Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The outline of the system configuration of the window opening and closing apparatus according to this embodiment will be described mainly with reference to FIG. 1. The input circuit 1 a of the electronic control apparatus 1 that is a microcomputer for controlling the existing power window apparatus is provided for each of the windows 11 and 13. Touch sensor 2 as a living body sensing means provided in the vehicle, a central opening / closing switch provided on the armrest 10a of the driver's side front door, and an individual opening / closing provided on the armrest 12a for doors other than the front door. An output signal from the switch 4 and the open / closed state detection sensor 5 provided for each door is inputted, and the inputted signals are subjected to various controls by a CPU (Central Processing Unit) 1b, and based on the processing results. The electric motor 6 for raising and lowering the windows 11 and 13 built in each door by the drive command signal from the drive circuit 1c, the open / close state display section 7 (indicator) , Control object, such as a notification means serving buzzer 8 is remotely controlled.
In FIG. 1, only one touch sensor 2, individual opening / closing switch 4 and electric motor 6 are shown, but they are actually arranged at each door of the vehicle.
Hereinafter, these main components will be sequentially described.

  The touch sensor 2 is provided in each window provided on the doors of the vehicle such as the window 11 of the front door 10 and the window 13 of the rear door 12 on the side of the passenger seat of the right-hand drive vehicle. Specifically, at the position indicated by the oblique lines in FIG. 2, a band-shaped touch sensor 2 having a predetermined width along the upper end surface of each window 11, 13 and the vehicle interior side upper edge along the upper end surface is appropriately coated with a transparent adhesive. , Pasted so as not to disturb the view. For example, as shown in FIG. 3, the touch sensor 2 includes a pair of electrodes 2a and 2b having a comb-like pattern arranged opposite to each other. Each electrode 2a and 2b is formed of indium oxide, tin oxide, or the like. And having a structure coated with a transparent insulating resin material. When a living body such as a finger approaches or touches the touch sensor 2, the capacitance between the electrodes 2a and 2b decreases, and by detecting the change, it is sensed that the living body has approached or contacted the window. It is like that.

The centralized opening / closing switch 3 is used to drive the electric motor 6 built in each door and to open / close (lift) the windows 11 and 13. The individual opening / closing switch 4 controls opening / closing of the windows 11 and 13 for each window of each door. The central open / close switch 3 and the individual open / close switch 4 form a known power window switch, and these switch signals are sent to the input circuit 1a.
The open / closed state detection sensor 5 is attached to each of the doors 10, 11 and the like, detects the open / closed state of each window, and the detection result is output to the open / closed state display unit 7 to be described later via the drive circuit 1c. It has become.

  Next, the electronic control device 1 will be described. That is, as shown in FIG. 1, the electronic control device 1 has an input circuit 1a connected to the input side of the CPU 1b and a drive circuit 1c connected to the output side. The ROM (not shown) includes a prohibition control program for forcibly prohibiting the closing operation of each window, a closing operation prohibition canceling control program for canceling the closing operation prohibition, a display control program for performing display on the opening / closing state display unit 7, In addition, various programs such as a measurement control program for measuring the operation time of the buzzer 8 and the standby time for canceling the prohibition of the closing operation are stored, and the CPU 1b executes these control programs so that the electronic control device 1 has the closing operation prohibition control means. 1d, a closing operation prohibition release means 1e, an open / close state display control means 1f, and a timer means 1g are formed.

As a result of the calculation processing by the closing operation prohibition control means 1d, the driving of the electric motor 6 is controlled by a drive command signal that has passed through the driving circuit 1c. For example, a body such as a finger approaches or comes into contact with a window in the open operation state. In such a case, even if an operation of closing the window in the open state is performed, the drive to the closed state is forcibly prohibited.
Further, the closing operation prohibition release means 1e releases the closing operation prohibition state and closes the window when a finger leaves the window in the open state where the closing operation is prohibited.
The calculation processing result by the open / close state display control means 1f is output to the open / close state display unit 7 via the drive circuit 1c, and the open / closed state of each window is turned on and off and displayed as a picture.
The timer means 1g is closed when the touch sensor 2 senses that a hand, a finger or the like has touched the window, and when the buzzer 8 that blows from the touch sensor 2 or when the touch sensor 2 stops touching the finger. This is for measuring the waiting time until the operation prohibition is canceled.

  Next, the opening / closing state display unit 7 will be described. As shown in FIG. 4, the open / close state display unit 7 is installed in a place where a driver or the like such as an instrument panel (not shown) or the armrest 10a can easily see, and displays the vehicle body in a plan view. It is formed of segments 7a to 7d (display elements) for lighting the door window in color. Specifically, when the windows 11 and 13 are closed, the corresponding window segment is turned off, and when the windows 11 and 13 are opened, the corresponding segment is turned on in yellow, for example. Yes.

  Control of the window opening and closing apparatus according to the present embodiment will be described with reference to the flowcharts shown in FIGS. That is, when the CPU 1b starts control, the open / closed state display control means 1f determines whether the windows 11 and 13 are opened or closed by a switch signal from the central opening / closing switch 3 or the individual opening / closing switch 4 in step S1. . When the windows 11 and 13 are not opened (the windows are closed), the segments 7a to 7d of the open / close state display unit 7 corresponding to the windows remain unlit (step S2) until the windows are opened. Step S1 and step S2 are repeated.

  If it is determined in step S1 that the window is opened by the detection signal from the opening / closing state detection sensor 5, the segments 7a to 7d of the opening / closing state display unit 7 corresponding to the windows 11 and 13 opened in step S2 are turned on. Thus, the driver emits yellow light, and the driver knows that the windows 11 and 13 corresponding to the segments to be lit are in the open state.

  In step S4, it is determined whether or not the windows 11 and 13 in the open state have been closed by the central opening / closing switch 3, and if the closing operation is not performed, steps S3 and S4 are repeated. If it is determined in step S4 that the closing operation has been performed, the process proceeds to step S5 to receive a closing operation switch signal of the central opening / closing switch 3, and a human finger, hand, face is applied to the touch sensor 2 of the open window. Or the like is determined by the closing operation prohibition control means 1d. When the closing operation prohibition control means 1d determines that the body or a living body such as a pet is approaching or touching (affirms), the timer means 1g starts measuring the operating time of the buzzer 8 (step S6). (Step S7), the driver is informed that the closing operation is not executed, and the switch signal for closing the central opening / closing switch 3 is canceled by the drive command signal from the drive circuit 1c. Thus, the electric motor 6 is not driven, whereby the window 13 is kept open (step S9), and is stopped after the buzzer 8 sounds for a predetermined time by the timer means 1g (step S10). Thereby, the situation where fingers, such as a child, are pinched by the window 13 can be prevented beforehand.

  In step S11, it is determined by the closing operation prohibition releasing means 1e whether or not the body has subsequently left the window for which the closing operation is prohibited by the touch sensor 2. As long as it is determined to be in a contact or close state, the step S11 is repeated and the closing operation is continuously prohibited, and the window is kept open. On the other hand, if it is determined that the timer is separated, the timer is activated by the timer means 1g in step S12, and measurement of a predetermined waiting time suitable for operating so as to close the window is started. The timer means 1g measures whether a predetermined waiting time has elapsed after releasing the finger, and based on the measurement result, it is determined whether or not the closed operation prohibited state is canceled by the closed operation prohibition releasing means 1e (step S13). ). If it is determined that the closed operation prohibition state may be canceled after a predetermined waiting time has elapsed, the electric motor 6 is driven in step S14, and the window that has been left open until then is opened. The closing operation is performed (step S15).

  Thus, when the window is closed, based on the signal detected by the open / close state detection sensor 5, a signal is output from the open / close state display control means 1f to the corresponding segments 7a to 7d of the open / close state display unit 7, and the light is turned off. Thus, the driver can confirm that the window is completely closed (step S16).

  On the other hand, if the result of sensing by the touch sensor 2 is determined to be NO in step S5, the body is not in contact with the window and the command signal for permitting driving of the electric motor 6 from the closing operation prohibition control means 1d. Is output to the drive circuit 1c (step S17), the window is raised and closed (step S18), the corresponding segments 7a to 7d of the open / close state display unit 7 are turned off, and the window is closed. (Step S19), the opening / closing control of the window ends.

  According to this embodiment, unlike the conventional technique, when the body is sandwiched between the windows to be closed, the body is sandwiched, unlike the case where the electric motor is reversed and the windows are lowered and opened. Before touching, the touch sensor 2 detects whether the body is touching or approaching the window in advance, and when the touch is detected, the closing operation prohibiting control means 1d closes the window. Cancel to prevent children from getting caught in the window. In addition, when a child or the like lifts a finger or the like from the window, the window is automatically closed by the closing operation prohibition solving means 1e after a predetermined waiting time has elapsed, so that the driver can open the window in the open state. When you close the window, you can close the window by simply operating the central opening / closing switch 4 without worrying about whether children are approaching or touching the window. When the vehicle is running, it is possible to avoid the operation after confirming the state of the child in the rear seat and confirming the safety, thereby ensuring safe driving. In addition, since the window open / close state is turned on and off by the segment display on the open / close state display section 7, it is convenient to grasp the open / close state of the window at a glance, and when the closing operation is prohibited. Since the buzzer 8 is sounded, it can be judged by hearing that someone is putting a hand or a finger on the open window, so that there is an advantage that driving operation can be concentrated.

As described above, the present invention has been described in detail by using the embodiments. However, the specific configuration is not limited to these embodiments, and the present invention includes any design changes that do not depart from the gist of the present invention. It is.
For example, in the above-described embodiment, the case where a window opened halfway is closed has been described. However, the present invention can be applied to a case where a window opened at an intermediate opening is further opened. That is, a plurality of windows that are opened and closed by each electric motor mounted on the vehicle, a central opening / closing switch disposed in the vicinity of the driver's seat for centrally opening / closing the windows, and a window other than the vicinity of the driver's seat among the windows. Individual open / close switch for individually opening / closing, opening / closing state detecting means for detecting the open / closed state of each window, living body sensing means for detecting the approach / contact of a living body such as a hand or a finger provided in each window, and the centralized opening / closing A window in an intermediate opening state is operated to an open state by a switch, the open / closed state detecting means detects the open state of the window, and the living body sensing means detects the open state and the living body approaches / contacts the window. When an open operation prohibition control means for prohibiting the drive of the electric motor to the open state is provided, children touching the window are unexpectedly opened out of the vehicle by opening the window unexpectedly. Situation It can be reliably prevented.

Moreover, although the said embodiment demonstrated the case where it applied to opening and closing of the side door of a vehicle, it cannot be overemphasized that it can apply also to the vehicle carrying a sunroof apparatus. In this case, as indicated by the two-dot chain line in FIG. 4, the sunroof is displayed by providing segments 7e and 7f for displaying the sunroof in correspondence with the position where the sun rule of the open / close state display unit 7 is arranged. The open / closed state of can be displayed.
In the above, as shown in the flowchart of FIG. 6, when the touch sensor 2 senses that the finger is not touching the window by the closing operation prohibition releasing means 1e, it waits for a certain period of time. Although the window is formed so as to be closed automatically later, the processing in steps S11 to S16 may be omitted.
Further, in the above, the window closing operation is controlled by the closing operation prohibition releasing means 1e after waiting for a certain period of time. However, without waiting for a certain period of time, the window is immediately closed when a finger or the like leaves the window. It can also be made.
In the above description, when the window closing operation is prohibited, the buzzer 8 is sounded. Instead, the segment of the open / close state display unit 7 can be blinked.
The open / close state display unit 7 is formed by using a light emitting diode or the like. Instead, the monitor screen of a personal computer connected to the in-vehicle network system, the in-vehicle network system, or independent navigation is used.
