Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and particularly to a sill device for a vehicle, a method for operating a sill device, a computer program product, and a corresponding vehicle. Background Art

[0002] With the rapid development of the automotive industry, people have put forward higher and higher requirements for the comfort and convenience of vehicles. For example, during the use of a vehicle by an occupant, the occupant needs to frequently enter and exit the vehicle compartment, and it is inevitable to touch the sill area of the vehicle when getting on and off the vehicle. However, during the driving of the vehicle, the rotation of the wheels easily splashes pollutants such as mud and dust on the road surface onto the body surface, especially the sill area. When the door is opened and the occupant gets out of the vehicle, clothes such as trouser legs or skirts are extremely likely to scrape against the contaminated sill area, resulting in the clothes being soiled, bringing inconvenience and trouble to the occupant, and affecting the occupant's experience of using the vehicle.

[0003] Therefore, there is still a practical need for continuous improvement in the aspect of the sill area of the vehicle. Summary of the Invention

[0062] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the scope of protection of the present invention, and that various embodiments may share the same view or multiple views for description, but all features appearing in the same view cannot be interpreted as features that must be possessed by an embodiment.

[0063] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0064] Figure 1 A schematic perspective view of a vehicle 2000 according to an embodiment of the present invention is shown, and an xyz coordinate system of the vehicle 2000 is exemplarily provided, wherein the x-axis represents the longitudinal direction of the vehicle 2000, the y-axis represents the lateral direction of the vehicle 2000, and the z-axis represents the height direction of the vehicle 2000. For the sake of clarity, the following drawings are basically referred to as Figure 1 The xyz coordinate system shown is displayed and described. Figure 2 1 is a schematic perspective view showing a door sill device 1000 for a vehicle 2000 in a first working state P1 according to an embodiment of the present invention.

[0065] like Figure 1 As shown, the vehicle 2000 has a door sill device 1000, and the door sill device 1000 is installed at the side door sill of the vehicle 2000. Here, the vehicle 2000 is preferably configured as a high chassis vehicle such as an off-road vehicle or an SUV (Sports Utility Vehicle). Figure 1 Only one door sill device 1000 is schematically shown in the figure, but it should be understood that a door sill device 1000 according to an embodiment of the present invention is preferably configured in each door sill area for getting on and off the vehicle.

[0066] like Figure 2As shown schematically, the threshold device 1000 includes a threshold body 900 and a shielding assembly 800. The threshold body 900 can be fixedly connected to the vehicle body 2001 of the vehicle 2000 by bolts or welding, for example, to form a basic structural part of the side of the vehicle. In the scope of the present invention, the term "fixed connection" should be understood as a connection between two components in a manner that cannot move relative to each other. The shielding assembly 800 is an independent structure relative to the threshold body 900 (see also the following description). Figure 3 ), the shielding assembly 800 is connected to the door sill body 900 and includes at least two movable parts: a first part 100 and a second part 200. The first part 100 is exemplarily configured as a middle cover plate in the figure, which has a first outer side 110 facing the outside of the vehicle; the second part 200 is exemplarily configured as an upper cover plate in the figure, which has a second outer side 210 facing upward. Both parts can move relative to the door sill body 900, thereby constituting the main movable part of the shielding assembly 800. The door sill device 1000 has a contact area that the occupants may contact when getting on and off the vehicle, and has three different working states: in the first working state P1, as shown Figure 2 As will be described below Figures 3 to 17 As shown, the door sill device 1000 is in a default normal state, at which the first outer side 110 of the first component 100 and the second outer side 210 of the second component 200 are both exposed to the outside, forming an area that the occupant may touch. The two outer side surfaces are preferably flush with the original vehicle door sill to maintain the industrial aesthetics of the vehicle. In the second working state P2, as will be described below, Figures 20 to 23 As shown, this can be understood as the first mode of the door sill device 1000, the second component 200 is turned over and put into the first component 100 or moved in other ways so that the second outer side 210 of the second component 200 is no longer included in the passenger's contact area. At this time, when the passenger gets off the vehicle, he will not touch the second outer side 210 that may be contaminated. In the third working state P3, as will be described below Figures 24 to 26 As shown, this can be understood as the second mode of the threshold device 1000, in which the first component 100 is turned over and unfolded downward or the first outer side 110 of the first component 100 is no longer included in the passenger's contact area through other movement methods. This third working state P3 of forming a pedal is particularly suitable for situations where there is water on the ground or the vehicle has a large ground clearance. Therefore, by changing the working state of the threshold device 1000, the passenger's clothes can be effectively prevented from being soiled by the threshold contaminants, and at the same time, a convenient pedal function is provided when needed, which improves the passenger's experience of getting on and off the vehicle.

[0070] As Figure 2 combined with Figures 3 to 7 shown, the shielding assembly 800 may further include a third component 300 in addition to the first component 100 and the second component 200. The third component 300 is exemplarily configured as a lower fixing plate in the drawings, and may be configured as a base portion of the entire shielding assembly 800. Combined with Figure 13 and Figure 14 , the third component 300 may be fixedly connected to the sill body 900 by a plurality of fixing bolts 302, for example. In an embodiment not shown, when the shielding assembly 800 does not include the third component 300, the first component 100 may be configured to be movably connected to the sill body 900 (i.e., the third component 300 is integrated into the sill body 900). In the embodiment shown in the drawings, the third component 300 is preferably made of high-strength plastic or metal, and thus has sufficient rigidity and strength to be able to bear the weight of the entire shielding assembly 800 and the pressure generated when an occupant steps on it (especially see the third working state P3 and the fourth working state P4 shown in Figures 24 to 29 ).

[0071] As Figures 3 to 5 shown, the first component 100 is connected to the third component 300 by a first rotating shaft 10. The first rotating shaft 10 is preferably a bearing structure that penetrates the entire first component 100, made of high-strength plastic or metal, and preferably undergoes special treatment to improve wear resistance and strength. Both ends of the first rotating shaft 10 are respectively installed in the bearing seats provided on the third component 300 to allow the first component 100 to rotate freely around the first rotating shaft 10. To ensure the smoothness and accuracy of the rotation of the first component 100, the first rotating shaft 10 is preferably connected to Figure 12The micro motor 11 shown schematically is, for example, a stepper motor design, which can accurately control the rotation angle to drive the first component 100 to rotate smoothly. The motor 11 can be connected to the vehicle power supply and control system via a waterproof connector to ensure reliable operation in harsh environments. The first component 100 is configured to be able to pivot about 0° to 90° around the first rotating shaft 10 relative to the third component 300. Upon receiving a control signal, the motor 11 drives the first rotating shaft 10 to rotate, driving the first component 100 to flip outward from the first working state P1 or the second working state P2 (both are basically vertical positions) to a preset angle, forming an outwardly extending pedal (see in particular the pedal to be described). Figures 24 to 29 To prevent excessive rotation, the shielding assembly 800 is also provided with a mechanical limit mechanism and an electronic limit control mechanism to ensure that the first component 100 can only rotate within a preset angle range to avoid damage to the shielding assembly 800 or safety hazards caused by excessive rotation.

[0072] like Figures 3 to 5 As shown, the second component 200 is connected to the first component 100 via a second rotating shaft 20. The second rotating shaft 20 is preferably a pair of independent shaft structures, respectively located at the two ends of the second component 200, and is also made of high-strength plastic or metal, preferably specially treated to improve wear resistance and strength. The difference from the first rotating shaft 10 is that the second rotating shaft 20 can be constructed as a continuous shaft that does not run through the entire second component 200, but is independently arranged at its two ends. This design is conducive to reducing weight and simplifying the internal structure.

[0073] like Figure 4 As shown, the first component 100 has a first inner side 120 opposite to the first outer side 110 and two opposite side edges 140 connecting the first outer side 110 and the first inner side 120. The two opposite side edges 140 are respectively provided with sliding grooves 141 for the two ends of the second rotating shaft 20 to slide therein. Figure 4 It can be seen that the two ends of the second rotating shaft 20 are respectively inserted into the slide grooves 141 on the two opposite side edges 140. These slide grooves 141 are linear, and their width is slightly larger than the diameter of the rotating shaft. One side of the slide groove 141 is preferably provided with a rack structure not specifically shown, and the end of the second rotating shaft 20 is equipped with a pinion gear not specifically shown that meshes with it, for example, through Figure 10 The motor 21 shown schematically drives the gear to rotate by forward rotation, so that the second shaft 20 can move up and down in the slide slot 141. The second component 200 is configured to be able to pivot around the second shaft 20 relative to the first component 100. Figure 21 and Figure 25 As shown, the first component 100 is designed as a hollow structure having an internal cavity 130, and the internal cavity 130 is large enough to accommodate the second component 200 (inFigure 21 and Figure 25 are both schematically shown by dashed lines). When the threshold device 1000 switches from the first working state P1 to the second working state P2, the motor 21 first drives the second component 200 to rotate around the second rotating shaft 20 to the intermediate state P0 as shown in Figure 18 . Then, through the meshing action of the gear and the rack, the second rotating shaft 20 is driven to move downward along the chute, so that the second component 200 is received into the inner cavity 130 of the first component 100. To ensure the stability of the pivoting process, the second rotating shaft 20 preferably adopts a double-bearing design, reducing the rotational friction and improving the motion accuracy. At the same time, the motor 21 adopts encoder feedback control, which can accurately control the rotation angle and speed to ensure smooth and coherent actions. The entire pivoting process is uniformly controlled by the vehicle-mounted ECU, and corresponding action sequences can be executed according to different scenario requirements.

[0074] As Figure 2 , Figure 18 and Figure 20 show, the threshold device 1000 has a clear intermediate state P0 between the first working state P1 and the second working state P2. In the intermediate state P0 as shown in Figure 18 and Figure 19 , the second component 200 is basically in the vertical direction and stands above the first component 100. This configuration is achieved by the precise controlled rotation of the second component 200 around its horizontal axis (i.e., the second rotating shaft 20). The rotational motion is powered by the motor 21 to ensure a smooth transition and prevent sudden movements that may cause mechanical stress or passenger discomfort. The vertical positioning of the second component 200 in the intermediate state P0 has multiple functional purposes: First, this enables the reorientation of the second component 200 in preparation for the subsequent vertical descent into the inner cavity 130 of the first component 100; Second, this configuration reduces the horizontal occupied space in the deployed state, minimizing potential interference to surrounding passengers or objects during the conversion process; Third, this provides a short time for the entire threshold device 1000 to verify correct alignment before proceeding to the next stage of the conversion sequence. In the first working state P1, as Figure 9 and Figure 10The electromagnetic limit block 22 shown ensures unnecessary slippage of the second component 200. Then, after the second component 200 pivots to the intermediate state P0, it is activated electromagnetically (e.g., retracting the electromagnetic limit block 22) to release the movement of the second component 200 towards the second working state P2. Optionally, the electromagnetic limit block 22 can also temporarily fix the vertical position of the second component 200 during the intermediate state P0 to ensure stability before the entire threshold device 1000 is ready to transition to the second working state P2. Thus, these limit blocks 22 can prevent the second component 200 from experiencing unnecessary gravitational drops before the entire threshold device 1000 is ready. It should be understood, however, that the intermediate state P0 is inherently transient and typically only exists for a moment in the transition sequence. It is not a stable operating configuration designed for passenger interaction because the vertically placed second component 200 may impede passenger movement. Instead, it is a necessary transitional stage for achieving complex folding and retraction movements, which is what differentiates this threshold device from traditional fixed designs. In another embodiment, the second component 200 can also transition from the intermediate state P0 to the second working state P2 solely by gravity to reduce excessive control costs.

[0075] To achieve Figures 20 to 23 the second working state P2 shown, after the second component 200 rotates around the second rotation axis 20 to the intermediate state P0, it slides downward along the sliding grooves 141 on the two opposing side edges 140 of the first component 100 and finally completely retracts into the internal cavity 130 of the first component 100. At this time, the second component 200 is completely hidden inside the first component 100, and the second outer side 210 of the second component 200 cannot be seen or touched from the outside.

[0076] To achieve Figures 24 to 26 the third working state P3 shown, it can be achieved through the pivoting action of the first component 100. As described above, in the second working state P2, the second component 200 has already retracted into the internal cavity 130 of the first component 100, and at this time the first component 100 is still in a substantially vertical state. To transition from the second working state P2 to the third working state P3, the control system, for example, sends a start signal to the motor 11 connected to the first rotation axis 10. After the motor 11 is started, it drives the first rotation axis 10 to rotate, causing the first component 100 to flip downward around the first rotation axis 10. The first component 100 gradually rotates from its initial substantially vertical position to a position nearly parallel to the third component 300, forming an outwardly extending platform structure. Preferably, the first component 100 maintains a certain inclination angle with the ground, and this design is intended to facilitate the flow of foreign substances such as water stains that may accumulate on the first component 100 along the inclined first component 100.

[0077] From Figure 4It can be seen that the first component 100 has two main surfaces: one is a first outer side 110 facing the outside of the vehicle, and the other is a first inner side 120 opposite thereto. In the normal first working state P1, the first outer side 110 is flush with the rocker body 900 in appearance, while the first inner side 120 faces the rocker body 900 and is invisible. Figures 24 to 26 In the third working state P3 shown, the first component 100 is flipped about 90 degrees, so that the first inner side 120 originally facing the door sill body 900 turns upward and becomes part of the passenger contact area. At this time, the first inner side 120 forms a relatively flat surface for passengers to step on. The surface design of the first inner side 120 can take into account the anti-slip requirements, and preferably adopts texture treatment or special material coating to enhance friction and improve the safety of passengers when stepping on it.

[0078] Similarly, from Figure 4 It can also be seen that the second component 200 has a second inner side 220 opposite to the second outer side 210 facing upward. In the normal first working state P1, the second inner side 220 faces the threshold body 900 and is invisible. The surface treatment of the second inner side 220 is similar to that of the first inner side 120, and adopts an anti-slip design and wear-resistant materials. The threshold device 1000 also has the following Figures 27 to 29 The fourth working state P4 shown can be achieved from the third working state P3 by translating the second component 200, or from the intermediate state P0 by directly pivoting the first component 100 together with the second component 200. It can be understood that the first component 100 and the second component 200 have the same relative positional relationship with each other in the fourth working state P4 as in the intermediate state P0.

[0079] from Figure 15 Combination Figure 2It can be seen that the third component 300 is provided with a ground environment detector 301 on the side facing the ground, which is used to detect the environmental data of the ground where the vehicle 2000 is located. The ground environment detector 301 can be composed of a variety of sensing elements: for example, an ultrasonic distance sensor can be used to sense the ground distance; or an infrared moisture detector can be used to use the near-infrared reflection principle to detect the difference in reflectivity of infrared rays of different wavelengths to determine whether there is water on the ground and the depth of the water; or an image sensor can be used in conjunction with an image processing algorithm to identify ground conditions, such as water, mud, snow, etc. When the vehicle 2000 stops and the door is opened, the ground environment detector 301 can be automatically started, collect ground environment data and transmit it to the on-board ECU for analysis. The on-board ECU determines the current ground condition according to the preset algorithm, and decides whether to activate the corresponding working mode of the threshold device 1000 accordingly, so as to provide the occupants with the most suitable boarding and alighting assistance for the current environment. This ground environment detection design enables the threshold device 1000 to intelligently perceive the surrounding environment, actively adapt to the needs of different scenarios, and improve the intelligence level of the system and user experience.

[0080] In some special cases, for example, when the ground environment detector 301 detects that the road surface has a large waterlogged area and the first component 100 cannot completely cover the waterlogged area after being unfolded (third working state P3), the threshold device 1000 may enter the fourth working state P4. Figures 27 to 29 As shown, in the fourth working state P4, the first component 100 has been turned outward and unfolded, and the second component 200 that has been received in the internal cavity 130 of the first component 100 in the third working state P3, for example, extends out from the inside of the first component 100 through the reverse action of the motor 21. The specific process is: the motor 21 runs in the reverse direction, and the gear meshes with the rack on the slide groove, driving the second shaft 20 to move out along the slide groove 141, so that the second inner side 220 faces upward and forms a basically continuous plane with the first inner side 120. In this state, the second inner side 220 and the first inner side 120 together constitute an extended contact area, and the second inner side 220 becomes an extension of the pedal. As a result, the effective length of the entire pedal is increased, which can cover a larger range of ground area, provide a longer stepping area for passengers, and is particularly suitable for situations where the roadside water is large. This expandable design enables the threshold device to more flexibly cope with various complex environments, further improving the practicality of the device and the convenience of passengers getting on and off the vehicle.

[0081] like Figure 3 , Figure 24 and Figure 26As shown, at least one (preferably multiple, spaced apart and parallel) groove 121 is provided on the first inner side 120 of the first component 100. These grooves 121 are in the form of linear groove structures, and their main function is to guide the fluid out of the threshold device 1000 and increase the friction of the first inner side 120 in the third working state P3 and / or the fourth working state P4. In the third working state P3, the first component 100 is turned outward and unfolded, and its first inner side 120 faces upward to form a pedal. At this time, the groove 121 plays a role of guiding the fluid, such as rainwater and mud, which may fall on the pedal surface to the outside of the threshold device 1000. The overall design of the groove 121 is slightly inclined, with a slight slope from the inside to the outside (for example, about 1° to 5°), to ensure that the fluid can flow out smoothly without accumulating inside the device. This design effectively utilizes the effect of gravity, so that the water naturally flows to the gap 101 between the first component 100 and the third component 300 and then flows out of the threshold device 1000 from the bottom. If the threshold device 1000 enters the fourth working state P4, that is, the second component 200 is also unfolded to form an extended pedal, the groove 121 continues to play a diversion role, and cooperates with a similar structure (such as the same groove structure) that may be provided on the second inner side 220 of the second component 200 to form a continuous drainage channel. The design of this groove not only takes into account the drainage function, but also takes into account the anti-skid effect. The edge of the groove is finely processed to avoid the wear and tear of the sole caused by sharp corners. At the same time, the presence of the groove increases the roughness of the pedal surface and improves the friction coefficient, especially under wet conditions, which can effectively prevent the occupants' feet from slipping. This design enables the threshold device 1000 to provide a clean and safe stepping area for the occupants in the third working state P3 and / or the fourth working state P4, effectively solving the problem of difficulty for the occupants to get on and off the vehicle in rainy and snowy weather or when the vehicle has a large ground clearance, and at the same time avoids the risk of the occupants' clothes getting dirty due to contact with the outer surface of the threshold that may be contaminated.

[0082] like Figure 3 , Figure 24 , Figure 26 , Figure 27 and Figure 29As shown, the first component 100 is provided with a light-emitting member 122 on the first inner side 120, which is an integrated lighting system, for example, it can be composed of the following parts: high-brightness LED lamp beads, a light-transmitting cover, a control circuit and a waterproof sealing structure. The light-emitting member 122 is preferably arranged at the edge of the first inner side 120 as shown in the figure, and can also be distributed in a strip shape, surrounding the pedal area. The main function of the light-emitting member 122 is to indicate the position of the pedal area in the third working state P3 and / or the fourth working state P4. When the threshold device 1000 is in the unfolded state, especially at night or in a low-light environment, the light-emitting member 122 can automatically light up to provide clear visual guidance for the occupants, help them accurately identify the position and boundary of the pedal, and avoid safety risks caused by improper stepping.

[0083] from Figure 2 , Figure 20 , Figure 24 and Figure 27 It can be seen that the sill body 900, as part of the side structure of the vehicle, has a vertical front side 910 facing outward. This vertical front side 910 constitutes a part of the lower part of the side of the vehicle, which is originally an area that is easily touched by passengers when getting on and off the vehicle. The surface of the vertical front side 910 is usually finely processed to coordinate with the overall style of the vehicle body, and may be painted with a paint surface of the same color as the vehicle body or special decorative materials. The sill body 900 also has a first recessed portion 911 that is recessed relative to the vertical front side 910. The shape of the first recessed portion 911 is preferably matched with the outer contour of the first component 100 to accommodate the first component 100 so that it can be flush with the vertical front side 910 of the sill device 1000 in the first working state P1. Similarly, the sill body 900 has an inclined upper side 920 at its upper part, which originally constitutes an area that is easily touched by passengers when getting on and off the vehicle. The sill body 900 also has a second recessed portion 921 that is recessed relative to the inclined upper side 920. The shape of the second recess 921 matches the outer contour of the second component 200 to accommodate the second component 200 so that it is flush with the inclined upper side 920 of the threshold device 1000 in the first working state P1. The first recess 911 and the second recess 921 can be formed, for example, by a stamping process of the threshold body 900 itself. This recessed design ensures that in the normal state of the threshold device 1000 (i.e., the first working state P1), the appearance of the vehicle basically maintains the original design, and there is no protruding part that destroys the overall aesthetics. At the same time, the flush design also avoids the potential safety hazards caused by the protruding parts.

[0084] Figure 30 FIG. 3 is a schematic flow chart of an operating method 3000 for a threshold device 1000 according to an embodiment of the present invention. Figure 30 As shown, the operating method 3000 for the door sill device 1000 exemplarily includes steps S100 and S200 .

[0085] In step S100, the surface cleanliness information of the shielding component 800 in the contact area is obtained. The method may be, for example, by Figure 1 The vehicle 2000 shown schematically has a detection device 2003 (e.g., a camera or millimeter wave radar equipped with an algorithm) installed on the side of its door 2002 facing the threshold device 1000 to detect the surface cleanliness data of the shielding component 800. Optionally, the occupant can also manually input the relevant surface cleanliness information, for example, when the occupant has determined or is concerned that there are contaminated components in the contact area, the switching of the working state can be triggered, for example, by the vehicle-mounted ECU.

[0086] In step S200, the corresponding working state of the threshold device 1000 is set according to the surface cleanliness information obtained. Here, the vehicle-mounted ECU can determine whether the surface cleanliness exceeds the preset threshold value according to the detection result of the analysis detection device 2003. For example, by comparing with the pre-stored reference threshold area image (for example, an uncontaminated threshold area image) and / or a regular graphic image (for example, a regular printed image), when the newly added feature relative to the reference image is an irregular shape, and the newly added irregular shape feature area accounts for more than 20% of the monitored area, it is determined that there is a relatively large area of ​​stains. Here, if it is determined that the second outer side 210 of the second component 200 is seriously contaminated and the first outer side 110 of the first component 100 is relatively clean, an instruction is issued to switch the threshold device 1000 to the second working state P2, for example, by activating the motor 21 to flip the second component 200 and put it into the first component 100. If it is determined that the first outer side 110 of the first component 100 is seriously contaminated, or both the first outer side 110 and the second outer side 210 are seriously contaminated, an instruction is issued to switch the threshold device 1000 to the third working state P3, for example, by activating the motor 11 and the motor 21 to retract the second component 200 into the first component 100 and unfold the first component 100 to form a pedal structure.

[0087] Figure 31 A schematic flow chart of an operating method 3000 for a door sill device 1000 according to an embodiment of the present invention is shown. In addition to steps S100 and S200, the operating method 3000 exemplarily further includes steps S110, S111, S210, and S112.

[0088] In step S100, the information of the upcoming passenger boarding and alighting behavior of the vehicle 2000 is obtained. Here, for example, the passenger's intention to board and alight can be predicted by a variety of signals. For judging the passenger's intention to board the vehicle, the system can monitor the following signals: vehicle remote control key unlocking signal, key proximity signal, vehicle exterior handle touch sensor signal or mobile phone APP remote unlocking command, etc. To prevent misoperation, when any signal is detected, the time interval with the last operation can be further calculated. If the interval exceeds the set time (usually 15 minutes), it is determined to be a new boarding event. For judging the passenger's intention to get off the vehicle, the following signals can be monitored: vehicle P gear signal, engine shutdown signal, vehicle stop moving signal, seat belt unfastening signal, passenger movement detection signal in the vehicle (for example, through infrared sensor or seat pressure sensor, etc.). When multiple signals that meet the conditions are detected (for example, at least 2 to 3 items can be required to be met at the same time), it is determined that the passenger has the intention to get off the vehicle.

[0089] In step S111, when the obtained passenger boarding and alighting behavior information indicates that a passenger is about to board the vehicle, the environmental data of the ground where the vehicle 2000 is located is detected. Here, for example, when it is determined that a passenger is about to board the vehicle, the ground environment detector 301 on the third component 300 can be immediately activated. After the ground environment detector 301 is started, it starts to collect environmental data of the ground where the vehicle 2000 is located, which may include, for example, the ground water situation and the height of the door sill from the ground. The data collected by the ground environment detector 301 can be transmitted to the vehicle-mounted ECU after preprocessing (such as filtering, average value calculation, etc.). After receiving the data, the vehicle-mounted ECU can apply a specific algorithm to calculate key environmental parameters, such as the percentage of the water accumulation area, the depth of the water accumulation, the actual height from the ground, etc.

[0090] In step S210, when the detected environmental data exceeds the preset conditions, the threshold device 1000 is switched to the third working state P3. Here, for example, the threshold height from the ground can be set to 400 mm. When this preset condition or other preset conditions (such as the presence of accumulated water, etc.) are exceeded, it is determined that the current environment requires pedal assistance. Then, an instruction can be immediately issued to activate the conversion mechanism (such as the motor 11, the motor 21, and the electromagnetic limit block 22, etc.), and the threshold device 1000 can be switched from the first working state P1 or the second working state P2 to the third working state P3. During the switching process, it can be further determined whether it is necessary to expand to the fourth working state P4 based on the severity of the data. For example, if the accumulated water area is particularly large (for example, more than half of the accumulated water area is not covered), it can be directly switched to the fourth working state P4 to provide the largest pedal area.

[0091] In step S112, when the obtained passenger boarding and alighting behavior information indicates that a passenger is about to get off the vehicle, step S100 is executed. When it is determined that a passenger is about to get off the vehicle, the detection device 2003 can be immediately activated and step S100 is started to obtain the surface cleanliness information of the shielding component 800. Then, the standard decision-making process is entered to select the appropriate working state according to the pollution situation.

[0092] Therefore, this operation method based on the prediction of passenger behavior enables the threshold device to prepare in advance and provide timely assistance to the passengers, improving the system's response speed and user experience. At the same time, by distinguishing between boarding and getting off the vehicle, the system can adopt more targeted response strategies.

[0093] In an embodiment not shown, step S100 of the operation method 3000 may be specifically step S101 and / or step S102, and step S200 may be specifically step S201 and / or step S202.

[0094] In step S101, the surface cleanliness data of the second outer side 210 of the second component 200 in the contact area is detected. Here, when the cleanliness detection process is triggered, the detection focus can first be set on the second outer side 210 of the second component 200, that is, the upper surface area of ​​the door sill. The detection device 2003 can capture high-resolution images of the area to ensure that fine stains can be identified. The captured image can be processed in multiple stages, for example: first, Gaussian filtering is applied to reduce noise, then an adaptive threshold segmentation algorithm is used to extract potential stain areas, then the extraction results are optimized through morphological operations (such as opening and closing operations), and finally a contour analysis algorithm is applied to distinguish between regular and irregular shape features. Here, it is preferred to calculate the percentage of the total area of ​​irregular shape features (i.e., potential stains) in the visible area of ​​the second outer side 210 as the cleanliness data of the second outer side 210.

[0095] In step S201, when the surface cleanliness data of the second outer side 210 of the second component 200 exceeds the second outer side cleanliness threshold, the threshold device 1000 is switched to the second working state P2. Here, the calculated second outer side cleanliness data can be compared with the preset second outer side cleanliness threshold. The second outer side cleanliness threshold can be set to, for example, 20% of the area. When this threshold is exceeded, it is determined that the second outer side 210 is seriously polluted. Preferably, if the second outer side 210 is seriously polluted and the first outer side 110 of the first component 100 is not detected to be seriously polluted (that is, the detection result of step S102 does not exceed the threshold), an instruction is issued to switch the threshold device 1000 to the second working state P2.

[0096] In step S102, the surface cleanliness data of the first outer side 110 of the first component 100 in the contact area is detected. Here, the first outer side 110 of the first component 100, that is, the side area of ​​the door sill, can be detected after or at the same time as step S101. The detection and analysis process is similar to step S101, but since the first outer side 110 is basically a vertical surface, it is preferred to adjust the direction parameters and lighting compensation in the image processing algorithm to ensure the detection accuracy. The cleanliness data of the first outer side 110 can also include the area ratio of irregular shape features, and the calculation method is similar to that of the second outer side 210.

[0097] In step S202, when the surface cleanliness data of the first outer side 110 of the first component 100 exceeds the first outer side cleanliness threshold, the threshold device 1000 is switched to the third working state P3. Here, the cleanliness data of the first outer side 110 can be compared with the preset first outer side cleanliness threshold. The first outer side cleanliness threshold can be set to 20% of the area, for example. If the cleanliness data of the first outer side 110 exceeds this threshold, regardless of the cleanliness status of the second outer side 210, an instruction can be issued to switch the threshold device 1000 to the third working state P3. To this end, for example, the motor 21 can be controlled to operate, the second component 200 can be put into the first component 100, and then the first component 100 can be driven to flip outward around the first rotating shaft 10 to form a pedal structure.

[0098] Therefore, this refined decision-making process based on multi-zone cleanliness data enables the threshold device to make the most appropriate working state selection according to the pollution conditions of different parts, thereby improving the overall intelligence and adaptability of the threshold device.
