Description

Technical Field

[0001] The present application relates to the technical field of vehicle environment monitoring, and particularly to a method, device and equipment for monitoring forgotten living bodies and foreign object intrusion in a vehicle. Background Art

[0002] When the vehicle owner parks and leaves, a child may be forgotten in the vehicle, causing a safety accident. In addition, after the vehicle owner parks and leaves, there may be foreign object intrusion into the vehicle, causing damage to the vehicle.

[0003] In some related technologies, a separate foreign object intrusion radar monitoring device and a child forgetting radar monitoring device are installed to monitor foreign object intrusion and forgotten children in the vehicle respectively, that is, the functions of reminding of forgotten children in the vehicle and alarming of foreign object intrusion are completed by using the radar monitoring device alone.

[0046] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0047] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0048] It can be understood that for the forgotten living body or foreign object intrusion in the vehicle, radar monitoring technology can be used to achieve monitoring and reminder to prevent accidents.

[0049] For example, the in-vehicle living body radar monitoring technology is set up to sense the situation inside the vehicle through a millimeter-wave radar and provide an alarm when necessary to avoid leaving a living body forgotten in the vehicle. The foreign object intrusion radar monitoring function senses whether there are new foreign objects inside the vehicle through the radar in the locked state and provides an alarm when necessary to ensure the safety of the vehicle.

[0050] In the present application, in order to solve the problems of high cost and complex in-vehicle wiring caused by separately monitoring the forgotten living body and foreign object intrusion through independent radar monitoring devices in the related art, in combination with the differences in usage scenarios, by distinguishing the effective time and monitoring accuracy, the same radar monitoring device is used to achieve the monitoring of both the forgotten living body and foreign object intrusion, avoiding the need to separately purchase and install radar monitoring devices with different functions, saving costs, and also reducing the power consumption of multiple radar monitoring devices on the vehicle battery.

[0051] That is, after the integrated design, there is no need to add additional wire harness connections for radar monitoring devices with different functions, simplifying the wiring of the vehicle electrical system, reducing the wire harness length and the number of connectors, reducing the wire harness cost, and improving the reliability of the vehicle system, reducing the number of failure points.

[0052] Figure 1 The figure shows a schematic diagram of the scenario architecture in the scenario of monitoring the forgotten living body and foreign object intrusion in the vehicle of the present application.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] In addition, the radar monitoring equipment can also communicate with the T-BOX in the vehicle.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] For another example, for the monitoring of external object intrusion, it is also possible to determine whether there is an external object intrusion according to the change amount of the radar monitoring distance generated after the external object intrusion and the relationship between the set distance threshold.

[0062] It can be understood that during the breathing process, the change amount of the distance is small, and the corresponding set distance threshold is small, such as 10 mm to 500 mm. That is, in this working state, the radar monitoring device requires higher monitoring accuracy (i.e., millimeter-level monitoring accuracy).

[0063] Correspondingly, since the intruding external object usually has a large volume, the resulting distance change is significant, and the corresponding set distance threshold is large, such as more than 10 cm. That is, in this working state, the radar monitoring device does not require high-precision monitoring, and the monitoring accuracy can be appropriately reduced, such as centimeter-level monitoring accuracy.

[0064] It can be understood that the radar monitoring device of the present application will consume a large amount of power from the vehicle battery when performing high-precision monitoring of the forgotten living body inside the vehicle. After completing the working stage of the forgotten living body inside the vehicle and entering the monitoring stage of external object intrusion, since it enters the low-precision monitoring working state, the working energy consumption is reduced, that is, the power consumption of the vehicle battery is reduced.

[0065] To better understand the method for monitoring the forgotten living body and external object intrusion in the vehicle provided by the present application, it will be described in detail below with reference to the accompanying drawings.

[0066] Figure 2 The following shows a schematic flowchart of the method for monitoring the forgotten living body and external object intrusion in the vehicle according to some embodiments of the present application.

[0067] This method can be executed by a radar monitoring device. As Figure 2 shown, this method specifically includes:

[0068] S110, receiving vehicle status information.

[0069] S120, when the vehicle status information indicates that the state of the vehicle changes from powered-on operation to powered-off parking, obtaining living body monitoring information in a first time period, where the living body monitoring information indicates whether there is a forgotten living body inside the vehicle.

[0070] S130, when the living body monitoring information indicates that there is a forgotten living body inside the vehicle, generating a forgotten living body reminder message for reminding the vehicle owner that there is a forgotten living body inside the vehicle.

[0071] S140, obtaining external object intrusion monitoring information in a second time period, where the external object intrusion monitoring information indicates whether there is an intruding object inside the vehicle, and the first time period is earlier than the second time period.

[0072] Specifically, during the use of the vehicle, it is determined that the radar monitoring device installed in the vehicle is in an on state, that is, it can communicate with the vehicle controller and the T-BOX, and receive vehicle status information in real time according to the set frequency.

[0073] The vehicle status information may include the operating status of each mechanism in the vehicle, such as being in a power-off parking state or a power-on operating state, as well as the locked or unlocked state of the vehicle, etc.

[0074] Further, when the radar monitoring device receives status information indicating that the vehicle has switched from a power-on operating state in the previous period to a power-off parking state, it first enters the forgotten living body monitoring working mode, that is, enters the first monitoring stage.

[0075] That is, the radar monitoring device obtains forgotten living body monitoring information in the first period, and the forgotten living body monitoring information can indicate whether there is a forgotten living body inside the vehicle. The forgotten living body monitoring information can be the distance information between various entities in the vehicle.

[0076] Further, the obtained forgotten living body monitoring information can be analyzed to determine whether there is a forgotten living body in the vehicle currently. When it is determined through analysis that the forgotten living body monitoring information obtained in the first period indicates that there is a forgotten living body in the vehicle currently, a forgotten living body prompt message can be generated to prompt the vehicle owner that there is a forgotten living body inside the vehicle by using the forgotten living body prompt message, that is, to remind the vehicle owner to take rescue actions.

[0077] Further, in the embodiment of the present application, after the radar monitoring device performs in-vehicle forgotten living body monitoring at the first time after the vehicle is powered off and parked, it 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.

[0078] 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 various entities inside the vehicle. Such as the distance between the rear seat and the front seat, etc., and the embodiment of the present application does not limit this.

[0079] In practice, the radar monitoring device can analyze the obtained foreign object intrusion monitoring information to determine whether there is a suspicious object in the vehicle, and when the foreign object intrusion monitoring information indicates that there is a suspicious object in the vehicle currently, a foreign object intrusion prompt operation can be performed to prompt the vehicle owner to take actions.

[0080] For example, when the external object intrusion monitoring information indicates that there is an intruder inside the vehicle, an external object intrusion prompt message can be generated to cause the vehicle to execute an alarm, such as honking and / or flashing lights, or the intrusion prompt message can also 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 vehicle owner's terminal device through a third-party server.

[0081] It can be understood that for the method for monitoring forgotten living bodies and external object intrusion in a vehicle according to the present application, through the radar monitoring device integrated with the functions of forgotten living bodies and external object intrusion set in the vehicle, after the vehicle is powered off and parked, it is possible to complete the monitoring of forgotten living bodies and external object intrusion in the vehicle based on different algorithms set in the radar monitoring device. That is, in the first monitoring stage after the vehicle is powered off and parked, the monitoring of forgotten living bodies inside the vehicle is carried out, and then when the monitored living body monitoring information indicates that there is a living body inside the vehicle, a reminder operation for the forgotten living body is performed on the vehicle owner; and then in the second monitoring stage, the monitoring of external object intrusion into the vehicle is carried out to obtain the external object intrusion monitoring information indicating whether there is an external object intrusion. The embodiments of the present application combine the differences in usage scenarios, distinguish the effective time, and use the same radar monitoring device to achieve the monitoring of two aspects of forgotten living bodies and external object intrusion, avoiding the problems of high cost caused by separately purchasing and installing a radar for monitoring forgotten living bodies and a radar for monitoring external object intrusion, and complex in-vehicle wiring, effectively saving the vehicle usage cost and improving the vehicle owner's usage experience.

[0082] In addition, the radar monitoring device in the embodiments of the present application sets different monitoring precisions and monitoring time periods for forgotten living bodies and intruding external objects according to the scene change characteristics of forgotten living bodies and intruding external objects inside the vehicle, so that in the monitoring of forgotten living bodies in the first monitoring stage, through the high-precision radar working state, the timely and accurate monitoring of forgotten living bodies is realized, and then in the monitoring of external object intrusion in the second monitoring stage, through the lower-precision working state, while realizing external object intrusion, the energy consumption of the storage battery is reduced.

[0083] Optionally, in some embodiments of the present application, during the monitoring of forgotten living bodies in the first monitoring stage, in order to effectively remind the vehicle owner, various reminder methods can be adopted to ensure the effectiveness of the reminder and ensure the life safety of the forgotten living body.

[0084] That is, in some embodiments, in order to ensure the effectiveness of the reminder and avoid accidents, during the monitoring stage of forgotten living bodies 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 effectively prompt the vehicle owner and not affect the normal execution of the subsequent working mode of external object intrusion monitoring in the vehicle.

[0085] When the vehicle owner cuts off the power and leaves for the first time, select a prompt message that directly acts on the vehicle to drive the vehicle to perform a reminder operation, such as directly and effectively reminding the vehicle owner by honking the horn or flashing the lights. And when the reminder in the first time period still fails to remind the vehicle owner to return, that is, the forgotten living body is still trapped in the vehicle, then in the subsequent time periods, select a reminder operation that directly acts on the mobile terminal carried by the vehicle owner. Specifically, the T-BOX and the vehicle network platform can be used to push the prompt message to the vehicle owner's mobile terminal through remote communication, so that the vehicle owner can discover in time and return to the vehicle to rescue the forgotten living body.

[0086] That is, as Figure 3 and Figure 4 shown, after obtaining the living body monitoring information, 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:

[0087] S121, when the living body monitoring information obtained in the first time period indicates that there is a forgotten living body currently, generate a first prompt message, and the first prompt message is used to instruct the prompt mechanism of the vehicle to perform a corresponding prompt operation.

[0088] S122, obtain the vehicle unlocking status information and the living body monitoring information in the third time period, and the third time period is earlier than the second time period and later than the first time period.

[0089] S123, when the vehicle unlocking status information indicates that the vehicle is not unlocked, and the living body monitoring information obtained in the third time period indicates that there is a forgotten living body currently, generate a second prompt message, and the second prompt message is used to make the third-party server push the forgotten living body prompt information to the vehicle owner's mobile terminal.

[0090] Specifically, as combined with Figure 4 shown, in practice, within the first time period after the vehicle is powered off and parked, such as within 1 minute after the vehicle is powered off and parked, when the vehicle owner has just left the vehicle and is still near the vehicle. During this time period, if it is detected that there is a forgotten living body in the vehicle, that is, when the living body monitoring information obtained in the first time period (such as within 10s after the vehicle is powered off and parked) indicates that there is a forgotten living body currently, 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 the horn and / or flash the lights, so that the vehicle owner can return to the vehicle in time and avoid accidents.

[0091] 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 lights and / or the horn, that is, honk the horn and / or flash the lights.

[0092] It can be understood that in some embodiments of the present application, after generating the first prompt message, for example, after 1 minute, the radar monitoring device continues to perform forgotten living body monitoring, that is, continuously obtains living body monitoring information to determine whether there is a living body signal, and after generating the first prompt message, continuously obtains the vehicle unlocking status through the T-BOX to determine whether the vehicle owner has returned.

[0093] As Figure 4 shown, if the vehicle unlocking status information obtained after the first time period indicates that it is open, it means that the vehicle owner has been successfully recalled through the first prompt message, and the vehicle owner has unlocked the vehicle to rescue the forgotten living body, then the working mode of the forgotten living body in this first monitoring stage ends, and the method can directly enter the second monitoring stage, that is, the foreign object intrusion monitoring stage.

[0094] That is, if the vehicle unlocking is detected, it is considered that the vehicle owner has taken measures to exit the living body forgetting monitoring function.

[0095] Furthermore, in the embodiments of the present application, when at the end of the first time period, for example, after 1 minute, the vehicle owner has not returned, 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 when the vehicle owner powers off and leaves, the living body monitoring information and vehicle unlocking status information monitored indicate that there is a forgotten living body, and the vehicle unlocking status information indicates that the vehicle has not been unlocked, it means that the vehicle owner has not returned and the forgotten living body in the vehicle still exists.

[0096] At this time, since the vehicle owner may have been far away from the vehicle, that is, the reminder methods of honking the horn and flashing the lights have failed, a second prompt message acting on the vehicle owner's mobile terminal can be generated.

[0097] That is, in the second time period, for example, after 1 minute, the generated second prompt message can be sent to the T-BOX through remote communication by using the T-BOX and the vehicle network platform, so that the T-BOX responds to the second prompt message and pushes the forgotten living body prompt information to the vehicle owner's mobile terminal through the third-party server, so that the vehicle owner can discover in time and return to the vehicle to rescue the forgotten living body.

[0098] It can be understood that in the embodiments of the present application, different reminder methods are selected according to the duration of the vehicle owner's power-off and parking, that is, the time when the vehicle owner leaves the vehicle, to ensure that the vehicle owner can receive the prompt message and the vehicle owner can be successfully recalled.

[0099] It can also be understood that as Figure 4 shown, in some embodiments of the present application, in order to ensure the normal start of the working mode in 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 can directly enter the second monitoring stage, that is, start to execute the foreign object intrusion algorithm.

[0100] Similarly, during the first monitoring stage, if the vehicle is detected to be unlocked and subsequent in-vehicle living body 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 system can directly enter the second monitoring stage, that is, start executing the algorithm for detecting external object intrusion. Additionally, when the configured time limit for the first monitoring stage expires and no unlocking operation has been detected, the system can also directly enter the second monitoring stage, that is, start executing the algorithm for detecting external object intrusion. That is, if the vehicle owner has not unlocked the vehicle, it is considered that the vehicle owner has not noticed the situation inside the vehicle. In this case, the system can continuously send text messages to the vehicle owner through the platform, exit the forgotten living body monitoring function, and enter the external object intrusion monitoring function.

[0101] For example, within the set 3 minutes, if the vehicle owner has been reminded through two reminder methods, then after 3 minutes, the system can directly enter the external object intrusion monitoring in the second monitoring stage according to the set working mode switching time.

[0102] At this time, in some embodiments, to ensure the safety of the forgotten living body, the first and second reminder methods can continue to be executed, such as continuously sounding the horn to attract the attention of passersby and continuously sending reminder messages to the vehicle owner's mobile terminal.

[0103] Optionally, in some embodiments of the present application, to ensure the safety of the forgotten living body trapped in the vehicle, when it is determined that there is a forgotten living body inside the vehicle, a vehicle environment adjustment mechanism can also be executed. That is, the method further includes:

[0104] S01, Obtain the vehicle unlocking status information in the fourth time period, which is earlier than the third time period.

[0105] S02, When the vehicle unlocking status information obtained in the fourth time period indicates that the vehicle is not unlocked, generate a control message.

[0106] S03, Send 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 vehicle internal environment.

[0107] Specifically, when it is detected in the first time period that there is a forgotten living body inside the vehicle, 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 each environment adjustment mechanism to act to adjust the vehicle internal environment.

[0108] For example, in response to the control message, the air conditioner can be controlled to turn on to adjust the temperature inside the vehicle so that the temperature inside the vehicle is within a comfortable range.

[0109] Alternatively, in response to the control message, the windows can also be controlled to open to achieve ventilation and air exchange inside the vehicle.

[0110] In practice, such as Figure 4As shown, in some embodiments, if the reminder in the first time period (e.g., within 1 minute) fails to effectively recall the vehicle owner, then the vehicle interior environment can be adjusted during the execution of the second time period (e.g., 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. If it indicates that no unlocking operation has occurred on the vehicle, then the interior environment adjustment mechanism is executed.

[0111] For example, one minute after the vehicle starts to alarm and the vehicle owner has not unlocked the vehicle, it is considered that the vehicle owner has not taken any measures.

[0112] At this time, it is possible to determine whether to turn on the air conditioner or slightly open the window for ventilation according to the temperature (e.g., 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 window for ventilation), so that the interior environment of the vehicle is within a better comfort range, ensuring the life safety of the forgotten living body.

[0113] It can be understood that in the working mode of the first monitoring stage in the embodiments of the present application, that is, in the stage of monitoring the forgotten living body, by obtaining in real time whether the vehicle is unlocked, it is determined whether the forgotten living body has been rescued. Furthermore, in the state where it has not been rescued, the vehicle is timely controlled to automatically power on, so as to timely adjust the vehicle interior environment through the air conditioner and / or the window, ensuring the safety of the living environment of the forgotten living body.

[0114] Optionally, in some embodiments of the present application, for the radar information indicating the distance between entities inside the vehicle monitored, specifically, the distance change amount can be compared with the set distance threshold to determine whether there is a forgotten living body and foreign object intrusion.

[0115] That is, in some embodiments of the present application, after obtaining the living body monitoring information, the method further includes:

[0116] 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 the set first distance threshold, it indicates that there is a forgotten living body inside the vehicle.

[0117] Specifically, during the actual monitoring process of the radar monitoring device, the collected monitoring information can be the monitoring distance, indicating the distance between each entity inside the vehicle.

[0118] In practice, when there is a forgotten living body inside the vehicle, due to the breathing action of the living body, the distance between the living body as an entity and the entities in the vehicle, such as the seat entity, will change. Then when the change amount of the monitoring distance meets the set first distance threshold (e.g., greater than 10 mm), it indicates that there is a forgotten living body inside the vehicle.

[0119] For example, generally, when children in a vehicle are sleeping, they are easily forgotten by the vehicle owner in the vehicle, such as children sleeping in the back row. For children in a deep sleep state, the breathing state causes the distance between the chest and abdomen and other entities inside the vehicle to change, and the change amount is greater than the set first distance threshold.

[0120] That is, when the radar monitoring device obtains the living body monitoring information, and the change amount of the monitoring distance in the living body monitoring information exceeds the first distance threshold, it indicates that there is a forgotten living body inside the vehicle in the current state.

[0121] Similarly, in some embodiments, for the analysis of the radar monitoring information of foreign object intrusion, it can also be realized by comparing the distance change amount and the set second distance threshold. That is, after obtaining the foreign object intrusion monitoring information, the method further includes:

[0122] Based on the foreign object intrusion monitoring information, determine the second change amount of the monitoring distance. When the second change amount is greater than the set second distance threshold, it indicates that there is an intrusion object inside the vehicle.

[0123] Specifically, based on the obtained foreign object intrusion monitoring information, determine the change amount of the current monitoring distance, that is, the second change amount. When the second change amount exceeds the set second distance threshold (such as greater than 10 cm), it indicates that there is a suspicious object inside the vehicle.

[0124] It can be understood that if there is a foreign object intrusion inside the vehicle, since the intrusion object is usually a large moving entity, such as a natural person, etc., the monitoring of the foreign object intrusion is also realized by monitoring the change amount of the distance of each entity in the vehicle. That is, continuously monitor the distances of all objects in all areas inside the vehicle through the radar, and monitor whether the distance changes greatly, such as greater than 10 cm. If the monitoring distance changes greatly, it indicates that there is a foreign object intrusion, and the whole vehicle immediately enters the alarm mode, and sends a prompt message, such as a text message, to the vehicle owner through the platform. This monitoring process can continue until the vehicle owner unlocks the vehicle.

[0125] In practice, in order to verify the power consumption of the battery by the radar monitoring device in different working states, the output current of the battery in different working states was measured.

[0126] Figure 5 Shown is a schematic circuit diagram of detecting the output current of the battery by the radar monitoring device in different working states. By measuring the vehicle current in different working states, that is, the output current of the battery, it can be determined that in the working state of monitoring the forgotten living body inside the vehicle, the output of the battery is 24 mA - 26 mA, while in the working state of monitoring foreign object intrusion in the vehicle, the output current of the battery is 13 mA - 15 mA.

[0127] It can be understood that through testing, it is further verified that by setting different working states and working stages, the power consumption of the storage battery can be effectively reduced.

[0128] 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, has a high power consumption in this stage, and the corresponding working time is short, and it cannot cause a large consumption of the electrical energy of the storage battery; while in the working state of vehicle external intrusion monitoring in the second time period, although the duration of this stage is long, due to its low working precision, the generated energy consumption is low, and it will not cause serious electrical energy consumption to the storage battery either.
