[First Embodiment]
The opening / closing body control method and apparatus according to the first embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing the structure of the opening / closing body control apparatus according to the present embodiment. FIG. 2 is a diagram illustrating an example of an opening / closing body of a vehicle and an operation unit of the opening / closing body by a user.

FIG. 6 is a flowchart showing the opening / closing body control method according to the present embodiment.

  First, the structure of the opening / closing body control apparatus according to the present embodiment will be described with reference to FIGS.

  As shown in FIG. 1, the opening / closing body control device according to the present embodiment includes an operation detection sensor 12, a contact detection sensor 14, an opening / closing body drive device 16, a holding force adjustment device 18, and a control device 20. ing. The control device 20 is connected to the operation detection sensor 12 and the contact detection sensor 14, and can receive output signals from the operation detection sensor 12 and the contact detection sensor 14. The control device 20 is also connected to the opening / closing body driving device 16 and the holding force adjusting device 18, and can output control signals for driving them to the opening / closing body driving device 16 and the holding force adjusting device 18. ing.

  Next, each part of the opening / closing body control apparatus according to the present embodiment will be described in detail.

  The opening / closing body 10 is a structure having an opening / closing mechanism provided in the vehicle. The opening / closing body 10 is not particularly limited. For example, in a vehicle 30 as shown in FIG. 2, a side door 32 provided on a side portion of the vehicle 30 and a back door 34 provided on a rear portion of the vehicle 30. And so on. The opening / closing body 10 is not limited to a swing door such as the side door 32 shown in FIG. 2, and may be a sliding door.

  The operation detection sensor 12 is a sensor for detecting a user's intention to open the opening / closing body 10 of the vehicle (hereinafter referred to as “open operation intention”) based on the user's operation. The user's intention to open is confirmed based on, for example, that a part of the user's body has entered the operation detection area near the operation unit of the opening / closing body 10 or that the user has taken a specific pose or action. be able to.

  Here, in this specification, the “operation part” of the opening / closing body 10 refers to a portion of the opening / closing body 10 that contacts when the user opens the opening / closing body 10 to a desired opening degree. As an example, the operation unit of the opening / closing body 10 will be described by taking as an example a case where the user gets on the vehicle 30 shown in FIG.

  First, the user pulls the side door 32 with the door handle 36, and when the door is opened to some extent, the user moves toward the gap of the side door 32 that is slightly opened as a preparation operation for boarding. When the user moves toward the gap of the side door 32, it becomes difficult to open the side door 32 to a desired opening degree necessary for boarding while holding the outside handle portion 36. Therefore, the user picks up a part of the opening / closing body 10 that is easier to hold from the outside handle portion 36 and opens the side door 32 to a desired opening, and then gets into the vehicle. When such a series of door opening operations is assumed, the operation part of the opening / closing body 10 corresponds to the part of the opening / closing body 10 that is re-held from the outside handle part 36 and easier to hold when opening and closing. For example, in the case of the vehicle 30 illustrated in FIG. 2, as the operation unit, the pillar portion 38 of the side door 32, the door panel portion 40, and the lower end portion 42 of the back door 34 are assumed.

  In addition, the “operation detection area” is an area where a specific pose or motion performed when the user indicates an opening operation intention can be detected, and corresponds to the detection area of the operation detection sensor 12. The operation detection area is preferably provided in the vicinity of the operation unit of the opening / closing body 10. In particular, it is more desirable that the operation detection area is provided so that the operation portion when the opening / closing body 10 is in the pop-up opening position is located within the operation detection area when the opening / closing body 10 is in the closed position. Although details will be described later, the opening operation of the opening / closing body 10 thereafter can be smoothly performed by providing the operation detection area in this manner. For example, in the vehicle 30 shown in FIG. 3, when the pillar portion 38 of the side door 32 is assumed to be an operation portion, the operation detection area 44 is a space within a certain range surrounding the pillar portion 38 as indicated by a dotted line in FIG. 3. Can be set to

  If the operation detection area is too wide, erroneous detection increases. If the operation detection area is too narrow, the operability deteriorates. Therefore, it is desirable to appropriately select an appropriate range in consideration of both sides of prevention of false detection and improvement of operability.

  When determining the intention of opening operation based on a part of the user's body, the user has the intention of opening operation in order to prevent the user from malfunctioning when the vehicle simply passes by the side of the vehicle without intention of opening operation. It is desirable to detect that a specific part of the body that can be determined as having entered the operation detection area. The specific part of the body is not particularly limited, but from the viewpoint of smoothly performing the subsequent door opening operation, for example, a user's hand or elbow can be preferably exemplified.

  In addition, when the user's pose or action is used to determine the intention to open, the user's pose or action is not particularly limited. However, from the standpoint of smoothly opening the door, the user can detect the operation. An operation such as holding a hand over the area or raising the elbow toward the operation detection area by the user can be suitably exemplified.

  Part of the user's body and movement can be identified by using an existing technique that three-dimensionally measures the user's skeleton using, for example, a camera, an infrared sensor, an ultrasonic sensor, or a combination thereof. . As an example of an existing device that generates output information for specifying a part of a user's body or a pose, a distance image sensor, a depth of field sensor, or the like can be given. Although such a sensor is not specifically limited, For example, it can mount in the side mirror 46 part.

  The operation detection sensor 12 does not necessarily specify a part of the user's body or an action, and measures the distance between a part of the user's body and the operation unit, and the distance between the user's body and the operation unit. It may be determined that the intention of opening operation is that the value of is below a certain value. Examples of the operation detection sensor 12 capable of measuring the distance between a part of the user's body and the operation unit include an infrared sensor. The operation detection sensor 12 using an infrared sensor can be installed, for example, in the operation unit of the opening / closing body 10.

  Further, from the viewpoint of reducing erroneous detection of the opening operation intention by the operation detection sensor 12, the opening operation intention is recognized when the detection state determined to indicate the opening operation intention has been maintained for a certain period of time. May be.

  Further, from the viewpoint of notifying the user whether or not the user's intention to open the operation is normally detected by the operation detection sensor 12, while the operation detection sensor 12 recognizes the operation to the operation unit by the user, You may make it alert | report to that.

  The contact detection sensor 14 is a sensor for detecting that the user is in contact with the operation unit of the opening / closing body 10. An example of a sensor that can detect contact of the user with the operation unit is a capacitance sensor. Advantages of the capacitance sensor include, for example, that the designability is not deteriorated, and that the contact state can be reliably detected even with light contact compared to a switch or the like.

  The arrangement place of the contact detection sensor 14 is an operation unit of the opening / closing body 10. For example, in the case of the vehicle 30 shown in FIG. 2, the location of the contact detection sensor 14 is assumed to be the pillar portion 38 of the side door 32, the door panel portion 40, and the lower end portion 42 of the back door 34.

  The contact detection sensor 14 may also be provided inside the opening / closing body 10. For example, when the user grasps the pillar portion 38 or the door panel portion 40 of the side door 32, the user's hand also contacts the inside of the side door 32. Alternatively, when the user inserts an elbow into the gap between the side doors 32 opened by the pop-up opening operation and further opens the elbow, the user's elbow contacts the inside of the side door 32. Therefore, the contact of the user with the opening / closing body 10 can be detected by a contact detection sensor provided inside the opening / closing body 10.

  In the pop-up opening operation, a user can insert a finger into the open gap of the opening / closing body 10 to grasp the opening / closing body 10, or the user inserts an elbow into the opening gap of the opening / closing body 10 to open the opening / closing body 10. It is sufficient if the opening degree can be secured. This is because if the opening degree of the opening / closing body 10 by the pop-up opening operation is too large, it may cause an unexpected accident such as collision with another vehicle parked adjacently when the opening / closing body 10 is opened. . It is desirable that the opening degree of the opening / closing body 10 opened by the pop-up opening operation be as small as possible within a range in which the user can insert a finger or an elbow into the open gap of the opening / closing body 10.

  In the case where the distance between a part of the user's body and the operation unit is measured by the operation detection sensor 12, the opening / closing body 10 may be popped up to match the measured distance. In this case, a sensor for measuring a distance between a part of the user's body and the operation unit may be separately provided.

  An example of the opening / closing body driving device 16 will be described with reference to FIG. 4 includes a door opening / closing motor 50, a rotation transmission clutch 52, a rotation-reciprocation conversion mechanism 54, and a telescopic rod 56. In the opening / closing body driving device 16, the rotational movement of the door opening / closing motor 50 is transmitted to the rotation / reciprocation conversion mechanism 54 via the rotation transmission clutch 52, and converted into the reciprocation movement of the telescopic rod 56. By this operation, the telescopic rod 56 can be expanded and contracted by a length corresponding to the rotation of the door opening / closing motor 50. At this time, by fixing one end of the telescopic rod 56 to the vehicle 30 main body, the opening / closing body 10 can be opened at a predetermined opening according to the rotation of the door opening / closing motor 50. That is, in a state where the door opening / closing motor 50 and the rotation-reciprocation conversion mechanism 54 are connected by the rotation transmission clutch 52, the door opening / closing motor 50 is rotated by a predetermined amount by the control device 20, thereby achieving a desired opening degree. The opening / closing body 10 can be popped up.

  The opening / closing body driving device 16 is not limited to the one shown in FIG. 4 as long as the opening / closing body 10 can perform the pop-up opening operation.

  The holding force adjusting device 18 is for adjusting the holding force of the opening / closing body 10. Here, the holding force of the opening / closing body 10 is a force for fixing the opening / closing body 10 at a certain position. The smaller the holding force, the easier the opening / closing body 10 moves, and the larger the holding force, the less difficult the opening / closing body 10 moves. Become.

  The holding force adjusting device 18 can form at least two holding states of “free state” and “brake state”. Here, the “free state” is a state in which the holding force of the opening / closing body 10 is small. For example, the opening / closing body 10 can be freely operated with a light operating force of a necessary operating force in a flat portion of a normal door check. State. The “brake state” is a state where the holding force of the opening / closing body 10 is large, for example, a state where the opening / closing body 10 is restrained by a holding force equivalent to the holding force of a normal door check. The expressions “free state” and “brake state” are for convenience of understanding, and the holding force of the opening / closing body 10 in the “free state” and “brake state” is necessary and convenient. It can be appropriately changed in consideration of the above. In this specification, the holding force in the free state may be expressed as a first holding force, and the holding force in the brake state may be expressed as a second holding force.

  An example of the holding force adjusting device 18 will be described with reference to FIG. The holding force adjusting device 18 shown in FIG. 5 includes a cylinder 62 arranged so as to sandwich the check arm 60 from above and below, a piston 66 slidably provided in the cylinder 62 via a packing 64, And a friction member 68 provided at the end on the check arm 60 side.

  One end of the check arm 60 is fixed to the vehicle 30 main body so as to be freely rotatable. Along with the opening / closing operation of the opening / closing body 10, a space between the upper and lower cylinders 62 installed in the opening / closing body 10 is illustrated. It is designed to reciprocate in the left-right direction. When gas is introduced from a gas inlet 70 provided in the cylinder 62 by an air compressor (not shown), the piston 66 moves in the direction of the check arm 60 due to the pressure of the gas, and is checked by a friction member 68 provided at the tip of the piston 66. The arm 60 is clamped. By appropriately adjusting the pressure of the gas introduced into the cylinder 62, the check arm 60, that is, the opening / closing body 10 can be restrained with a desired holding force. Further, by venting the gas in the cylinder 62, the restraint of the check arm 60 by the friction member 68 can be released, and the holding force of the check arm 60, that is, the opening / closing body 10 can be reduced.

  The holding force adjusting device 18 is not limited to that shown in FIG. 5 as long as the holding force of the opening / closing body 10 can be adjusted.

  In response to the output signals from the operation detection sensor 12 and the contact detection sensor 14, the control device 20 outputs a control signal for driving the opening / closing body driving device 16 and the holding force adjusting device 18, and pops up the opening / closing body 10. This is for controlling the operation and the holding force of the opening / closing body 10.

  The control device 20 includes an operation detection signal receiving unit (first signal receiving unit) that receives an output signal (first detection signal) from the operation detection sensor 12, and an output signal (second output) from the contact detection sensor 14. Contact detection signal receiving means (second signal receiving means) for receiving a detection signal). Further, a drive control signal output means (first signal output means) for outputting a drive control signal (first control signal) for a pop-up opening operation to the opening / closing body driving device 16, and an opening / closing body to the holding force adjusting device 18. Holding force control signal output means (second signal output means) for outputting a holding force control signal (second control signal) for adjusting the holding force of 10. Moreover, it has a position detection signal receiving means for receiving a position detection signal from a position detection sensor (not shown) that detects the position of the opening / closing body 10 (for example, whether the opening / closing body 10 is fully closed).

  In the present specification, not only the entire system but also only the control device 20 may be referred to as an “opening / closing body control device”.

  Next, the opening / closing body control method according to the present embodiment will be described with reference to FIGS.

  The pop-up opening operation and holding force adjustment of the opening / closing body 10 are controlled by the control device 20 as follows, for example, according to the flowchart shown in FIG. Note that the flowchart for realizing the opening / closing body control method according to the present embodiment is not limited to that shown in FIG. 6, and appropriate modifications and changes can be made within the scope in which the present embodiment can achieve the intended effect. Is possible.

  First, the control device 20 receives a position detection signal from a position detection sensor (not shown), and determines whether or not the opening / closing body 10 is in a fully closed state (step S101). When the opening / closing body 10 is in the fully closed state, the process proceeds to step S102. When the opening / closing body 10 is not in the fully closed state, that is, when the opening / closing body 10 is open, the pop-up opening operation is unnecessary, and the process proceeds to step S104.

  In step S <b> 102, the control device 20 receives an output signal from the operation detection sensor 12. When the output signal indicating the intention to open the opening / closing body 10 by the user (operation to the operation unit) is received from the operation detection sensor 12, the process proceeds to step S103. When the operation detection sensor 12 does not receive an output signal indicating the operation of the opening / closing body 10 by the user to the operation unit, the operation of step S102 is repeated and the standby state is maintained.

  In step S <b> 103, the control device 20 outputs a pop-up control signal to the opening / closing body driving device 16 to cause the opening / closing body 10 to perform a pop-up opening operation. After the pop-up opening operation, the process proceeds to step S104.

  In step S <b> 104, the control device 20 receives an output signal from the contact detection sensor 14. When the control device 20 receives from the contact detection sensor 14 an output signal indicating that the user has touched the operating portion of the opening / closing body 10, the control device 20 proceeds to step S105 and sets the holding force of the opening / closing body 10 to a free state. . Since the contact of the user with the opening / closing body 10 after the pop-up opening operation is determined to open the opening / closing body 10 from the pop-up position to an arbitrary opening degree, the holding force of the opening / closing body 10 is set to a free state. This is because the user can operate the opening / closing body 10 smoothly without stress.

  On the other hand, when the control device 20 does not receive an output signal indicating that the user has touched the operating portion of the opening / closing body 10 from the contact detection sensor 14, the process proceeds to step S106, and the holding force of the opening / closing body 10 is braked. And If the user does not hold the opening / closing body 10 in a state where the opening / closing body 10 is open, the opening / closing body 10 moves due to its own weight or wind, and the opening / closing body 10 collides with the adjacent parked vehicle, This is because an unexpected accident such as a finger being pinched in 10 may occur.

  After step S105 or step S106, the process returns to step S101 and the same steps are repeated. In this way, when the user is in contact with the operation unit of the opening / closing body 10 in a state in which the opening / closing body 10 after the pop-up opening operation is opened, the holding force of the opening / closing body 10 is maintained in a free state, The opening / closing body 10 can be operated smoothly without stress. Further, when the user is not in contact with the operation part of the opening / closing body 10, the holding force of the opening / closing body 10 is set to a brake state, and movement (self-running) of the opening / closing body 10 not based on the user's intention can be suppressed.

  When the user performs the above-described series of operations, the detection area of the operation detection sensor 12 that detects the user's intention to open the operation, that is, the operation detection area 44, as described above, is located at or near the operation portion of the opening / closing body 10. It is desirable to provide it. In particular, the operation detection area 44 may be further provided so that the operation portion when the opening / closing body 10 is in the pop-up opening position is located within the operation detection area 44 when the opening / closing body 10 is in the closed position. desirable. For example, the operation part of the opening / closing body 10 is installed in the pillar part 38 of the side door 32, and the operation detection area 44 is set in a space of a certain distance from the operation part. When the opening / closing body 10 is opened by about 15 cm by the pop-up opening operation, a space having a distance of about 15 cm from the operation unit in the closed position is set as the operation detection area. By setting the operation detection area 44 in such a range, the operation of the opening / closing body 10 after the pop-up opening operation can be performed more smoothly.

  For example, when the user holds his / her hand over the operation detection area 44 and indicates the opening action intention, when the opening / closing body 10 pops up, the opening / closing body 10 opened in the hand held by the user for displaying the opening action intention is displayed. The operation unit automatically enters. The user can smoothly shift to the opening operation by holding the operation part of the opening / closing body 10 that has entered the hand as it is. When the user grips the operating portion of the opening / closing body 10, the holding force of the opening / closing body 10 is in a free state, so that the user can open the opening / closing body 10 smoothly to a desired opening without stress. When opening the opening / closing body 10 to a desired opening, it is not necessary to re-open the opening / closing body 10. After the user releases the opening / closing body 10, the holding force of the opening / closing body 10 is in a braking state, so that the opening / closing body 10 can be prevented from traveling on its own.

  As described above, according to the present embodiment, when the user operates the operation unit of the opening / closing body 10, the opening / closing body 10 performs a pop-up opening operation, and when the user contacts the operation unit, the holding force of the opening / closing body 10 is increased. Since it becomes a free state, a series of door opening operation | movement which opens the opening / closing body 10 from a fully closed state to a desired opening degree can be performed smoothly, without a user holding the opening / closing body 10 again. Further, when the user releases the contact from the opening / closing body 10, the holding force is in a braking state, so that the opening / closing body 10 self-propels and the opening / closing body 10 collides with a vehicle parked next to the opening / closing body 10. You can prevent unexpected accidents such as pinching your hands or feet.

[Second Embodiment]
The opening / closing body control method and apparatus according to the second embodiment of the present invention will be described with reference to FIGS. Constituent elements similar to those of the opening / closing body control method and apparatus according to the first embodiment shown in FIG. 1 to FIG.

  FIG. 7 is a block diagram showing the structure of the opening / closing body control apparatus according to the present embodiment. FIG. 8 is a flowchart showing a control method of the opening / closing body in the opening / closing body control apparatus according to the present embodiment.

  First, the structure of the opening / closing body control apparatus according to the present embodiment will be described with reference to FIG.

  As shown in FIG. 7, the opening / closing body control device according to the present embodiment includes an operation detection sensor 12, an opening / closing body driving device 16, a holding force adjusting device 18, and a control device 20.

  In the first embodiment, an example in which a non-contact type sensor is applied to the operation detection sensor 12 has been described. However, the operation detection sensor 12 is not necessarily a non-contact type sensor. The operation detection sensor 12 may be a contact type sensor that determines that the user's contact is an intention to open.

  As described in the first embodiment, it is desirable that the operation detection area of the operation detection sensor 12 is provided in the operation portion of the opening / closing body 10 or in the vicinity thereof. The same applies to the case where the operation detection sensor 12 is configured by a contact type sensor. In this case, it is desirable to provide the operation detection sensor 12 in the operation unit.

  When the contact-type operation detection sensor 12 is provided in the operation unit, as in the opening / closing body control device according to the present embodiment, a single sensor (operation detection sensor 12 of the present embodiment) provided in the operation unit is used in the first embodiment. The operation detection sensor 12 and the contact detection sensor 14 can be combined. In this case, the “operation detection area” is the same as the “operation unit”.

  In the opening / closing body control device according to the present embodiment, the operation detection sensor 12 can be configured by a simple and inexpensive sensor such as a capacitance sensor, and the number of parts is reduced as compared with the opening / closing body control device according to the first embodiment. Therefore, a cheaper system can be realized.

  Next, the opening / closing body control method according to the present embodiment will be described with reference to FIGS.

  The pop-up opening operation and holding force adjustment of the opening / closing body 10 are controlled by the control device 20 as follows, for example, according to the flowchart shown in FIG. Note that the flowchart for realizing the opening / closing body control method according to the present embodiment is not limited to that shown in FIG. 8, and appropriate modifications and changes can be made within a range in which the effect of the present embodiment can be achieved. Is possible.

  First, the control device 20 receives a position detection signal from a position detection sensor (not shown), and determines whether or not the opening / closing body 10 is in a fully closed state (step S201). When the opening / closing body 10 is fully closed, the process proceeds to step S202. When the opening / closing body 10 is not in the fully closed state, that is, when the opening / closing body 10 is open, the pop-up opening operation is unnecessary, and the process proceeds to step S204.

  In step S <b> 202, the control device 20 receives an output signal from the operation detection sensor 12. When the output signal which shows the opening operation intention (contact to an operation part) of the opening / closing body 10 by a user is received from the operation detection sensor 12, it transfers to step S203. When the output signal which shows the contact to the operation part of the opening / closing body 10 by a user is not received from the operation detection sensor 12, the operation | movement of step S202 is repeated and a standby state is maintained.

  In step S <b> 203, the control device 20 outputs a pop-up control signal to the opening / closing body driving device 16 to cause the opening / closing body 10 to perform a pop-up opening operation. After the pop-up opening operation, the process proceeds to step S204.

  In step S <b> 204, the control device 20 receives an output signal from the operation detection sensor 12. When the control device 20 receives from the operation detection sensor 12 an output signal indicating that the user has touched the operating portion of the opening / closing body 10, the control device 20 proceeds to step S205 and sets the holding force of the opening / closing body 10 to a free state. .

  On the other hand, when the control device 20 does not receive from the operation detection sensor 12 an output signal indicating that the user has touched the operating portion of the opening / closing body 10, the process proceeds to step S206, and the holding force of the opening / closing body 10 is set to the brake state. And

  After step S205 or step S206, the process returns to step S201 and the same steps are repeated. In this way, when the user is in contact with the operation unit of the opening / closing body 10 in a state in which the opening / closing body 10 after the pop-up opening operation is opened, the holding force of the opening / closing body 10 is maintained in a free state, The opening / closing body 10 can be operated smoothly without stress. Further, when the user is not in contact with the operation part of the opening / closing body 10, the holding force of the opening / closing body 10 is set to a brake state, and movement (self-running) of the opening / closing body 10 not based on the user's intention can be suppressed.

  As described above, according to the present embodiment, when the user operates the operation unit of the opening / closing body 10, the opening / closing body 10 performs a pop-up opening operation, and when the user contacts the operation unit, the holding force of the opening / closing body 10 is increased. Since it becomes a free state, a series of door opening operation | movement which opens the opening / closing body 10 from a fully closed state to a desired opening degree can be performed smoothly, without a user holding the opening / closing body 10 again. Further, when the user releases the contact from the opening / closing body 10, the holding force is in a braking state, so that the opening / closing body 10 self-propels and the opening / closing body 10 collides with a vehicle parked next to the opening / closing body 10. You can prevent unexpected accidents such as pinching your hands or feet.

  Moreover, since the sensor for detecting the state of the opening / closing body 10 is configured by one contact detection sensor, the number of parts and the part cost can be reduced, and a more inexpensive system can be realized.

[Modified Embodiment]
The present invention is not limited to the above embodiment, and various modifications can be made.

For example, in the above-described embodiment, two types of holding states of “free state” and “brake state” are defined, and the method of controlling the holding force of the opening / closing body 10 to these two states has been described. There are not necessarily two types of holding states. A plurality of types of holding states may be defined, and control may be performed so as to appropriately switch to the plurality of holding states according to the operating state of the opening / closing body 10.
Further, in the second embodiment, the functions of the operation detection sensor 12 and the contact detection sensor 14 are shared by one contact type sensor, but one contact is made for each of the operation detection sensor 12 and the contact detection sensor 14. A type sensor may be provided. For example, a sensor for the operation detection sensor 12 may be provided outside the pillar portion 38, and a sensor for the contact detection sensor 14 may be provided inside the pillar portion 38.
