The power window motor (denoted by 8) is connected. The controller 28 corresponds to the moving direction determination means and the control means.

In this embodiment, the operation switch 25
The controller 28 discriminates the state of the roof 21 based on the detection signal of each micro switch by the operation of, and operates each mechanism as shown in Table 1.

[0019]

[Table 1]

That is, when the roof 21 in the mounted state (see FIG. 6a) is housed in the roof housing portion 16a of the trunk lid 16, first, the operating lever 32 of the lock mechanism 32 is first housed.
By operating a, the connection between the roof 21, the front cross member 13 and the roll bar 15 is released, and thereafter, the OPEN / CLOSE position of the operation switch 25 is pushed. Then, the controller 28 uses the micro switches 35, 5
Based on the detection signals of 0, 51, 52, 53, 54, the operating direction of the roof 21 is discriminated and the mechanisms 29, 30, 31, 34, 38 etc. are driven to open the roof 21.

As a result, first, if the door glass of each of the doors 26 and 27 is closed, the power window motor is energized to lower the door glass and the trunk lock mechanism 30.
The actuator is energized to unlock the trunk lock mechanism 30, and then the electric motor of the lifting mechanism 29 is energized to raise the trunk lid 16 to a predetermined raised position (see FIG. 6b).

After that, when the trunk lid 16 is raised to a predetermined raised position, the actuator of the tilt mechanism 34 is energized to lift the rear end of the roof 21 (see FIG. 6c). Then, the electric motor of the slide mechanism 31 is energized and the engaging pin is inserted into the rear end of the roof 21 (see FIG. 6d). Here, the continuous operation by one operation of the operation switch 25 ends. Then, the driver or the like operates the operation lever of the coupling mechanism 33 to operate the engagement pin and the roof 21.
And are connected.

Next, the driver or the like opens the operation switch 25.
When the / CLOSE position is pushed again, the controller 28 determines the moving direction of the roof 21 based on the detection signal of each micro switch and drives each mechanism. For this reason, the slide mechanism 31 retracts the engaging pin into the trunk lid 16 to accommodate the trunk lid 16 in the roof accommodating portion 16a integrally with the engaging pin, and thereafter the tilt mechanism 34 returns to its original state. (See Figure 6e). Then, after this, the trunk lid 16 is moved up and down while the roof 21 is housed.
And the trunk lock device 30 locks the trunk lid 16 to the vehicle body 20 when the vehicle reaches a predetermined lowered position (see FIG. 6f). In addition, the roof 2
When driving No. 1 again, the moving direction of the roof 21 by the previous operation may be stored and driven in this stored moving direction.

The roof 21 (see FIG. 6f) housed in the trunk lid 16 is attached to the front cross member 13.
Also when mounted between the roll bar 15 and the roll bar 15, when the open / close position of the operation switch 25 is pushed, the microcomputer of the controller 28 controls the operation of each mechanism based on the detection signal of each micro switch.

Therefore, contrary to the above case, first, if the glass of each door 26, 27 is in the closed state, the glass is lowered, the trunk lock mechanism 30 is unlocked, and then the elevating mechanism. The trunk lid 16 is raised by 29 (see FIG. 6e). Then, after this, the slide mechanism 31
Pushes out the engaging pin and sends out the roof 21 (Fig. 6d).
Also, the tilt mechanism 34 lifts the rear end of the roof 21 (see FIG. 6c). Here, 1 of the operation switch 25
After the operation is completed, the driver or the like manually operates the connecting mechanism 33 with the operation lever to disengage the engaging pin from the roof 21.

Next, the driver or the like opens the operation switch 25.
When the / CLOSE position is pushed again, the controller 28 determines the moving direction from the detection signal of each micro switch. Therefore, the tilt mechanism 34 operates to lift the rear end of the roof 21, and subsequently, the slide mechanism 31 stores the engagement pin in the trunk lid 16. And roof 2
When 1 is positioned at a predetermined position between the front cross member 13 and the roll bar 15, the tilt mechanism 34 returns to its original state (see FIG. 6b).

After that, the trunk lid 16 is lifted by the lifting mechanism 2
It is lowered by 9 and when it reaches a predetermined position, it is locked by the trunk lock mechanism 30 (see FIG. 6a). And
The driver or the like manually operates the lock mechanism 32 to engage the roof 21 with the front cross member 13 and the roll bar 15.

On the other hand, even when the roof 21 is stopped at an intermediate position, when the open / close position of the operation switch 25 is pushed, the controller 28 stops the roof 21 based on the detection signal of the micro switch or the stored data. Each mechanism is driven to move in the direction, that is, to continue the pre-operation. Therefore, even if the roof 21 stops at an intermediate position, the roof 21 can be reliably moved in the direction desired by the driver or the like.

On the contrary, while the roof 21 is moving,
When the driver or the like presses the reverse position of the operation switch 25, the roof 21 moves in the reverse direction as shown in the lower part of Table 1. Therefore, the roof 21 can be moved in a desired direction, and the degree of freedom in operation does not decrease.

Further, the controller 28 is operated as shown in Table 2 when the stored data is lost, and the roof 21 is closed in the middle.

[0031]

[Table 2]

In this embodiment, it is also possible to provide a rotation detector such as an encoder on the electric motor of each mechanism and to detect the position by the encoder and the micro switch. Then, for example, when the encoder is provided on the electric motor of the lifting mechanism 29, the position detection and the failure diagnosis of the trunk lid 16 are performed by performing the processing shown in FIG.

In the process shown in FIG. 5, it is judged based on the output of the microswitch 52 whether or not the trunk lid 16 has reached a predetermined raised or lowered position (step 1). Is turned on) and the timer starts counting (step 2). Then, if the encoder stops the pulse output within a predetermined time, for example, 500 msec, the power supply to the electric motor is stopped after a predetermined time (for example, 100 msec) has elapsed (steps 3, 4,).
5) Also, if the encoder does not stop the pulse output within a predetermined time, it is determined that there is a failure, the power supply to the motor is stopped, and the failure is displayed (steps 5, 6, 7).

Further, in this embodiment, the state of the roof 21 is judged by the microcomputer, but it is also possible to store the moving direction of the roof 21 and move it in the previous operating direction. It is also possible to use a self-holding circuit or the like without a relay.
