TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of intelligent control of vehicle interiors, and in particular to an electric table board control method and device and a vehicle. BACKGROUND

[0002] In the design of automotive interiors, electric table boards are widely used as a means to improve passenger comfort and convenience. However, traditional vehicle electric table board control technology is limited by control mechanisms and technical design, lacking the ability to individually adjust and adaptively adjust the use angle of the electric table board, greatly affecting the passenger's use experience and comfort.

[0003] Currently, existing electric table boards are mainly fixed in a specific position and lack angle adjustment functionality, which limits the applicability of the table board as passengers cannot adjust the table board angle according to personal preferences or different use scenarios. In addition, the electric table board control technology in the prior art cannot adaptively adjust the use angle of the table board to respond to changes in other factors of the vehicle that affect the use angle of the table board.

[0004] Therefore, how to achieve individualized adjustment and adaptive control of the use angle of the electric table board is one of the important technical problems in the related technical field, and no effective solution has been proposed to address the above problems. SUMMARY

[0005] Embodiments of the present application provide an electric table board control method, device and vehicle, aiming to solve the technical problem of how to achieve individualized adjustment and adaptive control of the use angle of the electric table board.

[0006] According to an aspect of embodiments of the present application, an electric table board control method is provided, which is applied to a vehicle, the vehicle is provided with a seat, an electric table board is arranged on the back of the seat, and the electric table board control method comprises: in response to an opening request signal of the electric table board, obtaining a factory preset angle of the electric table board, a historical adjustment change amount of the electric table board, first vehicle posture information of the vehicle, and first seat posture information of the seat; determining a first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information; and driving the electric table board to move to the first target adjustment angle.

[0007] The above electric table board control method provided by the embodiments of the present application achieves the following technical effects: in response to the demand of the passenger to open the electric table board, the factory preset angle of the electric table board, the historical adjustment change amount of the electric table board, the first vehicle posture information of the vehicle, and the first seat posture information of the seat are obtained. The factory preset angle is the basic adjustment angle of the electric table board, which ensures the basic use state of the electric table board without external influence and provides a reference for subsequent angle adjustment; the historical adjustment change amount of the electric table board reflects the historical preference of the passenger for the adjustment of the electric table board, and by obtaining the historical adjustment change amount of the electric table board, the angle of the table board can be adjusted based on the historical preference of the passenger, thereby improving the individualization degree of the use of the table board; the first vehicle posture information reflects the posture deviation of the current vehicle, and by obtaining the first vehicle posture information, the deviation of the angle of the table board caused by the change of the posture of the vehicle is compensated, thereby ensuring that the table board remains in a stable state under different road conditions; the first seat posture information reflects the inclination degree of the backrest of the seat where the electric table board is located, and by obtaining the first seat posture information, the angle of the table board can be adjusted according to the real-time change of the posture of the seat, thereby keeping the table board at the angle expected by the passenger. According to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information, the first target adjustment angle is determined, so that the determined first target adjustment angle not only considers the individualized demand of the passenger, but also adapts to the current vehicle posture and seat posture. Finally, the electric table board is driven to move to the first target adjustment angle, thereby ensuring that the electric table board can accurately and quickly realize angle adjustment, and effectively guaranteeing that the demand of the passenger to open the electric table board is immediately met. Therefore, the embodiments of the present application can achieve the technical effect of individualized adjustment and adaptive control of the use angle of the electric table board, and solve the technical problem of how to realize individualized adjustment and adaptive control of the use angle of the electric table board.

[0008] Optionally, the electric table board control method further comprises: in response to the electric table board moving to the first target adjustment angle, acquiring second vehicle posture information of the vehicle and second seat posture information of the seat; comparing the first vehicle posture information and the second vehicle posture information to obtain a first comparison result; comparing the first seat posture information and the second seat posture information to obtain a second comparison result; in response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information are inconsistent, and the second comparison result indicating that the first seat posture information and the second seat posture information are inconsistent, determining a second target adjustment angle according to the factory preset angle, a historical adjustment change amount of the electric table board, the second vehicle posture information and the second seat posture information, and driving the electric table board to move to the second target adjustment angle; or in response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information are inconsistent, and the second comparison result indicating that the first seat posture information and the second seat posture information remain consistent, determining a third target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the second vehicle posture information and the first seat posture information, and driving the electric table board to move to the third target adjustment angle; or in response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information remain consistent, and the second comparison result indicating that the first seat posture information and the second seat posture information are inconsistent, determining a fourth target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information and the second seat posture information, and driving the electric table board to move to the fourth target adjustment angle.

[0009] The above optional embodiments of the present application can achieve the following technical effects: in response to the electric table plate moving to the first target adjustment angle, the second vehicle attitude information and the second seat attitude information of the vehicle are obtained, that is, the changes of the vehicle attitude and the seat attitude are further monitored, and the latest attitude information is collected to capture the changes of the vehicle attitude and the seat attitude. This mechanism ensures that after the table plate is adjusted in place, the dynamic changes of the vehicle attitude and the seat attitude are still continuously concerned, and instant feedback is provided for adaptive control. By comparing the first vehicle attitude information and the second vehicle attitude information and comparing the first seat attitude information and the second seat attitude information, it can be identified whether the vehicle attitude and the seat attitude have changed, which is a key condition for triggering further angle adjustment, ensuring the accuracy and timeliness of the table plate control. In response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information are inconsistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information are inconsistent, that is, the vehicle attitude and the seat attitude have changed, which will affect the current use angle of the table plate. Therefore, the latest second vehicle attitude information and second seat attitude information are used to calculate the target angle again, and the second target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table plate, the second vehicle attitude information and the second seat attitude information, for dynamic adjustment of the use angle of the table plate, ensuring that the use angle of the table plate can be quickly and adaptively adjusted regardless of the changes of the vehicle attitude and the seat attitude. Finally, the electric table plate is driven to move to the second target adjustment angle, ensuring the adaptive adjustment of the use angle of the table plate, realizing the continuous optimization of the use angle of the table plate, and overcoming the influence of the changes of the vehicle attitude and the seat attitude on the use angle of the table plate. Or in response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information are inconsistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information remain consistent, that is, the vehicle attitude has changed, and the seat attitude has not changed. Therefore, the latest vehicle attitude information is used to calculate the target angle, and the third target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table plate, the second vehicle attitude information and the first seat attitude information, and the electric table plate is driven to move to the third target adjustment angle, to overcome the influence of the change of the vehicle attitude on the use angle of the table plate. Similarly, in response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information remain consistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information are inconsistent, that is, the vehicle attitude remains unchanged, and the seat attitude changes. Therefore, the latest seat attitude information is used to calculate the target angle, and the fourth target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table plate, the first vehicle attitude information and the second seat attitude information, and the electric table plate is driven to move to the fourth target adjustment angle, to overcome the influence of the change of the seat attitude on the use angle of the table plate.

[0010] Optionally, the electric table board control method further comprises: in response to the adjustment signal of the electric table board, determining a current adjustment change amount of the electric table board according to the adjustment signal; determining a target adjustment change amount of the electric table board according to the current adjustment change amount and a historical adjustment change amount; determining a fifth target adjustment angle according to the factory preset angle, the target adjustment change amount of the electric table board, the first vehicle posture information and the first seat posture information; and driving the electric table board to move to the fifth target adjustment angle.

[0011] The above optional embodiments of the present application can achieve the following technical effects: according to the adjustment signal, the current adjustment change amount of the electric table board is determined, the adjustment intention of the passenger is accurately analyzed, the angle change that the passenger wants to adjust is quantified, a direct parameter is provided for accurate control of the table board angle, and it is ensured that the personalized needs of the passenger can be accurately captured and executed. According to the current adjustment change amount and the historical adjustment change amount, the target adjustment change amount of the electric table board, i.e. the new adjustment change amount that the passenger wants to achieve, is determined, so that the adjustment change amount is updated to meet the new adjustment needs of the passenger. According to the factory preset angle, the target adjustment change amount of the electric table board, the first vehicle posture information and the first seat posture information, the fifth target adjustment angle is determined, and the electric table board is driven to move to the fifth target adjustment angle, so that highly personalized adjustment of the use angle of the electric table board is realized, and the individuality and comfort of the passenger's use experience are ensured.

[0012] Optionally, driving the electric table board to move to the first target adjustment angle comprises: obtaining a current angle of the electric table board; comparing the current angle with the first target adjustment angle to obtain a comparison result; and in response to the comparison result indicating that the current angle is inconsistent with the first target adjustment angle, driving an execution motor of the electric table board to adjust the electric table board to move to the first target adjustment angle.

[0013] The above optional embodiments of the present application can achieve the following technical effects: by obtaining the current angle of the electric table board and comparing the current angle with the first target adjustment angle, it can be quickly identified whether the table board angle has reached the calculated first target adjustment angle. This instant comparison mechanism helps to improve the efficiency and accuracy of table board control, and ensures that each adjustment is based on the real difference between the current actual angle and the target angle. When it is determined that the current angle is different from the first target adjustment angle, the execution motor is driven for angle adjustment. This driving method not only saves energy, but also improves the pertinence of table board control.

[0014] Optionally, the first target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information, including: determining the first adjustment angle according to the first vehicle posture information; determining the second adjustment angle according to the first seat posture information; and determining the first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first adjustment angle, and the second adjustment angle.

[0015] The above optional embodiments of the present application can achieve the following technical effects: According to the real-time posture information of the vehicle, the angle compensation value that the table board needs to adjust due to the change of the vehicle posture, i.e., the first adjustment angle, is calculated. In this way, even if the vehicle is in a non-horizontal state, the table board can be adjusted to the desired use state of the passenger through the adjustment of the first adjustment angle. According to the first seat posture information, the second adjustment angle is calculated. This mechanism ensures that the table board angle can flexibly adapt to various changes in the seat posture. No matter how the seat back is adjusted, the table board can be adjusted to the desired use state of the passenger through the adjustment of the second adjustment angle. The first target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table board, the first adjustment angle, and the second adjustment angle. This multi-factor comprehensive calculation method ensures the individualization of the table board angle adjustment and the adaptability of the table board angle adjustment to the changes in the vehicle posture and the seat posture.

[0016] Optionally, the first adjustment angle is determined according to the first vehicle posture information, including: determining a vehicle inclination angle according to the first vehicle posture information, wherein the vehicle inclination angle is an inclination angle of the vehicle transversely relative to the horizontal plane; and determining the first adjustment angle according to the vehicle inclination angle.

[0017] The above optional embodiments of the present application can achieve the following technical effects: The determination of the vehicle inclination angle can accurately reflect the current non-horizontal state of the vehicle, which is the basis for the adaptive control of the table board angle. The first adjustment angle is determined according to the vehicle inclination angle to compensate for the angle deviation caused by the vehicle inclination. The determination of the first adjustment angle enables the table board to actively resist the influence of the change in the vehicle posture, ensuring that the table board can still maintain an ideal use angle in the vehicle inclination state. This greatly improves the experience of the passenger using the table board in a non-ideal road condition and increases the practicality of the table board function and the satisfaction of the passenger.

[0018] Optionally, the second adjustment angle is determined according to the first seat posture information, including: determining an inclination angle of a seat back according to the first seat posture information; and determining the second adjustment angle according to the inclination angle of the seat back and a preset conversion table, wherein the preset conversion table is used to reflect the influence degree of the inclination angle of the seat back on the angle of the electric table board.

[0019] The above optional embodiments of the present application can achieve the following technical effects: The determination of the inclination angle of the chair back is the basis for the adaptive adjustment of the table board angle. After the inclination angle of the chair back is determined, the inclination angle of the chair back is converted into a specific adjustment value of the table board angle, i.e., the second adjustment angle, through a preset conversion table. Through the preset conversion table, the adjustment angle corresponding to different inclination angles of the chair back can be determined to adaptively adjust the use angle of the electric table board in different seat postures.

[0020] Optionally, the electric table board control method further comprises: in response to a closing request signal of the electric table board, determining a target closing position angle; driving the electric table board to move to the target closing position angle; in response to the electric table board moving to the target closing position angle, storing a target adjustment change amount, and powering off the execution motor of the electric table board.

[0021] The above optional embodiments of the present application can achieve the following technical effects: The determination of the target closing position angle takes into account the storage space limitation and use safety of the table board, so that the closing operation of the table board is not only orderly, but also can reduce the collision risk caused by uncertain position, and protect the table board and other in-vehicle components from damage. After the target closing position angle is determined, the execution motor is purposefully controlled to guide the table board to move smoothly and accurately to the closing position. The intelligentization and automation of this process improve the efficiency and accuracy of the table board closing, and avoid the problems of inaccurate positioning or excessive force caused by manual closing. In addition, after the table board reaches the closing position, the target adjustment change amount is stored. The storage of this information is crucial for future individualized adjustment of the table board angle, so that the future table board angle adjustment can quickly return to the use angle preferred by the passenger. At the same time, the power-off operation of the execution motor ensures the conservation of power and prevents unnecessary energy consumption.

[0022] According to another aspect of the embodiments of the present application, an electric table board control device is also provided. The electric table board control device is applied to a vehicle, the vehicle is provided with a seat, and the chair back of the seat is provided with an electric table board. The electric table board control device comprises: an acquisition module, configured to acquire a factory preset angle of the electric table board, a historical adjustment change amount of the electric table board, first vehicle posture information of the vehicle, and first seat posture information of the seat in response to an opening request signal of the electric table board; a determination module, configured to determine a first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information; and a driving module, configured to drive the electric table board to move to the first target adjustment angle.

[0023] The above electric table board control device provided by the embodiment of the present application achieves the following technical effects: in response to the demand of the passenger to open the electric table board, the obtaining module obtains the factory preset angle of the electric table board, the historical adjustment change amount of the electric table board, the first vehicle posture information of the vehicle, and the first seat posture information of the seat. The factory preset angle is the basic adjustment angle of the electric table board, which ensures the basic use state of the electric table board without external influence and provides a reference for subsequent angle adjustment; the historical adjustment change amount of the electric table board reflects the historical preference of the passenger for the adjustment of the electric table board, and by obtaining the historical adjustment change amount of the electric table board, the angle of the table board can be adjusted based on the historical preference of the passenger, and the individuality of the use of the table board is improved; the first vehicle posture information reflects the posture deviation of the current vehicle, and by obtaining the first vehicle posture information, the deviation of the angle of the table board caused by the change of the posture of the vehicle is compensated, and the table board is ensured to remain in a stable state under different road conditions; the first seat posture information reflects the inclination degree of the backrest of the seat where the electric table board is located, and by obtaining the first seat posture information, the angle of the table board can be adjusted according to the real-time change of the posture of the seat, and the table board is kept at the angle expected by the passenger. The determining module determines the first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information, so that the determined first target adjustment angle takes into account the individualized demand of the passenger and adapts to the current vehicle posture and seat posture. Finally, the driving module drives the electric table board to move to the first target adjustment angle, so as to ensure that the electric table board can accurately and quickly realize angle adjustment, and effectively ensure that the demand of the passenger to open the electric table board is met immediately. Therefore, the embodiment of the present application can achieve the technical effect of individualized adjustment and adaptive control of the use angle of the electric table board, and solve the technical problem of how to realize the individualized adjustment and adaptive control of the use angle of the electric table board.

[0035] In order to make the technical problems, technical solutions and beneficial effects of the present application clearer, the present application will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0036] It should be noted that the terms "first", "second", and the like in the description and in the claims of the present application and the above-described accompanying drawings are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to such a process, method, product, or device.

[0037] The embodiments of the present application provide an electric table board control method, which is applied to a vehicle. The vehicle is provided with a seat. An electric table board is arranged on the back of the seat. Please refer to Figure 1 The electric table board control method comprises the following steps:

[0038] S10, in response to an opening request signal of the electric table board, obtaining a factory preset angle of the electric table board, a historical adjustment change amount of the electric table board, first vehicle posture information of the vehicle, and first seat posture information of the seat;

[0039] Optionally, the user generates the opening request signal of the electric table board in multiple input modes. For example, the opening request signal of the electric table board is generated by a physical button near the electric table board, a touch command of a vehicle central control screen, and a voice instruction. When the opening request signal of the electric table board is received, the electric table board angle adjustment control process is started.

[0040] The factory preset angle of the electric table board refers to an initial angle set for the electric table board in the vehicle manufacturing stage. The factory preset angle is determined based on ergonomics and the use habits of most users.

[0041] In an optional embodiment, the system records the historical data of the personalized adjustment of the electric table board angle, that is, the historical adjustment change amount of the electric table board. When the opening request signal of the electric table board is received, the historical adjustment change amount of the electric table board is called to consider the personal preference angle of the user when determining the target adjustment angle of the electric table board subsequently.

[0042] For example, in response to the opening request signal of the electric table board, the electric table board is driven to move to the factory preset angle, and then the user adjusts the angle of the electric table board to be 5° more upward than the factory preset angle. The difference of 5° is recorded as the historical adjustment change amount of the electric table board.

[0043] In addition, the vehicle will form a certain posture relative to the horizontal plane when it encounters a slope during travel. Vehicle posture information is collected by sensors (such as a full-vehicle gyroscope) built into the vehicle to reflect the degree of inclination of the vehicle. Vehicle posture information is crucial for adaptive adjustment of the table board, as it directly affects the response of the table board to slope changes. For example, if the vehicle is in an uphill state, the vehicle posture information will indicate that the table board needs to be tilted upward to maintain a horizontal or near-horizontal state.

[0044] Further, seat posture information is collected by the seat controller, and seat posture information is also important for adaptive adjustment of the electric table board. When the degree of inclination of the seat back changes, the overall posture of the electric table board provided on the seat back will also change accordingly, and therefore adaptive adjustment of the electric table board based on seat posture information is required.

[0045] S20, determining a first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information;

[0046] In an optional embodiment, the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information obtained are comprehensively considered to calculate the angle to which the electric table board should be adjusted, i.e., the first target adjustment angle.

[0047] S30, driving the electric table board to move to the first target adjustment angle.

[0048] When the first target adjustment angle is determined, the seat controller will send an instruction to the electric table board to execute the motor to drive the electric table board to move toward the target angle.

[0049] Optionally, the adjustment of the electric table board in the present application is achieved by adjusting the front end of the electric table board (i.e., the end close to the seat back).

[0050] The process of driving the electric table board to move to the first target adjustment angle involves closed-loop control, i.e., the angle sensor on the electric table board continuously monitors the actual angle of the electric table board and feeds back information to the seat controller to ensure that the electric table board can accurately and accurately stop at the target position.

[0051] The above electric table board control method provided by the embodiments of the present application achieves the following technical effects: in response to the demand of the passenger to open the electric table board, the factory preset angle of the electric table board, the historical adjustment change amount of the electric table board, the first vehicle posture information of the vehicle, and the first seat posture information of the seat are obtained. The factory preset angle is the basic adjustment angle of the electric table board, which ensures the basic use state of the electric table board without external influence and provides a reference for subsequent angle adjustment; the historical adjustment change amount of the electric table board reflects the historical preference of the passenger for the adjustment of the electric table board, and by obtaining the historical adjustment change amount of the electric table board, the angle of the table board can be adjusted based on the historical preference of the passenger, thereby improving the individualization degree of the use of the table board; the first vehicle posture information reflects the posture deviation of the current vehicle, and by obtaining the first vehicle posture information, the angle deviation of the table board caused by the change of the vehicle posture can be compensated, thereby ensuring that the table board remains stable under different road conditions; the first seat posture information reflects the inclination degree of the backrest of the seat where the electric table board is located, and by obtaining the first seat posture information, it is ensured that the angle of the table board can be adjusted according to the real-time change of the seat posture, thereby keeping the table board at the angle expected by the passenger. According to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information, the first target adjustment angle is determined, so that the determined first target adjustment angle takes into account the individualized demand of the passenger and adapts to the current vehicle posture and seat posture. Finally, the electric table board is driven to move to the first target adjustment angle, thereby ensuring that the electric table board can accurately and quickly achieve angle adjustment, and effectively ensuring that the demand of the passenger to open the electric table board is met immediately. Therefore, the embodiments of the present application can achieve the technical effect of individualized adjustment and adaptive control of the use angle of the electric table board, and solve the technical problem of how to achieve individualized adjustment and adaptive control of the use angle of the electric table board.

[0052] Optionally, the electric table board control method further comprises the following steps:

[0053] S401, in response to the electric table board moving to the first target adjustment angle, obtaining second vehicle posture information of the vehicle and second seat posture information of the seat;

[0054] After the electric table board is successfully adjusted to the first target adjustment angle, it does not mean that the adjustment control task is completed. Considering that the posture of the vehicle will change during the travel of the vehicle, and the posture of the seat will change when the passenger adjusts the position of the seat, the current posture of the vehicle and the current posture of the seat need to be reevaluated. The second vehicle posture information and the second seat posture information obtained are the results of reevaluating the current posture of the vehicle and the current posture of the seat.

[0055] It is appreciated that even after the motorized table board is adjusted to the first target position, the changes of the vehicle posture and the seat posture need to be continuously monitored to ensure that the motorized table board angle is real-time appropriate.

[0056] In an alternative embodiment, the vehicle built-in sensors (such as the vehicle-wide gyroscope) continuously detect the vehicle posture, especially when the vehicle goes through a slope or a curve, the vehicle inclination angle will change. For example, when the vehicle changes from uphill to flat road, or from straight driving to turning, the system will capture these changes in posture and use them as one of the bases for adjusting the use angle of the motorized table board.

[0057] In an alternative embodiment, the seat posture sensor continuously monitors the inclination of the seat back, especially when the passenger adjusts the seat to find a more comfortable posture. For example, when the front passenger of the vehicle changes from an upright sitting position to a semi-reclining state, this change will affect the overall posture of the motorized table board located on the seat back, thereby affecting the use experience of the rear passenger of the motorized table board. Therefore, the motorized table board angle needs to be adjusted accordingly to maintain a good use experience.

[0058] S402, compare the first vehicle posture information and the second vehicle posture information to obtain a first comparison result;

[0059] By comparing the first vehicle posture information and the second vehicle posture information, the change of the vehicle posture is analyzed, which is an important basis for determining whether the motorized table board needs to be self-adaptively adjusted. For example, if the first vehicle posture information shows that the vehicle is inclined by 5° on an uphill, and the second vehicle posture information shows that the vehicle is inclined by 3° on an uphill, then the first comparison result reveals that the vehicle posture has returned to the horizontal direction, prompting the front end of the motorized table board to be adjusted downward to compensate for this change and maintain the original use angle.

[0060] S403, compare the first seat posture information and the second seat posture information to obtain a second comparison result;

[0061] By comparing the first seat posture information and the second seat posture information, it is evaluated whether the posture of the seat where the motorized table board is located has changed. When the seat posture changes, the position of the motorized table board needs to be self-adaptively adjusted to adapt to the change of the seat posture. For example, if the seat back of the seat where the motorized table board is located is inclined by 10° backward from the upright state, then the front end of the motorized table board needs to be inclined by a certain angle forward to ensure the use experience of the passenger.

[0062] S404, in response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information are inconsistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information are inconsistent, determining a second target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the second vehicle attitude information and the second seat attitude information, and driving the electric table board to move to the second target adjustment angle;

[0063] When the comparison result indicates that both the vehicle attitude and the seat attitude have changed, the second target adjustment angle of the electric table board will be determined again to cope with these changes. This embodies the high intelligence and adaptability of the electric table board control method, ensuring that the electric table board can always provide the best user experience regardless of changes in external influencing factors. For example, if the vehicle changes from a 5° inclination to a 3° inclination, and the chair back reclines 10° from the upright state, the system will recalculate the inclination angle of the electric table board in combination with these changes to ensure that the electric table board still maintains the appropriate position and angle in the new attitude, meeting the user's needs.

[0064] S405, in response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information are inconsistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information remain consistent, determining a third target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the second vehicle attitude information and the first seat attitude information, and driving the electric table board to move to the third target adjustment angle;

[0065] In an optional embodiment, when the first comparison result indicates that the first vehicle attitude information and the second vehicle attitude information are inconsistent, and the second comparison result indicates that the first seat attitude information and the second seat attitude information are consistent, at this time, a third target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table board, the second vehicle attitude information and the first seat attitude information. That is, when the comparison result indicates that only the vehicle attitude has changed, the target adjustment angle of the electric table board, i.e. the third target adjustment angle, is determined again based on the updated vehicle attitude information (i.e. the second vehicle attitude information), and the electric table board is driven to move to the third target adjustment angle.

[0066] S406, in response to the first comparison result indicating that the first vehicle attitude information and the second vehicle attitude information remain consistent, and the second comparison result indicating that the first seat attitude information and the second seat attitude information are inconsistent, determining a fourth target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle attitude information and the second seat attitude information, and driving the electric table board to move to the fourth target adjustment angle.

[0067] In another alternative embodiment, when the first comparison result indicates that the first vehicle posture information and the second vehicle posture information are consistent, and the second comparison result indicates that the first seat posture information and the second seat posture information are inconsistent, the fourth target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information and the second seat posture information. That is, when the comparison result indicates that only the seat posture has changed, the target adjustment angle of the electric table board, i.e., the fourth target adjustment angle, is determined again based on the updated seat posture information (i.e., the second seat posture information), and the electric table board is driven to move to the fourth target adjustment angle.

[0068] The above optional embodiments of the present application can achieve the following technical effects: in response to the electric table moving to the first target adjustment angle, the second vehicle posture information of the vehicle and the second seat posture information of the seat are obtained, that is, the changes in the vehicle posture and seat posture are further monitored, and the latest posture information is collected to capture the changes in the vehicle posture and seat posture. This mechanism ensures that after the table is adjusted into place, it can still continue to pay attention to the dynamic changes of the vehicle posture and seat posture, providing instant feedback for adaptive control. By comparing the first vehicle posture information and the second vehicle posture information and comparing the first seat posture information and the second seat posture information, it is possible to identify whether the vehicle posture and seat posture have changed. This is a key condition for triggering further angle adjustment, ensuring the accuracy and timeliness of the table control. In response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information are inconsistent, and the second comparison result indicating that the first seat posture information and the second seat posture information are inconsistent, that is, the vehicle posture and the seat posture have changed, which will affect the current use angle of the table top, the target angle is calculated again using the latest second vehicle posture information and the second seat posture information. The second target adjustment angle is determined based on the factory preset angle, the historical adjustment change of the electric table top, the second vehicle posture information, and the second seat posture information, and is used to dynamically adjust the table top use angle to ensure that the table top use angle can be quickly and adaptively adjusted regardless of how the vehicle posture and the seat posture change. Finally, the electric table top is driven to move to the second target adjustment angle, ensuring the adaptive adjustment of the table top use angle, achieving continuous optimization of the table top use angle, and overcoming the influence of changes in vehicle posture and seat posture on the table top use angle. Or in response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information are inconsistent, and the second comparison result indicating that the first seat posture information and the second seat posture information are consistent, that is, the vehicle posture has changed but the seat posture has not changed, therefore, the target angle is calculated using the latest vehicle posture information, and a third target adjustment angle is determined based on the factory preset angle, the historical adjustment change of the electric table plate, the second vehicle posture information, and the first seat posture information, and the electric table plate is driven to move to the third target adjustment angle to overcome the influence of the vehicle posture change on the table plate's use angle. Similarly, in response to the first comparison result indicating that the first vehicle posture information and the second vehicle posture information are consistent, and the second comparison result indicating that the first seat posture information and the second seat posture information are inconsistent, that is, the vehicle posture remains unchanged but the seat posture changes, therefore, the target angle is calculated using the latest seat posture information, and a fourth target adjustment angle is determined based on the factory preset angle, the historical adjustment change of the electric table plate, the first vehicle posture information, and the second seat posture information, and the electric table plate is driven to move to the fourth target adjustment angle to overcome the influence of the seat posture change on the table plate's use angle.

[0069] Optionally, the electric table board control method further comprises the following steps:

[0070] S405, in response to the adjustment signal of the electric table board, determining a current adjustment change amount of the electric table board according to the adjustment signal;

[0071] When the passenger initiates an instruction to adjust the angle of the electric table board through a touch screen, a physical button, a voice command or the like, the seat controller will immediately respond to receive the adjustment signal. Subsequently, the adjustment signal is analyzed to determine the specific angle change that the passenger wants the electric table board to make, i.e. the current adjustment change amount. For example, the passenger indicates through a slider on the central control screen to tilt the electric table board by 5° upward from the current position, and the system will identify this change amount and prepare to execute it.

[0072] It should be noted that the current adjustment change amount of the electric table board reflects the passenger's immediate use demand.

[0073] S406, determining a target adjustment change amount of the electric table board according to the current adjustment change amount and a historical adjustment change amount;

[0074] After receiving the adjustment signal, the target adjustment change amount is determined according to the current adjustment change amount determined based on the adjustment signal, in combination with the historical adjustment change amount of the electric table board (the historical adjustment change amount is stored in the system memory and reflects the passenger's past operation preference), to determine the final angle that the electric table board needs to adjust. For example, the historical record shows that the passenger uses the table board by tilting it 10° upward more than the factory default angle (historical adjustment change amount), and the current instruction requires an additional tilt of 5° upward (current adjustment change amount), so the target adjustment change amount will be 15°.

[0075] S407, determining a fifth target adjustment angle according to the factory default angle, the target adjustment change amount of the electric table board, first vehicle posture information and first seat posture information;

[0076] After determining the target adjustment change amount, the first vehicle posture information and the first seat posture information are combined with the current factory default angle of the vehicle to calculate the next target angle that the electric table board should adjust to, i.e. the fifth target adjustment angle.

[0077] S408, driving the electric table board to move to the fifth target adjustment angle.

[0078] The electric table board is driven to execute the motor to move until the electric table board moves to the fifth target adjustment angle.

[0079] The above optional embodiments of the present application can achieve the following technical effects: according to the adjustment signal, the current adjustment change amount of the electric table board is determined, the adjustment intention of the passenger is accurately analyzed, the angle change that the passenger wants to adjust is quantified, a direct parameter is provided for accurate control of the table board angle, and it is ensured that the personalized needs of the passenger can be accurately captured and executed. According to the current adjustment change amount and the historical adjustment change amount, the target adjustment change amount of the electric table board, i.e., the new adjustment change amount that the passenger wants to achieve, is determined, so that the adjustment change amount is updated to meet the new adjustment needs of the passenger. According to the factory preset angle, the target adjustment change amount of the electric table board, the first vehicle posture information and the first seat posture information, the fifth target adjustment angle is determined, and the electric table board is driven to move to the fifth target adjustment angle, so that the highly personalized adjustment of the use angle of the electric table board is realized, and the personalization and comfort of the passenger's use experience are ensured.

[0080] Optionally, in step S30, the electric table board is driven to move to the first target adjustment angle, including the following steps:

[0081] S301, obtaining the current angle of the electric table board;

[0082] At any stage of the angle adjustment of the electric table board, it is necessary to determine which angle the electric table board is currently in, which is the basis for subsequent comparison and adjustment. The seat controller obtains this information through the angle sensor connected to the actuator of the electric table board. The angle sensor can monitor the position of the electric table board in real time, and can accurately read the position of the electric table board whether the electric table board is in a closed state, a preset angle or an arbitrary angle. For example, if the electric table board is currently adjusted to a backward inclination of 20°, the sensor will immediately capture this information to prepare for subsequent comparison and adjustment.

[0083] S302, comparing the current angle with the first target adjustment angle to obtain a comparison result;

[0084] The obtained current angle is compared with the determined first target adjustment angle, and this comparison process will determine whether the system needs to drive the table board to adjust the motor. Based on the comparison result, it can be determined whether the current angle reaches or deviates from the target angle, which provides a basis for decision-making for the next action.

[0085] S303, in response to the comparison result indicating that the current angle is inconsistent with the first target adjustment angle, driving the actuator of the electric table board to adjust the electric table board to move to the first target adjustment angle.

[0086] When the comparison result shows that the current angle is inconsistent with the first target angle, i.e., there is a deviation, the system will immediately respond to start the table board execution motor to make necessary angle adjustment until the electric table board reaches the first target angle. This adjustment process is realized by forward or reverse rotation of the motor, depending on the relationship between the current angle of the electric table board and the first target angle. For example, if the electric table board is currently inclined backward by 25°, and the target angle is to be inclined backward by 30°, then the system will drive the motor to rotate forward until the electric table board angle reaches 30°; conversely, if the target angle is smaller than the current angle, the system will drive the motor to rotate in reverse to gradually reduce the electric table board angle.

[0087] The above optional embodiments of the present application can achieve the following technical effects: by obtaining the current angle of the electric table board and comparing the current angle with the first target adjustment angle, it can quickly identify whether the table board angle has reached the calculated first target adjustment angle. This immediate comparison mechanism helps to improve the efficiency and accuracy of table board control, ensuring that each adjustment is based on the real difference between the current actual angle and the target angle. When it is determined that there is a difference between the current angle and the first target adjustment angle, the execution motor is driven for angle adjustment. This driving method not only saves energy, but also improves the pertinence of table board control.

[0088] Optionally, in step S20, the first target adjustment angle is determined according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information and the first seat posture information, including the following steps:

[0089] S201, determining the first adjustment angle according to the first vehicle posture information;

[0090] The vehicle will encounter various road conditions during driving, such as uphill and downhill, turning, etc., which will cause changes in the vehicle posture. The first vehicle posture information is obtained by the vehicle's built-in sensors (such as a gyroscope or an accelerometer), which describes the degree of inclination of the vehicle relative to the horizontal plane. The seat controller receives the first vehicle posture information and calculates the angle that the electric table board needs to compensate according to the specific value of the vehicle posture, i.e., the first adjustment angle. This calculation takes into account the influence of vehicle posture changes on the stability of the table board, ensuring that passengers can normally use the table board even in complex road conditions.

[0091] For example, the first vehicle posture information shows that the vehicle is currently experiencing a 5° downhill, i.e., -5°. In this case, the front end of the electric table board is inclined downward by 5° relative to the horizontal plane, and therefore the first adjustment angle is determined to be +5°, i.e., the front end of the electric table board needs to be adjusted to incline upward by 5° to offset the natural downward inclination caused by the downhill.

[0092] It is not difficult to understand that the first adjustment angle is used to offset the influence of the whole vehicle posture change on the table board use angle, to ensure that the use experience of the electric table board is not affected by the road conditions.

[0093] S202, determine a second adjustment angle according to the first seat posture information;

[0094] The change of the seat posture will also affect the use experience of the table board. The first seat posture information refers to the inclination angle of the front seat back relative to the vertical direction, which is also collected by the sensor built-in the seat. The seat controller calculates the second adjustment angle of the electric table board according to the inclination angle of the front seat, to ensure that the electric table board maintains appropriate space and angle with the passenger, in line with the ergonomic principle, and improves the use comfort.

[0095] For example, if the first seat posture information shows that the seat back is inclined backward by 15°, the front end of the electric table board needs to be inclined forward by a certain angle, such as 5°, to adapt to the inclination of the seat back and avoid the table board being too close to the passenger, affecting the use space.

[0096] S203, determine a first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first adjustment angle and the second adjustment angle.

[0097] According to the factory preset angle, the historical adjustment change amount of the electric table board, and the first adjustment angle and the second adjustment angle determined above, the final first target adjustment angle is calculated. This angle will be the basis for the table board to execute motor adjustment, to ensure that the adjustment of the electric table board meets the personalized needs of the passenger and adapts to the current vehicle and seat posture changes, to provide the best use experience.

[0098] The above optional embodiments of the present application can achieve the following technical effects: according to the real-time posture information of the vehicle, the angle compensation value that the table board needs to adjust due to the change of the vehicle posture, i.e. the first adjustment angle, is calculated, so that even if the vehicle is in a non-horizontal state, the table board can be adjusted to the desired use state of the passenger through the adjustment of the first adjustment angle. According to the first seat posture information, the second adjustment angle is calculated, which ensures that the table board angle can flexibly adapt to various changes of the seat posture, and no matter how the seat back is adjusted, the table board can be adjusted to the desired use state of the passenger through the adjustment of the second adjustment angle. According to the factory preset angle, the historical adjustment change amount of the electric table board, the first adjustment angle and the second adjustment angle, the first target adjustment angle is determined, and this multi-factor comprehensive calculation method ensures the personalization of the table board angle adjustment and the adaptability of the table board angle adjustment to the changes of the vehicle posture and the seat posture.

[0099] Optionally, Figure 2is an example diagram of the electric table board angle setting provided by an embodiment of the present application, please refer to Figure 2 The seat controller determines the table board target angle G-Ang based on the basic opening angle B-Ang, the user adjustment amount A-Ang, the seat back adjustment angle S-Ang, and the vehicle posture offset V-Ang.

[0100] Optionally, the basic opening angle B-Ang (i.e. the factory preset angle) is set before the vehicle is shipped from the factory, which is an angle suitable for some users to use the table board. This parameter cannot be changed.

[0101] Optionally, the user adjustment amount A-Ang (i.e. the historical adjustment change amount of the electric table board) is the historical adjustment amount of the user to the table board use angle according to the personal use habit or the need of different use scenarios, which is adjusted through the table board angle adjustment button, the central control screen, the voice assistant, etc.

[0102] Optionally, the seat back adjustment angle S-Ang (i.e. the second adjustment angle) is calculated according to the use angle of the backrest of the electric table board installed seat, which is related to the front seat backrest angle and the seat structure. The use angle of the backrest of the electric table board installed seat is determined based on the seat posture information.

[0103] Optionally, the vehicle posture offset V-Ang (i.e. the first adjustment angle) is a parameter for compensation according to the change of the vehicle posture, which takes the inclination value of the vehicle posture transverse to the horizontal plane as the basis for the compensation amount, and balances the change of the table board horizontal amount caused by the vehicle on the slope.

[0104] Optionally, G = B + A - S + V, wherein B is the basic opening angle, A is the user adjustment amount, S is the seat back adjustment angle, V is the vehicle posture offset, and G is the table board target angle.

[0105] Optionally, Figure 3 is a flowchart of the electric table board opening control provided by an embodiment of the present application, please refer to Figure 3 The electric table board opening control includes the following steps:

[0106] When the user requests to open the table board through the key / central control screen / voice assistant, etc., the seat controller receives the request signal and starts to execute the table board opening action; the B-Ang set by the factory and the user adjustment amount A-Ang recorded before the last power-off are called from the storage; the vehicle attitude information is obtained from the vehicle gyroscope and sent to the seat controller through the central controller, and the seat controller processes the vehicle attitude information to calculate the vehicle attitude offset V-Ang; the seat backrest angle information is obtained to calculate the seat backrest adjustment angle S-Ang; the target angle G-Ang of the table board is calculated through the obtained basic opening angle B-Ang, user adjustment amount A-Ang, seat backrest adjustment angle S-Ang, and vehicle attitude offset V-Ang; the current angle of the table board panel is obtained, and it is judged whether the current angle of the table board is consistent with the target angle; if consistent, the seat backrest adjustment angle S-Ang and the vehicle attitude offset V-Ang are re-obtained, and then the target angle of the table board is calculated again; if the panel angle is inconsistent with the target angle, the seat controller drives the table board to execute the motor until the table board panel is driven to the target angle; when the table board reaches the target angle, the seat backrest adjustment angle S-Ang and the vehicle attitude offset V-Ang are always obtained and updated, and then the target angle G-Ang of the table board is calculated to adjust the panel angle of the table board to be consistent with the target angle, forming an adaptive function.

[0107] In the electric table board opening control process, when the table board is in an open state, the user adjusts the table board angle through the key / central control screen / voice assistant, etc., and the seat controller responds to the user adjustment. The seat controller updates the user adjustment amount A-Ang value and recalculates the target angle, repeating the above steps to achieve table board angle adjustment.

[0108] Optionally, in step S201, the first adjustment angle is determined according to the first vehicle attitude information, including the following steps:

[0109] S2011, determining a vehicle inclination angle according to the first vehicle attitude information, wherein the vehicle inclination angle is an inclination angle of a vehicle transverse relative to a horizontal plane;

[0110] The first vehicle attitude information is obtained by using the sensors built in the vehicle, such as a gyroscope or an accelerometer. By analyzing the first vehicle attitude information, the vehicle inclination angle is determined, that is, the inclination angle of the vehicle transverse relative to the horizontal plane is analyzed.

[0111] S2012, determining the first adjustment angle according to the vehicle inclination angle.

[0112] After the vehicle inclination angle is determined, the first adjustment angle of the electric table board is determined according to this value to ensure that the electric table board can still maintain a stable use state after compensating for the influence of vehicle inclination, and the objects on the table will not fall off due to vehicle inclination.

[0113] In an optional embodiment, the vehicle inclination angle is 5°, and the first adjustment angle is set to -5°, that is, the front end of the table board needs to be adjusted by 5° in the opposite direction of the inclination to offset the impact of the lateral inclination.

[0114] The above optional embodiments of the present application can achieve the following technical effects: The determination of the vehicle inclination angle can accurately reflect the current non-horizontal state of the vehicle, which is the basis for adaptive control of the table board angle. According to the vehicle inclination angle, the first adjustment angle is determined to compensate for the angle deviation caused by the vehicle inclination. The determination of the first adjustment angle enables the table board to actively resist the impact of the vehicle posture change, ensuring that the table board can still maintain an ideal use angle in the vehicle inclination state, which greatly improves the experience of passengers using the table board in non-ideal road conditions and increases the practicality of the table board function and the satisfaction of passengers.

[0115] Optionally, in step S202, the second adjustment angle is determined according to the first seat posture information, including the following steps:

[0116] S2021, determining the inclination angle of the seat back according to the first seat posture information;

[0117] The seat controller obtains the first seat posture information according to the sensors built-in the seat, such as position sensors or angle sensors. By analyzing the first seat posture information, the inclination angle of the current seat back relative to the vertical direction, that is, the inclination angle of the seat back, is obtained.

[0118] S2022, determining the second adjustment angle according to the inclination angle of the seat back and a preset conversion table, wherein the preset conversion table is used to reflect the influence degree of the inclination angle of the seat back on the angle of the electric table board.

[0119] After the inclination angle of the seat back is determined, the second adjustment angle is determined by referring to the preset conversion table.

[0120] In an optional embodiment, the preset conversion table is table data used to reflect the relationship between the inclination angle of the seat back and the angle requirement of the electric table board. It provides the ideal angle adjustment amount of the electric table board at different inclination angles of the seat back to maintain the appropriate distance and angle between the table board and the passenger.

[0121] For example, the inclination angle of the seat back is 10° backward, by querying the preset conversion table, it is determined that the front end of the electric table board should be inclined 5° forward to provide the best use experience, then the 5° forward inclination is taken as the second adjustment angle.

[0122] The above-described optional embodiment of the present application can achieve the following technical effects: Determining the chair back tilt angle serves as the basis for adaptively adjusting the tabletop angle. After determining the chair back tilt angle, the chair back tilt angle is converted into a specific adjustment value for the tabletop angle, i.e., the second adjustment angle, using a preset conversion table. The preset conversion table can determine the adjustment angle corresponding to different chair back tilt angles, thereby adaptively adjusting the operating angle of the electric tabletop in different seating postures.

[0123] Optionally, the electric table top control method further includes the following steps:

[0124] S501, in response to a closing request signal of the electric table top, determining a target closing position angle;

[0125] When a passenger issues a command to close the powered table tray via the central control screen, a physical button, or a voice command, the specific angle to which the powered table tray should close is determined. This angle is referred to as the target closing angle. In an optional embodiment, the target closing angle is preset by the vehicle manufacturer during table tray design to ensure that the table tray does not interfere with other vehicle interior functions or passenger space when closed.

[0126] S502, driving the electric table top to move to the target closed position angle;

[0127] After determining the target closed angle, the tabletop actuator motor is driven, and through the mechanical movement of the tabletop actuator, the tabletop panel is gradually moved from its current open state to the target closed angle. This process involves multiple fine-tuning steps to ensure that the tabletop accurately reaches the target position angle when closing, avoiding collisions or noise, while ensuring a smooth and safe closing process.

[0128] S503 , in response to the electric table top moving to the target closed position angle, storing the target adjustment change amount, and powering off the actuator motor of the electric table top.

[0129] When the electric table reaches its target closed position, the target adjustment change is recorded. This change reflects the passenger's individual needs and usage habits when using the electric table, serving as a reference for future automatic table adjustments. To conserve energy and prevent accidental movement, the actuator motor is powered off, ensuring the stability and safety of the table in the closed state.

[0130] The above optional embodiment of the present application can achieve the following technical effects: the determination of the target closing position angle takes into account the storage space limitation of the table board and the use safety, so that the closing operation of the table board is not only orderly, but also can reduce the collision risk caused by uncertain position, and protect the table board and other in-vehicle components from damage. After the target closing position angle is determined, the electric motor is controlled purposefully to guide the table board to move smoothly and accurately to the closing position. The intelligentization and automation of this process improve the efficiency and accuracy of the table board closing, and avoid the problems of inaccurate positioning or excessive force caused by manual closing. In addition, after the table board reaches the closing position, the target adjustment change amount is stored, and the storage of this information is crucial for future individualized adjustment of the table board angle, so that the future table board angle adjustment can quickly recover to the favorite use angle of the passenger. At the same time, the power-off operation of the electric motor ensures the conservation of power and prevents unnecessary energy consumption.

[0131] Optionally, Figure 4 is a flow chart of the electric table board closing control provided by an embodiment of the present application, please refer to Figure 4 , the electric table board closing control includes the following steps:

[0132] The user initiates a request to close the table board through a key, a central control screen or the like; the seat controller responds to the table board closing request signal; sets the table board target angle G-Ang to the closing position angle C-Ang; obtains whether the table board panel angle is consistent with the target angle G-Ang, if not, the seat controller drives the table board execution motor to drive the table board to move in the closing direction, and again judges whether the panel angle is consistent with the target angle, until the table board panel angle is consistent with the target angle; the table board motor is powered off, the user adjustment amount A-Ang before closing is stored, so as to calculate the target angle next time when opening, and at the same time, the seat backrest adjustment angle S-Ang and the vehicle attitude offset V-Ang are stopped.

[0133] Optionally, Figure 5 is a hardware architecture diagram of the electric table board system provided by an embodiment of the present application, please refer to Figure 5 , the electric table board system includes:

[0134] The vehicle central controller and the seat controller connected through a bus, and the two exchange information, and the bus scheme can be CAN bus or LIN bus. The vehicle central controller converts the control request of the table board opening, closing and angle adjustment from the central control screen or voice assistant and the like, and the vehicle attitude information obtained by the vehicle gyroscope into bus signals, and sends the control request to the seat controller through the bus. At the same time, the seat controller sends the current table board opening angle and the like to the vehicle central controller through the bus.

[0135] The buttons for controlling the table board switch and the table board angle adjustment are arranged near the electric table board or near the user seat, and are connected to the seat controller through a hard wire to control the table board opening, closing and angle adjustment. The table board switch button and the table board angle adjustment button are not necessarily present, and preferably, the table board switch button and the table board angle adjustment button are present.

[0136] The seat controller is connected to the table board execution motor through a hard wire, the output end of the table board execution motor is connected to the table board execution mechanism through a mechanical structure, and the table board execution mechanism is connected to the table board panel through a mechanical mechanism. The seat controller controls the forward rotation and reverse rotation of the table board execution motor to realize the control of the movement of the table board panel in the opening direction and the closing direction.

[0137] An angle sensor or a position sensor is arranged on the table board execution motor or the table board execution mechanism to obtain the position information of the table board in real time and calculate the opening angle of the table board.

[0138] The table board angle sensor is connected to the seat controller through a hard wire to transmit the obtained table board opening angle information to the seat controller.

[0139] According to another aspect of the embodiment of the present application, an electric table board control device 600 is also provided, which is applied to a vehicle, the vehicle is provided with a seat, and the seat back is provided with an electric table board. Please refer to Figure 6 The electric table board control device 600 comprises: an acquisition module 610, configured to acquire the factory preset angle of the electric table board, the historical adjustment change amount of the electric table board, the first vehicle posture information of the vehicle and the first seat posture information of the seat in response to the opening request signal of the electric table board; a determination module 620, configured to determine a first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information and the first seat posture information; and a driving module 630, configured to drive the electric table board to move to the first target adjustment angle.

[0140] The above electric table board control device 600 provided by the embodiments of the present application achieves the following technical effects: in response to the demand of the passenger to open the electric table board, the obtaining module 610 obtains the factory preset angle of the electric table board, the historical adjustment change amount of the electric table board, the first vehicle posture information of the vehicle, and the first seat posture information of the seat. The factory preset angle is the basic adjustment angle of the electric table board, which ensures the basic use state of the electric table board without external influence and provides a reference for subsequent angle adjustment; the historical adjustment change amount of the electric table board reflects the historical preference of the passenger for the adjustment of the electric table board, and by obtaining the historical adjustment change amount of the electric table board, the angle of the table board can be adjusted based on the historical preference of the passenger, and the individuality of the use of the table board is improved; the first vehicle posture information reflects the posture deviation of the current vehicle, and by obtaining the first vehicle posture information, the angle deviation of the table board caused by the change of the vehicle posture is compensated, and the table board is ensured to remain in a stable state under different road conditions; the first seat posture information reflects the inclination degree of the backrest of the seat where the electric table board is located, and by obtaining the first seat posture information, the angle of the table board can be adjusted according to the real-time change of the seat posture, and the table board is kept at the angle expected by the passenger. The determining module 620 determines the first target adjustment angle according to the factory preset angle, the historical adjustment change amount of the electric table board, the first vehicle posture information, and the first seat posture information, so that the determined first target adjustment angle takes into account the individualized demand of the passenger and adapts to the current vehicle posture and seat posture. Finally, the driving module 630 drives the electric table board to move to the first target adjustment angle, ensuring that the electric table board can accurately and quickly realize angle adjustment, and effectively ensuring that the demand of the passenger to open the electric table board is met immediately.
