Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more specifically, to a method and device for controlling a vehicle tailgate and a vehicle in the field of vehicle technology. Background Art

[0002] With the advancement of technology in the automotive field and the increasing demand for operational comfort, the tailgates of many cars have been upgraded to electric tailgates. Users send instructions to the tailgate controller by operating the remote control switch or the electric tailgate operation switch. After receiving the instructions, the tailgate controller automatically controls the tailgate to open or close through the motor.

[0003] Currently, self-priming locks are mainly used in electric tailgates of vehicles. Since there is no limit on the number of self-priming locks, how to prevent motor burnout when the vehicle tailgate executes the locking command has become a problem that needs to be solved urgently. Summary of the Invention

[0004] The present application provides a vehicle tailgate control method, device and vehicle, which can promptly control the target tailgate (upper tailgate and / or lower tailgate) to stop performing the locking action when a self-priming obstacle occurs in the target tailgate, thereby avoiding motor ablation caused by continuous operation of the motor.

[0005] In a first aspect, a method for controlling a vehicle tailgate is provided, wherein the vehicle tailgate includes an upper tailgate and a lower tailgate, and the upper tailgate and the lower tailgate are arranged to open vertically. The method comprises:

[0006] When receiving a locking instruction of a target tailgate, controlling the target tailgate to perform a locking action; the target tailgate includes an upper tailgate and / or a lower tailgate;

[0007] When the target tailgate is in a half-locked state during the locking operation, detecting whether the target tailgate is in a fully locked state within a target preset time period;

[0008] If the target tailgate is not in the fully locked state within the target preset time, the target tailgate is controlled to stop performing the locking action.

[0009] In the above technical solution, when the target tailgate is in a semi-locked state during the execution of the locking action, it is detected whether the target tailgate is in a fully locked state within the target preset time length; because the door lock in the tailgate generally starts to self-prime after changing from an unlocked state to a semi-locked state; therefore, if the target tailgate is not in a fully locked state within the target preset time length, the target tailgate is controlled to stop executing the locking action. When the target tailgate has a self-priming obstacle, the target tailgate can be controlled to stop executing the locking action in time (for example, the motor is controlled to stop running) to avoid electrode ablation caused by continuous operation of the motor.

[0010] In conjunction with the first aspect, in certain possible implementations, if the target tailgate is not in the fully locked state within the target preset time period, controlling the target tailgate to stop performing the locking action includes:

[0011] If the target tailgate is not in the fully locked state within the target preset time, the target tailgate is detected to see if there is an obstacle in the door lock; if there is no obstacle in the door lock of the target tailgate, the target tailgate is controlled to stop performing the locking action.

[0012] In the above technical solution, if the target tailgate is not in the fully locked state within the target preset time period, the target tailgate cannot be in the fully locked state due to the presence of an obstacle in the door lock or a malfunction of the door lock itself. Therefore, the door lock of the target tailgate is subjected to obstacle detection, and the target tailgate is controlled to perform the locking action when there is no obstacle in the door lock; when the door lock itself malfunctions, the locking action can be stopped in time to avoid motor burnout.

[0013] In combination with the first aspect and the above implementations, in certain possible implementations, the upper tailgate includes a first door lock and a second door lock, and the lower tailgate includes a third door lock and a fourth door lock. If the target tailgate is not in a fully locked state within a target preset time period, controlling the target tailgate to stop performing the locking action includes:

[0014] If the target tailgate is not in a fully locked state within the target preset time length, it is determined that there is a target door lock with a self-priming obstacle, and the target door lock includes at least one door lock among the first door lock, the second door lock, the third door lock and the fourth door lock; the target door lock is controlled to stop performing the locking action.

[0015] In the above technical solution, when there are multiple door locks in the upper tailgate and the lower tailgate, the target door lock with self-priming obstacle is determined, and the door lock with self-priming obstacle can be accurately located; the target door lock is controlled to stop performing the locking action, and when some of the door locks of the multiple door locks fail, only the door lock with self-priming failure is controlled to stop performing the locking action, so that the door locks with normal self-priming can smoothly reach the full locking state without affecting the normal closing of the tailgate.

[0016] In combination with the first aspect and the above implementations, in some possible implementations, the present invention further includes:

[0017] Determine the number of target door locks; if the number is greater than a preset threshold, control the vehicle to issue an alarm in a preset manner; the alarm is used to indicate that the target door lock has a self-priming obstacle.

[0018] In the above technical solution, if the number of door locks with self-priming failure is greater than the preset threshold, it means that it may affect the normal closing of the vehicle's tailgate and there is a major safety hazard; therefore, controlling the vehicle to alarm in a preset manner can promptly remind the user that the target door lock has a self-priming obstacle so that the user can perform maintenance in time.

[0019] In combination with the first aspect and the above implementations, in some possible implementations, the present invention further includes:

[0020] Detect whether there is an obstacle in the target door lock; if there is an obstacle in the target door lock, send a first prompt message, the first prompt message is used to prompt the user that there is an obstacle in the target door lock; if there is no obstacle in the target door lock, send a second prompt message, the second prompt message is used to prompt the user that there is a fault in the target door lock.

[0021] In the above technical solution, obstacle detection is performed on the target door lock (i.e., the door lock with self-priming obstacle); when there is an obstacle, the user is prompted that there is an obstacle in the target door lock; when there is no obstacle, the user is prompted that there is a fault in the target door lock; this allows the user to promptly understand the specific cause of the self-priming obstacle, avoids manual detection of the cause of the tailgate fault, and improves the user experience.

[0022] In combination with the first aspect and the above implementations, in certain possible implementations, the upper tailgate is provided with an outer ledge, and the lower tailgate is provided with an inner ledge; when both the upper tailgate and the lower tailgate are currently locked, the outer ledge covers the inner ledge, and when a locking command for a target tailgate is received, controlling the target tailgate to perform a locking action includes:

[0023] When the locking instructions of the upper tailgate and the lower tailgate are received, the lower tailgate is controlled to perform the locking action; when it is detected that the lower tailgate is in the fully locked state, the upper tailgate is controlled to perform the locking action.

[0024] In the above technical solution, since the outer edge of the upper tailgate covers the outer edge of the lower tailgate in the locked state, based on this structure, when the locking instructions of the upper tailgate and the lower tailgate are received, the lower tailgate is first controlled to perform the locking action. When the lower tailgate is in the fully locked state, the upper tailgate is controlled to perform the locking action, which can ensure that both the upper tailgate and the lower tailgate can be successfully closed and locked.

[0025] In combination with the first aspect and the above implementations, in some possible implementations, the present invention further includes:

[0026] Control the target tailgate to unlock and open to the preset position.

[0027] In the above technical solution, since the user or maintenance personnel generally needs to open the tailgate to check the fault after the door lock has a self-priming fault, the target tailgate is controlled to perform the unlocking action and the target tailgate is controlled to open to the preset position, reducing the operation of the user or maintenance personnel manually initiating the unlocking command or manually opening the tailgate, thereby improving the user experience.

[0028] In combination with the first aspect and the above implementations, in some possible implementations, upon receiving a locking instruction for a target tailgate, controlling the target tailgate to perform a locking action includes:

[0029] If the vehicle is in the target state, upon receiving the locking command of the target tailgate, the target tailgate and vehicle doors are controlled to perform the locking action, and the windows, sunroof and lights in the vehicle are controlled to be in the closed state; among which, the target state includes the vehicle key not being detected, the engine being off, the vehicle doors being closed and the lower tailgate being closed.

[0030] In the above technical solution, since the vehicle is in the target state (for example, the vehicle key is not detected, the engine is off, and the doors are closed), receiving the locking command of the target tailgate indicates that the user may be about to leave the vehicle; therefore, controlling the target tailgate and doors to perform the locking action, and controlling the windows, sunroof and lights in the vehicle to be in the closed state can avoid the risk of the owner forgetting to lock the car after closing the tailgate, thereby improving the human-vehicle interaction experience.

[0031] In a second aspect, a vehicle tailgate control device is provided, the device comprising:

[0034] The second control module is configured to control the target tailgate to stop performing the locking action if the target tailgate is not in the fully locked state within a target preset time period.

[0035] In combination with the second aspect, in some possible implementations, the second control module is specifically used to detect whether there is an obstacle in the door lock of the target tailgate if the target tailgate is not in a fully locked state within a target preset time length; if there is no obstacle in the door lock of the target tailgate, control the target tailgate to stop performing the locking action.

[0036] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the upper tailgate includes a first door lock and a second door lock, and the lower tailgate includes a third door lock and a fourth door lock. The second control module is also used to determine the target door lock with self-priming obstacle if the target tailgate is not in a fully locked state within the target preset time length, and the target door lock includes at least one of the first door lock, the second door lock, the third door lock and the fourth door lock; and control the target door lock to stop performing the locking action.

[0037] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes a first determination module for determining the number of target door locks; a third control module for controlling the vehicle to issue an alarm prompt in a preset manner; the alarm prompt is used to indicate that there is a self-priming obstacle in the target door lock.

[0038] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the device also includes a second detection module for detecting whether there is an obstacle in the target door lock; a first sending module for sending a first prompt message if there is an obstacle in the target door lock, and the first prompt message is used to prompt the user that there is an obstacle in the target door lock; a second sending module for sending a second prompt message if there is no obstacle in the target door lock, and the second prompt message is used to prompt the user that there is a fault in the target door lock.

[0039] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the upper tailgate is provided with an outer lap edge, and the lower tailgate is provided with an inner lap edge; when the current states of the upper tailgate and the lower tailgate are both locked, the outer lap edge covers the inner lap edge; the first control module is specifically used to control the lower tailgate to perform a locking action when receiving a locking instruction from the upper tailgate and the lower tailgate; and control the upper tailgate to perform a locking action when it is detected that the lower tailgate is in a fully locked state.

[0040] In combination with the second aspect and the above implementations, in some possible implementations, the device further includes a fourth control module, configured to control the target tailgate to perform an unlocking action and control the target tailgate to open to a preset position.

[0041] In combination with the second aspect and the above-mentioned implementation methods, in some possible implementation methods, the first control module is also used to control the target tailgate and the vehicle doors to perform a locking action when the vehicle is in a target state and receives a locking command for the target tailgate, and to control the windows, sunroof and lights in the vehicle to be in a closed state; wherein the target state includes the vehicle key not being detected, the engine being off, the vehicle door being closed and the lower tailgate being closed.

[0042] In a third aspect, a vehicle is provided, comprising a memory and a processor.

[0059] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0060] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0061] Figure 1 It is a structural schematic diagram of a vehicle tailgate provided in an embodiment of the present application.

[0062] For example, Figure 1 As shown, the tailgate of the vehicle 100 is composed of an upper tailgate 10 and a lower tailgate 20 , and the upper tailgate 10 and the lower tailgate 20 are in a vertically opening type.

[0063] Optionally, the upper tailgate 10 and the lower tailgate 20 may be controlled independently or in linkage. It should be understood that the independent control and linkage control of the upper tailgate and the lower tailgate will be described in detail later.

[0064] For example, when receiving a locking command for the upper tailgate 10 or the lower tailgate 20, the tailgate controller controls the upper tailgate 10 or the lower tailgate 20 to perform a locking action. During the locking process, the upper tailgate 10 or the lower tailgate 20 is first controlled from an unlocked state to a semi-locked state. When the upper tailgate 10 or the lower tailgate 20 is in a semi-locked state, a semi-locked signal is triggered. When the tailgate controller detects the semi-locked signal, it energizes the self-priming motor, performs a self-priming action, and self-primes the upper tailgate 10 or the lower tailgate 20 to a fully locked position. When the fully locked position is reached, a fully locked signal is triggered.

[0065] During the self-priming process, since the self-priming lock has no limit on the number of self-priming times, when a self-priming obstacle occurs, the self-priming motor will continue to perform the self-priming action, causing the self-priming motor to be easily burned.

[0066] In response to the above technical problems, an embodiment of the present application provides a vehicle tailgate control method, device and vehicle. The method can promptly control the target tailgate to stop performing the locking action when a self-priming obstacle occurs in the target tailgate, thereby avoiding motor ablation caused by continuous operation of the motor.

[0067] The following combination Figures 2 to 13 The vehicle tailgate control method provided in the embodiment of the present application is described in detail.

[0068] Figure 2 1 is a schematic flow chart of a vehicle tailgate control method provided by an embodiment of the present application. The execution subject of the method can be a computing device with computing and processing functions in the vehicle 100, such as a body domain controller.

[0069] For example, Figure 2 As shown, the method 200 includes S210 to S230, and S210 to S230 are described in detail below.

[0070] S210 , when a locking instruction of a target tailgate is received, the target tailgate is controlled to perform a locking action.

[0071] The target tailgate may be an upper tailgate or a lower tailgate, or may be both an upper tailgate and a lower tailgate.

[0072] In some embodiments, the locking instruction of the target tailgate may be received in any of the following ways.

[0073] Implementation method 1: Receive the user's voice command and obtain the locking instruction of the target tailgate based on the voice command.

[0074] For example, when the vehicle is powered on and the vehicle speed is less than a preset threshold (for example, 5 km / h), after the vehicle voice function is activated and the user issues a voice command of "close the upper or lower tailgate or the upper tailgate or the lower tailgate", the voice module transmits the closing request to the body domain controller, and the body domain controller sends a locking command to the tailgate controller.

[0075] Implementation method 2: receiving a first touch operation of the user on the central control screen of the vehicle, and obtaining a locking instruction of the target tailgate based on the first touch operation.

[0076] For example, when the vehicle is powered on, the vehicle speed is less than or equal to 5 km / h, and the vehicle central control screen is activated, the user clicks on the display icon of the upper tailgate or lower tailgate or the upper and lower tailgates on the vehicle central control screen, the host module transmits the locking command to the body domain controller, and the body domain controller sends the locking command to the tailgate controller.

[0077] Implementation method 3: receiving a control signal from a vehicle key, and obtaining a locking instruction for a target tailgate based on the control signal.

[0078] For example, when the vehicle is powered on, the vehicle speed is less than or equal to 5 km / h, and the vehicle key is within a first predetermined range (30 m) of the vehicle, the tailgate control button on the key is pressed, and the high-frequency receiving module sends a locking command to the body domain controller, and the body domain controller sends a locking command to the tailgate controller.

[0079] Implementation method 4: receiving an operation instruction issued by the user through a terminal device connected to the vehicle, and obtaining a locking instruction for the target tailgate based on the operation instruction.

[0080] For example, when the vehicle is powered on and the vehicle speed is less than or equal to 5 km / h, the user operates an application (APP) connected to the vehicle and initiates a locking command for the upper tailgate or the lower tailgate or both tailgates in the APP. The vehicle's telematics box (TBOX) module sends the locking command to the body domain controller, and the body domain controller sends the locking command for the target tailgate to the tailgate controller.

[0081] In another method, the user initiates a locking command for the target tailgate via Bluetooth. The vehicle's Bluetooth low energy (BLE) module receives the control request and, after determination by the vehicle body domain controller, sends the locking command for the target tailgate to the tailgate controller.

[0082] Implementation method 5: receiving a second touch operation of the user on a micro switch provided on the vehicle, and obtaining a locking instruction of the target tailgate based on the second touch operation.

[0083] To facilitate users to open the tailgate from outside the vehicle, micro switches can be set on the upper tailgate and the lower tailgate respectively. Users can initiate the tailgate locking command by touching or pressing the micro switch.

[0084] It should be understood that the above method is only an example, and the present application does not specifically limit the method of receiving the locking instruction of the target tailgate.

[0085] Furthermore, the target tailgate is controlled to perform a locking action.

[0086] It should be understood that the opening and closing control strategies of the upper and lower tailgates of different structures are also different. Below, the opening and closing control strategies of the upper and lower tailgates of different structures are described in detail.

[0087] Figure 3 A schematic structural diagram of another tailgate provided in an embodiment of the present application.

[0088] For example, Figure 3As shown, the upper tailgate 10 is provided with an outer lap edge, and the lower tailgate 20 is provided with an inner lap edge. When the upper tailgate 10 and the lower tailgate 20 are in a locked state, the outer lap edge of the upper tailgate 10 covers the inner lap edge of the lower tailgate 20.

[0089] See also Figure 3 As shown in FIG. 1 , when the upper tailgate 10 and the lower tailgate 20 are in the locked state, if an unlocking command for the upper tailgate 10 and the lower tailgate 20 is received, the upper tailgate 10 needs to be unlocked and opened first, and then the lower tailgate 20 needs to be unlocked and opened; see FIG. Figure 3 As shown in Figure (b), when the upper tailgate 10 and the lower tailgate 20 are in the open state, if a locking command for the upper tailgate and the lower tailgate is received, it is necessary to first control the lower tailgate 20 to perform the locking action. After the lower tailgate 20 is successfully locked, the upper tailgate 10 is controlled to perform the locking action.

[0090] Optionally, the upper tailgate may be controlled to open to the fully open position before the lower tailgate is controlled to open; the lower tailgate may be controlled to close to the fully closed position before the upper tailgate is controlled to close; or, the upper tailgate may be controlled to open to a preset angle before the lower tailgate is controlled to open, and the lower tailgate may be controlled to close to a preset angle before the upper tailgate is controlled to close.

[0091] For example, Figure 4 Schematic diagram of the opening and closing process of a vehicle tailgate provided in an embodiment of the present application. Figure 4 As shown, both the upper tailgate and the lower tailgate are in a closed state. When the body domain controller 401 receives any electric opening instruction, it sends the opening instruction to the upper tailgate controller 402 and the lower tailgate controller 403. The upper tailgate controller 402 determines and executes to open the upper tailgate. When the upper tailgate is fully opened, the lower tailgate controller 403 controls to open the lower tailgate. Optionally, both the upper tailgate and the lower tailgate are in an open state. When the body domain controller 401 receives any electric closing instruction, it sends the closing instruction to the upper tailgate controller 402 and the lower tailgate controller 403. When the lower tailgate controller 403 controls the lower tailgate to be fully closed, the upper tailgate controller 402 detects the lower tailgate locking signal and then controls the upper tailgate to close.

[0092] Therefore, based on the above Figure 3 In the tailgate structure, the implementation process of S210 may be: when a locking instruction of the upper tailgate and the lower tailgate is received, the lower tailgate is controlled to perform a locking action; when it is detected that the lower tailgate is in a fully locked state, the upper tailgate is controlled to perform a locking action.

[0093] For example, when both the upper tailgate and the lower tailgate are in the open state, when the locking command of the upper tailgate and the lower tailgate is received, the lower tailgate is controlled to perform the locking action first, and when the full lock signal of the lower tailgate is received, the upper tailgate is controlled to perform the locking action.

[0094] In the above technical solution, since the outer edge of the upper tailgate covers the outer edge of the lower tailgate in the locked state, based on this structure, when the locking instructions of the upper tailgate and the lower tailgate are received, the lower tailgate is first controlled to perform the locking action. When the lower tailgate is in the fully locked state, the upper tailgate is controlled to perform the locking action, which can ensure that both the upper tailgate and the lower tailgate can be successfully closed and locked.

[0095] Figure 5 This is a schematic structural diagram of another tailgate provided in an embodiment of the present application.

[0096] For example, Figure 5 As shown, the opening or closing of the upper tailgate 10 and the lower tailgate 20 will not affect each other.

[0097] See also Figure 5 As shown in FIG. 1 , when the upper tailgate 10 and the lower tailgate 20 are in a locked state, if an unlock command for the upper tailgate and the lower tailgate is received, the upper tailgate 10 and the lower tailgate 20 can be controlled to be unlocked and opened simultaneously; if an unlock command for the upper tailgate or the lower tailgate is received, only the corresponding upper tailgate or the lower tailgate can be controlled to be unlocked and opened; see FIG. Figure 5 As shown in Figure (b), when the upper tailgate 10 and the lower tailgate 20 are in the unlocked state, if a locking command for the upper tailgate and the lower tailgate is received, the upper tailgate 10 and the lower tailgate 20 can be controlled to be locked at the same time; if an unlocking command for the upper tailgate or the lower tailgate is received, only the corresponding upper tailgate or the lower tailgate can be controlled to be unlocked and opened.

[0098] For example, Figure 6 This is another schematic diagram of the opening and closing process of a vehicle tailgate provided by an embodiment of the present application. Figure 6 As shown, when the body domain controller 601 receives an electric opening or closing instruction for any tailgate, it sends the instruction to the tailgate controller 602, and the tailgate controller 602 controls the upper tailgate and the lower tailgate to open at the same time, or the upper tailgate or the lower tailgate to close at the same time.

[0099] Based on the above Figure 5 In the tailgate structure, the implementation process of S210 may be: when a locking instruction of the upper tailgate and the lower tailgate is received, the upper tailgate and the lower tailgate are controlled to perform a locking action simultaneously.

[0100] In some embodiments, to ensure that items in the trunk will not scratch the target tailgate when it is locked, the length of the items in the trunk can also be identified before controlling the target tailgate to perform the locking action. If it is determined based on the length of the items that there is a risk of scratching the target tailgate, an alarm prompt will be issued.

[0101] Exemplarily, an image acquisition device (e.g., a camera) is installed on the inside of the target tailgate. When a locking command of the target tailgate is received, the image acquisition device in the target tailgate is controlled to capture images of items in the trunk. Based on the images of the items, it is determined whether the length of the items is greater than the width of the trunk. If so, a voice prompt may be given, and the content of the voice prompt may be "Please note that the items in the trunk are too long and may scratch the tailgate. It is recommended to replace them!"

[0102] Another possible implementation method is that if it is recognized that part of the structure of the object protrudes from the trunk, it is determined that the object has the risk of scratching the target tailgate. At this time, a voice prompt can be given, and the content of the prompt can be "Please note that the item in the trunk protrudes from the trunk and may scratch the tailgate. It is recommended to replace it!"

[0103] In some embodiments, in order to avoid the risk of overloading the tailgate lock due to items in the trunk during the locking process of the target tailgate, before controlling the target tailgate to perform the locking action, the volume of the items in the trunk or the placement of the items can also be identified. If the tailgate lock is determined to be at risk of overloading based on the volume of the items or the placement of the items, an alarm prompt will be issued.

[0104] Exemplarily, when a locking instruction of a target tailgate is received, the image acquisition device in the target tailgate is controlled to capture an image of the items in the trunk, and whether the volume of the items is larger than the volume of the trunk is determined based on the image of the items; or, whether the items are placed close to the trunk door opening (for example, the distance from the edge of the trunk door opening is less than a preset threshold) is determined based on the image of the items. If the volume of the items is larger than the volume of the trunk, it is determined that the tailgate door lock is at risk of overloading, and a voice prompt may be given at this time, and the prompt content may be "Please note that there are too many items in the trunk, and the door lock is at risk of overloading. It is recommended to reduce the volume of the items"; if the items are placed close to the trunk door opening, it is determined that the tailgate door lock is at risk of overloading, and a voice prompt may be given at this time, and the prompt content may be "Please note that there are too many items in the trunk, and the door lock is at risk of overloading. It is recommended to adjust the placement of the items."

[0105] Furthermore, if the user processes the object based on the prompt information and determines from the object image that there is no risk of the object scratching the target tailgate or the target tailgate lock being overloaded, the target tailgate is controlled to perform a locking action.

[0106] In the above technical solution, before controlling the target tailgate to perform the locking action, the status of the items in the trunk is identified. When there is a risk of scratching the tailgate or the risk of overloading the door lock, an alarm is issued in time, so that the user can notice the abnormality in time and avoid forced locking to damage the tailgate or door lock.

[0107] S220 , when the target tailgate is in a half-locked state during the locking operation, detecting whether the target tailgate is in a fully locked state within a target preset time period.

[0108] The target preset time length can be set by a person skilled in the art, and the embodiment of the present application does not specifically limit this. For example, the target preset time length is 4 seconds.

[0109] For example, when the target tailgate is in a half-locked state, the tailgate controller will receive a half-lock signal and start timing. If no full-lock signal is received within the target preset time (for example, 4 seconds), it is determined that the target tailgate is not in a full-locked state within the preset time.

[0110] S230: If the target tailgate is not in the fully locked state within the target preset time period, the target tailgate is controlled to stop performing the locking action.

[0111] It should be understood that if the target tailgate is not in a fully locked state within the target preset time, it means that the target tailgate has a self-priming fault. In order to avoid motor ablation caused by continuous self-priming, the power supply to the motor can be stopped at this time to stop the motor from working, that is, to control the target tailgate to stop locking.

[0112] In some embodiments, there are generally two reasons why the target tailgate has a self-priming failure: 1. There is an obstacle (eg, mud, etc.) in the door lock; 2. The door lock itself has a failure.

[0113] Therefore, in order to further determine the cause of the self-priming failure, the implementation process of S230 can be: if the target tailgate is not in a fully locked state within the target preset time length, detect whether there is an obstacle in the door lock of the target tailgate; if there is no obstacle in the target door lock, control the target tailgate to stop performing the locking action.

[0114] Optionally, a camera or other sensor can be installed at the door lock to detect whether there is an obstacle in the door lock. If there is no obstacle, it means that the door lock itself has a fault. At this time, the target tailgate is controlled to stop locking to avoid damage to the motor.

[0115] In the above embodiment, if the target tailgate is not in the fully locked state within the target preset time period, the target tailgate cannot be in the fully locked state due to the presence of an obstacle in the door lock and a malfunction of the door lock itself. Therefore, the door lock of the target tailgate is subjected to obstacle detection, and the target tailgate is controlled to perform the locking action when there is no obstacle in the door lock; when the door lock itself malfunctions, the locking action can be stopped in time to avoid motor burnout.

[0116] It should be understood that if there are multiple door locks on the target tailgate, if the target tailgate has a self-priming failure, there will be two situations: some door locks have a self-priming failure and all door locks have a self-priming failure. Therefore, the door locks with self-priming failure can be controlled to stop locking action in a targeted manner.

[0117] Figure 7 This is a schematic diagram of a door lock provided in an embodiment of the present application.

[0118] For example, Figure 7 As shown, the upper tailgate includes a first door lock 71 and a second door lock 72, and the lower tailgate includes a third door lock 73 and a fourth door lock 74. It should be understood that Figure 7 The positions and numbers of the door locks shown in the figure are merely examples and are not specifically limited in the embodiments of the present application.

[0119] In the case where there are multiple door locks as mentioned above, the implementation process of S230 may be: if the target tailgate is not in a fully locked state within a preset target time, determining a target door lock with a self-priming obstacle; and controlling the target door lock to stop performing the locking action.

[0120] It should be understood that when all door locks in the target tailgate are in the fully locked state, it can be understood that the target tailgate is in the fully locked state, and when some door locks in the target tailgate are not in the fully locked state, it can be understood that the target tailgate is not in the fully locked state.

[0121] Optionally, the target door lock with self-priming obstacle can be determined based on the full lock signal of the door lock. For example, when the target tailgate is the upper tailgate, in the process of controlling the target tailgate to perform the locking action, the first door lock is in the semi-locked state and feeds back a full lock signal to the door controller within the target preset time, and the second door lock does not feed back a full lock signal, then the target door lock is determined to be the second door lock.

[0122] Furthermore, since the first door lock is self-priming normally, only the second door lock can be controlled to stop performing the locking action.

[0123] In the above technical solution, when there are multiple door locks in the upper tailgate and the lower tailgate, the target door lock with self-priming obstacle is determined, and the door lock with self-priming obstacle can be accurately located; the target door lock is controlled to stop performing the locking action, and when some of the door locks of the multiple door locks fail, only the door lock with self-priming failure is controlled to stop performing the locking action, so that the door lock with normal self-priming can smoothly reach the full locking state without affecting the normal closing of the tailgate.

[0124] Figure 8 It is a schematic flow chart of another vehicle tailgate control method provided in an embodiment of the present application.

[0125] For example, Figure 8As shown, the method 800 includes S810 to S860, and S810 to S860 are described in detail below.

[0126] S810: When a locking instruction of a target tailgate is received, the target tailgate is controlled to perform a locking action.

[0127] For example, the implementation of S810 may refer to the relevant description of the S210 process in the above exemplary embodiment, which will not be repeated here.

[0128] In some embodiments, to prevent the user from forgetting to lock the vehicle after closing the tailgate, the implementation process of S810 may be: if the vehicle is in the target state, upon receiving the locking command of the target tailgate, the target tailgate and vehicle doors are controlled to perform the locking action, and the windows, sunroof and lights in the vehicle are controlled to be in the closed state.

[0129] The target state may be that the vehicle key is not detected, the engine is off, and the door is closed.

[0130] It should be understood that different settings can be made for the target state of the vehicle according to different types of tailgate structures. Figure 9 and Figure 10 This process is described.

[0131] Figure 9 This is a schematic flow chart of vehicle locking provided in an embodiment of the present application.

[0132] For example, Figure 9 As shown, when the tailgate structure in the vehicle is Figure 4 In the structure shown in , when the vehicle is turned off, the four door locks are closed, and the key is not in the vehicle, if the user touches the vehicle tailgate lock switch, the corresponding vehicle executes the vehicle locking instruction, and the four door locks are controlled by the body domain control unit 901, and the tailgate control unit 902 controls the upper tailgate and lower tailgate locks; optionally, when it is detected that the window glass is open, the lights are on, or the sunroof is open, the body domain control unit 901 can also control the window glass to be closed, the lights to be turned off, and the sunroof to be closed.

[0133] Figure 10 This is another schematic flow chart of vehicle locking provided in an embodiment of the present application.

[0134] For example, Figure 10 As shown, when the tailgate structure in the vehicle is Figure 3In the structure shown in , when the vehicle is turned off, the four door locks are closed, the lower tailgate is locked, and the key is not in the vehicle, if the user touches the upper tailgate lock switch, the corresponding vehicle executes the vehicle locking instruction, and controls the four door locks to be locked through the body control unit 1001, and the upper tailgate control unit 1002 to control the upper tailgate to be closed, and then controls the upper tailgate to be locked; optionally, when it is detected that the window glass is open, the lights are on, or the sunroof is open, the body domain control unit can also control the window glass to be closed, the lights to be turned off, and the sunroof to be closed.

[0135] In the above technical solution, since the vehicle is in the target state (for example, the vehicle key is not detected, the engine is off, and the doors are closed), receiving the locking command of the target tailgate indicates that the user may be about to leave the vehicle; therefore, controlling the target tailgate and doors to perform the locking action, and controlling the windows, sunroof and lights in the vehicle to be in the closed state can avoid the risk of the owner forgetting to lock the car after closing the tailgate, thereby improving the human-vehicle interaction experience.

[0136] S820: When the target tailgate is in a half-locked state during the locking operation, detecting whether the target tailgate is in a fully locked state within a target preset time period.

[0137] For example, the implementation of S820 can refer to the relevant description of the S220 process in the above example embodiment, which will not be repeated here.

[0138] S830: If the target tailgate is not in the fully locked state within the target preset time period, the target tailgate is controlled to stop performing the locking action.

[0139] For example, the implementation of S830 can refer to the relevant description of the S230 process in the above example embodiment, which will not be repeated here.

[0140] S840: Control the target tailgate to unlock and open it to a preset position.

[0141] The preset position may be a fully open position or a position determined according to the user's height, and is not specifically limited here.

[0142] Exemplarily, after controlling the target tailgate to stop performing the locking action, the tailgate controller initiates an unlocking command, controls the target tailgate to perform the unlocking action, and controls the support rod to open the tailgate to a preset position.

[0143] S850: Determine the target door lock with a self-priming obstacle and control the vehicle to issue an alarm in a preset manner.

[0144] It should be understood that the method for determining the target door lock with self-priming obstacle can refer to the implementation process in the above S220, which will not be repeated here.

[0145] Optionally, the preset method can be a horn reminder, a display reminder, an in-car voice reminder, etc. When the reminder is given through the display or in-car voice, the reminder content may include the target door lock with self-priming failure, such as "Please note, the left door lock of the upper tailgate has a self-priming failure!"

[0146] In some embodiments, the method can also issue an alarm when the number of door locks with self-priming obstacles is greater than a certain value. The specific process can be: determining the number of target door locks; if the number is greater than a preset threshold, controlling the vehicle to issue an alarm in a preset manner.

[0147] Among them, the preset threshold can be set according to the number of door locks. For example, when there are 4 door locks on the tailgate, the preset threshold can be 2. This embodiment of the present application does not make specific limitations on this.

[0148] This alarm prompts the user that the target door lock has a self-priming obstacle.

[0149] If the number of door locks with self-priming failures is greater than the preset threshold, it may affect the normal closing of the vehicle's tailgate, posing a major safety hazard. Therefore, controlling the vehicle to issue an alarm in a preset manner can promptly remind the user that the target door lock has a self-priming problem so that the user can perform repairs in a timely manner.

[0150] In some embodiments, in order to enable the user to quickly locate the cause of the self-priming failure of the target door lock, the method can also perform the following process: detect whether there is an obstacle in the target door lock; if there is an obstacle in the target door lock, send a first prompt message; if there is no obstacle in the target door lock, send a second prompt message.

[0151] The first prompt information is used to prompt the user that there is an obstacle in the target door lock; the second prompt information is used to prompt the user that there is a fault in the target door lock.

[0152] For example, if the sensor detects that there is an obstacle in the target door lock, a voice prompt can be given: "There is an obstacle in the left door lock of the upper tailgate, please clear it in time!"; if no obstacle is detected, a voice prompt can be given: "There is a fault in the left door lock of the upper tailgate, please repair it in time!"

[0153] In the above technical solution, obstacle detection is performed on the target door lock (i.e., the door lock with self-priming obstacle); when there is an obstacle, the user is prompted that there is an obstacle in the target door lock; when there is no obstacle, the user is prompted that there is a fault in the target door lock; this allows the user to promptly understand the specific cause of the self-priming obstacle, avoids manual detection of the cause of the tailgate fault, and improves the user experience.

[0154] Next, combine Figure 11 and Figure 12The vehicle tailgate control method is described with a specific embodiment.

[0155] Figure 11 It is a schematic flow chart of another vehicle tailgate control method provided in an embodiment of the present application.

[0156] For example, Figure 11 As shown, when the tailgate structure in the vehicle is Figure 3 When the structure shown in , when the vehicle's power mode is in the energized state, the lower tailgate executes the closing command action. If any of the lower tailgate locks still fails to reach the full lock signal position after self-priming for 4 seconds, it is determined that the door lock function is abnormal. At the same time, the vehicle will use reminder modes such as horn, display, and in-car voice to remind the lock with the problem. At this time, the lower tailgate automatically unlocks and opens to the full open position; if all the lower tailgate locks reach the full lock position within 4 seconds after self-priming, it is determined that the lower door locking function is normal. At this time, if the upper door closing command is executed, when the upper tailgate lock cannot reach the full lock position after self-priming to the half lock position for 4 seconds, it is determined that the upper door lock function is abnormal. The upper door automatically unlocks and opens to the full open position, and the vehicle uses horn, display, and voice reminders at the same time.

[0157] Figure 12 It is a schematic flow chart of another vehicle tailgate control method provided in an embodiment of the present application.

[0158] For example, Figure 12 As shown, when the tailgate structure in the vehicle is Figure 4 In the structure shown in , when the vehicle's power mode is in the energized state, after the upper and lower tailgates execute the closing command action at the same time, if any lock still does not reach the full lock signal position after self-priming for 4 seconds, it is determined that the door lock function is abnormal. At the same time, the vehicle will use reminder modes such as horn, display, and in-car voice to remind the lock with the problem. At this time, the tailgate corresponding to the problematic lock is unlocked and opened to the fully open position.
