Description

Opening / closing member control device

The present invention relates to an opening / closing member control device for controlling movement of an opening / closing member.

Patent Document 1 discloses a power window control device having a pinching prevention control. This power window control device rotates a motor in accordance with a user operation to a power window switch that is a user operation member, and performs a window glass closing operation or a full opening operation. The power window control device includes a hall sensor pair configured to generate a pulse each time the motor rotates once, and an ECU. This ECU detects the amount of movement of the window glass by counting the number of pulses of one hall sensor. Moreover, ECU detects the moving direction of a window glass by analyzing the pulse signal of a hall sensor pair. In this way, the ECU recognizes the current position of the window glass. Further, the ECU detects a change in the rotational speed of the motor, that is, a change in the moving speed of the window glass, from the interval (pitch) of the pulses output from the hall sensor. For example, when the window glass contacts an object while being closed, the moving speed of the window glass (rotational speed of the motor) is reduced, and the pulse interval is widened. The ECU detects the object by monitoring the pulse interval and prevents the object from being caught.

にも The movement speed of the window glass (motor rotation speed) also decreases when the window glass reaches the closed position. The ECU sets, for the window position, a sensitive zone that validates the sandwiching detection and a dead zone that invalidates the sandwiching detection so that the window glass closing is not detected. For example, if the ECU detects a decrease in the movement speed of the window glass when the window glass is moving in the closing direction within the sensitive band, the ECU determines that the pinch has occurred and moves the window glass (rotation of the motor). ). In this way, the object is prevented from being caught. On the other hand, if the ECU detects a decrease in the moving speed of the window glass while the window glass is moving in the closing direction within the dead zone, the ECU determines that the window glass has reached the closing position and moves the window glass. Stop (motor rotation). For example, when the upper end of the window glass is in contact with the glass run lip, the window glass subsequently moves in the closing direction, and further closing movement of the window glass is restricted by the door frame, the window glass reaches the closing position. It will be.

By the way, the dead zone is set immediately before the closing position, but the closing position may change upward or downward due to external environmental changes such as motor power supply voltage, ambient temperature, and glass run aging. Therefore, every time the window glass is closed, the ECU sets the stop position of the window glass as the origin of the window position, and sets the start position and end position of the dead zone based on the origin. For example, a position that is a predetermined distance away from the origin in the opening direction is set as the dead band start position. Regarding the end position of the dead zone, the ECU may set the stored origin as the end position of the dead zone, and preferably the margin distance for ensuring the closing from the stored origin to the closing direction. A position separated by a distance may be set as the dead zone end position. In this way, a region between the start position and the end position is set as a dead zone. That is, every time the window glass is closed, the position of the dead zone with respect to the glass run lip or the door frame is changed or updated. However, the distance from the start position of the dead zone to the end position (closed position), that is, the width of the dead zone, is a fixed value and is not changed regardless of changes in the external environment.

JP 2005-133449 A

FIG. 6 is a schematic diagram for explaining the dead band setting of the reference example. In FIG. 6, the area indicated by the screen tone is a dead zone. In the reference example, the distance from the start position to the end position of the dead zone is constant regardless of the ambient temperature. The position Ha is a position where the window glass 3 comes into contact with both

lips

10a and 10b of the glass run 10 and is sandwiched between the lips. The position Hb is the position of the top wall 10 c of the glass run 10. The position Hc is the position of the top wall of the door frame 11. As the hardness of the glass run 10 changes depending on the ambient temperature, the end position of the dead zone is changed to lower than that at room temperature when the temperature is low, and the end position of the dead zone is changed to higher than that at room temperature when the temperature is high. For this reason, at a low temperature, the distance from the position Ha of the

glass run lip

10a, 10b to the start position of the dead zone becomes short, and the margin for pinching detection becomes small. On the other hand, at a high temperature, the distance from the position Hc of the door frame 11 to the start position of the dead zone is shortened, and the margin for closing the window glass 3 is reduced.

For this reason, in the reference example, it was necessary to calculate a value for designating the dead zone by performing pinching detection and actual measurement of closing of the window glass for each vehicle. When a dead zone with an appropriate margin could not be set depending on the vehicle, it was necessary to change the pinching detection threshold.

An object of the present invention is to provide an opening / closing member control device that sets a dead zone so that pinching detection and closing can be appropriately performed regardless of the ambient temperature.
An opening / closing member control device according to one aspect of the present invention is configured to control movement of an opening / closing member based on rotation of a motor and detect pinching by the opening / closing member, and the moving speed of the opening / closing member. And a temperature estimation unit that estimates an ambient temperature based on a power supply voltage to the motor, and a dead zone setting unit that sets a dead zone according to the ambient temperature estimated by the temperature estimation unit, the opening / closing member control device If the opening / closing member is in the dead zone when the movement speed drop or movement stop of the opening / closing member is detected, it is determined that the opening / closing member has reached the closed position while invalidating the pinch detection.

According to this aspect, the dead zone setting means automatically adjusts the dead zone according to the ambient temperature estimated based on the moving speed and the power supply voltage. Thereby, a dead zone can be set so that pinch detection and closing can be performed appropriately regardless of the ambient temperature.

In some embodiments, the opening / closing member control device is used together with an elastic member with which the opening / closing member contacts before reaching the closed position, and the dead band is a start of a dead band that is a position on the most opening direction side of the dead band. From the position to the end position of the dead band which is the position closest to the closing direction of the dead band, and the dead band setting means is a closing position which is a movement stop position of the opening / closing member each time the opening / closing member is closed. A position is set as the origin, and the start position and end position of the dead zone are set based on the origin. The dead zone setting means is configured to change the ambient temperature before and after the ambient temperature estimated by the temperature estimation means. The deflection amount fluctuation amount of the elastic member is estimated, and the start position of the dead zone after the ambient temperature change is determined from the start position of the dead zone before the ambient temperature change. By a distance corresponding to the estimated amount of deflection variation moved or adjusted.

According to this aspect, assuming that the stiffness of the elastic member changes depending on the ambient temperature, the start position of the dead zone is moved or adjusted by a distance corresponding to the amount of change in the deflection of the elastic member. Thereby, a dead zone is set according to the ambient temperature, and both pinch detection and closing of the opening / closing member can be achieved.

In some aspects, when the ambient temperature estimated by the temperature estimation unit is lowered, the dead zone setting unit may change a deflection amount before and after the ambient temperature of the elastic member is lowered from the start position of the dead zone before the ambient temperature is lowered. The position shifted in the closing direction by the amount is set as the start position of the dead zone after the ambient temperature drops.

According to this aspect, the margin for pinching detection at a low temperature can be made equal to that at room temperature.
In some aspects, when the ambient temperature estimated by the temperature estimation unit rises, the dead zone setting unit changes a deflection amount before and after the ambient temperature rise of the elastic member from the start position of the dead zone before the ambient temperature rises. The position shifted in the opening direction by the amount is set as the start position of the dead zone after the ambient temperature rises.

According to this aspect, the margin for closing the opening / closing member at a high temperature can be made equal to that at a normal temperature.
In some embodiments, the opening / closing member control device changes or adjusts the moving speed of the opening / closing member to a constant speed before the opening / closing member reaches the closing position, and then moves the opening / closing member to the closing position at the constant speed. A speed control means for moving is provided.

According to this aspect, variation in the moving speed of the opening / closing member before closing due to the difference in the motor supply voltage can be suppressed. Thereby, the variation factor of the deflection amount of the elastic member can be limited only to the influence of the ambient temperature. Therefore, it can contribute to the setting of an appropriate dead zone.

According to some embodiments of the present invention, the dead zone can be set so that the pinching detection and the close-off can be appropriately performed regardless of the ambient temperature. Other aspects and advantages of the present invention will become apparent from the following description taken in conjunction with the drawings, which illustrate examples of the technical spirit of the present invention.

Hereinafter, an embodiment of the opening / closing member control device will be described.
As shown in FIG. 1, the power window control device 1, which is an example of an opening / closing member control device, controls the movement of the window glass 3 of the vehicle door 2. The window glass 3 corresponds to an opening / closing member.

The power window control device 1 includes an ECU 4 that controls the movement of the window glass 3. The ECU 4 can receive a signal requesting opening or closing of the window glass 3 from a user operation member (not shown) which can be a power window switch. The ECU 4 rotates the motor 5 in accordance with a signal from the user operation member. The ECU 4 performs a closing operation of the window glass 3 in response to the closing request, and performs a fully opening operation of the window glass 3 in response to the full opening request.

The power window control device 1 can include a plurality of sensors 5a. The sensor 5 a can include a rotation sensor for detecting the rotation of the motor 5 and a voltage sensor for detecting a power supply voltage of the motor 5. As shown in FIG. 1, the ECU 4 can receive the rotation sensor signals S1 and S2 and the voltage sensor signal S3. The rotation speed and rotation direction of the motor 5 correspond to the movement speed and movement direction of the window glass 3.

FIG. 2 shows an example of a rotation sensor. A magnet 7 is provided so as to surround the worm gear 6 that rotates integrally with the rotating shaft of the motor 5. The magnet 7 includes an S pole associated with the half circumference region of the worm gear 6 and an N pole associated with the remaining half circumference region of the worm gear 6. Two Hall sensors 8 and 9 are provided in the vicinity of the magnet 7. Each Hall sensor 8, 9 generates a pulse each time the motor 5 rotates by a predetermined angle. The pulse signals S1, S2 of the hall sensors 8, 9 are supplied to the ECU 4. The ECU 4 can detect the rotation speed and rotation direction of the motor 5, that is, the movement speed and movement direction of the window glass 3 based on the pulse signals from the hall sensors 8 and 9.

3 (a) and 3 (b) show the waveforms of the pulse signals S1 and S2 output from the hall sensors 8 and 9. FIG. In the example of FIG. 3A, each of the hall sensors 8 and 9 outputs one pulse each time the motor 5 makes one rotation. The ECU 4 counts the pulses output from the hall sensor 8 and detects the rotation angle of the motor 5, that is, the amount of movement of the window glass 3. As shown in FIG. 3B, the pulses of the Hall sensors 8 and 9 are shifted from each other. The ECU 4 determines that the window glass 3 is raised, that is, moved in the closing direction, when the pulse of the hall sensor 9 when the pulse of the hall sensor 8 rises is at the HI level. The rotation of the motor 5 at this time may be referred to as up rotation. On the other hand, when the pulse of the hall sensor 9 when the pulse of the hall sensor 8 rises is at the LO level, the ECU 4 determines that the window glass 3 is lowered, that is, moved in the opening direction. The rotation of the motor 5 at this time may be referred to as down rotation. Thus, the ECU 4 detects the rotation direction of the motor 5, that is, the moving direction of the window glass 3 based on the pulses of the hall sensors 8 and 9. Then, the ECU 4 recognizes the current position of the window glass 3 through detection of the movement amount and movement direction of the window glass 3.

Further, as shown in FIG. 4, the pulse interval (pitch) of the Hall sensor 8 corresponds to the rotational speed of the motor 5, that is, the moving speed of the window glass 3. The ECU 4 monitors the interval between pulses output from the hall sensor 8 and detects a change in the rotational speed of the motor 5, that is, a change in the moving speed of the window glass 3. For example, when an overload is applied to the window glass 3, the moving speed of the window glass 3 (rotational speed of the motor 5) is lower than normal. This decrease in speed is indicated by a wider pulse interval.

The pinching detection and closing detection of the power window control device 1 will be described. The ECU 4 sets, for the position of the window glass 3, a sensitive zone that enables pinching detection and a dead zone that invalidates pinching detection. For example, if the window glass 3 is in the sensitive band when the ECU 4 detects a decrease in movement speed or a movement stop of the window glass 3, the ECU 4 determines that pinching has occurred and moves the window glass 3 (rotation of the motor 5 ). On the other hand, if the window glass 3 is in the dead zone when the movement speed reduction or movement stop of the ECU 4 window glass 3 is detected, the ECU 4 determines that the window glass 3 has reached the closed position, and the window glass 3 (motor 5). To stop.

Explain the dead band setting according to the ambient temperature. The ECU 4 estimates the ambient temperature based on the moving speed (closing speed) of the window glass 3 and the power supply voltage (motor power supply voltage) to the motor 5. For example, when estimating the ambient temperature, the ECU 4 monitors both the closing speed and the motor power supply voltage based on the signals S1, S2, and S3, and the upper end of the window glass 3 contacts the

glass run lips

10a and 10b during the closing movement. Obtain the closing speed and motor supply voltage before starting. Then, the ECU 4 refers to, for example, a temperature table stored in the power window control device 1 or in the memory of the ECU 4 and selects the ambient temperature associated with both the obtained closing speed and the motor power supply voltage. The ECU 4 is temperature estimation means or includes temperature estimation means.

Further, the ECU 4 changes or adjusts the closing speed to a constant speed before the upper end of the window glass 3 contacts the

glass run lips

10a, 10b during the closing movement, preferably just before the position Ha, and the constant The window glass 3 is moved to the closing position at a speed. In general, the amount of deflection of the glass run 10 varies depending on both the hardness and the closing speed of the glass run 10. The hardness of the glass run 10 is affected by the ambient temperature, and the closing speed is affected by the motor power supply voltage and the ambient temperature. Therefore, the ECU 4 limits the variation factor of the deflection amount of the glass run 10 only to the influence of the ambient temperature by keeping the closing speed immediately before the closing is constant. The ECU 4 is speed control means or includes speed control means.

ECU4 memorize | stores the closed position which is the stop position of the closed window glass 3 as an origin, whenever it determines with the window glass 3 having reached the closed position. The ECU 4 may set the stored origin as an end position of the dead band, and sets a position shifted from the stored origin in the closing direction by a margin distance for ensuring the close-off as the end position of the dead band. May be. The ECU 4 adjusts the start position of the dead zone set last time by a method described later, and sets a region from the start position of the dead zone to the end position of the dead zone as the dead zone.

The adjustment of the start position of the dead zone will be described. When setting the dead zone, the ECU 4 adjusts the start position of the dead zone in accordance with the estimated ambient temperature. For example, when the ambient temperature has decreased since the dead zone was previously set, the ECU 4 changes the deflection amount of the glass run 10 before and after the ambient temperature is lowered from the previously set dead zone start position, that is, the dead zone start position before the ambient temperature is lowered. The position shifted in the closing direction by the amount is set as the start position of the dead zone after the ambient temperature drops. On the other hand, when the ambient temperature has increased since the dead zone was set last time, the EUC 4 changes the deflection amount of the glass run 10 before and after the ambient temperature rise from the previously set dead zone start position, that is, the dead zone start position before the ambient temperature rise. The position shifted in the opening direction by the amount is set as the start position of the dead zone after the ambient temperature rises. The ECU 4 refers to the deflection amount table in which the ambient temperature and the deflection amount of the glass run 10 are associated with each other, and the deflection amount corresponding to the ambient temperature estimated this time and the deflection amount corresponding to the ambient temperature estimated when the dead zone was set last time. Is calculated or acquired as the deflection amount variation. The ECU 4 is a dead zone setting unit or includes a dead zone setting unit.

Next, the operation of the power window control device 1 will be described.
As shown in FIG. 5, as the hardness of the glass run 10 (corresponding to an elastic member) changes depending on the ambient temperature, the closed position moves downward from the normal temperature at a low temperature, and the closed position at a high temperature. Move upwards at room temperature.

Here, it is assumed that the n-th closing operation of the window glass 3 is performed at room temperature, and then the n + 1-th closing operation of the window glass 3 is performed at a low temperature. In this case, the dead zone set when the n + 1th time, that is, the current closing operation is performed, is the glass run before and after the ambient temperature decrease from the dead zone set when the nth time, that is, the previous closing operation is performed. It is narrowed by 10 deflection amount fluctuations. For example, the white arrow in FIG. 5 indicates that the start position of the dead zone at a low temperature moves in the closing direction by the amount of deflection variation from the reference example in FIG. Thereby, the distance from the

glass run lip

10a, 10b to the start position of the dead zone is maintained equally at low temperature and normal temperature. Therefore, the margin for pinching detection is the same at low temperature and normal temperature.

Similarly, it is assumed that the n-th closing operation of the window glass 3 is performed at room temperature, and then the n + 1-th closing operation of the window glass 3 is performed at a high temperature. In this case, the dead zone set when the n + 1th time, that is, the current closing operation is performed, is the glass run before and after the ambient temperature rise from the dead zone set when the nth time, that is, the previous closing operation is performed. It is widened by 10 deflection amount fluctuations. For example, the white arrow in FIG. 5 indicates that the start position of the dead band at a high temperature moves in the opening direction by the amount of deflection variation from the reference example in FIG. As a result, the distance from the height Hc of the door frame 11 to the start position of the dead zone is maintained equally at high temperatures and normal temperatures. Accordingly, the margin for closing the window glass 3 is equal between the high temperature and the normal temperature.

As described above, according to the present embodiment, the following effects can be obtained.
(1) The ECU 4 automatically adjusts the dead zone after estimating the ambient temperature. Thereby, a dead zone can be set so that pinch detection and closing can be performed appropriately regardless of the ambient temperature.

(2) A dead zone is set assuming that the hardness of the glass run 10 changes depending on the ambient temperature. In particular, the ECU 4 adjusts the start position of the dead zone according to the amount of deflection of the glass run 10 that accompanies a change in ambient temperature. Thereby, a dead zone having a start position according to the ambient temperature is set, and both pinch detection and closing of the window glass 3 can be achieved.

(3) The margin for pinching detection at low temperatures can be made equivalent to that at room temperature.
(4) The margin for closing the window glass 3 at high temperature can be made equivalent to that at room temperature.
(5) The ECU 4 keeps the closing speed immediately before closing at a constant speed. For this reason, the dispersion | variation in the moving speed of the window glass 3 before closing due to the difference in motor power supply voltage is suppressed. Thereby, the fluctuation | variation factor of the deflection amount of the glass run 10 can be limited only to the influence of ambient temperature. Therefore, it can contribute to the setting of an appropriate dead zone.

The embodiment described above can be modified as follows.
The opening / closing member is not limited to the window glass of the vehicle door. In some examples, the opening and closing member may be downward in the closing direction and upward in the opening direction, such as a shutter of a building. In another example, the opening and closing member may be configured to move in a horizontal direction, such as a sliding door of a vehicle or an automatic door of a building. In still another example, the opening / closing member may be an opening / closing member such as a sunroof of a vehicle.

The ECU 4 may have a temperature estimation function using the closing speed and the power supply voltage as variables instead of or in addition to the temperature table. In this case, the ECU 4 is configured to calculate the estimated ambient temperature based on the acquired closing speed, the motor power supply voltage, and the temperature estimation function. The temperature table and / or the temperature estimation function may be determined by experiment or simulation.
