  Opening / closing bodies that can close and open the openings provided in the vehicle body, such as vehicle back doors, sliding doors, windows, etc., have recently been opened / closed by opening and closing the opening / closing bodies electrically (motor driving force). In addition, with the introduction of the keyless entry system described above, a plurality of means (for example, the vicinity of the position where the opening / closing body is installed, the driver's seat, etc.) can be opened / closed by the opening / closing mechanism. A plurality of opening / closing instruction switches provided at different locations or a portable transmitter of a keyless entry system) can be instructed. However, along with this, when different users give instructions to move the same opening / closing body to the same position at approximately the same time, the opening / closing body may move to a position contrary to the user's intention. There was a problem.

  For example, for opening and closing the back door of a vehicle, an open / close instruction switch is provided in the vicinity of the position where the back door is disposed, the driver's seat and the portable transmitter of the keyless entry system, and the open / close instruction switch is operated to open / close the back door There are known systems that can also indicate In this type of system, in order to avoid complicated operations due to the provision of a large number of switches and an increase in the size of the portable transmitter, a configuration in which each switch is provided as a single open / close instruction switch is often employed. The opening / closing mechanism opens / closes the back door by selecting the opening / closing direction according to the current state (position and moving direction) of the opening / closing body each time the opening / closing instruction switch is turned on by the user and the opening / closing instruction is input. .

  Here, for example, when a certain user operates the open / close instruction switch near the position where the back door is disposed and moves it to the open side with respect to the back door that is in the fully closed state, the back door is moved. When a driver's seat that is difficult to check or another user outside the vehicle operates the driver's seat or the open / close instruction switch of the portable transmitter without noticing the movement of the back door and trying to move the back door to the open side In the opening / closing mechanism to which an opening / closing instruction is input in accordance with this operation, the direction of movement of the back door is reversed based on the fact that the back door has already moved to the open side, and the driver's seat or the portable transmitter The back door is moved to a closed position contrary to the intention of the user who operated the open / close instruction switch. And when the opening degree of the back door when the moving direction of the back door is reversed is small, a small foreign object that is difficult for the user who operates the opening / closing instruction switch of the driver's seat or the portable transmitter to check, There is also the possibility of being caught between the back door and the body.

  The present invention has been made in consideration of the above facts, and it can be used for a vehicle that can prevent the opening / closing body from being moved to a position contrary to the instructor's intention in response to the opening / closing instruction input via the remote control device. It is an object to obtain an opening / closing drive device for an opening / closing body.

  In order to achieve the above object, an opening / closing drive device for a vehicle opening / closing body according to claim 1 is provided between an open position for opening an opening provided in a vehicle body of a vehicle and a closed position for closing the opening. And a driving means for moving the opening / closing body disposed in the vehicle to open or close in accordance with an opening / closing instruction input via a remote control device, and detecting an opening of the opening / closing body. When the opening detected by the opening detecting means when the opening / closing instruction is input to the driving means via the remote operation device and the opening detecting means is below a predetermined value, the driving means And prohibiting means for prohibiting the opening / closing body from moving to the closing side in accordance with an opening / closing instruction.

  A vehicle in which the opening / closing drive device for a vehicle opening / closing body according to the first aspect of the present invention is mounted is provided between an open position for opening an opening provided in a vehicle body of the vehicle and a closed position for closing the opening. An openable / closable body that is movable is disposed, and the drive unit moves the open side or the close side according to an open / close instruction input via the remote control device. As the opening / closing body according to the present invention, for example, any one of a vehicle back door, a slide door, a swing door, a window, and a luggage compartment door can be applied. It may be another opening / closing body such as. The remote control device is a transmitter that is provided with an open / close instruction switch for instructing opening / closing of the open / close body, and outputs an open / close instruction wirelessly (electromagnetic waves, infrared rays, etc.) according to the operation of the open / close instruction switch. There may be an opening / closing instruction switch that outputs an opening / closing instruction by being provided and operated at a position away from the position where the opening / closing body is disposed in the vehicle interior (for example, a driver's seat if the opening / closing body is a back door). It may be.

  The invention described in claim 1 is provided with opening degree detecting means for detecting the opening degree of the opening / closing body, and the prohibiting means detects the opening degree when an opening / closing instruction is inputted to the driving means via the remote control device. When the opening detected by the means is less than or equal to a predetermined value, the drive means is prohibited from moving the opening / closing body to the closing side in accordance with the opening / closing instruction. Thus, in the first aspect of the present invention, when an opening / closing instruction is input via the remote control device by an instructor who desires to move the opening / closing body to the open position, at least the opening / closing body at that time Since the opening / closing body is prevented from being moved to a closed position contrary to the intention of the instructor, the instructor can respond to the opening / closing instruction input via the remote control device. It is possible to suppress the opening / closing body from being moved to a position contrary to the intention. In addition, this makes it possible to prevent a small-size foreign object that is difficult to check from being sandwiched between the opening / closing body and the vehicle body.

  In the invention described in claim 1, when the opening / closing operation device for opening / closing the opening / closing body by the driving means is provided in the vicinity of the position where the opening / closing body is disposed, the prohibiting means is, for example, as described in claim 2 In addition, when an opening / closing instruction is input to the driving means via the remote operation device, the driving means moves the opening / closing body to the open side according to the instruction input via the opening / closing operation device, and the opening degree detection means It is preferable that the drive means is prohibited from moving the opening / closing body to the closed side in accordance with the opening / closing instruction only when the opening detected by the above is less than or equal to a predetermined value.

  Thus, when the opening / closing instruction is input to the driving means via the remote operation device while the driving means is moving the opening / closing body to the open side according to the instruction input via the opening / closing operation device, If the opening degree of the opening / closing body is equal to or less than a predetermined value, the driving means is prohibited from moving the opening / closing body to the closed side in accordance with an instruction input via the remote operation device, while driving via the opening / closing operation device. If no instruction is input to the means and the opening / closing body has not been moved to the open side, the driving means is input via the remote control device regardless of whether the opening / closing body is below a predetermined value. Since it is not prohibited to move the opening / closing body to the closing side according to the opening / closing instruction, it is not unnecessarily restricted that the driving means moves the opening / closing body according to the opening / closing instruction input via the remote control device, Via remote control Usability when opening and closing the closing member is improved.

Further, in the invention described in claim 1, the prohibiting means is, for example, as described in claim 3,

  In the invention according to any one of claims 1 to 3, a single switch for instructing the remote control device to open and close the opening / closing member is provided, and the remote control device is turned on. When the opening / closing instruction is output every time, the driving means receives the opening / closing instruction when the opening / closing body is in the open position or moved to the open side, for example, as described in claim 4. If the open / close instruction is input when the open / close body is in the closed position or is moving to the close side, the open / close body is moved to the open side. You may comprise.

  As described above, the present invention provides a remote control device for an opening / closing body disposed in a vehicle so as to be movable between an open position for opening an opening provided in a vehicle body of a vehicle and a closed position for closing an opening. Remote operation when the opening degree of the opening / closing body when the opening / closing instruction is input via the remote control device is less than or equal to a predetermined value when moving to the opening side or the closing side according to the opening / closing instruction input via Since the opening / closing body is prohibited from moving to the closing side in accordance with the instruction input via the device, the opening / closing body is moved to a position contrary to the instructor's intention with respect to the opening / closing instruction input via the remote operation device. It has the outstanding effect that it can suppress that is moved.

  Hereinafter, an example of an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows an electric back door system 10 according to the present embodiment. The electric back door system 10 is a system that is mounted on a vehicle and that opens and closes a back door 12 (see FIG. 2 and the like) supported by the rear end of the vehicle so as to be opened and closed by a driving force of a drive motor. A back door control unit 14 including a peripheral circuit is provided. The back door 12 corresponds to the opening / closing body according to the present invention, and the electric back door system 10 corresponds to the opening / closing drive device for the vehicle opening / closing body according to the present invention.

  A drive motor 16 that generates a driving force for opening and closing the back door 12 is connected to the back door control unit 14 via a motor drive circuit 18, and the back door control unit 14 is connected to the drive motor via the motor drive circuit 18. 16 drive is controlled. As shown in FIG. 2, the drive motor 16 is built in a back door drive unit 20 attached in the vicinity of the position where the back door 12 is disposed, and one end of the drive motor 20 is connected to the back door via a rod 24. The other end of the drive arm 22 connected to the door 12 is pivotally supported so as to be rotatable in the direction of arrow A in FIG. 2 or the direction of arrow B in FIG. The back door drive unit 20 incorporates a gear mechanism (not shown) interposed between the rotation shaft of the drive motor 16 and the rotation shaft of the drive arm 22, and the drive force of the drive motor 16 passes through the gear mechanism. When the drive arm 22 is rotated in the direction of arrow A in FIG. 2, the back door 12 is rotated in the opening direction, and the drive arm 22 is rotated in the direction of arrow B in FIG. Then, the back door 12 is rotated in the closing direction. The back door drive unit 20 including the drive motor 16, the drive arm 22 and the rod 24, and the motor drive circuit 18 correspond to the drive means according to the present invention together with the back door control unit 14 that controls the drive of the drive motor 16. ing.

  As shown in FIG. 3, the back door drive unit 20 includes a spacer 26, a magnet clutch 28, and a door sensor 30 in addition to the gear mechanism described above. The magnet clutch 28 is interposed between the rotation shaft of the drive motor 16 and the gear mechanism, and can transmit / shut off the drive force of the drive motor 16 to the gear mechanism. The magnet clutch 28 is connected to the back door control unit 14 (see FIG. 1), and the back door control unit 14 controls switching between the driving force transmission state and the cutoff state. When the back door control unit 14 normally opens and closes the back door 12 with the driving force of the drive motor 16 when the magnet clutch 28 is maintained in the driving force cutoff state so that the back door 12 can be manually opened and closed. Controls the switching of the state of the magnet clutch 28 so that the magnet clutch 28 is switched to the driving force transmission state.

  In addition, a large number of magnets are attached to the outer peripheral portion of the magnet clutch 28 (the portion that rotates when the driving force is transmitted in the driving force transmission state) at a constant pitch, and the door sensor 30 is separated from the above by a gap. It is comprised by two Hall IC each arrange | positioned so as to oppose the magnet. The two Hall ICs are sequentially arranged along the circumferential direction of the outer periphery of the magnet clutch 28, and each output a pulse signal corresponding to the movement of the magnet, that is, the rotation of the outer periphery of the magnet clutch 28. The door sensor 30 is connected to the back door control unit 14 (see FIG. 1), and pulse signals output from the two Hall ICs are input to the back door control unit 14, respectively.

  The back door control unit 14 is input from the door sensor 30 (two Hall ICs) when the magnet clutch 28 is switched to the driving force transmission state and the driving motor 16 is driven to open and close the back door 12. Based on the pulse signal, an overload applied to the drive motor 16 is detected, the current position of the back door 12 is detected, and the movement direction of the back door 12 is detected. That is, since the back door control unit 14 controls the drive of the drive motor 16 so that the rotation shaft of the drive motor 16 rotates at a predetermined speed, as shown in FIG. The period of the pulse signal input from the two Hall ICs is constant (T ′) when no load is applied), but when the drive motor 16 is overloaded, the rotational speed of the rotating shaft decreases. The period of the pulse signal is longer than the stationary period T (T (> T ′)). For this reason, the back door control unit 14 monitors a change in the period of the input pulse signal and detects an overload applied to the drive motor 16 based on the change in the period of the pulse signal.

  Since the magnet detected by the Hall IC is attached to the outer periphery of the magnet clutch 28 at a constant pitch, the number of pulses of the pulse signal input from the Hall IC is the amount of rotation of the rotating shaft of the drive motor 16, that is, the back This corresponds to the position (opening degree) of the door 12. For this reason, as shown in FIG. 4B, the back door control unit 14 detects the current position (opening degree) of the back door 12 by counting the number of pulses of the input pulse signal. Thus, the door sensor 30 (two Hall ICs thereof) and the back door control unit 14 correspond to the opening degree detection means according to the present invention.

  Further, since the two Hall ICs are arranged in order along the circumferential direction of the outer periphery of the magnet clutch 28, as shown in FIG. 4C, the rotation direction of the outer periphery of the magnet clutch 28, that is, the back Depending on the moving direction of the door, the level change relationship of the pulse signals input from the two Hall ICs is switched. In FIG. 4C, when the back door 12 moves in the opening direction, the pulse signal of the other Hall IC (Hall IC2) becomes low level when the pulse signal of one Hall IC (Hall IC1) rises. In this example, when the back door 12 moves in the closing direction, the pulse signal of the Hall IC 2 is at the high level when the pulse signal of the Hall IC 1 rises. For this reason, the back door control part 14 detects the present moving direction of the back door 12 based on the relationship of the level change of the pulse signal each input from two Hall IC.

  Further, as shown in FIG. 5, the instrument panel of the vehicle on which the electric back door system 10 is mounted has a main switch 32 of the electric back door system 10 and an opening / closing instruction for instructing opening / closing of the back door 12. A switch 34 is provided. The main switch 32 and the opening / closing instruction switch 34 are connected to the back door control unit 14 (see FIG. 1), and the back door control unit 14 opens / closes the instruction switch 34 (or will be described later) only when the main switch 32 is turned on. The drive motor 16 is driven in response to an on / off operation of an open / close instruction switch 44, a back door opener switch 50, a back door close switch 52, and the like. The portion of the instrument panel of the vehicle where the main switch 32 and the opening / closing instruction switch 34 are provided corresponds to the remote control device according to claim 1 (specifically claim 4).

  Further, a vehicle equipped with the electric back door system 10 is also equipped with a keyless entry system. As shown in FIG. 6, an ignition key 36 (hereinafter referred to as a transmitter 36) of the vehicle that functions as a transmitter is A flat rectangular grip portion 38 made of a synthetic resin and rounded at corners, and a key plate 40 having one end portion embedded in the grip portion 38 and engraved with a groove 40A that functions as an ignition key, In addition to a plurality of switches 42 for operating the keyless entry system, an opening / closing instruction switch 44 for instructing opening / closing of the back door is also provided on the side of the grip portion 38. When the switch 42 or the opening / closing instruction switch 44 is turned on in the grip portion 38 of the transmitter 36, the high frequency signal modulated according to the information corresponding to the turned on switch is supplied to the key plate 40 to turn on. An electronic circuit (not shown) for transmitting a high-frequency signal corresponding to the switch as an electromagnetic wave from the key plate 40 is embedded. The transmitter 36 also corresponds to the remote control device described in claim 1 (specifically, claim 4).

  The electric back door system 10 includes a receiver 46 that receives a high-frequency signal transmitted as an electromagnetic wave from the transmitter 36 (see FIG. 1). The receiver 46 is connected to the back door control unit 14 and also to the control unit of the keyless entry system (not shown). The receiver 46 demodulates the high frequency signal received from the transmitter 36 and is obtained by this demodulation. Information is output to the back door control unit 14 and the control unit of the keyless entry system. The back door control unit 14 and the control unit of the keyless entry system determine which switch provided in the transmitter 36 is turned on based on information input from the receiver 46 and turn it on as necessary. Perform processing according to the selected switch.

  Further, as shown in FIG. 2, a back door outside lever 48 that is operated when the back door 12 is pivotally moved in the opening direction is attached to the back door 12. There is provided a back door opener switch 50 (see FIG. 1) that is turned on in conjunction with the operation of the back door outside lever 48. The back door opener switch 50 is connected to the back door control unit 14. Further, as shown in FIG. 7, a back door close switch 52 that is turned on when the back door 12 is pivotally moved in the closing direction is provided at the lower end portion of the back door 12. The back door close switch 52 is also connected to the back door control unit 14. The back door outside lever 48, the back door opener switch 50, and the back door close switch 52 correspond to the opening / closing operation device according to claim 2, respectively. Further, the back door control unit 14 is connected with a touch sensor 54 for detecting when the back door 12 has a foreign object in between, and further connected with a buzzer 58 via a buzzer drive circuit 56.

  Next, as an operation of the present embodiment, a back door opening / closing control process executed by the back door control unit 14 will be described with reference to a flowchart of FIG. The back door opening / closing control process is provided in the opening / closing instruction switch 34 and the transmitter 36 provided in the instrument panel in a state where the main switch 32 provided in the instrument panel of the vehicle is turned on. When it is detected that any of the open / close instruction switch 44, the back door opener switch 50 provided on the back door 12, or the back door close switch 52 is turned on, the control is executed by the back door control unit 14.

  In the back door opening / closing control process, first, in step 70, whether or not the current state of the vehicle, the back door, and the electric back door system 10 satisfies the operating condition for opening and closing the back door 12 with the driving force of the drive motor 16. To determine. As this operating condition, in addition to the above-described main switch 32 being turned on, if the ignition switch of the vehicle is turned off, for example, the back door is unlocked, and the electric back door system 10 has an abnormality such as a disconnection. And the condition that the power supply voltage is a predetermined value (for example, 11 V) or more can be applied. If the ignition switch of the vehicle is on, in addition to the above conditions, for example, a condition such as the shift position being in the “P” range or the vehicle speed being a predetermined value (for example, 5 km / h) or less can be applied. . If the determination in step 70 is negative, no processing is performed (notifying means is activated to notify the operator who has performed the switch-on operation that the operating condition for opening and closing the back door is not satisfied. However, the back door opening / closing control process is terminated.

  On the other hand, if the determination in step 70 is affirmative, the routine proceeds to step 72 where it is determined whether or not the switch turned on by the operator is the back door opener switch 50 provided on the back door 12. The back door opener switch 50 is a switch that is turned on when the back door outside lever 48 for rotating the back door 12 in the opening direction is operated, and the back door opener switch 50 is turned on. In this case, it can be determined that the rotational movement of the back door 12 in the opening direction has been instructed. Therefore, if the determination in step 72 is affirmative, the process proceeds to step 86, and the drive motor 16 is driven after step 86 as described later. Then, the back door 12 is rotationally moved in the opening direction.

  If the determination in step 72 is negative, the process proceeds to step 74 to determine whether or not the switch turned on by the operator is the back door close switch 52 provided in the back door 12. The back door close switch 52 is a switch that is operated when the back door 12 is turned in the closing direction. When the back door close switch 52 is turned on, the back door 12 is turned in the closing direction. Therefore, if the determination in step 74 is affirmative, the process proceeds to step 80, and the drive motor 16 is driven in step 80 and later to rotate the back door 12 in the closing direction as will be described later. .

  If the opening / closing instruction switch 34 provided on the instrument panel of the vehicle or the opening / closing instruction switch 44 provided on the transmitter 36 is turned on, the determinations in steps 72 and 74 are denied and the routine proceeds to step 76. . Since the opening / closing instruction switches 34 and 44 have both a switch for instructing the rotational movement of the back door 12 in the closing direction and a switch for instructing the rotational movement of the back door 12 in the opening direction, the step In 76, the moving direction of the back door 12 instructed this time is determined. That is, first, it is confirmed whether the current position of the back door 12 is the fully open position or the fully closed position. If the current position of the back door 12 is the fully open position, the movement direction of the back door 12 instructed this time is determined as the closed direction. If the current position of the back door 12 is the fully closed position, the movement direction of the back door 12 instructed this time is determined as the opening direction.

  In the next step 78, the process branches according to the determination result of the moving direction in step 76. If it is determined that the instructed moving direction of the back door 12 is the closing direction, the process proceeds to step 80 and the back door 12 is rotated in the closing direction. When it is determined that the instructed moving direction of the back door 12 is the opening direction, the process proceeds to step 86 and the back door 12 is rotated in the opening direction.

  Next, details of the rotational movement of the back door 12 will be described. When the back door 12 is pivotally moved in the closing direction, first, in step 80, the buzzer 58 is sounded via the buzzer drive circuit 56 and the magnet clutch 28 is switched to the driving force transmission state. By driving the drive motor 16 via the motor drive circuit 18 so that the rotation shaft of the drive motor 16 rotates in the direction of rotational movement in the closing direction, the back door 12 is rotationally moved in the closing direction. In the electric back door system 10 according to the present embodiment, the turning movement direction of the back door 12 is reversed by turning on the opening / closing instruction switch 34 or the opening / closing instruction switch 44 during the turning movement of the back door 12. In the next step 82, it is determined whether or not the opening / closing instruction switch 34 or the opening / closing instruction switch 44 has been turned on to instruct whether the reverse movement direction of the back door 12 has been instructed. To determine.

  If the determination in step 82 is negative, the process proceeds to step 84, and it is determined whether or not the back door 12 has been pivotally moved in the closing direction (whether the back door 12 has reached the fully closed position). The determination in step 82 may be performed with reference to the result of detecting the current position of the back door 12 based on pulse signals input from the two Hall ICs of the door sensor 30, or the back door 12. A sensor for detecting whether or not is located at the fully closed position may be provided separately, and the output of the sensor may be referred to. If the determination in step 84 is also negative, the process returns to step 80, and steps 80 to 84 are repeated until the determination in step 82 or step 84 is affirmed.

  Although not clearly shown in FIG. 8, while the back door 12 is rotated in the closing direction by repeating Step 80 to Step 84, the back door control unit 14 is configured to use the two Hall ICs of the door sensor 30. Monitoring whether or not an overload is applied to the drive motor 16 based on the pulse signal input from the touch sensor 54 and monitoring whether or not the back door 12 has caught a foreign object based on the signal input from the touch sensor 54; When it is detected that an overload is applied to the drive motor 16 or when it is detected that the back door 12 has caught a foreign object, a process of stopping the drive motor 16 through the motor drive circuit 18 is also performed in parallel.

  If the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on before the back door 12 reaches the fully closed position, the determination in step 82 is affirmed. In this case, since the current rotational movement direction of the back door 12 is the closing direction, it can be determined that a reversal instruction for reversing the rotational movement direction of the back door 12 in the opening direction has been input. For this reason, when the determination in step 82 is affirmed, the process proceeds to step 86, and the back door 12 is rotated in the opening direction to reverse the rotational movement direction of the back door 12 as instructed. When the back door 12 reaches the fully closed position, the determination in step 84 is affirmed, and the back door opening / closing control process is terminated after switching the magnet clutch 28 to the driving force cutoff state.

  On the other hand, when the back door 12 is rotated in the opening direction, first, in step 86, the buzzer 58 is sounded via the buzzer drive circuit 56 and the magnet clutch 28 is switched to the driving force transmission state, and then the back door 12 is turned on. By driving the drive motor 16 via the motor drive circuit 18 so that the rotation shaft of the drive motor 16 rotates in a direction in which the rotary shaft 12 is rotated in the opening direction, the back door 12 is rotated in the opening direction. . In the next step 88, it is determined whether or not the reversal of the rotational movement direction of the back door 12 is instructed by determining whether the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on. If the determination in step 88 is negative, the process proceeds to step 94, and it is determined whether or not the rotational movement of the back door 12 in the opening direction has been completed (whether the back door 12 has reached the fully open position). Note that the determination in step 88 may be performed based on a pulse signal from the Hall IC of the door sensor 30, or a sensor for detecting whether or not the back door 12 is in the fully open position is provided, and the output of the sensor is provided. You may make it perform based on. If the determination in step 94 is also negative, the process returns to step 86, and steps 86, 88, and 94 are repeated until the determination in step 88 or step 94 is affirmed.

  If the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on before the back door 12 reaches the fully open position, the determination at step 88 is affirmed and the routine proceeds to step 90. In this case, since the current rotational movement direction of the back door 12 is the open direction, it can be determined that a reversal instruction for reversing the rotational movement direction of the back door 12 in the closing direction has been input. In the back door opening / closing control processing according to the above, in step 90, the current position (opening) of the back door 12 detected based on the pulse signal from the Hall IC of the door sensor 30 is taken in. It is determined whether the current opening degree of the door 12 (the opening degree of the back door 12 when the reverse instruction is input) is equal to or less than a predetermined value. If the opening degree of the back door 12 is larger than the predetermined value, the determination is denied and the routine proceeds to step 80. As described above, the back door 12 is pivoted in the closing direction in steps 80 to 84, so that the back door 12 The direction of the rotational movement of the door 12 is reversed as instructed.

  If the opening degree of the back door 12 when the reverse instruction is input is equal to or smaller than the predetermined value, the process proceeds to step 94 and returns to the loop of steps 86, 88, 94 to rotate the back door 12 in the opening direction. To continue. As described above, when the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on and the reverse instruction is input while the back door 12 is being rotated in the opening direction, the opening degree of the back door 12 is predetermined. Until the value becomes larger than the value, it is prohibited to reverse the direction of the rotational movement of the back door 12 in the closing direction in accordance with the input reverse instruction. As described above, Step 88 to Step 92 described above correspond to the prohibiting means according to the present invention (specifically, the prohibiting means described in claims 2 and 3), and the back door control unit 14 is prohibited according to the present invention. It corresponds to the means. Further, when the back door 12 reaches the fully open position, the determination in step 94 is affirmed, and after the magnet clutch 28 is switched to the driving force cut-off state, the back door opening / closing control process is terminated.

  Since the back door 12 is disposed at the rear end of the vehicle, the opening degree of the back door 12 that has been in the fully closed position has started to rotate in the opening direction is small (below a predetermined value). )), It is difficult for a person sitting in the driver's seat to recognize that the back door 12 is pivoting in the opening direction, and even if the person is located outside the vehicle, Depending on the position relative to the vehicle, it is difficult to recognize that the back door 12 of the vehicle is pivoting in the opening direction. For this reason, a person located near the rear end of the vehicle is seated in the driver's seat immediately after operating the back door outside lever 48 and instructing the rotational movement of the back door 12 in the opening direction. A person or person outside the vehicle carrying the transmitter 36 does not realize that the back door 12 has already started rotating in the opening direction, and the back door 12 is rotated in the opening direction. There is a possibility of performing an operation of turning on the opening / closing instruction switch 34 or the opening / closing instruction switch 44 in order to instruct dynamic movement. When this operation is performed, the back door control unit 14 of the electric back door system 10 rotates the back door 12 against the intention of the person who performed the operation to turn on the opening / closing instruction switch 34 or the opening / closing instruction switch 44. It is determined that the direction reversal (rotation movement to the fully closed position) is instructed.

  On the other hand, in this embodiment, when the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on and the reverse instruction is input while the back door 12 is being rotated in the opening direction, the back door 12 is turned on. Until the opening degree of the door 12 becomes larger than a predetermined value, it is prohibited to reverse the direction of the rotational movement of the back door 12 in the closing direction in accordance with the input inversion instruction. Contrary to the intention of the person who performed the operation of turning on the switch 44, the rotation movement direction of the back door 12 is reversed and prevented from rotating in the closing direction, and the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is prevented. Even if a small foreign object that is difficult for the person who turns on the vehicle to be present exists between the back door 12 and the vehicle body, the foreign object is caught between the back door 12 and the body. It is possible to prevent that. For example, even if the person who initially operated the back door outside lever 48 to instruct the rotational movement of the back door 12 in the opening direction grips the lower end of the back door 12 or the like, It is possible to prevent the hand from being pinched between the back door 12 and the body of the vehicle by unexpectedly reversing the moving direction. Considering this, the predetermined value as a threshold value in the determination in step 92 is an angle that can ensure safety when the rotation direction of the back door 12 is reversed (the reversal of the rotation movement direction of the back door 12 is started). Therefore, it is desirable to set the angle so that a person holding the lower end of the back door 12 can recognize it and retract his / her hand.

  In the above description, when a reverse instruction is input while the back door 12 is being rotated in the opening direction, it is determined whether or not the current opening degree of the back door 12 is equal to or less than a predetermined value, and the determination is denied. The direction of the rotational movement of the back door 12 is reversed only in accordance with the reversal instruction input only in the case of this, but the present invention is not limited to this, and the back door 12 is rotationally moved in the opening direction. When a reverse instruction is input midway, it is determined whether or not the switch that is the trigger for starting the rotational movement in the opening direction is the back door opener switch 50 or the back door close switch 52, and this determination is denied. (When the opening / closing instruction switch 34 or the opening / closing instruction switch 44 is turned on to start the rotational movement of the back door 12 in the opening direction), the current opening degree of the back door 12 is controlled. The direction of rotation movement of the back door 12 to Razz as directed may be reversing.

  Moreover, although the above demonstrated the aspect which applied the door sensor 30 which detects the opening degree of the back door 12 continuously as an opening degree detection means which concerns on this invention, it is not limited to this, For example, the back door 12 You may employ | adopt the structure (for example, switch etc.) which detects whether an opening degree is below a predetermined value.

  In the above description, the back door 12 is described as an example of the opening / closing body according to the present invention. However, the present invention is not limited to this, and the present invention includes a slide door, a swing door, a window, a luggage compartment door, a sunroof, and the like. It goes without saying that the present invention can be applied to any of the various opening / closing bodies.
