  In the embodiment of the present invention, an electric motor 3 as a drive source, a motor control unit 32 for controlling the electric motor 3, and a vertical position of the window glass 100 are detected in a power window opening / closing device including the window regulator 1. And a sensor 31 for input to the motor control device 32.

  The motor control unit 32 receives a detection signal of a sensor 31 that detects the vertical position of the window glass 100 by turning ON / OFF the power window switch 103a (or 103b to 103d, which will be described below as a representative). The electric motor 3 is controlled. Further, when the window glass 100 is fully closed by the closing signal of the power window switch 103a, the motor control unit 32 further continues the power window switch 103a in the closing direction multiple times (preferably twice) from the fully closed position of the window glass 100. When operated in a continuous manner, the corresponding window glass 100 is opened from the fully closed position to a predetermined opening degree and held in this state.

  In addition, the motor control unit 32 sets the opening setting value of the window glass 100 and the sensor 31 when the power window switch 103a is operated twice in the closing direction (may be a plurality of times, and the same applies hereinafter). The detection signal of the opening degree of the window glass 100 input from is configured to match. Therefore, the opening degree detection signal from the sensor 31 and the set value of the opening degree of the window glass 100 can be made to always coincide with the target value, and the opening degree of the window glass 100 can be matched with the target value. Can be accurately set to a desired opening at all times.

  Next, the operation of the automobile power window according to the present embodiment will be described. FIG. 2 is an operation flowchart of the automobile power window according to the embodiment of the present invention.

  The motor control unit 32 detects the operation of the power window switch 103a, and detects the operation in the closing direction and the operation in the opening direction (step S1). When the operation of the power window switch 103a detects an operation in the opening direction in step S1 (“opening direction” in step S1), the motor control unit 32 proceeds to step S2 and operates the operation amount of the window switch 103a in the normal mode. Accordingly, the electric motor 3 is controlled so as to move the window glass 100 in the opening direction. When the operation of the power window switch 103a detects an operation in the closing direction (“Closed direction” in Step S1), the motor control unit 32 proceeds to Step S3 and determines whether or not the position of the window glass 100 is the fully closed position. To detect.

  When the position of the window glass 100 is not the fully closed position (“N” in step S3), the motor control unit 32 proceeds to step S2 and closes the window glass 100 according to the operation amount of the power window switch 103a in the normal operation mode. The electric motor 3 is controlled to move in the direction. On the other hand, when the motor control unit 32 detects only one operation in the closing direction of the window glass 100 when the window glass 100 is fully closed (“Y” in step S3) (“Y” in step S4), Control is performed to prohibit the operation of the electric motor 3 (step S5). When the motor control unit 32 detects an operation in the closing direction of the window glass 100 twice continuously within a predetermined period when the window glass 100 is fully closed (“Y” in step S6), the motor control unit 32 opens the window in the special mode. The electric motor 3 is controlled to move the glass 100 from the fully closed position to a predetermined open position that is slightly opened (step S7).

  Next, another operation of the automobile power window according to the present embodiment will be described. FIG. 3 is another operation flowchart of the automobile power window according to the embodiment of the present invention. The operation example of FIG. 3 is an example in which control is performed so that the window glass 100 is moved to a predetermined open position even when an operation in the opening direction is detected at the fully open position of the window glass 100.

  The motor control unit 32 detects the operation of the power window switch 103a, and detects the operation in the closing direction and the operation in the opening direction (step S11). When the operation of the power window switch 103a detects an operation in the closing direction (“closing direction” in step S11), the motor control unit 32 proceeds to step S12 and detects whether the position of the window glass 100 is the fully closed position. To do. When the position of the window glass 100 is not the fully closed position (“N” in step S12), the motor control unit 32 proceeds to step S18 and moves the window glass 100 in the closing direction according to the operation amount of the window switch 103a in the normal mode. The electric motor 3 is controlled to move.

  The motor control unit 32, when the window glass 100 is fully closed (“Y” in step S12), detects an operation in the closing direction of the window glass 100 only once (“Y” in step S13). 3 is controlled to be prohibited (step S16). When the motor control unit 32 detects the operation in the closing direction of the window glass 100 twice in succession within a predetermined period (“Y” in step S14), the motor control unit 32 opens the window glass 100 slightly from the fully closed position. The electric motor 3 is controlled to move to the open position (step S15). The operation so far is the same as the operation example of FIG.

When the motor control unit 32 detects an operation in the opening direction of the power window switch 103a in step S11 (“opening direction” in step S11), the motor control unit 32 proceeds to step S17 and determines whether or not the position of the window glass 100 is the fully opened position. To detect. When the position of the window glass 100 is not the fully open position (“N” in step S17), the motor control unit 32 proceeds to step S18 and moves the window glass 100 in the opening direction according to the operation amount of the window switch 103a in the normal mode. The electric motor 3 is controlled so that When the motor control unit 32 detects the operation in the opening direction of the window glass 100 only once when the window glass 100 is fully opened (“Y” in step S17) (“Y” in step S19), the electric motor 3 Control is performed so as to prohibit the operation (step S16).
The motor control unit 32 fully opens the window glass 100 when the operation in the opening direction of the window glass 100 is detected twice continuously within a predetermined period (“Y” in step S20). The electric motor 3 is controlled to move to a predetermined open position slightly opened from the position (step S15).

  If configured as described above, it is possible to open the window glass to a desired opening degree by detecting a simple operation such as an operation in the closing direction, so that the power window device can open the window glass slightly with a simple configuration. Can be realized. Also, subtle artificial control is not necessary. Furthermore, since it is realized by an operation opposite to the operation in the opening direction, that is, the operation in the closing direction, an erroneous operation can be prevented. Furthermore, it is possible to slightly open the window glass from the fully opened position with a simple configuration.

[Second Embodiment]
Next, the second embodiment will be described. In the second embodiment, the window glass corresponding to the case where the first embodiment detects the operation in the closing direction of the driver window power window switch 103a (or 103b to 103d) twice in a predetermined period is fully closed. Although it was designed to be opened slightly from the position, the operation of the passenger seat power window switch 103b provided on the driver's seat side is detected, and the target windows are all the windows including both the left and right front seats or the rear seats. It is the same that the window glass is slightly opened from the fully closed position when the operation in the closing direction is detected twice continuously within a predetermined period. However, the premise that the window glass is in a fully closed state remains unchanged, and windows that are not fully closed are not controlled.

In the case of the present embodiment, the window glass is operated by a very special operation in which the passenger window power window switch 103b provided on the driver's seat side is continuously performed twice within a predetermined period with the window glass being fully closed. Since it can be opened a little, there is less concern about misoperation, and several windows can be opened a little at the same time.
Further, the driver window power window switch is often provided with an automatic function that can be automatically opened and closed by a one-touch operation. However, the above function is realized for the operation of the passenger window power window switch 103b. There is also an advantage that control complexity and control interference can be prevented.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various changes and modifications can be made based on the technical idea of the present invention. For example, in the above-described embodiment, the example in which the operation in the closing direction or the opening direction of the window switch is detected twice in succession has been described. It is also possible to target the window glass and to cover the entire window glass for three consecutive times. Moreover, although the said embodiment demonstrated the case of the window switch 103a as an example, this invention is not limited to this, It can also apply to the window switches 103b-103d. In the above-described embodiment, the description has been given by taking one opening position as an example with a predetermined opening position where the window glass is slightly opened. However, the present invention is not limited to this, and a plurality of window glass opening positions are provided. Depending on the number of operations, the target open position may be selected from a plurality of open positions.
In the above embodiment, the vertical position of the window glass is detected by a sensor. However, the sensor is not necessarily required, and the fully closed position of the window glass is detected by an overcurrent flowing through the motor. Alternatively, the motor driving time may be controlled to control the window glass to a predetermined open position slightly opened from the fully closed position.
