  As shown in FIG. 2, the motor unit 71 includes a motor 24 that drives a power window regulator (opening / closing mechanism) and a motor ECU 73 that controls the motor 24. Further, the motor unit 71 is also provided with a Hall IC 75 and a magnet for detecting the rotation speed and rotation direction of the armature of the motor 24.

  As shown in FIG. 1, the vehicle door 10 is provided with a switch 81 for operating a power window regulator. A sensor ECU 85 is provided between the switch board 83 of the switch 81 and the motor unit 71. That is, the sensor ECU 85 is provided on the input side of the motor ECU 73.

  As shown in FIG. 2, in this embodiment, the sensor ECU 85 has an 8-pin female connector 85a to which signals are input and an 8-pin male connector 85b to output signals.

  Further, the motor unit 71 is provided with an 8-pin input female connector 71a to which a signal is input.

  A signal line from the outer electrode 55 of the capacitance sensor 15 and an 8-core multi-core cable 87 are connected to the switch board 83 of the switch 81. An 8-pin male connector 89 is attached to the tip of the multicore cable 87.

  In this embodiment, the male connector 85b of the sensor ECU 85 can be connected to the female connector 71a of the motor unit 71, and the female connector 85a of the sensor ECU 85 is a female connector having the same shape as the female connector 71a of the motor unit 71. .

  As shown in FIG. 3, (1) a signal from the capacitance sensor 15 and (2) an up signal (UP SW: closing operation signal) from the switch board 83 to the sensor ECU 85 via an 8-core multi-core cable 87. (3) A down signal (DN SW: open operation signal) and (4) an auto signal (AUTO SW) are input.

  The multicore cable 87 is provided with (5) a power supply line (+ B) and (6) a ground line (GND). Furthermore, (7) in-vehicle LAN (LIN) line and (8) LED line (LED) which will be described later are also provided.

  Further, (2) up signal (UP SW: closing operation signal), (3) down signal (DN SW: opening operation signal), and (4) auto signal (AUTO SW) are input from the sensor ECU 85 to the motor ECU 73. The Further, (5) power supply line (+ B) and (6) ground line (GND) are provided between the sensor ECU 85 and the motor ECU 73. Furthermore, (7) in-vehicle LAN (LIN) line and (8) LED line (LED) which will be described later are also provided.

  The LED line turns on the LED provided in the switch 81 according to the state of the motor ECU 73. In a normal case, the LED is turned on. In the power-off mode or the power saving mode, the LED is turned off. If there is an abnormality, the LED is blinked.

  The sensor ECU 85 of this embodiment outputs the auto signal, the up signal, and the down signal to the motor ECU 73 as they are. Further, the power line, the ground line, the in-vehicle LAN line, and the LED line are also directly passed to the motor ECU 73.

  When the up signal and the auto signal are input, the motor ECU 73 according to the present embodiment enters an auto mode in which the motor 24 is continuously driven in the direction in which the window glass 14 is raised.

  When the up signal and the auto signal are input, the sensor ECU 85 performs the operation shown in FIG. FIG. 4 is a flowchart of the sensor ECU. In the figure, when the sensor ECU 85 receives the up signal and the auto signal, the sensor ECU 85 detects the capacitance of the capacitance sensor 15, and the detected capacitance (Q) becomes larger than the set threshold value (Q0). If it is determined that the foreign object has been caught, the down signal is turned on to lower the window glass 14 in order to avoid the foreign object from being caught (steps 1, 2, and 3).

  This down signal is given only for a set time (T1: time required for the window glass 14 to descend and release the pinch) (step 4).

  When the window glass 15 is lowered for the set time (T1), the down signal is turned OFF (step 5), and the series of operations is stopped.

  In addition, the detection of the capacitance of the capacitance sensor 15 in step 2 is performed only for a set time (T2: time required for the fully closed window glass 14 to rise to the fully closed state) (step 6). ). When the detection of the electrostatic capacity of the electrostatic capacity sensor 15 has passed the set time, it is determined that the window glass 15 is fully closed, and the operation ends.

  According to such a configuration, the following effects can be obtained.

 (1) A foreign object pinching detection device (capacitance sensor 15, sensor ECU 85) can be attached to the motor unit 71 of the power window regulator easily and at low cost by retrofitting.

  Further, since the sensor ECU 85 of the foreign object pinching detection device to be attached later detects the foreign object pinching by the change in capacitance of the capacitance sensor 15, the foreign object pinching detection is performed from the load state of the motor 24 performed by the motor ECU 73 of the motor unit 71. The response is quicker and foreign object pinching can be detected in a short time.

(2) When the sensor ECU 85 determines that a foreign object is caught while the auto signal is being input, the sensor ECU 85 stops the auto signal and outputs a down signal for a certain period of time, thereby allowing the motor 24 to operate at a load exceeding the rated value for a long time. Can prevent the coil of the motor 24 from burning out.
(3) Since the connector of the sensor ECU 85 is a male connector 85b that can be connected to the female connector 71a of the motor unit 71, the male connector 85b of the sensor ECU 85 can be directly connected to the female connector 71a of the motor unit 71. A cable for electrically connecting the sensor ECU 85 and the motor unit 71 is not necessary.

  In the above embodiment, the sensor ECU 85 detects foreign object pinching only when an auto signal is input. However, when the up signal is input, the sensor ECU 85 also detects foreign object pinching. Also good.

  Further, when the down signal is input from the switch 81 during the auto mode, the control for driving the motor 24 in the direction of lowering the window glass 14 is performed. However, the control for stopping the motor 24 may be performed.

Furthermore, although the electrostatic capacity sensor 15 is used as a sensor for detecting the foreign object, the present invention is not limited to this. For example, the sensor having the cross-sectional structure shown in FIG. 5 may be a sensor that detects foreign object pinching by bringing the outer electrode 55 and the inner electrode 57 into contact and conducting when the foreign object is pinched.
Second Embodiment
This embodiment is an example in which the present invention is applied to a power slide door.

As an example, a power slide door has a rail provided along the door opening and closing direction, and is movably engaged with the rail, and moves to one side of the rail to open the vehicle opening (fully open). The door is configured to move to the other side of the rail, thereby closing the vehicle opening (fully closed state) and a drive mechanism for driving the door. Furthermore, the drive mechanism is arranged along the door opening / closing direction, and includes a wire to which the door is attached, and a motor for moving the wire forward and backward in the door opening direction. The power slide door is also a power window regulator. As described above, there is provided a motor unit that includes a motor and a motor ECU that controls the motor and has a function of detecting foreign object pinching from the load state of the motor.

  On the other hand, the door of the power slide door has only two states, that is, a fully closed state or a fully open state. The operation signal output from the switch is only one type (open / close signal). When the door is in the fully open position, the motor ECU of the power slide door motor unit receives the open / close signal from the switch, The motor is controlled so that the door moves toward the fully closed position. Conversely, when the door is in the fully closed position, when the open / close signal is input from the switch, the motor is controlled so that the door moves toward the fully opened position. Further, when the motor is operating, control is performed so that the motor reverses when an open / close signal is input.

  Further, the capacitance sensor of the present embodiment is provided on the front end of the door moving in the closing direction or on the wall surface of the vehicle opening facing the front end of the door moving in the closing direction.

  Here, the electrical connection of the present embodiment will be described with reference to FIG. 7 which is a block diagram showing the electrical configuration of the present embodiment.

  As shown in FIG. 7, the sensor ECU 101 is provided on the input side of the motor ECU 105, and an open / close signal, a ground line (GND), and a capacitance sensor signal are input from the switch board 103. The sensor ECU 101 receives a door movement direction signal from the motor ECU 105.

  An opening / closing signal and a ground line (GND) are input to the motor ECU 105 via the sensor ECU.

  The sensor ECU 101 and the motor ECU 105 are connected to a power line (+ B) and a ground line (GND).

  Then, the sensor ECU 101 performs the operation shown in FIG. FIG. 8 is a flowchart of the sensor ECU. In the figure, when the sensor ECU 101 receives an opening / closing signal, the sensor ECU 101 takes in a door movement direction signal from the motor ECU 105 (steps 1 and 2). If the door is moving in the closing direction, the capacitance of the capacitance sensor is detected, and if the detected capacitance (Q) exceeds the set threshold (Q0), foreign matter is caught. In order to avoid the trapping of foreign matter, the open / close signal is turned on to move the door in the opening direction (steps 2, 3, and 4).

  The capacitance of the capacitance sensor in step 3 is detected only for a set time (T3: time required until the fully opened door moves to the fully closed state) (step 5). When the detection of the electrostatic capacity of the electrostatic capacity sensor has passed the set time, it is determined that the door window glass 15 is fully closed, and the operation ends.

  According to such a configuration, the following effects can be obtained.

 (1) A foreign object pinching detection device (capacitance sensor, sensor ECU 101) can be attached easily and inexpensively by retrofitting.

  Further, the sensor ECU 101 of the foreign object pinching detection device to be attached later detects the foreign object pinching based on the change in capacitance of the electrostatic capacitance sensor, so that a response is received from the foreign object pinching detection from the motor load state performed by the motor ECU 105 of the motor unit. It is possible to detect foreign object pinching quickly and in a short time.

  The present invention is not limited to the first to second embodiments. For example, it can be applied to an opening / closing mechanism such as a power sunroof, a power sunshade, and a power back door.

  Further, although the electrostatic capacity sensor is used as the sensor for detecting the foreign object, the present invention is not limited to this. For example, in the sensor having the cross-sectional structure shown in FIG. In other words, the outer electrode 55 and the inner electrode 57 may be brought into contact with each other to be electrically connected, thereby detecting a foreign object pinching.
