JP 2021-95085 A

In recent years, in such vehicle seat control devices, it has been considered to provide the operating unit on an operating terminal that is detachable from the seat. The operating terminal is provided so as to be capable of wireless communication with the seat ECU, and outputs operating signals to the seat ECU that drive the slide drive unit and the like. In this case, the occupant can operate the seat using the operating terminal even if they cannot reach the armrest.

In this case, however, the following problems may occur. That is, if an occupant takes an operating terminal outside the vehicle and operates the vehicle seat, the seat may be operated without being able to see what is happening inside the vehicle. As a result, there is a risk of the seat interfering with luggage or other items placed on the floor of the vehicle, causing inconvenience.

A control system for a vehicle seat device to solve the above problem includes a seat device including a seat configured to be movable within a vehicle cabin and a motor for driving the seat, a control device having a control unit for controlling the driving of the motor, and an operation terminal that is capable of wireless communication with the control unit and outputs an operation signal to the control unit for driving the motor. The control device or the control unit includes an estimation unit that estimates whether the operation terminal is located outside the vehicle, and when the estimation unit estimates that the operation terminal is located outside the vehicle, the operation terminal or the control unit prohibits the operation terminal from operating the seat device.

According to this configuration, when the estimation unit estimates that the operating terminal is outside the vehicle, the operation terminal is prohibited from operating the seat via the operating terminal or the control unit. Therefore, it is possible to prevent the seat from being operated in a situation where the state inside the vehicle interior is unknown.

In the above-mentioned control system for a vehicle seat device, the control device includes an operation terminal detection unit that detects whether the operation terminal is present at a predetermined position in the vehicle cabin, a seating detection unit that detects whether an occupant is seated in the seat, and a door detection unit that detects the open/closed state of a door that opens and closes an entrance through which the occupant seated in the seat gets in and out. It is preferable that the operation terminal or the control unit prohibits the operation terminal from operating the seat device when the operation terminal detection unit detects that the operation terminal is not present at the predetermined position, the seating detection unit detects that an occupant is not seated in the seat, and the door detection unit detects that the door is open.

When an occupant moves from inside the vehicle to outside the vehicle while holding the operating device, all three conditions are met: the operating device is not in the designated position inside the vehicle, the occupant is not seated in the seat, and the door is open.

According to the above configuration, when the operation terminal detection unit, the seating detection unit, and the door detection unit detect that all three of the above conditions are met, the operation terminal or the control unit prohibits the operation of the seat from being performed by the operation terminal. Therefore, it is possible to estimate with high accuracy that the operation terminal is outside the vehicle.

In the above-mentioned vehicle seat device control system, it is preferable that a charging device for charging the operation terminal is provided in the vehicle interior, and the operation terminal detection unit detects that the operation terminal is present at the predetermined position when the operation terminal is being charged by the charging device.

Because the operating terminal can communicate wirelessly with the control unit, for example, the operating terminal detection unit can be configured to detect whether the operating terminal is present inside the vehicle cabin based on the radio wave strength of the operating terminal received by the control unit. In this case, however, the following problems may occur. That is, even though the operating terminal is present inside the vehicle cabin, the radio wave strength may be lower than a threshold value, causing the operating terminal to be detected as being outside the vehicle, a so-called false detection. In this case, an inconvenience may occur in which the occupant cannot operate the operating terminal even though the operating terminal is present inside the vehicle cabin.

In this regard, according to the above configuration, the presence of the operating terminal in a predetermined position within the vehicle cabin is detected based on information that the operating terminal is being charged by a charging device. Therefore, at least when the operating terminal is being charged by a charging device, the operating terminal is not erroneously detected as being outside the vehicle when it is actually inside the vehicle cabin. Therefore, the occurrence of the above-mentioned inconvenience can be avoided.

In the above-mentioned vehicle seat device control system, the seat has a seat cushion and a pressure-sensitive seating sensor provided on the seat cushion, the seat is provided with a buckle to which a tongue of a seat belt that restrains an occupant seated on the seat can be attached and detached, the buckle is provided with a buckle switch that detects whether the tongue is connected to the buckle, and the seating detection unit is preferably composed of at least one of the seating sensor and the buckle switch.

According to this configuration, the seating detection unit is configured using existing components of the seat device, such as a seating sensor or a buckle switch. Therefore, the seating detection unit can be easily realized.

In the control system for a vehicle seat device, it is preferable that the seating detection portion is constituted by both the seating sensor and the buckle switch.
Even when an occupant is seated in the seat, the seating sensor may detect that the occupant is not seated in the seat due to the occupant's posture, etc. In addition, even when an occupant is seated in the seat, the tongue of the seat belt may not be connected to the buckle. In this case, the occupant may be unable to operate the operating terminal even though he or she is seated in the seat.

In this regard, with the above configuration, the seating detection unit is composed of both a seating sensor and a buckle switch, so the occurrence of the above-mentioned inconveniences can be suppressed.

The present invention makes it possible to prevent the seat from being operated when the state of the vehicle interior is unknown.

The seat ECU 45 and the door ECU 46 are electrically connected to each other and configured to be able to communicate with each other.
The seat ECU 45 corresponds to a control unit according to the present invention.

<Operation terminal 70>
As shown in FIG. 3 , the operation terminal 70 is provided so as to be capable of wireless communication with the seat ECU 45 , and outputs operation signals to the seat ECU 45 for driving the slide motor 31 , the rotation motor 32 , and the reclining motor 33 .

As shown in FIG. 2, the operation terminal 70 has a substantially rectangular plate shape.
A touch panel 71 that can be operated by touching it with a finger is provided on a main surface of the operation terminal 70. The touch panel 71 is configured to be capable of displaying images of a slide operation unit 72 that operates the drive of the slide motor 31, a rotation operation unit 73 that operates the drive of the rotation motor 32, and a reclining operation unit 74 that operates the drive of the reclining motor 33.

The operation terminal 70 includes a terminal control unit 77 that controls the display of the touch panel 71, a detection unit 78 that detects touch operations on the touch panel 71, and a communication unit 79 that outputs a detection signal from the detection unit 78, i.e., an operation signal, to the seat ECU 45.

As shown in FIG. 5, the operation terminal 70 is equipped with a battery 75 .
A power receiving unit 76 is provided on the surface of the operation terminal 70 opposite to the touch panel 71, for receiving power from a charging device 50 that charges a battery 75 by wireless power supply.

<Charging device 50>
As shown in FIG. 1 , the armrest 23 is provided with a charging device 50 for charging the operation terminal 70 .

As shown in Figures 4 and 5, the upper surface 23a of the armrest 23 is provided with a recess 51 capable of accommodating an operating terminal 70. The opening 52 of the recess 51 is generally rectangular in plan view and extends in the front-rear direction L and the vehicle width direction W.

The opening 52 is provided with a widened portion 53 whose width in the vehicle width direction W is partially increased. The widened portion 53 is provided in the center of the opening 52 in the front-rear direction L.
A pair of claws 54 are provided on the front and rear edges of the opening 52 so as to protrude rearward and forward, respectively.

A power transmitting unit 44 that wirelessly transmits power to a power receiving unit 76 of an operation terminal 70 accommodated in the recess 51 is provided on the bottom surface of the recess 51 .
When the operation terminal 70 is accommodated in the recess 51 , the pair of claw portions 54 engage with the upper edge of the operation terminal 70 , thereby preventing the operation terminal 70 from slipping out of the recess 51 .

On the other hand, when the operating terminal 70 is housed in the recess 51, the occupant can insert their fingers into the widening portion 53 to grasp and pull up the operating terminal 70, thereby removing the operating terminal 70 from the charging device 50.

The recess 51 corresponds to a predetermined position according to the present invention.
Here, the operation terminal 70 includes an estimation unit that estimates whether the operation terminal 70 is located outside the vehicle. When the estimation unit estimates that the operation terminal 70 is located outside the vehicle, the operation terminal 70 prohibits the operation terminal 70 from operating the seat 20.

Specifically, the operation terminal 70 prohibits the operation terminal 70 from operating the seat 20 when the operation terminal detection unit detects that the operation terminal 70 is not in a predetermined position in the vehicle cabin, the seating detection unit detects that no occupant is seated in the seat 20, and the door detection unit detects that the sliding door 17 is open.

In this embodiment, the estimation unit is configured by the terminal control unit 77. The power transmission unit 44 of the charging device 50 configures the operation terminal detection unit. The seating sensor 42 and the buckle switch 43 configure the seating detection unit. The courtesy switch 41 configures the door detection unit.

Next, the procedure of the control process of the vehicle seat device according to the present invention will be described with reference to the flowchart in FIG. 6. The control process shown in FIG. 6 is executed by the terminal control unit 77 of the operation terminal 70 when the touch panel 71 of the operation terminal 70 is touched.

As shown in FIG. 6, in this series of processes, the terminal control unit 77 first acquires output signals from the courtesy switch 41, the power transmission unit 44 of the charging device 50, the seating sensor 42, and the buckle switch 43 via the seat ECU 45 (step S1).

Next, the terminal control unit 77 determines whether or not the operation terminal 70 is being charged by the charging device 50 based on the output signal from the power transmission unit 44 (step S2).
If the operation terminal 70 is being charged (step S2; NO), the terminal control unit 77 permits the touch operation, i.e., permits the operation of the second seat 12 by the operation terminal 70 (step S7). Then, the terminal control unit 77 ends the series of processes.

On the other hand, if the operation terminal 70 is not being charged (step S2; YES), the terminal control unit 77 next determines whether the operation terminal 70 is not present in the specified position within the vehicle cabin and determines whether an on signal is being output from the seat sensor 42 (step S3).

Here, if an ON signal is output from the seating sensor 42 (step S3; NO), the touch operation is permitted, that is, the operation terminal 70 is permitted to perform an operation of the second seat 12 (step S7). Then, the terminal control unit 77 ends the series of processes.

On the other hand, if an ON signal is not output from the seating sensor 42 (step S3; YES), the terminal control unit 77 then determines whether an ON signal is output from the buckle switch 43 (step S4).

Here, if an ON signal is being output from the buckle switch 43 (step S4; NO), the touch operation is permitted, i.e., the operation of the second seat 12 is permitted to be performed by the operation terminal 70 (step S7). Then, the terminal control unit 77 ends the series of processes.

On the other hand, if an ON signal is not output from the buckle switch 43 (step S4; YES), it is determined that no passenger is seated in the second seat 12, and the terminal control unit 77 then determines whether the signal output from the courtesy switch 41 has changed (step S5).

If the signal output from the courtesy switch 41 has not changed (step S5; NO), it is determined that the sliding door 17 is not open or closed, and the touch operation is permitted, i.e., the operation of the second seat 12 by the operation terminal 70 is permitted (step S7). Then, the series of processes is terminated.

On the other hand, if the signal output from the courtesy switch 41 has changed (step S5; YES), the sliding door 17 is determined to be open, and the terminal control unit 77 then prohibits the touch operation, i.e., prohibits the operation terminal 70 from operating the second seat 12 (step S6). The terminal control unit 77 then ends the series of processes. Note that in step S5, the signal output from the courtesy switch 41 changes in both the state in which the sliding door 17 is open and the state in which the sliding door 17 is closed after being opened, and these states can be grasped based on these changes.

The operation of this embodiment will be described.
When the terminal control unit 77 estimates that the operation terminal 70 is outside the vehicle, the operation terminal 70 prohibits the operation terminal 70 from operating the second seat 12 .

The effects of this embodiment will be described.
(1) The control device 40 includes a terminal control unit 77 that estimates whether the operation terminal 70 is located outside the vehicle.

According to this configuration, the above-mentioned effect is achieved, and therefore it is possible to prevent the second seat 12 from being operated in a situation where the state inside the vehicle cabin is unknown.
(2) The control device 40 includes a power transmission unit 44 , a seating sensor 42 , a buckle switch 43 , and a courtesy switch 41 .

When the operation terminal 70 is not charged, no on signals are output from the seating sensor 42 and the buckle switch 43, and the signal output from the courtesy switch 41 has changed, the operation terminal 70 prohibits the operation terminal 70 from operating the seat 20 device.

When an occupant moves from the inside of the vehicle cabin to the outside of the vehicle while holding the operating terminal 70, all three conditions are met: the operating terminal 70 is not in the recess 51, the occupant is not seated in the seat 20, and the sliding door 17 is open.

In this regard, according to the above configuration, when the power transmission unit 44, the seating sensor 42, the buckle switch 43, and the courtesy switch 41 detect that all three of the above conditions are met, the operation terminal 70 is prohibited from operating the seat 20. Therefore, it is possible to estimate with high accuracy that the operation terminal 70 is outside the vehicle.

(3) The power transmission unit 44 detects that the operation terminal 70 is present in the vehicle cabin when the operation terminal 70 is being charged by the charging device 50 .
Since the operation terminal 70 can wirelessly communicate with the control device 40, for example, the power transmission unit 44 may be configured to detect whether the operation terminal 70 is present inside the vehicle cabin based on the radio wave intensity of the operation terminal 70 received by the control device 40. In this case, however, the following problem may occur. That is, even if the operation terminal 70 is present inside the vehicle cabin, the operation terminal 70 may be detected as being outside the vehicle because the radio wave intensity is lower than a threshold value, which is a so-called false detection. In this case, an inconvenience may occur in which the occupant cannot operate the operation terminal 70 even though the operation terminal 70 is present inside the vehicle cabin.

In this regard, according to the above configuration, the presence of the operation terminal 70 inside the vehicle is detected based on information that the operation terminal 70 is being charged by the charging device 50. Therefore, at least when the operation terminal 70 is being charged by the charging device 50, the operation terminal 70 is not erroneously detected as being outside the vehicle even though it is actually inside the vehicle. Therefore, the occurrence of the above-mentioned inconvenience can be avoided.

(4) The seat cushion 21 is provided with a seating sensor 42 that detects whether an occupant is seated on the seat 20. The seat 20 is also provided with a seat belt 26 and a buckle 27. The buckle 27 is provided with a buckle switch 43 that detects whether the tongue 26a is connected to the buckle 27.

According to this configuration, it is possible to easily detect whether or not an occupant is present in the vehicle compartment by using the existing components of the seat device, such as the seating sensor 42 and the buckle switch 43 .
(5) The seating sensor 42 and the buckle switch 43 constitute a seating detection unit. Therefore, both the seating sensor 42 and the buckle switch 43 detect whether an occupant is present in the vehicle compartment.

Even if an occupant is seated in the second seat 12, the seating sensor 42 may detect that the occupant is not seated in the second seat 12 due to the occupant's posture, etc. Also, even if an occupant is seated in the second seat 12, the tongue 26a of the seat belt 26 may not be connected to the buckle 27. In this case, an inconvenience may occur in which the occupant cannot operate the operation terminal 70 even though the occupant is seated in the second seat 12.

In this regard, according to the above-described configuration, since it is detected by both the seating sensor 42 and the buckle switch 43 whether or not an occupant is present in the vehicle compartment, the occurrence of the above-described inconvenience can be suppressed.
<Example of change>
This embodiment can be modified as follows: This embodiment and the following modifications can be combined with each other to the extent that there is no technical contradiction.

The seating detection unit may be configured with only one of the seating sensor 42 and the buckle switch 43.
The seating detection unit is not limited to being configured by at least one of the seating sensor 42 and the buckle switch 43. For example, an image of the interior of the vehicle may be captured by an in-vehicle camera, and the captured image may be processed to detect whether or not an occupant is seated in the second seat 12. Alternatively, an infrared sensor may be used to detect whether or not an occupant is seated in the second seat 12.

The operation terminal detection unit is not limited to the power transmission unit 44 of the charging device 50. For example, an image of a predetermined position in the vehicle cabin may be captured by an in-vehicle camera, and the captured image may be subjected to image processing to detect whether the operation terminal 70 is present at the predetermined position.

In the above embodiment, the terminal control unit 77 of the operation terminal 70 constitutes the estimation unit. However, the seat ECU 45 may constitute the estimation unit.
In the above embodiment, the operation terminal 70 itself is configured to prohibit the operation of the second seat 12 using the operation terminal 70, but the seat ECU 45 may be configured to prohibit the operation of the second seat 12 using the operation terminal 70.

The door that opens and closes the rear boarding/alighting door 16 may be a hinged door.
The control system for a vehicle seat device in this embodiment can also be applied to the front seat 11 or the third seat 13. In this case, too, it is possible to prevent the front seat 11 or the third seat 13 from being reclined or otherwise operated when the state inside the vehicle cabin is unknown.

- The seat layout of the vehicle 10 is not limited to the three-row seating illustrated in the above embodiment, but may be two-row or four-row seating.
