[0067] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0068] Refer to the following Figures 1 to 8 The vehicle door 100 according to the embodiment of the present application is described. In the following description of the present application specification, the directions or positional relationships indicated by "up", "down", "front", "rear", "left" and "right" can be understood with reference to the directions or positional relationships of the vehicle (or vehicle body). For example, the front-to-back direction can be the X-axis direction of the vehicle, the left-to-right direction can be the Y-axis direction of the vehicle, and the up-down direction can be the Z-axis direction of the vehicle.

[0069] The vehicle door 100 of the embodiment of the present application is installed on a vehicle body, the top of the vehicle body has a top door opening 201 , the side of the vehicle body has a side door opening 202 , and the top door opening 201 is connected to the side door opening 202 .

[0070] like Figures 1 to 3 As shown, the vehicle door 100 includes a top door body 10 and a side door body 20. The top door body 10 is rotatably disposed on the top of the vehicle body to open and close the top door opening 201, and the side door body 20 is slidably disposed on the side of the vehicle body to open and close the side door opening 202. The side of the vehicle body is provided with at least one slide rail 50, and the side door body is provided with a sliding matching portion 51 that is slidably matched with the at least one slide rail 50.

[0071] Specifically, the slide rail 50 extends along the sliding direction of the side door body 20, for example, it can extend along the front-rear direction of the vehicle body. The inner surface of the side door body 20 is provided with at least one sliding matching portion 51 respectively matching with at least one slide rail 50. When the side door body 20 slides relative to the vehicle body, the sliding matching portion 51 slides relative to the slide rail 50.

[0072] In one embodiment, the slide rail 50 is multiple and includes a first slide rail 501, a second slide rail 502 and a third slide rail 503. The first slide rail 501, the second slide rail 502 and the third slide rail 503 are arranged at intervals in the height direction of the vehicle body. Specifically, the first slide rail 501 is arranged at the rear side of the side door hole 202 and adjacent to the top of the vehicle body, the second slide rail 502 is arranged at the rear side of the side door hole 202 and below the first slide rail 501, and the third slide rail 503 is arranged at the lower side of the side door hole 202. The side door body 20 is provided with a first sliding fitting portion 511, a second sliding fitting portion 512 and a third sliding fitting portion 513 that form a sliding fit with the first slide rail 501, the second slide rail 502 and the third slide rail 503 respectively. Among them, the first sliding fitting portion 511, the second sliding fitting portion 512 and the third sliding fitting portion 513 can be rollers respectively.

[0073] In the embodiment of the present application, the top door body 10 and the side door body 20 can move independently. For example, either the top door body 10 or the side door body 20 can be opened independently and the other can be in a closed position, or the top door body 10 and the side door body 20 can be opened together. The rotation axis of the top door body can be set at the edge of the top door opening 201 away from the side door opening 202, so that when the top door body and the side door body are both opened, the top door opening 201 and the side door opening 202 are avoided together, so that the connected top door opening 201 and the side door opening 202 form an integral opening area, which is convenient for the driver and passengers to get on and off the vehicle.

[0074] According to the vehicle door 100 of the embodiment of the present application, by setting the top door body 10 and the side door body 20 to open and close the top door opening 201 and the side door opening 202 of the vehicle body respectively, and the top door body 10 rotates relative to the vehicle body and the side door body 20 slides relative to the vehicle body, thereby realizing a special combined opening and closing mode of the top door body 10 and the side door body 20, for example, the side door body 20 is opened alone and the top door body 10 is closed, or the side door body 20 and the top door body 10 are opened at the same time, so as to meet the different use needs of users. Moreover, when the top door body 10 and the side door body 20 are opened at the same time, not only can the basic needs of passengers entering and exiting the interior of the car be met, but also the convenience of passengers entering and exiting the car is improved through the open space of the top door opening. Secondly, by setting at least one slide rail 50 on the vehicle body and setting a sliding matching part 51 that slides with at least one slide rail 50 on the side door body, the movement stability and reliability of the side door body 20 on the vehicle body are improved.

[0075] In one embodiment, the two opposite inner edges of the top door opening 201 in the front-to-back direction are respectively provided with a first locking member 33, and the front side edge and the rear side edge of the top door body 10 are respectively provided with a first locking mating member, and when the top door body 10 is in a closed position, the first locking mating member forms a locking fit with the corresponding first locking member 33.

[0076] It should be noted that in the embodiment of the present application, there is no limitation on the specific structure and matching form of the first locking member 33 and the first locking matching member, as long as the locking matching between the first locking member 33 and the first locking matching member can be achieved.

[0077] With such arrangement, when the top door body 10 is in the closed state, the top door body 10 can be locked through the locking cooperation between the two first locking fittings on the top door body 10 and the two first positions on the vehicle body, thereby improving the stability of the top door body 10 in the closed state.

[0078] In one embodiment, the top door body 10 is provided with an arc guide rail 11, and the side door body 20 is provided with a sliding portion 21; wherein, when the top door body 10 is in a closed state, the sliding portion 21 forms a sliding fit with the arc guide rail 11 during the sliding process of the side door body 20.

[0079] For example, the extension direction of the rotation axis of the top door body 10 can be arranged parallel to the X-axis direction of the vehicle, so that the top door body 10 rotates in a plane perpendicular to the X-axis direction of the vehicle. When the top door body 10 is in the closed position, the top door body 10 is flush with the upper surface of the vehicle body, so that the top door body 10 closes the top door opening 201 of the vehicle body. When the top door body 10 is in the open position, the top door body 10 forms a certain angle with the upper surface of the vehicle body, and the angle can be 60 degrees to 90 degrees, so that the top door body 10 opens the top door opening 201 of the vehicle body.

[0080] The sliding direction of the side door body 20 relative to the vehicle body can be arranged parallel to the X-axis direction of the vehicle, so that the side door body 20 slides in the front-to-back direction relative to the vehicle body. When the side door body 20 is in the closed position, the side door body 20 is located at the side of the vehicle body and is arranged opposite to the side door opening 202, so that the side door body 20 closes the side door opening 202. When the side door body 20 is in the open position, the side door body 20 is located at the side of the vehicle body and at the rear side of the side door opening 202, so that the side door body 20 opens the side door opening 202. The opening direction of the side door body 20 is the sliding direction from front to back, and the closing direction of the side door body 20 is the sliding direction from back to front.

[0081] It can be understood that the top door opening 201 is connected to the side door opening 202, which means that the outer edge of the top door opening 201 coincides with the upper edge of the side door opening 202, so that the top door opening 201 and the side door opening 202 form a complete opening area on the vehicle body. In particular, when the top door body 10 and the side door body 20 are both in the closed position, the outer edge of the top door body 10 is adjacent to the upper edge of the side door body 20, so that the top door body 10 and the side door body 20 jointly close the top door opening 201 and the side door opening 202.

[0082] For example, the arc-shaped guide rail 11 can be provided on the inner surface of the top door body 10 and extend in an arc-shaped direction. The inner surface refers to the surface of the top door body 10 facing the inner side of the vehicle body. The sliding portion 21 can be provided on the top of the side door body 20, and the sliding portion 21 is suitable for forming a sliding fit with the arc-shaped guide rail 11, and the sliding portion 21 is suitable for sliding in the arc-shaped guide rail 11 along the sliding direction of the side door body 20.

[0083] It can be understood that when the sliding part 21 and the arc guide rail 11 form a sliding fit, the side door body 20 is in the closed position, and only when the sliding part 21 and the arc guide rail 11 are disengaged, that is, the two are released from fit, the side door body 20 can rotate from the closed position to the open position.

[0084] In one example, during the sliding stroke of the side door body 20 from the closed position to the open position, the sliding portion 21 and the arc-shaped guide rail 11 are always in sliding cooperation, and only when the side door body 20 slides to the closed position, the sliding portion 21 is disengaged from the arc-shaped guide rail 11. In other words, when both the side door body 20 and the top door body 10 are in the closed state, the top door body 10 remains in the closed state during the opening process of the side door body 20, and the top door body 10 can be opened only when the side door body 20 moves to the open position.

[0085] In another example, in the stroke of the side door body 20 sliding from the closed position to the open position, the sliding part 21 is only in sliding cooperation with the arc guide rail 11 in a part of the stroke, and when the side door body 20 moves to a preset position between the closed position and the open position, the sliding part 21 is disengaged from the arc guide rail 11, and the top door body 10 is suitable for opening. In other words, when the side door body 20 and the top door body 10 are both in the closed state, the side door body 20 can be opened when the side door body 20 moves to the preset position during the opening process, without waiting for the side door body 20 to be fully opened.

[0086] It should be noted that in the embodiment of the present application, there may be multiple doors 100 installed on the vehicle body. The embodiment of the present application does not specifically limit the number of the doors 100. The number of the doors 100 and their arrangement on the vehicle body may be specifically set according to the type of vehicle.

[0087] In one example, for a single-compartment vehicle, the left and right sides of the vehicle body are provided with side door openings 202, respectively, and the top of the vehicle body is provided with two top door openings 201 connected to the side door openings 202 on the corresponding side. There can be two doors 100 and they are arranged symmetrically about the left and right direction of the vehicle (i.e., the Y-axis direction).

[0088] In another example, for a hatchback vehicle, two side door holes 202 are respectively provided on the left and right sides of the vehicle body, and the two side door holes 202 are arranged at intervals in the front-rear direction of the vehicle (i.e., the X-axis direction). Four top door holes 201 are provided on the top of the vehicle body, and the four top door holes 201 correspond to the two side door holes 202 on both sides of the vehicle body.

[0089] According to the above embodiment, by arranging the arc guide rail 11 on the top door body 10 and arranging the sliding part 21 on the side door body 20, the sliding part 21 cooperates with the arc guide rail 11, and the movement stability of the side door body 20 is improved during the opening or closing process of the side door body 20, and when both the top door body 10 and the side door body 20 are in the closed position, the cooperation between the sliding part 21 and the arc guide rail 11 can play a certain supporting and positioning role for the outer edge of the top door body 10. In addition, by arranging the arc guide rail 11 to extend along the arc direction, the side door body 20 can move along the arc track during the opening and closing process through the sliding cooperation between the sliding part 21 and the arc guide rail 11, so that the side door body 20 is embedded in the side door hole 202 of the vehicle body along the arc track during the closing process, or the side door body 20 slides along the arc to the outside of the vehicle body with the side door hole 202 of the vehicle body during the opening process, thereby playing a certain guiding role for the side door body 20.

[0090] In one embodiment, Figures 1 to 3 As shown, the arc guide rail 11 is arranged on the inner surface of the top door body 10, the arc guide rail 11 is arranged adjacent to the front edge of the top door body 10, and the arc guide rail 11 extends in an arc shape from front to back toward the outer edge of the top door body 10. The outer edge of the top door body 10 refers to the edge of the top door body 10 facing the outside of the vehicle body.

[0091] Exemplarily, a stopper is provided at one end of the arc-shaped guide rail 11 adjacent to the front edge of the top door body 10 to stop the sliding part 21. An opening is provided at one end of the arc-shaped guide rail 11 away from the front edge of the top door body 10 so that the sliding part 21 can slide into or out of the arc-shaped guide rail 11 through the opening. In the direction from back to front, the arc-shaped guide rail 11 gradually extends in an arc shape toward a direction away from the outer edge of the top door body 10.

[0092] With such a configuration, when the side door body 20 slides from the closed position to the open position, i.e., backward, the sliding portion 21 slides backward and gradually outward in the arc-shaped guide rail 11, so that the side door body 20 can slide backward and outward from the closed position embedded in the side door opening 202 to the outside of the vehicle body, so as to realize the opening action of the side door body 20. Correspondingly, when the side door body 20 slides from the open position to the closed position, i.e., forward, the sliding portion 21 slides forward and gradually inward in the arc-shaped guide rail 11, so that the side door body 20 can slide forward and inward from the outside of the vehicle body to the side door opening 202, so as to realize the closing action of the side door body 20.

[0093] In one embodiment, the side door body 20 is suitable for sliding relative to the vehicle body between a closed position and an open position, and there is a preset position between the closed position and the open position. The preset position is the critical position of the vehicle door when the sliding portion 21 slides into or out of the arc guide rail 11.

[0094] like Figure 2 As shown, when the side door body 20 moves from the closed position to the open position, when the side door body 20 moves to the preset position, the sliding part 21 is about to slide out of the arc guide rail 11; and / or, when the side door body 20 moves from the closed position to the open position, when the side door body 20 moves to the preset position, the sliding part 21 is about to slide into the arc guide rail 11. In the process of the side door body 20 sliding from the preset position to the open position, the top door body 10 is suitable for opening.

[0095] The preset position can be understood as the position of the side door body 20 when the sliding portion 21 and the arc-shaped guide rail 11 are about to be separated or about to form a sliding fit during the sliding process of the side door body 20. For example, when the side door body 20 slides from the closed position to the open position, the position of the side door body 20 when the sliding portion 21 slides to the end of the front side edge of the arc-shaped guide rail 11 away from the top door body 10 is the preset position. For another example, when the side door body 20 slides from the open position to the closed position, the position of the side door body 20 when the sliding portion 21 slides to the end of the front side edge of the arc-shaped guide rail 11 away from the top door body 10 is the preset position.

[0096] Furthermore, the length dimension of the arc guide rail 11 in the front-to-rear direction of the vehicle body can be 1 / 3 to 1 / 2 of the length dimension of the side door opening 202, and the preset position of the side door body 20 can specifically be any position between 1 / 3 and 1 / 2 of the maximum stroke when the side door body 20 is opened. The embodiment of the present application does not limit the length dimension of the arc guide rail 11 and the specific position of the preset position, and technical personnel in this field can make specific settings based on actual conditions.

[0097] Through the above embodiment, during the opening process of the side door body 20, the top door body 10 can perform the opening action without waiting for the side door body 20 to be fully opened, thereby realizing the combined action of the top door body 10 and the side door body 20 being opened in conjunction.

[0098] In one embodiment, Figure 6 and Figure 7 As shown, the top door body 10 is provided with an interior decoration component, which is arranged on the inner surface of the top door body 10 and adjacent to the outer edge of the top door body 10. The interior decoration component includes a fixed part 41 and a movable part 42, the fixed part 41 is fixedly connected to the inner surface of the top door body 10, the movable part 42 is rotatably connected to the fixed part 41, and the movable part 42 is suitable for forming an overlapped fit with the inner surface of the side door body 20. In the case where the movable part 42 forms an overlapped fit with the inner surface of the side door body 20, the top door body 10 cannot be rotated from the closed position to the open position.

[0099] Exemplarily, the movable member 42 is rotatably connected to the fixed member 41 via a rotating shaft, and the rotating shaft is suitable for driving the movable member 42 to rotate relative to the fixed member 41 between a first position and a second position under the drive of a motor. Wherein, when the top door body 10 is in the closed position, when the movable member 42 is in the first position, the movable member 42 is suitable for forming an overlap fit with the inner surface of the side door body 20, and the movable member 42 and the fixed member 41 form a receiving space at the junction with the top door body 10 and the side door body 20, and the arc guide rail 11 and the sliding part 21 are covered by the movable member 42 and the fixed member 41 in the receiving space to prevent the arc guide rail 11 and the sliding part 21 from being exposed to the internal space of the vehicle body. When the movable member 42 is in the second position, the movable member 42 is disengaged from the inner surface of the side door body 20, so that the top door body 10 can rotate from the closed position to the open position.

[0100] Further, when both the top door body 10 and the side door body 20 are in the closed position, the movable member 42 is in the first position. When the sliding portion 21 slides to the end of the arc-shaped guide rail 11 away from the front edge of the top door body 10 during the opening process of the side door body 20, the movable member 42 rotates to the second position, so that the movable member 42 is separated from the inner surface of the side door body 20, so that the side door body 20 can be opened from the closed position.

[0101] In one embodiment, Figure 4 and Figure 5 As shown, the two inner edges of the side door hole 202 opposite to each other in the front-to-back direction are respectively provided with second locking members 31, and the front and rear sides of the side door body 20 are respectively provided with second locking fitting members 32. When the side door body 20 is in the closed position, the second locking fitting member 32 at the front side forms a locking fit with the second locking member 31 at the front side; when the side door body 20 is in the open position, the second locking fitting member 32 at the rear side forms a locking fit with the second locking member 31 at the rear side.

[0102] Exemplarily, the two second locking members 31 are respectively arranged adjacent to the top of the vehicle body, wherein the second locking member 31 located on the front side is arranged adjacent to the front end of the arc guide rail 11. The sliding portion 21 includes a seat body, a roller and two second locking fittings 32. The roller is rotatably arranged on the seat body, and is used to form a rolling fit with the arc guide rail 11. The two second locking fittings 32 are respectively arranged on the seat body, and are located on the front and rear sides of the roller, wherein the second locking fitting 32 located on the front side is suitable for forming a locking fit with the second locking member 31 located on the front side when the side door body 20 is in a closed position, and the second locking fitting 32 located on the rear side is suitable for forming a locking fit with the second locking member 31 located on the rear side when the side door body 20 is in an open position.

[0103] It should be noted that in the embodiment of the present application, there is no limitation on the specific structure and matching form of the second locking member 31 and the second locking matching member 32, as long as the locking matching of the second locking member 31 and the second locking matching member 32 can be achieved.

[0104] According to the above embodiment, the side door body 20 can be locked when the side door body 20 is in the open position or the closed position, and the two second locking fittings 32 are integrated into the sliding portion 21 of the side door body 20, thereby reducing the structural complexity of the side door body 20 and improving the structural integration of the side door body 20.

[0105] In one embodiment, Figure 8 As shown, the inner edges of the top door opening 201 and the side door opening 202 are provided with a first sealing member 61 , and the side edges of the top door body 10 and the side door body 20 are respectively provided with a first sealing member 62 that seals with the first sealing member 61 .

[0106] Exemplarily, the first sealing member 61 may be in the shape of a strip, and the first sealing member 61 is disposed at the inner edge of the top door opening 201 and the side door opening 202. A sealing groove is disposed on the side of the first sealing member 61 away from the inner edge of the top door opening 201 or the side door opening 202, and the opening direction of the sealing groove is disposed toward the inner side of the top door opening 201 or the side door opening 202. The first sealing fitting member 62 is disposed around the outer edge of the top door body 10 and the side door body 20, and the first sealing fitting member 62 is provided with a sealing protrusion. When the top door body 10 or the side door body 20 is in a closed state, the sealing protrusion of the fitting member of the first sealing member 61 is embedded in the sealing groove of the first sealing member 61, thereby forming a sealing fit.

[0107] The present embodiment does not specifically limit the materials of the first sealing member 61 and the first sealing fitting member 62. For example, the first sealing member 61 and the first sealing fitting member 62 can both be made of PVC (polyvinyl chloride) material.

[0108] In one embodiment, one of the outer edge of the top door body 10 and the upper edge of the side door body 20 is provided with a second sealing member 63, and the other is provided with a second sealing member. When both the top door body 10 and the side door body 20 are in the closed position, the second sealing member 63 and the second sealing member form a sealing fit.

[0109] Exemplarily, the second sealing member 63 is disposed on the lower surface of the top door body 10, and the second sealing member 63 is disposed adjacent to the outer edge of the top door body 10. The second sealing fitting member is disposed on the upper side of the side door body 20. When both the top door body 10 and the side door body 20 are in the closed position, the second sealing fitting member and the second sealing member 63 form a sealing fit.

[0110] Furthermore, the specific form of the sealing cooperation between the second sealing fitting member and the second sealing member 63 may be the same as or similar to the sealing cooperation between the first sealing member 61 and the first sealing fitting member 62 , and will not be described in detail herein.

[0111] According to another aspect of the embodiments of the present application, a control method for a vehicle door is also provided, which is applied to the vehicle door of any of the above-mentioned embodiments of the present application, and is specifically used to control the coordinated opening of the top door body and the side door body of the vehicle door.

[0112] like Fig. 9 As shown, the door control method includes the following steps:

[0113] S101: In response to a door linkage opening request, determining whether the top door body is in a top door closing position;

[0114] S102: If the top door body is not in the top door closed position, determine whether the opening corresponding to the current position of the side door body is greater than or equal to a first opening threshold; wherein the first opening threshold is the opening corresponding to the critical position of the side door body when the sliding portion of the side door body slides out of the arc guide rail of the top door body;

[0115] S103: If the opening degree corresponding to the current position of the side door body is greater than or equal to the first opening degree threshold, the top door body is controlled to open, and the side door body is controlled to open.

[0116] In the embodiment of the present application, the top door closed position refers to a position in which the top door body is in a completely closed position, that is, when the top door body is in the top door closed position, the top door body completely closes the top door opening.

[0117] Exemplarily, the opening corresponding to the current position of the side door body can be understood as the degree of opening of the side door body. For example, the maximum stroke of the side door body from the side door closed position to the open position is S0, and the stroke of the side door body from the side door closed position to the current position is S1, then the opening corresponding to the current position of the side door body is the ratio of S1 to S0. It can be understood that the larger the opening, the greater the degree of opening of the side door body, and the smaller the opening, the smaller the degree of opening of the side door body.

[0118] The first opening threshold is the opening corresponding to when the side door body is in a critical position, and the critical position is the critical position of the door when the sliding part slides into or out of the curved guide rail. In other words, when the opening of the side door body is equal to the opening threshold, the side door body is in a critical position, and the sliding part is disengaged from the curved guide rail, so that the top door and the side door body can move independently without interfering with each other. Furthermore, when the opening of the side door body is greater than the opening threshold, the sliding part is necessarily disengaged from the curved guide rail, so that the top door and the side door body can also move independently without interfering with each other.

[0119] According to the vehicle door control method of the embodiment of the present application, by judging whether the opening corresponding to the current position of the side door body is greater than or equal to the first opening threshold, it is avoided that the top door body or the side door body is forcibly opened when the arc guide rail and the sliding part form a sliding fit, causing interference between the two, thereby ensuring that the top door body and the side door body are controlled to open when the arc guide rail and the sliding part are out of fit, thereby ensuring the reliability of the linkage opening of the top door body and the side door body.

[0120] In one embodiment, the control method further comprises the following steps:

[0121] If the opening degree corresponding to the current position of the side door body is less than the first opening degree threshold, the side door body is controlled to move to a target position, and the opening degree corresponding to the target position is greater than or equal to the first opening degree threshold.

[0122] It should be noted that, when the opening corresponding to the current position of the side door body is less than the first opening threshold, the arc guide rail on the top door body cooperates with the sliding part on the side door body, resulting in the top door body being unable to open smoothly due to the interference of the side door body. Therefore, it is necessary to first control the opening of the side door body so that the side door body moves to the target position, so that the arc guide rail on the top door body is disengaged from the sliding part on the side door body, so as to contact the interference of the side door body on the top door body, thereby ensuring that the top door body can be opened smoothly.

[0123] In one embodiment, controlling the top door to open in step S103 may specifically include the following steps:

[0124] During the opening process of the top door body, determining whether a first stop opening condition is met; wherein the first stop opening condition includes the presence of an obstacle within a preset distance range of the top door body;

[0125] If the first stop opening condition is met, the top door body is controlled to stop opening; or, if the first stop opening condition is not met, the top door body is controlled to move to the first opening position.

[0126] For example, during the opening process of the top door body, it can be determined multiple times whether the top door body meets the first stop opening condition. For example, it can be determined once every preset time interval whether the top door body meets the first stop opening condition, wherein the preset time interval can be any time interval, specifically 0.2 seconds, and the embodiment of the present application does not specifically limit this.

[0127] The preset distance range of the top door body can be set accordingly according to the movement trajectory of the top door body from the top door closing position to the top door opening position. As long as there is an obstacle on the movement trajectory of the top door body, it can be determined that the first stop opening condition is met.

[0128] Among them, any detection device can be used to detect obstacles, including but not limited to laser radar, any form of sensor, etc., and the embodiments of the present application do not specifically limit this.

[0129] Through the above implementation, it is possible to avoid the top door body colliding with obstacles during the opening process due to obstacles near the top door body, thereby improving the reliability and safety of the top door body opening.

[0130] In one embodiment, controlling the side door to open in step S103 may specifically include the following steps:

[0131] During the opening process of the side door body, determining whether a second stop opening condition is met; wherein the second stop opening condition includes the presence of an obstacle within a first preset distance range of the side door body, and / or the presence of a target object moving toward the side door body within a second preset distance range of the side door body;

[0132] If the second stop opening condition is met, the side door body is controlled to stop opening; and if the second stop opening condition is not met, the side door body is controlled to move to the second opening position.

[0133] For example, during the opening process of the side door body, it can be determined multiple times whether the side door body meets the second stop opening condition. For example, it can be determined once every preset time interval whether the side door body meets the second stop opening condition, wherein the preset time interval can be any time interval, specifically 0.2 seconds, and the present embodiment of the application does not specifically limit this.

[0134] The first preset distance range of the side door body can be set accordingly according to the movement trajectory of the side door body from the side door closed position to the open position. As long as there is an obstacle within the movement trajectory of the side door body, it can be determined that the second stop opening condition is met. The second preset distance range of the side door body can be a set distance range in the lateral direction of the side door body, and the target object can be any moving object, such as a motor vehicle, a non-motor vehicle, a pedestrian, or any other moving object. Among them, any detection device can be used for the detection of obstacles and targets, including but not limited to laser radar, any form of sensor, etc., and the embodiments of the present application do not specifically limit this.

[0135] Through the above-mentioned implementation, it is possible to avoid the side door body colliding with obstacles during the opening process or the user colliding with the target object after getting off the vehicle due to obstacles near the side door body or objects moving towards the side door body, thereby improving the reliability of the side door body opening, improving the safety of the user, and reducing the probability of accidents.

[0136] In one implementation, after step S101, the control method may further include:

[0137] If the top door body is in the top door closed position, determine whether there is an obstacle within the preset distance range of the side door body;

[0138] If there is an obstacle within the preset distance range of the side door body, the side door body is controlled to maintain the current position; or, if there is no obstacle within the preset distance range of the side door body, the side door body is controlled to move to the target position, and the opening corresponding to the target position is greater than or equal to the first opening threshold.

[0139] It can be understood that when the top door body is in the top door closed position and there are no obstacles within the preset distance range of the side door body, after controlling the side door body to move to the target position, the arc guide rail of the top door body disengages from the sliding part of the side door body. At this time, the top door body meets the opening conditions and the top door body can be controlled to open.

[0140] Refer to the following Fig.10 The detailed steps of the control method for vehicle doors in the embodiment of the present application in the process of controlling the linked opening of vehicle doors are described with a specific example.

[0141] like Fig.10 As shown, after receiving the door linkage opening request, the control method of the embodiment of the present application specifically includes:

[0142] (1) Determine whether the top door body is in the top door closed position.

[0143] (2) When the top door body is in the top door closed position, determine whether there is an obstacle near the top door body; if there is an obstacle near the top door body, control the top door body to maintain the current closed position; if there is no obstacle near the top door body, control the side door body to open.

[0144] (3) when the top door body is not in the closed position, determining whether the side door body has reached the target position; when the side door body has not reached the target position, controlling the side door body to open and move to the target position; when the side door body has reached the target position, controlling the top door body and the side door body to open respectively;

[0145] The specific process of controlling the opening of the top door body is as follows: judging whether there is an obstacle near the top door body; if there is an obstacle near the top door body, controlling the top door body to stop opening; if there is no obstacle near the top door body, judging whether the top door body has moved to the top door opening position, if it has not moved to the top door opening position, controlling the top door body to continue opening, and if it has moved to the top door opening position, controlling the top door body to stop opening;

[0146] Among them, the specific process of controlling the opening of the side door body is as follows: determine whether there is an obstacle near the side door body, if there is an obstacle, control the side door body to stop opening, if there is no obstacle, determine whether the side door body moves to the side door opening position; and, determine whether there is a dangerous object approaching the side door body, if there is a dangerous object approaching, control the side door body to stop opening, if there is no dangerous object approaching, determine whether the side door body moves to the side door opening position; when the side door body moves to the side door opening position, control the side door body to stop opening.

[0147] According to another aspect of the embodiments of the present application, a control method for a vehicle door is also provided, which is applied to the vehicle door of any of the above-mentioned embodiments of the present application, and is specifically used to control the coordinated closing of the top door body and the side door body of the vehicle door.

[0148] like Fig.11 As shown, the control method includes the following steps:

[0149] S201: In response to a door linkage closing request, determining whether the top door body is in a top door closing position;

[0150] S202: If the top door body is not in the top door closing position, determine whether the opening corresponding to the current position of the side door body is greater than or equal to a first opening threshold; wherein the first opening threshold is the opening corresponding to the critical position of the side door body when the sliding portion of the side door body slides out of the arc guide rail of the top door body; if the opening corresponding to the current position of the side door body is greater than or equal to the first opening threshold, control the top door body to close;

[0151] S203: If the top door body is in the top door closing position, the side door body is controlled to close.

[0152] In the embodiment of the present application, the top door closed position refers to the top door body being in a fully closed position, that is, when the top door body is in the closed position, the top door body completely closes the top door opening. The side door closed position refers to the side door body being in a fully closed position, that is, when the side door body is in the side door closed position, the side door body completely closes the side door opening.

[0153] Exemplarily, the opening corresponding to the current position of the side door body can be understood as the degree of opening of the side door body. For example, the maximum stroke of the side door body from the side door closed position to the open position is S0, and the stroke of the side door body from the side door closed position to the current position is S1, then the opening corresponding to the current position of the side door body is the ratio of S1 to S0. It can be understood that the larger the opening, the greater the degree of opening of the side door body, and the smaller the opening, the smaller the degree of opening of the side door body.

[0154] The first opening threshold is the opening corresponding to when the side door body is in a critical position, and the critical position is the critical position of the door when the sliding part slides into or out of the curved guide rail. In other words, when the opening of the side door body is equal to the opening threshold, the side door body is in a critical position, and the sliding part is disengaged from the curved guide rail, so that the top door and the side door body can move independently without interfering with each other. Furthermore, when the opening of the side door body is greater than the opening threshold, the sliding part is necessarily disengaged from the curved guide rail, so that the top door and the side door body can also move independently without interfering with each other.

[0155] According to the vehicle door control method of the embodiment of the present application, by judging whether the opening corresponding to the current position of the side door body is greater than or equal to the first opening threshold, it is possible to avoid controlling the top door body to close directly when the opening of the side door body is less than the opening threshold, resulting in the top door body being unable to close due to interference between the arc guide rail and the sliding part, thereby ensuring the reliability of the linkage closing of the top door body and the side door body.

[0156] In one embodiment, after determining whether the opening corresponding to the current position of the side door body is greater than or equal to the first opening threshold, the control method further includes:

[0157] If the opening corresponding to the current position of the side door body is less than the first opening threshold, the side door body is controlled to move to the target position, which is any position whose corresponding opening is greater than or equal to the first opening threshold; and the top door body is controlled to close.

[0158] It should be noted that, when the opening corresponding to the current position of the side door body is less than the first opening threshold, that is, during the closing process of the top door body, the arc guide rail on the top door body will interfere with the sliding part on the side door body, resulting in the top door body being unable to close smoothly. Therefore, it is necessary to control the opening of the side door body so that the side door body moves to the target position, thereby avoiding the top door body being unable to close due to the interference between the arc guide rail and the sliding part during the closing process of the top door body. After controlling the top door body to move to the top door closing position, the side door body can be controlled to move to the side door closing position, and during the closing process of the side door body, the sliding part slides into the arc guide rail to form a sliding fit. In addition, when the opening corresponding to the current position of the side door body meets the opening threshold condition, the side door body can be controlled to maintain the current position.

[0159] In one embodiment, controlling the top door to close includes:

[0160] During the closing process of the top door body, determining whether a first stop closing condition is met; wherein the first stop closing condition includes the presence of an obstacle within a preset distance range of the top door body;

[0161] If the first stop closing condition is met, the top door body is controlled to stop closing; or, if the first stop closing condition is not met, the top door body is controlled to move to the top door closing position.

[0162] For example, during the closing process of the top door body, it can be determined multiple times whether the top door body meets the first stop closing condition. For example, it can be determined once every preset time interval whether the top door body meets the first stop closing condition, wherein the preset time interval can be any time interval, specifically 0.2 seconds, and the embodiment of the present application does not specifically limit this.

[0163] The preset distance range of the top door body can be set accordingly according to the movement trajectory of the top door body from the open position to the first closed position. As long as there is an obstacle on the movement trajectory of the top door body, it can be determined that the first stop closing condition is met.

[0164] Among them, any detection device can be used to detect obstacles, including but not limited to laser radar, any form of sensor, etc., and the embodiments of the present application do not specifically limit this.

[0165] Through the above implementation, it is possible to avoid the top door body colliding with the obstacle during the closing process due to the presence of an obstacle near the top door body, thereby improving the reliability and safety of the top door body closing.

[0166] In one embodiment, controlling the side door to close includes:

[0167] During the closing process of the side door body, determining whether a second stop closing condition is met; wherein the second stop closing condition includes the presence of an obstacle within a first preset distance range of the side door body, and / or the presence of a target object moving toward the side door body within a second preset distance range of the side door body;

[0168] If the second stop closing condition is met, the side door body is controlled to stop closing; or, if the second stop closing condition is not met, the side door body is controlled to move to the side door closing position.

[0169] For example, during the closing process of the side door body, it can be determined multiple times whether the side door body meets the second stop closing condition. For example, it can be determined once every preset time interval whether the side door body meets the second stop closing condition, wherein the preset time interval can be any time interval, specifically 0.2 seconds, and the present embodiment of the application does not specifically limit this.

[0170] The first preset distance range of the side door body can be set accordingly according to the movement trajectory of the side door body from the open position to the second closed position. As long as there is an obstacle within the movement trajectory of the side door body, it can be determined that the first stop closing condition is met. The second preset distance range of the side door body can be a set distance range in the lateral direction of the side door body, and the target object can be any moving object, such as any moving object such as a motor vehicle, a non-motor vehicle, a pedestrian, etc.

[0171] Among them, any detection device can be used to detect obstacles and targets, including but not limited to laser radar, any form of sensor, etc., and the embodiments of the present application do not make specific limitations on this.

[0172] Through the above-mentioned implementation, it is possible to avoid the side door body colliding with obstacles or targets during the closing process due to the presence of obstacles near the side door body or objects moving towards the side door body, thereby improving the reliability of the side door body closing, improving the safety of the user, and reducing the probability of accidents.

[0173] Refer to the following Fig.12 The detailed steps of the control method for vehicle doors in the embodiment of the present application in the process of controlling the linked closing of vehicle doors are described with a specific example.

[0174] like Fig.12 As shown, after receiving the door linkage closing request, the control method of the embodiment of the present application specifically includes:

[0175] (1) Determine whether the top door body is in the top door closed position.

[0176] (2) When the top door is in the closed position, the side door is controlled to close;
