Specifically, the ottoman actuator 13r rotates the ottoman 5r between a deployed position developed toward the rear seat 1r and a retracted position retracted toward the vehicle front relative to the deployed position. Thereby, the ottoman actuator 13r can adjust the rotational position of the ottoman 5r. In the present embodiment, the retracted position is also a storage position where the ottoman 5r is stored in the seatback 3f. In the following description, the inclination of the ottoman 5r based on the ottoman 5r located at the retracted position is also referred to as "the angle θ of the ottoman 5r".

Next, the electrical configuration of the present embodiment will be described.
The vehicle is provided with a front ECU 15 f that controls the actuators 11 f and 12 f, and a rear ECU 15 r that controls the actuators 11 r, 12 r, and 13 r. The front ECU 15 f and the rear ECU 15 r are connected via the in-vehicle network 16. In the present embodiment, the front ECU 15 f corresponds to an example of the “vehicle seat control device”.

  The front ECU 15 f has a memory 31 f as an example of a storage unit. The memory 31f stores a plurality of set front seat positions of the front seat 1f. The set front seat position is, for example, a drop-off position preset as a position at which a passenger can easily get off the vehicle, and the front seat 1f as far forward as possible to widen the space between the front seat 1f and the rear seat 1r. And the registered sheet position registered according to the preference of the occupant.

  The front ECU 15 f is connected to the motors M 1 f and M 2 f, and operates the seat element SE f (the seat cushion 2 f and the seat back 3 f) through the supply of drive power to the motors M 1 f and M 2 f. That is, the front ECU 15 f operates the seat element SEf to change the seat position of the front seat 1 f.

  Specifically, the motors M1f and M2f are provided with rotation sensors S1f and S2f that output pulse signals synchronized with the rotation. The pulse signals Sp1f and Sp2f output from the rotation sensors S1f and S2f are synchronized with the operation of the sheet element SEf driven by the actuators 11f and 12f. The front ECU 15 f detects the position of the sheet element SEf by counting (accumulating) pulse changes of the pulse signals Sp 1 f and Sp 2 f based on a preset initial value.

  Further, a front operation unit 20f for adjusting the position of the seat element SEf by the operation of the occupant is connected to the front ECU 15f. The front operation unit 20f is provided at a position corresponding to the front seat 1f, for example, a position such as a door on the side of the front seat 1f, which is easy for the seat occupant of the front seat 1f to operate. The front operation unit 20f includes a first auto switch 21Af as an example of a "front auto switch" and a first manual switch 21Mf as an example of a "front manual switch".

  The first auto switch 21Af is a switch for automatically operating the front seat 1f to the set front seat position stored in the memory 31f, and the first manual switch 21Mf is a switch for manually operating the front seat 1f It is. For this reason, it is preferable that the first auto switch 21Af has a plurality of switches associated with the plurality of set front seat positions stored in the memory 31f. On the other hand, it is preferable that the first manual switch 21Mf has a switch for adjusting the sliding position of the seat cushion 2f and a switch for adjusting the reclining position of the seatback 3f. The front operation unit 20f preferably includes a switch for stopping the front seat 1f in operation automatically by the operation of the first auto switch 21Af.

Then, the front ECU 15 f controls the position of the sheet element SEf of the front seat 1 f based on various signals input, and operates the front seat 1 f.

  The rear ECU 15r has a memory 31r as an example of a storage unit. The memory 31 r stores a plurality of set rear seat positions of the rear seat 1 r. The set rear seat position is, for example, a drop-off position preset as a position where the passenger can easily get off when getting off the vehicle, a registered seat position registered according to the preference of the passenger, or the like.

  The rear ECU 15r is connected to the motors M1r, M2r, and M3r, and operates the seat element Ser (the seat cushion 2r, the seatback 3r, and the ottoman 5r) through the supply of drive power to the motors M1r, M2r, and M3r. That is, the rear ECU 15r operates the respective seat elements Ser to change the seat position of the rear seat 1r.

  In detail, the motors M1r, M2r, and M3r are provided with rotation sensors S1r, S2r, and S3r that output pulse signals synchronized with their rotations, similarly to the motors M1f and M2f. Similar to the front ECU 15f, the rear ECU 15r detects the position of the sheet element SEr by counting the pulse change of the pulse signals Sp1r, Sp2r, Sp3r based on a preset initial value.

  The rear ECU 15r is connected to a rear operation unit 20r for adjusting the positions of the seat elements SEf, SEr by the operation of the occupant. The rear operation portion 20r is provided at a position corresponding to the rear seat 1r, for example, at a position such as a door on the side of the rear seat 1r which is easy for the seated person of the rear seat 1r to operate. The rear operation unit 20r includes a second auto switch 22Ar as an example of a "rear auto switch", a second manual switch 22Mr as an example of a "rear manual switch", a third auto switch 23Ar, and a third manual switch 23Mr. And.

  The second auto switch 22Ar is a switch substantially similar to the first auto switch 21Af, and the second manual switch 22Mr is a switch substantially similar to the first manual switch 21Mf. That is, the second auto switch 22Ar and the second manual switch 22Mr are common in that they are switches for operating the front seat 1f when compared with the first auto switch 21Af and the first manual switch 21Mf. The difference is that they are provided at corresponding positions.

  The third auto switch 23Ar is a switch for automatically operating the rear seat 1r up to the set rear seat position stored in the memory 31r, and the third manual switch 23Mr is a switch for operating the rear seat 1r manually. For this reason, it is preferable that the third auto switch 23Ar have a plurality of switches associated with the plurality of set rear seat positions stored in the memory 31r. On the other hand, it is preferable that the third manual switch 23Mr has a switch for adjusting the sliding position of the seat cushion 2r, a switch for adjusting the reclining position of the seatback 3r, and a switch for adjusting the rotational position of the ottoman 5r. Further, the rear operation unit 20r stops the rear seat 1r in operation automatically by the switch for stopping the front seat 1f in operation by the operation of the second auto switch 22Ar and the operation of the third auto switch 23Ar. And a switch.

  In addition to the operation input signal Sswr according to the operation input to the rear operation unit 20r, various signals such as an ignition signal Sig and a signal from the front ECU 15f are input to the rear ECU 15r via the in-vehicle network 16. Then, the rear ECU 15r controls the position of the seat element SEr of the rear seat 1r based on various signals inputted, and operates the rear seat 1r.

Next, control contents of the front ECU 15 f and the rear ECU 15 r will be described in detail.
When the front automatic operation start condition is satisfied, the front ECU 15 f drives the actuators 11 f and 12 f to automatically operate the front seat 1 f up to the set front seat position. Specifically, when the start condition is satisfied, the front ECU 15 f automatically operates the sheet element SEf such that the position of the sheet element SEf corresponds to the set front seat position. In the following description, operation of the front seat 1 f is also referred to as “front automatic operation” when the front automatic operation start condition is satisfied. In the front ECU 15f, the front automatic operation start condition is satisfied, for example, when the first auto switch 21Af or the second auto switch 22Ar is operated.

  When the first manual switch 21Mf or the second manual switch 22Mr is operated by a passenger or the like, the front ECU 15f operates the front seat 1f based on the operation content of the first manual switch 21Mf or the second manual switch 22Mr. Specifically, while the first manual switch 21Mf or the second manual switch 22Mr is operated, the front ECU 15f causes the seat cushion 2f to slide or the seatback 3f to recline. In the following description, operating the front seat 1 f by operating the first manual switch 21 Mf or the second manual switch 22 Mr is also referred to as “front manual operation”.

Further, in this respect, in the present embodiment, it can be said that the front ECU 15 f includes the control unit 15 f 1 that executes the front automatic operation and the front manual operation.
The rear ECU 15r controls the actuators 11r, 12r, and 13r when the rear automatic operation start condition is satisfied, and automatically operates the rear seat 1r to the set rear seat position. Specifically, when the start condition is satisfied, the rear ECU 15r automatically operates the seat element Ser so that the position of the seat element Ser becomes the position corresponding to the set rear seat position. In the following description, the operation of the rear seat 1 r is also referred to as “rear automatic operation” when the rear automatic operation start condition is satisfied. In the rear ECU 15r, the rear automatic operation start condition is satisfied, for example, when the third auto switch 23Ar is operated.

  The rear ECU 15r operates the rear seat 1r based on the operation content of the third manual switch 23Mr when the third manual switch 23Mr is operated by an occupant or the like. Specifically, while the third manual switch 23Mr is operated, the rear ECU 15r slides the seat cushion 2r or reclines the seatback 3r. In the following description, operating the rear seat 1r by operating the third manual switch 23Mr is also referred to as “rear manual operation”.

  By the way, in the vehicle as described above, since the front seat 1f and the rear seat 1r are arranged in the front-rear direction of the vehicle, it is difficult for a seated person of the front seat 1f to check a situation of a seated person of the rear seat 1r. That is, the seated person of the front seat 1f does not easily check whether the seated person of the rear seat 1r uses the ottoman 5r. Therefore, when the seat occupant of the rear seat 1r uses the ottoman 5r and the seat occupant of the front seat 1 f operates the first auto switch 21Af and the front automatic operation is executed, the seat occupant of the rear seat 1r is It may cause discomfort.

  In addition, even if the occupant of the rear seat 1r is not using the ottoman 5r disposed at the unfolded position, the occupant of the front seat 1f operates the first auto switch 21Af, and the front automatic operation is performed. If this is done, the following problems may occur. That is, the space between the front seat 1f and the rear seat 1r is narrowed due to the execution of the front automatic operation, which may give a seated person of the rear seat 1r a feeling of tightness.

  Therefore, when the ottoman 5r is in the unfolded position, the rear ECU 15r outputs a signal for limiting the execution of the front automatic operation (hereinafter, "front automatic operation restriction signal Sli") to the front ECU 15f. Then, when the front auto operation limit signal Sli is input, the front ECU 15 f restricts the execution of the front auto operation. Thus, when the ottoman 5r is in the unfolded position, the execution of the front automatic operation is restricted even if the seat occupant of the front seat 1f operates the first auto switch 21Af. From this point of view, in the present embodiment, it can be said that the front ECU 15 f is provided with the limiting portion 15 f 2 that limits the execution of the front automatic operation.

  In addition, when the seated person of the front seat 1f operates the first manual switch 21Mf and the front manual operation is executed, the operation of the front seat 1f is made immediate by stopping the operation of the first manual switch 21Mf. You can stop it. Therefore, when the front manual operation is performed in a situation where the occupant of the rear seat 1r uses the ottoman 5r, the occupant of the rear seat 1r feels more uncomfortable than when the front automatic operation is executed. It is hard to give (a feeling of tightness). Therefore, the front ECU 15f does not restrict the execution of the front manual operation regardless of whether the front automatic operation restriction signal Sli is input.

Next, with reference to a flowchart shown in FIG. 2, a flow of processing executed by the rear ECU 15 r to execute the rear auto operation and the rear manual operation will be described.
As shown in FIG. 2, the rear ECU 15 r determines whether the angle θ of the ottoman 5 r is smaller than the determination angle θth (step S <b> 11). When the angle θ of the ottoman 5r is equal to or greater than the determination angle θth (step S11: NO), the rear ECU 15r outputs the front automatic operation restriction signal Sli toward the front ECU 15f (step S12), and the process proceeds to the next step S13. Transition. On the other hand, if the angle θ of the ottoman 5r is less than the determination angle θth (step S11: YES), the rear ECU 15r shifts the process to the next step S13.

  As shown in FIG. 1, the ottoman 5r of this embodiment can also be used in a state of being disposed between the retracted position and the use position. Therefore, the rear ECU 15r outputs the front automatic operation restriction signal Sli to the front ECU 15f not only when the ottoman 5r is located at the unfolded position but also when the angle θ of the ottoman 5r is equal to or greater than the determination angle θth. It is preferable that the determination angle θth be appropriately set in accordance with the rotation trajectory and the rotation radius of the ottoman 5r.

  In step S13, the rear ECU 15r determines whether the third manual switch 23Mr provided on the side of the rear seat 1r is operated. When the third manual switch 23Mr is operated (step S13: YES), the rear ECU 15r executes a rear manual operation according to the operation content of the third manual switch 23Mr (step S14). That is, while the third manual switch 23Mr is operated, the rear ECU 15r operates the seat element SEr of the rear seat 1r. Thereafter, the rear ECU 15 r ends the present process.

  In step S13, when the third manual switch 23Mr is not operated (step S13: NO), it is determined whether the third auto switch 23Ar provided on the side of the rear seat 1r is operated (step S15) . When the third auto switch 23Ar is operated (step S15: YES), the rear ECU 15r executes a rear auto operation (step S16). In other words, the rear ECU 15r operates the sheet element SEr of the rear seat 1r so as to be the set rear seat position corresponding to the operated third auto switch 23Ar. Thereafter, the rear ECU 15 r ends the present process. In step S15, when the third auto switch 23Ar is not operated (step S15: NO), the rear ECU 15r ends the present process.

  Thus, in the present embodiment, the rear ECU 15r executes the rear auto operation when the third auto switch 23Ar is operated regardless of the angle θ of the ottoman 5r, and the third manual switch 23Mr is operated. Performs the rear manual operation. The reason why the rear ECU 15r does not restrict the rear auto operation accompanying the operation of the third auto switch 23Ar is the same as the reason why the front ECU 15f does not restrict the front auto operation accompanying the operation of the second auto switch 22Ar.

  Next, the flow of processing executed by the front ECU 15 f to execute the front automatic operation and the front manual operation will be described with reference to the flowchart shown in FIG. 3.

  As shown in FIG. 3, the front ECU 15f determines whether the first manual switch 21Mf provided on the side of the front seat 1f or the second manual switch 22Mr provided on the side of the rear seat 1r is operated. (Step S21). When the first manual switch 21Mf or the second manual switch 22Mr is operated (step S21: YES), the front ECU 15f performs the front manual operation according to the operation content of the first manual switch 21Mf or the second manual switch 22Mr. Execute (step S22). That is, while the first manual switch 21Mf or the second manual switch 22Mr is operated, the front ECU 15f operates the sheet element SEf of the front seat 1f. Thereafter, the front ECU 15 f ends the present process.

  On the other hand, in step S21, when neither the first manual switch 21Mf nor the second manual switch 22Mr is operated (step S21: NO), the front ECU 15f sets the second auto switch 22Ar provided on the side of the rear seat 1r. Is determined (step S23). If the second auto switch 22Ar is operated (step S23: YES), the front ECU 15f executes a front auto operation (step S24). That is, the front ECU 15f executes the front automatic operation regardless of whether the front automatic operation restriction signal Sli is output from the rear ECU 15r.

  In step S23, when the second auto switch 22Ar is not operated (step S23: NO), the front ECU 15f determines whether or not the first auto switch 21Af provided on the side portion of the front seat 1f is operated. (Step S25). When the first auto switch 21Af is not operated (step S25: NO), the front ECU 15f ends the present process.

  On the other hand, when the first auto switch 21Af is operated (step S25: YES), the front ECU 15f determines whether the front auto operation restriction signal Sli is output from the rear ECU 15r (step S26). When the front automatic operation restriction signal Sli is output (step S26: YES), the rear ECU 15r ends the present process. That is, in this case, the front auto operation is not executed even if the first auto switch 21Af is operated.

  On the other hand, when the front automatic operation restriction signal Sli is not output (step S26: NO), the rear ECU 15r shifts the process to step S24. That is, in this case, the front auto operation is performed by the operation of the first auto switch 21Af.

  Thus, in the present embodiment, the front ECU 15f executes the front manual operation when the first manual switch 21Mf and the second manual switch 22Mr are operated regardless of the angle θ of the ottoman 5r, and the second auto switch When 22Ar is operated, the front automatic operation is performed. On the other hand, when the first auto switch 21Af is operated, the front ECU 15f executes the front automatic operation if the angle θ of the ottoman 5r is smaller than the determination angle θth, and the angle θ of the ottoman 5r is greater than the determination angle θth If there is, limit the execution of the front auto operation.

Next, the operation and effects of the present embodiment will be described.
(1) When the ottoman 5r is at the retracted position, the front auto operation is performed when the occupant of the front seat 1f operates the first auto switch 21Af. On the other hand, when the ottoman 5r is located at the unfolded position, the front automatic operation is not executed even if the occupant of the front seat 1f operates the first automatic switch 21Af. Therefore, when there is a possibility that the seated person of the rear seat 1r is using the ottoman 5r, the front ECU 15f suppresses giving discomfort to the seated person of the rear seat 1r in that the execution of the front automatic operation is limited. it can.

  Even when the ottoman 5r is positioned at the unfolded position and the seated person of the rear seat 1r does not use the ottoman 5r, when the rear seat 1r operates rearward of the vehicle by the front automatic operation, the rear seat 1r May be cramped to the occupants of the In this case, this embodiment can suppress giving a seated person of the rear seat 1r a feeling of tightness.

  (2) Even when the ottoman 5r is in the unfolded position, the front automatic operation is performed when the occupant of the rear seat 1r operates the second auto switch 22Ar. The front automatic operation in this case is based on the intention of the person sitting on the rear seat 1r, and therefore, even if the front automatic operation is performed, the person sitting on the rear seat 1r does not easily feel discomfort. Therefore, the front ECU 15f can suppress the operation of the front seat 1f from being excessively restricted while suppressing giving discomfort to the seated person of the rear seat 1r.

  (3) Regardless of the position of the ottoman 5r, when the seated person of the front seat 1f operates the first manual switch 21Mf, the front manual operation is performed. In this case, the seat occupant of the front seat 1 f stops the operation of the first manual switch 21 Mf by communication between the seat occupant of the front seat 1 f and the seat occupant of the rear seat 1 r, such as voice calling. This is because the manual operation can be stopped immediately. Therefore, the front ECU 15f can suppress the operation of the front seat 1f from being excessively restricted while suppressing giving discomfort to the seated person of the rear seat 1r.

  (4) Even if the ottoman 5r is positioned between the in-use position and the unfolded position, if the ottoman 5r is in the state of projecting toward the rear seat 1r, the ottoman 5r is in the in-use position Similarly, the front auto operation is not executed by the operation of the first auto switch 21Af. In other words, when the angle θ of the ottoman 5r is equal to or greater than the determination angle θth, the front automatic operation is not performed by the operation of the first automatic switch 21Af. For this reason, it is possible to further suppress giving a seated person of the rear seat 1r a feeling of discomfort (a feeling of tightness).

The above embodiment may be modified as shown below.
When the front seat 1f is used as a driver's seat, the rear seat 1r may be used as a rear seat for the driver's seat. When the front seat 1f is used as the second row seat of the vehicle, the rear seat 1r may be used as the rear seat of the second row seat, that is, the third seat of the vehicle.

  The determination angle θth may be a variable. For example, the determination angle θth may be changed according to a reclining angle which increases as the seat back 3f is inclined backward. Specifically, when the reclining angle is large, the determination angle θth may be smaller than when the reclining angle is small.

  The front ECU 15f may execute the front automatic operation exceptionally even when the front automatic operation restriction signal Sli is input in step S26. Specifically, when the seat element SEf of the front seat 1f operates rearward of the vehicle by the execution of the front automatic operation, the front ECU 15f may limit the execution of the front automatic operation. On the other hand, when the seat element SEf of the front seat 1 f operates forward of the vehicle by the execution of the front automatic operation, the front ECU 15 f may permit the execution of the front automatic operation. This is because when the seat element SEf of the front seat 1f operates forward of the vehicle, the seat occupant of the rear seat 1r feels uncomfortable (cramped feeling) when the seat element SEf of the front seat 1f operates backward of the vehicle It is difficult to give.

  The front ECU 15 f may select whether or not to execute the front auto operation based on the presence or absence of the front auto operation restriction signal even when the second auto switch 22 Ar is operated in step S 23. .

  When the front seat 1f is used as the driver's seat, the front ECU 15f determines that the front automatic operation start condition is satisfied when the ignition signal Sig indicates the off state and the door on the side of the driver's seat is opened. You may In this case, step S25 in FIG. 3 may be a process of determining whether or not the front automatic operation start condition is satisfied.

The front ECU 15 f may perform the process corresponding to step S11 in FIG. 2 in step S26 in FIG. 3.
The rear ECU 15r may consider that the ottoman 5r is in the deployed position when the ottoman 5r is in the position between the retracted position and the deployed position. In this case, even if the ottoman 5r slightly rotates from the retracted position, the execution of the front auto operation accompanying the operation of the first auto switch 21Af is restricted.

  The retracted position of the ottoman 5r may be a position retracted to the seat back 3f rather than the deployed position of the ottoman 5r. For example, when the ottoman 5r is located at the retracted position, the tip of the ottoman 5r may be separated from the seat back 3f.

  The ottoman 5r may be provided on the seat cushion which is the seat element SEf of the front seat 1f. In this case, the ottoman 5r may be configured to move back and forth or extend and retract between the retracted position stored in the seat cushion and the deployed position deployed toward the rear seat 1r.

The ottoman 5r may be configured to be located at only two positions, the deployed position and the retracted position.
The front seat 1 f may not include the ottoman actuator 13 r. In this case, it is preferable that a passenger or the like manually move the ottoman 5r between the deployed position and the retracted position.

  The front seat 1 f may be a power seat configured to allow operations other than the sliding motion of the seat cushion 2 f and the reclining motion of the seat back 3 f. For example, the front seat 1f may be configured to move the entire seat cushion 2f in the vertical direction of the vehicle, or to move the front end of the seat cushion 2f up and down (tilt) with respect to the rear end You may configure it. The same applies to the rear seat 1r.

  In the above embodiment, the actuators 11f and 12f with the motors M1f and M2f as drive sources and the actuators 11r, 12r and 13r with the motors M1r, M2r and M3r as drive sources are used, but the present invention is not limited thereto. The configuration of the actuator can be changed as appropriate as long as the position of Sr can be adjusted. Further, the positions of the sheet elements SEf and SEr may not be detected based on the pulse signals Sp1 f and Sp2 f and the pulse signals Sp1 r, Sp2 r and Sp3 r, for example, displacement sensors may be provided on the sheet elements SEf and SEr to directly detect the positions. The method of detecting the position can be changed as appropriate.
