Fig. 5 is a schematic flow chart of a vehicle door opening process of a vehicle door control method according to an embodiment of the present invention. Referring to fig. 5, the present invention further provides a method for controlling the vehicle door 120, which is applied to the vehicle door 120, and the method for controlling the vehicle door 120 in the opening process includes:

s100: controlling the locking structure of the vehicle door to open;

s200: controlling movement of a first door panel of the vehicle door;

s300: acquiring the opening duration of a first door plate of a vehicle door;

s400: when the opening duration is equal to the preset duration, controlling a second driving device of the vehicle door to start;

s500: controlling a second door panel of the vehicle door to move so as to open a second opening at the tail of the vehicle;

s600: and controlling the third door plate of the vehicle door to slide so as to open the third opening of the vehicle body.

It should be noted that, in the control method of the vehicle door 120 provided by the present invention, during the opening process of the vehicle door 120, the locking structure 125 is controlled to open first, and then the first door panel 121 of the vehicle door 120 is controlled to move, so as to open the first opening 111. Then, the second door panel 122 of the vehicle door 120 is controlled to move to open the second opening 112; subsequently, the third door panel 123 of the vehicle door 120 is controlled to slide to open the third opening 113 of the vehicle body 100. The control method of the vehicle door 120 provided by the invention is applied to the vehicle door 120, so that the door opening process is faster, and the technical effect of reducing the requirement of the vehicle door 120 on a larger space in the opening process is achieved.

It should be understood that the opening sequence of the first door panel 121, the second door panel 122 and the third door panel 123 is not limited herein, and in other embodiments, the second door panel 122 located on the upper side of the rear 110 may be opened first, and then the first door panel 121 located on the lower side of the rear 110 and the third door panel 123 adjacent to the rear 110 may be opened according to specific requirements of a user.

It should be noted that, the preset time period includes a time period of moving the first door panel 121 of the vehicle door 120 to be away from the moving track of the second door panel 122 of the vehicle door 120, that is, the first door panel 121 can be effectively prevented from interfering with the rotation of the second door panel 122.

For example, the specific value of the preset time period may be set to 1 second, 2 seconds, 3 seconds, or the like, depending on the factor of the operation speed of the first door panel 121.

It is understood that the specific value of the preset time period is not limited, and in other specific embodiments, the preset time period may also be set to 0.8 second, 1.2 seconds, etc. according to the actual requirement of the user.

That is, the first door panel 121 moves to the running track of the second door panel 122 away from the vehicle door 120 within the preset time period.

It can be understood that, in the present embodiment, the first door panel 121 is opened first, based on the fact that in the present embodiment, the latch tongue of the locking structure 125 is disposed at the top end of the first door panel 121, and the lock slot of the locking structure 125 is disposed at the bottom end of the second door panel 122.

Further, in order to further save the opening time of the vehicle door 120, in the embodiment, when the first door panel 121 moves to a running track of the second door panel 122 away from the vehicle door 120, that is, when the first door panel 121 does not affect the turnover of the second door panel 122, the second driving device is immediately started to drive the second door panel 122 to move. Compared with the method of completely opening the first opening 111 and then driving the second door panel 122, the method saves the door opening time and enables the door 120 to be opened more quickly.

It should be noted that, in other embodiments, when only the second door panel 122 needs to be opened, the first opening 111 does not need to be opened completely, and the first door panel 121 may be driven to a preset angle, that is, when the first door panel 121 moves to a running track of the second door panel 122 away from the vehicle door 120, the first driving device 124 does not need to be continuously driven, and only the second driving device may be controlled to open the second door panel 122. If the third door panel 123 needs to be opened, the third driving device is continuously driven, so as to drive the third door panel 123 to slide. So set up, can be so that door 120's opening process, it is more nimble, laminating user's demand.

Fig. 6 is a schematic flow chart of a vehicle door closing process of a vehicle door control method according to an embodiment of the present invention. Referring to FIG. 6, in an alternative exemplary embodiment, during closing of the vehicle door 120, the control method further includes:

s110: controlling a third door panel of the vehicle door to slide so as to close the third opening;

s210: controlling a second door panel of the vehicle door to move to close the second opening;

s310: controlling a first door panel of the vehicle door to move so as to close the first opening;

s410: and controlling the locking of the locking structure of the vehicle door.

Specifically, in the present embodiment, in the process of closing the vehicle door 120, the third opening 113 is closed first, the third door panel 123 slides to the preset position, and then the second driving device drives the second door panel 122 to turn over to close the second opening 112, between the positions where the lock tongue and the lock groove of the locking structure 125 are disposed and the position relationship between the third door panel 123 and the second door panel 122; then, the first door panel 121 is driven to turn over by the first driving device 124 to close the first opening 111, and then, the locking structure 125 of the vehicle door 120 is controlled to be locked. With such an arrangement, the lock tongue disposed on the first door panel 121 can be easily inserted into the lock groove of the second door panel 122.
