[0019]
In the present embodiment according to the above configuration, the operation when the slide door 4 is manually opened and closed, the mode is shifted to the power assist mode, and the automatic opening and closing control is performed will be described with reference to the flowchart shown in FIG.
[0020]
That is, when the automatic operation of the slide door 4 is started by the automatic opening / closing control, first, based on the inversion detection output 56 from the slide door rotation sensor 53, whether the slide door 4 has reached the fully open position or the fully closed position is determined. Is determined (S1), and if the full-open position or the fully-closed position is not reached, it is determined whether or not the opening operation is being performed (S2). If the opening operation is being performed, it is determined whether or not the slide door opening switch 62 is operated (S3). If the opening operation is being performed, the operation is shifted to the opening operation by the switch operation during the automatic opening and closing operation (S4). ). Specifically, when the slide door 4 is in the automatic operation, as shown in FIG. 5, the electromagnetic clutch 28 is turned on and the drive motor 31 is operated, and when the slide door open switch 62 is operated, The buzzer 52 sounds, the drive motor 31 is stopped while the electromagnetic clutch 28 is on, and a brake state is established (T1 in FIG. 5). After this state is continued and the slide door 4 is restrained and stopped for one second (T1 to T2 in FIG. 5), it is determined whether or not the slide door open switch 62 is operated (S5). If so, the process branches to step S1, and the opening operation of the slide door 4 is restarted (T2 in FIG. 5). If the slide door open switch 62 has not been operated, the drive motor 31 and the electromagnetic clutch 28 are turned off to perform an operation stop process (S6), and then the process ends.
[0021]
In step S3, if the slide door open switch 62 has not been operated, it is determined whether the slide door close switch 63 has been operated (S7). If not, the slide door close switch 63 has not been operated. The process branches to step S1 to continue the opening operation of the slide door 4, while if the closing operation has been performed, the process proceeds to the closing operation by a switch operation (S8). Specifically, when the slide door close switch 63 is operated, the buzzer 52 sounds, the drive motor 31 is stopped with the electromagnetic clutch 28 being on, and the brake state is continued for one second (FIG. T1 in 5). After this state is continued and the slide door 4 is restrained and stopped for one second (T1 to T2 in FIG. 5), it is determined whether or not the slide door close switch 63 is operated (S9), and the closing operation is performed. If so, the process branches to step S1 to close the slide door 4 (T2 in FIG. 5). That is, the driver may operate the slide door close switch 63 with the intention of turning the slide door 4 that is being opened and closing it. As an example of the operation, when the occupant starts power assist by opening the slide door 4 and sits on the seat before the slide door 4 is fully opened, the driver turns the slide door close switch 63 off. May operate. In such a case, the closing operation by the driver can be prioritized, so that the convenience is improved. If the slide door close switch 63 has not been operated in step S9, the drive motor 31 and the electromagnetic clutch 28 are turned off to perform an operation stop process (S6), and the process ends.
[0022]
If it is determined in step S2 that the slide door 4 is not being opened, it is determined whether the slide door 4 is being closed (S10). When the closing operation is not being performed, the process branches to step S1. On the other hand, when the closing operation is being performed, it is determined whether or not the slide door close switch 63 is operated (S11). As in step S8, the process proceeds to the closing operation by the switch operation, and after the buzzer 52 is sounded and the slide door 4 is restrained and stopped for one second (S12), it is determined whether or not the slide door close switch 63 is closed. Then, if the closing operation has been performed (S13), the process branches to the step S1 to restart the closing operation of the slide door 4 (T2 in FIG. 5). If the slide door close switch 63 has not been closed, the drive motor 31 and the electromagnetic clutch 28 are turned off to perform an operation stop process (S6), and the process ends.
[0023]
In step S11, if the slide door close switch 63 has not been operated, it is determined whether the slide door open switch 62 has been operated (S14). If not, the slide door open switch 62 has not been operated. The process branches to step S1 to continue the closing operation of the slide door 4, while if the opening operation has been performed, the operation proceeds to the opening operation by the switch operation as in step S4, and the slide door 4 is opened while the buzzer 52 sounds. After restraining and stopping for one second (S15), it is determined whether or not the slide door open switch 62 has been operated (S16). If the slide door open switch 62 has been operated, the process branches to step S1 and the slide door 4 is opened. Is opened (T2 in FIG. 5). That is, the driver may operate the slide door open switch 62 with the intention to turn the slide door 4 in the closing operation to open and open. As an example, when the driver notices that a foreign object such as luggage is caught in the slide door 4 while the slide door 4 is being closed, the driver turns the slide door 4 to the reverse position (opens). 62 may be operated. In addition, there is a case where it is desired to open the sliding door 4 during the closing operation not only in the case of pinching foreign matter but also in the normal automatic opening and closing. In such a case, the opening operation by the driver can be prioritized, so that the convenience is improved. If the slide door open switch 62 has not been operated, the drive motor 31 and the electromagnetic clutch 28 are turned off to perform an operation stop process (S6), and then the process ends.
[0024]
As described above, even when the automatic operation of the slide door 4 is started in the automatic opening / closing control, the operation by the slide door open switch 62 or the slide door close switch 63 can be prioritized. Also, regardless of which switch is operated in any direction (open / close), the operation of the slide door 4 is stopped by operating each of the switches 62 and 63 for a short time of less than 1 second. Therefore, it is possible to take out foreign substances such as luggage sandwiched between the slide doors 4. For this reason, the number of parts can be reduced and the circuit can be simplified as compared with the case where the auxiliary operation switch and the emergency reverse switch are provided near the door separately from the driver's seat. Further, since it is possible to prevent the user from wondering which of the plurality of switches should be operated, the convenience can be improved.
[0025]
On the other hand, by continuing to operate the switches 62 and 63 for more than a predetermined time, the slide door 4 can be restrained and stopped for one second and then moved in the direction corresponding to the switch operation. For this reason, it is possible to take out a foreign object such as a sandwiched luggage or the like during the restraint stop. Therefore, in order to prevent pinching, even if the switches 62 and 63 are to be operated for a short time and the switch is accidentally operated for one second or longer by mistake, the foreign matter can be easily taken out. In addition, while the slide door 4 is restrained and stopped, the driver can be notified that the slide door 4 has been operated by blowing the buzzer 52.
[0026]
Then, when shifting from the power assist in which the opening and closing of the slide door 4 is controlled based on the manual operation to the normal automatic opening and closing operation based on the operation of the switches 62 and 63, the switches 62 and 63 are set for more than one second. It is only necessary to continue the operation, and it is possible to eliminate the inconvenience of operating the switches 62 and 63 twice as in the related art.
[0027]
In the above-described embodiment, in the opening operation by the switch operation during the automatic opening and closing operation or the closing operation by the switch operation during the automatic opening and closing operation (steps S4, S8, S12, and S15), the drive motor 31 is stopped. A brake state is formed. However, the present invention is not limited to this, and control may be performed as follows. That is, when any of the operation switches 62 and 63 is operated, the operation direction of the current slide door 4 is first reversed by a predetermined distance (the current slide door 4 Then, the slide door 4 is restrained and stopped for a predetermined time, and the process of the next step is performed. In this case, the operation of the operation switches 62 and 63 is recognized as an emergency operation due to pinching, and the slide door 4 is first reversed so as to easily release the pinching state.
[0028]
Further, in the case of operating in the reverse direction in this way, the motor is always stopped for a predetermined time and then is operated in the reverse direction. Does not join. In addition, when stopped, the drive motor 31 is restrained while the electromagnetic clutch 28 is turned on, so that the slide door 4 can be prevented from moving under its own weight even on a slope or the like.
[0029]
【The invention's effect】
As described above, in the automatic sliding door control device of the present invention, the sliding door can be stopped by operating the switch in the driver's seat for a short period of time, and it is possible to take out foreign substances such as sandwiched luggage. Become. Therefore, the number of parts can be reduced and the circuit can be simplified as compared with a case where a sub-operation switch and an emergency reverse switch are provided near the door separately from the driver's seat. In addition, since it is possible to prevent the user from wondering which of the plurality of switches should be operated, it is possible to improve convenience.
[0030]
On the other hand, by continuing the switch operation beyond the predetermined time, the slide door can be moved in the direction corresponding to the switch operation after restraining and stopping the slide door for the predetermined time. For this reason, it is possible to take out a foreign object such as a sandwiched luggage or the like during the restraint stop. Therefore, even if the switch is to be operated for a short time and the switch is continually erroneously operated in order to prevent entrapment, the foreign matter can be easily taken out.
[0031]
Then, when shifting from power assist in which the opening and closing of the sliding door is controlled based on a manual operation to normal automatic opening and closing operation, it is only necessary to continuously operate the switch for more than a predetermined time. The inconvenience of operating can be eliminated.
