Description

Technical Field

[0001] The present invention relates to the technical field of vehicle seat control, and in particular to a vehicle seat adjustment method, device and vehicle. Background Art

[0002] At present, with the development of vehicle functional technology, the requirements for full utilization of vehicle interior space and intelligent control of vehicle seats are becoming increasingly higher. In the prior art, there are often other components around vehicle seats. When the vehicle seats are adjusted to the extreme position, they often interfere with the surrounding components, which will lead to poor seat adjustment experience for users. In addition, the interior space of the vehicle is irregular. Under the condition of vehicle interior space limitation, the adjustable range of the vehicle seats is small and the interior space of the vehicle cannot be fully utilized. Summary of the invention

[0003] Based on this, it is necessary to provide a vehicle seat adjustment method, device and vehicle to address the above technical problems, so as to solve technical problems in the prior art such as vehicle seat adjustment is prone to interfere with surrounding components.

[0004] A vehicle seat adjustment method, comprising:

[0005] receiving a first seat adjustment instruction including a first adjustment direction, and determining first Hall position information of the vehicle seat at a next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction;

[0006] When the first adjustment direction includes at least one of the preset interference directions, determining whether the vehicle seat reaches a preset interference position at the next adjustment moment according to the first Hall position information;

[0007] When the preset interference position is not reached, obtaining a first limit position corresponding to the first adjustment direction;

[0008] When it is determined according to the first preset Hall position information that the vehicle seat has not reached the first limit position at the next adjustment moment, the first seat adjustment instruction is executed.

[0009] A vehicle seat adjustment device, comprising:

[0010] a receiving module, configured to receive a first seat adjustment instruction including a first adjustment direction, and determine first Hall position information of the vehicle seat at a next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction;

[0011] a determination module, configured to determine, when the first adjustment direction includes at least one of the preset interference directions, whether the vehicle seat reaches a preset interference position at a next adjustment moment according to the first Hall position information;

[0012] An acquisition module, configured to acquire a first limit position corresponding to the first adjustment direction when the preset interference position is not reached;

[0013] An execution module is used to execute the first seat adjustment instruction when it is determined according to the first preset Hall position information that the vehicle seat has not reached the first limit position at the next adjustment moment.

[0014] A vehicle comprises a vehicle seat and a control module communicatively connected to the vehicle seat, wherein the control module is used to execute the above-mentioned vehicle seat adjustment method.

[0015] In the above-mentioned vehicle seat adjustment method, device and vehicle, the method includes: receiving a first seat adjustment instruction including a first adjustment direction, determining the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction; when the first adjustment direction includes at least one of the preset interference directions, determining whether the vehicle seat reaches the preset interference position at the next adjustment moment according to the first Hall position information; when the preset interference position is not reached, obtaining the first limit position corresponding to the first adjustment direction; when it is determined according to the first preset Hall position information that the vehicle seat does not reach the first limit position at the next adjustment moment, executing the first seat adjustment instruction.

[0016] After the present invention determines the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction, if it is determined that the first adjustment direction includes at least one of the preset interference directions, at this time, continuing to move in the first adjustment direction may reach the preset interference position and interfere with surrounding components. Therefore, after the present invention determines that the vehicle seat has not reached the preset interference position at the next adjustment moment according to the first Hall position information, it will further judge whether it will reach the first extreme position corresponding to the first adjustment direction at the next adjustment moment. In this way, the subsequent seat adjustment process is always based on the premise that there will be no interference with surrounding components, thereby avoiding interference between the vehicle seat and surrounding components during the adjustment process and improving the user experience. Furthermore, the present invention executes the first seat adjustment instruction to specifically adjust the seat in the first adjustment direction (the first adjustment direction may be at least one direction) only after determining that the vehicle seat will not reach the first limit position at the next adjustment moment, thereby avoiding the motor continuing to run and causing stalling after the vehicle seat reaches the limit position. In this way, the service life is improved while the user experience is further improved. Moreover, through the control strategy of the above-mentioned vehicle seat adjustment method, the position limiting function of the vehicle seat in the whole vehicle scenario can be realized (the vehicle seat will not be adjusted to reach the preset interference position or the first limit position), and there is no need to install other hardware on the vehicle to optimize the seat adjustment process, thereby saving costs. In the present invention, when it is determined that the preset interference position and the first limit position have not been reached at the next adjustment moment, the seat can be arbitrarily adjusted in different first adjustment directions, thereby making more effective use of the interior space of the vehicle.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] In one embodiment, if Figure 1 As shown, a vehicle seat adjustment method is provided, comprising the following steps S10-S40:

[0023] S10. Receive a first seat adjustment instruction including a first adjustment direction, and determine the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction; wherein the first seat adjustment instruction can be sent to the control module when the user triggers the adjustment switch on the vehicle seat, or can be entered and sent to the control module through the vehicle's display interface or voice instruction information; the control module is installed on the vehicle, and the control module can be a seat controller, a domain controller, a vehicle controller, etc.

[0024] It is understandable that the vehicle seat in the present invention can be adjusted from multiple adjustable directions, and the first adjustment direction in the first seat adjustment instruction (and the second adjustment direction in the second seat adjustment instruction mentioned later) are one or more of the above adjustable directions. That is, a seat adjustment instruction (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.) can include one or more adjustable directions, so that the vehicle seat can be adjusted from one or more directions when the seat adjustment instruction is finally executed. The preset interference direction is part of the above adjustable directions, and the continuous movement of the vehicle seat along any preset interference direction may interfere with the surrounding components; all directions except the preset interference direction in all adjustable directions are non-interference directions, that is, even if the vehicle continues to move to the extreme position along the non-interference direction, it will not interfere with the surrounding components. It is understandable that the above first adjustment direction or the second adjustment direction may include a preset interference direction and / or a non-interference direction.

[0025] In one embodiment, the preset interference direction includes the seat rail backward movement direction, the seat height downward movement direction and the seat back backward rotation direction, a total of 3 preset interference directions; the adjustable direction includes the seat rail backward movement direction, the seat rail forward movement direction, the seat height downward movement direction, the seat height upward movement direction, the seat back backward rotation direction and the seat back forward rotation direction, a total of 6 adjustable directions. At this time, the non-interference direction is the seat rail forward movement direction, the seat height upward movement direction and the seat back forward rotation direction, a total of 3 non-interference directions.

[0026] In this embodiment, the first slide rail drive motor installed on the vehicle is used to drive the vehicle seat to move along the rearward movement direction of the seat slide rail and the forward movement direction of the seat slide rail; the back adjustment drive motor is used to drive the vehicle seat to move along the downward movement direction of the seat height adjustment and the upward movement direction of the seat height adjustment; the height adjustment drive motor is used to drive the vehicle seat to move along the rearward rotation direction of the seat back and the forward rotation direction of the seat back; furthermore, through the above three drive motors, the overall posture control of the vehicle seat can be completed together; and the above three drive motors (back adjustment drive motor, height adjustment drive motor and first slide rail drive motor) are all drive motors with Hall chips, which can realize power output and memory functions; the three drive motors are all connected to the control module in communication, and the control module can control the three drive motors to execute adjustment instructions (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.) to realize multi-dimensional adjustment of the vehicle seat in the above 6 adjustable directions.

[0027] Furthermore, the preset interference direction also includes the leftward movement direction of the seat slide and the rightward movement direction of the seat slide; the adjustable direction also includes the leftward movement direction of the seat slide and the rightward movement direction of the seat slide. At this time, there are also three non-interference directions, namely, the forward movement direction of the seat slide, the upward movement direction of the seat height adjustment, and the forward rotation direction of the seat backrest. The preset interference direction includes the backward movement direction of the seat slide, the downward movement direction of the seat height adjustment, the backward rotation direction of the seat backrest, the leftward movement direction of the seat slide, and the rightward movement direction of the seat slide, for a total of five preset interference directions; the adjustable directions include the backward movement direction of the seat slide, the forward movement direction of the seat slide, the downward movement direction of the seat height adjustment, the upward movement direction of the seat height adjustment, the backward rotation direction of the seat backrest, the forward rotation direction of the seat backrest, the leftward movement direction of the seat slide, and the rightward movement direction of the seat slide, for a total of eight adjustable directions.

[0028] In this embodiment, in addition to the above three drive motors (back adjustment drive motor, height adjustment drive motor and first slide rail drive motor), a second slide rail drive motor is also included for driving the vehicle seat to move along the seat slide rail to the left and the seat slide rail to the right. In this embodiment, the second slide rail drive motor is also a drive motor with a Hall chip, which can realize power output and memory functions; the second slide rail drive motor is connected to the control module for communication, and the control module can control the second slide rail drive motor, the back adjustment drive motor, the height adjustment drive motor and the first slide rail drive motor to execute adjustment instructions (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.), thereby realizing multi-dimensional adjustment of the vehicle seat in the above 8 adjustable directions.

[0029] Furthermore, the preset interference direction also includes the seat zero-gravity rearward angle adjustment direction; the adjustable direction also includes the seat zero-gravity forward angle adjustment direction and the seat zero-gravity rearward angle adjustment direction. At this time, the preset interference direction includes the seat zero-gravity rearward angle adjustment direction, the seat slide backward movement direction, the seat high-profile downward movement direction and the seat backrest backward rotation direction, a total of 4 preset interference directions; the adjustable direction includes the seat zero-gravity forward angle adjustment direction, the seat zero-gravity rearward angle adjustment direction, the seat slide backward movement direction, the seat slide forward movement direction, the seat high-profile downward movement direction, the seat high-profile upward movement direction, the seat backrest backward rotation direction and the seat backrest forward rotation direction, a total of 8 adjustable directions. At this time, the non-interference direction is the seat slide forward movement direction, the seat high-profile upward movement direction and the seat backrest forward rotation direction. The non-interference directions are the seat zero-gravity forward angle adjustment direction, the seat slide forward movement direction, the seat high-profile upward movement direction and the seat back forward rotation direction. Compared with the previous embodiment, one seat zero-gravity forward angle adjustment direction is added, for a total of four non-interference directions. This is because when the vehicle seat moves toward the seat zero-gravity forward angle adjustment direction, it will not interfere with the surrounding components in front.

[0030] In this embodiment, a back adjustment drive motor, a height adjustment drive motor and a first slide rail drive motor are arranged around the vehicle seat, and a zero gravity angle adjustment motor is used to drive the vehicle seat to move along the seat zero gravity forward angle adjustment direction and the seat zero gravity backward angle adjustment direction. In this embodiment, the zero gravity angle adjustment motor is also a drive motor with a Hall chip, which can realize power output and memory functions; the zero gravity angle adjustment motor is connected to the control module, and the control module can control the zero gravity angle adjustment motor, the back adjustment drive motor, the height adjustment drive motor and the first slide rail drive motor to execute adjustment instructions (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.), thereby realizing multi-dimensional adjustment of the vehicle seat in the above 8 adjustable directions.

[0031] Furthermore, the preset interference direction also includes the leftward movement direction of the seat rail, the rightward movement direction of the seat rail, and the zero-gravity rearward angle adjustment direction of the seat; the adjustable direction also includes the leftward movement direction of the seat rail, the rightward movement direction of the seat rail, the forward zero-gravity angle adjustment direction of the seat, and the backward zero-gravity angle adjustment direction of the seat. That is, the preset interference direction includes the backward movement direction of the seat rail, the downward movement direction of the seat high-profile, the backward rotation direction of the seat backrest, the leftward movement direction of the seat rail, the rightward movement direction of the seat rail, and the backward zero-gravity angle adjustment direction of the seat, a total of 6 preset interference directions; the adjustable direction includes the backward movement direction of the seat rail, the forward movement direction of the seat rail, the downward movement direction of the seat high-profile, the upward movement direction of the seat high-profile, the backward rotation direction of the seat backrest, the forward rotation direction of the seat backrest, the leftward movement direction of the seat rail, the rightward movement direction of the seat rail, the forward zero-gravity angle adjustment direction of the seat, and the backward zero-gravity angle adjustment direction of the seat, a total of 10 adjustable directions. At this time, the non-interference directions are the forward movement direction of the seat slide, the upward movement direction of the seat, the forward rotation direction of the seat back and the forward angle adjustment direction of the seat in zero gravity, a total of 4 non-interference directions.

[0032] In this embodiment, a back adjustment drive motor, a height adjustment drive motor, a first slide rail drive motor, a second slide rail drive motor, and a zero gravity angle adjustment motor are arranged around the vehicle seat. The control module can control the above five drive motors to execute adjustment instructions (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.), thereby realizing multi-dimensional adjustment of the vehicle seat in the above 10 adjustable directions.

[0033] It should be noted that since the rearward movement direction of the seat slide and the forward movement direction of the seat slide are a set of reverse adjustable directions, the downward movement direction of the seat high-adjustment and the upward movement direction of the seat high-adjustment are a set of reverse adjustable directions, the rearward rotation direction of the seat back and the forward rotation direction of the seat back are a set of reverse adjustable directions, the leftward movement direction of the seat slide and the rightward movement direction of the seat slide are a set of reverse adjustable directions, and the forward zero-gravity angle adjustment direction of the seat and the rear zero-gravity angle adjustment direction of the seat are a set of reverse adjustable directions; therefore, in the same adjustment instruction (such as the first seat adjustment instruction or the second seat adjustment instruction, etc.), only one of the adjustable directions in each group of reverse adjustable directions can be included (and two reverse adjustable directions in a group cannot be included at the same time).

[0034] In one embodiment, the initial Hall position information includes Hall number information associated with all adjustable directions of the vehicle seat at the current moment; understandably, since the movement of the vehicle seat in each adjustable direction is adjusted by a drive motor with a Hall chip, the Hall number corresponding to the adjustment parameter (such as distance or rotation angle) of the vehicle seat in the adjustable direction can be determined by the Hall chip. In this embodiment, the Hall number information after the last vehicle seat adjustment stored in the control module is called, which is the initial Hall position information corresponding to the current position at the current moment; understandably, at the current position of the vehicle seat at the current moment, each adjustable direction will correspond to a Hall number information; understandably, the Hall number information corresponding to the two adjustable directions in the same group of reverse adjustable directions is the same.

[0035] Further, in step S10, determining the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information and the first adjustment direction includes:

[0036] S101, obtaining the Hall adjustment speed corresponding to each of the first adjustment directions, and the time difference between the next adjustment moment and the current moment; understandably, after selecting the drive motors for each adjustable direction of the vehicle seat, the Hall adjustment speed corresponding to the adjustable direction has been determined. Therefore, it is only necessary to determine which adjustable directions are included in the first adjustment direction, and the Hall adjustment speeds corresponding to these adjustable directions can be determined accordingly. At the same time, the time difference between the next adjustment moment and the current moment can be pre-set according to demand, such as set to 1 second.

[0037] S102, update the Hall number information corresponding to each of the first adjustment directions in the initial Hall position information according to the time difference and the obtained Hall adjustment speeds, and record the updated initial Hall position information as the first Hall position information of the vehicle seat at the next adjustment moment. That is, in the above initial Hall position information, the Hall number information corresponding to each of the first adjustment directions is updated according to the corresponding time difference and Hall adjustment speed (and because the Hall number information corresponding to the two adjustable directions in the same group of reverse adjustable directions must be the same, the other adjustable direction belonging to the same group of reverse adjustable directions as the above first adjustment directions will also be updated synchronously), and other Hall number information will not be changed, and all the Hall number information updated and not updated is recorded together as the first Hall position information of the vehicle seat at the next adjustment moment.

[0038] S20, when the first adjustment direction includes at least one of the preset interference directions, determining whether the vehicle seat reaches a preset interference position at the next adjustment moment according to the first Hall position information;

[0039] Understandably, since the continuous movement of the vehicle seat along any preset interference direction may interfere with the surrounding components, when the first adjustment direction includes at least one of the preset interference directions, it means that the vehicle seat is adjusted according to the first seat adjustment instruction, that is, it is possible to interfere with the surrounding components; and since the preset interference position refers to the critical position where the vehicle seat will interfere with the surrounding components during the adjustment process; therefore, when the vehicle seat reaches the preset interference position at the next adjustment moment, it means that the vehicle will immediately interfere with the surrounding components at the current moment, so it is not suitable to move at this time (since the preset interference position is at the critical point, in order to maintain a sufficient gap with the surrounding components, the vehicle seat is preferably not to reach the preset interference position). When the vehicle seat does not reach the preset interference position at the next adjustment moment, it means that the vehicle will not interfere with the surrounding components even if it continues to move. Therefore, after further determining in the subsequent steps that the vehicle seat does not reach the first limit position at the next adjustment moment, the first seat adjustment instruction can be executed to adjust the vehicle seat. Among them, the preset interference position can refer to all position points in the preset fitting interference interface obtained by fitting processing. The above fitting process may include: firstly calibrating the coordinates of a plurality of interference position points according to the actual vehicle, or determining the coordinates of a plurality of interference position points according to the data simulation results obtained by simulating the actual vehicle; and then, according to the above interference position point coordinates (such as Figure 3 The coordinate list is generated by using the interference position point coordinates S shown in , and then the preset fitting model and the preset fitting interference interface corresponding to the preset fitting model are fitted by using software such as matlab. The preset fitting model can be a simplified polynomial. When the polynomial is equal to 0, it means that the interference distance between the vehicle seat and the preset fitting interference interface is equal to zero (that is, the vehicle seat reaches the preset interference position). Figure 3 The F shown in is the preset fitting interference interface, and any point in the preset fitting interference interface F can be regarded as a preset interference position.

[0040] S30. When the preset interference position is not reached, the first limit position corresponding to the first adjustment direction is obtained; it is understandable that each adjustable direction of the vehicle seat corresponds to an extreme coordinate position (in the present invention, the extreme coordinate position can be converted into a Hall number in advance to facilitate subsequent comparison). When the vehicle seat moves along the adjustable direction to the extreme coordinate position, even if the drive motor corresponding to the adjustable direction continues to run, the vehicle seat will not continue to move, and may cause the drive motor to be blocked. The above-mentioned first limit position is a set of extreme coordinate positions corresponding to each different first adjustment direction. In this embodiment, when it is determined that the preset interference position has not been reached, it means that the vehicle seat will not interfere with the surrounding components at the next adjustment moment, but it cannot be determined whether the vehicle seat has reached the extreme coordinate position corresponding to each first adjustment direction. Therefore, it is necessary to first obtain the first limit position corresponding to the first adjustment direction, and then enter step S40 for further processing.

[0041] S40. When it is determined according to the first preset Hall position information that the vehicle seat has not reached the first limit position at the next adjustment moment, the first seat adjustment instruction is executed. It can be understood that at the next adjustment moment, when the vehicle seat reaches the corresponding limit coordinate position in at least one first adjustment direction (the limit coordinate position can be determined by comparing the limit coordinate position with the latest Hall number information corresponding to the first adjustment direction in the first preset Hall position information), it means that the vehicle seat will reach the first limit position at the next adjustment moment; and when the vehicle seat does not reach the corresponding limit coordinate position in all first adjustment directions, it means that the vehicle seat has not reached the first limit position at the next adjustment moment. At this time, the above-mentioned first seat adjustment instruction can be directly executed, that is, the vehicle seat is controlled to move along the first adjustment direction until a stop instruction is received, or it is detected that the vehicle seat reaches the preset interference position or a certain limit coordinate position at the next adjustment moment, and the execution of the first seat adjustment instruction can be stopped.

[0042] After the present invention determines the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction, if it is determined that the first adjustment direction includes at least one of the preset interference directions, at this time, continuing to move in the first adjustment direction may reach the preset interference position and interfere with surrounding components. Therefore, after the present invention determines that the vehicle seat has not reached the preset interference position at the next adjustment moment according to the first Hall position information, it will further judge whether it will reach the first extreme position corresponding to the first adjustment direction at the next adjustment moment. In this way, the subsequent seat adjustment process is always based on the premise that there will be no interference with surrounding components, thereby avoiding interference between the vehicle seat and surrounding components during the adjustment process and improving the user experience. Furthermore, the present invention executes the first seat adjustment instruction to specifically adjust the seat in the first adjustment direction (the first adjustment direction may be at least one direction) only after it determines that the vehicle seat will not reach the first limit position at the next adjustment moment, thereby avoiding the motor continuing to run and causing stalling after the vehicle seat reaches the limit position. In this way, the service life is improved while the user experience is further improved. In the present invention, when it is determined that the preset interference position and the first limit position have not been reached at the next adjustment moment, the seat can be arbitrarily adjusted in different first adjustment directions, thereby making more effective use of the interior space of the vehicle.

[0043] The present invention is based on the hardware configuration of the existing vehicle seats, and executes the above-mentioned vehicle seat adjustment method through control of the control module. In this way, through the control strategy of the above-mentioned vehicle seat adjustment method, the limiting function of the vehicle seat in the whole vehicle scenario can be realized (it will not be adjusted to reach the preset interference position or the first limit position), avoiding the installation of other hardware on the vehicle to optimize the seat adjustment process, and saving costs; at the same time, the present invention can achieve adaptive matching for the complex environments in which different vehicle seats are located by replacing and adjusting the preset interference position, and the adjustable direction in the present invention is changeable, and can also be increased or decreased according to needs, thereby realizing the realization of a comprehensive limiting function with more functions, and has wide applicability.

[0044] In one embodiment, in step S20, determining whether the vehicle seat reaches a preset interference position at the next adjustment moment according to the first Hall position information includes:

[0045] S201, obtain the Hall number information corresponding to each of the preset interference directions from the first Hall position information, and determine the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment based on all the Hall number information obtained; that is, in this embodiment, the interference distance can be obtained by the preset fitting model obtained by fitting in the above step S20. In this step, the Hall number information obtained is not the Hall number information corresponding to the first adjustment direction in the first Hall position information, but the Hall number information corresponding to each of the preset interference directions in the first Hall position information; it can be understood that if there are two preset interference directions belonging to the same group of reverse adjustable directions, it is only necessary to obtain one Hall number information corresponding to the group of reverse adjustable directions, and there is no need to repeatedly obtain two identical Hall number information.

[0046] S202, when the interference distance is greater than zero, it is determined that the vehicle seat has not reached the preset interference position at the next adjustment moment; specifically, when the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment is greater than zero, it means that the vehicle seat has not reached the preset interference position at the next adjustment moment, and therefore the vehicle seat can still be adjusted at the current moment.

[0047] S203, when the interference distance is less than or equal to zero, determining that the vehicle seat will reach the preset interference position at the next adjustment moment. Specifically, when the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment is less than or equal to zero, it indicates that the vehicle seat will reach the preset interference position at the next adjustment moment, and therefore the vehicle seat cannot be adjusted further at the current moment.

[0048] In one embodiment, the preset interference direction includes a seat slide backward movement direction, a seat height downward movement direction, and a seat back backward rotation direction; the step S201, i.e., obtaining Hall number information corresponding to each of the preset interference directions from the first Hall position information, and determining the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment according to all the acquired Hall number information, includes:

[0049] From the first Hall position information, obtain the first slide rail Hall number corresponding to the rearward movement direction of the seat slide rail, the first high-profile Hall number corresponding to the downward movement direction of the seat high-profile, and the first backrest Hall number corresponding to the rearward rotation direction of the seat backrest; wherein, the first slide rail Hall number is the Hall number information of the next adjustment moment corresponding to the rearward movement direction of the seat slide rail in the first Hall position information; the first high-profile Hall number is the Hall number information of the next adjustment moment corresponding to the downward movement direction of the seat high-profile in the first Hall position information; the first backrest Hall number is the Hall number information of the next adjustment moment corresponding to the rearward rotation direction of the seat backrest in the first Hall position information.

[0050] The first slide rail Hall number, the first high-profile Hall number and the first backrest Hall number are input into a preset fitting model to obtain an interference distance between the vehicle seat and a preset fitting interference interface at the next adjustment moment.

[0051] In one embodiment, the preset fitting model is:

[0052] f(h1,s1,b1)=p0+p1*h1+p2*s1+p3*h1*s 1+p4*h1^2+p5*s1^2-b1

[0053] in:

[0054] f(h1, s1, b1) is the interference distance between the vehicle seat and the preset fitting interference interface;

[0055] h1 is the first high-profile Hall number; wherein h1=h0+V[height]*△t; h0 is the Hall number information corresponding to the seat high-profile downward movement direction in the initial Hall position information; V[height] is the Hall adjustment speed of the height adjustment drive motor corresponding to the seat high-profile downward movement direction; △t is the time difference between the next adjustment moment and the current moment;

[0056] s1 is the Hall number of the first slide rail; wherein s1=s0+V[slider]*△t; s0 is the Hall number information corresponding to the backward movement direction of the seat slide rail in the initial Hall position information; V[slider] is the Hall adjustment speed of the first slide rail drive motor corresponding to the backward movement direction of the seat slide rail;

[0057] b1 is the first backrest Hall number; wherein b1=b0+V[back]*△t; h0 is the Hall number information corresponding to the rearward rotation direction of the seat back in the initial Hall position information; V[height] is the Hall adjustment speed of the back adjustment drive motor corresponding to the rearward rotation direction of the seat back;

[0058] p0 is the first fitting coefficient;

[0059] p1 is the second fitting coefficient;

[0060] p2 is the third fitting coefficient;

[0061] p3 is the fourth fitting coefficient;

[0062] p4 is the fifth fitting coefficient;

[0063] p5 is the sixth fitting coefficient.

[0064] It can be understood that the above-mentioned p0, p1, p2, p3, p4, and p5 are all constant values.

[0065] Specifically, after the first rail Hall number s1, the first high-profile Hall number h1, and the first backrest Hall number b1 are input into the preset fitting model, if the obtained interference distance f(h1, s1, b1)>0, it means that the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment is greater than zero; and if the obtained interference distance f(h1, s1, b1)≤0, it means that the interference distance between the vehicle seat and the preset fitting interference interface at the next adjustment moment is less than or equal to zero. In this embodiment, the three Hall number information is used to judge the interference distance, so that the movable space corresponding to the extreme coordinate position of the vehicle seat and all the above adjustable directions can be fully utilized.

[0066] In one embodiment, after step S10, that is, after determining the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction, the method further includes:

[0067] When the first adjustment direction does not include any preset interference direction, the first limit position corresponding to the first adjustment direction is obtained; it can be understood that since the continuous movement of the vehicle seat along any preset interference direction may interfere with surrounding components, when the first adjustment direction does not include any preset interference direction (but only includes non-interference directions), it means that adjusting the vehicle seat according to the first seat adjustment instruction will not interfere with surrounding components; therefore, at this time, in order to simplify the calculation process and reduce the calculation load, there is no need to determine whether the vehicle seat reaches the preset interference position at the next adjustment moment based on the first Hall position information, but directly obtain the first limit position corresponding to the first adjustment direction, and then determine whether the vehicle seat reaches the first limit position at the next adjustment moment based on the first preset Hall position information.

[0068] When it is determined according to the first preset Hall position information that the vehicle seat has not reached the first limit position at the next adjustment moment, the first seat adjustment instruction is executed. It can be understood that at the next adjustment moment, when the vehicle seat reaches the corresponding limit coordinate position in at least one first adjustment direction (which can be determined by comparing the latest Hall number information corresponding to the first adjustment direction in the first preset Hall position information with the limit coordinate position), it means that the vehicle seat will reach the first limit position at the next adjustment moment; and when the vehicle seat does not reach the corresponding limit coordinate position in all first adjustment directions, it means that the vehicle seat has not reached the first limit position at the next adjustment moment, and the above-mentioned first seat adjustment instruction can be directly executed at this time, that is, the vehicle seat is controlled to move along the first adjustment direction until a stop instruction is received, or it is detected that the vehicle seat reaches the preset interference position or the first limit position at the next adjustment moment, and the first seat adjustment instruction can be stopped.

[0069] In one embodiment, after step S20, that is, after determining whether the vehicle seat reaches the preset interference position at the next adjustment moment according to the first Hall position information, it also includes: when it is determined that the vehicle seat will reach the preset interference position at the next adjustment moment, prompting interference information. That is, in this embodiment, if it is determined that the vehicle seat will reach the preset interference position at the next adjustment moment according to the first Hall position information, it means that the vehicle will immediately interfere with the surrounding components at the current moment, so it is not appropriate to move at this time (because the preset interference position is at a critical point, in order to maintain a sufficient gap with the surrounding components, the vehicle seat is preferably not to reach the preset interference position), but directly prompts the interference information through a preset prompting device (such as a display interface on the vehicle that displays the interference information, a voice device that voice prompts the interference information, etc.).

[0070] In one embodiment, after the step S30, after the first limit position corresponding to the first adjustment direction is obtained, the step further includes: when it is determined according to the first preset Hall position information that the vehicle seat will reach the first limit position at the next adjustment moment, prompting the limit position information. Understandably, at the next adjustment moment, when the vehicle seat reaches the limit coordinate position corresponding to it in at least one first adjustment direction (the determination can be made by comparing the latest Hall number information corresponding to the first adjustment direction in the first preset Hall position information with the limit coordinate position), it means that the vehicle seat will reach the first limit position at the next adjustment moment; at this time, it means that the vehicle is about to reach the limit coordinate position in at least one first adjustment direction at the current moment, and the vehicle seat should not move at this time (after the vehicle seat runs to the limit coordinate position in at least one first adjustment direction, even if the drive motor corresponding to the first adjustment direction continues to run, the vehicle seat will not continue to move, and may cause the drive motor to be blocked), but directly prompts the limit position information through a preset prompting device (such as a display interface on the vehicle displays the limit position information, a voice device voice prompts the limit position information, etc.).

[0071] In one embodiment, after step S40, that is, after executing the first seat adjustment instruction, the following steps are included:

[0072] S50, receiving a second seat adjustment instruction including a second adjustment direction, and determining the second Hall position information of the vehicle seat at the next adjustment moment according to the first Hall position information and the second adjustment direction; wherein the second seat adjustment instruction can be sent to the control module when the user triggers the adjustment switch on the vehicle seat, or can be input and sent to the control module through the vehicle display interface or voice instruction information. The second adjustment direction in the second seat adjustment instruction is one or more of the above-mentioned adjustable directions. It is understandable that the above-mentioned second adjustment direction may include a preset interference direction and / or a non-interference direction.

[0073] Among them, in the above step S40, after the first seat adjustment instruction is executed at the current time t0, the vehicle seat should be directly adjusted to the position corresponding to the first Hall position information at the next adjustment time t1. After time t1, if a second seat adjustment instruction is received, the time when the second seat adjustment instruction is received is the new current time, and the above first Hall position information is the new initial Hall position information corresponding to the current time; therefore, the above steps S10 to S40 can be referred to, and the second seat adjustment instruction can be processed according to steps S50-S80 in this embodiment.

[0074] Specifically, the Hall adjustment speed corresponding to each of the second adjustment directions and the time difference between the next adjustment moment and the new current moment are obtained; the Hall number information corresponding to each of the second adjustment directions in the first Hall position information is updated according to the time difference and the obtained Hall adjustment speeds, and the updated first Hall position information is recorded as the second Hall position information of the vehicle seat at the next adjustment moment.

[0075] S60, when the second adjustment direction includes at least one of the preset interference directions, determine whether the vehicle seat reaches the preset interference position at the next adjustment moment according to the second Hall position information; understandably, since the continuous movement of the vehicle seat along any preset interference direction may interfere with surrounding components, when the second adjustment direction includes at least one of the preset interference directions, it means that the vehicle seat is adjusted according to the second seat adjustment instruction, which may interfere with surrounding components; therefore, when the vehicle seat reaches the preset interference position at the next adjustment moment, it means that the vehicle will immediately interfere with surrounding components at the new current moment, so it is not appropriate to move at this time (since the preset interference position is at a critical point, in order to maintain a sufficient gap with surrounding components, the vehicle seat is preferably not to reach the preset interference position). When the vehicle seat does not reach the preset interference position at the next adjustment moment, it means that the vehicle will not interfere with surrounding components even if it continues to move, so the second seat adjustment instruction can be executed to adjust the vehicle seat after further determining in a subsequent step that the vehicle seat does not reach the second limit position at the next adjustment moment.

[0076] S70, when the preset interference position is not reached, the second extreme position corresponding to the second adjustment direction is obtained; understandably, in this embodiment, when it is determined that the preset interference position is not reached, it means that the vehicle seat will not interfere with the surrounding components at the next adjustment moment, but it cannot be determined whether the vehicle seat has reached the extreme coordinate positions corresponding to the second adjustment directions. Therefore, it is necessary to first obtain the second extreme position corresponding to the second adjustment direction, and then enter step S80 for further processing.

[0077] S80, when it is determined according to the second preset Hall position information that the vehicle seat has not reached the second limit position at the next adjustment moment, the second seat adjustment instruction is executed. It can be understood that at the next adjustment moment, when the vehicle seat reaches the corresponding limit coordinate position in at least one second adjustment direction (the limit coordinate position can be determined by comparing the limit coordinate position with the latest Hall number information corresponding to the second adjustment direction in the second preset Hall position information), it means that the vehicle seat will reach the second limit position at the next adjustment moment; and when the vehicle seat does not reach the corresponding limit coordinate position in all second adjustment directions, it means that the vehicle seat has not reached the second limit position at the next adjustment moment, and the above-mentioned second seat adjustment instruction can be directly executed at this time, that is, the vehicle seat is controlled to move along the second adjustment direction until a stop instruction is received, or it is detected that the vehicle seat reaches the preset interference position or a certain limit coordinate position at the next adjustment moment, and the second seat adjustment instruction can be stopped.

[0078] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0079] In one embodiment, a vehicle seat adjustment device is provided, which corresponds one-to-one to the vehicle seat adjustment method in the above embodiment. Figure 2 As shown, the vehicle seat adjustment device comprises:

[0080] A receiving module 11, configured to receive a first seat adjustment instruction including a first adjustment direction, and determine first Hall position information of the vehicle seat at a next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction;

[0081] a determination module 12, configured to determine, when the first adjustment direction includes at least one of the preset interference directions, whether the vehicle seat reaches a preset interference position at a next adjustment moment according to the first Hall position information;

[0082] An acquisition module 13, configured to acquire a first limit position corresponding to the first adjustment direction when the preset interference position is not reached;

[0083] The execution module 14 is used to execute the first seat adjustment instruction when it is determined according to the first preset Hall position information that the vehicle seat has not reached the first limit position at the next adjustment moment.

[0084] The vehicle seat adjustment device in the embodiment of the present invention, after determining the first Hall position information of the vehicle seat at the next adjustment moment according to the initial Hall position information of the vehicle seat and the first adjustment direction, if it is determined that the first adjustment direction includes at least one of the preset interference directions, at this time, continuing to move in the first adjustment direction may reach the preset interference position and interfere with surrounding components. Therefore, after the present invention determines that the vehicle seat has not reached the preset interference position at the next adjustment moment according to the first Hall position information, it will further judge whether it will reach the first extreme position corresponding to the first adjustment direction at the next adjustment moment. In this way, the subsequent seat adjustment process is always based on the premise that there will be no interference with surrounding components, thereby avoiding interference between the vehicle seat and surrounding components during the adjustment process and improving the user experience. Furthermore, the present invention executes the first seat adjustment instruction to specifically adjust the seat in the first adjustment direction (the first adjustment direction may be at least one direction) only after it determines that the vehicle seat will not reach the first limit position at the next adjustment moment, thereby avoiding the motor continuing to run and causing stalling after the vehicle seat reaches the limit position. In this way, the service life is improved while the user experience is further improved. In the present invention, when it is determined that the preset interference position and the first limit position have not been reached at the next adjustment moment, the seat can be arbitrarily adjusted in different first adjustment directions, thereby making more effective use of the interior space of the vehicle.
