In this opening / closing body drive device, the position (opening) of the opening / closing body can be changed to a position desired by the occupant by operating the opening / closing switch once.

JP 2002-227518 A

  However, in the above-described opening / closing body drive device, it is difficult to remember the operation procedure, for example, it is necessary to operate an ignition switch that is generally located away from the opening / closing switch several times in order to change the predetermined amount. Even if I remembered it, the operation was complicated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide an opening / closing body drive device that can easily store the position of an opening / closing body desired by an occupant.

  An opening / closing body drive device that solves the above problems includes a motor for opening / closing the opening / closing body, a plurality of opening / closing switches for driving a motor provided in the driver's seat operation range and corresponding to the plurality of opening / closing bodies, and other functions. An opening / closing body drive device comprising a centralized switch unit including other function switches for performing and a control unit for driving the motor based on an operation of the opening / closing switch, wherein the control unit includes the other function switch Based on the fact that a preset operation in the centralized switch unit including this operation is performed, a storage process for storing the position of the opening / closing body at that time is performed.

  According to this configuration, the control unit performs a storage process for storing the position of the opening / closing body at that time based on a preset operation in the central switch unit including the operation of the other function switch. Can easily store the position of the opening / closing member desired by the user. That is, since the preset operation includes the operation of the other function switch near the open / close switch operated to drive the opening / closing body to open / close, the occupant can easily learn the preset operation, and the operation becomes easy. The position of the opening / closing member desired by the user can be easily stored. As a result, for example, if the opening / closing switch is automatically operated, the opening / closing body can be stopped at the stored position, and the position of the opening / closing body can be easily changed to a position desired by the occupant.

In the opening / closing body driving device, it is preferable that the other function switch includes an opening / closing body lock switch, and the preset operation includes an operation of the opening / closing body lock switch.
According to the configuration, the other function switch includes the opening / closing body lock switch, and the preset operation includes the operation of the opening / closing body lock switch. Therefore, some device may be operated by the preset operation. Can be avoided. For example, if the preset operation includes the operation of the door lock switch, there is a possibility that an extra operation such as the door lock actuator being operated by the preset operation may be performed. Can be avoided.

In the opening / closing body driving device, it is preferable that the control unit performs the storing process only when the vehicle is stopped.
According to this configuration, since the control unit performs the storage process only when the vehicle is stopped, for example, the storage process is performed even if an occupant mistakenly performs the preset operation while traveling. It is prevented. In addition, the occupant can stably store the opening / closing body and the centralized switch unit while viewing the opening / closing body and the centralized switch unit.

In the opening / closing body driving apparatus, it is preferable that the control unit performs the storing process only when the opening / closing body is within a pinching detection range.
According to this configuration, since the control unit performs the storage process only when the opening / closing body is within the pinching detection range, the opening / closing body is outside the pinching detection range (the range from the fully closed position to the almost fully closed position). At some time, the position of the opening / closing body is not stored. Therefore, for example, when the opening / closing switch is automatically operated, the opening / closing body stops at a position that is almost fully closed and slightly opened (for example, a position that slightly touches the weather strip). Such a thing disappears. Thereby, it can suppress that a passenger | crew misunderstands that the position of an opening / closing body exists in a fully closed position, for example.

  In the opening / closing body driving device, the control unit is configured to stop the opening / closing body at a stored position when an automatic operation of the opening / closing switch is performed or when a normal operation is continuously performed. It is preferable to drive the motor.

  According to this configuration, the control unit controls the motor so that the opening / closing body is stopped at the memorized position when an automatic operation of the opening / closing switch is performed or when a normal operation is continuously performed. In order to drive, the position of the opening / closing body can be easily changed to the stored position.

  In the opening / closing body drive device of the present invention, the position of the opening / closing body desired by the passenger can be easily stored.

Hereinafter, an embodiment of a power window device will be described with reference to FIGS.
As shown in FIG. 1, a window glass 2 as an opening / closing body is provided on the vehicle door 1 of the driver's seat so as to be movable up and down, and the window glass 2 is provided with an opening / closing body driving device 3 via a regulator (not shown). A motor M is drivingly connected.

  The opening / closing body driving device 3 includes the motor M, a microcomputer 4 as a control unit, a driving circuit 5 including a relay, and a Hall IC 6 as a position detection sensor. The microcomputer 4 is electrically connected to the drive circuit 5, the hall IC 6, the central switch unit 7 provided in the driver's seat operation range and provided on the vehicle door 1, and the vehicle ECU 8, and the hall IC 6, the central switch unit 7, The drive circuit 5 is controlled based on a signal from the vehicle ECU 8 to drive the motor M, and the window glass 2 is opened / closed (moved up and down). The Hall IC 6 detects a pulse signal corresponding to a change in the magnetic flux of the sensor magnet that rotates integrally with the rotating shaft of the motor M as position information of the window glass 2 and outputs it to the microcomputer 4.

  The central switch unit 7 includes an open / close switch 11 for driving a motor M corresponding to the window glass 2 of the driver's seat, and other (in this embodiment, the passenger seat, the rear seat on the driver's seat, the passenger seat side) Open / close switches 12 to 14 for driving a motor (not shown) corresponding to the window glass (with the rear seat) are provided. In addition, the central switch unit 7 includes an opening / closing body lock switch 15 that disables the operation of the opening / closing switches 11 to 14 (including the opening / closing switches provided in each seat) as other function switches for performing other functions, And a door lock switch 16 for locking each vehicle door including the vehicle door 1 of the driver's seat.

  Then, the microcomputer 4 drives the motor M based on the operation of the opening / closing switches 11 to 14, performs a pinching determination process as to whether or not the window glass 2 has been pinched, and when the pinching has been performed The motor M is driven and controlled to stop or reversely drive the window glass 2. Note that the microcomputer 4 is within the range where the window glass 2 is caught, specifically, the range from the fully closed position to the almost fully closed position (for example, a position close to the fully closed position where the window glass 2 slightly touches the weather strip). The pinching determination process is performed only when it is within the pinching detection range excluding.

  Further, the microcomputer 4 has a memory, and the position of the window glass 2 at that time (specifically, the position corresponds to the position) based on the fact that the preset operation in the central switch unit 7 including the operation of the other function switch is performed. Storage processing for storing the numerical values corresponding to the pulse signals from the Hall IC 6). The microcomputer 4 performs the storage process only when the vehicle is stopped. Further, the microcomputer 4 performs the storage process only when the window glass 2 is within the pinching detection range. The preset operation includes the operation of the opening / closing body lock switch 15, and the opening / closing body lock switch 15 is turned off twice within a preset time after the opening / closing body lock switch 15 is turned on. It is set to operate.

Specifically, as shown in FIG. 2, when the microcomputer 4 determines that the opening / closing body lock switch 15 is turned on, the microcomputer 4 performs the processes in and after step S1.
That is, when it is determined that the opening / closing body lock switch 15 is turned on, the microcomputer 4 determines in step S1 whether or not the vehicle is stopped based on a signal from the vehicle ECU 8, and determines that the vehicle is stopped. The process proceeds to step S2. If the microcomputer 4 determines that the vehicle is not stopped in step S1, the microcomputer 4 ends (ends) the process.

In step S2, the microcomputer 4 starts counting the timer and proceeds to step S3.
In step S3, the microcomputer 4 determines whether or not a preset time Tx (time Tx is 3 seconds, for example) has elapsed since the timer started counting, and the preset time has elapsed. If it is determined that there is not, the process proceeds to step S4. If the microcomputer 4 determines in step S3 that the preset time Tx has elapsed, the microcomputer 4 ends (ends) the process.

  In step S4, the microcomputer 4 determines whether or not the opening / closing body lock switch 15 has been turned off twice. When the microcomputer 4 determines that it has been turned off twice, the microcomputer 4 proceeds to step S5. If it is determined that the microcomputer 4 has not been turned off twice, the process proceeds to step S3.

  In step S5, the microcomputer 4 determines whether or not the window glass 2 is within the pinching detection range. When the microcomputer 4 determines that the window glass 2 is within the pinching detection range, the microcomputer 4 proceeds to step S6 and positions the window glass 2 at that time. A storage process is performed to store. If the microcomputer 4 determines in step S5 that the window glass 2 is not within the pinching detection range, the process ends (ends).

  When the microcomputer 4 performs an automatic operation (deep operation) of the open / close switch 11 or performs a normal operation (shallow operation) after the storage process is performed as described above, The motor M is driven so that the glass 2 is stopped at the position stored in the storing process.

Next, the operation of the power window device (opening / closing body driving device 3) will be described.
For example, when the occupant (driver) performs a normal operation (shallow operation) of the open / close switch 11 and moves the window glass 2 to a desired position (for example, a position opened about 10 cm) while the vehicle is stopped, When a preset operation in the central switch unit 7 including the operation of the lock switch 15 is performed, the position of the window glass 2 at that time is stored.

  That is, at this time, as shown in FIG. 3, when the opening / closing body lock switch 15 is first turned on and then the opening / closing body lock switch 15 is turned off twice before a preset time Tx has elapsed, The position of the window glass 2 at the time is stored. Since the opening / closing body lock switch 15 is alternately turned on and off each time it is pressed, the above-mentioned preset operation is performed by pressing it four times from the off state. .

  And then, for example, after moving the window glass 2 to another position (for example, a fully closed position), when the occupant (driver) performs an automatic operation of the open / close switch 11 (a deep operation for moving to the fully opened position), The motor M is driven so that the window glass 2 is stopped at the position stored by the microcomputer 4.

Next, the effect of the said embodiment is described below.
(1) Since the microcomputer 4 performs a storage process for storing the position of the window glass 2 at that time based on a preset operation in the centralized switch unit 7 including the operation of other function switches, The position of the window glass 2 desired by the user can be easily stored. That is, since the preset operation includes the operation of other function switches near the open / close switches 11 to 14 that are operated to open and close the window glass 2, the passenger can easily operate the preset operation. And the position of the window glass 2 desired by the user can be easily stored. As a result, for example, if the opening / closing switch 11 is automatically operated, the window glass 2 can be stopped at the stored position, and the position of the window glass 2 can be easily changed to a position desired by the passenger. become. Since the other function switch is an existing switch for performing another function, the number of parts does not increase as in the case where a new switch for storing the position of the window glass 2 is provided.

  (2) Since the other function switch includes the opening / closing body lock switch 15 and the preset operation includes the operation of the opening / closing body lock switch 15, some device may be operated by the preset operation. It can be avoided. For example, if the preset operation includes the operation of the door lock switch 16, there is a possibility that an extra operation such as the door lock actuator being operated by the preset operation may be performed. An extra operation can be avoided.

  (3) Since the microcomputer 4 performs the storage process only when the vehicle is stopped, for example, it is prevented that the storage process is performed even if an occupant mistakenly performs the preset operation while searching for the vehicle. The In addition, the passenger can stably store the window glass 2 and the centralized switch unit 7 while viewing the window glass 2 and the centralized switch unit 7.

  (4) Since the microcomputer 4 performs the storing process only when the window glass 2 is within the pinching detection range, when the window glass 2 is outside the pinching detection range (a range from the fully closed position to the almost fully closed position). The position of the window glass 2 is not stored. Therefore, for example, when the opening / closing switch 11 is automatically operated, the window glass 2 is stopped at a position where the window glass 2 is almost fully closed and slightly opened (for example, a position slightly touching the weather strip). It wo n’t happen. Thereby, it can suppress that a passenger | crew misunderstands that the position of the window glass 2 exists in a fully closed position, for example.

  (5) When the automatic operation (deep operation) of the open / close switch 11 is performed or when the normal operation (shallow operation) is continuously performed, the microcomputer 4 is stopped at the position stored in the window glass 2. Since the motor M is driven, the position of the window glass 2 can be easily changed to the stored position.

The above embodiment may be modified as follows.
In the above embodiment, the other function switch provided in the centralized switch unit 7 includes the opening / closing body lock switch 15, and the preset operation includes the operation of the opening / closing body lock switch 15. However, the present invention is not limited to this. Instead, the preset operation may include an operation of a function switch other than the opening / closing body lock switch 15. For example, the preset operation may include an operation of the door lock switch 16. In addition, when other function switches other than the opening / closing body lock switch 15 and the door lock switch 16 are provided in the centralized switch unit 7, the preset operation is performed (other than the opening / closing body lock switch 15 and the door lock switch 16. ) Operation of other function switches may be included.

  In the above-described embodiment, the preset operation is set to an operation of turning off the opening / closing body lock switch 15 twice within a preset time Tx after turning on the opening / closing body lock switch 15. However, the present invention is not limited to this and may be changed to another operation. For example, the preset operation may be set to an operation in which the open / close body lock switch 15 is turned off three times within a preset time Tx after the open / close body lock switch 15 is turned on. In addition, for example, the preset operation is set to an operation in which the open / close switch 11 is operated three times (in the opening direction or the closing direction) within a preset time Tx after the opening / closing body lock switch 15 is turned on. May be.

In the above embodiment, the microcomputer 4 performs the storage process only while the vehicle is stopped. However, the present invention is not limited to this, and the storage process may be performed even during traveling.
In the above embodiment, the microcomputer 4 performs the storage process only when the window glass 2 is within the pinching detection range. However, the present invention is not limited to this, and the memory is stored even when the window glass 2 is not within the pinching detection range. Processing may be performed.

  In the above embodiment, the microcomputer 4 stops at the position stored in the window glass 2 when an automatic operation (deep operation) of the open / close switch 11 is performed or when a normal operation (shallow operation) is continuously performed. However, the present invention is not limited to this. For example, the motor M may be stopped at the stored position only when an auto operation is performed. In the above embodiment, the automatic operation is described as a deep operation (the normal operation is a shallow operation). However, the automatic operation is an operation in which the opening / closing switch 11 is operated twice in a short time. When the operation is performed, the window glass 2 may be stopped at the stored position.
