JPH0357717A - Power window controller - Google Patents

Abstract

PURPOSE:To dispense with switch operation by actuating a power window for its opening when door opening has been detected and room temperature has exceeded a fixed value. CONSTITUTION:Detection signals are inputted from a door opening and a room temperature detecting devices 12 and 14 into a controller 10 respectively. When a door opening detection signal has been inputted and detected room temperature has exceeded a fixed value, the controller 10 gives a door opening command to a power window 16. This makes the switch operation of the power window unnecessary and the use of the power window more convenient.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a power window control device.

(b) Conventional technology The windows of vehicles equipped with power windows can be opened and closed centrally using the window opening/closing switch located on the driver's seat.
(Refer to "Automotive Engineering Handbook" Volume 3 II-1148-150)
.

(c) Problems to be Solved by the Invention However, the conventional power window control device as described above has a problem in that the window cannot be opened unless the driver intentionally operates the window opening/closing switch. There is. For example, when getting into a vehicle that has been parked under the scorching sun, you must first enter the hot interior of the vehicle, turn on the ignition key, and then operate the window opening/closing switch, which can be cumbersome in a hot environment. Operation is required. The present invention aims to solve these problems.

(2) Means for Solving the Problems The present invention provides a method for automatically operating a power window to open the window and ventilate the vehicle if the temperature inside the vehicle exceeds a predetermined value when the door is opened. This solves the above problem. That is, the power window control device according to the present invention includes a door open detection device (12) that detects that an operation to open the door has been performed, a room temperature detection device (14) that detects the temperature inside the vehicle, and a door open detection device (14) that detects the temperature inside the vehicle. The controller (10) operates the power window (16) to the open side when the open detection device detects an opening operation of the door and the room temperature detection device detects a temperature higher than a predetermined temperature. .

Note that the symbols in parentheses indicate corresponding members in the embodiments described later.

Note that it is also possible to provide a rain detection device that detects a rain condition, and to stop outputting a signal from the controller instructing to open the window when a rain condition is detected.

Furthermore, the windows can be automatically closed when the door locking device is set to a key-locked state (activating the locking device from outside the vehicle using a key).

Furthermore, the window may be automatically closed when the temperature of the air outlet from the air conditioner falls below a predetermined value.

(e) Effect: For example, if you open a door while the car is parked in the hot sun, the door opening detection device will detect this, and in this case, the room temperature detection device will detect that the temperature inside the vehicle is above a predetermined value. , the controller outputs a signal to operate the power window to the open side. This opens the window and exhausts the high temperature air inside the vehicle to the outside of the vehicle. Therefore, high-temperature air can be quickly discharged to the outside of the vehicle interior, and there is no need to enter the interior of the vehicle and operate the switch for opening/closing the power window.

Additionally, if it is raining, it can be detected and the window can be prevented from opening. Thereby, rain can be prevented from blowing into the vehicle interior.

Furthermore, the window can be automatically closed when the door locking device is key-locked. This results in
There is no need for the troublesome operation of closing the window when the door is opened but the door is closed again without getting into the vehicle.

Furthermore, when the air conditioner is activated and the temperature of the air blown out from the outlet drops to a predetermined value, the window can be automatically closed. In this case as well, no operation is required to close the window.

(f) Example (First example) FIG. 1 shows a first embodiment of the present invention as a block diagram.

Signals from a door open detection device 12 and a room temperature detection device 14 are input to a controller 10 having a microcomputer. The door open detection device 12 includes a switch that is turned on when the driver's door is opened. The room temperature detection device 14 is a device that detects the air temperature inside the vehicle interior. The controller 10 outputs a signal instructing the operation of the power window 16 based on signals from the door open detection device 12 and the room temperature detection device 14.

Next, the details of the control performed by the controller 10 will be explained according to the control flow shown in FIG. First, it is determined whether the door opening detection device 12 detects the opening of the door (step 102), and if the door is opened, whether the temperature detected by the room temperature detection device 14 is equal to or higher than a predetermined value. 104), and if the value exceeds a predetermined value, the power window 16 is operated and all windows are opened (106). If the door is not opened in step 102 and if the temperature is below the predetermined value in step 104, the window is not opened.

After all, with the above control, when the door is opened while the temperature inside the vehicle is high, the window is opened by the power window 16 and ventilation is performed. This allows the high-temperature air inside the vehicle to be discharged to the outside of the vehicle, eliminating the need for the driver to perform troublesome operations in a high-temperature environment at the start of driving.

(Second Embodiment) A second embodiment is shown in FIGS. 3 and 4. This second embodiment is such that a rain detection device 18 is added to the first embodiment, and when a rain condition is detected, the window opening operation by the power window 16 is not performed (steps in Fig. 4). 105). As a result, the windows will not be opened during rainy conditions, and rain can be prevented from blowing into the vehicle interior.

(Third Embodiment) A third embodiment is shown in FIGS. 5 and 6. This third embodiment is
A key lock detection device 20 is provided in the second embodiment, and the window is automatically closed when a key lock (i.e., activation of a lock device from outside the vehicle using a key) is detected. It is something. That is, when the power window 16 is automatically operated and the key lock state is detected by the key lock detection device 20C with the window opened (see step 108), the alarm device 22 is activated,
An audio warning is output (110), and then the power window 16 is activated and closed (112)
). As a result, for example, if the door is opened but the door is closed without getting into the vehicle and the locking device is activated to the lock side with the key, the window will be automatically closed and there will be no need to close the window again. No further operation is required.

(Fourth Example) A fourth example is shown in FIGS. 7 and 8. This fourth embodiment is
The third embodiment is provided with an air conditioner M temperature detection device 24 so that the window is closed when the air conditioner is in a state where it can effectively operate. That is, the air conditioner wind temperature detection device 24 detects the temperature of the air blown out from the air outlet of the air conditioner, and when the detected temperature is below a predetermined value (see step 109), This system outputs an alarm and closes the windows. As a result, the C window is automatically closed as soon as the air conditioner becomes effective, eliminating the need for the driver to operate a switch.

(g) Effects of the Invention As explained above, according to the present invention, when the door is opened when the temperature inside the vehicle is above a predetermined value, the window is automatically opened by the power window. This eliminates the need for troublesome switch operations in the high-temperature interior of the vehicle, allowing the user to ride in the vehicle in a slightly better environment.
