Description

  The present invention relates to a power window device that opens and closes a window glass by an occupant's operation.

  In recent years, for the purpose of improving the convenience of the vehicle, a so-called power window device is mounted on the vehicle that electrically raises or lowers the window glass using a DC motor or the like. In this power window device, when an operator operates an operation switch, an electronic control unit (Electronic Control Unit; hereinafter referred to as ECU) electrically connected to the operation switch is based on an input signal from the operation switch. Controls the rotation of the drive motor. Then, the rotation direction of the drive motor corresponding to the operation mode of the operation switch is determined by the ECU, and the rotation of the drive motor is converted into the reciprocating motion through the window drive unit, so that the window glass is raised or lowered. ing.

  However, in the conventional power window device, the input signal from the operation switch can be energized to the drive motor via the ECU when the ignition switch is on, and the input signal from the operation switch is not energized when the ignition switch is off. It was controlled by. Therefore, when the ignition switch is in the on state, the window glass can be opened and closed at any time by operating the operation switch. However, when the ignition switch is turned off, electricity is supplied to the drive motor of the window drive unit. Therefore, even if the operation switch is operated, the window glass does not operate.

  Thus, for example, when a passenger notices that the window glass has been forgotten to close after turning the ignition switch off, or when the vehicle engine must be stopped, such as when refueling a gas station, When I wanted to do this, I had to turn on the ignition switch again and open and close the window glass. Such an operation is very inconvenient for the passenger.

In contrast to the power window device as described above, a power window device having a so-called key-off timer function is disclosed (for example, see Patent Document 1). The power window device described in Patent Document 1 can be operated at all times when the ignition switch is in the on state, and when the ignition switch is turned off, within a predetermined time from when the ignition switch is turned off. In this invention, the occupant opens and closes the door of the driver's seat and further closes the door.
Japanese Patent Application No. 02-28665

  Here, the functional configuration of the power window device having the key-off timer function will be described with reference to FIGS. FIG. 6 is a functional block diagram of a power window device having a conventional key-off timer function. FIG. 7 is a flowchart showing the control (operation) of a power window control device having a conventional key-off timer function.

  A power window device having a key-off timer function includes an operation switch 2 that opens and closes a window glass 1 provided on a door 5a of a vehicle, a window drive unit 3 that opens and closes the window glass 1 by driving a drive motor 31, and an operation. The ECU 4 that controls the drive motor 31 based on the operation state of the switch 2 is provided. The ECU 4 includes an ignition switch detection sensor 6, a door open / close state detection sensor 5, and a timer 7.

  As shown in FIG. 6, the opening operation button is connected to the drive motor 31 via the opening operation circuit S1. The closing operation button is connected to the drive motor 31 via the closing operation circuit S2. When the ignition switch is in the on state, the ignition switch detection sensor 6 detects an ignition on signal. When this ignition-on signal is input to the ECU 4 via the OR circuit, the ECU 4 connects the opening operation circuit S1 for opening the window glass 1 and the closing operation circuit S2 for closing the window glass. When the opening operation circuit S1 and the closing operation circuit S2 are connected, the window glass 1 can be opened and closed by operating the opening operation button connected to the opening operation circuit S1 and the closing operation button connected to the closing operation circuit S2. When the ignition switch detection sensor 6 detects an ignition-off signal, the ignition-off signal is input to the ECU 4, and a timer in the ECU 4 starts counting the elapsed time (T) from when the ignition-off signal was detected.

  Here, when the door open / closed state detection sensor 5 detects a door closed state signal, the door open / closed state detection sensor 5 inputs the door closed state signal to the ECU 4, and the ECU 4 outputs the opening operation circuit S 1 and the closing operation circuit S 2. Connect. If the opening operation circuit S1 and the closing operation circuit S2 are continuously connected from the ignition-on state, the connection is continued as it is. Thereby, opening and closing operation of the window glass 1 is attained.

Thereafter, within a predetermined time (T _end ), for example, within 10 minutes from the detection of the ignition off signal, the door open / close state detection sensor 5 detects the first door opening signal after the ignition is turned off, and further detects the door closing signal. The door opening signal and the door closing signal detected next are sequentially input to the ECU 4. When this door closing signal is input, the opening operation circuit S1 in the ECU 4 and the closing operation are performed regardless of whether or not the elapsed time (T) from the detection of the ignition off signal is within the range of the predetermined time (T _end ). The connection of the operation circuit S2 is cut off. Further, regardless of whether the door is open or closed, if the elapsed time (T) from when the ignition-off signal is detected exceeds a predetermined time ( _Tend ), a signal indicating that the predetermined time ( _Tend ) has elapsed is input to the ECU 4. The connection of the opening operation circuit S1 and the closing operation circuit S2 in the ECU 4 is cut off. In other words, after the ignition is off, the window glass can be opened and closed while the driver's seat door is open within a predetermined time ( _Tend ), and then the driver's seat door is closed. It was impossible to open and close the window glass.

  Next, the control operation of the above-described power window device will be described. As shown in FIG. 7, when starting the execution of the control process, the ECU 4 of the power window device having the key-off timer function first determines whether or not the ignition switch is off (ST401). This is determined based on the ignition on / off signal from the ignition switch detection device.

  If the ignition switch is off, the process proceeds to ST402 to determine the operation of the timer. If the timer is not operating, the operation of the timer is instructed (ST403). When the timer is activated, the process proceeds to ST404, and it is determined whether or not the driver's seat door has been opened and closed. Whether the door is open or closed is determined based on an open / close signal from the door open / close state detection device.

If the opening / closing of the driver's seat door has not been performed, it is determined whether or not a predetermined time ( _Tend ) has elapsed (ST405). If the predetermined time has not elapsed, it is determined again in ST404 whether or not the driver's seat door has been opened and closed (ST404), and this is repeated thereafter.

  If the driver's seat door has been opened and closed (ST404), the operation of the power window is stopped (ST406). Then, the timer is reset (ST407) and ends.

  In the above-mentioned power window device, in addition to the elapse of a predetermined time after the ignition switch is turned off, the window glass can be opened and closed until the opening and closing of the door of the driver's seat is completed. If you accidentally touch the operation switch when opening the window, the window glass may open against the occupant's will. This is an event that tends to occur in a vehicle in which the door handle and the window glass operation switch are arranged close to each other.

  Such an event is troublesome because the ignition switch must be turned on again to close the window glass after the timer time has elapsed or the door is closed. In addition, it is not preferable from the viewpoint of crime prevention that the window glass is not noticed to be opened and is left in the half-open state. This may be the subject of the present invention.

  The present invention has been made in view of the problems as described above, and is within the elapse of a predetermined time by the timer function after the ignition switch is turned off, and before the door is opened and closed, the power window device is opened and closed. When the door is opened, the operation in the opening direction of the power window device is invalidated. Accordingly, it is possible to prevent the window glass from being forgotten to be closed due to an unintentional act contrary to the occupant's intention, and to provide a safer and more comfortable power window device.

  (1) An operation switch for opening and closing a window glass provided on a door of a vehicle, a window driving unit for opening and closing the window glass by a driving force of an electric motor, and moving the window glass in an opening direction based on the opening and closing operation A control unit that controls the driving force of the electric motor by transmitting an open signal to the electric motor and a closing signal for moving the window glass in a closing direction to the electric motor, and the control unit includes: A door opening / closing state detecting means for detecting the opening / closing state of the door; an ignition switch detecting means for detecting an on / off state of the ignition switch; and an elapsed time from the ignition off operation in which the ignition switch is turned off from the on state. Timer means for measuring time, and the control unit is at the time of the ignition-off operation A until the predetermined time elapses, when the door is open, a power window device, characterized in that for disabling the opening signal.

  (2) The power window device according to (1), wherein the control unit can arbitrarily change the predetermined time.

  (3) The control unit further includes a pinch detection unit that detects whether or not a foreign object is pinched between the window glass and the window frame, and the control unit includes a foreign object pinched by the pinch detection unit. The power window device according to any one of (1) and (2), wherein when the detection is detected, the control switch invalidates the input of the operation switch and outputs the opening signal for performing a predetermined opening operation.

  According to the invention of (1), the power window device is provided with a timer that counts the elapse of a predetermined time after the operation of turning off the ignition, and opens and closes the window glass within the predetermined time and before the door is opened and closed. In addition to being effective, the opening operation of the window glass is invalidated when the occupant opens the door, and the opening / closing operation of the window glass is invalidated when the door is further closed. Thereby, after the ignition is turned off, for example, when the occupant moves up and down, the operation switch is accidentally touched, and the inconvenience that the window glass is opened can be solved. Furthermore, it can be solved that the window glass falls into a half-open state against the intention of the occupant. In addition, if it is within a predetermined time, the window glass can be opened and closed in the state before the driver's door is opened. For example, in order to prevent the temperature inside the vehicle from rising in summer, the window glass is slightly opened. It is possible to open and close the window glass according to the intention of the passenger who wants to make it. Therefore, a safer and more comfortable power window device can be provided.

  According to the invention of (2), in addition to (1), a timer means that can arbitrarily set a predetermined time is used. Thereby, the timer effective time of the initial setting can be changed according to the use mode and preference of the occupant's vehicle. Such a timer setting function is considered to be effective, for example, for family use and commercial vehicles that require a long time to go up and down after the engine is turned off. Therefore, a safer and more comfortable power window device can be provided.

  According to the invention of (3), in addition to (1) and (2), a pinching detection means for executing a predetermined opening operation when a foreign object is pinched between the window glass and the window frame is used. Here, the predetermined opening operation refers to executing the opening operation of the window glass for a certain period of time or a certain amount. For example, an opening operation for 10 seconds may be executed, for example, an opening operation of 10 cm may be executed. In order to prevent the operation from being excessively large or small, it is preferable that a certain amount (for example, about 20 cm) of opening is secured and the minimum operation amount (for example, 5 cm) is opened. Moreover, it is good also as a structure including the operation | movement which stops a window glass after performing predetermined | prescribed opening operation | movement. As a result, in addition to when the ignition is turned on, even when the opening operation after the ignition is turned off is invalid, a foreign object, for example, a thing caught immediately by executing a predetermined opening operation even if a hand of a child or the like is caught Can be removed. Therefore, a safer and more comfortable power window device can be provided.

  According to the present invention, in addition to the timer function after the ignition switch is turned off, the operation in the opening direction of the window glass is invalidated when the door is opened. Thereby, it can prevent that a window glass falls into an open state contrary to a passenger | crew's intention after ignition switch-off. Further, the troublesome operation of closing the window glass by turning on the ignition switch again after the engine is turned off can be eliminated. Further, it is possible to prevent the vehicle from leaving the vehicle without noticing that the window glass is in a half-open state. Therefore, a safer and more comfortable power window device can be provided.

  In addition to the above, by including the pinching detection means, it is possible to immediately remove the pinched foreign matter even when the above control is executed, and it is possible to provide a safer and more comfortable power window device. .

  First, the configuration of the vehicle power window device 100 according to this embodiment will be described. FIG. 1 shows a door 5a on the driver's seat side of the vehicle according to the present embodiment. As shown in FIG. 1, a power window device 100 includes an operation switch 2 that opens and closes a window glass 1 that is attached to a door 5 a having a window and opens and closes the window, and an electric motor that outputs a driving force for opening and closing the window glass 1. The window drive unit 3 having the drive motor 31 as a control, and the control for outputting to the window drive unit 3 an open signal for moving the window glass 1 in the opening direction based on the opening / closing operation and a close signal for moving the window glass 1 in the closing direction. ECU4 as a part.

  Further, the ECU 4 includes a door open / close state detection sensor 5 that detects the open / close state of the door on the driver's seat side, an ignition switch detection sensor 6 that detects an on / off state of the ignition switch, and an ignition state that is output from the ignition switch. Based on the signal, it is determined whether or not a foreign object is sandwiched between the window glass 1 and the window 7 which measures the elapsed time from the ignition off operation when the ignition switch is turned off from the on state. It has a pinching detection device 8 for detection. Further, a battery is connected to the ECU 4, and power is supplied from here.

  The operation switch 2 is exposed and arranged on the inner surface side of the door 5a, and is connected to the ECU 4 by a control line. Further, it is connected to the ECU 4 through a power line, and power is supplied from a battery connected to the ECU 4. The operation button includes an opening operation button that lowers the window glass when pressed, and a closing operation button that raises the window glass when pulled. The opening operation button is connected to the drive motor 31 via the opening operation circuits S1a and S1b. The closing operation button is connected to the drive motor 31 via the closing operation circuit S2.

  An operator operates this operation button to open and close the window glass. As for the shape of the operation switch 2, for example, an opening operation part and a closing operation part are arranged at both ends of the push type or one operation button, and the window glass 1 is raised and lowered by pressing the opening operation part and the closing operation part. A seesaw type that can be opened and closed can be used. The present invention is particularly effective for a power window device having an operation switch of a type in which the window glass descends when pressed.

  The driver's seat operation switch 2 is provided with operation buttons that enable the passenger seat and the rear seat to be opened and closed. Furthermore, you may provide the main switch which can invalidate the on / off of the operation switch of all the seats other than the window by the side of a driver's seat. Note that the operation of the front and rear seat window glass in the driver's seat described above can be performed by connecting the in-vehicle network (see FIG. 5).

  The window drive unit 3 is disposed inside the door 5a on the driver's seat side, and includes a drive motor 31, a wire 32, a rail 33, and a carrier plate 34. A drum (not shown) is connected to the drive motor 31. The wire 32 goes around from the upper end of the rail 33 and is discharged from the lower end, and both ends of the wire 32 are wound around the drum in different directions. When the drum rotates forward, one end of the wire 32 is wound around the drum and the other end of the wire 32 is pulled out from the drum, so that the wire 32 moves up and down in the rail 33. The rail 33 is provided substantially vertically at the substantially center inside the door 5a of the vehicle, and a carrier plate 34 is slidably attached thereto. A wire 32 is fixed to the carrier plate 34, and the carrier plate 34 moves up and down on the rail 33 as the wire 32 moves up and down in the rail 33. The window glass 1 is fixed to the carrier plate 34. Therefore, the window glass is opened and closed by the vertical movement of the wire, and by the vertical movement of the carrier plate 34. In the present embodiment, the wire type is used for the window driving unit 3, but the means for driving the window glass 1 is not limited to this, and an arm type that opens and closes the window glass by an arm may be used. .

  The ECU 4 has a timer function. This timer function measures a predetermined time. The timer can arbitrarily change the setting of the predetermined time. The ECU 4 is connected to a door open / closed state detection sensor 5 and an ignition switch detection sensor 6. The ECU 4 controls the opening / closing operation of the power window device 100 by receiving the detection signal of the door open / close state and the on / off signal of the ignition switch.

  ECU4 is provided in a driver's seat, a passenger seat, and a backseat, respectively, and each ECU4 is connected in the network in a car (refer to Drawing 5). Thereby, operation of the window glass 1 of a passenger seat and a rear seat is attained in a driver's seat.

  The power window device 100 described above operates as follows.

  In the power window device 100, when an operator operates the operation switch 2, the ECU 4 electrically connected to the operation switch 2 performs rotation drive control of the drive motor 31 based on an input signal from the operation switch 2. First, the rotation direction of the output shaft of the drive motor 31 is determined according to the operation mode of the operation switch 2, and the rotation of the output shaft of the drive motor 31 is converted into a reciprocating motion through the window drive unit 3, thereby making the window glass. 1, the window glass 1 is configured to rise or fall.

  As shown in FIG. 2, when the ignition switch is in the on state, the ignition switch detection sensor 6 detects an ignition on signal. When this ignition-on signal is input to the ECU 4 via the OR circuit, the ECU 4 connects the opening operation circuit S1a for opening the window glass 1 and the closing operation circuit S2 for closing the window glass. When the opening operation circuit S1a is connected, the opening operation button of the operation switch 2 and the drive motor 31 of the window drive unit 3 can be energized (enabled). When the closing operation circuit S2 is connected, the closing operation button of the operation switch 2 and the drive motor of the window driving unit 3 can be energized (enabled). Here, by operating the opening operation button and the closing operation button of the operation switch 2, the drive motor 31 of the window drive unit 3 is energized, and the window glass 1 is opened and closed by the rotation of the drive motor 31.

  When the ignition switch detection sensor 6 detects an ignition-off signal, the ignition-off signal is input to the ECU 4, and a timer in the ECU 4 starts counting the elapsed time (T) from when the ignition-off signal was detected.

  Further, when the door open / closed state detection sensor 5 detects a door closed state signal, the door closed state signal is input to the ECU 4, and the ECU 4 connects the opening operation circuit S1a and the closing operation circuit S2. If the opening operation circuit S1a and the closing operation circuit S2 are continuously connected from the ignition-on state, the connection is continued as it is. Thereby, the opening / closing operation of the window glass 1 becomes effective.

Thereafter, when the door open / closed state detection sensor 5 detects the first door open signal after the ignition is turned off within a predetermined time (T ₃ ), for example, within 10 minutes from the detection of the ignition off signal, the door open state signal is input to the ECU 4. Then, the ECU 4 cuts off the connection of the open operation circuit S1a that has been connected. Thereby, the opening operation button is not connected to the drive motor, and the opening operation of the window glass 1 becomes invalid.

Further, when a door close signal is detected from the door open / close state detection sensor 5 within a predetermined time (T ₃ ), the door close signal detected after the first door open signal is input to the ECT 4. When this door closing signal is input, the ECU 4 determines whether the opening operation circuit S1a and the closing operation are performed regardless of whether or not the elapsed time (T) from the detection of the ignition off signal is within the predetermined time (T ₃ ). The connection of the operation circuit S2 is cut off, and the opening / closing operation of the window glass 1 becomes invalid.

Further, regardless of the open or closed state of the door 5a, ignition off when the signal transit time from the time of detection (T) has passed a predetermined time (T ₃₎ a predetermined time (T ₃₎ has elapsed the signal input to ECU4 Then, the ECU 4 disconnects the connection between the opening operation circuit S1a and the closing operation circuit S2, and the opening / closing operation of the window glass 1 becomes invalid.

Here, within a predetermined time (T ₃ ), when the door open / closed state detection sensor 5 detects the first door open signal after the ignition is turned off and the window glass opening operation becomes impossible, the window glass 1 When the pinch detection device 8 detects that a foreign object is pinched between the window glass 1 and the window frame while it is rising, a pinch detection signal is input to the ECU 4. When the pinching detection signal is input, the ECU 4 connects the opening operation circuit S1b based on this signal. Then, the drive motor is stopped, and the drive motor 31 is rotated by a certain amount in the opening direction to perform the opening operation.

  The detection of the pinching is performed based on a lock current generated when a foreign object is pinched between the window glass 1 and the window frame while the vehicle window glass 1 is moving up. Note that the pinching detection may be performed by detecting a decrease in moving speed (increase in load) from a change in the number of rotations (pulses) of the motor, and estimating and determining the pinching load.

  On the other hand, when the window glass 1 is closed, the opening and closing of the window glass 1 is restricted by the window frame, and a lock current is generated. Therefore, after the window glass 1 reaches a predetermined position where there is no risk of foreign objects being caught, it is necessary to close the window glass without taking a pinch detection measure even if a lock current occurs.

  Therefore, the ECU 4 knows the rotational position of the drive motor 31 based on the pulse count number of pulses emitted from the rotation detection unit. Then, the ECU 4 controls the drive motor 31 so that the pinch detection measure is not taken after the pulse count number reaches the predetermined count number of the window glass 1 by knowing the opening / closing position of the window glass 1. Note that the pulses emitted from the rotation detector are input to the ECU 4 with a phase difference.

  Next, the control sequence of the power window device will be described with reference to FIGS. As shown in FIGS. 3 and 4, when the ECU 4 of the power window device 100 starts executing the control process based on the ignition on / off signal, the ECU 4 determines whether or not the ignition switch is off (ST201).

If the ignition switch is off, the process proceeds to ST202, and the ECU 4 determines the operation of the timer 7. If the timer 7 is not operating, the ECU 4 instructs the operation of the timer 7 (ST203). Here, T ₀ shown in FIG. 4 is the time when the ignition off signal is detected, and indicates the time when the operation of the timer 7 is started.

  When the timer 7 is activated, the ECU 4 determines the setting of the flag (ST204). If the flag is not set, the process proceeds to ST205, and the ECU 4 determines whether or not the driver's seat door 5a is open. The opening / closing of the door 5a is determined based on an opening / closing signal from the door opening / closing state detection sensor 5.

Further, when the flag setting is confirmed in ST204, since the opening operation of the driver's seat door 5a is once performed, the process proceeds to ST207, and the detection of the closing signal of the driver's seat door 5a is determined. Here, T ₁ shown in FIG. 4 indicates when the open signal of the door of the driver's seat is detected.

If the opening signal of the driver's seat door 5a is not detected from the door opening / closing state detection sensor 5, the ECU 4 determines whether or not a predetermined time (T ₃ ) has elapsed in ST211. If the elapsed time (T) has not passed the predetermined time (T ₃ ) (T ₃ > T), the ECU 4 returns to ST204 again.

That is, before opening the driver's seat door 5a (T ₁ ) and until the elapsed time (T) exceeds the predetermined time (T ₃ ), the ECU 4 causes the opening operation circuit S1a and the closing operation circuit S2 to be in the closed state. Since it is connected, the opening / closing operation of the window glass becomes effective by operating the operation switch 2 (see FIG. 4).

If the opening signal of the driver's seat door 5a is detected from the door opening / closing state detection sensor 5 in ST205, the ECU 4 first sets a flag (ST206). Then, the ECU 4 determines the detection of the closing signal of the driver's seat door 5a (ST207). Here, T ₂ shown in FIG. 4 indicates when the close signal of the driver's side door is detected.

  If the door opening / closing state detection sensor 5 detects the closing signal of the driver's door 5a, the driver's seat door 5a is opened / closed after the ignition switch is turned off. The closing operation circuit S2 remains in the open state, and the opening / closing operation of the power window device is disabled (ST212).

  If the door opening / closing state detection sensor 5 does not detect the closing signal of the driver's seat door 5a, the opening operation circuit S1a is opened by the ECU 4 because the driver's seat door 5a is opened. The opening operation of the glass 1 becomes invalid (ST208).

That is, within the predetermined time (T ₃ ), the closing operation circuit S2 is in a closed state until the driver's seat door 5a is opened (T ₁ ) and until the driver's seat door 5a is closed (T ₂ ). Since it is connected, only the closing operation is valid.

Subsequently, when the door 5a is closed (T ₂ ), the connection between the opening operation circuit S1a and the closing operation circuit S2 is interrupted, so that the opening / closing operation of the window glass becomes invalid.

Further, if the predetermined time (T ₃ ) elapses with the door 5a of the driver's seat opened (T ₁ ), that is, the predetermined time (T ₃ ) before the door 5a is closed (T ₂ ). and thus passed _(T 3 _{<T 2),} since the closing operation circuit S2 during of T ₃ from T ₁ is connected to the closed state, by operating the operation switch 2, effective closing operation of the window glass It becomes.

Furthermore, if a predetermined time (T ₃ ) elapses before the driver's seat door 5a is opened (T ₁ ) (T ₃ <T ₁ ), the subsequent window glass opening / closing operation becomes invalid.

  In ST209, the ECU 4 determines whether or not a foreign object is sandwiched between the window glass 1 and the window frame. Whether or not a foreign object is pinched is determined by the pinching detection device 8. If it is determined that a foreign object is sandwiched between the window glass 1 and the window frame, a predetermined opening operation, that is, a certain amount of motor is driven in the opening direction (ST211). In this case, the ECU 4 connects the opening operation circuit S1b and drives the drive motor 31.

The pinch detection is performed during the closing operation of the window glass 1. Here, _{T 4} is the pinch detection, indicates when the ECU4 connects the opening operation circuit S1b, _{T 5} indicates when the connection opening operation circuit S1b is completed. As shown in FIG. 4, entrapment detection _is in T 3> _{T 2,} is performed between the previous _{T 2.}

In ST211, the ECU 4 determines whether or not a predetermined time (T ₃ ) has elapsed. If the elapsed time (T) has not passed the predetermined time (T ₃ ) (T ₃ > T), the ECU 4 confirms the setting of the flag again in ST204, and determines whether there is an open signal for the door 5a in ST205. Return to.

If the elapsed time (T) has passed the predetermined time (T ₃ ) (T ₃ <T), the process proceeds to ST212, and the operation of the power window is stopped. Then, the timer is reset (ST213) and ends.

  As described above, the power window device according to the present invention can prevent the window from being inadvertently opened during the door opening operation against the intention of the occupant after the engine is turned off. Thereby, the troublesomeness of turning on the ignition switch again and closing the window glass can be eliminated. Further, it is possible to prevent the vehicle from leaving without noticing that the window glass is in the half-open state.
