A seat automatic arrangement method of an autonomous driving vehicle according to the present disclosure is described hereafter with reference to
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 S1), 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
When the operation device 200 is operated and a signal for the seat-facing mode is generated (step S1) in the standard mode shown in
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
When the front console 310 is moved forward and the rear console 320 is moved rearward, in the moving step shown in
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
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 S3, 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 S4).
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
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 S4, 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
Further, in the returning step shown in
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
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.
