For example, a motor driving mechanism is arranged between the movable middle island 1 and the track assembly 2, a middle island motor of the motor driving mechanism is controlled by a middle island controller, and the movable middle island 1 is driven to move back and forth along the track assembly 2 by the motor driving mechanism.
As a preferred example, when the movable center island 1 is located at the first position, the movable center island 1 is located at the stroke front dead center. When the movable center island 1 is located at the second position, the movable center island 1 is located at the stroke rear dead center.
In some embodiments, the two second row seats 4 are zero gravity seats. The zero gravity seat is applied to the second row of the vehicle, so that the comfort requirement of a user can be better met.
In some embodiments, the two second row seats 4 are longitudinally and laterally movable vehicle seats. The second-row seats 4 are movable longitudinally and laterally, so that the positions of the second-row seats 4 are more flexible and changeable, and the restriction of the arrangement space in the vehicle to the second-row seats 4 can be reduced. On the one hand, the cabin of the vehicle is more flexible and changeable, and the diversified demands of users are better met, and on the other hand, a foundation is provided for adopting the zero-gravity seat as the second row seat 4 of the vehicle. As a preferred example, the two second row seats 4 are zero gravity seats that can be moved longitudinally and laterally.
As a specific example, the second row seats 4 are mounted on a lateral seat rail mounted on a longitudinal seat rail mounted on the floor of the vehicle, the second row seats 4 are driven to move laterally along the lateral seat rail by a traversing drive motor connected to the seat controller, and the second row seats 4 and the lateral seat rail are driven to move longitudinally along the longitudinal seat rail by a longitudinal drive motor connected to the seat controller.
In some embodiments, the rear of the movable center island 1 is provided with a control panel 13. The control panel 13 is used for displaying information and inputting information for a user, and the control panel 13 can be used as an interaction window between a second-row passenger and the vehicle, so that convenience is provided for the second-row user to control functions of the vehicle-mounted module. For example, the moving direction and moving distance of the movable center island 1 may be controlled by the control panel 13. In particular implementations, the control panel 13 may be configured as a touch screen.
As a specific example, as shown in fig. 6 and 7, the control panel 13 of the movable middle island 1 is provided with an adjusting key, when the occupant clicks the adjusting key on the control panel 13, the movable middle island 1 can be controlled to slide back and forth, and more convenient service can be provided for the second-row occupant and the third-row occupant.
In some embodiments, the front of the movable center island 1 is provided with a front cup holder 15 and the rear of the movable center island 1 is provided with a rear cup holder 16. The provision of the rear cup holder 16 for use by the second row of occupants helps to enhance the user's vehicle experience.

In some embodiments, a charging port 17 is provided on the movable center island 1. The charging port 17 is arranged to help promote the user's vehicle experience. In specific implementation, the charging port 17 may be a Type C charging port.
In some embodiments, the vehicle further comprises a third row of seats 5 located behind the second row of seats 4. The third row of seats 5 is arranged so that the vehicle can take more passengers, and the third row of seats 5 and the second row of seats 4 can form a bed so as to meet the requirements of resting and sleeping in the vehicle of a user.
In the specific implementation, the backrest of the front row seat 3 and the backrest of the third row seat 5 can be electric angle adjusters, and the electric angle adjusters have the characteristic of convenient control. The adjustment control of the front row seat 3, the second row seat 4, the third row seat 5, and the movable center island 1 can be realized by an on-vehicle controller, for example, a vehicle body domain controller, a seat controller, and a center island controller.
In some embodiments, the left and right sides of the second row seat 4 are provided with armrests 6, and the armrests 6 can provide hand support for the passengers, thereby improving comfort.
In some embodiments, as shown in fig. 8 and 12, the present invention also proposes a control method for controlling the vehicle according to any one of the above, the two second-row seats 4 being longitudinally and laterally movable vehicle seats, the control method comprising the step of controlling the two second-row seats 4 to move laterally inward to reduce the spacing between the two second-row seats 4 after determining that the user has an intention to reduce the spacing between the two second-row seats 4. By reducing the spacing between the two second row seats 4, the two second row occupants are brought closer together, meeting the close range ride requirements between some users.
For example, as shown in fig. 2, when the user puts down the ceiling screen 8 of the vehicle to view, the user can adjust the close double-seat control keys 11 on the guard plates of the seats to control the two second-row seats 4 to approach each other so as to realize two-three-row viewing. As shown in fig. 4, the overhead screen 8 may be controlled by overhead screen control keys 10 on the armrest 6.
In practice, as shown in fig. 4, it is possible to determine whether the user has an intention to reduce the distance between the two second-row seats 4 by an instruction input by the user. For example, when an instruction is input through the close two-person position control key 11, it is possible to determine that the user has an intention to reduce the distance between the two second-row seats 4.
In some embodiments, to prevent active interference between the movable center island 1 and the second row seats 4, the step of controlling the movable center island 1 to move forward to leave the space between the two second row seats 4 is further included before controlling the two second row seats 4 to move laterally to reduce the space between the two second row seats 4. As a preferred example, the movable center island 1 may be controlled to move forward to the stroke front dead center so that the movable center island 1 leaves the space between the two second-row seats 4.
More specifically, after determining that the user has an intention to reduce the distance between the two second-row seats 4, if the movable middle island 1 is not at the stroke front dead center, the second-row seats 4 are not operated when the user presses the close double-person position control key 11, and a pop-up window is provided on the control panel 13 to prompt "please move the middle island to the forefront position". If the movable center island 1 is located at the stroke front dead center, both the second row seats 4 are moved laterally inward by a reduced Y-distance.
In some embodiments, the present invention also proposes a control method for controlling the vehicle according to any one of the above, wherein the two second-row seats 4 are longitudinally and transversely movable zero-gravity seats, the vehicle further comprises a third-row seat 5 positioned behind the second-row seats 4, and the control method comprises the steps of controlling inward lateral movement of the second-row seats 4, and controlling cushion and backrest adjustment of the second-row seats 4 to a preset zero-gravity position when it is determined that the user has an intention to adjust the second-row seats 4 to the zero-gravity mode, the front-row seats 3 in front of the second-row seats 4 are occupied, the third-row seats 5 behind the second-row seats 4 are unoccupied, and the movable middle island 1 is positioned at a stroke front dead center, as shown in fig. 2;
As shown in fig. 3, when it is determined that the user has an intention to adjust the second row seat 4 to the zero gravity mode, the front row seat 3 in front of the second row seat 4 is not occupied, the third row seat 5 in rear of the second row seat 4 is not occupied, and the movable center island 1 is located at the stroke front dead center, the front row seat 3 is controlled to move forward, the second row seat 4 is controlled to move laterally inward, and the seat cushion, the backrest, and the leg rest of the second row seat 4 are controlled to be adjusted to the preset zero gravity positions.
By adopting the technical scheme, when the front row is occupied, the second row seat 4 is adjusted to a zero gravity mode, the leg support is not automatically adjusted, and the feet of the second row passengers and the backrest of the front row seat 3 can be prevented from being interfered and extruded after the leg support is lifted. The leg rest will continue to remain in the stowed position, at which point the user can adjust the leg rest to a comfortable position by adjusting the leg rest control keys 12 on the seat cover as shown in fig. 5. When the second row of seats 4 are adjusted to the zero gravity mode in the front row of unmanned seats, the leg rest is automatically adjusted along with the cushion and the backrest, so that more comfortable riding experience is provided for a user.
As a specific example, as shown in fig. 2, when a person sits on the front row seat 3, the occupant detection sensor 19 detects a sitting person signal. When the occupant activates the zero gravity control 9 on the armrest 6 of the second row seat 4, the second row seat has no feedback if the third row seat 5 sits. When the passenger triggers the zero gravity control key 9 on the armrest 6 of the second row seat 4, if the third row seat 5 is not sitting on a person, the switch signal is transmitted to the middle island controller of the movable middle island 1, and the middle island controller detects the signal and controls the movable middle island 1 to slide forwards to the stroke front dead point. When the occupant activates the zero gravity control 9 on the armrest 6 of the second row seat 4, the movable center island 1 will not be actuated if the movable center island 1 is already at the travel front dead center at this time. When the occupant activates the zero gravity control 9 on the armrest 6 of the second row seat 4, the second row seat 4 is not deployed if the movable center island 1 position status signal determines that the movable center island 1 has not moved to the travel front dead center. When the passenger triggers the zero gravity control key 9 on the armrest 6 of the second row of seats 4, the third row of seats 5 is not seated, if the movable middle island 1 has reached the front stop point of the stroke, the second row of seats 4 can sequentially slide horizontally, lift the cushion and rotate the backrest to a preset zero gravity angle, but after the leg rest is lifted, the feet of the passenger and the backrest of the front row of seats 3 interfere and squeeze at this time, the leg rest of the second row of seats 4 can keep in a retracted state, and the user can automatically adjust the leg rest to a comfortable position by adjusting the leg rest adjustment control key on the seat guard plate.
As a specific example, as shown in fig. 3, if the third row seat 5 is not sitting and the front row seat 3 is not sitting, when the occupant activates the zero gravity control key 9 on the armrest 6 of the second row seat 4 or the zero gravity control key 9 on the seat side shield, the front row seat 3 is interlocked at this time to control the front row seat 3 to slide to the forefront position, except for the operation in the above example. In this state, the leg rest of the second row seat 4 can be unfolded to the maximum angle to provide better leg support for the occupant and a more comfortable seating experience for the user.
In some embodiments, in order to prevent the occurrence of active interference between the movable center island 1 and the second row seats 4, the present invention also proposes a control method for controlling the vehicle according to any one of the above, the two second row seats 4 being longitudinally and laterally movable vehicle seats, the control method comprising the steps of requesting confirmation of control of the reset of the second row seats 4 from the user upon receipt of an instruction to move the movable center island 1 rearward after the second row seats 4 are laterally moved inward, and controlling the reset of the second row seats 4 upon receipt of an instruction to confirm the control of the reset of the second row seats 4 from the user, and then controlling the movable center island 1 to be moved rearward.
As a specific example, when the second row occupant wants to take a cup in the cup holder of the movable center island 1, or when the third row occupant wants to take an article in the refrigerator 18 of the movable center island 1, or wants to charge the wireless charging device 14 or the charging port 17 on the movable center island 1, the movable center island 1 can be adjusted to move backward. Because the second row seat 4 has a traversing function, after the second row seat 4 traverses, in order to avoid collision between the movable middle island 1 and the second row seat 4, the control panel 13 pops a window to prompt that "the seat has traversed, the middle island cannot be moved, whether the seat needs to be retracted", and if the user clicks "confirm", the second row seat 4 is controlled to slide to the outermost side.
In some embodiments, in order to improve the convenience of getting on and off the vehicle, the invention also provides a control method for controlling the vehicle according to any one of the above, the control method comprising the step of adjusting the movable center island 1 of the vehicle so that a passage for the user to pass through is formed between the movable center island 1 and the instrument panel 7 of the vehicle after determining that the user has an intention to get on from the secondary driving position of the vehicle to get on the driving position or get off from the driving position of the vehicle to get off the secondary driving position. In particular implementations, it may be determined, based on a user's instructions, whether the user has an intention to get in from the passenger location of the vehicle to the driver's seat or get out from the driver's seat to the passenger location.
As a specific example, when the opening space of the door at the main driving side is limited, the movable middle island 1 can be adjusted to move backwards through the display screen, at this time, if the position of the second row of seats 4 is relatively forward, the second row of seats 4 can slide to the final position preferentially, the user is prompted to lift the armrests 6 of the second row of seats 4, then the front row of seats 3 all move backwards to the final position, and the driver can directly move from the interior of the vehicle to the secondary driving position, and get off from the secondary driving side, so that the convenience of getting off is realized.
In some embodiments, in order to prevent the movable center island 1 from interfering with the movement of the armrest 6 of the second row seat 4, the invention also proposes a control method for controlling the vehicle according to any one of the above, the control method comprising the steps of providing the two second row seats 4 with armrests 6, the control method comprising the steps of requesting a confirmation from the user as to whether the armrests 6 of the second row seats 4 are raised upon receipt of an instruction to move the movable center island 1 backward, and controlling the movable center island 1 to move backward upon receipt of an instruction from the user to confirm that the armrests 6 of the second row seats 4 have been raised.
As a specific example, the second row seats 4 are provided with armrests 6, the armrests 6 can be unfolded downwards, the distance between the armrests 6 of the two second row seats 4 is limited, when the armrests 6 are put down, in order to avoid collision with the armrests 6 when the movable middle island 1 moves backwards, a control panel 13 pops a window to prompt that 'please confirm whether the armrests 6 of the second row seats 4 are lifted', and two virtual keys are given to 'confirm' and 'cancel' in the pop window. If the user clicks "confirm", the movable island 1 should continue to move to the target position that the user needs to adjust, and if the user clicks "cancel", the movable island 1 keeps the current position from moving.
In some embodiments, the invention further provides a control method for controlling the vehicle according to any one of the above, wherein the control method comprises the steps of controlling the front seats 3 to move forward after receiving the instruction to enter the first preset mode, controlling the movable middle island 1 to move forward, controlling the rear seats 4 to move backward, and controlling the back of the two second seats 4 to fall backward. The cushions of the two second row seats 4 and the third row seat 5 may constitute a bed for the user to rest and sleep.
As a specific example, as shown in fig. 9, the first preset mode is a large bed mode, at this time, the second row of seats 4 is linked with the front row of seats 3, the front row of seats 3 is adjusted forward to the forefront, the second row of seats 4 slide to the forefront, the backrest of the second row of seats 4 falls down backward and the cushion of the third row of seats 5 is leveled, and the large bed mode is realized. To avoid collision between the movable island 1 and the second row seat 4, the movable island 1 is first moved to the front when the large bed mode is activated.
In some embodiments, the present invention further provides a control method for controlling the vehicle according to any one of the above embodiments, where the control method includes the steps of controlling the two second row seats 4 to move to a preset position after receiving an instruction to enter the second preset mode, and controlling the movable center island 1 to move between the two second row seats 4.
As a specific example, as shown in fig. 10, the second preset mode is a four-seat mode, when the user clicks the virtual key of the four-seat mode on the screen, the second row of seats 4 automatically adjusts to the design position, and prompts the user to retract the armrests 6 on the screen popup window, then the backrest of the third row of seats 5 is tilted forward, and the movable middle island 1 moves backward to the stroke rear dead center. At this time, the movable center island 1 is located in the middle of the two rows of seats, and the vehicle has four spaces which are wide. When receiving a command to enter the four-seat mode, the third-row seat 5 is provided with an occupant detection sensor 19 to detect whether or not an article is present on the seat, and if an occupancy signal is detected, the backrest of the third-row seat 5 is kept stationary.
As shown in fig. 11, occupant detection sensors 19 for detecting whether a person is seated may be provided on the front seat 3 and the third seat 5.
