A release switch 43 is a switch corresponding to the on operation and the off operation, respectively. is there.

FIG. 2 is a flowchart of a process performed by the braking unit 2 of the passenger seat control apparatus according to one embodiment of the present invention. 3A and 3B are side views showing the seat position and the backrest angle of the passenger seat, wherein FIG. 3A shows a normal state, and FIG. 3B shows a state of getting on and off. Hereinafter, description will be made with reference to the drawings. In this embodiment, the operation of the operation switch 41, the operation of the remote control operation switch 42, and the opening / closing state of the front passenger's seat side door are detected, and the seat position and the backrest angle of the front passenger seat are set so that getting on and off the rear seat becomes easy. Is controlled. This process is repeatedly executed with the ACC of the vehicle turned on (or the engine is started).

In step S11, it is determined whether or not the release switch is off. If the release switch is off, the process proceeds to step S12. If the release switch is on, the process ends. That is, it is determined whether the passenger seat control device is in an operable state or an inoperable state, and is determined based on the state of the release switch 43 that is manually operated. In the ON state, the operation of the passenger seat control device is canceled (operation disabled).

In step S12, it is determined whether or not the operation switch has been turned on. If the operation switch has been turned on, the process proceeds to step S13. If the operation switch has not been turned on, the process proceeds to step S17. In other words, control the seat position and backrest angle of the front passenger seat (moving forward / tilting forward)
It is determined whether or not to perform the operation, based on the operation state of the operation switch 41 or the remote control operation switch 42. still,
When the operation switch 41 or the like is turned on, the instruction is to move the seat 51 to the forefront, and to tilt the backrest 52 to the foremost position. When the operation is turned off (when the operation switch 41 or the like is operated again), the seat is operated. It is an instruction to operate the back 51 (the original position) and the backrest 52 backward (the original angle).

In step S13, it is determined whether or not there is an occupant in the front passenger seat. If there is an occupant in the front passenger seat, the process is terminated. If there is no occupant in the front passenger seat, the process proceeds to step S14. That is, if the occupant is in the passenger seat (seat 51) (sitting), it is dangerous to change the positions and angles of the seat 51 and the backrest 52 of the passenger seat, so that the seat position and the backrest angle should not be changed. The presence / absence of an occupant in the passenger seat (seat 51) is determined by the passenger seat occupant detection sensor 11
It is determined based on the detection state of. If the occupant sitting on the front passenger seat gets off when getting on or off the rear seat (the passenger seat occupant detection sensor 11 changes from ON to OFF), it is dangerous to proceed to the next step S14 immediately. There is a safe time after the passenger in the passenger seat gets off (for example,
After 5 seconds, the seat 51 is moved forward or the backrest 52 is tilted forward.

In step S14, the seat is moved to the forefront, and at the same time, the backrest is tilted forward, and the process proceeds to step S15. That is, the control unit 2 causes the seat position adjustment actuator 31 to move the seat 51 to the forefront, and at the same time, outputs a signal to the backrest angle adjustment actuator 32 to tilt the backrest 52 forward. At this time, the current seat position and the backrest angle are detected by the seat position detection sensor 13 and the backrest angle detection sensor 14 and stored in the memory in the control unit 2 (the original position and angle are stored). As the seat 51 moves forward, the position of the seat 51 is detected by the seat position detection sensor 13 as needed, and stops when it reaches a predetermined position (a limit switch provided at the forefront position). Further, the backrest angle is detected by the backrest angle detection sensor 14 at any time in accordance with the forward leaning operation of the backrest 52, and stops when a predetermined angle (a limit switch provided at the most forwardly inclined angle) is reached (see FIG. 3B). ). This operation widens the opening behind the passenger seat, and facilitates getting on and off the rear seat. In addition, the getting-in / out operation to the rear seat is performed between step S14 and step S15.

In step S15, it is determined whether or not the operation switch has been turned off. If the operation switch has been turned off, the process proceeds to step S16. If the operation switch has not been turned off, the process proceeds to step S24. That is, it is determined whether or not to control the seat position and the backrest angle of the passenger seat to the original state, and the determination is made based on the operation state of the operation switch 41 or the remote control operation switch 42.
When the operation switch 41 or the like is turned off, the seat 5 is turned off.
The instruction is to move the backrest 1 backward to the original position and to tilt the backrest 52 backward to the original angle.

In step S16, the seat 51 is moved rearward to the original position, and at the same time, the backrest 52 is tilted backward to the original angle to complete the processing. That is, the control unit 2 outputs a signal to the seat position adjustment actuator 31 to move the seat 51 backward to the original position, and at the same time, to cause the back angle adjustment actuator 32 to tilt the backrest 52 backward to the original angle. The original position and angle are detected in step S14, and the position data and angle data stored in the memory in the control unit 2 are used. As the seat 51 moves backward, the position of the seat 51 is detected by the seat position detection sensor 13 as needed, and stops when the seat 51 reaches a predetermined position (memory value). Further, the backrest angle is detected by the backrest angle detection sensor 14 at any time in accordance with the backward tilt operation of the backrest 52, and stops when the backrest angle comes to a predetermined position (memory value) (see FIG. 3A). By this operation, the front of the passenger seat is widened, and riding on the passenger seat becomes easy.

In step S17, it is determined whether or not the passenger side door is open. If the passenger side door is open, the process proceeds to step S18, where the passenger side door is opened. If not, the process ends. In other words, it determines whether or not to control the seat position and the backrest angle of the passenger seat. When the door on the passenger seat side is opened, the occupant (either the passenger on the passenger seat or the rear seat occupant or both) gets on and off. It is determined that there is a possibility. The open state of the passenger side door is determined based on the detection result of the passenger side door open / close detection sensor 12.

In step S18, the process waits for a predetermined time t1 and proceeds to step S19. In step S19, it is determined whether or not the occupant in the passenger seat has changed from the presence to the absence. When the occupant changes from the presence to the absence, the process proceeds to step S20.
Move to 22. That is, a change in the passenger seat occupant from the existing state to the non-present state within the predetermined time t1 means that the passenger in the front passenger seat has got off. The fact that the occupant in the passenger seat does not change from the presence to the absence even after the predetermined time t1 has elapsed means that there is no occupant in the passenger seat from the beginning (the occupant is empty to nothing), or the occupant was originally in the passenger seat but did not descend. (The occupant is in the state of existence).

In step S20, the process waits for a predetermined time t2 and proceeds to step S21. In step S21, it is determined whether or not the passenger side door is open. If the door is open, the process proceeds to step S14. If not, the process is terminated (closed). In other words, even if a long time has passed since the passenger in the passenger seat got off (predetermined time t2 or more), if the passenger side door is kept open, it is inferred that the passenger will get on and off the rear seat, and It is necessary to move forward and tilt the backrest 52 forward. It is presumed that the closing of the door on the front passenger seat within a short time (less than the predetermined time t2) after the passenger on the passenger seat got off, only the passenger on the passenger seat got off, and there was no getting on / off to the rear seat. It is not necessary to move the seat 51 forward and tilt the backrest 52 forward.

In step S22, the process waits for a predetermined time t3 and proceeds to step S23. In step S23, it is determined whether or not the passenger seat occupant is in the presence state. If the passenger seat occupant is in the presence state, the process is terminated. If the passenger seat occupant is not in the presence state, the process proceeds to step S14. That is, the predetermined time t
The presence of the occupant in the passenger seat within 3 means that the occupant's occupancy has continued, or that the occupant has newly got on the passenger seat (changed from the absent state to the occupied state). . In any case, since the occupant is seated in the passenger seat, it is dangerous and the forward movement of the seat 51 and the forward leaning operation of the backrest 52 are not performed. Since the occupant in the passenger seat has changed from having or not having passed when the predetermined time t3 has elapsed, it is presumed that the occupant in the passenger seat has gotten down. Therefore, it is necessary to move the seat 51 forward and tilt the backrest 52 forward.

In step S24, it is determined whether or not the passenger side door is closed. If the door is closed, the process proceeds to step S16, and if not, the process is terminated. In other words, it is determined whether the seat position and the backrest angle of the passenger seat may be returned to the original state,
If the passenger's seat side door is closed, it can be determined that all the passengers (both the passenger seat and the rear seat) have entered and exited, so the seat 51 and the backrest 52 are in the original state (moving backward and leaning backward).
It is determined that it may be returned to. If the passenger side door is open, it can be determined that the occupants (passenger seat, rear seat) have not yet entered and exited, so the seat 51 and the backrest 5 can be determined.
Restoring 2 to its original state (moving backward / tilting backward) is suspended.

As described above, in this embodiment, it is possible to adjust the seat position and the backrest angle of the passenger seat only by operating the switch in the driver's seat, or by detecting that the passenger side door is opened. Therefore, getting in and out of the rear seat becomes smooth.

Although the present embodiment has been described with reference to a two-door type vehicle as an example, the present invention is not limited to this. For a four-door type vehicle, a passenger seat 5 is provided so that the passenger can easily get on and off the rear seat.
1 may be moved. In this case, sheet 51
Is changed from the opening / closing detection operation of the passenger side door to the opening / closing detection operation of the rear seat side door.
