  Next, the flow of processing of the window full-closed remote operation in the vehicle remote control system according to this embodiment in which each device has such a configuration will be described with reference to FIGS. FIG. 5 is a sequence diagram illustrating a flow of processing of the window full-closed remote operation, and FIG. 6 is a diagram illustrating an auto-close operation by the power window device 102 according to the present embodiment.

  First, a vehicle user accesses a Web page for a remote operation request provided by the Internet server function unit 303 of the center 103 from the communication terminal 104, and requests a window fully-closed remote operation for the vehicle 101 after user authentication ( S501).

  When the remote operation is requested in this manner, the center 103 transmits an operation command to the vehicle 101 (the power window device 102 thereof) using the transmission / reception unit 301 (S502).

  Next, on the vehicle 101 side, when the power window device 102 receives the window full closing operation command, the control unit 202 instructs the window glass driving unit 204 and the alarm sound output unit 205 to transmit the window glass through a predetermined operation pattern. Is moved to the fully closed position (S503).

  Here, the window fully closing operation (S503) of the power window device 102 according to the present embodiment will be described with reference to FIG.

First, when a window fully closing operation command is received at time t ₀ , the control unit 202 instructs the alarm sound output unit 205 to output a predetermined alarm sound. At this time, the window glass is not moved yet, but remains stopped.

The alarm sound is a predetermined period (in this case, until the time t _1), is output. Moreover, this alarm sound was continuously sounded during the alarm sound output period (time t _{0 to} t ₁ ) rather than a sound pattern such as “pi, pi, pi, pi ...”. A pattern such as "Pee-" is preferred.

After outputting the alarm sound for a predetermined period in this way, the control unit 202 then stops outputting the alarm sound at time t ₁ and instructs the window glass driving unit 204 to move the window glass from the current position. Move in the opening direction (downward) at a predetermined moving speed.

Here, it is assumed that continues to move the window glass in the opening direction until the time t _2. The driving period (time t _{1 to} t ₂ ) in the opening direction of the window glass may be a predetermined period, or may be defined as when the window glass has moved a predetermined distance in the opening direction.

After moving this way once the window glass in the opening direction, then the control unit 202 at time t _2, (in this case up to the time t ₃₎ the window glass predetermined period to the window glass drive unit 204 temporarily stopping.

After thus cause the window glass is stopped at a predetermined period one, then control unit 202 At time t _3, in the closing direction the window glass instructs the window glass driving unit 204 to the fully closed position at a predetermined moving speed move.

As described above, the power window device 102 according to the present embodiment, when fully closing the window by remote operation, before raising the window glass in the closing direction (time t _3- ), 1) alarm sound output (and window A glass stop period (time t _{0 to} t ₁ ), 2) a window glass falling period (time t _{1 to} t ₂ ), and 3) a window glass temporary stop period (time t _{2 to} t ₃ ). .

  That is, in the present embodiment, before the window auto-close operation, the vicinity of the window is divided into two stages (A) output of an alarm sound and B) a window opening operation that does not cause the possibility of crossing with surrounding objects. Is alerted to the movement of the window glass. As a result, a person near the window recognizes that the window full closing operation is performed, and responds so that a part of the body such as the hand does not cross the window glass (for example, retracting the hand, moving away from the window, etc.) )It is expected.

  In this embodiment, an alarm sound is first output, and the window glass starts moving after the alarm sound stops. This is thought to be in harmony with human sensitivity as a reminder before an object begins to move. A similar method is also employed in, for example, train platforms. In general, when a train platform is closed before departure, a sound such as an announcement or a melody is played and the door closing operation is started after the sound stops.

Further, in this embodiment, after the alarm sound output and the window opening operation, a temporary stop period (time t _{2 to} t ₃ ) in which the window glass does not move before the closing operation is started is provided. A person who is trying to retract his / her hand so as not to cross the window glass during the window opening operation is not surprised that the moving direction of the window glass changes rapidly from the opening direction to the closing direction. This is particularly useful for securing a time for retracting the hand when the window glass position is close to the fully closed position when the window fully closing operation command is received (time t ₀ ) and the gap is relatively narrow. Is.

  Returning to FIG. When the window fully closing operation is completed in this way, the control unit 202 transmits an operation completion notification to the center 103 through the communication unit 201 (S504).

  Next, on the center 103 side, when the transmission / reception unit 301 receives an operation completion notification from the vehicle 101, the control unit 302 instructs the Internet server function unit 303 to execute the power window remote operation requested by the vehicle user. A completion notification mail for transmitting the completion is generated and transmitted to the user communication terminal 104 (S505).

  Thus, according to the present embodiment, when performing the window full-close operation by remote operation, in view of the remote operator requesting the remote operation in a state where the vehicle state cannot be sufficiently confirmed, the window glass Before moving the window, it is possible to alert the person near the window that the window automatically operates effectively, so the power window operation by remote control can cause the window glass and a part of the person's body near the window to Crossing can be avoided appropriately.

  In the above embodiment, parameters such as alarm sound output time / type / frequency, window opening operation amount / time / speed, pause time, window closing operation speed, etc. can be arbitrarily set by the vehicle user. Is preferable for user convenience.

  In addition, these parameters may be appropriately modified according to the window glass position (height) at the time of a remote operation request. In particular, the window opening operation amount or time is preferably changed according to the initial position of the window glass (large / long when the initial position is high and small / short when the initial position is low).

  Further, the window closing operation speed (window glass rising speed) may be reduced when the window glass position reaches a predetermined distance to the fully closed position.

  Furthermore, in the above-described embodiment, the window fully closing operation pattern shown in FIG. 6 can be used when the window is fully closed by an operation other than the remote operation. Examples of cases other than remote control include: a) auto-close by manual switch operation from the driver's seat, b) auto-close performed by interlocking with the driver's seat door lock by mechanical key, c) auto-close by wireless key operation, d ) Auto close that works in conjunction with the smart entry system and that works in conjunction with the door lock.

  As will be apparent to those skilled in the art, when the window full-close operation pattern shown in FIG. 6 is applied to the above-mentioned a) to d), the pattern may be corrected in consideration of individual features and characteristics.

  For example, in the case of a), the warning sound output period may be omitted from the idea that the window can be closed after paying sufficient attention because the driver is in the vehicle.

  In the case of b), the temporary stop period may be made relatively short in view of the fact that the operator can stand close to the vehicle and the window can be closed with careful attention.

  The present invention is not limited to vehicles, and can be used for any power window device that can be remotely operated. When used in a vehicle as in the above-described embodiment, the appearance, weight, size, running performance, etc. of the vehicle to be mounted are not particularly limited.
