In a conventional vehicle disclosed in Japanese Patent No. 2787671, a roof structure 502 having a front roof 500 and a rear window 501 is opened and closed by the action of a roof opening and closing drive mechanism 503 as shown in FIG. A closed position shown by a solid line in the drawing and a storage position shown by a two-dot chain line in the drawing are taken. The trunk lid 504 is rotated by the operation of the first trunk lid opening / closing mechanism 506 including the auxiliary frame 505 and the like.
It is opened and closed back and forth with the fulcrum 7 as a fulcrum. The opening / closing operation of the trunk lid by the first trunk lid opening / closing mechanism 506 is executed when the roof structure 502 is shifted from the closed position to the storage position or vice versa. Meanwhile, trunk room 508

Trunk closing control means for controlling the driving of the motor to rotate the trunk lid to the closing side with the rear end of the trunk lid serving as a fulcrum until the lock-on of the first lock mechanism is detected. .

According to the third aspect of the present invention, when the trunk is closed by a driver or the like and the second lock mechanism is in the lock-on state when the trunk room is open, the trunk is responded to the second lock mechanism. The lid rotation motor is driven to close the trunk lid, whereby the first lock mechanism is also brought into the lock-on state. In this way, according to the third aspect of the invention, when the rear end of the trunk lid is closed by hand or the like, the front end of the trunk lid that has been lifted upward is automatically lowered to the original position thereafter, and the lock is locked. Will be done.

When opening the roof, the driver first switches the roof open / close switch 60 provided at an appropriate position in the vehicle from the closed position to the open position (step 100).

When the control circuit 90 detects the operation of switching the roof open / close switch 60 to the open position, the control circuit 90 detects the state of the front lock mechanism based on the detection output of the front lock open / close detection sensor 62 (step 101).
When the front lock mechanism is in the open state, the control is shifted to the next procedure.

When the front lock mechanism is in the open state,
First, the control circuit 90 gives a command to the door glass motor drive circuit 54 to open the door glass 70 (step 102). When the opening operation of the door glass 70 is completed (Step 103), the control circuit 90 next gives a command to the rearward-slant glass motor drive circuit 55 to open the rear-slant glass 71 (Step 104). When the opening operation of the inclined glass 71 is completed (Step 105), the control circuit 90 gives a command to the frame lock actuator 50 to unlock the frame lock 43 (Step 106). As a result, the trunk frame 19 is in a state where the trunk frame 19 can be rotated around the rotation shaft 26 using the power of the T / L motor 33.

Next, the control circuit 90 gives a forward rotation command to the T / L motor drive circuit 53, and starts rotating the T / L motor 33 to rotate forward (to open the trunk lid 17). (Step 107). During this rotation, T /
When a detection signal is input from the L53 ° open sensor 68 (step 108), the control circuit 90 outputs a stop command to the T / L motor drive circuit 53 to stop the T / L motor 33 (step 109). In this way, the trunk lid 17 is opened to an angle that does not hinder the storage of the roof as shown in FIG. 8, for example, and is stopped in this state.

Next, the control circuit 90 gives a command to the roof motor drive circuit 52 to start the rotation drive of the roof motor 15 to the forward rotation side (to open the roof) (step 110). During this rotation, the roof open detection sensor 6
5 (step 111), the control circuit 90 outputs a stop command to the roof motor drive circuit 52 to stop the roof motor 15 (step 112). Thus, the roof mechanism 4 is stored in the trunk room 36 as shown in FIG.

Next, the control circuit 90 gives a reverse rotation command to the T / L motor drive circuit 53, and starts the rotation drive of the T / L motor 33 to the reverse rotation side (the side for closing the trunk lid 17) ( Step 113). During this rotation, when a lock-on detection signal is input from the frame lock open / close detection sensor 63 (step 114), the control circuit 90 sets T
/ L outputs a stop command to the motor drive circuit 53,
The L motor 33 is stopped (Step 115). Thus, the trunk lid 17 is returned to the original closed state. Further, the control circuit 90 drives the closing of the rear glass 71 after driving the closing of the door glass 70 (step 11).

As described above, the roof opening operation for storing the roof mechanism 4 in the trunk room 36 is performed.

Next, the procedure for closing the roof will be described with reference to FIG. When closing the roof, the respective parts operate in the order of FIG. 9, FIG. 8, and FIG.

When the roof is open, only the front lock mechanism for fixing / releasing the front roof 2 to / from the front window frame is in the released state, as shown in FIG. The lock mechanism 42 is in a lock-on state.

To change the roof from open to closed, the driver first operates the roof open / close switch 60 from the open position to the closed position.

When the control circuit 90 detects this (step 201), first, the door glass motor drive circuit 5
4 is instructed to open the door glass 70 (step 202). When the end of the opening operation of the door glass 70 is detected (step 203), the control circuit 90 next gives a command to the rear glass motor drive circuit 55, and the rear glass 7 is controlled.

A state in which it is possible to rotate backward using the rotation shaft 26 as a fulcrum using the power of the T / L motor 33 is enabled.

Next, the control circuit 90 issues a normal rotation command to the T / L motor drive circuit 53 in the same manner as described above.
The T / L motor 33 is driven to rotate forward (to open the trunk lid 17), and the trunk frame 19 is rotated by a predetermined angle (for example, 53 degrees) (steps 207 to 209). . As a result, trunk lid 1
7 is opened to a state as shown in FIG. 8 and stopped in this state.

Next, the control circuit 90 gives a command to the roof motor drive circuit 52 to start rotating the roof motor 15 in the reverse direction (to close the roof) (step 210). During this rotation, the roof closing detection sensor 6
When the detection signal is input from the control circuit 6 (step 211), the control circuit 90 outputs a stop command to the roof motor drive circuit 52 to stop the roof motor 15 (step 1).
12). Thus, the roof mechanism 4 is returned to the closed position shown in FIG. In this case, since the lock on / unlock of the front lock mechanism is manually performed, the stop of the roof motor 15 is performed based on the output of the roof close detection sensor 66. When the mechanism is automatically locked on / released using a solenoid or the like, the stop of the roof motor 15 may be performed based on the output of the front lock open / close detection sensor 62.

Next, the control circuit 90 gives a reverse rotation command to the T / L motor drive circuit 53, and starts the rotation drive of the T / L motor 33 to the reverse rotation side (the side for closing the trunk lid 17) ( Step 213). During this rotation, when a lock-on detection signal is input from the frame lock open / close detection sensor 63 (step 214), the control circuit 90 sets T
/ L outputs a stop command to the motor drive circuit 53,
The L motor 33 is stopped (Step 215). Thus, the trunk lid 17 is returned to the original closed state. Further, after driving the door glass 70 to close, the control circuit 90 drives the rearward inclined glass 71 to close (step 21).
6-219).

Thereafter, the driver manually sets the front lock mechanism in the lock-on state (step 22).

The roof closing operation is executed as described above.

Next, the trunk opening operation will be described with reference to FIG. FIGS. 10 and 11 show the movement of each part when the trunk is opened and closed.

First, when opening the trunk lid 17, the driver opens the key switch of the trunk. As a method of opening the key switch of the trunk, there are a method of directly keying into the key switch of the trunk, a method of opening the key switch of the trunk using a trunk open button or a trunk open lever provided in the vehicle, and the like. Therefore, any of these operations may be selectively used.

When the control circuit 90 detects that the driver has issued a trunk opening request based on the output of the trunk key SW opening detection sensor 61 (step 300), first, the frame lock 43 is unlocked (step 30).
1). As a result, the trunk lid 17 can be turned around the turning shaft 26 by using the power of the T / L motor 33.

Next, the control circuit 90 gives a forward rotation command to the T / L motor drive circuit 53, and drives the T / L motor 33 to rotate forward (to open the trunk lid 17) (step). 302). At the time of this rotation, T / L10
When the detection signal is input from the open sensor 67 (Step 303), the control circuit 90 outputs a stop command to the T / L motor drive circuit 53 to stop the T / L motor 33 (Step 304). As a result, the trunk lid 17
Is raised by a predetermined height and slightly displaced rearward as shown in FIG. Regarding the rising height of the trunk lid 17, that is, the turning angle of the trunk frame 19, the opening operation of the trunk lid 17 as shown in FIG. 11 is executed after the front end of the trunk lid 17 does not interfere with the vehicle body. Set values that can be used.

Next, the control circuit 90 gives a lock release command to the T / L lock actuator 50 to release the lock of the T / L lock 41, so that the driver can use the second trunk hinge 20, the gas stay 23 and the like. The trunk lid opening / closing mechanism is used to open the trunk freely (step 305). The trunk is
Thereafter, it is opened manually or by the force of the gas stay 23 (step 306). FIG. 11 shows a state where the trunk is opened.

Next, the trunk closing operation for closing the trunk lid 17 will be described with reference to the flowchart of FIG.

When closing the trunk opened as shown in FIG. 11, the driver manually closes the trunk lid 17 (step 400). Of course, in this state, the front end of the trunk lid 17 has been slightly lifted upward by the previous opening operation. When the driver closes the trunk, the T / L lock 42 is locked, and each part of the vehicle is in a state as shown in FIG.

When the control circuit 90 detects that the T / L lock mechanism 42 is locked based on the output of the T / L lock opening / closing detection sensor 64 (step 401), the T / L lock is set.
A reverse rotation command is given to the motor drive circuit 53, and the T / L motor 33 is driven to rotate in the reverse direction (to close the trunk lid 17) (step 402). At this rotation, when detecting that the frame lock 43 is locked on based on the detection signal of the frame lock opening / closing detection sensor 63 (step 403), the control circuit 90 issues a stop command to the T / L motor drive circuit 53. Output, T / L motor 33
Is stopped (step 404). In this way, the trunk will be closed.

As described above, in this embodiment, the front edge of the trunk lid 17 is displaced upward and backward so that the front edge 18 of the trunk lid 17 does not interfere with the vehicle body when the trunk room 36 is opened and closed. Instead of using a complicated mechanism such as a seven-bar link mechanism, a trunk lid opening / closing mechanism including a T / L motor 33 prepared for roof opening / closing is used instead. . That is, when opening the trunk,
The frame lock 43 is released, and the trunk lid can be turned around the shaft 26 as a fulcrum.
By driving the L motor 33, the front end side of the trunk lid 17 is raised to a position where the interference contact does not occur.
Then, after this, the T / L lock mechanism 42 is released,
The trunk lid 17 is made freely openable and closable. Therefore, in this embodiment, a complicated mechanism such as a conventional seven-bar linkage can be omitted, and the trunk hinge can be a simple mechanism. Therefore, the cost of the vehicle can be reduced, the number of parts can be reduced, and the mounting and adjustment of the trunk lid opening / closing mechanism can be facilitated.

In the roof opening procedure shown in FIG. 12 of the above embodiment, when the roof open / close switch 60 is switched to the roof open position, the output of the front lock open / close detection sensor 62 is used to lock the front lock mechanism. When it has been released, the subsequent roof opening control is executed. However, when the front lock mechanism is manually controlled, the roof open / close switch 60 is operated without detecting whether the front lock mechanism is locked. After switching to the roof open position, the subsequent roof open control may be executed unconditionally.

In the above embodiment, as shown in FIG. 1, the control system is a control circuit 90 such as a microcomputer.
, But the control system may be constituted by an electric circuit using various switches and relays.

The first opening and closing of the trunk lid 17
The second trunk lid opening / closing mechanism and the roof opening / closing mechanism may adopt any other configuration as long as they can perform operations equivalent to those of the above-described embodiment.

The trunk lid opening / closing control device of the present invention may be applied to not only a hardtop vehicle but also a softtop open car such as a hood.

According to the first aspect of the present invention, the first trunk lid opening / closing mechanism for rotating the trunk lid around the rear end side to accommodate the roof structure in the trunk room, and for the use of a normal trunk room. A trunk lid opening / closing control device having a second trunk lid opening / closing mechanism that rotates the trunk lid around its front end side,
In order to eccentrically move the front edge of the trunk lid upward and backward so that the front edge of the trunk lid does not interfere with the vehicle body when opening and closing the trunk room, a complicated mechanism such as a seven-bar link mechanism is used as in the past. Instead, the first trunk lid opening / closing mechanism prepared for opening / closing the roof is used, so that a complicated mechanism such as the conventional seven-bar linkage mechanism can be omitted. The cost of the vehicle can be reduced, the number of components can be reduced, and the mounting and adjustment of the trunk lid opening / closing mechanism can be facilitated.

According to the third aspect of the present invention, when the rear end of the trunk lid is closed by hand or the like, the front end of the trunk lid that has been lifted upward is automatically lowered to its original position and locked. Therefore, the driver is not required to perform an extra operation, and the lock is not forgotten.
