the owner to take action.

[0052] For example, when the foreign object intrusion monitoring information indicates that there is an intruder inside the vehicle, a foreign object intrusion prompt message can be generated to cause the vehicle to execute an alarm, such as honking the horn and / or flashing the lights, or the intrusion prompt message can be sent to the T-BOX, so that the T-BOX responds to the intrusion prompt message and pushes the suspicious object intrusion to the owner's terminal device through a third-party server.

[0053] It can be understood that the method for monitoring forgotten living beings and foreign objects in the vehicle of the present application, through the radar monitoring device with integrated functions of forgotten living beings and foreign objects intrusion set in the vehicle, can complete the monitoring of forgotten living beings and foreign objects intrusion in the vehicle based on different algorithms set in the radar monitoring device after the vehicle is powered off and parked, that is, in the first monitoring stage after the vehicle is powered off and parked, the monitoring of forgotten living beings in the vehicle is carried out, and then when the monitored living beings monitoring information indicates that there is a living being in the vehicle, the owner is prompted to forget the living being; and then in the second monitoring stage, the vehicle is monitored for foreign objects intrusion to obtain foreign objects intrusion monitoring information indicating whether there is foreign objects intrusion. The embodiment of the present application combines the differences in usage scenarios, distinguishes the effective time, and uses the same radar monitoring device to realize the monitoring of forgotten living beings and foreign objects intrusion, avoiding the high cost and complex wiring in the vehicle caused by the separate purchase and installation of forgotten living beings monitoring radar and foreign objects intrusion monitoring radar, effectively saving the cost of vehicle use and improving the owner's experience.

[0054] In addition, the radar monitoring equipment in the embodiment of the present application sets different monitoring accuracies and monitoring time periods for forgotten living beings and invading foreign objects according to the scene change characteristics of forgotten living beings and invading foreign objects inside the vehicle, so that in the first monitoring stage of forgotten living being monitoring, the high-precision radar working state can be used to achieve timely and accurate monitoring of forgotten living beings, and then in the second monitoring stage of foreign object intrusion monitoring, a lower-precision working state can be used to achieve foreign object intrusion while reducing the energy consumption of the battery.

[0055] Optionally, in some embodiments of the present application, during the forgotten living body monitoring process in the first monitoring phase, in order to effectively remind the car owner, multiple reminder methods can be used to ensure the effectiveness of the reminder and protect the life safety of the forgotten living body.

[0056] That is, in some embodiments, in order to ensure the effectiveness of reminders and avoid accidents, during the stage of forgotten living body monitoring in the vehicle, different reminder methods can be further executed in stages according to the time when the vehicle is powered off and parked, so as to ensure that the owner is effectively reminded and does not affect the normal execution of the subsequent vehicle foreign object intrusion monitoring working mode.

[0057] For example, when the owner loses power and leaves, a prompt message is selected to act directly on the vehicle to drive the vehicle to perform a reminder operation, such as directly and effectively reminding the owner by honking or flashing lights. If the reminder in the first time period still fails to remind the owner to return, that is, the forgotten living body is still trapped in the vehicle, then in the subsequent time period, a reminder operation is selected to act directly on the mobile terminal carried by the owner. Specifically, the prompt message can be pushed to the owner's mobile terminal through remote communication using T-BOX and the vehicle network platform, so that the owner can find it in time and return to the vehicle to rescue the forgotten living body.

[0058] That is Figure 3 and Figure 4 As shown, after the living body monitoring information is obtained, and the living body monitoring information indicates that there is a living body in the vehicle, a prompt message is generated, which may specifically include: S121, when the living body monitoring information acquired in the first time period indicates that a forgotten living body currently exists, a first prompt message is generated, where the first prompt message is used to instruct a prompt mechanism of the vehicle to perform a corresponding prompt operation.

[0059] S122, obtaining vehicle unlocking state information and living body monitoring information in a third time period, where the third time period is earlier than the second time period and later than the first time period.

[0060] S123, when the vehicle unlocking status information indicates that the vehicle is not unlocked, and the liveness monitoring information obtained in the third period indicates that a forgotten liveness exists, a second prompt message is generated, and the second prompt message is used to enable the third-party server to push a forgotten liveness prompt message to the mobile terminal of the vehicle owner.

[0061] Specifically, combined Figure 4 As shown, in practice, within the first time period of the vehicle being powered off and parked, such as within 1 minute of being powered off and parked, the owner is still near the vehicle when he or she just leaves the vehicle. During this time period, if a forgotten living body is detected in the vehicle, that is, the living body monitoring information obtained in the first time period (such as within 10 seconds of being powered off and parked) indicates that a forgotten living body currently exists, a first prompt message acting on the vehicle can be generated to instruct the vehicle to directly perform a prompt operation, such as controlling the vehicle to honk and / or flash the lights, so that the owner can return to the vehicle in time to avoid accidents.

[0062] For example, in some embodiments, after the radar monitoring device generates the first prompt message, it can send the first prompt message to the vehicle controller, so that the vehicle controller responds to the first prompt message and controls the operation of the vehicle lights and / or horn, that is, honking the horn and / or flashing the lights.

[0063] It can be understood that in some embodiments of the present application, after the first prompt message is generated, such as after 1 minute, the radar monitoring device continues to perform forgotten liveness monitoring, that is, continues to obtain liveness monitoring information to determine whether there is a liveness signal, and after generating the first prompt message, continues to obtain the vehicle unlocking status through T-BOX to determine whether the owner has returned.

[0064] like Figure 4 As shown, if the vehicle unlocking status information obtained after the first time period indicates that it is turned on, it means that the car owner is successfully called back through the first prompt message, and the car owner rescues the forgotten living body by unlocking the vehicle, then the working mode of the forgotten living body in the first monitoring stage ends, and the method can directly enter the second monitoring stage, that is, the foreign object intrusion monitoring stage.

[0065] That is, if the vehicle is detected to be unlocked, it is considered that the owner has taken measures to exit the live forgetting monitoring function.

[0066] Furthermore, in an embodiment of the present application, when the vehicle owner has not returned at the end of the first time period, such as after 1 minute, that is, at the end of the first time period, that is, the third time period after the first time period, such as the third minute after the vehicle owner has left the vehicle without power, the monitored living body monitoring information and vehicle unlocking status information indicate that a forgotten living body exists, and when the vehicle unlocking status information indicates that no unlocking operation has occurred on the vehicle, it means that the vehicle owner has not returned and the forgotten living body still exists in the vehicle.

[0067] At this time, since the owner may have moved away from the vehicle, that is, the reminder methods of honking the horn and flashing the lights have become invalid, a second reminder message can be generated for the owner's mobile terminal.

[0068] That is, in the second time period, such as 1 minute later, the T-BOX and the vehicle network platform can be used to send the generated second prompt message to the T-BOX through remote communication, so that the T-BOX responds to the second prompt message and pushes the forgotten living body prompt information to the car owner's mobile terminal through the third-party server, so that the car owner can find it in time and return to the vehicle to rescue the forgotten living body.

[0069] It can be understood that in the embodiment of the present application, different reminder methods are selected according to the duration of the owner's power-off parking, that is, the time when the owner leaves the vehicle, to ensure that the owner can receive the reminder message and successfully call the owner back.

[0070] It is also understandable that Figure 4 As shown, in some embodiments of the present application, in order to ensure the normal start of the working mode of the second monitoring stage, when the living body monitoring information monitored in the first time period of the first monitoring stage indicates that there is no forgotten living body at present, it is possible to directly enter the second monitoring stage, that is, start executing the foreign object intrusion algorithm.

[0071] Similarly, if the vehicle is detected to be unlocked in the first monitoring stage, and the subsequent liveness monitoring information indicates that there is no forgotten living body inside the vehicle, it means that the forgotten living body has been successfully rescued, and the second monitoring stage can also be directly entered, that is, the algorithm for foreign object intrusion is started. In addition, when the configured first monitoring stage time expires, if the unlocking operation is still not detected, the second monitoring stage can also be directly entered, that is, the algorithm for foreign object intrusion is started. That is, if the owner has not unlocked the vehicle, it is considered that the owner has not discovered the situation inside the car. The platform can continue to send text messages to the owner, and exit the forgotten liveness monitoring function and enter the foreign object intrusion monitoring function.

[0072] For example, within the set 3 minutes, the car owner is reminded through two reminder methods. After 3 minutes, the working mode switching time can be switched according to the set working mode, and the second monitoring stage of foreign object intrusion monitoring can be directly entered.

[0073] At this time, in some embodiments, in order to ensure the life safety of the forgotten living being, the first and second reminder methods can continue to be executed, such as by continuously honking the horn to attract the attention of passers-by, and by continuously sending reminder information to the owner's mobile terminal.

[0074] Optionally, in some embodiments of the present application, in order to ensure the life safety of the forgotten living body trapped in the vehicle, when it is determined that there is a forgotten living body in the vehicle, a vehicle environment adjustment mechanism may also be executed, that is, the method further includes: S01, obtaining vehicle unlocking status information in a fourth time period, where the fourth time period is earlier than the third time period.

[0075] S02: When the vehicle unlocking status information obtained during the fourth period indicates that the vehicle is not unlocked, a control message is generated.

[0076] S03, sending the control message to the vehicle controller, so that the vehicle controller responds to the control message and controls the environment control mechanism to adjust the internal environment of the vehicle.

[0077] Specifically, when the presence of a forgotten living body is detected in the vehicle during the first period, the radar monitoring device can generate a control message and send it to the vehicle controller, so that the vehicle controller responds to the control message and controls the operation of each environmental adjustment mechanism to adjust the environment inside the vehicle.

[0078] For example, in response to the control message, the air conditioner can be controlled to turn on, and the temperature inside the vehicle can be adjusted so that the temperature inside the vehicle is within a comfortable range.

[0079] Alternatively, in response to the control message, the vehicle windows may be controlled to open to achieve ventilation inside the vehicle.

[0080] In practice, if Figure 4 As shown, in some embodiments, if the reminder in the first time period (such as within 1 minute) cannot effectively recall the vehicle owner, the vehicle's internal environment can be adjusted during the second time period (such as the reminder after 1 minute), that is, in the fourth time period after the first time period and before the third time period, the vehicle unlocking status information is obtained, and if it indicates that the vehicle has not been unlocked, the internal environment adjustment mechanism is executed.

[0081] For example, if the vehicle starts to alarm for one minute and the owner does not unlock the vehicle, it is considered that the owner has not taken any action.

[0082] At this time, you can determine whether to turn on the air conditioner or slightly open the windows for ventilation based on the temperature (for example, when the temperature is greater than 25 degrees and less than 15 degrees, turn on the air conditioner, or turn on the air conditioner and slightly open the windows for ventilation), so that the environment inside the vehicle is within a comfortable range and ensure the life safety of the forgotten living being.

[0083] It can be understood that in the embodiment of the present application, in the working mode of the first monitoring stage, that is, in the forgotten living body monitoring stage, whether the vehicle is unlocked is obtained in real time to determine whether the forgotten living body is rescued, and then in the unrescued state, the vehicle is controlled to automatically power on in time, so as to adjust the internal environment of the vehicle in time through the air conditioning and / or windows to ensure the safety of the living environment of the forgotten living body.

[0084] Optionally, in some embodiments of the present application, the monitored radar information representing the distance between entities in the vehicle can be compared with a set distance threshold to determine whether there is an intrusion of forgotten living beings and foreign objects.

[0085] That is, in some embodiments of the present application, after obtaining the living body monitoring information, the method further includes: Based on the living body monitoring information, a first change amount of the monitoring distance is determined. When the first change amount is greater than a set first distance threshold, it indicates that a forgotten living body exists inside the vehicle.

[0086] Specifically, during the actual monitoring process, the monitoring information collected by the radar monitoring device may be a monitoring distance, which indicates the distance between entities inside the vehicle.

[0087] In practice, when there is a forgotten living body in the vehicle, the distance between the living body as an entity and the entity in the vehicle, such as the seat entity, will change due to the breathing action of the living body. When the change in the monitoring distance meets the set first distance threshold (such as greater than 10mm), it means that there is a forgotten living body in the vehicle.

[0088] For example, in general, children in a vehicle are easily forgotten by the owner when they are sleeping, such as children sleeping in the back seat. The breathing state of a sleeping child causes the distance between the chest and abdomen and other entities in the vehicle to change, and the change is greater than the set first distance threshold.

[0089] That is, when the radar monitoring device obtains the living body monitoring information, and the change in the monitoring distance in the living body monitoring information exceeds the first distance threshold, it indicates that in the current state, there is a forgotten living body in the vehicle.

[0090] Similarly, in some embodiments, the analysis of the radar monitoring information of foreign object intrusion can also be achieved by comparing the distance change amount with the set second distance threshold, that is, after obtaining the foreign object intrusion monitoring information, the method further includes: Based on the foreign object intrusion monitoring information, a second change in the monitoring distance is determined. When the second change is greater than a set second distance threshold, it indicates that there is an intruder inside the vehicle.

[0091] Specifically, based on the acquired foreign object intrusion monitoring information, the change amount of the current monitoring distance, that is, the second change amount, is determined. When the second change amount exceeds the set second distance threshold (such as greater than 10 cm), it indicates that a suspicious object has appeared inside the vehicle.

[0092] It can be understood that if there is a foreign object intrusion inside the vehicle, since the intruder is usually a large mobile entity, such as a natural person, the monitoring of the foreign object intrusion is also achieved by monitoring the change in the distance of entities in various areas of the vehicle. That is, the distance of each object in all areas of the vehicle is continuously monitored by radar, and whether the distance changes on a large scale, such as greater than 10cm. If the monitoring distance changes on a large scale, indicating that there is a foreign object intrusion, the entire vehicle immediately enters the alarm mode and sends a prompt message to the owner through the platform, such as a text message. The monitoring process can continue until the owner unlocks the vehicle.

[0093] In practice, in order to verify the power consumption of the battery by the radar monitoring equipment under different working conditions, the output current of the battery under different working conditions was measured.

[0094] Figure 5 The figure shows a circuit structure diagram of the radar monitoring equipment for detecting the battery output current under different working conditions. By measuring the vehicle current under different working conditions, that is, the battery output current, it can be determined that in the forgotten living body monitoring working state inside the vehicle, the battery output is 24 mA ~ 26mA, and in the vehicle foreign object intrusion monitoring working state, the battery output current is 13 mA ~ 15 mA.

[0095] It can be understood that the test further verifies that by setting different working states and working stages, the power consumption of the battery can be effectively reduced.

[0096] That is, the working state in the first time period after the vehicle is powered off, that is, the high-precision forgotten living body monitoring state. The power consumption in this stage is relatively high, and the corresponding working time is short, which cannot cause a large consumption of the battery's power; and in the working state of the vehicle's foreign object intrusion monitoring in the second time period, although the duration of this stage is longer, due to its low working accuracy, the energy consumption generated is low, and it will not cause serious power consumption to the battery.
