Description

  The present invention relates to an opening / closing body control device for controlling opening / closing of an opening / closing body such as a power tailgate or a power slide door of a vehicle.

  In recent years, an increasing number of vehicles can be automatically opened and closed by operating a switch provided with a tailgate, a sliding door, and the like of the vehicle near the driver's seat. When opening and closing this type of tailgate or the like, it is necessary to check the safety of the surroundings. Conventionally, however, it has been entrusted to the occupant's visual observation, and a technique for checking the safety more reliably and easily is desired.

By the way, as a safety confirmation device at the time of reverse of the vehicle, there is known a device in which an image captured by a rear camera provided at the rear of the vehicle body is displayed on the display of the navigation device when the shift lever is set to the reverse position (for example, a patent Reference 1).
Japanese Patent Laid-Open No. 2006-27307

  Although it is conceivable to use the safety confirmation device for backward confirmation when the tailgate is opened, it is necessary to operate the shift lever to the retracted position before opening the tailgate. It becomes complicated.

  In addition, even if a switch dedicated to confirming the rear for displaying the image captured by the rear camera on the display is provided, this switch must be operated before the tailgate is opened, which again makes the operation complicated. . Furthermore, a space for installing a new switch is also required, resulting in an increase in cost.

  Therefore, the present invention is advantageous in all aspects of operation, space, and cost, and provides an opening / closing body control device that can easily and reliably confirm the safety around the opening / closing body.

In the opening / closing body control device according to the present invention, the following means are employed in order to solve the above-mentioned problems.
Switches (for example, a slide door switch 5 and a tailgate switch 7 in the embodiments described later) provided in the vehicle interior and an opening / closing body (for example, a power in the embodiments described later) provided in the vehicle based on the operation of the switches. An actuator that opens and closes the sliding door 3 and the power tailgate 4 (for example, a sliding door actuator 6 and a tailgate actuator 8 in the embodiments described later) and an imaging means that can image the periphery of the opening and closing body (for example, an embodiment described later). The side camera 10, blind spot camera 11, rear camera 13) in the example, display means (for example, a display device 14 in an embodiment to be described later) capable of displaying an image picked up by the image pickup means, and the switch have the first pattern. the opening and closing by the actuator when in engineered As well as an image captured by the imaging means without performing the opening or closing control displayed on said display means, said switch is operated again in a second pattern after completion of the operation of the first pattern An opening / closing body control device comprising , as a condition, control means for performing opening or closing control of the opening / closing body by the actuator (for example, a control device in an embodiment described later).
With this configuration, when the switch is operated in the first pattern, an image around the opening / closing body is displayed on the display means, so that the occupant continues to open and close the opening / closing body by viewing this image. It can be determined whether or not this is a favorable situation. One switch can display an image on the display means or operate the actuator. Further, since the video can be displayed on the display means or the actuator can be operated by different operation patterns for the switch, the operability is improved.

Further, on condition that the switch is operated again by the second pattern after completion of the operation of the first pattern, since the opening or closing control of the opening and closing member by the actuator, open or closed closing body Before doing so, the passenger can be surely urged to confirm safety around the opening / closing body.

According to the first aspect of the present invention, when the switch is operated in the first pattern, the image around the opening / closing body is displayed on the display means, and the occupant continues to open and close the opening / closing body by viewing this image. Since it is possible to determine whether or not this is a preferable situation, safety confirmation can be performed easily and reliably.
In addition, since one switch can display an image on the display means and operate the actuator, the cost can be reduced by sharing the switch.
Further, since the video can be displayed on the display means or the actuator can be operated by different operation patterns for the switch, the operability is improved.

In addition, since the occupant can be urged to confirm safety around the opening / closing body before the opening / closing body is opened or closed , safety is further improved.

  A door mirror 9 is provided on the door on the driver side and the door 2 on the passenger seat of the vehicle 1, and as shown in FIG. 1, a side camera (imaging means) 10 and a blind spot camera are provided at the bottom of the door mirror 9. (Imaging means) 11 is installed. The side camera 10 is installed toward the rear side of the vehicle body, and the blind spot camera 11 is installed downward. As shown in FIG. 2, the imaging range S1 of the side camera 10 is on the side of the door 2 and the power slide door 3. The blind area camera 11 has an imaging range S2 set in front of the door mirror 9.

A rear camera (imaging means) 13 is installed on the rear surface of the power tailgate 2 and in the vicinity of the license plate 12. The rear camera 13 is installed toward the rear of the vehicle body, and as shown in FIG. 2, the imaging range S3 of the rear camera 13 is set to the rear and side rear of the vehicle body.
In addition, the side camera 10, the blind spot camera 11, and the rear camera 13 can be comprised from a CCD camera, a CMOS camera, etc.

  As shown in FIG. 3, the vehicle 1 includes a display device (display device) 14 of a navigation system on an instrument panel in front of the driver's seat. The display device 14 displays map information, displays the current position of the host vehicle on the map, and displays a predicted route to the destination when the navigation system is operating. The display state of the display device 14 as a navigation system is abbreviated as a navigation image in the following description.

The display device 14 can also display images captured by the side camera 10, the blind spot camera 11, and the rear camera 13. When the slide door switch 5 and the tailgate switch 7 are operated, the navigation image and the cameras 10, 11, Control is performed so that the image captured at 13 is switched.
For example, when an occupant operates the slide door switch 5 to open and close the power slide door 3, an image captured by the side camera 10 and the blind spot camera 11 is displayed on the display device 14. The occupant can confirm the surroundings of the power slide door 3 by viewing the image of the side of the vehicle body displayed on the display device 14, and can open and close the power slide door 3 after confirming the safety of the surroundings. .
When the occupant operates the tailgate switch 7 to open and close the power tailgate 4, an image captured by the rear camera 13 is displayed on the display device 14. The occupant can confirm the surroundings of the power tailgate 4 by viewing the image behind the vehicle body displayed on the display device 14, and can open and close the power tailgate 4 after confirming the safety of the surroundings.

  The image switching of the display device 14 and the operations of the slide door actuator 6 and the tailgate actuator 8 are controlled by the control device 30. For this purpose, output signals from the slide door switch 5 and tailgate switch 7 are input to the control device 30, and image signals from the side camera 10, blind spot camera 11, and rear camera 13 are input to the control device 30.

  The control device 30 controls the image switching of the display device 14 and the operation of the slide door actuator 6 based on the ON signal based on the two operation patterns of the slide door switch 5, and the ON signal based on the two operation patterns for the tailgate switch 7. Based on the above, the image switching of the display device 14 and the operation of the tailgate actuator 8 are controlled.

  The sliding door switch 5 and the tailgate switch 7 in this embodiment are push-type switches having a one-stage contact structure shown in the upper part of FIG. 4 and are configured as switches that are turned on only while the operation unit 21 is being pressed. This switch can be turned on in two patterns depending on the difference in the ON holding time, and the control device 30 determines whether the switch has been turned ON by the first pattern based on the ON holding time or the second pattern. It is determined whether the ON operation has been performed. More specifically, when the switch ON holding time is short (for example, within 0.5 seconds), the control device 30 determines that the ON operation is performed according to the first pattern, and the ON holding time is long. When it is time (for example, 1 second or more), it is determined that the ON operation is performed according to the second pattern.

FIG. 5 is an example of a time chart when the power tailgate 4 is opened. The case of this example will be described.
The occupant turns on the tailgate switch 7 according to the first pattern and then releases the tailgate switch 7 to turn off the tailgate switch 7. At this time, the control device 30 uses the ON signal of the tailgate switch 7 as a trigger, and the video imaged by the rear camera 13 (hereinafter abbreviated as the video image by the rear camera 13) is displayed on the display device 14 for a certain display time (in this example, 3 seconds). ) Only. In this case, when the navigation image is displayed on the display device 14, the navigation image is switched to the video by the rear camera 13.

  In addition, the control device 30 detects the ON holding time of the tailgate switch 7, and determines that the ON operation is performed according to the first pattern when the detected ON holding time is within 0.5 seconds. In the example shown in FIG. 5, since the ON holding time is 100 milliseconds, the control device 30 determines that the tailgate switch 7 has been turned ON in the first pattern.

  While the video from the rear camera 13 is displayed on the display device 14, it is preferable that the occupant confirms the periphery of the power tailgate 4 by viewing the image on the display device 14 and continues to open the power tailgate 4. It is possible to determine whether the situation is present. That is, it is possible to easily and reliably check the surrounding safety before opening the power tailgate 4. When the tailgate switch 7 is turned on again in the first pattern before or after the display time (3 seconds) for displaying the image by the rear camera 13 on the display device 14 has elapsed, the display device 14, the image by the rear camera 13 is displayed again for the display time.

  In the example shown in FIG. 5, when the display of the video by the rear camera 13 is finished on the display device 14 (that is, after 3 seconds), the occupant has finished the safety check around the power tailgate 4, and the power tailgate 4 is determined to be able to continue, and the tailgate switch 7 is turned on by the second pattern.

  The control device 30 detects the ON holding time of the tailgate switch 7, and determines that the ON operation is based on the second pattern when the detected ON holding time is 1 second or longer. In the example shown in FIG. 5, since the ON holding time is close to 2 seconds, the control device 30 determines that the tailgate switch 7 has been turned ON in the second pattern.

  Then, the control device 30 activates the tailgate actuator 8 and starts the opening operation of the power tailgate 4 when a determination time (that is, 1 second) of whether or not the ON operation is performed according to the second pattern has elapsed. At the same time, the hazard lamp of the vehicle blinks and the buzzer sounds. Further, the control device 30 returns the display on the display device 14 from the video by the rear camera 13 to the navigation image after the display time (3 seconds) has elapsed.

  According to the power tailgate 4, the occupant can display the display device between the start of the ON operation according to the first pattern for the tailgate switch 7 and the determination that the ON operation according to the second pattern has been performed. 14, the rear image of the vehicle 1 captured by the rear camera 13 is viewed to check the periphery of the power tailgate 4 and determine whether it is preferable to continue to open the power tailgate 4. can do. That is, it is possible to easily and reliably check the surrounding safety before opening the power tailgate 4.

  When the tail gate switch 7 is controlled to perform the opening operation of the power tailgate 4 on the condition that the ON operation according to the second pattern is performed again after the ON operation according to the first pattern is completed. The safety of the periphery of the power tailgate 4 can be surely urged to the occupant, so safety is further improved.

  However, the control device 30 confirms the ON operation according to the second pattern when the ON operation according to the second pattern is continuously performed while the ON operation according to the first pattern is not completed. It may be controlled to perform the opening operation. In this case, since the video imaged by the rear camera 13 is displayed on the display device 14 while the ON operation according to the second pattern is performed on the tailgate switch 7, the occupant displays on the display device 14 during this time. It is possible to confirm the safety around the power tailgate 4 by looking at the displayed image.

  In addition, since one tailgate switch 7 can display an image of the rear camera 13 on the display device 14 or open the power tailgate 4, the operability is extremely good. Also, the installation space can be smaller than installing separate switches for each function, and the cost can be reduced.

  In the above description, the case where the power tailgate 4 is opened has been described as an example, but the same control can be performed when the power tailgate 4 is closed. In that case, another camera is mounted on the vehicle interior or the inner surface of the power tailgate 4 so that the rear opening of the vehicle, which is a movable region of the power tailgate 4, can be imaged with the power tailgate 4 being flipped up. Or the rear camera 13 is combined with a prism lens so that the rear opening can be imaged. Then, the rear opening image captured by the rear camera 13 or the like when the tailgate switch 7 is turned on is displayed on the display device 14, and the second operation is performed on the tailgate switch 7 after the first pattern is turned on. When the ON operation by the pattern is performed, the power tailgate 4 is closed.

  The same control is performed when the power slide door 3 is opened or closed, and when the slide door switch 5 is turned on, an image captured by the side camera 10 and the blind spot camera 11 is displayed on the display device 14. When the ON operation according to the second pattern is performed on the slide door switch 5 after the ON operation according to the first pattern, the opening operation or the closing operation of the power slide door 3 is performed.

  According to the power slide door 3, the passenger can display the display device between the start of the ON operation according to the first pattern for the slide door switch 5 and the determination that the ON operation according to the second pattern has been performed. 14 shows the side image of the vehicle 1 imaged by the side camera 10 and the blind spot camera 11 displayed on the screen 14, confirms the periphery of the power slide door 3, and continues to open or close the power slide door 3. It can be determined whether or not the situation is favorable. That is, before the power slide door 3 is opened or closed, it is possible to easily and reliably check the surrounding safety.

  In addition, after the ON operation by the 1st pattern is completed with respect to the slide door switch 5, the opening or closing operation | movement of the power slide door 3 is performed on condition that the ON operation by the 2nd pattern was performed anew. If controlled, the occupant can be surely urged to confirm safety around the power slide door 3, thus further improving safety.

  However, the control device 30 confirms the ON operation according to the second pattern when the ON operation according to the second pattern is continuously performed while the ON operation according to the first pattern is not completed. It may be controlled to perform the opening or closing operation. In this case, the image captured by the side camera 10 and the blind spot camera 11 is displayed on the display device 14 while the slide door switch 5 is turned on by the second pattern. The safety displayed around the power slide door 3 can be confirmed by looking at the image displayed on the display device 14.

  The sliding door switch 5 and the tailgate switch 7 may have any contact structure as long as they can be turned on by two patterns. For example, a push-type switch having a contact structure of a two-stage contact shown in the middle stage in FIG. 4 can be used, or a switch having a composite contact structure combining the contact detection and the one-stage contact shown in the lower stage in FIG. It is also possible to configure.

  The push switch with a two-stage contact structure shown in the middle in FIG. 4 is a switch that can detect ON operation by two patterns by different push strokes, and pushes the operation unit 22 with a shallow stroke (for example, 1 mm). In this case, only the first contact (not shown) is turned on, and when the operation unit 22 is pushed in with a deep stroke (for example, 1.5 mm), the first contact and the second contact (not shown) are turned on. It is configured as follows. In other words, this two-stage contact switch distinguishes between the first operation position when the operation unit 22 is pushed in with a shallow stroke and the second operation position advanced by a predetermined stroke from the first operation position. It is configured to be detectable.

When this two-stage contact structure switch is employed, the control device 30 determines that the ON operation has been performed according to the first pattern when the switch detects the first operation position, and the switch When the second operation position is detected, it is determined that the ON operation according to the second pattern has been performed.
In other words, in this two-stage contact structure switch, when the operation unit 22 is pushed in with a shallow stroke, the ON operation is performed by the first pattern, and when the operation unit 22 is pushed in by a deep stroke, the ON operation is performed by the second pattern. Become.

  In addition, the composite contact structure switch shown in the lower part of FIG. 4 has an induced electric field generated when the occupant touches the operation unit 23 with a finger when the operation unit 23 is pushed into the ON state by pressing the operation unit 23 for a predetermined stroke. The touch sensor unit (contact detection unit) 24 that detects a change is configured to be in a first ON state when the occupant simply touches the operation unit 23 with a finger, and the occupant pushes the operation unit 23 by the stroke. And the second ON state. In other words, the switch having the composite contact structure can detect the first operation position when the finger is touched on the operation unit 23 and the second operation position advanced by a predetermined stroke from the first operation position. It is configured.

When the switch having this composite contact structure is adopted, the control device 30 determines that the ON operation according to the first pattern is performed when the switch detects the first operation position, and the switch is When the second operation position is detected, it is determined that the ON operation according to the second pattern has been performed.
In other words, with this composite contact structure switch, when the occupant touches the operation unit 23 with a finger, the ON operation is performed by the first pattern, and when the operation unit 23 is pushed in with a predetermined stroke, the ON operation by the second pattern is performed. Become.

  When these two-point contact structure switches or composite contact structure switches are employed, the operation by the first pattern and the operation by the second pattern for the switch can be clearly distinguished, so that the operability is improved. In addition, since the operation (image display operation) according to the first pattern is always performed before the operation (opening / closing operation) according to the second pattern is performed, the display before the opening / closing operation of the power slide door 3 and the power tailgate 4 is performed. Safety confirmation in the vicinity by the image displayed on the device 14 can be surely promoted, and safety is improved. In addition, it is possible to operate the switch without feeling uncomfortable.

The present invention is not limited to the embodiment described above.
For example, in the above-described embodiment, the opening / closing body is opened / closed by operating a switch provided on the instrument panel. However, the switch may be provided on an inside handle of the opening / closing body. For example, when the inside handle of the opening / closing body is touched or the inside handle is slightly rotated, the image around the opening / closing body imaged by the imaging means is displayed on the display means, and the inside handle is further rotated largely. Thus, the opening / closing body may be opened.
Further, when the door lock switch detects that the door lock is released, an image around the door imaged by the imaging unit may be displayed on the display unit.
