     TECHNICAL FIELD 
     Embodiments of the present disclosure relate to a seat automatic arrangement method and apparatus of an autonomous driving vehicle and, more particularly, a seat automatic arrangement method and apparatus of an autonomous driving vehicle, the method and apparatus being able to automatically arrange seats of a vehicle in a seat-facing mode from a standard mode through remote control. 
     BACKGROUND 
     An autonomous driving vehicle, which is a smart vehicle employing an autonomous technology enabling the vehicle to go a destination by itself even though a driver does not operate the steering wheel, acceleration pedal, brake, etc., is recently being rapidly developed. 
     If autonomous driving is generally used, a driver can select a manual driving mode in which the driver manually drives and an autonomous driving mode in which a vehicle goes by itself to a destination without the driver manually driving. 
     In the autonomous driving mode, various modes can be implemented, depending on the arrangement state of seats such as an individual mode in which passengers in the seats individually take a rest in a comfortable posture and a seat-facing mode (including a facing mode, a face-to-face mode, a conversation mode) in which the passengers in the first row seats and the second row seats face each other. It is required to be able to remotely adjust the positions, postures, etc. of seats in order to implements various seat modes. 
     Meanwhile, there is a defect that if there is no priority in the arrangement processes when seats are remotely adjusted to be moved and arranged in the seat-facing mode, interference with surrounding parts is generated when the seats are moved, and accordingly, arrangement of the seats is not performed well. 
     The description provided above as a related art of the present disclosure is just for helping to understand the background of the present disclosure and should not be construed as being included in the related art known by those skilled in the art.

     The seats  100  may be configured to be able to move forward and rearward on seat rails, or, if necessary, may be configured to be able to move without a seat rail, and in this case, the seats  100  can be moved using 2D or 3D coordinates. 
     The console  300  having a console motor  400  may be installed between the driver seat  111  and the passenger seat  112 . 
     The console  300  may include a front console  310  and a rear console  320  that are separated from each other, and the console motor  410  includes a front console motor  410  and a rear console motor  420  provided at the front console  310  and the rear console  320 , respectively. 
     The front console  310  and the rear console  320  may be configured to individually move forward and rearward by power from the front console motor  410  and the rear console motor  420 . The front console motor  410  and the rear console motor  420  each have a sensor and the operation thereof is controlled by the console controller  500  using the sensors.

     It is apparent that the console  300  may also be configured to have the same movement as the seats  100 . 
     A seat automatic arrangement method of an autonomous driving vehicle according to the present disclosure is described hereafter with reference to  FIGS.  1  to  3   . 
     The method may include a signal generation step in which a user operates the operation device  200  and a signal corresponding to seat-facing mode is generated; a moving step of changing the positions and postures of the console  300 , the first row seats  110 , and the second row seats  120  to safety regions where interference does not occur when the signal corresponding to the seat-facing mode is generated; a rotating step of rotating the first row seats  110  such that the first row seats  110  face the second row seats  120  after the moving step; and a returning step of returning the positions and postures of the console  300 , the first row seats  110 , and the second row seats  120  to reference positions or positions designated by a user after the rotating step. After the returning step is finished, changing the seats  100  of the vehicle into the seat-facing mode that is the final target is finished. 
     When the vehicle is turned on and a signal corresponding to the seat-facing mode is generated by a passenger operating the operation device  200  (step S 1 ), the seats  100  of the vehicle may be finally changed from the standard mode, which is the current arrangement state, to the seat-facing mode that the passenger wants. 
     The standard mode of the seats  100  may be defined as a mode of the state in which the first row seats  110  including the driver seat  111  and the passenger seat  112  and the second row seats  120  positioned behind the first row seats  110  all face the front. 
     The seat-facing mode (a facing mode, a face-to-face mode, a conversation mode) may be defined as a mode in which the first row seats  110  and the second row seats  120  face each other, as shown in  FIG.  3 G . 
     When the operation device  200  is operated and a signal for the seat-facing mode is generated (step S 1 ) in the standard mode shown in  FIG.  3 A , the front console motor  410  and the rear console motor  420  may be controlled to operate by the console controller  500  in the moving step, as shown in  FIG.  3 B , whereby the front console  310  and the rear console  320  slide to safety regions by moving forward and rearward, respectively (step S 2 ). 
     The safety regions may be positions where interference with the first row seats  110  does not occur when the first row seats  110  are rotated in the rotating step shown in  FIGS.  3 C to  3 E . The front console  310  is moved forward to a front reference line L 1  and the rear console  320  is moved rearward to a rear reference line L 2 . 
     When the front console  310  is moved forward and the rear console  320  is moved rearward, in the moving step shown in  FIG.  3 B , the seat motors  600  may be controlled to operate by the seat controllers  700 , whereby the seatbacks  130  of the first row seats  110  are erected, and the first row-seats  110  and second row seats  120  all slide rearward and enter the safety regions (step S 3 ). 
     The angle of the seatbacks  130  may be adjusted by the reclining motors  630 , and the first row seats  110  and the second row seats  120  are moved rearward by the moving motors  620 . 
     Erecting the seatbacks  130  of the first row seats  110  and moving rearward the first row seats  110  and the second row seats  120  may be for preventing the first row seats  110  from being interfered with when the first row seats  110  are rotated in the rotating step shown in  FIGS.  3 C to  3 E . 
     After the moving step is performed, the rotating step of rotating the first row seats  110  may be performed. 
     That is, after the first row seats  110  and the second row seats  120  are moved rearward through step S 3 , the driver seat  111  and the passenger seat  112  of the first row seats  110  may be rotated rearward to face the second row seats  120  (step S 4 ). 
     When the first row seats  110  are rotated, the driver seat  111  starts to be rotated first by the swivel motor  510 , as shown in  FIG.  3 D , the passenger seat  112  may start to be rotated when the driver seat  111  is rotated over 50%, as shown in  FIG.  3 D , and then the driver seat  111  may finish being rotated first and then sequentially the passenger seat  112  may finish being rotated, as shown in  FIG.  3 E . 
     The reason of rotating the driver seat  111  and the passenger seat  112  with a predetermined time difference may be for preventing interference therebetween. 
     After the rotating step is performed, the returning step in which the front console  310  and the rear console  320  may be returned to the reference positions or positions designated by a user and the angle of the seatbacks  130  of the first row seats  110  and the positions of the first row seats  110  and the second row seats  120  are returned to the reference positions or positions designated by a user is performed. 
     That is, after the first row seats  110  finish being rotated rearward through step S 4 , the front console  310  that has been moved forward and the rear console  320  that has been moved rearward are moved rearward and forward, respectively, as shown in  FIG.  3 F , and returned to the reference positions or the positions designated by a user shown in  FIG.  3 A  by the front console motor  410  and the rear console motor  420  (step S 5 ). 
     Further, in the returning step shown in  FIG.  3 F , the seat motors  600  may be controlled to operate by the seat controllers  700 , the seatbacks  130  of the first row seats  110  may be returned to the reference positions or the positions designated by a user shown in  FIG.  3 A , and the first row seats  110  and the second row seats  120  may be all moved forward and returned to the reference positions or the positions designated by a user shown in  FIG.  3 A  (step S 6 ). 
     The angle of the seatbacks  130  may be adjusted by the reclining motors  630 , and the first row seats  110  and the second row seats  120  are returned by the moving motors  620 . 
     After the front console  310 , the rear console  320 , the first row seats  110 , and the second row seats  120  are returned, the process of changing the seats  100  of the vehicle into the seat-facing mode in which the first row seats  110  and the second row seats  120  face each other, as shown in  FIG.  3 G , may be finished (step S 7 ). 
     Meanwhile, when the seats  100  and the console  300  in the vehicle are changed into the seat-facing mode, the vehicle controller  800  may determine whether the seats  100  and the console  300  are stuck due to interference with the surrounding parts. 
     The seat controllers  700  may detect the current positions and postures of the seats  100  using Hall sensors of the swivel motor  610 , the moving motor  620 , and the reclining motor  630  of the seat motor  600  and transmit the current positions and postures to the vehicle controller  800 . The vehicle controller  800  determines whether the seats  100  are interfered with by the surrounding parts while moving for the seat-facing mode with reference to the information about the seats  100  transmitted from the seat controllers  700  and the paths for moving for the seat-facing mode. 
     The vehicle controller  800  may receive the position of the console  300 , which is a surrounding part around the seats  100 , though a Hall sensor at the console motor  400 , and determines also whether the current position of the console  300  interferes with the seats  100  when the seats  100  are moved for the seat-facing mode. 
     When the seats  100  and the console  300  are stuck due to the surrounding parts (a dashboard, doors, etc.) when they are changed to the seat-facing mode, an error signal may be transmitted to the operation device  200  by control of the seat controllers  700 , the console controller  500 , and the vehicle controller  800 , so a passenger can visually and aurally recognize the error signal. 
     That is, when a seat  100  is stuck while moving, load may be generated in the corresponding motor and an error signal of the motor is transmitted to the operation device  200  that is configured to be operated by a passenger, and the passenger visually or aurally recognizes the error signal transmitted to the operation device  200  and stops the operation, whereby damage and breakage of parts can be prevented. 
     Further, according to an embodiment of the present disclosure, the seats  100  or the console  300  that is stuck in the process of entering the seat-facing mode may be returned to the position and posture in the previous step or is stopped so that damage and breakage of parts such as the motor can be prevented. 
     Further, according to an embodiment of the present disclosure, when the vehicle is turned off after the seats  100  are changed to the seat-facing mode, the seats  100  and the console  300  may be automatically changed to the standard mode, thereby preparing for the next operation. 
     The seat automatic arrangement method and apparatus of an autonomous driving vehicle according to the present disclosure, as described above, have an advantage that it is possible to automatically arrange the seats  100  in the vehicle into the seat-facing mode through remote control, and particularly, it is possible to prevent interference when moving the seats  100  by arranging the seats  100  in accordance with priority when arranging the seats  100  into the seat-facing mode, thereby being able to more smoothly arrange the seats  100  into the seat-facing mode in an autonomous driving vehicle. 
     Although the present disclosure was described with reference to specific embodiments shown in the drawings, it is apparent to those skilled in the art that the present disclosure may be changed and modified in various ways without departing from the scope of the present disclosure which is described in the following claims.
