The present invention relates to a vehicle seat drive control device, which can make the seat used by the elderly or disabled people move between a predetermined position in the vehicle interior and a position for getting on and off the vehicle.

Background technique

As shown in FIG. 15 , the seat driving device 100 described in Japanese Patent Application Laid-Open No. 2007-161010 can make a seat body 102 used as a passenger seat of a vehicle move up and down a vehicle door 104 from a predetermined position I in the vehicle interior. After turning left about 90°, move to the getting on and off position II outside the car from the getting on and off door 104.

A seat occupancy sensor (not shown) for detecting the presence or absence of a seated person is provided in the seat main body 102 . When the seat occupancy sensor does not detect an occupant, that is, when there is no occupant on the seat main body 102 (when the seat is empty), the seat driving device 100 can make the movement speed of the seat main body 102 faster than when someone is seated. faster. In this way, for example, when an elderly person boards the vehicle, the time required for the seat body 102 inside the vehicle to move to the getting on and off position II outside the vehicle can be shortened, thereby improving its practicability.

Contents of the invention

The technical problem to be solved by the invention

However, when the seat main body 102 is empty, all the driving operations of the seat driving device are driven at a high speed, which increases the load on the motor which is the driving source and wastes power consumption. Therefore, it is desired to be able to shorten the operating time of the seat body when the seat body is empty while suppressing wasteful power consumption of the motor.

Technical solutions adopted to solve technical problems

According to a feature of the present invention, the seat driving control device of the vehicle is provided with: a driving device for driving the seat main body to move between a predetermined position in the vehicle interior and a position for getting on and off the vehicle inside or outside the vehicle; an occupancy sensor for the absence of a seated person; and a control device for controlling the driving device. The control device controls the driving device so that when the seat occupancy sensor detects a seated person, the seat main body is driven by the driving device in a series of driving actions, and when the seat occupancy sensor does not detect a seated person, the driving device is omitted to perform the operation. The seat body is driven as part of a series of driving actions.

In the present invention, when the seat occupancy sensor does not detect an occupant, that is, when the seat body is empty, part of the driving action in the series of driving actions when the seat body is seated is omitted. Therefore, compared with when someone is seated on the seat body, when the seat body is empty, the movement of the seat body can be shortened between a predetermined position inside the vehicle interior and a position for getting on and off the vehicle outside. time, thereby improving the practicality of the vehicle seat.

Here, "omitting part of a series of driving actions" not only means omitting one of the various driving actions constituting the series of driving actions, but also includes shortening the driving distance of one driving action. In addition, the "seat body" includes a wheelchair and the like in addition to a seat body of a vehicle seat.

As shown in FIG. 4 , lift guides 57 are provided at outer positions of the left and right guide rails 41 in the rotating base 35 . The lift guide 57 is omitted in FIGS. 5 to 7 . The lift guide 57 supports the left and right outer link arms 52 of the four-bar linkage mechanism 51 from below. The lifting guide 57 can transform the forward motion or the backward motion of the lateral sliding base 44 and the four-bar linkage mechanism 51 into the downward or upward rotation motion of the four-bar linkage mechanism 51 .

As shown in FIGS. 6 and 7 , on the lift base 55 of the lift mechanism 50 , an inside-outside sliding mechanism 70 for moving the seat body 10 forward or backward relative to the lift base 55 is provided. As shown in Figure 3, the inner and outer sliding mechanism 70 is provided with: a seat base 75 supporting the seat body 10; a pair of left and right guide rails 74a fixed on the lower surface of the seat base 75; The slider 74b which slidably supports the guide rail 74a; and the drive part 76 which is a drive source of the inside-outside slide mechanism 70. The driving portion 76 is provided with: a rack 73 provided on the lower surface of the base 75 for the seat and parallel to the guide rail 74a; a pinion 72 provided on the elevating base 55 and meshed with the rack 73; 72 drives the motor 71 for rotation.

As shown in FIG. 1 , the seat body 10 is provided with a seat cushion 11 and a seat back 12 , and the frame of the seat cushion 11 is connected to the seat base 75 of the inner-outer slide mechanism 70 (see FIG. 3 etc.).

As shown in FIGS. 1 and 2 , a reclining mechanism 90 for adjusting the inclination of the seat back 12 relative to the seat cushion 11 is provided on the seat main body 10 . As shown in FIG. 2 , the reclining mechanism 90 is provided with: an externally toothed gear 92 provided on the frame side of the seat back 12 ; The internal gear 94; the tilt motor (not shown) that rotates the external gear 92; and the limit switch 96 that detects the origin of the tilt.

As shown in FIG. 1 , a seat occupancy sensor 80 is provided in the seat cushion 11 of the seat body 10 for receiving a load when a person sits on the seat body 10 to detect the presence or absence of a seated person. The seat body 10 is provided with a get-off switch (not shown) for driving the seat body 10 to get off and a get-on switch (not shown) for driving the seat body 10 to get on.

As shown in FIG. 1 , the vehicle seat S is provided with an ECU 60 (control device) for controlling the driving operation of the seat main body 10 by the seat driving device 200 . Electric signals output from the entry switch, exit switch, and seat occupancy sensor 80 are input to the ECU 60 (control device) of the vehicle. The ECU 60 controls the driving operation of the seat body 10 realized by the front and rear slide mechanism 20 , the swivel mechanism 30 , the lift mechanism 50 , the inside and outside slide mechanism 70 , and the reclining mechanism 90 constituting the seat driving device 200 according to the input electric signal.

Referring to FIGS. 8 to 13 , the driving operation of the seat main body 10 by the seat driving device 200 when a person is seated on the seat main body 10 will be described. When a person sits on the seat body 10 , the seating sensor 80 is turned on, and a signal is turned on from the seating sensor 80 to the input ECU 60 . When the seat occupancy sensor 80 is turned on, the seat main body 10 located in the vehicle interior is held at the original position (rear original position) (see timing I of FIGS. 8 and 13 ).

When moving the seat body 10 from the original position inside the vehicle to the getting on and off position outside the vehicle, the operator must open the door Dr of the vehicle C and then operate the getting off switch. The ECU 60 outputs a rotation signal to the rotation mechanism 30 by operating the getting off switch. The rotation mechanism 30 receives the rotation signal, and makes the seat body 10 turn left. When the seat main body 10 turns left at a certain angle (refer to the moment II of FIGS. 9 and 13 ), the ECU 60 outputs a forward sliding signal. During the continuous operation of the rotating mechanism 30 , the front and rear sliding mechanism 20 receives the forward sliding signal to make the front and rear sliding base 21 slide forward. That is, the seat main body 10 rotates leftward while sliding forward from the origin position (rotation slide operation). In this way, interference between the seat main body 10 and the center pillar P of the vehicle C can be avoided, as shown by the dashed-two dotted line in FIG. 10 .

After the seat body 10 starts to rotate and slide, as shown in FIG. 13 , the ECU 60 outputs a tilt signal. The tilt mechanism 90 receives the tilt signal, and tilts the seat back 12 of the seat body 10 backward at a certain angle. In this way, it is possible to prevent the head of the occupant from colliding with the roof panel of the vehicle. At a predetermined time during the rotation and sliding of the seat body 10 , the ECU 60 outputs a forward signal (down signal) to the lateral slide mechanism 40 of the lift mechanism 50 within a certain period of time. The slide lock of the seat main body 10 is released by advancing a certain distance by laterally sliding the base 44 . During the rotating and sliding process of the seat main body 10, as shown in FIG. 5, when the seat main body 10 rotates about 90° and faces the upper and lower vehicle doors D, the ECU 60 outputs an outward sliding signal to the inner and outer sliding mechanism 70 (referring to FIG. 13 Moment III). After the inner and outer sliding mechanism 70 receives the outward sliding signal, as shown in FIG. 6 , the seat main body 10 is moved forward relative to the lifting base 55 of the lifting mechanism 50 . That is, the seat body 10 moves from the doorway D to the outside of the vehicle (outward sliding operation).

After the seat main body 10 starts to slide outwards, at a predetermined moment, the rotating mechanism 30 and the front and rear sliding mechanism 20 stop, and the rotating and sliding is completed (see FIG. 10 ). At this time, the orientation of the seat body 10 is changed from the orientation facing the front of the vehicle to the orientation rotated by about 100°. After the seat body 10 completes the rotational sliding, at a predetermined timing, as shown in FIG. 13 , the ECU 60 outputs the tilt signal again. The tilt mechanism 90 receives the tilt signal, and tilts the seat back 12 of the seat body 10 backward at a certain angle. At a predetermined time during the outward sliding of the seat body 10 , the ECU 60 outputs a forward signal (down signal) to the lateral slide mechanism 40 of the lift mechanism 50 (see time IV in FIG. 13 ). The transverse sliding mechanism 40 receives the forward signal, and the transverse sliding base 44 moves the four-bar linkage mechanism 51 forward. As a result, as shown in FIG. 7, the four-bar linkage mechanism 51 rotates downward due to the elevating guide 57, and the seat body 10 advances together with the elevating base 55 and descends horizontally (see FIG. 11).

While the seat body 10 is descending, the ECU 60 outputs a reclining signal to the reclining mechanism 90 . The reclining mechanism 90 receives the reclining signal and operates to erect the seat back 12 of the seat body 10 at a certain angle. When the seat body 10 reaches the getting on and off position and completes the descent, the lifting mechanism 50 stops (moment V in FIGS. 12 and 13 ), and the reclining mechanism 90 makes the seat back 12 of the seat body 10 stand up to the original position again.

A series of driving actions of the seat driving device 200 are completed in the above manner. In addition, when moving the seat body 10 with a person on it from the getting on and off position to the vehicle interior, the getting on board switch is operated. When the getting-in switch is operated, the reverse operation is performed in reverse order, and the seat body 10 moves to the rear origin position in the vehicle interior.

Next, the driving operation of the seat driving device 200 when no one is seated on the seat body 10 (when the seat body 102 is empty) will be described mainly with reference to FIG. 14 . When the seat main body 102 is an empty seat, because there is no need to consider, for example, the interference of the seated person with the edge of the doorway D, the seat driving device 200 moves the seat main body 10 differently from the trajectory when someone is seated. .

When no one is seated on the seat body 10 , the seating sensor 80 is turned off, and an OFF signal is input from the seating sensor 80 to the ECU 60 . When the seat occupancy sensor 80 is OFF, the seat body 10 in the vehicle interior is held at the front origin position which is a predetermined distance ahead of the rear origin position. That is, the position of the seat body 10 in the vacant state is forward by a certain distance compared to when a person is seated.

When moving the seat body 10 from the front origin position inside the vehicle interior to the getting on and off position outside the vehicle, the operator must open the door Dr of the vehicle C and then operate the getting off switch. If the get off switch is operated, then as shown in Figure 14, the rotating mechanism 30 and the front and rear sliding mechanism 20 start working simultaneously, and the seat body 10 moves forward from the front origin position and rotates to the left (rotation and sliding action). Here, since the seat body 10 in the vacant state moves forward from the front origin position, the operation time of the front-rear slide mechanism 20 is shorter than that when a person is seated. At this time, the operation time of the rotation mechanism 30 which operates simultaneously with the front-back slide mechanism 20 is also shortened. The rotation angle of the empty seat body 10 is the same as when a person is seated. Therefore, when the seat body 10 is empty, the rotation speed of the rotation mechanism 30 becomes high.

At a predetermined timing during the rotation and sliding of the seat body 10 , as shown in FIG. 14 , the slide lock of the seat body 10 is released. During the rotating and sliding process of the seat body 10, when the seat body 10 is rotated about 90° to face the doorway D as shown in FIG. 5, the inner and outer sliding mechanism 70 works. Therefore, as shown in FIGS. 6 and 11 , the seat body 10 moves from the doorway D to the outside of the vehicle (sliding outward).

After the seat main body 10 starts to slide outward, the rotating mechanism 30 and the front and rear sliding mechanism 20 stop, and the rotating and sliding ends. During the outward sliding process of the seat main body 10, the action of the lifting mechanism 50 is started, and through the effects of the lateral sliding mechanism 40 and the four-bar linkage mechanism 51, the seat main body 10 moves forward while descending. When the seat body 10 reaches the getting on and off position, the elevating mechanism 50 stops. In addition, when the seat main body 10 is an empty seat, there is no need to consider the interference between the seated person's head and the vehicle roof, and therefore, the reclining mechanism 90 does not need to be operated.

Through the above manner, a series of driving actions of the seat driving device 200 are completed. In addition, when moving the seat body 10 in the vacant state from the getting on and off position outside the vehicle to the inside of the vehicle, the operator operates the getting on switch. When the getting-in switch is operated, actions in the opposite direction to the above are performed in the reverse order, and the seat body 10 moves to the front origin position in the vehicle interior.

As mentioned above, the seat driving control device of the vehicle is provided with: the seat driving device 200 that drives the seat body 10 between a predetermined position in the vehicle interior and the position of getting on and off the vehicle inside or outside the vehicle; a seat occupant sensor 80 ; and an ECU 60 (control device) that controls the seat driving device 200 . The ECU 60 controls the seat driving device 200 so that when the seat occupancy sensor 80 detects an occupant, the seat main body 10 is driven through a series of driving actions by the seat occupancy device 200 , and when the occupant sensor 80 does not detect an occupant. When seated, the seat main body 10 is driven by the seat driving device 200 after omitting part of a series of driving operations.

In this way, when the seat occupancy sensor 80 does not detect a seated person, that is, when the seat body 10 is empty, part of the driving operation in the series of driving operations when the seat body 10 is seated is omitted. Therefore, when the seat main body 10 is an empty seat, compared with when someone is seated in the seat main body 10, the time required for moving the seat main body 10 between a predetermined position in the vehicle interior and a getting on and off position outside the vehicle can be shortened. action time. Therefore, the usability of the vehicle seat S can be improved. Also, these omitted driving actions can correspondingly reduce the power consumption of the driving motor 24a.

The seat driving device 200 is provided with a front-back slide mechanism 20 for sliding the seat body 10 from a predetermined origin position in the front-back direction of the vehicle. The ECU 60 controls the front-back slide mechanism 20 so that the front-back slide amount of the seat body 10 when no occupant is detected is smaller than the front-back slide amount of the seat body 10 when a seat occupant is detected. Therefore, the sliding time when the seat body 10 is empty can be shortened, and the power consumption of the drive motor 24a can be suppressed. The ECU 60 controls the front-rear sliding mechanism 20 so that the origin position when no seat occupant is detected is shifted in the vehicle front-rear direction from the origin position when a seat occupant is detected, thereby realizing the control to change the sliding amount.

The seat driving device 200 is provided with a rotation mechanism 30 that horizontally rotates the seat main body 10 between facing the front of the vehicle and facing the lateral direction of the vehicle. The ECU 60 controls the rotation mechanism 30 so that the rotation speed of the seat body 10 driven by the rotation mechanism 30 is faster when no occupant is detected than that when a occupant is detected. Therefore, the rotation time of the seat main body 10 when the seat main body 10 is empty can be shortened. Here, the rotation angle of the seat body 10 is set to be the same regardless of whether the seat body 10 is empty or when someone is seated. Therefore, even if the rotation speed of the seat body 10 is increased when the seat body 10 is empty, wasteful power consumption of the rotary motor 32m can be suppressed.

The seat driving device 200 is provided with a reclining mechanism 90 for adjusting the reclining angle of the driving seat back relative to the seat cushion of the seat main body 10 . The ECU 60 controls the seat driving device 200 so that when the seat occupancy sensor 80 detects an occupant, the reclining mechanism 90 operates as part of a series of driving operations, and when the occupancy sensor 80 does not detect an occupant, The operation of the tilt mechanism 90 is omitted. Thus, since the operation of the reclining mechanism 90 is omitted when the seat body 10 is empty, the time for the seat driving device 200 to drive the reclining mechanism 90 can be shortened and power consumption of the motor can be suppressed.

Although the embodiments of the present invention have been described above with reference to the above structures, it will be apparent to those skilled in the art that various substitutions, improvements and changes can be made without departing from the purpose of the present invention. Therefore, the mode of the present invention may include all substitutions, improvements and changes made without departing from the spirit and purpose of the appended claims. For example, the mode of the present invention is not limited to the above-mentioned specific structure, and the following changes can be made.

The seat driving device 200 controlled by the ECU 60 does not necessarily include the lift mechanism 50 and the reclining mechanism 90 like in the present embodiment. For example, the seat driving device 200 may not include the lifting mechanism 50 , or may place the seat body 10 in a vehicle compartment where the seat body 10 gets on and off, or may not include the tilting mechanism 90 .

The present invention can also be applied to a vehicle seat having a front-rear sliding mechanism 20, a rotating mechanism 30, a tilting mechanism for tilting the seat body 10 forward or backward, and the like.

The vehicle seat S may be used as a driver's seat, for example, in addition to the vehicle passenger's seat as in the present embodiment.

The seat driving device 200 may be used as a device for driving the seat body of the vehicle seat S, for example, as a wheelchair (seat body) for raising and lowering the wheelchair (seat body) from the rear opening of the van, as in the present embodiment. Lifter (seat drive unit).
