In the figure, a vehicle body 1 includes the above-described slide door drive device 7 and slide door control device 8.
[0027]
The sliding door driving device 7 includes a drive pulley 7a and a reversing pulley 7b. A cable member 7c is wound between the drive pulley 7a and the moving member 7d is fixed to the cable member 7c, and the moving member 7d and the sliding door 2 are hinged. The connection is made via the arm 21.
[0028]
The drive pulley 7a is connected to an open / close motor 7f, which is a drive source, via an electromagnetic clutch 7e. The electromagnetic clutch 7e is configured such that the transmission maintenance force is controlled by the sliding door control device 8.
[0029]
The opening / closing motor 7f is rotationally driven in the opening direction or the closing direction under the control of the sliding door control device 8. When the electromagnetic clutch 7e is turned on, the drive pulley 7a is rotationally driven in the same direction as the opening / closing motor 7f, and moves the cable member 7c in the linear direction between the reverse pulley 7b. As a result, the slide door 2 moves in the front-rear direction.
[0030]
A rotary encoder 7g is linked to the rotation shaft of the drive pulley 7a. The output pulse is input to the pulse signal generator 10 that functions as a movement signal generator, and is input to the slide door controller 8 as two-phase pulse signals φ1 and φ2.

Are two-phase pulse signals φ1 and φ2. In this example, the sliding door 2 is driven in the opening direction when the rotating disk RD rotates to the right.
[0036]
Accordingly, the slide door control device 8 determines the rotational direction of the rotary encoder 7g, that is, the moving direction of the slide door 2 from the phase relationship between these two signals. For example, if the pulse signal φ2 is at a high level when the pulse signal φ1 rises, the open direction is determined (FIG. A), and if the pulse signal φ2 is at a low level, the close direction is determined (FIG. B).
[0037]
Further, the slide door control device 8 determines the position of the slide door 2 by measuring the moving amount of the cable member 7c from the number of pulses of the pulse signals φ1 and φ2. That is, if the number of pulses to the fully open position is counted with the fully closed position of the slide door 2 as an initial value, the counted value represents the position of the moving member 7d, that is, the position of the slide door 2.
[0038]
Returning to FIG. 2, in the slide door 2, the closure motor 22 for tightening the slide door 2 from just before the half latch to the full latch, the closure control unit 23 for controlling the same, and the fact that the slide door 2 has reached the half latch.

It has. The door lock 25 and the striker 39 constitute a door lock mechanism.
[0040]
The electrical element on the vehicle body 1 side and the electrical element on the slide door 2 side are connected to the vehicle body side connector 40 provided in the door opening 3 in a state where the slide door 2 is slightly opened from the fully closed state. This is done by connecting the door side connector 28 provided at the opening end of the door 2. The vehicle body side connector 40 and the door side connector 28 constitute a power supply connector.
[0041]
Further, the closure control unit 23 is connected to the battery 31 and ground on the vehicle body 1 side via both connectors 40 and 28, one end of the half switch 24 is grounded, and the other end is connected to the slide door control device 8 and the closure control unit 23. The release ACT 26 has one end connected to the battery 31 and the other end connected to the slide door control device 8.
[0042]
(Operation example 1)
Next, an operation example 1 of the door opening operation process for moving the slide door 2 to the fully open position will be described with reference to the flowchart shown in FIG.
[0043]
First, when the impact detection sensor 9 does not detect an excessive impact (step S1), the slide door control device 8 determines whether or not a condition for operating the slide door 2 in the opening direction is set (step S2). . That is, it detects that the vehicle body 1 is stopped by the parking signal PK, detects that the automatic opening / closing mode is set by the main switch signal MA, and detects that the opening command is selected by the door opening signal DO. By detecting and detecting that the current position of the slide door 2 is not the fully open position, it is determined that the condition for operating the slide door 2 in the opening direction is ready.
[0044]
When this condition is satisfied, the open / close motor 7f and the drive pulley 7a are mechanically connected by the electromagnetic clutch 7e, and the open / close motor 7f is rotated in the door opening direction to move the slide door 2 in the opening direction ( Step S3).
[0045]
In the meantime, the slide door 2 is moved in the opening direction (step S5) while detecting an overload as to whether or not any foreign matter that suppresses the movement of the slide door 2 is sandwiched. When it is detected that the slide door 2 has reached the fully open position (step S6), the open / close motor 7f is stopped, the mechanical connection between the open / close motor 7f and the drive pulley 7a by the electromagnetic clutch 7e is released (step S7), and processing is performed. Exit.
[0046]
If the operating resistance of the slide door 2 increases due to foreign matter being caught and an overload is detected (step S4), the slide door control device 8 controls the slide door drive device 7 to drive the open / close motor 7f in the reverse direction. Then, the slide door 2 is reversed in the closing direction (step S8).
[0047]
When it is detected that the slide door 2 has reached the fully closed position (step S9), the open / close motor 7f is stopped, and the mechanical connection between the open / close motor 7f and the drive pulley 7a by the electromagnetic clutch 7e is released (step S7). The process is terminated.
[0048]
When the impact detection sensor 9 detects an excessive impact (step S1), it is determined whether or not the above-described conditions for operating the slide door 2 in the opening direction are satisfied (step S11), and the conditions are satisfied. If the open / close motor 7f and the drive pulley 7a are mechanically connected by the electromagnetic clutch 7e of the slide door drive device 7, the open / close motor 7f is rotated in the door opening direction to move the slide door 2 in the opening direction. (Step S12).
[0049]
In the meantime, when the operating resistance of the slide door 2 is increased due to the foreign object being caught and an overload is detected (step S13), the slide door control device 8 controls the opening / closing motor 7f so that the torque increases by a certain amount. Driving force increase control is performed so that the force increases (step S14).
[0050]
If no overload is detected (step S13), the sliding door 2 is moved in the opening direction as it is (step S15). When it is detected that the fully opened position is reached (step S16), the open / close motor 7f is stopped and the electromagnetic clutch The mechanical connection between the opening / closing motor 7f and the drive pulley 7a by 7e is released (step S7), and the process is terminated.
[0051]
As described above, in this operation example 1, when an excessive impact is detected by the impact detection sensor 9, the overload reversal function is canceled, and when an overload is detected, a failure is caused by increasing the power of the drive source. I try to survive. For this reason, there is some deformation in the components of the vehicle body and the automatic opening / closing device, and even if the operating resistance of the slide door 2 increases, the slide door 2 can be prevented from reversing from the opening direction to the closing direction.
[0052]
(Operation example 2)
Next, an operation example 2 of the door opening operation process for moving the slide door 2 to the fully open position will be described with reference to the flowchart shown in FIG. In addition, since the process (steps S1-S9) when the impact detection sensor 9 does not detect an excessive impact is the same as the above-mentioned process, description is abbreviate | omitted.
[0053]
When the impact detection sensor 9 detects an excessive impact (step S1), it is determined whether or not a condition for operating the slide door 2 in the opening direction is satisfied (step S11), and the condition is satisfied. Mechanically connects the opening / closing motor 7f and the drive pulley 7a by the electromagnetic clutch 7e, and rotates the opening / closing motor 7f in the door opening direction to move the slide door 2 in the opening direction (step S12).
[0054]
In the meantime, while detecting overload whether or not some foreign matter that suppresses the movement of the sliding door 2 is caught (step S13), the sliding door 2 is moved in the opening direction (step S21), and the fully opened position is reached. Is detected (step S22), the open / close motor 7f is stopped, the mechanical connection between the open / close motor 7f and the drive pulley 7a by the electromagnetic clutch 7e is released (step S23), and the process is terminated.
[0055]
When the operating resistance of the slide door 2 increases due to foreign matter being caught, and an overload is detected (step S13), the slide door control device 8 controls the opening / closing motor 7f in a direction in which the torque increases by a certain amount, and the power of the drive source Driving force increase control is performed to increase (step S24). This control is repeated for a predetermined time after the overload is detected (step S25).
[0056]
When the vehicle body is greatly deformed and the slide door 2 does not reach the fully open position, after a predetermined time has elapsed (step S25), the open / close motor 7f is stopped and the open / close motor 7f and the drive pulley 7a are mechanically connected by the electromagnetic clutch 7e. Is released to stop the door opening operation (step S26), and the automatic opening / closing mode is canceled to change to the manual opening / closing mode in which manual opening / closing operation is possible (step S27), and the process is terminated.
[0057]
As described above, in this operation example 2, when an excessive impact is detected by the impact detection sensor 9, the overload reversal function is canceled, and when an overload is detected, a failure is caused by increasing the power of the drive source. If you can't get over, change to manual open / close mode. For this reason, there is some deformation in the components of the vehicle body and the automatic opening / closing device, and even if the operating resistance of the slide door 2 increases, the slide door 2 can be prevented from reversing from the opening direction to the closing direction.
[0058]
(Operation example 3)
Next, an operation example 3 of the door opening operation process for moving the slide door 2 to the fully open position will be described with reference to the flowchart shown in FIG. In addition, the process when the impact detection sensor 9 does not detect an excessive impact (steps S1 to S9) and the process when an excessive impact is detected but no overload is detected (steps S21 to S23). Since it is the same as the above-mentioned process, description is abbreviate | omitted.
[0059]
After detecting an excessive impact (step S1), if the operating resistance of the sliding door 2 increases due to foreign object pinching or the like and an overload is detected (step S13), the sliding door control device 8 causes the opening / closing motor 7f to have a constant torque. The driving force is increased and controlled so that the driving force is increased (step S24). This control is repeated for a predetermined time after the overload is detected (step S25).
[0060]
When the vehicle body is greatly deformed and the slide door 2 does not reach the fully open position, after a predetermined time has elapsed (step S25), the open / close motor 7f is stopped and the open / close motor 7f and the drive pulley 7a are mechanically connected by the electromagnetic clutch 7e. Is released to stop the door opening operation (step S26), and the automatic opening / closing mode is canceled to set the manual opening / closing mode to allow manual opening / closing operation (step S27).
[0061]
Thereafter, the slide door control device 8 detects that the two-phase pulse signals φ1 and φ2 are generated from the pulse signal generator 10 (step S28), and the vehicle body 1 is stopped in the downward direction on the sloping ground. When it is detected that 2 has started to move in the closing direction due to natural fall, the mechanical connection between the opening / closing motor 7f and the drive pulley 7a is set to a half-clutch state so that the sliding door 2 does not fall in the closing direction (step S29). ), The process is terminated. However, it is temporarily held with a holding force that can be manually opened and closed.
[0062]
When the two-phase pulse signals φ1 and φ2 are not generated from the pulse signal generator 10 (step S28), it is determined that the vehicle body 1 is stopped on a flat ground, and the process is immediately terminated.
[0063]
Instead of detecting the generation of the pulse signals φ1 and φ2 from the pulse signal generator 10, the sliding door control device 8 detects that the vehicle body 1 is stopped on the inclined ground in the downward direction by the inclination sensor 38. Thus, the sliding door 2 may be temporarily held in a half-clutch state.
[0064]
As described above, in this operation example 3, when an excessive impact is detected by the impact detection sensor 9, the overload reversal function is canceled, and when an overload is detected, a failure is caused by increasing the power of the drive source. If you can't get over, change to manual open / close mode, and then you can manually open and close when the sliding door starts moving in the closing direction or when the car body is stopped down on the slope. A half-clutch state is established with a certain holding force.
[0065]
For this reason, there is some deformation in the components of the vehicle body and the automatic opening / closing device, and even if the operating resistance of the slide door 2 increases, the slide door 2 can be prevented from reversing from the opening direction to the closing direction.
[0066]
【The invention's effect】
According to the first aspect of the present invention, when an excessive impact is detected by the impact detection sensor, the overload reversal function is canceled, and when the overload is detected, the power of the drive source is increased to overcome the obstacle. Therefore, even if the operating resistance of the moving sliding door increases, the advantageous effect that the sliding door does not reversely move is obtained.
[0067]
According to the second aspect of the present invention, when an excessive impact is detected by the impact detection sensor and the operating resistance increases while the slide door is moving in the opening direction, the driving force of the driving source is increased in the opening direction. Since it did in this way, even if the operating resistance of the sliding door moving in the opening direction increases, the advantageous effect that the sliding door does not reversely move in the closing direction can be obtained.
[0068]
According to the third aspect of the present invention, when an excessive impact is detected by the impact detection sensor, the overload reversal function is canceled, and when an overload is detected, the driving source power is increased to prevent the failure. Since the vehicle is overridden, and when it cannot be overridden, the mode is changed to the manual opening / closing mode. Therefore, even if the operating resistance of the moving sliding door increases, an advantageous effect that the sliding door does not reversely move is obtained.
[0069]
According to the fourth aspect of the present invention, when an excessive impact is detected by the impact detection sensor, the overload reversal function is canceled, and when an overload is detected, the failure of the drive source is increased by increasing the power of the drive source. If the sliding door starts to move in the closing direction in that state, change it to the manual opening / closing mode. Therefore, even if the operating resistance of the moving sliding door increases, an advantageous effect that the sliding door does not reversely move from the opening direction to the closing direction can be obtained.
[0070]
According to the fifth aspect of the present invention, when an excessive impact is detected by the impact detection sensor, the overload reversal function is canceled, and when the overload is detected, the power of the drive source is increased to overcome the obstacle. If you can't ride, change to manual open / close mode, and when the car is stopped in a downward direction on a sloping ground, it will move to the half-clutch state with a holding force that allows manual open / close operation. Even if the operating resistance of the sliding door increases, an advantageous effect that the sliding door does not reversely move from the opening direction to the closing direction can be obtained.
