According to the electric sliding door device of the fourth aspect, when the opening / closing speed of the sliding door is lower than the threshold value, the sliding door is turned over assuming that entrapment has occurred. Further, a threshold value lower than the threshold value is set for the opening / closing speed of the slide door at the time of cranking the engine so that the reversing operation is not performed even if the speed is reduced due to a decrease in the power supply voltage. Furthermore, when the voltage generated by the alternator turns positive, it can be detected that cranking has ended and the engine has started. Therefore, at the time of cranking, even if the power supply voltage decreases, the electric door opening and closing operation can be ensured. Further, it is possible to directly detect the end of cranking without detecting an increase in the speed of the sliding door as in the related art.

According to the electric sliding door device of the present invention, when the half-latch switch or the full-open switch is turned on and the full closing or the full opening of the sliding door is detected, the electromagnetic engagement clutch and the driving motor are turned off. Then, the drive motor is reversely driven for a predetermined time. Therefore, the engagement of the electromagnetic engagement clutch can be reliably released.

When the process starts, it is first determined in step S10 whether the operation switch 3 has been operated to open the door. If the door opening operation has been performed, it is subsequently determined whether or not the operating condition is satisfied.
The operating condition is that the main switch MSW is on, the power supply voltage is 11 V or more, and the vehicle speed is 3 when the engine is on.

The cycle of the pulse generated by the first speed sensor 10a or the second speed sensor 10b is detected according to the moving speed of the sliding door in the opening direction, and it is determined based on this the first overload detection level. For example, when a person or an object is caught in the sliding door and an overload occurs and the first overload detection level is determined, it is determined whether or not the engine is cranking. The cycle of the pulse generated by the sensor 10a or the second speed sensor 10b is detected, and it is determined whether or not the pulse is at the second overload detection level (Steps S36 to S40). If it is not the first overload detection level in step S36, the drive motor 20 is stopped by turning on the fully open switch 12 (step S42).

The slide door is fully closed by operating the closer (steps S50 to S58). Further, even if the position of the slide door is out of the range of 600 mm from the fully closed position, if the half latch switch 26a is ON, the closer is operated to fully close the slide door. If the operation switch 3 is operated again in step S48, the drive motor 20 is stopped and the alarm buzzer is sounded for 0.5 seconds. It is determined whether or not the operation switch 3 has been operated again while the alarm buzzer is sounding. If the operation switch 3 has not been operated again, the process is terminated (steps S60 to S62). If the operation has been performed again, it is determined in step S64 whether or not the door opening operation has been performed. If the door opening operation has been performed, the door opening processing in step S34 and subsequent steps is executed. Execute the process. Note that the second overload detection level is set to a level lower than the first overload detection level.

If the half-latch switch 26a is off at step S54, it is determined whether or not it is at the first overload detection level, and if it is during engine cranking, it is determined whether it is at the second overload detection level. (Steps S66 to S7
0). If the engine is not cranking at the first overload detection level, or if the engine is at the second overload detection level during engine cranking, the drive motor 20 is stopped in step S72 and an alarm buzzer is sounded for two seconds. If it is not the first overload detection level in step S66, and if it is not the second overload detection level in step S70, the process returns to step S48.

On the other hand, if the operation switch 3 is not operated to open the door in step S10, the process proceeds to step S80 shown in FIG. 4, and it is determined whether or not the operation switch 3 is operated to close the door. If the operation switch 3 has been operated to close the door, the steps S12 to S98 are repeated at the steps S12 to S98.
The operating conditions are determined by the same processing as in steps # 28 to # 28. If the operation condition is satisfied, the process proceeds to step S100,
The drive motor 20 rotates in the door closing direction. When the position of the slide door is within a range of 600 mm from the fully closed position, the alarm buzzer sounds intermittently, and the drive motor 20 and the alarm buzzer are stopped by turning on the half-latch switch 26a, and the closer is operated to close the slide door. Fully close. Also, the position of the sliding door is 600m from the fully closed position.
If the half-latch switch 26a is on even if it is out of the range of m, the closer is operated to fully close the slide door (steps S102 to S110). If the half-latch switch 26a is off in step S106, it is determined whether or not it is at the first overload detection level, and if it is during engine cranking, it is determined whether or not it is at the second overload detection level (step S112). To S116).

When the engine is not being cranked at the first overload detection level,
If it is the overload detection level, the process proceeds to step S shown in FIG.
Proceeding to 118, the drive motor 20 is reversed to automatically move the slide door in the opening direction. At this time, operation switch 3
It is determined whether or not has been operated again (step S12)
0). If the operation has not been performed again, it is determined whether or not the engine is at the first overload detection level, and if the engine is cranking, it is determined whether or not the engine is at the second overload detection level (step S12).
2 to S126). If the engine is not being cranked at the first overload detection level, or if the engine is at the second overload detection level during engine cranking, the process proceeds to step S4.
6 and the following processing is executed.

If it is not the first overload detection level in step S122, the drive motor 20 is stopped by turning on the full-open switch 12, and the alarm buzzer sounds for 2 seconds (steps S128 to S130). Step S1 above
When the operation switch 3 is operated again at 20, the drive motor 20 is stopped and at the same time an alarm buzzer sounds for 0.5 seconds,
It is determined whether or not the operation switch 3 has been operated again while the alarm buzzer is sounding. If the operation switch 3 has not been operated again, the process is terminated (steps S132 to S134). When the operation is performed again, it is determined whether or not the operation is the door closing operation. If the operation is the door closing operation, the door closing processing of step S100 and subsequent steps is executed. I do.

If the operation switch 3 has not been operated to close the door in step S80, step S14 shown in FIG.
Go to 0. Here, the sliding door courtesy switch 13
Is switched from off to on and the half-latch switch 26a is switched from on to off, and it is determined that the slide door in the fully closed state has been manually opened to the predetermined position (steps S140 to S142), and steps S144 to S16.
At 0, the operating condition is determined by the same processing as in steps S12 to S28. If the operating conditions are met,
The drive motor 20 rotates in the door opening direction to automatically open the slide door. At this time, as soon as there is an input from the operation switch 3, the drive motor 20 is stopped (step S162).
To S166). If there is no input from the operation switch 3, the processing from step S122 is executed.

If the slide door courtesy switch 13 is not switched from off to on in step S140, the process proceeds to step S170 shown in FIG. Here, the fully open switch 12 is turned off from on, and the first speed sensor 10a is turned off.
And based on the pulse generated by the second speed sensor 10b, the closing direction movement of the sliding door is detected,
When it is determined that the slide door in the fully open state has been manually closed to the predetermined position by the count signal when the number of pulses counted by the logic circuit 2 is three or more (steps S170 to S172), steps S174 to S174 are performed.
In S190, the operating condition is determined by the same processing as in steps S12 to S28. If the operating condition is satisfied, the drive motor 20 is rotated in the door closing direction to automatically close the slide door. At this time, when there is an input from the operation switch 3, the drive motor 20 is immediately stopped (steps S192 to S196).

If there is no input from the operation switch 3 in step S194, the process proceeds to step S198 shown in FIG. Here, the position of the slide door is 600 from the fully closed position.
mm, the alarm buzzer sounds intermittently, and the half-latch switch 26a is turned on to stop the drive motor 20 and the alarm buzzer, operate the closer, and fully close the slide door (steps S198 to S2).
06). In addition, the position of the sliding door is 60 degrees from the fully closed position.
Even if it is outside the range of 0 mm, the half-latch switch 26
When a is on, the closer is operated to fully close the slide door. If the half-latch switch 26a is off in step S202, it is determined whether or not the engine is at the first overload detection level, and if the engine is cranking, it is determined whether or not it is at the second overload detection level (step S208). ~ S
214). If the engine is not cranking at the first overload detection level, or if the engine is at the second overload detection level during engine cranking, the process proceeds to step S214, in which the drive motor 20 is reversed to move the slide door in the opening direction. . Then, the process from step S122 is performed. If it is not the first overload detection level, or if it is not the second overload detection level during engine cranking, the processing from step S194 is executed. If the fully open switch 12 does not switch from on to off in step S170, the drive motor 20 does not operate (step S171). If the operator releases the operation switch 3 during the door opening and closing operations by the operation switch 3, the drive motor 20 immediately stops (step S171).

In the opening / closing process, if the power supply voltage drops to less than 11 V during the opening operation of the slide door, the voltage drop is ignored and the door opening process is continued. In addition, during the closing operation of the sliding door, the power supply voltage drops to less than 11 V, the vehicle speed exceeds 3 km / h, the parking brake switch, the shift position “P” range switch, and all the stop lamp switches are turned off. However, the door closing process is continued. Thereby, safety during opening and closing operation of the slide door is ensured.

As described above, when the slide door in the fully closed state is manually opened to the position where the slide door courtesy switch 13 is switched from off to on and the half latch switch 26a is switched from on to off, the slide door is automatically opened thereafter. Be teased. Further, the fully opened slide door is manually closed from the ON state to the OFF state to the position where three or more pulses generated by the first speed sensor 10a or the second speed sensor 10b are counted by the logic circuit 2. Then, the slide door is automatically closed thereafter. Therefore, the slide door in the fully closed state or the fully open state can be automatically opened and closed without depending on the operation of the operation switch 3.

The timing charts of FIGS. 9A and 9B show the operation during the automatic opening and closing operation (hereinafter referred to as assist operation) after the sliding door is manually opened and closed from the fully closed position or the fully opened position to a predetermined position. 3 schematically shows a process in which the operation state of a slide door can be changed by a switch 3. As shown in FIG. 9A, when a signal for opening or closing the operation switch 3 is input to the logic circuit 2 during the assist operation, the alarm buzzer sounds for T1 seconds and the output to the drive motor 20 is output. The sliding door stops and stops. Thereafter, when the operation switch 3 is again operated to open or close the door, the slide door is opened or closed according to the operation signal. Further, as shown in FIG. 9B, while the alarm buzzer is sounding, that is, before the elapse of T1 seconds from the operation of the operation switch 3 during the assist operation, the operation switch 3 is operated to open or close the door again. Then, the slide door opens or closes in response to the opening / closing operation signal immediately before the lapse of T1 seconds.

As described above, the operating slide door can be stopped or inverted in response to the opening / closing operation signal of the operation switch 3 during the assist operation. Therefore, safety during the assist operation of the slide door can be improved.

FIGS. 10A and 10B show steps S50 in FIG. 3, step S102 in FIG. 4, and step S50 in FIG.
FIG. 3 is a schematic timing chart illustrating slide door position detection in 198 and slide door overload detection in steps S36 and S40 in FIG. The position detection and the overload detection are performed based on pulses generated by the first speed sensor 10a and the second speed sensor 10b in response to the opening / closing speed of the sliding door. As shown in FIG. 10A), the entire stroke of the slide door from fully closed to fully opened is determined by the first speed sensor 10a and the second speed sensor 10b.
Is defined by the number N of pulses in which the error occurs. Then, the logic circuit 2 calculates the position of the slide door based on the number of pulses counted in response to the opening and closing operation of the slide door.
Further, the opening / closing speed of the sliding door is calculated based on the pulse counting cycle.

As shown in FIG. 10 (b), when the opening / closing speed becomes slow and the count cycle is extended, it is determined that an overload has occurred due to pinching of the slide door or the like.
A predetermined threshold value is set for this counting cycle, and is set as a first overload detection level. The opening / closing operation direction of the sliding door is detected based on the pulses generated by the first speed sensor 10a and the second speed sensor 10b in which the phases of the generated pulses are shifted by １ ／ pitch.

Since the position of the sliding door can be detected as described above, the drive motor 2 can be used for closing and opening.
When the power of the slide door is increased or when the operation position of the slide door is within a range of 600 mm from the fully closed position, it is possible to perform an appropriate opening / closing control such as intermittently sounding an alarm buzzer. Further, by detecting the overload based on the first overload detection level, it becomes possible to perform control such as stopping the slide door where the entrapment has occurred and then inverting the slide door. further,
Since the position of the sliding door and the opening / closing operation direction can be detected, the above-described control is possible even when the sliding door is electrically opened / closed by the operation switch 3 during opening / closing.

FIG. 11 is a timing chart showing the contents of processing when the engine is started during the electric door opening / closing operation. If the engine is started while the sliding door is being driven to open and close electrically, the power supply voltage drops sharply due to cranking. For this reason, the opening / closing speed of the slide door becomes slow, and it is determined that the jamming has occurred based on the first overload detection level. Therefore, during cranking, the second overload detection level, which is a threshold lower than the first overload detection level, is set (step S40 in FIG. 2 and step S70 in FIG. 3). etc).
Since the second overload detection level is applied only during cranking, it is necessary to detect the start and end of cranking.

Conventionally, the start of cranking is detected when the rate of decrease of the power supply voltage exceeds a specified value, and the end of cranking is detected when the opening / closing speed of the slide door increases. According to this, the end of cranking can be detected only as the final sliding door speed. For this reason,
If the speed of the slide door fluctuates due to disturbance, erroneous detection may occur. Further, an arithmetic processing by the logic circuit 2 for detecting the increase in the speed of the sliding door is required. Therefore, as shown in FIG.
Logic circuit 2 to which alternator L terminal signal circuit 6 is connected
(CHG-) terminal of this embodiment detects when the voltage generated by the alternator changes from 0 to + BV. Accordingly, the end of cranking can be reliably detected without erroneous detection, and the arithmetic processing for detection by the logic circuit 2 becomes unnecessary.

FIG. 12 shows the electromagnetic clutch 1 described above.
9 is a perspective view of a rotor 81 and an armature 91. FIG. When the electromagnetic coil is energized, the armature 91 is attracted and moves on the rotating shaft 92, and the arc-shaped long hole 82 of the rotor 81 is moved.
The cylindrical projection 93 of the armature 91 fits into the armature 91 and is pressed against the lower surface of the disk portion 83 of the rotor 81. When the drive motor 20 is driven, the rotor 81 rotates, and the end of the arc-shaped long hole 82 and the columnar projection 93 come into contact with each other to engage with each other, and the driving force is transmitted to open and close the slide door. . If the slide door stops at the opening / closing end or in the middle of opening / closing and the power is turned off, the power supply to the electromagnetic coil is cut off. At this time, if the arc-shaped long hole 82 of the rotor 81 and the columnar projection 93 of the armature 91 remain engaged, manual opening and closing cannot be performed.

For this reason, as shown in the timing chart of FIG. 13, after the operation is stopped, the open relay circuit 16 or the close relay circuit 18 is closed for T2 seconds, and the drive motor 20 is driven in reverse. As a result, the engagement between the arc-shaped long hole 82 and the cylindrical projection 93 is forcibly released.
Therefore, it is possible to mechanically disengage the clutch that cannot be disengaged only by cutting off the power supply to the electromagnetic coil, and it is not necessary to provide a special disengagement mechanism.
