(Operation Example 1) Next, referring to the flowcharts shown in FIGS. 4 to 8, when the slide door 3 is fully closed, the wireless remote controller 4 or the door open switch 19 opens the slide door 3. An operation when a door instruction is given will be described.

First, an operation example 1 will be described with reference to a flowchart shown in FIG. When the above-mentioned door opening instruction is given,
The switch element TR3 in the control circuit 11a turns on, a current flows through the relay coil of the actuator control relay 11f, and the contact switch closes. When the contact switch closes,

Since the other end of the door 35 is grounded, the release ACT 35 is activated, and the door lock 34 is unlocked in a direction to unlock the door lock mechanism 5.
Is driven (step S1).

If the door lock mechanism 5 is not in the locked state, the door lock mechanism 5 is unlocked, and the slide door 3 is pushed outward by the reaction force of the seal rubber, and moves in the opening direction. The movement of the sliding door 3 in the opening direction is detected by turning on the half-door switch 24 (step S).
2).

When the sliding door 3 is opened more than the half door, the control circuit 11a controls the transistor 11c,
The electromagnetic clutch 12e is switched from the disconnected state to the connected state. Thereby, the opening / closing motor 12f and the drive pulley 12a are connected via the electromagnetic clutch 12e (step S3).

In this state, when the switch element TR1 in the control circuit 11a is turned on and a current flows through the relay coil of the motor control relay 11d to close the contact switch, one end of the open / close motor 12f is connected to the battery 15. Since the other end of the open / close motor 12f is already connected to the transistor 11g via the motor control relay 11e, when the transistor 11g is turned on by the control circuit 11a, the open / close motor 12f drives the slide door 3 in the opening direction. (Step S4).

The power of the opening / closing motor 12f is supplied to the electromagnetic clutch 1
The transmission is transmitted to the cable member 12c via the drive pulley 2e and the drive pulley 12a, and the slide door 3 is driven in the opening direction via the moving member 12d.

When the slide door 3 reaches the full open position and the full open detection switch 25 is turned on (step S5), the control circuit 11a turns off the switch element TR1 to cut off the current flowing through the relay coil of the motor control relay 11d, and the contact Open the switch. Thus, the rotation of the opening / closing motor 12f is stopped, and the movement of the slide door 3 is stopped (step S6).

If the half-door switch 24 has not been turned on in step S2, it is determined that the door lock mechanism 5 is in the no-lock state, and the process ends without automatically opening the slide door 3 by the driving source. .

(Operation Example 2) Next, an operation example 2 will be described with reference to the flowchart shown in FIG. The processing procedure shown in FIG. 5 differs from the processing procedure shown in FIG. 4 in that the detection of the movement of the sliding door 3 in the opening direction is performed by using pulse signals φ1 and φ2 from the rotary encoder 12g instead of the half-door switch 24.
(Step S2a)

(Operation Example 3) Next, an operation example 3 will be described with reference to a flowchart shown in FIG. The processing procedure shown in FIG. 6 is different from the processing procedure shown in FIG. 4 when the vehicle stops on a downhill or when the seal rubber deteriorates and the sliding door 3
This is a processing procedure corresponding to a case where is not pushed back by a reaction force.

That is, in step S2, the sliding door 3
In the case where the detection of the movement in the opening direction cannot be detected by turning on the half-door switch 24, it is determined that the door lock mechanism 5 is in the no-lock state in the processing procedure of FIG.

However, even when the door lock mechanism 5 is unlocked, the slide door 3 may not move when the vehicle stops on a downhill or when the seal rubber is deteriorated. Therefore, the control circuit 11a sets the transistor 11c
Is controlled to switch the electromagnetic clutch 12e from the disconnected state to the connected state, and the open / close motor 12f and the drive pulley 12a are connected (step S11).

Then, the switch element TR1 is turned on, the contact switch of the motor control relay 11d is closed, and one end of the open / close motor 12f is connected to the battery 15 and the other end is connected to the transistor 11g via the motor control relay 11e. Switch to

Next, the control circuit 11a sets the transistor 1
By controlling 1g, the opening / closing motor 12f is controlled to be rotationally driven with a low driving force of a low voltage (step S12).

Thus, the power of the opening / closing motor 12f is transmitted to the cable member 12c via the electromagnetic clutch 12e and the drive pulley 12a, and acts to lower the slide door 3 in the opening direction.

If the door lock mechanism 5 is in the unlocked state, the slide door 3 moves in the opening direction, and this movement can be detected by turning on the half door switch 24 (step S13). When the half-door switch 24 is turned on, the processing from step S4 described above is performed, and the slide door 3 is moved in the opening direction.

If the half-door switch 24 is not turned on, it is determined that the door lock mechanism 5 is in the no-lock state, the transistor 11c is controlled to switch the electromagnetic clutch 12e to the disconnected state, and the switch element TR1 is turned off to open and close. The rotation of the motor 12f is stopped (step S14), and the process ends.

(Example 4 of Operation) Next, Example 4 of Operation will be described with reference to the flowchart shown in FIG. The processing procedure shown in FIG. 7 differs from the processing procedure shown in FIG. 6 in that the detection of the movement of the sliding door 3 in the opening direction is performed by using pulse signals φ1, φ2 from the rotary encoder 12g instead of the half-door switch 24.
Is detected from the occurrence and the phase thereof (steps S2a and S13a). Other processing procedures are the same as the processing procedures shown in FIG.

(Fifth Operation Example) Next, a fifth operation example will be described with reference to a flowchart shown in FIG. The processing procedure shown in FIG. 8 is different from the processing procedure shown in FIG.
Instead of driving the slide door 3 low in the opening direction by driving at a low voltage (step S12), the slide door 3 is driven low in the opening direction by controlling the electromagnetic clutch 12e to the half-clutch state. is there.

That is, in step S2a, the detection of the movement of the slide door 3 in the opening direction is detected by the rotary encoder 12g.
If the control signal 11a cannot be detected by the pulse signals .phi.1 and .phi.2, the control circuit 11a drives the transistor 11c to a low voltage so that the electromagnetic clutch 12e is in the half-clutch state (step S11a).

Then, the control circuit 11a controls the switching element T
Turn on R1, then control transistor 11g,
The opening / closing motor 12f is controlled to rotate in the direction in which the slide door 3 moves in the opening direction (step S12).
a). The power of the opening / closing motor 12f is supplied to the cable member 12c via the electromagnetic clutch 12e and the drive pulley 12a.
And act to lower the slide door 3 in the opening direction.

When the opening direction pulse signals φ1 and φ2 are generated (step S13a), the door lock mechanism 5 is not in the locked state and the slide door 3 has moved in the opening direction. 11c is driven at the normal voltage to control the electromagnetic clutch 12e to be in the full clutch state (step S15), and the processing from step S5 described above is performed.

If the opening direction pulse signals φ1 and φ2 are not generated (step S13a), the control circuit 11a determines that the door lock mechanism 5 is in the no-lock state, and controls the transistor 11c to disconnect the electromagnetic clutch 12e. State, and switch element TR1 is turned off to open / close motor 12
The rotation of f is stopped (step S14), and the process ends.

The detection of whether or not the door lock mechanism 5 is in the no-lock state is performed in the same manner as in the first and third operation examples, instead of detecting the generation of the pulse signals φ1 and φ2. It may be performed by detecting the on / off state of.

[0072]

According to the present invention, when the sliding door is driven from the fully closed state to the opening direction by the driving means, if the door lock mechanism is in the no-lock state, the driving by the driving means is stopped. Therefore, it is possible to avoid applying an unnecessary load to the mechanism.

Further, the detection of whether or not the door lock mechanism is in the locked state is performed by operating the release actuator for unlocking the door. Without
In the unlocked state, the operation is performed by detecting that the door lock mechanism is unlocked and the sliding door is moved by the reaction force of the seal rubber, so that the operation can be performed without increasing the number of electrode terminals of the power supply connector.

Further, according to the present invention, when the sliding door is driven by the driving means from the fully closed state to the opening direction, the movement of the sliding door after the release actuator for unlocking the door cannot be detected. However, in consideration of the situation where the vehicle is stopping on a downhill, etc., the sliding door is driven in the opening direction with a low driving force, and it is necessary to drive the sliding door based on the detection result. The locked / unlocked state of the door lock mechanism can be reliably determined, and the door can be driven in the unlocked state and stopped in the locked state.

Therefore, for example, when the vehicle is stopped on a downhill, when the reaction force of the seal rubber is deteriorated due to aging, or when the seal rubber is frozen at low temperatures, the door lock can be securely made. The locked / unlocked state of the mechanism can be detected. In addition, when the seal rubber is frozen, the opening operation is performed at a low drive, so that damage to the seal rubber can be prevented.
