When the locking / unlocking signal from the normal / non-normal output determining unit 65 is input, the locking / unlocking output determining unit 66 is locked or unlocked based on the operating state of the sliding door from the sliding door operating state determining unit 64. It is determined whether unlocking is executed or not, and a lock request or unlock request is output to a door lock control device (not shown).
[0073]
[Operation of sliding door system]
Next, the operation of the sliding door system configured as described above will be described with reference to the flowcharts of FIGS.
[0074]
First, the operation of the keyless control device 2 will be described with reference to FIG. According to FIG. 5, when the command from the portable controller 1 is received by the receiving unit 61, the processing after step S <b> 1 is started, and whether or not the received command determining unit 62 is a command for opening or closing the sliding door. Is determined (step S1). When it is determined that a command for opening or closing the door has been received, the command and ID information are output to the reception command determination unit 62, the ID information is verified by the reception command determination unit 62, and the stored ID information and It is determined whether or not the ID information received in step S1 matches (step S2). When the stored ID information matches the ID information received in step S1, a command is output to the normal / non-normal output determination unit 65, and the normal / non-normal output determination unit 65 determines whether the slide door is operating. Is determined (step S3). When the normal / non-normal output determination unit 65 determines that the slide door is in operation, the slide door operation signal is output from the slide door operation signal output unit 67 to the drive determination unit 42 according to the output determination table, and the process is terminated. (Step S4).
[0075]
When the sliding door is not in operation in step S3, it is determined whether or not the switch operation time sent from the ID collating unit 63 by the normal / non-normal output determining unit 65 is a predetermined time (for example, 350 msec) or more (step S3). S5). When the normal / unusual output determination unit 65 determines that the switch operation time is equal to or longer than the predetermined time, the slide door operation signal is output from the slide door operation signal output unit 67 to the drive determination unit 42 according to the output determination table. The process ends (step S4).
[0076]
If the command for opening or closing the door is not received in step S1, if the ID information collation does not match in step S2, or if the switch operation time is not longer than the predetermined time in step S5, it is received. It is determined whether or not the received command is a command for locking the slide door (step S6). When it is determined that the received command is a command to be locked, processing similar to that in steps S2 and S3 is performed in steps S7 and S8. That is, when the ID information added to the received command matches the stored ID information and the sliding door is in operation, a sliding door operation signal is output (step S4). On the other hand, if it is not a command for locking the sliding door, if the ID information added to the received command does not match the stored ID information, or if the sliding door is not in operation, the process proceeds to step S9. Then, it is determined whether or not the received command is a command for unlocking the sliding door.
[0077]
When it is determined that the received command is a command for unlocking the slide door, the same processing as in steps S2 and S3 is performed in steps S10 and S11. That is, when the ID information added to the received command matches the stored ID information and the sliding door is in operation, a sliding door operation signal is output (step S4). On the other hand, if the command is not for unlocking the slide door, if the ID information added to the received command does not match the stored ID information, or if the slide door is not in operation, the process is terminated.
[0078]
By performing such processing, the keyless control device 2 can output a sliding door operation signal according to the output determination table to the drive determination unit 42.
[0079]
Next, the processing procedure of the drive determination unit 42 when the sliding door operation signal output from the keyless control device 2 is input as described above will be described with reference to FIG.
[0080]
First, it is determined whether or not the slide door operation signal has been received from the keyless control device 2 by the drive determination unit 42 (step S21), and when it is determined that the slide door has been received, the slide door is detected from the door position information from the door position determination unit 49. It is determined whether or not it is fully open (step S22). When it is determined that the slide door is not fully open, the process proceeds to step S23 and after, and when it is determined that the slide door is fully open, the process proceeds to step S29 and after.
[0081]
In step S23, the drive determination unit 42 determines that the portable controller 1 has been operated to operate the slide door in the opening direction, generates and outputs a drive determination signal, and when the slide door is opened. It is determined again whether or not a slide door operation signal is input from the keyless control device 2 (step S24). When a slide door operation signal is input again while the slide door is open, a determination content signal for closing the slide door is output to the drive direction determination unit 44. As a result, the drive determination unit 42 controls the reversal by operating the sliding door that has been operated in the opening direction in the closing direction.
[0082]
On the other hand, when the sliding door operation signal is not input again, it is determined whether or not the pinching is detected from the moving speed information from the door speed / operation direction calculating unit 46 (step S25). A determination content signal for closing the door is output to the drive direction determination unit 44. On the other hand, if pinching has not been detected, it is determined whether or not the slide door has reached the fully open position (step S26), and the processes in steps S23 to S26 are repeated until the slide door reaches the fully open position.
[0083]
When the slide door reaches the fully open position, the drive determination unit 42 outputs a determination content signal for stopping the slide door drive motor 11 (step S27), and controls to stop the slide door in the fully open state (step S28).
[0084]
When it is determined in step S22 that the slide door is not in the fully open position, when a slide door operation signal is input during the opening operation in step S24, or when pinching is detected in step S25, the drive determination unit 42 A determination content signal for closing the door is output to the drive direction determination unit 44 to start the closing operation of the slide door (step S29).
[0085]
Then, when the sliding door is closed, it is determined again whether or not the sliding door operation signal is input from the keyless control device 2 (step S30). If the slide door operation signal is input again while the slide door is open, a determination content signal for opening the slide door is output to the drive direction determination unit 44 (step S23). As a result, the drive determination unit 42 controls the inversion by operating the slide door that has been operated in the closing direction in the opening direction.
[0086]
On the other hand, when the sliding door operation signal is not input again, it is determined whether or not the pinching is detected from the moving speed information from the door speed / operation direction calculating unit 46 (step S31). A determination content signal for opening the door is output to the drive direction determination unit 44 (step S23). On the other hand, if pinching has not been detected, it is determined whether or not the slide door has reached the half latch position (step S32), and the processes of steps S29 to S32 are performed until the slide door reaches the half latch position. repeat.
[0087]
When the slide door reaches the half-latch position, the drive determination unit 42 outputs a determination content signal for stopping the slide door drive motor 11 (step S33), and controls to stop the slide door in the fully opened state (step S34). .
[0088]
In the above-described example, the case where the reverse operation is performed when any of the switches 51 to 54 of the portable controller 1 is operated during the opening operation or the closing operation has been described. However, the closing operation is performed. Only when the switch 51 to 54 of the portable controller 1 is operated only during the reverse operation may be performed.
[0089]
Further, in the above-described example, the case where the reversal operation is performed regardless of the position of the slide door has been described, but only when the slide door is located in a range where the pinch may occur, which is determined in advance by the drive determination unit 42. Alternatively, the reversal operation may be performed.
[0090]
[Effect of the embodiment]
As described above in detail, according to the sliding door system to which the present invention is applied, any one of the switches 51 to 54 of the portable controller 1 is operated when the sliding door is opened or closed. By outputting the slide door operation signal to the slide door control device 3 by the keyless control device 2, the slide door during the opening operation or the closing operation can be reversed. That is, according to this slide door system, the slide door can be reversed by operating any one of the switches 51 to 54 of the portable controller 1 while the slide door is operating.
[0091]
Therefore, according to this slide door system, when the user recognizes pinching or the like and performs the reverse operation of the slide door that is automatically opening and closing according to the operation of the portable controller 1, The speed can be increased.
[0092]
In addition, according to this slide door system, the slide door is caught when the switch 51-54 of the portable controller 1 is operated only during the closing operation so as to be reversed. Processing corresponding to the high possibility can be performed.
[0093]
Further, according to this slide door system, the drive judgment unit 42 performs the reversal operation only when the slide door is located outside the full open vicinity range and the full close proximity range of the slide door. Even if any one of the switches 51 to 54 of the portable controller 1 is operated as a control region of the door driving unit 5, it is possible to prevent the reversing operation from being performed.
[0094]
Furthermore, according to this slide door system, the ID information added to the command of the portable controller 1 and the ID information stored in advance in the processing in steps S2, S7, and S10 of FIG. Since the sliding door is reversed only when the two are matched, it is possible to prevent the sliding door from being actuated by receiving a radio signal from the portable controller 1 of another vehicle.
[0095]
Furthermore, according to this slide door system, when the slide door is in operation as shown in FIG. 4, the slide door operation signal for operating the slide door is generated even if the operation time of each of the switches 51 to 54 is short. Since the slide door can be reversed and generated, the time from the operation of the portable controller 1 to the reverse operation can be shortened, and the speed of the operation can be further improved.
[0096]
The above-described embodiment is an example of the present invention. For this reason, the present invention is not limited to the above-described embodiment, and various modifications can be made depending on the design and the like as long as the technical idea according to the present invention is not deviated from this embodiment. Of course, it is possible to change.
[0097]
