2 is provided, and the slide door 53 is slidably supported. The sliding door 53 is linked to a gear mechanism provided on a rotation shaft of a motor via a chain, a sprocket, etc. (not shown), and the closing direction C toward the front side FR of the vehicle body 51 by the motor and the rear part. It is adapted to be driven in the opening direction O toward the side RR.
Further, in the automatic slide door device that opens and closes the slide door 53 by using the motor as a drive source, the fully open limit switch 54 that is turned on when the slide door 53 reaches the fully open position Po and the fully closed position Pc are reached. There are provided a fully closed limit switch 55 which is turned on at this time, and an intermediate limit switch 56 which is turned on when an intermediate position Pn slightly before the fully closed position Pc is reached during the fully closed operation. Then, the power of the motor when the slide door 53 is fully opened or fully closed is turned off, while the power of the motor is turned off even at the middle open position Pn in which the intermediate limit switch 56 is turned on during the closing operation, and the slide door 53 is turned on. It is configured to stop once.

Further, in such an automatic slide door device, for example, in the case where the slide door 53 is started during the closing operation, the motor is stopped to stop the operation of the slide door 53 (actual opening 63). -148770
If the vehicle speed becomes higher than a predetermined value and the vehicle speed becomes higher than a predetermined value during the opening operation of the slide door 53, the motor is stopped to stop the operation of the slide door 53 ( It is known that the safety of the occupant is ensured by carrying out the method (see Japanese Utility Model Publication No. 2-125184).

[0004]

However, as described above, the operating conditions for permitting the opening and closing of the slide door 53 are satisfied, such as the vehicle is in a starting state or the vehicle speed is higher than a predetermined speed. Even when the slide door 53 is stopped when it disappears, the motor is simply stopped to stop the supply of the driving force to the slide door 53. Therefore, for example, when the operating condition is not satisfied on a steep slope or the like, the sliding door 53, which has stopped due to the supply of the driving force and stopped due to its own weight, slowly but opens. There was a risk of moving to O or the closing direction C.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide an automatic slide door stop control device for preventing movement of a slide door stopped during operation.

If not, it is determined that the operating conditions are not met.
It was decided.

In such a structure, the control of the slide door is
If the operating condition that allows the automatic opening / closing operation of the slide door , which is different from the starting condition that allows the start of control , is not satisfied, that is, the three operating conditions are not satisfied.
If neither of these is satisfied, the motor will stop and at the same time the motor will be electrically braked. Therefore, if the operating condition is not satisfied during the operation of the slide door, the motor is stopped and the brake force is generated, the movement of the slide door is restricted, and the drive force is not applied. Will be actively maintained.

According to the second aspect of the present invention, start condition determining means for determining whether or not a start condition permitting control start of the slide door is satisfied, and an operation signal of the operation switch are detected. After the operation signal detection means and the start condition determination means once determine that the start condition is satisfied, and then the operation condition determination means operates the operation condition while the operation signal is detected by the operation signal detection means.
If it is determined that the conditions are met, the start condition judgment
Even if it is determined by another means that the start condition is not satisfied, the control means is provided for continuing the automatic opening / closing operation of the slide door.

In such a structure, once the control of the slide door is started, any one of the three operating conditions is
If any one of them is satisfied , the automatic opening / closing operation of the slide door is continued if the operation switch is being operated at that time even when the start condition for permitting the control start of the slide door is not satisfied. .
