[0036]
The vehicle 1 includes a known room lamp that is turned on when the slide door 4 is opened and turned off when the slide door 4 is fully closed. The room lamp is in the state of the slide door switch 234. It is configured to be turned on / off accordingly.
[0037]
In the present embodiment according to the above configuration, the operation when the sliding door 4 in the fully open position is closed will be described according to the flowchart shown in FIG. In the state where the sliding door 4 is in the fully open position, as shown in FIG. 7A, the rear thrust roller 91a of the lower roller 91 of the lower roller bracket 14 that moves in the lower guide rail 13 is a check link 96. Is in contact with the check link 96 in a state of crossing to the open side.
[0038]
The rear thrust roller 91a gets over the check link 96 when the sliding door 4 is opened, and the contact surface 92 of the lower roller bracket 14 is brought into contact with the full opening stopper 93 provided at the rear end of the lower guide rail 13. The drive motor 72 stops after reaching the contact position ((b) of FIG. 7).
[0039]
Next, the drive motor 72 reverses with a slight force (low speed) with a reduced duty ratio, and returns to a position ((a) in FIG. 7) that is in contact with or close to the check link 96 (low power operation in the closing direction).
[0040]
In this state, the opening operation is completed, the drive motor 72 is stopped (OFF), the electromagnetic clutch 64 is disconnected (OFF), and the slide door 4 is held by the check link 96 in the fully open position.
[0041]
In this state, when the slide door close switch 233 provided on the instrument panel or the remote control close switch is operated to receive a close operation command, first, pulses from the slide door rotation sensor 223 are added or subtracted. It is determined from the accumulated number of pulses whether the slide door 4 is stopped at the fully open position (S1). If it is not the fully open position, the process branches to step S5 to perform a normal closing operation. This closing operation is controlled at a constant speed that is closed at a constant speed. On the other hand, if the electromagnetic clutch 64 has been stopped at the fully open position, the electromagnetic clutch 64 is brought into a connected state, a drive pulse with a duty ratio of 100% is output to the drive motor 72, and the slide door 4 is set for a predetermined time, Drive in the opening direction and stop (S2). Then, as shown in FIG. 7B, the rear thrust roller 91a is moved to a position away from the check link 96 in the opening direction.
[0042]
At this time, since the rear thrust roller 91a is in contact with the check link 96, the contact surface 92 of the lower roller bracket 14 contacts the fully open stopper 93 at the rear end of the lower guide rail 13 for the predetermined time. It is assumed that sufficient time is listed and this time is set. Therefore, whether the rear thrust roller 92a is in contact with or apart from the check link 96, as shown in FIG. The abutment surface 92 can move until it abuts against the fully open stopper 93.
[0043]
Further, since a drive pulse with a duty ratio of 100% is applied to the drive motor 72, the output from the drive motor 72 during the movement in the opening direction is maintained at the maximum. For this reason, an increase in the operating resistance of the drive transmission mechanism 75 due to the sliding resistance of the drive cable at low temperature (−25 ° C.) or the operating resistance of the drive transmission gear or the high weight due to the door's own weight when the vehicle stops on the slope down in the door closing direction. It is possible to compensate for an output shortage at the time of load or when the motor output is reduced due to a low voltage. Therefore, the lower roller 91 can be reliably moved in the opening direction.
[0044]
Further, the movement of the rear thrust roller 91a in the opening direction is stopped after a predetermined time has elapsed. Here, since the stop of the movement in the opening direction is after a predetermined time has elapsed, for example, when the cumulative pulse number changes, the contact surface 92 of the lower roller bracket 14 contacts the full-open stopper 93. In such a case, the amount of change in the cumulative number of pulses cannot be obtained, and stop processing cannot be performed. Such a problem can be avoided.
[0045]
Next, a drive pulse with a duty ratio of 100% is output to the drive motor 72 to reversely rotate (actuate in the closing direction) to drive the sliding door 4 in the closing direction (S3), and from the accumulated pulse number, the fully open area A ( It is determined whether or not the process exits (FIG. 7) (S4). Then, as shown in FIGS. 7C and 7D, the rear thrust roller 91a is moved in the closing direction until it passes over the check link 96 and passes through the fully open area A.
[0046]
As described above, when the sliding door 4 in the fully open position is closed, after the slide door 4 is once driven in the opening direction, the driving of the lower roller 91 in the fully open area A is started in order to start driving in the closing direction. Even when the rear thrust roller 91a is stopped in contact with or close to the check link 96 as shown in FIG. 7A, the rear thrust roller 91a is As shown in FIG. 7B, after moving away from the check link 96 to the position away from the opening direction, the driving in the closing direction is started as shown in FIGS. 7C and 7D. be able to.
[0047]
Therefore, the moving speed of the rear thrust roller 91a can be accelerated until the rear thrust roller 91a of the lower roller 91 reaches the check link 96 (see FIGS. 7B to 7C). The check link 96 can be overcome by the momentum. Therefore, the closing operation can be started smoothly as compared with the conventional case where the check link 96 is difficult to get over and the closing operation is difficult. Therefore, the uncomfortable feeling during the closing operation can be eliminated.
[0048]
At this time, since a drive pulse with a duty ratio of 100% is applied to the drive motor 72, the drive motor 72 starts from the drive motor 72 until the rear thrust roller 91 a moved in the closing direction passes over the check link 96. The output of is maintained at a maximum. For this reason, the constant speed control for moving the slide door 4 at a constant speed can be prevented from suppressing the output from the drive motor 72 as in the case where the control is started from this point. Can be made more reliable.
[0049]
In addition, it is possible to compensate for an output shortage due to a reduction in the motor output due to a low load due to an operating resistance of the drive transmission mechanism 75 at a low temperature or a high load due to the door's own weight on a slope down the door closing direction.
[0050]
Here, the determination of the end of the driving process in the closing direction by the driving pulse having a duty ratio of 100% is made based on the cumulative number of pulses. This is because when the vehicle is stopped on a hill, the moving speed of the slide door 4 varies greatly depending on the inclination angle, so that the determination by the timer becomes impossible.
[0051]
When the rear thrust roller 91a gets over the check link 96 and passes through the fully open area A (FIG. 7), the drive pulse to the drive motor 72 is moved so that the slide door 4 moves at a constant speed. The constant speed control for controlling the duty ratio is performed (S5), and the process returns to the main routine. This constant speed control prevents a speed change such as an increase in the door speed during the closing operation, even on a slope down to the door closing side, a slope down to the door opening side, or a flat road. Can be moved at a constant speed.
[0052]
【The invention's effect】
As described above, in the automatic sliding door control device according to claim 1 of the present invention, when the sliding door in the fully opened position is closed, the sliding door is once driven in the opening direction and then moved in the closing direction. In order to start driving, even when the roller that has passed over the full-open checker is stopped at the full-open position close to the full-open checker, the roller is once moved to a position away from the full-open checker in the opening direction. After that, driving in the closing direction can be started.
[0053]
Therefore, the moving speed of the roller can be accelerated until the roller reaches the fully open checker, and the fully open checker can be overcome by the momentum. Therefore, the closing operation can be started smoothly compared to the conventional case where it is difficult to get over the full opening checker and the closing operation is difficult. Therefore, the uncomfortable feeling during the closing operation can be eliminated.
[0054]
In the automatic sliding door control device according to the second aspect, the output from the motor can be maintained at the maximum until the roller passes over the fully open checker. For this reason, as in the case where control for moving the sliding door at a constant speed is started, it is possible to prevent the output from the motor from being suppressed, and to make the passage of the fully open checker more reliable. it can.
[0055]
In addition, it is possible to compensate for an output shortage due to a reduction in the motor output due to a low load due to a high load due to the operating resistance of the drive transmission mechanism at a low temperature or due to the door's own weight on a slope down the door closing direction.
[0056]
When the roller passes over the fully open checker, the output of the drive pulse to the motor is controlled so that the slide door moves at a constant speed. Thereby, a speed change such as an increase in speed during the closing operation can be prevented.
[0057]
Furthermore, in the automatic slide door control device according to the third aspect, the output from the motor can be maintained at the maximum when the roller is once moved to a position away from the fully open checker in the opening direction. As a result, it is possible to compensate for an output shortage due to a reduction in motor output caused by a low load caused by a high load due to the operating resistance of the drive transmission mechanism at a low temperature or due to the door's own weight on a slope that has lowered in the door closing direction. Accordingly, the roller can be reliably moved in the opening direction.
