Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and in particular relates to a seat belt control method, electronic equipment and vehicle for a vehicle. Background Technology

[0002] With the continuous development of electric vehicle technology, the configuration of many products in vehicles, such as seats, air conditioning, and audio systems, is also constantly improving. While improving the comfort and safety of seats, the corresponding seat belt systems also need to be innovated to meet different needs.

[0003] The intelligent seatbelt system is a vehicle-wide seatbelt usage system that collects numerous signals from sensors to determine the vehicle's status and determine the appropriate actions the seatbelts should take. For example, if radar or external cameras detect a sudden collision risk involving a person or vehicle in the vicinity, the vehicle's control system, including the Electronic Control Unit (ECU), assesses the risk level and determines whether to trigger the seatbelt locking action. If the assessment indicates a high risk, the locking action is triggered to restrain the webbing movement and provide effective protection for the occupants.

[0004] Currently, in actual vehicle driving, the seat belt operation is mostly controlled uniformly based on the overall vehicle status, which cannot meet the usage needs of different scenarios in the vehicle. Summary of the Invention

[0020] Alternatively, based on the passenger weight information of the person in the first seat, it can be determined that the person in the first seat is a child;

[0021] Alternatively, based on user input, the person in the first seat can be determined to be a child.

[0022] According to one embodiment of this application, controlling the action of at least one of the electronic vehicle sensing component and the mechanical vehicle sensing component corresponding to the seat based on the operating state information and the seating state information of the seat includes:

[0051] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0052] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0053] The following description, in conjunction with the accompanying drawings, details the vehicle seatbelt control method, vehicle seatbelt control device, electronic device, and readable storage medium provided in this application through specific embodiments and application scenarios.

[0054] Among them, the seat belt control method for vehicles can be applied to vehicles and can be executed by hardware or software in the vehicle.

[0055] like Figure 2 As shown, the vehicle system can be divided into a perception layer, a control layer, and an execution layer. The perception layer can collect numerous signals from various sensing devices, such as the vehicle's domain controller, Electronic Stability Program (ESP), Advanced Driver Assistance System (ADAS), radar, and vehicle attitude.

[0056] The Electronic Control Unit (ECU) in the control layer can analyze numerous signals from the perception layer to determine the overall vehicle status and provide the corresponding actions that the seat belts need to perform in the execution layer.

[0057] In actual implementation, the control layer can include power supply module, information parsing module, self-protection module, status monitoring module, drive module, event recording module, etc. The control layer can not only monitor and analyze various signals, but also output corresponding status to devices such as seat belts, coordinate with the actions of various systems on the vehicle, and make corresponding records.

[0058] In this embodiment of the application, the vehicle's seat belt system includes a seat belt and a retracting mechanism connected to the seat belt. The retracting mechanism includes an electronic vehicle sensing component and a mechanical vehicle sensing component. The retracting mechanism can lock the seat belt and also retract the seat belt.

[0059] Among them, the mechanical vehicle sensing component is a passive vehicle sensing structure. The mechanical vehicle sensing component can sense information such as vehicle acceleration and tilt angle. When the acceleration or tilt angle exceeds a certain threshold, the mechanical structure in the mechanical vehicle sensing component will automatically lock the seat belt without the need for control by the vehicle control layer.

[0060] The electronic vehicle sensing component is an active vehicle sensing structure that is controlled by the vehicle control layer. The vehicle control layer senses the vehicle's status information and controls the electronic vehicle sensing component to perform corresponding actions.

[0061] like Figure 1 As shown, the seat belt control method for this vehicle includes steps 110 and 120.

[0062] Step 110: Obtain the vehicle's operating status information and the seating status information of the vehicle's seats.

[0063] Among them, the vehicle's operating status information can be information that can characterize the overall vehicle status during the vehicle's operation, such as vehicle speed, vehicle posture, vehicle gear, surrounding environment, etc. The vehicle's operating status information can be collected through the vehicle's perception layer.

[0064] Seat occupancy status information is used to characterize the seat itself and the status of the people in the seat. For example, seat tilt angle, seat mode, seat is the driver's seat, the person's body type, and the person's movements. Seat occupancy status information can be collected through the vehicle's perception layer.

[0065] In this embodiment, the riding status information includes at least one of the occupant status information and seat mode information.

[0066] Among them, the personnel status information is used to characterize the current status of the person in the seat, such as whether they are driving while fatigued, whether they are a child, or whether they are resting.

[0067] Seat mode information is used to characterize the current state of the seat, such as the seat tilt angle, whether it is in zero gravity mode, and whether it is in rest mode. In zero gravity mode and rest mode, the seat cushion, backrest, and leg rest are adjusted to make the sitting or lying posture of the person in the seat more comfortable.

[0068] In this step, the vehicle's current operating status information and the occupancy status information of the seats in the vehicle are obtained in real time. For seats without passengers, their occupancy status information does not need to be obtained.

[0069] Step 120: Based on the operating status information and the seating status information, control the action of at least one of the electronic vehicle sensing components and mechanical vehicle sensing components corresponding to the seat.

[0070] In this step, based on the vehicle's operating status information and the seating status information of each seat, the electronic vehicle sensing components and / or mechanical vehicle sensing components corresponding to each seat are controlled. The seat belt of each seat can be in different states to meet the needs of different scenarios in the vehicle.

[0071] For example, a vehicle includes seats A, B, C, and D, where seat D is not occupied. The system obtains the vehicle's operating status information as well as the occupancy status information of each of the seats A, B, and C.

[0072] In this embodiment, the electronic vehicle sensing components and / or mechanical vehicle sensing components of seat A are controlled according to the seating status information of seat A and the vehicle operating status information. The electronic vehicle sensing components and / or mechanical vehicle sensing components of seat B are controlled according to the seating status information of seat B and the vehicle operating status information, and so on.

[0073] In actual operation, based on the operating status information and the seating status information, the action of the electronic vehicle sensing components corresponding to the seat can be controlled, the action of the mechanical vehicle sensing components corresponding to the seat can be controlled, or the action of the electronic vehicle sensing components and the mechanical vehicle sensing components corresponding to the seat can be controlled simultaneously.

[0074] For example, when the operating status information and the seat occupancy status information meet the locking trigger conditions, the electronic vehicle sensing components of the seat can be controlled to perform a locking action, actively locking the seat belt to ensure the safety of the occupants. It can also prevent the mechanical vehicle sensing components from failing to lock properly, effectively improving the vehicle's safety performance.

[0075] For example, when the operating status information and the seat occupancy status information do not meet the locking trigger conditions, suppressing the mechanical vehicle sensing component of the seat belt to perform actions can reduce the noise of the mechanical structure in the mechanical vehicle sensing component moving with the vehicle. While ensuring safety, the seat belt can be retracted and extended, improving the comfort of the passengers.

[0076] For example, during the mechanical vehicle sensing component that inhibits the seat belt, when the operating status information and the seat occupancy status information meet the locking trigger conditions, the electronic vehicle sensing component of the seat is controlled to perform a locking action, reducing mechanical noise while actively locking the seat belt, effectively improving the vehicle's safety performance.

[0077] It should be noted that for seats without passengers, the mechanical components of the seat belt can be suppressed from operating, reducing mechanical noise inside the vehicle and improving passenger comfort.

[0078] In related technologies, during actual vehicle driving, the seat belt operation is mostly controlled uniformly based on the overall vehicle status, which cannot meet the usage needs of different scenarios in the vehicle. The seat belt wearing experience of the passengers is poor, which may lead to some people not using seat belts, resulting in high safety risks.

[0079] In this embodiment, based on the operating status information and the seating status information of the seat, the action of at least one of the electronic vehicle sensing components and mechanical vehicle sensing components corresponding to the seat is controlled to accurately control the seat belt status. Different seats in the vehicle can correspond to different seat belt statuses, and the seat belt status can be flexibly controlled to meet the needs of different scenarios, which is conducive to improving user experience and reducing safety risks.

[0080] According to the vehicle seat belt control method provided in the embodiments of this application, by acquiring operating status information and seat occupancy status information, the action of electronic vehicle sensing components and / or mechanical vehicle sensing components corresponding to each seat can be controlled flexibly to control the seat belt status, meet the needs of different scenarios, effectively reduce safety risks, and reduce in-vehicle noise while ensuring safety, which helps to improve the comfort of passengers.

[0081] In some embodiments, controlling the action of at least one of the electronic vehicle sensing components and the mechanical vehicle sensing components corresponding to the seat, based on operating status information and seat occupancy status information, may include:

[0082] If the operating status information does not meet the vehicle seat belt locking conditions, and the seat belt corresponding to the first seat of the vehicle is in an unlocked state, based on the occupancy status information of the first seat, it is determined that the first seat meets the seat belt locking conditions, and the electronic vehicle sensing component corresponding to the first seat is controlled to perform the locking action.

[0083] Among them, the vehicle seat belt locking condition is a locking condition based on the operating status information. For example, when the vehicle speed, vehicle posture, and vehicle gear exceed a preset threshold, the operating status information meets the vehicle seat belt locking condition.

[0084] Seat belt locking conditions are based on passenger status information. For example, if a passenger in a seat is moving violently and there is a certain safety risk, the passenger status information meets the seat belt locking conditions. Another example is when a child is in a seat; if the passenger status information meets the seat belt locking conditions throughout the entire operation, the seat belt in the child's seat will remain locked during vehicle operation to ensure the safety of the passenger.

[0085] In this embodiment, the operating status information does not meet the vehicle seat belt locking conditions, that is, the current operating status of the vehicle will not trigger seat belt locking, the seat belt corresponding to the first seat in the vehicle is in an unlocked state, and neither the mechanical vehicle sensing component nor the electronic vehicle sensing component of the first seat locks the seat belt.

[0086] Based on the occupancy information of the first seat, if it is determined that the first seat meets the conditions for seat belt locking, the electronic vehicle sensing component corresponding to the first seat is controlled to perform a locking action, actively locking the seat belt, which can effectively improve the safety of the vehicle and the seat.

[0087] For example, if the vehicle's current speed is less than a preset threshold, the operating status information does not meet the conditions for locking the vehicle's seat belts, and the seat belts on the seats in the vehicle are not locked, the occupancy status information of the first seat indicates that the occupant in the first seat is shaking violently. The electronic vehicle sensing component corresponding to the first seat is then controlled to perform a locking action, locking the seat belt of the first seat to prevent the occupant in the first seat from bumping into their body due to shaking, thus ensuring the safety of the people in the vehicle.

[0088] It should be noted that when the operating status information does not meet the vehicle's seat belt locking conditions, the seat's electronic vehicle sensing components are controlled to perform the locking action by judging that the occupancy status information meets the seat belt locking conditions. This allows for flexible control of the seat belt status. Even when the operating status information is collected inaccurately or the processing time is too long, resulting in the inability to lock the seat belt in time, the seat belt can still be locked accurately and quickly, effectively improving vehicle safety.

[0089] In some embodiments, determining that the first seat meets the seat belt locking conditions based on the occupancy status information of the first seat includes:

[0090] If the first seat is the driver's seat and the occupant in the first seat is determined to be fatigued based on the occupant's condition information, then the first seat meets the seat belt locking conditions.

[0091] It is understandable that the first seat is the driver's seat, and the person in the first seat is the driver of the vehicle. When the driver is fatigued, it may lead to traffic accidents, posing an extremely high safety risk.

[0092] In this embodiment, for the first seat, which is the driver's seat, the seat status information of the first seat is acquired in real time. Based on the occupant status information in the seat status information, it is determined whether the occupant of the first seat is in a state of fatigue. When the occupant of the first seat is in a state of fatigue, there may be a risk of fatigued driving. If it is determined that the first seat meets the seat belt locking conditions, the electronic vehicle sensing component of the first seat is controlled to perform the locking action to ensure the safety of the occupant of the first seat.

[0093] In actual operation, when it is determined that the person in the first seat is fatigued based on the status information of the person in the first seat, the interactive device on the vehicle can be controlled to output a prompt message to remind the driver to rest and avoid driving while fatigued.

[0094] For example, if the system determines that the person in the first seat is fatigued based on their status information, it can control the vehicle's speakers to output a prompt voice or alarm sound to remind the driver to rest and avoid driving while fatigued.

[0095] For example, if the system determines that the person in the first seat is fatigued based on their status information, it can control the display screen on the vehicle to show a prompt message to remind the driver to rest and avoid driving while fatigued.

[0096] It should be noted that when the system determines that the person in the first seat is fatigued based on their status information, the vehicle's control layer can also limit the vehicle's speed to improve safety.

[0097] In some embodiments, determining that the person in the first seat is fatigued based on the occupant status information of the first seat includes:

[0098] Based on at least one of the head features, eye features, and head movement features of the person in the first seat, it is determined that the person in the first seat is in a state of fatigue.

[0099] In this embodiment, an image acquisition device such as a camera can be installed on the vehicle to collect the status information of the person in the first seat in real time. By detecting one or more combinations of head features, eye features and head movement features of the person in the first seat, it can be determined whether the person in the first seat is in a state of fatigue.

[0100] Among them, head features can represent information such as head size and head shape, eye features can represent information such as eye size, eye opening, eye closing, and blinking frequency, and head movement features can represent information such as head movement trajectory and head position.

[0101] Understandably, fatigue driving detection and recognition algorithms can be used to analyze one or more combinations of head features, eye features, and head movement features to determine whether the person in the first seat is fatigued.

[0102] The following is a specific example.

[0103] The first seat is the driver's seat. If the vehicle's operating status information does not trigger the seat belt locking condition, the camera will capture the head features, eye features, and head movement features of the person in the first seat to determine whether the driver is fatigued.

[0104] When fatigue is detected, a voice prompt is given. At the same time, the ECU determines that the person in the first seat is fatigued and there is a safety risk. The conditions for triggering the seat belt locking are met, and the electronic vehicle sensing components of the first seat are controlled to perform the locking action, restraining the movement of the seat belt and ensuring the safety of the person.

[0105] In some embodiments, determining that the first seat meets the seat belt locking conditions based on the occupancy status information of the first seat includes:

[0106] If, based on the occupant status information of the first seat, it is determined that the occupant of the first seat is a child, then the first seat meets the seat belt locking conditions.

[0107] In this embodiment, when the person in the first seat is a child, it is determined that the first seat meets the seat belt locking conditions, and the electronic vehicle sensing component of the first seat is controlled to perform the locking action to ensure the safety of the person in the first seat.

[0108] It should be noted that when the person in the first seat is a child, the seat belt in the first seat will remain locked throughout the entire vehicle operation to ensure the child's safety.

[0109] In practice, the status information of the person in the first seat can be obtained through at least three methods to determine whether the person in the first seat is a child.

[0110] Firstly, image recognition identifies the person in the first seat as a child.

[0111] In some embodiments, determining that the person in the first seat is a child based on the person's status information in the first seat may include: determining that the person in the first seat is a child based on the riding image information corresponding to the person in the first seat.

[0112] In this embodiment, an image acquisition device such as a camera can be installed on the vehicle to collect the status information of the person in the first seat in real time. By detecting the facial features and body features of the person in the first seat, it can be determined whether the person in the first seat is a child.

[0113] Secondly, the person in the first seat is identified as a child by weight.

[0114] In some embodiments, determining that the person in the first seat is a child based on the person's status information in the first seat may include: determining that the person in the first seat is a child based on the person's weight information.

[0115] In this embodiment, a weight sensor can be installed on the vehicle to collect the status information of the person in the first seat in real time, sense the weight of the person in the seat, and determine whether the person in the first seat is a child.

[0116] In practice, image recognition and weight recognition can be combined to determine whether the person in the first seat is a child.

[0117] Third, the user input determines that the person in the first seat is a child.

[0118] In some embodiments, determining that the person in the first seat is a child based on the person's status information in the first seat may include: determining that the person in the first seat is a child based on user input information.

[0119] In this embodiment, the vehicle receives user input information and determines that the person in the first seat is a child. The user input can be in the form of touch operation input, physical button input, voice input, etc., or other forms, including but not limited to character input. The specific form can be determined according to actual needs, and this embodiment does not limit it.

[0120] In some embodiments, based on operating status information and seat occupancy status information, controlling the action of at least one of the electronic vehicle sensing components and mechanical vehicle sensing components corresponding to the seat includes:

[0121] If the operating status information does not meet the vehicle seat belt locking conditions, based on the occupancy status information of the second seat, it is determined that the second seat meets the seat belt adjustment conditions, and the mechanical vehicle sensing components corresponding to the second seat are inhibited from performing actions.

[0122] In this embodiment, if the vehicle's operating status information does not meet the vehicle's seatbelt locking conditions, the mechanical and electronic vehicle sensing components on the vehicle will not lock the seatbelt. At this time, based on the second seat's seating status information, it is determined that the second seat meets the seatbelt adjustment conditions, suppressing the mechanical vehicle sensing components from performing actions, reducing the noise of the mechanical structure in the mechanical vehicle sensing components moving with the vehicle, and allowing the seatbelt to be freely extended and retracted, thereby improving the comfort of the occupants while ensuring a safe environment.

[0123] It should be noted that the fact that the second seat meets the seat belt adjustment requirements indicates that the free retraction and extension of the seat belt on the second seat will not affect the vehicle's safety.

[0124] For example, if the vehicle is traveling at a low, constant speed, the vehicle's operating status information does not meet the conditions for locking the seat belts, the person in the second seat is not a child, and the person's body is not moving significantly, it can be determined that the second seat meets the conditions for adjusting the seat belts, suppressing the mechanical sensing components from performing actions, reducing in-vehicle noise, and improving in-vehicle comfort.

[0125] Understandably, while suppressing the mechanical sensor components corresponding to the second seat from performing their actions, the vehicle's control layer can still control the actions of the electronic sensor components. When changes in operating status information and / or passenger status information cause the second seat to meet the seat belt locking conditions, the vehicle's control layer can quickly control the electronic sensor components to lock the seat belt, or release the suppression of the mechanical sensor components, allowing the mechanical sensor components to automatically lock the seat belt.

[0126] In some embodiments, determining whether the second seat meets the seat belt adjustment conditions based on the occupancy status information of the second seat includes:

[0127] Based on the seat mode information of the second seat, if it is determined that the second seat is in zero-gravity mode or rest mode, then it is determined that the second seat meets the seat belt adjustment conditions.

[0128] In this embodiment, based on the seat mode information of the second seat, when it is determined that the second seat is in zero-gravity mode or rest mode, it is determined that the second seat meets the seat belt adjustment conditions, suppressing the mechanical vehicle sensing components from performing actions, and the seat belt of the second seat can be freely extended and retracted, reducing in-vehicle noise while improving in-vehicle comfort.

[0129] In practice, the second seat can be determined to be in zero-gravity mode or rest mode based on the mode information input by the user and by detecting the rotation angle of the seat back and seat cushion.

[0130] In related technologies, during actual vehicle driving, the seat belts are mostly controlled uniformly according to the overall vehicle status. For zero-gravity seats or non-drivers who need to rest, the seat belts restrict body movement and seat adjustment, which cannot meet the usage needs.

[0131] In this embodiment, the seat belt on the second seat in zero-gravity mode or rest mode can be pulled out and used normally. Under the premise of ensuring vehicle safety, the seat rotation angle can also be freely adjusted to improve the comfort of passengers.

[0132] In some embodiments, after acquiring vehicle operating status information and seat occupancy status information, the vehicle seatbelt control method may further include:

[0133] When the operating status information meets the conditions for locking the vehicle's seat belts, the electronic vehicle sensing components corresponding to the seats in the vehicle are controlled to perform the locking action.

[0134] In this embodiment, when the vehicle's operating status information meets the vehicle seat belt locking conditions, the electronic vehicle sensing component corresponding to the seat in the vehicle is controlled to perform a locking action to restrict the movement of the seat belt. At this time, if the mechanical vehicle sensing component is not suppressed, the mechanical vehicle sensing component can also automatically perform a locking action.

[0135] For example, the vehicle samples the vehicle's operating status information through the perception layer. When radar, external cameras, and other sensors detect people or vehicles around the vehicle and there is a risk of collision, the control layer ECU can assess the risk level as high and control the electronic vehicle sensing components corresponding to the seats in the vehicle to perform locking actions, such as locking the seat belts, to ensure the safety of the people in the vehicle. At the same time, the judgment result is sent out as a message and recorded.

[0136] In some embodiments, the operating status information includes at least one of vehicle speed information, vehicle acceleration information, environmental obstacle information, and vehicle tilt angle information.

[0137] The vehicle speed information includes the vehicle's current speed and average speed, while the vehicle acceleration information includes the current acceleration.

[0138] Environmental obstacle information is used to characterize the obstacles present in the environment in which the vehicle is located. It can be obtained by sampling through sensors such as cameras and radar on the vehicle.

[0139] Vehicle tilt angle information is used to characterize the vehicle's current pose state, and can be obtained by sampling through inertial sensors, ranging sensors, etc. on the vehicle.

[0140] It should be noted that the mechanical structure in the mechanical vehicle sensing component can also sense information such as vehicle acceleration and tilt angle. When the acceleration, tilt angle and other information exceed the preset threshold, that is, when the operating status information meets the vehicle seat belt locking conditions, the mechanical vehicle sensing component can automatically lock the seat belt.

[0141] In actual operation, the vehicle's operating status information includes a combination of one or more of the following: vehicle speed information, vehicle acceleration information, environmental obstacle information, and vehicle tilt angle information. Corresponding seat belt locking conditions are set for different operating status information (e.g., compared with a preset threshold). When the operating status information meets the vehicle seat belt locking conditions, the seat belt is locked. When the operating status information does not meet the vehicle seat belt locking conditions, the seat belt action is controlled by electronic vehicle sensing components and / or mechanical vehicle sensing components, combined with the seat occupancy status information.

[0142] The following is a specific example.

[0143] like Figure 3 As shown, after the vehicle system is powered on, the ECU is first activated and performs initialization definition. After initialization is completed, the seat belt status is immediately confirmed, and the status of each sensing terminal on the vehicle is confirmed. If the status does not meet the set status (some sensors are malfunctioning and cannot sense signals), the status information will be uploaded to the background, the battery device will be powered off, the mechanical vehicle sensing components will be activated, the corresponding information code will be generated, and it will be incorporated into the system's data stream processing.

[0144] When the set conditions are met, the vehicle completes the standby confirmation and enters the standby state. In the standby state, the ECU will receive the corresponding operating status information in real time, monitor the demand signals, and determine the trigger conditions.

[0145] The system compares the threshold corresponding to the running status information, calculates and judges the results. If the triggering condition is not met, it will continuously capture and compare data. If the triggering condition is met, it will execute the corresponding action, upload the execution action record, and output the execution parameters.

[0146] like Figure 4As shown, it monitors seatbelt wearing information to determine if there is anyone in the seat, and monitors the vehicle's operating status information during vehicle operation.

[0147] When the operating status information meets the vehicle seat belt locking conditions, the seat belt is locked. When the operating status information does not meet the vehicle seat belt locking conditions, the judgment is made in conjunction with the seat occupancy information.

[0148] By detecting facial and eye features through facial recognition, it can determine whether the driver is in a state of fatigue. If fatigue is detected, a voice prompt will be given. At the same time, the ECU determines that the person in the first seat is fatigued and there is a safety risk. If the conditions for triggering the seat belt locking are met, the electronic vehicle sensing component will be controlled to execute the locking action, restrain the movement of the seat belt, and ensure the safety of the occupants.

[0149] When the first seat is occupied by a child, the seat belt will remain locked throughout the vehicle's operation, ensuring the child's safety under all conditions.

[0150] When the seat is in zero-gravity mode or rest mode, the seat belt can be pulled out and used normally. At the same time, the seat status information is monitored. Under the premise of ensuring vehicle safety, the seat rotation angle can also be freely adjusted to improve comfort.

[0151] like Figure 5 As shown, when the first relay 607 is energized, the valve core 606 is attracted, and the valve core 606 retracts downward, causing the rocker arm 605 to rotate counterclockwise around the fulcrum. This causes the mechanical vehicle sensing mechanism's follow-up pawl 610 to rotate downward, thus enabling the mechanical vehicle sensing mechanism to suppress the seat belt to perform its action. The steel ball 609 no longer rotates with the vehicle's movement, which can reduce noise.

[0152] like Figure 6 As shown, the mechanical vehicle sensing mechanism is suppressed from performing its action. At the same time, the second relay 611 is energized, the locking lever 612 pops out and engages with the ratchet teeth 604, and the electronic vehicle sensing mechanism performs the locking action, thereby restraining the actions of the people on the vehicle.

[0153] In actual implementation, when the mechanical sensing mechanism is not inhibited from performing its actions, the mechanical sensing mechanism is in a decoupled state.

[0154] When the seat belt system is powered off or malfunctions, the ECU controls the first relay 607 and the second relay 611 to be powered off simultaneously, and the mechanical vehicle sensing mechanism is activated. At this time, the seat belt can still be locked.

[0155] In this embodiment, by suppressing the mechanical vehicle sensing mechanism from performing its actions, the seat belt can be freely extended and retracted, which can meet the needs of zero-gravity seat operation and large-angle seat adjustment, while suppressing vehicle noise and improving user comfort. The electronic vehicle sensing mechanism can achieve active locking to ensure the safety of the occupants.

[0156] The vehicle seatbelt control method provided in this application can be executed by a vehicle seatbelt control device. This application uses the example of a vehicle seatbelt control device executing the vehicle seatbelt control method to illustrate the vehicle seatbelt control device provided in this application.

[0158] like Figure 7 As shown, the seatbelt control device of the vehicle includes:

[0159] The acquisition module 710 is used to acquire the vehicle's operating status information and the seating status information of the seats in the vehicle.

[0160] The processing module 720 is used to control the action of at least one of the electronic vehicle sensing components and mechanical vehicle sensing components corresponding to the seat based on the operating status information and the seating status information.

[0163] If the operating status information does not meet the vehicle seat belt locking conditions, and the seat belt corresponding to the first seat of the vehicle is in an unlocked state, based on the occupancy status information of the first seat, it is determined that the first seat meets the seat belt locking conditions, and the electronic vehicle sensing component corresponding to the first seat is controlled to perform the locking action.

[0169] If, based on the occupant status information of the first seat, it is determined that the occupant of the first seat is a child, then the first seat meets the seat belt locking conditions.

[0170] In some embodiments, the processing module 720 is configured to determine, based on the occupant status information of the first seat, that the occupant of the first seat is a child, including:

[0171] Based on the seating image information corresponding to the person in the first seat, it was determined that the person in the first seat was a child;

[0172] Alternatively, based on the passenger weight information of the person in the first seat, it can be determined that the person in the first seat is a child;

[0173] Alternatively, based on user input, the person in the first seat can be identified as a child.

[0174] In some embodiments, the processing module 720 is configured to control the action of at least one of the electronic vehicle sensing components and the mechanical vehicle sensing components corresponding to the seat based on the operating status information and the seating status information, including:

[0175] If the operating status information does not meet the vehicle seat belt locking conditions, based on the occupancy status information of the second seat, it is determined that the second seat meets the seat belt adjustment conditions, and the mechanical vehicle sensing components corresponding to the second seat are inhibited from performing actions.

[0176] In some embodiments, the processing module 720 is configured to determine, based on the occupancy status information of the second seat, that the second seat meets the seat belt adjustment conditions, including:

[0177] Based on the seating mode information of the second seat's occupancy status, if it is determined that the second seat is in zero-gravity mode or rest mode, then it is determined that the second seat meets the seat belt adjustment conditions.

[0178] In some embodiments, after acquiring the vehicle's operating status information, the processing module 720 is further configured to control the electronic vehicle sensing component corresponding to the seat in the vehicle to perform a locking action if the operating status information meets the vehicle seat belt locking conditions.

[0179] In some embodiments, the operating status information includes at least one of vehicle speed information, vehicle acceleration information, environmental obstacle information, and vehicle tilt angle information.

[0180] The seatbelt control device for a vehicle in this application embodiment can be an electronic device or a component of an electronic device, such as an integrated circuit or a chip.

[0181] The vehicle seat belt control device provided in this application embodiment can realize the various processes implemented in the above method embodiments, and will not be described again here to avoid repetition.

[0182] In some embodiments, such as Figure 8 As shown, this application embodiment also provides an electronic device 800, including a processor 801, a memory 802, and a computer program stored in the memory 802 and executable on the processor 801. When the program is executed by the processor 801, it implements the various processes of the above-described vehicle seat belt control method embodiment and can achieve the same technical effect. To avoid repetition, it will not be described again here.

[0183] It should be noted that the electronic devices in the embodiments of this application include the mobile electronic devices and non-mobile electronic devices described above.

[0184] This application also provides a vehicle.

[0185] The vehicle includes a seat belt system and electronic equipment 800 as described above. The seat belt system includes a seat belt and a retractor mechanism connected to the seat belt. The retractor mechanism includes an electronic vehicle sensing component and a mechanical vehicle sensing component. Electronic equipment 800 is connected to the seat belt system.

[0186] Among them, the mechanical vehicle sensing component is a passive vehicle sensing structure. When the vehicle speed exceeds a certain threshold or there is a sudden braking, the mechanical structure in the mechanical vehicle sensing component will automatically lock the seat belt without the need for control by the vehicle control layer; the electronic vehicle sensing component is an active vehicle sensing structure that is controlled by the vehicle control layer and performs corresponding actions.

[0187] For example, when the operating status information and the seat occupancy status information meet the locking trigger conditions, the electronic device 800 can control the seat's electronic vehicle sensing component to perform a locking action, actively locking the seat belt to ensure the safety of the occupants. It can also prevent the mechanical vehicle sensing component from failing to lock properly, effectively improving the vehicle's safety performance.

[0188] For example, when the operating status information and the seat occupancy status information do not meet the locking trigger conditions, the electronic device 800 can suppress the mechanical vehicle sensing component of the seat belt from performing actions. This can reduce the noise of the mechanical structure in the mechanical vehicle sensing component moving with the vehicle, ensuring safety while allowing the seat belt to be retracted and extended, improving the comfort of the passengers.

[0189] For example, during the operation of the mechanical vehicle sensing component that inhibits the seat belt, when the operating status information and the seat occupancy status information meet the locking trigger conditions, the electronic device 800 controls the electronic vehicle sensing component of the seat to perform a locking action, reducing mechanical noise while actively locking the seat belt, effectively improving the vehicle's safety performance.

[0190] It should be noted that for seats without passengers, the mechanical components of the seat belt can be suppressed from operating, reducing mechanical noise inside the vehicle and improving passenger comfort.

[0191] According to the vehicle provided in the embodiments of this application, by acquiring operating status information and seat occupancy status information, the electronic vehicle sensing components and / or mechanical vehicle sensing components corresponding to each seat can be controlled to flexibly control the seat belt status, meet the needs of different scenarios, effectively reduce safety risks, and reduce in-vehicle noise while ensuring safety, thus helping to improve the comfort of passengers.
