[0003] When traveling, items can be placed in the vehicle's trunk. The vehicle can control the movement of the tailgate on the trunk, thereby opening or closing the trunk. The tailgate contains a Hall effect strut, which can drive the tailgate to move. The movement of the tailgate by the Hall effect strut is related to the number of Hall pulses (Hall effect count) from the Hall sensor.

[0004] When the Hall sensor reading is abnormal, the Hall strut stops moving, causing the tailgate to stop moving as well, resulting in the tailgate failing to close. Summary of the Invention

[0005] Based on the above-mentioned technological status, this application provides a vehicle tailgate control method and related equipment to solve the problem of vehicle tailgates failing to close.

Adjust the current movement speed of the tailgate to the movement speed at the target level.

[0007] In some implementations, adjusting the current movement speed of the tailgate to the movement speed at the target level includes: The current position of the tailgate is determined based on its current speed. The duration of movement is determined based on the current position, the closed position of the tailgate, and the speed of movement at the target level. After controlling the tailgate to move at the target speed for the specified duration, the movement stops.

[0008] In some implementations, determining the target level based on the motion level includes: Determine the current position of the tailgate; The target level is determined based on the current location and the level of motion.

[0009] In some implementations, it also includes: Obtain the current movement speed of the tailgate and determine the set Hall effect value associated with the current movement speed of the tailgate; If the difference between the current Hall effect count and the set Hall effect count is greater than a preset difference, the current Hall effect count is determined to be abnormal.

[0010] In some embodiments, after adjusting the current movement speed of the tailgate to the movement speed at the target level, the method further includes: When the tailgate is closed, a tailgate malfunction warning message is output.

[0011] In some implementations, after adjusting the current movement speed of the tailgate to the movement speed at the target level, If the tailgate is detected to be closed, the tailgate is controlled to stop moving.

[0012] Secondly, this application provides a vehicle tailgate control device, comprising: The acquisition module is used to acquire the current Hall number of the Hall sensor in the tailgate during the movement of the tailgate in the vehicle; The determination module is used to determine the current movement level of the tailgate when the current Hall number is abnormal, and to determine a target level based on the movement level, wherein the movement speed at the target level is less than the movement speed at the current movement level; An adjustment module is used to adjust the current movement speed of the tailgate to the movement speed at the target level.

[0013] Thirdly, this application provides a vehicle including a memory and a processor, wherein, The memory is connected to the processor and is used to store programs; The processor is used to implement the vehicle tailgate control method as described in the first aspect or any implementation thereof by running a program in the memory.

[0014] Fourthly, this application provides a computer program product, which, when executed by a processor, implements the vehicle tailgate control method as described in the first aspect or any implementation thereof.

[0015] Fifthly, this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the vehicle tailgate control method as described in the first aspect or any implementation thereof.

[0016] This application provides a vehicle tailgate control method and related equipment. During tailgate movement in the vehicle, the current Hall sensor reading of the tailgate is acquired. If the current Hall sensor reading is abnormal, the current movement speed of the tailgate is determined to be at a specific movement level.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] It should be noted that the user information (including but not limited to electrical equipment information, user personal information, etc.) and data (including but not limited to data used for analysis, data stored, data displayed, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties. Furthermore, the collection, use and processing of the relevant data must comply with relevant laws, regulations and standards, and corresponding operation entry points are provided for users to choose to authorize or refuse.

[0025] As people's living standards improve, vehicles have become an indispensable means of transportation.

[0026] When traveling, items can be placed in the vehicle's trunk. The vehicle can control the movement of the tailgate on the trunk, thereby opening or closing the trunk. The tailgate contains a Hall effect strut, which can drive the tailgate to move. The movement of the tailgate by the Hall effect strut is related to the number of Hall pulses (Hall effect count) from the Hall sensor.

[0027] When the Hall sensor reading is abnormal, the Hall strut stops moving, causing the tailgate to stop moving as well, resulting in the tailgate failing to close.

[0028] In view of this, the embodiments of this application aim to provide a vehicle tailgate control method and related equipment. During the movement of the tailgate in the vehicle, the current Hall value of the Hall sensor in the tailgate is acquired. If the current Hall value is abnormal, the movement level of the current movement speed of the tailgate is determined, a target level lower than the current movement level is determined, and the movement speed at the target level is lower than the current movement speed. Then, the current movement speed of the tailgate is adjusted to the movement speed at the target level. In this application, when the Hall value of the Hall sensor is abnormal, the tailgate movement can be controlled by reducing the movement speed. This ensures that even if there is a performance reduction when the tailgate has a Hall failure, the tailgate function can still be guaranteed to avoid the tailgate failing to close.

[0029] To address the aforementioned technical problems, this application proposes a vehicle tailgate control method, as detailed in the following embodiments.

[0030] Figure 1 A flowchart of a vehicle tailgate control method provided in this application embodiment Figure 1 .like Figure 1 As shown, the vehicle tailgate control method provided in this embodiment includes: Step S101: During the movement of the tailgate in the vehicle, obtain the current Hall value of the Hall sensor in the tailgate.

[0031] In this embodiment, the executing entity is the vehicle tailgate control device. The vehicle tailgate control device can be a control component of the vehicle or the vehicle itself. For ease of description, the term "device" will be used to refer to the vehicle tailgate control device below.

[0032] When the tailgate of the vehicle is in motion, the device acquires the Hall number of the Hall sensor in the tailgate. The Hall number is the Hall pulse number, which is defined as the current Hall number.

[0033] After obtaining the current Hall number, the device determines whether there is an anomaly in the current Hall number.

[0034] In one example, the tailgate's movement speed is related to its current position. For instance, when the tailgate moves downwards, a greater distance between its current position and its closed position requires a higher descent speed; conversely, a smaller distance results in a slower speed to avoid a large impact with the closed position. Conversely, when the tailgate moves upwards, its initial opening requires overcoming gravity and latch resistance, resulting in a slower speed that gradually increases until it approaches its maximum opening position, at which point the speed decreases again. The Hall effect sensor count determines the tailgate's movement speed. Therefore, by detecting the tailgate's current position and direction of movement, the speed can be determined, and the Hall effect sensor count can be derived from this speed. This Hall effect sensor count defines a target count. The device compares the current Hall effect sensor count with the target count. If the difference between the two is greater than a preset difference, a jump in the current Hall effect sensor count is detected, indicating an anomaly.

[0035] In another example, the vehicle is equipped with sensors, and the device detects the current movement speed of the tailgate using these sensors. The movement speed is determined by the ratio between the Hall effect sensor count and the total Hall effect sensor count corresponding to the entire movement of the tailgate. For example, when the ratio is between 0% and 20%, the movement speed is low; if the ratio is between 20% and 80%, the movement speed is medium to high speed and maintains a constant speed; if the ratio is between 80% and 1, the movement speed is low; and around 20% and 80%, the movement speed is a set transition speed. Based on this relationship between movement speed and Hall effect sensor count, the Hall effect sensor count corresponding to the current movement speed can be determined as the set Hall effect sensor count. If the difference between the current Hall effect sensor count and the set Hall effect sensor count is greater than a preset difference, it can be determined that the current Hall effect sensor count is fluctuating, i.e., an abnormal Hall effect sensor count is identified.

[0036] Step S102: In the case of an abnormal Hall number, determine the current movement level of the tailgate and the target level based on the movement level. The movement speed at the target level is less than the movement speed at the current movement level.

[0037] In the event of an abnormal Hall effect reading, determine the current movement speed of the tailgate and its corresponding movement level. Based on this movement level, determine the target movement level, where the movement speed at the target level is lower than the movement speed at the current movement level.

[0038] For example, if the current movement speed is at movement level 3, then level 2 or level 1 can be used as the target level.

[0039] Step S103: Adjust the current movement speed of the tailgate to the movement speed at the target level.

[0040] After determining the target level, adjust the current movement speed of the tailgate to the movement speed required for the target level.

[0041] Furthermore, after the tailgate moves at the target speed, the device can detect whether the tailgate is closed. If it is closed, it outputs a tailgate malfunction warning, prompting the owner to have the tailgate repaired to prevent the tailgate from becoming inaccessible in the future. Additionally, if the tailgate is detected as closed, the device stops its movement to prevent the tailgate motor from stalling for too long and burning out.

[0042] In this embodiment, during the tailgate's movement within the vehicle, the current Hall sensor reading of the tailgate is acquired. If the current Hall sensor reading is abnormal, the current movement speed of the tailgate is determined to be at a specific movement level. A target movement level is identified, which is lower than the current movement speed. The movement speed at the target level is lower than the current movement speed. The current movement speed of the tailgate is then adjusted to the target level. In this embodiment, when the Hall sensor reading is abnormal, a reduced movement speed can be used to control the tailgate's movement. This ensures that even with a performance reduction due to a Hall sensor malfunction, the tailgate's functionality is still maintained, preventing it from failing to close.

[0043] Figure 2 A flowchart of a vehicle tailgate control method provided in this application embodiment Figure 2 ,based on Figure 1 In the embodiment shown, step S103 includes: Step S201: Determine the current position of the tailgate based on its current speed.

[0044] In this embodiment, the tailgate can operate at the reduced speed, but due to a malfunction in the Hall sensor, the accuracy of tailgate movement control will decrease. To avoid a large collision with the closing position when the tailgate closes, the device can determine the tailgate's movement duration. To this end, the device determines the tailgate's current position based on its current speed. The determination of the tailgate's current position based on the current speed is detailed in the above embodiment and will not be repeated here.

[0045] Step S202: Determine the movement duration based on the current position, the closing position of the tailgate, and the movement speed at the target level.

[0046] After determining the current position, the duration of movement can be determined based on the current position, the closed position, and the speed of movement. For example, the tailgate has a plane at the current position and another plane at the closed position; the angle between these two planes is the angle the tailgate needs to rotate, defined as the target angle. The speed of movement at the target level can be converted into angular velocity, and the ratio of the target angle to the angular velocity is the duration of movement.

[0047] Step S203: Control the tailgate to move at the target speed for the specified duration, and then stop moving.

[0048] After determining the duration of movement, the device controls the tailgate to move at the target speed for the specified duration, and then stops moving.

[0049] In this embodiment, the current position of the tailgate is determined based on its current movement speed. The movement duration is determined based on the current position, the closed position of the tailgate, and the movement speed at the target level. This controls the tailgate to move at the movement speed at the target level for the specified duration before stopping, thus preventing excessive collisions between the tailgate and the closed position.

[0050] Figure 3 A flowchart of a vehicle tailgate control method provided in this application embodiment Figure 3 ,based on Figure 1 In the embodiment shown in Or 2, step S102 includes: Step S301: Determine the current position of the tailgate.

[0051] In this embodiment, the device determines the current position of the tailgate. In one example, the device can detect the current position of the tailgate using a position sensor. In another example, the device can determine the current position using the current speed of movement, as described above, and will not be repeated here.

[0052] Step S302: Determine the target level based on the current location and the level of motion.

[0053] After determining the current location, the target level is determined based on the current location and the level of motion.

[0054] For example, the device determines the distance between the current position and the closed position. If the distance is greater than a preset distance, the target level can be set higher. For example, if the motion level is 3, the target level can be 2 instead of 1. If the distance is less than or equal to the preset distance, the target level can be set lower. For example, if the motion level is 3, the target level can be 1 instead of 2.

[0055] In this embodiment, the target level is reasonably set based on the current position and movement level of the tailgate.

The movement speed at the target level is less than the movement speed at the current movement level.

[0057] In some implementations, the vehicle tailgate control device 400 is also used for: Determine the current position of the tailgate based on its current speed.
