Description

  The present invention relates to an opening / closing body control device that opens and closes an opening / closing body of a vehicle and detects a foreign object being caught when the opening / closing body is closed.

  As an opening / closing body control device mounted on a vehicle, for example, there is a power window device. The power window device opens and closes a window glass of a window, which is an opening and closing body, by rotating a motor forward or backward.

  In the power window device, when a foreign object is caught in the window during the closing operation of the window glass, this is detected. Specifically, the load of the motor is detected based on the rotation speed of the motor and the current flowing through the motor, and the presence / absence of pinching is determined based on the result of comparing the amount of change of the load with a predetermined threshold.

  Further, for example, Patent Literatures 1 to 4 disclose techniques for preventing erroneous detection of pinching due to disturbance such as an impact when a vehicle door is closed and a vibration when the vehicle travels on a rough road.

  In Patent Document 1, when the ignition switch is in an off state and the door is in an open state, it is determined that there is a high possibility that the occupant gets out of the vehicle, and the pinching threshold is changed to a higher value.

  In Patent Document 2, the vibration intensity of the disturbance frequency component is detected, and when the intensity is higher than the false detection determination threshold, the pinching threshold is changed to a different value.

  Moreover, in patent document 3, when driving a window glass with a motor during driving | running | working, the drive speed of a motor is changed into a lower speed than usual. Further, the sandwiching threshold value is changed according to the change amount of the motor cycle with respect to the movement amount of the window glass.

  Further, in Patent Document 4, when the rate of change of the rotation period of the motor is larger than a predetermined value representing a disturbance load, the pinching threshold is corrected so that the pinching detection sensitivity becomes dull.

  Since the vehicle is parked while the engine is stopped, there is no vibration due to running or driving of the engine, and pinching is not erroneously detected by the vibration. In this case, if the pinching threshold is set to a loose value as in vehicle running, the pinching detection accuracy is low, and pinching cannot be detected quickly.

  Conversely, if the trapping threshold is set to a sensitive value while the engine is stopped, there is a high possibility that trapping will be erroneously detected if a disturbance such as vibration or shock is applied to the vehicle. . In addition, disturbances applied to the vehicle while the engine is stopped include, for example, vibrations and shocks due to surrounding construction and strong winds, vibrations and shocks that occur when loading on a ferry or parking in a multilevel parking lot, etc. There are various external factors.

  An object of the present invention is to improve the detection accuracy of foreign object pinching in the opening / closing body when the opening / closing body is closed, and to prevent erroneous detection of pinching due to disturbance.

An opening / closing body control device according to the present invention includes a control means for controlling driving of a motor that opens and closes an opening / closing body of a vehicle, a load detection means for detecting a load of the motor, and a load detection means that detects when the opening / closing body is closed. An opening / closing body comprising a determination means for comparing the amount of change in the load and a predetermined threshold to determine whether foreign matter is caught in the opening / closing body, and an engine state detection means for detecting a stop state of the engine of the vehicle The control device further includes vibration detection means for detecting the vibration of the vehicle, setting means for setting the threshold value to a normal value or a sensitive value that detects pinching more sensitively than the normal value, and transmitted from the remote controller. Receiving means for receiving a closing command for the opening and closing body . The control means controls the motor when the receiving means receives the closing command of the opening / closing body to close the opening / closing body, and controls the motor when the judging means determines that the object is caught. Then, the opening / closing body is stopped or opened after stopping. The setting means detects the engine stop state by the engine state detection means, and receives the opening / closing body closing command by the reception means. If the vibration detection means detects no vibration of at least one window, the threshold value is set to a sensitive value.

  According to the above, if the vehicle vibration is not detected in a state where the vehicle engine is stopped, the threshold value is set to a sensitive value. For this reason, even if a foreign object is caught in the opening / closing body, the jamming can be quickly detected by comparing the amount of change in the load of the motor with a sensitive value. In other words, the trapping can be detected by applying a lighter force than usual to the motor by the trapping of the foreign matter in the opening / closing body. Therefore, it is possible to improve the detection accuracy of the foreign object caught in the opening / closing body. Further, when the vibration of the vehicle is detected while the vehicle engine is stopped, the threshold value is set to a normal value. For this reason, even if a disturbance is applied to the vehicle while the engine is stopped, it is possible to prevent erroneous detection of pinching due to the disturbance by comparing the amount of change in the load of the motor with the normal value.

  According to the present invention, the opening / closing body control device further includes door state detecting means for detecting an open / closed state of the door of the vehicle, the setting means detects the engine stop state by the engine state detecting means, and receives means. If the closing command for the opening / closing body is received by the door and the door closing state is detected by the door state detecting means, the threshold value may be set to a normal value or a sensitive value based on the detection result of the vibration detecting means. Good.

  In the present invention, in the above opening / closing body control device, after the control means stops the closing operation of the opening / closing body, the setting means may set the normal value as the threshold value.

  Further, according to the present invention, in the above opening / closing body control device, the opening / closing body includes a window and a window glass of a power window provided on the door, and further includes operation means provided in the vehicle, and the control means includes a remote controller. The window glass may be opened / closed by driving a motor in accordance with a command from the control unit or an operating state of the operating means.

  According to the present invention, when closing the opening / closing body, it is possible to improve the detection accuracy of the foreign object pinching in the opening / closing body and to prevent erroneous detection of pinching due to disturbance.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  First, the configuration of the first embodiment will be described with reference to FIG. Hereinafter, the “power window” is expressed as “PW”.

  A PW control system 101 according to the first embodiment is mounted on an automobile and includes a PW control device 1, a remote controller 2, and other components 3 to 9.

  The PW control device 1 drives the motor 3 to operate the PW opening / closing mechanism 4 to open / close the window glass 6 of the window 5 provided on the door of the vehicle. The PW control device 1 is an example of the “opening / closing body control device” of the present invention. The window 5 and the window glass 6 are examples of the “opening / closing body” of the present invention.

  The PW control device 1 includes a control unit 11, a storage unit 12, a drive unit 14, a pulse detection unit 15, a PW operation unit 16, a reception unit 17, and an engine state detection unit 18.

  The control unit 11 includes a microcomputer and controls opening / closing of the window 5. The control unit 11 includes a load detection unit 11a, a pinch determination unit 11b, a threshold setting unit 11c, and a vibration detection unit 11d. The storage unit 12 includes a memory such as a ROM or a RAM.

  The drive unit 14 includes a circuit that drives the motor 3 in the normal rotation or reverse rotation. The rotary encoder 7 outputs a pulse synchronized with the rotation of the motor 3. The pulse detection unit 15 includes a circuit that detects a pulse output from the rotary encoder 7.

  The PW operation unit 16 includes a switch for operating opening and closing of the window 5 and is provided in the vehicle. The PW operation unit 16 is operated by the user and outputs a signal corresponding to the operation. The control unit 11 detects the operation state of the PW operation unit 16 based on the signal output from the PW operation unit 16. The PW operation unit 16 is an example of the “operation means” in the present invention.

  The receiving unit 17 includes a circuit that receives a signal transmitted from the remote controller 2. The receiving unit 17 is an example of the “receiving unit” in the present invention.

  The IG-SW (ignition switch) 8 is operated by the driver and outputs an on or off signal. The engine state detection unit 18 detects that the engine is in a drive or stop state based on an on / off signal output from the IG-SW 8. The engine state detection unit 18 is an example of the “engine state detection unit” in the present invention.

  The vibration sensor 9 is provided in the automobile and outputs a signal corresponding to vibration generated in the automobile body. The vibration detection unit 11 d of the control unit 11 detects the vibration of the automobile based on the output signal of the vibration sensor 9. The vibration detector 11d is an example of the “vibration detector” in the present invention.

  The remote controller 2 includes, for example, a passive entry system FOB key or a high-function mobile phone (for example, a smartphone), and is carried by a user. The remote controller 2 includes a control unit 21, a PW operation unit 22, and a transmission unit 23.

  The control unit 21 is composed of a microcomputer. The PW operation unit 22 includes a switch or key for operating opening / closing of the window 5. The transmission unit 23 includes a circuit that transmits a signal to the PW control device 1.

  When the user opens / closes the PW operation unit 22, the control unit 21 generates an open / close command corresponding to the operation state. The opening / closing command is transmitted by the transmission unit 23 and received by the reception unit 17 of the PW control device 1.

  The control unit 11 of the PW control device 1 controls the drive unit 14 according to the opening / closing command from the remote controller 2 received by the receiving unit 17 or the opening / closing operation state of the PW operation unit 16 to correct the motor 3. Roll or reverse. Thereby, the PW opening / closing mechanism 4 operates, the window glass 6 is lowered or raised, and the window 5 is opened / closed.

  At that time, the control unit 11 calculates the opening / closing movement amount of the window glass 6 and the rotation speed of the motor 3 based on the pulse detected by the pulse detection unit 15. And the control part 11 controls rotation of the motor 3 by the drive part 14 based on the calculation result. The load detector 11 a detects the load of the motor 3 based on the rotation speed of the motor 3. The control unit 11 is an example of the “control unit” in the present invention. The load detector 11a is an example of the “load detector” in the present invention.

  When the window glass 6 is closed (raised) in response to a closing command from the remote controller 2 or a closing operation of the PW operating unit 16, the pinch determining unit 11b detects the load of the motor 3 detected by the load detecting unit 11a. The amount of change is calculated. Then, the pinching determination unit 11b determines whether or not the foreign object is pinched in the window 5 by comparing the amount of change in the load of the motor 3 with a predetermined threshold. The pinch determination unit 11b is an example of the “determination unit” in the present invention.

  A normal value and a sensitive value are provided as the above-described sandwiching threshold values, and these values are stored in the storage unit 12. The normal value is set to a value that does not erroneously detect pinching by the pinching determination unit 11b even if the load on the motor 3 is affected by vibrations or shocks caused by external factors of the vehicle equipment or surroundings. The vibration and impact caused by the equipment of the automobile include, for example, vibration caused by running of the automobile and driving of the engine, and impact when the door is closed. Moreover, the vibrations and shocks caused by external factors around the automobile are, for example, vibrations and shocks caused by construction and strong winds, vibrations and shocks when parked in a ferry or a multilevel parking lot, and the like.

  The sensitivity value is set to a value that detects the trapping of foreign matter into the window 5 more sensitively than the normal value. That is, the sensitivity value is higher in sensitivity than the normal value, and the pinch detection is detected by the load of the small motor 3. In other words, the normal value is less sensitive than the sensitive value to detect pinching, and pinching is detected with a large load of the motor 3.

  The threshold setting unit 11c reads the normal value or the sensitive value from the storage unit 12 and sets the value in the pinching determination unit 11b, thereby changing the pinching determination threshold. The threshold setting unit 11c is an example of the “setting unit” in the present invention.

  Next, the operation of the PW control device 1 of the first embodiment will be described with reference to FIG. This operation is an operation when the window 5 is closed.

  First, the threshold value setting unit 11c reads a normal value from the storage unit 12 as a threshold value for pinching determination and sets it in the pinching determination unit 11b (step S1). Next, it is detected whether or not the engine is stopped (step S2). If the IG-SW 8 is in the on state, the engine state detecting unit 18 detects that the engine is not in a stopped state (in a driving state) (step S2: NO). Then, the control unit 11 determines whether or not the window 5 has been closed by the PW operation unit 16 in the vehicle (step S4).

  On the other hand, if the IG-SW 8 is in the off state, the engine state detecting unit 18 detects that the engine is in the stopped state (step S2: YES). And the control part 11 determines whether the close command of the window 5 was received from the remote controller 2 (step S3). Here, if the reception unit 17 does not receive the window 5 closing command from the remote controller 2 within a predetermined time (step S3: NO), the control unit 11 performs the window 5 closing operation using the PW operation unit 16 in the vehicle. It is determined whether or not there is (step S4).

  When the user closes the PW operation unit 16 in the vehicle, the control unit 11 determines that the PW operation unit 16 has closed the window 5 (step S4: YES), and drives the motor 3 by the drive unit 14. Then, the window glass 6 is closed (step S5).

  Then, the pinching determination unit 11b compares the amount of change in the load of the motor 3 detected by the load detection unit 11a with a threshold value (in this case, “normal value”) to determine whether or not foreign objects are pinched in the window 5. Determination is made (step S6).

  If the change amount of the load of the motor 3 is smaller than the threshold value, the pinching determination unit 11b determines that there is no pinching (step S6: NO). In this case, the control unit 11 determines whether or not the internal operation (PW operation unit 16) is out of the closing operation condition (step S7).

  For example, when the manual closing operation of the PW operation unit 16 performed in step S4 is continued until step S7, or after the PW operation unit 16 is automatically closed in step S4, the operation is continued until step S7. If not, the closing operation by the PW operation unit 16 is enabled in step S7. In addition to this, when it is detected from the amount of movement of the window glass 6 that the window glass 6 has not reached the fully closed position, the control unit 11 determines that it does not deviate from the closing operation condition of the internal operation ( Step S7: NO).

  Thus, if it does not deviate from the closing operation condition of the internal operation, the closing operation of the window glass 6 is continued by the control unit 11, and the pinching determination unit 11b determines the pinching again (step S6).

  On the other hand, for example, when the manual closing operation of the PW operation unit 16 performed in step S4 is canceled in step S7, or after the PW operation unit 16 is automatically closed in step S4, the process is performed until step S7. When operated in another opening / closing operation state, the closing operation by the PW operation unit 16 is invalidated in step S7. For this reason, it determines with the control part 11 having remove | deviated from the closing operation conditions of internal operation (step S7: YES). Moreover, for example, also when the window glass 6 has reached the fully closed position, the control unit 11 determines that it has deviated from the closing operation condition of the internal operation (step S7: YES).

  Thus, if it remove | deviates from the closing operation conditions of internal operation, the control part 11 will stop the drive of the motor 3, and will stop the closing operation of the window glass 6 (step S8). Then, each process is performed again from step S1.

  Further, if the load change amount of the motor 3 becomes equal to or greater than the threshold during the closing operation of the window glass 6, the pinch determination unit 11b determines that pinch is present (step S6: YES). In this case, after stopping the driving of the motor 3 and stopping the closing operation of the window glass 6, the control unit 11 reverses the motor 3 and executes the opening operation of the window glass 6 by a predetermined amount (step S9). . As another example, the closing operation of the window glass 6 may be stopped or the window glass 6 may be opened to the fully opened position. After step S9, each process is executed again from step S1.

  On the other hand, when the user closes the PW operation unit 22 of the remote controller 2 while the engine is stopped (step S2: YES), a command to close the window 5 is transmitted from the remote controller 2. When the reception unit 17 receives this window 5 closing instruction (step S3: YES), the threshold setting unit 11c reads out the sensitive value from the storage unit 12 as a threshold for pinching determination and sets it in the pinching determination unit 11b ( Step S10). And the control part 11 drives the motor 3 by the drive part 14, and performs the closing operation | movement of the window glass 6 (step S11).

  When the vibration sensor 9 and the vibration detection unit 11d detect a predetermined magnitude of vibration during the closing operation of the window glass 6, the control unit 11 determines that there is vibration in the automobile (step S12: YES). In this case, the threshold value setting unit 11c reads a normal value from the storage unit 12 as a threshold value for pinching determination and sets it in the pinching determination unit 11b (step S13).

  On the other hand, if the vibration sensor 9 and the vibration detection unit 11d do not detect a predetermined magnitude of vibration, the control unit 11 determines that there is no vibration in the automobile (step S12: NO), and uses it as a threshold for pinching determination. The sensitivity value set in step S10 is maintained.

  Then, the pinching determination unit 11b compares the amount of change in the load of the motor 3 detected by the load detection unit 11a with a threshold value, and determines whether or not foreign objects are pinched in the window 5 (step S14).

  When the load change amount of the motor 3 is equal to or greater than the threshold value, the pinching determination unit 11b determines that pinching is present (step S14: YES). In this case, after stopping the driving of the motor 3 and stopping the closing operation of the window glass 6, the control unit 11 reverses the motor 3 and executes the opening operation of the window glass 6 by a predetermined amount (step S15). . As another example, the closing operation of the window glass 6 may be stopped or the window glass 6 may be opened to the fully opened position. After step S15, the process returns to step S1, the normal value is set as the sandwiching determination threshold by the threshold setting unit 11c, and the subsequent processes are executed again.

  On the other hand, if the change amount of the load of the motor 3 is smaller than the threshold value, the pinching determination unit 11b determines that there is no pinching (step S14: NO). In this case, the control unit 11 determines whether or not the remote operation (remote controller 2) is out of the closing operation condition (step S16).

  For example, when the PW operation unit 22 of the remote controller 2 is manually closed, the reception unit 17 receives a command to close the window 5 from the remote controller 2 continuously or intermittently from step S3 to step S16. If yes, the close command for the remote controller 2 is valid in step S16. In addition, for example, when the PW operation unit 22 is automatically closed and a reception command for closing the window 5 is received from the remote control device 2 by the reception unit 17 in step S3, another open / close command is received from the remote control device 2 until step S16. Even when the remote control device 2 is not received, the close command for the remote controller 2 is valid in step S16.

  Thus, in addition to the effective closing command of the remote controller 2, the engine state detecting unit 18 detects that the engine is stopped and the window glass 6 has not reached the fully closed position. When this is detected, the control unit 11 determines that it does not deviate from the remote operation closing operation condition (step S16: NO). Then, the closing operation of the window glass 6 is continued by the control unit 11, the process returns to step S10, the threshold value setting unit 11c sets a sensitive value as a threshold for pinching determination, and the subsequent processes are executed again.

  On the other hand, for example, after the PW operation unit 22 of the remote controller 2 is manually closed and receives a window 5 closing command from the remote controller 2 in step S3, the closing command is continuously or intermittently received by step S16. If no signal is received by the receiving unit 17, the close command for the remote controller 2 is invalidated in step S16. In addition, for example, after the PW operation unit 22 is automatically closed and the window 17 is closed by the receiving unit 17 from the remote controller 2 in step S3, another open / close command is received from the remote controller 2 by step S16. Is also received, the close command of the remote controller 2 is invalidated in step S16. As described above, when the close command of the remote controller 2 is invalid, the control unit 11 determines that the remote operation close operation condition is not satisfied (step S16: YES).

  Further, for example, when the engine state detection unit 18 detects that the engine is in a driving state, or when it is detected that the window glass 6 has reached the fully closed position, the control unit 11 performs the remote operation closing operation. It is determined that the condition is not satisfied (step S16: YES).

  Thus, if it remove | deviates from the closing operation conditions of remote operation, the control part 11 will stop the drive of the motor 3, and will stop the closing operation of the window glass 6 (step S17). Thereafter, the process returns to step S1, the normal value is set as the sandwiching determination threshold by the threshold setting unit 11c, and the subsequent processes are executed again.

  According to the first embodiment, when the window glass 6 of the window 5 is closed by the closing command from the remote controller 2 in a state where the automobile engine is stopped, the vehicle is caught if vibration of the automobile is not detected. The determination threshold is set to a sensitive value. For this reason, even if a foreign object is caught in the window 5, the pinching can be quickly detected by comparing the amount of change in the load of the motor 3 with a sensitive value. In other words, the trapping can be detected by applying a lighter force than usual to the motor 3 due to the trapping of foreign matter in the window 5. Therefore, when the window glass 6 of the power window is closed by remote operation, it is possible to improve the detection accuracy of foreign object pinching in the window 5.

  In particular, when the window glass 6 is closed by remote operation, the operator does not always look at the window 5 and continues the operation without noticing that a foreign object has entered the gap of the window 5. There is a fear. However, in the first embodiment, the pinching threshold is set to a sensitive value, and pinching can be detected quickly, which is useful for the user.

  Further, since the automobile is in a parked state while the engine is stopped, disturbances such as running and vibration due to driving of the engine do not act. Therefore, even if the threshold value for judging the pinching is changed to a sensitive value when the engine is stopped, it is possible to prevent erroneous pinching detection due to disturbance such as vibration caused by running or driving of the engine.

  Further, in the case where the window glass 6 is closed by a remote operation while the engine is stopped, if a vibration of the automobile is detected, the threshold value for judging the pinching is set to a normal value. For this reason, even if vibrations or shocks due to various external factors are applied to the automobile, such as vibrations or shocks caused by surrounding construction or strong winds, vibrations generated on the ferry or when parking in a multilevel parking lot, etc., the motor 3 By comparing the amount of change in the load with the normal value, it is possible to prevent erroneous detection of pinching due to the disturbance.

  Further, while the window glass 6 is closed by remote operation while the engine is stopped, a process for switching the pinch detection threshold value to a normal value or a sensitive value according to the presence or absence of vibration of the vehicle, and based on the threshold value The process of determining whether there is pinching is repeatedly executed. For this reason, it is possible to further improve the pinching detection accuracy.

  Furthermore, after stopping the closing operation of the window glass 6, a normal value is set as a threshold for pinching determination. For this reason, when the window glass 6 is closed by remote operation or the window glass 6 is closed by internal operation in the engine driving state, the load change amount of the motor 3 and the normal value are By comparison, the presence or absence of pinching can be determined. And it becomes possible to prevent erroneous detection of pinching due to vibrations such as driving of an automobile or driving of an engine.

  Next, the structure of 2nd Embodiment is demonstrated, referring FIG. 3 and FIG.

  The PW control system 102 according to the second embodiment is mounted on an automobile and includes a PW control device 1 ′, a remote controller 2, and other components 3 to 6 and 8 as shown in FIG. 3.

  As shown in FIG. 4, a plurality of PW control devices 1 ′, motors 3, and PW opening / closing mechanisms 4 are provided so as to correspond one-to-one to a plurality of windows 5 and window glasses 6 provided in the automobile. ing. Each PW control device 1 ′ drives each motor 3 to operate each PW opening / closing mechanism 4 to open / close the window glass 6 of each window 5. Each PW control device 1 ′ is connected to a CAN (Controller Area Network) bus 20. The PW control device 1 ′ is an example of the “opening / closing body control device” of the present invention.

  In FIG. 4, the PW control device 1 ′ is provided in each window 5, but is not limited thereto. As another example, for example, a single PW control device is provided with a plurality of drive units for driving each motor for each window in forward rotation or reverse rotation, and a single control unit for controlling these drive units is provided. Also good.

  As shown in FIG. 3, the PW control device 1 ′ includes a control unit 11 ′, a storage unit 12, a CAN communication unit 13, a drive unit 14 ′, a PW operation unit 16, a reception unit 17, and an engine state detection unit 18. It is equipped.

  The control unit 11 ′ is composed of a microcomputer and controls opening and closing of the window 5. The control unit 11 'includes a load detection unit 11a', a pinch determination unit 11b, a threshold setting unit 11c, and a window vibration detection unit 11e.

  The CAN communication unit 13 includes a circuit for performing communication via the CAN bus 20. The drive unit 14 ′ includes a circuit that drives the motor 3 to rotate forward or backward by passing a current through the motor 3. The drive unit 14 ′ is provided with a current detection unit 14 a that detects a current flowing through the motor 3.

  The control unit 11 'calculates the rotation speed of the motor 3 based on the motor current detected by the current detection unit 14a, and controls the rotation of the motor 3 by the drive unit 14' based on the calculation result. The load detector 11 a ′ detects the load of the motor 3 based on the rotation speed of the motor 3. The control unit 11 ′ is an example of the “control unit” in the present invention. The load detector 11a 'is an example of the "load detector" in the present invention.

The window vibration detection unit 11e is a motor current detected by the current detection unit 14a or the control unit 11 ′.
The presence or absence of vibration of the window 5 to be controlled is detected based on the amount of change in the rotational speed of the motor 3 calculated by the above. The detection result of the window vibration detection unit 11e is transmitted to the other PW control device 1 ′ via the CAN communication unit 13 and the CAN bus 20. For this reason, the window vibration detection unit 11e receives the detection result of the window vibration detection unit 11e of the other PW control device 1 ′ via the CAN communication unit 13 and the CAN bus 20, and detects the vibration of the window 5 that is not controlled. Also detects presence or absence. The window vibration detector 11e is an example of the “vibration detector” in the present invention.

  Next, the operation of the PW control device 1 'according to the second embodiment will be described with reference to FIG. This operation is also an operation when the window 5 is closed.

  After the threshold value setting unit 11c sets a normal value as the pinch determination threshold value in the pinch determination unit 11b (step S1) and the engine is stopped (step S2: YES), the window 5 is closed from the remote controller 2. The command is received by the receiving unit 17 (step S3: YES). Then, the threshold value setting unit 11c sets the sensitive value as the pinch determination threshold value in the pinch determination unit 11b (step S10), and the control unit 11 drives the motor 3 to execute the closing operation of the window glass 6. (Step S11).

  When the window vibration detection unit 11e detects vibrations of a predetermined magnitude or more in all the windows 5 of the automobile, the control unit 11 ′ determines that there is vibration in all the windows 5 (step S12a: YES). ). In this case, vibration due to disturbance occurs in the entire vehicle, and if a sensitive value is used, there is a high possibility that pinching will be erroneously detected. Therefore, the threshold value setting unit 11c uses a normal value as a pinching determination threshold value. (Step S13).

  On the other hand, if the window vibration detection unit 11e does not detect vibration of a predetermined magnitude or more in at least one window 5, the control unit 11 ′ determines that there is no vibration of all windows 5 (step S12a: NO). ). In this case, vibration due to disturbance does not occur in the entire vehicle, and there is little possibility of erroneous detection of pinching even if a sensitive value is used. Therefore, the sensitive value set in step S10 is maintained as the threshold for pinching determination. Is done.

  Then, the pinch determination unit 11b compares the amount of change in the load of the motor 3 detected by the load detection unit 11a 'with a threshold value, and determines whether or not a foreign object is pinched in the window 5 (step S14). Moreover, the process of step S15 or S16 is performed according to the determination result of this pinching determination part 11b.

  According to the second embodiment, when the window glass 6 is closed by a remote operation while the engine is stopped, the threshold for judging the pinching becomes a sensitive value if vibration is not detected in at least one window 5. If vibration is detected in all the windows 5, the threshold for judging the pinching is set to a normal value. For this reason, when a disturbance is not applied to the automobile, even if a foreign object is caught in the window 5, the jamming can be detected quickly by comparing the amount of change in the load of the motor 3 with the sensitive value. And even if a vibration is erroneously detected in any of the windows 5, the vibration can be ignored and the pinching can be detected using a sensitive value. Further, when a disturbance is applied to the automobile, it is possible to prevent erroneous detection of pinching by comparing the amount of change in the load of the motor 3 with a normal value.

  Therefore, when the window glass 6 of the power window is closed by remote operation, it is possible to improve the detection accuracy of foreign object pinching into the window 5 and prevent erroneous detection of pinching due to disturbance.

  Next, the configuration of the third embodiment will be described with reference to FIG.

  A PW control system 103 according to the third embodiment is mounted on an automobile and includes a PW control device 1 ″, a remote controller 2, and other components 3 to 6, 8, and 10.

  A plurality of PW control devices 1 ″ are also provided so as to correspond one-to-one to a plurality of windows 5 and window glasses 6 provided in the automobile as in the PW control device 1 ′ (FIG. 4) of the second embodiment. Each PW control device 1 ″ drives each motor 3, operates each PW opening / closing mechanism 4, and opens / closes the window glass 6 of each window 5. Each PW control device 1 ″ is connected to the CAN bus 20. The PW control device 1 ″ is an example of the “opening / closing body control device” of the present invention.

  The PW control device 1 ″ includes a control unit 11 ′, a storage unit 12, a CAN communication unit 13, a drive unit 14 ′, a PW operation unit 16, a reception unit 17, an engine state detection unit 18, and a door state detection unit 19. ing.

  The door opening / closing sensor 10 is provided at each door of the automobile and outputs an on / off signal according to the open / closed state of the door. The door state detection unit 19 detects the open / close state of each door based on the on / off signal output from the door open / close sensor 10. The door state detector 19 is an example of the “door state detector” of the present invention.

  Next, the operation of the PW control device 1 ″ of the third embodiment will be described with reference to FIG. 7. This operation is also an operation when the window 5 is closed.

  After the threshold value setting unit 11c sets a normal value as the pinch determination threshold value in the pinch determination unit 11b (step S1), the control unit 11 'checks the state of the engine and the state of each door (step S2a). Here, when it is detected by the IG-SW 8 and the engine state detection unit 18 that the engine is not stopped, it is detected by the door opening / closing sensor 10 and the door state detection unit 19 that at least one door is not closed. In the case (step S2a: NO), the control unit 11 ′ determines whether or not the window 5 has been closed by the PW operation unit 16 in the vehicle (step S4).

  On the other hand, if it is detected that the engine is stopped and all the doors are closed (step S2a: YES), the control unit 11 ′ issues a command to close the window 5 from the remote controller 2. It is determined whether or not it has been received (step S3). Here, when the reception unit 17 receives a command to close the window 5 from the remote controller 2 (step S3: YES), the threshold setting unit 11c uses the sensitive value as the pinch determination threshold value. (Step S10). Then, the control unit 11 ′ drives the motor 3 to execute the closing operation of the window glass 6 (Step S <b> 11).

  During the closing operation of the window glass 6, the threshold value for pinching determination is set to a normal value (step S13) or step S10 according to the determination result (step S12a) of whether there is vibration in all windows 5. Maintain the sensitivity value set in. Further, the amount of change in the load of the motor 3 is compared with a threshold value to determine whether or not foreign matter is caught in the window 5 (step S14).

  And when it determines with there being no pinching (step S14: NO), control part 11 'determines whether it remove | deviated from the closing operation conditions of remote operation (step S16a). In this case, the remote operation closing operation conditions include that the remote controller 2 is closed, the engine is stopped, and the window glass 6 has not reached the fully closed position. , Including that all doors are closed.

  Therefore, when the close command of the remote controller 2 is valid, the engine is stopped, the window glass 6 has not reached the fully closed position, and all the doors are closed, the control unit 11 ′ is determined not to deviate from the remote operation closing operation condition (step S16a: NO).

  On the other hand, when the close command of the remote controller 2 is invalid, when the engine is in the driving state, when the window glass 6 has reached the fully closed position, or when at least one door is in the closed state, It is determined that the control unit 11 ′ has deviated from the remote operation closing operation condition (step S16a: YES).

  According to the third embodiment, when the window glass 6 is closed by remote operation with the engine stopped and all the doors closed, if no vibration is detected in at least one window 5, the pinch determination is made. The threshold value is set to a sensitive value. Further, if vibration is detected in all windows 5, the threshold for judging pinching is set to a normal value. For this reason, when a disturbance is not applied to the automobile, even if a foreign object is caught in the window 5, the jamming can be detected quickly by comparing the amount of change in the load of the motor 3 with the sensitive value. Further, when a disturbance is applied to the automobile, it is possible to prevent erroneous detection of pinching by comparing the amount of change in the load of the motor 3 with a normal value.

  Therefore, when the window glass 6 of the power window is closed by remote operation, it is possible to improve the detection accuracy of foreign object pinching into the window 5 and prevent erroneous detection of pinching due to disturbance.

  Also, when all the doors are closed, there is no disturbance due to the impact when the doors are closed. Therefore, even if the threshold for judging pinching is set to a sensitive value, the jamming may be erroneously caused by the disturbance. Without being detected, it is possible to quickly detect the foreign object caught in the window 5.

  Moreover, after stopping the closing operation of the window glass 6, a normal value is set as a threshold value for pinching determination. Therefore, when the window glass 6 is closed when the engine is driven or the door is open, or when the window glass 6 is closed by an internal operation, the load change amount and the normal value of the motor 3 are Thus, it is possible to determine the presence or absence of pinching. In addition, it is possible to prevent erroneous detection of pinching due to disturbance such as vibrations such as driving of an automobile or driving of an engine or an impact when a door is closed.

  The present invention can employ various embodiments other than those described above. For example, in the above embodiment, the example in which the threshold value for pinching is set to the normal value or the sensitive value according to the presence or absence of vibration during the closing operation of the window glass 6 by remote control is shown, but the present invention is only this. It is not limited to. In addition to this, for example, as shown in FIG. 8, even during the closing operation of the window glass 6 by an internal operation (operation of the PW operation unit 16), the sandwiching threshold is set to a normal value or a sensitive value depending on the presence or absence of vibration. May be set.

  FIG. 8 is a flowchart showing the operation of the PW control device according to the fourth embodiment. First, after setting a normal value as a threshold for pinching determination (step S1), the engine 5 is stopped (step S2: YES), and an instruction to close the window 5 is awaited. Here, when a window 5 closing command is received from the remote controller 2 or when there is a window 5 closing operation in the in-vehicle PW operation unit 16 (step S3a: YES), a sensitive value is set as a threshold for pinching determination. Set (step S10). And the motor 3 is driven and the closing operation of the window glass 6 is performed (step S11).

  If there is vibration of the automobile during the closing operation of the window glass 6 by remote operation or internal operation (step S12: YES), a normal value is set as a threshold for pinching determination (step S13). On the other hand, if there is no vibration of the automobile (step S12: NO), the sensitivity value set in step S10 is maintained as the threshold for determining pinching. Further, the amount of change in the load of the motor 3 is compared with a threshold value to determine whether or not foreign matter is caught in the window 5 (step S14).

  If there is no pinching (step S14: NO), it is determined whether or not the closing operation condition is not satisfied (step S16b). The closing operation condition in this case is that the closing command of the remote controller 2 or the closing operation of the PW operation unit 16 is effective, the engine is stopped, and the window glass 6 has reached the fully closed position. Not included.

  Therefore, when the closing command of the remote controller 2 or the closing operation of the PW operation unit 16 is effective, the engine is stopped, and the window glass 6 has not reached the fully closed position, the closing operation condition is satisfied. It is determined that it has not come off (step S16b: NO).

  On the other hand, if the closing command of the remote controller 2 or the closing operation of the PW operation unit 16 is invalid, the engine is in a driving state, or the window glass 6 has reached the fully closed position, the closing operation condition It is determined that it has deviated (step S16b: YES).

  As another example, in order to shift to step S3a in FIG. 8, in addition to the engine being in a stopped state (step S2), it may be a condition that all the doors are in a closed state (FIG. 7). (See step S2a). Further, instead of step S12 in FIG. 8, it may be determined whether or not there is vibration in all windows 5, and the threshold value for pinching may be set to a normal value or a sensitive value according to the determination result (FIG. 8). 7 step S12a). Further, it may be determined whether or not there are vibrations in the plurality of windows 5, and the threshold value for pinching may be set to a normal value or a sensitive value according to the determination result.

  Moreover, although the example which detected the drive / stop state of the engine based on the on / off state of IG-SW8 was shown in the above embodiment, this invention is not limited only to this. In addition to this, for example, based on an output signal from a sensor that detects vibration caused by driving the engine, an output signal from an ECU (electronic control unit) that controls the driving / stopping of the engine, the engine driving / stopping state May be detected.

  Moreover, although the example which detected the closed state of the door based on the output signal from the door opening / closing sensor 10 was shown in the above embodiment, this invention is not limited only to this. In addition to this, for example, when it is detected that the door is locked based on an output signal from a door lock detection sensor or switch, or an ECU, the door is determined to be closed. Also good.

  Furthermore, although the example which applied this invention to the PW (power window) control apparatus 1, 1 ', 1 "of the motor vehicle was given in the above embodiment, it is not restricted to this. The present invention can also be applied to an opening / closing body control device that controls an opening / closing operation of an opening / closing body of a vehicle, such as an opening / closing roof.
