Description

Technical Field

[0001] This disclosure relates to the field of vehicle steering technology, and more particularly to a control method for an electronically controlled steering column, electronic equipment, and a vehicle. Background Technology

[0002] With the rapid increase in demand for intelligent driving and cabin comfort, electrically adjustable steering columns (hereinafter referred to as EPCs) have become standard equipment in passenger vehicles. Drivers want to be able to adjust the steering wheel to the optimal driving position after taking their seats by adjusting the EPC. Therefore, OEMs generally place EPC switches on the steering wheel, dashboard, or next to the seat, sending commands to the domain controller via a bus to drive the motor to adjust the EPC.

[0003] Currently, using a fixed button only allows for fixing the drive duration of the ESC (Electronic Speed ​​Controller) column. For example, each button press causes the domain controller to adjust the ESC column by a certain length or angle according to the corresponding drive duration. This method cannot provide high-precision or continuous adjustment of the ESC column based on user needs, resulting in a poor user experience. Summary of the Invention

[0004] To address the aforementioned technical problems, this disclosure provides a control method, apparatus, electronic device, and vehicle for an electrically adjustable column.

[0005] A first aspect of this disclosure provides a method for controlling an electrically adjustable column, comprising: The rolling direction and rolling rate of the target wheel in the steering wheel within a preset time are determined, where the rolling rate characterizes the speed at which the target wheel rolls. Then, the adjustment type of the target wheel and the corresponding adjustment direction of the rolling direction under that adjustment type are determined. Based on a preset correspondence between rolling rate and drive duration, the target drive duration of the adjustment motor corresponding to the rolling rate is determined. The rolling rate and the drive duration of the adjustment motor are positively correlated. Finally, the adjustment motor can be controlled to adjust the ESC (Electronic Speed ​​Regulator) column according to the target drive duration, adjustment type, and adjustment direction. This allows for continuous adjustment of the ESC column when the user slides the wheel quickly, increasing the drive duration when the user slides the wheel slowly, and precise adjustment when the user slides the wheel slowly, thus meeting user needs and improving the user experience.

[0006] In some possible implementations, the target roller is an angle adjustment roller, and the control adjustment motor adjusts the ESC column according to the target drive duration, the adjustment type, and the adjustment direction, including: When the target roller is rolling upwards, the control angle adjustment motor reduces the angle between the ESC column and the horizontal plane according to the target drive duration; When the target roller is rolling downwards, the control angle adjustment motor increases the angle between the ESC column and the horizontal plane according to the target drive duration.

[0007] In some possible implementations, the target roller is a length adjustment roller, and the control adjustment motor adjusts the ESC column according to the target drive duration, adjustment type, and adjustment direction, including: When the target roller rolls upwards, the control length adjustment motor adjusts the ESC column along the extension direction of the ESC column according to the target drive duration; When the target roller is rolling downwards, the control length adjustment motor adjusts the ESC column in the direction of shortening of the ESC column according to the target drive duration.

[0011] In some possible implementations, stopping the adjustment of the electrically controlled column includes: Continuously monitor the contact area and duration between the palm and the steering wheel; If the hand does not grip the steering wheel within a preset time period determined based on the contact area, then the adjustment of the ESC column will stop.

[0012] In some possible implementations, when the target roller is detected to include an angle adjustment roller and a length adjustment roller, the adjustment direction and rolling speed of the angle adjustment roller and the length adjustment roller are determined respectively. Based on the preset relationship between rolling rate and driving time, the target driving time for the angle adjustment roller and the length adjustment roller is determined respectively. The angle adjustment motor and the length adjustment motor are controlled to perform a combined adjustment of the angle and length of the ESC column according to their respective target drive duration, adjustment type and adjustment direction.

The rolling rate and the driving time of the regulating motor are positively correlated. The control unit is used to control the regulating motor to adjust the ESC column according to the target drive duration, adjustment type, and adjustment direction.

[0014] In some possible implementations, the target roller is an angle adjustment roller, and the control unit is specifically used for: When the target roller is rolling upwards, the control angle adjustment motor reduces the angle between the ESC column and the horizontal plane according to the target drive duration; When the target roller is rolling downwards, the control angle adjustment motor increases the angle between the ESC column and the horizontal plane according to the target drive duration.

[0015] In some possible implementations, the target roller length adjustment roller, control unit, is specifically used for: When the target roller rolls upwards, the control length adjustment motor adjusts the ESC column along the extension direction of the ESC column according to the target drive duration; When the target roller is rolling downwards, the control length adjustment motor adjusts the ESC column in the direction of shortening of the ESC column according to the target drive duration.

[0018] In some possible implementations, the device further includes: The stop unit is used to obtain the vehicle's driving speed. If the driving speed is greater than or equal to a threshold speed, the adjustment of the ESC column is stopped.

[0019] In some possible implementations, the stopping unit is specifically used for: Continuously monitor the contact area and duration between the palm and the steering wheel; If the hands do not grip the steering wheel within the preset time period determined based on the contact area, then the adjustment of the ESC column will stop.

[0020] In some possible implementations, the control unit is specifically used for: When the target roller is detected to include an angle adjustment roller and a length adjustment roller, the adjustment direction and rolling speed of the angle adjustment roller and the length adjustment roller are determined respectively. Based on the preset relationship between rolling rate and driving time, the target driving time for the angle adjustment roller and the length adjustment roller is determined respectively. The angle adjustment motor and the length adjustment motor are controlled to perform a combined adjustment of the angle and length of the ESC column according to their respective target drive duration, adjustment type and adjustment direction.

[0024] A sixth aspect of this disclosure provides a vehicle that includes electronic equipment provided in the third aspect.

[0025] The technical solution provided in this disclosure has the following advantages: The control method, device, electronic equipment, and vehicle for the ESC (Electronic Speed ​​Regulator) column provided in this disclosure can first determine the rolling direction of the target roller in the steering wheel and its rolling rate within a preset time. The rolling rate characterizes the speed at which the target roller rolls. Then, the adjustment type of the target roller and the adjustment direction corresponding to the rolling direction under the adjustment type can be determined. Based on a preset correspondence between the rolling rate and the driving duration, the target driving duration of the adjustment motor corresponding to the rolling rate is determined. The rolling rate and the driving duration of the adjustment motor are positively correlated. Finally, the ESC column can be adjusted according to the target driving duration, adjustment type, and adjustment direction by controlling the adjustment motor. Furthermore, in this application, the driving duration of the corresponding ESC column can be determined based on the frequency at which the user rolls the target roller. Thus, when the user slides the roller quickly, the driving duration of the ESC column can be increased to achieve continuous adjustment of the ESC column. When the user slides the roller slowly, the driving duration of the ESC column can be reduced to achieve precise adjustment of the ESC column at slow speeds, thereby meeting user needs and improving the user experience.

[0029] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0034] The electrically adjustable steering column, or ESC for short, is a key component of a car's steering system. Driven by an electric motor, it enables electric adjustment of the steering wheel angle and height, allowing the driver to adjust the steering wheel position according to their needs, thereby improving driving comfort and convenience.

[0035] With the rapid increase in demand for intelligent driving and cabin comfort, electrically adjustable steering columns (hereinafter referred to as EPCs) have become standard equipment in passenger vehicles. Drivers want to be able to adjust the steering wheel to the optimal driving position after taking their seats by adjusting the EPC. Therefore, OEMs generally place fixed buttons on the steering wheel, dashboard, or next to the seat as EPC switches, which send commands to the domain controller via a bus to drive the motor to adjust the EPC.

[0036] Currently, using a fixed button only allows for fixing the drive duration of the ESC (Electronic Speed ​​Controller) column. For example, each button press causes the domain controller to adjust the ESC column by a certain length or angle according to the corresponding drive duration. This method cannot provide high-precision or continuous adjustment of the ESC column based on user needs, resulting in a poor user experience.

[0037] In view of this, embodiments of this application provide a control method for an electrically adjustable column, comprising: First, the rolling direction and rolling rate of the target wheel in the steering wheel within a preset time can be determined. The rolling rate characterizes how fast the target wheel rolls. Then, the adjustment type of the target wheel and the corresponding adjustment direction of the rolling direction under the adjustment type can be determined. Based on the preset correspondence between the rolling rate and the driving time, the target driving time of the adjustment motor corresponding to the rolling rate can be determined. The rolling rate and the driving time of the adjustment motor are positively correlated. Finally, the control motor can be used to adjust the ESC column according to the target driving time, adjustment type, and adjustment direction. In this application, the driving time of the corresponding ESC column can be determined according to the frequency of the user's rolling of the target wheel. When the user slides the wheel quickly, the driving time of the ESC column can be increased to achieve continuous adjustment of the ESC column. When the user slides the wheel slowly, the driving time of the ESC column can be reduced to achieve precise adjustment of the ESC column at slow speeds, thereby meeting user needs and improving the user experience.

[0038] The method will be described below with reference to specific embodiments.

[0039] Figure 1 This is a flowchart of a control method for an ESC (Electronic Speed ​​Regulator) column provided in an embodiment of this disclosure. The method can be executed by a control device for the ESC column, which can be implemented in software and / or hardware. The control device for the ESC column can be configured in an electronic device, such as a server or terminal. Specifically, the terminal includes an in-vehicle terminal, a computer, or a tablet computer. The following example illustrates the execution of the method provided in this application in a vehicle domain controller.

[0040] like Figure 1 As shown, the control method for the electronically controlled steering column provided in this disclosure can be applied to the field of electronically controlled steering column adjustment technology. For example, it can be used to adjust the electronically controlled steering column according to the driving duration of the rollers in the steering wheel. The control method for the electronically controlled steering column may include the following steps.

[0041] S101. Determine the rolling direction of the target roller in the steering wheel and the rolling rate within a preset time.

[0042] When the steering wheel adjustment function is enabled, the domain controller can identify whether the scroll wheel in the steering wheel is slipping. If it is determined that the scroll wheel in the steering wheel is slipping, it can determine the rolling direction of the target scroll wheel.

[0043] For example, such as Figure 2A As shown, with Figure 2A Taking a steering wheel with two rollers, roller A and roller B, as an example, the target roller is the roller that slides. For example, if the user slides roller A, then roller A can be the target roller; if the user slides roller B, then roller B can be the target roller.

[0044] The domain controller can determine whether the target scroll wheel is rolling upwards or downwards. In some possible implementations, rolling upwards can refer to the counterclockwise direction when the steering wheel is straight, i.e., the scroll wheel rolls along the directions of nuts a and b. Rolling downwards refers to the clockwise direction when the steering wheel is straight (meaning the steering wheel is back in the straight position, at which point the front wheels point straight ahead, the steering angle is zero, and the vehicle can maintain straight-line driving), i.e., the scroll wheel rolls along the directions of icons c and d.

[0045] It should be noted that the position of the scroll wheel may change due to variations in the steering wheel's rotation angle. In some possible implementations, the direction of the scroll wheel's upward or downward movement may not change with the steering wheel's rotation angle, for example... Figure 2B As shown, if the steering wheel is rotated 90 degrees to the right, the scroll wheel can still be rotated counterclockwise when the steering wheel is straight, with the counterclockwise direction being the upward scrolling direction. For example... Figure 2C As shown, when the steering wheel is rotated 180 degrees to the right, even though the roller has rotated 180 degrees, the upward rolling direction can still be determined by the counterclockwise direction of the roller when the steering wheel is straight.

[0046] In some possible implementations, the scrolling direction vertically upward along the horizontal plane can be defined as upward scrolling, and the scrolling direction vertically downward along the horizontal plane can be defined as downward scrolling. This way, the user does not need to worry about how the steering wheel is tilted; simply turning it up or down will move the wheel up or down, making it more convenient for the user and improving the user experience.

[0047] The domain controller can also determine the scrolling rate within a preset time period, where the scrolling rate can be used to characterize how fast the target scroll wheel scrolls. The preset time could be, for example, 50ms. This is just an example; those skilled in the art can set the value of the preset time according to actual needs, and this is not a limitation.

[0048] S102. Determine the adjustment type of the target roller and the adjustment direction corresponding to the rolling direction under the adjustment type.

[0049] The domain controller can determine the type of adjustment for the target roller.

[0050] For example, one scroll wheel can correspond to one type of adjustment, such as Figure 2AAs shown, roller A corresponds to angle adjustment, and roller B corresponds to length adjustment. Angle adjustment refers to the angle motor driving the column support to rotate around a fixed hinge point via a worm gear pair, thereby changing the pitch angle between the column axis and the horizontal plane, achieving precise control of the steering wheel's tilt. Length adjustment refers to the length motor driving the outer tube of the column to slide back and forth along its axis via a lead screw-nut or gear-rack mechanism, thereby changing the steering wheel's fore-and-aft position relative to the driver.

[0051] For example, if a user wants to adjust the steering wheel angle, they can slide roller A to drive the angle adjustment motor to adjust the angle of the ESC column, thus adjusting the steering wheel angle. If a user wants to adjust the steering wheel length, they can slide roller B to drive the length adjustment motor to adjust the length of the ESC column.

[0052] The domain controller can determine the adjustment direction corresponding to the scrolling direction under the adjustment type. That is, the adjustment direction of the ESC column can be different for different scrolling directions of the target roller.

[0053] S103. Based on the preset correspondence between rolling rate and driving time, determine the target driving time of the adjustment motor corresponding to the rolling rate.

[0054] After determining the rolling rate of the target roller within a preset time, the domain controller determines the target drive duration of the motor corresponding to the rolling rate based on the preset correspondence between the rolling rate and the drive duration. That is, different rolling rates may correspond to different drive durations. The domain controller can determine the target drive duration of the ESC column corresponding to the rolling rate. The rolling rate can be positively correlated with the drive duration.

[0055] S104. Control the motor to adjust the ESC column according to the target drive duration, adjustment type and adjustment direction.

[0056] After determining the target drive duration, adjustment type, and adjustment direction, the domain controller can control the adjustment motor to adjust the ESC column according to the target drive duration, the adjustment type, and the adjustment direction.

[0057] In this embodiment, the ECU can first determine the rolling direction of the target wheel in the steering wheel and the rolling rate within a preset time. The rolling rate is used to characterize the speed at which the target wheel rolls. Then, it can determine the adjustment type of the target wheel and the adjustment direction corresponding to the rolling direction under the adjustment type. Based on the preset correspondence between the rolling rate and the driving time, it can determine the target driving time of the adjustment motor corresponding to the rolling rate. The rolling rate and the driving time of the adjustment motor are positively correlated. Finally, it can adjust the ESC column according to the target driving time, adjustment type, and adjustment direction by controlling the adjustment motor. In this application, the driving time of the corresponding ESC column can be determined according to the frequency of the user's rolling of the target wheel. In this way, when the user slides the target wheel quickly, the driving time of the ESC column can be increased to achieve continuous adjustment of the ESC column. That is, when the user slides the target wheel quickly, the ECU can map the fast rolling rate to a longer target driving time, so that the adjustment motor can continuously output within the target driving time. This can connect multiple micro-steps that should be separate into a continuous displacement without steps, thereby achieving continuous adjustment. When the user slowly slides the target scroll wheel, the drive time of the ESC (Electronic Speed ​​Regulator) column can be reduced, enabling precise adjustment of the ESC column at slow speeds. Specifically, when the user slowly slides the target scroll wheel, the ECU maps the slow scrolling rate to a shorter target drive time. The regulating motor only lightly pushes the ESC column within a very short window, causing only a slight displacement each time. This breaks down continuous long commands into micro-steps that can be corrected point by point, achieving precise adjustment at slow speeds. This allows for precise or continuous adjustment based on user needs, thereby improving the user experience.

[0058] The above embodiment is the first embodiment. The second embodiment is described below. The second embodiment provides another control method for the electrically controlled column, such as... Figure 3 As shown, it specifically includes: S301. Determine the rolling direction of the target roller in the steering wheel and obtain the number of times the rolling signal is received within a preset time. Determine the rolling rate within the preset time based on the number of times the rolling signal is received.

[0059] The domain controller can determine the direction of rotation of the target wheel in the steering wheel.

[0060] This step is similar in principle to that in the first embodiment, and will not be described in detail here.

[0061] The domain controller can obtain the number of scroll signals received within a preset time and determine the scroll rate within the preset time based on the number of scroll signals received.

[0062] For example, consider a steering wheel scroll wheel with a radius of 8.5mm and a sliding angle of 120 degrees. Each time the scroll wheel rotates a preset angle (e.g., 18 degrees), a signal is triggered. Therefore, one full rotation in one direction (which can be simply described as one rotation in one direction), i.e., a 120-degree rotation in one direction, will trigger 7 signals. The specific formula is as follows: ; Where f is the number of signals that can be triggered corresponding to the angle that the finger can slide in a single stroke, b is the angle that the hand can slide, and c is the angle at which a signal is triggered once.

[0063] Once the number of times the rolling signal is received within a preset time is determined, the rolling rate within the preset time can be determined based on the number of times the rolling signal is received.

[0064] S302. Determine the adjustment type of the target roller as angle adjustment and the angle adjustment direction corresponding to the rolling direction under angle adjustment.

[0065] The domain controller can determine that the adjustment type of the target scroll wheel is angle adjustment. For example, such as Figure 2A As shown, the adjustment type corresponding to roller A is angle adjustment. For example, if a user wants to adjust the steering wheel angle, they can slide roller A to drive the angle adjustment motor to adjust the angle of the ESC column, thereby achieving steering wheel angle adjustment.

[0066] The domain controller determines the adjustment direction corresponding to the scrolling direction under angle adjustment. It should be noted that the angle adjustment direction may be different for different scrolling directions.

[0067] For example, if the target roller is an angle adjustment roller and the scrolling direction is upward, the corresponding adjustment direction can be the direction that raises the steering wheel height. That is, the angle adjustment motor can be controlled to increase the angle between the ESC column and the horizontal plane according to the target angle and target drive duration.

[0068] For example, if the target roller is an angle adjustment roller and the scrolling direction is downward, the corresponding adjustment direction can be adjusted to lower the steering wheel height. This means the angle adjustment motor can be controlled to reduce the angle between the ESC column and the horizontal plane according to the target drive duration.

[0069] S303. Based on the preset correspondence between rolling rate and driving duration, determine the target driving duration of the angle adjustment motor corresponding to the rolling rate.

[0070] The domain controller can determine the target drive duration of the motor by adjusting the angle corresponding to the scrolling rate based on the preset correspondence between the scrolling rate and the drive duration.

[0071] For example, the relationship between rolling rate and motor drive duration can be shown in the following table:

[0072] It should be noted that one scroll of the target scroll wheel means one signal is triggered. That is, two scrolls within 50ms means that the target scroll wheel triggers two signals within 50ms, and the domain controller receives two signals within 50ms.

[0073] In some possible implementations, the ECU can determine the target regulating current of the ESC column corresponding to the rolling rate based on the preset correspondence between the rolling rate and the drive current.

[0074] For example, the relationship between rolling rate and driving current can be shown in the following table:

[0075] After determining the target adjustment current, the target drive duration of the ESC corresponding to the target drive current can be determined according to the preset correspondence between drive current and drive duration. The ESC can then be controlled to adjust the angle of the ESC according to the target drive current, the corresponding target drive duration, and the adjustment direction corresponding to the rolling direction.

[0076] For example, the relationship between motor drive current and motor drive duration can be shown in the table below:

[0077] For example, such as Figure 4 As shown, when the user moves roller A, its pulse signal can be transmitted to the domain controller via the Page1SwtSts or PageRSwtSts signal lines of the combination switch. The rolling direction of the target roller can be transmitted to the domain controller via the VRSwtSts signal line of the combination switch. For example, if the target roller rolls upwards, the signal received by the domain controller can be the RiSdeUpRollSts signal; if the target roller rolls downwards, the signal received by the domain controller can be the RiSdeDoRollSts signal. The domain controller can determine the target drive current of the ESC corresponding to the rolling rate based on the preset correspondence between the rolling rate and the drive current. Then, based on the preset correspondence between the drive current and the drive duration, it can determine the target drive duration of the ESC corresponding to the target drive current and output the corresponding target drive current to the angle adjustment motor. The angle adjustment motor can have a built-in Hall signal for real-time closed-loop control to control the ESC to adjust the angle according to the target drive duration and the adjustment direction corresponding to the rolling direction based on the target drive current.

[0078] This allows the target drive duration of the motor to be adjusted based on the preset relationship between the rolling rate and the drive duration.

[0079] S304. The control angle adjustment motor adjusts the angle of the ESC column according to the target drive duration, adjustment type, and adjustment direction.

[0080] The domain controller can control the angle adjustment motor to adjust the angle of the ESC column according to the adjustment direction based on the target drive duration.

[0081] This embodiment can determine the rolling direction of the target roller in the steering wheel and obtain the number of rolling signal receptions within a preset time. Based on the number of rolling signal receptions, the rolling rate within the preset time is determined. The adjustment type of the target roller is determined to be angle adjustment, and the angle adjustment direction corresponding to the rolling direction under angle adjustment is determined. Based on the preset correspondence between the rolling rate and the target driving time, the target driving time of the corresponding ESC is determined. Finally, based on the target driving time, the angle adjustment motor is controlled to adjust the angle of the ESC according to the adjustment direction.

[0082] The table below (using a preset time of 50ms as an example, and defining the scrolling rate as slow for triggering a signal once within 50ms, medium for triggering a signal 2 to 3 times within 50ms, and fast for triggering a signal 4 or more times within 50ms) shows the following:

[0083] As can be seen, when the user slides the angle adjustment wheel in one direction two or more times quickly, the angle of the ESC column can be continuously adjusted. When the user slides the angle adjustment wheel slowly, the angle of the ESC column can be adjusted with high precision, thus meeting the user's needs and improving the user experience.

[0084] The above embodiment is the second embodiment. The third embodiment is described below, providing yet another method for controlling the ESC (Electronic Speed ​​Regulator) column. The difference between the third and second embodiments is that in the third embodiment, the angle adjustment motor is controlled to adjust the angle of the ESC column according to the target drive duration, following the adjustment direction. This allows for continuous angle adjustment of the ESC column when the user slides the angle adjustment wheel quickly, and high-precision angle adjustment when the user slides the angle adjustment wheel slowly, thus meeting user needs and improving the user experience. In the third embodiment, the length adjustment motor is controlled to adjust the length of the ESC column according to the adjustment direction based on the target drive duration. This also allows for continuous angle adjustment of the ESC column when the user slides the angle adjustment wheel quickly, and high-precision angle adjustment when the user slides the angle adjustment wheel slowly, thus meeting user needs and improving the user experience. Figure 5 As shown: S501. Determine the rolling direction of the target roller in the steering wheel and obtain the number of times the rolling signal is received within a preset time. Determine the rolling rate within the preset time based on the number of times the rolling signal is received.

[0085] Step S501 is similar to step S301 in the second embodiment. For details, please refer to the relevant description in step S301. It will not be repeated here.

[0086] S502. Determine the adjustment type of the target roller as length adjustment and the adjustment direction corresponding to the rolling direction under length adjustment.

[0087] The domain controller can determine that the adjustment type of the target scroll wheel is length adjustment. For example, such as Figure 2A As shown, the adjustment type corresponding to roller B is length adjustment. For example, if a user wants to adjust the length of the steering wheel, they can slide roller B to drive the length adjustment motor to adjust the length of the ESC column, thereby achieving the length adjustment of the steering wheel.

[0088] The domain controller determines the adjustment direction corresponding to the scrolling direction under length adjustment. It should be noted that the length adjustment direction may differ for different scrolling directions.

[0089] For example, if the target roller is a length adjustment roller and the rolling direction is upward, the corresponding adjustment direction can be adjusted to increase the length of the steering wheel. That is, the length adjustment motor can be controlled to adjust the electrically adjustable column along the direction of column extension according to the target drive duration.

[0090] For example, if the target roller is a length adjustment roller and its scrolling direction is downward, the corresponding adjustment direction can be adjusted to shorten the length of the steering wheel. That is, the length adjustment motor can be controlled to adjust the ESC column along the shortening direction of the column according to the target drive duration.

[0091] S503. Based on the preset correspondence between the rolling rate and the driving time, determine the target driving time of the length adjustment motor corresponding to the rolling rate.

[0092] The domain controller can determine the target drive duration of the length motor corresponding to the scrolling rate based on the preset correspondence between the scrolling rate and the drive duration.

[0093] In some possible implementations, the ECU can determine the target regulating current of the ESC column corresponding to the rolling rate based on the preset correspondence between the rolling rate and the drive current.

[0094] After determining the target adjustment current, the target drive duration of the ESC corresponding to the target drive current can be determined according to the preset correspondence between drive current and drive duration. Then, the ESC can be controlled to adjust its length according to the target drive duration and the adjustment direction corresponding to the rolling direction.

[0095] For example, such as Figure 4 As shown, when the user moves roller B, its pulse signal can be transmitted to the domain controller via the CustomSwtSts or enterSwtSts signal lines of the combination switch. The target roller's rolling direction can be transmitted to the domain controller via the VRSwtSts signal line of the combination switch. The domain controller can determine the target drive current of the length adjustment motor corresponding to the rolling rate based on the preset correspondence between the rolling rate and the drive current. Then, based on the preset correspondence between the drive current and the drive duration, it can determine the target drive duration of the ESC corresponding to the target drive current. Finally, it outputs the target drive current to the length adjustment motor. The length adjustment motor can have a built-in Hall signal for real-time closed-loop control to control the ESC to adjust the length in the target drive duration and direction according to the target drive current.

[0096] For example, the correspondence between the scrolling rate and the driving duration can be shown in the table in step S303, which will not be described in detail here. Based on the correspondence between the scrolling rate and the driving duration in the table, the target driving duration of the ESC column corresponding to the scrolling rate can be determined.

[0097] S504. The length adjustment motor is controlled to adjust the length of the ESC column according to the target drive duration, adjustment type, and adjustment direction.

[0098] This embodiment can determine the rolling direction of the target roller in the steering wheel and acquire the number of rolling signal receptions within a preset time. Based on the number of rolling signal receptions, the rolling rate within the preset time is determined. The adjustment type of the target roller is determined to be length adjustment, and the length adjustment direction corresponding to the rolling direction under angle adjustment is determined. Based on the preset correspondence between the rolling rate and the target drive duration, the target drive duration of the corresponding ESC column is determined. Finally, based on the target drive duration, the length adjustment motor is controlled to adjust the length of the ESC column according to the adjustment direction. In this way, when the user slides the angle adjustment roller quickly, the length of the ESC column can be continuously adjusted. When the user slides the angle adjustment roller slowly, the length of the ESC column can be adjusted with high precision, thereby meeting user needs and improving the user experience.

[0099] In some possible implementations, in this embodiment, when the computing device detects that the target rollers include both angle adjustment rollers and length adjustment rollers, it can determine the adjustment direction and rolling rate of each roller. Based on a preset correspondence between rolling rate and drive duration, it determines the target drive duration for each roller. Then, the computing device can control the angle adjustment motor and length adjustment motor to perform a combined adjustment of the angle and length of the electronically controlled transistor according to their respective target drive durations, adjustment types, and adjustment directions. The specific implementation principle is similar to that described in the above embodiments and will not be elaborated further here. By synchronously identifying the rolling rates of the angle adjustment rollers and length adjustment rollers and determining the corresponding target drive durations of the motors, a combined adjustment of rotation and extension can be achieved, thereby improving adjustment efficiency.

[0100] Based on the first embodiment, the second embodiment, or the third embodiment, the technical solution provided in this application can further identify the vehicle's speed during vehicle operation. If the vehicle's speed is determined to be greater than or equal to a threshold speed, then the adjustment of the electronic speed control column is stopped. This embodiment is referred to as the fourth embodiment.

[0101] When the vehicle's speed is determined to be greater than or equal to a threshold speed, the domain controller can immediately lock the ESC column adjustment function, causing the adjustment motor to stop outputting voltage and maintain self-locking. This completely eliminates the risk of column displacement caused by accidental touch, clothing scratches, or passengers playing during high-speed vehicle operation.

[0102] Specifically, once a vehicle's speed exceeds a threshold speed, for example, 30 km / h, the vehicle enters a dynamic stability zone. At this point, any unexpected steering wheel adjustment may amplify the steering wheel yaw rate, potentially leading to lane departure or skidding. Therefore, when the vehicle's speed is determined to be greater than or equal to the threshold speed, the domain controller can immediately lock the ESC column adjustment function and block the roller column adjustment signal. Simultaneously, relevant regulations explicitly prohibit unintended steering movements while driving. Locking the ESC column adjustment function at a low speed below the threshold speed or in a stationary state satisfies these regulations. It should be noted that the threshold speed here is 30 km / h; however, this is just an example, and the threshold speed can be set according to actual needs without further limitations.

[0103] In some possible implementations, a capacitive grip ring can be added for double verification. For example, based on the vehicle speed, the contact area and time between the hand and the steering wheel can be continuously detected. If, based on the contact area between the hand and the steering wheel, the hand is not gripping the steering wheel within a preset time (e.g., within 3 seconds), it can be determined that the driver is in a hands-free state. When the vehicle speed is greater than or equal to a threshold speed and the driver is in a hands-free state, the domain controller can immediately lock the ESC column adjustment function and block the roller column adjustment signal. Even if someone manually moves the roller at this time, it is considered an invalid request, thus completely eliminating accidental adjustments caused by passengers or clothing scratches. Furthermore, prohibiting motor start-stop at high speeds avoids reverse inrush current and worm gear impact wear, keeping the actuator in a power-off self-locking state and extending its lifespan. Other steps are similar to the implementation principles of the first embodiment, the second embodiment, or the third embodiment described above, and can be referred to the relevant descriptions in the above embodiments, which will not be repeated here.

[0104] The difference between this specific implementation and the above-described specific implementation is that it adds the ability to identify the vehicle's speed during vehicle operation and continuously monitor the contact area and time between the driver's hand and the steering wheel. If the vehicle's speed is greater than or equal to a threshold speed and the driver is in a hands-free state, the domain controller can immediately lock the ESC column adjustment function and block the roller column adjustment signal. This strategy, without adding additional hardware, can meet the requirements for prohibiting unintended steering movements through software thresholds, significantly reducing the probability of yaw disturbances, improving driving safety, and reducing the impact of high-speed start-stop on the worm gear, thus extending the life of the actuator.

[0105] Based on the first embodiment, the second embodiment, or the third embodiment, the technical solution provided in this application can also determine the first rolling rate within a preset time when the rolling direction of the target roller changes. According to the preset correspondence between the rolling rate and the driving time, the first target driving time of the regulating motor corresponding to the first rolling rate is determined, and the regulating motor is controlled to adjust the ESC column according to the first target driving time, the adjustment type, and the changed adjustment direction.

[0106] Specifically, the principle of determining the first target drive duration based on the rolling rate and adjusting the ESC column using the first target drive duration is similar to that in the above embodiments, and will not be described in detail here.

[0107] The difference between this specific embodiment and the above-described specific embodiments lies in the addition of a step where, when the rolling direction of the target roller changes, a first rolling rate within a preset time is determined. Based on a preset correspondence between rolling rate and drive duration, a first target drive duration for the regulating motor corresponding to the first rolling rate is determined. The regulating motor is then controlled to adjust the ESC column according to the first target drive duration, adjustment type, and changed adjustment direction. This allows for immediate re-determination of the adjustment speed upon detecting a change in the rolling direction of the target roller, enabling the ESC column to respond immediately to the corresponding adjustment operation, reducing the delay of the ESC column, and further improving the user experience. Other steps are similar in principle to the first embodiment, second embodiment, or third embodiment described above, and will not be elaborated further here. Figure 6 This is a schematic diagram of the structure of a control device for an electrically adjustable column provided in an embodiment of this disclosure.

[0108] In this embodiment, the control device for the electronic control column can be located within an electronic device, and is understood as a functional module within the aforementioned electronic device. Specifically, the electronic device can be a server or a terminal, wherein the terminal specifically includes an in-vehicle terminal, a computer, or a tablet computer, etc., without limitation.

[0109] like Figure 6 As shown, the control device 600 of the electrically controlled column may include: a first determining unit 600, a second determining unit 610, a third determining unit 620, and a control unit 640.

[0110] The first determining unit 600 is used to determine the rolling direction of the target roller in the steering wheel and the rolling rate within a preset time. The rolling rate is used to characterize how fast the target roller rolls. The second determining unit 610 is used to determine the adjustment type of the target roller and the adjustment direction corresponding to the rolling direction under the adjustment type; The third determining unit 620 is used to determine the target driving time of the regulating motor corresponding to the rolling rate according to the preset correspondence between the rolling rate and the driving time. The rolling rate and the driving time of the regulating motor are positively correlated. The control unit 640 is used to control the regulating motor to adjust the ESC column according to the target drive duration, adjustment type and adjustment direction.

[0111] In some possible implementations, the target roller is an angle adjustment roller, and the control unit is specifically used for: When the target roller is rolling upwards, the control angle adjustment motor reduces the angle between the ESC column and the horizontal plane according to the target drive duration; When the target roller is rolling downwards, the control angle adjustment motor increases the angle between the ESC column and the horizontal plane according to the target drive duration.

[0112] In some possible implementations, the target roller length adjustment roller, control unit, is specifically used for: When the target roller rolls upwards, the control length adjustment motor adjusts the ESC column along the extension direction of the ESC column according to the target drive duration; When the target roller is rolling downwards, the control length adjustment motor adjusts the ESC column in the direction of shortening of the ESC column according to the target drive duration.

[0113] In some possible implementations, the first determining unit is specifically used for: The number of scroll signals received within a preset time is obtained, and the target scroll wheel receives one scroll signal when it rolls a preset angle; The scrolling rate is determined based on the number of times the scrolling signal is received, and the number of times the scrolling signal is received is positively correlated with the scrolling rate.

[0114] In some possible implementations, the device further includes: The fourth determining unit is used to determine a first rolling rate within a preset time when the rolling direction of the target roller changes. The fifth determining unit is used to determine the first target driving time of the adjusting motor corresponding to the first rolling rate according to the preset correspondence between the rolling rate and the driving time. The adjustment unit is used to control the adjustment motor to adjust the ESC column according to the first target drive duration, adjustment type, and the changed adjustment direction.

[0115] In some possible implementations, the device further includes: The stop unit is used to obtain the vehicle's driving speed. If the driving speed is greater than or equal to a threshold speed, the adjustment of the ESC column is stopped.

[0116] In some possible implementations, the stopping unit is specifically used for: Continuously monitor the contact area and duration between the palm and the steering wheel; If the hands do not grip the steering wheel within the preset time period determined based on the contact area, then the adjustment of the ESC column will stop.

[0117] In some possible implementations, the control unit is specifically used for: When the target roller is detected to include an angle adjustment roller and a length adjustment roller, the adjustment direction and rolling speed of the angle adjustment roller and the length adjustment roller are determined respectively. Based on the preset relationship between rolling rate and driving time, the target driving time for the angle adjustment roller and the length adjustment roller is determined respectively. The angle adjustment motor and the length adjustment motor are controlled to perform a combined adjustment of the angle and length of the ESC column according to their respective target drive duration, adjustment type and adjustment direction.

[0118] The first determining unit 600 is used to determine the rolling direction of the target roller in the steering wheel and the rolling rate within a preset time, wherein the rolling rate is used to characterize the speed at which the target roller rolls. The second determining unit 610 is used to determine the adjustment type of the target roller and the adjustment direction corresponding to the rolling direction under the adjustment type. The third determining unit 620 is used to determine the target driving time of the adjusting motor corresponding to the rolling rate based on a preset correspondence between the rolling rate and the driving time, wherein the rolling rate and the driving time of the adjusting motor are positively correlated. The control unit 640 is used to adjust the ESC column according to the target drive duration, adjustment type, and adjustment direction based on the control and adjustment motor. Therefore, in this application, the drive duration of the ESC column can be determined based on the frequency at which the user rolls the target roller. Thus, when the user slides the roller quickly, the device provided in this application can increase the drive duration of the ESC column to achieve continuous adjustment of the ESC column; when the user slides the roller slowly, the drive duration of the ESC column can be reduced to achieve precise adjustment of the ESC column at slow speeds, thereby meeting user needs and improving the user experience.
