DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a lift roof which is lifted and lowered with respect to a main body roof of a vehicle separately from the main body roof of the vehicle. And a roof elevating device for a vehicle configured such that an occupant's living space is formed therebetween.

[0002]

2. Description of the Related Art Heretofore, there has been known a main body roof of a vehicle in which an elevating roof is provided separately from the main body roof so as to be able to move up and down. The elevator roof normally covers the main body roof and constitutes a part of the roof of the vehicle. When necessary, the elevator roof is raised to form an occupant's living space between the body roof and the elevator roof. You can do it. For example, a bellows-like curtain member is attached in advance between the elevating roof and the main body roof, and when the elevating roof is raised, the curtain member also rises, and the living space is shut off from the outside world. ing. If you lay a bed in a living space shielded from the outside like this,
You can use that space as a temporary bedroom,
Alternatively, it can be used as a luggage storage area.

[0003] However, such a lifting and lowering of the lifting roof can be performed manually, but in general, since it is performed by using a motor, regardless of whether an occupant is on the main body roof or not. For example, if it is possible to freely move up and down only by operating the operation switch disposed on the vehicle compartment side under the main body roof, the occupant on the vehicle room side can operate the operation switch without noticing that there is an occupant on the main body roof. It may happen that the operation is performed on the descending side. When this happens, the occupants on the main body roof may be surprised to fall unexpectedly, and beds etc. laid on the main body roof may be pinched between the elevating roof and the main body roof, possibly leading to damage. is there. Therefore, there is a need for measures to prevent such erroneous operation and to prevent unexpected lowering.

Japanese Patent Laid-Open Publication No. 3-253421 discloses a sunroof whose main body roof partially opens and closes. When the sunroof is closed, an object is sandwiched between the sunroof opening of the sunroof and the sunroof. Japanese Patent Laid-Open No. 60-107418 discloses a technique for preventing the sunroof from closing any more if both the closing instruction switch and the automatic instruction switch are not turned ON. In the technique disclosed in Japanese Utility Model Laid-Open Publication No. 3-64820, a single switch is used, and the sunroof is lowered only when the single switch is continuously turned on for a predetermined time. And the like. Therefore, it is conceivable to apply these techniques to the above-described measures for preventing the roof from unexpectedly lowering.

[0005]

However, the technique described in the first aspect allows the sunroof to be closed to a certain extent. If such an elevating operation is allowed to some extent, the elevating roof may be unexpectedly lowered due to a malfunction and a foreign object or the like may be pinched, and the inconvenience due to the erroneous operation cannot be eliminated.

Further, the second technique is directed to a sunroof whose condition can be easily understood from the passenger compartment even if the malfunction is prevented by driving only two switches at the same time. Therefore, even if this technology is applied to an elevating roof where it is difficult to grasp the situation of the living space on the main body roof from the cabin side below the main body roof, erroneous operation without noticing the presence of the occupant on the main body roof Can happen.

[0007] Further, even if the third technique is to prevent a malfunction under the condition that a single switch is continuously operated for a predetermined time, the situation can be easily grasped from the passenger compartment side in the same manner as described above. Since this technology is intended for a sunroof, even if this technology is applied to an elevating roof in which it is difficult to grasp the state of the living space on the main body roof, an erroneous operation may eventually occur.

When the lift roof 53 is fully lifted, the state shown in FIG. 21 is reached, and the living space formed between the lift roof 53 and the main body roof 52 is shut off from the outside. In this case, in FIG.
A portion 88A, which is surrounded by the main body roof 3 and the body roof side mounting portion 84 and the bending line 85, is located between the lift roof 53 and the body roof 52 on the longitudinal side of the vehicle 1, and the lift roof side mounting portion 86 and the body A portion 88B surrounded by the roof-side mounting portion 87 and the bending line 85 is located between the lifting roof 53 and the main body roof 52 at the front end of the lifting roof 53.

A window 89 made of a transparent member is formed in a portion 88B of the tent member 81 to secure a front view. Further, a fastener member 90 is provided over substantially the entire length of the tent member 81 above the window 89, and the tent member 81 can be opened as required.

FIG. 22 shows a state in which a bed 91 is laid on the opening 59 of the main body roof 52. Bed 91
The elevating roof 53 is raised with respect to the main body roof 52, and is laid on the opening 59 after being brought into a fully opened state. Or
It is laid on the opening 59 from the beginning. The bed 91 is desirably divided into three parts or folded in three steps.

Next, referring to FIG.
The opening / closing state of the elevating roof 53 according to the movement of No. 6 will be described.

When it is not necessary to open the elevating roof 53 while the vehicle is running, the roller 63 attached to the lower end of the link member 56 is located near the rear end of the rail portion 64 (ie, the rearmost side of the vehicle 1). At the position X1, and in this state,
As shown by a chain line in FIG. 23, the link member 56 is in a lying state, and the lifting roof 53 is also closed with respect to the main body roof 52.

When the vehicle 1 stops and it becomes necessary to open the lift roof 53, the motor 69 is rotated forward. The forward rotation of the motor 69 causes the rod member 72 to start moving forward of the vehicle. Since the link member 56 is movably connected to the rod member 72 at the lower end thereof, the roller 63 starts moving forward along the rail 64 by the movement of the rod member 72 toward the front of the vehicle. The roller 67 supported at an arbitrary point of the link member 56 also starts to rise along the rail 61 toward the front of the vehicle. As the two rollers 63 and 67 roll, the link member 56 gradually rises from the initial lying state (shown by a chain line in FIG. 23) in the direction of arrow Y1. .

Since the rail 61 is inclined upward toward the front of the vehicle, the roller 63 at the lower end of the link member 56 is pushed by the rod member 72 and moves toward the front of the vehicle.
The vertical distance between the direction in which the rod member 72 exerts a force on the roller 63 (that is, the direction in which the rail 64 extends) and the roller 67 increases. The moment M about the roller 67 for raising the link member 56 in the direction of the arrow Y1 is expressed by the following equation. Moment M = (biasing force F exerted on roller 63 by motor 69) × (vertical distance L between roller 67 and roller 63) Although biasing force F exerted on motor 63 by motor 69 is constant, roller 67 and roller 63 The vertical distance L between the link member 63 and the link member 63 increases as the link member 56 rises in the direction of arrow Y1. That is, as the roller 63 is pushed by the rod member 72 and moves forward of the vehicle, the link member 56 is moved to the arrow Y1.
Is increased, and the initial rising operation of the link member 56 is easily performed.

Thereafter, when the rod member 72 keeps pushing the roller 63, and the roller 63 reaches the position X2 of the guide rail 52, which is closest to the front of the vehicle, the roller 67 reaches the uppermost end of the guide rail 61. Then, the motor 69 stops operating. During this time, the lifting roof 53 continues to rise in the direction of arrow Y1, and when the roller 63 reaches the position X2,
The main body roof 52 is in a fully opened state (a state shown by a solid line in FIG. 23).

When the roller 63 is at the position X1, the damper member 58 is in a lying state as shown in FIG. Therefore, the urging force of the damper member 58 acts only slightly on the lifting roof 53. As the roller 67 moves up the rail 61, the damper member 58 also gradually moves from the lying state to the upright state, and the urging force exerted on the lifting roof 53 increases. That is, the damper member 58 starts exerting a biasing force on the lift roof 53 from the time when the roller 67 reaches a certain point on the rail 61, and promotes the lift of the lift roof 53.

That is, the lifting roof 53 performs an initial rising operation only by the action of the moment M at the beginning, that is, while the damper member 58 is not operated much. In addition, the upright operation is performed by receiving the urging force of the damper member 58. As described above, the lifting roof 53 is effectively subjected to the action of the moment M and the damper member 58, and
Rise against two.

When closing the elevating roof 53, that is, when lowering the elevating roof 53 toward the main body roof 52, the motor 69 is reversed. As a result, the rod member 72 moves to the rear of the vehicle, the roller 63 starts rolling toward the rear of the vehicle along the rail 64, and the roller 67 moves to the rail 61.
Descend along. As the rollers 63 and 67 roll, the link member 56 descends in the direction of arrow Y2, and when the roller 63 reaches the initial position X1, the lifting roof 53 is moved.
Is in a closed state with respect to the main body roof 52 (a state indicated by a chain line in FIG. 22). Third Embodiment The third embodiment is based on the premise that an elevating drive structure for elevating the elevating roof 53 with respect to the main body roof 52 in the above-described second embodiment is provided. This is a more specific example of the drive control for 69 from the viewpoint of preventing erroneous operation.

As shown in FIG. 24, the lifting device according to the third embodiment includes a control means 1 for controlling the lifting and lowering of the lifting roof 53.
00 on the input side of the control means 100.
An ignition switch IG, a brake switch BR serving as a parking brake detecting unit, a vehicle speed sensor 111 forming a part of a stop state detecting unit, and an operation switch (first operation switch) 112 serving as a lifting / lowering operation unit
And the four limit switches 113, 114, 115,
116 and a power cut switch 117 (second operation switch) as erroneous operation prevention means. On the other hand, the output side of the control means 100 is provided with a pair of motors 6.
9, 69, a warning buzzer 121, and a warning lamp 122
And an electromagnetic fuel cut valve 123 are connected.

The ignition switch IG detects ON / OFF of an ignition key, the brake switch BR detects an operation state of a parking brake, and is turned ON. Is for detecting the speed of the vehicle.

The operation switch 112 is constituted by a seesaw-type switch as in the second embodiment. When the operation switch 112 is pushed to the OPEN position, the operation switch 112 generates a signal for rotating the motors 69 to the side for moving the elevating roof 53 up and down. CL
When the OSE position is pressed, a signal for rotating each of the motors 69 is issued to the control means 100 on the side of lowering the motors 69 for lowering the elevating roof 53.

The above four limit switches 113 and 11
4, 115, 116, the first limit switch 113
Is the roller 6 when the lift roof 53 is in the fully opened and lifted state.
Rail 6 at a position corresponding to position X2 of 3 (see FIG. 18)
When the rollers 63 are moved along the rails 64 by the driving of the motors 69 to reach the position X2, a switch member (not shown) provided on the bracket 56a of the link member 56 is connected to the switch member. By contacting and operating the first limit switch 113, it is detected that the elevating roof 53 is at the fully open ascent position. Hereinafter, based on the same principle as that of the first limit switch 113, the second limit switch 114 is disposed on the rail 64 at a position corresponding to the position of the roller 63 when the lift roof 53 is in the intermediate stop state. Is detected to be in the intermediate stop position, and the third limit switch 115 moves the rail 64 at a position corresponding to the position X1 of the roller 63 on the right and left guide rails 60 when the elevating roof 53 is fully closed and lowered. And the fourth limit switch 116 is connected to the left and right guide rails 60 when the lift roof 53 is in the fully closed and lowered state. The roller 63 is disposed on the rail 64 at a position corresponding to the position X1 of the roller 63 so as to detect that the lifting roof is at the fully closed and lowered position. That is, the detection that the elevating roof 53 is at the fully closed lowering position is made by the two limit switches 115,
The above-mentioned detection is performed reliably even at the time of abnormality such as a failure of switches.

The power cut switch 117 is constituted by an electric switch of an auto return type.
The contact is normally in an OFF state in which the contact is open, the contact is closed and turned ON only when an operation force is applied, and the operation automatically returns to the OFF state when the operation force is removed. That is, the power is normally cut off and the power is cut off, and an ON signal is issued to the control means 100 only when an ON operation is performed.

The warning buzzer 121 is sounded according to the state of the roof 53 and the state of the vehicle to give an auditory warning to the operator and the occupant.
By changing the sounding cycle of the buzzer, the recognizability to the operator or the like is reduced. In addition, the warning lamp 122 is disposed at a position near the operation switch 112 or the like, and gives a visual warning to the operator or the like by blinking or the like.

Further, the fuel cut valve 123
Is connected to the control means 100 via a fuel cut relay (not shown), the fuel cut relay is normally turned off, and the fuel cut valve 123 is opened, that is, the fuel supply state is set. When the fuel cut relay is turned on, the fuel cut valve 123 is closed and the supply of fuel to the engine is shut off.

The arrangement of the pair of motors 69, 69, the structure for transmitting the lifting force of the lifting roof 53 by the motors 69, and the like are the same as those in the second embodiment, and a description thereof will be omitted.

The control means 100 includes an ascending drive control section 101 for controlling the ascent and descent of the ascending and descending roof 53,
A lowering drive controller 102 for controlling the lowering operation of the elevating roof 53, a warning buzzer controller 103 for controlling a sounding operation of a warning buzzer 121, a warning lamp controller 104 for controlling a lighting operation of a warning lamp 122, and a fuel A fuel cut control unit 105 that controls the opening and closing operation of the cut valve 123 is provided. In addition, the control means 1
At 00, the counting is started by the operation of each motor 69 on the ascending side or the descending side. The raising / lowering timer 106 that counts the energization permission time t1 (for example, 45 seconds) and the power cut switch 117 is turned on.
Counting is started in synchronization with the operation, and a predetermined set time t
A closing operation permission timer 107 that counts 2 (for example, 15 seconds) is provided. The lifting / lowering timer 106 is connected to both the upward drive control unit 101 and the downward drive control unit 102. It is connected to the drive control unit 102 and the like.

Hereinafter, the contents of control by the control means 100, and the functions and effects will be described with reference to flowcharts.

Ascending drive control First, as shown in FIG. 25, the ascending drive control section 101 controls the ignition switch IG in step S1.
It is determined that the vehicle speed value detected from the vehicle speed sensor 111 is equal to or greater than a predetermined stop state determination value (10 km / h in the example in the figure) on the assumption that the vehicle is in the ON state, and the speed is lower than the stop state determination value. If so, it is determined that the vehicle is stopped.
In step S2, it is determined whether or not the brake switch BR is ON, and in step S3, it is determined whether or not the operation switch 112 has been turned ON to the OPEN position. Then, the vehicle is stopped, the parking brake is activated, and the operation switch 112 is turned on.
If the three conditions of the ON state are satisfied, the motors 69, 69 are driven upward in step S6 through steps S4 and S5, and the lifting roof 53 is raised to the fully open and raised position. It returns to step S1. On the other hand, if even one of the above three conditions is not satisfied, both the motors 69, 69 are stopped in step S7 and the process returns to step S1, and the operator performs the open-side operation using the operation switch 112. Also, the lifting operation of the lifting roof 53 is not performed.

In the above control, in the above step S4, it is determined whether or not the lift roof 53 has reached the fully open ascending position (indicated as the open position) based on whether or not the first limit switch 113 has been turned on. The driving of each motor 69 in step S6 is continued until the state is reached,
If the motor is in the fully-opened ascending state, the motors 69 in step S7
Stop driving. In step S5, the driving of each motor 69 in step S6 is permitted until the energization permission time t1 by the elevating timer 106 started counting by the motor driving in step S6. After the lapse of time, the motors 69 are forcibly stopped in step S7 on the assumption that there is any obstacle that prevents the ascending operation or that the driving force transmission system has a failure. Thus, damage to the elevating roof 53 and the like can be minimized.

In the ascending drive control, when the operation switch 112 is operated to the OPEN position, the parking brake BR is in the operating state, and the vehicle speed is substantially stopped at a vehicle speed lower than the stop state determination value. Since the lifting operation of the lifting roof 53 is allowed only when the lifting operation is performed, the lifting operation of the lifting roof 53 in the traveling state can be reliably prohibited to improve reliability.

-Descent drive control- The control by the descent drive control section 102 is based on the premise that the ignition switch IG is in the ON state.
This is performed as shown in FIG.

First, the operation indicated by A in the time chart of FIG. 28 is performed by controlling the following steps S11 to S25. That is, it is determined whether the first limit switch 113 is in the ON state in step S11.
It is determined whether or not 3 is in the fully-opened state (open position). If it is in the fully-opened state, it is determined in step S12 whether the power cut switch 117 has been turned ON from the OFF state. The power cut switch 117 is ON
If activated, it is determined in step S13 whether or not the close operation permission timer 107 is counting. If not, the count of the close operation permission timer 107 is started in step S14.

Then, in step S15, it is confirmed that the close operation permission timer 107 is counting, and in step S16, the power cut switch 117 is determined.
Confirm that is not turned ON again. afterwards,
That the detected vehicle speed value from the vehicle speed sensor 111 in the step S17 is a stop state lower than the stop state determination value described above;
After confirming that the parking brake is in operation in step S18, the operation switch 1
It is determined whether or not 12 has been turned ON to the CLOSE side.

If the operation switch 112 is turned on, the second limit switch 114 is turned off in step S20.
Confirmation that the FF has not been changed to the ON state, confirmation that the lifting roof 53 has not yet reached the fully closed and lowered position (indicated as the closed position) in step S21, and that 10 seconds have yet to elapse from the start of the lowering operation in step S22. Confirmation that there is no limit switch failure by comparing the states of the third limit switch 115 and the fourth limit switch 116 in step S23, and the above-described energization permission from the start of the descending operation in step S24. After confirming that the time t1 has not elapsed, both motors 69, 69 are driven, and the process returns to step S11. As a result, the lifting roof 53 starts to descend from the fully opened and up state.

As described above, in the operation indicated by A in FIG. 28, after the operator turns on the power cut switch 117, the operator turns on the operation switch 112 to the CLOSE side within a predetermined closing operation permission time t2. Only in this case, both motors 69, 69 are operated to allow the lowering operation of the lifting roof 53. That is, the lowering operation of the lifting roof 53 is permitted only when the operator performs a series of switch operations from the power cut switch 117 on the lifting roof 53 side to the operation switch 112 on the passenger compartment side continuously. Therefore, it is possible to reliably and effectively prevent an erroneous operation for the lowering operation of the lifting roof 53.

Next, the operation indicated by B in FIG. 28 will be described. In steps S11 to S14, the close operation permission timer 107 sets the close operation permission time t2.
If the operation switch 112 is not turned on in step S19 through steps S15 to S18 even if the counting of the motors 69 and 6 is started, the process proceeds to step S27.
9 is left stopped. Then, again, step S
Returning to step S11, the power cut switch 117 has returned to the OFF state in step S12, so the process proceeds to step S15 while the count of the closing operation permission time t2 is continued. Here, if the above-mentioned t2 elapses, the count of the closing operation permission timer 107 has been completed in step S15, so the process proceeds from this step S15 to step S27, where the motors 69, 69 are kept stopped, and Even if the operation switch 112 is operated later, the lifting roof 53 cannot be lowered.

That is, the operation indicated by B in FIG.
Even if the power cut switch 117 is turned on and the operation switch 112 is not continuously turned on, the operator looks at the state of the living space on the main body roof 52 and consciously performs the lowering operation of the lifting roof 53. Rather than trying to do, the ON operation of both are irrelevant,
The lowering operation of the lifting roof 53 is prohibited. Thus, the control for preventing the erroneous operation can be more reliably performed in the lifting device configured to allow the lowering operation of the lifting roof 53 only when both the switches 112 and 117 are operated. .

The control of the operations indicated by A and B in FIG. 28 constitutes the second restricting means in the invention according to claim 5.

Next, the operation indicated by C in FIG. 28 will be described. Similar to the control described in the operation indicated by A in FIG. 28, the motors 69, 6 are determined in steps S11 to S25.
9 is driven, and the lifting roof 53 starts lowering. And when it returns to step S11, since the lift roof 53 has already descended from the fully open rising position, it skips steps S12 to S15 and proceeds to step S16.
Thereafter, in steps S16 to S25, the motor 69,
The driving of 69 is continued. Then, again, step S1
1 and returns from step S11 to step S11.
At step S16, if the power cut switch 117 is turned ON again, the process proceeds from step S16 to step S27.
9. Stop 69. Therefore, even if the operation switch 112 is turned ON to the CLOSE side, the motor 6
9, 69 will be forcibly stopped.

Such control of the operation indicated by C in FIG. 28 constitutes the second limiting means according to the invention of claim 6, and FIG.
The principle of 1 is shown by a flowchart. That is, the determination whether or not the power cut switch 117 is turned ON in step S101 is repeated until the power cut switch 117 is turned ON. When the power cut switch 117 is turned ON, the process proceeds to step S102. This step S102 and S
103, the operation switch 1 within the closing operation permission time t2.
12 to determine whether the CLOSE side has been turned ON,
If the operation switch 112 is turned on within the time t2, the driving of the motors 69, 69 is started in step S104, and the power cut switch 117 is not turned on again by the discrimination in step S105, and the operation of step S106 is stopped. The operation switch 112 is turned off by the determination.
If not, the process returns to the step S104 and the driving of the motors 69, 69 is repeated. However, even if the operation switch 112 remains ON, if the power cut switch 117 is turned ON again, the process proceeds from step S105 to step S107, and the motor 69,
69 is forcibly stopped.

That is, the O of the power cut switch 117
Although the lowering operation of the lifting roof 53 was performed by the ON operation of the operation switch 112 following the N operation, the main body roof 5
When another occupant is left in the living space on the upper side 2 or when the presence of an object such as a sleeping bag that hinders the lowering of the elevating roof 53 is noticed, the power cut switch 117 on the living space side is turned on again. By doing so, the lifting roof 5
3 can be stopped. Therefore, the lowering operation of the elevating roof 53 based on the erroneous operation can be more reliably prevented.

On the other hand, in the flowcharts of FIGS. 26 and 27 described above, if the detected vehicle speed value is higher than the stop state determination value in step S17, and if the parking brake is not operating in step S18, the process proceeds to step S27. The motor 69, 69 is stopped, and the power cut switch 11 is turned on unless the vehicle is stopped and the parking brake is not activated.
Even if both the switch 7 and the operation switch 112 are turned ON, the motors 69, 69 are not driven. Accordingly, the lowering operation of the elevating roof 53 when the vehicle is in the running state can be reliably prevented, and the reliability of the lowering operation can be further improved. In steps S16, S17,
And S27 constitutes the first limiting means 132.

When the lifting roof 53 is lowered,
The second limit switch 114 is turned off in step S20
From the step S20 to the step S27, the driving of the motors 69, 69 is stopped, and the process returns to the steps S11, S16 to S16.
By repeating step 25, the driving of the motors 69, 69 is restarted. As described above, the lift roof 53 temporarily stops at the intermediate position (intermediate stop position) between the fully open ascending position and the fully closed and lowered position during the lowering operation. Then, after the resumption of the driving, the third and fourth limit switches 115 and 116 are both turned off when the lift roof 53 reaches the fully closed and lowered position in step S21.
If it is detected that the motor is turned on, the process proceeds to step S27, in which the driving of the motors 69, 69 is stopped.
Thereby, the arrival at the fully closed lowering position is reliably detected, and the lift roof 53 can be reliably brought into the fully closed lowering state.

Further, immediately before reaching the fully closed lowering position in step S22, in step S23, the third fully closed lowering position is detected in step S21.
Then, the failure diagnosis of the fourth limit switches 115 and 116 is performed. That is, in step S23, the third
If either one of the limit switch 115 or the fourth limit switch 116 is turned ON from OFF and the state remains, for example, for 8 seconds, it is determined that one of the limit switches 115 or 116 has failed. Then, the process proceeds to step S27, where the motor 69,
Forcibly stop the drive of the motor 69. Thereby, the two limit switches 115 and 116 for detecting the fully closed lowering position are provided.
Even if one of them is broken down or cannot be detected due to interference of foreign matter, the lifting roof 53 can be reliably stopped at the fully closed and lowered position.

—Warning Buzzer Control— The control by the warning buzzer control unit 103 is performed as shown in FIG.

That is, in step S31, if the lift roof 53 is at the fully closed and lowered position (indicated as the closed position), the process proceeds to step S40 described later. If it is at a position other than the fully closed and lowered position, the process proceeds to step S32. If the detected vehicle speed value is equal to or greater than the stop state determination value (10 km / h) in step S32, the process proceeds to step S33, in which the warning buzzer 121 is sounded at a TYPE2 sounding cycle, which will be described later, and the vehicle is in the running state and the elevator roof 53 Warns the occupants that they must not perform any lifting operations.

If it is determined in step S32 that the detected vehicle speed is lower than the stop state determination value and the vehicle is in a stopped state, the process proceeds to step S34, where it is determined whether or not the lift roof 53 is at the fully open ascending position. It is determined by the 1 limit switch 113, and if it is not at the fully open ascending position, step S35
In step S36, it is determined whether or not the operation switch 112 has been turned ON to the OPEN side.
It is determined whether the ON operation has been performed on the LOSE side. Then, the operation switch 112 is set to the OPEN side,
If neither the ON operation on the LOSE side has been performed, the process proceeds to step S37, and the warning buzzer 121 is set to a TYPE described later.
By sounding in one sounding cycle, the occupant is warned that the lift roof 53 is at an intermediate position between the fully open ascending position and the fully closed and descending position, and either the ascending or descending operation is required.

If it is determined in step S34 that the lifting roof is at the fully-opened ascending position, the flow advances to step S38 to determine whether or not the closing operation permission timer 107 is counting the closing operation permission time t2. Proceeding to step S33, the warning buzzer 121 is sounded at the sounding cycle of TYPE2, and the power cut switch 117 is turned off.
N is activated, and the occupant is warned that the operation switch 112 needs to be turned ON to the CLOSE side while the timer 107 is counting. On the other hand, if the counting is not being performed, the power cut switch 117 is not turned on, or even if the power cut switch 117 is turned on, the counting by the timer 107 has already been completed. Determine whether there is
If not, the process proceeds to step S37, and the warning buzzer 1
21 is sounded in the sounding cycle of TYPE 1 to warn the occupant that it is necessary to stop the vehicle in order to perform the elevating operation of the elevating roof 53.

If the parking brake is in operation in step S39, the lifting roof 53 is moved in step S40.
In step S41, it is determined whether the ascending / descending roof 53 is in descending operation.
If any of them is operating, the process proceeds to step S37, and the warning buzzer 121 is sounded at the sounding cycle of the TYPE1.
While warning the occupant that the lifting roof 53 is performing the lifting operation, if neither the lifting operation nor the lowering operation is performed, the process proceeds to step S42 to stop the warning buzzer 121.

The alarm buzzer sounds at the above-mentioned TYPE 1
And TYPE2, TYPE1 has a buzzer ON of 125 msec for 25 times as shown in FIG.
The buzzer O is repeated twice at intervals of 0 msec.
N is repeated at intervals of 750 msec. Also,
As shown in FIG. 32, TYPE2 is such that a buzzer ON of 125 msec is continuously repeated at intervals of 250 msec. In other words, the warning buzzer 121 is sounded in the above-described step S33 at the sounding cycle of TYPE2 so that the warning by the sound is made more recognizable to the occupant.

—Warning Lamp Control— The control by the warning lamp control unit 104 is performed as shown in FIG.

That is, in step S43, a short time (6 seconds in the example shown in the figure) for checking the disconnection after the ignition switch IG changes from the OFF state to the ON state.
During ec), the warning lamp (warning lamp) 122 is continuously turned on in step S44, and the routine returns. When the check of the centering is completed, a warning buzzer 121 is issued in step S45.
Is diagnosed, and the failure diagnosis of the third and fourth limit switches 115 and 116 for detecting the fully closed and lowered position of the lifting roof 53 is performed in step S47.
If the warning buzzer 121 is sounding, or if the limit switch 115 or 116 is out of order, the process proceeds to step S46, where the warning lamp 122 is flashed. Give more attention to give. On the other hand, the warning buzzer 121 is stopped and the limit switch 1
If 15, 116 is normal, the process proceeds to step S48, and the warning lamp 122 is turned off. Warning lamp 1 above
As shown in FIG. 34, the blinking of 22 repeats lighting for 0.5 sec at 1.0 sec intervals.

-Fuel cut control-As shown in FIG. 35, the fuel cut control unit 105 determines whether or not the lift roof 53 is at the fully closed and lowered position in step S51, and determines whether or not the parking brake is in step S52. It is determined whether or not it is in the operating state. If the lift roof 53 is in the fully-closed lowering position, or is not in the fully-closed lowering position but the parking brake is in operation, the process proceeds to step S53, in which the fuel cut relay is kept in the OFF state, and the fuel is cut off. The cut valve 123 is opened so that fuel can be supplied to the engine. However, if the lift roof 53 is not in the fully closed and lowered position, that is, the parking brake is not actuated in spite of being in the fully open ascent position or the intermediate stop position, step S
Proceeding to 54, the fuel cut relay is turned ON to close the fuel cut valve 123, and the supply of fuel to the engine is forcibly shut off to disable running. As a result, it is possible to reliably prohibit the vehicle from traveling in an unstable state due to an increase in the center of gravity of the vehicle, such as when the lift roof 53 is at the fully-opened ascending position or the intermediate stop position. <Other Aspects> In the second and third embodiments, the erroneous operation preventing means is constituted by the power cut switch 55 so as to electrically prohibit the elevating operation of the elevating roof 53.

In this case, the micro switch 96, which is an erroneous operation prevention means, is disposed on the rail 64 that guides the elevating roof 53 to move up and down. The operation of lowering the elevating roof 53 is prohibited. In other words, since the micro switch 96 is in the OFF state, the motor 69 is not driven even when the operation switch 55 is operated, and the lift roof 53 does not descend, and the lift roof 53 is engaged with the locked member 93 and the claw member 94. It is also mechanically locked so that it does not descend in a relationship.

At the time of returning to the fully closed lowering state, if the operation portion 94b of the claw member 94 is gripped and turned upward in FIG. 36, the engagement with the locked member 93 is released and the micro member is released. The switch 96 is also turned on (closed). Therefore, if the operation switch 55 is operated, the motor 6
9 drives and the lifting roof 53 descends. In addition, 45 is a battery. The invention in such an aspect is the invention according to claims 2 and 3.
