Abstract
Description
Technical Field
[0001] This application relates to the field of door lock technology, and in particular to a vehicle door lock early warning method, device, vehicle door lock, vehicle, and storage medium. Background Technology
[0002] The car door lock has two states when switching from fully open to fully locked: half-lock and fully locked. When the door is open, both the half-lock and fully lock switches are engaged. When the door switches from fully open to half-lock, the half-lock switch is disengaged. When the door switches from half-lock to fully locked, the fully lock switch is disengaged.
[0003] The current door lock bolt can remain in any position between the fully open and partially locked states. Accidental contact with the bolt can cause it to remain in this state. If the door is closed in this condition, the outer side of the bolt will strike the latch, causing the bolt to enter a partially locked or even fully locked state without engaging the latch. At this point, the door lock is engaged, but because the door is not closed, there is a significant security risk. Summary of the Invention
[0004] In view of this, the present application provides a vehicle door lock early warning method, device, vehicle door lock, vehicle and storage medium, which can effectively solve the problem of the lock tongue being accidentally touched and remaining between the fully open and half-locked states. At this time, the door lock is in the locked state. Under this situation, the operation of closing the car door will result in the door not being actually closed, which poses a significant safety hazard.
[0005] In a first aspect, embodiments of this application provide a vehicle door lock, including: The bolt is driven by the bolt pivot to move between the fully open, half-locked and fully locked positions; A spring assembly is mounted on the bolt shaft at one end and fixed to the bolt at the other end. When the bolt deviates from the fully open position, the spring assembly undergoes elastic torsion and generates a restoring force that returns the bolt to the fully open position. The warning switch assembly is installed on the lock housing and is used to output different level signals according to the position of the lock tongue. When the level signal is the target level signal, it triggers the vehicle controller to analyze the target door image to determine the opening and closing status of the target door. When the opening and closing status is open, it generates a false lock warning command.
[0006] Secondly, embodiments of this application provide a vehicle, including a vehicle door lock and a vehicle controller; The vehicle controller is electrically connected to the warning switch assembly and is used to collect the level signal output by the warning switch assembly in real time. When the level signal is switched to the target level signal, the target door image is analyzed to determine the opening and closing status of the target door. When the opening and closing status is open, a false lock warning command is generated.
[0007] Thirdly, embodiments of this application provide a vehicle door lock early warning method, the method comprising: When the bolt is not engaged with the latch, the level signal output by the warning switch assembly is detected in real time, and the level signal is used to characterize the position information of the bolt. When the level signal is switched to the target level signal, the target car door image is acquired; The target door image is analyzed to determine the open / closed state of the target door. When the open / closed state is the open state, a false lock warning command is generated.
[0008] Fourthly, embodiments of this application provide a vehicle door lock warning device, the device comprising: The detection module is used to detect the level signal output by the warning switch component in real time when the bolt is not engaged with the latch. The level signal is used to characterize the position information of the bolt. The acquisition module is used to acquire an image of the target car door when the level signal is switched to the target level signal; The analysis module is used to analyze the target door image to determine the opening and closing status of the target door. When the opening and closing status is open, a false lock warning command is generated.
[0009] Fifthly, this application also provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, performs the following steps: When the bolt is not engaged with the latch, the level signal output by the warning switch assembly is detected in real time, and the level signal is used to characterize the position information of the bolt. When the level signal is switched to the target level signal, the target car door image is acquired; The target door image is analyzed to determine the open / closed state of the target door. When the open / closed state is the open state, a false lock warning command is generated.
[0010] The embodiments of this application have the following beneficial effects: By adding a spring assembly and a warning switch assembly to the traditional car door lock, the vehicle door lock tongue is kept fully open by the newly added spring assembly. On the other hand, the existing vehicle camera uses visual images, combined with the newly added warning switch assembly, to output different level signals to identify the possibility of false door lock and issue a warning for false door lock, thereby improving vehicle safety.

Detailed Implementation
[0013] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0014] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0015] In the following text, the terms "comprising," "having," and their cognates, which may be used in various embodiments of this application, are intended only to indicate a particular feature, number, step, operation, element, component, or combination thereof, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations thereof, or adding the possibility of one or more combinations thereof. Furthermore, the terms "first," "second," "third," etc., are used only for distinguishing descriptions and should not be construed as indicating or implying relative importance.
[0016] Unless otherwise specified, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which the various embodiments of this application pertain. Terms (such as those defined in a generally used dictionary) shall be interpreted as having the same meaning as in the context of the relevant technical field and shall not be interpreted as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.
[0017] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0018] To address the aforementioned technical problems, this application provides a vehicle door lock warning method, device, vehicle door lock, vehicle, and storage medium. This application adds a spring assembly and a warning switch assembly to a traditional vehicle door lock: on the one hand, the newly added spring assembly keeps the vehicle door lock tongue fully open; on the other hand, it uses an existing vehicle camera to output different level signals based on visual images, combined with the newly added warning switch assembly, to identify the possibility of a false lock and provide a warning, thereby improving vehicle security.
[0019] The following describes the vehicle door lock using specific embodiments. The vehicle door lock includes: The bolt is driven by the bolt pivot to move between the fully open, half-locked and fully locked positions. The spring assembly is mounted on the bolt shaft at one end and fixed to the bolt at the other end. When the bolt deviates from the fully open position, the spring assembly undergoes elastic torsion and generates a restoring force that returns the bolt to the fully open position. The warning switch assembly, installed on the lock housing, is used to output different level signals according to the position of the lock tongue. When the level signal is the target level signal, it triggers the vehicle controller to analyze the target door image to determine the opening and closing status of the target door. When the opening and closing status is open, it generates a false lock warning command.
[0020] Among them, the latch pivot refers to the rigid shaft structure in the door lock structure used to support and drive the latch to rotate around it.
[0021] The latch is a metal moving part in a car door lock that directly engages with or disengages from the door latch. It has a hook-shaped or tongue-shaped structure and can move around the latch axis in three positions: fully open, half-locked, and fully locked.
[0022] A latch is a rigid metal component fixed to the side of a vehicle body. Its shape matches the outline of the latch and is used to be engaged and locked by the latch during the closing process.
[0023] refer to Figure 1The spring assembly refers to the torsion spring installed between the bolt shaft and the bolt body. One end is fixed to the shaft, and the other end is fixed to the bolt base. When the bolt deviates from the fully open position, the spring assembly is torsionally stored and continuously applies torque to make the bolt automatically rotate back to the fully open position, thereby physically inhibiting the bolt from staying in any intermediate position between fully open and half-locked.
[0024] refer to Figure 2 The warning switch assembly refers to an electromechanical sensing unit consisting of a contact structure and a trigger arm (including a top contact). Optionally, the contact structure is fixed to a non-movable part of the lock housing, and the trigger arm is rigidly connected to the lock tongue and rotates synchronously with it. This application outputs different level signals based on the contact / disengagement status of the contact structure and the top contact on the trigger arm, thereby controlling whether to activate the warning.
[0025] The vehicle controller refers to the on-board computing unit with image processing capabilities in the vehicle's electronic and electrical architecture. It is electrically connected to the warning switch assembly to collect level signals in real time and communicates with the external camera to retrieve images of the target door. It performs image analysis, status determination, and alarm command generation, and is the core control node for multi-source information fusion decision-making in this application.
[0026] The lock housing refers to the external rigid shell structure of the door lock assembly, which is used to house and fix all internal parts such as the lock tongue, pivot, spring assembly, and warning switch assembly.
[0027] The fully open position refers to the bolt rotating around the pivot to its extreme position furthest from the latch, at which point the bolt is completely retracted into the lock body and has no possibility of contact with the latch; the half-lock position refers to the bolt initially engaging with the latch during the closing process but not fully in place, at which point the bolt is only partially embedded in the latch groove; the fully locked position refers to the bolt being fully and securely engaged with the latch.
[0028] Specifically, this application ensures that the bolt of the vehicle door lock is maintained and monitored in the fully open position by adding a spring assembly and a warning switch assembly.
[0029] Purpose of the spring assembly: When the latch moves away from the fully open position, the spring assembly is twisted, and the latch will return to the fully open position under the restoring force of the spring assembly.
[0030] Purpose of the warning switch assembly: The warning switch assembly can monitor whether the bolt deviates from the fully open position through on / off signals.
[0031] Central controller: Directly collects the on / off signals of the warning switch component, calls the external camera to acquire and process visual information, and then combines it with the on / off signals of the warning switch component to comprehensively determine whether there is a possibility of false locking of the door. If so, it sends a false lock warning command to the central control display component (such as the central control screen).
[0032] Central control screen: Receives false lock warning commands and displays false lock alarms to users.
[0033] Through the above embodiments, the lock tongue is fundamentally suppressed from lingering in any intermediate position between fully open and half-locked, significantly reducing the risk of lock tongue hovering due to accidental contact, and reducing the physical possibility of false locking from the mechanical source.
[0034] In one embodiment, the level signal includes a first level signal and a second level signal, the second level signal being a target level signal; the warning switch assembly is used to output the first level signal when the bolt is in the fully open position; when the bolt deviates from the fully open position by more than a preset angle threshold, the warning switch assembly outputs the second level signal; when the level signal changes from the first level signal to the second level signal, the vehicle controller is triggered to analyze the target door image to determine the opening and closing state of the target door.
[0035] The target door refers to a specific door that is currently being monitored for the risk of false locks.
[0036] Specifically, the first and second level signals switch freely based on whether the bolt deviates from the fully open position. Understandably, the preset angle threshold can be customized according to actual conditions and application scenarios; for example, the preset angle threshold could be 0°, 5°, etc. The first and second level signals can also be customized according to actual conditions and application scenarios, for example: When the bolt is not moved or the bolt deviates from the fully open position but not beyond the preset angle threshold, the top contact on the trigger arm remains in contact with the contact structure, and the level signal remains the first level signal (on). When the bolt deviates from the fully open position beyond the preset angle threshold, the trigger arm is rotated along with the bolt, and the top contact on the trigger arm disengages from the contact structure, and the level signal switches from the first level signal (on) to the second level signal (off).
[0037] Through the above embodiments, by setting the bolt deviation from the fully open position exceeding a preset angle threshold as the generation condition for the second level signal (target level signal), the abstract abnormal displacement of the bolt is transformed into a calibrable and verifiable physical angle quantity. This avoids false triggering caused by micro-vibrations (overly sensitive) while ensuring timely response (no delay) before a real risk of false locking exists.
[0038] In one embodiment, the warning switch assembly includes a contact structure and a trigger arm. The trigger arm is connected to the latch and rotates synchronously with the latch. When the latch is in the fully open position, the trigger arm is pressed down to the contact structure, causing the warning switch assembly to output a first level signal. When the latch deviates from the fully open position by more than a preset angle threshold, the trigger arm disengages from the contact structure, causing the warning switch assembly to output a second level signal.
[0039] The contact structure refers to the combination of mechanical contact components in the warning switch assembly used to control the circuit's on / off state. When the trigger arm is pressed down, it makes contact with the contact structure to conduct (outputting a first-level signal), and when it is released, it disconnects (outputting a second-level signal). The trigger arm is a slender, lever-shaped mechanical component rigidly connected to the latch body (or latch shaft) and can rotate synchronously with the latch.
[0040] The vehicle will be described below with reference to some specific embodiments: The vehicle includes: a vehicle door lock and a vehicle controller. The vehicle controller is electrically connected to the warning switch assembly and is used to collect the level signal output by the warning switch assembly in real time. When the level signal changes from the first level signal to the second level signal (that is, when the level signal switches to the target level signal, which is the second level signal), the target door image is analyzed to determine the opening and closing status of the target door. When the opening and closing status is open, a false lock warning command is generated.
[0041] Optionally, the vehicle also includes a central control display component, which is used to receive false lock warning commands issued by the vehicle controller and output alarm information to the user based on the false lock warning commands.
[0042] Among them, the central control display component refers to the user-facing main visual output terminal in the vehicle human-machine interaction system, which can be an LCD screen installed in the center console area of the cockpit.
[0043] refer to Figure 3 The following describes the vehicle door lock warning method using specific embodiments. The method includes the following steps: Step S302: When the bolt is not engaged with the latch, the level signal output by the warning switch component is detected in real time. The level signal is used to characterize the position information of the bolt.
[0044] Among them, the level signal refers to the digital electrical signal output by the warning switch assembly, which represents the current mechanical position state of the latch.
[0045] Specifically, during vehicle use, when the latch is not engaged due to accidental contact, vibration, or other reasons, the vehicle controller continuously and frequently acquires the level signal output by the warning switch component through a hard-wired interface. This level signal is a digital signal, and its state is determined by the physical contact relationship between the trigger arm and the contact structure: when the trigger arm presses down on the contact structure, a first level signal (e.g., high level, 3.3 V) is output; when the trigger arm disengages from the contact structure and the deviation angle exceeds a preset angle threshold, a second level signal (e.g., low level, 0 V) is output.
[0046] Through the above embodiments, a level transition can be triggered by the slight displacement of the latch before the door closes or even before the user releases the latch, which greatly advances the warning timing and breaks through the traditional lagging mode that relies on feedback of the switch status after the door is closed.
[0047] Step S304: When the level signal changes from the first level signal to the second level signal, the target door image is acquired. Understandably, when the level signal changes from the first level signal to the second level signal (i.e., when the level signal switches to the target level signal, which is the second level signal), the target level signal is acquired.
[0048] The first level signal refers to the on signal output by the warning switch assembly when the latch is stably in the fully open position and the trigger arm continuously presses down the contact structure.
[0049] The second level signal refers to the off signal output by the warning switch assembly when the latch deviates from the fully open position by more than a preset angle threshold, causing the trigger arm to completely disengage from the contact structure.
[0050] The target door image refers to the external view image of the door to which the warning switch component belongs, which is retrieved and acquired in real time by the vehicle controller after receiving the second level signal transition.
[0051] Specifically, the vehicle controller continuously monitors the level signal output by the warning switch component. When it detects that the level signal changes instantaneously and in a single jump from the first level signal (e.g., high level, indicating that the bolt is in the fully open position) to the second level signal (e.g., low level, indicating that the bolt has deviated from the fully open position by more than a preset angle threshold), the vehicle controller immediately sends an image acquisition command to the external camera corresponding to the target door; triggering the camera to complete image capture in a very short time and send the image data back to the vehicle controller. The above embodiments achieve event-driven image acquisition, that is, image acquisition is started only when the level changes, avoiding the high-power mode of continuous recording and background polling analysis in traditional solutions.
[0052] Step S306: Analyze the target door image to determine the opening and closing status of the target door. When the opening and closing status is open, generate a false lock warning command.
[0053] Among them, the switch status refers to the actual open and closed status determination result of the target door, which is obtained by the vehicle controller based on the target door image analysis, including open status and closed status.
[0054] A false lock warning command is a standardized alarm message with clear door identification and semantics generated by the vehicle controller after confirming that the first level signal has changed to the second level signal and the image analysis determines that the target door is open.
[0055] Specifically, when the warning switch component collects an electrical signal and switches from the first electrical signal (on) to the second electrical signal (off), it calls the external camera to collect the target door image of the corresponding target door. By analyzing the target door image, it determines whether the target door is currently open. If it is open, it indicates that the door lock may be falsely locked. The component then sends a false lock warning command to the central control display component (e.g., the central control screen), triggering the central control display component to output alarm information to the user based on the false lock warning command, prompting the user to check the door lock status.
[0056] Optionally, if the setting is off, the false alarm will be recorded as a log, and the preset angle threshold and preset safety threshold will be adaptively adjusted based on the log content.
[0057] Through the above embodiments, the output of multimodal fusion can accurately identify the possibility of false door locks and further provide early warnings for false door locks, thereby improving vehicle safety.
[0058] In one embodiment, a false lock warning command is sent to the central control display component, triggering the central control display component to output alarm information to the user based on the false lock warning command.
[0059] Among them, alarm information refers to the visual / auditory prompts with clear semantics and human-computer interaction attributes presented to the user by the central control display component after receiving a false lock warning command.
[0060] In one embodiment, step S306, analyzing the target door image to determine the open / closed state of the target door, includes: Based on the target detection model, the system identifies the door edge contour in the target door image; calculates the gap width between the door edge contour and the side of the vehicle body where the door is located; and determines that the door is in the open state when the gap width is greater than a preset safety threshold.
[0061] The target detection model refers to a pre-trained convolutional neural network model suitable for automotive embedded platforms. The input is a single-frame grayscale / RGB image, and the output is a set of pixel-level coordinates of the car door edge contour.
[0062] The door edge contour refers to the closed pixel line that represents the physical boundary of the door, as identified by the target detection model in the target door image. Specifically, it refers to the outer contour line of the side of the door adjacent to the body.
[0063] The side of the vehicle body where the door is located refers to the fixed body structure surface that is hinged to the target door and forms a closing relationship, specifically the door frame area that the door fits against when it is closed.
[0064] The gap width refers to the shortest pixel distance between the edge contour of the car door and the side of the car body where the door is located, measured in the target car door image along a direction perpendicular to the edge contour of the car door.
[0065] The preset safety threshold refers to the physical clearance threshold used to determine whether a car door is in an open state. Understandably, this preset safety threshold can be customized according to actual needs or application scenarios.
[0066] Specifically, after receiving the second-level signal (i.e., the trigger signal indicating that the latch has deviated from the fully open position by more than a preset angle threshold) from the warning switch component, the vehicle controller immediately activates the camera installed on the outside of the vehicle to capture real-time image frames of the area where the target door is located. These image frames are preprocessed by the onboard image processing unit, including grayscale conversion and Gaussian filtering for noise reduction, to enhance edge contrast.
[0067] The vehicle controller then runs a lightweight target detection model to perform end-to-end recognition of the edge contours of the target door in the preprocessed image, outputting the door edge contours. Further, based on the recognized door edge contours and a pre-calibrated vehicle body reference frame, the vehicle controller calculates the minimum vertical gap width between the outermost edge of the door and the adjacent vehicle body structure.
[0068] Finally, the vehicle controller compares the minimum vertical gap width with a preset safety threshold: if the minimum vertical gap width is greater than the preset safety threshold, the target door is determined to be physically open; otherwise, it is determined to be closed.
[0069] Through the above embodiments, the visual judgment result and the level signal form a dual-source verification. Only when the level signal indicates abnormal displacement of the lock tongue and the visual judgment that the door is not actually closed is the false lock warning triggered, which significantly reduces the false alarm rate.
[0070] refer to Figure 4 , Figure 4 This application illustrates the complete early warning process in an embodiment of the present application. The complete early warning process specifically includes: When the passenger door is open (the top contact is pressed down by the trigger arm and makes stable contact with the trigger structure, the voltage level signal is the first level signal "on", indicating that the circuit is connected); when the latch is moved by a child or small animal (the trigger arm rotates with the latch and leaves the contact structure, the voltage level signal is the second level signal "off", indicating that the circuit is disconnected); the vehicle controller recognizes the warning switch status of the passenger door lock through the voltage level signal, which changes from "on" to "off"; it calls the external camera to capture an image of the door status, compares the image with the image, and determines whether the door is closed; if closed, it is considered a normal closing operation; if not closed, the central control screen will issue a warning that the passenger door lock may be falsely locked and suggest reopening the door using the handle or switch.
[0071] Figure 5 A schematic diagram of the framework of a vehicle door lock warning device according to an embodiment of this application is shown. Exemplarily, the vehicle door lock warning device 500 includes: The detection module 502 is used to detect the level signal output by the warning switch component in real time when the bolt is not engaged with the latch. The level signal is used to characterize the position information of the bolt. The acquisition module 504 is used to acquire the target door image when the level signal changes from the first level signal to the second level signal; understandably, when the level signal changes from the first level signal to the second level signal (that is, when the level signal switches to the target level signal, which is the second level signal).
[0072] The analysis module 506 is used to analyze the target door image to determine the opening and closing status of the target door. When the opening and closing status is open, a false lock warning command is generated.
