[0002] With the development of automotive intelligence and electrification, the application requirements for various automotive usage scenarios are increasing. For example, the position and angle of the seats and rearview mirrors, as well as the steering wheel position, can be controlled in conjunction with the electric adjustment column. The electric adjustment column achieves this through a motor and bearings. However, continuous high temperatures after the motor's operation can cause bearing deformation, leading to motor seizure or damage. Therefore, preventing the motor from continuously operating at high temperatures is crucial for ensuring the normal operation of the electric adjustment column, extending its lifespan, and maintaining vehicle safety. Summary of the Invention

[0003] This application provides a control method, device, and storage medium for an electrically adjustable column, which can be used to ensure the normal use of the electrically adjustable column, extend its service life, and maintain vehicle safety. The technical solution is as follows:

[0004] On one hand, embodiments of this application provide a control method for an electrically adjustable column, the method comprising:

[0005] In response to the vehicle key being powered on and all doors being closed, the vehicle's internal linkage control functions are activated.

[0006] The ambient temperature of the vehicle's environment is obtained, and the temperature range corresponding to the ambient temperature is determined. The temperature range includes a first temperature range and a second temperature range, and the temperature in the first temperature range is higher than the temperature in the second temperature range.

[0007] In response to the ambient temperature corresponding to the first temperature range, the number of strokes of the electric adjustment column that completes angle adjustment within a first time period and the number of strokes of extension and retraction adjustment within a second time period are obtained. The electric adjustment column is used to execute the linkage control function.

[0008] In response to at least one of the first number of strokes exceeding a first threshold or the second number of strokes exceeding a second threshold, the linkage control function is controlled to remain off for a third duration.

[0009] On the other hand, a control device for electrically adjusting a tubing column is provided, the device comprising:

[0010] The start module is used to activate the vehicle's internal linkage control functions in response to the vehicle key being powered on and all doors being closed.

[0011] The first acquisition module is used to acquire the ambient temperature of the environment where the vehicle is located, and determine the temperature range corresponding to the ambient temperature. The temperature range includes a first temperature range and a second temperature range, wherein the temperature in the first temperature range is higher than the temperature in the second temperature range.

[0012] The second acquisition module is used to acquire, in response to the temperature range corresponding to the ambient temperature being the first temperature range, the first stroke number of the electric adjustment column completing angle adjustment within a first time period and the second stroke number of the electric adjustment column completing extension and retraction adjustment within a second time period, wherein the electric adjustment column is used to execute the linkage control function.

[0013] A first control module is configured to control the linkage control function to remain closed for a third duration in response to at least one of the first number of strokes exceeding a first threshold or the second number of strokes exceeding a second threshold.

It then acquires the ambient temperature of the vehicle's surroundings and determines the corresponding temperature range. If the ambient temperature falls within the first temperature range, it acquires the first stroke count of the electric adjustment column within a first time period and the second stroke count of the extension / retraction adjustment within a second time period. If at least one of the first stroke count or the second stroke count exceeds a first threshold or a second threshold, the linkage control function remains closed for a third time period. This prevents the electric adjustment column from overheating due to continuous operation, which could cause bearing deformation and affect its normal operation. This extends the lifespan of the electric adjustment column and maintains vehicle safety. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0024] This application provides a control method for an electrically adjustable tubing column. Please refer to [link / reference]. Figure 1 The diagram illustrates the implementation environment of the method provided in this application embodiment. This implementation environment may include: a BCM (Body Control Module) 11, a vehicle key 12, a position sensor 13, a temperature sensor 14, a Hall effect sensor 15, an ECU (Engine Control Unit) 16, and an electric adjustment column 17.

[0025] In one possible implementation, the vehicle key 12 is used to send a power-on signal to the BCM 11 when the key is powered on. A position sensor 13, mounted on the door, is used to acquire the opening and closing status of the doors and send this information to the BCM 11. An electrically adjustable column 17, mounted on the exterior of the vehicle, is used to control the rearview mirrors, seats, and steering wheel to their respective preset positions. A temperature sensor 14, mounted on the exterior of the vehicle, is used to detect the ambient temperature of the vehicle's surroundings and send this information to the BCM 11. The ECU 16 is used to acquire information about whether the engine is stalled, whether the transmission is malfunctioning, whether the tires are stuck, or whether there is an electrical fault, and sends this information to the BCM 11.

[0026] For example, the Hall effect sensor 15 is used to detect the Hall voltage signal. The BCM 11 can determine whether the detected Hall voltage is generated by the angle adjustment of the electric regulating column 17 or by the extension adjustment of the electric regulating column 17 based on the magnitude of the Hall voltage signal. The number of times the two types of Hall voltage signals are generated is counted respectively to determine whether the linkage control function needs to be turned off.

[0027] Among them, BCM11, vehicle key 12, position sensor 13, temperature sensor 14, Hall effect sensor 15, ECU 16 and electric adjustment column 17 establish communication connection through wired or wireless network.

[0028] Based on the above Figure 1 The implementation environment shown in this application provides a control method for an electrically adjustable column, such as... Figure 2 As shown, taking the application of this method to BCM as an example, the method includes steps 201-204.

[0029] In step 201, in response to the vehicle key being powered on and all doors being closed, the BCM activates the vehicle's internal linkage control function.

[0030] In one possible implementation, the BCM can determine whether the key is powered on based on whether it receives a power-on signal from the vehicle key. For example, if the BCM receives a power-on signal from the key, it instructs the vehicle key to power on; if the BCM does not receive a power-on signal from the key, it instructs the vehicle key not to power on. Optionally, the BCM can also obtain the opening and closing status of the doors through position sensors, wherein the position sensors are installed on the doors to detect the opening and closing status of the doors.

[0031] For example, after confirming that the vehicle key is powered on and all doors are closed, the BCM activates the vehicle's internal linkage control functions, including adjusting the rearview mirrors, seats, and steering wheel to their respective preset positions. In one possible implementation, the BCM controls the rearview mirrors, seats, and steering wheel to their respective preset positions via an electrically adjustable column, thus achieving a welcome function.

[0032] Optionally, the preset positions of the rearview mirror, seat, and steering wheel can be pre-set, and different driver and passenger position settings can be memorized. Facial feature data and the position parameters of the rearview mirror, seat, and steering wheel can be stored accordingly. When the corresponding driver or passenger rides again, the facial feature data can be confirmed through the facial recognition function, the position parameters corresponding to the facial feature data can be read, and the rearview mirror, seat, and steering wheel can be adjusted according to the position parameters corresponding to the facial feature data.

[0033] In step 202, the BCM obtains the ambient temperature of the vehicle's environment and determines the temperature range corresponding to the ambient temperature. The temperature range includes a first temperature range and a second temperature range, and the temperature in the first temperature range is higher than the temperature in the second temperature range.

[0034] For example, after the linkage function is activated, the BCM obtains the ambient temperature of the vehicle's surroundings, including: the BCM obtains the ambient temperature of the vehicle's surroundings through a temperature sensor, wherein the temperature sensor is installed outside the vehicle to detect the ambient temperature of the vehicle's surroundings. Optionally, after obtaining the ambient temperature of the vehicle's surroundings, the ambient temperature is compared with a temperature threshold of a first temperature range and a temperature threshold of a second temperature range to determine the temperature range corresponding to the ambient temperature, wherein the temperature range includes a first temperature range and a second temperature range, and the temperature in the first temperature range is higher than the temperature in the second temperature range.

[0035] In one possible implementation, the temperature thresholds for the first and second temperature ranges can be set empirically. For example, the temperature threshold for the first temperature range can be set to 0℃-65℃, and the temperature threshold for the second temperature range can be set to -40℃-0℃.

[0036] In step 203, in response to the temperature range corresponding to the ambient temperature as the first temperature range, the BCM obtains the first stroke number of the electric adjustment column that completes the angle adjustment within the first time period, and the second stroke number of the extension adjustment within the second time period. The electric adjustment column is used to execute the linkage control function.

[0037] Optionally, if the temperature range corresponding to the ambient temperature is determined to be the first temperature range, the BCM obtains the first stroke number of the electric adjustment column completing angle adjustment within the first time period, and the second stroke number of the electric adjustment column completing extension adjustment within the second time period. The electric adjustment column is used to perform the linkage control function, that is, to simultaneously control the rearview mirror, seat and steering wheel of the vehicle to adjust to their respective preset positions.

[0038] For example, the BCM acquires the first number of strokes of the electric adjustment column that completes angle adjustment within a first time period, and the second number of strokes of the electric adjustment column that completes telescopic adjustment within a second time period, including: acquiring the first number of Hall signals generated due to angle adjustment of the electric adjustment column within the first time period, and the second number of Hall signals generated due to telescopic adjustment of the electric adjustment column within the second time period; calculating the first number of strokes of angle adjustment completed within the first time period based on the first number and calculating the second number of strokes of telescopic adjustment completed within the second time period based on the second number.

[0039] In one possible implementation, the BCM uses a Hall effect sensor to acquire the first number of Hall signals generated due to the angle adjustment of the electrically controlled regulating column within a first time period, and the second number of Hall signals generated due to the extension and retraction adjustment of the electrically controlled regulating column within a second time period.

[0040] Optionally, the BCM detects the Hall voltage signal using a Hall effect sensor, and determines whether the detected Hall voltage is generated by the angle adjustment of the electric regulating column or by the extension adjustment of the electric regulating column based on the magnitude of the Hall voltage signal. The number of Hall voltage signals generated by the angle adjustment in the first time period and the number of Hall voltage signals generated by the extension adjustment in the second time period are counted respectively.

[0041] In one possible implementation, based on the number of Hall voltage signals generated by angle adjustment, the first stroke of angle adjustment completed within a first time period is calculated according to the number of Hall voltage signals corresponding to one complete angle adjustment stroke; then, based on the number of Hall voltage signals generated by telescopic adjustment, the second stroke of telescopic adjustment completed within a second time period is calculated according to the number of Hall voltage signals corresponding to one complete telescopic adjustment stroke.

[0042] For example, the first and second durations can be set empirically; for instance, the first duration can be 60 seconds and the second duration can be 120 seconds. The number of Hall voltage signals corresponding to one complete angle adjustment stroke and the number of Hall voltage signals corresponding to one complete telescopic adjustment stroke can be determined in advance through experiments.

[0043] In step 204, in response to at least one of the first number of strokes exceeding the first threshold or the second number of strokes exceeding the second threshold, the BCM control linkage function remains off for a third duration.

[0044] Optionally, after calculating the first and second travel counts, the first travel count is compared with a first threshold, and the second travel count is compared with a second threshold. If at least one of the following conditions is met: the first travel count exceeds the first threshold or the second travel count exceeds the second threshold, the BCM control linkage function remains off for a third duration, i.e., triggering linkage adjustments to the vehicle's rearview mirrors, seats, and steering wheel stops for the third duration. For example, the first threshold, second threshold, and third duration can be set empirically. For instance, the first and second thresholds can be 8, and the third duration can be 60 seconds.

[0045] For example, after the linkage control function remains off for a third period of time, the linkage control function is restored. Optionally, after the linkage control function is off for a third period of time, the BCM linkage control function is restored, that is, the linkage adjustment of the vehicle's rearview mirrors, seats and steering wheel is restored.

[0046] In one possible implementation, the BCM can also determine whether the linkage control function needs to be turned off based on the number of consecutive strokes of angle adjustment or telescopic adjustment. Optionally, the third stroke number and the fourth stroke number of consecutive telescopic adjustment of the electric adjustment column are obtained; in response to the temperature range of the vehicle's environment being a first temperature range, and the third stroke number exceeding a third threshold or the fourth stroke number exceeding a fourth threshold, the linkage control function is kept off for a fourth duration, where the third and fourth thresholds are less than the first and second thresholds; in response to the temperature range of the vehicle's environment being a second temperature range, and the third stroke number exceeding a fifth threshold or the fourth stroke number exceeding a sixth threshold, the linkage control function is kept off for a fifth duration, where the fifth and sixth thresholds are greater than the first and second thresholds.

[0047] Optionally, the BCM counts the number of consecutive angle adjustments completed by the electric adjustment column and the number of consecutive extension adjustments completed by the electric adjustment column based on the voltage signal output by the Hall effect sensor. If the temperature range of the vehicle's environment is the first temperature range, the BCM compares the number of consecutive angle adjustments completed by the third stroke with a third threshold and the number of consecutive extension adjustments completed by the fourth threshold. If the temperature range of the vehicle's environment is the second temperature range, the BCM compares the number of consecutive angle adjustments completed by the third stroke with a fifth threshold and the number of consecutive extension adjustments completed by the fourth threshold. The third and fourth thresholds are less than the first and second thresholds, while the fifth and sixth thresholds are greater than the first and second thresholds.

[0048] For example, if the temperature range of the vehicle's environment is a first temperature range, and at least one of the following conditions is met: the third travel number exceeds a third threshold or the fourth travel number exceeds a fourth threshold, the BCM control linkage function remains off for a fourth duration; if the temperature range of the vehicle's environment is a second temperature range, and at least one of the following conditions is met: the third travel number exceeds a fifth threshold or the fourth travel number exceeds a sixth threshold, the BCM control linkage function remains off for a fifth duration. In one possible implementation, the linkage control function is restored after the required off duration has elapsed.

[0049] Optionally, the third, fourth, fifth, and sixth thresholds, as well as the fourth and fifth durations, can all be set empirically, provided that the third and fourth thresholds are less than the first and second thresholds, and the fifth and sixth thresholds are greater than the first and second thresholds. For example, the third and fourth thresholds can be 5, the fifth and sixth thresholds can be 10, and the fourth and fifth durations can be 60 seconds.

[0050] In one possible implementation, a powertrain stall detection result is acquired, which indicates whether a powertrain malfunction has occurred. In response to the acquisition of a powertrain malfunction detection result, the control linkage function remains closed for a sixth time period. For example, the BCM acquires the powertrain stall detection result by: in response to at least one of engine stall, transmission malfunction, vehicle tire jamming, or electrical fault, the BCM acquires the powertrain malfunction detection result.

[0051] Optionally, the BCM can obtain information from the ECU regarding whether the engine is stalled, whether the transmission is malfunctioning, whether the vehicle's tires are stuck, or whether there is an electrical fault. If at least one of these conditions is met, the BCM obtains a detection result indicating a powertrain fault; if neither the engine nor the transmission is stalled, neither the tires are stuck, and no electrical fault is present, the BCM obtains a detection result indicating no powertrain fault.

[0052] For example, when the engine current exceeds the stall current threshold for more than a seventh time period, the ECU determines that the engine is stalled. In one possible implementation, if a powertrain fault is detected, the BCM control linkage function remains off for the sixth time period. Optionally, the sixth and seventh time periods can be set empirically; for example, the sixth time period can be 60 seconds and the seventh time period can be 1 second.

[0053] In summary, with Figure 3 The control logic diagram of an electrically adjustable column shown is used as an example for illustration. The execution entity can be the BCM (Battery Management Controller). Step 301: The vehicle's linkage control function is activated. Step 302: Determine if a powertrain system malfunctions. If a powertrain system malfunctions, proceed to step 309; if no powertrain system malfunctions, proceed to step 303. Step 303: Obtain the ambient temperature. Step 304: Determine the temperature range corresponding to the ambient temperature. If the ambient temperature corresponds to the first temperature range, proceed to steps 305 and 306; if the ambient temperature corresponds to the second temperature range, proceed to step 307.

[0054] For example, in step 305, determine whether at least one of the following conditions is met: the number of trips exceeds a third threshold or the number of trips exceeds a fourth threshold. If at least one of the following conditions is met, proceed to step 309. In step 306, determine whether at least one of the following conditions is met: the number of trips exceeds a first threshold or the number of trips exceeds a second threshold. If at least one of the following conditions is met, proceed to step 309. In step 307, determine whether at least one of the following conditions is met: the number of trips exceeds a fifth threshold or the number of trips exceeds a sixth threshold. If at least one of the following conditions is met, proceed to step 309. In step 309, disable the linkage control function. In step 310, restore the linkage control function.

[0055] In this embodiment, when the vehicle key is powered on and all doors are closed, the vehicle's internal linkage control function is activated. The ambient temperature of the vehicle's surroundings is acquired, and the corresponding temperature range is determined. If the ambient temperature range is a first temperature range, the number of strokes the electric adjustment column completes for angle adjustment within a first time period and the number of strokes for extension / retraction adjustment within a second time period are acquired. If at least one of the first stroke count exceeding a first threshold or the second stroke count exceeding a second threshold is satisfied, the linkage control function remains closed for a third time period. This prevents the electric adjustment column from continuously operating, which could lead to excessive motor temperature and bearing deformation, thus affecting the normal operation of the electric adjustment column. This extends the lifespan of the electric adjustment column and maintains vehicle safety.

[0056] See Figure 4 This application provides a control device for an electrically adjustable tubing column, the device comprising:

[0057] The start module 401 is used to start the linkage control function inside the vehicle in response to the vehicle key being powered on and all doors being closed.

[0058] The first acquisition module 402 is used to acquire the ambient temperature of the environment where the vehicle is located, and determine the temperature range corresponding to the ambient temperature. The temperature range includes a first temperature range and a second temperature range, and the temperature in the first temperature range is higher than the temperature in the second temperature range.

[0059] The second acquisition module 403 is used to acquire the first stroke number of the electric adjustment column that completes angle adjustment within a first time period and the second stroke number of the electric adjustment column that completes extension and retraction adjustment within a second time period in response to the temperature range corresponding to the ambient temperature as the first temperature range. The electric adjustment column is used to execute the linkage control function.

[0060] The first control module 404 is configured to keep the linkage control function closed for a third duration in response to at least one of the first number of strokes exceeding a first threshold or the second number of strokes exceeding a second threshold.

[0061] In one possible implementation, the start module 401 is used to control the rearview mirrors, seats and steering wheel of the vehicle to adjust to their respective preset positions.

[0062] In one possible implementation, the second acquisition module 403 is used to acquire the first number of Hall signals generated due to the angle adjustment of the electric adjustment column within a first time period, and the second number of Hall signals generated due to the telescopic adjustment of the electric adjustment column within a second time period; calculate the first stroke number of angle adjustment completed within the first time period based on the first number and calculate the second stroke number of telescopic adjustment completed within the second time period based on the second number.

[0063] In one possible implementation, the device further includes: a third acquisition module, configured to acquire a third number of strokes in which the electric adjustment column continuously completes angle adjustment and a fourth number of strokes in which it continuously completes telescopic adjustment; a second control module, configured to, in response to the temperature range of the vehicle's environment being a first temperature range, and the third number of strokes exceeding a third threshold or the fourth number of strokes exceeding a fourth threshold, control the linkage control function to remain closed for a fourth duration, wherein the third threshold and the fourth threshold are less than the first threshold and the second threshold; and a third control module, configured to, in response to the temperature range of the vehicle's environment being a second temperature range, and the third number of strokes exceeding a fifth threshold or the fourth number of strokes exceeding a sixth threshold, control the linkage control function to remain closed for a fifth duration, wherein the fifth threshold and the sixth threshold are greater than the first threshold and the second threshold.

[0064] In one possible implementation, the device further includes: a fourth acquisition module for acquiring the stall detection result of the power system, the stall detection result being used to indicate whether a fault has occurred in the power system; and a fourth control module for controlling the linkage control function to remain closed for a sixth time period in response to acquiring the detection result of a fault in the power system.

[0065] In one possible implementation, the fourth acquisition module is used to acquire a detection result of a powertrain malfunction in response to at least one of the following: engine stall, transmission failure, vehicle tire jamming, or electrical fault.

[0066] In one possible implementation, the first control module 404 is also used to control the restoration of the linkage control function.

[0067] When the vehicle key is powered on and all doors are closed, this device activates the vehicle's internal linkage control function. It then acquires the ambient temperature of the vehicle's surroundings and determines the corresponding temperature range. If the ambient temperature falls within the first temperature range, it acquires the first stroke count of the electric adjustment column within a first time period and the second stroke count of the extension / retraction adjustment within a second time period. If either the first stroke count exceeds a first threshold or the second stroke count exceeds a second threshold, the linkage control function remains off for a third time period. This prevents the electric adjustment column from overheating due to continuous operation, which could deform the bearings and affect its normal operation. This extends the lifespan of the electric adjustment column and maintains vehicle safety.
