Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of door control, in particular to a split tailgate control system and a vehicle. BACKGROUND

[0002] The rear of a vehicle is usually configured with a trunk, which can be used to store luggage and spare tires, etc. The trunk door is simply referred to as a "tailgate". The opening mode of the tailgate needs to be designed according to the positioning of the vehicle model. Generally speaking, the tailgate adopts a self-upward opening mode. However, in order to fully open the trunk, the existing tailgate can also be designed to be divided into two parts, i.e. an upper "sky door" and a lower "ground door", which are controlled by a control unit to open and close.

[0003] However, the existing sky door and / or ground door of a vehicle may not be able to be normally automatically opened or closed to the correct position when disturbed by external factors. Usually, the sky door and the ground door need to be reset and then closed again, or the position of the sky door and the ground door is detected and collected by the control unit, and the running strategy between the sky door and the ground door is adjusted again through the sharing and interaction of the position information between the sky door and the ground door control units, so as to realize the closing of the sky door and the ground door. However, the above operation and process are relatively complicated, and the sky door and the ground door cannot be quickly closed to the correct position, which results in poor user experience for the vehicle owner or passenger. SUMMARY

[0004] An object of the present application is to provide a split tailgate control system, which can ensure that the second door and the first door can be quickly closed to the correct position under normal and abnormal conditions only by identifying the second door lock related signal without identifying the position of the first door and the second door, so as to solve the problem that the sky door and the ground door of the vehicle cannot be normally automatically opened or closed to the correct position when encountering abnormal conditions as described in the background.

[0005] To achieve the above object, the present application provides the following technical scheme:

[0006] A split tailgate control system, comprising:

[0007] A first door movably arranged between a door opening position and a door closing position of a vehicle body in a hinged manner;

[0008] A second door movably arranged between the door opening position and the door closing position of the vehicle body in a hinged manner;

[0009] A first control unit for controlling the opening and closing of the first door and identifying the position region of the first door in the running track, and identifying the second door lock related signal based on the position region of the first door;

[0010] A second control unit for controlling the opening and closing of the second door;

[0011] The identification point is a designated location point on the trajectory of the first door.

[0012] When the first door reaches the identification point, without the need for the first control unit and the second control unit to share or interact with the position information of the first and second doors, the first control unit controls the first door to perform corresponding opening, closing or parking actions based on the signal feedback from the second door lock, thereby realizing the opening and closing operation of the first and second doors under normal and abnormal conditions.

[0013] Preferably, under normal circumstances, when the first door reaches the identification point, if the first control unit identifies the second door lock related signal at the identification point, the first door will run normally to the closed position and automatically lock at the closed position. If the first control unit cannot identify the second door lock related signal at the identification point, the first door will stop. If the first control unit still cannot identify the second door lock related signal within a preset time, the first control unit will control the first door to remain in a stopped state or run in the reverse direction.

[0014] Preferably, when the second door is fully closed, the first control unit can recognize the corresponding signal of the second door lock. Regardless of the position of the first door, the first control unit can control the first door to close normally.

[0015] Preferably, the split tailgate control system includes a first switch, a second switch, and a third switch. The first switch is electrically connected to a first control unit, the second switch is electrically connected to a second control unit, and the third switch is electrically connected to both the first control unit and the second control unit.

[0016] Preferably, the split tailgate control system includes other control units electrically connected to the second switch. These other control units, like the first control unit, can be used to identify the position area of ​​the first door in the running trajectory. Based on the position area of ​​the first door, the first control unit or other control units determine whether to disable the function of the second switch.

[0017] Preferably, when the first control unit or other control unit detects that the first door is in the area between the detection point and the door opening position, the second control unit can control the second door to close completely through the second switch. After the second door is completely closed, the first control unit can control the first door to close normally.

[0018] Preferably, when the first control unit or other control unit detects that the first door is in any position between the detection point and the closed position due to external factors or other factors, the first control unit or other control unit will disable the function of the second switch. At this time, the second door can be manually closed and the first door can be electrically closed using the first switch, or the first door and the second door can be manually closed.

[0019] Preferably, when the first control unit or other control unit detects that the first door is in any position between the detection point and the closed position due to external factors or other factors, if the first control unit cannot detect the relevant signal of the second door lock, the first door will not operate; if the first control unit still cannot detect the signal change of the second door lock within a certain period of time, the first door will remain in a stopped state or operate in the reverse direction.

[0020] Preferably, it includes a first drive device electrically connected to a first control unit and a second drive device electrically connected to a second control unit. The first drive device is connected between the vehicle body and the first door and is used to drive the first door to perform opening, closing or stopping actions. The second drive device is connected between the vehicle body and the second door and is used to drive the second door to perform opening, closing or stopping actions.

[0021] Another objective of this invention is to provide a vehicle that can open and close the second door and the first door normally when it is disturbed by external factors or encounters abnormal situations, thereby improving the customer experience.

[0022] To achieve the above objectives, the present invention provides the following technical solution:

[0023] An automobile includes the aforementioned split tailgate control system.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention provides a split-type tailgate control system. By cleverly setting a certain calibrated position point in the running trajectory of the first door as an identification point, without the need for information sharing or interaction between the positions of the first and second doors, the first control unit controls the opening and closing of the first door and identifies the position area of ​​the first door in the running trajectory. Based on the identification result, the first door is controlled to perform corresponding opening, closing, or parking actions, thereby realizing the opening and closing operation of the first and second doors under normal and abnormal conditions. This simplifies the control logic and makes the operation simple and convenient. Furthermore, based on the positional relationship between the first door and the identification point, the first control unit or other control units determine whether to disable the function of the second switch, ensuring that both the second and first doors can open and close normally under abnormal conditions, especially ensuring that both the second and first doors are closed properly, while improving the safety of door use.

[0026] 2. The present invention provides a car that can quickly open and close the second door and the first door when it is disturbed by external factors or encounters abnormal situations, thereby improving the user experience of the owner or passengers. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figures 1-2 This embodiment discloses a split-type tailgate control system, including a first door 1, a second door 2, an identification point 13, a first control unit 7, and a second control unit 8. The first door 1 is hinged and movably disposed between the open and closed positions of the vehicle body; the second door 2 is hinged and movably disposed between the open and closed positions of the vehicle body. The identification point 13 is a calibrated position point in the running trajectory of the first door 1; the first control unit 7 is electrically connected to the first door 1 and is used to control the opening and closing of the first door 1 and identify the position area of ​​the first door 1 in the running trajectory, and at the same time, it identifies the relevant signals of the second door lock 6 based on the position area of ​​the first door 1; the second control unit 8 is electrically connected to the second door 2 and is used to control the opening and closing of the second door 2.

[0039] When the first door 1 reaches the identification point 13, without the need for the first control unit 7 and the second control unit 8 to share or interact with the position information of the first door 1 and the second door 2, the first control unit 7 controls the first door 1 to perform corresponding opening, closing or parking actions based on the signal feedback from the second door lock 6, thereby realizing the opening and closing operation of the first door 1 and the second door 2 under normal and abnormal conditions.

[0040] The position of the identification point 13 on the running trajectory of the first door 1 is not fixed. It can be customized through calibration according to the actual application situation, as long as it can meet the conditions for normal opening and closing of the first door 1 and the second door 2.

[0041] In this embodiment, the function of identification point 13 is as follows: (Please refer to...) Figure 3 Under normal circumstances, when the user closes the first door 1 and the second door 2, if the first control unit 7 detects a signal related to the second door lock 6 at the recognition point 13 when the first door 1 reaches the recognition point 13, the first door 1 will run normally to the closed position and automatically lock in the closed position. Please refer to [link to relevant documentation]. Figure 4When the first door 1 reaches the identification point 13, if the first control unit 7 cannot identify the relevant signal of the second door lock 6 at the identification point 13, that is, if the second door 2 is not closed normally, the first door 1 will stop. If the first control unit 7 still cannot identify the relevant signal of the second door lock 6 within a preset time (which can be customized), the first control unit 7 will control the first door 1 to remain in a stopped state or run in the opposite direction.

[0042] To address the problem of tailgates failing to close properly in existing technologies, this embodiment provides a novel tailgate control system. By cleverly setting a specific calibrated position point on the trajectory of the first door 1 as identification point 13, the first door 1 will stop when it reaches identification point 13. Based on the position area of ​​the first door 1, the first control unit 7 identifies the position between the first door 1 and identification point 13, as well as the relevant signals of the second door lock 6, ensuring that both the second door 2 and the first door 1 can open and close properly, especially ensuring that the second door 2 and the first door 1 are closed properly. This eliminates the need for information sharing and interaction regarding the positions of the first door 1 and the second door 2, simplifying the control logic and making operation simple and convenient, without requiring the reset of the positions of the second door 2 and the first door 1 before closing.

[0043] In this embodiment, a first pivot is provided on the upper part of the vehicle body, and the first door 1 is hinged to the first pivot and rotates around the first pivot to open and close; a second pivot is provided on the lower part of the vehicle body, and the second door 2 is hinged to the second pivot and rotates around the second pivot to open and close.

[0044] Please see Figures 1-2 The split tailgate control system includes a first drive unit 3 electrically connected to a first control unit 7. The first drive unit 3 is connected between the vehicle body and the first door 1, and is used to drive the first door 1 to perform opening, closing, or stopping actions. The split tailgate control system also includes a second drive unit 4 electrically connected to a second control unit 8. The second drive unit 4 is connected between the vehicle body and the second door 2, and is used to drive the second door 2 to perform opening, closing, or stopping actions. In this embodiment, both the first drive unit 3 and the second drive unit 4 use electric struts, making driving more convenient and flexible.

[0045] The split tailgate control system includes a first switch 10, a second switch 11, and a third switch 12. The first switch 10 is electrically connected to the first control unit 7 and is used to control the start and stop of the first drive unit 3 to open and close the first door 1. The second switch 11 is electrically connected to the second control unit 8 and is used to control the start and stop of the second drive unit 4 to open and close the second door 2. The third switch 12 is electrically connected to both the first control unit 7 and the second control unit 8, and serves as a master switch to simultaneously control the start and stop of both the first drive unit 3 and the second drive unit 4.

[0046] Please see Figure 2 The split tailgate control system includes another control unit 9 electrically connected to the second switch 11. The other control unit 9, like the first control unit 7, can be used to identify the position area of ​​the first door 1 in the running trajectory.

[0047] Under normal circumstances, when the user uses the third switch 12 to close the first door 1 and the second door 2, the first door 1 and the second door 2 close in sequence or simultaneously at different speeds. When the first door 1 reaches the identification point 13, the first control unit 7 will identify the signal of the second door lock 6.

[0048] Example 2

[0049] Please see Figure 5 When the second door 2 is fully closed, the first door 1 can be closed by simply using the first switch 10. That is, at this time, the first control unit 7 can recognize the corresponding signal of the second door lock 6. No matter what position the first door 1 is in, the first control unit 7 can control the first door 1 to close normally.

[0050] Example 3

[0051] Please see Figure 6 When the first door 1 is in the area between the recognition point 13 and the opening position, for example, when the first door 1 is opened to the user's desired opening degree and the user pauses the opening of the first door 1; or when the user directly and manually closes the first door 1 to this area; or when the first door 1 stops in this area due to external obstacles or other factors, the second door 2 can be closed by simply using the second switch 11; that is to say, if the first control unit 7 or other control unit 9 recognizes that the first door 1 is in the area between the recognition point 13 and the opening position, the second door 2 can be completely closed normally by using the second switch 11. After the second door 2 is completely closed, the first control unit 7 can control the first door 1 to close normally.

[0052] Example 4

[0053] The identification point also serves to determine, based on the position area of ​​the first door 1, whether to disable the function of the second switch 11 in case of an abnormal situation, i.e., when the first door 1 and the second door 2 cannot be opened or closed normally.

[0054] In case of any abnormal situation, such as the second door 2 not being fully closed, please refer to [the relevant documentation]. Figure 7 If the first door 1 is located in the area between the identification point 13 and the door opening position, the first door 1 is closed by using the first switch 10. The first door 1 will run to the identification point 13 and then stop because the first control unit 7 cannot identify the corresponding signal of the second door lock 6. If the first control unit 7 cannot identify the signal change of the second door lock 6 within a certain period of time (which can be customized), the first drive device 3 is controlled to remain in the stopped state or run in the reverse direction.

[0055] Example 5

[0056] Please see Figure 8 In the event of the same abnormality, when the first door 1 is in the area between the identification point 13 and the closed position, if the first control unit 7 cannot identify the relevant signal of the second door lock 6, the first door 1 will not operate; if the first control unit 7 still cannot identify the signal change of the second door lock 6 within a certain period of time (which can be customized), the first drive device 3 will be controlled to remain in a stopped state or run in the reverse direction, that is, the first door 1 will remain in a stopped state or run in the reverse direction.

[0057] Please see Figure 8 In the event of the same anomaly, when the first control unit 7 or other control unit 9 detects that the first door 1 is in any position between the recognition point 13 and the closed position due to external factors or other factors, the first control unit 7 or other control unit 9 will disable the function of the second switch 11. At this time, the second door 2 cannot be electrically operated using the second switch 11. To close the first door 1 and the second door 2, the positions of the first door 1 and the second door 2 can be manually adjusted to... Figure 3 , Figure 6 and Figure 7 The location shown, and as described above. Figure 3 , Figure 6 and Figure 7 The relevant operations shown can be used to close the first door 1 and the second door 2. At this time, you can also manually close the second door 2 and then use the first switch to electrically close the first door 1; or you can directly manually close the first door 1 and the second door 2.

[0058] The area between identification point 13 and the door opening position does not include the location of identification point 13 at this point, but includes the door opening position; the area between identification point 13 and the door closing position includes both the location of identification point 13 and the door closing position.

[0059] It is understandable that, under any of the above circumstances, if the user uses the third switch 12 for control, since the third switch 12 also controls the operation of the first door 1 and the second door 2 respectively through the first control unit 7 and the second control unit 8, the results are consistent with the corresponding situations described above.

[0060] The working principle of the split tailgate control system of the present invention is as follows: When the user uses the third switch 12 to close the first door 1 and the second door 2, the first door 1 and the second door 2 close in sequence or simultaneously at different speeds. If the first control unit 7 recognizes the relevant signal of the second door lock 6, the first door 1 will operate normally to the closed position, and the second door 2 will also operate normally to the closed position. When the first door 1 reaches the closed position, the first door lock 5 locks and secures the first door 1. At the same time, the second door lock 6 also locks and secures the second door 2 when the second door 2 reaches the closed position. When the first door 1 is about to open, the first door lock 5 unlocks and releases the first door 1. When the second door 2 is about to open, the second door lock 6 unlocks and releases the second door 2.

[0061] Example 6

[0062] This embodiment discloses a car that can open and close the second door 2 and the first door 1 normally when it is interfered with by external factors or encounters abnormal situations, thereby improving the customer experience. The car includes the split tailgate control system.

[0063] In summary, this invention not only ensures that both the second door 2 and the first door 1 can open and close normally by cleverly setting the identification point 13, but also improves the safety of door use by manually closing the first door 1 and the second door 2 in the event of an electronic malfunction. It realizes the switching between automatic and semi-automatic door functions, simplifies the control logic, eliminates the need for interaction and sharing between door positions, and solves the problem that existing automotive top and bottom doors cannot close quickly and completely.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
