[0073] In order to illustrate the technical solutions of the disclosure, the following will be described by specific embodiments.

[0074] The life body left detection method provided by the embodiments of the disclosure can be applied to a life body left detection system as shown in FIG. 1, which includes a vehicle and a life body left detection device. The life body left detection device communicates with the vehicle through a bus or a network.

[0075] The life body left detection device judges the whole vehicle state of the vehicle, and when it is determined that the vehicle meets the preset detection condition, the life body left detection device wakes up the preset detection device inside the vehicle, and performs joint detection of the life body inside the vehicle by optical and mechanical waves, wherein the preset detection condition includes that the vehicle is in an off state, the vehicle is not in a transportation mode and a fast silent mode, the vehicle door state is detected from open to closed, and finally all the vehicle doors are closed; when it is detected that there is a target life body inside the vehicle, the vehicle is controlled to perform life body left reminding. First, the whole vehicle state is judged, and when the whole vehicle state meets the off state, the non-transportation mode and the fast silent mode, the vehicle door state is changed from open to closed, and finally all the vehicle doors are closed, the life body inside the vehicle is detected, which can avoid detection in some unnecessary cases, reduce false detection, and also perform joint detection of the life body inside the vehicle by optical and mechanical waves through the preset detection device inside the vehicle, further reducing the false detection and missing detection, improving the accuracy of life body detection and timely reminding the relevant personnel, and thus improving the user experience of using the vehicle.

[0076] In the present disclosure, the living body left detection system includes a vehicle and a living body left detection device, and in other embodiments, the living body left detection system also includes other devices, such as a preset detection device installed inside the vehicle. For example, the preset detection device can include a camera and a millimeter wave radar inside the vehicle.

[0077] The living body left detection device can be a controller on the vehicle, such as a vehicle controller or a body domain controller. In other embodiments, the living body left detection device can also be a device independent of the vehicle, such as a cloud server.

[0078] In an embodiment, the living body left detection system can include a vehicle, and a living body left detection device, a preset detection device, and various modules for living body left reminding or communication on the vehicle. As shown in FIG. 2, the living body left detection system can include a vehicle (not shown), a living body left detection device (a body domain controller), a preset detection device (including an in-vehicle camera 1, an in-vehicle camera 2, a millimeter wave radar 1, and a millimeter wave radar 2), a multimedia domain controller (a vehicle-mounted multimedia audio system), a gateway control module, a left detection function related module, and a remote information prompting module. The remote information prompting module includes a T-BOX (Telematics BOX) module and a third-party APP (application) application. The left detection function related module includes an instrument display module, a vehicle light module, a horn module, an air conditioning control module, a window control module, a door control module, an intelligent key module, a vehicle ignition switch module, and a microphone module, etc. The body domain controller communicates with the left detection function related module and the gateway control module through a CAN bus, and the gateway control module communicates with the multimedia domain controller, the millimeter wave radar 1, and the millimeter wave radar 2 through a CAN bus. The multimedia domain controller communicates with the in-vehicle camera 1 and the in-vehicle camera 2 through an LVDS (Low-Voltage Differential Signaling) line, communicates with the microphone module through an I2S (Inter-IC Sound) bus, and communicates with the T-BOX module through an Ethernet.

[0079] The functions of the devices and modules in the living body left detection system are as follows:

[0080] The millimeter wave radar is used to detect the micro-movement and limb movement of the living body inside the vehicle by using the Doppler effect, so as to determine whether there is a living body inside the vehicle. The in-vehicle camera block is used to determine the type of the living body left inside the vehicle based on a living body recognition algorithm, such as an adult, a child, a pet, etc.

[0081] The multimedia domain controller is used to set the state of the left-behind detection function on the vehicle, including an open state, a closed state, and a delay detection state. When the left-behind detection function is in the open state, the life left-behind detection and reminder can be normally performed to remind the user that there is a child left in the vehicle. When the left-behind detection function is in the closed state, the life left-behind detection and reminder cannot be normally performed. When the normal life left-behind detection and reminder is in the delay detection state, the user can set the time length of the delay detection and reminder, such as delaying 5 minutes to perform the detection and reminder when there is a child in the vehicle.

[0082] The gateway control module is used for bus network signal forwarding and communication function of each communication module. The instrument display module is used to display whether the left-behind detection function is normally working. If the function is in a fault state, the instrument fault light will be lit to remind the user.

[0083] The car light module is used to remind the user or pedestrians near the vehicle that there is a child or other life left in the vehicle by flashing the car light. The horn module is used to remind the user or pedestrians near the vehicle that there is a child or other life left in the vehicle by sounding the horn. The T-BOX module is used to connect the vehicle and the user terminal (such as a mobile phone) APP network communication. The third-party application APP is a third-party application APP installed on the user terminal, which is used to connect with the vehicle through network signals and remind the user that there is a child or other life left in the vehicle through the push message.

[0084] The window control module is used to control the opening and closing of the window. When it is detected that there is a target life (such as a child) in the vehicle, the window is controlled to open or appropriately lower to ventilate, providing oxygen for the child in the vehicle. The air conditioner control module is used to control the opening and closing of the vehicle air conditioning system. When it is detected that there is a target life (such as a child) in the vehicle, the air conditioning system is controlled to open to ventilate and cool the vehicle, providing appropriate oxygen and temperature for the child in the vehicle.

[0085] The door control module is used to determine the state of the door, such as whether it is open, closed, or locked. The vehicle ignition switch module is used to determine whether the vehicle is in an off state. The smart key module is used for unlocking the door, remotely starting the vehicle, and remotely controlling the air conditioning system.

[0086] The life left-behind detection device (vehicle body domain controller) is used to detect the life left-behind in the vehicle through the above devices and modules, and to remind the life left-behind when it is detected that there is a target life in the vehicle, thereby improving the accuracy of life detection and timely reminding relevant personnel, and improving the user experience of using the vehicle.

[0087] In an embodiment, as shown in FIG. 3, a method for detecting a living body left in a vehicle is provided. Taking the method applied to the living body left detection device in FIG. 1 as an example, the method comprises the following steps:

[0088] S10: When the vehicle meets the preset detection condition, wake up the preset detection device inside the vehicle to jointly detect the living body inside the vehicle by optical and mechanical waves.

[0089] During the use of the vehicle, the living body left detection device needs to judge the whole vehicle state of the vehicle, so as to judge whether the vehicle meets the preset detection condition based on the whole vehicle state, and only when the vehicle meets the preset detection condition, the preset detection device inside the vehicle is started, so that the preset detection device is in a detection state, and the living body inside the vehicle is jointly detected by optical and mechanical waves through the preset detection device, that is, the living body left detection is performed on the inside of the vehicle. If the vehicle does not meet the preset detection condition, the preset detection device will not be woken up for living body left detection.

[0090] Among them, the preset detection condition at least includes that the vehicle is in an off state (that is, the engine ignition signal is K15=off), the vehicle is not in a transport mode and a fast silent mode, the door state of any one door of the vehicle is detected from open to closed, and finally all doors are detected to be closed.

[0091] It should be understood that the traditional child left detection method usually detects the child left in the vehicle when the vehicle is parked and off, and the detection accuracy is not high, and false detection or missed detection may occur. For example, when the vehicle suddenly stops due to a fault during driving, or the vehicle is in a fast silent mode for maintenance personnel to enter the vehicle for maintenance, false detection may occur when child left detection is performed. Or, when the vehicle is in a transport mode, the vehicle is transporting goods for a long distance, and the vehicle is driving on poor road conditions, which may cause the vehicle body to vibrate, and the related sensor may be unstable and prone to false detection (such as false off). Or, the user temporarily stops the vehicle for a short time and then starts the vehicle for driving, and false detection may occur when the vehicle is temporarily stopped for detection. In addition, in the traditional child left detection method, a single detection method is usually used for living body identification, for example, a single optical sensor (such as a camera, an infrared sensor inside the vehicle) or a single mechanical wave sensor (such as a millimeter wave radar, an ultrasonic wave radar) is used for optical identification of the living body. The single detection method has low accuracy, such as the optical sensor is also blocked by an obstacle, and the mechanical wave sensor cannot determine whether the living body is a child. False detection and missed detection may occur, and the user experience is poor.

[0092] In view of the above, on the one hand, the whole vehicle state of the vehicle is judged, and after the vehicle is turned off and parked, the interference of the transport mode and the fast silent mode and the like is excluded, and some possible false detection conditions are excluded through the change state of the vehicle door; on the other hand, when the vehicle meets the preset detection condition, the optical and mechanical wave combined detection of the living body in the vehicle in the present disclosure can also reduce the false detection and missed detection of a single detection method, improve the accuracy of the in-vehicle living body detection, and thus improve the user experience of using the vehicle. In addition, the above-mentioned method can also reduce the frequent living body left detection of the vehicle, and reduce the power consumption of the vehicle.

[0093] In other embodiments, the preset detection condition further includes that the left detection function of the vehicle is in an open state; and the change of the vehicle door state within a first preset time length (such as 1-3 min) is detected as: off-on-off, and finally all the vehicle doors are closed. The content of the preset detection condition is further refined, thereby further reducing the possibility of false detection and further reducing the frequent living body left detection and reducing the power consumption of the vehicle.

[0094] After it is determined that the vehicle meets the preset detection condition, the preset detection device in the vehicle is woken up, and in the process of the optical and mechanical wave combined detection of the living body in the vehicle, if it is determined according to the whole vehicle state that the vehicle does not currently meet the preset detection condition, that is, when the vehicle is not in the off state (the engine ignition signal is K15=ON), the vehicle is not in the transport mode or the fast silent mode, the left detection function is not opened, and any vehicle door of the vehicle is opened, the preset detection device is controlled to stop detecting in time, and the energy consumption required for detection is reduced.

[0095] In an embodiment, the preset detection device at least includes a millimeter wave radar and a camera, wherein the millimeter wave radar is used for mechanical wave detection of the living body in the vehicle; and the camera is used for optical detection of the living body in the vehicle. The millimeter wave radar and / or the camera are arranged in the front side area of the seat in the vehicle; or the millimeter wave radar and / or the camera are arranged in the ceiling area above the seat cushion in the vehicle. Arranging the millimeter wave radar and the camera in the front side area of the seat in the vehicle or in the ceiling area above the seat cushion can avoid the shielding of the in-vehicle structure (such as the vehicle seat and the child safety seat), can effectively identify various scenarios of the child left in the vehicle, such as the child lying in a blanket without limb movement and the child lying in a rear-facing safety seat and covering a blanket, has a wide detection range, and thus improves the accuracy of the in-vehicle living body detection.

[0096] In an embodiment, in order to further improve the detection range of the preset detection device and improve the accuracy of the in-vehicle life detection, a plurality of millimeter wave radars and a plurality of cameras can be provided, and each millimeter wave radar and each camera is arranged at different positions in the vehicle to cover the entire in-vehicle space. For example, the millimeter wave radars can include a first millimeter wave radar and a second millimeter wave radar, and the cameras can include a first camera and a second camera. The first millimeter wave radar and the first camera can be arranged at the area above the inner rearview mirror of the vehicle, and the second millimeter wave radar and the second camera can be arranged at the ceiling area above the armrest box in the vehicle. In this way, the millimeter wave radars and the cameras can have the best information acquisition field of view, and the detection range of the cameras and the millimeter wave radars can cover the areas where children may be left, such as the footrest area and the seat, so as to improve the detection range of the preset detection device and improve the accuracy of the in-vehicle life detection.

[0097] In another embodiment, considering that the area above the inner rearview mirror or the ceiling area above the armrest box of some vehicles is small, and the volume of some millimeter wave radars and cameras is large, it is difficult to install multiple sensor devices at the same time. As shown in FIG. 4, the first millimeter wave radar (millimeter wave radar 1) is arranged at the right A-pillar area in the vehicle, and the second millimeter wave radar (millimeter wave radar 2) is arranged at the left C-pillar area in the vehicle. The first camera is arranged at the area above the inner rearview mirror of the vehicle, and the second camera is arranged at the ceiling area above the armrest box in the vehicle. In this way, the millimeter wave radars and the cameras can have the best information acquisition field of view, and the in-vehicle design can also be considered to ensure the in-vehicle visual effect.

[0098] In other embodiments, the number and arrangement position of the millimeter wave radars and the cameras can also be adaptively modified according to the actual vehicle model and the in-vehicle structure, which will not be described here.

[0099] In other embodiments, the preset detection device can include a millimeter wave radar, a camera, a carbon dioxide concentration sensor (or a sound decibel sensor), etc. The preset detection device can perform optical, mechanical wave and carbon dioxide concentration (sound decibel) joint detection on the life in the vehicle to improve the detection accuracy.

[0100] S20: When it is detected that there is a target life in the vehicle, the vehicle is controlled to perform life left reminding.

[0101] The preset detection device in the vehicle is woken up, and optical and mechanical wave joint detection is performed on the life in the vehicle to determine whether there is a target life (such as a child or a pet) in the vehicle. When it is detected by the preset detection device that there is a target life in the vehicle, the life left detection device needs to control the vehicle to perform life left reminding.

[0102] For example, when the preset detection device detects that there is a target living body in the vehicle, the living body left detection device needs to control the vehicle to sound the horn, honk the horn, flash the lights, voice broadcast, terminal information (such as mobile phone message, mobile phone call, APP reminder) and the like in one or more ways, to realize the living body left reminding, so that the user or the surrounding pedestrians can learn in time that there is a left child in the vehicle, and ensure the safety of the child.

[0103] In the present disclosure, the vehicle state is first judged, and when the vehicle state meets the conditions of engine off, non-transportation mode and fast mute mode, the vehicle door is closed and all the vehicle doors are finally closed, the in-vehicle living body detection is performed, which can avoid detection in some unnecessary cases, reduce false detection, and further reduce false detection and missed detection through the joint detection of optical and mechanical waves by the preset detection device in the vehicle, improve the accuracy of living body detection and timely remind the relevant personnel, and thus improve the user experience of using the vehicle.

[0104] In an embodiment, in step S10, the joint detection of optical and mechanical waves on the living body in the vehicle includes the following steps:

[0105] S11: When the left detection function of the vehicle is in the delay detection state and the vehicle is in the locked state, after timing for the first time length, the joint detection of optical and mechanical waves on the living body in the vehicle is performed by the preset detection device.

[0106] In the present disclosure, the vehicle is provided with a left detection function, which includes three states of an open state, a closed state and a delay detection state. The user can enter the setting page of the left detection function through the related screen (such as the central control screen, the screen of the left detection function terminal, etc.), and set the state of the left detection function in the setting page. The delay detection state means that the joint detection of optical and mechanical waves on the living body in the vehicle is not immediately performed, but is delayed for a certain time length before detection. In the delay detection state, the time length of the delay detection can be set by the user.

[0107] After determining that the vehicle meets the preset detection condition, in the process of the joint detection of optical and mechanical waves on the living body in the vehicle, the living body left detection device needs to obtain the state of the vehicle and the left detection function of the vehicle in the delay detection state, so as to execute different detection strategies according to the delay detection state and the state of the vehicle.

[0108] When the vehicle's left-behind detection function is not in the delay detection state, and the vehicle is in the locked state, that is, the user has no delay detection requirement, and the vehicle is locked, timing is performed after waking up the preset detection device inside the vehicle, and after timing for a first duration, the preset detection device performs joint detection of the living body inside the vehicle through optical and mechanical waves. The locked state is a locking operation of the vehicle in response to the user's locking instruction (such as pressing the vehicle locking key), and when the vehicle is in the locked state, the structure (such as the window) on the vehicle is in the locked state.

[0109] S12: When the vehicle's left-behind detection function is not in the delay detection state, and the vehicle is not in the locked state, or when the left-behind detection function is in the delay detection state, after timing for a second duration, the preset detection device performs joint detection of the living body inside the vehicle through optical and mechanical waves.

[0110] When the vehicle's left-behind detection function is in the delay detection state, and the vehicle is not in the locked state, that is, the user has no delay detection requirement, but the vehicle is not locked, timing is performed after waking up the preset detection device inside the vehicle, and after timing for a second duration, the preset detection device performs joint detection of the living body inside the vehicle through optical and mechanical waves. Or, when the left-behind detection function is in the delay detection state, that is, the user has a delay detection requirement, timing is performed after waking up the preset detection device inside the vehicle, and after timing for a second duration, the preset detection device performs joint detection of the living body inside the vehicle through optical and mechanical waves.

[0111] The second duration is greater than the first duration. The second duration and the first duration are both durations that meet relevant regulations. For example, the first duration can be 9s, and the second duration can be 290s to meet the scene requirements in the child left-behind detection clause of the ENCAP 2023 regulation.

[0112] In the present disclosure, when the vehicle's left-behind detection function is not in the delay detection state, and the vehicle is in the locked state, joint detection of the living body inside the vehicle through optical and mechanical waves is performed by the preset detection device after timing for a first duration; when the vehicle's left-behind detection function is not in the delay detection state, and the vehicle is not in the locked state, or when the left-behind detection function is in the delay detection state, joint detection of the living body inside the vehicle through optical and mechanical waves is performed by the preset detection device after timing for a second duration. Different detection strategies are executed according to the state of the left-behind detection function and the state of the vehicle, reducing the interference of the living body left-behind reminder on the user due to premature detection, making the living body left-behind detection more intelligent, and improving the user's vehicle experience.

[0113] In an embodiment, the preset detection device includes a millimeter wave radar and a camera as shown in FIG. 4. In step S10 or step S11 or step 12, the joint detection of the life body in the vehicle interior by optical and mechanical waves is specifically as follows:

[0114] S11: Doppler detection is performed by the millimeter wave radar to detect whether there is a life body in the vehicle interior.

[0115] When the vehicle meets the preset detection condition, the life body left detection device wakes up the millimeter wave radar and the camera, and then performs Doppler detection by the millimeter wave radar, that is, the millimeter wave radar detects the micro-movement (for example, the fluctuation change range of the chest when the life body is sleeping) and the limb movement of the life body in the vehicle by using the Doppler effect, so as to detect whether there is a life body in the vehicle interior. The millimeter wave radar can detect the subtle life fluctuation through mechanical wave detection, and has high accuracy.

[0116] S12: When it is detected that there is a life body in the vehicle interior, the camera is used to collect a life body image, and the type of the life body is identified based on the life body image.

[0117] When it is detected by the millimeter wave radar that there is a life body in the vehicle interior, the life body left detection device collects a life body image by the camera, and identifies the type of the life body based on the life body image. For example, a life body recognition algorithm (model) is used to recognize and classify the life body in the life body image, so as to accurately and quickly obtain the type of the life body in the vehicle, such as adult, child, pet (such as cat, dog, rabbit) and the like. The camera detection effectively makes up for the shortcoming that the millimeter wave radar in the vehicle cannot judge the type of the life body.

[0118] In an embodiment, when the vehicle meets the preset detection condition, the prediction detection device is woken up, and the joint detection of the life body in the vehicle interior by optical and mechanical waves is also as follows: the life body left detection device first wakes up the millimeter wave radar in the vehicle, performs Doppler detection by the millimeter wave radar to detect whether there is a life body in the vehicle interior, and then wakes up the camera in the vehicle when it is detected by the millimeter wave radar that there is a life body in the vehicle interior, collects a life body image by the camera, and identifies the type of the life body based on the life body image. Since the power consumption of the millimeter wave radar is much lower than that of the camera, the millimeter wave radar is first woken up to detect whether there is a life body left in the vehicle, and the camera is woken up to detect when there is a life body left, which is beneficial to reduce the power consumption of the whole vehicle.

[0119] S13: When the type of the life body is a child, it is judged that the target life body is detected in the vehicle interior.

[0120] When the type of the living body is identified as a child, the living body left detection device determines that the target living body is detected in the vehicle. In other embodiments, the target living body can be other types of living bodies set by the user, such as a child, a pet, a person with a physical disability, etc. When the type of the living body is identified as a child, a pet, a person with a physical disability, etc., the living body left detection device can also determine that the target living body is detected in the vehicle, ensuring the safety of other types of living bodies and improving the user's vehicle experience.

[0121] In an embodiment, after identifying the type of the living body based on the living body image, it is first determined whether the type of the current living body in the vehicle is a non-child living body such as an adult or a pet. If the type of the current living body in the vehicle is not a non-child living body such as an adult or a pet, it can be considered that the living body in the vehicle is a child, and it can be considered that the target living body is detected in the vehicle. Since children are easily blocked by obstacles such as safety seats in the vehicle, adults are taller, and pets are more active, it is first determined whether the living body in the vehicle is an adult or a pet. If so, no living body left reminder will be given; if not, a living body left reminder (child left reminder) will be given. This approach can further improve the detection rate of children and reduce the missed detection rate of children.

[0122] In the present disclosure, Doppler detection is performed by a millimeter wave radar to detect whether a living body is present inside the vehicle. When a living body is detected inside the vehicle, a living body image is captured by a camera, and the type of the living body is identified based on the living body image. When the type of the living body is a child, it is determined that the target living body is detected in the vehicle. By using a detection scheme that combines a millimeter wave radar inside the vehicle and a camera inside the vehicle, the detection accuracy of a child left in the vehicle can be improved, the coverage scenarios of a child left in the vehicle can be increased, thereby effectively avoiding false detection caused by non-children left in the vehicle and avoiding interference to the user, thereby improving the user's vehicle experience.

[0123] In an embodiment, after step S10, i.e., after the joint detection of the living body inside the vehicle by optical and mechanical waves, the method further comprises the following steps:

[0124] S101: If the target living body is detected in the vehicle within a preset detection time, the vehicle is controlled to perform a living body left reminder;

[0125] S102: If the target living body is not detected in the vehicle within a preset detection time, the preset detection device is controlled to exit the detection state and enter a low-power consumption state.

[0126] After the vehicle meets the preset detection condition, the joint detection of the life body inside the vehicle by the optical and mechanical waves is performed, and the time is counted from the start time of the joint detection until the preset detection time length, which is a preset time length, and can be 10 minutes. If the target life body is detected in the vehicle by the preset detection device within the preset detection time length, step S20 is performed, that is, the vehicle is controlled to perform the life body left reminding; if the target life body is not detected in the vehicle by the preset detection device within the preset detection time length, the preset detection device is controlled to exit the detection state and enter the low-power consumption state, which can reduce the power consumption of the preset detection device, thereby reducing the power consumption of the whole vehicle.

[0127] In an embodiment, as shown in FIG. 5, after step S20, that is, after the vehicle is controlled to perform the life body left reminding, the method further includes the following steps:

[0128] S30: Counting the time after the vehicle is controlled to perform the life body left reminding.

[0129] S40: After the time is counted to the second preset time length, if the target life body is still detected in the vehicle, the vehicle is controlled to perform the preset safety measure, and the preset safety measure is used to provide oxygen for the inside of the vehicle and adjust the temperature inside the vehicle.

[0130] When the target life body is detected in the vehicle, the life body left detection device controls the vehicle to perform the life body left reminding, and then counts the time after the vehicle is controlled to perform the life body left reminding (such as the start time), until the time is counted to the second preset time length (such as 3-4 minutes), that is, after the second preset time length of the life body left reminding, the life body left detection device continues to detect the life body in the vehicle by the preset detection device, and if the target life body is still detected in the vehicle, the vehicle is controlled to perform the preset safety measure to ensure the safety of the life body (such as a child) in the vehicle. The preset safety measure is used to provide oxygen for the inside of the vehicle and adjust the temperature inside the vehicle to create a comfortable in-vehicle environment for the child and eliminate the risk of suffocation and heat death in the vehicle.

[0131] For example, controlling the vehicle to perform the preset safety measure can be to control the air conditioning system of the vehicle to start and / or open one or more vehicle windows, thereby providing oxygen for the inside of the vehicle and adjusting the temperature inside the vehicle. In order to ensure the safety of the property in the vehicle or the safety of the child (to prevent the child from being abducted by others), the vehicle window can be controlled to open (drop) to a preset safety gap (such as 2-5 cm), that is, oxygen can be provided for the inside of the vehicle and the temperature inside the vehicle can be adjusted, and other losses can also be ensured.

[0132] In an embodiment, to avoid excessive consumption of the vehicle's power for the execution of the preset safety measures, and to ensure the energy consumption of the vehicle, a time length for the execution of the preset safety measures is set, which can be 20-30 minutes. The execution time length of the preset safety measures can also be determined according to the current power (remaining power) of the vehicle. Different power ranges correspond to different execution time lengths. The more power, the longer the execution time length.

[0133] In the present disclosure, after the second preset time length of the life body left reminding is performed, if the target life body is still detected in the vehicle, the vehicle is controlled to execute the preset safety measures, which are used to provide oxygen for the vehicle interior and adjust the temperature in the vehicle interior, so as to ensure the safety of the life body (child) in the vehicle.

[0134] In an embodiment, when the vehicle is controlled to execute the preset safety measures, a safety measure execution prompt is also generated to send the safety measure execution reminder to the user of the vehicle through a remote information sending mode (such as a phone, a message, an APP information, etc.), so that the user can timely know the situation of the life body left in the vehicle and the execution of the safety measures. In the process of controlling the vehicle to execute the preset safety measures, when the safety measure execution prompt is generated, if the preset safety measures include controlling the air conditioning system of the vehicle to be turned on, the power of the vehicle is determined to determine whether the power of the vehicle can support the execution of the preset safety measures by the vehicle. If the power of the vehicle can support the execution of the preset safety measures, i.e., the vehicle is in a sufficient power mode, a first type of safety measure execution prompt is generated. The first type of safety measure execution prompt includes time (a certain year, month, day, hour, and minute), power of the vehicle, time length of the life body left in the vehicle, execution situation of the preset safety measures (such as execution time length of the preset safety measures), and release mode of the preset safety measures and the life body left reminding (such as remote release through a mobile phone or release through a vehicle key), to avoid the user not knowing how to operate and causing other effects. If the power of the vehicle cannot support the execution of the preset safety measures, i.e., the vehicle is in a low power mode, the vehicle is controlled not to execute or stop executing the preset safety measures, and a second type of safety measure execution prompt is generated. The second type of safety measure execution prompt includes time (a certain year, month, day, hour, and minute), power of the vehicle, time length of the life body left in the vehicle, execution situation of the preset safety measures (such as execution time length of the preset safety measures, and power is too low to continue execution), and life body left confirmation reminding, which requires the user to confirm the situation in the vehicle as soon as possible.

[0135] In an embodiment, after step S20, the method further includes the following steps:

[0136] S70: After the execution of the life body left reminding and / or preset safety measures, the life body inside the vehicle is detected again by the preset detection device through optical and mechanical wave detection.

[0137] S80: If the target life body is still detected inside the vehicle, the vehicle window is controlled to open a preset gap, and / or the vehicle is controlled to alarm to the alarm platform.

[0138] After the execution of the life body left reminding and / or preset safety measures, the life body inside the vehicle is detected again by the preset detection device through optical and mechanical wave detection. If the target life body is still detected inside the vehicle, the life body left reminding is not performed, but the vehicle window is controlled to open a preset gap to ensure air circulation inside and outside the vehicle, and / or the vehicle is controlled to alarm to the alarm platform so that the relevant police personnel can arrive at the vehicle location in time to take rescue measures.

[0139] In the present disclosure, if the target life body is still detected inside the vehicle after the execution of the life body left reminding and preset safety measures, the vehicle window is controlled to open a preset gap, and / or the vehicle is controlled to alarm to the alarm platform to ensure air circulation inside and outside the vehicle, so that the relevant police personnel can arrive at the vehicle location in time to take rescue measures.

[0140] In an embodiment, the life body left reminding includes a primary reminding stage and an upgraded reminding stage. As shown in FIG. 6, in step S20, i.e., the vehicle is controlled to perform the life body left reminding, which specifically includes the following steps:

[0141] S21: In the primary reminding stage, the vehicle is controlled to perform sound and light reminding until the duration of the primary reminding stage reaches a first reminding duration.

[0142] In the present disclosure, the primary reminding stage is the stage in which the preset detection device is woken up to perform life body left detection, and the target life body (such as a child) is detected for the first time and the life body left reminding is performed. The duration of the primary reminding stage is the first reminding duration.

[0143] In the present disclosure, the primary reminding stage is the stage in which the preset detection device is woken up to perform life body left detection, and the target life body (such as a child) is detected for the first time and the life body left reminding is performed. The duration of the primary reminding stage is the first reminding duration.

[0144] The screen displays the life body left prompt information, that is, the life body left prompt information is displayed through the vehicle screen. The vehicle screen includes a screen (such as a car screen or an instrument) arranged inside the vehicle and capable of providing information for viewing by the person outside the vehicle, and a screen arranged outside the vehicle. For example, the screen outside the vehicle can be arranged at a position such as a front hood, a front windshield area, a rear windshield, a roof, or the like, which is convenient for information browsing.

[0145] The life body left prompt information is voice broadcasted or screen displayed while the vehicle light flashes, so that the person outside the vehicle (pedestrian) can quickly know the life body left situation in the vehicle through voice broadcast and screen information display, so as to take corresponding rescue measures, and avoid the situation that the person outside the vehicle cannot know that there is a life body left in the vehicle due to the fact that the person outside the vehicle does not understand the meaning of the vehicle light flashing (vehicle honking).

[0146] In the primary reminding stage, the user can be near the vehicle, and the vehicle is controlled to give an acoustic and light reminder, so the user can timely notice the reminder, and thus the first reminding duration can be set to a relatively short duration, for example, 6s.

[0147] S22: After the primary reminding stage ends, when it is detected again that there is a target life body in the vehicle, the upgraded reminding stage is entered.

[0148] After the primary reminding stage ends, the life body in the vehicle is detected again by the preset detection device through optical and mechanical wave joint detection, and when it is detected again that there is a target life body in the vehicle, the upgraded reminding stage is entered.

[0149] In the primary reminding stage, the user can be near the vehicle, and the vehicle is controlled to give an acoustic and light reminder, so the user can timely notice the reminder, and thus the first reminding duration can be set to a relatively short duration, for example, 6s.

[0150] S23: In the upgraded reminding stage, the vehicle is controlled to give an acoustic and light reminder until the duration of the upgraded reminding stage reaches the second reminding duration.

[0151] In the upgrade reminding stage, the vehicle is controlled to perform sound and light reminding until the duration of the upgrade reminding stage reaches a second reminding duration. In the upgrade reminding stage, the user can be far away from the vehicle, and the reminding duration needs to be increased and / or the reminding intensity needs to be increased, therefore, the second reminding duration is greater than the first reminding duration, for example, the second reminding duration can be 25 minutes; the sound and light reminding in the upgrade reminding stage includes flashing of the vehicle lights, sounding of the vehicle horn (sound propagation is far), voice broadcast of the above-mentioned life body left prompting information, and / or display of the life body left prompting information on the screen.

[0152] In the upgrade reminding stage, the vehicle is controlled to perform sound and light reminding until the duration of the upgrade reminding stage reaches a second reminding duration. In the upgrade reminding stage, the user can be far away from the vehicle, and the reminding duration needs to be increased and / or the reminding intensity needs to be increased, therefore, the second reminding duration is greater than the first reminding duration, for example, the second reminding duration can be 25 minutes; the sound and light reminding in the upgrade reminding stage includes flashing of the vehicle lights, sounding of the vehicle horn (sound propagation is far), voice broadcast of the above-mentioned life body left prompting information, and / or display of the life body left prompting information on the screen.

[0153] In the upgrade reminding stage, the vehicle is controlled to perform sound and light reminding until the duration of the upgrade reminding stage reaches a second reminding duration. In the upgrade reminding stage, the user can be far away from the vehicle, and the reminding duration needs to be increased and / or the reminding intensity needs to be increased, therefore, the second reminding duration is greater than the first reminding duration, for example, the second reminding duration can be 25 minutes; the sound and light reminding in the upgrade reminding stage includes flashing of the vehicle lights, sounding of the vehicle horn (sound propagation is far), voice broadcast of the above-mentioned life body left prompting information, and / or display of the life body left prompting information on the screen.

[0154] In an embodiment, in step S21, i.e. in the primary reminding stage, the vehicle is controlled to perform sound and light reminding, specifically including the following steps:

[0155] S211: generating life body left prompting information and determining a detection duration for detecting that there is a target life body in the vehicle.

[0156] In the detection that there is a target life body in the vehicle, life body left prompting information needs to be generated, for example, the life body left prompting information includes the life body left situation in the vehicle, for example, there is a life body (child) left in the vehicle, please confirm the situation in the vehicle as soon as possible. In other embodiments, the life body left prompting information also includes the life body left situation in the vehicle and the reminding execution situation, for example, there is a life body (child) left in the vehicle, and the vehicle is in the process of flashing light (and sounding) reminding.

[0157] In addition, the life body left prompt information can also include the position of the target life body in the vehicle. In the joint detection of the life body in the vehicle by optical and mechanical waves, the specific position of the target life body in the vehicle can be determined by the preset detection position, such as the front seat (left or right) of the vehicle, the rear seat (left or right) of the vehicle, the cockpit floor, the passenger compartment floor, etc. By indicating the position of the target life body in the vehicle through the life body left prompt information, on the one hand, the position of the person (pedestrian) outside the vehicle can be confirmed, which is convenient for subsequent rescue, and on the other hand, the credibility of the prompt information can be improved, so as to avoid the person outside the vehicle ignoring the prompt information due to lack of trust.

[0158] At the same time, it is necessary to determine the detection duration for detecting the target life body in the vehicle at present, that is, the duration from the time when the vehicle meets the preset detection condition to the time when the target life body in the vehicle is detected for the first time. Then, it is judged whether the detection duration is greater than the preset calibration duration (which can be 9s, 10s).

[0159] S212: When the detection duration is less than or equal to the calibration duration, in the primary warning stage, the vehicle is controlled to perform sound and light warning.

[0160] Among them, the sound and light warning includes vehicle light flashing, voice broadcast and / or screen display of life body left prompt information.

[0161] When the detection duration is less than or equal to the calibration duration, it indicates that the time from the current time to the time when the vehicle is turned off and the door is locked is relatively short, and the vehicle user is likely to be still near the vehicle and not far away from the vehicle. Therefore, in the primary warning stage, the vehicle is controlled to perform sound and light warning, that is, the vehicle is controlled to perform vehicle light flashing, voice broadcast and / or screen display of life body left prompt information, until the first warning duration is reached. Through the sound and light warning of the vehicle, the user near the vehicle can be informed in time that there is a life body left in the vehicle, and handled in time.

[0162] S213: When the detection duration is greater than the calibration duration, in the primary warning stage, the vehicle is controlled to perform sound and light warning, and the life body left prompt information is sent to the user terminal to realize remote warning and prompting.

[0163] When the detection duration is greater than the calibration duration, it indicates that the current time is far away from the time when the vehicle is turned off and the vehicle door is locked, and the vehicle user is likely to be far away from the vehicle. Therefore, in this primary reminding stage, the life body left prompting information needs to be sent to the user terminal to achieve remote reminding and prompting, so that the user far away from the vehicle can learn about the life body left in the vehicle in time. At the same time, the vehicle needs to be controlled to perform sound and light reminding, that is, the vehicle needs to be controlled to perform light flashing, horn sounding, and voice broadcast of the life body left prompting information, until the first reminding duration is reached or the vehicle is unlocked. Through the upgraded sound and light reminding and remote information reminding, the user far away from the vehicle and the surrounding pedestrians can learn about the life body left in the vehicle in time and handle it in time.

[0164] In the embodiment, the life body left prompting information can be sent to the user terminal through the contact information (such as a telephone number, an email address) reserved in the vehicle or the App bound.

[0165] In an embodiment, the life body left prompting information includes a release mode of the life body left reminding. The life body left prompting information includes the release mode of the life body left reminding, which is used to remind the user that the vehicle can be remotely unlocked (for example, through a Bluetooth key or a vehicle APP on a mobile phone) to release the life body in the vehicle and release the life body left reminding. The life body left prompting information can enable the user to confirm the situation in the vehicle as soon as possible. If the user confirms that there is a child in the vehicle, the child risk can be released as soon as possible. If it is determined that there is no child in the vehicle, the sound and light reminding can be released through a key. The user is informed of the release mode of the reminding, so as to avoid other influences caused by the user's unawareness of how to operate. After receiving the life body left prompting information through the user terminal, the user can learn about the life body left situation in the vehicle and the release mode of the life body left reminding in time, and then remotely unlock the vehicle and release the life body left reminding through the release mode, thereby ending the life body left reminding process.

[0166] In the disclosure, the life body left prompting information is generated, and the detection duration for detecting that the target life body exists in the vehicle is determined. When the detection duration is less than or equal to the calibration duration, in the primary reminding stage, the vehicle is controlled to perform sound and light reminding, and the sound and light reminding includes light flashing, voice broadcast, and / or screen display of the life body left prompting information. When the detection duration is greater than the calibration duration, in the primary reminding stage, the vehicle is controlled to perform sound and light reminding, and the life body left prompting information is sent to the user terminal to achieve remote reminding and prompting. The specific execution steps of the life body left reminding in the primary reminding stage are clarified, different reminding strategies are executed according to different detection durations, the user and the surrounding pedestrians can learn about the life body left in the vehicle in time and handle it in time, the vehicle reminding intelligence is improved, and the user's vehicle experience is improved.

[0167] In an embodiment, the upgrade reminding stage includes a first upgrade stage and a second upgrade stage. As in step S23, in the upgrade reminding stage, the vehicle is controlled to perform sound and light reminding, specifically including the following steps:

[0168] S231: In the first upgrade stage, the life body left prompting information is sent to the user terminal, and the vehicle is controlled to perform sound and light reminding, and the life body left prompting information includes the release mode of the life body left reminding.

[0169] In the present disclosure, the upgrade reminding stage includes a first upgrade stage and a second upgrade stage.

[0170] After entering the upgrade reminding stage, the first upgrade stage is directly entered, in which the life body left prompting information is sent to the user terminal, and the vehicle is controlled to perform sound and light reminding, that is, the vehicle is controlled to flash the vehicle lights, sound the horn, and voice broadcast the life body left prompting information. This process realizes remote and on-site vehicle reminding, facilitates the user and surrounding pedestrians to learn about the life body left in the vehicle in a timely manner, and timely processing, thereby improving the intelligentization of vehicle reminding and the user vehicle experience.

[0171] After the life body left prompting information is sent to the user terminal, if the first upgrade stage has not received the release instruction of the life body left reminding sent by the user through the user terminal (such as the release instruction sent through the Bluetooth key or the vehicle APP) for a long time, the vehicle is controlled to continue to perform sound and light reminding until the duration of the first upgrade stage is the third reminding duration, the first upgrade stage ends, it is judged that the upgrade reminding stage of the vehicle ends, that is, the execution step of the life body left reminding ends, and the life body left reminding process is exited. The third reminding duration can be the same as the second reminding duration, both of which are 25 min.

[0172] S232: When the release instruction of the life body left reminding is received, if the target life body is still detected in the vehicle, the second upgrade stage is entered.

[0173] After the life body left prompting information is sent to the user terminal, if the first upgrade stage receives the release instruction of the life body left reminding sent by the user through the user terminal, the vehicle is controlled to stop sound and light reminding, and it is judged that the first upgrade stage ends. At this time, the life body in the vehicle needs to be detected again by the preset detection device through optical and mechanical wave joint detection, and if the target life body is still detected in the vehicle, the second upgrade stage is entered.

[0174] S233: In the second upgrade stage, the life body left prompting information is sent to the user terminal again, and the vehicle is controlled to perform sound and light reminding again.

[0175] In the second upgrade stage, the life body left prompt information is sent to the user terminal again, and the vehicle is controlled to perform sound and light reminding again. The vehicle is controlled to perform light flashing, horn sounding, and voice broadcast of the life body left prompt information, so as to inform the user or the surrounding pedestrians of the life body left in the vehicle in time, and help the target life body in the vehicle to escape from the trouble. In the second upgrade stage, the vehicle is controlled to perform sound and light reminding until the duration of the second upgrade stage reaches the fourth reminding duration, or until the vehicle door is relocked and no target life body is detected in the vehicle, and it is judged that the second upgrade stage ends. The fourth reminding duration can be 25 min.

[0176] After judging that the second upgrade stage ends, it is judged that the upgrade reminding stage of the vehicle ends, that is, the execution step of the life body left reminding ends, and the life body left reminding process is exited.

[0177] In the present disclosure, in the first upgrade stage, the life body left prompt information is sent to the user terminal, and the vehicle is controlled to perform sound and light reminding. When the cancel instruction of the life body left reminding is received, if the target life body is still detected in the vehicle, the second upgrade stage is entered. In the second upgrade stage, the life body left prompt information is sent to the user terminal again, and the vehicle is controlled to perform sound and light reminding again. The specific reminding process of the upgrade reminding stage is clarified, remote and on-site reminding of the vehicle is realized, the user and the surrounding pedestrians can know in time that there is a life body left in the vehicle, and the life body safety in the vehicle is further ensured. In addition, the intelligence of the vehicle reminding is improved, and the user experience of using the vehicle is improved.

[0178] In an embodiment, the life body left prompt information includes first type prompt information and second type prompt information, and different vehicles generate different types of prompt information. In the upgrade reminding stage (including the first upgrade stage and the second upgrade stage), the current power of the vehicle needs to be judged in real time to determine whether the power of the vehicle can support the vehicle to perform sound and light reminding for a long time, so that different reminding strategies are executed according to the current power of the vehicle, and different life body left prompt information is generated.

[0179] If the power of the vehicle can support the vehicle to perform sound and light reminding in the upgrade reminding stage, that is, the vehicle is in the sufficient power mode, the first type prompt information is generated. The first type prompt information includes time (a certain year, month, day, hour, and minute), the power of the vehicle, the life body left situation in the vehicle (such as the duration of the life body left in the vehicle), the execution situation of the life body left reminding (such as the duration of the sound and light reminding), the position of the target life body in the vehicle, and the cancel mode of the life body left reminding.

[0180] If the power of the vehicle cannot support the vehicle to perform the preset safety measure, that is, the vehicle is in a low power mode, the vehicle is controlled not to perform or to stop performing the preset safety measure, and second type prompt information is generated. The second type prompt information includes time (a certain year, month, day, hour, and minute), the power of the vehicle, the in-vehicle life body leaving situation (such as the time length of the in-vehicle life body leaving), the execution situation of the life body leaving reminding (such as the time length of the sound and light reminding, and the power being too low to continue execution), the position of the target life body in the vehicle, and the life body leaving confirmation reminding, which requires the user to confirm the in-vehicle situation as soon as possible. The content of the prompt information at each stage is different, so that the user can feel the urgency of the child left in the vehicle. In addition, different reminding strategies are executed in combination with the power situation of the whole vehicle, and the user is informed of the power situation and the reminding release mode, so that the user can understand the current whole vehicle situation and take the child out of the vehicle in time.

[0181] In an embodiment, in step S40, timing can be performed at the beginning time of the first upgrade stage, and after timing for a certain time length (such as 3 min), the joint detection of the life body in the vehicle through the preset detection device is performed again. If the target life body is still detected in the vehicle, the vehicle is controlled to perform the preset safety measure, and the execution time length of the preset safety measure can be 30 min. Since the primary reminding stage is short, the execution of the preset safety measure after the first upgrade stage can avoid the energy waste caused by the execution of the preset safety measure in the primary reminding stage.

[0182] In an embodiment, before step S10, before determining that the vehicle meets the preset detection condition, the method further includes the following steps:

[0183] S01: If an operation instruction of the user on the left detection function of the vehicle is received, the state of the left detection function is changed in response to the operation instruction, and whether the vehicle meets the preset detection condition is determined after the change. The left detection function is in a default on state.

[0184] Before determining that the vehicle meets the preset detection condition, during the use of the vehicle by the user, the life body left detection device needs to judge whether an operation instruction of the user on the left detection function of the vehicle is received. If the operation instruction of the user on the left detection function of the vehicle is received, the state of the left detection function is changed in response to the operation instruction, and whether the vehicle meets the preset detection condition is determined after the change. The left detection function is in a default on state, so that the left detection function is in the on state for a long time, the missed detection of the life body left detection is avoided, and the safety and experience of the use of the vehicle are ensured.

[0185] The user can enter the operation interface of the left-behind detection function on the vehicle through a related screen (such as a central control screen), and browse and operate the state and configuration information of the left-behind detection function in the operation interface. The left-behind detection function is provided with three states: an open state, a closed state, and a delay state, and the default setting of the left-behind detection function is the open state. Whether the user selects the open state in the current vehicle power-on cycle or not, the left-behind detection function will be restored to the open state in the next vehicle power-on cycle. When the user clicks the exclamation mark button in the vehicle setting item switch, the central control screen will pop up a window to display the usage instructions of the left-behind detection function, so as to facilitate the user to understand and use the function in more detail.

[0186] Specifically, in step S01, the state of the left-behind detection function is changed in response to the operation instruction, and specifically includes the following steps:

[0187] S011: When the operation instruction is a closing instruction, the user is prompted to confirm whether to close the left-behind detection function. When the user confirms to close the left-behind detection function, the state of the left-behind detection function is changed to the closed state, and the user is prompted that the left-behind detection function has been closed.

[0188] The user sends a closing instruction through the operation interface of the left-behind detection function, and the living body left-behind detection device receives the closing instruction of the user. Then, the user is prompted to confirm whether to close the left-behind detection function. When the user confirms to close the left-behind detection function, the state of the left-behind detection function is changed to the closed state, and the user is prompted that the left-behind detection function has been closed.

[0189] For example, the operation interface includes three options or buttons of open, close, and delay. When the user clicks the close option or button in the operation interface, a closing instruction is sent. At this time, a pop-up window will prompt the user: (child left-behind detection) please confirm again whether to close the child left-behind detection function. The user can select the “Yes” or “No” button in the pop-up window, as shown in FIG. 7. The vehicle defaults to the “No” button to avoid the function being closed due to user misoperation. When the user selects the “Yes” button in the pop-up window, it means that the user confirms to close the left-behind detection function, and the state of the left-behind detection function is changed to the closed state. The left-behind detection function will be closed this time, and a pop-up window is prompted through the central control screen, and an indicator light in the instrument is lit to prompt the user that the left-behind detection function has been closed.

[0190] S012: When the operation instruction is a delay instruction, the state of the left-behind detection function is changed to the delay detection state.

[0191] When the operation instruction is the delay instruction, the state of the left-behind detection function is changed to a delay detection state. In addition, if a delay detection time length input by the user is received, the delay detection time length input by the user is updated in the left-behind detection function, so as to subsequently perform delay detection based on the delay detection time length input by the user.

[0192] For example, when the user can click a delay option or button on the operation interface, that is, a delay instruction is sent, the left-behind detection function of the living body left-behind detection device is changed to a delay detection state. In addition, a pop-up window is prompted to the user: delay detection is started, do you want to customize the delay detection time length? The user can select the “Yes” or “No” button in the pop-up window, wherein the “No” button is the default of the whole vehicle, so as to avoid that the delay detection function is closed due to user misoperation. When the user selects the “Yes” button in the pop-up window, it indicates that the user needs to customize the delay detection time length, and the user is prompted to input the customized delay detection time length through the pop-up window or a setting interface, and the delay detection time length input by the user is updated in the left-behind detection function, so as to subsequently perform delay detection based on the delay detection time length input by the user.

[0193] In the present disclosure, the state of the left-behind detection function is changed according to different operation instructions, the configuration and state of the left-behind detection function can be set according to user needs, the left-behind detection function is more intelligent, and the user vehicle experience is improved.

[0194] In an embodiment, before step S10, before determining that the vehicle meets the preset detection condition, the method further includes the following steps:

[0195] S02: performing fault detection on the left-behind detection function on the vehicle;

[0196] S03: when it is detected that the left-behind detection function does not exist fault, determining whether the vehicle meets the preset detection condition, so as to wake up the preset detection device in the vehicle to perform left-behind detection on the vehicle when it is determined that the vehicle meets the preset detection condition;

[0197] S04: when it is detected that the left-behind detection function exists fault, performing function fault prompting.

[0198] Before determining that the vehicle meets the preset detection condition, the left-behind detection function on the vehicle needs to be detected for fault during the user vehicle process, and function fault prompting is performed when it is detected that the left-behind detection function exists fault. For example, the user is prompted through pop-up window information and an indicator light in the instrument, so as to remind the user that the left-behind detection function exists fault at all times, and avoid that an accident occurs due to that the user does not know the fault in time.

[0199] When it is detected that the left-behind detection function is not faulty, it is further determined whether the vehicle meets preset detection conditions, so as to wake up preset detection devices in the vehicle to perform left-behind detection on the vehicle interior, i.e., to perform joint detection of optical and mechanical waves on the living body in the vehicle interior, when it is determined that the vehicle meets the preset detection conditions.

[0200] In the present disclosure, first, the left-behind detection function on the vehicle is detected for faults; when it is detected that the left-behind detection function is not faulty, it is determined whether the vehicle meets preset detection conditions, so as to wake up preset detection devices in the vehicle to perform left-behind detection on the vehicle interior, when it is determined that the vehicle meets the preset detection conditions; when it is detected that the left-behind detection function is faulty, a function fault reminder is performed. The user is reminded in time that the left-behind detection function is faulty, so as to avoid accidents caused by the user not knowing the fault in time.
