In recent years, in such vehicle seat control devices, it has been considered to provide an operation terminal detachable from the seat as an operation unit. The operation terminal is provided so as to be able to wirelessly communicate with the seat ECU, and outputs an operation signal for driving the slide drive unit and the like to the seat ECU. In this case, the occupant can operate the seat using the operation terminal even when the armrest is out of reach.

However, in this case, the following problems may occur. That is, when an occupant takes an operation terminal out of the vehicle and operates a seat of the vehicle, there is a possibility that the seat may be operated without knowing the state of the vehicle interior. As a result, there is a possibility that the seat may interfere with baggage or the like placed on the floor of the vehicle.

A control system for a vehicle seat device for solving the above-mentioned problems includes a seat device having a seat configured to be movable in a vehicle interior and a motor for driving the seat, and a control unit for controlling the driving of the motor. and an operation terminal that is provided so as to be able to communicate wirelessly with the control unit and that outputs an operation signal for driving the motor to the control unit. The control device or the control unit includes an estimation unit that estimates whether or not the operation terminal exists outside the vehicle. When it is presumed that it exists, execution of the operation of the seat device by the operation terminal is prohibited.

According to this configuration, when the estimation unit estimates that the operation terminal is outside the vehicle, 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 prevent the seat from being operated under a situation in which the state of the vehicle interior is unknown.

In the vehicle seat device control system, the control device includes an operation terminal detection unit that detects whether or not the operation terminal is present at a predetermined position in the vehicle interior, and whether or not an occupant is seated on the seat. and a door detection unit for detecting an open/closed state of a door that opens and closes an entrance for an occupant seated on the seat to get on and off. The operation terminal detection unit detects that the operation terminal is not at the predetermined position, the seating detection unit detects that no occupant is seated on the seat, and the door detection unit detects that the passenger is not seated on the seat. It is preferable that execution of the operation of the seat device by the operation terminal is prohibited when the opening of the door is detected by the operation terminal.

When the occupant moves from the vehicle interior to the exterior of the vehicle with the operation terminal in hand, there are three conditions: the operation terminal is not at a predetermined position in the vehicle interior, the occupant is not seated in the seat, and the door is open. all come true.

According to the above configuration, when the operation terminal detection unit, the seating detection unit, and the door detection unit detect that all of the above three conditions are satisfied, the operation terminal executes the seat operation through the operation terminal or the control unit. is prohibited. Therefore, it can be estimated with high accuracy that the operation terminal exists outside the vehicle.

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

Since the operation terminal can wirelessly communicate with the control unit, for example, the operation terminal detection unit detects whether or not the operation terminal exists in the vehicle interior based on the radio wave intensity of the operation terminal received by the control unit. can also be However, in this case, the following problems may occur. In other words, even though the operating terminal is inside the vehicle, the radio wave intensity becomes lower than the threshold value, so that it is detected that the operating terminal is outside the vehicle. . In this case, the passenger cannot operate the operation terminal even though the operation terminal is inside the vehicle.

In this respect, according to the above configuration, it is detected that the operating terminal is present at a predetermined position in the vehicle compartment based on the information that the operating terminal is being charged by the charging device. Therefore, at least when the operation terminal is being charged by the charging device, it is not erroneously detected that the operation terminal is outside the vehicle even though the operation terminal is inside the vehicle. Therefore, it is possible to avoid the occurrence of the inconvenience described above.

In the vehicle seat device control system described above, the seat has a seat cushion and a pressure-sensitive seating sensor provided on the seat cushion, and the seat restrains an occupant sitting on the seat. The buckle is provided with a detachable seat belt tongue, and the buckle is provided with a buckle switch for detecting whether or not the tongue is connected to the buckle. It is preferable that at least one of the seating sensor and the buckle switch is used.

According to this configuration, the seating detection section is configured by the existing configuration of the seat device such as the seating sensor or the buckle switch. Therefore, the seating detection unit can be easily implemented.

In the vehicle seat device control system described above, it is preferable that the seating detection unit includes both the seating sensor and the buckle switch.
Even if an occupant is seated on the seat, the seat sensor may detect that the occupant is not seated on the seat due to the posture of the occupant. Moreover, even when an occupant is seated on the seat, the tongue of the seat belt may not be connected to the buckle. In this case, the occupant cannot operate the operation terminal even though the occupant is seated on the seat.

In this respect, according to the above configuration, since the seating detection section is composed of both the seating sensor and the buckle switch, the occurrence of the above-described inconvenience can be suppressed.

According to the present invention, it is possible to prevent the seat from being operated under a situation in which the state of the vehicle interior is unknown.
