As shown in FIG. 4, the window opening / closing device 10 includes a power window regulator (hereinafter referred to as a PW regulator) 14 that raises and lowers the side door window 12, and electrostatic discharge caused by an operator touching the side door window 12 with a finger. Capacitance sensors 16A to 16E that detect a change in capacitance, and a window movement instruction position that the operator touches with a finger based on the change in capacitance of the capacitance sensors 16A to 16E, and the window to that position The control part 18 which controls the PW regulator 14 is provided.

  As shown in FIGS. 1 to 3, the capacitance sensors 16 </ b> A to 16 </ b> E are U-shaped wirings on the inner surface 20 </ b> A of the window glass 20 constituting the side door window 12, and are respectively connected to electrodes (not shown). And are formed at predetermined intervals at different positions in the height direction (actually, a larger number of wirings are arranged at a high density, but the number is limited to five for explanation).

  The PW regulator 14 includes a window position detection unit 22 that detects the current position of the window glass 20 and a motor 24 that moves the window glass 20 up and down.

  The control unit 18 includes a touch signal detection unit 26 that detects which position the operator has touched from changes in the output signals of the capacitance sensors 16 </ b> A to 16 </ b> E and detects a movement instruction position, and a touch signal detection unit 26. Based on the detected movement instruction position and the current position of the window detected by the window position detection unit 22, the movement distance of the window glass 20 is calculated, and the motor control unit 28 outputs a drive signal to the motor 24. .

  (Operation and effect of this embodiment)

  Next, the operation and effect of this embodiment will be described.

  The case where the fully-closed window glass 20 is opened to a predetermined position will be described with reference to the flowchart of FIG. The touch signal detection unit 26 of the control unit 18 detects the movement instruction by a finger or the like by comparing the outputs of the capacitance sensors 16A to 16E with a reference value (step 100). If there is no operation, the output of any of the capacitance sensors 16A to 16E does not change, and the touch signal detection unit 26 repeats this operation with no touch signal detected (N in step 100). On the other hand, when the operator touches the fingertip with the movement instruction position of the inner surface 20A of the window glass 20 (see FIG. 5A), the capacitance of the capacitance sensor 16C at that position changes. As a result, when the output value exceeds the reference value due to the change in the capacitance of the capacitance sensor 16C, the touch signal detection unit 26 determines that the operator has given an instruction to move, and detects the position (for example, from the top of the window The distance to the capacitance sensor 16C) is detected as a movement instruction position, and the movement instruction position is output to the motor control unit 28 (step 102). The motor control unit 28 detects the current position of the window glass 20 based on the output from the window position detection unit 22 (step 104), and based on the current position and the movement instruction position detected by the touch signal detection unit 26. Then, the amount of movement of the window glass 20 is calculated, and a drive signal corresponding to the amount of movement is output to the motor 24 (step 106). As a result, the motor 24 of the PW regulator 14 is driven, and the window glass 20 is lowered to the movement instruction position touched by the finger (see FIG. 5B).

  As described above, the window opening / closing device 10 according to the present embodiment directly touches the position (movement instruction position) where the window glass 20 is to be opened with a finger or the like, and the movement instruction position is detected by the capacitance sensors 16A to 16E at the position. Is detected, and the window glass 20 can be accurately opened to the position by driving the motor 24. That is, if the window glass movement instruction position is touched with a finger or the like, the window glass 20 accurately moves to that position. Therefore, the conventional power window apparatus that finely adjusts the position of the window glass while repeatedly pressing the switch. Excellent operability compared to

  Here, although not specified in particular, it can be configured that the movement instruction is determined only when the detection time in the capacitance sensors 16A to 16E exceeds a certain time. By comprising in this way, it can avoid misdetecting that it is a movement instruction | indication to what contacted the window glass 20 accidentally, and can open the window glass 20. FIG.

  Here, the capacitance sensors 16A to 16E are formed by wiring formed on the inner surface 20A of the window glass 20. However, as shown in FIG. 7, the transparent electrode 29 such as a titanium oxide film has the same pattern as the wiring. It can also form by sticking on the inner surface 20A of the window glass 20.

  Further, as shown in FIGS. 8 and 9, for the side door window 12 composed of two window glasses (laminated glass) 30A and 30B, a fine electric wire pattern 32 is printed on a film 34, and the window It can be set as the same structure by inserting between glass 30A, 30B as an intermediate film. In this case, the capacitance sensor configured as an electric wire pattern changes the capacitance when the finger touches the window glass 30A without touching the capacitance sensor directly. The window glasses 30A and 30B can be accurately moved to the position. Thus, since the finger etc. do not touch directly, the electric wire pattern 32 does not wear and is excellent in durability.

  In addition, although this embodiment demonstrated the side door window 12, it is not limited to this. For example, the same capacitance sensors 16A to 16E can be provided on the sliding roof 40 as shown in FIG. 10, and the movement instruction position can be touched to open the position (see FIGS. 11A and 11B). ).

  Furthermore, although only the case where the window glass 20 was opened was demonstrated in this embodiment, it is also possible to make it operate | move in the obstruction | occlusion direction by tracing the surface of the window glass 20 toward the upper side. Alternatively, a configuration in which the window glass 20 is fully closed by double-clicking (contacting it twice) is also possible.

Specifically, if the ignition key is inserted, it is determined that the vehicle is on board (not parked) (N in Step 200), and the window opening device 10 is controlled (Step 100 to Step 106). At this time, if the touch signal is not detected in Step 100 (N in Step 100), the process returns to Step 200.

  On the other hand, if the ignition key is not inserted and the door key is locked, it is determined that the vehicle is parked (Y in Step 200), and the capacitance sensors 16A to 16A detected by the touch signal detection unit 26 are used. The output of 16E is output to the window abnormality detection unit 52. When the window glass 20 of the side door window 12 is broken or when a suspicious person approaches the window glass 20, the window abnormality detection unit 52 changes the capacitance of any one of the capacitance sensors 16A to 16E. If it exceeds the reference value, it is determined that an abnormality has occurred in the side door window 12, and a drive signal is output to the security horn 54 (step 202). Accordingly, the suspicious person's action can be abandoned by driving the security horn 54.

  In addition, when it drives as the window abnormality detection system 50 during parking in this way, it does not operate | move as the window opening apparatus 10. FIG. That is, the side door window is not opened when a suspicious person or the like approaches and contacts the window glass 20.
