Description

  The present invention relates to a vehicle seat slide control device, and more particularly to a vehicle seat slide control device that improves the dismountability by slidingly moving the position of a vehicle seat when an occupant gets out of the vehicle.

  Conventionally, as a slide control device for a vehicle seat, for example, as disclosed in Patent Document 1 below, when it is detected that the door of the vehicle is opened, the vehicle seat is used for facilitating the passenger to get out of the vehicle. It is known to improve the dismountability by expanding the foot space of the occupant by controlling the seat to retract to a predetermined slide amount or a predetermined standby position.

Japanese Utility Model Publication No. 6-74464

  However, in the vehicle seat control device of Patent Document 1, since the sliding amount or standby position of the vehicle seat to be moved back is constant, for example, there are no obstacles such as other vehicles or walls in the immediate vicinity of the door. Even in a situation where the door is greatly opened, that is, in a situation where it is easy to get off, it is necessary to wait until the vehicle seat is slid by a predetermined amount and stopped. Movement may be troublesome.

  The problem to be solved by the present invention is to provide a vehicle seat slide control device in which the amount of sliding of the vehicle seat is variable according to the degree of opening of the door so that the vehicle seat does not slide more than necessary when getting off the vehicle. It is to be.

  In order to solve the above-described problems, the present invention provides a seat sliding means for sliding a vehicle seat in the vehicle longitudinal direction, a getting-off start detecting means for detecting the start of getting off a passenger, a door opening and a door opening for detecting the opening degree thereof. A vehicle seat slide control device having a degree detection means, and variably sets a rear slide amount of the vehicle seat based on an opening degree of the door detected by the door opening degree detection means. The gist of the invention is that a slide amount setting means is provided.

  The slide control device for a vehicle seat having such a configuration releases the sliding amount of the vehicle seat to the rear when the vehicle seat is slid toward the rear of the vehicle in order to widen the passenger's foot space when the passenger gets off. It is configured to be able to be set variably based on the opening degree of the door, that is, the sliding amount to the rear of the vehicle seat is variable according to the opening degree of the door.

  Thereby, for example, when the opening degree of the door is large, the sliding movement of the vehicle seat is stopped early by sliding the vehicle seat with a short sliding amount corresponding thereto, and the dismounting property is improved. When the opening degree of the door is small, the vehicle seat can be slid by a long slide amount corresponding to the door opening degree, and the dismounting property can be improved. In other words, when the door opening is large, that is, when it is easy to get off, the sliding amount of the vehicle seat is set short, and when the door opening is small, that is, when it is difficult to get off, the sliding amount of the vehicle seat is increased. By setting, it is possible to eliminate the troublesomeness when the vehicle seat is slid more than necessary, while ensuring good dismounting properties. In addition, since the vehicle seat is not slid and moved more than necessary, when the amount of sliding of the vehicle seat can be shortened, the power consumption required by the seat slide means can be reduced accordingly.

  In this case, when the getting-off start of the occupant is detected by the getting-off start detecting means and the opening degree of the door is detected by the door opening degree detecting means, only the amount of the seat slide set by the slide amount setting means is detected. The slide control means controls the seat slide means to slide the vehicle seat, and the slide control means detects the opening of the door when the door opening degree detection means detects the opening of the door. It is preferable that the vehicle seat is started to slide by means. According to such a configuration, the sliding movement of the vehicle seat is started before the opened door is stopped and the door opening degree in the stopped state is detected by the door opening degree detecting means. So, for example, when the door is opened slowly, that is, even if it takes a long time for the door to stop after the opening of the door starts, prior to detecting the opening when the door stops By slidably moving the vehicle seat, it is possible to quickly improve the passenger's dismountability.

  Further, the getting-off start detecting means is such that the ignition switch is turned off from on and the buckle switch for detecting the connection between the tongue plate attached to the seat belt and the buckle fixed to the vehicle seat is turned off. If this is detected as the occupant's start of getting off, the slide control device for the vehicle seat is prevented from operating when the vehicle is running, and safety is ensured.

  According to the slide control device for a vehicle seat according to the present invention, when the door opening is large, that is, when it is easy to get off, the sliding amount of the vehicle seat is short and the door opening is small, that is, it is difficult to get off. Therefore, since the sliding amount of the vehicle seat can be controlled to be long, it is possible to improve the occupant's dismountability while preventing the vehicle seat from sliding more than necessary. is there.

  Hereinafter, an embodiment of a slide control device for a vehicle seat according to the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram for explaining a schematic configuration of a vehicle seat slide control mechanism executed by the vehicle seat slide control device according to the present embodiment.

  As shown in FIG. 1A, the vehicle seat slide control device of the present invention moves the vehicle seat 3 to the rear of the vehicle 1 when it detects that the door 2 provided in the vehicle 1 is opened. By sliding the vehicle to the left, the gap such as the foot space for the passenger to get off is widened to improve the getting-off property. In particular, the vehicle seat slide control device according to the present invention is configured such that the amount of sliding when the vehicle seat 3 is slid rearward of the vehicle 1 is variable according to the degree of opening of the opened door 2. It is. In this case, the vehicle seat 3 provided in the vehicle 1 includes a seat cushion 3a serving as a seating portion for the occupant, a seat back 3b serving as a seat back portion of the occupant and tiltable with respect to the seat cushion 3a, and the seat back 3b. The headrest 3c which is assembled | attached to the top part and receives a passenger | crew's rear head is provided.

  As shown in FIG. 1B, the vehicle seat 3 is slid in the front-rear direction of the vehicle 1 along the seat rail 4 fixed on the floor F of the vehicle 1. The slide motor 5 is provided, and by driving the slide motor 5, the vehicle seat 3 can be slid along the seat rail 4 in the front-rear direction of the vehicle 1.

  FIG. 2 is a block diagram showing a schematic configuration of the slide control device 10 for the vehicle seat 3. The slide motor 5 provided on the vehicle seat 3 is connected to the control unit 11 and is driven by a drive instruction from the control unit 11. In this case, the rotational speed of the driven slide motor 5 is detected by the rotational speed detection sensor 6 and the detection result is output to the control unit 11.

  The control unit 11 is connected to a door opening detection sensor 12, a buckle SW (buckle switch) 13, an ignition SW (ignition switch) 14, a shift lever SW (shift lever switch) 15, a vehicle ECU 16, and the like.

  The door opening degree detection sensor 12 is provided at the hinge portion 2a (see FIG. 1A) of the door 2, and detects and controls the opening of the door 2 and the angle (opening) of the opened door 2. The detection result is output to the unit 11.

  The buckle SW 13 is provided on the buckle 7 (see FIG. 1) fixed to the vehicle seat 3, and is turned on and removed when the tongue plate 9 attached to the front end of the seat belt 8 is inserted into the buckle 7. In this state, it is turned off and the connection between the buckle 7 and the tongue plate 9 is detected and the detection result is output to the control unit 11.

  The ignition SW 14 is provided in an ignition key cylinder provided in the vehicle 1 and is turned on when the ignition key is inserted into the ignition key cylinder and turned off when the ignition key is removed, or detects the ignition key insertion / removal state, or The on / off state of the engine provided in the vehicle 1 is detected and the detection result is output to the control unit 11.

  The shift lever SW15 is provided when the vehicle 1 includes an automatic transmission. The shift lever SW15 detects that the shift lever of the automatic transmission is set to the parking position, and outputs a detection result to the control unit 11.

  The control unit 11 to which the door opening degree detection sensor 12, the buckle SW13, the ignition SW14 and the like are connected includes a control unit 17, a memory 18, and a slide amount detection unit 19.

  The control unit 17 determines whether or not the ignition key has been removed or whether or not the engine has been turned off based on the output signal from the ignition SW 14, and further the tongue plate 9 of the seat belt 8 buckles according to the output signal from the buckle SW13. It is determined whether or not it has been removed from 7. In this case, when the vehicle 1 includes an automatic transmission, it is determined whether or not the shift lever of the automatic transmission is set to the parking position based on an output signal from the shift lever SW15. Further, the control unit 17 determines whether or not the door 2 is opened based on an output signal from the door opening degree detection sensor 12, and the opening degree (angle) of the door 2 opened by the door opening degree detection sensor 12. Let the detection occur.

  The memory 18 stores a set value for sliding control of the vehicle seat 3. For example, the memory 18 slides when the vehicle seat 3 is slid rearward according to the opening (angle) A of the door 2 detected by the door opening detection sensor 12 as shown in FIG. A quantity B is set. Specifically, the sliding amount B is 60 mm when the opening A of the door 2 detected by the door opening detection sensor 12 is 21 to 40 degrees, and the sliding amount B is 41 to 60 degrees. Is 40 mm and 61 degrees or more, the slide amount B is individually set corresponding to a predetermined range of the opening A of the door 2 such that the slide amount B is 20 mm. In this case, the memory 18 stores the position information of the rearmost position (non-retractable position) of the vehicle seat 3. For example, when the opening (angle) A of the door 2 is 0 to 20 degrees, As it is difficult to get off, the sliding amount (maximum) of the length from the position of the vehicle seat 3 before the sliding movement to the rearmost position can be set as appropriate.

  In the slide amount detection unit 19, the motor rotation number information of the slide motor 5 detected by the rotation number detection sensor 6 is calculated, the slide amount of the vehicle seat 3 slid and moved by the slide motor 5 is calculated, and the control unit The calculation result is output to 17.

  Next, the flow of the slide control by the slide control device 10 for the vehicle seat 3 described above will be described with reference to the flowchart shown in FIG.

  As shown in the figure, first, in step S1, the control unit 17 provided in the control unit 11 determines whether or not the ignition key is removed from the key cylinder or the engine is turned off by an output signal from the ignition SW. . If the determination is affirmed because the ignition key is removed from the key cylinder or the engine is turned off (S1 (Yes)), the process proceeds to step S2. In step S <b> 2, the control unit 17 determines whether or not the tongue plate 9 of the seat belt 8 has been removed from the buckle 7 based on the output signal from the buckle SW <b> 13. If it is affirmed that the tongue plate 9 of the seat belt 8 has been removed from the buckle 7 (S2 (Yes)), it is determined that the occupant start of getting off is detected, and the process proceeds to step S3.

  In step S <b> 3, the control unit 17 determines whether or not the door 2 is opened based on an output signal from the door opening degree detection sensor 12. When the door 2 is opened and the determination is affirmative (S3 (Yes)), the process proceeds to step S4. In step S4, the control unit 17 drives the slide motor 5 to start the rearward sliding of the vehicle seat 3, and proceeds to step S5.

  In step S5, the control unit 17 determines whether or not the vehicle seat 3 is at the rearmost position (retractable position), that is, whether or not the vehicle seat 3 is already in a position in which it cannot slide any further backward. To do. If the determination that the vehicle seat 3 is at the rearmost position is affirmative (S5 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the slide movement of the vehicle seat 3 is stopped. The process is terminated.

  Further, when the determination is made that the vehicle seat 3 is not the rearmost position (S5 (No)), the control unit 17 proceeds to step S6. In step S <b> 6, the control unit 17 stops when the opening (angle) of the door 2 changes due to the opening operation of the door 2 by the output signal from the door opening detection sensor 12, that is, the opened door 2 stops. Further, it is determined whether or not one second or more has passed in the stopped state. If the determination is negative (S6 (No)), that is, if the door 2 is still open, the process returns to step S5, and the slide motor 5 continues the rearward sliding movement of the vehicle seat 3. At this time, if the vehicle seat 3 has reached the rearmost position, the determination is affirmed that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15 and slides. The driving of the motor 5 is stopped, the sliding movement of the vehicle seat 3 is stopped, and the process is terminated.

  Further, when the determination is affirmed that the door 2 has been in a stopped state for 1 second or longer (S6 (Yes)), that is, when the opening operation of the door 2 is stopped, the control unit 17 proceeds to step S7. . In step S <b> 7, the control unit 17 determines whether or not the opening degree of the door 2 in a stopped state is within 20 degrees based on an output signal from the door opening degree detection sensor 12. When the determination is affirmed that the opening degree of the door 2 is within 20 degrees (S7 (Yes)), the control unit 17 returns to step S5 and causes the slide motor 5 to slide the vehicle seat 3 backward. Let it continue. Also at this time, when the vehicle seat 3 has reached the rearmost position, the determination is affirmed that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15. The drive of the slide motor 5 is stopped, the slide movement of the vehicle seat 3 is stopped, and the process is terminated.

  And control part 17 will shift to Step S8, if a judgment is denied (S7 (No)) that the opening of door 2 is larger than 20 degrees. In step S8, the control part 17 determines whether the opening degree of the door 2 is in the range of 21-40 degree | times. If the determination is affirmed that the opening degree of the door 2 is within a range of 21 to 40 degrees (S8 (Yes)), the process proceeds to step S9. In step S9, the controller 17 determines whether or not the slide amount (slide length) of the vehicle seat 3 that has been slid and detected by the slide amount detector 19 exceeds 60 mm. If the determination is affirmed that the sliding amount of the vehicle seat 3 that has been slid exceeds 60 mm (S9 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the vehicle seat 3 The slide movement is stopped and the process is terminated.

  If the determination is negative because the sliding amount of the slidable vehicle seat 3 does not exceed 60 mm (S9 (No)), the process returns to step S5, and the slide motor 5 slides the vehicle seat 3 backward. Let the move continue. Also at this time, when the vehicle seat 3 has reached the rearmost position, the determination is denied that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15. The drive of the slide motor 5 is stopped, the slide movement of the vehicle seat 3 is stopped, and the process is terminated.

  Next, in step S8, if the determination is negative because the opening degree of the door 2 is not within the range of 21 to 40 degrees (S8 (No)), the process proceeds to step S10. In step S10, the control part 17 determines whether the opening degree of the door 2 is in the range of 41-60 degrees. When the determination is affirmed that the opening degree of the door 2 is within the range of 41 to 60 degrees (S10 (Yes)), the process proceeds to step S11. In step S11, the control unit 17 determines whether or not the slide amount (slide length) of the vehicle seat 3 that has been slid and detected by the slide amount detection unit 19 exceeds 40 mm. If the determination is affirmative that the slide amount of the vehicle seat 3 that has been slid exceeds 40 mm (S11 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the vehicle seat 3 The slide movement is stopped and the process is terminated.

  If the determination is negative because the sliding amount of the slidable vehicle seat 3 does not exceed 40 mm (S11 (No)), the process returns to step S5, and the slide motor 5 slides the vehicle seat 3 backward. Let the move continue. Also at this time, when the vehicle seat 3 has reached the rearmost position, the determination is affirmed that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15. The drive of the slide motor 5 is stopped, the slide movement of the vehicle seat 3 is stopped, and the process is terminated.

  Next, in step S10, if the determination is negative (S10 (No)) because the opening degree of the door 2 is not within the range of 41 to 60 degrees, the process proceeds to step S12. In step S12, the control part 17 determines whether the opening degree of the door 2 is 60 degree | times or more. If the determination is affirmed that the opening degree of the door 2 is 60 degrees or more (S12 (Yes)), the process proceeds to step S14. In step S14, the control unit 17 determines whether or not the slide amount (slide length) of the vehicle seat 3 that has been slid and detected by the slide amount detection unit 19 exceeds 20 mm. If the determination is affirmed that the sliding amount of the vehicle seat 3 that has been slid exceeds 20 mm (S14 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the vehicle seat 3 The slide movement is stopped and the process is terminated.

  If the determination is negative because the sliding amount of the slidable vehicle seat 3 does not exceed 20 mm (S14 (No)), the process returns to step S5, and the slide motor 5 slides the vehicle seat 3 backward. Let the move continue. Also at this time, when the vehicle seat 3 has reached the rearmost position, the determination is affirmed that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15. The drive of the slide motor 5 is stopped, the slide movement of the vehicle seat 3 is stopped, and the process is terminated.

  Next, when the determination is affirmed in Step S12 that the opening degree of the door 2 is 60 degrees or more (S12 (No)), the process proceeds to Step S13. In step S <b> 13, the control unit 17 determines whether the opening degree of the door 2 is the maximum angle, that is, the door 2 is not opened any more, based on the output signal from the door opening degree detection sensor 12. If the determination is affirmed that the opening degree of the door 2 is the maximum angle (S13 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the slide movement of the vehicle seat 3 is stopped. The process is terminated.

  In Step S13, if the determination is negative because the opening degree of the door 2 is not the maximum angle (S13 (No)), the process proceeds to Step S14 as in Step S12 (Yes). In step S14, the control unit 17 determines whether or not the slide amount (slide length) of the vehicle seat 3 that has been slid and detected by the slide amount detection unit 19 exceeds 20 mm. If the determination is affirmed that the sliding amount of the vehicle seat 3 that has been slid exceeds 20 mm (S14 (Yes)), the process proceeds to step S15, the drive of the slide motor 5 is stopped, and the vehicle seat 3 The slide movement is stopped and the process is terminated.

  If the determination is negative because the sliding amount of the slidable vehicle seat 3 does not exceed 20 mm (S13 (No)), the process returns to step S5, and the slide motor 5 slides the vehicle seat 3 backward. Let the move continue. Also at this time, when the vehicle seat 3 has reached the rearmost position, the determination is affirmed that the vehicle seat 3 is the rearmost position (S5 (Yes)), and the process proceeds to step S15. The drive of the slide motor 5 is stopped, the slide movement of the vehicle seat 3 is stopped, and the process is terminated.

  Next, the temporal flow of various controls by the slide control device 10 for the vehicle seat 3 described above will be described with reference to timing charts shown in FIGS.

  FIG. 5 shows a timing chart when the opening degree of the opened door 2 is, for example, 21 degrees to less than the maximum angle. As shown in the figure, the output signal from the ignition SW 14 changes from on to off, and then the output signal from the buckle SW 13 changes from on to off, whereby the start of the passenger getting off is detected by the control unit 17. . Thereafter, when the door 2 is opened, the output signal from the door opening detection sensor 12 changes from OFF to ON, and at the same time, the control unit 17 drives the slide motor 5 to move the rear of the vehicle seat 3. The slide movement to is started. Thereafter, when the opening operation of the door 2 is stopped, the output signal from the door opening degree detection sensor 12 changes from on to off, and the opening degree of the door 2 at that time is detected and the detection result is output to the control unit 17. The

  The controller 17 detects the amount of sliding (60 mm, 40 mm) set in the memory 18 according to the opening (21 degrees to less than the maximum angle) of the door 2 detected by the door opening detection sensor 12 and the size of the opening. , 20 mm), the slide motor 5 is driven and controlled so as to slide the vehicle seat 3 by the slide amount. Then, when the vehicle seat 3 slides by the set slide amount, the control unit 17 stops driving the slide motor 5 and stops the slide movement of the vehicle seat 3.

  Thus, when the door 2 is fully opened (when the opening degree of the door 2 is large), the vehicle seat 3 is slid at an early stage by sliding the vehicle seat 3 with a corresponding short slide amount. When the door 2 cannot be opened sufficiently (when the opening of the door 2 is small), the vehicle seat 3 is slid with a corresponding long slide amount, It is possible to improve the dismountability. That is, when the opening degree of the door 2 is large, that is, when it is easy to get off, the sliding amount of the vehicle seat 3 is set short, and when the opening degree of the door 2 is small, that is, when it is difficult to get off, the vehicle seat 3 By setting the slide amount longer, it is possible to improve the dismountability and to eliminate the troublesomeness when the vehicle seat 3 slides more than necessary.

  FIG. 6 shows a timing chart when the opening (angle) of the opened door 2 is the maximum angle. As shown in the figure, the output signal from the ignition SW 14 changes from on to off, and then the output signal from the buckle SW 13 changes from on to off, and then the door 2 is opened, thereby opening the door opening detection sensor. At substantially the same time as the output signal from 12 changes from off to on, the control unit 17 drives the slide motor 5 to start the rearward movement of the vehicle seat 3. Thereafter, when the opening operation of the door 2 is stopped, the output signal from the door opening degree detection sensor 12 changes from on to off, and the opening degree of the door 2 at this time, in this case, the maximum angle is detected and the control unit 17 is detected. The detection result is output at.

  In this case, since the opening degree of the door 2 detected by the door opening degree detection sensor 12 is the maximum angle, the control unit 17 slides almost simultaneously with the detection result from the door opening degree detection sensor 12 being input. The driving of the motor 5 is stopped, and the sliding movement of the vehicle seat 3 is stopped. The sliding amount of the vehicle seat 3 at this time is obtained by multiplying the speed at which the vehicle seat 3 slides by the time from when the output signal from the door opening degree detection sensor 12 is turned on to when it is turned off. It becomes. When the door 2 is opened at the maximum angle as described above, it is assumed that the occupant has a good dismounting property, and the sliding movement of the vehicle seat 3 is stopped almost simultaneously with the door 2 being opened at the maximum angle. Therefore, the vehicle seat 3 is prevented from sliding more than necessary. As a result, even in a situation where a door such as a conventional vehicle seat slide control device is largely opened and it is easy to get off, the vehicle seat must wait until the vehicle seat is slid by a predetermined amount and stopped. The troublesome slide movement more than necessary is eliminated.

  FIG. 7 shows a timing chart when the door 2 is slowly opened (the door opening speed is slow). As a situation where the door 2 is slowly opened, for example, there are other vehicles, walls, and other injuries in the immediate vicinity of the door 2 so that the door 2 to be opened does not come into contact with these injuries. Can be mentioned. As shown in the figure, the output signal from the ignition SW 14 changes from on to off, and then the output signal from the buckle SW 13 changes from on to off, and then the door 2 is opened, thereby opening the door opening detection sensor. At substantially the same time as the output signal from 12 changes from off to on, the control unit 17 drives the slide motor 5 to start the rearward movement of the vehicle seat 3. Thereafter, since the opening operation of the door 2 is slow, the sliding movement of the vehicle seat 3 is continued while the opening operation of the door 2 is continued.

  As shown in the drawing, the vehicle seat 3 that has been slid before the opening operation of the door 2 stops, that is, before the output signal from the door opening detection sensor 12 changes from on to off, is the rearmost end. When the position is reached, the drive of the slide motor 5 is stopped, and the slide movement of the vehicle seat 3 is stopped. In such a situation where there are obstacles such as other vehicles or walls in the immediate vicinity of the door 2 and the door 2 is slowly opened in order to prevent the obstacle 2 from coming into contact with the door 2 to be opened. However, since the vehicle seat 3 is slid and moved by an appropriate slide amount, the passenger can get off the vehicle.

  The above-described slide control device 10 for the vehicle seat 3 is a door that opens the sliding amount of the vehicle seat 3 that is retracted toward the rear of the vehicle 1 in order to expand the passenger's foot space when the passenger gets off. 2 is set based on the opening degree of 2, that is, the sliding amount for moving the vehicle seat 3 backward is variable according to the opening degree of the door 2.

  Thereby, for example, when the door 2 is sufficiently opened (when the opening degree of the door 2 is large), the vehicle seat 3 can be quickly moved by sliding the vehicle seat 3 with a corresponding short sliding amount. When the door 2 cannot be opened sufficiently (when the opening degree of the door 2 is small), the vehicle seat 3 is slid with a long sliding amount corresponding to stopping the sliding movement to improve the dismountability. Thus, it is possible to improve the dismountability.

  That is, when the opening degree of the door 2 is large, that is, when it is easy to get off, the sliding amount of the vehicle seat 3 is set short, and when the opening degree of the door 2 is small, that is, when it is difficult to get off, the vehicle seat 3 By setting the slide amount to be long, it is possible to eliminate the troublesomeness when the vehicle seat is slid more than necessary, while securing a good dismounting property.

  In this case, the slide control device 10 for the vehicle seat 3 is configured to start the slide of the vehicle seat 3 by the slide motor 5 when the door opening degree detecting means 12 detects the opening of the door 2, that is, the opening. The door 2 is stopped, and the sliding movement of the vehicle seat 3 is started before the door 2 in the stopped state is detected by the door opening detecting means 12. Thereby, for example, when the door 2 is opened slowly, that is, when the time from the start of opening the door 2 to the stop of the door 2 is long, the opening degree detection when the door 2 stops is detected. Prior to this, since the vehicle seat 3 is slid and moved, the occupant's ability to get off can be quickly improved.

  As mentioned above, although embodiment of the slide control apparatus of the vehicle seat which concerns on this invention was described, this invention is not limited to such embodiment at all, In the range which does not deviate from the summary of this invention, it is various aspects. Of course, it can be implemented.

  For example, in the slide control device 10 described above, the configuration in which the ignition SW 14 is switched from on to off and the buckle SW 13 is switched from on to off is detected as the start of the passenger getting off, but the shift lever SW 15 is automatically operated. When it is detected that the shift lever of the transmission is set to the parking position, or further, the fact that the parking brake is turned on may be added as the start of getting off the passenger.
