Description

Technical Field

[0001] The present application relates to the field of vehicles, and more specifically, to a control method, device, vehicle and storage medium for an electrically adjustable column in the field of vehicles. Background Art

[0002] The electric control column is an important component in the automobile steering system. It is automatically adjusted by motor drive. However, with the development of wire-controlled steering technology, the electric control column often requires a larger telescopic range during axial adjustment. However, due to the limitations of the design position and the upper limit position, the telescopic range of the column is limited by surrounding components at different positions, resulting in insufficient adjustment space. Therefore, it is very necessary to solve the space limitations that may be encountered when the electric control column is adjusted over a large stroke.

[0003] In the related art, the telescopic range of the design position is usually shortened and limited to a specific telescopic range to avoid conflict between the electric adjustment column and surrounding components when it is in the extreme position. However, this also limits the design flexibility of the vehicle and reduces the user's operating experience, which urgently needs to be solved. Summary of the invention

[0004] The present application provides a control method, device, vehicle and storage medium for an electrically adjustable column. The method can adjust the angle and / or length of the electrically adjustable column according to the number and position of the Hall sensors corresponding to different angles or lengths, thereby ensuring that the adjustment range of the electrically adjustable column is maximized without interfering with surrounding components, while improving the design flexibility of the vehicle and the user's operating experience.

[0005] In a first aspect, a control method for an electrically adjustable column is provided, the method comprising: determining whether a steering wheel adjustment command from a user is received; if the steering wheel adjustment command is received, determining whether a position of the electrically adjustable column is within a preset adjustment range based on the steering wheel adjustment command; if the position of the electrically adjustable column is not within the preset adjustment range, adjusting the position of the electrically adjustable column, and when the position of the electrically adjustable column is adjusted to the boundary of the preset coordinated adjustment range, adjusting the position of the electrically adjustable column accordingly according to a pre-constructed mapping relationship of the electrically adjustable column angle-length adjustment.

[0006] Through the above technical solution, the angle and / or length of the electric control column can be adjusted according to the number and position of the Hall sensors, thereby ensuring that the adjustment range of the electric control column is maximized without interfering with surrounding components, while improving the design flexibility of the vehicle and the user's operating experience.

[0007] In combination with the first aspect, in some possible implementations, the electrically adjustable column position includes an electrically adjustable column angle position and an electrically adjustable column length position, and judging whether the electrically adjustable column position is within a preset adjustment range based on the steering wheel adjustment instruction includes: if the steering wheel adjustment instruction is a steering wheel length adjustment instruction, judging whether the electrically adjustable column angle position is within a preset angle range based on the steering wheel length adjustment instruction; or, if the steering wheel adjustment instruction is a steering wheel angle adjustment instruction, judging whether the electrically adjustable column length position is within a preset length range based on the steering wheel angle adjustment instruction.

[0008] Through the above technical solution, the position of the electric adjustment column angle is determined by the steering wheel length adjustment command, and / or the position of the electric adjustment column length is determined by the steering wheel angle adjustment command, so that adjustments are made based on different needs of users, thereby improving driving comfort.

[0009] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, the judging whether the position of the electrically adjustable column is within the preset adjustment range based on the steering wheel adjustment instruction also includes: if the angle position of the electrically adjustable column is not within the preset angle range, and / or the length position of the electrically adjustable column is not within the preset length range, then it is determined that the position of the electrically adjustable column is not within the preset adjustment range.

[0010] Through the above technical solution, the position of the electrically adjustable tube column is determined based on the length position of the electrically adjustable tube column and the length position of the electrically adjustable tube column, so that position adjustment can be implemented separately based on different adjustment instructions, thereby improving the adjustment accuracy.

[0015] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, after determining whether the slope of the electrically adjustable tube column angle-length is the preset target slope, it also includes: if the slope of the electrically adjustable tube column angle-length is not the preset target slope, determining the target adjustment object and the target value of the target adjustment object according to the slope of the electrically adjustable tube column angle-length, and adjusting the target adjustment object according to the target value, so that the angle and length of the electrically adjustable tube column are within the boundary of the preset coordinated adjustment range.

[0016] Through the above technical solution, by using adjustment strategies corresponding to different slopes, adjustments are made based on target adjustment objects corresponding to different slopes, thereby improving the adjustment accuracy of the electrically adjustable pipe string position.

[0017] In combination with the first aspect and the above-mentioned implementation methods, in some possible implementation methods, determining the target adjustment object according to the slope of the electrically adjustable tube column angle-length includes: when the slope of the electrically adjustable tube column angle-length is 0, the target adjustment object is the angle of the electrically adjustable tube column; when the slope of the electrically adjustable tube column angle-length is ∞, the target adjustment object is the length of the electrically adjustable tube column.

[0018] Through the above technical solution, different electric control string adjustment strategies are determined by two special slopes of the electric control string angle and length, thereby ensuring that the adjustment process is accurate and correct.

[0049] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0050] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0051] The electric control column is an important component in the automobile steering system. It is mainly used to adjust the position of the steering wheel (including height and front-to-back distance) to adapt to the body shape and driving habits of different users. The electric control column is automatically adjusted by motor drive, replacing the traditional manual adjustment method, thereby improving driving comfort and convenience. However, the electric control column often requires a larger telescopic range during axial adjustment. However, due to the limitations of the design position and the upper limit position, the telescopic range of the electric control column is limited by surrounding components at different positions, resulting in insufficient adjustment space. For example, at the design position, the maximum allowable retraction amount of the electric control column can be 80mm, but at the upper limit position, the maximum allowable retraction amount of the electric control column is 80mm. The allowable retraction amount is only 60mm. If the telescopic range exceeds 60mm, it will result in insufficient clearance with surrounding components. The existing solution is usually to shorten the telescopic range of the design position and limit it to 60mm to avoid conflict with surrounding components at the extreme position. However, this also limits the design flexibility of the vehicle and reduces the user's operating experience. Therefore, in order to solve the space limitation problem encountered by the electric adjustable column during large-stroke control, the embodiment of the present application uses a specific control strategy to optimize the length and angle adjustment of the electric adjustable column, thereby ensuring that the adjustment range of the electric adjustable column is maximized without interfering with surrounding components, while improving the design flexibility of the vehicle and the user's operating experience.

[0052] Figure 1 It is a schematic flow chart of a control method of an electrically adjustable pipe string provided in an embodiment of the present application.

[0053] For example, Figure 1 As shown, the method includes:

[0054] In step S101, it is determined whether a steering wheel adjustment instruction from a user is received.

[0055] Among them, the steering wheel adjustment instructions may include steering wheel length adjustment instructions and steering wheel angle adjustment instructions. For example, by selecting the length adjustment button IN or OUT, the length motor is driven to control the length adjustment of the electric adjustment column, or by selecting the angle adjustment button DOWN or UP, the angle motor is driven to control the angle adjustment of the electric adjustment column.

[0056] Specifically, Figure 2As shown, if the user wants to adjust the steering wheel during driving, first, the user can send a steering wheel adjustment command through the steering wheel button. For example, if the user wants to adjust the angle of the steering wheel, the steering wheel angle adjustment command is sent through the steering wheel button (DOWN or UP); if the user wants to adjust the length of the steering wheel, the steering wheel length adjustment command is sent through the steering wheel button (IN or OUT); after receiving the steering wheel angle adjustment command or length adjustment command sent by the user, the position of the electric adjustment column is further determined to perform subsequent adjustments according to the position of the electric adjustment column.

[0057] In step S102, if a steering wheel adjustment command is received, it is determined whether the position of the electric control column is within a preset adjustment range based on the steering wheel adjustment command.

[0058] Optionally, in one embodiment of the present application, the position of the electrically adjustable column includes the electrically adjustable column angle position and the electrically adjustable column length position, and whether the position of the electrically adjustable column is within a preset adjustment range is judged based on the steering wheel adjustment instruction, including: if the steering wheel adjustment instruction is a steering wheel length adjustment instruction, then judging whether the electrically adjustable column angle position is within the preset angle range based on the steering wheel length adjustment instruction; or, if the steering wheel adjustment instruction is a steering wheel angle adjustment instruction, then judging whether the electrically adjustable column length position is within the preset length range based on the steering wheel angle adjustment instruction.

[0059] Among them, the preset adjustment range refers to the safe adjustment range of the electric adjustment string, which may include a preset angle range and a preset length range, wherein the preset angle range and the preset length range may be set by technical personnel in this field according to actual design requirements, or may be obtained through a limited number of computer simulations, and are not specifically limited here.

[0060] Specifically, in an embodiment of the present application, the position of the electrically adjustable column may include an electrically adjustable column angle position and an electrically adjustable column length position. If the steering wheel adjustment instruction is a steering wheel length adjustment instruction, then based on the steering wheel length adjustment instruction, the Hall sensor corresponding to the angle adjustment detects the angle position of the electrically adjustable column, and determines whether the angle position of the electrically adjustable column is within a preset angle range, that is, whether the angle position of the electrically adjustable column is within a safe adjustment range of the angle adjustment. Alternatively, if the steering wheel adjustment instruction is a steering wheel angle adjustment instruction, then based on the steering wheel angle adjustment instruction, the Hall sensor corresponding to the length adjustment detects the length position of the electrically adjustable column, and determines whether the length position of the electrically adjustable column is within a preset length range, that is, whether the length position of the electrically adjustable column is within a safe adjustment range of the length adjustment.

[0061] Preferably, if Figure 3As shown, since the angle adjustment of the electric adjustable column has a larger length adjustment range when the angle is at the design angle position, when the angle deviates to the upper limit, the telescopic length range will be limited by the surrounding components, thereby causing the length adjustment range of the electric adjustable column to become smaller. Therefore, in order to ensure that when adjusting the length and angle of the electric adjustable column, the adjustment range of the electric adjustable column is maximized without interfering with the surrounding components, the preset angle range of the electric adjustable column in the embodiment of the present application can be -2.5° to 2.5°, and the preset length range can be 0 to 80 mm, that is, the safe adjustment range of the angle adjustment of the electric adjustable column is -2.5° to 2.5°, and the safe adjustment range of the length adjustment of the electric adjustable column is 0 to 80 mm.

[0062] Among them, the mapping relationship between the angle and length adjustment of the electric control column, the corresponding number and position of the Hall sensors corresponding to the angle adjustment, and the corresponding number and position of the Hall sensors corresponding to the length adjustment are shown in Table 1:

[0063] Table 1

[0064]

[0065]

[0066] For example, Figure 4 As shown, if a steering wheel length adjustment instruction is received from the user, the Hall sensor corresponding to the angle adjustment detects the angle position of the electric adjustment column based on the steering wheel length adjustment instruction, and determines whether the angle position of the electric adjustment column is within the preset angle range, that is, determines whether the angle position of the electric adjustment column is within the range of -2.5° to 2.5°. If the angle position of the electric adjustment column is within the range of -2.5° to 2.5°, it means that the angle position of the electric adjustment column is within the safe adjustment range of the angle adjustment, and the length motor can be directly driven to adjust the length of the electric adjustment column; if a steering wheel angle adjustment instruction is received from the user, the Hall sensor corresponding to the length adjustment detects the length position of the electric adjustment column based on the steering wheel angle adjustment instruction, and determines whether the length position of the electric adjustment column is within the preset length range, that is, determines whether the length position of the electric adjustment column is within the range of 0 to 80 mm. If the length position of the electric adjustment column is within the range of 0 to 80 mm, it means that the length position of the electric adjustment column is within the safe adjustment range of the length adjustment, and the angle motor can be directly driven to adjust the angle of the electric adjustment column.

[0067] In step S103, if the electrically adjustable column position is not within the preset adjustment range, the electrically adjustable column position is adjusted, and when the electrically adjustable column position is adjusted to the boundary of the preset coordinated adjustment range, the electrically adjustable column position is adjusted accordingly according to the pre-constructed electrically adjustable column angle-length adjustment mapping relationship.

[0068] Optionally, in one embodiment of the present application, judging whether the position of the electrically adjustable column is within a preset adjustment range based on the steering wheel adjustment instruction also includes: if the angle position of the electrically adjustable column is not within the preset angle range, and / or the length position of the electrically adjustable column is not within the preset length range, then determining that the position of the electrically adjustable column is not within the preset adjustment range.

[0069] Among them, the boundary of the preset coordinated adjustment range refers to the boundary of the optimized adjustment range of the electric adjustment column, that is, when the position of the electric adjustment column is adjusted to the boundary of the preset coordinated adjustment range, the angle and length of the electric adjustment column need to be coordinated adjusted at this time, and the boundary of the preset coordinated adjustment range may include a preset angle coordinated adjustment range boundary and a preset length coordinated adjustment range boundary, wherein the preset angle coordinated adjustment range boundary and the preset length coordinated adjustment range boundary can be set by technical personnel in this field according to actual design requirements, and can also be obtained through a limited number of computer simulations, and are not specifically limited here.

[0070] Specifically, if the Hall sensor corresponding to the angle adjustment detects that the angle position of the electric adjustment column is not within the preset angle range of -2.5° to 2.5°, and / or the Hall sensor corresponding to the length adjustment detects that the length position of the electric adjustment column is not within the preset length range of 0 to 80 mm, that is, the angle position of the electric adjustment column is not within the safe adjustment range of the angle adjustment, or the length position of the electric adjustment column is not within the safe adjustment range of the length adjustment, then it can be determined that the position of the electric adjustment column is not within the preset adjustment range, and it is necessary to further adjust the angle position of the electric adjustment column to within the preset angle range, or adjust the length position of the electric adjustment column to within the preset length range.

[0071] Optionally, in one embodiment of the present application, adjusting the position of the electrically adjustable tube column includes: if the angle position of the electrically adjustable tube column is not within a preset angle range, adjusting the angle of the electrically adjustable tube column to the preset angle range; if the length position of the electrically adjustable tube column is not within a preset length range, adjusting the length of the electrically adjustable tube column to the preset length range.

[0072] Specifically, Figure 5As shown, if the angle position of the electric adjustable pipe column is not within the preset angle range, it indicates that the angle position of the electric adjustable pipe column is not within the safe adjustment range of the angle adjustment. Therefore, the length motor cannot be directly driven to adjust the length of the electric adjustable pipe column. First, it is necessary to drive the angle motor to adjust the angle of the electric adjustable pipe column to the preset angle threshold. Similarly, if the length position of the electric adjustable pipe column is not within the preset length range, it indicates that the length position of the electric adjustable pipe column is not within the safe adjustment range of the length adjustment. Therefore, it is also impossible to directly drive the angle motor to adjust the angle of the electric adjustable pipe column. Instead, it is necessary to drive the length motor to adjust the length of the electric adjustable pipe column to the preset length threshold. After the angle of the electric adjustable pipe column is adjusted to the safe adjustment range of the angle adjustment, or the length of the electric adjustable pipe column is adjusted to the safe adjustment range of the length adjustment, the electric adjustable pipe column can be freely adjusted within the safe adjustment range. When the angle position of the electric adjustable pipe column or the length position of the electric adjustable pipe column is adjusted, and when the position of the electric adjustable pipe column is adjusted to the boundary of the preset coordinated adjustment range, that is, when the angle position of the electric adjustable pipe column is adjusted to the boundary of the preset angle coordinated adjustment range, or when the length position of the electric adjustable pipe column is adjusted to the boundary of the preset length coordinated adjustment range, in order to further improve the adjustment performance of the electric adjustable pipe column and avoid the angle adjustment of the electric adjustable pipe column exceeding the boundary of the preset angle coordinated adjustment range, or avoid the length adjustment of the electric adjustable pipe column exceeding the boundary of the preset length coordinated adjustment range, it is necessary to further adjust the position of the electric adjustable pipe column based on the mapping relationship between the angle and length adjustment of the electric adjustable pipe column. That is to say, when the position of the electric adjustable pipe column is adjusted to the boundary of the preset coordinated adjustment range, it is necessary to perform coordinated adjustment based on the angle and length of the electric adjustable pipe column, so that the position of the electric adjustable pipe column is always on the boundary of the preset coordinated adjustment range.

[0073] Preferably, the preset angle coordinated adjustment range of the electric adjustable tube column in the embodiment of the present application can be 0.5° to 2.5°, and the preset length coordinated adjustment range can be 60 to 80 mm. That is to say, when the angle position of the electric adjustable tube column is adjusted to the boundary of the preset angle coordinated adjustment range of 0.5° or 2.5°, it is necessary to perform coordinated adjustment based on the angle and length of the electric adjustable tube column. Or, when the length position of the electric adjustable tube column is adjusted to the boundary of the preset length coordinated adjustment range of 60mm or 80mm, it is necessary to perform coordinated adjustment based on the angle and length of the electric adjustable tube column to ensure that the position of the electric adjustable tube column is always on the boundary of the preset coordinated adjustment range.

[0074] For example, when receiving a steering wheel length adjustment command, if the Hall sensor corresponding to the angle adjustment detects that the angle of the electric adjustment column is 3°, which is not within the safe adjustment range of -2.5° to 2.5°, it is necessary to drive the angle motor to adjust the angle of the electric adjustment column to the preset angle threshold, that is, to adjust the angle of the electric adjustment column to -2.5° to 2.5°. At this time, the angle position of the electric adjustment column can be freely adjusted within the safe adjustment range of -2.5° to 2.5°. To avoid the angle adjustment of the electric adjustment column exceeding the boundary of the preset angle coordinated adjustment range, when the angle position of the electric adjustment column is adjusted to 0.5° or 2.5°, it is necessary to further adjust the position of the electric adjustment column based on the mapping relationship between the angle and length adjustment of the electric adjustment column, that is, to coordinate the adjustment based on the angle and length of the electric adjustment column, so that the position of the electric adjustment column is always on the boundary of the preset coordinated adjustment range.

[0075] Optionally, in one embodiment of the present application, the position of the electrically adjustable column is adjusted accordingly according to a pre-constructed mapping relationship of the electrically adjustable column angle-length adjustment, including: determining whether the slope of the electrically adjustable column angle-length is a preset target slope; if the slope of the electrically adjustable column angle-length is the preset target slope, constructing a mapping relationship of the electrically adjustable column angle-length adjustment based on the target slope.

[0076] The preset target slope may be set by those skilled in the art according to actual design requirements, or may be obtained through a limited number of computer simulations, and is not specifically limited here.

[0077] Specifically, in the embodiment of the present application, in order to ensure the precise adjustment of the electrically adjustable tube column, it is necessary to coordinately adjust the length and angle of the electrically adjustable tube column according to the slope K to ensure that the position of the electrically adjustable tube column is always at the boundary of the preset coordinated adjustment range.

[0078] Specifically, based on the above Table 1, it can be known that when the slope is the target slope (for example, 0.5), that is, the slope is not 0 or ∞, at this time, a mapping relationship of the electric control column angle-length adjustment is constructed based on the target slope, so as to adjust the position of the electric control column accordingly according to the mapping relationship of the electric control column angle-length adjustment constructed according to the target slope.

[0079] For example, when the slope is 0.5, the angle driving motor adjusts the position of the electric adjustable column to the boundary of the preset angle coordinated adjustment range, or the length driving motor adjusts the position of the electric adjustable column to the boundary of the preset length coordinated adjustment range. Since the changes in the length and angle of the electric adjustable column will affect the gap between it and the surrounding components, if only the length or angle of the electric adjustable column is adjusted separately, it may cause interference between the electric adjustable column and the surrounding components. Therefore, in order to avoid interference between the electric adjustable column and the surrounding components, it is necessary to combine the coordinated drive of the angle motor and the length motor to jointly adjust the position of the electric adjustable column, that is, when the slope is the target slope, the position of the electric adjustable column is adjusted accordingly based on the mapping relationship between the angle and length adjustment of the electric adjustable column, so that the electric adjustable column is always on the boundary of the preset coordinated adjustment range, so that the electric adjustable column always stays on the optimal boundary line of the adjustment range.

[0080] Optionally, in one embodiment of the present application, after determining whether the slope of the electric adjustment column angle-length is the preset target slope, it also includes: if the slope of the electric adjustment column angle-length is not the preset target slope, determining the target adjustment object and the target value of the target adjustment object according to the slope of the electric adjustment column angle-length, and adjusting the target adjustment object according to the target value, so that the angle and length of the electric adjustment column are within the boundary of the preset collaborative adjustment range.

[0081] Optionally, in one embodiment of the present application, the target adjustment object is determined according to the slope of the electric adjustment column angle-length, including: when the slope of the electric adjustment column angle-length is 0, the target adjustment object is the angle of the electric adjustment column; when the slope of the electric adjustment column angle-length is ∞, the target adjustment object is the length of the electric adjustment column.

[0082] Specifically, in an embodiment of the present application, if the slope of the angle-length of the electrically adjustable column is not the preset target slope, that is, the slope is 0 or ∞, the target adjustment object and the target value of the target adjustment object are further determined, wherein, when the slope of the angle-length of the electrically adjustable column is 0, the length change of the electrically adjustable column is always 0, so there is no need to adjust the length of the electrically adjustable column, and the target adjustment object is the angle of the electrically adjustable column. When the slope of the angle-length of the electrically adjustable column is ∞, the angle change of the electrically adjustable column is always 0, so there is no need to adjust the angle of the electrically adjustable column, and the target adjustment object is the length of the electrically adjustable column. That is to say, when the slope is 0, it is only necessary to drive the angle motor to adjust the angle of the electrically adjustable column, and when the slope is ∞, it is only necessary to drive the length motor to adjust the length of the electrically adjustable column, so that the angle and length of the electrically adjustable column are not only at the boundary of the preset coordinated adjustment range, but also improve the adjustment efficiency and adjustment stability.

[0083] Therefore, based on the specific discussion of the above-mentioned embodiments of the present application, the embodiments of the present application can, based on the steering wheel adjustment command given by the user, drive the corresponding angle motor to adjust the angle of the electric adjustable column to the preset angle range, or drive the length motor to adjust the length of the electric adjustable column to the preset length range when it is determined that the position of the electric adjustable column (angle position or length position) is not within the preset adjustment range. When the position of the electric adjustable column is adjusted to the boundary of the preset coordinated adjustment range, the position of the electric adjustable column is adjusted accordingly based on the mapping relationship of the electric adjustable column angle-length adjustment, so that the position of the electric adjustable column is always on the boundary of the preset coordinated adjustment range, thereby ensuring that the adjustment range of the electric adjustable column is maximized without interfering with surrounding components, while improving the design flexibility of the vehicle and the user's operating experience.

[0084] In summary, the embodiments of the present application can achieve the following beneficial effects:

[0085] (1) Freeing up adjustment space and improving user experience: By dynamically adjusting the length and angle of the electric control column, the adjustment space of the electric control column is freed up, avoiding the insufficient adjustment range caused by the limitations of surrounding components. At the same time, users can flexibly adjust the position (height and angle) of the steering wheel according to their own needs, improving driving comfort and convenience.

[0086] (2) Precise control to avoid interference: By adjusting the preset angle range, length range, and slope K in a coordinated manner, the electrically adjustable pipe string is ensured not to interfere with surrounding components during the adjustment process, thereby avoiding mechanical interference problems caused by an excessively large adjustment range and improving the safety and reliability of the system.

[0087] (3) Dynamic coordinated adjustment to optimize adjustment efficiency: The movement of the length motor and the angle motor is dynamically adjusted according to the slope K to ensure that the adjustment of the length and angle of the electrically adjustable pipe string is coordinated rather than independently performed. Thus, the coordinated adjustment optimizes the adjustment process and reduces the problem of low adjustment efficiency caused by adjusting the length or angle separately.

[0088] (4) Intelligent control to improve system performance: The Hall sensor is used to detect the changes in the angle and length of the electric control string in real time to achieve closed-loop control, ensuring that the adjustment process is accurate and correct. The system can automatically adjust the motor movement according to the current angle and length of the electric control string, thereby improving the intelligence level of the system.

[0089] In summary, according to the control method of the electric control column of the embodiment of the present application, when receiving the user's steering wheel adjustment command, it is determined whether the position of the electric control column is within the preset adjustment range based on the steering wheel adjustment command. If the position of the electric control column is not within the preset adjustment range, the position of the electric control column is adjusted, and when the position of the electric control column is adjusted to the boundary of the preset coordinated adjustment range, the position of the electric control column is adjusted accordingly according to the pre-constructed mapping relationship of the electric control column angle-length adjustment. This method can adjust the angle and / or length of the electric control column based on the number and position of the Hall sensors corresponding to different angles or lengths, thereby ensuring that the adjustment range of the electric control column is maximized without interfering with surrounding components, while improving the design flexibility of the vehicle and the user's operating experience.
