[0035] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0036] Reference will be made below to Figures 1 - 3 describe a split - door system according to an embodiment of the present invention.

[0037] Referring to Figures 1 - 3 , a split - door system according to an embodiment of the first aspect of the present invention includes a first door 21, a second door 11, a first distance detector 25, a second distance detector 15, a first driver 23, a second driver 13, a first control unit 24, and a second control unit 14. Both the first door 21 and the second door 11 are adapted to be movably connected to the vehicle body. During the process of the first door 21 and the second door 11 moving to the open position, the first door 21 and the second door 11 move away from each other. During the process of the first door 21 and the second door 11 moving to the closed position, the first door 21 and the second door 11 move towards each other.

[0038] For example, the vehicle body can play a role of supporting and fixing for the first door 21, the first distance detector 25, the second distance detector 15, the first driver 23, the second driver 13, the first control unit 24, and the second control unit 14. For example, the first door 21 is connected to the vehicle body through a first hinge 214, and the second door 11 is connected to the vehicle body through a second hinge 114 to realize the movable connection between the first door 21 and the vehicle body and between the second door 11 and the vehicle body, and the connection manners between the first door 21 and the vehicle body and between the second door 11 and the vehicle body are simple and have strong stability.

[0039] The first car door lock 22 is used to cooperate with the first car door 21 to fix the first car door 21 to the vehicle body. A first door lock sensor is provided on the first car door lock 22, and the first door lock sensor is used to collect and send a first car door lock status signal. The first car door lock status signal includes a first closing signal and a first release signal. The second car door lock 12 is used to cooperate with the second car door 11 to fix the second car door 22 to the vehicle body. A second door lock sensor is provided on the second car door lock 12, and the second door lock sensor is used to collect and send a second car door lock status signal. The second car door lock status signal includes a second closing signal and a second release signal. By respectively providing door lock sensors on the first car door lock 22 and the second car door lock 12, the corresponding car door lock status signals can be collected in real time and accurately, so that the control unit can determine whether each car door is in the open position or the closed position, and avoid the collision between the first car door 21 and the second car door 11 caused by misjudgment of the car door lock status.

[0040] Optionally, the first car door lock 22 includes a first lock catch 211 and a first lock body 212. The second car door lock 12 includes a second lock catch 111, a second lock body 112, a first switch 213 and a second switch 113. The first lock catch 211 cooperates with the first lock body 212. The first switch 213 is arranged on the first car door 21 and the first switch 213 is used to control the connection or disconnection between the first lock catch 211 and the first lock body 212. The second lock catch 111 cooperates with the second lock body 112. The second switch 113 is arranged on the second car door 11 and the second switch 113 is used to control the connection or disconnection between the second lock catch 111 and the second lock body 112. One of the first lock catch 211 and the first lock body 212 is installed on the vehicle body, and the other of the first lock catch 211 and the first lock body 212 is installed on the first car door 21. One of the second lock catch 111 and the second lock body 112 is installed on the vehicle body, and the other of the second lock catch 111 and the second lock body 112 is installed on the second car door 11.

[0041] When the first car door 21 is in the closed position, the stable connection between the first car door 21 and the vehicle body can be realized through the cooperation of the first lock catch 211 and the first lock body 212, so that the first car door 21 can be more stably maintained in the closed position. When the second car door 11 is in the closed position, the stable connection between the second car door 11 and the vehicle body can be realized through the cooperation of the second lock catch 111 and the second lock body 112, so that the second car door 11 can be more stably maintained in the closed position.

[0042] The first distance detector 25 is disposed on the first vehicle door 21. The first distance detector 25 is used to detect and send a first vehicle door obstacle signal, where the first vehicle door obstacle signal is the distance between the first vehicle door 21 and an obstacle on the movement path of the first vehicle door 21. The second distance detector 15 is disposed on the second vehicle door 11. The second distance detector 15 is used to detect and send a second vehicle door obstacle signal, where the second vehicle door obstacle signal is the distance between the second vehicle door 11 and an obstacle on the movement path of the second vehicle door 11. The first driver 23 is connected to the first vehicle door 21 to drive the first vehicle door 21 to move. The second driver 13 is connected to the second vehicle door 11 to drive the second vehicle door 11 to move. The first control unit 24 is used to receive a door opening / closing instruction, the first vehicle door obstacle signal detected by the first distance detector 25, and the second vehicle door lock state signal, and control the first driver 23 according to the received door opening / closing instruction, first vehicle door obstacle signal, and second vehicle door lock state signal. The second control unit 14 is used to receive a door opening / closing instruction and the second vehicle door obstacle signal detected by the second distance detector 15, and control the second driver 13 according to the received door opening / closing instruction and second vehicle door obstacle signal.

[0043] For example, the first control unit 24 is electrically connected to the first distance detector 25 through a first wire harness 215. The first control unit 24 can control the operation of the first driver 23 according to the first vehicle door obstacle signal detected by the first distance detector 25, and then control the movement of the first vehicle door 21 to avoid collision between the first vehicle door 21 and an obstacle. The second control unit 14 is electrically connected to the second distance detector 15 through a second wire harness. The second control unit 14 can control the operation of the second driver 13 according to the second vehicle door obstacle signal detected by the second distance detector 15, and then control the movement of the second vehicle door 11 to avoid collision between the second vehicle door 11 and an obstacle.

[0044] For example, if the first distance detector 25 detects an obstacle on the movement path of the first vehicle door 21 and the distance between the obstacle and the first vehicle door 21 is greater than or equal to a preset safety distance, the first distance detector 25 can feedback the information to the first control unit 24. The first control unit 24 can control the first vehicle door 21 to continue moving through the first driver 23; when the distance between the obstacle and the first vehicle door 21 is less than the preset safety distance, the first control unit 24 can control the first vehicle door 21 to stop moving through the first driver 23 to avoid collision between the first vehicle door 21 and the obstacle; if the first distance detector 25 detects no obstacle on the movement path of the first vehicle door 21, the first distance detector 25 can feedback the information to the first control unit 24. The first control unit 24 can control the first vehicle door 21 to move to the open position or the closed position through the first driver 23.

[0045] Among them, if the second vehicle door 11 appears in the movement path of the first vehicle door 21, the second vehicle door 11 can be detected by the first distance detector 25 as an obstacle on the movement path of the first vehicle door 21. Of course, the obstacles on the movement path of the first vehicle door 21 can also be people, animals, etc., but not limited thereto. Through the above control logic of the first vehicle door 21, the first vehicle door 21 can be effectively prevented from colliding with obstacles.

[0046] For example, if the second distance detector 15 detects that there is an obstacle on the movement path of the second vehicle door 11 and the distance between the obstacle and the second vehicle door 11 is greater than or equal to the preset safety distance, the second distance detector 15 can feedback the information to the second control unit 14, and the second control unit 14 can control the second vehicle door 11 to continue moving through the second driver 13; when the distance between the obstacle and the second vehicle door 11 is less than the preset safety distance, the second control unit 14 can control the second vehicle door 11 to stop moving through the second driver 13 to avoid the second vehicle door 11 from colliding with the obstacle; if the second distance detector 15 detects that there is no obstacle on the movement path of the second vehicle door 11, the second distance detector 15 can feedback the information to the second control unit 14, and the second control unit 14 can control the second vehicle door 11 to move to the open position or the closed position through the second driver 13.

[0047] Among them, if the first vehicle door 21 appears in the movement path of the second vehicle door 11, the first vehicle door 21 can be detected by the second distance detector 15 as an obstacle on the movement path of the second vehicle door 11. Of course, the obstacles on the movement path of the second vehicle door 11 can also be people, animals, etc., but not limited thereto. Through the above control logic of the second vehicle door 11, the second vehicle door 11 can be effectively prevented from colliding with obstacles.

[0048] Among them, the open positions of the first vehicle door 21 and the second vehicle door 11 include the maximum open position, and the maximum open position refers to the position where the first vehicle door 21 or the second vehicle door 11 rotates the maximum angle along the set path from the closed position.

[0049] By providing a first distance detector 25 on the first vehicle door 21 for detecting whether there is an obstacle on the movement path of the first vehicle door 21, the first control unit 24 is electrically connected to both the first driver 23 for driving the movement of the first vehicle door 21 and the first distance detector 25, and by providing a second distance detector 15 on the second vehicle door 11 for detecting whether there is an obstacle on the movement path of the second vehicle door 11, the second control unit 14 is electrically connected to both the second driver 13 for driving the movement of the second vehicle door 11 and the second distance detector 15, the independent control of the first vehicle door 21 and the second vehicle door 11 can be achieved.

[0050] Moreover, there is no need for the first control unit 24 and the second control unit 14 to exchange position information. By determining whether there are obstacles on the movement paths of the first door 21 or the second door 11 according to the first distance detector 25 or the second distance detector 15, the first control unit 24 or the second control unit 14 can control the movement of the first door 21 or the second door 11 via the first driver 23 or the second driver 13. While effectively avoiding collisions between the first door 21 and the second door 11, the control logic of the first door 21 and the second door 11 can be made simpler. To a certain extent, this can improve the control efficiency of the first control unit 24 or the second control unit 14. When the corresponding distance detector detects an obstacle, the first control unit 24 or the second control unit 14 can more quickly control the corresponding driver to move, so as to control whether the first door 21 or the second door 11 moves.

[0051] For the split door system according to an embodiment of the present invention, the first door 21 is provided with a first distance detector 25 for detecting whether there are obstacles on the movement path of the first door 21, and the second door 11 is provided with a second distance detector 15 for detecting whether there are obstacles on the movement path of the second door 11. If there are obstacles, the first control unit 24 and the second control unit 14 can automatically adjust the first door 21 or the second door 11 to stop moving according to the corresponding door obstacle signals detected by the corresponding distance detectors, thereby effectively avoiding collisions between the first door 21 or the second door 11 and the obstacles. Moreover, there is no need for the first control unit 24 and the second control unit 14 to exchange the position information of the first door 21 and the second door 11, and independent control of the first door 21 by the first control unit 24 and the second door 11 by the second control unit 14 can be achieved, making the control logic of the first door 21 and the second door 11 simpler.

[0052] Referring to Figures 1 - 3 , according to some embodiments of the present invention, the first control unit 24 is configured to receive a door opening / closing instruction, a first door obstacle signal, and a second door lock state signal, and control the first driver 23 according to the first door obstacle signal and the second door lock state signal, including:

[0053] When the first control unit 24 receives a door opening / closing instruction, the first control unit 24 is configured to determine, according to the received first door obstacle signal, whether the distance between the first door 21 and the obstacle is greater than or equal to a preset safety distance. When there is an obstacle on the movement path of the first door 21, by determining the relationship between the distance between the first door 21 and the obstacle and the preset safety distance, collisions between the first door 21 and the obstacle can be effectively prevented;

[0054] When it is determined that the distance between the first vehicle door 21 and the obstacle is greater than or equal to a preset safety distance, the first control unit 24 is configured to control the first driver 23 to drive the first vehicle door 21 to move; when it is determined that the distance between the first vehicle door 21 and the obstacle is less than the preset safety distance, the first control unit 24 is configured to control the first driver 23 not to move.

[0055] If the first distance detector 25 detects an obstacle in the movement path of the first vehicle door 21 and the distance between the obstacle and the first vehicle door 21 is greater than or equal to the preset safety distance, the first distance detector 25 can feedback the information to the first control unit 24, and the first control unit 24 can control the first vehicle door 21 to continue to move through the first driver 23; when the distance between the obstacle and the first vehicle door 21 is less than the preset safety distance and the second vehicle door lock state signal is the second release signal, it indicates that the second vehicle door is in the open position, and the first control unit 24 can control the first vehicle door 21 to stop moving through the first driver 23 to avoid collision between the first vehicle door 21 and the second vehicle door or other obstacles.

[0056] Through the above control logic of the first vehicle door 21, collision between the first vehicle door 21 and the obstacle can be effectively avoided.

[0057] Refer to Figures 1 - 3 , according to some embodiments of the present invention, the first control unit 24 is used to receive a door opening / closing instruction, a first vehicle door obstacle signal and a second vehicle door lock state signal, and control the first driver 23 according to the first vehicle door obstacle signal and the second vehicle door lock state signal, including:

[0058] When it is determined that the distance between the first vehicle door 21 and the obstacle is less than the preset safety distance and the second vehicle door lock state signal is the second closing signal, it indicates that the second vehicle door is in the closed position, and the first control unit 24 is configured to control the first driver 23 to move, which can effectively avoid collision between the first vehicle door 21 and the second vehicle door 11.

[0059] Refer to Figures 1 - 3 , according to some embodiments of the present invention, it further includes an alarm reminder device. The first control unit 24 is electrically connected to the alarm reminder device, and the first control unit 24 is configured to control the alarm reminder device to give an alarm reminder when it is determined that the distance between the first vehicle door 21 and the obstacle is less than the preset safety distance and the duration of this state reaches the preset duration.

[0060] When it is determined that the distance between the first vehicle door 21 and the obstacle is less than the preset safety distance and the duration of this state reaches the preset time period, it indicates that the obstacle has not moved within the preset time period. At this time, the first control unit 24 controls the alarm reminder device to give an alarm reminder, which can play a reminder role for the user. For example, it can enable the user to manually remove the obstacle so that the first vehicle door 21 can move more smoothly to the open position or the closed position.

[0061] Referring to Figures 1 - 3 , according to some embodiments of the present invention, the second control unit 14 is configured to receive the door opening / closing instruction and the second vehicle door obstacle signal detected by the second distance detector 15, and control the second driver 13 according to the received second vehicle door obstacle signal, including:

[0062] When the second control unit 14 receives the door opening / closing instruction, the second control unit 14 is configured to judge whether the distance between the second vehicle door 11 and the obstacle is greater than or equal to the preset safety distance according to the received second vehicle door obstacle signal. When there is an obstacle on the movement path of the second vehicle door 11, by judging the relationship between the distance between the second vehicle door 11 and the obstacle and the preset safety distance, it is possible to effectively prevent the second vehicle door 11 from colliding with the obstacle;

[0063] When it is judged that the distance between the second vehicle door 11 and the obstacle is greater than or equal to the preset safety distance, the second control unit 14 is configured to control the first driver 23 to drive the second vehicle door 11 to move; when it is judged that the distance between the second vehicle door 11 and the obstacle is less than the preset safety distance, the second control unit 14 is configured to control the second driver 13 not to move.

[0064] If the second distance detector 15 detects that there is an obstacle on the movement path of the second vehicle door 11 and the distance between the obstacle and the second vehicle door 11 is greater than or equal to the preset safety distance, the second distance detector 15 can feed back the information to the second control unit 14, and the second control unit 14 can control the second vehicle door 11 to continue moving through the second driver 13; when the distance between the obstacle and the second vehicle door 11 is less than the preset safety distance, the second control unit 14 can control the second vehicle door 11 to stop moving through the second driver 13 to avoid the second vehicle door 11 from colliding with the obstacle.

[0065] Through the above control logic of the second vehicle door 11, it is possible to effectively avoid the second vehicle door 11 from colliding with the obstacle.

[0066] Referring to Figures 1 - 3, according to some embodiments of the present invention, it further includes an alarm reminder device. The second control unit 14 is electrically connected to the alarm reminder device. The second control unit 14 is configured to control the alarm reminder device to give an alarm reminder when it is determined that the distance between the second door 11 and the obstacle is less than a preset safety distance and the duration of this state reaches a preset time length.

[0067] When it is determined that the distance between the second door 11 and the obstacle is less than a preset safety distance and the duration of this state reaches a preset time length, it indicates that the obstacle has not moved within the preset time length. At this time, the second control unit 14 controls the alarm reminder device to give an alarm reminder, which can play a reminder role for the user. For example, it can enable the user to manually remove the obstacle so that the second door 11 can move more smoothly to the open position or the closed position.

[0068] Refer to Figures 1 - 3 , according to some embodiments of the present invention, the first distance detector 25 is arranged at the edge of the first door 21, which can make the detection range of the first distance detector 25 cover the movement path of the first door 21 as much as possible. During the process of the first door 21 moving to the open position or the closed position, by arranging the first distance detector 25 at the edge of the first door 21, the entire movement path of the first door 21 from the start of movement to the stop can be detected by the first distance detector 25, thereby effectively avoiding the first door 21 from colliding with the obstacles on its movement path.

[0069] Refer to Figures 1 - 3 , according to some embodiments of the present invention, the second distance detector 15 is arranged at the edge of the second door 11, which can make the detection range of the second distance detector 15 cover the movement path of the second door 11 as much as possible. During the process of the second door 11 moving to the open position or the closed position, by arranging the second distance detector 15 at the edge of the second door 11, the entire movement path of the second door 11 from the start of movement to the stop can be detected by the second distance detector 15, thereby effectively avoiding the second door 11 from colliding with the obstacles on its movement path.

[0070] Refer to Figures 1 - 3 , according to some embodiments of the present invention, the first distance detector 25 is arranged at the edge of the first door 21; and the second distance detector 15 is arranged at the edge of the second door 11, which can make the detection ranges of the first distance detector 25 and the second distance detector 15 cover the movement paths of the first door 21 and the second door 11 as much as possible, thereby effectively avoiding the first door 21 or the second door 11 from colliding with the obstacles on their movement paths.

[0071] Refer to Figures 1 - 3, according to some embodiments of the present invention, the first distance detector 25 is disposed at one end of the first vehicle door 21 close to the second vehicle door 11, which can better detect this part of the area between the first vehicle door 21 and the second vehicle door 11, so as to effectively prevent the first vehicle door 21 and the second vehicle door 11 from colliding with each other.

[0072] Referring to Figures 1 - 3 , according to some embodiments of the present invention, the second distance detector 15 is disposed at one end of the second vehicle door 11 close to the first vehicle door 21, which can better detect this part of the area between the first vehicle door 21 and the second vehicle door 11, so as to effectively prevent the first vehicle door 21 and the second vehicle door 11 from colliding with each other.

[0073] For example, the first distance detector 25 is disposed at one end of the first vehicle door 21 close to the second vehicle door 11, and the second distance detector 15 is disposed at one end of the second vehicle door 11 close to the first vehicle door 21. During the process of the first vehicle door 21 and the second vehicle door 11 moving to the closed position, the first vehicle door 21 and the second vehicle door 11 move towards each other. By disposing the first distance detector 25 at one end of the first vehicle door 21 close to the second vehicle door 11 and the second distance detector 15 at one end of the second vehicle door 11 close to the first vehicle door 21, the first vehicle door 21 and the second vehicle door 11 can be effectively prevented from colliding with each other.

[0074] Referring to Figures 1 - 3 , according to some embodiments of the present invention, two first distance detectors 25 are provided on the first vehicle door 21. One first distance detector 25 is disposed on the outer side of the first vehicle door 21, and the other first distance detector 25 is disposed on the inner side of the first vehicle door 21. One first distance detector 25 is disposed on the outer side of the first vehicle door 21. During the process of the first vehicle door 21 moving to the open position, the first distance detector 25 disposed on the outer side of the first vehicle door 21 can detect whether there are obstacles on the path of the first vehicle door 21 moving towards the open position, while the other first distance detector 25 is disposed on the inner side of the first vehicle door 21. During the process of the first vehicle door 21 moving to the closed position, the first distance detector 25 disposed on the inner side of the first vehicle door 21 can detect whether there are obstacles on the path of the first vehicle door 21 moving towards the closed position. By disposing the two first distance detectors 25 on the inner and outer sides of the first vehicle door 21 respectively, the first distance detector 25 can detect whether there are obstacles in all directions and paths of the movement of the first vehicle door 21 as much as possible, so as to increase the detection range of the first distance detector 25 and effectively prevent the first vehicle door 21 from colliding with obstacles.

[0075] Referring to Figures 1 - 3, according to some embodiments of the present invention, two second distance detectors 15 are provided on the second door 11.

One of the second distance detectors 15 is provided on the outer side of the second door 11. During the movement of the second door 11 to the open position, the second distance detector 15 provided on the outer side of the second door 11 can detect whether there are obstacles on the path of the second door 11 moving towards the open position. The other second distance detector 15 is provided on the inner side of the second door 11. During the movement of the second door 11 to the closed position, the second distance detector 15 provided on the inner side of the second door 11 can detect whether there are obstacles on the path of the second door 11 moving towards the closed position. By providing the two second distance detectors 15 on the inner and outer sides of the second door 11 respectively, the second distance detector 15 can detect whether there are obstacles in all directions and paths of the movement of the second door 11 as much as possible, so as to increase the detection range of the second distance detector 15 and effectively avoid the second door 11 from colliding with obstacles.

[0076] Refer to Figures 1 - 3 , according to some embodiments of the present invention, when the door opening and closing instruction received by the first control unit 24 is a closing instruction, the first distance detector 25 provided on the inner side of the first door 21 is used to detect and send a first door obstacle signal. At this time, the first distance detector 25 provided on the outer side of the first door 21 stops working. The first distance detector 25 provided on the inner side of the first door 21 is used to detect and send a first door obstacle signal to the first control unit 24. The first control unit 24 is used to control the first driver 23 according to the received door opening and closing instruction, the first door obstacle signal sent by the first distance detector 25 provided on the inner side of the first door 21, and the second door lock state signal.

[0077] When the door opening and closing instruction received by the first control unit 24 is an opening instruction, at this time, the first distance detector 25 provided on the inner side of the first door 21 stops working. The first distance detector 25 provided on the outer side of the first door 21 is used to detect and send a first door obstacle signal. The first distance detector 25 provided on the outer side of the first door 21 is used to detect and send a first door obstacle signal to the first control unit 24. The first control unit 24 is used to control the first driver 23 according to the received door opening and closing instruction, the first door obstacle signal sent by the first distance detector 25 provided on the outer side of the first door 21, and the second door lock state signal.

[0078] When the door opening / closing instruction received by the second control unit 14 is a door closing instruction, the second distance detector 15 provided on the inner side of the second vehicle door 11 is used to detect and send a first vehicle door obstacle signal. At this time, the second distance detector 15 provided on the outer side of the second vehicle door 11 stops working. The second distance detector 15 provided on the inner side of the second vehicle door 11 is used to detect and send a second vehicle door obstacle signal to the second control unit 14. The second control unit 14 is used to control the second driver 13 according to the received door opening / closing instruction and the second vehicle door obstacle signal sent by the second distance detector 15 provided on the inner side of the second vehicle door 11.

[0079] When the door opening / closing instruction received by the second control unit 14 is a door opening instruction, the second distance detector 15 provided on the outer side of the second vehicle door 11 is used to detect and send a second vehicle door obstacle signal. At this time, the second distance detector 15 provided on the inner side of the second vehicle door 11 stops working. The second distance detector 15 provided on the outer side of the second vehicle door 11 is used to detect and send a second vehicle door obstacle signal to the second control unit 14. The second control unit 14 is used to control the second driver 13 according to the received door opening / closing instruction and the second vehicle door obstacle signal sent by the second distance detector 15 provided on the outer side of the second vehicle door 11.

[0080] By providing two first distance detectors 25 on the inner and outer sides of the first vehicle door 21 respectively and two second distance detectors 15 on the inner and outer sides of the second vehicle door 11 respectively, the first distance detector 25 and the second distance detector 15 can detect whether there are obstacles in all directions and paths of the movement of the first vehicle door 21 and the second vehicle door 11 as much as possible, so as to increase the detection range of the first distance detector 25 and the second distance detector 15 and effectively avoid the first vehicle door 21 and the second vehicle door 11 from colliding with obstacles.

[0081] Refer to Figures 1 - 3 According to some embodiments of the present invention, the first control unit 24 and the second control unit 14 are separately provided, and each control unit independently controls the corresponding vehicle door. In this way, when one of the control units fails, it will not affect the normal operation of the other control unit, improving the reliability of the vehicle. And the separate setting of the two control units is convenient for the maintenance or replacement of each control unit. For example, when the first control unit 24 needs to be maintained or replaced, only the first control unit 24 needs to be repaired or replaced alone, without affecting the normal operation of the second control unit 14.

[0082] For example, the first control unit 24 and the second control unit 14 are separately provided and operate independently. At this time, there is no information interaction between the first control unit 24 and the second control unit 14, making the control systems of the first vehicle door 21 and the second vehicle door 11 independent respectively. The first control unit 24 or the second control unit 14 controls the movement path and direction of the first vehicle door 21 or the second vehicle door 11 only according to the information measured by the corresponding distance detector, which can simplify the control logic of the first vehicle door 21 and the second vehicle door 11.

[0083] Correspondingly, it can also be that the first control unit 24 and the second control unit 14 are separately provided, but the first control unit 24 and the second control unit 14 are communicatively connected. At this time, there is information interaction between the first control unit 24 and the second control unit 14, and the other control unit can adjust its own control logic according to the information provided by one of the control units. For example, when the first control unit 24 controls the first vehicle door 21 to move towards the open position or the closed position through the first driver 23, through the communicative connection between the first control unit 24 and the second control unit 14, the second control unit 14 can adjust the action of the second vehicle door 11 according to the position information of the first vehicle door 21 interacted by the first control unit 24, avoiding collision when the first vehicle door 21 and the second vehicle door 11 move towards the open position or the closed position at the same time.

[0084] Referring to Figures 1 - 3 , according to some embodiments of the present invention, the first control unit 24 and the second control unit 14 are integrated into one body, and two vehicle doors are controlled by one control unit, reducing the number of hardware devices and simplifying the structure of the split vehicle door system, which can reduce the manufacturing cost of the vehicle to a certain extent.

[0085] Referring to Figures 1 - 3 , according to some embodiments of the present invention, both the first distance detector 25 and the second distance detector 15 are radar detectors. Radar detectors are not affected by environmental factors such as light and dust, have low requirements for the environment, and can provide relatively accurate distance measurements. When it is recognized that there are obstacles in the movement path of the first vehicle door 21 or the second vehicle door 11, it can quickly detect and provide the distance information between the obstacle and the first vehicle door 21 or the second vehicle door 11 to the first control unit 24 or the second control unit 14. By both the first distance detector 25 and the second distance detector 15 being radar detectors, relatively accurate distance measurement information and obstacle recognition capabilities can be provided, which is beneficial to improving the accuracy of the first distance detector 25 and the second distance detector 15.

[0086] Referring to Figures 1 - 3, according to some embodiments of the present invention, the first vehicle door 21 and the second vehicle door 11 are arranged along the up-and-down direction, and the second vehicle door 11 is located above the first vehicle door 21. For example, when the first vehicle door 21 and the second vehicle door 11 are in the closed position, the lower end of the first vehicle door 21 cooperates with the upper end of the second vehicle door 11, which can enhance the overall sealing effect of the first vehicle door 21 and the second vehicle door 11 and reduce or avoid the possibility of dust or water entering the vehicle interior through the gap between the first vehicle door 21 and the second vehicle door 11.

[0087] When the first vehicle door 21 and the second vehicle door 11 are both in the closed position, the lower end of the first vehicle door 21 covers the outside of the upper end of the second vehicle door 11. When the first vehicle door 21 and the second vehicle door 11 are in the closed position, the lower side wall of the lower end of the first vehicle door 21 constitutes the first mating side wall 216, and the upper side wall of the upper end of the second vehicle door 11 constitutes the second mating side wall 115. The first mating side wall 216 and the second mating side wall 115 are arranged opposite to each other and both the first mating side wall 216 and the second mating side wall 115 extend obliquely downward in the direction from the inside to the outside, so that at least part of the second mating side wall 115 is located outside the first mating side wall 216, which can enhance the sealing effect of the first vehicle door 21 and the second vehicle door 11 and reduce the possibility of dust or water entering the vehicle interior through the gap between the first vehicle door 21 and the second vehicle door 11.

[0088] Refer to Figures 1 - 3 , the vehicle according to the second aspect embodiment of the present invention includes the split vehicle door system according to the first aspect embodiment of the present invention.

[0089] For the vehicle according to the embodiment of the present invention, by providing the above-mentioned split vehicle door system, a first distance detector 25 for detecting whether there is an obstacle on the movement path of the first vehicle door 21 is provided on the first vehicle door 21, and a second distance detector 15 for detecting whether there is an obstacle on the movement path of the second vehicle door 11 is provided on the second vehicle door 11. If there is an obstacle, the first control unit 24 and the second control unit 14 can automatically adjust the first vehicle door 21 or the second vehicle door 11 to stop moving according to the corresponding vehicle door obstacle signals detected by the corresponding distance detectors, thereby effectively avoiding the collision between the first vehicle door 21 or the second vehicle door 11 and the obstacle, and there is no need for the first control unit 24 and the second control unit 14 to exchange the position information of the first vehicle door 21 and the second vehicle door 11, and the independent control of the first vehicle door 21 by the first control unit 24 and the second vehicle door 11 by the second control unit 14 can be realized, making the control logic of the first vehicle door 21 and the second vehicle door 11 simpler.
