On the other hand, when the seating sensor 145 is not turned on (ST07: No), the process further proceeds to ST09, and it is determined whether a predetermined time has elapsed from when the door is closed.
If the predetermined time has already elapsed (ST09: Yes), it is determined that the passenger has stopped getting on and the vehicle door has been closed, and the process proceeds to ST21 where the door release sensor 143 is forcibly turned off to open the vehicle door. Lock and proceed to ST19. On the other hand, if the predetermined time has not elapsed (ST09: No), it is determined that the occupant is getting on and is going to sit down, and the process returns to ST07.

After executing the control 1 of the belt assist device 50 in ST08, the process proceeds to ST10 and the control 1 of the sheet switching device is executed. Details of the control will be described later.
After performing control of the sheet switching device in ST10, the process proceeds to ST11, and it is determined whether the door opening / closing sensor 144 is turned on.
When the door opening / closing sensor 144 is turned on (ST11: Yes), the occupant intends to get off the vehicle by opening the vehicle door, so the process proceeds to ST12, and the illumination device 130 is illuminated in the see-through mode shown in FIGS.
On the other hand, when the door opening / closing sensor 144 is not turned on (ST11: No), it returns to ST10 on the assumption that the occupant is still in the vehicle while the vehicle door is closed.

After the lighting in the see-through mode is turned on in ST12, the process proceeds to ST13 and the control of the side support device 70 is executed. Details of the control will be described later.
After performing the control of the side support device 70 in ST13, the process proceeds to ST14, and it is determined whether the door opening / closing sensor 144 is turned off.
When the door opening / closing sensor 144 is turned off (ST14: Yes), it is determined that the passenger has got off and closed the door, and the process proceeds to ST15, where the lighting device 130 is illuminated in the standby mode shown in FIG.
On the other hand, when the door opening / closing sensor 144 is not turned off (ST14: No), it is determined that the occupant is getting off, and the process returns to ST14.

After the lighting in the standby mode is turned on in ST15, the process proceeds to ST16 and the control 2 of the belt assist device 50 is executed. Further, the process proceeds to ST17 to execute control 2 of the sheet switching device.
Details of these controls will be described later.

After the control of the belt assist device 50 and the sheet switching device is executed in ST16 and ST17, the process proceeds to ST18 and it is determined whether the door release sensor 143 is turned off.
When the door release sensor 143 is turned off (ST18: Yes), since the occupant is about to leave the vehicle door and leave the vehicle, the process proceeds to ST19 and the illumination device 130 is turned off.
On the other hand, when the door release sensor 143 is not turned off (ST018: No), the process further proceeds to ST20, and it is determined whether a predetermined time has elapsed since the door was closed.
If the predetermined time has already passed (ST20: Yes), it is determined that the passenger has forgotten to lock the vehicle door, and the process proceeds to ST21 to forcibly turn off the door release sensor 143 and lock the vehicle door. Above, it progresses to ST19. On the other hand, when the predetermined time has not elapsed (ST20: No), it is determined that the occupant is about to lock the vehicle door and the process returns to ST18.
The process of FIGS. 33A and 33B is completed through the above ST01 to ST21.

  With the above-described series of processing flows, the vehicle unit U provides a total support from the riding operation to the seat belt installation, the seat switching operation, and the getting-off operation while lighting the occupant with a predetermined light emission pattern. Can be induced.

A seating sensor is also attached to the front seat located in front of the vehicle seat S as the rear seat, and a door opening / closing sensor is also attached to the front door, but the seating sensor and the door opening / closing sensor are on. Even if it is turned off, it is desirable to prevent the above-described series of processing flows from proceeding.
Desirably, when the person gets on and sits in the left seat of the rear seat and gets off, the above-described series of processing flow is executed, while the person gets on and sits in both the front seat and the right seat of the rear seat. When getting off, the lighting device 130 should always emit light in the standby mode.

In order to execute control of the seat switching device in ST10, the door opening / closing sensor 144 needs to be turned off in ST06 and the seating sensor 145 is turned on in ST07. For example, the vehicle door remains open. Even if the passenger is seated, the control of the seat switching device may be executed.
By doing so, for example, when the occupant wants to take a break while sitting while the vehicle door is open and the vehicle is stopped without running, the seat switching operation can be performed.

<< Control flow of belt assist device >>
Next, the control 1 of the belt assist device in ST08 will be described in detail with reference to FIG. 34A.
When the processing of the flowchart in FIG. 34A starts, first, in ST08-1, since the occupant has finished riding and is seated, the pick-up mode shown in FIGS. 28A to 28C is switched to the standby mode shown in FIGS. Turn on the lighting.

In ST08-1, after lighting in the standby mode, the process proceeds to ST08-2, where the occupant is seated on the vehicle seat S, but the seat belt 4 is not yet fastened, and driving power is supplied to the drive motor. Then, the movable member 55 is rotated from the storage position to the protruding position shown in FIG. 29A. As a result, the seat belt 4 is pushed forward and upward.
When the movable member 55 moves to the protruding position, it is desirable to stop the rotation operation of the drive motor and keep it in the hold state.

After starting the operation of the movable member 55 in ST08-2, the process proceeds to ST08-3, and it is determined whether the buckle sensor 146 is turned on.
When the buckle sensor 146 is turned on (ST08-3: Yes), it is assumed that the occupant is wearing the seat belt 4, the process proceeds to ST08-4, and the drive motor is reversely rotated to move the movable member 55 in FIG. 29A. Reverse rotation is performed from the protruding position to the storage position of FIG. 29B.
On the other hand, when the buckle sensor 146 is not turned on (ST08-3: No), the process further proceeds to ST08-5 to determine whether a predetermined time has elapsed from the start of the rotation operation of the movable member 55.
When the predetermined time has already passed (ST08-5: Yes), for example, the vehicle is stopped without running and the passenger is resting while sitting, and the process proceeds to ST08-4 to move the movable member 55. Rotate to the retracted position. On the other hand, if the predetermined time has not elapsed (ST08-5: No), it is determined that the occupant is about to wear the seat belt 4 and the process returns to ST08-3.

After starting the reverse operation of the movable member 55 in ST08-4, the process proceeds to ST08-6 to determine whether the movable member 55 has moved to the storage position.
When the movable member 55 has moved to the storage position (ST08-6: Yes), the process proceeds to ST08-7, and the supply of drive power to the drive motor is stopped. As a result, the movable member 55 is held while being in the storage position.
On the other hand, when the movable member 55 has not moved to the storage position (ST08-6: No), the process returns to ST08-6.
The process of FIG. 34A is completed through the above ST08-1 to ST08-7, and then the process proceeds to ST10 of FIG. 33B.

  According to the above processing flow, the belt assist device 50 can move a part of the seat belt 4 to a position where the seated passenger can easily reach before the seated passenger installs the seatbelt 4. After the belt 4 is mounted, the belt 4 is integrally stored in the vehicle seat S so as not to get in the way.

In ST08-5, when the seat sensor 145 is turned on and the buckle sensor 146 is not turned on even after a predetermined time has elapsed, the seated occupant is prompted to wear the seat belt 4. It is desirable to make a notification for the purpose (for example, blinking lighting of the lighting device 130).
More preferably, the notification may be performed only when the vehicle is operating.

  When the belt assist device 50 is operating, it is desirable that the control device 140 controls the side support device 70 so that it cannot operate.

Next, control part 2 of the belt assist device in ST16 will be described in detail with reference to FIG. 34B.
When the processing of the flowchart of FIG. 34B starts, first, in ST16-1, it is determined whether or not the movable member 55 has been protruded and stored.
When the movable member 55 remains protruding (ST16-1: Yes), the process proceeds to ST16-2, and the movable member 55 is reversely rotated to the storage position in FIG. 29B.
On the other hand, when the movable member 55 does not remain protruding (ST16-1: No), the process of FIG. 34B is terminated.

After starting the reverse operation of the movable member 55 in ST16-2, the process proceeds to ST16-3, and it is determined whether the movable member 55 has moved to the storage position.
When the movable member 55 has moved to the storage position (ST16-3: Yes), the process proceeds to ST16-4, and the supply of drive power to the drive motor is stopped. As a result, the movable member 55 is held while being in the storage position.
On the other hand, when the movable member 55 has not moved to the storage position (ST16-3: No), the process returns to ST16-3.
The process of FIG. 34B is terminated through the above ST16-1 to ST16-4, and the process proceeds to ST17 of FIG. 33B.

  With the above processing flow, it is possible to prevent the movable member 55 from protruding after the passenger gets off.

<< Sheet Switching Device Control Flow >>
Next, the control 1 of the sheet switching device in ST10 will be described in detail with reference to FIG. 35A.
When the processing of the flowchart of FIG. 35A starts, first, in ST10-1, it is determined whether the sheet changeover switch 147 is turned on.
When the seat changeover switch 147 is turned on (ST10-1: Yes), the seated occupant wants to move the vehicle seat S from the normal position in FIG. 30A to the reclining position in FIG. 30B in ST10-2. The lighting mode is switched on from the standby mode shown in 29B to the relax mode shown in FIGS. 30A and 30B. In step ST10-3, driving power is supplied to the sheet switching apparatus to drive the sheet switching apparatus.
On the other hand, when the seat changeover switch 147 is not turned on (ST10-1: No), the occupant wants to sit on the vehicle seat S at the normal position, and the process of FIG.

After the operation of the seat switching device is started in ST10-3, the process proceeds to ST10-4, and it is determined whether or not the vehicle seat S has moved to the reclining position (predetermined front position).
When the vehicle seat S has moved to the reclining position (ST10-4: Yes), the process proceeds to ST10-5, and the supply of drive power to the seat switching device is stopped. As a result, the vehicle seat S is held in the reclining position.
Note that when the supply of driving power is stopped, the sheet changeover switch 147 is controlled to be forcibly returned from on to off.
On the other hand, when the vehicle seat S has not moved to the reclining position (ST10-4: No), the process returns to ST10-3.

  After the operation of the sheet switching device is stopped in ST10-5, the process proceeds to ST10-6 to switch from the relax mode shown in FIGS. 30A and 30B to the standby mode shown in FIG.

After the lighting in the standby mode is turned on in ST10-6, the process proceeds to ST10-7, and it is determined whether the sheet changeover switch 147 is turned on again.
When the seat changeover switch 147 is turned on (ST10-7: Yes), it is assumed that the seated occupant wants to return the vehicle seat S from the reclining position of FIG. 31A to the normal position of FIG. 31B in ST10-8, FIG. The lighting mode is switched on from the standby mode shown in FIG. 31 to the relaxing mode shown in FIGS. In step ST10-9, driving power is supplied to the sheet switching apparatus, and the sheet switching apparatus is operated in reverse.
On the other hand, when the seat changeover switch 147 is not turned on (ST10-7: No), the occupant wants to sit on the vehicle seat S at the reclining position, and the process of FIG.

After starting the reverse operation of the seat switching device in ST10-9, the process proceeds to ST10-10, and it is determined whether the vehicle seat S has returned to the normal position.
When the vehicle seat S returns to the normal position (ST10-10: Yes), the process proceeds to ST10-11, and the supply of drive power to the seat switching device is stopped. As a result, the vehicle seat S is held in the normal position.
On the other hand, when the vehicle seat S has not moved to the normal position (ST10-10: No), the process returns to ST10-9.
The process of FIG. 35A is terminated through ST10-1 to ST10-11, and then the process proceeds to ST-11 of FIG. 33B.

  With the above-described series of processing flows, the seat switching device can switch the vehicle seat S between the normal position and the reclining position in order to improve the comfort of the seated passenger.

In order to move the vehicle seat S to be the rear seat from the normal position to the reclining position, it is preferable to move the front seat in front of the vehicle seat S in advance to the front side of the seat from the normal position.
Specifically, when the seat changeover switch 147 is turned on, the slide rail device, the reclining device, and the height link device mounted on the front seat are first operated to move the front seat to the position where the front seat is moved to the front side of the seat. It is good to leave it.
Then, when the front seat advances about half to the predetermined movement position, the vehicle seat S may start the switching operation.
By doing so, a sufficient space can be secured between the front seat and the rear seat, and a smooth switching operation between both the front seat and the rear seat can be realized.

Next, control part 2 of the sheet switching device in ST17 will be described in detail with reference to FIG. 35B.
When the process of the flowchart of FIG. 35B starts, first, in ST17-1, it is determined whether the vehicle seat S remains at the front predetermined position and has not returned to the normal position.
When the movable member 55 remains at a predetermined position in the front (ST17-1: Yes), the process proceeds to ST17-2, and the sheet switching device is reversely operated.
On the other hand, when the vehicle seat S does not remain at the predetermined position in front (ST17-1: No), the process of FIG. 35B is terminated.

After starting the reverse operation of the seat switching device in ST17-2, the process proceeds to ST17-3 to determine whether the vehicle seat S has returned to the normal position.
When the vehicle seat S returns to the normal position (ST17-3: Yes), the process proceeds to ST17-4, and the supply of drive power to the seat switching device is stopped. As a result, the vehicle seat S is held in the normal position.
On the other hand, when the vehicle seat S has not moved to the normal position (ST17-3: No), the process returns to ST17-2.
The process of FIG. 35B is terminated through the above ST17-1 to ST17-4, and then the process proceeds to ST-18 of FIG. 33B.

  According to the processing flow described above, it is possible to prevent the vehicle seat S from remaining in the reclining position after the passenger gets off, for example.

<< Control flow of side support device >>
Next, the control of the side support device in ST13 will be described in detail based on FIG.
When the process of the flowchart of FIG. 36 starts, first, in ST13-1, it is determined whether the seating sensor 145 remains on.
When the seating sensor 145 remains turned on (ST13-1: Yes), it is assumed that the seated occupant is about to get off the vehicle with the body approaching the opened vehicle door side. The side support device 70 is controlled to switch from the unlockable state to the unlockable state.
Here, the unlocking impossible state means a state in which the side support device 70 cannot operate, and specifically, a state in which the unlocking device 90 cannot release the locked state.
Further, the unlockable state means a state in which the side support device 70 can operate, and specifically, a state in which the lock release device 90 can release the locked state.
On the other hand, when the seating sensor 145 is not in the on state (ST13-1: No), it is assumed that the seated occupant has already got off the vehicle door, and the process of FIG. 36 is terminated.

After switching the side support device 70 to the unlockable state in ST13-2, the process proceeds to ST13-3 to determine whether the seating sensor 145 is turned off.
When the seating sensor 145 is turned off (ST13-3: Yes), it is determined that the seated passenger has finished getting off while being supported by the side support device 70, and the process proceeds to ST13-4 to control the side support device 70 again. Switch from the unlockable state to the unlockable state.
On the other hand, when the seating sensor 145 is not turned off (ST13-3: No), the process further proceeds to ST13-5, and it is determined whether a predetermined time has elapsed from the start of the switching control of the side support device 70.
When the predetermined time has already passed (ST13-5: Yes), the process proceeds to ST13-4, and the side support device 70 is switched to the unlocking disabled state. On the other hand, when the predetermined time has not elapsed (ST13-5: No), it is determined that the seated passenger is about to get off, and the process returns to ST13-3.
The process of FIG. 36 is terminated through ST13-1 to ST13-5, and then the process proceeds to ST-14 of FIG. 33B.

  With the above-described series of processing flows, the side support device 70 can assist the occupant to get off while stably securing the holdability of the occupant seated. Moreover, since it becomes the structure which does not incline the cushion side part 1c at the time of a boarding operation of a passenger | crew, consideration is given so that a passenger | crew can get on reliably.

In addition, when the side support device 70 is in the unlockable state, it is desirable that the control device 140 controls the belt assist device 50 and the sheet switching device so that they cannot operate.
That is, it is desirable to control the side support device 70 so as to operate with priority over the belt assist device 50 and the sheet switching device.

If the control device 140 has previously received a detection signal from a child seat detection sensor (not shown) before the above processing flow, the side support device 70 is forcibly maintained in an unlocking disabled state. You may control.
By doing so, when a child seat (not shown) is attached, a safety lock can be applied in advance for infants and children.
