Description

  The present invention relates to a power window motor for opening and closing a window glass provided in a vehicle door.

  2. Description of the Related Art Conventionally, a vehicle power window motor includes a motor body that opens and closes a window glass between a fully closed position and a fully opened position, and a control unit that opens and closes the window glass through the motor body based on the operation of the opening and closing switch. . In such a control section of the power window motor, so-called slow start control for opening the window glass at a low speed when starting from the fully closed position, or decelerating the window glass to be closed before reaching the fully closed position. There is what can perform so-called slow stop control (see, for example, Patent Document 1). In such a control unit that performs low-speed operation control (slow start / slow stop control) near the fully closed position, the voltage applied to the motor is controlled based on the position information of the window glass, so that a predetermined value from the fully closed position is obtained. The window glass is operated so that the operating speed in the section to the position is slower than the operating speed (normal speed) in the other sections. Thereby, generation | occurrence | production of the noise in drive systems, such as a window regulator and a speed-reduction mechanism, can be suppressed at the time of starting from the fully closed position of the window glass when the window glass reaches the fully closed position.

  By the way, in recent years, there is a demand for increasing the airtightness of the interior of the vehicle and a request for reducing the weight of the door in order to improve fuel efficiency. The door is difficult to close due to the atmospheric pressure inside the car (prone to become a half-door). As a solution to this, in recent power window motors, when the window glass is in the fully closed position or in the vicinity of the fully closed position, the window glass is opened by a predetermined width based on detection of the open state of the vehicle door (open / close switch There are some that can be opened). According to this, since the window glass is open, an air escape path in the vehicle can be made, so that the vehicle door can be easily closed (it is difficult to become a half door). In addition, after the vehicle door is closed, the window glass is closed based on detection of the closed state of the vehicle door (a closing operation not based on the operation of the opening / closing switch).

  However, when both the automatic operation control of the window glass at the time of opening and closing the door and the low speed operation control near the fully closed position as described above are simply combined, the window glass in the automatic operation control at the time of opening and closing the door is used. The operating speed becomes low in accordance with the operating speed of the window glass in the low speed operation control. For this reason, the operating time of the window glass in the automatic operation control at the time of opening and closing the door becomes long, and there is a possibility that the user may feel bothered.

  The present invention has been made to solve the above-mentioned problems, and its purpose is to provide both functions of automatic operation control of the window glass at the time of opening and closing the door and low-speed operation control near the fully closed position, An object of the present invention is to provide a power window motor capable of keeping the window glass operating time in the automatic operation control short.

  A power window motor that solves the above problems includes a motor body that opens and closes a window glass provided on a vehicle door between a fully closed position and a fully opened position, and the window glass that passes through the motor body based on an operation of an opening / closing switch. A power window motor having a control unit for opening and closing, wherein the control unit sets a first section from a set position set between the fully closed position and the fully open position to the fully closed position, Low-speed operation control in which the opening speed of the window glass based on the operation of the opening / closing switch is slower in the first section than in the second section, with the section of the first section on the fully open position side as the second section. Then, with the window glass positioned in the first section, the window glass is opened based on detection of the open state of the vehicle door, Automatic operation control for closing the window glass based on detection of a closed state of the vehicle door is executable, and at least one of the opening operation and the closing operation of the window glass based on the control of the control unit, The operating speed of the window glass in the automatic operation control is set faster than the operating speed of the window glass in the low speed operation control.

  According to this configuration, in the power window motor having both functions of automatic operation control of the window glass when the door is opened and closed and low speed operation control near the fully closed position, the operation time of the window glass in the automatic operation control when the door is opened and closed Can be kept short. As a result, it is possible to suppress the troublesomeness felt by the user for the operation of the window glass by the automatic operation control when the door is opened and closed.

  In the power window motor, in both the opening operation and the closing operation of the window glass based on the control of the control unit, the operation speed of the window glass in the automatic operation control is higher than the operation speed of the window glass in the low speed operation control. It is preferable that the setting is fast.

  According to this configuration, the operation time of the window glass in the automatic operation control at the time of opening and closing the door can be further reduced, and as a result, the troublesomeness felt by the user for the operation of the window glass in the automatic operation control can be further reduced. Can be suppressed.

  In the power window motor, the window glass operating speed in the automatic operation control is set faster than the window glass operating speed in the low speed operation control only in the window glass opening operation based on the control of the control unit. It is preferable.

  According to this configuration, the automatic operation control at the time of opening and closing the door is made only by making the operating speed of the opening operation of the window glass by the automatic operation control at the time of opening and closing the door faster than the operating speed of the opening operation of the window glass by the low speed operation control. The operating speed of the closing operation of the window glass due to is not faster than the operating speed of the closing operation of the wind glass by the low speed operation control. In other words, there is a concern that foreign matter may be caught between the vehicle window and the window glass in the closing operation, so that the foreign object is unlikely to be caught by reducing the closing speed of the window glass by automatic operation control when the door is opened and closed. The situation can be.

  According to the power window motor of the present invention, while having both functions of automatic operation control of the window glass at the time of opening and closing the door and low speed operation control near the fully closed position, the operation time of the window glass in the automatic operation control is shortened. Can be suppressed.

Hereinafter, an embodiment of a power window system including a power window motor will be described.
As shown in FIG. 1, a power window system 10 mounted on a vehicle includes a power window motor 11 that is mounted in a vehicle door DR and opens and closes a window glass WG of the vehicle door DR, and a power window motor 11. And an open / close switch 20 for driving. The power window system 10 also includes a body ECU (Electric Control Unit) 21 that is connected to the power window motor 11 so as to be communicable.

The power window motor 11 is configured by integrally assembling a motor body 12, a drive circuit 13, and a power window ECU (P / WECU) 14.
The motor body 12 is rotationally driven based on the supply of driving power from the driving circuit 13 and opens / closes the window glass WG in the vertical direction via a window regulator (not shown).

  The drive circuit 13 includes a relay circuit 13a and a field effect transistor (FET) 13b. The relay circuit 13a is a circuit that receives and supplies power from the vehicle-mounted battery BT and supplies and stops driving power for forward and reverse driving with respect to the motor body 12. The FET 13b, which is a semiconductor switching element, is subjected to PWM (Pulse Width Modulation) control and adjusts the driving power output from the relay circuit 13a. In other words, the relay circuit 13a performs forward or reverse driving of the motor body 12 and stops driving thereof, that is, operates in the opening or closing direction of the window glass WG and stops its operation, and the FET 13b controls the rotation speed of the motor body 12. Change, that is, change the operating speed of the window glass WG. Relay circuit 13 a and FET 13 b are controlled by P / WECU 14.

  The P / WECU 14 includes a PWM control unit 14a, a position / speed detection unit 14b, and a pinching processing unit 14c. The P / WECU 14 performs various controls related to the opening / closing operation of the window glass WG using the PWM control unit 14a, the position / velocity detection unit 14b, the sandwiching processing unit 14c, and the like. Here, when performing various controls, a rotation pulse signal synchronized with the rotation of the motor body 12 is input from the rotation sensor 15 to the P / WECU 14. The P / WECU 14 receives an open / close command signal from the opening / closing switch 20 provided in the vehicle door DR or the like.

  The P / WECU 14 feeds, for example, the motor main body 12 with respect to the relay circuit 13a when the open command signal is input, and reverses the motor main body 12 when the close command signal is input. The power supply direction is switched to a state where power can be supplied (ON). Further, in this case, the PWM control unit 14a of the P / WECU 14 outputs a PWM control signal to the control terminal of the FET 13b, and switches the FET 13b to be fixed on (duty 100%) or on / off driven at a predetermined frequency (variable duty). . When the input of the opening / closing command signal is lost, the P / WECU 14 stops (OFF) power supply to the motor main body 12 with respect to the relay circuit 13a, and the PWM control unit 14a switches the FET 13b off through the PWM control signal.

  The position / speed detector 14b detects the rotational position of the motor body 12, that is, the position of the window glass WG, based on the rotation pulse signal synchronized with the rotation of the motor body 12, specifically, based on the count of the edge of the pulse signal. I do. The position information of the window glass WG is stored in a memory (not shown) in the P / WECU 14 each time. Similarly, based on the rotation pulse signal, specifically, based on the length of the cycle of the pulse signal, the position speed detection unit 14b detects the rotation speed of the motor body 12 (the operating speed of the window glass WG). The slower the rotation speed of the motor body 12, the longer the period of the rotation pulse signal.

  When the rotational speed of the motor main body 12 that closes the window glass WG is reduced below the reference speed, the pinching processing unit 14c causes foreign matter to be caught between the window glass WG that is being closed and the vehicle door DR. It is determined that In this case, in the case where the operating speed of the window glass WG is changed midway according to the position of the window glass WG, the reference speed for determining the pinching is also changed as appropriate. When it is determined that the pinching has occurred, the pinching processing unit 14c controls the relay circuit 13a and the FET 13b so as to open the window glass WG, for example, by a predetermined amount so that the pinched foreign matter can be released.

  The P / WECU 14 adjusts the drive power (motor applied voltage) supplied from the drive circuit 13 to the motor body 12 by PWM control of the FET 13b while recognizing the opening / closing position of the window glass WG by the position / velocity detection unit 14b. The speed control of the opening / closing operation of the window glass WG is performed. Specifically, the P / WECU 14 performs speed control of the opening / closing operation of the window glass WG using a PWM command value map stored in advance in a memory (not shown). This PWM command value map is set with changes in the PWM command value (voltage command value) according to the position of the window glass WG. In this embodiment, individual PWM command values for the opening operation and the closing operation are used. A map is provided. And P / WECU14 determines the motor application voltage adjusted with PWM control of FET13b with reference to a PWM command value map based on the positional information on the window glass WG detected by the position speed detection part 14b.

  The P / WECU 14 is communicably connected to a body ECU 21 that is a host ECU via a vehicle communication system. Examples of the vehicle communication system include LIN (Local Interconnect Network) communication, CAN (Controller Area Network) communication, and the like. The P / WECU 14 acquires necessary various vehicle information from the body ECU 21.

Next, the operation (action) of the power window system 10 will be described.
The P / WECU 14 controls the operation of the window glass WG based on the open / close command signal output from the open / close switch 20 when the open / close switch 20 is operated, and a courtesy switch for detecting the open / closed state of the vehicle door DR. The window glass WG is controlled based on the detection signal from the door opening / closing detection unit 22.

First, the operation control (hereinafter referred to as normal operation control) of the window glass WG by the P / WECU 14 based on the operation (open or close command signal) of the open / close switch 20 will be described.
When the window glass WG is opened based on the opening command signal, the P / WECU 14 winds at a low speed when starting from the fully closed position Px (or near the fully closed position Px) as shown by the solid line in FIG. Slow start control for operating the glass WG is performed. Further, the P / WECU 14 performs slow stop control for reducing the operating speed of the window glass WG before reaching the fully open position Py. In FIGS. 2A and 2B, the position of the window glass WG is indicated as the window position.

  Here, a first setting position P1 and a second setting position P2 are set at predetermined positions between the fully closed position Px and the fully open position Py of the window glass WG. Of these two set positions, the one at the fully closed position Px is the first set position P1, and the one at the fully open position Py is the second set position P2. And, from the fully closed position Px to the first set position P1, the first section A1, between the first set position P1 and the second set position P2, the second section A2, and from the second set position P2 to the fully opened position Py. This is the third section A3.

  The P / WECU 14 gradually increases the operating speed of the opening operation of the window glass WG to the normal speed Sn in the first section A1, and opens the window glass WG at the normal speed Sn in the second section A2. In this embodiment, when the window glass WG is operated at the normal speed Sn, the PWM control unit 14a fixes the FET 13b on (duty 100%). That is, the PWM control unit 14a sets the motor applied voltage to the motor body 12 as the battery voltage. Then, the P / WECU 14 opens the window glass WG at a lower speed than the normal speed Sn in the third section A3. In the present embodiment, the opening speed of the window glass WG is gradually reduced from the normal speed Sn to a predetermined low speed (low speed Sa) from the second set position P2 to the intermediate position of the third section A3, The operating speed of the opening operation of the window glass WG is constant at the low speed Sa from the intermediate position to the fully open position Py.

  Similarly, when the window glass WG is closed based on the close command signal, the P / WECU 14 starts from the fully open position Py (or near the fully open position Py) as shown by the solid line in FIG. Sometimes slow start control is performed to operate the wind glass WG at low speed. Further, the P / WECU 14 performs slow stop control for reducing the operating speed of the window glass WG before reaching the fully closed position Px.

  Specifically, the P / WECU 14 gradually increases the operating speed of the closing operation of the window glass WG to the normal speed Sn in the third section A3, and closes the window glass WG at the normal speed Sn in the second section A2. . Then, the P / WECU 14 closes the window glass WG at a lower speed than the normal speed Sn in the first section A1. In the present embodiment, the closing speed of the window glass WG is gradually reduced from the normal speed Sn to the low speed Sa from the first set position P1 to the intermediate position of the first section A1, and then fully closed from the intermediate position. The operating speed of the opening operation of the window glass WG is constant at the low speed Sa from the position Px.

  As described above, the P / WECU 14 performs the low speed operation control (slow start / slow stop control) in the vicinity of the fully closed position Px and the fully open position Py in the normal operation control based on the operation of the opening / closing switch 20.

Next, the operation control of the window glass WG by the P / WECU 14 based on the detection signal from the door opening / closing detection unit 22 (hereinafter referred to as automatic operation control when the door is opened / closed) will be described.
When the P / WECU 14 receives a detection signal indicating that the vehicle door DR is in an open state from the door opening / closing detection unit 22 via the body ECU 21, the position of the window glass WG at that time (hereinafter referred to as position Ps). refer. At this time, the P / WECU 14 stores the position Ps of the window glass WG in the memory. When the position Ps of the window glass WG is within the section (fourth section A4) from the fully closed position Px to the third set position P3, the P / WECU 14 opens the window glass WG to the third set position P3. Operate. Note that the third setting position P3 is suitable for allowing the air inside the vehicle to escape when the opening amount of the window glass WG (the opening area formed by opening the window glass WG) is closed. The third setting position P3 of the present embodiment is set closer to the fully closed position Px than the first setting position P1. That is, the fourth section A4 is set to be included in the first section A1. The third setting position P3 is preferably set to a position moved about 10 mm to 40 mm from the fully closed position Px to the fully open position Py side.

  In the opening operation of the window glass WG by this automatic operation control, the P / WECU 14 performs speed control of the opening operation of the window glass WG using a PWM command value map for automatic operation control stored in advance in a memory (not shown). Do. Specifically, the P / WECU 14 opens the window glass WG at the normal speed Sn until the window glass WG reaches the third set position P3 from the position Ps as shown by a two-dot chain line in FIG. Let When the position Ps is the fully closed position Px, the P / WECU 14 opens the window glass WG at the low speed Sa only in a slight section from the fully closed position Px (a section about 1 mm from the fully closed position Px). Then, the window glass WG is opened at a normal speed Sn until the third set position P3 is reached. Thus, the average speed of the opening operation in the fourth section A4 by the automatic operation control (the average value of the fourth section A4 in the PWM command value map for automatic operation control) is the normal operation control (slow start control) described above. Is set to be faster than the average speed of the opening operation in the fourth section A4 (average value of the fourth section A4 in the PWM command value map for normal operation control).

  As described above, the P / WECU 14 opens the window glass WG at the normal speed Sn from the position Ps to the third set position P3 on the basis of the detection signal indicating that the vehicle door DR is in the open state. The window glass WG is stopped at the 3 setting position P3. Thereby, a sufficient opening amount of the window glass WG is ensured, and when the vehicle door DR is closed, it is difficult to become a half door.

  Then, when the P / WECU 14 receives a detection signal indicating that the vehicle door DR is closed and the vehicle door DR is in the closed state from the door opening / closing detection unit 22 via the body ECU 21, the P / WECU 14 receives the window glass WG at the third set position P3. To the position Ps. At this time, the P / WECU 14 performs speed control for closing the window glass WG using a PWM command value map for automatic operation control stored in advance in a memory (not shown). Note that the PWM command value map for automatic operation control is provided separately for the opening operation and the closing operation.

  In the closing operation of the window glass WG by this automatic operation control, the P / WECU 14 moves the window glass WG from the third set position P3 to the position Ps at the normal speed Sn as indicated by a two-dot chain line in FIG. Close with. When the position Ps is the fully closed position Px, the P / WECU 14 operates the closing speed of the window glass WG in a section immediately before the fully closed position Px (a section of about 1 mm immediately before the fully closed position Px). Is the low speed Sa. Thus, the average speed of the closing operation in the fourth section A4 by the automatic operation control (the average value of the fourth section A4 in the PWM command value map for automatic operation control) is the normal operation control (slow stop control) described above. Is set to be faster than the average speed of the closing operation in the fourth section A4 (average value of the fourth section A4 in the PWM command value map for normal operation control).

  Note that the automatic operation control at the time of opening and closing the door as described above is such that the position Ps of the window glass WG at the time when the P / WECU 14 receives the detection signal that the vehicle door DR is in an open state is within the fourth section A4. It is executed when That is, when the position Ps is not within the fourth section A4 (that is, the window glass WG is on the fully open position Py side with respect to the third setting position P3), the window glass WG is already sufficiently open. The automatic operation control at the time of opening and closing the door is not executed.

Next, characteristic effects of the present embodiment will be described.
(1) Low-speed operation control in the fourth section A4 including the fully-closed position Px (slow start / slow in normal operation control). It is set to be faster than the respective operating speeds of the opening operation and the closing operation of the window glass WG by the stop control. According to this, the window glass in the automatic operation control at the time of opening and closing the door is provided with both functions of the automatic operation control at the time of opening and closing the door and the low speed operation control (slow start / slow stop control) near the fully closed position Px. The working time of the WG can be kept short. As a result, it is possible to suppress the troublesomeness felt by the user for the operation of the window glass WG by the automatic operation control when the door is opened and closed.

  (2) The P / WECU 14 opens the window glass WG at a low speed Sa in a slight section at the time of starting from the fully closed position Px in the automatic operation control at the time of opening and closing the door. Further, the P / WECU 14 decelerates the operating speed of the closing operation of the window glass WG from the normal speed Sn to the low speed Sa immediately before the fully closed position Px in the automatic operation control at the time of opening and closing the door. According to this, at the time of starting from the fully closed position Px, which is the mechanical lock position, or at the time of reaching the fully closed position Px, while keeping the operation time of the window glass WG in the automatic operation control at the time of opening and closing the door short. Generation of abnormal noise in the drive system such as a window regulator or a speed reduction mechanism can be suppressed as much as possible.

In addition, you may change the said embodiment as follows.
In the automatic operation control at the time of opening and closing the door in the above embodiment, the window glass WG is closed from the third setting position P3 to the position Ps based on the detection of the closed state of the vehicle door DR. The WG may be closed from the third setting position P3 to the fully closed position Px.

  In the above-described embodiment, the P / WECU 14 opens the window glass WG at a low speed Sa in a small section at the time of starting from the fully closed position Px in the automatic operation control at the time of opening and closing the door, but is not limited thereto. The window glass WG may be opened at the normal speed Sn from the fully closed position Px. In the above embodiment, the P / WECU 14 reduces the operating speed of the closing operation of the window glass WG from the normal speed Sn to the low speed Sa immediately before the fully closed position Px in the automatic operation control at the time of opening and closing the door. Not limited to this, the window glass WG may be closed at the normal speed Sn up to the fully closed position Px.

  -The aspect of the deceleration and the speed increase in 1st and 3rd area A1, A3 in the normal operation control of the said embodiment can be changed suitably. For example, in the slow start control in the first section A1, the opening speed of the window glass WG from the fully closed position Px to the intermediate position in the first section A1 may be constant at the low speed Sa. Further, for example, in the slow stop control in the first section A1, the operating speed of the window glass WG may be reduced until reaching the fully closed position Px without providing a constant speed section before the fully closed position Px. .

  In the automatic operation control at the time of opening and closing the door according to the above embodiment, the speed control using the PWM command value map for automatic operation control is performed. However, the present invention is not limited thereto, and the duty of the PWM control at the time of the automatic operation control is predetermined. The value (for example, duty 100%) may be constant. According to this, since the PWM command value map for automatic operation control becomes unnecessary, the amount of memory used can be suppressed. Further, the control can be simplified by not adjusting the duty by the FET 13b in the automatic operation control at the time of opening and closing the door.

  In the above embodiment, the window glass WG opening and closing operation speeds by the automatic operation control at the time of opening and closing the door are in the fourth section A4 by the low speed operation control (slow start / slow stop control in the normal operation control). The window glass WG is set to be faster than the opening speed and closing speed of the window glass WG, but is not particularly limited thereto.

  For example, only the opening operation of the window glass WG by the automatic operation control at the time of opening and closing the door may be set faster than the operation speed of the opening operation of the window glass WG in the fourth section A4 in the low speed operation control. In this case, the closing operation of the window glass WG by the automatic operation control at the time of opening and closing the door is preferably speed-controlled (that is, operated at a low speed) based on a PWM command value map for normal operation control, for example. According to this, since there is a concern that foreign matter is caught between the window glass WG in the closing operation and the vehicle door DR, by closing the window glass WG by automatic operation control at the time of opening and closing the door, It can be set as the situation where the foreign object pinching does not arise easily. Therefore, the operation time can be kept short in the opening operation of the window glass WG by the automatic operation control at the time of opening and closing the door while realizing a preferable operation from the viewpoint of foreign object pinching by the window glass WG.

  When only one of the opening operation and closing operation of the window glass WG by the automatic operation control at the time of opening and closing the door is set faster than the operation speed of the window glass WG in the fourth section A4 in the low speed operation control, The open / close operation time of the window glass WG in the automatic operation control (total time of the opening operation and the closing operation) is longer than that in the above embodiment. That is, as in the above-described embodiment, the opening speed and closing action speed of the window glass WG by the automatic action control when the door is opened and closed are the opening speed and closing action of the window glass WG in the fourth section A4 by the normal action control. By setting each operation speed faster than each operation speed, the operation time of the window glass WG in the automatic operation control at the time of opening and closing the door can be further reduced. As a result, the troublesomeness felt by the user for the operation of the window glass WG by the automatic operation control when the door is opened and closed can be further suppressed.

  In the above embodiment, the third setting position P3 is set closer to the fully closed position Px than the first setting position P1, but not limited to this, the same position as the first setting position P1 or the first setting position P1. May also be provided on the fully open position Py side.

  In the normal operation control and the automatic operation control at the time of opening / closing the door in the above embodiment, the P / WECU 14 performs speed control (PWM control) of the window glass WG opening / closing operation using the PWM command value map. In addition, for example, speed control (PWM control) using an arithmetic expression may be performed.

  The drive circuit 13 is composed of the relay circuit 13a and the FET 13b, but the configuration of the drive circuit is not limited to this. For example, a full bridge type drive circuit using four semiconductor switching elements such as FETs and two semiconductor switching elements The used half bridge type drive circuit may be used. Moreover, in the said embodiment, although P / WECU14 adjusts a motor applied voltage by PWM control, it is not specifically limited to this.

  In the power window motor 11 of the above embodiment, the motor main body 12 and the P / WECU 14 are integrally assembled. However, the present invention is not limited thereto, and the P / WECU 14 is configured separately from the motor main body 12. Also good.
