  In the above-described power window device, when the window glass or the weather strip is not properly installed, the window glass may come into contact with the weather strip before the window glass enters the mask section. At this time, if the above-described load information learning process is completed, the load due to the contact between the window glass and the weatherstrip is learned, so that the load due to the contact between the window glass and the weatherstrip even outside the mask section. Erroneous determination of entrapment hardly occurs. However, if the load information learning process has not been completed, such as during initial settings before shipment or when replacing parts, misjudgment of pinching due to contact between the window glass and the weatherstrip outside the mask section may occur. May occur.

  SUMMARY An advantage of some aspects of the invention is to provide an opening / closing member control device and a motor with a control device that can suppress erroneous determination of a foreign object being trapped.

  An opening / closing member control device for solving the above problem includes a control unit (5) for controlling driving of a motor (M) for opening / closing an opening / closing member (2) of a vehicle, and the control unit includes: In a section excluding a mask section having a predetermined length from the closed position (Pc) to the opening direction side thereof, a trapping determination process for determining occurrence of a foreign substance being trapped by the opening and closing member during the closing operation, and a closing operation of the opening and closing member. A load information learning process for storing load information for the position of the opening / closing member at the time, and using the load information obtained in the load information learning process for correction in the entrapment determination process. When the load information learning process is completed, the control unit sets a normal mask section (A1) as the mask section of the entrapment determination process, and completes the load information learning process. If not, it sets the elongate dilation mask section (A2) than the normal mask interval as the mask period of the pinch detection processing.

  According to the above aspect, when the load information learning processing has not been completed, an extended mask section longer than the normal mask section is set as a mask section of the pinch determination processing. For this reason, it is possible to suppress erroneous determination of entrapment in the vicinity of the fully closed position due to poor installation or the like. On the other hand, when the load information learning processing has been completed, a normal mask section that is narrower than the extended mask section is set as a mask section for the pinch determination processing. Therefore, it is not necessary to fix the mask section in a wide range in order to prevent erroneous determination, and it is possible to set a mask section in an appropriate range according to the situation.

According to a motor with a control device for solving the above-mentioned problems, the motor (M) for opening and closing the opening and closing member (2) is provided integrally with the opening and closing member control device.
According to the above aspect, in the motor with the control device integrally provided with the opening / closing member control device, it is possible to suppress the erroneous determination of the foreign object being caught.

FIG. 1 is a schematic configuration diagram of a power window device according to an embodiment. FIG. 4 is a schematic diagram showing a normal mask section and an extended mask section in the same embodiment. FIG. 4 is an explanatory diagram for describing a mode of a load information learning process in the same embodiment. FIG. 9 is a flowchart for explaining mask section setting processing in the same embodiment.

Hereinafter, an embodiment of an opening / closing member control device and a motor with a control device will be described.
As shown in FIG. 1, a window glass 2 as an opening / closing member is provided on a vehicle door 1 so as to be vertically movable, and a motor M of a power window device 3 is driven on the window glass 2 via a regulator (not shown). Are linked.

  The power window device 3 includes the motor M and a control device 4 including a power window ECU for controlling the motor M. The control device 4 includes, for example, a control unit 5 including a microcomputer, a drive circuit 6 including a relay, and a Hall IC 7 as a position detection sensor. The control unit 5 is electrically connected to the drive circuit 6, the hall IC 7, the operation switch 8 provided on the vehicle door 1, and the vehicle ECU 9, and based on signals from the hall IC 7, the operation switch 8, the vehicle ECU 9, and the like. The drive circuit 6 is controlled to drive the motor M to move the window glass 2 up and down. The power window device 3 of the present embodiment is configured such that the motor M, the Hall IC 7, the control device 4, and the like are housed in a single housing (not shown).

  The Hall IC 7 detects a pulse signal corresponding to a change in magnetic flux of a sensor magnet that rotates integrally with the rotation shaft of the motor M as position information of the window glass 2 and outputs the pulse signal to the control unit 5. The operation switch 8 is operated by a user to operate the signal for moving the window glass 2 up and the signal for moving the window glass 2 down. It can output a signal for driving the glass 2 to the open / close end position (so-called automatic function).

  The control unit 5 controls the driving of the motor M while recognizing the position of the window glass 2 with reference to the fully closed position Pc of the window glass 2 (or both the fully closed position Pc and the fully opened position). The fully closed position Pc is set in the initialization processing. In the initialization process, when the window glass 2 moved upward reaches the upper end of the movable range and the rotation of the motor M is restricted, the control unit 5 sets the restricted position as the fully closed position Pc.

  Further, every time the motor M is driven, the control unit 5 performs a load information learning process of writing speed data, which is load information for the position of the window glass 2, into the memory 11. At this time, the control unit 5 writes the speed data for each position obtained by dividing the entire range from the fully closed position Pc to the fully opened position of the window glass 2 (for example, divided into 256) into the memory 11.

  Further, the control unit 5 performs a pinch determination process of determining whether pinch has occurred based on a threshold value according to the speed data (load information). Then, for example, when the control unit 5 determines that the entrapment has occurred while the window glass 2 is being driven to the closed end position by the automatic function, the control unit 5 drives the motor M in the reverse direction to open the window glass 2. Direction to release the pinched state.

  The control unit 5 sets a predetermined section on the opening direction side (ie, the lower side) from the fully closed position Pc as a mask section in which the entrapment determination process is not performed. As the mask section of the present embodiment, a normal mask section A1 and an extended mask section A2 can be set. The upper end positions of the normal mask section A1 and the extended mask section A2 are the same at the fully closed position Pc, and the lower end position of the extended mask section A2 is lower (opening side) than the lower end position of the normal mask section A1. Is set. The lower end position of the expanded mask section A2 is set to be located several millimeters below the lower end (opening side end) of the weather strip 1a above the window frame of the vehicle door 1 (FIG. 2). reference).

Next, the setting process of the mask section by the control unit 5 will be described.
At the start of the closing operation of the window glass 2, the control unit 5 performs a mask section setting process for setting the mask section of the above-described pinch determination process.

  As shown in FIG. 4, in the mask section setting process, in step S1, the control unit 5 determines whether or not the initialization process has been completed, and when the initialization process has been completed, Move to step S2. If it is determined in step S1 that the initialization processing has not been completed, the mask section setting processing ends.

  In step S2, the control unit 5 determines whether or not the above-described load information learning processing has been completed. Here, when the load information learning process is completed, the process proceeds to step S3, and the mask section of the entrapment determination processing is set to the normal mask section A1. On the other hand, if the load information learning process has not been completed, the process proceeds to step S4, and the mask section of the entrapment determination processing is set to an extended mask section A2.

The operation of the present embodiment will be described.
For example, if a foreign object is caught in the window glass 2 while the window glass 2 is being closed by the automatic function based on the operation of the operation switch 8, it is determined by the control unit 5 that a foreign object has been caught. Then, the motor M is driven to rotate in the reverse direction, the window glass 2 is driven in the opening direction, and the sandwiched state is released.

  Here, as shown by a two-dot chain line in FIG. 2, when the wind glass 2 and the weather strip 1 a are improperly installed, the window glass 2 moves up and out of the normal mask section A1 (that is, the entrapment determination). In the processing section), the upper end of the window glass 2 may collide with the weather strip 1a.

  As shown in FIG. 3, when the rotation speed (actual speed) of the motor M decreases due to the collision between the window glass 2 and the weather strip 1 a, if the load information learning process is not completed, the actual speed of the motor M Is performed based on the speed information in accordance with. On the other hand, when the load information learning process is completed, the speed data calculated in the load information learning process corrects a decrease in the speed of the motor M due to the collision between the window glass 2 and the weather strip 1a. An entrapment determination process is performed based on the velocity data.

  Then, according to the control mode of the present embodiment, when the load information learning processing is not completed, the extended mask section A2 is selected as the mask section of the entrapment determination processing. As a result, even when the wind glass 2 and the weather strip 1a are poorly installed, the position where the wind glass 2 collides with the weather strip 1a is covered by the extended mask section A2. It is possible to prevent erroneous determination of entrapment at the time of collision with 1a.

  On the other hand, when the load information learning processing has been completed, the normal mask section A1 that is narrower than the extended mask section A2 is selected as the mask section for the pinch determination processing. Therefore, it is not necessary to fix the mask section in a wide range in order to prevent erroneous determination, and it is possible to set a mask section in an appropriate range according to the situation.

The effect of the present embodiment will be described.
(1) When the load information learning process is completed, the control unit 5 sets a normal mask section A1 as a mask section of the entrapment determination process. When the load information learning process is not completed, the control unit 5 sets a mask of the entrapment determination process. An extended mask section A2 longer than the normal mask section A1 is set as the section. As a result, it is possible to suppress erroneous determination of entrapment near the fully closed position Pc due to an improper installation of the window glass 2 or the weather strip 1a, and as a result, the openability of the window glass 2 is improved.

  If the load information learning process has been completed, the normal mask section A1 that is narrower than the extended mask section A2 is selected as the mask section for the pinch determination process. Therefore, it is not necessary to fix the mask section in a wide range in order to prevent erroneous determination, and it is possible to set a mask section in an appropriate range according to the situation.

This embodiment can be implemented with the following modifications. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
In the initialization processing of the above embodiment, when information on both the fully closed position Pc and the fully opened position of the window glass 2 is obtained, the control unit 5 sets the window glass 2 at the upper end and the lower end of the movable range in the initialization processing. The fully closed position Pc and the fully opened position are grasped by abutting each of them.

  In this case, as an aspect of the initialization processing, first, the window glass 2 is first moved upward to hit the upper end of the movable range, and then the window glass 2 is moved downward to strike the lower end of the movable range. The pattern and, conversely, a second pattern in which the window glass 2 is first moved downward to hit the lower end of the movable range, and then the window glass 2 is moved upward to strike the upper end of the movable range. Conceivable.

  As an aspect of the initialization processing, when the second pattern is selected, the load information learning processing at the time of the closing operation is performed during the upward movement after the window glass 2 is abutted against the lower end of the movable range. As a result, the load information learning process at the time of the closing operation is completed along with the completion of the initialization process.

  On the other hand, when the first pattern is selected as an aspect of the initialization processing, the load information learning processing at the time of the closing operation is not completed even if the initialization processing is completed. Therefore, when the first pattern is selected as the mode of the initialization processing, it is more effective to perform the mask section setting processing of the above embodiment.

  The control device 4 of the above-described embodiment is provided integrally with the motor M (that is, in the same housing). In addition, for example, the control device 4 is provided at a position separated from the motor M and separated from the motor M. M may be drive-controlled.
