BRIEF DESCRIPTION OF THE DRAWINGS The schematic block diagram of the system containing the power window motor in embodiment. The time chart for explaining the control mode in repellent sound generation operation.

Hereinafter, one embodiment of an opening and closing body control device, an opening and closing body drive motor, and an opening and closing body drive system will be described.
As shown in FIG. 1, a power window system 10 mounted on a vehicle includes a power window motor 11 for automatically opening and closing a window glass WG of a vehicle door DR, and a body communicably connected to the power window motor 11. And an ECU (Electric Control Unit) 21.

  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. Further, the power window motor 11 is attached to the inside of the vehicle door DR (specifically, between the inner door panel and the outer door panel constituting the vehicle door).

The motor main body 12 is rotationally driven based on the supply of drive power from the drive 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 an FET (Field Effect Transistor) 13b. The relay circuit 13a is a circuit that receives power supplied from a battery BT mounted on a vehicle and supplies and stops driving power for forward and reverse drive to the motor main body 12. The FET 13b, which is a semiconductor switching element, performs PWM (Pulse Width Modulation) control to adjust the drive power output from the relay circuit 13a. That is, the relay circuit 13a performs forward or reverse drive of the motor body 12 and its drive stop, that is, operation in the opening or closing direction of the window glass WG and its operation stop, and the FET 13b controls the rotation speed of the motor body 12 Change, ie change the operating speed of the window glass WG. The relay circuit 13 a and the FET 13 b are controlled by the P / W ECU 14.

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

  The P / W ECU 14 reverses the motor main body 12 in the power supply direction for, for example, normal rotation of the motor main body 12 to the relay circuit 13a in the case of the input of the open command signal. In the power supply direction for switching, it is possible to switch to a state (ON) in which power can be supplied. Further, in this case, the PWM control unit 14a of the P / W ECU 14 outputs a PWM control signal to the control terminal of the FET 13b, and switches the FET 13b to be on fixed (duty 100%) or on / off drive (variable duty) at a predetermined frequency. . When there is no input of the open / close command signal, the P / W ECU 14 stops the power supply to the motor body 12 to the relay circuit 13a (OFF), 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, ie, the position of the window glass WG, based on the rotational 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. Position information of the window glass WG is stored in a memory (not shown) in the P / W ECU 14 each time. Also, 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 main body 12 (the operation speed of the window glass WG). The slower the rotational speed of the motor body 12, the longer the cycle of the rotational pulse signal.

  The pinching processing unit 14c determines, based on the drive information (rotational speed, current value, and the like) of the motor main body 12, whether or not the foreign matter is pinched by the window glass WG in closing operation. When it is determined that the foreign object is caught, the pinch processing unit 14c controls the relay circuit 13a and the FET 13b to open the window glass WG by a predetermined amount, for example, so as to release the pinched foreign object. The pinching processing unit 14c may determine the inclusion of foreign matter generated between the window glass WG and the vehicle door DR during open operation, and in this case, the pinching processing unit 14c releases the trapped foreign matter. The relay circuit 13a and the FET 13b are controlled to close the window glass WG, for example, by a predetermined amount so as to enable it.

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

Next, the operation of the power window system 10 will be described.
The P / W ECU 14 adjusts the drive power (motor applied voltage) supplied from the drive circuit 13 to the motor main body 12 by PWM control of the FET 13 b while recognizing the open / close position of the window glass WG. This enables, for example, speed control of the window glass WG including so-called slow stop control, etc. in which the operation of the window glass WG is decelerated before the fully closed position.

Further, based on a predetermined operation of the open / close switch 20, the PWM control unit 14a executes a repellent sound generation operation that generates a repellent sound from the motor main body 12.
An example of an aspect of the repellent sound generation operation is shown in FIG. As shown in the figure, the P / W ECU 14 turns on the closing command (upward movement command) of the open / close switch 20 for a predetermined time (for example, for a predetermined time) in the OFF state of the relay circuit 13a (that is, the operation stop state of the window glass WG). When the predetermined number of times (three times in the example of FIG. 2) is made within several seconds, the repellent sound generation operation is started. At this time, the P / W ECU 14 maintains the off state of the relay circuit 13a and operates the on operation when the continuous on operation of the open / close switch 20 is within a predetermined specified time (for example, within 1 second). Count the number of times. And when the time of continuous on operation of opening and closing switch 20 reaches the specified time, it recognizes that the signal from opening and closing switch 20 by the operation concerned is a usual closing command signal, and motor main body 12 is usually It is driven to close the window glass WG.

  In the repulsive sound wave generation operation based on the predetermined operation of the open / close switch 20 described above, the P / W ECU 14 switches the relay circuit 13a to ON, and the PWM control unit 14a sets the motor applied voltage to a voltage value at the normal operation time of the window glass WG ( For example, PWM control is performed so that the voltage value V1 (for example, 0.5 [V]) smaller than 1.2 [V] is obtained. Also, at this time, the PWM control unit 14a prevents insects, which are set in advance, from the control frequency (PWM frequency) of PWM control from the frequency f1 (for example, 20 k [Hz]) at the time of normal operation of the window glass WG. Switch to repellent frequency f2. As a result, the motor main body 12 (specifically, an armature including a coil) vibrates at the repellent frequency f2, and a sound wave (repulsive sound wave) of the repellent frequency f2 is generated from the motor main body 12.

  Taking mosquitoes as an example of unpleasant pests, the frequencies at which the mosquitoes repel are approximately 6k to 9k [Hz] and approximately 16k to 18k [Hz]. By setting the repelling frequency f2 to a value within this range, repelling sound waves (sound waves of 6 k to 9 k or 16 k to 18 k [Hz]) repellent to mosquitoes are generated from the motor body 12 in the repelling sound wave generating operation. This makes it possible to keep mosquitoes away from the vehicle.

  When the time (operation continuation time) from the start of the repellent sound generation operation reaches the predetermined time T set in advance, the P / W ECU 14 stops the repellent sound generation operation, that is, turns off the relay circuit 13a. The motor applied voltage is set to 0 [v].

The operation of this embodiment will be described.
When a predetermined operation of the open / close switch 20 is performed in the operation stop state of the window glass WG, a repelling sound wave having a repelling frequency f2 to be repelled by an insect is emitted from the motor main body 12 to move the insect away from the vehicle It has become. The voltage applied to the motor at the time of this repellent sound generation operation is set to a voltage value V1 smaller than the voltage value at the time of normal operation (close operation or open operation) of window glass WG. It does not open and close. Further, as a condition for starting the repellent sound generation operation, regardless of the open / close position of the window glass WG, even if the window glass WG is fully closed, fully opened, or half opened, the repellent sound is generated based on predetermined operation of the open / close switch 20 The generation operation is to be performed.

The effects of this embodiment will be described.
(1) The PWM control unit 14a that adjusts the drive power supplied to the motor main body 12 by PWM control generates a repellent sound wave from the motor main body 12 as a control frequency of the PWM control as a frequency that the insects repel. Therefore, since the repellent sound wave having a frequency at which the insects repel is generated from the motor main body 12, the insect can be kept away from the vehicle. This makes it possible to suppress the entry of insects into the car when the wind glass WG is open, and also makes it easy to let insects in the car get out of the car. Further, since the repellent sound wave is generated from the motor main body 12 directly involved in the opening and closing operation of the window glass WG, an on-vehicle speaker or a special sound wave generator is used to generate the repellent sound wave. There is no need to provide separately, and repellent sound waves can be generated with a simple configuration.

  (2) The PWM control unit 14a generates repellent sound waves from the motor body 12 when the operation of the window glass WG is stopped. As a result, even if the voltage value V1 applied to the motor main body 12 at the time of the repellent sound generation operation is a value lower than the voltage value necessary for the operation of the window glass WG, the repellent sound wave can be generated from the motor main body 12 It is suitable.

  (3) The PWM control unit 14 a generates a repellent sound wave from the motor body 12 based on a predetermined operation of the open / close switch 20. As a result, by operating the open / close switch 20, it is possible for the user to generate the repellent sound wave at a desired timing.

  (4) The motor body 12 is provided in the vehicle door DR. For this reason, the repellent sound wave emitted from the motor main body 12 can be reflected inside the vehicle door DR (between the door panels, etc.), and can be released from the vehicle door DR to the inside and the outside of the vehicle interior. Can be kept away from The repellent sound wave reflected in the door panel of the vehicle door DR is directly emitted from the door panel to the inside and the outside of the vehicle compartment, and is also emitted from the gap of the belt molding and the like. It can be released effectively.

  (5) The repellent sound generation operation is performed based on the operation of the open / close switch 20 for opening / closing the window glass WG. Therefore, the repellent sound wave generating operation can be performed without separately preparing a switch for generating the repellent sound wave and a signal for generating the repellent sound wave.

The present embodiment can be modified as follows. The present embodiment and the following modifications can be implemented in combination with one another as long as there is no technical contradiction.
The control frequency (repulsive frequency f2) of the PWM control in the repellent sound generation operation may be set to a frequency at which a beast (for example, a cat or a rat) repels, or to a frequency at which both insects and beasts repel.

The repelling sound wave generation operation may be executed when the opening operation (downward movement command) of the open / close switch 20 is turned on a predetermined number of times within a predetermined time.
The repellent sound wave generating switch may be provided separately from the open / close switch 20, and the repellent sound wave generating operation may be performed based on the operation of the repellent sound wave generating switch.

  The repelling sound wave generation operation may be performed based on a predetermined operation of the operation switch provided on the portable device such as a wireless key (for example, the door lock switch is operated a predetermined number of times within a predetermined time). According to this, even when the user is outside the vehicle, it is possible to execute the repellent sound generation operation by the operation of the portable device. Therefore, for example, it is possible to generate repellent sound waves before the user gets into the vehicle, and to prevent insects and beasts from invading the vehicle interior when the vehicle door DR is opened.

  The P / W ECU 14, when the window glass WG is open, performs the predetermined operation (see the above embodiment) of the open / close switch 20 for starting the repellent sound generation operation, the whole window glass WG is It may be closed to the closed position and then the repellent sound generation operation may be performed.

  The repellent sound wave generating operation may be performed to generate the repellent sound wave from the motor body 12 during the opening operation or the closing operation of the window glass WG (that is, during the rotation driving of the motor body 12).

-The numerical value shown in the control frequency of PWM control, a motor applied voltage, etc. is an example, and you may change it suitably.
The position information of the window glass WG is obtained from the rotation sensor 15 of the motor body 12. However, for example, the position information of the window glass WG may be obtained with a current sensor capable of detecting the current ripple of the motor body 12.

  In the above embodiment, the drive circuit 13 and the P / WECU 14 are integrally provided to the power window motor 11. However, for example, the drive circuit 13 and the P / WECU 14 may be integrated on the open / close switch 20 side or electric components related to the vehicle door DR. You may provide in the door integrated ECU side to control.

Although not particularly mentioned in the above embodiment, the motor body 12 of the power window motor 11 may be a brushed motor or a brushless motor.
The drive circuit 13 includes the relay circuit 13a and the FET 13b. However, 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 FET, two semiconductor switching elements The half bridge type drive circuit used may be used.
