According to the invention of claim (3), since the distortion detection means is disposed on the roof panel around the roof opening, when an intruder from the roof opening distorts the roof panel, the intrusion is immediately detected. Detected.

According to the invention of claim (4), when solar radiation is blocked by an intruder through the roof opening and a change occurs in the output of the cell element of the solar cell, the intrusion is immediately detected.

(Example) Embodiments of the present invention will be described in detail below with reference to the drawings.

Example 1 In this example, infrared beam means is used as a person detection means.

In FIGS. 1 and 2, 1 is a roof panel, 2 is a roof opening, and a sunroof 3 (slide roof) is disposed in such a manner that it can be opened and closed. An infrared beam radiator 5 and an infrared beam receiver 6 are disposed in an extension 4 extending downward from the peripheral edge of the roof opening 2 so as to face each other.

The frame member 7 that supports the sunroof 3 has roof rails 8 (
It is connected to the roof rail outer 8a and the roof rail inner 8b via a pair of members 9 and 1o, and is attached to a fixing plate 11 fixed to the extension part 4. 12 is a top ceiling.

Opening/closing control of the sunroof 3 during ventilation is performed by the controller 20. As shown in FIG. 3, the controller 20 includes a ventilation determining means 31 that receives signals from a keyless switch 21, an outside temperature sensor 22, a room temperature sensor 23, and a vehicle speed sensor 24, and determines whether or not the vehicle is in a ventilation area. , a person detection means 32 that receives a signal from the infrared beam receiver 6 and detects an intrusion of a person through the roof opening 2. In addition, receiving the output of the ventilation condition determining means 31,
In the ventilation area, for example, a ventilation control means 33 operates a ventilation fan 25 disposed in the trunk room, and upon receiving a signal from the ventilation control means 33, operates a drive motor 26 of the sunroof 3 during parking ventilation to operate the sunroof 3. while receiving the output of the human detection means 22,
At least the drive motor 26 is damaged due to human intrusion during parking ventilation.
drive means 34 for sending a signal to close the sunroof 3;
It also has

An example of ventilation control by the controller 20 will be explained based on FIG. 4.

For example, when the ventilation switch is turned on, a ventilation determination is first made to determine whether or not the ventilation area is present (step SL).

If it is in the ventilation area, the ventilation fan 26 is activated, the sunroof 3 is fully opened, and the infrared beam radiator 5 emits an infrared beam (step S2).

Then, it is determined whether or not the infrared beam is blocked (step S3), and if the infrared beam is blocked, the roof opening 2
Since it is thought that there is an intruder through the system, the sunroof 3 is fully opened (step S4), a predetermined time is counted (step S5), and after the predetermined time elapses, the process returns. On the other hand, if the beam is not blocked, the process returns to step S2 to continue ventilation.

Further, if it is determined in step SL that the ventilation area is not reached, the process returns to step S1 and the determination of ventilation conditions is repeated until the ventilation area is reached.

Example 2 In this example, a strain gauge is used as the person detection means.

As shown in FIGS. 5 and 6, strain gauges 41, 41° 41, 41 are disposed around the front portion (opened side) of the roof opening 2 formed in the roof panel 1. ing.

The strain gauges 41 are disposed below the roof panel 1 and are connected in series as shown in FIG. It is designed to let you do so.

Next, an example of ventilation control by the controller 42 will be explained with reference to FIG. 8.

For example, when the ventilation switch is turned ON, a ventilation determination is first made to determine whether or not the ventilation area is present (step 511).

If it is in the ventilation area, the ventilation fan 25 is activated and the sunroof 3 is fully opened (step 512). This provides ventilation.

Then, it is determined whether or not there is any distortion in the roof panel 1 (step 513). If there is any distortion, it is considered that there is an intruder, so the sunroof 3 is fully opened and step 5
14), a predetermined period of time elapses (step 515), and then the process returns to step Sll.

On the other hand, if there is no distortion in the roof panel 1, the process returns to step S12.

Further, if it is determined in step Sll that the ventilation condition is not in the ventilation area, the determination of ventilation conditions is repeated.

Example 3 This example utilizes changes in the output of the battery elements of a solar cell.

As shown in FIG. 9, a solar cell 51 is mounted on the sunroof 3 to drive the ventilation fan 25 during parking ventilation, and the solar cell 51 is connected to a plurality of battery elements 51.
It is divided into a, 51a/old... (solar cell module). In addition, in FIG. 9, the solar cell 51 is 18
The battery element 51a is divided into two.

As shown in FIG. 10, it is determined whether each battery element 51a has the same output by a controller 52 serving as an output determining means. However, if the outputs of the battery elements 51a are not the same, it is considered that, for example, a person's hand P (see FIG. 9) is resting on the roof panel 1, which is causing the shadow. ,
It is determined that there is a person and an alarm 53 is sounded.

Control by the controller 52 will be explained based on FIG. 11.

For example, when the ventilation switch is turned on, a ventilation determination is first made to determine whether or not the ventilation area is present (step S21).

If it is in the ventilation area, the ventilation fan 25 is activated and the sunroof 3 is partially closed (step 522).

Then, it is determined whether each cell element 51g of the solar cell 51 is outputting uniformly (step 528),
If it is not uniform, it is considered that there is an intruder, so the alarm 53 is activated (step 524). Note that at this time, the sunroof 3 is fully closed.

On the other hand, if the output is uniform, it is considered that there is no intruder, so the process returns to step 822 and ventilation continues. As a result, as shown in FIG. 12, outside air is introduced through the roof opening 2, and the ventilation fan 2 at the rear of the vehicle
6, the air inside the vehicle is exhausted.

Further, if it is determined in step 521 that the air conditioner is not in the ventilation area, this determination is repeated.

Note that the number of battery elements 51a whose output has decreased is 1 to 2.
If the number of alarms exceeds the number of alarms, it may be because the alarm is in the shadow of a tree, so in such a case, the alarm 53 may not be activated even if the output decreases. .

In all of the above embodiments, the sunroof 3 is closed when an intruder is detected, but since closing the sunroof 3 reduces ventilation performance, the roof 3 is closed as shown in FIGS. 13 to 15. The opening 2 is covered with a highly breathable mesh member 6.
1 may be used to close the block. That is, in addition to the drive motor 26 and the drive cable means 62 for opening and closing the sunroof 3, there is also a net member 61, a drive motor 64 for driving it, and a drive cable on the front part of the frame member 63 constituting the sunroof unit. A cable means 65 is provided to allow the net member 61 to move in and out of the roof opening 2.

The blockage by the net member 61 may be closed when an intruder is detected, or may be closed from the beginning of ventilation.

In addition, since the roof opening 2 is opened for ventilation, in order to prevent dust from entering through the open part, an electrode of a static electricity generator is placed on the side of the roof opening 2 to prevent dust from entering from outside. It is also possible to prevent the intrusion of

(Effect of the invention) According to the invention of claim (1), the roof opening located above can be used as a ventilation opening during ventilation, so ventilation can be performed efficiently. Since intrusion through the computer is detected, theft can be prevented.

According to the inventions of claims ('2J and (3)), since a person is detected using an infrared beam and a strain gauge, an intruder can be reliably detected with a simple structure.

According to the invention of claim (4), since the battery element of the solar battery, which is the driving source during parking ventilation, is used to detect a person, it is possible to easily detect intruders without installing any special equipment. Can be detected.
