[0017] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0019] With the development of the automotive industry, consumers' demands for vehicle cabin space are becoming increasingly diversified. In some situations (such as placing large items, needing to rest inside the vehicle, or temporarily converting it into a mobile office space), the existing cabin space layout cannot effectively meet users' space expansion needs.

[0020] Traditional methods for cabin space optimization mostly focus on seat adjustments. For example, when a user wants to place a large item in a certain space, the user needs to adjust the size of that space. This is usually done by actively adjusting the seat position, trying different options as needed to determine if the adjusted space can accommodate the large item. If the large item cannot be placed even after adjusting the seat to its limit, there are no other ways to further optimize the space. This means that existing cabin space optimization strategies cannot meet the actual needs of users.

[0021] Based on this, see Figure 1 This application provides a method for adjusting the vehicle cabin space, executed by a cabin controller, the method specifically including the following steps: Step S100: In response to receiving a cabin space adjustment command, acquire image information inside the vehicle cabin; Step S200: Determine the target object and the target adjustment area based on the image information, and obtain the current spatial information of the target adjustment area and the size information of the target object; Step S300: Based on the current space information and the size information, adjust the vehicle seats and / or fold the steering wheel to increase the space of the target adjustment area.

[0022] Specifically, when a user needs to adjust the cabin space, the user issues a cabin space adjustment command via voice or by clicking on the vehicle's infotainment screen. After receiving the cabin space adjustment command, the cabin controller acquires image information of the vehicle's cabin. The image information includes images of all areas within the vehicle's cabin, and may include images of objects or people currently inside the cabin.

[0023] Based on the image information, the target object and the target adjustment area are determined. The target object is a pre-defined item that occupies a large amount of cabin space, and the target adjustment area is the cabin area that requires space adjustment.

[0024] Specifically, the system acquires the outline and size information of all items in the image. When the outline information of all items is complete, items with a size larger than a first preset size are identified as target objects. This indicates that the target object is completely placed inside the vehicle and has a large size. The purpose of the user issuing a cabin space adjustment command is to adjust the cabin area to change the position of the target object. For example, the target object can be moved from the front row to the back row, or from the back row to the front row.

[0025] In this case, after identifying the target object, the current area is determined based on the target object, and the target adjustment area is determined based on the current area. The target adjustment area and the current area are different areas inside the vehicle. Preferably, the target adjustment area and the current area are different rows of areas inside the vehicle.

[0026] For example, if the current area is the front row area, then the target adjustment area is the back row area; if the current area is the back row area, then the target adjustment area is the front passenger area.

[0027] The first preset size is the maximum size of an item that can be placed inside the vehicle under normal circumstances. When the item's information is larger than the first preset size, it means that the cabin area must be adjusted to accommodate the item.

[0028] Alternatively, if an item has incomplete outline information, its size is larger than the second preset size, and the door of the area where the item is located is open, the item is identified as the target. This indicates that the target is not completely placed in the vehicle, the target is very large, and the user wants to place the item in the vehicle. In this case, the user issues a cabin space adjustment command to adjust the cabin space area so that the target can be placed in the cabin.

[0029] In this case, after identifying the target object, the area where the target object is located is designated as the target adjustment area. For example, if the target object is in the passenger side area, then the passenger side area is designated as the target adjustment area; if the target object is in the left rear seat area, then the left rear seat area is designated as the target adjustment area.

[0030] The second preset size is the maximum size of some items that can be placed inside the vehicle under normal circumstances. When the item's information is larger than the second preset size, it means that the cabin area must be adjusted to accommodate the item.

[0031] After determining the object and the target adjustment area, the current spatial information of the target adjustment area and the size information of the target object are obtained. The current spatial information is the regional spatial information of the target adjustment area in its current state.

[0032] Then, based on the current spatial information and the dimensional information, the vehicle seats are adjusted and / or the steering wheel is folded to increase the space of the target adjustment area. Specifically, only the seats may be adjusted, for example, by adjusting the fore-and-aft position of the seats and the backrest angle, to increase the space of the target adjustment area. Alternatively, the seats and steering wheel may be adjusted simultaneously, by adjusting the fore-and-aft position of the seats and the backrest angle, and folding the steering wheel. In this way, folding the steering wheel can further optimize the cabin space and provide space for further fore-and-aft movement of the seats. Thus, through the combined effect of seat adjustment and steering wheel folding, the space of the target adjustment area can be maximized.

[0033] In this application, upon receiving a cabin space adjustment command, image information of the vehicle cabin is acquired. Based on the image information, a target object and a target adjustment area are determined, and the current spatial information of the target adjustment area and the size information of the target object are acquired. Based on the current spatial information and the size information, the vehicle seats are adjusted and / or the steering wheel is folded. This allows for adjustments to the seat's fore-and-aft position and backrest angle, thereby increasing the space of the target adjustment area. Alternatively, the steering wheel can be folded simultaneously with adjustments to the seat's fore-and-aft position and backrest angle. Thus, this application, when optimizing space, not only adjusts the seat position but also folds the steering wheel associated with the seat, providing space for further fore-and-aft movement of the seat. Through the combined effect of seat adjustment and steering wheel folding, the space of the target adjustment area can be maximized, ensuring that the space optimization meets the user's actual needs.

[0034] In some embodiments, adjusting the vehicle seats and / or folding the steering wheel based on the initially stated spatial information and the size information includes: In response to the current space information being smaller than the size information, the maximum adjustment position of the seat corresponding to the target adjustment area is obtained, and the first adjustment space information of the target adjustment area is determined based on the maximum adjustment position; Based on the first adjustment space information and the size information, the vehicle seats are adjusted and / or the steering wheel is folded.

[0035] Specifically, when adjusting the vehicle's seats and / or folding the steering wheel based on the initially described spatial information and the size information, the size relationship between the current spatial information and the size information is first determined.

[0036] If the current space information is smaller than the size information, it means that the target object cannot be placed within the target adjustment area, and therefore the space of the target adjustment area needs to be adjusted. In this case, the maximum adjustment position of the seat corresponding to the target adjustment area is obtained. This maximum adjustment position is the maximum position that the seat corresponding to the target area can be adjusted to under the current circumstances. For example, if the seat needs to be moved forward to increase the space of the target adjustment area, then the maximum adjustment position is the maximum distance the seat can move forward and / or the maximum angle the seat back can rotate forward. If the seat needs to be moved backward to increase the space of the target adjustment area, then the maximum adjustment position is the maximum distance the seat can move backward and / or the maximum angle the seat back can rotate backward.

[0037] First adjustment space information is determined based on the maximum adjustment position to define the target adjustment area. This first adjustment space information is the spatial dimension information of the target adjustment area after the seat is adjusted to the maximum adjustment position. Based on the first adjustment space information and the dimension information, the vehicle seat is adjusted and / or the steering wheel is folded to ensure that the space of the final adjusted target adjustment area can be used to move the target object.

[0038] In this application, when the current space information is smaller than the size information, the maximum adjustment position of the seat corresponding to the target adjustment area is first obtained. Based on the maximum adjustment position, the first adjustment space information of the target adjustment area is determined. The first adjustment space information thus determined is the space size that the target adjustment area can have after the seat position is adjusted to the limit. Then, based on the first adjustment space information and the size information, the vehicle seat is adjusted and / or the steering wheel is folded to further increase the space size of the target adjustment area as needed, so that the space of the finally optimized target adjustment area can meet the actual needs of the user.

[0039] In some embodiments, adjusting the vehicle seats and / or folding the steering wheel based on the first adjustment space information and the size information includes: In response to the target adjustment area being located in the rear driver's seat area and the first adjustment space information being less than or equal to the size information, the seat position is adjusted to the maximum adjustment position, and the initial folding angle of the steering wheel is obtained, and the steering wheel is folded based on the initial folding angle; Alternatively, in response to the first adjustment space information being greater than the size information, the seat position is adjusted to the maximum adjustment position.

[0040] Specifically, if the first adjustment space information is greater than the size information, it means that after the seat position is adjusted to the maximum adjustment position, the target object can be placed in the target adjustment area. Therefore, there is no need to fold the steering wheel. The seat position can be adjusted directly to the maximum adjustment position. At this time, the target object can be placed in the adjusted target adjustment area by adjusting the seat alone, which meets the user's needs.

[0041] If the target adjustment area is located in the rear driver's area (i.e., the second or third driver's area, etc.), and the first adjustment space information is less than or equal to the size information, it means that even after the seat position is adjusted to the maximum adjustment position, the target object still cannot be placed in the target adjustment area. In this case, the seat position is first adjusted to the maximum adjustment position to increase the space of the target adjustment area by adjusting the seat position.

[0042] Then, the initial folding angle of the steering wheel is obtained, which is the current folding angle of the steering wheel. When the steering wheel is not folded and is in the unfolded state, the current folding angle of the steering wheel is 0°.

[0043] Finally, the steering wheel is folded based on the initial folding angle to further free up cabin space, thereby further increasing the space of the target adjustment area.

[0044] In this application, different adjustment strategies are determined based on different first adjustment space information, thereby maximizing the space of the target adjustment area so that the enlarged target adjustment area can accommodate the target object.

[0045] In some embodiments, folding the steering wheel based on the initial folding angle includes: In response to the initial folding angle not being the preset maximum folding angle, obtain all preset foldable angles of the steering wheel; Based on all the aforementioned preset foldable angles, determine the target foldable angle of the steering wheel and the target movable position of the seat; Fold the steering wheel to the target foldable angle and adjust the seat position to the target movable position.

[0046] Specifically, if the initial folding angle is not the preset maximum folding angle, it means that the steering wheel still has room to fold. In this case, all preset foldable angles of the steering wheel are obtained. The preset foldable angles are the angles at which the steering wheel can still be folded under the current conditions.

[0047] For example, if the initial folding angle is 0°, the preset foldable angle can be 30°, 60°, 90°, etc. If the initial folding angle is 30°, the preset foldable angle can be 60°, 90°, etc.

[0048] Based on all the preset foldable angles, the target foldable angle of the steering wheel and the target movable position of the seat are determined. Then, the steering wheel is folded to the target foldable angle, and the seat position is adjusted to the target movable position. In this way, the cabin space area can be further freed up by folding the steering wheel, thereby providing area support for further movement of the seat. After the steering wheel is folded, the seat position can be moved to further increase the space of the target adjustment area.

[0049] In this application, when the initial folding angle is not the preset maximum folding angle, the cabin space area can be freed up by folding the steering wheel, thereby providing area support for further seat movement. By moving the seat position twice, the cabin space can be optimized to the maximum extent, the space of the target adjustment area can be increased, and the adjusted target adjustment area can be used to place the target object.

[0050] In some embodiments, determining the target folding angle of the steering wheel and the target movable position of the seat based on all the preset folding angles includes: Based on the order of all foldable angles from smallest to largest, the seat movement parameters corresponding to each foldable angle are determined sequentially, and the second adjustment space information of the target adjustment area is determined based on the seat movement parameters. In response to the second adjustment space information being greater than the size information, the seat movement parameter corresponding to the second adjustment space information is determined as the target movable position, and the preset foldable angle corresponding to the target movement parameter is determined as the target foldable angle.

[0051] Specifically, based on the ascending order of all foldable angles, seat movement parameters corresponding to each foldable angle are determined sequentially, and second adjustment space information of the target adjustment area is determined based on the seat movement parameters. The seat movement parameters refer to the positional parameters that allow the seat to move further after the steering wheel is folded at that foldable angle. The second adjustment space information refers to the spatial dimensions of the target adjustment area after the steering wheel is folded and the seat position is further moved.

[0052] If the second adjustment space information is greater than the size information, it means that after adjusting according to the seat movement parameters and preset foldable angle corresponding to the second adjustment space information, the space of the target adjustment area can be used to place the target object. Therefore, the seat movement parameters corresponding to the second adjustment space information are determined as the target movable position, and the preset foldable angle corresponding to the target movement parameters is determined as the target foldable angle. Then, the steering wheel is folded to the target foldable angle, and the seat position is adjusted to the target movable position to ensure that the space of the adjusted target adjustment area can be used to place the target object, thereby optimizing the space of the target adjustment area to meet the user's actual needs.

[0053] In some embodiments, see Figure 2 and Figure 3 As shown, Figure 2 This is a top view of the steering wheel after it has been folded. The white area on the right side of the image represents the space freed up after folding. Before folding, the steering wheel was present in the front area. Figure 2 This is a diagram showing the steering wheel folded in another direction. The right side of the diagram is closer to the seat, and the left side is closer to the front of the car.

[0054] The steering wheel includes a steering wheel body 1, at least two folding shafts 2, a main shaft 3, and a receiving cavity. One end of each of the at least two folding shafts 2 is connected to the main shaft 3, and the other ends of the at least two folding shafts 2 are spaced apart and connected to the steering wheel body 1. The at least two folding shafts 2 are located in the receiving cavity, which is filled with magnetorheological fluid and also equipped with an electromagnetic coil. The at least two folding shafts 2 can rotate around the main shaft 3 to fold or unfold the steering wheel body 1 located between two adjacent folding shafts 2.

[0055] Specifically, magnetorheological fluid is a smart material whose viscosity can change with the applied current and magnetic field force. The greater the applied current and the stronger the magnetic field force, the greater its viscosity, and it can even form a solid material.

[0056] Magnetorheological fluid consists of three parts: Base fluid (such as silicone oil, mineral oil): provides the initial fluid state.

[0057] Micrometer-scale magnetic particles (such as carbonyl iron powder): "active" components that respond to magnetic fields.

[0058] Additives: Prevent particle sedimentation and maintain stability.

[0059] The process works as follows: When an electric current passes through a coil wound around the outside of the magnetorheological fluid container, according to Ampere's law, a magnetic field with a strength proportional to the current is generated. This magnetic field instantly magnetizes the magnetic particles suspended in the base fluid, turning them into tiny magnets. Under the influence of the magnetic field force, these magnetized particles overcome thermal motion and fluid resistance, aligning themselves into chain-like or columnar structures along the magnetic field lines. These chain-like structures act like "bridges," greatly increasing the resistance to fluid flow and thus increasing the viscosity.

[0060] In the zero-current state, without a magnetic field, the magnetic particles are randomly distributed, and the magnetorheological fluid behaves like a typical Newtonian or Bingham fluid, with low viscosity and easy flow. When a small current is applied (generating a weak magnetic field), the particles begin to form weak, sparse chain-like structures, the liquid viscosity begins to increase, and the yield stress is very small. As the current increases and the magnetic field strengthens, the magnetization force between the particles increases sharply (proportional to the square of the magnetic field strength), and the chain-like structures become more numerous, coarser, and stronger. The yield stress of the liquid increases significantly, manifested as a sharp increase in viscosity. When the current increases to a certain extent, almost all the magnetic particles are fully arranged into chains, the structural strength reaches its limit, and the viscosity also reaches its limit, essentially forming a solid structure. Further increases in current no longer significantly increase the yield stress, indicating magnetic saturation.

[0061] Therefore, before reaching magnetic saturation, the viscosity of the magnetorheological fluid increases rapidly with increasing current, and is usually non-linear, eventually reaching saturation.

[0062] The state changes of magnetorheological fluids are extremely rapid, typically occurring within milliseconds. Once the current is cut off, the magnetic field disappears, the magnetization of the particles vanishes, and the chain-like structure rapidly disintegrates under the influence of thermal motion and the base fluid, instantly restoring the magnetorheological fluid to its low-viscosity state. Therefore, by precisely adjusting the input current, its viscosity can be continuously and linearly controlled, thereby achieving stepless adjustment of the damping force.

[0063] In this application, at least two of the folding shafts 2 are located within the receiving cavity, which is filled with magnetorheological fluid and also contains an electromagnetic coil. Therefore, by controlling the current applied to the electromagnetic coil, the magnetic field generated by the electromagnetic coil can be adjusted, and the viscosity of the magnetorheological fluid can be adjusted based on the change in the magnetic field.

[0064] When the applied current is very small, the viscosity of the magnetorheological fluid is very small and the fluidity is very strong. At this time, the presence of the magnetorheological fluid will not affect the rotation of the folding shaft 2. The folding shaft 2 can rotate around the main shaft 3. The rotation of the folding shaft 2 can cause the steering wheel body 1 located between two adjacent folding shafts 2 to fold or unfold.

[0065] For example, see Figure 2 As shown, when located Figure 2 When the upper folding shaft 2 rotates in the direction shown by A, the steering wheel body 1 located between the two folding shafts 2 can be folded. The folded steering wheel body 1 can release space near the seat, thereby providing space for further movement of the seat.

[0066] When located Figure 2 When the upper folding shaft 2 is rotated in the direction shown by B, the steering wheel body 1 located between the two folding shafts 2 can be released. After being released, the steering wheel body 1 can gradually return to its original shape, making it convenient for the driver to use later.

[0067] When the applied current is large, the viscosity of the magnetorheological fluid is very high and its fluidity is very poor, almost turning into a solid material. At this time, the presence of the magnetorheological fluid will restrict the rotation of the folding shaft 2, causing the folding shaft 2 to be unable to rotate around the main shaft 3, thereby limiting the folding shaft 2 and quickly restricting it to the required position, thus ensuring the accuracy and reliability of the steering wheel folding.

[0068] In this application, the rotation and stopping of the folding shaft 2 are controlled by controlling the viscosity of the magnetorheological fluid. By utilizing the material properties of the magnetorheological fluid, the rotation and stopping of the folding shaft 2 are controlled quickly and accurately, thereby enabling the steering wheel to be folded quickly and accurately, improving the flexibility and simplicity of steering wheel folding.

[0069] In some embodiments, see continue to see Figure 2 and Figure 3 As shown, folding the steering wheel to the target foldable angle includes: The current intensity applied to the electromagnetic coil is controlled to reduce the viscosity of the magnetorheological fluid; Control the folding shaft 2 to rotate around the main shaft 3, so that the steering wheel body 1 located between two adjacent folding shafts 2 folds; Get the steering wheel folding angle in real time; In response to the folding angle reaching the target foldable angle, the current intensity applied to the electromagnetic coil is increased to a level greater than or equal to a preset intensity to increase the viscosity of the magnetorheological fluid, thereby stopping the rotation of the folding shaft 2.

[0070] Specifically, the current intensity applied to the electromagnetic coil is controlled to reduce the viscosity of the magnetorheological fluid; further, the current intensity applied to the electromagnetic coil is reduced to reduce the viscosity of the magnetorheological fluid.

[0071] Then, the folding shaft 2 is controlled to rotate around the main shaft 3, so that the steering wheel body 1 located between two adjacent folding shafts 2 is folded, and the folding angle of the steering wheel is obtained in real time.

[0072] When the folding angle reaches the target foldable angle, it indicates that the steering wheel folding angle has met the requirements. The current intensity applied to the electromagnetic coil is increased to a level greater than or equal to a preset intensity to increase the viscosity of the magnetorheological fluid, causing the magnetorheological fluid to form a solid structure. The solid structure of the magnetorheological fluid blocks and limits the folding shaft 2, causing the folding shaft 2 to stop rotating.

[0073] In this application, the viscosity of the magnetorheological fluid is adjusted by controlling the current intensity applied to the electromagnetic coil, thereby controlling the rotation and stopping of the folding shaft 2. By utilizing the material properties of the magnetorheological fluid, the rotation and stopping of the folding shaft 2 are quickly and accurately controlled, thus enabling the steering wheel to be folded quickly and accurately, improving the flexibility and simplicity of steering wheel folding.

[0074] In some embodiments, see Figure 4 The bottom of the seat is provided with a seat slide rail 4, and the seat slide rail 4 is provided with a first shape memory alloy wire 5. One end of the first shape memory alloy wire 5 is fixed to the seat slide rail 4, and the other end is fixed to the bottom of the seat. The first shape memory alloy can drive the seat to slide along the seat slide rail 4 under heating conditions.

[0075] Specifically, the deformation principle of shape memory alloys is based on the reversible transformation of the internal microstructure of the crystal between two different phases—namely, the transformation between the martensite and austenite phases. This process is called thermoelastic martensitic transformation, which involves two key crystal phases: (1) Austenitic parent phase Temperature: Stable at higher temperatures.

[0076] Crystal structure: It is usually a highly symmetrical, regular cubic lattice (e.g., B2 or L21 structure).

[0077] Characteristics: This phase is where the alloy's "shape memory" is located. It has high strength but is relatively hard.

[0078] (2) Martensitic phase Temperature: Stable at lower temperatures.

[0079] Crystal structure: A distorted lattice with low symmetry (e.g., a monoclinic lattice). This phase transition is not achieved through atomic diffusion, but through overall shear deformation of the crystal structure.

[0080] Key characteristics: Thermoelasticity and twinning. Thermoelasticity refers to the low interfacial energy barrier between the martensite and austenite phases, allowing temperature changes to drive the phase interface to move back and forth, much like a spring. Twinning refers to the fact that the martensite formed at low temperatures is not a single crystal, but rather composed of many variants. These variants are like pieces of a puzzle. Figure 1 These twins fit together harmoniously, forming "twinned martensite." Macroscopically, this twinned structure cancels each other out, resulting in no net deformation of the alloy as a whole.

[0081] The principle of the shape memory effect of shape memory alloys will be explained in detail below: Step 1: Memorize the shape of the master image (initial state) Alloys are processed into the desired "memory shape" (such as a straight wire) at high temperatures (austenitic state), at which point their crystal structure is a regular cubic lattice.

[0082] Step 2: Cooling and Martensitic Phase Transformation When the alloy is cooled to below a certain critical temperature (the temperature at which the martensitic phase transformation begins) until the phase transformation is complete, it will transform from austenite to martensite. This martensite is self-cooperative twinned martensite, and its macroscopic shape remains unchanged (the filaments are still straight).

[0083] Step 3: Deformation at low temperatures This occurs in the martensitic state. At this stage, the alloy is very soft and easily deformable (pseudoelastic). When a small external force is applied, the following microscopic process occurs: the interface between the different oriented martensitic variants (twins) begins to move. Those martensitic variants that are more adapted to the direction of the external force "absorb" the other variants. Eventually, almost all the martensitic variants align uniformly along the direction of the external force, forming "detwinned martensite".

[0084] Macroscopic manifestation: The alloy exhibits huge, seemingly permanent plastic deformation (like bending a straight wire into a circle). However, this "plasticity" is essentially a crystallographic reorientation, rather than the permanent damage caused by dislocation slip in traditional metals.

[0085] Step 4: Heating and Restoring the Shape This is the most remarkable step: when the deformed alloy is heated above a certain critical temperature (the temperature at which the austenitic phase transformation begins) until the phase transformation is complete, the reverse phase transformation occurs. The detwinned martensite becomes unstable, and the crystal structure begins to recover towards the highly symmetric austenitic parent phase. Since austenite has only one unique crystal orientation (i.e., the orientation corresponding to the initially memorized shape), during the phase transformation, atoms strictly follow the memorized path back to their original positions.

[0086] Macroscopic manifestation: The alloy has completely recovered to the original shape set in the first step (the circle has turned back into a straight line), and the previous huge deformation seems to have been "forgotten".

[0087] External forces induce a phase transformation from austenite to martensite (stress-induced martensite). This martensite is also detwinized, leading to macroscopic deformation. Once the external force is removed, the martensite becomes unstable and immediately reverses to austenite, restoring the material to its original state.

[0088] The "deformation" of shape memory alloys is a reversible reconstruction in crystallography, while the plastic deformation of traditional materials is an irreversible accumulation of defects (dislocations). This is the fundamental reason why shape memory alloys can "remember" shapes.

[0089] In this application, a first shape memory alloy wire 5 is provided on the seat slide rail 4. Specifically, the first shape memory alloy wire 5 is located on the inner side of the seat slide rail 4. One end of the first shape memory alloy wire 5 is fixed to the seat slide rail 4, and the other end is fixed to the bottom of the seat. When the first shape memory alloy is not heated, it is in the martensitic crystal phase. After heating, the crystal orientation of the first shape memory alloy wire 5 gradually changes from martensite to austenite. Its macroscopic manifestation is that the first shape memory alloy wire 5 gradually changes to its initial state (i.e., the shape of the memory parent phase), thereby driving the seat to slide along the seat slide rail 4 to realize the adjustment of the seat position.

[0090] The initial state of the first shape memory alloy wire 5 is the state of the first shape memory alloy when the steering wheel is folded to the preset maximum folding angle and the seat is moved forward to the limit position.

[0091] Therefore, as the first shape memory alloy wire 5 gradually transforms into its initial state (i.e., the shape of the memory master phase), it can drive the seat to move along the seat slide rail 4 towards the front of the vehicle, thereby further increasing the space of the target adjustment area.

[0092] In this application, by utilizing the memory properties of the first shape memory alloy, the movement or stopping of the seat can be precisely controlled based on whether the first shape memory alloy wire 5 is heated or not, without the need for additional structures, thus improving the flexibility and accuracy of seat control.

[0093] In some embodiments, the maximum adjustment position includes a maximum movement position; adjusting the seat position to the maximum adjustment position includes: The first shape memory alloy wire 5 is heated so that the first shape memory alloy wire 5 drives the seat to slide along the seat slide rail 4; Get the current position of the seat in real time; In response to the current position reaching the maximum movement position, heating of the first shape memory alloy wire 5 is stopped to stop moving the seat.

[0094] Specifically, an electric current is applied to the first shape memory alloy wire 5, thereby heating the first shape memory alloy wire 5. As a result, the crystal phase of the first shape memory alloy begins to change, and the first shape memory alloy wire 5 gradually transforms back to its initial state (i.e., the shape of the memory master phase). This allows the seat to move along the seat slide rail 4 towards the front of the vehicle.

[0095] During this process, the current position of the seat is acquired in real time. When the current position reaches the maximum moving position, it indicates that the seat position has been moved to the maximum moving position and there is no need to continue moving the seat. Therefore, heating of the first shape memory alloy wire 5 is stopped to stop driving the seat to move.

[0096] In this application, the memory properties of the first shape memory alloy are utilized. When the first shape memory alloy wire 5 is needed to move the seat, an electric current is applied to the first shape memory alloy wire 5 to heat it. When the first shape memory alloy wire 5 is not needed to move the seat, the electric current is stopped to stop heating the first shape memory alloy wire 5. In this way, the movement or stopping of the seat can be precisely controlled simply by controlling whether the first shape memory alloy wire 5 is heated or not, without the need for additional structures, thus improving the flexibility and accuracy of seat control.

[0097] In some embodiments, see continue to see Figure 4 The seat includes a backrest 8 and a base 6. A pivot 7 is provided at the connection between the backrest 8 and the base 6. A second shape memory alloy wire (not shown in the figure) is provided inside the pivot 7. The second shape memory alloy wire can drive the pivot 7 to rotate under heating conditions, so as to drive the backrest 8 to rotate relative to the base 6.

[0098] Specifically, the second shape memory alloy is in the martensitic crystal phase when it is not heated. After heating, the crystal orientation of the second shape memory alloy wire gradually changes from martensite to austenite. The macroscopic manifestation is that the second shape memory alloy wire gradually changes back to its initial state (i.e., the shape of the memory parent phase), which in turn drives the backrest 8 to rotate relative to the base 6.

[0099] The initial state of the second shape memory alloy wire is the state of the second shape memory alloy when the seat back 8 is rotated to its extreme position near the front of the vehicle.

[0100] Therefore, as the second shape memory alloy wire gradually transforms back to its initial state (i.e., the shape of the memory master phase), it can drive the backrest 8 to rotate relative to the base 6 towards the front of the vehicle, thereby further increasing the space of the target adjustment area.

[0101] In this application, by utilizing the memory properties of the second shape memory alloy, the backrest 8 can be precisely controlled to rotate or stop based on whether the second shape memory alloy wire is heated or not, without the need for additional structures, thus improving the flexibility and precision of seat control.

[0102] In some embodiments, the maximum adjustment position includes the maximum adjustment angle; Adjusting the seat position to the maximum adjustment position includes: The second shape memory alloy wire is heated so that the second shape memory alloy wire causes the backrest 8 to rotate relative to the base 6; Get the current angle of the backrest 8 in real time; In response to the current angle reaching the maximum adjustment angle, heating of the second shape memory alloy wire is stopped to stop the backrest 8 from rotating.

[0103] Specifically, heating the second shape memory alloy wire causes it to gradually transform back to its initial state (i.e., the shape of the memory master phase), which in turn drives the backrest 8 to rotate relative to the base 6 towards the front of the vehicle.

[0104] During this process, the current angle of the backrest 8 is acquired in real time. When the current angle reaches the maximum adjustment angle, it indicates that the backrest 8 has been adjusted to the maximum angle. At this time, by rotating the backrest 8, the maximum available space has been released, and the heating of the second shape memory alloy wire is stopped to stop driving the backrest 8 to rotate.

[0105] In this application, the memory properties of the second shape memory alloy are utilized. When the second shape memory alloy wire is needed to rotate the backrest 8, an electric current is applied to the second shape memory alloy wire to heat it. When the second shape memory alloy wire is not needed to rotate the backrest 8, the electric current is stopped to stop heating the second shape memory alloy wire. In this way, the rotation or stopping of the backrest 8 can be precisely controlled simply by controlling whether the second shape memory alloy wire is heated or not. No extra structure is required, which improves the flexibility and accuracy of seat control.

[0106] It is worth noting that the entire implementation process of this application was carried out under the premise that the vehicle was stationary and there was no driver in the driver's seat, thus ensuring the safety of the vehicle.
