[0002] As users demand increasingly more intelligent and convenient features from their vehicles, steering wheel position adjustment is being implemented in a growing number of models. Users adjust the steering wheel mounted on the steering column by electrically adjusting its extension and angle. Current four-way electrically adjustable steering columns use two independent motors, one for extension and the other for angle adjustment. However, this control method results in a complex structure and high hardware and software requirements for electrically adjustable steering columns.

[0003] To address the aforementioned issues, existing technologies employ a single motor to simultaneously control the extension, retraction, and angle of the electrically adjustable steering column, thereby achieving four-way automatic steering wheel control. While this method significantly reduces the hardware and software requirements for the electrically adjustable steering column, the automatic electric steering column adjustment control relies on the confirmation of the slider's position, resulting in poor adjustment control performance.

[0062] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0063] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0064] The first embodiment of this application relates to an electrically adjustable steering column control method, such as... Figure 1 As shown, it includes:

[0065] Step 101: Judge the electric adjustable steering column according to the preset automatic adjustment judgment conditions and obtain the automatic control judgment result, wherein the electric adjustable steering column performs an initialization action in advance;

[0066] Step 102: When the automatic control judgment result indicates that the electric adjustable steering column meets the automatic adjustment judgment condition, an automatic operation signal is obtained;

[0067] Step 103: Based on the automatic operation signal and the preset mechanism position Hall number, the motor with integrated Hall sensor performs automatic control action on the electric adjustable steering column.

[0068] Specifically, such as Figure 2 As shown, the technical solution provided in this application automatically controls and judges the pre-initialized electric adjustable steering column or electro-electric adjustable steering column according to pre-set automatic control judgment conditions. When it is determined that the electric adjustable steering column meets the automatic adjustment judgment, the automatic control action of the steering column is executed according to the automatic operation signal.

[0069] It should be emphasized that the automatic control function in the electric steering column provided in this application is set according to user needs, and the automatic control adjustment judgment is also set according to user needs, which will not be elaborated here. For example, when the extension, retraction and angle changes of the electric steering column make it difficult for users to get in and out of the vehicle, the system installed on the vehicle obtains automatic control judgment conditions such as the power status of the electric steering column, the vehicle's gear engagement status, the opening and closing status of the steering wheels, and whether the user's seat belt is fastened to determine whether the vehicle can perform automatic adjustment of the electric steering column. Based on the automatic adjustment judgment conditions, the automatic control of the electric steering column is started or stopped, and the electric steering column is adjusted to its original position to facilitate the user's entry and exit from the vehicle.

[0070] In the technical solution provided in this application, the motor integrates a Hall sensor. The Hall sensor signal changes periodically with the rotation of the motor. For example, when the motor rotates one revolution, the Hall sensor signal changes for one cycle. The controller records the number of cycles of the Hall sensor signal change, i.e., the Hall number.

[0071] Furthermore, the technical solution provided in this application can also control the electric adjustment of the steering column based on signals sent by the user manually controlling the vehicle buttons.

[0072] For example, after the adjustment controller receives a vehicle signal, it first determines whether an initialization signal has been received. If an initialization signal is received, the electric steering column controller performs an initialization action on the electric steering column control system. If no initialization signal is received, it determines whether a manual button control signal has been received. If a manual button control signal is received, the adjustment controller performs the corresponding action on the electric steering column control system according to the manual button control signal, thereby controlling the vehicle's steering wheel. If no manual button control signal is received, it determines whether the electric steering column control system meets the automatic adjustment preset conditions. If the automatic adjustment preset conditions are met, the corresponding automatic adjustment preset action is executed. When the electric steering column controller does not receive either the initialization signal or the manual button control signal, and the electric steering column control system does not meet the automatic adjustment preset conditions, the adjustment controller does not perform any control action on the electric steering column control system.

[0073] Among them, the manual button control signal has a higher priority than the initialization signal, which in turn has a higher priority than the automatic adjustment signal. When the adjustment controller receives the manual button control signal, the initialization signal, and the automatic adjustment signal at the same time, it will respond to the manual button control signal first and control the electric adjustment steering column.

[0074] Based on the above implementation method, since the electric adjustment steering column is independently memorized and controlled by Hall effect data, and the motor action is accurately recorded by the number of motor revolutions corresponding to the number of periodic changes in the Hall sensor, the electric adjustment steering column has a good control effect.

[0075] Based on the above implementation methods, such as Figure 3 As shown, in the electric adjustable steering column control method provided in this application, before step 101, the method further includes:

[0076] Step 104: Obtain the initialization signal;

[0077] Step 105: According to the initialization signal, the telescopic adjustment mechanism of the electric adjustable steering column is adjusted to the upper limit of telescopic movement by the adjustment controller, and the upper limit Hall number of the motor is initialized.

[0078] Step 106: According to the initialization signal, the telescopic adjustment mechanism of the electric adjustable steering column is adjusted to the lower limit of telescopic movement by the adjustment controller, and the Hall sensor is used to assign a value to the lower limit Hall number of the motor.

[0079] Specifically, such as Figure 4 As shown, before implementing the electric adjustable steering column control method, the technical solution provided in this application can also initialize the steering column. When the electric adjustable steering column control system corresponding to the electric adjustable steering column control method receives the initialization signal transmitted by the vehicle, it adjusts the extension / retraction adjustment mechanism of the steering column to the mechanical upper limit of the electric adjustable steering column control system via the adjustment controller or the electric adjustable steering column controller. It then performs an initialization action on the extension / retraction upper limit Hall number of the motor controlling the electric adjustable steering column at this time, setting the position adjusted to the mechanical upper limit to zero. For example, the extension / retraction adjustment mechanical limit Hall number used to control the upper limit of the electric adjustable steering column in the electric adjustable steering column control system can be assigned a value of 0.

[0080] Subsequently, the telescopic adjustment mechanism of the steering column is adjusted to the mechanical lower limit of the electric adjustable steering column control system by adjusting the controller or the electric adjustable steering column controller, and the lower limit Hall number of the telescopic adjustment motor that controls the electric adjustable steering column at this time is assigned a value, for example, the Hall number in the Hall sensor integrated in the motor at this time is assigned to the lower limit Hall number of the telescopic adjustment mechanical limit.

[0081] After the upper limit Hall number and lower limit Hall number of the telescopic adjustment mechanical limit are assigned, the adjustment controller can control the motor to run the corresponding number of revolutions according to the pre-entered Hall number. The motor drives the telescopic adjustment mechanism to the predetermined position, and the electric adjustment steering column is controlled by the telescopic adjustment mechanism to realize the automatic operation of the electric adjustment steering column, thereby realizing the memory and control action of the electric adjustment steering column.

[0082] Furthermore, considering the inherent delay and error in the electric adjustable steering column, the electric adjustable steering column control method provided in this application, in addition to initializing the upper limit Hall number and lower limit Hall number of the telescopic adjustment mechanical limit, also adds a certain number of Halls, for example, from 5 to 10, to the upper limit Hall number of the telescopic adjustment software limit and assigns them to the upper limit Hall number of the telescopic adjustment software limit, and reduces a certain number of Halls, for example, from 5 to 10, to the lower limit Hall number of the telescopic adjustment software limit. In the electric adjustable steering column control method provided in this application, the lower limit Hall number of the telescopic adjustment mechanical limit is obtained by increasing the Hall number by a few Hall numbers to obtain the lower limit Hall number of the telescopic adjustment software limit, and the upper limit Hall number of the telescopic adjustment mechanical limit is obtained by decreasing the Hall number by a few Hall numbers to obtain the upper limit Hall number of the telescopic adjustment software limit. At this time, the movement amplitude of the electric adjustable steering column controlled by the software is less than the mechanical limit position of the electric adjustable steering column. This avoids the problem of damage to the structure of the steering column and reduced service life of the parts when the steering column reaches the mechanical limit when the system manually controls the electric adjustable steering column according to the user's instructions.

[0083] Based on the above implementation method, by initializing and setting the upper and lower limits of the telescopic adjustment mechanism, the motor stalling caused by frequent adjustments to the telescopic mechanical limit during use can be avoided, which would affect the motor's lifespan.

[0084] Based on the above implementation methods, such as Figure 5 As shown, in the electric adjustable steering column control method provided in this application, after step 104, it further includes:

[0085] Step 107: Based on the initialization signal, control the electric adjustable steering column angle adjustment mechanism to adjust to the upper limit angle by adjusting the controller and perform an initialization action on the upper limit Hall number of the motor angle;

[0086] Step 108: Based on the initialization signal, the angle adjustment mechanism of the electric adjustable steering column is adjusted to the lower limit of the angle by the adjustment controller, and the lower limit Hall value of the motor is assigned according to the Hall sensor.

[0087] Specifically, before implementing the electric adjustable steering column control method, the technical solution provided in this application can also initialize the adjustable steering column. When the electric adjustable steering column control system corresponding to the electric adjustable steering column control method receives the initialization signal transmitted by the vehicle, while initializing the corresponding data of the telescopic mechanism through the adjustment controller, the angle adjustment mechanism of the steering column is adjusted to the mechanical upper limit of the electric adjustable steering column control system through the adjustment controller or the electric adjustable steering column controller. At this time, the upper limit Hall number of the angle adjustment mechanism of the motor controlling the electric adjustable steering column is initialized, setting the position adjusted to the mechanical upper limit to zero. For example, the upper limit Hall number of the angle adjustment mechanical limit used to control the upper limit of the electric adjustable steering column in the electric adjustable steering column control system can be assigned a value of 0.

[0088] Subsequently, the steering column angle adjustment mechanism is adjusted to the mechanical lower limit of the electric steering column control system by adjusting the controller or the electric steering column adjustment controller, and the lower limit Hall number of the angle of the motor controlling the electric steering column at this time is assigned a value, for example, the lower limit Hall number of the angle adjustment mechanical limit is assigned according to the Hall number in the Hall sensor integrated in the motor at this time.

[0089] After the upper limit Hall number and lower limit Hall number of the angle adjustment mechanical limit are assigned, the adjustment controller can control the motor to run the corresponding number of revolutions according to the pre-entered Hall number. The motor drives the angle adjustment mechanism to the predetermined position, and the electric adjustment steering column is controlled by the angle adjustment mechanism to realize the automatic operation of the electric adjustment steering column, thereby realizing the memory and control action of the electric adjustment steering column.

[0090] Furthermore, considering the inherent delay and error in the electric adjustable steering column, the electric adjustable steering column control method provided in this application, in addition to initializing the upper limit Hall number and lower limit Hall number of the angle adjustment mechanical limit, also adds a certain number of Halls based on the upper limit Hall number of the angle adjustment mechanical limit, for example, from 5 to 10 Halls and assigns them to the upper limit Hall number of the angle adjustment software limit, and reduces a certain number of Halls based on the lower limit Hall number of the angle adjustment mechanical limit, for example, from 5 to 10 Halls and assigns them to the lower limit Hall number of the angle adjustment software limit.

[0091] It should be emphasized that the initialization actions of the relevant parameters of the telescopic mechanism and the angle mechanism in the electric adjustable steering column control method provided in this application can be performed simultaneously. That is, after the adjustment controller controls the motor to achieve the initialization and zeroing action after the telescopic mechanism and the angle mechanism reach the upper mechanical limit, the motor simultaneously assigns the Hall number value after the telescopic mechanism and the angle mechanism reach the lower mechanical limit. Alternatively, the initialization actions of the telescopic mechanism and the angle mechanism can be performed separately according to user needs. This application does not impose any restrictions.

[0092] Based on the above implementation method, by initializing and setting the upper and lower limits of the angle adjustment mechanism, the motor stalling caused by frequent adjustments to the mechanical limit during use can be avoided, which would affect the motor's lifespan.

[0093] Based on the above embodiments, the mechanism position Hall number includes the telescopic adjustment mechanism position Hall number, such as... Figure 6 As shown, in the electric adjustable steering column control method provided in this application, before step 103, the method further includes:

[0094] Step 109: Control the telescopic adjustment mechanism to perform a memory action via the adjustment controller;

[0095] Step 110: When the transmission clutch mechanism corresponding to the telescopic adjustment mechanism is in the engaged state, record the effective telescopic operation Hall count of the motor;

[0096] Step 111: Obtain the position Hall number of the telescopic adjustment mechanism based on the effective telescopic operation Hall number.

[0097] Specifically, such as Figure 7 As shown, when the steering column controller reads signals such as the motor start / stop signal, the motor Hall sensor signal, and the clutch signal of the telescopic adjustment mechanism in the transmission clutch mechanism, it controls the telescopic adjustment mechanism to perform the control action of independently memorizing the position of the electric steering column. At this time, the operating status of the motor and the engagement / disengagement status of the clutch mechanism of the telescopic adjustment mechanism in the transmission clutch mechanism are obtained based on the above signals. When the motor is in the starting state and the clutch mechanism of the telescopic adjustment mechanism in the transmission clutch mechanism is in the engaged state, the Hall count of the motor's telescopic operation during this state duration is recorded, for example, the effective operating Hall count of the telescopic adjustment motor is recorded, and the position Hall count of the telescopic adjustment mechanism is obtained based on these effective operating Hall counts of the telescopic adjustment motor, for example, by accumulating the recorded Hall counts to obtain the position Hall count of the telescopic adjustment mechanism. Subsequently, the effective operating Hall count of the telescopic adjustment motor is reset to zero. The zeroed effective operating Hall count of the telescopic adjustment motor is used to re-record the new telescopic adjustment position independently memorized parameters. The previously obtained position Hall count of the telescopic adjustment mechanism is used by the adjustment controller to execute corresponding actions on the telescopic adjustment mechanism through the motor.

[0098] Based on the above embodiments, since the technical solution provided by this application can obtain the corresponding telescopic adjustment mechanism position Hall number under the premise of meeting the operating requirements of the telescopic adjustment mechanism, it is convenient for the adjustment controller to control the motor according to the recorded telescopic adjustment mechanism position Hall number, thereby realizing the telescopic mechanism memory and control function of the electric adjustment steering column.

[0099] Based on the above embodiments, the mechanism position Hall number also includes the angle adjustment mechanism position Hall number, such as... Figure 8 As shown, in the electric adjustable steering column control method provided in this application, before step 103, the method further includes:

[0100] Step 112: Control the angle adjustment mechanism to perform a memory action via the adjustment controller;

[0101] Step 113: When the transmission clutch mechanism corresponding to the angle adjustment mechanism is in the engaged state, record the effective operating Hall effect count of the motor angle;

[0102] Step 114: Obtain the position Hall number of the angle adjustment mechanism based on the effective operating Hall number of the angle.

[0103] Specifically, after the steering column controller reads signals such as the motor start / stop signal, the motor Hall sensor signal, and the clutch signal of the angle adjustment mechanism in the transmission clutch mechanism, it controls the angle adjustment mechanism to execute the control action of independently memorizing the position of the electric steering column. At this time, the operating status of the motor and the engagement / disengagement status of the clutch mechanism of the angle adjustment mechanism in the transmission clutch mechanism are obtained based on the above signals. When the motor is in the running state and the clutch mechanism of the angle adjustment mechanism in the transmission clutch mechanism is in the engaged state, the Hall count of the motor's angle operation during this state duration is recorded, for example, the effective operating Hall count of the angle-adjusted motor is recorded, and the position Hall count of the angle adjustment mechanism is obtained based on these effective operating Hall counts of the angle-adjusted motor, for example, by accumulating the recorded Hall counts to obtain the position Hall count of the angle adjustment mechanism. Subsequently, the effective operating Hall count of the angle-adjusted motor is reset to zero. The zeroed effective operating Hall count of the angle-adjusted motor is used to re-record the new angle adjustment position independently memorized parameters. The previously obtained position Hall count of the angle adjustment mechanism is used by the adjustment controller to execute corresponding actions on the angle adjustment mechanism through the motor.

[0104] It should be emphasized that in the electric adjustable steering column control method provided in this application, the positions of the telescopic mechanism and the angle mechanism can be independently memorized simultaneously or separately according to user needs, and this application does not impose any restrictions.

[0105] Based on the above embodiments, since the technical solution provided by this application can obtain the corresponding angle adjustment mechanism position Hall number under the premise of meeting the operating requirements of the angle adjustment mechanism, it is convenient for the adjustment controller to control the motor according to the recorded angle adjustment mechanism position Hall number, thereby realizing the angle mechanism memory and control function of the electric adjustment steering column.

[0106] Based on the above implementation methods, such as Figure 9 As shown, in the electric adjustable steering column control method provided in this application, after step 103, it further includes:

[0107] Step 115: Perform a motor stall detection on the motor and obtain the motor stall detection result;

[0108] Step 116: When the motor stall judgment result is that the motor is stalled, perform an initialization action on the electric adjustable steering column.

[0109] Specifically, the electric adjustable steering column control method provided in this application also performs motor stall detection. When motor stall is detected, the electric adjustable steering column is controlled to perform initialization actions to eliminate the fault.

[0110] It is important to emphasize that the motor stall detection provided in this application is not limited to automatically controlling the electric steering column to adjust the steering wheel position according to preset commands, but can also detect when the user controls the steering wheel position via buttons on the vehicle. Furthermore, to improve visibility, the electric steering column control method provided by the device itself can output and display abnormal results for the user to view.

[0111] Based on the above implementation method, the electric adjustable steering column control method provided in this application can automatically re-initialize the motor during the detection and adjustment process if the motor stalls, thus repairing the position memory and adjustment abnormalities caused by the deviation between the Hall number and the actual position after long-term use.
