Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power window control device for a vehicle, and in particular, it is enabled to operate at all times when the ignition switch is in the on position, and when the ignition switch is turned off. The present invention relates to a power window control device for a vehicle that can operate the power window only within a predetermined time from when the power window is turned off and only when the driver's door is open.

As a power window control device for vehicles, it is equipped with an auto-operated switch that activates the relay by simply pressing the UP or DOWN side temporarily, and automatically opens and closes when fully open or fully closed, and after the ignition switch is turned off. A device that improves operability by allowing the power window to operate for a predetermined period of time is being considered. FIG. 1 shows this vehicle power window control device, which is composed of a battery 1, an ignition switch 2, a relay coil 3a, and a contact 3b.The relay 3 turns on the contact 3b when the ignition switch 2 is turned on. and automatic operation and the first one that opens and closes the front right window.
a second switch _4b that opens and closes the front left window, a third switch 4c that opens and closes the rear right window, and a fourth switch 4d that opens and closes the rear left window. , the fifth switch _4a2 , which can open and close the front left and rear left and right windows, and the ignition switch 2 are turned on, and after being turned off, the fifth switch 4a2 is turned on for a predetermined period of time, e.g. A timer 5 that turns on the relay 5a for a certain period of time, and first to fourth motors 6a, 6b, 6c, and 6d that drive to open and close the front right and left windows, and the rear right and left windows, respectively. , a hold circuit 7 that is turned on for a predetermined period of time when the first switch _4a1 is activated for automatic operation, and a fifth
The first switch _4a1 and the _fifth switch _4a2 constitute a main switch and turn on the relay 5a. receives power supply from the second to fourth switches 4
b, 4c, and 4d are configured to receive power supply via the relay 3.

Incidentally, an example of the structure of the hold circuit 7 is shown in FIG. 3, and a terminal 15 connects the battery and the hold circuit 7 via a relay 5a.
It is configured to have terminals 11, 12, 13 connected to terminals ₁ , 2, 3 of the first switch 4a1, respectively, and terminals 14, 17 connected to the motor 6a.

In the above configuration, when the ignition switch 2 is turned on, the contact 3b of the relay 3 is turned on and the relay 5a is also turned on.
via the second switch 4b and the third switch 4
c and terminal 4 of the fourth switch 4d;
The first switch _4a1 is connected via the relay 5a and the hold circuit 7, and the fifth switch is connected via the relay 5a.
Connect battery 1 to terminal 5 of switch 4a and ₂ respectively.
power is supplied. Therefore, when the ignition switch 2 is on, all of the first switch _4a1 to the fifth switch 4a2 are ready to operate, so it is necessary to turn on the lock switch ₈ to release the interruption of the ground circuit. Then, by operating the first to fourth switches 4a ₁ , 4b, 4c, and 4d, the front, rear, left, and right windows can be opened and closed separately, and the driver's seat can be opened and closed by operating the fifth switch 4a ₂ . You can open and close the windows on the front left, rear left and right doors while staying inside. In this state, the lock switch 8 is turned off and the second to fifth switches 4b, 4c,
When 4d and 4a ₂ are cut off from the ground circuit, it becomes impossible to open and close the windows of the front left and rear left and right doors, and only the front right window can be opened and closed by operating the first switch 4a ₁ . Next, when the ignition switch 2 is turned off, the timer 5 is turned on from that point on, for example, for 30 seconds.
The relay 5a continues to be on, but since the relay 3 is turned off, the fourth switches 4b, 4c,
The supply of battery power to the switch 4d is cut off, and the front left window, rear left and right windows cannot be opened or closed by operating these switches 4b, 4c, and 4d. However, since the hold circuit 7 and the fifth switch _4a2 are connected to the battery 1 via the relay 5a, the fifth switch _4a2 is operated by turning on the first switch _4a1 and the lock switch 8. This allows you to open and close the front right side windows, front left side windows, rear left and right windows while in the driver's seat.
In other words, after turning off ignition switch 2, the main switch operated from the driver's seat,
In other words, each window cannot be opened or closed unless the first and fifth switches 4a ₁ and 4a ₂ are operated.

Here, when opening and closing the front left window,
The second switch 4b and the fifth main switch
An example using the first switch 4a ₂ and the first switch 4a ₁ will be shown.

(1) When operating the second switch 4b In this case, it is necessary that the ignition switch 2 is on and the relay 3 is on. Since battery power is supplied to the terminal 4 of the second switch 4b via the relay 3,
When operating D (opening operation), terminal 2 → motor 6b
→ terminal 3 → terminal 5 → terminal 6 on the front left side (FRONT LH) of the fifth switch 4a ₂ → lock switch 8 → a closed circuit of ground circuit is formed to drive the motor 6b. Regarding the U operation (closing operation), a closed circuit for the U operation is also formed, and the motor 6b is driven in the opposite direction.

(2) When operating the fifth switch _4a2, which is the main switch, even after the ignition switch 2 is turned off, the relay 5a remains on for a certain period of time, for example, 30 seconds. , battery power is supplied to the terminal 5 of the fifth switch _4a2 . When the U operation (blocking operation) is performed on the front left side (FRONT LH) of the fifth switch _4a2 ,
A closed circuit is formed from terminal 5→terminal 6 to terminal 5 of second switch 4b→terminal 3→motor 6b→terminal ₂ →terminal 1 to terminal 7 of fifth switch 4a2→earth circuit. to drive. Regarding the D operation (closing operation), a closed circuit for the D operation is also formed, and the motor 6b is driven in the opposite direction.

(3) When operating the first switch 4a ₁ In the case of automatic operation, battery power is supplied to the terminal 15 of the hold circuit 7 via the relay 5a, so if you operate U, for example, the terminal 15 → RC ₁ → terminal 13→Switch _4a Current flows to ground through terminal 3→terminal 4 of switch 4a 1, and RC ₁ (relay coil) attracts RL ₁ (relay). On the other hand, since RL ₁ is interlocked with RL ₃ , a circuit is established, and current flows from terminal 15 → RL ₃ → terminal 17 of motor 6a → same terminal 14 → RL ₄ → to ground through the primary side of the transformer, causing motor 6a to rotate. do. On the other hand, at the end of the U operation, the rotation of the motor 6a decreases, the voltage fluctuation occurring between the motor brushes decreases, and RL ₁ , RL ₃
is restored and the rotation of the motor 6a automatically stops.

In the case of manual operation, for example, when the U operation is performed, current flows to ground through terminal 15 of hold circuit 7 → RC ₁ → terminal 13 → terminal 3 of switch 4a ₁ → terminal 4, and in the same way as above, terminal 15 → RL ₃ → Terminal 17 of motor 6a → Terminal 14 → RL ₄ → Current flows from the primary side of the transformer to the ground, and the motor 6a rotates. At the same time, current flows from terminal 15 → R ₁ → R ₂ → R ₇ → Tr ₄ to ground, turning Tr ₄ on. At this time, a current flows from terminal 15 to R18 to Tr ₁ to R ₃ to Tr ₄ , and Tr ₃ is turned off, so the current that maintains RL ₁ does not flow. Therefore, when the switch 4a ₁ is turned off, RL ₁ returns immediately and the rotation of the motor 6a stops.

However, according to the conventional device, even rear seat passengers can operate the power windows by operating the main switch as long as the timer 5 has not passed since the ignition switch was turned off. For example, if there is a child in the rear seat, the window may be opened or closed against the driver's will.

The present invention has been made in view of the above,
When the ignition switch is in the on position, its operation is enabled at all times, and when the ignition switch is turned off, it must be operated within a predetermined time from the time when the ignition switch is turned off, and when the driver's door is closed. To provide a power window control device for a vehicle capable of operating a power window only when the window is opened.

That is, the vehicle power window control device according to the present invention has a door switch that is turned on when the driver's door is opened, a door switch that is turned on during the period when the ignition switch is turned on, and a time period when the ignition switch is turned off. In this case, a switch circuit that turns on when the on signal of the door switch is input within a predetermined time from the off time, and a switch circuit that individually supplies power to a plurality of power window motors when the switch circuit is on. It is equipped with a power window main switch located near the driver's seat.

The vehicle power window control device according to the present invention will be explained in detail below.

FIG. 2 shows an embodiment of the invention. 1st
The same parts as in the figure are indicated by the same quotation numerals, so repeated explanations will be omitted. The timer 5 is turned on and turned off when closed, and the timer 5 is turned on and off using the signal. That is, the timer 5 is turned on when the ignition switch 2 is turned on, and when the ignition switch 2 is turned off, the driver's door is opened and the door switch 5b is turned on at a predetermined time after the ignition switch 2 is turned off. It turns on only when , turning on the relay 5a.

In the above configuration, when the ignition switch 2 is turned on, the relay 3 is turned on, and when the timer 5 is turned on, the relay 5a is turned on, so that the first to fifth switches 4a ₁ , 4b ₂ , b,
Each window can be opened and closed by each operation c and d. However, after the ignition switch 2 is turned off, the timer 5 is turned on and the relay 5a is turned on only when the door switch 5b is turned on at a predetermined time. Therefore, only in that state, the main switches 1 and 5
Each window can be opened and closed from the driver's seat by operating the switches 4a ₁ and 4a ₂ . In other words, if the driver's door is not opened even within the predetermined time set by the timer 5, the door switch 5b is turned off, so the first and fifth switches 4a ₁ , which are the main switches, are turned off. Even if I operate 4a ₂ , I cannot open or close the window. In addition, to prevent the timer from running out while the power windows are operating,
It may be configured to detect the operating current and extend the timer time.

As explained above, according to the vehicle power window control device according to the present invention, when the ignition switch is in the on position, the operation is always possible, and when the ignition switch is turned off, the ignition switch is turned off. Since the power window can be operated only within a predetermined time from the time when the driver's seat door is open, it is possible to prevent the window from being opened or closed against the driver's will.
