JP 09-170374 A

  By the way, it is conceivable to employ a motor to automatically open and close each door. For example, when the upper door is automatically opened and closed by a motor, the upper door is closed when an engagement state between a striker provided at the upper end of the lower door and a closer provided at the lower end of the upper door is detected. It is conceivable to stop driving the motor. In this case, even if the motor is driven so that the upper door is closed when the lower door is not closed, the lower door striker and the upper door closer do not engage with each other, so the upper door is closed. The drive of the motor will not be stopped. For this reason, there is a possibility that the upper door that is closed by the drive of the motor is unnecessarily pressed against the vehicle body and is damaged.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a vehicle opening / closing device that prevents unnecessary driving of a motor that opens and closes a door.

In order to achieve the above object, in the vehicle opening / closing device according to claim 1, the first door (30) for opening and closing a part (11a) of the opening (11) of the vehicle body (10). And the second door (40) that opens and closes the other part (11b) of the opening, which is a part excluding the part opened and closed by the first door, in accordance with the drive of the motor (51). And a vehicular opening and closing device (20) for closing the other part of the opening by the second door after the part of the opening is closed by the first door according to the driving of the motor And detecting means (72, 73) for detecting a closed state in which a part of the opening is closed by the first door, and driving the motor when the closed state is detected by the detecting means. second control means for allowing the closing operation of the door by the (60), said first At least one locking means for fixing the door to the vehicle body and closing a part of the opening. The detection means fixes the first door to the vehicle body by the locking means. the in and state, and technical features that you detected as the closed state.

According to the first aspect of the present invention, the control means enables the second door to be closed by driving the motor when the detection means detects a closed state of a part of the opening by the first door. Thereby, the closing operation according to the drive of the motor of the 2nd door when the 1st door is not a closed state can be prevented.
Therefore, unnecessary driving of the motor that opens and closes the door can be prevented.

In particular , the detection means detects a state in which the first door is fixed to the vehicle body by the lock means as a partially closed state of the opening. Accordingly, it is possible to reliably detect a state in which a part of the opening is closed by the first door, and to reliably prevent unnecessary driving of the motor.

In the invention of claim 2 , the first door is a lower door that opens and closes a lower opening that is a part of the opening, and the second door is an upper opening that is the other part of the opening. It is an upper door that opens and closes. Thus, you may comprise a 1st door and a 2nd door.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a partial front view of a vehicle to which a vehicle opening / closing device 20 according to this embodiment is applied as viewed from the rear. FIG. 2 is a schematic side view showing a state in which the upper door 40 of the vehicle opening / closing device 20 is opened. FIG. 3 (A) is an explanatory view showing a state of the left side lock mechanism 33a before engagement, and FIG. 3 (B) is an explanatory view showing a state where the left side lock mechanism 33a is engaged with the left engagement portion. is there. FIG. 4 is a block diagram showing a control configuration of the ECU 60 of the vehicle opening / closing device 20.

  As shown in FIGS. 1, 2, and 4, the vehicle opening / closing device 20 is a device that opens and closes the opening 11 of the vehicle body 10, and is below the opening 11 (hereinafter also referred to as a lower opening 11 a). ), An upper door 40 that opens and closes the upper side of the opening 11 (hereinafter also referred to as the upper opening 11b), a driving device 50 that automatically opens and closes the upper door 40, and the driving device 50 And an ECU (Electronic Control Unit) 60 for controlling the driving.

  The vehicle opening / closing device 20 is configured to close the upper opening 11b with the upper door 40 after closing the lower opening 11a with the lower door 30, and the upper end of the lower door 30 in the closed state. The striker 31 provided so as to protrude upward is engaged with the closer 41 provided inside the lower end of the upper door 40, so that the opening 11 is fully closed by the lower door 30 and the upper door 40. Has been.

  As shown in FIG. 1, the lower door 30 is hinged to the lower edge of the lower opening 11 a by two hinges 32 at the lower edge, thereby lowering the lower door 30 around the hinge axis (not shown). It is rotatably supported from a position (closed state) for closing the opening 11a to a predetermined open position (open state) outward. The lower door 30 is configured to be manually opened and closed by a driver or the like.

  A left side lock mechanism 33a and a right side lock mechanism 33b are provided at both ends on the lower opening 11a side of the lower door 30, respectively. When both locking mechanisms 33a and 33b are engaged with the left and right engaging portions (not shown) provided at the left and right edges of the lower opening 11a, respectively, The opening 11 a is closed by the lower door 30.

  The engagement relationship between the left lock mechanism 33a and the left engagement portion and the engagement relationship between the right lock mechanism 33b and the right engagement portion are the same engagement relationship. The engagement relationship with the left engagement portion will be described.

  As shown in FIG. 3A, the left lock mechanism 33a mainly includes a latch 34 that is rotatably supported, a pole 35 that rotates in accordance with the rotation of the latch 34, and a left engagement portion. The groove portion 36 is formed so as to be able to receive the striker 12. If the left lock mechanism 33a is in a state before being engaged, the latch 34 and the pawl 35 are located at the rotation position shown in FIG.

  When the lower opening portion 11a is manually closed by the lower door 30 by a driver or the like, the striker 12 of the left engagement portion is relatively set to the groove portion 36 of the left lock mechanism 33a and the notch portion 34a of the latch 34. enter in. Then, the latch 34 is pressed by the striker 12 and rotates counterclockwise in the figure, and the pole 35 rotates in the clockwise direction in the figure.

  As shown in FIG. 3 (B), the end 35a of the pole 35 abuts the notch 34a of the latch 34 so as to restrict the clockwise rotation of the latch 34, whereby the striker 12 is The latch 34 and the groove 36 are engaged. As a result, the left lock mechanism 33a and the left engagement portion are engaged.

  Such engagement between the left side lock mechanism 33a and the left side engagement portion and engagement between the right side lock mechanism 33b and the right side engagement portion are caused by the operation of the engagement release lever (not shown) to the end of the pole 35. When the rotation restriction of the latch 34 by the portion 35a is released, the lower door 30 becomes openable. Both the lock mechanisms 33a and 33b and the both side engaging portions are not limited to the above-described configuration, and the lower door 30 is opened downward so that the lower opening 11a is closed by the lower door 30. What is necessary is just the structure engaged with the edge of the part 11a.

  The upper door 40 is hinged to the upper edge of the upper opening 11b by two hinges 42 at its upper edge, thereby closing the upper opening 11b around the hinge axis (not shown) From a state) to a predetermined open position (open state) outward. The upper door 40 in the open state is supported by a pair of left and right dampers 43 provided on both sides of the opening 11 so as not to rotate further outward than the predetermined open position (see FIG. 2).

  As shown in FIG. 2, the drive device 50 is fixed to the motor 51, a speed reduction mechanism 52 that reduces the rotational speed of the motor 51 and increases the rotational torque, and an output shaft of the speed reduction mechanism 52 so as not to be relatively rotatable. The arm 53 that rotates about the output shaft according to the rotational torque increased by the speed reduction mechanism 52 and the rod 54 that is rotatably connected to the tip of the arm 53 are provided. The motor 51 is provided with a Hall IC 51a that detects a load fluctuation or rotation state during rotation and outputs the detected load to the ECU 60.

  The driving device 50 rotates the arm 53 in the opening operation direction around the output shaft of the speed reduction mechanism 52 by the motor 51 that rotates in the opening operation direction according to the opening operation motor voltage supplied from the ECU 60. Thereby, the rod 54 rotates in the direction (opening operation direction) away from the arm 53 at the tip of the arm 53 to open the upper door 40.

  Further, the driving device 50 rotates the arm 53 in the closing operation direction around the output shaft of the speed reduction mechanism 52 by the motor 51 that rotates in the closing operation direction in accordance with the closing operation motor voltage supplied from the ECU 60. As a result, the rod 54 rotates in the direction approaching the arm 53 (the closing operation direction) at the tip of the arm 53 to close the upper door 40.

Next, an electrical configuration of the ECU 60 responsible for driving control of the motor 51 constituting the driving device 50 will be described with reference to FIG.
As shown in FIG. 4, the ECU 60 is electrically connected to an operation switch 71, a first detection sensor 72, a second detection sensor 73, a Hall IC 51 a, and the motor control that drives and controls the motor 51. Processing is in progress.

  Here, the operation switch 71 is provided, for example, on a console panel in the vehicle compartment, and outputs an opening operation signal to the ECU 60 when the operation is performed to open the upper door 40, thereby closing the upper door 40. When operated in this manner, it plays a role of outputting a closing operation signal to the ECU 60.

  In addition, the first detection sensor 72 is configured to lock the left-side lock when the striker 12 of the left-side engagement portion is engaged with the latch 34 and the groove 36 of the left-side lock mechanism 33a. For example, the mechanism 33a is provided in the vicinity of the left engaging portion so as to detect that the mechanism 33a is engaged with the left engaging portion.

  The first detection sensor 72 plays a role of outputting a first closed state signal to the ECU 60 when such an engagement state is detected. The first detection sensor 72 is not limited to detecting the engagement state based on the above-described rotation restriction state of the latch 34, and any one of the rotation positions of the latch 34 and the pole 35, It may be a detection sensor that detects the engagement state according to the relative position.

  In addition, the second detection sensor 73 detects the state in which the latch 34 is restricted from rotating by the pole 35 when the striker 12 of the right engagement portion is engaged with the latch 34 and the groove portion 36 of the right lock mechanism 33b. For example, the mechanism 33b is provided in the vicinity of the right engaging portion so as to detect that the mechanism 33b is engaged with the right engaging portion.

  The second detection sensor 73 serves to output a second closed state signal to the ECU 60 when such an engagement state is detected. Note that the second detection sensor 73 is not limited to detecting the engagement state based on the above-described rotation restriction state of the latch 34, and any one of the rotation positions of the latch 34 and the pole 35, It may be a detection sensor that detects the engagement state according to the relative position.

  The operation of the ECU 60 will be specifically described. When an opening operation signal is input from the operation switch 71, the ECU 60 applies a predetermined opening operation motor voltage for opening the upper door 40 to the motor 51 by the motor drive circuit. Supply. Further, when the closing operation signal is input from the operation switch 71 and the first closed state signal of the first detection sensor 72 and the second closed state signal of the second detection sensor 73 are input, the ECU 60 opens the upper door 40. A predetermined motor voltage for closing operation for closing is supplied to the motor 51 by the motor drive circuit.

  With this configuration, the vehicle opening / closing device 20 automatically opens and closes the upper door 40 with the motor 51 of the driving device 50 controlled by the ECU 60 in accordance with the operation of the operation switch 71.

  By the way, when detecting the engagement state between the striker 31 of the lower door 30 and the closer 41 of the upper door 40, the driving of the motor 51 that opens and closes the upper door 40 is stopped when the upper door 40 is in a closed state. When the motor 51 is driven so that the upper door 40 is closed when the door 30 is not in the closed state, the striker 31 of the lower door 30 and the closer 41 of the upper door 40 do not engage with each other, so the upper door 40 is closed. Even if it becomes, the drive of the motor 51 will not be stopped. For this reason, there is a possibility that the upper door 40 that is closed by the driving of the motor 51 is unnecessarily pressed against the vehicle body and is damaged.

  Therefore, the ECU 60 in the vehicle opening / closing device 20 according to the present embodiment controls the motor 51 based on the flowcharts shown in FIGS. 5 and 6 described below, so that the motor 51 is only in the case where the lower door 30 is in the closed state. Can be driven. Hereinafter, in the vehicle in which the upper door 40 is in the opened state, the flow of calculation processing in the motor control processing by the ECU 60 will be described in detail based on the flowcharts shown in FIGS. 5 and 6.

  First, in step S101 in FIG. 5, it is determined whether or not a closing operation signal by the operation of the operation switch 71 is input, and the determination of No is repeated until the closing operation signal is input to the ECU 60. In this state, when a closing operation signal is input by operating the operation switch 71 (Yes in S101), it is determined in step S103 whether or not the first closing state signal from the first detection sensor 72 is input. The

  Here, if the left lock mechanism 33a is not engaged with the left engagement portion and the first closed state signal is not input from the first detection sensor 72 (No in S103), the determination process from step S101 is repeated. It is.

  On the other hand, when the left lock mechanism 33a is engaged with the left engagement portion and the first closed state signal is input from the first detection sensor 72 (Yes in S103), in step S105, the second detection sensor 73 It is determined whether or not the second closed state signal is input.

  Here, if the right lock mechanism 33b is not engaged with the right engagement portion and the second closed state signal is not input from the second detection sensor 73 (No in S105), the determination process from step S101 is repeated. It is.

  On the other hand, when the right lock mechanism 33b is engaged with the right engagement portion and the second closed state signal is input from the second detection sensor 73 (Yes in S105), it is determined that the lower door 30 is in the closed state. In step S107, a closing operation process is performed.

  In this closing operation process, the ECU 60 supplies the predetermined closing operation motor voltage to the motor 51 by the motor drive circuit. Accordingly, the driving device 50 causes the arm 53 and the rod 54 to rotate in the closing operation direction by the motor 51 that rotates in the closing operation direction, thereby closing the upper door 40.

  Whether the lower door 30 is opened by the driver or the like during the closing operation process as described above, and the first closed state signal is not input due to the release of the engagement between the left lock mechanism 33a and the left engagement portion, If the second closed state signal is not input by releasing the engagement between the right lock mechanism 33b and the right engagement portion (No in S109 or No in S111), the opening operation process is performed in Step S119 of FIG. Made.

  Further, during the closing operation as described above, if an obstacle such as a luggage is sandwiched between the upper door 40 and the upper opening 11b and the closing operation of the upper door 40 is suppressed, the motor 51 is overloaded. Thus, based on the detection signal from the Hall IC 51a, it is determined as Yes in step S113 as being in the motor overload state. With the determination of Yes, an opening operation process is performed in step S119 of FIG.

  If the closer 41 of the upper door 40 is engaged with the striker 31 of the lower door 30 during the closing operation as described above, the opening 11 is completely closed by the upper door 40 and the lower door 30 in step S115. It is determined as Yes. With the determination of Yes, in step S129 of FIG. 6, which will be described later, the motor 51 is stopped and the motor control process is ended by ending the closing operation of the upper door 40.

  If an opening operation signal is input from the operation switch 71 during the closing operation process as described above, it is determined Yes in step S117, and the opening operation process is performed in step S119 of FIG.

  In the opening operation process in step S119, the ECU 60 supplies the predetermined opening operation motor voltage to the motor 51 by the motor drive circuit. Thereby, the drive device 50 rotates the arm 53 and the rod 54 in the opening operation direction by the motor 51 rotating in the opening operation direction, and opens the upper door 40.

  If the closing operation signal from the operation switch 71 is input during the opening operation processing as described above, it is determined Yes in step S121, and the processing from step S107 in FIG. 5 is performed.

  On the other hand, when the upper door 40 opens to the open position during the opening operation process as described above, it is determined Yes in step S122, and in step S129, the drive stop process of the motor 51 is performed, and both dampers 43 The opening operation of the upper door 40 is suppressed. On the other hand, when the upper door 40 is not in the open position (No in step S122) and the upper door 40 is in contact with an obstacle such as a wall and the opening operation of the upper door 40 is suppressed, the motor 51 is overloaded. Based on the detection signal from the Hall IC 51a, it is determined that the motor is overloaded in Step S123.

  Thus, when it is determined Yes in step S123, the first closed state signal is not input due to the disengagement between the left lock mechanism 33a and the left engagement portion, or the right lock mechanism 33b and the right engagement If the second closed state signal is not input due to the disengagement with the unit (No in S125 or No in S127), in step S129, the driving stop process of the motor 51 is performed and the opening / closing operation of the upper door 40 is performed. By ending the process, the motor control process ends.

  On the other hand, when both the first closed state signal and the second closed state signal are input (Yes in S125 and Yes in S127), the processing from step S107 in FIG. 5 is performed.

  In the flow from step S101 described above, the vehicle in which the upper door 40 is in the open state has been described. However, for the vehicle in which both the lower door 30 and the upper door 40 are in the closed state, an opening operation signal from the operation switch 71 is provided. 6 after releasing the engagement between the striker 31 of the lower door 30 and the closer 41 of the upper door 40, the processing from step S119 of FIG. 6 may be performed.

As described above, in the vehicle opening / closing device 20 according to the present embodiment, the ECU 60 detects the closed state of the lower opening portion 11a by the lower door 30 by the first detection sensor 72 and the second detection sensor 73. At this time, the upper door 40 can be closed by driving the motor 51 of the driving device 50. Thereby, the closing operation of the upper door 40 when the lower door 30 is not in the closed state can be prevented.
Therefore, unnecessary driving of the motor 51 that opens and closes the upper door 40 can be prevented.

  Further, in the vehicle opening / closing device 20 according to the present embodiment, the first detection sensor 72 and the second detection sensor 73 are configured such that the left lock mechanism 33a engages the left engagement portion and the right lock mechanism 33b includes the right engagement portion. The state in which the lower door 30 is fixed to the vehicle body 10 by both the lock mechanisms 33a and 33b is detected as the closed state of the lower opening 11a by the lower door 30. Accordingly, it is possible to reliably detect the state in which the lower opening portion 11a is closed by the lower door 30 and reliably prevent unnecessary driving of the motor 51.

  Further, in order to prevent interference between the striker 31 of the lower door 30 and the lower end portion of the upper door 40 when the lower door 30 is closed after the upper door 40 is closed, as described in Patent Document 1 described above. In addition, when the open / close state of each of the upper door 40 and the lower door 30 is detected and the lower door 30 is in the open state and the upper door 40 is in the closed state, the stopper shaft is placed between the vehicle body and the lower door 30. It is conceivable to provide a stopper mechanism to be interposed between the two. However, the provision of the stopper mechanism as described above not only increases the number of parts such as the stopper shaft, but also reduces the degree of design freedom in the vehicle body and the like because the stopper mechanism is disposed at a predetermined position.

  In the vehicle opening / closing device 20 according to the present embodiment, the closing operation of the upper door 40 in the case where the lower opening 11a is not closed by the lower door 30 only by control by the ECU 60 without providing such a stopper mechanism. Can prevent. Thereby, interference between the lower door 30 and the upper door 40 can be prevented without increasing the number of parts and without reducing the degree of freedom of design.
